                               PROSPECTUS SUMMARY
 
     This summary is qualified by more detailed information appearing in other
sections of this prospectus. The other information is important, so please read
this entire prospectus carefully. Unless otherwise indicated, all information in
this prospectus: (a) gives effect to a 3.4-for-1 reverse stock split that was
completed on February 3, 1997 and (b) assumes that the underwriters do not
exercise their over-allotment option. References to EMCORE's fiscal years refer
to fiscal years ended on September 30.
 
                               EMCORE CORPORATION
 
     EMCORE designs, develops and manufactures compound semiconductor wafers and
devices and is a leading developer and manufacturer of the tools and
manufacturing processes used to fabricate compound semiconductor wafers and
devices. Our products and technology enable our customers, both in the United
States and internationally, to manufacture commercial volumes of
high-performance electronic devices using compound semiconductors. Our products
are used in a wide variety of applications in the communications (satellite,
data, telecommunications and wireless), consumer and automotive electronics,
computers and peripherals, and lighting markets. EMCORE's customers include AMP
Incorporated, Hewlett Packard, General Motors, Hughes-Spectrolab, Lucent
Technologies, Inc., Siemens AG and 12 of the largest electronics manufacturers
in Japan.
 
     Compound semiconductors are the key components of electronic systems and
electronic circuits and are now used in today's most advanced information
systems. Compound semiconductors are composed of two or more elements and
usually consist of a metal such as gallium, aluminum or indium and a non-metal
such as arsenic, phosphorus or nitrogen. These elements are combined in our
proprietary manufacturing process to create a round disk, or wafer, that has
multiple layers of thin films of semiconductors on it. The wafers are further
processed to create devices that are ready to be packaged by our customers for
use in their products, such as solar cells, lasers and transistors. Many
compound semiconductor materials have unique physical properties that allow
electrons to move at least four times faster than through semiconductors based
on silicon. Advantages of compound semiconductor devices over silicon devices
include:
 
     - operation at higher speeds;
 
     - lower power consumption;
 
     - less noise and distortion; and
 
     - the ability to emit and detect light, known as optoelectronic properties.
 
     Although compound semiconductors are more expensive to manufacture than the
more traditional silicon-based semiconductors that are used in most computers,
electronics manufacturers are increasingly integrating compound semiconductors
into their products in order to achieve higher performance.

                                  RISK FACTORS
 
     You should carefully consider the following risks, together with the other
information contained in this prospectus, before you decide whether to purchase
shares of our common stock. If any of the following risks actually occur, our
business, financial condition or results of operations would likely suffer. In
such case, the trading price of our common stock could decline, and you may lose
all or part of the money you paid to buy our common stock.
 
     This prospectus contains forward-looking statements based on our current
expectations, assumptions, estimates and projections about EMCORE and our
industry. These forward-looking statements involve numerous risks and
uncertainties. Our actual results could differ materially from those anticipated
in such forward-looking statements as a result of certain factors, as more fully
described in this section and elsewhere in this prospectus. We undertake no
obligation to update publicly any forward-looking statements for any reason,
even if new information becomes available or other events occur in the future.
 
WE EXPECT TO CONTINUE TO INCUR OPERATING LOSSES.
 
     We started operations in 1984 and as of March 31, 1999 had an accumulated
deficit of $71.2 million. We incurred net losses of $3.2 million in fiscal 1996,
$5.6 million in fiscal 1997, $36.4 million in fiscal 1998 and $10.9 million in
the first six months of fiscal 1999. We expect to continue to incur losses. To
support our growth, we have increased our expense levels and our investments in
inventory and capital equipment. As a result, we will need to significantly
increase revenues and profit margins to become and stay profitable. If our sales
and profit margins do not increase to support the higher levels of operating
expenses and if our new product offerings are not successful, our business,
financial condition and results of operations will be materially and adversely
affected. Please see "Management's Discussion and Analysis of Financial
Condition and Results of Operations" and the Financial Statements and the Notes
thereto for detailed information on our history of losses.
 
OUR RAPID GROWTH PLACES A STRAIN ON OUR RESOURCES.
 
     We are experiencing rapid growth, having added a significant number of new
employees, acquired MicroOptical Devices, Inc., or MODE, and entered into joint
ventures with General Electric Lighting (pending), Uniroyal Technology
Corporation, Optek Technology, Inc. and Union Miniere Inc. We have expanded our
facilities to include two manufacturing facilities in Albuquerque, New Mexico in
addition to our original facility in Somerset, New Jersey. Our joint venture
with Uniroyal Technology Corporation has leased a manufacturing facility in
Tampa, Florida. This growth has placed and will continue to place a significant
strain on our management, financial, sales and other employees and on our
internal systems and controls. If we are unable to effectively manage multiple
facilities and multiple joint ventures in geographically distant locations, our
business, financial condition and results of operations will be materially and
adversely affected. We are also in the process of installing new manufacturing
software for all of our facilities and are evaluating replacing our accounting
and purchasing systems. Most of the new manufacturing software is
 
                                        8
<PAGE>   10
 
customized to our particular business and manufacturing processes. It will take
time and require evaluation to eliminate all of the bugs in the software and to
train personnel to use the new software. In this transition we may experience
delays in production, cost overruns and disruptions in our operations.
 
     Please see "Management's Discussion and Analysis of Financial Condition and
Results of Operations" for more information.
 
SINCE THE TECHNOLOGY IN THE COMPOUND SEMICONDUCTOR INDUSTRY RAPIDLY CHANGES, WE
MUST CONTINUALLY IMPROVE EXISTING PRODUCTS, DESIGN AND SELL NEW PRODUCTS AND
MANAGE THE COSTS OF RESEARCH AND DEVELOPMENT IN ORDER TO EFFECTIVELY COMPETE.
 
     We compete in markets characterized by rapid technological change, evolving
industry standards and continuous improvements in products. Due to constant
changes in these markets, our future success depends on our ability to improve
our manufacturing processes and tools and our products. For example, our
TurboDisc production systems must remain competitive on the basis of cost of
ownership and process performance. To remain competitive we must continually
introduce manufacturing tools with higher capacity and better production yields.
 
     We have recently introduced a number of new products and, in connection
with recent joint ventures and internal development, we will be introducing
additional new products in the near future. The commercialization of new
products involves substantial expenditures in research and development,
production and marketing. We may be unable to successfully design or manufacture
these new products and may have difficulty penetrating new markets. In addition,
many of our new products are being incorporated into our customers' new products
for new applications, such as high speed computer networks.
 
     Because it is generally not possible to predict the amount of time required
and the costs involved in achieving certain research, development and
engineering objectives, actual development costs may exceed budgeted amounts and
estimated product development schedules may be extended. Our business, financial
condition and results of operations may be materially and adversely affected if:
 
     - we are unable to improve our existing products on a timely basis;
 
     - our new products are not introduced on a timely basis;
 
     - we incur budget overruns or delays in our research and development
       efforts; or
 
     - our new products experience reliability or quality problems.
 
FLUCTUATIONS IN OUR QUARTERLY OPERATING RESULTS MAY NEGATIVELY IMPACT OUR STOCK
PRICE.
 
     Our revenues and operating results may vary significantly from quarter to
quarter due to a number of factors particular to EMCORE and the compound
semiconductor industry. Not all of these factors are in our control. These
factors include:
 
     - the volume and timing of orders for our products, particularly TurboDisc
       systems, which have an average selling price in excess of $1 million;
 
                                        9
<PAGE>   11
 
     - the timing of our announcement and introduction of new products and of
       similar announcements by our competitors;
 
     - downturns in the market for our customers' products;
 
     - regional economic conditions, particularly in Asia where we derive a
       significant portion of our revenues; and
 
     - price volatility in the compound semiconductor industry.
 
     These factors may cause our operating results for future periods to be
below the expectations of analysts and investors. This may cause a decline in
the price of our common stock. Please see "Management's Discussion and Analysis
of Financial Condition and Results of Operations" for detailed information on
our annual and quarterly operating results.
 
OUR JOINT VENTURE PARTNERS, WHO HAVE CONTROL OF THESE VENTURES, MAY MAKE
DECISIONS THAT WE DO NOT AGREE WITH AND THAT ADVERSELY AFFECT OUR NET INCOME.
 
     Since December 1997, we have established three joint ventures (with Optek
Technology, Inc., Union Miniere, Inc. and Uniroyal Technology Corporation) and
have signed an agreement to enter into a fourth joint venture with General
Electric Lighting. Certain conditions may not be satisfied and, therefore, it is
possible that this joint venture with General Electric Lighting will not be
established. Failure to consummate this joint venture with General Electric
Lighting could have a material and adverse effect on our business prospects.
 
     Each of our joint ventures involves the creation of a separate company, and
we do not have a majority interest in any of these entities. Each of these joint
ventures is governed by a board of managers with representatives from both the
strategic partner and us. Many fundamental decisions must be approved by both
parties to the joint venture, which means we will be unable to direct the
operation and direction of these joint ventures without the agreement of our
joint venture partners. If we are unable to agree on important issues with a
joint venture partner, the business of that joint venture may be delayed or
interrupted, which may, in turn, materially and adversely affect our business,
financial condition and results of operations.
 
     We have devoted and we will be required to continue to devote significant
funds and technologies to our joint ventures to develop and enhance their
products. In addition, our joint ventures will require that some of our
employees devote much of their time to joint venture projects. This will place a
strain on our management, scientific, financial and sales employees. If our
joint ventures are unsuccessful in developing and marketing their products, our
business, financial condition and results of operations will be materially and
adversely affected.
 
     General Electric Lighting and we have agreed that our joint venture will be
the sole vehicle for each party's participation in the solid state lighting
market. We and General Electric Lighting have also agreed to several limitations
during the life of the venture and thereafter relating to use that each of us
can make of the joint venture's technology. One consequence of these limitations
is that in certain circumstances, such as a material default by us, we would not
be permitted to use the joint venture's technology to compete against General
Electric Lighting in the solid state lighting market.
                                       10

SINCE A LARGE PERCENTAGE OF OUR REVENUES ARE FROM FOREIGN SALES, CERTAIN EXPORT
RISKS MAY DISPROPORTIONATELY AFFECT OUR REVENUES.
    
 
   
     Sales to customers located outside the United States accounted for
approximately 42.5% of our revenues in fiscal 1996, 42.0% of our revenues in
fiscal 1997, 39.1% of our revenues in fiscal 1998 and 40.0% of our revenues in
the first six months of fiscal 1999. Sales to customers in Asia represent the
majority of our international sales. We believe that international sales will
continue to account for a significant percentage of our revenues. Because of
this, the following export risks may disproportionately affect our revenues:
    
 
   
     - political and economic instability may inhibit export of our systems and
       devices and limit potential customers' access to dollars;
    
 
   
     - shipping and installation costs of our systems may increase;
    
 
   
     - we have experienced and may continue to experience difficulties in the
       timeliness of collection of foreign accounts receivable and have been
       forced to write off receivables from a foreign customer;
    
 
   
     - a strong dollar may make our systems less attractive to foreign
       purchasers who may decide to postpone making the capital expenditure;
    
 
   
     - tariffs and other barriers may make our systems and devices less cost
       competitive;
    
 
   
     - we may have difficulty in staffing and managing our international
       operations;
    
 
   
     - the laws of certain foreign countries may not adequately protect our
       trade secrets and intellectual property; and
    
 
   
     - potentially adverse tax consequences to our customers may make our
       systems and devices not cost competitive.
    
 
   
WE WILL LOSE SALES IF WE ARE UNABLE TO OBTAIN GOVERNMENT AUTHORIZATION TO EXPORT
OUR PRODUCTS.
    
 
   
     Exports of our products to certain destinations, such as the People's
Republic of China, Malaysia and Taiwan, may require pre-shipment authorization
from U.S. export control authorities, including the U.S. Departments of Commerce
and State. Authorization may be conditioned on end-use restrictions. On certain
occasions, we have been denied authorization, particularly with respect to the
People's Republic of China. Failure to receive these authorizations may
materially and adversely affect our revenues and in turn our business, financial
condition and results of operations from international sales. Beginning April
1999, exports of all satellites and associated components require a license from
the Department of State. This may cause delays in shipping solar cells abroad.
Delays in receiving export licenses for solar cells may materially and adversely
affect our revenues and in turn our business, financial condition and results of
operations.
    
 
   
THE LOSS OF SALES TO GENERAL MOTORS OR OUR OTHER LARGE CUSTOMERS WOULD BE
DIFFICULT TO REPLACE.
    
 
   
     We derive a substantial portion of our revenues from a limited number of
customers. Sales to Hughes-Spectrolab, primarily of TurboDisc systems and solar
cells,
    
 
                                       11
<PAGE>   13
 
accounted for approximately 23.6% of our revenues in fiscal 1996, 10.2% of our
revenues in fiscal 1997, 17.3% of our revenues in fiscal 1998, but only 3.8% of
our revenues for the first six months of fiscal 1999. We believe that, at least
in the short-term, Hughes-Spectrolab will produce most of its material
requirements in-house using TurboDisc systems purchased from us. Consequently,
we do not expect sales to Hughes-Spectrolab to continue to be significant in the
short term. General Motors, our main customer for MR sensors, accounted for
approximately 15.1% of our revenues in fiscal 1997, 12.8% of our revenues in
fiscal 1998 and 10.8% of our revenues for the first six months of fiscal 1999.
General Motors' three month strike in 1998 adversely affected our operating
performance because during that time shipments of sensors to General Motors were
halted. In addition to the lost revenues, we incurred the expense of paying
salaries to the part of our workforce dedicated to producing sensors. If General
Motors, or any of our other significant customers, stops ordering our products,
significantly reduces the volume of these orders, or cancels, delays or
reschedules any orders, and we are unable to replace these orders, our business,
financial condition and results of operations could be materially and adversely
affected. Please see "Business -- Customers" for more information on our
significant customers.
 
OUR PRODUCTS ARE DIFFICULT TO MANUFACTURE AND SMALL MANUFACTURING DEFECTS CAN
ADVERSELY AFFECT OUR PRODUCTION YIELDS AND OUR OPERATING RESULTS.
 
     The manufacture of our TurboDisc systems is a highly complex and precise
process. We increasingly outsource the fabrication of certain components and
sub-assemblies of our systems, often to sole source suppliers or a limited
number of suppliers. We have experienced occasional delays in obtaining
components and subassemblies because the manufacturing process for these items
is very complex and requires long lead times. The revenues derived from sales of
our TurboDisc systems will be materially and adversely affected if we are unable
to obtain a high quality, reliable and timely supply of these components and
subassemblies. In addition, any reduction in the precision of these components
will result in sub-standard end products and will cause delays and interruptions
in our production cycle.
 
     We manufacture all of our wafers and devices in our manufacturing
facilities and our joint venture with Uniroyal Technology Corporation plans to
manufacture HB LED wafers and package-ready devices at its facility. Minute
impurities, difficulties in the production process, defects in the layering of
the devices' constituent compounds, wafer breakage or other factors can cause a
substantial percentage of wafers and devices to be rejected or numerous devices
on each wafer to be non-functional. These factors can result in lower than
expected production yields, which would delay product shipments and may
materially and adversely affect our operating results. Because the majority of
our costs of manufacture are relatively fixed, the number of shippable devices
per wafer for a given product is critical to our financial results.
Additionally, because we manufacture all of our products at our facilities in
Somerset, New Jersey and Albuquerque, New Mexico, and our joint venture with
Uniroyal Technology Corporation will manufacture HB LED wafers and package-ready
devices at its sole facility in Tampa, Florida, any interruption in
manufacturing resulting from fire, natural disaster, equipment failures or
otherwise would materially and adversely affect our business, financial
condition and results of operations. Please see "Business -- Manufacturing" for
a more detailed description of our manufacturing processes.
 
                                       12
<PAGE>   14
 
WE FACE LENGTHY SALES AND QUALIFICATIONS CYCLES FOR OUR PRODUCTS AND, IN MANY
CASES, MUST INVEST A SUBSTANTIAL AMOUNT OF TIME AND FUNDS BEFORE WE RECEIVE
ORDERS.
 
     Sales of our TurboDisc systems primarily depend upon the decision of a
prospective customer to increase its manufacturing capacity, which typically
involves a significant capital commitment by the customer. Customers usually
place orders with us on average two to nine months after our initial contact
with them. We often experience delays in obtaining system sales orders while
customers evaluate and receive internal approvals for the purchase of these
systems. These delays may include the time necessary to plan, design or complete
a new or expanded compound semiconductor fabrication facility. Due to these
factors, we expend substantial funds and sales, marketing and management efforts
to sell our compound semiconductor production systems. These expenditures and
efforts may not result in sales.
 
     In order to expand our materials production capabilities, we have dedicated
a number of our TurboDisc systems to the manufacture of wafers and devices.
Several of our products are currently being tested to determine whether they
meet customer or industry specifications. During this qualification period, we
invest significant resources and dedicate substantial production capacity to the
manufacture of these new products, prior to any commitment to purchase by the
prospective customer and without generating significant revenues from the
qualification process. If we are unable to meet these specifications or do not
receive sufficient orders to profitably use the dedicated production capacity,
our business, financial condition and results of operations would be materially
and adversely affected. Please see "Business -- Products," "Business --
Marketing and Sales" and "Business -- Competition" for more information on our
products and our marketing and sales efforts.
 
INDUSTRY DEMAND FOR SKILLED EMPLOYEES, PARTICULARLY SCIENTIFIC AND TECHNICAL
PERSONNEL WITH COMPOUND SEMICONDUCTOR EXPERIENCE, EXCEEDS THE NUMBER OF SKILLED
PERSONNEL AVAILABLE.
 
     Our future success depends, in part, on our ability to attract and retain
certain key personnel, including scientific, operational and management
personnel. We anticipate that we will need to hire additional skilled personnel
to continue to expand all areas of our business. The competition for attracting
and retaining these employees, especially scientists, is intense. Because of
this intense competition for these skilled employees, we may be unable to retain
our existing personnel or attract additional qualified employees in the future.
If we are unable to retain our skilled employees and attract additional
qualified employees to keep up with our expansion, our business, financial
condition and results of operations will be materially and adversely affected.
 
PROTECTING OUR TRADE SECRETS IS CRITICAL TO OUR ABILITY TO EFFECTIVELY COMPETE
FOR BUSINESS.
 
     Our success and competitive position depend on protecting our trade secrets
and other intellectual property. Our strategy is to rely more on trade secrets
than patents to protect our manufacturing and sales processes and products, but
reliance on trade secrets is only an effective business practice insofar as
trade secrets remain undisclosed and a proprietary product or process is not
reverse engineered or independently developed. We take certain measures to
protect our trade secrets, including executing non-disclosure agreements with
our employees, joint venture partners, customers and suppliers. If parties
breach these agreements or the measures we take are not properly
                                       13
<PAGE>   15
 
implemented, we may not have an adequate remedy. Disclosure of our trade secrets
or reverse engineering of our proprietary products, processes or devices would
materially and adversely affect our business, financial condition and results of
operations.
 
     Although we currently hold 11 U.S. patents, these patents do not protect
any material aspects of the current or planned commercial versions of our
systems, wafers or devices. We are actively pursuing patents on some of our
recent inventions, but these patents may not be issued. Even if these patents
are issued, they may be challenged, invalidated or circumvented. In addition,
the laws of certain other countries may not protect our intellectual property to
the same extent as U.S. laws. Please see "Business -- Intellectual Property and
Licensing" for more information regarding our trade secrets, patents and other
intellectual property.
 
WE MAY REQUIRE LICENSES TO CONTINUE TO MANUFACTURE AND SELL CERTAIN OF OUR
COMPOUND SEMICONDUCTOR WAFERS AND DEVICES, THE EXPENSE OF WHICH MAY ADVERSELY
AFFECT OUR RESULTS OF OPERATIONS.
 
     We may require licenses from Rockwell International Corporation to continue
to sell our compound semiconductor wafers and devices to current customers who
do not hold licenses from Rockwell International Corporation. In addition, we
may be required to pay royalties for certain of our past sales of wafers and
devices to these customers. If we are required to pay significant royalties in
connection with these sales, our business, financial condition and results of
operations may be materially and adversely affected. The failure to obtain or
maintain these licenses on commercially reasonable terms may materially and
adversely affect our business, financial condition and results of operations.
Please see "Business -- Intellectual Property and Licensing" for more details
regarding our patents and licenses.
 
INTERRUPTIONS IN OUR BUSINESS AND A SIGNIFICANT LOSS OF SALES TO ASIA MAY RESULT
IF OUR PRIMARY ASIAN DISTRIBUTOR FAILS TO EFFECTIVELY MARKET AND SERVICE OUR
PRODUCTS.
 
     We rely on a single marketing, distribution and service provider, Hakuto
Co. Ltd. to market and service many of our products in Japan, China and
Singapore. Hakuto is one of our shareholders and Hakuto's president is a member
of our Board of Directors. We have distributorship agreements with Hakuto which
expire in March 2008 and give Hakuto exclusive distribution rights for certain
of our products in Japan. Hakuto's failure to effectively market and service our
products or termination of our relationship with Hakuto would result in
significant delays or interruption in our marketing and service programs in
Asia. This would materially and adversely affect our business, financial
condition and results of operations.
 
YEAR 2000 PROBLEMS MAY DISRUPT OUR BUSINESS AND THE COSTS TO CORRECT THESE
PROBLEMS MAY BE MATERIAL.
 
     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.
 
                                       14
<PAGE>   16
 
     We have made a preliminary assessment of our Year 2000 readiness. We plan
to perform a Year 2000 simulation on our software during the second and third
calendar quarter of 1999. We are also in the process of contacting certain
third-party vendors, licensors and providers of software, hardware and services
regarding their Year 2000 readiness. Following this testing and after contacting
these vendors and licensors, we will be better able to make a complete
evaluation of Year 2000 readiness, to determine what costs will be necessary to
be Year 2000 compliant and to determine whether contingency plans need to be
developed. We may discover Year 2000 compliance problems in our TurboDisc
systems that will require substantial modifications. In addition, we may
discover that third-party software or hardware incorporated into EMCORE's
TurboDisc systems will need to be revised or replaced, all of which could be
time-consuming and expensive.
 
     Any failure on our part to fix or replace our internally developed
proprietary software or third-party software or hardware or services on a timely
basis could result in lost revenues, increased operating costs, the loss of
customers and other business interruptions. Moreover, we could be subject to
lawsuits which could be costly and time-consuming to defend. The failure of
governmental agencies, utility companies, third party service providers and
others outside of our control to be Year 2000 compliant could result in systemic
failure such as telecommunications or electrical failure, which could have a
material adverse effect on our business, results of operations and financial
condition. Please see "Management's Discussion and Analysis of Financial
Condition" for detailed information on our state of readiness, potential risks
and contingency plans regarding the Year 2000 issue.
 
OUR MANAGEMENT'S STOCK OWNERSHIP GIVES THEM THE POWER TO CONTROL BUSINESS
AFFAIRS AND PREVENT A TAKEOVER THAT COULD BE BENEFICIAL TO UNAFFILIATED
SHAREHOLDERS.
 
     Certain members of our management, specifically Thomas J. Russell, Chairman
of our Board, Reuben F. Richards, President, Chief Executive Officer and a
director, and Robert Louis-Dreyfus, a director, are former members of Jesup &
Lamont Merchant Partners, L.L.C. They collectively beneficially own
approximately 45.9% of our common stock immediately prior to this offering and
will own approximately 34.1% of our common stock after the offering.
Accordingly, such persons will continue to hold sufficient voting power to
control our business and affairs for the foreseeable future. This concentration
of ownership may also have the effect of delaying, deferring or preventing a
change in control of our company, which could have a material adverse effect on
our stock price.
 
UNSUCCESSFUL CONTROL OF THE HAZARDOUS RAW MATERIALS USED IN OUR MANUFACTURING
PROCESS COULD RESULT IN COSTLY REMEDIATION FEES, PENALTIES OR DAMAGES UNDER
ENVIRONMENTAL AND SAFETY REGULATIONS.
 
     The production of wafers and devices involves the use of certain hazardous
raw materials, including, but not limited to, ammonia, phosphine and arsene. If
our control systems are unsuccessful in preventing a release of these materials
into the environment or other adverse environmental conditions occur, we could
experience interruptions in our operations and incur substantial remediation and
other costs. Failure to comply with environmental and health and safety laws and
regulations may materially and adversely affect our business, financial
condition and results of operations.
 
                                       15
<PAGE>   17
 
   
OUR BUSINESS OR OUR STOCK PRICE COULD BE ADVERSELY AFFECTED BY REDEMPTION OF
OUTSTANDING CONVERTIBLE PREFERRED STOCK OR ISSUANCE OF ADDITIONAL PREFERRED
STOCK.
    
 
   
     We have 1,550,000 shares of convertible preferred stock issued and
outstanding, all of which are subject to mandatory redemption by us on November
17, 2003. If we do not have the funds available to redeem the convertible
preferred stock at that time, we will need to raise additional funds to finance
this redemption or we will be in default under the terms of the convertible
preferred stock. We may be unable to obtain adequate financing on acceptable
terms, which may adversely affect our business and financial condition.
    
 
   
     Our board of directors is authorized to issue up to an additional 4,332,353
shares of preferred stock with such dividend rates, liquidation preferences,
voting rights, redemption and conversion terms and privileges as our board of
directors, in its sole discretion, may determine. The issuance of additional
shares of preferred stock may result in a decrease in the value or market price
of our common stock, or our board of directors could use the preferred stock to
delay or discourage hostile bids for control of us in which shareholders may
receive premiums for their common stock or to make the possible sale of the
company or the removal of our management more difficult. The issuance of
additional shares of preferred stock could adversely affect the voting and other
rights of the holders of common stock.
    
 
   
CERTAIN PROVISIONS OF NEW JERSEY LAW AND OUR CHARTER MAY MAKE A TAKEOVER OF OUR
COMPANY DIFFICULT EVEN IF SUCH TAKEOVER COULD BE BENEFICIAL TO SOME OF OUR
SHAREHOLDERS.
    
 
   
     New Jersey law contains and our certificate of incorporation, as amended,
contains certain provisions that could delay or prevent a takeover attempt that
our shareholders may consider in their best interests. Our board of directors is
divided into three classes. Directors are elected to serve staggered three-year
terms and are not subject to removal except for cause by the vote of the holders
of at least 80% of our capital stock. In addition, if these amendments are
adopted, approval by the holders of 80% of our voting stock is required for
certain business combinations unless these transactions meet certain fair price
criteria and procedural requirements or are approved by two-thirds of our
continuing directors. We may in the future adopt other measures that may have
the effect of delaying or discouraging an unsolicited takeover, even if the
takeover were at a premium price or favored by a majority of unaffiliated
shareholders. Certain of these measures may be adopted without any further vote
or action by our shareholders.
    
 
   
FUTURE SALES BY EXISTING SHAREHOLDERS COULD DEPRESS THE MARKET PRICE OF OUR
COMMON STOCK AND MAKE IT MORE DIFFICULT FOR US TO SELL STOCK IN THE FUTURE.
    
 
   
     If our shareholders sell substantial amounts of our common stock in the
public market following this offering, the market price of our common stock
could fall. These sales also might make it more difficult for us to sell equity
or equity-related securities in the future at a time and price that we deem
appropriate. Upon completion of this offering, we will have 13,014,204 shares of
common stock outstanding (based on the number of shares outstanding as of May 1,
1999 and assuming no exercise of outstanding options or warrants). Of these
shares, 5,600,226 shares are freely tradeable. This leaves 5,887,883 shares
eligible for sale in the public market at various times after the date of this
prospectus pursuant to Rule 144.
    
 
   
     In addition, as of May 1, 1999, stock options to purchase 1,143,293 shares
of our common stock, warrants to purchase 1,371,262 shares of our common stock
and 1,550,000 shares of our convertible preferred stock, which are convertible
into shares of common stock on a one-for-one basis, were outstanding. In
connection with our joint

venture with General Electric Lighting, we will issue to General Electric common
stock purchase warrants at an exercise price of $22.875 to acquire 282,010
shares of common stock, and a $7.8 million subordinated convertible debenture
with an interest rate of 4.75% per annum due in seven years. The debenture will
be convertible into 340,984 shares of common stock at a conversion price equal
to $22 7/8.
 
     Certain shareholders, representing approximately 6,240,585 shares of our
common stock (including shares of common stock issuable upon conversion of our
convertible preferred stock and warrants) have the right to require us to
register their shares. We agreed to file a shelf registration, for the benefit
of the holders of our convertible preferred stock and those holders of up to
5,210,585 shares of common stock who choose to participate, 90 days after
completion of this offering. This shelf registration will remain effective until
November 17, 2003 or such earlier time as all of the shares of our convertible
preferred stock and the common stock issued upon conversion thereof are no
longer restricted under Rule 144.

                                USE OF PROCEEDS
 
     The net proceeds to EMCORE from the sale of the 3,000,000 shares of common
stock being offered by EMCORE are estimated to be $54.5 million ($66.0 million
if the underwriters' over-allotment option is exercised in full), assuming a
public offering price of $19.63 per share and after deducting the underwriting
discounts and commissions and estimated offering expenses. EMCORE will not
receive any proceeds from the sale of shares of common stock by the selling
shareholders. EMCORE intends to use $27.5 million to repay outstanding bank
indebtedness to First Union National Bank under two credit facilities,
approximately $8.8 million to repay subordinated notes to an affiliate and other
investors, and the balance for general corporate purposes, including working
capital.
 
     The two credit facilities have the following principal amounts, interest
rates, maturity dates and use of proceeds:

                                                                               the Chairman of the Board of EMCORE,

</TABLE>
 
     When the debt is extinguished, there will be an extraordinary charge in
1999 of approximately $700,000 related to the early extinguishment of debt.
 
     The subordinated notes were issued in May and September of 1996, bear
interest at 6.0% and mature on May 1, 2001. Thomas Russell holds approximately
$8.4 million of the subordinated notes that are being repaid. The balance of the
subordinated notes being repaid are held by approximately ten other
non-affiliated investors.
 
     We may also use a portion of the net proceeds to fund acquisitions of
complementary businesses, products or technologies in the semiconductor sector.
Although we periodically review potential acquisition opportunities, we have not
reached any agreements, commitments or understanding for any future
acquisitions. Pending such uses, the net proceeds of this offering will be
invested in short-term, investment-grade, income producing investments.
 
     We believe that the remaining net proceeds from this offering will be
sufficient to fund our anticipated capital expenditures and to provide adequate
working capital at least through July 2000. However, future events may require
EMCORE to seek additional capital which may not be available on terms acceptable
to us.

                      SELECTED CONSOLIDATED FINANCIAL DATA
 
     The following selected consolidated financial data for the six months ended
March 31, 1998 and 1999 and the five fiscal years ended September 30, 1998 of
EMCORE is qualified by reference to and should be read in conjunction with the
Financial Statements and the Notes thereto, and Management's Discussion and
Analysis of Financial Condition and Results of Operations included elsewhere in
this prospectus. The Statement of Income Data set forth below with respect to
fiscal 1996, 1997 and 1998 and the Balance Sheet Data as of September 30, 1997
and 1998 are derived from EMCORE's audited financial statements included
elsewhere in this prospectus. The Statement of Income Data for fiscal 1994 and
1995 and the Balance Sheet Data as of September 30, 1994, 1995 and 1996 are
derived from audited financial statements not included herein. The financial
data as of March 31, 1999 and for the six months ended March 31, 1998 and 1999
are derived from unaudited consolidated financial statements that, in the
opinion of EMCORE's management, reflect all adjustments (consisting only of
normal recurring adjustments) necessary for a fair presentation of the financial
position and results of operations for these periods. Operating results for the
six months ended March 31, 1999 are not necessarily indicative of the results
that may be expected for the entire fiscal year ending September 30, 1999.
 
     On December 5, 1997, the Company acquired MODE in a stock transaction
accounted for under the purchase method of accounting for a purchase price of
$32.8 million. In connection with this transaction, the Company recorded a
non-recurring, non-cash charge of $19.5 million for acquired in-process research
and development, which affects the comparability of the Company's operating
results and financial condition.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
INTRODUCTION
 
     Subsequent to the issuance of EMCORE's Annual Report on Form 10-K for the
year ended September 30, 1998, EMCORE's management revised the amount of the
purchase price which was allocated to in-process research and development in
accounting for the acquisition of MicroOptical Devices, Inc., MODE, in December
1997. The revised allocation is based upon methods prescribed in a letter from
the SEC sent to the American Institute of Certified Public Accountants. The
letter sets forth the SEC's views regarding the valuation methodology to be used
in allocating a portion of the purchase price to acquired in-process research
and development, IPR&D, at the date of acquisition.
 
     The revised valuation is based on management's estimates of the net cash
flows associated with expected operations of MODE and gives explicit
consideration to the SEC's views on acquired IPR&D as set forth in its letter to
the American Institute of Certified Public Accountants.
 
     As a result of the revised allocation, EMCORE's financial statements for
the year ended September 30, 1998 have been restated from amounts previously
reported to reduce the amount of the acquired in-process research and
development expensed by $9.8 million and to increase goodwill by $9.8 million.
The amount allocated to goodwill includes approximately $0.5 million related to
the value of MODE's workforce. The change had no impact on net cash flows used
by operations.
 
     The information included in "Selected Financial Data," and in the
discussion following reflect the effects of this restatement. Refer to Note 20
to the consolidated financial statements for further discussion.
 
OVERVIEW
 
     EMCORE designs, develops and manufactures compound semiconductor materials
and is a leading developer and manufacturer of the tools and manufacturing
processes used to fabricate compound semiconductor wafers and devices. Prior to
fiscal 1997, EMCORE's revenues consisted primarily of the sales of compound
semiconductor production systems. In fiscal 1997, EMCORE expanded its product
offerings to include the design and high-volume production of compound
semiconductor wafers and package-ready devices. EMCORE's vertically-integrated
product offering allows it to provide a complete compound semiconductor solution
to its customers. EMCORE assists its customers with device design, process
development and optimal configuration of TurboDisc production systems.
 
     Systems-related revenues include sales of EMCORE's TurboDisc production
systems as well as spare parts and services. The book-to-ship time period on
systems is approximately four to six months, and 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 for
systems and average selling prices vary significantly based on the products and
services provided. Generally, EMCORE achieves a higher gross profit on its
materials related products.
 
                                       23
<PAGE>   25
 
     EMCORE recognizes revenue upon shipment. For systems, EMCORE incurs certain
installation and warranty costs subsequent to shipment which are estimated and
accrued at the time the sale is recognized. EMCORE reserves for estimated
returns and allowances at the time of shipment. For research contracts with the
U.S. government and commercial enterprises with durations greater than six
months, EMCORE recognizes revenue to the extent of costs incurred plus a pro
rata portion of estimated gross profit as stipulated in these contracts, based
on contract performance. EMCORE's research contracts require the development or
evaluation of new materials applications and have a duration of six to 36
months. 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 have
been incurred and the research reporting requirements to the customer have been
met.
 
     EMCORE has recently established a number of strategic relationships through
joint ventures, long-term supply agreements and an acquisition as summarized
below.
 
     - In May 1999, Sumitomo Electric and EMCORE entered into a long-term
       agreement to jointly develop and produce certain RF materials for use in
       digital wireless and cellular applications. EMCORE will manufacture these
       RF materials at our Somerset, New Jersey manufacturing facility. Sumitomo
       Electric will market them in Japan. Sumitomo Electric is one of the
       world's leading electronics manufacturers. Shipments of these RF
       materials are expected to begin in June 1999.
 
     - In January 1999, EMCORE signed an agreement with General Electric
       Lighting to form GELcore, a joint venture to develop and market white
       light and colored HB LEDs lighting products. GELcore's long-term goal is
       to develop HB LED products to replace traditional lighting. We anticipate
       investing approximately $7.8 million in GELcore upon formation of the
       joint venture and will second various personnel to the joint venture to
       assist in the development and marketing of its products. These personnel
       and the related costs will be charged to the joint venture. In addition,
       GELcore will hire its own administrative and management personnel. As
       such, the impact on EMCORE's operations will be limited to the seconded
       employees who will continue to be managed by EMCORE personnel.
 
     - In November 1998, EMCORE signed a long term purchase agreement with Space
       Systems/Loral, a wholly owned subsidiary of Loral Space & Communications.
       Under this agreement, which is contingent upon EMCORE's compliance with
       Loral's product specification requirements, EMCORE will supply compound
       semiconductor high-efficiency gallium arsenide solar cells for Loral's
       satellites. EMCORE anticipates completing this qualification in June
       1999. Subject to the product qualification, EMCORE received an initial
       purchase order for $5.25 million of solar cells. EMCORE expects to
       service this agreement through our newly completed facility in
       Albuquerque, New Mexico. This facility presently employs approximately 40
       people, including sales, marketing, administrative and manufacturing
       personnel.
 
     - In November 1998, EMCORE formed UMCore, a joint venture with Union
       Miniere Inc., a mining and materials company, to explore and develop
       alternate uses for germanium using EMCORE's materials science and
       production platform expertise and Union Miniere's access to and
       experience with
 
                                       24
<PAGE>   26
 
       germanium. EMCORE has invested $600,000 in UMCore which, together with an
       equal amount funded by Union Miniere, is expected to fund the operations
       of UMCore through fiscal 1999. EMCORE will second various personnel to
       the joint venture to assist in the development of products. Thereafter,
       any additional funding will be contributed equally.
 
     - In October 1998, EMCORE formed Emtech, a joint venture with Optek
       Technology, Inc., a packager and distributor of optoelectronic devices,
       to market an expanded line of magneto resistive sensors to the automotive
       and related industries. This joint venture combines EMCORE's expertise in
       the manufacture of magneto resistive die and Optek's expertise in
       packaging these die. This combination will allow us to offer customers
       off-the-shelf products. No additional personnel are anticipated to meet
       the obligations to the joint venture.
 
     - In September 1998, EMCORE entered into an agreement with Lockheed Martin
       to provide technical management and support for the commercialization of
       a new high-efficiency solar cell. It is anticipated that we will provide
       high efficiency solar cells to Lockheed Martin upon completion of the
       research and development agreement. EMCORE's new facility in Albuquerque,
       New Mexico, will provide the support necessary to meet our obligations
       under this agreement.
 
     - EMCORE also signed a four-year purchase agreement with AMP Incorporated
       to provide high speed VCSELs, for use in transceivers for high speed
       networks that link computers. The contract requires AMP to purchase a
       minimum of 80% of their VCSEL needs from EMCORE. EMCORE's MODE facility
       in Albuquerque, New Mexico, will produce the devices under this contract.
 
     - In February 1998, EMCORE and Uniroyal Technology Corporation formed
       Uniroyal Optoelectronics, a joint venture to manufacture, sell and
       distribute HB LED wafers and package-ready devices. This joint venture
       commenced operations in July 1998. EMCORE has invested $5.5 million in
       Uniroyal Optoelectronics. Uniroyal Optoelectronics is hiring its own
       administrative and management personnel. The impact on EMCORE's
       operations will be limited to a few seconded employees who will continue
       to be managed by EMCORE personnel.
 
     - To expand its technology base into the data communications and
       telecommunications markets, on December 5, 1997, EMCORE acquired MODE in
       a stock transaction accounted for under the purchase method of accounting
       for a purchase price of $32.8 million. These operations are located in
       Albuquerque, New Mexico and currently employ approximately 40 people
       including sales, marketing, administrative and manufacturing personnel.
 
     Because we do not have a controlling economic and voting interest in the
Uniroyal, Union Miniere, Optek and General Electric Lighting joint ventures,
EMCORE will account for these joint ventures under the equity method of
accounting and, as such, our share of profits and losses will be included below
the operating income line in our statement of operations.
 
     EMCORE sells its products and has generated a significant portion of its
sales to customers outside the United States. In fiscal 1996, 1997, 1998 and the
first six
 
                                       25
<PAGE>   27
 
months of fiscal 1999, international sales constituted 42.5%, 42.0%, 39.1% and
40.0%, respectively, of revenues. In fiscal 1998, the majority of EMCORE's
international sales were made to customers in Asia, particularly in Japan.
EMCORE's sales revenues from Europe have f luctuated because most of our sales
of TurboDisc systems are to a limited number of customers, who do not purchase
these systems regularly. EMCORE anticipates that international sales will
continue to account for a significant portion of revenues. Historically, we have
received all payments for products and services in U.S. dollars. We do not
anticipate that Europe's Euro-currency conversion will have a material effect on
our financial condition or results of operations.
 
     The information below summarizes EMCORE's export sales by geographic area.
EMCORE's export sales to the Far East and Europe are as follows:

     As of March 31, 1999, EMCORE had an order backlog of $38.3 million
scheduled to be shipped through March 31, 2000. This represented an increase of
69% since September 30, 1998 which primarily relates to increased systems
bookings in Asia and an initial order for solar cells from Loral, which is
subject to product qualification. EMCORE includes in backlog only customer
purchase orders that have been accepted by EMCORE and for which shipment dates
have been assigned within the 12 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. EMCORE
receives partial advance payments or irrevocable letters of credit on most
production system orders.

COMPARISON OF SIX MONTHS ENDED MARCH 31, 1998 AND 1999
 
RESULTS OF OPERATIONS:
 
     Revenues.  For both the six-month periods ended March 31, 1998 and 1999,
revenues were $26.2 million. Revenues from systems-related sales and
materials-related sales were $14.4 million and $11.7 million, respectively, for
the six months ended March 31, 1998 and $20.6 million and $5.6 million,
respectively, for the six months ended March 31, 1999. As a percentage of
revenues, production systems and wafers and devices accounted for 55.2% and
44.8%, respectively, for the six months ended March 31, 1998 and 78.8% and
21.2%, respectively, for the six months ended March 31, 1999. EMCORE expects
these percentages to approach 50% in each category as its new products such as
solar cells, VCSELS and HBT's are introduced and production ramps. International
sales accounted for 43.5% of revenues for the six months ended March 31, 1998
and 45.5% of revenues for the six months ended March 31, 1999.
 
                                       27
<PAGE>   29
 
     Cost Of Sales/Gross Profit.  Cost of sales includes direct material and
labor costs, allocated manufacturing and service overhead, and installation and
warranty costs. EMCORE's gross profit decreased 10.4% from $12.3 million for the
six months ended March 31, 1998, to $11.0 million for the six months ended March
31, 1999. The decrease was due principally to EMCORE's sale of three compound
semiconductor production systems for approximately $5.3 million to a joint
venture in which it has a 49% minority interest. EMCORE eliminated $1.3 million
of gross profit on these sales, which deferred gross profit will be recognized
ratably over the assigned life of the production systems purchased by the joint
venture.
 
     Selling, General and Administrative.  Selling, general and administrative
expenses increased by 10.7% from $5.8 million for the six months ended March 31,
1998 to $6.4 million in the six months ended March 31, 1999. As a percentage of
revenue, selling, general and administrative expenses increased from 22.0% for
the six months ended March 31, 1998 to 24.3% for the six months ended March 31,
1999. A significant portion of the increase was due to increases in sales
personnel headcount to support both domestic and foreign markets and general
headcount additions to sustain internal administrative support.
 
     Goodwill Amortization.  EMCORE recognized approximately $2.2 million of
goodwill amortization for the six months ended March 31, 1999 in connection with
the acquisition of MODE on December 5, 1997. As of March 31, 1999, EMCORE had
approximately $7.3 million of goodwill remaining, which will be fully amortized
by December 2000.
 
     Research and Development.  Research and development expenses increased
74.8% from $5.9 million in the six months ended March 31, 1998 to $10.3 million
in the six months ended March 31, 1999. As a percentage of revenue, recurring
research and development expenses increased from 22.5% for the six months ended
March 31, 1998 to 39.2% for the six months ended March 31, 1999. The increase
was primarily attributable to EMCORE's acquisition of MODE, the startup of our
new Albuquerque, New Mexico facility 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 production systems, VCSELs, RF materials and
other optoelectronic devices. During the six months ended March 31, 1998, EMCORE
recognized a $19.5 million one-time charge for acquired in-process research and
development relating to the purchase of MODE. To maintain growth and to continue
to pursue market leadership in materials science technology, EMCORE expects to
continue to invest a significant amount of its resources in research and
development.
 
     Operating Loss.  EMCORE reported an operating loss of $7.9 million for the
six months ended March 31, 1999, as compared to an operating loss of $20.3
million for the six months ended March 31, 1998. The change in operating loss
was principally due to the $19.5 million one-time charge for acquired in-process
research and development in 1998, offset by the elimination of $1.3 million of
gross profit in 1999 on the three compound semiconductor production systems sold
to a joint venture in which it has a 49% minority interest. In addition,
EMCORE's 1999 operating loss was impacted by increased research and development
spending, the loss generated from the
 
                                       28
<PAGE>   30
 
operations of MODE and the startup expenses associated with the opening of
EMCORE's new Albuquerque, New Mexico facility.
 
     Other Expense.  During fiscal 1996, EMCORE issued detachable warrants along
with subordinated notes to certain of its existing shareholders. EMCORE
subsequently assigned a value to these detachable warrants issued using the
Black-Scholes option pricing model. EMCORE recorded the subordinated notes at a
carrying value that is subject to periodic accretions, using the interest
method. In June 1998, EMCORE issued 284,684 warrants to its Chairman and its
Chief Executive Officer for providing a guarantee in connection with an 18-month
credit facility with First Union National Bank. EMCORE also assigned a value to
these warrants using the Black-Scholes option pricing model. The consequent
expense of these warrant accretion amounts is charged to "Imputed warrant
interest, non-cash" and equals approximately $192,000 and $633,000 for the six
months ended March 31, 1998 and March 31, 1999, respectively.
 
     For the six months ended, March 31, 1999, stated interest expense, net
increased by $577,000 to $693,000 due to additional borrowing.
 
     Because EMCORE does not have a controlling economic and voting interest in
the Uniroyal, Union Miniere, and General Electric Lighting joint ventures,
EMCORE accounts for these joint ventures under the equity method of accounting.
For the six months ended March 31, 1999, EMCORE incurred a net loss of $1.0
million related to the Uniroyal joint venture, a $497,000 net loss related to
the GELCore joint venture and a $141,000 net loss related to the UMCore joint
venture.
 
     Net Loss.  For the six months period March 31, 1999, EMCORE reported net
loss of $10.9 million, a decrease of 47.5% from a $20.7 million net loss for the
six months ended March 31, 1998. The decrease in the year-to-date loss was
attributable to the $19.5 million write-off of acquired in-process research and
development in connection with the acquisition of MODE on December 5, 1997
offset in part by an increase in research and development expenses and the net
loss from unconsolidated affiliates.
 
COMPARISON OF FISCAL YEARS ENDED SEPTEMBER 30, 1997 AND 1998
 
     Revenues.  EMCORE'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 revenue, as
shipments to General Motors were halted during the strike. Revenues relating to
TurboDisc systems were $34.1 million for the fiscal year ended September 30,
1997 and $26.5 million for the fiscal year ended September 30, 1998. Revenues
relating to wafers and devices were $13.7 million for the fiscal year ended
September 30, 1997 and $17.3 million for the fiscal year ended September 30,
1998. As a percentage of revenues, TurboDisc systems accounted for 71.4% for the
fiscal year ended September 30, 1997 and 60.5% for the fiscal year
 
                                       29
<PAGE>   31
 
ended September 30, 1998. As a percentage of revenues, wafers and devices
accounted for 28.6% for the fiscal year ended September 30, 1997 and 39.5% for
the fiscal year ended September 30, 1998. International sales accounted for
approximately 42.0% and 39.1% of revenues for the fiscal years ended September
30, 1997 and 1998, 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 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 EMCORE's expanded product lines and new
locations. During fiscal 1998, EMCORE 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.
 
     Goodwill Amortization.  In connection with the purchase of MODE, EMCORE
recorded goodwill of $3.4 million which is being amortized over 36 months.
Goodwill amortization expense amounted to $3.6 million for the year ended
September 30, 1998. Net goodwill at September 30, 1998 was $9.5 million.
 
     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 EMCORE'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 production systems, VCSELs and
other optoelectronic devices. For the year ended September 30, 1998, EMCORE
incurred $1.1 million of research and development costs associated with MODE's
in-process (at the date of acquisition) research and development projects. As a
percentage of revenue, research and development expenses increased from 18.8% of
revenue during fiscal 1997 to 37.7% of revenue for fiscal 1998. To maintain
growth and market leadership in epitaxial technology, EMCORE expects to continue
to invest a significant amount of its resources in research and development.
 
     In connection with the MODE acquisition, EMCORE incurred a one-time charge
for the write-off of acquired in-process research and development amounting to
$19.5 million.
 
     The acquisition of MODE, a development stage company, constituted a
significant and strategic investment for EMCORE. The principal investment
consideration was to acquire and gain access to MODE's micro-optical technology,
which was under development at the time. EMCORE plans to use MODE's
micro-optical laser technology in new products for data communications and
telecommunications
 
                                       30
<PAGE>   32
 
applications. As of the date of acquisition, MODE was engaged in the following
six significant VCSEL research and development projects:
 
         - Gigalase -- a high speed (modulation), near-infrared single optical
           laser component for serial selica fiber optic applications.
 
         - Visilase -- a visible, red light, single optical laser component to
           be used for fiber optic links and optical storage and identification.
 
         - Gigarray -- an array of optical lasers to be used in transmission in
           parallel optical interconnects.
 
         - Microscan -- an integrated near-infrared optical laser, visible laser
           and focusing element.
 
         - Optical Laser Source Module (OLSM) -- incorporates optical lasers and
           fast detector specialized circuitry and electronics.
 
         - Optical Laser Array Source Module (OLASM) -- incorporates optical
           lasers, array detection and specialized circuitry and electronics.
 
     The value assigned to each project and the estimated time and cost to reach
technological feasibility was as follows (in $000's):

     The fair value assumptions relating to pricing, product margins and expense
levels were based upon management's experience with its own operations and the
compound semiconductor industry as a whole. In developing EMCORE's future
estimated revenues and costs, new product introductions were expected to
commence in calendar 1998 and net cash flows were expected to commence in
calendar 1999 and 2000. In determining fair value of the acquired projects, a
risk-adjusted discount rate of 20% was utilized. EMCORE has capitalized
approximately $0.5 million for MODE's workforce, which is included in goodwill.
 
     If all of MODE's in-process projects are not successfully completed and if
management's estimated product pricing and growth rates are not achieved, EMCORE
may not realize the product, market and financial benefits expected from the
MODE acquisition.
 
     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 $34.6
million for the year ended September 30, 1998. The change in operating loss was
primarily due to the $19.5 million one-time charge for in-process research and
development written off in connection with the purchase of MODE. Additionally,
recurring research and
 
                                       31
<PAGE>   33
 
development expense increased by $7.5 million from the prior year, as a result
of increased research and development activities at MODE and in our core
business. 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 EMCORE's largest customers. EMCORE was unable to
furlough or reduce their workforce during the strike and thereby incurred
charges without the benefit of related revenues.
 
     Other Expense.  Other expenses decreased, particularly due to the reduced
imputed warrant interest expense associated with EMCORE's subordinated debt and
debt issuance guarantee cost. During fiscal 1996, EMCORE issued detachable
warrants along with subordinated notes to certain of its existing shareholders.
In fiscal year 1997, EMCORE also issued detachable warrants in return for a
$10.0 million demand note facility guarantee by the Chairman of the Board of
EMCORE, who provided collateral for the facility. EMCORE subsequently assigned a
value to these detachable warrants issued using the Black-Scholes option pricing
model. EMCORE 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 $370,000 for the fiscal years ended September 30, 1997 and
1998, respectively. In June 1998, EMCORE 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 First Union
National Bank. EMCORE assigned a value to these warrants using the Black-Scholes
option pricing model. As a result, EMCORE will record imputed warrant interest,
non-cash of approximately $1.3 million over the life of the credit facility.
 
     Income Taxes.  EMCORE'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, EMCORE has net operating loss carryforwards for
regular tax purposes of approximately $22.0 million which expire in the years
2003 through 2013. EMCORE 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. Due to the change in control, EMCORE'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 Internal Revenue Code Section 382 and 383.
 
     EMCORE 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 Internal Revenue Code. As such, federal net
operating loss carryovers and research credit carryovers incurred subsequent to
EMCORE's fiscal 1995 change in control (as described above) will also be subject
to annual limitations under Internal Revenue Code Sections 382 and 383.
 
                                       32
<PAGE>   34
 
     Extraordinary Item.  In the fiscal year ended September 30, 1997, EMCORE
repaid $2.0 million of its outstanding subordinated notes due May 1, 2001. In
connection with this discharge of EMCORE'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 from $5.6 million for the fiscal year ended
September 30, 1997 to $36.4 million for the fiscal year ended September 30,
1998. This increase was primarily attributable to the acquisition of MODE and
subsequent write-off of in-process research and development of $19.5 million as
well as an increase in recurring research and development expenses of $7.5
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.  EMCORE's revenues for fiscal 1997 increased 71.9% from $27.8
million for the fiscal year ended September 30, 1996 to $47.8 million. The
revenue increase was primarily attributable to increased demand for compound
semiconductor production systems and package-ready devices, as well as the
introduction of compound semiconductor wafer products. Revenues relating to
TurboDisc systems were $23.8 million for the fiscal year ended September 30,
1996 and $34.1 million for the fiscal year ended September 30, 1997. Revenues
relating to wafers and devices were $4.0 million for the fiscal year ended
September 30, 1996 and $14.7 million for the fiscal year ended September 30,
1997. As a percentage of revenues, TurboDisc systems accounted for 85.6% for the
fiscal year ended September 30, 1996 and 71.4% for the fiscal year ended
September 30, 1997. As a percentage of revenues, wafers and devices accounted
for 14.4% for the fiscal year ended September 30, 1996 and 28.6% for the fiscal
year ended September 30, 1997. 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 increases in sales personnel headcount to support both domestic
and foreign markets and general headcount additions to sustain the internal
administrative support necessary for EMCORE'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 related to wafers and package-ready
devices. As a
 
                                       33
<PAGE>   35
 
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, EMCORE expects to continue
to invest a significant amount of its resources in research and development.
 
     Operating Loss.  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, EMCORE issued detachable warrants along
with subordinated notes to certain of its existing shareholders. In the first
quarter of fiscal year 1997, EMCORE also issued detachable warrants in return
for the $10.0 million facility guarantee by the Chairman of the Board of EMCORE,
who provided collateral for the Facility. EMCORE subsequently assigned a value
to these detachable warrants issued using the Black-Scholes option pricing
model. EMCORE 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.
 
     Borrowings totaling $8.0 million under the facility were utilized to fund
capital expenditures in connection with the build-out of EMCORE'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.  EMCORE repaid $10.0 million of its outstanding debt
with proceeds from its initial public offering. The entire $8.0 million
outstanding of its credit facility was repaid and $2.0 million was used to repay
a portion of EMCORE's outstanding subordinated notes due May l, 2001. In
connection with this discharge of EMCORE'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 $4.0 million
of non-cash imputed warrant interest associated with certain financing
transactions.

QUARTERLY RESULTS OF OPERATIONS
 
     The following tables present EMCORE's unaudited results of operations
expressed in dollars and as a percentage of revenues for the ten most recently
ended fiscal quarters. EMCORE believes that all necessary adjustments,
consisting only of normal recurring adjustments, have been included in the
amounts below to present fairly the selected quarterly information when read in
conjunction with the consolidated financial statements and notes included
elsewhere in this prospectus. EMCORE's results from operations may vary
substantially from quarter to quarter. Accordingly, the operating results for a
quarter are not necessarily indicative of results for any subsequent quarter or
for the full year.

     From inception through December 31, 1996, EMCORE derived the majority of
its revenues from the sale of TurboDisc production systems. Beginning in January
1997, EMCORE expanded its product line to offer wafers and devices. Throughout
fiscal 1997 and the first half of fiscal 1998, EMCORE benefited from the
expanded product offerings. Early in fiscal 1998, the capital equipment market
experienced a downturn and bookings of TurboDisc systems decreased
substantially. The result was lower revenues for the last two quarters of fiscal
1998 and the first quarter of fiscal 1999.
 
     Cost of sales was also affected by revenue shifts. Gross profit improved
consistently from the introduction of the new product lines through the second
quarter of fiscal 1998. Thereafter, gross profit was affected primarily by
reduced revenues and the resulting under-absorbed overhead.
 
     Operating expenses have generally increased both in absolute dollars and as
a percentage of revenues, due to increased staffing in research and development,
sales and marketing, and general and administrative functions. The increase in
research expenditures was related to the development of systems for the
processing of gallium nitride materials used in the production of blue HB LEDs,
enhancement of production systems, and the introduction of wafers and devices,
in particular, MR sensors,
 
                                       36
<PAGE>   38
 
VCSELs and solar cells. Selling, general and administrative expenses increased
as a result of increased marketing and sales related activities, including the
hiring of additional personnel, commissions, customer samples, expansion of
facilities, and the opening of field offices in Taiwan and California.
 
     EMCORE has experienced and expects to continue to experience significant
fluctuations in quarterly results. Factors which have had an influence on and
may continue to influence EMCORE's operating results in a particular quarter
include, but are not limited to the timing of receipt of orders, cancellation,
rescheduling or delay in product shipment or supply deliveries, product mix,
competitive pricing pressures, EMCORE's ability to design, manufacture and ship
products on a cost effective and timely basis, including the ability of EMCORE
to achieve and maintain acceptable production yields for wafers and devices,
regional economic conditions and the announcement and introduction of new
products by EMCORE and by its competitors. The timing of sales of EMCORE's
TurboDisc production systems may cause substantial fluctuations in quarterly
operating results due to the substantially higher per unit price of these
products relative to EMCORE's other products. If the compound semiconductor
industry experiences downturns or slowdowns, EMCORE's business, financial
condition and results of operations may be materially and adversely affected.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     Cash and cash equivalents decreased by $2.8 million from $4.5 million at
September 30, 1998 to $1.6 million at March 31, 1999. For the six months ended
March 31, 1999, net cash used for operations amounted to $5.9 million, primarily
due to EMCORE's net losses and an increase in accounts receivable which was
partially offset by EMCORE's non-cash depreciation and amortization charges and
an increase in advance billings.
 
     For the six months ended March 31, 1999, net cash used for investment
activities amounted to $16.2 million, primarily due to the purchase and
manufacture of new equipment for the facilitation of EMCORE's wafer and device
product lines, and clean room modifications and enhancements of approximately
$10.4 million, as well as investments in unconsolidated affiliates of
approximately $5.8 million.
 
     Net cash provided by financing activities for the six months ended March
31, 1999 amounted to approximately $19.2 million, primarily due to the $21.2
million of net proceeds from the private placement of preferred stock in
November 1998 and short-term related party borrowings of $5.1 million. This was
offset by debt repayments of $7.0 million on short-term related party debt.
 
     EMCORE's Chairman has committed to provide up to $30.0 million of long-term
financing to EMCORE through July 1, 2000. This commitment terminates upon
completion of any public offering of EMCORE's common stock, subject to a minimum
offering size requirement of $40.0 million.
 
     On January 27, 1999 EMCORE borrowed $3.0 million from its Chairman, Thomas
J. Russell. This loan bears interest at 8% per annum. On February 1, 1999,
EMCORE repaid this loan from borrowings under a new loan from First Union
National Bank. On February 1, 1999, EMCORE entered into a $5.0 million short-
term note with First Union that matures in May 1999. This note bears interest at
a rate equal to one-month LIBOR plus three quarters of one percent per annum.
 
                                       37
<PAGE>   39
 
     On April 29, 1999, EMCORE borrowed $2.5 million from its Chairman. The loan
bears interest at prime rate plus 2% per annum. On May 7, 1999, the loan was
repaid from borrowings under EMCORE's $19.0 million short-term note, as
discussed below.
 
     On April 29, 1999, EMCORE entered into a $19.0 million short-term loan
agreement with First Union. This loan agreement represented a consolidation of
the $8.0 million loan agreement dated June 22, 1998 and $5.0 million short-term
loan agreements dated February 1, 1999, and an additional note of $6.0 million.
This new loan agreement is due and payable on October 1, 1999 and bears interest
at a rate equal to one-month LIBOR plus three-quarters of one percent per annum
(5.75% at May 14, 1999). On May 7, 1999, EMCORE used borrowings under this new
loan agreement to repay the $2.5 million short-term note from EMCORE's Chairman.
As of May 14, 1999, EMCORE had borrowed approximately $17.5 million under this
new loan agreement. This new loan agreement is guaranteed by EMCORE's Chairman
and Chief Executive Officer.
 
     EMCORE's planned capital expenditures are expected to total approximately
$26 million during fiscal 1999, including approximately $13.4 million in
expenditures related to investments in our joint ventures. Capital spending in
1999 also is expected to include upgrading manufacturing facilities, continued
investment in analytical and diagnostic research and development equipment,
upgrading and purchasing computer equipment, and the manufacture of TurboDisc
systems for in-house use.
 
     EMCORE believes that its current liquidity, together with available credit,
should be sufficient to meet its cash needs for working capital through July
2000. However, if the available credit facilities, cash generated from
operations and cash on hand are not sufficient to satisfy EMCORE's liquidity
requirements, EMCORE will seek to obtain additional equity or debt financing.
Additional funding may not be available when needed or on terms acceptable to
EMCORE. If EMCORE is required to raise additional financing and if adequate
funds are not available or not available on acceptable terms, the ability to
continue to fund expansion, develop and enhance products and services, or
otherwise respond to competitive pressures will be severely limited. Such a
limitation could have a material adverse effect on EMCORE's business, financial
condition or operations.
 
     Under the agreement signed in January 1999 by EMCORE and General Electric
Lighting, when the GELcore joint venture is funded, EMCORE will issue to General
Electric common stock purchase warrants to purchase 282,010 shares of EMCORE's
common stock at an exercise price of $22.875, which will expire in 2006. The
number of common stock purchase warrants was determined based on the market
price of EMCORE's common stock on March 31, 1999. General Electric will purchase
a $7.8 million subordinated convertible debenture bearing interest at 4.75% per
annum and maturing in 2006. The debenture's interest rate will be subject to
adjustment in the event EMCORE does not complete a public offering by June 30,
1999. The debenture will be convertible into 340,984 shares of common stock at a
conversion price equal to $22.875. Proceeds from the debenture will be used to
fund EMCORE's investment in GELcore.
 
     In January 1999, Rockwell settled litigation which challenged the validity
of certain patents which EMCORE licensed from Rockwell prior to the commencement
of the litigation. As a result of this settlement, EMCORE will be required to
pay
 
                                       38
<PAGE>   40
 
Rockwell a royalty including interest under our license agreement relating to
TurboDisc tools. EMCORE believes it has adequately accrued for these royalties.
In addition, prior to the commencement of the litigation, EMCORE had initiated
discussions with Rockwell to receive additional licenses to permit EMCORE to use
the technology to manufacture and sell wafers and devices. EMCORE may be
required to pay royalties to Rockwell for certain past sales of wafers and
devices to customers who do not hold licenses directly from Rockwell. If these
royalties are significant, our business, financial condition and results of
operations may be materially affected. The Rockwell patent expires in January
2000 and we may require additional licenses from Rockwell in order to continue
to manufacture and sell wafers and devices. The failure to obtain licenses to
manufacture these wafers and devices on commercially reasonable terms may
materially and adversely affect our business, financial condition and results of
operations through January 2000.
 
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.  EMCORE 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. EMCORE's assessment plan
consists of
 
          (1) quality assurance testing of its internally developed proprietary
              software;
 
          (2) contacting third-party vendors and licensors of material hardware,
              software and services that are both directly and indirectly
              related to EMCORE's business;
 
          (3) contacting vendors of third-party systems;
 
          (4) assessing repair or replacement requirements;
 
          (5) implementing repair or replacement; and
 
          (6) creating contingency plans in the event of Year 2000 failures.
 
     Our compound semiconductor wafers and devices are date insensitive and,
therefore, do not have any Year 2000 issues associated with them. Our TurboDisc
production systems have several components that could give rise to Year 2000
compliance concerns. We have preliminarily assessed the Year 2000 issues
associated with these components and have found that they have either been
certified by the vendor to be compliant or are date insensitive.
 
     Our principal concern has been the status of our operating, financial and
administrative systems. These systems include accounting and production control
software at our New Jersey, MODE and EmcoreWest facilities. All software has
been certified as Year 2000 compliant by the vendors, except our New Jersey
office's
 
                                       39
<PAGE>   41
 
   
accounting software. However, the software's manufacturer has a new version of
the software that is Year 2000 compliant. We are planning this upgrade. The
upgrade will be installed and tested by June 1999.
    
 
   
     There are other information technology systems and non-information
technology systems that could give rise to Year 2000 concerns. These include
scientific and engineering applications, desktop applications (such as Microsoft
Word and Excel) and facilities controls such as HVAC and security. A review of
these systems leads us to believe that the systems are Year 2000 compliant, are
not critical to business operations, are used on a limited basis or are date
insensitive.
    
 
   
     We are continuing the evaluation of the Year 2000 compliance of all our
systems and have developed an enterprise-wide database that we will use to
document these Year 2000 issues. EMCORE plans to complete its evaluation by
September 30, 1999 including Year 2000 simulation on its systems during the
second and third quarter of calendar 1999 to test systems readiness.
    
 
   
     Costs.  To date, EMCORE has not incurred any material expenditures in
connection with identifying, evaluating or addressing Year 2000 compliance
issues. Most of EMCORE 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.
    
 
   
     The exact costs related to Year 2000 compliance are difficult to determine.
Several known costs relating to our information technology systems are:
    
 
   
     - Updating New Jersey's accounting system, 2 man-weeks or $4,000, and
    
 
   
     - Reviewing software and completing Year 2000 database, 1 man-month or
       $8,000.
    
 
   
     We will be able to make a reasonable determination of the remediation costs
for Year 2000 compliance after we have completed our Year 2000 evaluation. At
present EMCORE believes that the costs for bringing our in-house information
technology systems into compliance should not exceed $200,000.
    
 
   
     EMCORE does not anticipate that remediation expenses will be material. If
the remediation expenses are higher than anticipated EMCORE's business,
financial condition and results of operations could be materially and adversely
affected.
    
 
   
     Risks.  EMCORE is not currently aware of any Year 2000 compliance problems
relating to its systems that would have a material adverse effect on EMCORE's
business, results of operations and financial condition. There can be no
assurance that, upon completion of its evaluation, EMCORE 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 EMCORE's material systems will not need to be revised
or replaced, all of which could be time-consuming and expensive. The failure of
EMCORE 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
EMCORE's business, result of operations and financial condition. Moreover, the
failure to adequately address Year 2000 compliance issues in its internally
    
 
                                       40
<PAGE>   42
 
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, the failure of governmental
agencies, utility companies, third-party service providers and others outside of
EMCORE's control to be Year 2000 compliant could result in systemic failure
beyond EMCORE's control such as a telecommunications or electrical failure,
which could have a material adverse effect on EMCORE's business, results of
operations and financial condition.
 
     Contingency Plan.  As discussed above, EMCORE is engaged in an ongoing Year
2000 assessment and has not yet developed any contingency plans. The results of
EMCORE'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.
EMCORE 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 EMCORE'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-l, "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-l provides guidance over accounting for computer software developed
or obtained for internal use including the requirement to capitalize specified
costs and amortization of such costs. EMCORE does not expect the adoption of
this standard to have a material effect on 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
EMCORE has expensed these costs historically, the adoption of this standard is
not expected to have a significant impact on EMCORE's results of operations,
financial position or cash flows.
 
     In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities." This statement establishes accounting and
reporting standards for derivative instruments and requires recognition of all
derivatives as assets or liabilities in the statement of financial position and
measurement of these instruments at fair value. The statement is effective for
fiscal years beginning after June 15, 1999. Management believes that adopting
this statement will not have a material impact on the financial position,
results of operations, or cash flows of EMCORE.

INDUSTRY OVERVIEW
 
     Recent advances in information technologies have created a growing need for
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 that are generally not achievable using silicon-based
components.
 
     Compound semiconductors have emerged as an enabling technology to meet the
complex requirements of today's advanced information systems. Many compound
semiconductor materials have unique physical properties that allow electrons to
move at least four times faster than through silicon-based devices. Advantages
of compound semiconductor devices over silicon devices include:
 
     - operation at higher speeds;
 
     - lower power consumption;
 
     - less noise and distortion; and
 
     - optoelectronic properties that enable these devices to emit and detect
       light.
 
     Compound semiconductor devices can be used to perform individual functions
as discrete devices, such as solar cells, HB LEDs, VCSELs, MR sensors and RF
materials. Compound semiconductor devices can also be combined into integrated
circuits, such as transmitters, receivers and alpha-numeric displays. Although
compound semiconductors are more expensive to manufacture than silicon-based
devices, electronics manufacturers are increasingly integrating compound
semiconductor devices into their products in order to achieve higher performance
in applications targeted for a wide variety of markets. These include satellite
 
                                       42
<PAGE>   44
 
communications, data communications, telecommunications, wireless
communications, consumer and automotive electronics, computers and peripherals,
and lighting.
 
     The following factors have resulted in an increased demand for compound
semiconductor products and systems that enable electronic systems manufacturers
to reach the market faster with large volumes of high-performance products and
applications:
 
     - rapid build-out of satellite communications systems;
 
     - widespread deployment of fiber optic networks and the increasing use of
       optical systems within these networks;
 
     - launch of new wireless services and wireless high speed data systems;
 
     - increasing use of infrared emitters and optical detectors in computer
       systems;
 
     - emergence of advanced consumer electronics applications, such as DVDs and
       flat panel displays;
 
     - increasing use of high-performance electronic devices in automobiles; and
 
     - the anticipated conversion to HB LEDs from incandescent, halogen and
       compact fluorescent lighting.

COMPOUND SEMICONDUCTOR PROCESS TECHNOLOGY
 
     Compound semiconductors are composed of two or more elements and usually
consist of a metal such as gallium, aluminum or indium and a non-metal such as
arsenic, phosphorous or nitrogen. The resulting compounds include gallium
arsenide, indium phosphide, gallium nitride, indium antimonide and indium
aluminum
 
                                       44
<PAGE>   46
 
phosphide. The performance characteristics of compound semiconductors are
dependent on the composition of these compounds. Many of the unique properties
of compound semiconductor devices are achieved by the layering of different
compound semiconductor materials in the same device. This layered structure
creates an optimal configuration to permit the conversion of electricity into
light.
 
     Accordingly, the composition and properties of each layer and the control
of the layering process, or epitaxy, are fundamental to the performance of
advanced electronic and optoelectronic compound semiconductor devices. The
variation of thickness and composition of layers determines the intensity and
color of the light emitted or detected and the efficiency of power conversion.
The ability to vary the intensity, color and efficiency of light generation and
detection enables compound semiconductor devices to be used in a broad range of
advanced information systems.
 
     Compound semiconductor device manufacturers predominantly use four methods
to deposit compound materials: molecular beam epitaxy, vapor phase epitaxy,
liquid phase epitaxy and metal organic chemical vapor deposition (MOCVD). The
use of molecular beam epitaxy technology can yield wafers having high thickness
uniformity. Compound semiconductor materials fabricated using liquid phase
epitaxy or vapor phase epitaxy technologies often have high electronic and
optical properties. However, due to the nature of the underlying processes,
these methods are not easily scaled up to high volume production, which is
necessary for the commercial viability of compound semiconductor devices. All of
the methods used to manufacture compound semiconductor devices pose technical,
training and safety challenges that are not present in the manufacture of
silicon devices. These production systems typically require expensive reactant
materials, the use of certain toxic chemicals, and tight control over numerous
manufacturing parameters. The key differences between MOCVD and the three other
methods is that compound semiconductor wafers fabricated using MOCVD generally
possess a better combination of uniformity and optical and electronic properties
and are easier to produce in high volumes than wafers manufactured by the three
more traditional methods. Currently, MOCVD technology is being used to
manufacture a broad range of compound semiconductor devices.
 
     Historically, manufacturers who use compound semiconductor devices in their
products have met research, pilot production and capacity needs with in-house
systems and technologies. However, as the need for the production of commercial
volumes of high-performance compound semiconductor devices and the variety of
these devices grows, manufacturers are often unable to meet these requirements
using in-house solutions. In response to these growing demands for higher
volumes of a broad range of higher performance devices, manufacturers are
increasingly turning to outside vendors to meet their needs for compound
semiconductor wafers and devices.
 
THE EMCORE SOLUTION
 
     EMCORE provides its customers with a broad range of compound semiconductor
products and services intended to meet its customers' diverse technology
requirements. EMCORE has developed extensive materials science expertise,
process technology and MOCVD production systems to address these needs and
believes that its proprietary TurboDisc deposition technology makes possible one
of the most cost-effective production processes for the commercial volume
manufacture of high-performance compound semiconductor wafers and devices. This
platform technology provides the
 
                                       45
<PAGE>   47
 
basis for the production of various types of compound semiconductor wafers and
devices and enables EMCORE to address the critical need of manufacturers to
cost-effectively get to market faster with high volumes of new and improved
high-performance products. EMCORE's compound semiconductor products and services
include:
 
     - materials and process development;
 
     - design and development of devices;
 
     - MOCVD production systems; and
 
     - manufacture of wafers and devices in high volumes.
 
     Customers can take advantage of EMCORE's vertically integrated approach by
purchasing custom-designed wafers and devices from EMCORE or manufacturing their
own devices in-house using a TurboDisc production system configured to their
specific needs.
 
STRATEGY
 
     EMCORE's objective is to capitalize on its position in MOCVD process
technology and production systems to become the leading supplier of compound
semiconductor wafers, devices and production systems. The key elements of
EMCORE's strategy include:
 
     Apply Core Technology Across Multiple Applications.  EMCORE continually
leverages its proprietary core technology to develop compound semiconductor
products for multiple applications in a variety of markets. These activities
include developing new products for targeted applications as well as expanding
existing products into new applications. For example, EMCORE's MR sensors,
currently used by General Motors as crank shaft sensors, also have other
potential product applications, including as sensors in brushless motors and
antilock brakes. Other existing products which EMCORE intends to introduce in
new applications include VCSELs for communications products and HB LEDs for
broader lighting applications.
 
     Target High Growth Opportunities.  EMCORE's strategy is to target high
growth opportunities where performance characteristics and high volume
production efficiencies can give compound semiconductors a competitive advantage
over other devices. Historically, while technologically superior, compound
semiconductors have not been widely deployed because they are more expensive to
manufacture than silicon-based semiconductors and other existing solutions.
EMCORE believes that as compound semiconductor production costs are reduced, new
customers will be compelled to use these solutions because of their higher
performance characteristics. For example, EMCORE has reduced the average cost of
compound semiconductor solar cells to the point that they are replacing
silicon-based solar cells because of the compound semiconductor solar cells'
higher overall efficiency and lower weight.
 
     Partner with Key Industry Participants.  EMCORE seeks to identify and
develop long-term relationships with leading companies in targeted industries.
EMCORE develops these relationships in a number of ways including through
long-term high-volume supply agreements, joint ventures, and distribution and
other arrangements. For example, EMCORE has agreed to enter into, subject to
certain conditions, a joint
 
                                       46
<PAGE>   48
 
venture with General Electric Lighting for the development and marketing of
white light and colored HB LED products for automotive, traffic, flat panel
display and other lighting applications, and has entered into a long term supply
agreement with AMP Incorporated for VCSELs to be used in its transceivers for
Gigabit Ethernet and other applications. EMCORE intends to actively seek similar
strategic relationships with other key customers and industry participants in
order to further expand its technological and production base.
 
     Continue Investment to Maintain Technology Leadership.  Through substantial
investment in research and development, EMCORE seeks to expand its leadership
position in compound semiconductor production systems, wafers and devices.
EMCORE works with its customers to identify specific performance criteria and
uses this information 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 devices for its customers.
In addition, EMCORE's development efforts are focused on continually lowering
the production costs of its solutions. EMCORE's joint venture with Union Miniere
Inc. represents an initiative to explore means to use germanium to improve
product performance, identify new product applications and lower the cost and
complexity of production of EMCORE's wafers and devices.
 
PRODUCTS
 
PRODUCTION SYSTEMS
 
     EMCORE is a leading supplier of MOCVD compound semiconductor production
systems, with more than 230 systems shipped as of March 31, 1999. According to
VLSI Research, Inc., in 1997 EMCORE's share of the MOCVD production systems
market was over 25%. EMCORE believes that its TurboDisc systems offer
significant ownership advantages over competing systems and that the high
throughput capabilities of its TurboDisc systems make possible superior
reproducibility of thickness, composition, electronic properties and layer
accuracy required for electronic and optoelectronic devices. Each system can be
customized for the customer's throughput, wafer size and process chemistry
requirements. EMCORE's production systems also achieve a high degree of
reliability with an average time available for production, based on customer
data, of approximately 95%.
 
     EMCORE believes its TurboDisc systems enable the lowest cost of ownership
for the manufacture of compound semiconductor materials. The major components of
the cost of ownership include yield, throughput, direct costs and capital costs.
Yield primarily relates to material uniformity, which is a function of the
precision of the physical and chemical processes by which atomic layers are
deposited. Throughput, the volume of wafers produced per unit of time, includes
both the time required for a process cycle and the handling time between process
steps. Direct costs include consumables used in manufacturing and processing and
the clean room space required for the equipment. Capital costs include the cost
of acquisition and installation of the process equipment.
 
     EMCORE's proprietary TurboDisc technology utilizes a unique high speed
rotating disk in a stainless steel growth chamber with integrated
vacuum-compatible loading chambers. To produce a wafer, a bare substrate, such
as gallium arsenide,
 
                                       47
<PAGE>   49
 
sapphire or germanium, is placed on a wafer carrier in the TurboDisc growth
chamber and subjected to high temperatures. Based on a predetermined formula,
metal organic gases are released into the growth chamber. These gases decompose
on the hot, rapidly spinning wafer. Semiconductor materials are then deposited
on the substrate in a highly uniform manner. The resulting wafer thus carries
one or more ultra-thin layers of compound semiconductor material such as gallium
arsenide, gallium nitride, or indium aluminum phosphide. The TurboDisc
technology not only produces uniformity of deposition across the wafer, but also
offers flexibility for diverse applications with improved material results and
increased production rates. The unique precision control of reactant gas flow in
the TurboDisc technology platform allows users to scale easily from research to
commercial volumes with substantially reduced time and effort. Upon removal from
the growth chamber, the wafer is transferred to a device processing facility for
various steps such as photolithography, etching, masking, metallization and
dicing. Upon completion of these steps, the devices are then sent for packaging
by the customer or other third parties and inclusion in the customer's product.

                              (Turbodisc Diagram)
 
     Wafers are loaded on a multiple wafer platter into the growth chamber,
where they are subjected to high-temperature vacuum conditions and spun at high
speeds. Gases are then introduced into the vacuum growth chamber, and
semiconductor materials become deposited onto the substrate in a highly uniform
manner.
 
     EMCORE offers the following family of TurboDisc systems:

     Solar Cells.  Compound semiconductor solar cells are used to power
satellites because they are more resistant to radiation levels in space, convert
substantially more light to power and therefore weigh less per unit of power
than silicon-based solar cells. These characteristics increase satellite life,
increase payload capacity and reduce launch costs. EMCORE is currently involved
in four solar cell projects:
 
     - In November 1998, EMCORE signed a four-year purchase agreement with Space
       Systems/Loral, a wholly owned subsidiary of Loral Space & Communications.
       Under this agreement, which is contingent upon our compliance with
       Loral's product specification requirements, EMCORE will supply compound
       semiconductor high efficiency gallium arsenide solar cells for Loral's
       satellites. EMCORE anticipates completing this qualification in June
       1999. Subject to satisfactorily completing these product qualification
       requirements, EMCORE has received an initial purchase order from Space
       Systems/Loral.
 
     - In August 1998, EMCORE and Union Miniere Inc., a mining and materials
       company, entered into a long term supply agreement for germanium, which
       EMCORE uses to fabricate solar cells. In addition to their solar cell
       relationship, in November 1998, EMCORE formed UMCore, a joint venture
       with Union Miniere to explore and develop alternate uses for germanium
       using EMCORE's material science and production platform expertise and
       Union Miniere's access to and experience with germanium. UMCore commenced
       research and development operations in January 1999.
 
     - In September 1998, EMCORE entered into an agreement with Lockheed Martin
       Missiles and Space, a strategic business unit of Lockheed Martin
       Corporation, to provide technical management and support of a Cooperative
       Research and Development Agreement between Lockheed Martin and Sandia
       National Laboratory for the advancement and commercialization of a new
       compound semiconductor high efficiency solar cell. Pursuant to this
       strategic agreement, (1) Lockheed Martin will grant EMCORE a sub-license
       for all related intellectual property developed on behalf of or in
       conjunction with Lockheed Martin, and (2) EMCORE and Lockheed Martin will
       jointly qualify and validate the high efficiency solar cells for
       operational satellite use.
 
     - In the summer of 1998, EMCORE received a $2.2 million contract under the
       U.S. Air Force's Broad Agency Announcement Program for the development of
       high-efficiency advanced solar cells.
 
     HB LEDs.  High-brightness light-emitting diodes (HB LEDs) are solid state
compound semiconductor devices that emit light. The global demand for HB LEDs is
experiencing rapid growth because LEDs have a long useful life (approximately 10
years), consume approximately 10% of the power consumed by incandescent or
halogen lighting and improve display visibility. In February 1998, EMCORE and
Uniroyal Technology Corporation formed Uniroyal Optoelectronics, a joint venture
to manufacture, sell and distribute HB LED wafers and package-ready devices.
 
     In January 1999, EMCORE signed an agreement with General Electric Lighting
to form GELcore, a joint venture to develop and market HB LED lighting products.
General Electric Lighting and EMCORE have agreed that this joint venture will be
the exclusive vehicle for each party's participation in solid state lighting.
GELcore seeks to combine EMCORE's materials science expertise, process
technology and
 
                                       51
<PAGE>   53
 
compound semiconductor production systems with General Electric Lighting's brand
name recognition and extensive marketing and distribution capabilities.
GELcore's long-term goal is to develop products to replace traditional lighting.
 
     VCSELs.  VCSELs are semiconductor lasers that emit light in a cylindrical
beam. Leading electronic systems manufacturers are integrating VCSELs into a
broad array of end-market applications including Internet access, digital
cross-connect telecommunications switches, DVD, and fiber optic switching and
routing, such as Gigabit Ethernet. VCSELs offer significant advantages over
traditional laser diodes, including:
 
     - greater control over beam size and wavelength;
 
     - reduced manufacturing complexity and packaging costs;
 
     - lower power consumption; and
 
     - higher frequency performance.
 
     In December 1997, EMCORE acquired MODE, a development stage company,
primarily dedicated to the research and development of enabling VCSEL
technologies. In February 1998, EMCORE announced Gigalase, its first commercial
high speed VCSEL laser. In September 1998, EMCORE signed a four-year purchase
agreement with AMP Incorporated to provide VCSELs for a family of optical
transceivers for the Gigabit Ethernet, FibreChannel and ATM markets. In December
1998, EMCORE announced its second VCSEL product, Gigarray, a micro-optical laser
array.
 
     MR Sensors.  MR sensors are compound semiconductor devices that possess
sensing capabilities. MR sensors improve vehicle performance through more
accurate control of engine and crank shaft timing, which allows for improved
spark plug efficiency and reduced emissions. In January 1997, EMCORE initiated
shipments of compound semiconductor MR sensors using technology licensed to
EMCORE from General Motors. This license allows EMCORE to manufacture and sell
products using this technology to anyone. As of March 31, 1999 EMCORE has
delivered over five million devices to General Motors Powertrain for crank and
cam speed and position sensing applications for three engine builds.
 
     In October 1998, EMCORE formed Emtech, a joint venture with Optek
Technology, Inc., a packager and distributor of optoelectronic devices, to
market an expanded line of MR sensors to the automotive and related industries.
This joint venture seeks to combine EMCORE's strength in producing devices with
Optek's strength in packaging and distributing devices to offer off-the-shelf
products and expand market penetration.
 
     RF materials.  Radio frequency materials are compound semiconductor
materials which transmit and receive communications. Compound semiconductor RF
materials have a broader bandwidth and superior performance at high frequencies
than silicon-based materials. EMCORE currently produces RF materials for use as
power amplifiers in cellular phone handsets. In addition, EMCORE is exploring
opportunities to market these materials for additional uses in fiber optics and
satellite communications. EMCORE believes that its ability to produce high
volumes of RF materials at a low cost will facilitate their adoption in new
applications and new products.
 
                                       52
<PAGE>   54
 
     In May 1999, Sumitomo Electric and EMCORE announced a long-term agreement
to jointly develop and produce certain RF materials for use in digital wireless
and cellular applications. EMCORE will manufacture these RF materials at our
Somerset, New Jersey manufacturing facility and Sumitomo Electric will market
them in Japan. Sumitomo Electric is one of the world's leading electronics
manufacturers. Shipments of these devices are expected to begin in June 1999.
 
CUSTOMERS
 
     EMCORE's customers include many of the largest semiconductor,
telecommunications, consumer goods and computer manufacturing companies in the
world. Sales to Hughes-Spectrolab accounted for 17.3% of EMCORE's revenues in
fiscal 1998 and 3.8% of EMCORE's revenues in the first six months of 1999. Sales
to General Motors accounted for 12.8% of EMCORE's revenues in fiscal 1998 and
10.8% of EMCORE's revenues in the first six months of 1999. A number of EMCORE's
customers are listed below. In addition, EMCORE has sold its products to 12 of
the largest electronics manufacturers in Japan.

     EMCORE has a comprehensive total quality management program with special
emphasis on total customer satisfaction. EMCORE seeks to encourage active
customer involvement with the design and operation of its production systems. To
accomplish this, EMCORE conducts user group meetings among its customers in
Asia, Europe and North America. At annual meetings, EMCORE's customers provide
valuable feedback on key operations, process oriented services, problems and
recommendations to improve EMCORE products. This direct customer feedback has
enabled EMCORE to constantly update and improve the design of its systems and
processes. Changes that affect the reliability and capabilities of EMCORE's
systems are embodied in new designs to enable current and future customers to
utilize systems which EMCORE believes are high quality and cost-efficient. As of
March 31, 1999, EMCORE employed 27 field service engineers who install EMCORE
systems and provide on-site support.
 
MARKETING AND SALES
 
     EMCORE markets and sells its wafers, devices and systems through its direct
sales force in Europe, North America and Taiwan and through representatives and
distributors elsewhere in Asia. To market and service its products in China,
Japan and Singapore, EMCORE relies on a single marketing, distribution and
service provider, Hakuto. EMCORE's agreements with Hakuto have a term of 10
years, expiring March 2008. Hakuto has exclusive distribution rights for certain
of EMCORE's products in Japan. Hakuto has marketed and serviced EMCORE's
products since 1988, is a minority shareholder in EMCORE, and the President of
Hakuto is a member of EMCORE's board of directors. EMCORE recently opened sales
offices in
 
                                       53
<PAGE>   55
 
Taiwan and California in order to be closer to its customers. As of March 31,
1999, EMCORE employed 26 persons in sales and marketing.
 
     EMCORE's sales and marketing staff, senior management and technical staff
work closely with existing and potential customers to provide compound
semiconductor solutions for its customers' needs. The sales process begins by
understanding the customer's requirements and then attempting to match these
requirements with the optimal solution. EMCORE seeks to match the customer's
requirements to an existing design or a modification of a standard design, such
as a change in platform or process design. When necessary, EMCORE will work with
the customer to develop the appropriate design process and to configure and
manufacture the production system to meet the customer's needs. Also, EMCORE
will produce samples to demonstrate conformance to the customer's
specifications. For production systems, the amount of time from the initial
contact with the customer to the customer's placement of an order is typically
two to nine months or longer. EMCORE's sales cycle for wafers and devices
usually runs three to nine months, during which time EMCORE develops the formula
of materials necessary to meet the customer's specifications and qualifies the
materials, which may also require the delivery of samples. EMCORE believes that
the high level of marketing, management and engineering support involved in this
process is beneficial in developing competitive differentiation and long-term
relationships with its customers.
 
     The following chart contains a breakdown of EMCORE's worldwide revenues and
percentages by geographic region. Historically, EMCORE has received all payments
for products and services in U.S. dollars.

SERVICE AND SUPPORT
 
     EMCORE maintains a worldwide 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 EMCORE is required to maintain an inventory of replacement parts and to
service the equipment upon the request of the customer. EMCORE also sells
replacement parts from inventory for customer needs. EMCORE pursues a program of
system upgrades for customers to increase the performance of older systems.
EMCORE generally does not offer extended payment terms to its customers and
generally adheres to a warranty policy of one year. Consistent with industry
practice, EMCORE 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. EMCORE recently opened a warehouse
depot in Taiwan to provide improved service to its Asian customers.

RESEARCH AND DEVELOPMENT
 
     To maintain and improve its competitive position, EMCORE's research and
development efforts are focused on designing new proprietary processes and
products, improving the performance of existing systems, wafers and devices and
reducing costs in the product manufacturing process. EMCORE has dedicated 16
TurboDisc 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. EMCORE's recurring research and development
expenses were approximately $10.3 million in the first six months of fiscal
1999, $16.5 million in fiscal 1998, $9.0 million in fiscal 1997 and $5.4 million
in fiscal 1996. EMCORE also incurred a one-time, non-cash research and
development expense in fiscal 1998 in the amount of $19.5 million in connection
with the acquisition of MODE. EMCORE expects that it will continue to expend
substantial resources on research and development. As of March 31, 1999, EMCORE
employed 50 persons in research and development, 14 of whom held Ph.D.s in
materials science or related fields.
 
     EMCORE also competes for research and development funds. In view of the
high cost of development, EMCORE solicits research contracts that provide
opportunities to enhance its core technology base or promote the
commercialization of targeted products. EMCORE presently has three contracts
under the Small Business Innovative Research programs or similar government
sponsored programs. From inception until March 31, 1999, government and other
external research contracts have provided approximately $13.3 million to support
EMCORE's research and development efforts. EMCORE 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
 
     EMCORE's success and competitive position both for production systems and
wafers and devices depend significantly on its ability to maintain trade secrets
and other intellectual property protections. Our strategy is to rely more on
trade secrets than patents. 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.
Reliance on trade secrets is only an effective business practice insofar as
trade secrets remain undisclosed and a proprietary product or process is not
reverse engineered or independently developed. In order to protect its trade
secrets, EMCORE takes certain measures to ensure their secrecy, such as
executing non-disclosure agreements with its employees, joint venture partners,
customers and suppliers.
 
     To date, EMCORE has been issued 11 U.S. patents and others 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 EMCORE's systems, wafers or devices. EMCORE relies on
trade secrets rather than patents to protect its intellectual property because
it believes publishing patents would make it easier for others to reverse
engineer EMCORE's proprietary processes.
 
                                       55

     EMCORE is a licensee of certain VCSEL technology and associated patent
rights owned by Sandia Corporation. The Sandia license grants EMCORE:
     - exclusive rights (subject to certain rights granted to Department of
       Energy and AT&T Corporation) to develop, manufacture and sell products
       containing Sandia VCSEL technologies for barcode scanning and plastic
       optical fiber communications applications under five U.S. patents that
       expire between 2007 and 2015;
     - nonexclusive rights with respect to all other applications of these
       patents; and
     - nonexclusive rights to employ a proprietary oxidation fabrication method
       in the manufacture of VCSEL products under a sixth U.S. patent that
       expires in 2014. Our exclusivity with respect to the barcode scanning and
       plastic optical fiber communications applications expires in 2003 or such
       earlier time as we fail to meet certain development and marketing
       criteria. EMCORE'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.
 
     In 1992, we received a royalty-bearing, non-exclusive license under a
patent held by Rockwell International Corporation which relates to an aspect of
the manufacturing process used by our TurboDisc systems. In October 1996, we
initiated discussions with Rockwell to receive additional licenses to permit us
to use this technology to manufacture and sell compound semiconductor wafers and
devices. In November 1996, we suspended these negotiations because of litigation
surrounding the validity of the Rockwell patent. We also ceased making royalty
payments to Rockwell under the license during the pendency of the litigation. In
January 1999, the case was settled and a judgment was entered in favor of
Rockwell. As a result, we may be required to pay royalties to Rockwell for
certain of our past sales of wafers and devices to our customers who did not
hold licenses directly from Rockwell. If we are required to pay significant
royalties in connection with these sales our business, financial condition and
results of operations may be materially and adversely affected. In addition,
until the patent expires in January 2000, we may require additional licenses
from Rockwell under the Rockwell patent in order to continue to manufacture and
sell wafers and devices. The failure to obtain or maintain licenses to
manufacture these wafers and devices on commercially reasonable terms may
materially and adversely affect our business, financial condition and results of
operations.
 
ENVIRONMENTAL REGULATIONS
 
     EMCORE 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 production of
wafers and devices involves the use of certain hazardous raw materials,
including, but not limited to, ammonia, phosphine and arsene. If EMCORE's
control systems are unsuccessful in preventing release of these or other
hazardous materials, EMCORE could experience a substantial interruption of
operations. EMCORE has retained an environmental consultant to advise it in
complying with applicable environmental and health and safety laws and
 
                                       56
<PAGE>   58
 
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 March 31, 1999, EMCORE had an order backlog of $38.3 million,
scheduled to be shipped through March 31, 2000. This represented an increase of
69% since September 30, 1998. This increase primarily relates to increased
production systems bookings in Asia and an initial order for solar cells from
Loral, which is subject to product qualification. EMCORE includes in backlog
only customer purchase orders that have been accepted by EMCORE and for which
shipment dates have been assigned within the 12 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. EMCORE receives partial advance payments or irrevocable letters of
credit on most production system orders. EMCORE recognizes revenue from the sale
of its systems and materials upon shipment. For research contracts with the U.S.
government and commercial enterprises with durations greater than six months,
EMCORE recognizes revenue to the extent of costs incurred plus a portion of
estimated gross profit, as stipulated in such contracts, based on contract
performance.
 
MANUFACTURING
 
     EMCORE's manufacturing operations are located at EMCORE'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 EMCORE's manufacturing operations are computer monitored or
controlled to enhance reliability and yield. EMCORE manufactures its own systems
and outsources some components and sub-assemblies, but performs all final system
integration, assembly and testing. As of March 31, 1998, EMCORE had 158
employees involved in manufacturing. EMCORE 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. EMCORE's
joint venture with Uniroyal Technology Corporation expects to begin
manufacturing HB LED wafers and package-ready devices at its Tampa, Florida
manufacturing facility by summer of 1999. In May 1998, EMCORE received ISO 9001
and QS 9002 quality certification for its Somerset, New Jersey facility. EMCORE
is pursuing ISO 9001 quality certification for its Albuquerque, New Mexico
facilities.
 
     Outside contractors and suppliers are used to supply raw materials and
standard components and to assemble portions of end systems from EMCORE
specifications. EMCORE depends on sole, or a limited number of, suppliers of
components and raw materials. EMCORE generally purchases these single or limited
source products through standard purchase orders. EMCORE 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. EMCORE implemented a vendor program through which it inspects
quality and reviews suppliers 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 and adversely affected
by a stoppage or delay of supply, receipt of defective
 
                                       57
<PAGE>   59
 
parts or contaminated materials, and increase in the pricing of such parts or
EMCORE's inability to obtain reduced pricing from its suppliers in response to
competitive pressures.
 
COMPETITION
 
     The markets in which EMCORE competes are highly competitive. EMCORE
competes with several companies for sales of MOCVD systems including Aixtron
GmbH, Nippon-Sanso K.K. and Thomas Swann Ltd. The primary competitors for
EMCORE's wafer foundry include Epitaxial Products Inc., Kopin Corporation and
Quantum Epitaxial Designs, Inc. EMCORE's principal competitors for sales of
VCSEL-related products include Honeywell, Inc. and Mitel Corporation. The
principal competitors for MR sensors are Honeywell, Inc., Matshushita Electric
Industrial Co. Ltd., Siemens AG and Asahi. The principal competitors for HB LEDs
and EMCORE's joint venture with Uniroyal Technology Corporation and the pending
joint venture with General Electric Lighting include the Phillips Electronics
and Hewlett Packard Company joint venture, Siemens AG's Osram GmbH subsidiary,
Nichia Chemical Industries and Toshiba Corporation. EMCORE also faces
competition from manufacturers that implement in-house systems for their own
use. In addition, EMCORE competes with many research institutions and
universities for research contract funding. EMCORE also sells its products to
current competitors and companies with the capability of becoming competitors.
As the markets for EMCORE's products grow, new competitors are likely to emerge,
and present competitors may increase their market share.
 
     EMCORE believes that the primary competitive factors in the markets in
which EMCORE's products compete are yield, throughput, performance, breadth of
product line, customer satisfaction, customer commitment to competing
technologies and, in the case of production systems, capital and directs costs
and size of installed base. Competitors may develop enhancements to or future
generations of competitive products that offer superior price and performance
factors. EMCORE 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 March 31, 1999, EMCORE had 326 full-time employees. None of EMCORE's
employees is covered by a collective bargaining agreement. EMCORE considers its
relationship with its employees to be good.

                 CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS
 
     On April 29, 1999, EMCORE borrowed $2.5 million from its Chairman at an
interest rate of prime plus two percent. On May 7, 1999, EMCORE repaid the loan
from borrowings from First Union.
 
     In January 1999, EMCORE's Chairman advanced $3.0 million to EMCORE. These
funds were repaid with borrowings under a new $5.0 million credit facility with
First Union National Bank. The Chairman has also committed to provide up to
$30.0 million of long-term financing to EMCORE through July 1, 2000. This
commitment terminates upon completion of this offering, subject to a minimum
offering size requirement of $40.0 million.
 
     In January 1999, EMCORE and General Electric Lighting agreed, subject to
certain conditions, to form a joint venture to develop and market HB LED
lighting products. In connection with consummation of this joint venture, EMCORE
will issue to General Electric warrants to purchase 282,010 shares of EMCORE
common stock, which will expire in 2006, have an exercise price of $22.875. In
addition, General Electric will purchase a $7.8 million subordinated convertible
debenture bearing interest at 4.75% per annum and maturing in 2006. The
debenture will be convertible into 340,984 shares of common stock at General
Electric's option.
 
     On November 30, 1998, EMCORE completed a private placement of an aggregate
of 1,550,000 shares of Series I Preferred Stock to Hakuto, Union Miniere Inc.
and Uniroyal Technology Corporation. The net proceeds to EMCORE from the private
placement were approximately $21.2 million which has been used (1) to repay $8.5
million of debt, plus interest, to EMCORE's Chairman of the Board, Dr. Thomas
Russell, (2) to fund EMCORE's $5.0 million portion of a joint venture between
EMCORE and Uniroyal Technology Corporation to develop and manufacture HB LEDs
and (3) to fund EMCORE's $600,000 portion of its joint venture with Union
Miniere Inc. The remaining net proceeds from the private placement of
convertible preferred stock were used to acquire capital equipment for EMCORE's
new Albuquerque, New Mexico manufacturing facility and for working capital
purposes.
 
     In September and October 1998, EMCORE borrowed an aggregate of $8.5 million
from its Chairman, Thomas J. Russell. The loan bears interest at 9.75% per
annum. The entire $8.5 million borrowed from Mr. Russell was repaid from the
proceeds of the private placement of preferred stock.
 
     On June 22, 1998, EMCORE entered into the 1998 Agreement with First Union
National Bank. The 1998 Agreement was guaranteed by the Chairman and the Chief
Executive Officer of EMCORE. In return for guaranteeing the facility, EMCORE
granted the Chairman and the Chief Executive Officer an aggregate of 284,684
common stock purchase warrants at an exercise price of $11.375 per share which
expire May 1, 2001. These warrants are callable at EMCORE's option at $0.85 per
warrant if EMCORE's common stock has traded at or above 150% of the exercise
price for a period of 30 days. The warrant exercise price was equal to the
market price of the Company's common stock on the date of grant. An accounting
value of $1.3 million was assigned to these warrants based upon the EMCORE's
application of the Black-Scholes option pricing model.

     The President of Hakuto Co., Ltd., EMCORE's Asian distributor, is a member
of EMCORE's board of directors and Hakuto Co., Ltd. is a minority shareholder of
EMCORE. During the year ended September 30, 1998, sales made through Hakuto Co.,
Ltd. approximated $9.2 million.
 
     In February 1998, EMCORE and Uniroyal Technology Corporation formed
Uniroyal Optoelectronics, a joint venture to produce and market compound
semiconductor products. EMCORE has a non-controlling minority interest in the
joint venture. During the first six months of fiscal 1999, EMCORE sold three
TurboDisc systems to the joint venture for a total of $5.3 million. As of March
31, 1999, EMCORE's investment in this venture amounted to $4.3 million.
 
     In fiscal 1997, EMCORE signed a non-exclusive and non-refundable technology
licensing and royalty agreement with Uniroyal Technology Corporation for the
process technology to develop and manufacture HB LEDs. During fiscal 1998 and
1997, revenue associated with the Uniroyal Technology Corporation licensing
agreement amounted to $2.5 million and $2.5 million, respectively. At the time
the transaction was originally entered into, Uniroyal Technology Corporation's
Chairman and Chief Executive Officer was a member of EMCORE's board of directors
and EMCORE's Chairman was on the Board of Directors of Uniroyal Technology
Corporation.
 
     All related party transactions were approved by a majority of the
disinterested members of EMCORE's board of directors.

explanatory paragraph relating to a restatement described in Note 20), which is
included and incorporated by reference herein, and has been so included and
incorporated in reliance upon the report of such firm given upon their authority
as experts in accounting and auditing.
 
     The balance sheet as of September 30, 1997, and the statements of
operations, shareholders' equity and cash flow for the two year period ended
September 30, 1997, included in this prospectus, have been included herein in
reliance on the report of PricewaterhouseCoopers LLP, independent accountants,

the authority of said firm as experts in giving said reports. EMCORE has agreed
to indemnify and hold harmless Arthur Andersen LLP and its personnel for any
costs and expenses including attorneys' fees incurred by Arthur Andersen in
successful defense of a legal action or proceeding that arises as a result of
Arthur Andersen's consent to the inclusion of its audit reports on MODE's past
financial statements in a registration statement filed by EMCORE with the SEC. A
successful defense in this context would be one in which Arthur Andersen is
neither decreed to have been culpable nor pays any part of MODE's or EMCORE's
damages as a result of judgment or settlement.

           PRO FORMA CONSOLIDATED STATEMENT OF OPERATIONS (UNAUDITED)
 
     On December 5, 1997, EMCORE acquired all of the outstanding capital stock
of MODE in exchange for 1,461,866 shares of EMCORE's common stock, 200,966
common stock purchase options and 47,118 common stock purchase warrants. The
purchase price was approximately $32.8 million, including direct acquisition
costs of approximately $500,000. MODE was a development stage company
(incorporated in August 1995) and had 18 employees at the date of acquisition.
MODE's activities were substantially directed towards the research and
development of optical laser devices. The following unaudited pro forma
consolidated statement of operations is based on the historical financial
statements of EMCORE and MODE, adjusted to give the effect to the acquisition of
MODE by EMCORE. The unaudited pro forma consolidated statements of operations
assume that the acquisition of MODE by EMCORE occurred as of October 1, 1997.
The pro forma financial information reflects the purchase method of accounting
for the acquisition of MODE. The accompanying unaudited pro forma information
does not give effect to any cost savings that may be realized as a result of the
integration of EMCORE and MODE, or to any changes in the revenues of the
combined entity, resulting from such integration. The accompanying unaudited pro
forma financial information should be read in conjunction with EMCORE's
historical financial statements and the notes thereto and the MODE historical
financial statements and the notes thereto included herein. Such unaudited pro
forma financial information does not purport to be indicative of the results of
operations of EMCORE in the future or what its financial position and results of
operations would have been had the acquisition occurred at the dates indicated
above.
 
     EMCORE's acquisition of MODE, a development stage company, constituted a
significant and strategic investment for EMCORE to acquire and gain access to
MODE's in-process research and development of micro-optical technology. EMCORE's
over-riding investment consideration was that if MODE's research and development
efforts, with continued research and development funding contemplated and
required after acquisition, yielded commercial products for targeted
applications, EMCORE would possess a broader array of enabling advanced
technologies and would be better positioned for entry into certain existing
large and/or high growth technology-dependent markets. The primary value
enhancing asset acquired in the MODE acquisition was the technology under
development by MODE as part of its planned micro-laser and optical subassembly
products. EMCORE plans to use MODE's micro-optical laser technology in new
products for data communications and telecommunications applications. As of the
date of acquisition, MODE had six primary micro-optical laser research and
development projects in process. EMCORE expects MODE's microlasers and optical
subassemblies to provide design, performance and significant cost advantages
over their technical predecessors such as edge-emitting solid state lasers.
Through the integration of vertical cavity surface emitting lasers (VCSELs) with
leading original equipment manufacturer 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, digital video discs (DVDs) and fiberoptic switching. In developing
EMCORE's financial projections for future revenues and costs, new micro-optical
laser product introductions were expected to commence in fiscal 1998 and
reflected the
 
                                       71
<PAGE>   73
 
impact of entering new markets such as the data communications and
telecommunications industries. Should EMCORE be unable to complete the
development of any of the six projects, EMCORE may not realize the product,
market and financial benefits expected from this acquisition. In February 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.
 
     As part of the acquisition, EMCORE incurred a one-time in-process research
and development write-off of $19.5 million which is reflected in the
accompanying financial statements. EMCORE also recorded goodwill of
approximately $13.2 million. This is being charged against operations over a
three year period, and will therefore impact financial results through December
2000.

Notes to Pro Forma Statement of Operations
 
(1) EMCORE acquired MODE on December 5, 1997 in exchange for (i) the issuance of
    1,461,866 shares of common stock, and (ii) the assumption of (x) up to
    200,966 common stock purchase options at exercise prices ranging from $0.43
    to $0.59 and (y) 47,118 common stock purchase warrants at exercise prices
    ranging from $4.32 to $5.92. The transaction purchase price amounted to
    approximately $32,800,000, including approximately $500,000 of direct
    acquisition costs. EMCORE's
 
                                       72
<PAGE>   74
 
    common stock was valued based upon the average closing price of EMCORE's
    common stock for the five days before and after the announcement of the
    acquisition. The purchase price was allocated to the assets acquired
    (approximately $2,801,000) and liabilities assumed (approximately
    $2,645,000), based upon the fair value at the date of acquisition. In
    addition, EMCORE recorded a one-time write-off of approximately $19,516,000
    (as restated) relating to purchased in-process research and development.
    Goodwill of approximately $13,157,000 (as restated) was recorded as a result
    of the acquisition.
 
(2) To reflect the amortization of goodwill over a period of three years.
 
(3) To reverse the non-recurring, one-time write-off of $19,516,000 (as
    restated) relating to purchased in-process research and development.
 
(4) The operating results of MODE are from the period of October 1, 1997 through
    the date of acquisition. Subsequent to the date of acquisition, MODE's
    operations are included with those of EMCORE.
 
The pro forma statement of operations for the year ended September 30, 1998,
does not reflect the non-recurring write-off of the acquired in-process research
and development.

                          INDEPENDENT AUDITORS' REPORT
 
To the Board of Directors and
Shareholders of EMCORE Corporation
Somerset, New Jersey
 
     We have audited the accompanying consolidated balance sheet of EMCORE
Corporation, (the "Company") as of September 30, 1998, and the related
consolidated statements of operations, shareholders' equity, and cash flows for
the year then ended. These financial statements are the responsibility of the
Company's management. Our responsibility is to express an opinion on the
financial statements based on our audit.
 
     We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.
 
     In our opinion, the 1998 consolidated financial statements present fairly,
in all material respects, the financial position of the Company as of September
30, 1998, and the results of their operations and their cash flows for the year
then ended in conformity with generally accepted accounting principles.
 
     As discussed in Note 20 the accompanying 1998 consolidated financial
statements have been restated.

                               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. For the year ended September 30,
1998, the Company experienced an 8% decline in revenue of approximately $4.0
million and a substantial operating loss amounting to approximately $34.6
million (approximately $15.1 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, technology 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 enhancement in the form of debt guarantees for
the Company. On November 30, 1998, the Company completed a preferred stock
private placement (the "Private Placement" see Note 17), resulting in net
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, used
$2 million to repay debt and the balance is being 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 Chairman has committed to provide the
Company with $30 million of long-term financing through July 1, 2000. The
Chairman's financing commitment terminates if the Company completes a secondary
offering of approximately $40.0 million. 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

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
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. If
the working capital generated from the Private Placement and cash generated from
operations is 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
 
     Interim Financial Information.  The financial information as of March 31,
1999 and for the six-month periods ended March 31, 1998 and 1999 is unaudited,
but includes all adjustments (consisting only of normal recurring accruals) that
the Company considers necessary for a fair presentation of the financial
position at such date and the operating results and cash flows for those
periods. Operating results for the six months ended March 31, 1999 are not
necessarily indicative of the results that may be expected for the entire year.
 
     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.
 
     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 $2.3 million and $3.0
million 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

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
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. Total amortization expense 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 ("Black
Scholes"). 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, as applicable, evaluates 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.
 
     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

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
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 durations 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 recorded a
charge of $19,516,000 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 accounts for earnings per share under the
provisions of Statement of Financial Accounting Standards No. 128 "Earnings per
Share" ("SFAS No. 128"). Basic and diluted earnings per share calculated
pursuant to SFAS 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 loss 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 is required to adopt this standard in its fiscal year ended
September 30, 1999. The adoption of SFAS No. 131 will not 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 15,
1998. SOP 98-1 provides guidance over accounting for computer software developed
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 on its 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. The adoption of
this standard is not expected to have a significant impact on its results of
operations, financial position or cash flows.
 
     In June of 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities." This statement establishes accounting and
reporting standards for derivative instruments and requires recognition of all
derivatives as assets or liabilities in the statement of financial position and
measurement of these instruments at fair value. The statement is effective for
fiscal years beginning after June 15, 1999. Management believes that adopting
this statement will not have a material impact on the financial position,
results of operations, or cash flows of the Company.

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 acquisition 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:

</TABLE>
 
     The common stock issued in connection with the MODE acquisition was valued
based upon the average closing price of the Company's common stock for the five
days before and after the announcement date of the acquisition. The assumed MODE
options and warrants were valued using Black-Scholes and such values amounted to
approximately $3,761,000 and $793,000, respectively.
 
     The MODE options have a term of 10 years from the date of grant, with such
options expiring at various dates through July 2007. The options vest, with
continued service, over a four-year period; 25% in year one and 75% equally over
the remaining 36 months. The warrants have a term of 10 years from the date of
grant, were exercisable upon grant, and expire at various dates through May
2007.
 
     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 optical laser devices at the
date of acquisition.
 
     Management is responsible for estimating the fair value of the acquired
in-process research and development. As of the date of acquisition, MODE had six
primary micro-optical laser research and development projects in-process, which
had not reached technological feasibility. MODE's in-process research and
development related to new technologies, the fair value assumptions relating to
pricing, product margins and expense levels were based upon management's
experience with its own operations and the compound semiconductor industry as a
whole.
 
     The Company allocated $475,000 of the purchase price to the acquired
workforce of MODE which is included in the approximately $13.2 million of
goodwill discussed above. The amount allocated to 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 and October 1, 1997, respectively, but does not
reflect the non-recurring write-off of the acquired in-process research and

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 Black
Scholes. 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 (8.75% 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 quarters ended June 30, 1998 and
September 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 Company's 1997 Agreement was
subsequently further extended through October 1, 1999. The 1997 Agreement's
financial covenants were modified under the second amendment, and management
believes that the Company will be able to comply with such requirements
throughout fiscal 1999. In addition, the Company's Chairman has guaranteed 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
 
                                      F-19

                               EMCORE CORPORATION
 
                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
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 $370,000, $388,000 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 the rate of Prime plus 200 basis points (10.25% as of
September 30, 1998), 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 (see Note 17).
 
     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 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).
 
     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 $637,000 for the years ended September 30,
1996, 1997 and 1998, respectively.
 
     Future minimum rental payments under the Company's non-cancelable operating

     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. The notes receivable
mature and are payable in full on May 1, 2001 and bear interest at a rate of 6%,
compounding semi-annually. 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. In February
1997, options to acquire an additional 725,000 shares of common stock were
approved. As of September 30, 1998, 1,372,059 stock options were available for
issuance under the Company's Option Plan.
 
     Certain options under the Option Plan are intended to qualify as incentive
stock options pursuant to Section 422A of the Internal Revenue Code.
 
     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.

     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

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

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 formed
Uniroyal Optoelectronics, a venture (the "UTC Venture") to produce and market
compound semiconductor 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. In July 1998, the Company invested $490,000 in the UTC
Venture which was 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 the UTC Venture, which has been recorded as a component of other income and
expense.
 
     In November 1998, the Company invested an additional $5.0 million into the
UTC Venture. During the six months ended March 31, 1999, the Company sold three
compound semiconductor production systems to the UTC Venture totaling $5.3
million in revenues. The Company eliminated gross profit of approximately $1.3
million on such sales to the extent of its minority interest. Such deferred
gross profit will be recognized ratably over the assigned life of the UTC
Venture's production systems. For the six months and the year ended March 31,
1999 and September 30, 1998, respectively, the Company recognized a loss of $1.0
million and $198,000 related to this venture, which has been recorded as a
component of other income and expense. As of March 31, 1999, the Company's
investment in this venture amounted to $4.3 million.
 
     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. During the six months ended
March 31, 1999, sales made through Hakuto amounted to approximately $5.1
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).

20. RESTATEMENT
 
     Subsequent to the issuance of the Company's Annual Report on Form 10-K for
the year ended September 30, 1998, the Company's management revised the amount
of the purchase price which was allocated to in-process research and development
in accounting for the acquisition of MicroOptical Devices, Inc. ("MODE") in
December 1997. The revised allocation is based upon methods prescribed in a
letter from the Securities and Exchange Commission ("SEC") sent to the American
Institute of Certified Public Accountants. The letter sets forth the SEC's views
regarding the valuation methodology to be used in allocating a portion of the
purchase price to acquired in-process research and development ("IPR&D") at the
date of acquisition.
 
     The revised valuation is based on management's estimates of the net cash
flows associated with expected operations of MODE and gives explicit
consideration to the SEC's views on acquired IPR&D as set forth in its letter to
the American Institute of Certified Public Accountants.
 
     As a result of the revised allocation, the Company's financial statements
for the year ended September 30, 1998, have been restated from amounts
previously reported to reduce the amount of the acquired in-process research and
development expensed by $9.8 million and to increase goodwill by $9.8 million.
The amount allocated to goodwill includes approximately $0.5 million related to
the value of MODE's workforce. The change had no impact on net cash flows used
by operations.
 
     A summary of the significant effects of the restatement is as follows:

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To the Stockholders and Board of Directors of
MicroOptical Devices, Inc.:
 
     We have audited the accompanying balance sheets of MICROOPTICAL DEVICES,
INC. (a Delaware corporation in the development stage) (the "Company") as of
December 31, 1996 and 1995, and the related statements of operations,
stockholders' equity and cash flows for the year ended December 31, 1996 and for
the period from inception (August 3, 1995) through December 31, 1995 and 1996.
These financial statements are the responsibility of the Company's management.
Our responsibility is to express an opinion on these financial statements based
on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of MicroOptical Devices, Inc.
as of December 31, 1996 and 1995, and the results of its operations and its cash
flows for the year ended December 31, 1996 and for the period from inception
(August 3, 1995) through December 31, 1995 and 1996, in conformity with
generally accepted accounting principles.

NOTE 1. ORGANIZATION AND SUMMARY OF SIGNIFICANT RISK FACTORS
 
     MicroOptical Devices, Inc. (the "Company" or "MODE"), was incorporated
under the laws of the State of Delaware on August 3, 1995 for the purpose of
developing technology and manufacturing of advanced optoelectronic components
and systems for specific use in commercial identification and communications
markets.
 
     The Company funded its marketing, development and operational activities to
date from the proceeds of two equity offerings. Since inception, the Company has
devoted substantially all of its efforts and resources to marketing and
development of its technology and remains in the development stage. Ultimately,
the Company's ability to achieve profitable operations is dependent, in large
part, upon making the transition to a manufacturing company.
 
     On July 16, 1996, an amendment to the Certificate of Incorporation of MODE
(the "Amendment") was filed, which (a) increased the total number of its common
shares, which the Company is authorized to issue from two million to four
million, and (b) increased the total number of authorized shares of its
Convertible Preferred Stock, from four thousand to two million (222,222 shares
of Series A Convertible Preferred Stock and 1,777,778 shares of Series B
Convertible Preferred Stock).
 
NOTE 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
     Accounting Basis.  The financial books and records of the Company are
maintained on the accrual basis of accounting. As a development stage company,
cumulative results of operations from inception are presented.
 
     Use of Estimates.  The preparation of financial statements in conformity
with generally accepted accounting principles requires management to make
estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the date of
the financial statements and the reported amounts of revenues and expenses
during the reporting period. Actual results could differ from those estimates.
 
     Cash Equivalents.  For the purposes of presenting cash flows, cash and cash
equivalents represent cash balances and highly liquid investments with original
maturities of less than 90 days.
 
     Inventory.  Inventories are stated at the lower of standard cost (which
approximates actual cost using the first-in, first-out method) or market and
consist of raw materials.
 
     Property and Equipment.  Equipment is stated at cost, net of accumulated
depreciation. Depreciation is computed on the straight-line method based on
estimated useful lives ranging from three to five years. Leasehold improvements
are amortized

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
using the straight-line method over the shorter of the estimated useful life of
the asset or the remaining term of the lease.
 
     Organization Costs.  Costs to organize the Company are capitalized and
amortized on a straight-line basis over five years.
 
     Research and Development.  The costs of research and development activities
are charged to expense as incurred.
 
     Fair Value of Financial Instruments.  The carrying value of all financial
instruments approximates fair market value at December 31, 1996 and 1995.
 
     Stock-Based Compensation.  The Company accounts for stock-based
compensation using the intrinsic value method prescribed in Accounting
Principles Board Opinion No. 25 ("APB Opinion No. 25"), "Accounting for Stock
Issued to Employees," and related Interpretations. Accordingly, compensation
cost for stock options is measured as the excess, if any, of the quoted market
price of the Company's stock at the date of the grant over the amount an
employee must pay to acquire the stock. Financial Accounting Standards Board
Statement No. 123, "Accounting for Stock-Based Compensation" ("SFAS 123"), was
issued in 1995 and the Company has adopted the disclosure requirements of SFAS
123 (see Note 6).
 
     Income Taxes.  MODE accounts for income taxes using the asset and liability
method. Deferred tax assets and liabilities are recognized for the future tax
consequences attributable to differences between the financial statement
carrying amounts of existing assets and liabilities and their respective tax
bases and operating loss and tax credit carryforwards. Deferred tax assets and
liabilities are measured using enacted tax rates expected to apply to taxable
income in the years in which those temporary differences are expected to be
recovered or settled. Under Financial Accounting Standards Board Statement No.
109, "Accounting for Income Taxes" ("SFAS No. 109"), the effect on deferred tax
assets and liabilities of a change in tax rates is recognized in operations in
the period that includes the enactment date.
 
     Net Loss Per Share.  Net loss per share for each period was calculated
based upon the weighted average number of Common Stock outstanding during each
period, using post split shares resulting from the three- for-one stock split
effective August 1996. Common Stock equivalents were excluded in the calculation
of weighted average shares outstanding since their inclusion would have had an
anti-dilutive effect.
 
     Accounting Pronouncement Not Yet Adopted.  The Financial Accounting
Standards Board issued SFAS No. 128, "Earnings Per Share," which is effective
for calendar years beginning after December 15, 1997 at which time it will
require restatement of prior years earnings per share calculations. Management
has not yet determined the effect, if any, of SFAS No. 128 on the financial
statements.

NOTE 4. CAPITAL LEASES
 
     In 1996, the Company financed certain manufacturing equipment, leasehold
improvements, and furniture and fixtures under a Master Equipment Lease
Agreement ("the Lease") expiring June 30, 1997, which provides for financing of
up to $2,000,000. The Company had only nominal borrowings under the Lease at
December 31, 1996. The capital leases have terms of 42 months and are
collateralized by manufacturing equipment. The transactions under the Lease are
accounted for as a financing, whereby the property remains on the books and
continues to be depreciated and amortized. Obligations under capital leases
representing the proceeds was recorded, and is reduced based on payments under
capital lease obligations. All items are sold and leasedback at original
purchase price, therefore no gain or loss was recorded on such transactions
during 1996.
 
     At December 31, 1996, approximately $146,000 of manufacturing equipment was
under capital lease. The future minimum lease payments for assets under capital
lease and the present value of the net minimum lease payments at December 31,
1996, are as follows:

     In connection with the Lease, the Company issued a warrant to purchase

years ending on August 21,

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
2006 at a price of $.77 per share. The warrant may terminate sooner in
connection with certain significant corporate events.
 
NOTE 5. STOCKHOLDERS' EQUITY
 
     Effective August, 1996, the Company declared a stock split on all existing
preferred and common shares at a ratio of three to one. The accompanying
financial statements for the year ended December 31, 1996, have been adjusted to
reflect the stock split.
 
     On July 17, 1996, the Company issued 4,076,088 shares, on a post stock
split basis, of its Series B Convertible Preferred Stock ("Series B"). Each
share of Series B, which has a liquidation preference of $.77, is convertible to
one share of the Company's Common Stock and earns dividends at the rate declared
for each share of Common Stock. No such dividends have been declared as of
December 31, 1996. Terms of the agreements with Preferred Shareholders require
the Company to comply with terms similar to those specified in the Series A
issuance.
 
     As specified in the Series A Convertible Preferred Stock ("Series A")
issuance, the Series A Preferred Stockholder purchased $150,000 of Convertible
Promissory Notes (the "Notes"), during 1996. The Notes, which bore interest at
the prime rate compounded monthly, were convertible at a price equal to the per
share purchase price of the Series B stock issuance. On July 17, 1996, the Notes
and the related interest of $1,169 were converted to Series B convertible
preferred stock in conjunction with the Series B stock issuance.
 
     On August 29, 1995, the Company issued 666,666 shares, on a post stock
split basis, of its Series A. Each share of Series A, which has a liquidation
preference of $.3, is convertible to one share of the Company's Common Stock and
earns dividends at the rate declared for each share of Common Stock. No such
dividends have been declared as of December 31, 1996. An agreement with the
Series A Preferred Stockholder requires the Company to, among other items,
maintain keyman life insurance on certain key employees, and obtain the
Preferred Stockholders' approval to make key changes in the operations of the
Company.
 
     On August 3, 1995, the Company issued 3,000,000 shares, on a post stock
split basis, of its Common Stock at a par value of $.001 per share.
 
NOTE 6. DEFERRED COMPENSATION PLAN
 
     In July 1996, the Company adopted the 1996 Stock Option Plan (the "Plan"),
where options granted to an employee are qualified "incentive stock options"
under the Internal Revenue Code and options granted to a non-employee are
"non-statutory stock options", for which 1,800,000 shares were reserved, on a
post stock split basis. The Company accounts for options granted to employee's
under this Plan in accordance with APB Opinion No. 25, under which no
compensation cost has been recognized. The compensation costs for the Plan
determined consistent with SFAS 123

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
is immaterial. Options granted to non-employee's under this Plan are accounted
for in accordance with the provisions of SFAS 123.
 
     The Company has granted options on 645,500 shares through December 31,
1996. Under the Plan, the option exercise price equals the common stocks market
price on date of grant. All options are immediately exercisable and expire ten
years from date of grant. The options granted to MODE's founders are subject to
repurchase by the Company, at the original exercise price, upon the cessation of
service prior to vesting in such shares. Such shares vest in a series of 72
successive equal monthly installments over a six year period, however, such
vesting shall accelerate to 48 successive equal monthly installments upon the
Company meeting performance milestones as provided for by the Board. At December
31, 1996, the Company has achieved two out of five of its performance measures.
All other shares vest at the rate of 25 percent of the shares upon the
optionee's continued service to the Company through the initial vesting date,
with the remaining shares vesting in a series of 36 successive equal monthly
installments. The vesting period accelerates in connection with certain
significant corporate events.
 
     A summary of the status of the Company's option Plan at December 31, 1996,
and changes during the year then ended is presented in the table and narrative

     The options outstanding at December 31, 1996, have a weighted average
remaining contractual life of 9.5 years.
 
     The fair value of each option grant is estimated on the date of grant using
Black-Scholes option pricing model with the following average assumptions used:
risk-free interest rate of 6.65%; expected lives of ten years; a divided yield
of 0%; and expected volatility of .01%.

NOTE 8. COMMITMENTS AND CONTINGENCIES
 
     Technology Assistance and Royalty Agreement.  On February 22, 1996, the
Company entered into a technical assistance and royalty agreement (as
subsequently amended) in which the Company agreed to further develop laser
technology in return for eight years of co-exclusive rights to five existing
patents covering this technology. The Company is required to pay $7,500 in 1997,
plus royalty payments beginning in 1998 of 1.5% to 2.5%, subject to minimum
annual payments ranging from up to $50,000 over the life of the patents provided
that the technology is developed and the related products are manufactured in
Albuquerque, New Mexico. In the event that the Company fails to develop or
abandons development of this technology, all rights to the technology become
nonexclusive. The Company paid $7,500 under this Agreement in 1996.
 
     In October, 1996, the Company signed an agreement for research and
development, which expires March 31, 1998. Under the Agreement, the Buyer paid
the Company $95,000 for non-recurring engineering expense, plus all applicable
fees and taxes, which payment is non-refundable. Buyer will pay MODE the balance
of the payment upon demonstration of feasibility.

insurance for each of its two founders.
 
   
     Licensing Agreement.  On March 21, 1996, the Company signed a license
agreement (the "Agreement") with a major manufacturer in the identification
market (the "Manufacturer"). Under the Agreement, the Manufacturer paid the
Company a $500,000 license fee (the "Payment") plus all applicable gross
receipts tax that the Company is required to pay thereon.
    
 
     The Manufacturer retains exclusive rights to use and sell any products or
components which the Company develops for the Manufacturer's portion of the
identification market (the "Product") for a limited period of time. After the
exclusive rights period expires, the Company is required to first offer these
Products, if achieved to the Manufacturer under similar sales terms as the
Products are offered to any other party for a limited period of time.
 
     Within approximately one year of the receipt of the Payment, the Company
and the Manufacturer will negotiate in good faith to enter into a supply
agreement for the Product, if achieved. If no agreement is reached, then the
Company can elect to sell the Product, if achieved to the Manufacturer for an
additional license fee and, for each Product sold, the cost of the Product plus
a specified factor for overhead and profit.
 
     Should the Company fail to pursue development or sell the Product to the
Manufacturer, the Manufacturer will be granted certain nonexclusive
sub-licensing rights.
 
     At December 31, 1996, $325,000 has been earned under the terms of this
agreement.
 
     Leased Property.  The Company leases its facility under an operating lease
with a term of three years. Rental expense under operating leases was $18,214

commitments for all operating leases are $34,332 for each of the years ending
December 31, 1997 and 1998 and $17,166 for year end December 31, 1999.

purchase and supply contract (the "Contract"). Under the Contract, MODE
established the terms and conditions controlling potential sales of
vertical-cavity surface-emitting laser ("VCSEL") chips, devices and arrays in
the event they occur. The initial term of the Contract is five years, and can be
canceled by either party upon written notice 360 days prior to the end of the
initial term or any subsequent term. The Contract also may terminate prior to
the five year period under certain circumstances. Products sold under the
agreement are subject to a warranty period not to exceed the earlier of 18
months from the date the product is delivered to customer,

     EMCORE's Restated Certificate of Incorporation provides that the Company
shall indemnify its directors and officers to the full extent permitted by New
Jersey law, including in circumstances in which indemnification is otherwise
discretionary under New Jersey law.
 
     Section 14A:2-7 of the New Jersey Business Corporation Act provides that a
New Jersey corporation's:
 
     "certificate of incorporation may provide that a director or officer shall
not be personally liable, or shall be liable only to the extent therein
provided, to the corporation or its shareholders for damages for breach of any
duty owed to the corporation or its shareholders, except that such provision
shall not relieve a director or officer from liability for any breach of duty
based upon an act or omission (a) in breach of such person's duty of loyalty to
the corporation or its shareholders, (b) not in good faith or involving a
knowing violation of law or (c) resulting in receipt by such person of an
improper personal benefit. As used in this subsection, an act or omission in

other than a proceeding by or in the right of the corporation, if
 
          (a) such corporate agent acted in good faith and in a manner he
     reasonably believed to be in or not opposed to the best interests of the
     corporation; and
 
          (b) with respect to any criminal proceeding, such corporate agent had
     no reasonable cause to believe his conduct was unlawful. The termination of
     any proceeding by judgment, order, settlement, conviction or upon a plea of
     nolo contendere or its equivalent, shall not of itself create a presumption
     that such
 
                                      II-2
<PAGE>   124
 
     corporate agent did not meet the applicable standards of conduct set forth
     in paragraphs 14A:3-5(2)(a) and 14A:3-5(2)(b).
 
     (3) Any corporation organized for any purpose under any general or special
law of this State shall have the power to indemnify a corporate agent against
his expenses in connection with any proceeding by or in the right of the
corporation to procure a judgment in its favor which involves the corporate
agent by reason of his being or having been such corporate agent, if he acted in
good faith and in a manner he reasonably believed to be in or not opposed to the
best interests of the corporation. However, in such proceeding no
indemnification shall be provided in respect of any claim, issue or matter as to
which such corporate agent shall have been adjudged to be liable to the
corporation, unless and only to the extent that the Superior Court or the court
in which such proceeding was brought shall determine upon application that
despite the adjudication of liability, but in view of all circumstances of the
case, such corporate agent is fairly and reasonably entitled to indemnity for
such expenses as the Superior Court or such other court shall deem proper.
 
     (4) Any corporation organized for any purpose under any general or special
law of this State shall indemnify a corporate agent against expenses to the
extent that such corporate agent has been successful on the merits or otherwise
in any proceeding referred to in subsections 14A:3-5(2) and 14A:3-5(3) or in
defense of any claim, issue or matter therein.
 
     (5) Any indemnification under subsection 14A:3-5(2) and, unless ordered by
a court, under subsection 14A:3-5(3) may be made by the corporation only as
authorized in a specific case upon a determination that indemnification is
proper in the circumstances because the corporate agent met the applicable
standard of conduct set forth in subsection 14A:3-5(2) or subsection 14A:3-5(3).
Unless otherwise provided in the certificate of incorporation or bylaws, such
determination shall be made
 
          (a) by the board of directors or a committee thereof, acting by a
     majority vote of a quorum consisting of directors who were not parties to
     or otherwise involved in the proceeding; or
 
          (b) if such a quorum is not obtainable, or, even if obtainable and
     such quorum of the board of directors or committee by a majority vote of
     the disinterested directors so directs, by independent legal counsel, in a
     written opinion, such counsel to be designated by the board of directors;
     or
 
          (c) by the shareholders if the certificate of incorporation or bylaws
     or a resolution of the board of directors or of the shareholders so
     directs.
 
     (6) Expenses incurred by a corporate agent in connection with a proceeding
may be paid by the corporation in advance of the final disposition of the
proceeding as authorized by the board of directors upon receipt of an
undertaking by or on behalf of the corporate agent to repay such amount if it
shall ultimately be determined that he is not entitled to be indemnified as
provided in this section.
 
     (7) (a) If a corporation upon application of a corporate agent has failed
or refused to provide indemnification as required under subsection 14A:3-5(4) or
permitted under subsections 14A:3-5(2), 14A:3-5(3) and 14A:3-5(6), a corporate
agent may apply to a court for an award of indemnification by the corporation,
and such court
 
                                      II-3
<PAGE>   125
 
              (i) may award indemnification to the extent authorized under
         subsections 14A:3-5(2) and 14A:3-5(3) and shall award indemnification
         to the extent required under subsection 14A:3-5(4), notwithstanding any
         contrary determination which may have been made under subsection
         14A:3-5(5); and
 
              (ii) may allow reasonable expenses to the extent authorized by,
         and subject to the provisions of, subsection 14A:3-5(6), if the court
         shall find that the corporate agent has by his pleadings or during the
         course of the proceeding raised genuine issues of fact or law.
 
          (b) Application for such indemnification may be made:
 
              (i) in the civil action in which the expenses were or are to be
         incurred or other amounts were or are to be paid; or
 
              (ii) to the Superior Court in a separate proceeding. If the
         application is for indemnification arising out of a civil action, it
         shall set forth reasonable cause for the failure to make application
         for such relief in the action or proceeding in which the expenses were
         or are to be incurred or other amounts were or are to be paid.
 
     The application shall set forth the disposition of any previous application
for indemnification and shall be made in such manner and form as may be required
by the applicable rules of court or, in the absence thereof, by direction of the
court to which it is made. Such application shall be upon notice to the
corporation. The court may also direct that notice shall be given at the expense
of the corporation to the shareholders and such other persons as it may
designate in such manner as it may require.
 
     (8) The indemnification and advancement of expenses provided by or granted
pursuant to the other subsections of this section shall not exclude any other
rights, including the right to be indemnified against liabilities and expenses
incurred in proceedings by or in the right of the corporation, to which a
corporate agent may be entitled under a certificate of incorporation, bylaw,
agreement, vote of shareholders, or otherwise; provided that no indemnification
shall be made to or on behalf of a corporate agent if a judgment or other final
adjudication adverse to the corporate agent establishes that his acts or
omissions (a) were in breach of his duty of loyalty to the corporation or its
shareholders, as defined in subsection (3) of N.J.S.14A:2-7, (b) were not in
good faith or involved a knowing violation of law or (c) resulted in receipt by
the corporate agent of an improper personal benefit.
 
     (9) Any corporation organized for any purpose under any general or special
law of this State shall have the power to purchase and maintain insurance on
behalf of any corporate agent against any expenses incurred in any proceeding
and any liabilities asserted against him by reason of his being or having been a
corporate agent, whether or not the corporation would have the power to
indemnify him against such expenses and liabilities under the provisions of this
section. The corporation may purchase such insurance from, or such insurance may
be reinsured in whole or in part by, an insurer owned by or otherwise affiliated
with the corporation, whether or not such insurer does business with other
insureds.
 
                                      II-4
<PAGE>   126
 
     (10) The powers granted by this section may be exercised by the
corporation, notwithstanding the absence of any provision in its certificate of
incorporation or bylaws authorizing the exercise of such powers.
 
     (11) Except as required by subsection 14A:3-5(4), no indemnification shall
be made or expenses advanced by a corporation under this section, and none shall
be ordered by a court, if such action would be inconsistent with a provision of
the certificate of incorporation, a bylaw, a resolution of the board of
directors or of the shareholders, an agreement or other proper corporate action,
in effect at the time of the accrual of the alleged cause of action asserted in
the proceeding, which prohibits, limits or otherwise conditions the exercise of
indemnification powers by the corporation or the rights of indemnification to
which a corporate agent may be entitled.
 
     (12) This section does not limit a corporation's power to pay or reimburse
expenses incurred by a corporate agent in connection with the corporate agent's
appearance as a witness in a proceeding at a time when the corporate agent has
not been made a party to the proceeding.
 
     The Underwriting Agreement provides for indemnification by the Underwriters
of the Registrant and its officers and directors for certain liabilities,
including liabilities under the Securities Act.

ITEM 17.  UNDERTAKINGS
 
     The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to Section 13(a)or 15(d) of the Securities
Exchange Act of 1934 (and, where applicable, each filing of an employee benefit
plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of
1934) that is incorporated by reference in the registration statement shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.
 
     Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the foregoing provisions, or otherwise, the Registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Securities Act
and is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the Registrant of expenses
incurred or paid by a director, officer or controlling person of the Registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act and will be governed by the final
adjudication of such issue.
 
     The undersigned Registrant hereby undertakes that:
 
          (1) For purposes of determining any liability under the Securities Act
     of 1933, the information omitted from the form of prospectus filed as part
     of a registration statement in reliance upon Rule 430A and contained in the
     form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or
     (4) or 497(h) under the Securities Act shall be deemed to be part of this
     registration statement as of the time it was declared effective.
 
          (2) For the purpose of determining any liability under the Securities
     Act of 1933, each post-effective amendment that contains a form of
     prospectus shall be deemed to be a new registration statement relating to
     the securities offered therein, and the offering of such securities at that
     time shall be deemed to be the initial bona fide offering thereof.

          (j) The execution, delivery and performance of this Agreement by the

that is material to the Company and its subsidiaries, taken as a whole, to

or conflict with any applicable law or any rule, regulation, judgment, order or
decree of any court or any governmental body or agency having jurisdiction over

result in the suspension, termination or revocation of any Authorization (as

          (k) There are no legal or governmental proceedings pending or

          (l) Neither the Company nor any of its subsidiaries has violated any
foreign, federal, state or local law or regulation relating to the protection
of human health and safety, the environment or hazardous or toxic substances or
wastes, pollutants or contaminants ("ENVIRONMENTAL LAWS"), any federal or state
law relating to discrimination in the hiring, promotion or pay of employees,
any applicable federal or state wages and hours laws, any provisions of the
Employee Retirement Income Security Act of 1974, as amended, or any provisions
of the Foreign Corrupt Practices Act or the rules and regulations promulgated
thereunder, except for such violations which, singly or in the aggregate, would
not have a material adverse effect on the business, prospects, financial
condition or results of operation of the Company and its subsidiaries, taken as
a whole.

          (m) Each of the Company and its subsidiaries has such permits,
licenses, consents, exemptions, franchises, authorizations and other approvals
(each, an "AUTHORIZATION") of, and has made all filings with and notices to,
all governmental or regulatory authorities and self-regulatory organizations
and all courts and other tribunals, including, without limitation, under any
applicable Environmental Laws, as are necessary to own, lease, license and
operate its respective properties and to conduct its business, except where the
failure to have any such Authorization or to make any such filing or notice
would not, singly or in the aggregate, have a material adverse effect on the
business, prospects, financial condition or results of operations of the
Company and its subsidiaries, taken as a whole. Each such Authorization is
valid and in full force and effect and each of the Company and its subsidiaries
is in compliance with all the terms and conditions thereof and with the rules
and regulations of the authorities and governing bodies having jurisdiction
with respect thereto; and no event has occurred (including, without limitation,
the receipt of any notice from any authority or governing body) which allows
or, after notice or lapse of time or both, would allow, revocation, suspension
or termination of any such Authorization or results or, after notice or lapse
of time or both, would result in any other impairment of the rights of the
holder of any such Authorization; and such Authorizations contain no
restrictions that are burdensome to the Company or any of its subsidiaries;
except where such failure to be valid and in full force and effect or to be in
compliance, the occurrence of any such event or the presence of any such
restriction would not, singly or in the aggregate, have a material adverse
effect on the business, prospects, financial condition or results of operations
of the Company and its subsidiaries, taken as a whole.

          (n) In the ordinary course of its business, the Company conducts a
periodic review of the effect of Environmental Laws on the business, operations
and properties of the Company, in the course of which it identifies and
evaluates associated costs and liabilities (including, without limitation, any
capital or operating expenditures required for clean-up, closure of properties
or compliance with Environmental Laws or any permit, license or approval, any





                                      11
<PAGE>   12

related constraints on operating activities and any potential liabilities to
third parties). On the basis of such review, the Company has reasonably
concluded that such associated costs and liabilities would not, singly or in
the aggregate, have a material adverse effect on the business, prospects,
financial condition or results of operations of the Company and its
subsidiaries, taken as a whole.

          (o) This Agreement has been duly authorized, executed and delivered
by the Company.

          (p) PricewaterhouseCoopers LLP and Arthur Andersen LLP are each
independent public accountants with respect to the Company and its subsidiaries
as required by the Act.

          (q) The consolidated financial statements included in the
Registration Statement and the Prospectus (and any amendment or supplement
thereto), together with related schedules and notes, present fairly the
consolidated financial position, results of operations and changes in financial
position of the Company and its subsidiaries on the basis stated therein at the
respective dates or for the respective periods to which they apply; such
statements and related schedules and notes have been prepared in accordance
with generally accepted accounting principles consistently applied throughout
the periods involved, except as disclosed therein; the supporting schedules, if
any, included in the Registration Statement present fairly in accordance with
generally accepted accounting principles the information required to be stated
therein; and the other financial and statistical information and data set forth
in the Registration Statement and the Prospectus (and any amendment or
supplement thereto) are, in all material respects, accurately presented and
prepared on a basis consistent with such financial statements and the books and
records of the Company.

          (r) The Company is not and, after giving effect to the offering and
sale of the Shares and the application of the proceeds thereof as described in
the Prospectus, will not be, an "investment company" or a company "controlled"
by an "investment company", as such terms are defined in the Investment Company
Act of 1940, as amended.

          (s) Except as otherwise disclosed in the Registration Statement,
there are no contracts, agreements or understandings between the Company and
any person granting such person the right to require the Company to file a
registration statement under the Act with respect to any securities of the
Company or to require the Company to include such securities with the Shares
registered pursuant to the Registration Statement.

          (t) Since the respective dates as of which information is given in
the Prospectus other than as set forth in the Prospectus (exclusive of any
amendments or supplements thereto subsequent to the date of this Agreement),
(i) there has not occurred any material adverse change or any development
involving a prospective material adverse change in the condition, financial or





                                      12
<PAGE>   13

otherwise, or the earnings, business, management or operations of the Company
and its subsidiaries, taken as a whole, (ii) there has not been any material
adverse change or any development involving a prospective material adverse
change in the capital stock or in the long-term debt of the Company or any of
its subsidiaries and (iii) neither the Company nor any of its subsidiaries has
incurred any material liability or obligation, direct or contingent.

                (u) Each certificate signed by any officer of the Company and
delivered to the Underwriters or counsel for the Underwriters shall be deemed
to be a representation and warranty by the Company to the Underwriters as to
the matters covered thereby.

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

                  (x) The Company and its subsidiaries own, or possess valid
and enforceable licenses to all patents, patent rights, inventions, copyrights,
know-how (including trade secrets and other unpatented and/or unpatentable
proprietary or confidential information, systems or procedures), trademarks,
service marks and trade names ("INTELLECTUAL PROPERTY") currently employed by
the Company and its subsidiaries in connection with the business now operated
by them , except where the failure to own or possess such Intellectual Property
would not, singly or in the aggregate, have a material adverse effect on the
business, prospects, financial condition or results of operation of the Company
and its subsidiaries, taken as a whole. Neither the Company, nor its
subsidiaries, has received any notice, nor are they aware of facts which would
form a reasonable basis for any such claim, that: (i) challenges the Company's
or its subsidiaries' rights in or to any Intellectual Property; (ii) challenges
the validity or scope of any Intellectual Property; (iii) any third party has
or will be able to establish any rights in the Intellectual Property, except
for the ownership rights of the owners of the Intellectual Property which is
licensed to the Company or the rights of parties to whom the Company has
granted licenses of such Intellectual Property; (iv) the Intellectual Property





                                      13
<PAGE>   14

infringes or otherwise violates any patent, copyright, trade secret, trademark
or other proprietary right of any third party; or (v) there is infringement of
the Intellectual Property by any third party, which, in the case of any such
claim specified in clauses (i), (ii), (iii), (iv) or (v) above, singly or in
the aggregate, if the subject of an unfavorable decision, ruling or finding,
would have a material adverse effect on the business, prospects, financial
condition or results of operations of the Company and its subsidiaries, taken
as a whole.

                  (y) The Company and each of its subsidiaries are insured by
insurers of recognized financial responsibility against such losses and risks
and in such amounts as are prudent and customary in the businesses in which
they are engaged; and neither the Company nor any of its subsidiaries (i) has
received notice from any insurer or agent of such insurer that substantial
capital improvements or other material expenditures will have to be made in
order to continue such insurance or (ii) has any reason to believe that it will
not be able to renew its existing insurance coverage as and when such coverage
expires or to obtain similar coverage from similar insurers at a cost that
would not have a material adverse effect on the business, prospects, financial
conditions or results of operations of the Company and its subsidiaries, taken
as a whole.

                  (z) No relationship, direct or indirect, exists between or
among the Company or any of its subsidiaries on the one hand, and the
directors, officers, shareholders, customers or suppliers of the Company or any
of its subsidiaries on the other hand, which is required by the Act to be
described in the Registration Statement or the Prospectus which is not so
described.

                  (aa) There is no (i) significant unfair labor practice
complaint, grievance or arbitration proceeding pending or, to the Company's
best knowledge, threatened against the Company or any of its subsidiaries
before the National Labor Relations Board or any state or local labor relations
board, (ii) strike, labor dispute, slowdown or stoppage pending or, to the
Company's best knowledge, threatened against the Company or any of its
subsidiaries or (iii) union representation question existing with respect to
the employees of the Company and its subsidiaries, except for such actions
specified in clause (i), (ii) or (iii) above, which, singly or in the
aggregate, would not have a material adverse effect on the business, prospects,
financial condition or results of operations of the Company and its
subsidiaries, taken as a whole. To the best of the Company's knowledge, no
collective bargaining organizing activities are taking place with respect to
the Company or any of its subsidiaries.

                  (bb) The Company and each of its subsidiaries maintains a
system of internal accounting controls sufficient to provide reasonable
assurance that (i) transactions are executed in accordance with management's
general or specific authorizations; (ii) transactions are recorded as necessary
to permit preparation of financial statements in conformity with generally
accepted accounting principles and to maintain asset accountability; (iii)
access to assets is permitted only in accordance with management's general or
specific authorization; and (iv) the recorded accountability for assets is
compared with the existing assets at reasonable intervals and appropriate
action is taken with respect to any differences.






                                      14
<PAGE>   15

                (cc) All material tax returns required to be filed by the
Company and each of its subsidiaries in any jurisdiction have been filed, other
than those filings being contested in good faith, and all material taxes,
including withholding taxes, penalties and interest, assessments, fees and
other charges due pursuant to such returns or pursuant to any assessment
received by the Company or any of its subsidiaries have been paid, other than
those being contested in good faith and for which adequate reserves have been
provided.

                (dd) Any documents which at the date hereof are incorporated by
reference in the Registration Statement, the Prospectus or any amendment or
supplement thereto, or any preliminary prospectus (the "Incorporated
Documents") were filed in a timely manner and, when they were filed (or, if any
amendment with respect to any such document was filed, when such amendment was
filed), conformed with the requirements of the Securities Exchange Act of 1934
(the "Exchange Act") and did not contain an untrue statement of a material fact
or omit to state a material fact required to be stated therein or necessary to
make the statements therein not misleading.

                (ee) The Company has not taken and will not take, directly or
indirectly, any action designed to or that might reasonably be expected to
cause or result in stabilization or manipulation of the price of the Common
Stock to facilitate the sale or resale of the Shares.

                (ff) The Common Stock is registered pursuant to Section 12(g)
of the Exchange Act and is listed on The Nasdaq National Market, and the
Company has taken no action designed to, or likely to have the effect of,
terminating the registration of the Common Stock under the Exchange Act or
delisting the Common Stock from The Nasdaq National Market, nor has the Company
received any notification that the Commission or the National Association of
Securities Dealers, Inc. ("NASD") is contemplating terminating such
registration or listing.

<PAGE>   17

         SECTION 8. INDEMNIFICATION. (a) The Sellers, severally and not
jointly, agree to indemnify and hold harmless each Underwriter, its directors,
its officers and each person, if any, who controls any Underwriter within the
meaning of Section 15 of the Act or Section 20 of the Securities Exchange Act
of 1934, as amended (the "EXCHANGE ACT"), from and against any and all losses,
claims, damages, liabilities and judgments (including, without limitation, any
legal or other expenses incurred in connection with investigating or defending
any matter, including any action, that could give rise to any such losses,
claims, damages, liabilities or judgments) caused by any untrue statement or
alleged untrue statement of a material fact contained in the Registration
Statement (or any amendment thereto), the Prospectus (or any amendment or
supplement thereto) or any preliminary prospectus, or caused by any omission or
alleged omission to state therein a material fact required to be stated therein
or necessary to make the statements therein not misleading, except insofar as
such losses, claims, damages, liabilities or judgments are caused by any such
untrue statement or omission or alleged untrue statement or omission based upon
information relating to any Underwriter furnished in writing to the Company by
such Underwriter through you expressly for use therein PROVIDED, HOWEVER, that






                                      17
<PAGE>   18

the foregoing indemnity agreement with respect to any preliminary prospectus
shall not inure to the benefit of any Underwriter who failed to deliver a
Prospectus, as then amended or supplemented, (so long as the Prospectus and any
amendment or supplement thereto was provided by the Company to the several
Underwriters in the requisite quantity and on a timely basis to permit proper
delivery on or prior to the Closing Date) to the person asserting any losses,
claims, damages, liabilities or judgments caused by any untrue statement or
alleged untrue statement of a material fact contained in such preliminary
prospectus, or caused by any omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements
therein not misleading, if such material misstatement or omission or alleged
material misstatement or omission was cured in the Prospectus, as so amended or
supplemented, and such Prospectus was required by law to be delivered at or
prior to the written confirmation of sale to such person. Notwithstanding the
foregoing, the aggregate liability of any Selling Stockholder pursuant to this
Section 8(a) shall be limited to an amount equal to the total proceeds (before
deducting underwriting discounts and commissions and expenses) received by such
Selling Stockholder from the Underwriters for the sale of the Shares sold by
such Selling Stockholder hereunder.

          (b) Each Underwriter agrees, severally and not jointly, to indemnify
and hold harmless the Company, its directors, its officers who sign the
Registration Statement, each person, if any, who controls the Company within
the meaning of Section 15 of the Act or Section 20 of the Exchange Act, each
Selling Stockholder and each person, if any, who controls such Selling
Stockholder within the meaning of Section 15 of the Act or Section 20 of the
Exchange Act to the same extent as the foregoing indemnity from the Sellers to
such Underwriter but only with reference to information relating to such
Underwriter furnished in writing to the Company by such Underwriter through you
expressly for use in the Registration Statement (or any amendment thereto), the
Prospectus (or any amendment or supplement thereto) or any preliminary
prospectus.

          (c) In case any action shall be commenced involving any person in
respect of which indemnity may be sought pursuant to Section 8(a) or 8(b) (the
"INDEMNIFIED PARTY"), the indemnified party shall promptly notify the person
against whom such indemnity may be sought (the "INDEMNIFYING PARTY") in writing
and the indemnifying party shall assume the defense of such action, including
the employment of counsel reasonably satisfactory to the indemnified party and
the payment of all fees and expenses of such counsel, as incurred (except that
in the case of any action in respect of which indemnity may be sought pursuant
to both Sections 8(a) and 8(b), the Underwriter shall not be required to assume
the defense of such action pursuant to this Section 8(c), but may employ
separate counsel and participate in the defense thereof, but the fees and
expenses of such counsel, except as provided below, shall be at the expense of
such Underwriter). Any indemnified party shall have the right to employ
separate counsel in any such action and participate in the defense thereof, but
the fees and expenses of such counsel shall be at the expense of the
indemnified party unless (i) the employment of such counsel shall have been






                                      18
<PAGE>   19

specifically authorized in writing by the indemnifying party, (ii) the
indemnifying party shall have failed to assume the defense of such action or
employ counsel reasonably satisfactory to the indemnified party or (iii) the
named parties to any such action (including any impleaded parties) include both
the indemnified party and the indemnifying party, and the indemnified party
shall have been advised by such counsel that there may be one or more legal
defenses available to it which are different from or additional to those
available to the indemnifying party (in which case the indemnifying party shall
not have the right to assume the defense of such action on behalf of the
indemnified party). In any such case, the indemnifying party shall not, in
connection with any one action or separate but substantially similar or related
actions in the same jurisdiction arising out of the same general allegations or
circumstances, be liable for (i) the fees and expenses of more than one
separate firm of attorneys (in addition to any local counsel) for all
Underwriters, their officers and directors and all persons, if any, who control
any Underwriter within the meaning of either Section 15 of the Act or Section
20 of the Exchange Act, (ii) the fees and expenses of more than one separate
firm of attorneys (in addition to any local counsel) for the Company, its
directors, its officers who sign the Registration Statement and all persons, if
any, who control the Company within the meaning of either such Section and
(iii) the fees and expenses of more than one separate firm of attorneys (in
addition to any local counsel) for all Selling Stockholders and all persons, if
any, who control any Selling Stockholder within the meaning of either such
Section, and all such fees and expenses shall be reimbursed as they are
incurred. In the case of any such separate firm for the Underwriters, their
officers and directors and such control persons of any Underwriters, such firm
shall be designated in writing by Donaldson, Lufkin & Jenrette Securities
Corporation. In the case of any such separate firm for the Company and such
directors, officers and control persons of the Company, such firm shall be
designated in writing by the Company. In the case of any such separate firm for
the Selling Stockholders and such control persons of any Selling Stockholders,
such firm shall be designated in writing by the Attorneys. The indemnifying
party shall indemnify and hold harmless the indemnified party from and against
any and all losses, claims, damages, liabilities and judgments by reason of any
settlement of any action (i) effected with its written consent or (ii) effected
without its written consent if the settlement is entered into more than twenty
business days after the indemnifying party shall have received a request from
the indemnified party for reimbursement for the fees and expenses of counsel
(in any case where such fees and expenses are at the expense of the
indemnifying party) and, prior to the date of such settlement, the indemnifying
party shall have failed to comply with such reimbursement request. No
indemnifying party shall, without the prior written consent of the indemnified
party, effect any settlement or compromise of, or consent to the entry of
judgment with respect to, any pending or threatened action in respect of which
the indemnified party is or could have been a party and indemnity or
contribution may be or could have been sought hereunder by the indemnified
party, unless such settlement, compromise or judgment (i) includes an
unconditional release of the indemnified party from all liability on claims
that are or could have been the subject matter of such action and (ii) does not
include a statement as to or an admission of fault, culpability or a failure to
act, by or on behalf of the indemnified party.







                                      19
<PAGE>   20

          (d) To the extent the indemnification provided for in this Section 8
is unavailable to an indemnified party or insufficient in respect of any
losses, claims, damages, liabilities or judgments referred to therein, then
each 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, damages, liabilities and judgments (i) in such
proportion as is appropriate to reflect the relative benefits received by the
Sellers on the one hand and the Underwriters on the other hand from the
offering of the Shares or (ii) if the allocation provided by clause 8(d)(i)
above is not permitted by applicable law, in such proportion as is appropriate
to reflect not only the relative benefits referred to in clause 8(d)(i) above
but also the relative fault of the Sellers on the one hand and the Underwriters
on the other hand in connection with the statements or omissions which resulted
in such losses, claims, damages, liabilities or judgments, as well as any other
relevant equitable considerations. The relative benefits received by the
Sellers on the one hand and the Underwriters on the other hand shall be deemed
to be in the same proportion as the total net proceeds from the offering (after
deducting underwriting discounts and commissions, but before deducting
expenses) received by the Sellers, and the total underwriting discounts and
commissions received by the Underwriters, bear to the total price to the public
of the Shares, in each case as set forth in the table on the cover page of the
Prospectus. The relative fault of the Sellers on the one hand and the
Underwriters on the other hand 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 the Company or the Selling Stockholders on the one hand
or the Underwriters on the other hand and the parties' relative intent,
knowledge, access to information and opportunity to correct or prevent such
statement or omission.

         The Sellers and the Underwriters agree that it would not be just and
equitable if contribution pursuant to this Section 8(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 which 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, liabilities or judgments referred to in the
immediately preceding paragraph shall be deemed to include, subject to the
limitations set forth above, any legal or other expenses incurred by such
indemnified party in connection with investigating or defending any matter,
including any action, that could have given rise to such losses, claims,
damages, liabilities or judgments. Notwithstanding the provisions of this
Section 8, no Underwriter shall be required to contribute any amount in excess
of the amount by which the total price at which the Shares underwritten by it






                                      20
<PAGE>   21

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. No
person guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the Act) shall be entitled to contribution from any person who was not
guilty of such fraudulent misrepresentation. The Underwriters' obligations to
contribute pursuant to this Section 8(d) are several in proportion to the
respective number of Shares purchased by each of the Underwriters hereunder and
not joint.

          (e) The remedies provided for in this Section 8 are not exclusive and
shall not limit any rights or remedies which may otherwise be available to any
indemnified party at law or in equity.

          (f) Each Selling Stockholder hereby designates EMCORE Corporation,
394 Elizabeth Avenue, Somerset, New Jersey, 08873, as its authorized agent,
upon which process may be served in any action which may be instituted in any
state or federal court in the State of New York by any Underwriter, any
director or officer of any Underwriter or any person controlling any
Underwriter asserting a claim for indemnification or contribution under or
pursuant to this Section 8, and each Selling Stockholder will accept the
jurisdiction of such court in such action, and waives, to the fullest extent
permitted by applicable law, any defense based upon lack of personal
jurisdiction or venue. A copy of any such process shall be sent or given to
such Selling Stockholder, at the address for notices specified in Section 12
hereof.

         SECTION 9. CONDITIONS OF UNDERWRITERS' OBLIGATIONS. The several
obligations of the Underwriters to purchase the Firm Shares under this
Agreement are subject to the satisfaction of each of the following conditions:

          (a) All the representations and warranties of the Company contained
in this Agreement shall be true and correct on the Closing Date with the same
force and effect as if made on and as of the Closing Date.

          (b) If the Company is required to file a Rule 462(b) Registration
Statement after the effectiveness of this Agreement, such Rule 462(b)
Registration Statement shall have become effective by 10:00 P.M., New York City
time, on the date of this Agreement; and no stop order suspending the
effectiveness of the Registration Statement shall have been issued and no
proceedings for that purpose shall have been commenced or shall be pending
before or contemplated by the Commission.

capacities as the President and Chief Executive Officer and Vice President -
Finance, Chief Financial Officer and Secretary of the Company, confirming the
matters set forth in Sections 6(t), 9(a) and 9(b) and that the Company has
complied with all of the agreements and satisfied all of the conditions herein
contained and required to be complied with or satisfied by the Company on or
prior to the Closing Date.

involving a prospective change in the capital stock or in the long-term debt of

its subsidiaries shall have incurred any liability or obligation, direct or
contingent, the effect of which, in any such case described in clause 9(d)(i),
9(d)(ii) or 9(d)(iii), in your judgment, is material and adverse and, in your
judgment, makes it impracticable to market the Shares on the terms and in the
manner contemplated in the Prospectus.

Stockholder contained in this Agreement shall be true and correct on the
Closing Date with the same force and effect as if made on and as of the Closing

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

         SECTION 10. EFFECTIVENESS OF AGREEMENT AND TERMINATION. This Agreement
shall become effective upon the execution and delivery of this Agreement by the
parties hereto.

         This Agreement may be terminated at any time on or prior to the
Closing Date by you by written notice to the Sellers if any of the following
has occurred: (i) any outbreak or escalation of hostilities or other national
or international calamity or crisis or change in economic conditions or in the
financial markets of the United States or elsewhere that, in your judgment, is
material and adverse and, in your judgment, makes it impracticable to market
the Shares on the terms and in the manner contemplated in the Prospectus, (ii)
the suspension or material limitation of trading in securities or other
instruments on the New York Stock Exchange, the American Stock Exchange, the
Chicago Board of Options Exchange, the Chicago Mercantile Exchange, the Chicago
Board of Trade or the Nasdaq National Market or limitation on prices for
securities or other instruments on any such exchange or the Nasdaq National
Market, (iii) the suspension of trading of any securities of the Company on any
exchange or in the over-the-counter market, (iv) the enactment, publication,
decree or other promulgation of any federal or state statute, regulation, rule
or order of any court or other governmental authority which in your opinion
materially and adversely affects, or will materially and adversely affect, the
business, prospects, financial condition or results of operations of the
Company and its subsidiaries, taken as a whole, (v) the declaration of a
banking moratorium by either federal or New York State authorities or (vi) the
taking of any action by any federal, state or local government or agency in
respect of its monetary or fiscal affairs which in your opinion has a material
adverse effect on the financial markets in the United States.

         If on the Closing Date or on an Option Closing Date, as the case may
be, any one or more of the Underwriters shall fail or refuse to purchase the
Firm Shares or Additional Shares, as the case may be, which it has or they have
agreed to purchase hereunder on such date and the aggregate number of Firm
Shares or Additional Shares, as the case may be, which such defaulting
Underwriter or Underwriters agreed but failed or refused to purchase is not
more than one-tenth of the total number of Firm Shares or Additional Shares, as
the case may be, to be purchased on such date by all Underwriters, each
non-defaulting Underwriter shall be obligated severally, in the proportion
which the number of Firm Shares set forth opposite its name in Schedule I bears
to the total number of Firm Shares which all the non-defaulting Underwriters
have agreed to purchase, or in such other proportion as you may specify, to
purchase the Firm Shares or Additional Shares, as the case may be, which such
defaulting Underwriter or Underwriters agreed but failed or refused to purchase
on such date; PROVIDED that in no event shall the number of Firm Shares or





                                      30
<PAGE>   31

Additional Shares, as the case may be, which any Underwriter has agreed to
purchase pursuant to Section 2 hereof be increased pursuant to this Section 10
by an amount in excess of one-ninth of such number of Firm Shares or Additional
Shares, as the case may be, without the written consent of such Underwriter. If
on the Closing Date any Underwriter or Underwriters shall fail or refuse to
purchase Firm Shares and the aggregate number of Firm Shares with respect to
which such default occurs is more than one-tenth of the aggregate number of
Firm Shares to be purchased by all Underwriters and arrangements satisfactory
to you, the Company and the Selling Stockholders for purchase of such Firm
Shares are not made within 48 hours after such default, this Agreement will
terminate without liability on the part of any non-defaulting Underwriter, the
Company or the Selling Stockholders. In any such case which does not result in
termination of this Agreement, either you or the Sellers shall have the right
to postpone the Closing Date, but in no event for longer than seven days, in
order that the required changes, if any, in the Registration Statement and the
Prospectus or any other documents or arrangements may be effected. If, on an
Option Closing Date, any Underwriter or Underwriters shall fail or refuse to
purchase Additional Shares and the aggregate number of Additional Shares with
respect to which such default occurs is more than one-tenth of the aggregate
number of Additional Shares to be purchased on such date, the non-defaulting
Underwriters shall have the option to (i) terminate their obligation hereunder
to purchase such Additional Shares or (ii) purchase not less than the number of
Additional Shares that such non-defaulting Underwriters would have been
obligated to purchase on such date in the absence of such default. Any action
taken under this paragraph shall not relieve any defaulting Underwriter from
liability in respect of any default of any such Underwriter under this
Agreement.

         SECTION 11. AGREEMENTS OF THE SELLING STOCKHOLDERS. Each Selling
Stockholder agrees with you and the Company:

          (a) To pay or to cause to be paid all transfer taxes payable in
connection with the transfer of the Shares to be sold by such Selling
Stockholder to the Underwriters.

          (b) To do and perform all things to be done and performed by such
Selling Stockholder under this Agreement prior to the Closing Date and to
satisfy all conditions precedent to the delivery of the Shares to be sold by
such Selling Stockholder pursuant to this Agreement.

         SECTION 12. MISCELLANEOUS. Notices given pursuant to any provision of
this Agreement shall be addressed as follows: (i) if to the Company, to EMCORE
Corporation, 394 Elizabeth Avenue, Somerset, New Jersey, 08873, (ii) if to the
Selling Stockholders, to [American Stock Transfer & Trust Co.] c/o [ADDRESS OF

warranties and other statements of the Company, the Selling Stockholders and
the several Underwriters set forth in or made pursuant to this Agreement shall
remain operative and in full force and effect, and will survive delivery of and

Company, any Selling Stockholder or any person controlling such Selling
Stockholder, (ii) acceptance of the Shares and payment for them hereunder and
(iii) termination of this Agreement.

Seller as provided herein (other than as a result of any termination of this
Agreement pursuant to Section 10), the Sellers agree, jointly and severally, to
reimburse the several Underwriters for all out-of-pocket expenses (including
the fees and disbursements of counsel) incurred by them. Notwithstanding any
termination of this Agreement, the Company shall be liable for all expenses
which it has agreed to pay pursuant to Section 5(i) hereof. The Sellers also
agree, jointly and severally, to reimburse the several Underwriters, their
directors and officers and any persons controlling any of the Underwriters for
any and all fees and expenses (including, without limitation, the fees
disbursements of counsel) incurred by them in connection with enforcing their
rights hereunder (including, without limitation, pursuant to Section 8 hereof).

         Except as otherwise provided, this Agreement has been and is made

controlling persons referred to herein, the Company's directors and the
Company's officers who sign the Registration Statement and their respective
successors and assigns, all as and to the extent provided in this Agreement,
and no other person shall acquire or have any right under or by virtue of this
Agreement. The term "successors and assigns" shall not include a purchaser of
any of the Shares from any of the several Underwriters merely because of such
purchase.

         This Agreement shall be governed and construed in accordance with the
laws of the State of New York.

         This Agreement may be signed in various counterparts which together
shall constitute one and the same instrument.

Emcore Corporation Company

Re:  EMCORE Corporation
     Public offering of shares of Common Stock

Ladies and Gentlemen:

         On the date hereof EMCORE Corporation, a New Jersey corporation (the
"Company"), filed with the Securities and Exchange Commission under the
Securities Act of 1933, as amended (No. 333-71791) a Registration Statement on
Form S-3 (the "Registration Statement"). Such Registration Statement relates to
the sale by the Company of up to 3,584,616 shares of the Company's Common Stock,
no par value per share (the "Common Stock") and 897,441 shares of Common Stock
by selling shareholders.

         We have acted as counsel to the Company in connection with the
preparation of the Registration Statement. We are familiar with the proceedings
of the Board of Directors of the Company in connection with the authorization,
issuance and sale of the Shares. We have examined such certificates of public
officials and certificates of officers of the Company and the selling
shareholders, and the originals (or copies thereof, certified to our
satisfaction) of such corporate documents and records of the Company, and such
other documents, records and papers as we have deemed relevant in order to give
the opinions hereinafter set forth. In this connection, we have assumed the
genuineness of signatures, the authenticity of all documents submitted to us as



<PAGE>   2



Page 2

originals and the conformity to authentic original documents of all documents
submitted to us as certified, conformed, facsimile or photostatic copies. In
addition, we have relied, to the extent that we deem such reliance proper, upon
such certificates of public officials and of officers of the Company with
respect to the accuracy of material factual matters contained therein which
were not independently established.

         We do not express or purport to express any opinions with respect to
laws other than the Federal laws of the United States. As to all matters
governed by the laws of the State of New Jersey involved in our opinions set
forth below, we have relied, with your consent, upon an opinion of Dillon Bitar
& Luther dated today and addressed to us.

         Based upon the foregoing, we are of the opinion that the Shares have
been duly authorized and, when issued and delivered by the Company against
payment therefor as provided by the Underwriting Agreement will be validly
issued, fully paid and non-assessable, and may be issued free of restrictive
legends.

         We hereby consent to the filing of this opinon as an exhibit to the
Registration Statement and to the use of our name under the caption "Legal
Matters" in the Prospectus forming a part of the Registration Statement.


                                              Very truly yours,


                                              White & Case LLP

                              AMENDED AND RESTATED
                                 PROMISSORY NOTE
                           (REVOLVING LINE OF CREDIT)

$19,000,000.00

                                                                  April 29, 1999

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

FIRST UNION NATIONAL BANK
190 River Road
Summit, New Jersey 07901
(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 NINETEEN MILLION AND NO/100 DOLLARS ($19,000,000.00) 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").

AMENDED AND RESTATED NOTE. This Note shall be deemed to replace and supercede
the $8,000,000 Promissory Note (Revolving Line of Credit) dated June 22, 1998
and the $5,000,000 Promissory Note (Revolving Line of Credit dated January 29,
1999, in each case made by Borrower and payable to the Bank (the "Prior Notes").
Accordingly, as of the date hereof, all of Borrower's obligations evidenced by
the Prior Notes shall be deemed to be evidenced by this Note and all of the
terms and conditions of the Prior Notes are amended and restated in their
entirety by the terms and conditions of this Note. It is hereby acknowledge that
the terms and conditions of this Note that pertain to Borrower's obligations
under the Prior Notes are a modification of said obligations under the Prior
Notes, and not an extinguishment, satisfaction or novation of such obligations.

SECURITY. This Note is secured by, INTER ALIA, 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 "Interest
Period" means, initially, the period commencing on the date hereof and ending
April 30, 1999, and thereafter, each period commencing on the last day of the
immediately preceding Interest Period 





<PAGE>   2

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 (as 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 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.




                                       2
<PAGE>   3

REPAYMENT TERMS. This Note shall be due and payable in consecutive monthly
payments of accrued interest only commencing on April 30, 1999, and on the last
day of each one month Interest Period occurring 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) October 1, 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, be applied Borrower will prepay the Obligations in an amount
equal to 100% of such Net Cash Proceeds (or that portion of such proceeds
required to so prepay said Obligations), and (notwithstanding any provision of
this Note or any other Loan Document) such prepayment shall be applied in the
following manner:

                  FIRST: to prepay the principal balance of any outstanding
                  Revolving Loans (defined herein), together with any accrued
                  and unpaid interest thereon, and
                  SECOND: to prepay 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 such 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 or 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, 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 under 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

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.

if for any reason the effective interest should exceed the maximum lawful
interest, 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.

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

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

U.S.C. Section 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

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

by Note Guarantor in the Guaranty or any other Loan Document to which it is a

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.

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

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.

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 amended by (i) the Consent and Amendment thereto dated December 5, 1997,
(ii) the Second Amendment thereto dated as of November 30, 1998, and (iii) the
letter waiver and amendment dated March 8, 1999 (such agreement, as so amended
and as the same may be further amended from time to time in the future, 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 (i) 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 and (ii) the Obligations hereunder shall be
secured, guaranteed and otherwise supported by the Loan Documents and Collateral
referred to therein.

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 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

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

by and construed under the laws of the state where Bank first shown above is

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

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

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

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

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.

Borrower and Bank agree that they shall not have a remedy of punitive or
exemplary damages against the other in any Dispute and hereby waive any right or
claim to punitive or exemplary damages they have now or which may arise in the
future in connection with any Dispute whether the Dispute is resolved by
arbitration or judicially.

no Revolving Loans shall be made hereunder until the Bank has received the
following:

      (1)  This Note, duly executed and delivered by the Borrower;

      (3)  Each of the other documents and materials itemized on the Closing

         7. RETURN OF UNDELIVERED SHARES. If the Shares are not accepted by the
Underwriters against payment therefor in accordance with the terms and
provisions of the Underwriting Agreement, or if the Underwriting Agreement
shall be otherwise terminated pursuant to the provisions thereof, the Custodian
shall return to the undersigned the certificate(s) referred to in Section 2(b)
of this Agreement and held by it for the account of the undersigned hereunder.

         8. MISCELLANEOUS. This Agreement may be executed in any number of
counterparts each of which shall be deemed to be an original and all of which
