        THE COMPANY'S 1997 ANNUAL REPORT ACCOMPANIES THE PROXY STATEMENT.

                                   ALTEON INC.
                               170 WILLIAMS DRIVE
                            RAMSEY, NEW JERSEY 07446

                                 PROXY STATEMENT

      This Proxy Statement is furnished in connection with the solicitation by
the Board of Directors of Alteon Inc. (the "Company") of proxies to be voted at
the Annual Meeting of Stockholders of the Company to be held on July 22, 1998,
(the "Meeting") at the Sheraton Crossroad Hotel, One International Boulevard,
Mahwah, New Jersey, at 9:00 AM, local time, and at any adjournment or
adjournments thereof. Holders of record of Common Stock, $.01 par value ("Common
Stock"), as of the close of business on May 28, 1998, will be entitled to notice
of and to vote at the Meeting and any adjournment or adjournments thereof. As of
that date, there were 17,974,125 shares of Common Stock issued and outstanding
and entitled to vote. Each share of Common Stock is entitled to one vote on any
matter presented at the Meeting.

      If proxies in the accompanying form are properly executed and returned,
the Common Stock represented thereby will be voted in the manner specified
therein. If not otherwise specified, the Common Stock represented by the proxies
will be voted (i) FOR the election of the nominees below as directors, (ii) FOR
the proposal to amend the Restated Certificate of Incorporation of Alteon Inc.
to increase the authorized number of shares of Common Stock from 30,000,000
shares to 40,000,000 shares, (iii) FOR the proposal to approve the removal of
certain limitations regarding the Company's Series G Preferred Stock and Series
H Preferred Stock, (iv) FOR the ratification of the appointment of Arthur
Andersen LLP as independent public accountants for the year ending December 31,
1998, and (v) in the discretion of the persons named in the enclosed form of
proxy, on any other proposals which may properly come before the Meeting or any
adjournment or adjournments thereof. Any stockholder who has submitted a proxy
may revoke it any time before it is voted by written notice addressed to and
received by the Secretary of the Company, by submitting a duly executed proxy
bearing a later date or by electing to vote in person at the Meeting. The mere
presence at the Meeting of the person appointing a proxy does not, however,
revoke the appointment.

      The presence, in person or by proxy, of holders of Common Stock having a
majority of the votes entitled to be cast at the Meeting shall constitute a
quorum. Votes withheld, abstentions and broker non-votes will be counted for
purposes of determining the presence or absence of a quorum.

      Directors are elected by a plurality vote. All other actions proposed
herein may be taken upon the affirmative vote of stockholders possessing a
majority of the voting power represented at the Meeting, provided a quorum is
present in person or by proxy. Only votes cast "for" a matter will constitute
affirmative votes. Votes withheld or abstentions, because they are not cast
"for" a particular proposal, will have the same effect as negative votes or
votes cast "against" such a particular proposal. Proxies submitted by brokers
that do not indicate a vote for some of the proposals because such brokers do
not have discretionary voting authority on those proposals and have not received
instructions from their customers on those proposals (i.e., broker non-votes)
are not considered to be shares present for the purpose of calculating the vote
on such proposals and will not affect the outcome of such proposals.

      This Proxy Statement, together with the related proxy card, is being
mailed to the stockholders of the Company on or about June 8, 1998. The Annual
Report to Stockholders of the Company for the year ended December 31, 1997,
including financial statements (the "Annual Report"), is being mailed
concurrently with this Proxy Statement to all stockholders of record as of May
28, 1998. In addition, the Company has provided brokers, dealers, banks, voting
trustees and their nominees, at the Company's expense, with additional copies of
the Annual Report so that such record holders may supply such material to
beneficial owners as of May 28, 1998.

                              ELECTION OF DIRECTORS

      At the Meeting two directors are to be elected to hold office until the
Annual Meeting of Stockholders to be held in 2001 and until their successors
shall have been elected and qualified. The 


   6
nominees for election to the Board of Directors are Marilyn G. Breslow and Alan
J. Dalby.

      Pursuant to the Company's Restated Certificate of Incorporation, the Board
of Directors is divided into three classes, each of which serves a term of three
years. Class A consists of Ms. Breslow and Mr. Dalby, whose terms will expire at
the Meeting. Class B consists of Mr. Mauzey, Dr. Goyan and Dr. Cerami, whose
terms will expire at the Annual Meeting of Stockholders in 1999. Class C
consists of Dr. Butler, Mr. McCurdy, and Dr. Novitch, whose terms will expire at
the Annual Meeting of Stockholders in 2000.

      It is the intention of the persons named in the enclosed form of proxy to
vote the stock represented thereby, unless otherwise specified in the proxy, for
the election as director of each of Ms. Breslow and Mr. Dalby, whose names and
biographies appear below. There are currently eight members of the Board. All of
the persons whose names and biographies appear below are at present directors of
the Company. In the event any nominee should become unavailable or unable to
serve as a director, it is intended that votes will be cast for a substitute
nominee designated by the Board of Directors. The Board of Directors has no
reason to believe that the nominees named will be unable to serve if elected.
The nominees have consented to being named in this Proxy Statement and to serve
if elected.

      The current Board of Directors, including the nominees, is comprised of
the following persons:

implemented compensation policies, plans and programs which (1) provide a total
compensation package which is intended to be competitive within the industry so
as to enable the Company to attract and retain high-caliber executive personnel,
and (2) seek to align the financial interests of the Company's employees with
those of its stockholders by relying heavily on long-term incentive compensation
which is tied to performance.

      The primary components of executive compensation include base salary and
long-term equity incentives in the form of stock options. As the Company has not
yet generated any revenue from the sale of pharmaceutical products, the Company
relies on long-term incentive compensation (i.e., stock options) to motivate the
executive officers and other employees. This allows the Company to retain cash
for research projects. In determining the size of such stock option grants to
individual executives, the Committee considers a number of factors, including
the following: the level of an executive's job responsibilities; the executive's
past performance; the size and frequency of grants by comparable 


                                       8
   13
companies; the executive's salary level; performance of the Company as measured
by the accomplishment of key business development and clinical milestones; the
size of any prior grants; and the achievement of designated milestones by the
executive. The Committee assigns no specific weight to any of the foregoing,
other than achievement of designated milestones by the executive in cases where
the executive's employment agreement provides for a grant of a specific size
upon achievement of the milestone, when making determinations as to the size of
stock option grants.

      Executive officers are also eligible to earn an annual cash incentive
award, the amount of which is based upon (1) the position level of the executive
officer, and (2) the attainment of specific individual non-financial performance
objectives. The Committee sets the performance objectives at the beginning of
the fiscal year.

      The Chief Executive Officer and the Chief Operating Officer are
responsible for the development of the annual salary plan for executive officers
other than themselves. The plan is based on industry and peer group comparisons
and national surveys and on performance judgments as to the past and expected
future contributions of the individuals. To maintain a competitive level of
compensation, the Company targets base salary at the mid to upper percentiles of
a comparative group composed of other biotechnology companies. Base salary may
exceed this level as a result of individual performance. The Committee reviews
the annual plan and makes recommendations to the Board of Directors, with any
modifications it deems appropriate. The Committee believes it has established
executive compensation levels which are competitive with companies in the
industry taking into account individual experience, performance of both the
Company and the individual, company size, location and stage of development.

Compensation of the Chief Executive Officer

      Mr. Mauzey's compensation was determined on the basis of his expertise and
experience which include approximately 25 years of experience in the
pharmaceutical industry. Compensation awarded to Mr. Mauzey in 1997 included
base salary, a performance bonus based on the achievement of milestones
(including, inter alia, securing a corporate partnership for pimagedine,
maintaining the Company's cash burn rate from operations at budget, filing a new
investigational drug application with the U.S. Food and Drug Administration, and
completion of a Phase II trial for pimagedine) and stock options.

      Effective January 1, 1994, the Internal Revenue Code does not permit
corporations to deduct payment of certain compensation in excess of $1,000,000
to the chief executive officer and the four other most highly-paid executive
officers. All compensation paid to the Company's executive officers for 1997
will be fully deductible and the Committee anticipates that amounts paid as cash
compensation will continue to be fully deductible because the amounts are
expected to be less than the $1,000,000 threshold. Under certain circumstances,
the executive officers may realize compensation upon the exercise of stock
options granted under the Company's stock option plans which would not be
deductible by the Company. The Company expects to take such action as is
necessary to qualify its stock option plans as "performance-based compensation,"
which is not subject to the limitation, if and when the Committee determines
that the effect of the limitation on deductibility warrants such action.

Company.

CHANGE IN CONTROL SEVERANCE BENEFITS PLAN

      In February 1996, the Company adopted the Alteon Inc. Change in Control
Severance Benefits Plan (the "Severance Plan"). The Severance Plan was adopted
to protect and retain qualified employees and to encourage their full attention,
free from distractions caused by personal uncertainties and risks in the event
of a pending or threatened change in control of the Company. The Severance Plan
provides for severance benefits to employees upon certain terminations of
employment after or in connection with a change in control of the Company as
defined in the Severance Plan. Following a qualifying termination which occurs
as a result of a change in control, officers of the Company will be entitled to
continuation of (i) their base salary for a period of twenty-four months, and
(ii) all benefit programs and plans providing for health and insurance benefits
for a period of up to eighteen months. In addition, upon a change in control of
the Company all outstanding unexercisable stock options held by employees will
become exercisable.

401(k) PLAN

      In 1990, the Company adopted a tax-qualified employee savings and
retirement plan (the "401(k) Plan") covering all of the Company's employees.
Pursuant to the 401(k) Plan, employees may elect to reduce their current
compensation by up to the statutorily prescribed annual limit ($10,000 in 1998)
and have the amount of such reduction contributed to the 401(k) Plan. The 401(k)
Plan does not require additional matching contributions to the Plan by the
Company on behalf of participants in the Plan. Contributions by employees to the
Plan and income earned on such contributions are not taxable to employees until
withdrawn from the 401(k) Plan. The Trustees under the 401(k) Plan, at the
direction of each participant, invest the assets of the 401(k) Plan in any of
eight investment options.

                 CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

Transactions With Management and Others

Consulting Agreements

      The Company has entered into consulting arrangements with key consultants
and members of its Scientific Advisory Board who advise the Company about
present and long-term scientific planning, research and development.

      The Company entered into a consulting agreement dated as of April 1, 1998
(the "Consulting Agreement") with Cerami Consulting Corporation ("Cerami
Consulting"), a corporation of which Dr. Anthony Cerami, a director of the
Company, is the President and his daughter, Dr. Carla Cerami, is the sole
shareholder. Pursuant to the Consulting Agreement, Cerami Consulting is paid a
fee of $250,000 per calendar year to provide services regarding advanced
glycosylation endproducts ("A.G.E.s") and certain glucose lowering agents.
Further, the Consulting Agreement provides that to the extent Cerami Consulting
provides material services with respect to the Company's A.G.E. breakers
program, the Company will pay Cerami Consulting a fee of $200,000 per calendar
year. Cerami Consulting was also granted options to purchase 100,000 shares of
the Common Stock of the Company at an exercise price of $5.125 per share, such
options to vest upon the accomplishment of milestones, as compensation for
certain prior services provided to the Company. The Consulting Agreement has an
initial term of three years, after which it is subject to automatic one year
extensions, unless it is terminated upon notice as set forth in the Consulting
Agreement.

      In April 1998, the Company entered into a research agreement (the
"Research Agreement") with Kenneth S. Warren Laboratories, Inc. ("Warren
Laboratories"), a non-profit corporation of which Dr. Anthony Cerami is a
director and the President, and Dr. Carla Cerami is a director and the Secretary
and Treasurer. Warren Laboratories will conduct a research program for the
Company with respect to A.G.E.s and certain glucose lowering agents, and the
Company will provide funding up to an initial maximum of $400,000 per calendar
year. The maximum funding amount will be raised to $750,000 per calendar year in
the event the Company reaches certain financial objectives. The Company has also
agreed to grant to Warren Laboratories options to purchase up to 500,000 shares
of the Common Stock of the Company at an exercise price of $8.75 per share in
partial consideration of Warren Laboratories' services, such options to be
granted upon the occurrence of specified events. The Research Agreement has an
initial term of three years, after which it is subject to automatic one year
extensions, unless it is terminated upon notice as set forth in the Research
Agreement.

Registration Rights

      In December 1990, the Company, the holders of each of the common shares
underlying certain preferred stock of the Company and certain holders of the
Common Stock, including Dr. Anthony Cerami, entered into an Amended and Restated
Registration and Right of First Offer Agreement (the "Rights Agreement")
pursuant to which the Company granted certain registration rights and rights of
first offer to certain stockholders. The Rights Agreement terminated March 1,
1997.

Indebtedness of Management

      In July 1993, the Company lent $200,000 to Jere E. Goyan at an interest
rate equal to the prime rate as published in the Wall Street Journal, adjusted
quarterly, for the purpose of purchasing a home. Dr. Goyan is the President,
Chief Operating Officer and a director of the Company. The loan is secured by a
second mortgage on the premises purchased by Dr. Goyan. In February 1998, the
terms of the loan were amended so that interest will stop accruing as of July
1999 and the principal and interest shall be paid in equal installments in July,
1999, 2000 and 2001. In the event an installment is not paid when due, interest
shall accrue at a rate of one percent per month until payment is made. The
largest aggregate amount outstanding during fiscal year 1997 was $284,925 on
December 31, 1997. A $25,000 payment was made 


                                       15

on December 31, 1997. As of April 30, 1998, $267,265, including accrued
interest, remained outstanding.

                   FROM 30,000,000 SHARES TO 40,000,000 SHARES

      The Board of Directors has adopted a resolution recommending that the
stockholders consider and adopt at the Meeting an amendment to Article FOURTH of
the Company's Restated Certificate of Incorporation. The proposed amendment
would increase the number of authorized shares of Common Stock, $.01 par value
per share, from 30,000,000 to 40,000,000 shares.

      For the reasons described below, the Board of Directors believes that the
proposed amendment is in the best interests of the Company and its stockholders.
If the amendment is approved, it will become effective upon the filing of a
Certificate of Amendment to the Restated Certificate of Incorporation with the
Secretary of State of Delaware. The text of the proposed amended Article FOURTH
is set forth below:

      "FOURTH: The total number of shares of all classes of stock which
      the Company shall have authority to issue is 44,000,000 shares. The
      Company is authorized to issue two classes of stock designated
      "Common Stock" and "Preferred Stock," respectively. The total number
      of shares of Common Stock authorized to be issued by the Company is
      40,000,000, and each such share of Common Stock shall have a par
      value of $.01 per share. The total number of shares of Preferred
      Stock authorized to be issued by the Company is 4,000,000, and each
      such share shall have a par value of $.01 per share."

      The Board of Directors believes that it is in the best interests of the
Company to increase the Company's authorized Common Stock in order to meet
possible contingencies and opportunities for which the issuance of Common Stock
may be deemed advisable. From time to time the Company has given, and in the
future is likely to give, consideration to the feasibility of obtaining funds
for appropriate corporate objectives, such as advancement of its A.G.E. breakers
program, through the public or private sale of equity securities. The ability to
issue additional shares of Common Stock in any future capital raising endeavor
or expansion transaction, without the costs and delays incident to obtaining
stockholder approval at the time of such issuance, is vital to the success of
the Company in a competitive marketplace.

      The Company has no current plans and has not entered into any arrangements
or understandings whereby it would be required to issue any of the additional
shares of Common Stock for which authority is now sought. Purposes for which the
additional shares of Common Stock could be issued include financing
transactions, the acquisition of the shares or assets of other corporations,
stock splits or dividends, dividend reinvestment programs and employee benefit
plans.

      As of April 30, 1998, there were 17,974,125 shares of Common Stock issued
and outstanding. The Company has reserved additional shares of Common Stock in
connection with the conversion of its outstanding preferred stock, the exercise
of outstanding warrants and the exercise of options granted under the Company's
Amended and Restated 1987 Stock Option Plan and Amended 1995 Stock Option Plan.
In the opinion of the Board of Directors, the remaining authorized and unissued
shares of Common Stock are insufficient to meet the capital needs of the
Company.

      The newly authorized shares of Common Stock, which will be identical to
the shares of Common Stock presently authorized, may be issued for such
consideration as shall be authorized from time to time by the Board of
Directors, subject to any required regulatory approvals, but without further
action by the stockholders unless specifically required by applicable law or
Nasdaq rules. In connection with any issuance and sale of such shares, the
number of shares to be issued and sold and the terms upon which they may be
issued and sold will necessarily be determined by conditions existing at the
time of such issuance and sale. 


                                       16
   21
Stockholders of the Company do not have the preemptive right to subscribe on a
pro-rata basis to any future issuance of shares. If the Company elects to issue
additional shares of Common Stock, stockholders would not have any preferential
right to purchase them, and their ownership would therefore be diluted.

      Although the Board is not aware of any effort by any person to acquire
control of the Company, the authorized but unissued shares could be used to make
it more difficult to effect a change in control, and thereby make it more
difficult for stockholders to obtain an acquisition premium for their shares or
remove incumbent management. Such shares could be used to create impediments for
persons seeking to gain control of the Company by means of a merger, tender
offer, proxy contest or other means. For example, substantial dilution of a
potential acquiring party could be achieved through private placement of
securities with purchasers who might cooperate with the Board of Directors in
opposing the potential acquiring party. The Amendment is not part of a plan by
the Company's Board of Directors to propose a series of new anti-takeover
measures and the Board of Directors does not presently intend to propose
additional anti-takeover measures in future proxy solicitations.

      In accordance with the Delaware Corporation Act, the proposed amendment to
the Restated Certificate of Incorporation must be approved by the affirmative
vote of the holders of at least a majority of the outstanding shares of the
Company's Common Stock.

      THE BOARD OF DIRECTORS RECOMMENDS A VOTE FOR THE PROPOSED AMENDMENT TO THE
RESTATED CERTIFICATE OF INCORPORATION TO INCREASE THE NUMBER OF AUTHORIZED
SHARES OF COMMON STOCK FROM 30,00000 TO 40,000,000 SHARES.


                   APPROVAL OF REMOVAL OF CERTAIN LIMITATIONS
                             REGARDING THE COMPANY'S
              SERIES G PREFERRED STOCK AND SERIES H PREFERRED STOCK


      This proposal seeks stockholder approval of the removal of certain
limitations on the issuance and conversion of the Company's Series G Preferred
Stock and Series H Preferred Stock as described below.

Background

      The Company entered into a Stock Purchase Agreement (the "Agreement")
dated as of December 1, 1997 with Genentech, Inc. ("Genentech") pursuant to
which Genentech agreed to purchase, and the Company agreed to sell, an aggregate
of $15,000,000 of the Company's Common Stock and Series G Preferred Stock and up
to $48,000,000 of the Company's Series H Preferred Stock. (The Series G
Preferred Stock and the Series H Preferred Stock are referred to in this Proxy
Statement as the "Preferred Stock"). At the same time, the Company and Genentech
entered into a Development Collaboration and License Agreement pursuant to which
Genentech received an exclusive license to use and sell certain of the Company's
products in certain areas of the world and the Company and Genentech agreed to
collaborate on the development of such products (the "License").

      On April 29, 1998, the Company and Genentech entered into an amendment to
the Agreement and the License (the "Amendment") to address concerns regarding
compliance with Rule 4460 of the National Association of Securities Dealers,
Inc. (the "NASD"). Rule 4460 requires that stockholder approval be obtained
prior to the issuance, in a transaction other than a public offering, of
securities which are convertible into a number of shares of an issuer's common
stock equal to 20% or more of the common stock outstanding before the issuance
for less than the greater of book or market value of the common stock. The
Preferred Stock is convertible into Common Stock at a price based on the fair
market value of the Common Stock at the time of conversion. However, the NASD
has advised the Company that it regards the day prior to the date of the
Agreement (rather than the date of conversion) as the appropriate date for
measuring the minimum fair market value, which minimum value would be $5.6875.


                                       17
   22

      Rule 4460 also provides that stockholder approval is required before the
issuance of Common Stock when the issuance will result in a change of control of
the issuer. Under the Agreement Genentech is permitted to own up to 40% percent
of the Company's Common Stock. The NASD has advised the Company that ownership
of more than 20% of the Company's outstanding Common Stock may be deemed to
constitute a change in control.


      Because the conversion price of the Preferred Stock will be determined on
the basis of the fair market value of the Common Stock at the time of
conversion, it is mathematically possible that conversion of the Preferred Stock
could result in the issuance of (i) more than a number of shares of Common Stock
equal to 20% or more of the Common Stock outstanding before the issuance for
less than the greater of book or market value of the Common Stock on the date of
the Agreement or (ii) a number of shares of Common Stock sufficient to cause a
change in control within the meaning of Rule 4460.

      The Amendment was entered into to address these issues of compliance with
Rule 4460. The Amendment provides that the conversion price of the Preferred
Stock will never be less than $5.6875, that Genentech will not be allowed to own
more than 19.99% percent of the Company's outstanding Common Stock and that
Genentech will not take or participate in any action the purpose or effect of
which is to change or influence the control of the Company. The Amendment also
provides for changes in the timing and amount of Genentech's funding obligations
under the Agreement and the License that will remain in effect unless and until
the Company's stockholders vote to approve the removal of the limitations
described in the preceding sentence (the "Limitations"). In conjunction with the
execution of the Amendment, the Company agreed to waive certain restrictions on
sale by Genentech of Common Stock contained in the Agreement unless and until
the stockholders vote to approve the removal of the Limitations. See "Effects of
the Amendment."

      This proposal seeks stockholder approval of the removal of the
Limitations. If the stockholders do not approve this proposal, the changes in
Genentech's funding obligations imposed by the Amendment and the waiver of
restrictions on sale will remain in effect.

Effects of the Amendment

      In addition to imposing the Limitations, the Amendment contains the
provisions described below.

      Funding Dates and Amounts

      Pursuant to the Agreement, on December 19, 1997, Genentech purchased
837,314 shares of Common Stock and 939 shares of Series G Preferred Stock. The
Company expects to use the proceeds of the sale of the Common Stock and Series G
Preferred Stock for general corporate purposes. The Agreement provided that
Genentech would purchase an initial $16,000,000 of Series H Preferred Stock on
January 31, 1998 and the balance thereafter in quarterly installments on July 1,
October 1, January 2, and April 1 of each year commencing July 1, 1998 until the
purchase price of Series H Preferred Stock purchased equals the lesser of
$48,000,000 or the Company's development costs for certain products, with the
amount to be purchased at each such quarterly closing to be determined in
accordance with the Company's annual development budget for such products in the
United States. Pursuant to the Agreement, the proceeds of the sale of shares of
Series H Preferred Stock will be used to fund development costs for pimagedine
or second generation products.

      Pursuant to the Amendment, the January 31, 1998 purchase was deferred to
the date which is three days after the Meeting, at which time Genentech will buy
$8,000,000 of Series H Preferred Stock. Unless the stockholders approve this
proposal, the subsequent closing dates will be deferred so that the first
subsequent closing will occur on the earlier of (i) three days after the date on
which the stockholders of the Company subsequently approve the removal of the
Limitations or (ii) 60 days after the date on which data from the Company's
ACTION I trials are unblinded to Genentech (the "Data Release Date").

      Pursuant to its terms, the License is subject to termination by Genentech
upon six months' notice to 


                                       18
   23
the Company. The License provides that in the event of such termination if the
proceeds received by the Company from Genentech's purchase of Series H Preferred
Stock are not sufficient to pay the costs during the six-month termination
notice period of continuing or terminating (as the Company elects) certain then
ongoing development programs, Genentech will pay to the Company in cash an
amount necessary to pay for such costs. The Amendment provides that if notice of
termination of the License is given prior to the Data Release Date, unless the
Company's stockholders have approved removal of the Limitations, Genentech will
be required to pay only the Company's actual costs for the development programs
to the date of the termination notice.

      Restrictions on Sale

      The Agreement provides that for a period of five years from the date of
the Agreement no holder of the Common Stock issued pursuant to the Agreement or
upon the conversion of Preferred Stock will sell a number of shares of Common
Stock which is equal to more than 25% of the average weekly trading volume of
the Common Stock for the four preceding calendar weeks. In conjunction with
execution of the Amendment, the Company agreed to waive these restrictions
unless the stockholders vote to approve the removal of the Limitations.

Terms of the Preferred Stock

      The Preferred Stock has a liquidation value of $10,000 per share plus
accrued dividends ("Liquidation Preference"). In the event of the liquidation of
the Company, holders of the Preferred Stock will be entitled to receive an
amount equal to the Liquidation Preference before any distribution of assets of
the Company to the holders of any class of stock ranking junior to the Preferred
Stock.

      The holders of the Series G and Series H Preferred Stock are entitled to
receive cumulative quarterly dividends, payable in shares of the Series G and
Series H Preferred Stock, respectively, at the per share rate equal to 8.50% in
the case of the Series G Preferred Stock and, in the case of the Series H
Preferred Stock, the prime rate published in The Wall Street Journal five
business days prior to the first issuance of a share of Series H Preferred
Stock. The Certificates of Designations for the Preferred Stock provide that no
dividends will be payable during any period when the holder of the Preferred
Stock and its affiliates beneficially own more than 40% of the outstanding
Common Stock. The Certificates of Designations prohibit the repurchase or
redemption by the Company of shares of stock ranking junior to or on a parity
with the Preferred Stock while there is an arrearage in the payment of
dividends.

      Each share of Series G Preferred Stock is convertible at any time by the
holder thereof upon 70 days' notice to the Company into a number of shares of
Common Stock determined by dividing $10,000 by the average of the closing sales
prices of the Common Stock, as reported on the Nasdaq National Market, for the
20 business days preceding the date of conversion (such average being referred
to as the "Conversion Value"). Each share of Series H Preferred Stock is
convertible on the same terms at any time after the earlier of (i) the granting
of approval by the U.S. Food and Drug Administration (or any successor thereto)
for the marketing and sale of any product which contains as an active ingredient
the compound "Pimagedine" and which is a "Licensed Product" (as such terms are
defined in the License); (ii) termination by Genentech of the License; or (iii)
December 1, 2002. The Preferred Stock is convertible into Common Stock or cash
by the Company on the basis of the Conversion Value. The Certificates of
Designations provide that the Preferred Stock may not be converted into Common
Stock if after such conversion the holder and its affiliates would be the
beneficial owners of more than 40% of the outstanding Common Stock. (Pursuant to
the Amendment, unless the stockholders approve removal of the Limitations, the
Conversion Value may not be less than $5.6875 and the percentage limitation is
19.99% percent). Issuance of Common Stock upon conversion of the Preferred Stock
will have a dilutive effect on holders of the Common Stock.

      Holders of the Preferred Stock generally have no voting rights except as
required by the General Corporation Law of Delaware. However, the affirmative
vote of the holders of a majority of the outstanding Series G or Series H
Preferred Stock is necessary for any amendment of the powers, rights,


                                       19
   24
preferences, or privileges of the Series G or Series H Preferred Stock,
respectively, so as to affect them adversely.

      The Company's Certificate of Incorporation includes a provision that
requires the approval of the holders of 80% of the Company's voting stock as a
condition to a merger or certain other business transactions with, or proposed
by, a holder of 10% or more of the Company's voting stock, except in cases where
certain directors approve the transaction or certain minimum price criteria and
other procedural requirements are met. For purposes of this provision, the
shares of Preferred Stock are not considered to be voting stock.

      The Board of Directors believes that it is in the best interests of the
Company and its stockholders that the Limitations be removed so that the
original terms of the Agreement regarding Genentech's funding obligations and
the limitations on its Common Stock resale rights may continue in effect.

      THE BOARD OF DIRECTORS RECOMMENDS THAT THE STOCKHOLDERS VOTE FOR APPROVAL
OF THE REMOVAL OF THE LIMITATIONS.


          RATIFICATION OF APPOINTMENT OF INDEPENDENT PUBLIC ACCOUNTANTS

      The Board of Directors of the Company has, subject to stockholder
ratification, retained Arthur Andersen LLP to serve as independent public
accountants of the Company for the fiscal year ending December 31, 1998 because
it is an internationally recognized accounting firm familiar with the unique
accounting, tax and financial issues that relate to and affect the
biopharmaceutical industry. Arthur Andersen LLP has a firm-wide effort and a
group of personnel that specialize in this industry and has assigned members of
this group to work with Alteon. Arthur Andersen LLP also served as independent
public accountants of the Company for the fiscal year ended December 31, 1997.

      THE BOARD OF DIRECTORS RECOMMENDS A VOTE FOR THE RATIFICATION OF THE
APPOINTMENT OF ARTHUR ANDERSEN LLP AS THE INDEPENDENT PUBLIC ACCOUNTANTS OF THE
COMPANY FOR THE FISCAL YEAR ENDING DECEMBER 31, 1998.

      One or more representatives of Arthur Andersen LLP is expected to attend
the Meeting and have an opportunity to make a statement and/or respond to
appropriate questions from stockholders.


                       SECTION 16(a) BENEFICIAL OWNERSHIP
                              REPORTING COMPLIANCE

      Section 16(a) of the Securities Exchange Act of 1934, as amended, requires
the Company's officers and directors, and persons who own more than ten percent
of a registered class of the Company's equity securities, to file reports of
ownership and changes in ownership on Forms 3, 4 and 5 with the Securities and
Exchange Commission ("SEC") and the NASD. Officers, directors and greater than
ten percent stockholders are required by SEC regulation to furnish the Company
with copies of all Forms 3, 4 and 5 they file.

      Based solely on the Company's review of the copies of such forms it has
received and written representations from certain reporting persons that they
were not required to file Forms 5 for specified fiscal years, the Company
believes that all its officers, directors, and greater than ten percent
beneficial owners complied with all filing requirements applicable to them with
respect to transactions during fiscal 1997 except Dr. Cerami's Form 4 for
December 1996 for four transactions was filed on April 21, 1997 and Ms. O'Dell's
Form 4 for January 1997 for one transaction was filed on February 12, 1997.

intend to bring any other matters before the Meeting. However, if other matters
