                           HUMAN GENOME SCIENCES, INC.
                              9410 KEY WEST AVENUE
                         ROCKVILLE, MARYLAND 20850-3338

                             PROXY STATEMENT FOR THE
                         ANNUAL MEETING OF STOCKHOLDERS

                             TO BE HELD MAY 14, 1997

         This Proxy Statement is furnished in connection  with the  solicitation
of  proxies  by the Board of  Directors  of Human  Genome  Sciences,  Inc.  (the
"Company") for use at the Annual Meeting of  Stockholders  to be held on May 14,
1997 and at all adjournments of that meeting (the  "Meeting").  All proxies will
be voted in accordance with the instructions  contained in them. If no choice is
specified,  the  proxies  will be voted in favor of the matters set forth in the
accompanying Notice of Meeting. Any proxy may be revoked by a stockholder at any
time before its exercise by delivery of written  revocation  to the Secretary of
the Company.

         On  March  17,  1997,  the  record  date  for  the   determination   of
stockholders  entitled  to vote  at the  Meeting,  there  were  outstanding  and
entitled to vote an aggregate of  18,870,460  shares of common  stock,  $.01 par
value per share ("Common Stock"), of the Company. Only shareholders of Record as
of March 17, 1997 are entitled to vote at this  Meeting.  Each share is entitled
to one vote.

         The Company's Annual Report for the fiscal year ended December 31, 1996
is being  mailed to  stockholders  with the  mailing  of this  Notice  and Proxy
Statement beginning on or about April 24, 1997.


VOTES REQUIRED

         A  majority  of the  issued  and  outstanding  shares of  Common  Stock
entitled to vote  constitutes a quorum at the Meeting.  The affirmative  vote of
holders of the majority of shares of Common Stock which are present and entitled
to vote are required to approve  Proposal 2. The affirmative  vote of holders of
at least the  majority of the shares of Common  Stock which are entitled to vote
at the Meeting is required to approve Proposal 3. Therefore,  failure to vote on
any of these proposals has the same effect as a negative vote.  Accordingly,  if
stockholders do not vote their shares for Proposals 2 and 3, either in person or
by proxy,  such  stockholders will have effectively voted against the Proposals.
If approved,  Proposal 3 will become  effective upon the filing of a Certificate
of  Amendment  to the  Certificate  of  Incorporation  of the  Company  with the
Secretary of State of Delaware,  which is expected to follow  shortly  after the
approval, if at all, of Proposal 3.

         Shares of Common Stock represented in person or by proxy at the Meeting
(including shares that abstain or do not vote with respect to one or more of the
matters  presented  at the  Meeting)  will be  tabulated  by the  inspectors  of
election  appointed for the Meeting whose  tabulation will determine  whether or
not a quorum is present.  Abstentions will be counted as shares that are present
and entitled to vote for purposes of  determining  the presence of a quorum with
respect to any matter, but will not be counted as votes in favor of such matter.
Accordingly,  an abstention from voting on a matter by a stockholder  present in
person or represented by proxy at the Meeting will have the same legal effect as
a vote  "against"  the  matter.  If a  broker  holding  stock in  "street  name"
indicates on the proxy that it


<PAGE>



does not have discretionary  authority as to certain shares to vote on a matter,
those shares will not be considered as present and entitled to vote with respect
to that  matter.  Accordingly,  a "broker  non-  vote" on a matter  will have no
effect on the voting on such matter.

         Candidates  for  election  as  members  of the Board of  Directors  who
receive the highest number of votes, up to the number of directors to be chosen,
shall  stand  elected,  and an  absolute  majority  of the  votes  cast is not a
prerequisite to the election of any candidate to the Board of Directors.

         The  following  table  sets  forth,  as of March 17,  1997  (except  as
otherwise  footnoted  below),  certain  information  regarding  the ownership of

                       PROPOSAL 1 - ELECTION OF DIRECTORS

         It is proposed to elect 11 directors  of the  Company.  Each nominee is
currently a director of the Company.  At the Meeting,  the persons  named in the
enclosed proxy will vote to elect the directors  listed below,  unless the proxy
is marked  otherwise.  Each of the nominees has indicated his or her willingness
to serve,  if elected;  however,  if any nominee should be unable to serve,  the
proxies  may be  voted  for a  substitute  nominee  designated  by the  Board of
Directors.

         If the amendment to the Certificate of  Incorporation  to provide for a
Classified  Board of  Directors  (see  "PROPOSAL  3") is  adopted,  the Board of
Directors  will be divided  into three  classes.  This Meeting will be the first
election of directors  after the amendment  which created the Classified  Board.
Accordingly, at the Meeting, three directors will be elected for a term expiring
at the Company's 1998 Annual  Meeting,  four directors for terms expiring at the
1999 Annual  Meeting,  and four directors for a term expiring at the 2000 Annual
Meeting  and,  in each  case,  until  their  successors  are  duly  elected  and
qualified.  At each  Annual  Meeting  after 1997,  directors  will be elected to
succeed those directors whose terms then expire, and each person so elected will
serve for a three-year term.

         If the Amendment to the Certificate of  Incorporation  is not approved,
directors elected at the Meeting will serve one-year terms until the 1998 Annual
Meeting and until their successors are duly elected and qualified.

         SmithKline Beecham has the right to designate a nominee pursuant to the
terms of the Series B Convertible  Preferred  Stock Purchase  Agreement (the "SB
Stock Purchase Agreement") and has designated Robert A. Armitage as its nominee.
SmithKline   Beecham's  right  to  designate  a  nominee   continues  until  the
termination  for  certain  specified  reasons as  defined  in the  Collaboration
Agreement or the later of (i) expiration of the initial  research term under the
Collaboration   Agreement  or  (ii)  the  date  on  which   SmithKline   Beecham
beneficially owns less than 5% of the Company's Common Stock (on a fully diluted
basis).  For a  description  of  the  Collaboration  Agreement,  see  "EXECUTIVE
COMPENSATION AND OTHER MATTERS--Certain Relationships and Related Transactions."

BOARD AND COMMITTEE MEETINGS

         The Board of Directors  held a total of four meetings  during 1996. Dr.
Link was unable to attend two meetings.

         The EXECUTIVE  COMMITTEE was  established to act on most matters during
the intervals  between Board meetings.  It has all the authority of the Board in
overseeing the business and affairs of the Company,  except those powers that by
law cannot be delegated by the Board of Directors.  The Executive Committee held
nine committee  meetings during the 1996 fiscal year and currently consists of 5
directors: Drs. Haseltine and Cavanaugh and Messrs. Booth, Johnston, and Ruch.

         The AUDIT COMMITTEE provides the opportunity for direct contact between
the Company's  independent  accountants and the Board. The Audit Committee makes
recommendations  concerning the engagement of  independent  public  accountants,
reviews with the  independent  public  accountants  the plans and results of the
audit engagement,  and reviews the adequacy of the Company's internal accounting
controls.  The Audit Committee,  which currently  consists of Mr.  Johnston,  as
Chairman,  Mrs. Sills-  Greenough,  and Mr. Hormats held two meetings during the
1996 fiscal year.

         The COMPENSATION  COMMITTEE determines all compensation paid or awarded
to the Company's  executive officers and senior officers (those with the rank of
vice  president or above) and  administers  the  Company's  1993  Incentive  and
Non-Qualified  Stock Option Plan and the 1994 Stock  Option Plan (the  "Plans"),
for which all employees and certain non-employees are eligible. The Compensation
Committee held eleven  meetings during the 1996 fiscal year. The current members
of the Compensation  Committee are Dr. Cavanaugh and Messrs. Ruch, and Johnston,
as Chairman.

         The NOMINATING  COMMITTEE  consists of three directors:  Drs. Haseltine
and Cavanaugh, and Mr. Johnston. The committee held two meetings during the 1996
fiscal year. The committee is responsible for proposing a slate of directors for
election by the shareholders at each annual meeting and proposing  candidates to
fill any vacancies on the Board. The committee will consider candidates proposed
by shareholders for Board membership.

THE BOARD OF  DIRECTORS  RECOMMENDS  A VOTE FOR THE  ELECTION  OF THE  NOMINATED
DIRECTORS.

        PROPOSAL 2 - APPROVAL OF AMENDMENTS TO THE 1994 STOCK OPTION PLAN

         On  November  6, 1996 and  January  21,  1997,  the Board of  Directors
approved amendments to the 1994 Stock Option Plan of Human Genome Sciences, Inc.
(as amended the "1994 Plan"),  contingent  upon approval by the  stockholders at
the Meeting. The amendments increased the number of shares available

                                     - 11 -

<PAGE>



for issuance  under the 1994 Plan from  2,450,000 to 3,450,000  and provides for
automatic  grants  for non-  employee  directors.  The 1994  Plan,  prior to the
Amendment being submitted to the Stockholders hereby, prohibited grants of stock
options to members of the Stock Option Committee. This provision was included in
the 1994 Plan to meet the  requirements  of the Rule 16b-3 under the  Securities
Exchange  Act of 1934 as then in  effect.  As a result  of an  amendment  to the
Securities  Exchange Act of 1934, this restriction is no longer required.  As of
March 17, 1997,  2,191,945 shares are subject to outstanding  options issued and
106,705  options are available for grant (prior to the increase  pursuant to the
Amendments).  In addition, the Company maintains a 1993 Stock Option Plan, under
which  224,554  shares are  subject  to  outstanding  options  issued and 59,134
options are available for grant. The purpose of the 1994 Plan, as amended, is to
enable  the  Company  to  attract,  retain,  and  motivate  the  best  available
individuals  to serve as officers and employees of the Company and as members of
its Board of Directors.

         The 1994  Plan,  as  amended,  provides  for the  issuance  of  options
covering  up to  3,450,000  shares  of  Common  Stock,  subject  to  appropriate
adjustments in the event of stock splits, stock dividends,  and similar dilutive
events.   Options  may  be  granted  under  the  1994  Plan  to  all  employees,
non-employee directors,  independent contractors, and consultants of the Company
in the discretion of the Compensation Committee. As of March 28, 1997 there were
approximately  290  employees  of the  Company  and 7 others  eligible  for such
grants.

         Options granted may be either  "incentive stock options" (as defined in
Section 422 of the Internal  Revenue Code (the  "Code")) or  nonqualified  stock
options.  The exercise  price of each option is determined  by the  Compensation
Committee at the time of the grant,  provided that the exercise price of options
may not be less than the fair market value of the company's  Common Stock on the
date of the grant.

         The term of each option and the  increments in which it is  exercisable
are  determined by the  Compensation  Committee,  provided that no option may be
exercised (i) more than ten years of after the date of the grant, (ii) more than
three months after termination of an optionee's employment or other relationship
with the  Company,  or (iii) more than 12 months  after an  optionee's  death or
disability.  In addition,  if an optionee owns more that 10% of the total voting
power of all  classes  of the  Company's  stock at the  time the  individual  is
granted an incentive  stock option,  the exercise price per share cannot be less
than 110% of the fair market value on the date of the grant, and the term of the
incentive stock option cannot exceed five years from the date of the grant.  The
Compensation  Committee may provide that certain options will become exercisable
in  increments  based  primarily or  exclusively  on the  attainment  of certain
performance  goals.  No option may be granted  under the 1994 Plan more than ten
years  after  the  date of the  adoption  of the  1994  Plan.  The  options  are
non-transferable during the life of the option holder.

         The 1994 Plan, as amended,  provides for automatic grants of options to
purchase  10,000  shares  of Common  Stock on the date  that  each  non-employee
director is first  elected or appointed as a director and an automatic  grant of
an option to purchase 2,000 shares of Common Stock to each non-employee director
on the date immediately following the Annual Meeting of Stockholders, commencing
on the day immediately  following the date of the annual meeting of stockholders
for the company's  fiscal year ending  December 31, 1996. The exercise price for
each share subject to a Director  Option shall be equal to the fair market value
of the Common Stock on the date of grant.  Initial director options shall become
exercisable in five equal annual installments  commencing one year from the date
of the option is granted and annual automatic grants will become  exercisable in
full on the first anniversary of the date of grant.

                                     - 12 -

<PAGE>



Options  will  expire the earlier of 10 years after the date of grant or 90 days
after the termination of the director's association with the Company.

         Upon the  occurrence of certain  events,  including the  acquisition by
another  corporation or person of shares of Common Stock  representing more than
80% of the voting power of the Common Stock or a sale of  substantially  all the
property of the  Company,  the options  granted  under the 1994 Plan will become
fully  exercisable  for a period  of time  determined  by the  Company  and will
terminate if not exercised within that period of time, unless separate provision
is made by the successor for their continuance.

         The Company  intends that the 1994 Plan qualify as a plan  described in
Rule 16b-3 ("Rule 16b-3") of the Securities  Exchange Act of 1934 (the "Exchange
Act").  Grants of options under the 1994 Plan will  therefore be exempt from the
short-swing profit rules of Section 16(b) of the Exchange Act. The 1994 Plan may
be amended by the Board of Directors,  consistent with Rule 16b-3,  and the 1994
Plan specifically authorizes the Board of Directors to make any amendment deemed
necessary or advisable to ensure that incentive  stock options and  nonqualified
stock options continue to be treated as such, respectively, under all applicable
laws.

         THE  BOARD  OF  DIRECTORS  RECOMMENDS  A VOTE FOR THE  APPROVAL  OF THE
AMENDMENTS TO THE 1994 STOCK OPTION PLAN.

PROPOSAL 3         - CLASSIFICATION OF THE BOARD OF DIRECTORS AND RELATED
                      PROPOSAL

         The Board of Directors has approved a resolution amending the Company's
Certificate of  Incorporation to provide for a classified Board (the "Classified
Board") and to establish procedures for filling vacancies on the Board. The text
of the proposed  amendment is attached to this Proxy Statement as Exhibit A. The
statements made in this Proxy Statement with respect to these amendments  should
be read in conjunction  with and are qualified in their entirety by reference to
Exhibit A.

         Proposal 3 would,  if  adopted,  operate to divide the Board into three
separate classes of directors, as nearly equal in number as possible, to serve a
three year term and until their  successors  are duly elected and qualified with
each class being elected at different annual stockholder meetings. Following the
effectiveness  of Proposal 3, Class I directors  will consist of four  directors
who will serve for an  initial  term of three  years,  Class II  directors  will
consist of four  directors who will serve for an initial term of two years,  and
Class III  directors  will  consist  of three  directors  who will  serve for an
initial term of one year. For an  identification of these nominees see "PROPOSAL
1 - ELECTION OF DIRECTORS". At each annual meeting after 1997, directors will be
elected to succeed those whose terms then expire and each newly elected director
will serve for a three-year term. Proposal 3 would replace the present system of
electing all of the directors annually for one-year terms.

         The  effect  of a  Classified  Board  of  Directors  may  otherwise  be
circumvented  by  increasing or  decreasing  the size of the Board.  At present,
vacancies  in the Board of  Directors,  including  vacancies  resulting  from an
increase  in the number of  directors,  are  required to be filled by a majority
vote of the remaining  members of the Board,  although  less than a quorum,  and
each person so elected  serves as a director until a successor is elected by the
stockholders.  Additionally, the size of the Board may be increased or decreased
at any time by the  affirmative  vote of holders  representing a majority of the
Company's  outstanding  voting  stock,  except  that  the  term of an  incumbent
director cannot be shortened.

                                     - 13 -

<PAGE>



Proposal 3 provides  that the size of the Board may be fixed solely by action of
the Board  itself,  and that any vacancies in the Board of Directors can only be
filled by a majority vote of the remaining directors then in office, even though
less than a quorum,  and each  person so elected  would  serve  until the annual
meeting of  stockholders at which the class of directors for which he or she has
been chosen is elected.  If the number of  directors  constituting  the Board is
increased or decreased,  the resulting  number of directors  will be apportioned
among the three  classes so as to make all classes as nearly  equal in number as
possible,  except that the term of any incumbent  director may not be shortened.
In addition, under the applicable provisions of the Delaware General Corporation
Law ("GCL"),  as a result of the establishment of a Classified Board,  directors
may only be removed for cause.

         Adoption of Proposal 3 may have the effect of making it more  difficult
for  stockholders  to remove the  existing  management  of the  Company and may,
therefore, discourage potentially unfriendly bids for shares of the Company. The
amendment  may also impede  assumption  of the  management of the Company by any
other person or entity which, through a takeover bid or otherwise,  might obtain
a  substantial  number  of  shares  of  Common  Stock.  Proposal  3 is not being
recommended  in  response  to any past  problems  regarding  Board  of  Director
continuity  or any  specific  effort of which the Board of Directors is aware to
accumulate the Company's stock or to acquire control of the Company,  but rather
in recognition  that such activities  might occur in the future.  In considering
Proposal 3, stockholders should consider and review the "REASONS FOR PROPOSAL 3"
and "POSSIBLE ANTI-TAKEOVER EFFECTS OF THE PROPOSAL 3".

         THE BOARD OF DIRECTORS  RECOMMENDS A VOTE FOR THE CLASSIFICATION OF THE
BOARD OF DIRECTORS AND FOR THE ADOPTION OF PROPOSAL 3.


REASONS FOR PROPOSAL 3

         The Board of  Directors  believes  that  Proposal  3 will  enhance  the
ability of the Company to carry out long-range plans and goals for the Company's
benefit and the benefit of its stockholders.  Proposal 3 will promote these long
range plans and goals since, if adopted,  it would establish a Classified Board,
creating  directorships  for longer terms which  expire at different  intervals.
Although the Company has not experienced difficulties in the past in maintaining
continuity of operations and management,  the Board of Directors believes that a
Classified Board will assist the Company in maintaining this continuity into the
future.  These  provisions  should  increase the  likelihood of  continuity  and
stability in the  composition  of the Board of Directors  and, at the same time,
reduce the  possibility  that a third party could effect or threaten to effect a
sudden or surprise change in majority control of the Board of Directors  without
the support of the incumbent Board. The Board of Directors does not believe that
the  Company  has had any  problems in the past with  respect to  continuity  in
leadership and policy.

         A  Classified  Board  would  also  extend  the time it would take for a
hostile  stockholder  to obtain  control of the  Company's  Board of  Directors,
thereby  limiting such abusive  takeover  tactics as two tiered  tender  offers.
Assuming each class of directors is equal in size,  even a majority  stockholder
could not obtain  control  of the Board  until the  second  annual  stockholders
meeting after it acquired a majority of the voting stock.  During this time, the
Board of Directors  would have a better  opportunity  to negotiate with any such
majority  stockholder to obtain more favorable  price and terms in any merger or
tender  offer.  In  addition,  Proposal  3 will  eliminate  the  ability  of the
stockholders  to dismiss  the  entire  Board of  Directors 

                                     - 14 -

and to increase or decrease the size of the Board, and will, therefore,  further
promote continuity of operations and management.

POSSIBLE ANTI-TAKEOVER EFFECTS OF PROPOSAL 3.

         Proposal 3 is intended to encourage  persons seeking to acquire control
of the Company to initiate such an acquisition through arm's length negotiations
with the Company's Board of Directors.  The Board of Directors  believe that the
adoption  of  Proposal 3 will  enable the Board of  Directors  to  evaluate  the
proposal  and  study  alternative  proposals  in the  absence  of  the  coercive
atmosphere  that might  otherwise  prevail and without  the  imminent  threat of
removal.  This ability to evaluate and negotiate  will help ensure that the best
price  is  obtained  in any  acquisition  transaction  that  may  ultimately  be
consummated.

         Proposal 3 cannot, and is not intended to, prevent a purchase of all or
a majority of the equity  securities  of the Company nor is it intended to deter
bids or other efforts to acquire such securities. Rather, the Board of Directors
believes that Proposal 3 will encourage  third parties which may seek to acquire
control of the  Company to initiate  such an  acquisition  through  negotiations
directly with the Board of Directors. Therefore, the Board believes that it will
be in a better  position to protect the interests of all of the  stockholders if
Proposal 3 is approved. In addition, the stockholders of the Company will have a
more meaningful opportunity to evaluate such action.

         Adoption of Proposal 3 may deter certain mergers,  tender offers, proxy
contests  or other  future  takeover  attempts  which  holders of some or even a
majority of the outstanding stock believe to be in their best interests, and may
make  removal  of  management  more  difficult  even if such  removal  would  be
beneficial  in the judgment of many of the  stockholders.  Not all  takeovers or
changes in control of the Board of  Directors  that are  proposed  and  effected
without  prior  consultation  and  negotiation  with  the  incumbent  Board  are
necessarily detrimental to the Company and its stockholders.  However, the Board
believes  that the benefits of seeking to protect its ability to negotiate  with
the proponent of an unfriendly or unsolicited proposal to acquire or restructure
the Company outweigh the disadvantages of discouraging such proposals.

         Although Proposal 3 is intended to encourage persons seeking to acquire
control of the Company to initiate  such an  acquisition  through  arm's  length
negotiations  with the Board the overall  effect of these  provisions  may be to
discourage  a third party from making a tender offer for a portion or all of the
Company's securities,  hostile or otherwise (including an offer at a substantial
premium over the then prevailing market value of the Company's Common Stock), or
otherwise  attempting to obtain a substantial portion of the Common Stock of the
Company in order to commence a proxy contest or engage in other takeover-related
action,  even  though  some or a majority of the  Company's  stockholders  might
believe such actions to be  beneficial.  If third parties are  discouraged  from
making  offers for all or a substantial  portion of the Company's  Common Stock,
the effect may be to dampen demand for, or speculation in, the Company's  Common
Stock and therefore negatively impact the price of the Common Stock.

         To the extent that any third party potential  acquirors are deterred by
Proposal 3, such provisions may serve to benefit incumbent  management by making
it more  difficult  to  remove  management,  even when the only  reason  for the
proposed change of control or the stockholder  action may be the  unsatisfactory
performance of the present directors. In addition, since Proposal 3 is, in part,
designed  to  discourage  accumulating  large  blocks  of the  Company's  voting
securities by purchasers whose objective is

                                     - 15 -

<PAGE>



to gain  control  of the  Company,  their  adoption  could  tend to  reduce  the
temporary  fluctuation in the market price of such voting stock that  frequently
results  from  such  accumulations  or  attempted  accumulations.   Accordingly,
stockholders could be deprived of certain  opportunities to sell their shares at
a higher market price.

RELATIONSHIP OF PROPOSAL 3 TO OTHER PROVISIONS

         Existing  provisions of the Delaware GCL and the Company's  Certificate
of  Incorporation  may be deemed to discourage  unsolicited  takeover  proposals
regardless of the adoption or rejection of the Proposals. Although the Company's
current Certificate of Incorporation does not contain provisions intended by the
Company  to have,  or to the  knowledge  of the Board of  Directors  having,  an
anti-takeover  effect, it currently authorizes the issuance of 50,000,000 shares
of Common  Stock and  1,000,000  shares of  Preferred  Stock.  The Board has the
authority to fix by resolution the designations,  powers,  preferences,  rights,
qualifications,  limitations or restrictions  on the shares of Preferred  Stock.
This authorized and available Common Stock and Preferred Stock could (within the
limits imposed by applicable law and the rules of the NASDAQ National Market) be
issued by the Company and used to discourage a change in control of the Company.
For example,  the Company could privately place shares with purchasers who might
side with the Board of Directors in opposing a hostile  takeover.  Additionally,
the Board could designate a series of Preferred Stock to be issued in connection
with a rights plan. In addition,  the Company's By-laws  currently  restrict the
calling of a special  meeting to the Board of  Directors,  the  President or the
Secretary at the request of shareholders of a majority of the voting stock.  The
provision could make it more difficult for a party seeking to acquire control to
call a meeting for the election of directors or to take other desired  corporate
action.

         Once a Classified  Board is  established,  the  Delaware GCL  prohibits
stockholders  from removing  members of a Classified  Board without cause before
the expiration of their respective terms unless the Certificate of Incorporation
specifies  otherwise.  The Delaware  GCL  contains a number of other  provisions
which are  designed to  strengthen  the  position  of  incumbent  management  in
connection with a takeover  attempt.  For example,  Delaware law provides that a
corporation  has the general power,  exercisable  by its board of directors,  to
accept, reject, respond to or take no action in respect of an actual or proposed
acquisition,  divestiture,  tender offer,  takeover or other fundamental change.
The case law of Delaware has developed special standards for deciding whether to
uphold or  advocate  the  actions  of  incumbent  management  in the  context of
takeover proposals.

         The Company is also subject to Section 203 of the Delaware  GCL,  which
provides  that a  person  who  acquires  fifteen  percent  (15%)  or more of the
outstanding  voting  stock of a  Delaware  corporation  becomes  an  "interested
stockholder".  Section 203 prohibits a  corporation  from engaging in mergers or
certain  other  "business  combinations"  with an interested  stockholder  for a
period of three (3) years,  unless (i) prior to the date the stockholder becomes
an interested  stockholder,  the board of directors approves either the business
combination  or the  transaction  which results in the  stockholder  becoming an
interested  stockholder;  or (ii) the interested  stockholder is able to acquire
ownership of at least eight-five  percent (85%) of the outstanding  voting stock
of the corporation  (excluding  shares owned by directors of the corporation who
are also officers and shares owned by certain  employee stock plans) in the same
transaction by which the stockholder became an interested stockholder;  or (iii)
the interested stockholder obtains control of the board of directors, which then
approves a business  combination which is authorized by a vote of the holders of
two-thirds  of  the  outstanding   voting  stock  not  held  by  the  interested
stockholder.


                                     - 16 -

<PAGE>



         The definition of interested stockholder does not include persons whose
ownership  of voting  stock  exceeds the fifteen  percent  (15%)  threshold as a
result of action taken by the corporation unless that person thereafter acquires
additional shares.

         A "business  combination"  is defined  broadly in the  Delaware  GCL to
include any merger or consolidation with the interested stockholder,  any merger
or  consolidation  caused by the  interested  stockholder in which the surviving
corporation will not be subject to Delaware law, or the sale,  lease,  exchange,
mortgage, pledge, transfer or other disposition to the interested stockholder of
any assets of the corporation having a market value equal to or greater than ten
percent  (10%) of the aggregate  market value of the assets of the  corporation.
"Business  combination"  is also  defined to include  transfers  of stock of the
corporation or a subsidiary to the interested  stockholder (except for transfers
in  conversion,  exchange or pro rata  distribution  which do not  increase  the
interested  stockholder's  proportionate ownership of a class or series), or any
receipt by the interested stockholder (except  proportionately as a stockholder)
of any loans, advances, guaranties, pledges or financial benefits.

        PROPOSAL 4 - RATIFICATION OF APPOINTMENT OF INDEPENDENT AUDITORS

         The Board of Directors is seeking  ratification  of the  appointment of
Ernst & Young,  LLP as its  independent  auditors  for 1997.  If a  majority  of
stockholders  voting at the Meeting  should not approve the selection of Ernst &
Young,  LLP, the selection of independent  auditors may be  reconsidered  by the
Board of Directors.

         Ernst & Young, LLP is currently the Company's  independent  auditor.  A
representative  of Ernst & Young,  LLP is  expected  to attend the  Meeting  and
respond to appropriate questions from stockholders.

         THE  BOARD  OF  DIRECTORS  RECOMMENDS  A VOTE FOR  RATIFICATION  OF THE
APPOINTMENT OF ERNST & YOUNG, LLP.

                    EXECUTIVE COMPENSATION AND OTHER MATTERS

COMPENSATION OF DIRECTORS

         In 1996,  each  director  who was not an  employee  of the  Company,  a
consultant to the company,  or associated with a collaborator of the Company was
eligible  to receive a  director's  fee of  $25,000  per year.  Other  directors
received no  compensation  for their services to the Company as directors.  Each
non-employee  director is also  entitled to receive  (i) an  automatic  grant of
options  to  purchase  10,000  shares  of  Common  Stock on the date  that  each
non-employee  director is first  elected or  appointed as a director and (ii) an
annual  automatic  grant of an option to purchase  2,000 shares of Common Stock.
See "PROPOSAL  2-APPROVAL  OF  AMENDMENTS  TO THE 1994 STOCK OPTION  PLAN".  All
directors are  reimbursed  for expenses  incurred in connection  with  attending
meetings of the Board of Directors.

         In September 1992, the Company entered into a consulting agreement with
Donald D. Johnston,  a director of the Company, for an initial term of one year.
This  agreement  was renewed for  additional  one year terms in September  1993,
1994,  1995 and  1996.  Pursuant  to the  agreement,  Mr.  Johnston  received  a
consulting  fee of $50,000 in the year ended August 31, 1996.  Compensation  for
the year ending August 31, 1997 will be $1 in addition to the standard directors
fee of $25,000.  In connection  with entering into the September 1992 agreement,
the Company sold 56,391 shares of restricted  Common Stock to Mr.  Johnston at a
purchase  price of $.01 per share.  All of the  shares are  subject to rights of
first  refusal  on sale (at a price of $.19 per share  less than the price to be
paid in the proposed sale.)

         In August,  1996 the Company  granted Mr.  Hormats  options to purchase
11,250  shares of Common Stock at $32.25 per share.  The options vest and become
exercisable in equal annual installments over a five-year period.

EMPLOYMENT AGREEMENTS

         In February 1997, the Company  entered in an employment  agreement with
Dr. Haseltine that superseded his May 1993 employment agreement.  The employment
agreement  is  for  an  initial  term   expiring  in  February   2000  and  will
automatically extend for additional one-year periods unless terminated by either
party  four  months  prior to the end of the  applicable  term.  The  employment
agreement  provides  that Dr.  Haseltine is entitled to an annual base salary of
$350,000,  and an annual bonus as determined by the Board of Directors and a car
allowance  of  $10,200  per year.  The  Company  may  terminate  the  employment
agreement  without  cause,  and upon such  termination,  Dr.  Haseltine  will be
entitled to  severance  equal to his base salary for a period of 24 months.  The
Company sold to Dr. Haseltine  661,160 shares of restricted  Common Stock on May
18, 1993 at a purchase price of $.20 per share.  The shares of Common Stock sold
to Dr. Haseltine vest in equal annual  installments over a four-year period that
commenced on May 11, 1993.  Unvested shares may be repurchased by the Company at
cost if Dr.  Haseltine is terminated for cause or if Dr.  Haseltine  voluntarily
terminates  his  employment.  All of the shares  are  subject to rights of first
refusal by the  Company  on sale (at a price per share  equal to $1.13 less than
the price of the proposed sale).

         In June 1995, the Company entered into an employment agreement with Mr.
Booth in which he agreed to serve as President  and Chief  Operating  Officer of
the  Company.  The  Company may  terminate  the  agreement  at any time and upon
termination  without  cause,  Mr.  Booth will be entitled to receive base salary
until the earlier of (i) eighteen  months after  termination of  employment,  or
(ii)  until  Mr.  Booth  commences  other  regular,  full-time  employment.  The
agreement  provides  that Mr.  Booth is entitled to an annual  base  salary,  as
determined by the Board of Directors ($325,000 as of January 1, 1997), an annual
bonus of up to 35% of base salary,  and a car allowance of $9,000 per year.  The
Company paid Mr. Booth a sign-on payment of $60,000.  The Company paid Mr. Booth
relocation costs of $423,725 in connection with his relocation to Maryland.

         In October 1992, the Company entered into an employment  agreement with
Dr. Rosen in which Dr. Rosen agreed to serve as Senior Vice President,  Research
and Development of the Company. The employment agreement was for an initial term
ending  in  October  1995 and has been and will be  automatically  extended  for
additional  one-year periods unless  terminated by either party prior to the end
of the  applicable  term.  Dr.  Rosen is entitled to an annual base  salary,  as
determined by the Board of Directors ($275,000 as of January 1, 1997), an annual
bonus of between 10% and 20% of his base salary,  and a car  allowance of $4,800
per year. The Company may terminate the employment  agreement without cause, and
upon such termination,  Dr. Rosen will be entitled to receive three months' base
salary. In April 1993, pursuant to the agreement,  the Company sold to Dr. Rosen
140,977 shares of restricted Common Stock at a purchase price of $.01 per share.
All of the shares are subject to rights of first  refusal by the Company on sale
(at a price per share equal to $.19 less than the price of the proposed sale).

         In March 1994,  the Company  entered into an employment  agreement with
Mr.  Lorimier  in which he agreed to serve as Senior  Vice  President,  Business
Development of the Company. The employment agreement was for a term ending March
1997. The  employment  agreement  provided that Mr.  Lorimier was entitled to an
annual base salary,  as  determined  by the Board of  Directors  ($250,000 as of
January 1, 1997),  and an annual  bonus,  based on his  performance,  of between
$50,000  and  $100,000.  On  February  13,  1997,  the  Company  entered  into a
Retirement Agreement with Mr.

                                     - 22 -

<PAGE>



Lormier.  Pursuant to the  Retirement  Agreement,  Mr.  Lormier,  i) will retire
effective June 30, 1997,  ii) has resigned as a director,  iii) will be entitled
to payment of a pro rata bonus based on performance  between January 1, 1997 and
his retirement date and iv) will be retained as a part-time consultant for a one
year period for compensation of $50,000 for such year. The Retirement  Agreement
provides for the  acceleration  of the vesting of 40,000 unvested shares subject
to an option  granted to Mr.  Lormier on March 21, 1994 at an exercise  price of
$17.50 and further  provides  that the option shall be  exercisable  through the
date which is 90 days following the expiration of the consulting period.

         In   March   1994,   Dr.   Antonaccio   agreed   to   serve   as   Vice
President-Strategic  Drug  Development of the Company for an annual base salary,
as determined by the Board of Directors ($215,000 as of January 1, 1997).

LOANS TO EXECUTIVE OFFICERS

         In November 1993, the Board of Directors authorized the extension of an
interest-free  loan to Dr. Haseltine,  in an amount up to $1,000,000,  to enable
Dr. Haseltine to pay certain tax liabilities  relating to his purchase of Common
Stock in May 1993. The loan was made on December 29, 1993 and was evidenced by a
promissory  note dated  March 4, 1994 in the  amount of  $872,845,  replacing  a
promissory  note dated  December 29, 1993. The loan was increased to $891,488 on
December 16, 1994.  The loan was secured  initially by 114,472  shares of issued
and outstanding Common Stock of the Company,  whose market value at the time the
Common Stock was pledged was equal to 200% of the principal sum of the loan (the
"Collateral")  and is now secured by 64,252 shares of Common Stock.  The loan is
repayable in full (i) twenty  business  days after demand for repayment has been
made,  (ii)  twenty  business  days after Dr.  Haseltine's  employment  has been
voluntarily  terminated by Dr. Haseltine or terminated for cause by the Company,
(iii) on the date Dr. Haseltine defaults on the note, or (iv) December 29, 2003,
whichever occurs first. Dr. Haseltine is required to prepay the loan in full, or
in some  instances,  in  part,  if he sells  any of the  Collateral  or  Company
terminates  his  employment  as a result of his death or  disability  or for any
reason other than for cause.

COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION

         The Compensation  Committee of the Board of Directors (the "Committee")
consists  entirely of  non-employee  directors.  The  Committee  determines  all
compensation  paid or awarded to the Company's  executive  officers and approves
the Company's overall compensation policies.

         The  Committee's  goals are attract and retain an executive  management
team that is capable of taking full  advantage of the  Company's  opportunities,
and to provide  incentives for  outstanding  performance.  The Committee takes a
flexible and  individualized  approach,  with a minimum of formal structure.  In
arriving  at an  initial  compensation  offer to an  individual,  the  Committee
considers  determinants of the individual's market value,  including experience,
education,   accomplishments   and   reputation,   as  well  as  the   level  of
responsibility  to  be  assumed,  in  relation  to  the  market  value  of  such
qualifications.  When  determining  subsequent  adjustments  to  an  individuals
compensation   package,   the  Committee   also   evaluates  the  importance  to
shareholders  of that  person's  continued  service,  based  largely  on  recent
accomplishments. This is a judgment process, exercised by the Committee with the
advice of Company  Management and a compensation  consultant.  The evaluation is
not tightly linked to performance against predetermined  criteria,  because such
systems interfere with creative opportunism.

         The executive  officers'  compensation  structure consists of: (i) base
salary, (ii) cash bonus and (iii) stock options.

         BASE  SALARY.  Each  individual's  base  salary  is  determined  by the
Committee  after  considering a variety of factors that make up market value and
prospective  value to the  Company,  including  the  knowledge,  experience  and
accomplishments of the individual, his level of responsibility,  and the typical
compensation levels for individuals with similar credentials.  The Committee may
change the salary of an  individual on the basis of its judgment for any reason,
including  the  performance  of  the  individual  or  the  Company,  changes  in
responsibility,   and  changes  in  the  market  for  executives   with  similar
credentials.

         CASH BONUS.  Bonus is for  accomplishments  during the past year. It is
determined by the Committee with advise from Company Management,  based upon the
Committee's  assessment  of the  individual's  contributions  during  the  year,
compared  to,  but not  limited  to,  a list of  goals  previously  approved  by
Management and the Committee.  In determining  bonuses for the fiscal year ended
December 31, 1996,  the  Committee  considered  the  establishment  of seven new
collaborations with other companies based on HGS technology,  continued progress
within  collaborations  previously  established,  progress in defining  possible
therapeutic  proteins for internal  development  or  out-licensing,  and further
additions  to the  Company's  intellectual  property  and to its  capability  to
convert this to product development programs.

         STOCK  OPTIONS.  Stock  options are  prospective  incentives,  aimed at
keeping and motivating key people by letting them share in the value they create
for stockholders.  They are awarded at times deemed appropriate by the Committee
in  amounts  calculated  to  secure  the  full  attention  and best  efforts  of
executives  on whose  future  performance  the  Company's  success  will depend.
Executive  officers other than the C.E.O.  (discussed below) received options on
210,000 shares in 1996, including one initial award.


                                     - 24 -

<PAGE>



         The  Committee  also  believes   significant  equity  participation  is
important   in   attracting   capable   and   entrepreneurial   scientists   and
administrators, so 580,616 shares were optioned to other managers and scientists
in 1996, pursuant to employee incentive plans approved by the Committee.

         CHIEF  EXECUTIVE  OFFICER'S  COMPENSATIONS.  The Committee  awarded Dr.
Haseltine a bonus of $150,000 for the fiscal year ended  December  31, 1996.  In
addition,  effective January 1, 1997, Dr.  Haseltine's base salary was increased
from  $330,000 per year to $350,000  per year.  The bonus and increase in salary
are  based  on the  Committee's  assessments  of  Dr.  Haseltine's  role  in the
Company's   performance  in  1996,   and  on  the   continuing   growth  in  his
responsibilities.  Under Dr. Haseltine's leadership,  the Company's capabilities
and opportunities were significantly enhanced by initiating collaborations which
multiply the potential for converting the Company's discoveries into products on
a timely basis. At the same time, the Company has negotiated  rights to internal
development  of  selected  products,  and  has  made  considerable  progress  in
evaluating their potential.  Organizational development is keeping pace with the
expanding opportunities.

         The final installment of Dr. Haseltine's  1,162,887 shares of founder's
stock vests during the first half of 1997. In view of Dr. Haseltine's importance
to the  Company's  accomplishments  thus  far and his  demonstrated  ability  to
provide the scientific and business leadership the Company needs for the future,
the Committee  decided to develop a stock option program for Dr. Haseltine which
would offer him the potential for  exceptional  equity growth,  as attractive as
those he has earned in the Company's  early years,  if the stock price increases
enough  to  reward  shareholders  even  more.  With  the  advice  of  a  leading
compensation consultant, the Committee estimated the option awards Dr. Haseltine
would  receive  over the next 5 years under a program  typical of the  Company's
peers,  assuming  continued top  performance,  and aggregated them into a single
grant on January 21, 1997, of options on 500,000 shares of Company common stock,
in lieu of anticipated annual grants during the coming 5 years. The terms are as
follows:

         150,000 shares                at market  price ($41 as of  January  21,
                                       1997) for 5 years, vesting at the rate of
                                       25% per year.
         150,000 shares                at $70 per share (71% over  market  price
                                       as of  January  21,  1997)  for 7  years,
                                       vesting at the rate of 20% per year.
         200,000 shares                at $100 per share (144% over market value
                                       as of  January  21,  1997)  for 10 years,
                                       vesting at the rate of 16 2/3% per year.

         DIRECTORS  COMPENSATION.  The  Committee  has awarded  stock options to
directors  in the past only at the time of initial  election  to the Board.  The
awards have typically been 11,250 shares, vesting at the rate of 2,250 share per
year. Reviewing past practices with our consultant, the Committee concluded that
the automatic  grant of options to purchase shares of the Company at the time of
initial  election or  appointment  as a director  and each year  thereafter,  is
needed to enhance the attractiveness of service on the Board.

         The Committee  believes the amendment to the 1994 Plan developed by our
consultant, described in Proposal 2, will serve shareholder interests by helping
to attract  top-cailber  directors and focusing their  attention on planning for
the Company's long-term success.

         COMPENSATION  DEDUCTION  LIMIT.  The  Committee has  considered  the $1
million  limit on  deductible  executive  compensation  that is not  performance
based,  and believes all executive  compensation  expenses will be deductible by
the Company for the foreseeable future.

PERFORMANCE GRAPH

         The  following  graph  compares  the  percentage  change  in the  total
cumulative  shareholder  return on the Company's  Common Stock since its initial
public stock offering  completed on December 2, 1993 with the  cumulative  total
return on the  Standard & Poor's  Composite  Index of 500 Stocks (the "S&P 500")
and the  capital  stocks of a peer  group (the  "Peer  Group") of  biotechnology
companies.* The comparison  assumes $100 was invested on December 2, 1993 in the
Company's  Common  Stock  and in  each  of the  foregoing  indices  and  assumes
reinvestment of dividends. The comparisons in this table are required by the SEC
and are not intended to forecast or be  necessarily  indicative of actual future
returns on the Company's Common Stock. In its 1994 Proxy Statement,  the Company
compared the total shareholder returns for the Company's Common Stock to the S&P
500 and the Nasdaq  Biotechnology  Index  ("NBI") for the 29 days  following the
Company's  initial public  offering on December 2, 1993. The Company did not use
the NBI for comparison to the performance of the Company's  Common Stock in 1994
because the NBI was not available for a portion of 1994.  Moreover,  the Company
believes that the Peer Group provides a better  comparison for stock performance
in 1994 and for the future  because the Peer Group is composed of companies more
representative of the Company's business.

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

         AGREEMENTS  WITH SMITHKLINE  BEECHAM.  In May 1993, the Company entered
into  the  SmithKline  Beecham   Collaboration   Agreements  pursuant  to  which
SmithKline   Beecham  was  granted  certain  exclusive  rights  to  develop  and
commercialize  therapeutic  and  diagnostic  products  within the "SB Field" (as
defined below) based on human genes  discovered by the Company.  Pursuant to the
SB  Collaboration  Agreements,  SmithKline  Beecham  has paid to the  Company an
aggregate of $125 million  including  $55.1  million  which was allocated to the
purchase of an aggregate of 1,351,738 shares of Common Stock.

         In  June  1996,  the SB  Collaboration  Agreements  were  substantially
amended  (the  "SB  Amendment").  The  SB  Amendment  allowed  the  Company  and
SmithKline  Beecham  together  to  enter  into  collaboration   agreements  with
additional  pharmaceutical  companies ("New  Collaboration  Partners") in the SB
Field (other than diagnostics and animal healthcare in which SmithKline  Beecham
has generally  retained  exclusive rights.) The "SB Field" is the field of human
and  animal  healthcare,   other  than  gene  therapy  (excluding  gene  therapy
vaccines),  antisense  products and the use of genes for synthesizing drugs that
were  known  at the time  the SB  Collaboration  Agreements  were  executed.  In
addition,  the SB  Amendment  provides  that each of the Company and  SmithKline
Beecham can  independently  designate  potential  therapeutic  proteins  for its
exclusive  development and  commercialization  (e.g.  marketing or outlicensing)
provided that it is the first among the Company,  SmithKline Beecham and the New
Collaboration  Partners to select the protein and certain research  requirements
are met  prior to such  designation.  In  addition,  the SB  Amendment  provides
procedures under which the Company and SmithKline  Beecham may independently (i)
research,  develop and commercialize antibody products directed against antigens
derived from the human genome database  created by the Company and (ii) identify
and use novel molecular  targets derived from the human genome database  created
by the Company to discover and develop small molecule  pharmaceutical  products,
provided that the Company will not initiate  screening of such targets for three
years  from the  effective  date of the SB  Amendment  and will not use  certain
targets  subject to  agreements  with third  parties,  subject to certain  other
restrictions.

         The SB Amendment  provides that SmithKline Beecham and the Company will
share  equally in any license fees and product  development  milestone  payments
paid under New  Collaboration  Partner  Agreements,  and that the  Company  will
receive all royalties and research support payments under such New Collaboration
Partner Agreements.  The SB Collaboration Agreements provide for payments to the
Company of royalties on net sales of products based on the Company's  patents or
technologies  within the SB Field ("SB Products") sold by SmithKline Beecham (or
its licensees) and milestone  payments in connection  with the development of SB
Products.  The  Company  has an  option  to co-  promote  SB  Products  sold  by
SmithKline Beecham, on a country-by-country basis, in the United States, Canada,
Mexico and Europe (subject to certain limitations as to rights granted to Takeda
and other parties). If the Company develops and markets or outlicenses a product
in the SB Field  pursuant to its rights  under the  agreements  with  SmithKline
Beecham,  SmithKline Beecham will generally be entitled to royalties or to share
in milestone  payments and license fees  received by the Company from  licensees
with respect to such  products.  The New  Collaboration  Partner  Agreement with
Schering Corporation and Schering-Plough,  Ltd. (collectively "Schering-Plough")
includes an option for Schering-Plough to co-develop and  co-commercialize up to
two products in the SB Field to which the Company has exclusive  development and
commercialization rights under the SB Collaboration Agreements. The SB

                                     - 29 -

<PAGE>



Collaboration  Agreements include an option for SmithKline Beecham to co-develop
and co-  commercialize  products  in the SB  Field  to  which  the  Company  has
exclusive  development and  commercialization  rights under the SB Collaboration
Agreements  and for  which  Schering-Plough  has not  exercised  its  option  to
co-develop  and  co-commercialize.  SmithKline  Beecham will also be entitled to
royalties on, and an option to co-promote  products outside the SB Field sold by
the Company which are based on or incorporate  patents or information  developed
by SmithKline Beecham based on the Human Genome Technology of the Company.

         The  initial  research  term  under  the  SB  Collaboration  Agreements
continues  through June 2001. After expiration of the initial research term, the
Company will have all rights to the Company's Human Gene Technology, except that
SmithKline  Beecham will retain  rights to the Company's  Human Gene  Technology
pursuant to research plans meeting certain specified criteria submitted prior to
expiration of the initial term,  Takeda will retain rights granted to it under a
license  agreement  prior to  expiration  of the initial  research  term and New
Collaboration   Partners   will  retain   rights   granted  to  them  under  New
Collaborations  Partner  Agreements.  SmithKline Beecham has the right to extend
the research term for up to five  additional  years by making certain  payments,
which would  extend the time for  submitting  research  plans as to  therapeutic
products other than antibody products and therapeutic protein products.

         The  Company  also  agreed to use its best  efforts  to elect a nominee
designated  by  SmithKline  Beecham as a  director  of the  Company.  SmithKline
Beecham has named  Robert A.  Armitage to be nominated by the Board of Directors
to stand for  election as  Director.  SmithKline  Beecham is also  entitled to a
right of first refusal to purchase new shares of Common Stock in any issuance of
equity  securities  by the Company,  other than  issuances  of certain  excluded
securities  (all as defined in the Stock Purchase  Agreement),  in amounts which
would not enable it to exceed its  percent  ownership  of the  Company as of the
execution date of the Collaboration  Agreement.  SmithKline  Beecham waived this
right of first refusal in connection with the Company's public offerings.  These
rights continue until the expiration of the initial research term (as defined in
the Stock  Purchase  Agreement) or termination  of the  Collaboration  Agreement
between the Company and SmithKline Beecham for certain reasons.

         In July 1995, the Company entered into a  collaboration  agreement with
MedImmune with respect to the development of drugs based upon infectious  agents
sequenced  by the Company or TIGR or as to which the Company  has  licensed  the
rights. The agreement provides that MedImmune will select, research, develop and
commercialize  product  candidates  from the Company's  information  and patents
relating to  bacteria.  The Company will be entitled to share in the net profits
from the sale of any products  covered by patent  claims of the Company or joint
patent rights and to share in license fees from products covered by such claims.
The agreement is terminable by either party for a certain period after notice of
termination is given and includes certain provisions restricting the Company and
MedImmune  from   collaborating   with  others  in  the  areas  covered  by  the
collaboration  agreement  during the term. In November 1996, the Company entered
into a  collaboration  agreement with OraVax Merieux Co. in which  MedImmune and
the  Company  granted  an  exclusive  license  for  use  of  the  Company's  and
MedImmune's  technology  for certain  vaccine  development.  Dr.  Cavanaugh is a
Director and beneficial owner of shares of common stock of MedImmune, Inc.

         The Company believes that all transactions  between the Company and its
officers, directors, principal stockholders or affiliates thereof, including the
transactions   with  TIGR,  in  light  of  all  of  the   circumstances  of  the
transactions,  have been,  and will in the future be, on terms no less favorable
to the Company than could be obtained from unaffiliated third parties.

                                  OTHER MATTERS

         The Company's executive officers, directors, and ten percent beneficial
owners of Common Stock are  required to file reports of ownership  and change of

the Meeting.  If any other business is properly presented at the Meeting,  it is
the  intention  of the  persons  named in the  accompanying  proxy  to vote,  or
otherwise act, in accordance with their judgment on such matters.

         Notwithstanding  anything  to  the  contrary  set  forth  in any of the
Company's  previous  filings under the  securities  laws that might  incorporate
future  filings,  the report of the  Compensation  Committee and the performance
graph included in this Proxy  Statement  shall not be  incorporated by reference
into any such filing.

employees,  without additional  remuneration,  may solicit proxies by telephone,
telegraph and personal interviews.  Brokers, custodians, and fiduciaries will be
requested  to forward  proxy  soliciting  material to the  beneficial  owners of
Common Stock held in their names,  and the Company will reimburse them for their
out-of-pocket  expenses  incurred in connection  with the  distribution of proxy
materials.

         "Terms of Directors.  The number of Directors of the Corporation  shall
be fixed by resolution duly adopted from time to time by the Board of Directors.
The Directors, shall be classified, with respect to the term for which they hold
office, into three classes,  as nearly equal in number as possible.  The initial
Class I  Director  shall  serve for a term  expiring  at the  annual  meeting of
stockholders  to be held in 2000, the initial Class II Directors shall serve for
a term expiring at the annual  meeting of  stockholders  to be held in 1999, and
the initial  Class III  Directors  shall serve for a term expiring at the annual
meeting  of  stockholders  to be  held  in  1998.  At  each  annual  meeting  of
stockholders,  the successor or successors of the class of Directors  whose term
expires at that  meeting  shall be elected by a  plurality  of the votes cast at
such meeting and shall hold office for a term expiring at the annual  meeting of
stockholders  held in the third year following the year of their  election.  The
Directors  elected to each class shall hold office  until their  successors  are
duly elected and qualified or until their earlier resignation or removal."

         The following  shall be added as the third paragraph under Article V of
the Certificate of Incorporation.

         "Vacancies.  Any and all vacancies in the Board of  Directors,  however
occurring,  including,  without limitation,  by reason of an increase in size of
the Board of Directors, or the death,  resignation,  disqualification or removal
of a Director,  shall be filled solely by the affirmative  vote of a majority of
the remaining  Directors then in office, even if less than a quorum of the Board
of Directors.  Any Director  appointed in accordance with the preceding sentence
shall hold office until the annual meeting of stockholders at which the class of
directors  for  which  he or she has been  chosen  is  elected  and  until  such
Director's  successor shall have been duly elected and qualified or until his or
her earlier resignation or removal. When the number of Directors is increased or
decreased,  the Board of Directors shall determine the class or classes to which
the increased or decreased  number of Directors  shall be  apportioned  so as to
maintain  each class as nearly equal in number as possible;  provided,  however,
that no  decrease  in the  number of  Directors  shall  shorten  the term of any
incumbent Director.

II.      OPTION TERMS AND CONDITIONS

2.1      AUTHORITY TO GRANT OPTIONS

         (a) The Committee shall, in its sole  discretion,  select the Employees
who receive  Options and  determine  the terms of such  Options,  including  the
number  of shares of  Common  Stock  subject  to an  Option,  the  schedule  for
exercisability  (including any requirements for satisfying  performance criteria
with respect to the Company  and/or the  Optionee),  the time and conditions for
expiration  of the  Option,  and the  form of  payment  due upon  exercise.  (In
determining  the type of payment that may be used, the Committee  shall consider
whether the acceptance of that form of payment will likely benefit the Company.)
The  Committee  may grant  more than one  Option to an  Employee,  provided  the
Employee is eligible under the terms of the Plan at the time of each  succeeding
grant. In its discretion, the Committee may condition the granting of Options

                                      - 5 -

<PAGE>



upon the Employee's  cancellation of all or part of a previously granted Option.
The Committee may set the Exercise  Price of the Options  without  regard to any
existing Options.

         (b) No more  than  500,000  shares of Common  Stock may be  subject  to
Options  granted to a single Employee under this Plan within a one calendar year
period.  If a portion of an Option is repriced,  the number of shares subject to
that portion shall be counted against the foregoing  individual limit.  Canceled
options shall be counted against the limit for the period during which they were
granted.

         (c) No Options shall be granted more than ten (10) years after the date
on which the Board adopts this Plan.

         (d)  Directors  of the  Company  who are not  employees  of the Company
("Eligible  Directors") will receive an option  ("Director  Option") to purchase
10,000  shares of Common Stock on the date that such person is first  elected or
appointed  a  director  ("Initial  Director  Option").  Commencing  on  the  day
immediately  following the date of the annual  meeting of  stockholders  for the
Company's  fiscal year ending  December 31, 1996,  each  Eligible  Director will
receive an automatic grant ("Automatic  Grant") of a Director Option to purchase
2,000 shares of Common Stock on the day  immediately  following the date of each
annual  meeting of  stockholders,  as long as such  director  is a member of the
Board of  Directors.  The exercise  price for each shares  subject to a Director
Option  shall be equal to the fair market  value of the Common Stock on the date
of grant. Initial Director Options shall become exercisable in five equal annual
installments  commencing  one  year  from the date the  option  is  granted  and

2.2      OPTION AGREEMENT

         The terms of each Option  shall be  contained  in an Option  Agreement,
signed by the Optionee,  that includes such terms and conditions consistent with
the  Plan  and  Rule  16b-3 as the  Committee  may in its  discretion  determine
necessary or advisable.

2.3      EXERCISE PRICE

         The Committee shall determine the Exercise Price under each Option, but
the  Exercise  Price may not be less than 100 percent  (100%) of the Fair Market
Value on the Date of  Grant.  If an Option  intended  to be an  Incentive  Stock
Option is granted to any Employee  who, at the Date of Grant,  owns Common Stock
possessing  more than 10 percent (10%) of the total combined voting power of all
classes of the Company's stock (or the stock of any  "subsidiary" or "parent" of
the Company as those terms are defined in Section 424 of the Code), the Exercise
Price shall be no less than 110 percent  (110%) of the Fair Market  Value on the
Date of Grant.

2.4      PERSON WHO MAY EXERCISE OPTIONS

         During the  lifetime  of the  Optionee,  only the  Optionee or his duly
appointed guardian or personal  representative  may exercise the Options.  After
his death, any exercisable portion of an Option may, before such portion becomes
unexercisable under the Plan or the applicable Option Agreement, be exercised by
the personal  representative of the Optionee or by any person empowered to do so
under the deceased  Optionee's will or under the then applicable laws of descent
and distribution.

2.5      EXERCISABILITY

         (a) Options granted  pursuant to this Plan shall be exercisable at such
times  and  under  such  conditions  as shall be  determined  by the  Committee;
provided, however, that no portion of

                                      - 7 -

<PAGE>



an Option shall be  exercisable  after the expiration of ten (10) years from its
Date of Grant and that no portion of an Incentive  Stock  Option  granted to any
Employee who, at the Date of Grant,  owns stock  possessing more than 10 percent
(10%) of the total combined  voting power for all classes of the Company's stock
(or the stock of any  "subsidiary" or "parent" of the Company as those terms are
defined in Section 424 of the Code) shall be exercisable after the expiration of
five (5) years from the Date of Grant.

         (b) Subject to the  provision of Section 3.7  (relating to  shareholder
approval),  Options shall become exercisable at such times and in such manner as
the Option  Agreement  may  provide;  provided,  however,  that by a  resolution
adopted after an Option  Agreement is entered into,  the Committee  may, on such
terms and conditions as it determines  appropriate,  and subject to Section 3.7,
accelerate the time at which the Optionee may exercise any portion of an Option.

         (c) No  portion  of an  Option  that  is  unexercisable  by  reason  of
Termination of Employment shall thereafter become exercisable, unless the Option
Agreement provides otherwise.

         (d) The  Company  will not  issue  fractional  shares  pursuant  to the
exercise of an Option,  but the  Committee  may, in its  discretion,  direct the
Company to make a cash payment instead of issuing fractional shares.

2.6      EXERCISE OF OPTIONS

         (a) An Optionee  shall  exercise any portion of an Option by delivering
the notice  described in Paragraph  (1) below to the Secretary of the Company or
his  office  on  or  before  the  date  such  portion  of  the  Option   becomes
unexercisable  under the  applicable  Option  Agreement  or the Plan and  making
payment as provided in Paragraph  (2) within three (3) business  days after such
delivery:


                                      - 8 -

<PAGE>



               (1) A written  notice of exercise,  in a form  complying with any
          rules the Committee may issue, that is signed by the Optionee and that
          specifies the number of shares of Common Stock  underlying the portion
          of the Option being exercised; and

               (2) Full payment by cashier's or certified  check of the Exercise
          Price for the shares of Common  Stock with respect to which the Option
          is being exercised.

         (b)  The   Optionee   shall  also   deliver  to  the   Committee   such
representations  and documents as the  Committee,  in its sole  discretion,  may
consider necessary or advisable in order to comply with applicable provisions of
the  Securities  Act of 1933 and any other Federal or state  securities or other
laws or regulations.  The Committee may, in its sole  discretion,  take whatever
additional  actions  it  deems  appropriate  to  so  comply  including,  without
limitation,  placing legends on certificates and issuing stop-transfer orders to
transfer agents and registrars.

         (c) If someone  other than the  Employee  exercises  any  portion of an
Option  pursuant to Section 2.4, the  Committee may request such proof as it may
consider  necessary or  appropriate  of the right of such person to exercise the
Option.

         (d) No adjustment  will be made for a dividend or other right for which
the record date  precedes  the Date of  Exercise,  except as provided in Section
3.1(a).

2.7  TAX WITHHOLDING

         The  Optionee  must  deliver to the Company the payment by cashier's or
certified  check to the Company of all amounts  that the Company  must  withhold
under Federal, state, or local law in connection with the exercise of the Option
if the  Company  cannot,  or decides  not to,  satisfy  withholding  obligations
through  additional  withholding  on  salary or wages.  Payment  of  withholding
obligations is due at the same time as is payment of the Exercise Price.

2.8      EXPIRATION OF OPTIONS

         (a) No one may  exercise  an Option  after the  expiration  of ten (10)
years from the Date of Grant or, if earlier and unless otherwise  provided in an
Option  Agreement for a  Nonqualified  Stock  Option,  the first to occur of the
following events:

               (1) Except in the case of any  Optionee  who is disabled  (within
          the meaning of Section  22(e)(3) of the Code), the expiration of three
          months from the date of the  Optionee's  Termination of Employment for
          any reason other than the  Optionee's  death unless the Optionee  dies
          within that three-month period;

               (2) In the  case  of an  Optionee  who is  disabled  (within  the
          meaning of Section  22(e)(3) of the Code),  the expiration of one year
          from the date of the  Optionee's  Termination  of  Employment  for any
          reason  other than such  Optionee's  death  unless the  Optionee  dies
          within that one-year period; or

               (3) The  expiration  of one year from the date of the  Optionee's
          death.

         (b) Subject to the  provisions  of Section  2.8(a),  the  Committee may
provide in the terms of an Option  Agreement  that any  portion  of the  Option,
whether then  exercisable  or not,  expires  immediately  upon a Termination  of
Employment  or that any portion of the Option  shall become  exercisable  in the
event of a  Termination  of  Employment  because of the  Optionee's  retirement,
death, or disability.

2.9      TRANSFER RESTRICTIONS

         Unless otherwise approved in writing by the Committee, no one may sell,
assign, pledge, encumber, or otherwise transfer shares acquired upon exercise of
any Option until at least six months have elapsed from (but  excluding) the Date
of Grant. (Solely for purposes of this

                                     - 10 -

<PAGE>



Section,  the  Date of Grant  occurs  upon  the  later of the Date of Grant  (as
defined  in  Section  1.2(g))  or the date as of which the  shareholders  of the
Company  approve  the Plan  pursuant  to  Section  3.7.) The  Committee,  in its
absolute  discretion,  may impose such other restrictions on the transferability
of  the  shares  purchasable  upon  the  exercise  of  an  Option  as  it  deems
appropriate.  The Option  Agreement shall set forth any such other  restriction,
and the certificates evidencing such shares may refer to such restrictions.

2.10     $100,000 LIMIT FOR INCENTIVE STOCK OPTIONS

         No portion of an Option  granted to an Optionee  shall be treated as an
Incentive  Stock  Option to the extent such portion of an Option would cause the
aggregate Fair Market Value of all shares with respect to which  Incentive Stock
Options are  exercisable by such Optionee for the first time during any calendar
year to exceed $100,000.  For purposes of determining whether an Incentive Stock
Option  would  cause such  aggregate  Fair Market  Value to exceed the  $100,000
limitation,  all such Incentive Stock Options shall be taken into account in the
order  granted and the Fair Market Value for each share under an option shall be
determined  as of that  option's  date of grant.  For purposes of this  section,
Incentive  Stock Options  include all incentive stock options under all plans of
the  Company  that are  "incentive  stock  option  plans"  within the meaning of
Section 422 of the Code.

2.11     NO EXERCISE OF OUT-OF-THE-MONEY OPTIONS

         An  Optionee  may not  exercise  any  portion  of an Option  while that
portion of the Option is out-of-the-money,  i.e., while the exercise price for a
share of Common Stock  underlying  that  portion of the Option  exceeds the Fair
Market Value of a share of Common Stock.

III.  OTHER PROVISIONS

3.1      ADJUSTMENT PROVISIONS

         (a)  Subject to any  required  action by the  Company  (which  shall be
promptly  taken) or its  shareholders,  and  subject  to the  provisions  of the
Delaware General  Corporation Law, if the outstanding Common Stock are increased
or  decreased or changed  into or  exchanged  for a different  number or kind of
security  by  reason of any  recapitalization,  reclassification,  stock  split,
reverse stock split,  combination of shares, exchange of shares, stock dividend,
or other distribution payable in capital stock, or other increase or decrease in
such Common Stock is effected  without receipt of  consideration  by the Company
occurring after the Date of Grant of an Option, a proportionate  and appropriate
adjustment  shall be made in the number of shares of Common Stock underlying the
Option, so that the proportionate interest of the Optionee immediately following
such event shall, to the extent  practicable,  be the same as immediately before
such event. A commensurate change will be made in the maximum number and kind of
shares  provided in Section 1.3(a) and 2.1(b).  Any such adjustment in an Option
shall not  change  the  total  price  with  respect  to  shares of Common  Stock
underlying  the   unexercised   portion  of  the  Option  but  shall  include  a
corresponding proportionate adjustment in the Option's Exercise Price.

         (b) In addition to the adjustments  covered under Section 3.1(a) above,
any Option grant may contain  provisions to the effect that upon the  occurrence
of certain  events,  including a change in control of the Company (as defined by
the Committee in the Optionee's Option Agreement),  any outstanding  Options not
theretofore  exercisable  or free from  restrictions,  as the case may be, shall
either immediately, or upon a further determination made by the Committee at the
time of the event, become fully exercisable or free from restrictions.

         (c) The  Committee  will  make  adjustments  and  determinations  under
Sections 3.1(a) and 3.1(b),  and its determination will be final,  binding,  and
conclusive.


                                     - 12 -

<PAGE>



         (d) Upon the  dissolution  or  liquidation  of the  Company,  or upon a
reorganization, merger, or consolidation of the Company as a result of which the
outstanding  securities of the class of  securities  then subject to the Options
are changed  into or  exchanged  for cash or property or  securities  not of the
Company's issue, or any combination thereof, or upon a sale of substantially all
the  property of the Company to, or the  acquisition  of shares of Common  Stock
representing more than eighty percent (80%) of the voting power of the shares of
Common Stock then  outstanding  by, another  corporation or person,  the Options
shall  terminate,  unless  provision be made in writing in connection  with such
transaction for the assumption of Options theretofore granted under the Plan, or
the  substitution  for  such  options  of any  options  covering  the  stock  or
securities  of a  successor  employer  corporation,  or a parent  or  subsidiary
thereof,  with  appropriate  adjustments  as to the number and kind of shares of
stock and prices,  in which event the Options  shall  continue in the manner and
under the terms so provided.  If an Option would otherwise terminate pursuant to
the foregoing  sentence,  the Optionee shall have the right, at such time before
the  consummation  of the  transaction  causing such  termination as the Company
shall reasonably designate,  to exercise the unexercised portions of the Option,
including the portions thereof that would,  but for this subsection,  not yet be
exercisable.

3.2      CONTINUATION OF EMPLOYMENT OR SERVICE

         Nothing in the Plan or in any instrument  executed pursuant to the Plan
will confer upon any  Optionee any right to continue in the employ or service of
the Company or affect the right of the Company to terminate  the  employment  or
service  of any  Optionee  at any time with or  without  cause,  subject  to any
contrary terms in a written  employment  agreement or contract for services with
the Optionee.

3.3      COMPLIANCE WITH GOVERNMENT REGULATIONS

         No shares of Common  Stock will be issued  pursuant to an Option  until
all applicable  requirements  imposed by Federal and state  securities and other
laws, rules, and regulations, and

                                     - 13 -

<PAGE>



by any regulatory agencies having jurisdiction,  and by any stock exchanges upon
which the  Common  Stock  may be listed  have been  fully  met.  As a  condition
precedent to the issuance of shares of Common Stock  pursuant to an Option,  the
Company may require the  Optionee to take any  reasonable  action to comply with
such requirements.

3.4      PRIVILEGES OF STOCK OWNERSHIP

         No  Optionee  and no  beneficiary  or other  person  claiming  under or
through  such  Optionee  will have any right,  title,  or  interest in or to any
shares of Common Stock  allocated  or reserved  under the Plan or subject to any
Option except as to such shares of Common  Stock,  if any, that have been issued
to such Optionee.

3.5      NONTRANSFERABILITY OF OPTIONS AND COMMON STOCK

         Unless  otherwise  approved in writing by the Committee,  an Option may
not be assigned, transferred,  pledged, hypothecated, or disposed of in any way,
whether by  operation  of law or  otherwise  or through  any legal or  equitable
proceedings  (including  bankruptcy),  to any person by the Optionee,  except by
will or by  operation of  applicable  laws of descent and  distribution.  Unless
otherwise approved in advance in writing by the Committee,  the Optionee may not
sell,  assign,  pledge,  encumber,  or otherwise transfer shares of Common Stock
acquired  upon  exercise of an Option until at least six (6) months have elapsed
from (but excluding) the Date of Grant.  The Committee,  in its sole discretion,
may impose such other  restrictions  on the  transferability  of Options,  as it
deems  appropriate.  The  Option  Agreement  shall  set  forth  any  such  other
restrictions,  and the  certificates  evidencing such shares of Common Stock may
refer to such restrictions.

3.6      AMENDMENT AND TERMINATION OF PLAN; AMENDMENT OF OPTION


         (a) The Board will have the power,  in its sole  discretion,  to amend,
suspend, or terminate the Plan at any time;  provided,  however,  that the Board
may not amend the Plan without  approval of the  shareholders  of the Company if
Rule 16b-3 requires such approval. The Board is specifically authorized to adopt
any  amendment  to this Plan deemed by the Board to be necessary or advisable to
ensure that the Incentive Stock Options or Nonqualified  Stock Options available
under  the  Plan  continue  to be  treated  as  such,  respectively,  under  all
applicable laws.

         (b) Except as otherwise  provided by the applicable Option Agreement or
by Section 1.4, 3.1, or 3.8, the  Committee  may not,  without the consent of an
Optionee,  make  modifications  in the terms and  conditions  of an Option  that
adversely  affect the  Optionee.  No  Incentive  Stock  Option may be  modified,
extended,  or renewed,  without the consent of an Optionee, if such action would
cause it to cease to be an incentive  stock option within the meaning of Section
422 of the Code.

         (c) No amendment,  suspension, or termination of the Plan will, without
the consent of the Optionee,  alter, terminate,  impair, or adversely affect any
right or obligations under any Option previously granted under the Plan.

3.7      APPROVAL OF PLAN BY STOCKHOLDERS

         The Company  will submit  this Plan for the  approval of the  Company's
shareholders.  The Committee may grant Options before such shareholder approval,
but the Optionee cannot  exercise  Options before the  shareholders  approve the
Plan.  Moreover,  if the  shareholders  do not approve the Plan within 12 months
after the Board's initial adoption of the Plan, all Options  previously  granted
under the Plan shall  thereupon be canceled and become void.  The Company  shall
take  such  actions  regarding  the  Plan as may be  necessary  to  satisfy  the
requirements of Rule 16b-3(b).

3.8      CONFORMITY TO SECURITIES LAW

         The Plan is  intended  to  conform  to the  extent  necessary  with all
provisions  of the  Securities  Act  of  1933  and  the  Exchange  Act  and  all
regulations  and rules  promulgated by the  Securities  and Exchange  Commission
thereunder,  including without limitation Rule 16b-3.  Notwithstanding  anything
herein to the contrary,  the Committee  shall  administer  the Plan, and Options
shall be granted  and may be  exercised,  only in such a manner as to conform to
such laws,  rules, and  regulations.  To the extent permitted by applicable law,
the Plan and Options  granted  hereunder  shall be deemed  amended to the extent
necessary to conform to such laws,  rules,  and  regulations.  To the extent any
provision of the Plan or action by the Committee fails to comply with Rule 16b-3
(as in effect with  respect to the Plan on the date such  action is taken),  the
provision  or action shall be deemed null and void,  to the extent  permitted by
law and deemed advisable by the Committee.

3.9      APPLICABLE LAW

         This Plan shall be governed by and  construed  in  accordance  with the
laws of the State of Delaware.

IV.      DURATION OF PLAN

         Unless sooner terminated by the Board, the Plan will terminate on March
14, 2004.
