                                   ALTEON INC.

                          Common Stock Purchase Warrant

                             (Void after five years)

Alteon Inc., a Delaware corporation (the "Company"), for value received, hereby
certifies that Rodman & Renshaw, Inc., or its registered assigns (the
"Registered Holder"), is entitled, subject to the terms and conditions set forth
below, to purchase from the Company, at any time or from time to time commencing
six months after the date of issuance and on or before 5:00 p.m. (Eastern time)
on January 13, 2010, 312,381 shares of Common Stock, of the Company, at a
purchase price of $1.37 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) 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 the Registered Holder or by the 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, of the Purchase Price payable in
respect of the number of Warrant Shares purchased upon such exercise.

      (b) The Registered Holder may, at its option, elect to pay some or all of
the Purchase Price payable upon an exercise of this Warrant by canceling all or
a portion of this Warrant. If the Registered Holder wishes to exercise this
Warrant by this method,

                                       1
<PAGE>

the number of Warrant Shares purchaseable (which shall in no event exceed the
total number of Warrant Shares purchasable under this Warrant as set forth
above), subject to adjustment under Section 2 of this Warrant) shall be
determined as follows:

            X=Y[(A-B)/A]; where

X= the number of Warrant Shares to be issued to the Holder.

Y= the number of Warrant Shares with respect to which this Warrant is being
exercised.

A= the Fair Market Value of one share of Common Stock.

B= the Purchase Price of one share of Common Stock.

      The Fair Market Value per share of Common Stock shall be determined as
follows:

            (i) If the Common Stock is listed on a national securities exchange,
      the Nasdaq National Market or another nationally recognized trading system
      (including, without limitation, the OTC Bulletin Board or any successor
      and, if the average daily trading volume for the preceding 10 days has
      been at least 100,000 shares, the Pink Sheets) as of the Exercise Date,
      the Fair Market Value per share of Common Stock shall be deemed to be the
      average of the high and low reported sale prices per share of Common Stock
      thereon on the three trading days immediately preceding the Exercise Date
      (provided that if no such price is reported on such day, the Fair Market
      Value per share of Common Stock shall be determined pursuant to clause
      (ii)).

            (ii) If the Common Stock is not listed on a national securities
      exchange, the Nasdaq National Market or another nationally recognized
      trading system as of the Exercise Date, the Fair Market Value per share of
      Common Stock shall be deemed to be the amount most recently determined by
      the Board of Directors to represent the fair market value per share of the
      Common Stock (including without limitation a determination for purposes of
      granting Common Stock options or issuing Common Stock under an employee
      benefit plan of the Company); and, upon request of the Registered Holder,
      the Board of Directors (or a representative thereof) shall promptly notify
      the Registered Holder of the Fair Market Value per share of Common Stock.
      Notwithstanding the foregoing, if the Board of Directors has not made such
      a determination within the three-month period prior to the Exercise Date,
      then (A) the Board of Directors shall make a determination of the Fair
      Market Value per share of the Common Stock within 15 days of a request by
      the Registered Holder that it do so, and (B) the exercise of this Warrant
      pursuant to this subsection 1(b) shall be delayed until such determination
      is made.

                                       2
<PAGE>

            (c) 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 1(a) above accompanied by payment in full of the Purchase Price
      (the "Exercise Date"). 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(d) below shall be deemed to have
      become the holder or holders of record of the Warrant Shares represented
      by such certificates.

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

                  (i) a certificate or certificates for the number of full
            Warrant Shares to which the Registered Holder shall be entitled upon
            such exercise plus, in lieu of any fractional share to which the
            Registered Holder would otherwise be entitled, cash in an amount
            determined pursuant to Section 3 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 remaining
            Warrant Shares.

2.  ADJUSTMENTS.

      (a) Adjustment for Stock Splits and Combinations. If the Company shall at
any time or from time to time after the date on which this Warrant was first
issued (the "Original Issue Date") effect a subdivision of the outstanding
Common Stock, the Purchase Price then in effect immediately before that
subdivision shall be proportionately decreased. If the Company shall at any time
or from time to time after the Original Issue Date combine the outstanding
shares of Common Stock, the Purchase Price then in effect immediately before the
combination shall be proportionately increased. Any adjustment under this
paragraph shall become effective at the close of business on the date the
subdivision or combination becomes effective.

      (b) Adjustment for Certain Dividends and Distributions. In the event the
Company at any time, or from time to time after the Original Issue Date shall
make or issue, or fix a record date for the determination of holders of Common
Stock entitled to receive, a dividend or other distribution payable in
additional shares of Common Stock, then and in each such event the Purchase
Price then in effect immediately before such event shall be decreased as of the
time of such issuance or, in the event such a record date shall have been fixed,
as of the close of business on such record date, by multiplying the Purchase
Price then in effect by a fraction:

                                       3
<PAGE>

      (1)   the numerator of which shall be the total number of shares of Common
      Stock issued and outstanding immediately prior to the time of such
      issuance or the close of business on such record date, and

      (2)   the denominator of which shall be the total number of shares of
      Common Stock issued and outstanding immediately prior to the time of such
      issuance or the close of business on such record date plus the number of
      shares of Common Stock issuable in payment of such dividend or
      distribution;

provided, however, if such record date shall have been fixed and such dividend
is not fully paid or if such distribution is not fully made on the date fixed
therefor, the Purchase Price shall be recomputed accordingly as of the close of
business on such record date and thereafter the Purchase Price shall be adjusted
pursuant to this paragraph as of the time of actual payment of such dividends or
distributions.

      (c) Adjustment in Number of Warrant Shares. When any adjustment is
required to be made in the Purchase Price pursuant to subsections 2(a) or 2(b),
the number of Warrant Shares purchasable upon the exercise of this Warrant shall
be changed to the number determined by dividing (i) an amount equal to the
number of shares issuable upon the exercise of this Warrant immediately prior to
such adjustment, multiplied by the Purchase Price in effect immediately prior to
such adjustment, by (ii) the Purchase Price in effect immediately after such
adjustment.

      (d) Adjustments for Other Dividends and Distributions. In the event the
Company at any time or from time to time after the Original Issue Date shall
make or issue, or fix a record date for the determination of holders of Common
Stock entitled to receive, a dividend or other distribution payable in
securities of the Company (other than shares of Common Stock) or in cash or
other property (other than cash out of earnings or earned surplus, determined in
accordance with generally accepted accounting principles), then and in each such
event provision shall be made so that the Registered Holder shall receive upon
exercise hereof, in addition to the number of shares of Common Stock issuable
hereunder, the kind and amount of securities of the Company and/or cash and
other property which the Registered Holder would have been entitled to receive
had this Warrant been exercised into Common Stock on the date of such event and
had the Registered Holder thereafter, during the period from the date of such
event to and including the Exercise Date, retained any such securities
receivable, giving application to all adjustments called for during such period
under this Section 2 with respect to the rights of the Registered Holder.

      (e) Adjustment for Mergers or Reorganizations, etc. If there shall occur
any reorganization, recapitalization, consolidation or merger involving the
Company in which the Common Stock is converted into or exchanged for securities,
cash or other property (other than a transaction covered by subsections 2(a),
2(b) or 2(d)), then, following any such reorganization, recapitalization,
consolidation or merger, the Registered Holder shall receive upon exercise
hereof the kind and amount of securities, cash or other property which the
Registered Holder would have been entitled to receive if,

                                       4
<PAGE>

immediately prior to such reorganization, recapitalization, consolidation or
merger, the Registered Holder had held the number of shares of Common Stock
subject to this Warrant. Notwithstanding the foregoing sentence, in the event
the value of the stock, securities or other assets or property (determined in
good faith by the Board of Directors of the Company) issuable or payable with
respect to one share of the Common Stock in connection with such reorganization,
recapitalization, consolidation or merger is in excess of the Purchase Price in
effect at the time of such reorganization, recapitalization, consolidation or
merger and securities received in such reorganization, recapitalization,
consolidation or merger, if any, are publicly traded, then this Warrant shall
expire unless exercised prior to such reorganization, recapitalization,
consolidation or merger. In any such case, appropriate adjustment (as determined
in good faith by the Board of Directors of the Company) shall be made in the
application of the provisions set forth herein with respect to the rights and
interests thereafter of the Registered Holder, to the end that the provisions
set forth in this Section 2 (including provisions with respect to changes in and
other adjustments of the Purchase Price) shall thereafter be applicable, as
nearly as reasonably may be, in relation to any securities, cash or other
property thereafter deliverable upon the exercise of this Warrant.

      (e) Certificate as to Adjustments. Upon the occurrence of each adjustment
or readjustment of the Purchase Price pursuant to this Section 2, the Company at
its expense shall promptly compute such adjustment or readjustment in accordance
with the terms hereof and furnish to the Registered Holder a certificate setting
forth such adjustment or readjustment (including the kind and amount of
securities, cash or other property for which this Warrant shall be exercisable
and the Purchase Price) and showing in detail the facts upon which such
adjustment or readjustment is based. The Company shall, upon the written request
at any time of the Registered Holder, furnish or cause to be furnished to the
Registered Holder a certificate setting forth (i) the Purchase Price then in
effect and (ii) the number of shares of Common Stock and the amount, if any, of
other securities, cash or property which then would be received upon the
exercise of this Warrant.

3. FRACTIONAL SHARES. The Company shall not be required upon the exercise of
this Warrant to issue any fractional shares, but shall make an adjustment
therefor in cash on the basis of the Fair Market Value per share of Common
Stock, as determined pursuant to subsection 1(b) above.

4. REQUIREMENTS FOR TRANSFER. (a) For a period of six months after the issuance
date of this Warrant (which shall not be earlier than the closing date of the
offering pursuant to which this Warrant is being issued), no sale, transfer
assignment or hypothecation of this Warrant may be made to any person except an
officer or employee (but not a director) of Rodman & Renshaw, Inc. or of another
NASD member firm which is part of the selling group in the aforesaid offering.

      (b) Subject to the foregoing restrictions, the Company agrees that, at any
time or times hereafter, as and when it intends to register any of its
securities under the Securities Act of 1933, as amended (the "Securities Act")
(except in connection with an

                                       5
<PAGE>

offering on Form S-8 or an offering solely related to an acquisition or exchange
on a Form S-4 or any subsequent similar form) the Company will notify the Holder
of such intention and, upon request from the Holder, will use its reasonable
best efforts to cause the Warrant Shares designated by the Holder to be
registered for resale under the Securities Act. The number of Warrant Shares to
be included in such offering may be reduced if and to the extent that the
underwriter of securities included in the registration statement and offered by
the Company shall be of the opinion that such inclusion would adversely affect
the marketing of the securities to be sold by the Company therein; provided,
however, that the percentage of the reduction of such Warrant Shares shall be no
greater than the percentage reduction of securities of other selling
stockholders, as such percentage reductions are determined in the good faith
judgment of the Company. The Company will use its reasonable best efforts to
keep such registration statement (or another registration statement for such
purpose) in effect until at least the second anniversary of the Original Issue
Date.

5. NO IMPAIRMENT. The Company will not, by amendment of its charter or through
any reorganization, transfer of assets, consolidation, merger, dissolution,
issue or sale of securities or any other voluntary action, 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.

6. NOTICES OF RECORD DATE, ETC. In the event:

      (a) the Company shall take a record of the holders of its Common Stock (or
other stock or securities at the time deliverable upon the exercise of this
Warrant) for the purpose of entitling or enabling them to receive any dividend
or other distribution, or to receive any right to subscribe for or purchase any
shares of stock of any class or any other securities, or to receive any other
right;

      (b) of any capital reorganization of the Company, any reclassification of
the Common Stock of the Company, any consolidation or merger of the Company with
or into another corporation (other than a consolidation or merger in which the
Company is the surviving entity and its Common Stock is not converted into or
exchanged for any other securities or property), or any transfer of all or
substantially all of the assets of the Company; or

      (c) of the voluntary or involuntary dissolution, liquidation or winding-up
of the Company,

then, and in each such case, the Company will mail or cause to be mailed to the
Registered Holder a notice specifying, as the case may be, (i) the record date
for such dividend, distribution or right, and the amount and character of such
dividend, distribution or right, or (ii) the effective date on which such
reorganization,

                                       6
<PAGE>

reclassification, consolidation, merger, transfer, dissolution, liquidation or
winding-up is to take place, and the time, if any is to be fixed, as of which
the holders of record of Common Stock (or such other stock or securities at the
time deliverable upon the exercise of this Warrant) shall be entitled to
exchange their shares of Common Stock (or such other stock or securities) for
securities or other property deliverable upon such reorganization,
reclassification, consolidation, merger, transfer, dissolution, liquidation or
winding-up. Such notice shall be mailed at least ten days prior to the record
date or effective date for the event specified in such notice.

7. RESERVATION OF STOCK. The Company will at all times reserve and keep
available, solely for issuance and delivery upon the exercise of this Warrant,
such number of Warrant Shares and other securities, cash and/or property, as
from time to time shall be issuable upon the exercise of this Warrant.

8. EXCHANGE OF WARRANTS. Upon the surrender by the Registered Holder, properly
endorsed, to the Company at the principal office of the Company, the Company
will, subject to the provisions of Section 4 hereof, issue and deliver to or
upon the order of such Holder, at the Company's expense, a new Warrant or
Warrants of like tenor, in the name of the Registered Holder or as the
Registered Holder (upon payment by the Registered Holder of any applicable
transfer taxes) may direct, calling in the aggregate on the face or faces
thereof for the number of shares of Common Stock (or other securities, cash
and/or property) then issuable upon exercise of this Warrant.

9. REPLACEMENT OF WARRANTS. Upon receipt of evidence reasonably satisfactory to
the Company of the loss, theft, destruction or mutilation of this Warrant and
(in the case of loss, theft or destruction) upon delivery of an indemnity
agreement (with surety if reasonably required) in an amount reasonably
satisfactory to the Company, or (in the case of mutilation) upon surrender and
cancellation of this Warrant, the Company will issue, in lieu thereof, a new
Warrant of like tenor.

10. TRANSFERS, ETC.

      (a) The Company will maintain a register containing the name and address
of the Registered Holder of this Warrant. The Registered Holder may change its
or his address as shown on the warrant register by written notice to the Company
requesting such change.

      (b) Subject to compliance with applicable securities laws, the legend set
forth at the top of this Warrant and the provisions of Section 4 hereof, this
Warrant and all rights hereunder are transferable, in whole or in part, upon
surrender of this Warrant with a properly executed assignment (in the form of
Exhibit II hereto) at the principal office of the Company.

      (c) Until any transfer of this Warrant is made in the warrant register,
the Company may treat the Registered Holder as the absolute owner hereof for all
purposes; provided, however, that if and when this Warrant is properly assigned
in

                                       7
<PAGE>

blank, the Company may (but shall not be obligated to) treat the bearer hereof
as the absolute owner hereof for all purposes, notwithstanding any notice to the
contrary.

11. REPRESENTATIONS OF THE REGISTERED HOLDER. The Registered Holder of this
Warrant represents and warrants to the Company as follows:

      (a) Investment. The Registered Holder is acquiring this Warrant and the
Warrant Shares issuable upon the exercise of this Warrant, for its own account
for investment and not with a view to, or for sale in connection with, any
distribution thereof, nor with any present intention of distributing or selling
the same, except as otherwise may be permitted under applicable securities laws.

      (b) Authority. The Registered Holder has full power and authority to enter
into and to perform this Warrant in accordance with its terms. The Registered
Holder has not been organized specifically for the purpose of investing in the
Company.

      (c) Accredited Investor. The Registered Holder is an Accredited Investor
within the definition set forth in Rule 501(a) promulgated under the Securities
Act.

12. MAILING OF NOTICES, ETC. All notices and other communications from the
Company to the Registered Holder shall be mailed by first-class certified or
registered mail, postage prepaid, to the address last furnished to the Company
in writing by the Registered Holder. All notices and other communications from
the Registered Holder or in connection herewith to the Company shall be mailed
by first-class certified or registered mail, postage prepaid, to the Company at
its principal office set forth below. If the Company should at any time change
the location of its principal office to a place other than as set forth below,
it shall give prompt written notice to the Registered Holder and thereafter all
references in this Warrant to the location of its principal office at the
particular time shall be as so specified in such notice.

13. NO RIGHTS AS STOCKHOLDER. Until the exercise of this Warrant, the Registered
Holder shall not have or exercise any rights by virtue hereof as a stockholder
of the Company. Notwithstanding the foregoing, in the event (i) the Company
effects a split of the Common Stock by means of a stock dividend and the
Purchase Price of and the number of Warrant Shares are adjusted as of the date
of the distribution of the dividend (rather than as of the record date for such
dividend), and (ii) the Registered Holder exercises this Warrant between the
record date and the distribution date for such stock dividend, the Registered
Holder shall be entitled to receive, on the distribution date, the stock
dividend with respect to the shares of Common Stock acquired upon such exercise,
notwithstanding the fact that such shares were not outstanding as of the close
of business on the record date for such stock dividend.

14. CHANGE OR WAIVER. Any term of this Warrant may be changed or waived only by
an instrument in writing signed by the party against which enforcement of the
change or waiver is sought.

                                       8

15. SECTION HEADINGS. The section headings in this Warrant are for the
convenience of the parties and in no way alter, modify, amend, limit or restrict
the contractual obligations of the parties.

16. GOVERNING LAW. This Warrant will be governed by and construed in accordance
with the internal laws of the State of New York (without reference to the
conflicts of law provisions thereof).

      EXECUTED as of the Date of Issuance indicated above.

Exhibit III

INVESTMENT REPRESENTATION


THIS AGREEMENT MUST BE COMPLETED, SIGNED AND RETURNED TO ALTEON INC. ALONG WITH
THE PURCHASE FORM BEFORE THE COMMON STOCK ISSUABLE UPON EXERCISE OF THIS WARRANT
WILL BE ISSUED.

      The undersigned, __________________________ ("Purchaser"), intends to
acquire _____________ shares of the Common Stock (the "Common Stock") of Alteon
Inc. (the "Company") from the Company pursuant to the exercise or conversion of
a certain Warrant to purchase Common Stock held by Purchaser. The Common Stock
will be issued to Purchaser in a transaction not involving a public offering and
pursuant to an exemption from registration under the Securities Act of 1933, as
amended (the "Securities Act") and applicable state securities laws. In
connection with such purchase and in order to comply with the exemptions from
registration relied upon by the Company, Purchaser represents, warrants and
agrees as follows:

      Purchaser is acquiring the Common Stock for its own account for investment
and not with a view to, or for sale in connection with, any distribution
thereof, nor with any present intention of distributing or selling the same,
except as otherwise may be permitted under applicable securities laws.

      Purchaser has full power and authority to enter into and to perform the
Purchase Form to which this letter is attached. Purchaser has not been organized
specifically for the purpose of investing in the Company.

      Purchaser is an Accredited Investor within the definition set forth in
Rule 501(a) promulgated under the Securities Act.

      Purchaser has been advised that the Common Stock has not been registered
under the Securities Act or state securities laws on the ground that this
transaction is exempt from registration, and that reliance by the Company on
such exemptions is predicated in part on Purchaser's representations set forth
in this letter.

      Purchaser has been informed that under the Securities Act, the Common
Stock must be held indefinitely unless it is subsequently registered under the
Securities Act or unless an exemption from such registration (such as Rule 144)
is available with respect to any proposed transfer or disposition by Purchaser
of the Common Stock. Purchaser further agrees that the Company may refuse to
permit Purchaser to sell, transfer or dispose of the Common Stock (except as
permitted under Rule 144) unless there is in effect a registration statement
under the Securities Act and any applicable state securities laws covering such
transfer, or unless Purchaser furnishes an opinion of

                                       12

counsel reasonably satisfactory to counsel for the Company, to the effect that
such registration is not required.

      Purchaser also understands and agrees that there will be placed on the
certificate(s) for the Common Stock, or any substitutions therefor, a legend
stating in substance:

      "The shares represented by this certificate have not been registered under
      the Securities Act of 1933, as amended (the "Securities Act"), or any
      state securities laws. These shares have been acquired for investment and
      may not be sold or otherwise transferred in the absence of an effective
      registration statement for these shares under the Securities Act and
      applicable state securities laws, or an opinion of counsel satisfactory to
      the Company that registration is not required and that an applicable
      exemption is available."

                                       13

      Purchaser has carefully read this letter and has discussed its
requirements and other applicable limitations upon Purchaser's resale of the
Common Stock with Purchaser's counsel.

                                        Very truly yours,

                                        By: __________________________
