EXHIBIT 10.21

                             AMGEN INC.

             AMENDED AND RESTATED 1988 STOCK OPTION PLAN


    1.   PURPOSE.
         (a)  The purpose of the Plan is to provide a means by which
selected  employees  and  directors   (if  declared  eligible   under
paragraph 4) of and consultants to Amgen Inc., a Delaware corporation
(the "Company"), and its Affiliates, as defined in subparagraph 1(b),
directly or  indirectly  through  trusts for  the  benefit  of  their
families, may  be  given an  opportunity  to purchase  stock  of  the
Company.
         (b)  The word "Affiliate"  as used  in the  Plan means  any
parent corporation or subsidiary corporation of the Company, as those
terms are defined in  Sections 424(e) and  (f), respectively, of  the
Internal Revenue Code of 1986, as amended (the "Code").
         (c)  The Company, by means of the Plan, seeks to retain the
services of persons now holding positions,  to secure and retain  the
services of persons capable of filling such positions, and to provide
incentives for such persons to exert maximum efforts for the  success
of the Company.
         (d)  The Company intends that the options  issued under the
Plan shall,  in the  discretion  of the  Board  of Directors  of  the
Company (the "Board") or any committee to which responsibility for
administration of the Plan has been delegated pursuant to subparagraph
2(c), be either incentive stock options as that term is used in Section
422 of the Code ("Incentive Stock  Options"),  or options  which  do not
qualify as Incentive Stock Options ("Nonqualified Stock Options").  All
options shall be separately designated Incentive Stock Options or 
Nonqualified Stock Options at the time of grant, and in such form  as
issued pursuant  to  paragraph  5,  and  a  separate  certificate  or
certificates shall be issued for shares purchased on exercise of each
type of option.  An option designated as a Nonqualified Stock  Option
shall not be treated as an Incentive Stock Option.
               The word  "Trust" as  used in  the Plan  shall mean  a
trust created for the benefit of  the employee or consultant, his  or
her spouse, or members of their immediate family.  The word  optionee
shall mean the person to whom  the option is granted or the  employee
or consultant for whose benefit the option is granted to a Trust,  as
the context shall require.

    2.   ADMINISTRATION.
         (a)  The Plan shall be administered by the Board unless and
until the Board delegates administration to a committee, as  provided
in subparagraph 2(c).
         (b)  The Board shall have the power, subject to, and within
the limitations of, the express provisions of the Plan:
              (1)  To determine  from  time  to  time which  of  the
persons eligible under the Plan shall be granted options; when and how
the option shall be granted; whether the option will be an Incentive

Stock Option or a Nonqualified Stock  Option; the provisions of  each
option granted (which need not be  identical), including the time  or
times during the term of each option within which all or portions  of
such option may be exercised; and  the number of shares for which  an
option shall be granted to each such person.
              (2)  To construe  and interpret  the Plan  and options
granted under  it,  and to  establish,  amend and  revoke  rules  and
regulations for its administration.   The Board,  in the exercise  of
this power, may correct any defect, omission or inconsistency in  the
Plan or in any  option agreement, in  a manner and  to the extent  it
shall deem necessary or expedient to make the Plan fully effective.
              (3)  To amend the Plan as provided in paragraph 11.
              (4)  Generally, to exercise such powers and to perform
such acts as the  Board deems necessary or  expedient to promote  the
best interests of the Company.
         (c)  The Board may delegate administration of the Plan to a
committee composed of not fewer than  three (3) members of the  Board
(the "Committee"), all  of the members  of which  Committee shall be
disinterested persons, if required and  as defined by the  provisions
of subparagraph 2(d).  If administration is delegated to a Committee,
the Committee shall  have, in connection  with the administration  of
the Plan, the  powers theretofore  possessed by  the Board,  subject,
however, to such resolutions, not inconsistent with the provisions of
the Plan, as  may be adopted  from time to  time by the  Board.   The
Board may abolish the Committee at  any time and revest in the  Board
the administration of the Plan.
         (d)  The term "disinterested person", as used in this Plan,
shall mean an  administrator of  the Plan,  whether a  member of  the
Board or of any Committee to which responsibility for  administration
of the Plan has  been delegated pursuant to  subparagraph 2(c):   (i)
who  is  not  at  the  time   he  or  she  exercises  discretion   in
administering the Plan eligible  and has not at  any time within  one
(1) year prior  thereto been eligible  for selection as  a person  to
whom stock  may  be allocated  or  to  whom stock  options  or  stock
appreciation rights may be granted pursuant to the Plan or any  other
plan  of  the  Company  or  any  of  its  Affiliates  entitling   the
participants  therein  to  acquire  stock,  stock  options  or  stock
appreciation rights of the Company or any of its Affiliates; or  (ii)
who is  otherwise  considered  to  be  a  "disinterested  person"  in
accordance with  the rules,  regulations  or interpretations  of  the
Securities and Exchange Commission.  Any such person shall  otherwise
comply with  the requirements  of Rule  16b-3 promulgated  under  the
Securities Exchange Act of 1934, as amended (the "Exchange Act"),  as
from time to time in effect.
         (e)  Any requirement that an administrator of the Plan be a
"disinterested person" shall not apply if the Board or the  Committee
expressly declares that such requirement shall not apply.

    3.   SHARES SUBJECT TO THE PLAN.
         (a)  Subject to the provisions  of paragraph 9  relating to
adjustments upon  changes  in  stock, the  stock  that  may  be  sold
pursuant to options granted  under the Plan shall  not exceed in  the
aggregate Thirty Six Million (36,000,000) shares of the Company's $.0001
par value common stock (the "Common Stock").   If any option granted
under the Plan shall for any reason expire or otherwise terminate without

having been exercised in full, the  Common Stock not purchased  under
such option shall again become available for the Plan.
         (b)  The Common Stock subject  to the Plan may  be unissued
shares or reacquired shares, bought on the market or otherwise.
         (c)  An  Incentive  Stock  Option  may  be  granted  to  an
eligible person  under the  Plan only  if the  aggregate fair  market
value (determined  as of  the times  the respective  Incentive  Stock
Options are  granted)  of the  Common  Stock with  respect  to  which
Incentive Stock Options are  exercisable for the  first time by  such
optionee during any calendar year under all such plans of the Company
and its  Affiliates  does not  exceed  one hundred  thousand  dollars
($100,000).  Should it be determined that any portion of an Incentive
Stock Option granted under the Plan does not qualify for treatment as
an Incentive Stock Option by reason  of exceeding such maximum,  such
option shall be considered a Nonqualified Stock Option to the extent,
but only to the extent, of such excess.  Should it be determined that
an entire option does not qualify for treatment as an Incentive Stock
Option,  such  option  shall,  in  its  entirety,  be  considered   a
Nonqualified Stock Option.

    4.   ELIGIBILITY.
         (a)  Incentive  Stock  Options  may  be  granted   only  to
employees of the Company or its Affiliates, and a director or officer
of the  Company shall  not be  eligible  to receive  Incentive  Stock
Options unless such director  or officer is also  an employee of  the
Company or any Affiliate.  Nonqualified Stock Options may be  granted
only  to  employees  of,  or  consultants  to,  the  Company  or  its
Affiliates (including directors  or officers  who so  qualify) or  to
Trusts of any such employee or consultant.
         (b)  A director  shall  in no  event  be eligible  for  the
benefits of  the Plan  unless and  until such  director is  expressly
declared eligible to participate in the  Plan by action of the  Board
or the Committee, and only if, at any time discretion is exercised by
the Board or the Committee in the selection of a director as a person
to whom options may be granted, or in the determination of the number
of shares which may be covered by options granted to a director:  (i)
a majority of  the Board and  a majority of  the directors acting  in
such matter  are disinterested  persons, as  defined in  subparagraph
2(d); (ii) the Committee  consists solely of "disinterested  persons"
as defined in subparagraph 2(d); or (iii) the Plan otherwise complies
with the requirements  of Rule 16b-3  promulgated under the  Exchange
Act, as  from time  to time  in effect.   The  Board shall  otherwise
comply with  the requirements  of Rule  16b-3 promulgated  under  the
Exchange Act, as from time to time in effect.
         (c)  No person  shall  be  eligible  for the  grant  of  an
Incentive Stock Option under the Plan if, at the time of grant,  such
person owns (or is  deemed to own pursuant  to Section 424(d) of  the
Code) stock  possessing more  than ten  percent  (10%) of  the  total
combined voting power of  all classes of stock  of the Company or  of
any of its  Affiliates unless the  exercise price  of such  Incentive
Stock Option is at  least one hundred and  ten percent (110%) of  the
fair market value of the  Common Stock at the  date of grant and  the
term of the  Incentive Stock Option  does not exceed  five (5)  years
from the date of grant.

    5.   OPTION PROVISIONS.
         Each option shall be  in suc h form and  shall contain such
terms and  conditions  as  the Board  or  the  Committee  shall  deem
appropriate.    The  provisions  of  separate  options  need  not  be
identical, but each  option shall include  (through incorporation  of
provisions hereof  by  reference  in the  option  or  otherwise)  the
substance of each of the following provisions:
         (a)  No option shall be exercisable after the expiration of
ten (10) years from the date it was granted.
         (b)  The exercise  price  of  each Incentive  Stock  Option
shall be not less than one hundred percent (100%) of the fair  market
value of  the Common  Stock subject  to the  option on  the date  the
option is granted.   The exercise  price of  each Nonqualified  Stock
Option shall be not less than  eighty-five percent (85%) of the  fair
market value of the  Common Stock subject to  the option on the  date
the option is granted.
         (c)  The purchase price  of Common Stock  acquired pursuant
to an option  shall be paid,  to the extent  permitted by  applicable
statutes and regulations, either:  (i) in cash at the time the option
is exercised;  or  (ii)  at  the  discretion  of  the  Board  or  the
Committee, either at the time of grant or exercise of the option  (A)
by delivery to the Company of other Common Stock of the Company,  (B)
according to  a  deferred payment  or  other arrangement  (which  may
include, without limiting the generality of the foregoing, the use of
other Common Stock of the Company) with the person to whom the option
is  granted  or  to  whom  the  option  is  transferred  pursuant  to
subparagraph 5(d), or (C)  in any other  form of legal  consideration
that may  be  acceptable to  the  Board  or the  Committee  in  their
discretion.
    In the case of any deferred payment arrangement,  interest shall
be payable at least  annually and shall be  charged at not less  than
the minimum  rate of  interest necessary  to avoid  the treatment  as
interest, under any applicable provisions of the Code, of any amounts
other than amounts stated to be  interest under the deferred  payment
arrangement.
         (d)  An  option  granted  to  a  natural  person  shall  be
exercisable during the lifetime of such  person only by such  person,
provided that such person during such person's lifetime may designate
a Trust to be such person's beneficiary with respect to any Incentive
Stock Options granted after February 25, 1992 and with respect to any
Nonqualified Stock  Options, and  such beneficiary  shall, after  the
death of the  person to  whom the option  was granted,  have all  the
rights that  such person  has while  living, including  the right  to
exercise the option.  In the  absence of such designation, after  the
death of the person to whom  the option is granted, the option  shall
be exercisable by the person or persons to whom the optionee's rights
under such  option  pass  by will  or  by  the laws  of  descent  and
distribution.
         (e)  The total number of shares of Common  Stock subject to
an option may,  but need not,  be allotted  in periodic  installments
(which may, but need not, be equal).   From time to time during  each
of such installment periods, the option may be exercised with respect
to some or  all of the  shares allotted to  that period, and/or  with
respect to some or all of the shares allotted to any prior period  as
to which the option was not fully exercised.  During the remainder of the
term of the option (if its term extends beyond the end of the installment

periods), the option may be exercised from time to time with  respect
to any shares then remaining subject  to the option.  The  provisions
of this  subparagraph  5(e)  are subject  to  any  option  provisions
governing the minimum number of shares  as to which an option may  be
exercised.
         (f)  The Company may require any optionee, or any person to
whom an option is transferred under subparagraph 5(d), as a condition
of exercising  any  such  option:  (1)  to  give  written  assurances
satisfactory to  the  Company  as to  the  optionee's  knowledge  and
experience in  financial  and business  matters  and/or to  employ  a
purchaser representative  who has  such knowledge  and experience  in
financial and business  matters, and  that he  or she  is capable  of
evaluating, alone or  together with  the purchaser's  representative,
the merits  and risks  of  exercising the  option;  and (2)  to  give
written assurances  satisfactory to  the  Company stating  that  such
person is acquiring the Common Stock  subject to the option for  such
person's own account and not with any present intention of selling or
otherwise distributing the Common Stock.  These requirements, and any
assurances given pursuant to such requirements, shall be  inoperative
if: (i) the issuance  of the shares upon  the exercise of the  option
has been  registered under  a then  currently effective  registration
statement  under  the  Securities  Act  of  1933,  as  amended   (the
"Securities Act");  or  (ii)  as to  any  particular  requirement,  a
determination  is  made  by  counsel   for  the  Company  that   such
requirement need  not be  met in  the  circumstances under  the  then
applicable securities law.
         (g)  An option  shall  terminate  three  (3)  months  after
termination  of  the  optionee's  employment  or  relationship  as  a
consultant with  the  Company  or  an  Affiliate,  unless:  (i)  such
termination is due to such  person's permanent and total  disability,
within the meaning of  Section 422(c)(6) of the  Code, in which  case
the option may, but need not, provide that it may be exercised at any
time within one (1) year following such termination of employment or
relationship as a  consultant; (ii) the  optionee dies  while in  the
employ of  or while  serving as  a consultant  to the  Company or  an
Affiliate, or within not more than three (3) months after termination
of such employment or relationship as a consultant, in which case the
option may, but  need not, provide  that it may  be exercised at  any
time within eighteen (18) months following the death of the  optionee
by the person  or persons to  whom the optionee's  rights under  such
option pass by will  or by the laws  of descent and distribution;  or
(iii) the option  by its  terms specifies  either (A)  that it  shall
terminate sooner  than  three (3)  months  after termination  of  the
optionee's employment or relationship as a consultant, or (B) that it
may be exercised more than three (3) months after termination of  the
optionee's employment  or  relationship  as  a  consultant  with  the
Company or  an  Affiliate.   This  subparagraph  5(g)  shall  not  be
construed to extend  the term of  any option or  to permit anyone  to
exercise the option  after expiration of  its term, nor  shall it  be
construed to increase the number of shares as to which any option  is
exercisable from the amount exercisable on the date of termination of
the optionee's employment or relationship as a consultant.
         (h)  The option  may,  but need  not,  include a  provision
whereby the optionee may elect at any time during the term of his  or
her employment or relationship  as a consultant  with the Company  or
any Affiliate to exercise the option as to any part or all of the shares

subject to the option prior to the stated vesting date of the  option
or of any installment or installments  specified in the option.   Any
shares so purchased from  any unvested installment  or option may  be
subject to a repurchase right in favor of the Company or to any other
restriction the Board or the Committee determines to be appropriate.
         (i)  To the extent provided by the terms of  an option, the
optionee may  satisfy any  federal, state  or local  tax  withholding
obligation relating to  the exercise  of such  option by  any of  the
following means or by  a combination of such  means: (1) tendering  a
cash payment; (2) authorizing the Company to withhold from the shares
of the Common Stock otherwise issuable to the participant as a result
of the exercise of the stock option a number of shares having a  fair
market value less than or equal to the amount of the withholding  tax
obligation; or (3) delivering to  the Company owned and  unencumbered
shares of the Common  Stock having a fair  market value less than  or
equal to the amount of the withholding tax obligation.
         (j)  Without in any way limiting the authority of the Board
or Committee to make or not to make grants of Options hereunder,  the
Board or Committee shall have the  authority (but not an  obligation)
to include  as part  of any  Option  agreement, and  all  outstanding
Nonqualified Stock Options, to the extent there are unvested  options
on June 30, 1991, shall be amended to include, a provision  entitling
the optionee to a  further Option (a "Re-Load  Option") in the  event
the optionee exercises the Option evidenced by the Option  agreement,
in whole or in part, by surrendering other shares of Common Stock  in
accordance with this Plan and the terms and conditions of the  Option
agreement.  Any  such Re-Load  Option (i) shall  be for  a number  of
shares equal to the  number of shares surrendered  as part or all  of
the exercise price of  such Option (or  surrendered for shares  which
were unvested on June 30, 1991 in the case of an amended Nonqualified
Stock Option); (ii) shall have an  expiration date which is the  same
as the expiration date of the Option the exercise of which gave  rise
to such Re-Load Option; (iii) shall  have an exercise price which  is
equal to one hundred percent (100%)  of the fair market value of  the
Common Stock subject to the Re-Load Option on the date of exercise of
the original Option or, in the case  of a Re-Load Option which is  an
Incentive Stock Option and which is granted to a 10% stockholder  (as
defined in subparagraph 4(c)), shall have an exercise price which  is
equal to one hundred and ten percent (110%) of the fair market  value
of the Common  Stock subject  to the Re-Load  Option on  the date  of
exercise of the original Option; and (iv) shall be granted under this
Plan, if sufficient shares are  available under subparagraph 3(a)  of
the Plan,  and  if sufficient  shares  of  Common Stock  are  not  so
available, shall be granted under the  1991 Equity Incentive Plan  to
the extent shares of Common Stock are available under that Plan.
    Any such Re-Load Option  may be an Incentive  Stock Option or  a
Nonqualified Stock Option, as the Board or Committee may designate at
the time of the grant of the original Option, except that all Re-Load
Options on unvested  shares (as of  June 30,  1991) of  Non-Qualified
Stock Options shall be Nonqualified Stock Options, provided, however,
that the  designation of  any Re-Load  Option as  an Incentive  Stock
Option  shall  be  subject  to  the  one  hundred  thousand   dollars
($100,000) annual  limitation on  exercisability of  Incentive  Stock
Options described in subparagraph 3(c) of the Plan and in Section 422(d)

of the Code.   There shall be no Re-Load Options on a Re-Load  Option.
Any such  Re-Load Option  shall be  subject  to the  availability  of
sufficient shares under subparagraph 3(a) of  this Plan or under  the
1991 Equity Incentive Plan and shall  be subject to such other  terms
and conditions as the Board or Committee may determine.

    6.   COVENANTS OF THE COMPANY.
         (a)  During the  terms  of the  options  granted under  the
Plan, the Company  shall keep available  at all times  the number  of
shares of stock required to satisfy such options.
         (b)  The Company shall seek to obtain  from each regulatory
commission or agency having jurisdiction over the Plan such authority
as may be required to issue and sell shares of stock upon exercise of
the options  granted under  the Plan;  provided, however,  that  this
undertaking shall  not  require the  Company  to register  under  the
Securities Act either the Plan, any option granted under the Plan  or
any Common Stock issued or issuable pursuant to any such option.  If,
after reasonable efforts, the  Company is unable  to obtain from  any
such regulatory commission or agency the authority which counsel  for
the Company deems necessary for the lawful issuance and sale of stock
under the Plan, the Company shall be relieved from any liability  for
failure to issue and sell stock upon exercise of such options  unless
and until such authority is obtained.

    7.   USE OF PROCEEDS FROM STOCK.
         Proceeds from the sale of Common Stock pursuant  to options
granted under the Plan shall constitute general funds of the Company.

    8.   MISCELLANEOUS.
         (a)  The Board or  the Committee  shall have  the power  to
accelerate the time during  which an option may  be exercised or  the
time during which an option or any part thereof will vest pursuant to
subparagraph 5(e),  notwithstanding  the  provisions  in  the  option
stating the time during which it may be exercised or the time  during
which it will vest.   Each option providing  for vesting pursuant  to
subparagraph  5(e)  shall  also  provide  that  if  the  employee  or
consultant should die during the term  of his or her employment  with
the Company  or  his  or  her  affiliation  with  the  Company  as  a
consultant, the vesting schedule of options granted to such  employee
or consultant or to the Trusts  of such employee or consultant  shall
be accelerated by twelve months for  each full year the employee  has
been employed  by or  the consultant  has  been affiliated  with  the
Company.   Options granted  under the  Plan that  are outstanding  on
February 25,  1992,  shall  be amended  to  include  the  accelerated
vesting provided  for in  the preceding  sentence of  this  Paragraph
8(a).
         (b)  Neither an optionee nor  any person to whom  an option
is transferred  under subparagraph  5(d) shall  be deemed  to be  the
holder of, or to have any of the rights of a holder with respect  to,
any shares subject to  such option unless and  until such person  has
satisfied all requirements for exercise of the option pursuant to its
terms.
         (c)  Throughout the term of any option  granted pursuant to
the Plan, the  Company shall  make available  to the  holder of  such
option, not later than one hundred twenty (120) days after the close

of each of the  Company's fiscal years during  the option term,  upon
request, such financial and  other information regarding the Company
as comprises the  annual report to  the shareholders of the  Company
provided for in the bylaws of the Company.
         (d)  Nothing in  the  Plan or  any  instrument executed  or
option granted  pursuant  thereto  shall  confer  upon  any  eligible
participant or optionee any  right to continue in  the employ of  the
Company or any  Affiliate or to  continue acting as  a consultant or
shall affect the right of the  Company or any Affiliate to  terminate
the employment or consulting relationship of any eligible participant
or optionee with or without cause.  In the event that an optionee  is
permitted or  otherwise entitled  to take  a  leave of  absence,  the
Company shall have the unilateral right to (i) determine whether such
leave of absence will  be treated as a  termination of employment  or
relationship as consultant for purposes of paragraph 5(g) hereof  and
corresponding provisions of any outstanding options, and (ii) suspend
or otherwise delay the time or  times at which the shares subject  to
the option would otherwise vest.

    9.   CANCELLATION AND RE-GRANT OF OPTIONS.
         The Board  or the  Committee shall  have  the authority  to
effect, at any time and  from time to time,  with the consent of  the
affected option holders, (i) the repricing of any or all  outstanding
options under the  Plan and/or (ii)  the cancellation of  any or  all
outstanding options  under the  Plan and  the grant  in  substitution
therefor new options under  the Plan covering  the same or  different
numbers of shares  of Common  Stock but  having an  option price  per
share not  less than  eighty-five percent  (85%) of  the fair  market
value in the case of a Nonqualified Stock Option, one hundred percent
(100%) of the  fair market value  in the case  of an Incentive  Stock
Option  or,  in  the  case  of  a  10%  stockholder  (as  defined  in
subparagraph 4(c)), not less than one hundred and ten percent  (110%)
of the fair market value per share  of Common Stock on the new  grant
date.

    10.  ADJUSTMENTS UPON CHANGES IN COMMON STOCK.
         (a)  If any chang e is made in  the Common Stock subject  to
the Plan, or subject  to any option granted  under the Plan  (through
merger,  consolidation,   reorganization,   recapitalization,   stock
dividend,  dividend  in  property  other  than  cash,  stock   split,
liquidating dividend,  combination  of shares,  exchange  of  shares,
change in corporate structure or otherwise), the Plan and outstanding
options will  be  appropriately adjusted  in  the class(es)  and  the
maximum number of shares  subject to the Plan  and the class(es)  and
the number of shares and price  per share of Common Stock subject  to
outstanding options.
          (b)  Notwithstanding anything to the contrary in this Plan,
in the event of a Change  in Control (as hereinafter defined),  then,
to the extent permitted by applicable law:  (i) the time during which
options become vested shall automatically be accelerated so that  the
unvested portions of all options shall be vested prior to the  Change
in Control  and  (ii)  the  time during  which  the  options  may  be
exercised shall automatically be accelerated  to prior to the  Change
of Control.   Upon or after the acceleration of the vesting and exercise
periods, at the election of the holders of the options, the options may

be: (x) exercised or, if the surviving or acquiring corporation agrees
to assume the options or substitute similar options, (y) assumed; or (z)
replaced with substitute options.  Options not exercised, substituted
or  assumed  prior  to  or  upon  the  Change  in  Control  shall  be
terminated.
          (c)  For purposes of the Plan, a "Change of Control" shall
be deemed to have occurred at any of the following times:
               (i)  Upon  the  acquisition   (other  than  from   the
Company) by  any person,  entity or  "group," within  the meaning  of
Section 13(d) (3) or  14(d) (2) of the  Exchange Act (excluding,  for
this purpose, the Company or its affiliates, or any employee  benefit
plan of  the  Company or  its  affiliates which  acquires  beneficial
ownership  of  voting  securities  of  the  Company),  of  beneficial
ownership (within the  meaning of  Rule 13d-3  promulgated under  the
Exchange Act)  of fifty  percent (50%)  or more  of either  the  then
outstanding shares of Common  Stock or the  combined voting power  of
the Company's  then outstanding  voting securities  entitled to  vote
generally in the election of directors; or
               (ii) At the  time individuals  who, as  ofOctober  23,
1995, constitute  the Board  (the "Incumbent  Board") cease  for  any
reason to constitute at least a majority of the Board, provided  that
any person becoming a director subsequent to October 23, 1995,  whose
election, or nomination for  election by the Company's  stockholders,
was approved by a vote of at  least a majority of the directors  then
comprising the Incumbent Board (other than an election or  nomination
of an individual whose initial assumption of office is in  connection
with an  actual  or  threatened  election  contest  relating  to  the
election of the Directors of the  Company, as such terms are used  in
Rule 14A-11 of  Regulation 14A  promulgated under  the Exchange  Act)
shall be, for purposes of the Plan, considered as though such  person
were a member of the Incumbent Board; or
               (iii)     Immediately prior to the consummation by the
Company of a  reorganization, merger, consolidation,  (in each  case,
with respect  to  which persons  who  were the  stockholders  of  the
Company  immediately  prior   to  such   reorganization,  merger   or
consolidation do  not, immediately  thereafter, own  more than  fifty
percent (50%) of the combined voting power entitled to vote generally
in  the  election  of  directors   of  the  reorganized,  merged   or
consolidated company's  then  outstanding  voting  securities)  or  a
liquidation or dissolution of  the Company or of  the sale of all  or
substantially all of the assets of the Company; or
              (iv) The occurrence  of  any  other  event  which  the
Incumbent Board  in  its  sole discretion  determines  constitutes  a
Change of Control.

    11.  QUALIFIED DOMESTIC RELATIONS ORDERS
          (a)  Anything in the Plan to the contrary  notwithstanding,
rights under options  may be assigned  to an Alternate  Payee to  the
extent that a  QDRO so provides.   (The terms  "Alternate Payee"  and
"QDRO" are defined in  Subsection (c) below.)   The assignment of  an
option to an Alternate Payee pursuant to a QDRO shall not be  treated
as having caused  a new grant.   The transfer  of an Incentive  Stock
Option to  an Alternate  Payee  may, however,  cause  it to  fail  to
qualify as an Incentive Stock Option.  If an option is assigned to an
Alternate Payee, the Alternate Payee generally has the same rights as

the grantee under the terms of  the Plan; provided however, that  (1)
the option shall be  subject to the same  vesting terms and  exercise
period as  if the  option were  still  held by  the grantee,  (2)  an
Alternate Payee may not transfer an option and (3) an Alternate Payee
is ineligible for Re-Load Options.
          (b)  In the event of the Plan administrator's receipt of  a
domestic relations  order or  other notice  of  adverse claim  by  an
Alternate Payee of a grantee of  an option, transfer of the  proceeds
of the exercise of such option, whether in the form of cash, stock or
other property, may be suspended.  Such proceeds shall thereafter  be
transferred pursuant  to  the terms  of  a QDRO  or  other  agreement
between the  grantee and  Alternate Payee.   A  grantee's ability  to
exercise an option may be barred if the Plan administrator receives a
court order directing the Plan administrator not to permit exercise.
          (c)  The word "QDRO" as used in the Plan shall mean a court
order (1) that creates or recognizes the right of the spouse,  former
spouse or  child  (an "Alternate  Payee")  of an  individual  who  is
granted an option to an interest  in such option relating to  marital
property rights or support obligations and (2) that the administrator
of the  Plan  determines would  be  a "qualified  domestic  relations
order," as that  term is defined  in section 414(p)  of the Code  and
section  206(d)  of  the  Employee  Retirement  Income  Security  Act
("ERISA"), but for the fact that the Plan is not a plan described  in
section 3(3) of ERISA.

    12.  AMENDMENT OF THE PLAN.
         (a)  The Board  at any  time, and  from time  to time,  may
amend the Plan.  However, except as provided in paragraph 10 relating
to adjustments upon changes in the  Common Stock, no amendment  shall
be effective  unless  approved by  the  stockholders of  the  Company
within twelve  (12)  months  before or  after  the  adoption  of  the
amendment, where the amendment will:
              (i)   Increase  the  number  of  shares  reserved  for
options under the Plan;
              (ii)  Modify  the requirements  as to  eligibility for
participation in the Plan (to  the extent such modification  requires
stockholder  approval  in   order  for  the   Plan  to  satisfy   the
requirements of Section  422(b) of  the Code  or to  comply with  the
requirements of Rule 16b-3 promulgated under the Exchange Act); or
              (iii) Modify  the  Plan  in  any  other  way  if  such
modification requires stockholder approval in  order for the Plan  to
satisfy the requirements of Section 422(b)  of the Code or to  comply
with the requirements  of Rule 16b-3  promulgated under the  Exchange
Act.
         (b)  It is expressly contemplated that the  Board may amend
the Plan in  any respect the  Board deems necessary  or advisable  to
provide optionees  with  the  maximum  benefits  provided  or  to  be
provided under  the  provisions  of  the  Code  and  the  regulations
promulgated thereunder relating to  employee incentive stock  options
and/or to  bring  the  Plan and/or  options  granted  under  it  into
compliance therewith.
         (c)  Rights and obligations under any option granted before
amendment of  the  Plan shall  not  be  altered or  impaired  by  any
amendment of the Plan, unless:  (i) the Company requests the consent

of the person to whom the option was granted; and (ii) such person
consents in writing.

    13.  TERMINATION OR SUSPENSION OF THE PLAN.
         (a)  The Board may  suspend or  terminate the  Plan at  any
time.  Unless sooner  terminated, the Plan  shall terminate on  March
14, 1998.  No options may be granted under the Plan while the Plan is
suspended or after it is terminated.
         (b)  Rights and obligations under any option  granted while
the Plan is in effect shall not be altered or impaired by  suspension
or termination of the Plan, except with the consent of the person  to
whom the option was granted.

    14.  EFFECTIVE DATE OF PLAN.
         The Plan shall become effective as determined by the Board.
No option granted  as the result  of the amendment  on April 2,  1991
shall be exercisable unless and until  said amendment is approved  by
the stockholders  of  the Company,  and  to the  extent  required  or
necessary under  applicable law,  amendments made  on April  2,  1991
shall not  be effective  until approved  by the  stockholders of  the
Company.
