EMCORE CORPORATION
SOMERSET, NEW JERSEY
ISSUE DATE: SEPTEMBER 1, 1996
WARRANT

EMCORE CORPORATION, a New Jersey corporation (the "Company"), for value
received, hereby certifies that Jesup & Lamont Merchant Partners, L.L.C., or
its registered assigns (the "Registered Holder"), is entitled, subject to the
terms set forth below, to purchase from the Company, at any time or from time
to time on or after March 1, 199_, and on or before September 1, 2001, at no
later than 5:00 p.m. (New York City time), up to 833,333 shares of the common
stock of the Company ("Common Stock"), at a purchase price of $3.00 per share.
The shares purchasable upon exercise of this Warrant, and the purchase price
per share, each as adjusted from time to time pursuant to the provisions of
this Warrant, are hereinafter referred to as the "Warrant Shares" and the
"Purchase Price," respectively.

1. Exercise.

(a) Subject to the requirements of Section 4, this Warrant may be
exercised by the Registered Holder, in whole or in part, by surrendering this
Warrant, with the purchase form appended hereto as Exhibit I duly executed by
such Registered Holder or by such Registered Holder's duly authorized
attorney, at the principal office of the Company, or at such other office or
agency as the Company may designate, accompanied by payment in full, in lawful
money of the United States, or with an equal principal amount the Company's 6%
Subordinated Notes due September 1, 2001, of the Purchase Price payable in
respect of the number of shares of Warrant Shares purchased upon such
exercise.

(b) Each exercise of this Warrant shall be deemed to have been
effected immediately prior to the close of business on the day on which this
Warrant shall have been surrendered to the Company as provided in subsection
l(a) above. At such time, the person or persons in whose name or names any
certificates for warrant shares shall be issuable upon such exercise as
provided in subsection 1(c) below shall be deemed to have become the holder or
holders of record of the Warrant Shares represented by such certificates.

(c) As soon as practicable after the exercise of this Warrant in
full or in part, and in any event within 10 days thereafter, the Company, at
its expense, will cause to be issued in the name of, and delivered to, the
Registered Holder, or such Holder (upon payment by such Holder of any
applicable transfer taxes) as the Holder may direct:

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

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



2. Call provision.

This Warrant may be called in whole or in part by the Board of Directors of
the Company upon 30 days written notice to the holder at any time after
September 1, 1997. No call of this warrant shall be made unless the call is
made pro-rata as to principal amount with respect to all then outstanding
warrants of this class.

3. Adjustments.

(a) Effect of stock changes. If, at any time or from time to time
the Company, by stock dividend, stock split, subdivision, reverse split,
consolidation, reclassification of shares, or other similar structural change,
changes as a whole its outstanding Common Stock into a different number or
class of shares, then, immediately upon the occurrence of the change:

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

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

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

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

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



Warrant, may be exercised.


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

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

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

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

(iii) a brief description of the transaction;

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

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

On the date of the transaction, if it actually occurs, this Warrant and all
rights existing under this Warrant shall terminate.
4. Fractional Shares. The Company shall not be required upon the
exercise of this Warrant to issue any fractional shares, but shall pay in cash



an amount determined by multiplying the fraction to which the Holder is
entitled by the fair market value of the Common Stock on the date of exercise.
Should the Common Stock then be traded on an Exchange or quoted on a quotation
system for which a last sale reporting system is in effect, the reported last
sale on the exercise date shall be deemed to be such fair market value. If the
Common Stock is quoted on a quotation system without last sale reporting, the
fair market value shall be deemed to be the highest bid price of any
broker/dealer regularly making a market in the Common Stock on the exercise
date. In all other cases fair market value shall be as determined in good
faith by the Company.

5. Certain Requirements for Transfer and Exercise.

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

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

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

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

MEANING OF REGULATION S UNDER THE SECURITIES ACT, AS THE SAME MAY BE

satisfactory to the Company of the loss, theft, destruction or mutilation of

obligated to) treat the bearer hereof as the absolute owner hereof for all
purposes, notwithstanding any notice to the contrary.

10. Required Notices. The Company shall give the Registered Holder such
notices as it may, from time to time, be required to give the holders of the

Registered Holder written notice of: (i) each adjustment of the Purchase Price
