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:

o operation at higher speeds;

o lower power consumption;

o less noise and distortion; and

o 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.

We were incorporated in the State of New Jersey in September 1986. Our
principal executive offices are located at 394 Elizabeth Avenue, Somerset, New
Jersey 08873, and our telephone number is (732) 271-9090. You can reach our web

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 December 31, 1999 had an
accumulated deficit of $90.0 million. We incurred net losses of $5.6 million
in fiscal 1997, $36.4 million in fiscal 1998 and $22.7 million in 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.


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 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.

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(R) 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.



2


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:

o we are unable to improve our existing products on a timely basis;

o our new products are not introduced on a timely basis;

o we incur budget overruns or delays in our research and development
efforts; or

o 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:

o the volume and timing of orders for our products, particularly
TurboDisc(R) systems, which have an average selling price in
excess of $1 million;

o the timing of our announcement and introduction of new products
and of similar announcements by our competitors;

o downturns in the market for our customers' products;

o regional economic conditions, particularly in Asia where we derive
a significant portion of our revenues; and

o 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.

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
General Electric Lighting, Uniroyal Technology Corporation, Union Miniere, Inc.,
and Optek Technology, Inc.). 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



3



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 42.0% of our revenues in fiscal 1997, 39.1% of our revenues in
fiscal 1998 and 52.5% of our revenues in 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:

o political and economic instability may inhibit export of our
systems and devices and limit potential customers' access to
dollars;

o shipping and installation costs of our systems may increase;

o 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;

o a strong dollar may make our systems less attractive to foreign
purchasers who may decide to postpone making the capital
expenditure;

o tariffs and other barriers may make our systems and devices less
cost competitive;

o we may have difficulty in staffing and managing our international
operations;

o the laws of certain foreign countries may not adequately protect
our trade secrets and intellectual property; and

o 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. 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 9.7% of our revenues in 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.



4



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(R) 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(R) 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.

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(R) 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(R) 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.

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.




5



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 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.

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.

To manufacture our wafers and devices we try to the greatest extent
possible to rely on our own technology. Occasionally, we are required to obtain
licenses from third parties to manufacture and sell our products. The royalty
payments for these licenses can be expensive and reduce the profits that we
realize from sale of our products. We may be required to pay royalties to
Rockwell International Corporation for certain of our past sales of wafers and
devices to customers who do not hold licenses from Rockwell International
Corporation. 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.

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.

Even though the date is now past January 1, 2000, and we have not
experienced any immediate adverse impact from the transition to the Year 2000,
we cannot provide assurance that our suppliers and customers have not been
affected in a manner that is not yet apparent, and any negative consequential
effects remain unknown. As a result, we will continue to monitor our Year 2000
compliance and the Year 2000 compliance of our suppliers and customers.

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. As of March 1, 2000, they collectively
beneficially owned approximately 23.5% of our common stock. 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.





6



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.

OUR BUSINESS OR OUR STOCK PRICE COULD BE ADVERSELY AFFECTED BY ISSUANCE OF
ADDITIONAL PREFERRED STOCK.

Our board of directors is authorized to issue up to 5,882,352 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 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 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,
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.


The 22,000 shares registered hereunder will become available for resale
in the market without restriction upon effectiveness. Sales of any substantial
number of shares of our common stock in the public market may have an adverse
effect on the market price of our common stock. The average daily trading volume
of our common stock has varied widely. Any sustained sales of shares by our
existing or future shareholder or any increase in the average volume of shares
traded in the public market may adversely affect the market price of our common
stock. There sales also might make it more difficult for us to sell equity or
equity-related securities, including the common stock registered hereunder, in
the future at a time and price that we deem appropriate. The shelf registration
declared effective on October 6, 1999 and this post-effective amendment thereto
will remain effective until November 17, 2003 or such earlier time as all of the
shares of our common stock are no longer restricted under rule 144.


At the present we have a substantial number of shares that are issuable
upon the exercise of outstanding warrants and stock options.

PLAN OF DISTRIBUTION

We are registering the shares offered by the selling shareholders
hereunder pursuant to covenants and contractual registration rights contained in
the Registration Rights Agreement, dated as of May 1, 1996, between EMCORE and
the investors named therein relating to a private placement, the Registration
Rights Agreement, dated as of December 5, 1997, by and among the Company and the
holders named therein relating to the acquisition of MicroOptical Devices, Inc.,
the Registration Rights Agreement, dated November 30, 1998 by and between the
Company, Hakuto, UMI and UTC relating to the purchase of Series I Redeemable
Convertible Preferred Stock, and the Registration Rights Agreement, dated as of
May 26, 1999, by and between the Company and GE Capital Equity Investments,
Inc., relating to the joint venture with General Electric Lighting
(collectively, the "Registration Rights Agreements"). The selling shareholders
may sell all, some or none of the shares of EMCORE common stock offered by this
prospectus from time to time directly to purchasers in one or more transactions.
The selling shareholders will act independently of us in making decisions with
respect to the timing, manner and size of each sale. Sales may be made on the
Nasdaq National Market or in private transactions or in a combination of such
methods of sale. Such transactions may be at a fixed price, which may be
changed, or at varying prices determined at the time of sale or at negotiated
prices. Such prices will be determined by the holders of such securities or by
agreement between such holders and underwriters or dealers who may receive fees
of commissions in connection therewith.

Any of the selling shareholders may from time to time offer shares of
EMCORE common stock beneficially owned by them through underwriters, dealers or
agents, who may receive compensation in the form of underwriting discounts,
commissions or concessions from the selling shareholders and the purchasers of
the shares for whom they may act as agent. Each selling shareholder will be
responsible for payment of commissions, concessions and discounts of
underwriters, dealers or agents. The aggregate proceeds of the selling
shareholders from the sale of the shares of EMCORE common stock offered by them
will be the purchase price of such shares less discounts and commissions, if
any. Each of the selling shareholders reserves the right to accept and, together
with their agents from time to time to reject, in whole or in part, any proposed
purchase of shares to be made directly or through agents. We will not receive
any of the proceeds from this offering. Alternatively, the selling shareholders
may sell all or a portion of the shares of EMCORE common stock beneficially
owned by them and offered hereby from time to time on any exchange on which the
securities are listed on terms to be determined at the times of such sales. The
selling shareholders may also make private sales directly or through a broker or
brokers. Transactions through broker-dealers may, including block trades in
which brokers or dealers will attempt to sell the shares of EMCORE common stock
as agent but may position and resell the block as principal to facilitate the
transaction, or one or more underwritten offerings on a firm commitment or best
effort basis.

From time to time, the selling shareholders may transfer, pledge,
distribute, donate or assign shares of EMCORE common stock to lenders or others
and each of such persons will be deemed to be a "selling shareholder" for
purposes of the prospectus. The number of the selling shareholders' shares
beneficially owned by a selling shareholder who transfers, pledges, distributes
donates or assigns shares of EMCORE common stock will decrease as and when they
take such actions. The plan of distribution for selling shareholders' shares
sold hereunder will otherwise remain unchanged, except that the transferees,
pledgees, distributees, donees or other successors will be selling shareholders
hereunder.

A selling shareholder may enter into hedging transactions with
broker-dealers, and the broker-dealers may engage in short sales of the shares
of EMCORE common stock in the course of hedging the positions they assume with
such selling shareholder, including, without limitation, in connection with
distribution of the shares of EMCORE common stock by such broker-dealers. In
addition, the selling shareholder may, from time to time, sell short the shares
of EMCORE common stock, and in such instances, this prospectus may be delivered
in connection with such short sales and the shares offered hereby may be used to
cover such short sales. The selling shareholders may also enter into option or
other transactions with broker-dealers that involve the delivery of the shares
of EMCORE common stock to the broker-dealers, who may then resell or otherwise
transfer such shares. The selling shareholders may also loan or pledge the
shares to a broker-dealer and the broker-dealer may sell the shares as loaned or
upon a default may sell or otherwise transfer the pledge shares.

The selling shareholders and any underwriters, dealers or agents that
participate in the distribution of the shares of EMCORE common stock offered
hereby may be deemed to be underwriters within the meaning of the Securities Act
of 1933 (the "Securities Act"), and any discounts, commissions or concessions
received by them and any provided pursuant to the sale of shares by them might
be deemed to be underwriting discounts and commissions under the Securities Act.




10



In addition, any securities covered by this prospectus which qualify
for sale pursuant to Rule 144 of the Securities Act may be sold under Rule 144
rather than pursuant to this prospectus. There is no assurance that any selling
shareholder will sell any or all of the shares of EMCORE common stock described
herein, and any selling shareholder may transfer, devise or gift such securities
by other means not described herein.

In order to comply with the securities laws of certain states, if
applicable, the shares may only be sold in such jurisdictions through registered
or licensed brokers or dealers. In addition, in certain states the shares may
not be sold unless they have been registered or qualified for sale in the
applicable state or an exemption from the registration or qualification
requirement is available and is complied with.

The selling shareholders may be subject to the anti-manipulation rules
of Regulation M under the Securities Exchange Act of 1934 which apply to sales
of shares in the market and to the activities of the selling security holders
and their affiliates. We will make copies of this prospectus, with any
supplements or amendments, available to the selling shareholders for delivery to
purchasers at or prior to the time of any sale of the shares offered herewith.
The selling shareholders may indemnify any broker-dealer that participates in
transactions involving the sale of the shares against liabilities resulting
therefrom. Among these liabilities for which indemnification may be provided are
those arising under the Securities Act of 1933.


Pursuant to Registration Rights Agreements, we have agreed to indemnify
the selling shareholders against certain liabilities, including certain
liabilities under the Securities Act of 1933. We have also agreed to pay the
expenses of registering all of the shares of common stock offered hereby under
the Securities Act of 19333, including all registration, filing and exchange
listing fees, blue sky expenses, fees of counsel and accountants, fees of the
NASD, transfer taxes, if any, transfer agent fees and underwriters' fees
customarily paid by issuers (excluding underwriting discounts and commissions).
Such expenses are estimated to be $16,592. The Registration Rights Agreements
require us to maintain the effectiveness of the registration statement, as
amended or supplemented from time to time, relating to this prospectus until the
earlier of:


o The date on which all of the shares offered by this prospectus are
resold by the selling shareholders;

o The date on which all of the shares of our convertible preferred
stock and the common stock issued upon conversion thereof offered
by this prospectus are no longer restricted under Rule 144 are
resold by the selling security holders; and

o November 17, 2003.

We intend to de-register the shares covered by this prospectus that are
not sold by the selling shareholders within the above time frame.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS

EMCORE's Restated Certificate of Incorporation provides that the
Company shall indemnify its directors and officers to the full extent permitted
by New Jersey law, including in circumstances in which indemnification is
otherwise discretionary under New Jersey law.

Section 14A:2-7 of the New Jersey Business Corporation Act provides
that a New Jersey corporation's:

"certificate of incorporation may provide that a director or officer
shall not be personally liable, or shall be liable only to the extent therein
provided, to the corporation or its shareholders for damages for breach of any
duty owed to the corporation or its shareholders, except that such provision
shall not relieve a director or officer from liability for any breach of duty
based upon an act or omission (a) in breach of such person's duty of loyalty to
the corporation or its shareholders, (b) not in good faith or involving a
knowing violation of law or (c) resulting in receipt by such person of an
improper personal benefit. As used in this subsection, an act or omission in
breach of a person's duty of loyalty means an act or omission which that person
knows or believes to be contrary to the best interests of the corporation or its
shareholders in connection with a matter in which he has a material conflict of
interest."

In addition, Section 14A:3-5 (1995) of the New Jersey Business Corporation Act
(1995) provides as follows:

INDEMNIFICATION OF DIRECTORS, OFFICERS AND EMPLOYEES

(1) As used in this section,

(a) "Corporate agent" means any person who is or was a
director, officer, employee or agent of the indemnifying corporation or
of any constituent corporation absorbed by the indemnifying corporation
in a consolidation or merger and any person who is or was a director,
officer, trustee, employee or agent of any other enterprise, serving as
such at the request of the indemnifying corporation, or of any such
constituent corporation, or the legal representative of any such
director, officer, trustee, employee or agent;

(b) "Other enterprise" means any domestic or foreign
corporation, other than the indemnifying corporation, and any
partnership, joint venture, sole proprietorship, trust or other
enterprise, whether or not for profit, served by a corporate agent;




15


(c) "Expenses" means reasonable costs, disbursements and
counsel fees;

(d) "Liabilities" means amounts paid or incurred in
satisfaction of settlements, judgments, fines and penalties;

(e) "Proceeding" means any pending, threatened or completed
civil, criminal, administrative or arbitrative action, suit or
proceeding, and any appeal therein and any inquiry or investigation
which could lead to such action, suit or proceeding; and

(f) References to "other enterprises" include employee benefit
plans; references to "fines" include any excise taxes assessed on a
person with respect to an employee benefit plan; and references to
"serving at the request of the indemnifying corporation" include any
service as a corporate agent which imposes duties on, or involves
services by, the corporate agent with respect to an employee benefit
plan, its participants, or beneficiaries; and a person who acted in
good faith and in a manner the person reasonably believed to be in the
interest of the participants and beneficiaries of an employee benefit
plan shall be deemed to have acted in a manner "not opposed to the best
interests of the corporation" as referred to in this section.

(2) Any corporation organized for any purpose under any general or
special law of this State shall have the power to indemnify a corporate agent
against his expenses and liabilities in connection with any proceeding involving
the corporate agent by reason of his being or having been such a corporate
agent, other than a proceeding by or in the right of the corporation, if

(a) such corporate agent acted in good faith and in a manner
he reasonably believed to be in or not opposed to the best interests of
the corporation; and

(b) with respect to any criminal proceeding, such corporate
agent had no reasonable cause to believe his conduct was unlawful. The
termination of any proceeding by judgment, order, settlement,
conviction or upon a plea of nolo contendere or its equivalent, shall
not of itself create a presumption that such corporate agent did not
meet the applicable standards of conduct set forth in paragraphs
14A:3-5(2)(a) and 14A:3-5(2)(b).

(3) Any corporation organized for any purpose under any general or
special law of this State shall have the power to indemnify a corporate agent
against his expenses in connection with any proceeding by or in the right of the
corporation to procure a judgment in its favor which involves the corporate
agent by reason of his being or having been such corporate agent, if he acted in
good faith and in a manner he reasonably believed to be in or not opposed to the
best interests of the corporation. However, in such proceeding no
indemnification shall be provided in respect of any claim, issue or matter as to
which such corporate agent shall have been adjudged to be liable to the
corporation, unless and only to the extent that the Superior Court or the court
in which such proceeding was brought shall determine upon application that
despite the adjudication of liability, but in view of all circumstances of the
case, such corporate agent is fairly and reasonably entitled to indemnity for
such expenses as the Superior Court or such other court shall deem proper.

(4) Any corporation organized for any purpose under any general or
special law of this State shall indemnify a corporate agent against expenses to
the extent that such corporate agent has been successful on the merits or
otherwise in any proceeding referred to in subsections 14A:3-5(2) and 14A:3-5(3)
or in defense of any claim, issue or matter therein.

(5) Any indemnification under subsection 14A:3-5(2) and, unless ordered
by a court, under subsection 14A:3-5(3) may be made by the corporation only as
authorized in a specific case upon a determination that indemnification is
proper in the circumstances because the corporate agent met the applicable
standard of conduct set forth in subsection 14A:3-5(2) or subsection 14A:3-5(3).
Unless otherwise provided in the certificate of incorporation or bylaws, such
determination shall be made.

(a) by the board of directors or a committee thereof, acting
by a majority vote of a quorum consisting of directors who were not
parties to or otherwise involved in the proceeding; or

(b) if such a quorum is not obtainable, or, even if obtainable
and such quorum of the board of directors or committee by a majority
vote of the disinterested directors so directs, by independent legal
counsel, in a written opinion, such counsel to be designated by the
board of directors; or



16


(c) by the shareholders if the certificate of incorporation or
bylaws or a resolution of the board of directors or of the shareholders
so directs.

(6) Expenses incurred by a corporate agent in connection with a
proceeding may be paid by the corporation in advance of the final disposition of
the proceeding as authorized by the board of directors upon receipt of an
undertaking by or on behalf of the corporate agent to repay such amount if it
shall ultimately be determined that he is not entitled to be indemnified as
provided in this section.

(7)(a) If a corporation upon application of a corporate agent has
failed or refused to provide indemnification as required under subsection
14A:3-5(4) or permitted under subsections 14A:3-5(2), 14A:3-5(3) and 14A:3-5(6),
a corporate agent may apply to a court for an award of indemnification by the
corporation, and such court

(i) may award indemnification to the extent authorized under
subsections 14A:3-5(2) and 14A:3-5(3) and shall award indemnification
to the extent required under subsection 14A:3-5(4), notwithstanding any
contrary determination which may have been made under subsection
14A:3-5(5); and

(ii) may allow reasonable expenses to the extent authorized
by, and subject to the provisions of, subsection 14A:3-5(6), if the
court shall find that the corporate agent has by his pleadings or
during the course of the proceeding raised genuine issues of fact or
law.

(b) Application for such indemnification may be made:

(i) in the civil action in which the expenses were or are to
be incurred or other amounts were or are to be paid; or

(ii) to the Superior Court in a separate proceeding. If the
application is for indemnification arising out of a civil action, it
shall set forth reasonable cause for the failure to make application
for such relief in the action or proceeding in which the expenses were
or are to be incurred or other amounts were or are to be paid.

The application shall set forth the disposition of any previous
application for indemnification and shall be made in such manner and form as may
be required by the applicable rules of court or, in the absence thereof, by
direction of the court to which it is made. Such application shall be upon
notice to the corporation. The court may also direct that notice shall be given
at the expense of the corporation to the shareholders and such other persons as
it may designate in such manner as it may require.

(8) The indemnification and advancement of expenses provided by or
granted pursuant to the other subsections of this section shall not exclude any
other rights, including the right to be indemnified against liabilities and
expenses incurred in proceedings by or in the right of the corporation, to which
a corporate agent may be entitled under a certificate of incorporation, bylaw,
agreement, vote of shareholders, or otherwise; provided that no indemnification
shall be made to or on behalf of a corporate agent if a judgment or other final
adjudication adverse to the corporate agent establishes that his acts or
omissions (a) were in breach of his duty of loyalty to the corporation or its
shareholders, as defined in subsection (3) of N.J.S.14A:2-7, (b) were not in
good faith or involved a knowing violation of law or (c) resulted in receipt by
the corporate agent of an improper personal benefit.

(9) Any corporation organized for any purpose under any general or
special law of this State shall have the power to purchase and maintain
insurance on behalf of any corporate agent against any expenses incurred in any
proceeding and any liabilities asserted against him by reason of his being or
having been a corporate agent, whether or not the corporation would have the
power to indemnify him against such expenses and liabilities under the
provisions of this section. The corporation may purchase such insurance from, or
such insurance may be reinsured in whole or in part by, an insurer owned by or
otherwise affiliated with the corporation, whether or not such insurer does
business with other insureds.

(10) The powers granted by this section may be exercised by the
corporation, notwithstanding the absence of any provision in its certificate of
incorporation or bylaws authorizing the exercise of such powers.



17


(11) Except as required by subsection 14A:3-5(4), no indemnification
shall be made or expenses advanced by a corporation under this section, and none
shall be ordered by a court, if such action would be inconsistent with a
provision of the certificate of incorporation, a bylaw, a resolution of the
board of directors or of the shareholders, an agreement or other proper
corporate action, in effect at the time of the accrual of the alleged cause of
action asserted in the proceeding, which prohibits, limits or otherwise
conditions the exercise of indemnification powers by the corporation or the
rights of indemnification to which a corporate agent may be entitled.

(12) This section does not limit a corporation's power to pay or
reimburse expenses incurred by a corporate agent in connection with the
corporate agent's appearance as a witness in a proceeding at a time when the
corporate agent has not been made a party to the proceeding.

ITEM 17. UNDERTAKINGS

The undersigned registrant hereby undertakes:

(1) To file, during any period in which offers or sales are being made,
a post-effective amendment to this registration statement:

(a) To include any prospectus required by Section 10(a)(3) of
the Securities Act;

(b) To reflect in the prospectus any facts or events arising
after the effective date of the registration statement (or the most
recent post-effective amendment thereof) which, individually or in the
aggregate, represent a fundamental change in the information set forth
in the registration statement. Notwithstanding the foregoing, any
increase or decrease in volume of securities offered (if the total
dollar value of securities offered would not exceed that which was
registered) and any deviation from the low or high end of the estimated
maximum offering range may be reflected in the form of prospectus filed
with the Commission pursuant to Rule 424(b) if, in the aggregate, the
changes in volume and price represent no more than a 20% change in the
maximum aggregate offering price set forth in the Calculation of
Registration Fee table in the registration statement;

(c) To include any material information with respect to the
plan of distribution not previously disclosed in the registration
statement or any material change to such information in the
registration statement; Provided however, that paragraphs (1)(a) and
(1)(b) do not apply if the registration statement is on Form S-3, Form
S-8 or Form F-3, and the information required to be included in a
post-effective amendment by those paragraphs is contained in periodic
reports filed with or furnished to the Commission by the registrant
pursuant to Section 13 or 15(d) of the Securities Exchange Act of 1934
(the "Exchange Act") that are incorporated by reference in the
registration statement.



19


(2) For the purpose of determining any liability under the Securities
Act, each post-effective amendment that contains a form of prospectus shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.

(3) To remove from registration by means of a post-effective amendment
any of the securities being registered which remain unsold at the termination of
the offering.

(4) That, for purposes of determining any liability under the
Securities Act, each filing of the registrant's annual report pursuant to
Section 13(a) or 15(d) of the Exchange Act (and, where applicable, each filing
of an employee benefit plan's annual report pursuant to Section 15(d) of the
Exchange Act) that is incorporated by reference in the registration statement
shall be deemed to be a new registration statement relating to the securities
offered therein and the offering of such securities at that time shall be deemed
to be the initial bona fide offering thereof.

(5) That, for purposes of determining any liability under the
Securities Act, the information omitted from the form of prospectus filed as
part of this registration statement in reliance upon Rule 430A and contained in
a form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4)
or 497(h) under the Securities Act shall be deemed to be part of this
registration statement as of the time it was declared effective.

(6) Insofar as indemnification for liabilities arising under the
Securities Act may be permitted to directors, officers and controlling persons
of the registrant pursuant to provisions described in Item 15 or otherwise, the
registrant has been advised that in the opinion of the Commission such
indemnification is against public policy as expressed in the Securities Act and
is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the registrant of expenses
incurred or paid by a director, officer or controlling person of the registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act and will be governed by the final
adjudication of such issue.
