LLC, (the Holder) is entitled to subscribe for and purchase from
SuperGen, Inc, a Delaware corporation (the Company), at the Warrant
Price defined in Section 2 herein, 188,294 fully paid and non-assessable
shares of the Companys Common Stock (the Common Stock), such price and such number
of shares being subject to adjustment upon occurrence of the contingencies set
forth in this Warrant. This Warrant is issued in connection with the issuance of certain
Senior Convertible Notes by the Company pursuant to a Securities Purchase
Agreement dated June 24, 2003 between the Company and the purchaser(s) named
therein (the Purchase Agreement). Upon delivery of this Warrant (with the Notice of Exercise in the form
attached hereto as Exhibit A), together with payment of
the Warrant Price of the shares of Common Stock thereby purchased, at the
principal office of the Company or at such other office or agency as the
Company may designate by notice in writing to the holder hereof, the holder of
this Warrant shall be entitled to receive a certificate or certificates for the
shares of Common Stock so purchased. 
All shares of Common Stock which may be issued upon the exercise of this
Warrant will, upon issuance, be fully paid and non-assessable and free from all
taxes, liens and charges with respect thereto. This Warrant is
subject to the following terms and conditions: 1.             Term of Warrant. This Warrant may be
exercised in whole or in part, at any time, and from time to time, after
issuance and prior to the first to occur of the following: 
   (a)           5:00
p.m., Pacific Standard Time, June 23, 2007; or (b)           The
consummation of any transaction or series of transactions (collectively, the Transaction),
including without limitation, the sale, transfer or disposition of all or
substantially all of the Companys assets or the merger of the Company with or
into, or consolidation with, any other corporation, whereby the holders of the
Companys voting securities prior to the Transaction do not hold more than 50%
of the voting securities of the surviving entity following consummation of the
Transaction (a Change of Control). 2.             Warrant
Price.  The exercise price of this
Warrant (the Warrant Price) shall equal $6.00 per share. 3.             Adjustment
of Purchase Price and Number of Shares; Limitation on Exercise. The number and kind of
securities purchasable upon the exercise of this Warrant and the Warrant Price
shall be subject to adjustment from time to time in accordance with the
following provisions: (a)           Reclassification,
Consolidation or Merger.  In case of
any reclassification or change of outstanding securities of the class issuable
upon exercise of this Warrant (other than as a result of a subdivision or
combination), or in case of any consolidation or merger of the Company with or
into another corporation (other than a Change of Control as provided in
Section 1(b) hereof), the Company, or such successor corporation, as the
case may be, shall execute a new Warrant, providing that the holder of this
Warrant shall have the right to exercise such new Warrant and procure upon such
exercise in lieu of each share of Common Stock theretofore issuable upon
exercise of this Warrant the kind and amount of shares of stock, other
securities, money and property receivable upon such reclassification, change,
consolidation or merger by a holder of one share of Common Stock.  Such new Warrant shall provide for
adjustments which shall be as nearly equivalent as may be practicable to the
adjustments provided for in this Section 3.  The provisions of this subsection (a) shall similarly apply
to successive reclassifications, changes, consolidations and mergers. (b)           Subdivision
or Combination of Shares.  If at any
time on or after the date of this Warrant the Company shall subdivide its
outstanding shares of Common Stock into a greater number of shares, or shall
pay a dividend with respect to its outstanding shares of Common Stock in shares
of Common Stock, the Warrant Price in effect immediately prior to such
subdivision shall be proportionately reduced and the number of shares
receivable upon exercise of the Warrant shall be proportionately increased;
and, conversely, if at any time on or after the date of this Warrant the
outstanding number of shares of Common Stock shall be combined into a smaller
number of shares, the Warrant Price in effect immediately prior to such
combination shall be proportionately increased and the number of shares
receivable upon exercise of the Warrant shall be proportionately decreased. (c)           Adjustment
of Number of Shares.  Upon each
adjustment in the Warrant Price, the number of Shares of Common Stock
purchasable hereunder shall be adjusted, to the nearest whole share, to the
product obtained by multiplying the number of Shares purchasable immediately
prior to such adjustment in the Warrant Price by a fraction, the numerator of
which  2 
   shall be
the Warrant Price immediately prior to such adjustment and the denominator of
which shall be the Warrant Price immediately thereafter. 4.             Notices. (a)           Upon
any adjustment of the Warrant Price and increase or decrease in the number of
shares of Common Stock purchasable upon the exercise of this Warrant, then, and
in each such case, the Company, within thirty (30) days thereafter, shall give
written notice thereof to the registered Holder of this Warrant (the Notice).  The Notice shall be mailed to the address of
such holder as shown on the books of the Company, and shall state the Warrant
Price as adjusted and the increased or decreased number of shares purchasable
upon the exercise of this Warrant, setting forth in reasonable detail the
method of calculation of each. (b)           The
Company shall send to the Holder at least twenty (20) days prior written
notice of the date when any change of control of which the Company has
knowledge shall take place. (c)           Each
such written notice shall be given by first class mail, postage prepaid,
addressed to the Holder at the address as shown on the books of the Company for
the Holder. 5.             Investment
Letter.  Upon exercise or conversion
of this Warrant in accordance with the provisions hereof, if the Common Stock
issuable upon exercise of this Warrant is not registered as contemplated by
Section 6 below, the Holder shall either (i) execute and deliver to the Company
an investment letter in the form attached to the Notice of Exercise on Exhibit
A, or (ii) deliver to the Company an opinion of counsel for the Holder
reasonably satisfactory to the Company, stating that such exercise or
conversion is exempt from the registration and prospectus delivery requirements
of the Securities Act of 1933, as amended (the Securities Act). 6.             Registration
Rights.  The Company shall include
the shares of Common Stock issued or issuable upon the exercise of this Warrant
in the S-3 Registration Statement that the Company shall file pursuant to that
certain Registration Rights Agreement dated June 24, 2003. 7.             Restrictions
on Transfer.  Certificates
representing any of the Common Stock acquired pursuant to the provisions of
this Warrant shall have endorsed thereon legends substantially in the following
form, as appropriate. Unless such shares of Common Stock are registered under the Securities
Act and qualified (if necessary) under applicable state securities laws: (a)           THE SHARES REPRESENTED BY THIS
CERTIFICATE HAVE BEEN ACQUIRED FOR INVESTMENT AND HAVE NOT BEEN REGISTERED

SHARES MAY NOT BE SOLD OR TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION
UNLESS THE COMPANY RECEIVES AN OPINION OF COUNSEL REASONABLY ACCEPTABLE TO IT
STATING THAT SUCH SALE OR TRANSFER IS EXEMPT FROM THE REGISTRATION AND
PROSPECTUS DELIVERY REQUIREMENTS OF SAID ACT.  3 
   (b)           Any
legend required to be placed thereon by any applicable state securities laws. 8.             Compliance
with Act.  The Holder, by acceptance
hereof, agrees that this Warrant and the Common Stock to be issued upon the
exercise or conversion hereof are being acquired solely for its own account and
not as a nominee for any other party and not with a view toward the resale or
distribution thereof and that it will not offer, sell or otherwise dispose of
this War­rant or any of the Common Stock to be issued upon the exercise or
conversion hereof except in accordance herewith and under circumstances which
will not result in a violation of the Securi­ties Act or of applicable state
securities laws. 9.             Miscellaneous. (a)           The
terms of this Warrant shall be binding upon and shall inure to the benefit of
any successors or assigns of the Company and of the holder or holders hereof
and of the Common Stock issued or issuable upon the exercise hereof. (b)           No
holder of this Warrant, as such, shall be entitled to vote or receive dividends
or be deemed to be a stockholder of the Company for any purpose, nor shall
anything contained in this Warrant be construed to confer upon the holder of
this Warrant, as such, any rights of a stockholder of the Company or any right
to vote, give or withhold consent to any corporate action, receive notice of
meetings, receive dividends or subscription rights, or otherwise. (c)           Receipt
of this Warrant by the holder hereof shall constitute acceptance of and
agreement to the foregoing terms and conditions. (d)           The
Company will not, by amendment of its Restated Certificate of Incorporation or
through any other means, avoid or seek to avoid the observance or performance
of any of the terms of this Warrant, but will at all times in good faith assist
in the carrying out of all such terms and in the taking of all such action as
may be necessary or appropriate in order to protect the rights of the holder of
this Warrant against impairment. (e)           Upon
receipt of evidence reasonably satisfactory to the Company of the loss, theft,
destruction or mutilation of this Warrant and, in the case of any such loss,
theft or distribution, upon delivery of an indemnity agreement reasonably
satisfactory in form and amount to the Company or, in the case of any such
mutilation, upon surrender and cancellation of such Warrant, the Company at its
expense will execute and deliver, in lieu thereof, a new Warrant of like date
and tenor. (f)            This
Warrant shall be nontransferable, other than pursuant to (i) a transfer not
involving a change in beneficial ownership, (ii) a distribution without
consideration of the Warrant by the Holder to any of its partners, or retired
partners, or to the estate of any of its partners or retired partners, or if
the Holder is a limited liability company, to any of its members, former
members, or to the estate of any of its members or former members, (iii) any
transfer by any Holder to (A) any individual or entity controlled by,
controlling, or under common control with, such Holder or (B) any individual or
entity with respect to which such Holder (or any  4 
   person
controlled by, controlling, or under common control with, such Holder) has the
power to direct investment decisions, and (iv) a transfer exempt from
registration under the Securities Act, upon the Companys receipt of an opinion
of counsel (which may be counsel for the Company) satisfactory to the Company
stating that such transfer is exempt from the registration and prospectus
delivery requirements of the federal securities laws. (g)           This
Warrant or any provision of this Warrant may be amended, waived, discharged or
terminated by a statement in writing signed by the Company and the Holder, and
in the event of any permitted transfer(s) of this Warrant, by the Company and

  , In connection with the
purchase of the above-listed Securities, I, the Purchaser, represent to the
Company the following: (a)           I am an accredited
investor within the meaning of Rule 501 under the Securities Act of 1933,
as amended (the Securities Act) and have such knowledge and experience in
financial and business matters that I am capable of evaluating the merits and
risks of the purchase of the Securities. (b)           I am aware of the
Companys business affairs and financial condition, and have acquired
sufficient information about the Company to reach an informed and knowledgeable
decision to acquire the Securities.  In
making my decision to acquire the Securities, I am not relying on representations
of any officer, director, stockholder or agent of the Company.  I am purchasing these Securities for my own
account for investment purposes only and not with a view to, or for the resale
in connection with, any distribution thereof for purposes of the Securities
Act. (c)           I understand that
the Securities have not been registered under the Securities Act in reliance
upon a specific exemption therefrom, and that reliance by the Company on such
an exemption is predicated in part on the representations set forth in this
letter. (d)           I further understand
that the Securities must be held indefinitely unless subse­quently registered
under the Securities Act or unless an exemption from registration is otherwise
available.  In addition, I understand
that the certificate evidencing the Securities will be imprinted with a legend
which prohibits the transfer of the Securities unless they are registered or
such registration is not required in the opinion of counsel for the Purchaser
satisfactory to the Company or unless the Company receives a no-action letter
from the Securities and Exchange Commission. (e)           I am familiar with
the provisions of Rule 144, promulgated under the Securities Act, which,
in substance, permits limited public resale of restricted securities
acquired, directly or indirectly, from the issuer thereof (or from an affiliate
of such issuer), in a non-public offering subject to the satisfaction of
certain conditions, including, among other things:  (1) the resale  
   occurring not less than one year after the later of
the date the securities were sold by the Company or the date they were sold by
an affiliate of the Company, within the meaning of Rule 144; and, in the
case of an affiliate, or of a non-affiliate who has held the securities less
than two years, (2) the availability of certain public information about
the Company, (3) the sale being made through a broker in an unsolicited
brokers transaction or in transactions directly with a market maker (as said
term is defined under the Securities Exchange Act of 1934), and (4) the amount
of securities being sold during any three month period not exceeding the
specified limitations stated therein, if applicable. (f)            I further
understand that at the time I wish to sell the Securities there may be no
public market upon which to make such a sale, and that, even if such a public
market exists, the Company may not be satisfying the current public information
requirements of Rule 144, and that, in such event, I would be precluded
from selling the Securities under Rule 144 even if the one-year minimum
holding period had been satisfied. (g)           I further understand
that in the event all of the applicable requirements of Rule 144 are not
satisfied, registration under the Securities Act, compliance with
Regulation A, or some other registration exemption will be required; and
that, notwithstanding the fact that Rule 144 is not exclusive, the Staff
of the SEC has expressed its opinion that persons proposing to sell private
placement securities other than in a registered offering and otherwise than
pursuant to Rule 144 will have a substantial burden of proof in
establishing that an exemption from regis­tration is available for such offers
or sales, and that such persons and their respective brokers who participate in
such transactions do so at their own risk.  Signature
