                               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, 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>   9

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>   10

     - 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 four joint ventures (with Optek
Technology, Inc., Union Miniere, Inc., Uniroyal Technology Corporation and
General Electric Lighting). 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.

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 44.5% 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>   12

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>   13

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>   14

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>   15

     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>   16

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 13,239,227 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 1,225,511 shares
of our common stock, warrants to purchase 1,878,265 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

                                       16
<PAGE>   17

venture with General Electric Lighting, we have issued 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 is
convertible into 340,984 shares of common stock at a conversion price equal to
$22 7/8.

     Certain shareholders, representing approximately 6,863,579 shares of our
common stock (including shares of common stock issuable upon conversion of our
convertible preferred stock, convertible debenture 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 $52.8 million ($63.2 million
if the underwriters' over-allotment option is exercised in full), assuming a
public offering price of $19.00 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:

</TABLE>

     When the debt is extinguished, there will be an extraordinary charge in
1999 of approximately $1.3 million 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.

     The reported last sale price of the common stock on the Nasdaq National
Market on June 10, 1999 was $19 9/16 per share. As of May 1, 1999, EMCORE had
approximately 1,742 shareholders of record.

     EMCORE has not declared or paid dividends on its common stock since its
formation. EMCORE currently does not intend to pay dividends on its common stock
in the foreseeable future so that it may reinvest its earnings in its business.
The shares of EMCORE's convertible preferred stock are entitled to receive
cumulative quarterly dividends at the annual rate of 2% of their liquidation
preference ($0.28 per annum per share). The payment of dividends, if any, on the
common stock in the future will be at the discretion of EMCORE's board of
directors.

                                 CAPITALIZATION

     The following table sets forth the capitalization of EMCORE as of March 31,
1999, and as adjusted to reflect the sale by EMCORE of 3,000,000 shares of
common stock being offered hereby (at an offering price of $19.00 per share),
the conversion of 520,000 shares of convertible preferred stock into 520,000
shares of common stock and the exercise of 19,898 warrants at $4.08 per share
and 186,030 warrants at $10.20 per share into 205,928 shares of common stock and
the application of the estimated net proceeds therefrom. The as adjusted March
31, 1999 amounts also reflect actual share issuances between March 31, 1999 and
May 1, 1999 and the extraordinary loss that would have been recorded at March
31, 1999 upon repayment of long-term debt with the offering proceeds.

                      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>   24

     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 the last week of May 1999, EMCORE and General Electric Lighting formed
       GELcore, a joint venture to develop and market white light and colored HB
       LED lighting products. GELcore's long-term goal is to develop HB LED
       products to replace traditional lighting. We invested $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 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 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 germanium. EMCORE has invested $600,000 in UMCore which,
       together with

                                       24
<PAGE>   25

       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 months of fiscal 1999, international sales constituted 42.5%, 42.0%,
39.1% and 44.5%,

                                       25
<PAGE>   26

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 44.5% of revenues for the six months ended March 31, 1999.

                                       27
<PAGE>   28

     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 $1.2 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 $1.2 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>   29

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>   30

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 $13.2 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>   31

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

                                       31
<PAGE>   32

was utilized. EMCORE has capitalized approximately $0.5 million for MODE's
workforce, which is included in goodwill and is offset against the values
assigned in the table above.

     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 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

                                       32
<PAGE>   33

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.

     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 $13.7 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.

                                       33
<PAGE>   34

     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 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.

                                       34
<PAGE>   35

     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>   37

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>   38

     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.

     In connection with the GELcore joint venture, EMCORE issued 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 purchased a
$7.8 million subordinated convertible debenture bearing interest at 4.75% per
annum and maturing in 2006. The debenture's interest rate is subject to
adjustment in the event EMCORE does not complete a public offering by June 30,
1999. The debenture is convertible into 340,984 shares of common stock at a
conversion price equal to $22.875. Proceeds from the debenture were 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 Rockwell a royalty including interest under our license agreement relating
to

                                       38
<PAGE>   39

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. Management
has reviewed and reassessed the royalty agreements and concluded that it has the
appropriate amounts reserved for at both September 30, 1998 and March 31, 1999.
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>   40

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>   41

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
communica-

                                       42
<PAGE>   43

tions, data communications, telecommunications, wireless communications,

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>   45

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>   46

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>   47

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>   48

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 May 1999, EMCORE and General Electric Lighting formed 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 compound
semiconductor production systems with General Electric Lighting's brand name
recognition

                                       51
<PAGE>   52

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.

     In May 1999, Sumitomo Electric and EMCORE announced a long-term agreement
to jointly develop and produce certain RF materials for use in digital

                                       52
<PAGE>   53

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 sample volumes of materials commenced 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 Taiwan and California in order to be closer to its customers. As of
March 31, 1999, EMCORE employed 26 persons in sales and marketing.

                                       53
<PAGE>   54

     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
<PAGE>   56

     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. Management has reviewed and reassessed the
royalty agreements and concluded that it has the appropriate amounts reserved
for at both September 30, 1998 and March 31, 1999. Additionally, 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>   57

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>   58

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

     In the last week of May 1999, EMCORE and General Electric Lighting formed a
joint venture to develop and market HB LED lighting products. In connection with
consummation of this joint venture, EMCORE issued to General Electric warrants
to purchase 282,010 shares of EMCORE common stock, which will expire in 2006 and
have an exercise price of $22.875. In addition, General Electric purchased a
$7.8 million subordinated convertible debenture bearing interest at 4.75% per
annum and maturing in 2006. The debenture is convertible into 340,984 shares of
common stock at General Electric's option.

     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.

     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.

</TABLE>

     The underwriting agreement provides that the obligations of the several
underwriters to purchase and accept delivery of the shares of common stock
offered hereby are subject to approval by their counsel of certain legal matters
and certain other conditions. The underwriters are obligated to purchase and
accept delivery of all the shares of common stock offered hereby (other than
those shares covered by the over-allotment option described below) if any are
purchased.

     The underwriters initially propose to offer the shares of common stock in
part directly to the public at the public offering price set forth on the cover
page of this prospectus and in part to certain dealers (including the
underwriters) at such price less a concession not in excess of $0.68 per share.
The underwriters may allow, and such dealers may re-allow, to certain other
dealers a concession not in excess of $0.10 per share. After the initial
offering of the common stock, the public offering price and other selling terms
may be changed by the representatives at any time without notice.

     DLJdirect Inc., an affiliate of Donaldson, Lufkin & Jenrette Securities
Corporation and a member of the selling group, is facilitating the distribution
of the shares sold in the offering over the Internet. The underwriters have
agreed to allocate a limited number of shares to DLJdirect Inc. for sale to its
brokerage account holders.

     EMCORE has granted to the underwriters an option, exercisable within 30
days after the date of this prospectus, to purchase, from time to time, in whole
or in part, up to an aggregate of 584,616 additional shares of common stock at
the public offering price less underwriting discounts and commissions. The
underwriters may exercise such option solely to cover over-allotments, if any,
made in connection with this offering. To the extent that the underwriters
exercise such option, each underwriter will become obligated, subject to certain
conditions, to purchase its pro rata portion of such additional shares based on
such underwriter's percentage underwriting commitment as indicated in the
preceding table.

     EMCORE and the selling shareholders have agreed to indemnify the
underwriters against certain liabilities, including liabilities under the
Securities Act of 1933, or to contribute to payments that the underwriters may
be required to make in respect thereof.

                                       68

     Each of EMCORE, its executive officers and directors and certain
shareholders of EMCORE (including the selling shareholders) has agreed, subject
to certain exceptions, not to (i) offer, pledge, sell, contract to sell, sell
any option or contract to purchase, purchase any option or contract to sell,
grant any option, right or warrant to purchase or otherwise transfer or dispose
of, directly or indirectly, any shares of common stock or (ii) enter into any
swap or other arrangement that transfers all or a portion of the economic
consequences associated with the ownership of any common stock (regardless of
whether any of the transactions described in clause (i) or (ii) is to be settled
by the delivery of common stock, or such other securities, in cash or otherwise)
for a period of 90 days after the date of the prospectus without the prior
written consent of Donaldson, Lufkin & Jenrette. In addition, during such
period, EMCORE has also agreed not to file any registration statement with
respect to, and each of its executive officers, directors and certain
shareholders of EMCORE (including the selling shareholders) has agreed not to
make any demand for, or exercise any right with respect to, the registration of
any shares of common stock or any securities convertible into or exercisable or
exchangeable for common stock without the prior written consent of Donaldson,
Lufkin & Jenrette.

     Other than in the United States, no action has been taken by EMCORE, the
selling shareholders or the underwriters that would permit a public offering of
the shares of common stock offered hereby in any jurisdiction where action for
that purpose is required. The shares of common stock offered hereby may not be
offered or sold, directly or indirectly, nor may this prospectus or any other
offering material or advertisements in connection with the offer and sale of any
such shares of common stock be distributed or published in any jurisdiction,
except under circumstances that will result in compliance with the applicable
rules and regulations of such jurisdiction. Persons into whose possession this
prospectus comes are advised to inform themselves about and to observe any
restrictions relating to this offering of the common stock and the distribution
of this prospectus. This prospectus does not constitute an offer to sell or
solicitation of an offer to buy any shares of common stock offered hereby in any
jurisdiction in which such an offer or a solicitation is unlawful.

     The underwriters and dealers may engage in passive market making
transactions in the common stock in accordance with Rule 103 of Regulation M
promulgated by the Commission. In general, a passive market maker may not bid
for or purchase shares of common stock at a price that exceeds the highest
independent bid. In addition, the net daily purchases made by any passive market
maker generally may not exceed 30% of its average daily trading volume in the
common stock during a specified two-month period, or 200 shares, whichever is
greater. A passive maker must identify passive market making bids as such on the
Nasdaq electronic inter-dealer reporting system. Passive market making may
stabilize or maintain the market price of the common stock above independent
market levels. Underwriters and dealers are not required to engage in passive
market making and may end passive market making activities at any time.

     In connection with the offering, the underwriters may engage in
transactions that stabilize, maintain or otherwise affect the price of the
common stock. Specifically, the underwriters may overallot this offering,
creating a syndicate short position. In addition, the underwriters may bid for
and purchase shares of common stock in the open market to cover syndicate short
positions or to stabilize the price of the common stock. Finally, the
underwriting syndicate may reclaim selling concessions from

                                       69
<PAGE>   70

syndicate members in the offering, if the syndicate repurchases previously
distributed common stock in syndicate covering transactions, in stabilization
transactions or otherwise. Any of these activities may stabilize or maintain the
market price of the common stock above independent market levels. The
underwriters are not required to engage in these activities, and may end any of
these activities at any time.

                                 LEGAL MATTERS

     The consolidated financial statements of EMCORE as of September 30, 1998
and for the year then ended included and incorporated by reference in this
prospectus, have been audited by Deloitte & Touche LLP, independent auditors, as
stated in their report (which expresses an unqualified opinion and includes an
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 of EMCORE 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 and incorporated by reference in this prospectus,
have been included herein and incorporated by reference in reliance on the
report of PricewaterhouseCoopers LLP, independent accountants, given on the
authority of that firm as experts in accounting and auditing.

     The financial statements of MicroOptical Devices, Inc. included in this
prospectus and elsewhere in the registration statement, to the extent and for

LLP, independent public accountants, and are included herein in reliance upon
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.

     The statements in this Prospectus set forth under the captions "Risk
Factors -- Our ability to protect our trade secrets is crucial to our business."

           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>   72

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>   73

    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

                                       F-9

                  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

                                      F-10

                               EMCORE CORPORATION

                  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

                                      F-11
<PAGE>   86
                               EMCORE CORPORATION

                  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>
<S>                                                           <C>
Net tangible assets.........................................  $   156,000
Goodwill....................................................   13,157,000
Acquired in process research and development................   19,516,000
                                                              -----------
  Total purchase price......................................  $32,829,000
                                                              ===========
</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.

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
leases with an initial or remaining term of one year or more as of September 30,
1998 are as follows:

</TABLE>

     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

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)

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

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

NOTE 13.  RELATED PARTIES

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

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

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

been paid in full. As of September 30, 1998, the Company had an outstanding
related party receivable of $500,000.

     In July 1998, the Company and a wholly-owned subsidiary of UTC 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).

or in part, at the option of the Company at any time the Company's stock has
traded at or above $28.00 per share for 30 consecutive trading days, at a price
of $14.00 per share, plus accrued and unpaid dividends, if any, to the
redemption date. The Series I Preferred stock carries a dividend of 2% per
annum. Dividends are being charged to accumulated deficit in the absence of
additional paid in capital. In addition, the Series I Preferred Stock is subject
to mandatory redemption by the Company at $14.00 per share plus accrued and

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

                 FOR THE PERIOD FROM INCEPTION (AUGUST 3, 1995)
                           THROUGH DECEMBER 31, 1996
                    AND FOR THE YEAR ENDED DECEMBER 31, 1996
          AND FOR THE PERIOD FROM INCEPTION THROUGH DECEMBER 31, 1995

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
208,695 shares of MODE's Series B convertible preferred stock, on a post stock
split basis (see Note 5), exercisable at any time for a period of up to ten
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

                                      F-41

                  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
below:

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.

     Keyman Life Insurance.  The Company is beneficiary to $500,000 of term life
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
