                                  PROPOSAL ONE
                              ELECTION OF DIRECTORS

Nominees

     The Company's Restated  Certificate of Incorporation and Bylaws provide for
a Board of Directors that is divided into three classes.  The directors in Class
I hold office until the 2000 Annual  Meeting of  Stockholders,  the directors in
Class II hold office  until the 2001  Annual  Meeting of  Stockholders,  and the
directors of Class III hold office until the 1999 Annual Meeting of Stockholders
(or, in each case,  until their  successors  are duly  elected and  qualified or
their earlier  resignation,  removal from office or death), and, after each such
election, the directors in each such case will then serve in succeeding terms of
three years and until their successors are duly elected and qualified.

     The Company currently has seven directors, with three directors in Class I,
two  directors in Class II, and two  directors in Class III. The terms of office
of the Class I directors,  Daniel L. Kisner, M.D., David Schnell,  M.D. and Mark
B.  Skaletsky  expire at the 2000 Annual Meeting of  Stockholders.  The terms of
office of Class II  directors,  Hugh Y.  Rienhoff,  Jr., M.D. and John P. Walker
expire at the Company's 2001 Annual Meeting of Stockholders. The terms of office
of the Class III directors James E. Rurka and Keith A. Bostian,  Ph.D. expire at
the 1999 Annual  Meeting of  Stockholders.  Effective  April 13, 1998,  L. James
Strand,  M.D. and Joseph S. Lacob  resigned from the Board of  Directors.  These
vacancies were filled with the  appointment  of Mr.  Skaletsky and Dr. Kisner as
Class I directors effective April 14, 1998 and April 24, 1998, respectively.

     Two Class III  directors  are to be elected at the 1999  Annual  Meeting of
Stockholders.  Unless  otherwise  instructed,  the proxy  holders  will vote the
proxies  received by them for the Company's  nominees named below.  In the event
that any  nominee of the Company is unable or declines to serve as a director at
the time of the Annual  Meeting of  Stockholders,  the proxies will be voted for
any nominee who shall be  designated  by the present  Board of Directors to fill
the vacancy.  It is not expected that any nominee will be unable or will decline
to serve as a director.  In the event that additional  persons are nominated for
election as directors,  the proxy holders intend to vote all proxies received by
them in such a manner as will  assure the  election  of as many of the  nominees
listed  below as possible,  and in such event the specific  nominees to be voted
for will be determined by the proxy holders.

     The nominees,  and certain  information about them as of December 31, 1998,
are set forth below:

Board Meetings and Committees

     The Board of Directors held six meetings and took action by written consent
three times during fiscal 1998. No incumbent director attended fewer than 75% of
the  aggregate of the total number of meetings of the Board of Directors and the
total  number of meetings  held by all  committees  of the Board of Directors on
which he served during fiscal 1998.

     The Board of  Directors  has four  standing  committees:  the  Compensation
Committee,  the Audit  Committee,  the Option Grant Committee and the Nominating
Committee.

     During 1998, directors David Schnell,  M.D., L. James Strand, M.D. and John
P.  Walker  served on the  Compensation  Committee,  which sets  guidelines  for
hiring,  salaries and incentive  compensation for employees of the Company other
than executive  officers,  and makes  recommendations  to the Board of Directors
with regard to salaries and incentive compensation for executive officers of the
Company.  Mr.  Rurka,  President  and Chief  Executive  Officer of the  Company,
participates  in all discussions and decisions  regarding  hiring,  salaries and
incentive compensation for all employees and consultants of the Company,  except
that Mr.  Rurka is  excluded  from  discussions  regarding  his own  salary  and
incentive  compensation.  The Compensation  Committee held three meetings during
fiscal 1998.  Each  committee  member  attended  the  meetings  held during such
member's tenure on the committee.

     During  1998,  directors  Joseph S. Lacob,  Mark B.  Skaletsky  and Hugh Y.
Rienhoff, Jr., M.D. served on the Audit Committee, which reviews the results and
scope of the audit and other  services  provided  by the  Company's  independent
auditors.  The Audit  Committee  held two  meetings  during  fiscal  1998.  Each
committee  member  attended the meetings held during such member's tenure on the
committee except Mr. Skaletsky,  who joined the Board of Directors and the Audit
Committee during fiscal 1998 but did not attend the one Audit Committee  meeting
held during his tenure.

     During 1998,  director James E. Rurka served on the Option Grant  Committee
which  was  established  principally  to  grant  stock  options  to  non-officer
employees upon  commencement  of employment  with the Company in accordance with
the  guidelines  established  by the  Compensation  Committee.  During 1998, the
Option Grant Committee did not meet but did take action by written consent.

     During 1998,  directors  James E. Rurka,  David  Schnell,  M.D. and John P.
Walker served on the Nominating Committee which interviews, evaluates, nominates
and recommends  individuals  for membership on the Company's  Board of Directors
and  committees  thereof and  nominates  specific  individuals  to be elected as
officers of the  Company by the Board of  Directors.  During  fiscal  1998,  the
Nominating  Committee held one meeting.  The Nominating  Committee will consider
nominees for directors  nominated by stockholders  upon submission in writing to
the Secretary of the Company of the names of such  nominees in  accordance  with
the Company's Bylaws.

Compensation of Directors

     Non-employee  directors of the Company are entitled to  participate  in the
Company's 1996 Director  Option Plan. Each individual who becomes a non-employee
director for the first time will  automatically be granted an option to purchase
16,000 shares of Common Stock on the date of his or her election or  appointment
to the Board of Directors, provided such individual was not immediately prior to
such time employed by the Company. Such options are exercisable at a price equal
to the fair market value of the Company's Common Stock on the date the option is
granted, and the right to exercise the shares subject to the option vests over a
four-year  period.  Thereafter,  at  each  annual  stockholders'  meeting,  each
non-employee  director  with at least  six  months  of  service  on the Board of
Directors  will  automatically  be granted an option to purchase 4,000 shares of
Common  Stock  (8,000  shares for the  Chairman of the Board).  Such options are
exercisable  at a price equal to the fair market value of the  Company's  Common
Stock on the date the option is granted,  and the right to  exercise  the shares
subject to the  option  vests over a one-year  period.  The  Company  granted an
option to purchase an additional 16,000 shares of Common Stock to John P. Walker
when he was named Chairman of the Board in February 1999.

     The Company  previously  paid each  non-employee  director  $1,000 for each
Board of Directors'  meeting which such director attended in person and $500 for
each committee  meeting which such committee  member attended in person.  In the
fourth quarter of fiscal 1998, the Company  replaced this method of compensation
with a new  method  under  which  non-employee  


                                       4

<PAGE>

directors receive a flat fee of $10,000 per annum,  payable  quarterly  ($15,000
for the Chairman of the Board).  Directors otherwise have received no other fees
for  services   provided  in  that  capacity  but  have  been   reimbursed   for
out-of-pocket  expenses in  connection  with  attendance  at Board of Directors'
meetings.  Directors  receive no compensation for meetings attended by telephone
or for actions taken by written consent.

Vote Required

     The two nominees  receiving the highest number of affirmative  votes of the
shares  present or  represented by proxy and entitled to vote will be elected as
directors.  Votes  withheld  from any  director  are  counted  for  purposes  of
determining the presence or absence of a quorum,  but have no legal effect under
Delaware law.  While there is no  definitive  statutory or case law authority in
Delaware as to the proper  treatment of abstentions and broker  non-votes in the
election of directors,  the Company  believes that both  abstentions  and broker
non-votes  should be counted for  purposes of whether a quorum is present at the
Annual Meeting. In the absence of precedent to the contrary, the Company intends
to treat  abstentions  and broker  non- votes with  respect to the  election  of
directors in this manner.

             THE BOARD OF DIRECTORS RECOMMENDS THAT THE STOCKHOLDERS
                    VOTE "FOR" THE ELECTION OF THE NOMINEES.

                                  PROPOSAL TWO
                 AMENDMENT OF 1993 AMENDED INCENTIVE STOCK PLAN


     In April 1993, the Company's  Board of Directors (the "Board")  adopted the
1993 Amended Incentive Stock Plan (the "Stock Plan"),  which was approved by the
stockholders  in April 1994.  Options granted under the Stock Plan may be either
"incentive   stock  options,"  as  defined  in  Section  422  of  the  Code,  or
nonstatutory  stock options.  See "Certain Federal Income Tax Information" below
for information concerning the tax treatment of both incentive stock options and
nonstatutory  stock  options.  The Board of Directors  and  stockholders  of the
Company have previously  reserved for issuance  2,280,000 shares of Common Stock
under  the  Stock  Plan.  In April  1999,  the Board of  Directors  approved  an
amendment to the Stock Plan,  subject to stockholder  approval,  to increase the
shares  reserved  for  issuance  thereunder  by  300,000  shares  to a total  of
2,580,000  shares.  As of March 31, 1999,  options to purchase  1,517,205 shares
were outstanding  under the Stock Plan, a total of approximately  508,284 shares
had been issued upon the  exercise of options  granted  under the Stock Plan and
approximately 254,511 shares remained available for future grant.

     At the Annual Meeting, the stockholders are being requested to consider and
approve  the  proposed  amendment  to the Stock Plan to  increase  the number of
shares of Common  Stock  reserved  for issuance  thereunder  by 300,000  shares,
bringing the total number of shares  issuable  under the Stock Plan to 2,580,000
shares.

Summary of the Stock Plan

     General.  The  purpose of the Stock Plan is to attract  and retain the best
available  personnel  for  positions  of  substantial  responsibility  with  the
Company, to provide additional incentive to the employees and consultants of the
Company and to promote the success of the Company's  business.  Options  granted
under the Stock  Plan may be either  "incentive  stock  options,"  as defined in
Section 422 of the Internal  Revenue Code of 1986, as amended (the  "Code"),  or
nonstatutory stock options.

     Administration.  The Stock Plan may generally be  administered by the Board
or a Committee appointed by the Board (as applicable, the "Administrator").  The
Administrator may make any determinations  deemed necessary or advisable for the
Stock Plan.

     Eligibility. Nonstatutory stock options may be granted under the Stock Plan
to employees and  consultants of the Company and any parent or subsidiary of the
Company.  Incentive  stock  options  may  be  granted  only  to  employees.  The
Administrator,  in its discretion, selects the employees and consultants to whom
options  may be  granted,  the  time or times at  which  such  options  shall be
granted, and the exercise price and number of shares subject to each such grant.

     Limitations.  Section 162(m) of the Code places limits on the deductibility
for  federal  income tax  purposes  of  compensation  paid to certain  executive
officers of the Company.  In order to preserve the  Company's  ability to deduct
the  compensation  income  associated with options granted to such persons,  the
Stock Plan provides  that no employee may be granted,  in any fiscal year of the
Company,  options  to  purchase  more  than  500,000  shares  of  Common  Stock.
Notwithstanding  this  limit,  however,  in  connection  with such  individual's
initial  employment  with  the  Company,  he or she may be  granted  options  to
purchase up to an additional 500,000 shares of Common Stock.

     Terms and Conditions of Options. Each option is evidenced by a stock option
agreement between the Company and the optionee,  and is subject to the following
terms and conditions:

     (a) Exercise  Price.  The  Administrator  determines  the exercise price of
options at the time the options are granted.  The exercise price of an incentive
stock  option may not be less than 100% of the fair  market  value of the Common
Stock on the date such option is granted; provided,  however, the exercise price
of an incentive  stock option granted to a 10%  stockholder may not be less than
110% of the fair  market  value of the Common  Stock on the date such  option is
granted.  The fair market value of the Common Stock is generally determined with
reference  to the closing sale price for the Common Stock (or the closing bid if
no sales were  reported)  on the last  market  trading day prior to the date the
option is granted.

     (b) Exercise of Option; Form of Consideration. The Administrator determines
when options  become  exercisable,  and may in its  discretion,  accelerate  the
vesting of any outstanding option. The means of payment for shares issued upon


                                       6
<PAGE>


exercise  of an option is  specified  in each option  agreement.  The Stock Plan
permits  payment to be made by cash,  check,  promissory  note,  other shares of
Common Stock of the Company (with some restrictions), cashless exercises, or any
combination thereof.

     (c) Term of Option.  The term of an  incentive  stock option may be no more
than ten (10)  years  from the date of  grant;  provided  that in the case of an
incentive stock option granted to a 10% stockholder,  the term of the option may
be no more  than  five (5)  years  from  the date of  grant.  No  option  may be
exercised after the expiration of its term.

     (d)  Termination of Employment.  If an optionee's  employment or consulting
relationship terminates for any reason (including death or disability), then all
options held by the  optionee  under the Stock Plan expire on the earlier of (i)
the date set forth in his or her notice of grant or (ii) the expiration  date of
such option.  The Stock Plan and the option  agreement  may provide for a longer
period of time for the  option to be  exercised  after the  optionee's  death or
disability than for other terminations.  To the extent the option is exercisable
at the time of such  termination,  the optionee (or the optionee's estate or the
person who acquires the right to exercise the option by bequest or  inheritance)
may exercise all or part of his or her option at any time before termination.

     (e)  Nontransferability  of Options.  Unless  otherwise  determined  by the
Administrator,  options granted under the Stock Plan are not transferable  other
than by will or the  laws of  descent  and  distribution,  and may be  exercised
during the optionee's lifetime only by the optionee.

     (f) Other  Provisions.  The stock option agreement may contain other terms,
provisions  and  conditions  not  inconsistent  with  the  Stock  Plan as may be
determined by the Administrator.

     Adjustments Upon Changes in Capitalization.  In the event that the stock of
the Company  changes by reason of any stock split,  reverse  stock split,  stock
dividend,  combination,  reclassification or other similar change in the capital
structure  of  the  Company  effected  without  the  receipt  of  consideration,
appropriate adjustments shall be made in the number and class of shares of stock
subject to the Stock  Plan,  the number and class of shares of stock  subject to
any option  outstanding under the Stock Plan, and the exercise price of any such
outstanding option.

     In the event of a liquidation or dissolution,  any unexercised options will
terminate.  The  Administrator  may, in its sole  discretion,  provide that each
optionee  shall  have  the  right to  exercise  all of the  optionee's  options,
including those not otherwise exercisable.

     In connection with any merger, consolidation, acquisition of assets or like
occurrence involving the Company, each outstanding option shall be assumed or an
equivalent  option  substituted by the successor  corporation.  If the successor
corporation  refuses  to  assume  the  options  or to  substitute  substantially
equivalent  options,  the  Administrator  shall have the discretion to allow the
optionee to exercise the option as to all the optioned stock,  including  shares
not otherwise  exercisable.  In such event, the  Administrator  shall notify the
optionee  that the option is fully  exercisable  for fifteen  (15) days from the
date of such  notice  and that the option  terminates  upon  expiration  of such
period.

     Amendment and  Termination of the Stock Plan.  The Board may amend,  alter,
suspend or terminate the Stock Plan,  or any part  thereof,  at any time and for
any reason.  However,  the Company  shall  obtain  stockholder  approval for any
amendment to the Stock Plan to the extent necessary and desirable to comply with
applicable law. No such action by the Board or stockholders  may alter or impair
any option  previously  granted under the Stock Plan without the written consent
of the optionee.  Unless terminated earlier,  the Stock Plan shall terminate ten
years  from the date of its  approval  by the  stockholders  or the Board of the
Company, whichever is earlier.

Federal Income Tax Consequences

     Incentive  Stock  Options.  An optionee who is granted an  incentive  stock
option does not  recognize  taxable  income at the time the option is granted or
upon its exercise,  although the exercise is an adjustment  item for alternative
minimum tax  purposes and may subject the  optionee to the  alternative  minimum
tax.  Upon a  disposition  of the shares  more than two years after grant of the
option and one year after exercise of the option, any gain or loss is treated as
long-term  capital gain or loss.  Net capital  gains on shares held more than 12
months may be taxed at a maximum federal rate of 20%. Capital losses are allowed
in full against  capital gains and up to $3,000  against other income.  If these
holding periods are not satisfied, the



                                       7
<PAGE>


optionee  recognizes  ordinary  income at the time of  disposition  equal to the
difference between the exercise price and the lower of (i) the fair market value
of the shares at the date of the option  exercise  or (ii) the sale price of the
shares.  Any gain or loss  recognized  on such a  premature  disposition  of the
shares in  excess of the  amount  treated  as  ordinary  income  is  treated  as
long-term or short-term capital gain or loss, depending on the holding period. A
different rule for measuring  ordinary income upon such a premature  disposition
may apply if the optionee is also an officer,  director,  or 10%  stockholder of
the  Company.  Unless  limited by  Section  162(m) of the Code,  the  Company is
entitled to a deduction in the same amount as the ordinary income  recognized by
the optionee.

     Nonstatutory  Stock  Options.  An optionee  does not  recognize any taxable
income  at the time he or she is  granted  a  nonstatutory  stock  option.  Upon
exercise,  the optionee  recognizes  taxable  income  generally  measured by the
excess of the then fair market value of the shares over the exercise price.  Any
taxable income  recognized in connection  with an option exercise by an employee
of the Company is subject to tax  withholding by the Company.  Unless limited by
Section  162(m) of the Code,  the Company is entitled to a deduction in the same
amount as the ordinary income recognized by the optionee.  Upon a disposition of
such  shares by the  optionee,  any  difference  between  the sale price and the
optionee's  exercise  price,  to the extent not  recognized as taxable income as
provided  above,  is treated as  long-term or  short-term  capital gain or loss,
depending on the holding  period.  Net capital gains on shares held more than 12
months may be taxed at a maximum federal rate of 20%. Capital losses are allowed
in full against capital gains and up to $3,000 against other income.

     The  foregoing is only a summary of the effect of federal  income  taxation
upon optionees and the Company with respect to the grant and exercise of options
under the Stock Plan.  It does not purport to be complete,  and does not discuss
the tax  consequences of the employee's or consultant's  death or the provisions
of the income tax laws of any  municipality,  state or foreign  country in which
the employee or consultant may reside.

Vote Required

     The  affirmative  vote of the holders of a majority  of the shares  casting
their votes at the Annual  Meeting will be required to approve the  amendment of
the 1993 Amended Incentive Stock Plan.

          THE BOARD OF DIRECTORS RECOMMENDS VOTING "FOR" THE AMENDMENT
                    OF THE 1993 AMENDED INCENTIVE STOCK PLAN.



                                       8
<PAGE>


                                 PROPOSAL THREE
                     AMENDMENT OF 1996 DIRECTOR OPTION PLAN


     The  Company's  Board of  Directors  (the  "Board") and  stockholders  have
previously  adopted and approved the Company's  1996  Director  Option Plan (the
"Director Plan"). The Board and stockholders of the Company previously  reserved
80,000 shares of Common Stock under the Director  Plan. In April 1999, the Board
of Directors  approved an amendment to the Director Plan, subject to stockholder
approval,  to increase the shares  reserved for  issuance  thereunder  by 70,000
shares,  bringing the total number of shares issuable under the Director Plan to
150,000.  As of March 31, 1999,  8,000 shares were available for future issuance
under the Director Plan.

     At the Annual Meeting, the stockholders are being requested to consider and
approve the proposed  amendment  to the Director  Plan to increase the number of
shares of Common  Stock  reserved  for  issuance  thereunder  by 70,000  shares,
bringing the total number of shares issuable under the Director Plan to 150,000.

Summary of the Director Plan

     General. The purpose of the Director Plan is to attract and retain the best
available  personnel  for service as outside  directors,  to provide  additional
incentive to the outside  directors and to encourage their continued  service on
the Board.  Options  granted under the Director Plan may be  nonstatutory  stock
options.

     Administration.  The Director  Plan may  generally be  administered  by the
Board (the  "Administrator"),  although  grants made under the Director Plan are
automatic and non-discretionary.

     Eligibility. Options may be granted under the Director Plan only to outside
directors.

     Terms and Conditions of Options. Each option is evidenced by a stock option
agreement between the Company and the optionee,  and is subject to the following
terms and conditions:

     (a) Option Grants. All grants of options to outside directors are automatic
and  nondiscretionary.  Each  outside  director  is  granted  a first  option to
purchase  16,000 shares of the Common Stock of the Company (the "First  Option")
on the date on which he or she first becomes an outside director. On the date of
each  annual  meeting of the  stockholders  each  outside  director is granted a
subsequent  option to purchase  4,000  shares of the Common Stock of the Company
(the "Subsequent  Option"),  provided that on such date the outside director has
served on the Board for at least six (6) months.

     (b) Exercise Price. The exercise price per share is 100% of the fair market
value of the Common  Stock on the date such option is  granted.  The fair market
value of the Common Stock is generally  determined with reference to the closing
sale price for the Common  Stock (or the closing bid if no sales were  reported)
on the last market trading day prior to the date the option is granted.

     (c) Exercise of Option;  Form of  Consideration.  The First Option  becomes
exercisable as to one-eighth (1/8th) of the shares subject to the option six (6)
months  after  the  date of  grant,  and as to an  additional  one  forty-eighth
(1/48th) of the shares subject to the option each month thereafter, provided the
outside director  continues to serve as a director on such dates. The Subsequent
Option becomes  exercisable as to one twelfth  (1/12th) of the shares subject to
the option each month  after the date of grant,  provided  the outside  director
continues to serve as a director on such dates.  The means of payment for shares
issued upon  exercise of an option is  specified in each option  agreement.  The
Director Plan permits payment to be made by cash, check,  other shares of Common
Stock of the  Company  (with  some  restrictions),  cashless  exercises,  or any
combination thereof.

     (d) Term of Option. The term of an option may be no more than 10 years from
the date of grant. No option may be exercised after the expiration of its term.

     (e) Termination of Director Status.  If an optionee's  status as a director
terminates  for any reason (other than death or  disability),  then the optionee
may exercise the option,  but only within three (3) months following the date of
such  termination,  and only to the extent  that the  optionee  was  entitled to
exercise the option on the date of such termination. The



                                       9
<PAGE>



Director  Plan and the option  agreement may provide for a longer period of time
for the option to be exercised after the optionee's death or disability than for
other terminations.  To the extent the option is exercisable at the time of such
termination,  the optionee (or the optionee's  estate or the person who acquires
the right to exercise the option by bequest or inheritance)  may exercise all or
part of his or her option at any time before termination.

     Nontransferability of Options.  Options granted under the Director Plan are
not transferable other than by will or the laws of descent and distribution, and
may be exercised during the optionee's lifetime only by the optionee.

     Adjustments Upon Changes in Capitalization.  In the event that the stock of
the Company  changes by reason of any stock split,  reverse  stock split,  stock
dividend,  combination,  reclassification or other similar change in the capital
structure  of  the  Company  effected  without  the  receipt  of  consideration,
appropriate adjustments shall be made in the number and class of shares of stock
subject to the Director Plan, the number and class of shares of stock subject to
any option  outstanding  under the Director  Plan, and the exercise price of any
such  outstanding  option.  In the event of a liquidation  or  dissolution,  any
unexercised options will terminate.

     In connection  with any merger,  acquisition  of assets or like  occurrence
involving the Company, each outstanding option shall be assumed or an equivalent
option substituted by the successor  corporation.  If the successor  corporation
refuses to assume the options or to substitute  substantially equivalent options
the options shall  terminate as of the date of such merger.  In such event,  the
Board shall notify the optionee that the option is fully exercisable for fifteen
(15) days  from the date of such  notice  and that the  option  terminates  upon
expiration of such period.

     Amendment and Termination of the Director Plan. The Board may amend, alter,
suspend or terminate the Director Plan, or any part thereof, at any time and for
any  reason.  No such  action  by the  Board  may  alter or  impair  any  option
previously  granted under the Director  Plan without the written  consent of the
optionee. The Company shall obtain stockholder approval for any amendment to the
Director Plan to the extent  necessary  and desirable to comply with  applicable
law. Unless terminated earlier, the Director Plan shall terminate ten years from
the date of its  approval  by the  stockholders  or the  Board  of the  Company,
whichever is earlier.

Federal Income Tax Consequences

     Nonstatutory  Stock  Options.  An optionee  does not  recognize any taxable
income  at the time he or she is  granted  a  nonstatutory  stock  option.  Upon
exercise,  the optionee  recognizes  taxable  income  generally  measured by the
excess of the then fair market value of the shares over the exercise price. Upon
a disposition of such shares by the optionee,  any  difference  between the sale
price and the optionee's exercise price, to the extent not recognized as taxable
income as provided above, is treated as long-term or short-term  capital gain or
loss,  depending on the holding  period.  Net capital  gains on shares held more
than 12 months may be taxed at a maximum federal rate of 20%. Capital losses are
allowed in full against capital gains and up to $3,000 against other income.

     The  foregoing is only a summary of the effect of federal  income  taxation
upon optionees and the Company with respect to the grant and exercise of options
under the  Director  Plan.  It does not  purport  to be  complete,  and does not
discuss the tax  consequences  of the director's  death or the provisions of the

                                  PROPOSAL FOUR
                 AMENDMENT OF 1996 EMPLOYEE STOCK PURCHASE PLAN


     The  Company's  Board of  Directors  (the  "Board") and  stockholders  have
previously  adopted and approved the Company's 1996 Employee Stock Purchase Plan
("Purchase  Plan")  (described  below).  In April  1999,  the Board  approved an
amendment to the Purchase Plan, subject to stockholder approval, to increase the
shares reserved for issuance  thereunder by 100,000  shares,  bringing the total
number of shares  issuable  under the Purchase Plan to 220,000.  As of March 31,
1999, 48,000 shares were available for future issuance under the Purchase Plan.

     At the Annual  Meeting,  the  stockholders  are being  asked to approve the
increase in the number of shares issuable under the Purchase Plan.

Summary of the Purchase Plan

     General.  The purpose of the Purchase Plan is to provide  employees with an
opportunity to purchase Common Stock of the Company through payroll deductions.

     Administration.  The  Purchase  Plan may be  administered  by the  Board of
Directors (the "Board") or a committee  appointed by the Board. All questions of
interpretation  or  application of the Purchase Plan are determined by the Board
or its appointed committee,  and its decisions are final, conclusive and binding
upon all participants.

     Eligibility.  Each  employee of the  Company  (including  officers),  whose
customary employment with the Company is at least twenty (20) hours per week and
more than five (5) months in any calendar  year, is eligible to  participate  in
the  Purchase  Plan;  provided,  however,  that no employee  shall be granted an
option under the Purchase  Plan (i) to the extent  that,  immediately  after the
grant,  such  employee  would own 5% of either the voting  power or value of the
stock of the  Company,  or (ii) to the extent that his or her rights to purchase
stock under all employee stock  purchase plans of the Company  accrues at a rate
which exceeds $25,000 worth of stock (determined at the fair market value of the
shares at the time such option is granted) for each calendar year.

     Offering  Period.  The Purchase  Plan is  implemented  by offering  periods
lasting  approximately  six  months  in  duration  with  a new  offering  period
commencing on May 1 and November 1 of each year. To  participate in the Purchase
Plan, each eligible employee must authorize payroll  deductions  pursuant to the
Purchase Plan.  Such payroll  deductions  may not exceed 10% of a  participant's
compensation.  Compensation  is defined as base straight time gross earnings and
commissions,  but exclusive of overtime, shift premium,  incentive compensation,
bonuses and other  compensation.  Once an employee  becomes a participant in the
Purchase Plan,  Common Stock will  automatically be purchased under the Purchase
Plan at the end of each offering  period,  unless the  participant  withdraws or
terminates  employment earlier, and the employee will automatically  participate
in each  successive  offering  period until such time as the employee  withdraws
from the Purchase Plan or the employee's employment with the Company terminates.

     Purchase  Price.  The purchase price per share at which shares will be sold
in an  offering  under  the  Purchase  Plan is the  lower of (i) 85% of the fair
market value of a share of Common  Stock on the first day of an offering  period
or (ii) 85% of the fair market  value of a share of Common Stock on the last day
of each  offering  period.  The fair market value of the Common Stock on a given
date is generally  the closing sale price of the Common Stock as reported on the
Nasdaq National Market for such date.

     Payment of Purchase Price;  Payroll  Deductions.  The purchase price of the
shares is accumulated by payroll deductions  throughout the offering period. The
number of shares of Common Stock a  participant  may  purchase in each  offering
period is determined by dividing the total amount of payroll deductions withheld
from the participant's  compensation during that offering period by the purchase
price; provided, however, that a participant may not purchase during an offering
period more than a number of shares  determined by dividing  $12,500 by the fair
market value of a share of the Company's  Common Stock on the  enrollment  date.
During  the  offering   period,   a  participant  may  discontinue  his  or  her
participation  in the  Purchase  Plan,  and may decrease or increase the rate of
payroll deductions in an offering period within limits set by the Administrator.


                                       11
<PAGE>


     All  payroll  deductions  made  for  a  participant  are  credited  to  the
participant's account under the Purchase Plan, are withheld in whole percentages
only and are included with the general funds of the Company.  Funds  received by
the Company  pursuant to  exercises  under the  Purchase  Plan are also used for
general corporate  purposes.  A participant may not make any additional payments
into his or her account.

     Withdrawal.  A participant  may terminate his or her  participation  in the
Purchase Plan at any time by giving the Company a written  notice of withdrawal.
In such event, the payroll deductions credited to the participant's account will
be returned, without interest, to such participant.  Payroll deductions will not
resume unless a new  subscription  agreement is delivered in  connection  with a
subsequent offering period.

     Termination of Employment.  Termination of a  participant's  employment for
any reason,  including death,  cancels his or her  participation in the Purchase
Plan  immediately.  In  such  event  the  payroll  deductions  credited  to  the
participant's account will be returned without interest to such participant, his
or her designated beneficiaries or the executors or administrators of his or her
estate.

     Adjustments Upon Changes in Capitalization.  In the event of any changes in
the  capitalization  of the Company effected without receipt of consideration by
the  Company,   such  as  a  stock  split,   stock   dividend,   combination  or
reclassification  of the Common  Stock,  resulting in an increase or decrease in
the number of shares of Common Stock,  proportionate adjustments will be made by
the Board in the shares subject to purchase and in the price per share under the
Purchase Plan. In the event of  liquidation  or dissolution of the Company,  the
offering  periods  then in  progress  will  terminate  immediately  prior to the
consummation of such event unless otherwise  provided by the Board. In the event
of a sale of all or  substantially  all of the  assets  of the  Company,  or the
merger of the Company with or into another corporation, the offering period then
in  progress  will be  shortened  and a new  exercise  date will be set. In such
event,  the Board shall notify each  participant at least ten (10) business days
prior to the new exercise date.

     Amendment  and  Termination.  The Board may at any time and for any  reason
amend or terminate  the Purchase  Plan,  except that no such  termination  shall
affect options  previously  granted and no amendment shall make any change in an
option  granted  prior  thereto  which  adversely  affects  the  rights  of  any
participant.  Stockholder  approval for amendments to the Purchase Plan shall be
obtained  in such a manner and to such a degree as  required  to comply with all
applicable laws or regulations. The Purchase Plan will terminate in 2006, unless
terminated earlier by the Board in accordance with the Purchase Plan.

     Certain Federal Income Tax Information.  The following brief summary of the
effect of federal  income  taxation  upon the  participant  and the Company with
respect to the shares  purchased  under the Purchase Plan does not purport to be
complete,  and does not discuss the tax consequences of a participant's death or
the income tax laws of any state or foreign country in which the participant may
reside.

     The  Purchase  Plan,  and the  right  of  participants  to  make  purchases
thereunder,  is intended to qualify under the provisions of Sections 421 and 423
of the Code. Under these provisions,  no income will be taxable to a participant
until  the  shares  purchased  under  the  Purchase  Plan are sold or  otherwise
disposed of. Upon sale or other disposition of the shares,  the participant will
generally be subject to tax in an amount that  depends upon the holding  period.
If the shares  are sold or  otherwise  disposed  of more than two years from the
first day of the  applicable  offering  period and one year from the  applicable
date of purchase, the participant will recognize ordinary income measured as the
lesser of (a) the excess of the fair  market  value of the shares at the time of
such sale or disposition  over the purchase price, or (b) an amount equal to 15%
of the fair  market  value of the  shares as of the first day of the  applicable
offering period.  Any additional gain will be treated as long-term capital gain.
If the shares are sold or otherwise  disposed of before the  expiration of these
holding  periods,  the  participant  will recognize  ordinary  income  generally
measured  as the excess of the fair  market  value of the shares on the date the
shares are purchased over the purchase  price.  Any  additional  gain or loss on
such sale or disposition  will be long-term or short-term  capital gain or loss,
depending  on the holding  period.  The Company  generally  is not entitled to a
deduction for amounts taxed as ordinary  income or capital gain to a participant
except to the extent of ordinary income  recognized by participants  upon a sale
or  disposition  of  shares  prior  to the  expiration  of the  holding  periods
described above.

Stock Option Information

      Option Grants in Last Fiscal Year. The following  table sets forth certain
information  concerning  grants of stock  options to each of the Named  Officers
during  the fiscal  year  ended  December  31,  1998.  The table also sets forth
hypothetical  gains or  "option  spreads"  for the  options  at the end of their
respective  ten-year terms. These gains are based on the assumed rates of annual
compound  stock  price  appreciation  of 5% and 10% from the date the option was
granted over the full option term. Actual gains, if any, on option exercises are
dependent on the future  performance  of the Company's  Common Stock and overall
market conditions.

     Company's  Common Stock is listed on the Nasdaq National  Market,  the fair
     market value is the closing sale price for the Common Stock.  Non-qualified
     options  may be  granted at an  exercise  price of no less than 85% of fair
     market value on the date of grant.  Options generally become exercisable as
     to 25% of the  shares  subject  to the  option  one year  after the date of
     grant,  and as to the  remainder  in equal  monthly  installments  over the
     succeeding 36 months.  Options generally terminate on the earlier of thirty
     days after  termination of the optionee's  employment by or services to the
     Company, or ten years after grant.

                      REPORT OF THE COMPENSATION COMMITTEE

     The  Compensation  Committee  (the  "Committee")  of the Board of Directors
reviews and  recommends  to the Board of Directors  for  approval the  Company's
executive   compensation  policies.  The  Committee  during  1998  consisted  of
directors  David  Schnell,  M.D.,  John P. Walker and L. James  Strand,  M.D. (a
director of the Company  until April 13,  1998).  The following is the report of
the Committee describing the compensation  policies and rationales applicable to
the Company's executive officers with regard to the compensation payable to such
executive officers for the fiscal year ended December 31, 1998.

Compensation Philosophy

     The goal of the  Company's  compensation  policies  is to  align  executive
compensation with business objectives and corporate performance,  and to attract
and retain  executives who contribute to the long-term  success and value of the
Company.  Compensation for the Company's  executive  officers consists of a base
salary and potential  cash bonus,  as well as potential  incentive  compensation
through stock  options and stock  ownership.  The Committee  considers the total
current  and  potential  long-term  compensation  of each  executive  officer in
establishing each element of compensation.

Base Salary

     The base salary  component  is designed to  compensate  executive  officers
competitively at levels necessary to attract and retain qualified  executives in
the pharmaceutical and biotechnology  industry. The base salary for each officer
is set on the basis of  personal  performance,  the salary  levels in effect for
comparable  positions within the Company's principal  competitors,  and internal
comparability  considerations.  As a general  matter,  the base  salary for each
executive officer is initially  established  through negotiation at the time the
officer is hired, taking into account such officer's qualifications, experience,
prior salary, and competitive salary  information.  Year-to-year  adjustments to
each executive officer's base salary


                                       18
<PAGE>


are based upon  personal  performance  for the year and  changes in the  general
level of base salaries of persons in comparable positions within the industry.

Incentive Bonuses

     The Company  implemented a formal  incentive bonus plan in 1997 pursuant to
which the  executive  officers of the Company are eligible to receive  incentive
cash compensation based upon achievement of corporate goals. The amounts of such
cash bonuses for executive  officers other than the Chief Executive  Officer are
based upon the recommendation of the Chief Executive Officer,  subject to review
and  approval of the  Compensation  Committee  and the Board of  Directors.  The
amount of any cash bonus for the Chief  Executive  Officer is  determined by the
Compensation  Committee  subject  to the  review  and  approval  of the Board of
Directors.

Long-Term Incentives

     The Committee  provides the  Company's  executive  officers with  long-term
incentive  compensation through grants of stock options under the Company's 1993
Amended  Incentive  Stock Plan and the  opportunity  to purchase stock under the
1996 Employee Stock Purchase Plan (the "Purchase Plan").  The Committee believes
that stock options provide the Company's executive officers with the opportunity
to purchase and  maintain an equity  interest in the Company and to share in the
appreciation of the value of the Company's Common Stock. The Committee  believes
that  stock  options  directly  motivate  an  executive  to  maximize  long-term
stockholder  value.  The options also utilize  vesting  periods  (generally four
years) that  encourage key  executives to continue in the employ of the Company.
All options granted to executive  officers to date have been granted at the fair
market value of the Company's  Common Stock on the date of grant.  The Committee
considers the grant of each option subjectively, considering factors such as the
individual  performance  of the executive  officer and the past and  anticipated
future  contribution of the executive officer to the attainment of the Company's
long-term  strategic  performance goals.  Long-term  incentives granted in prior
years are also taken into consideration.

     The Company  established  the Purchase Plan both to encourage  employees to
continue  in  the  employ  of the  Company  and to  motivate  employees  through
ownership  interest in the  Company.  Under the  Purchase  Plan,  employees  may
purchase Common Stock through payroll  deductions in semi-annual  offerings at a
price equal to the lower of 85% of the closing price on the applicable  offering
commencement  date  or 85% of  the  closing  price  on the  applicable  offering
termination  date.  The Company has reserved  120,000 shares of Common Stock for
issuance  to  employees.  In April  1999,  the Board of  Directors  approved  an
amendment to the Purchase Plan, subject to stockholder approval, to increase the
shares reserved for issuance thereunder to 220,000 shares.

Chief Executive Officer Compensation

     The compensation of the Chief Executive Officer is reviewed annually on the
same basis as discussed  above for all  executive  officers.  In 1998,  James E.
Rurka's base salary was  increased  from  $280,000 to  $290,000,  an increase of
3.5%.  Mr. Rurka  received a $25,000 bonus in 1999 relative to 1998  performance
and was not awarded a bonus in 1998 relative to 1997 performance.  As with other
executive  officers,  Mr. Rurka's total  compensation was based on the Company's
accomplishments and the Chief Executive Officer's contribution thereto.

Section 162(m)

     The Board has considered the potential  future effects of Section 162(m) of
the Internal  Revenue Code on the compensation  paid to the Company's  executive
officers.  Section  162(m)  disallows  a tax  deduction  for any  publicly  held
corporation  for individual  compensation  exceeding $1.0 million in any taxable
year for any of the  executive  officers  named in the Proxy  Statement,  unless
compensation is performance-based.  The Company has adopted a policy that, where
reasonably   practicable,   the  Company  will  seek  to  qualify  the  variable
compensation  paid  to  its  executive   officers  for  an  exemption  from  the
deductibility limitations of Section 162(m).



                                       19
<PAGE>


     In  approving  the  amount  and  form of  compensation  for  the  Company's
executive officers,  the Committee will continue to consider all elements of the
cost to the Company of providing  such  compensation,  including  the  potential
impact of Section 162(m).

     The Company  believes  that the  transactions  set forth above were made on
terms no less  favorable  to the  Company  than  could have been  obtained  from
unaffiliated third parties.  All future  transactions,  including loans, between
the  Company  and its  officers,  directors,  principal  stockholders  and their
affiliates will be approved by a majority of the Board of Directors, including a
majority  of the  independent  and  disinterested  outside  directors  and  will
continue to be on terms no less  favorable to the Company than could be obtained

           COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

     During 1998, the Compensation  Committee consisted of David Schnell,  M.D.,
John P. Walker and L. James Strand,  M.D. (a director of the Company until April
13,  1998).  No  interlocking  relationship  exists  between  any  member of the
Company's  Board of Directors or  Compensation  Committee  and any member of the
Board of Directors or Compensation  Committee of any other Company. No member of
the Compensation  Committee, as constituted during 1998, was a former or current
officer or employee of the Company.

                COMPLIANCE WITH SECTION 16(A) OF THE EXCHANGE ACT

     Section  16(a) of the  Exchange Act  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 on Form 3 and
changes in ownership on Form 4 or Form 5 with the SEC. Such officers,  directors
and 10%  stockholders are also required by SEC rules to furnish the Company with
copies of all Section 16(a) forms they file.

     Based  solely on its review of the copies of such forms  received by it, or
written  representations  from certain reporting  persons,  the Company believes
that,  during the fiscal year ended  December 31, 1998, all Section 16(a) filing
requirements  applicable to its officers,  directors and 10%  stockholders  were
complied with.


                                LEGAL PROCEEDINGS

               The Company is not a party to any legal proceeding.


                           CORPORATE PERFORMANCE GRAPH

     The  following  graph shows a comparison of  cumulative  total  stockholder
return on the Company's  Common Stock from the  effective  date of the Company's
initial  public  offering  on May 14,  1996  through  December  31, 1998 for the
Company, the Nasdaq National Market Index and the Nasdaq  Pharmaceutical  Index.
The Nasdaq  Pharmaceutical  Index represents all companies trading on the Nasdaq
National Market under the Standard Industrial Code for pharmaceutical companies,
including biotechnology companies. The graph is presented pursuant to SEC rules.
The Company  believes  that while total  stockholder  return can be an important
indicator of corporate performance, the stock prices of companies like Microcide
are  subject  to  a  number  of   market-related   factors  other  than  company
performance, such as competitive announcements,  mergers and acquisitions in the
industry,  the general state of the economy and the prices of  biopharmaceutical
stocks.
