        NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

                         September 30, 1996


1.   Summary of significant accounting policies

  Business


     Amgen Inc. ("Amgen" or the "Company") is a global  biotechnology
company that develops,  manufactures and  markets human  therapeutics
based on advanced cellular and molecular biology.

  Principles of consolidation

     The condensed  consolidated  financial  statements  include  the
accounts of the Company and its wholly owned subsidiaries as well  as
affiliated  companies  for  which  the  Company  has  a   controlling
financial  interest  and  exercises  control  over  their  operations
("majority  controlled  affiliates").    All  material   intercompany
transactions and  balances  have been  eliminated  in  consolidation.
Investments in affiliated companies which are  50% or less owned  and
where the Company exercises significant influence over operations are
accounted for using the equity method.  All other equity  investments
are accounted  for under  the  cost method.    The caption  "Loss  of
affiliates, net" includes Amgen's equity in the operating results  of
affiliated companies and  the minority  interest others  hold in  the
operating results of Amgen's majority controlled affiliates.

  Inventories

     Inventories are stated at the lower of cost or market.  Cost  is
determined in  a manner  which approximates  the first-in,  first-out
(FIFO) method.  Inventories are shown net of applicable reserves  and
allowances.  Inventories consist of the following (in millions):

     Quarterly NEUPOGEN(R)  sales  volume  in the  United  States  is
influenced by  a  number  of  factors  including  underlying  demand,
     
                                 8
<PAGE>
seasonal  changes   in   cancer  chemotherapy   administration,   and
wholesaler inventory  management  practices.    Wholesaler  inventory
reductions have tended  to reduce domestic  NEUPOGEN(R) sales in  the
first quarter of each year.

     The Company has  the exclusive right  to sell  Epoetin alfa  for
dialysis, diagnostics and  all non-human uses  in the United  States.
The Company sells Epoetin alfa under the brand name EPOGEN(R).  Amgen
has granted  to Ortho  Pharmaceutical  Corporation, a  subsidiary  of
Johnson &  Johnson  ("Johnson  & Johnson"),  a  license  relating  to
Epoetin alfa for sales in the United States for all human uses except
dialysis and diagnostics.  Pursuant to  this license, Amgen does  not
recognize product sales it makes into the exclusive market of Johnson
& Johnson and  does recognize  the product  sales made  by Johnson  &
Johnson into  Amgen's exclusive  market.   These sales  amounts,  and
adjustments thereto, are derived  from third-party data on  shipments
to end users and their usage (see Note 4, "Contingencies - Johnson  &
Johnson arbitrations").

  Income taxes

     Income taxes are accounted for  in accordance with Statement  of
Financial Accounting Standards ("SFAS") No. 109 (Note 3).

  Stock option and purchase plans

     The Company's stock options and purchase plans are accounted for
under Accounting  Principles Board  Opinion No.  25, "Accounting  for
Stock Issued to Employees".

  Earnings per share

     Earnings per share are computed in accordance with the  treasury
stock method.  Primary and fully diluted earnings per share are based
upon the weighted average number of common shares and dilutive common
stock equivalents during the period  in which they were  outstanding.
Common stock equivalents are outstanding options under the  Company's
stock option plans and put warrants on the Company's common stock.

  Use of estimates

     The preparation  of  financial  statements  in  conformity  with
generally accepted accounting principles requires management to  make
estimates and assumptions  that affect  the amounts  reported in  the
financial statements  and accompanying  notes.   Actual  results  may
differ from those estimates.

  Basis of presentation

     The financial information  for the three  and nine months  ended
September 30, 1996 and 1995 is unaudited but includes all adjustments
(consisting only  of normal  recurring  accruals) which  the  Company
considers necessary  for  a  fair  presentation  of  the  results  of
operations for these  periods.  Interim  results are not  necessarily
indicative of results for the full fiscal year.

     The Company has registered $200 million of unsecured medium term
debt securities ("Medium  Term Notes") of  which $109.0 million  were
outstanding at  September 30,  1996.   These Medium  Term Notes  bear
interest at fixed  rates averaging 5.8%  and mature in  one to  seven
years.

3.   Income taxes

4.   Contingencies

  Johnson & Johnson arbitrations

     In September 1985,  the  Company  granted Johnson  &  Johnson  a
license relating to certain patented  technology and know-how of  the
Company to sell  a genetically engineered  form of recombinant  human
erythropoietin, called Epoetin alfa, throughout the United States for
all human uses except  dialysis and diagnostics.   Johnson &  Johnson
sells Epoetin alfa under the brand name PROCRIT(R).

     A number of  disputes have arisen  between Amgen  and Johnson  &
Johnson as  to  their respective  rights  and obligations  under  the
various agreements between them, including the agreement granting the
license (the  "License Agreement").   These  disputes have  been  the
subject of arbitration  proceedings before  Judicial Arbitration  and
Mediation Services, Inc. in  Chicago, Illinois commencing in  January
1989.  A dispute that has not yet been resolved and is the subject of
the current arbitration proceeding  relates to the audit  methodology
currently employed  by  the Company  for  Epoetin alfa  sales.    The
Company and Johnson & Johnson are  required to compensate each  other
for Epoetin  alfa  sales which  either  party makes  into  the  other
party's exclusive  market.    The  Company  has  established  and  is
employing an audit  methodology to assign  the proceeds  of sales  of
EPOGEN(R)  and  PROCRIT(R)  in   Amgen's  and  Johnson  &   Johnson's
respective exclusive markets.  Based upon this audit methodology, the
Company is seeking  payment of approximately  $15 million  (excluding
interest) from Johnson &  Johnson for the  period 1991 through  1994.
Johnson & Johnson has disputed this  methodology and is proposing  an
alternative methodology for  adoption by the  arbitrator pursuant  to
which it is seeking payment of approximately $450 million  (including
interest through June 1996) for the period 1989 through 1994.  If, as
a result of the arbitration proceeding, a methodology different  from
that currently employed by  the Company is  instituted to assign  the
proceeds of sales between the parties, it may yield results that  are
different  from  the  results  of  the  audit  methodology  currently
employed by  the Company.   As  a result  of the  arbitration, it  is
possible that  the  Company  would recognize  a  different  level  of
EPOGEN(R) sales than are currently being recognized.  As a result  of
the arbitration,  the  Company  may be  required  to  pay  additional
compensation to Johnson & Johnson for sales during prior periods,  or
Johnson & Johnson may be required to pay compensation to the  Company
for such  prior period  sales.   While it  is impossible  to  predict
accurately or  determine  the  outcome of  these  proceedings,  based
primarily upon  the  merits of  its  claims and  based  upon  certain
liabilities established  due  to  the  inherent  uncertainty  of  any
arbitrated result, the  Company believes  that the  outcome of  these
proceedings will not have a material adverse effect on its  financial
statements.   A trial  commenced in  March 1996 regarding  the  audit
methodologies and compensation  for sales by  Johnson & Johnson  into
Amgen's exclusive market and sales by Amgen into Johnson &  Johnson's
exclusive market.

     The Company has filed a demand  in the arbitration to  terminate
Johnson & Johnson's rights under the License Agreement and to recover
damages for  breach of  the License  Agreement.   A hearing  on  this

                                 11  
<PAGE>
demand will  be scheduled  following the  adjudication of  the  audit
methodologies for  Epoetin alfa  sales.   On  October 27,  1995,  the
Company filed  a  complaint in  the  Circuit Court  of  Cook  County,
Illinois, which is now  pending in the  United States District  Court
for the Northern  District of Illinois,  seeking an order  compelling
Johnson & Johnson  to arbitrate the  Company's claim for  termination
before the arbitrator.  The Company is unable to predict at this time
the outcome  of  the  demand  for termination  or  when  it  will  be
resolved.

     On October 2, 1995,  Johnson  & Johnson  filed  a demand  for  a
separate  arbitration  proceeding  against  the  Company  before  the
American  Arbitration  Association  ("AAA")  in  Chicago,   Illinois.
Johnson &  Johnson  alleges  in this  demand  that  the  Company  has
breached the License Agreement.  The demand also includes allegations
of various antitrust violations.  In  this demand, Johnson &  Johnson
seeks an  injunction,  declaratory relief,  unspecified  compensatory
damages, punitive damages and costs.  The Company has filed a  motion
to  stay  the  arbitration  pending  the  outcome  of  the   existing
arbitration proceedings  before  Judicial Arbitration  and  Mediation
Services, Inc. discussed above.  The Company has also filed an answer
and counterclaim denying that AAA has jurisdiction to hear or  decide
the claims  stated in  the demand,  denying  the allegations  in  the
demand and counterclaiming for certain unpaid invoices.

  Synergen ANTRIL(TM) litigation

     Several lawsuits have  been filed against  the Company's  wholly
owned subsidiary,  Amgen  Boulder  Inc.  (formerly  Synergen,  Inc.),
alleging misrepresentations  in connection  with Synergen's  research
and development of ANTRIL(TM) for the treatment of sepsis.  One suit,
filed by a limited partner of a partnership with which Amgen  Boulder
Inc. is affiliated, has been certified as a class action.  That  suit
seeks rescission of certain payments made by the limited partners  to
the partnership (or  unspecified damages not  less than  $52 million)
and treble  damages based  on a  variety of  allegations relating  to
state and federal law claims.  The plaintiffs in that suit also  have
filed a  second  amended  complaint alleging  violations  of  federal
securities laws.  Two  broker-dealers who acted  as market makers  in
Synergen options have also  filed a suit claiming  in excess of  $3.2
million in trading losses.  On August 6, 1996, the District Court for
the State  of Colorado  dismissed without  prejudice for  failure  to
prosecute an  action  brought  by three  Synergen  stockholders  that
alleged   violations   of   state   securities   laws,   fraud    and
misrepresentation and sought  an unspecified  amount of  compensatory
damages and punitive damages.

     While it is not possible to predict accurately or determine  the
eventual outcome of  the Johnson &  Johnson arbitration  proceedings,
the Synergen litigation or various other legal proceedings (including
patent disputes)  involving  Amgen,  the Company  believes  that  the
outcome of these proceedings will not have a material adverse  effect
on its financial statements.

5.   Stockholders' equity

     During the nine  months ended  September 30,  1996, the  Company
repurchased 6.1 million shares of its common stock at a total cost of
$346.8 million under its common stock repurchase program.  The  Board
of Directors  has authorized  the Company  to repurchase  up to  $450
million of shares during 1996.   Stock repurchased under the  program
is retired.

     In connection with the  Company's stock repurchase program,  put
warrants were sold  to an independent  third party  during the  third
quarter of 1996.   Each put warrant entitles  the holder to sell  one
share of Amgen Inc. common stock to the Company at a specified price.
On September 30, 1996, 2.7 million put warrants were outstanding with
exercise prices ranging  from $52.00 to  $58.80 per share.   The  put
warrants are exercisable only at maturity and expire at various dates
between April 1997 and  August 1997.  In  the event the put  warrants
are exercised, the Company  may elect to pay  the holder in cash  the
difference between the  exercise price and  the market  price of  the
Company's shares, in  lieu of repurchasing  the stock.   The  maximum
potential  repurchase   obligation  of   $157.4  million   has   been
reclassified  from  stockholders'  equity  to  put  warrants  as   of
September 30,  1996.   In  the event  that  the put  warrants  expire
unexercised, the  liability  associated  with  these  instruments  is
extinguished.

     Additionally, during  the third  quarter  of 1996,  the  Company
purchased call options from  an independent third  party.  Each  call
option entitles the  Company to buy  one share of  Amgen Inc.  common
stock at a specified price.  At September 30, 1996, 1.3 million  call
options were outstanding, with exercise prices ranging from $58.00 to
$61.90 per share.  The call options are exercisable only at  maturity
and expire at various dates between  April 1997 and August 1997.   In
the event the call  options are exercised, the  Company may elect  to
receive cash for the  difference between the  exercise price and  the
market price of  the Company's shares,  in lieu  of repurchasing  the
stock.   The premiums  received from  the sale  of the  put  warrants
offset in full the cost of the call options.


Item 2.   Management's Discussion and Analysis of Financial Condition
          and Results of Operations


Liquidity and Capital Resources

     Cash provided by operating activities  has been and is  expected
to continue to be the Company's primary source of funds.  During  the
nine months  ended September  30,  1996, operations  provided  $545.8
million of cash compared with $548.2  million during the same  period
last year.   The Company had  cash, cash  equivalents and  marketable
securities of $994.1  million at  September 30,  1996, compared  with
$1,050.3 million at December 31, 1995.

     Capital expenditures totaled $167.6 million for the nine  months
ended September 30, 1996, compared with  $106.8 million for the  same
period a year ago.  Over the  next few years, the Company expects  to

                               13
<PAGE>
spend approximately $200 million to $300 million per year on  capital
projects and equipment to expand the Company's global operations.

     In April 1996, the Company invested  $48 million in a  corporate
partner, Regeneron Pharmaceuticals,  Inc., and  acquired 3.0  million
shares of common stock along with warrants to purchase an  additional
0.7 million shares.

     The Company receives  cash from the  exercise of employee  stock
options.   During the  nine months  ended September  30, 1996,  stock
options and their related tax benefits provided $98.3 million of cash
compared with $108.2 million for the period last year.  Proceeds from
the exercise of  stock options and  their related  tax benefits  will
vary  from  period  to  period  based  upon,  among  other   factors,
fluctuations in the market value of  the Company's stock relative  to
the exercise price of such options.

     The Company  has  a  stock  repurchase  program  to  offset  the
dilutive effect  of  its  employee benefit  stock  option  and  stock
purchase plans.  During the nine months ended September 30, 1996, the
Company purchased 6.1 million shares of its common stock at a cost of
$346.8 million compared with 5.6 million  shares purchased at a  cost
of $199.9 million  during the  same period  last year.   The  Company
expects to repurchase $400 million to $450 million of its stock under
the program  in 1996.   To  partially  hedge the  cost of  its  stock
repurchase program,  the Company  issued put  warrants and  purchased
call options  in the  third quarter  of  1996.   See  Note 5  to  the
Condensed Consolidated Financial Statements.

     To provide for  financial flexibility  and increased  liquidity,
the Company has established several sources  of debt financing.   The
Company has a  shelf registration under  which it could  issue up  to
$200 million of  Medium Term Notes.   At September  30, 1996,  $109.0
million of Medium Term Notes were outstanding which mature in one  to
seven years.    The Company  has  a commercial  paper  program  which
provides for short-term borrowings up to an aggregate face amount  of
$200 million.    As  of  September  30,  1996,  the  Company  had  no
outstanding commercial paper.   The Company also  has a $150  million
revolving line of credit.  No borrowings on this line of credit  were
outstanding at September 30, 1996.

     The Company invests its  cash in accordance  with a policy  that
seeks to maximize returns while  ensuring both liquidity and  minimal
risk of principal  loss.  The  policy limits  investments to  certain
types of  instruments issued  by institutions  with investment  grade
credit  ratings,   and   places  restrictions   on   maturities   and
concentration by  type and  issuer.   The majority  of the  Company's
portfolio is composed of fixed  income investments which are  subject
to the risk  of market  interest rate  fluctuations, and  all of  the
Company's investments  are  subject  to  risks  associated  with  the
ability of  the  issuers  to  perform  their  obligations  under  the
instruments.

     The Company  has a  program to  manage certain  portions of  its
exposure to fluctuations in  foreign currency exchange rates  arising
from international  operations.   The  Company generally  hedges  the

                              14
<PAGE>
receivables and  payables with  foreign currency  forward  contracts,
which typically mature within six months.   The Company uses  foreign
currency option and forward  contracts which generally expire  within
12 months to hedge certain anticipated future sales and expenses.  At
September 30, 1996, outstanding option and forward contracts  totaled
$7.5 million and $60.2 million, respectively.

     The Company believes  that existing funds,  cash generated  from
operations, and existing  sources of debt  financing are adequate  to
fund its working capital and capital expenditure requirements for the
foreseeable future,  as  well  as to  support  its  stock  repurchase
program.  However, the Company may raise additional capital from time
to time to take advantage of  favorable conditions in the markets  or
in connection with the Company's corporate development activities.


Results of Operations

  Product sales

     Product sales increased 15.8% and 14.6%  for the three and  nine
months ended September 30, 1996, respectively, compared with the same
periods last year.

     NEUPOGEN(R) (Filgrastim)

     Worldwide   NEUPOGEN(R)   sales   were   $258.8   million    and
$746.3 million for  the three  and nine  months ended  September  30,
1996, respectively.  These amounts  represent increases of 12.4%  and
8.2%, respectively, over the same periods last year.

     Domestic sales  of NEUPOGEN(R)  were $186.8  million and  $533.7
million for  the three  and nine  months  ended September  30,  1996,
respectively.  These amounts represent increases of $23.1 million and
$46.9 million, or 14.1% and 9.6%, respectively, over the same periods
last year.  The increases are primarily due to growth in demand and a
price increase which was in line  with the Consumer Price Index.   In
1995, wholesalers accelerated their purchasing because of the  timing
of the July  4 holiday.   As a  result, approximately  $7 million  of
sales were shifted  from the third  quarter of 1995  into the  second
quarter of  1995.   Such accelerated  wholesaler purchasing  did  not
occur in 1996.

     Quarterly NEUPOGEN(R)  sales  volume  in the  United  States  is
influenced by  a  number  of  factors  including  underlying  demand,
seasonal change in cancer chemotherapy administration, and wholesaler
inventory management practices.  Wholesaler inventory reductions have
tended to reduce domestic NEUPOGEN(R) sales  in the first quarter  of
each year.

     The ongoing and intensifying  cost containment pressures in  the
health care marketplace, including use of guidelines in patient care,
have contributed to  the slowing  of growth  in domestic  NEUPOGEN(R)
usage over the past several years.   These pressures are expected  to
continue to influence such growth for the foreseeable future.

                            15
<PAGE>
     International sales of  NEUPOGEN(R), primarily  in Europe,  were
$72.0 million and $212.6 million for the three and nine months  ended
September 30, 1996, respectively.  These amounts represent  increases
of $5.4 million and $9.8 million, or 8.1% and 4.8% respectively, over
the same periods last year.   Unit demand accounted for most of  this
increase but demand benefited in part from the timing of shipments to
certain end  users.   The impact  of  foreign currency  was  slightly
negative.

     The Company's  overall share  of the  colony stimulating  factor
market in the European Union ("EU")  has continued to decrease  since
the  introduction  in   1994  of  a   competing  granulocyte   colony
stimulating  factor  product.    The  Company  does  not  expect  the
competitive intensity to subside  in the near  future.  In  addition,
increasing government cost control measures have slowed the growth of
the colony stimulating factor market in the EU.

     EPOGEN(R) (Epoetin alfa)

     EPOGEN(R) sales were $274.5 million  and $782.8 million for  the
three and nine months  ended September 30,  1996, respectively.   The
amounts represent increases  of $44.2 million  and $138.0 million  or
19.2% and  21.4%,  respectively, over  the  same periods  last  year.
These increases were  primarily due to  a continued  increase in  the
U.S. dialysis  patient population  and the  administration of  higher
doses.

     Increases in  both  the  U.S. dialysis  patient  population  and
dosing is expected to  continue to drive  EPOGEN(R) sales.   However,
the Company  believes that  as  more dialysis  patients'  hematocrits
reach target levels, dosing increases will diminish.

  Corporate partner revenues

     Corporate partner revenues decreased  $0.7 million, or 2.9%  and
increased $21.8 million, or  33.5% during the  three and nine  months
ended September 30, 1996, respectively, compared with the same periods
last year.   The nine month  period increase was  primarily due to  a
$15 million payment received from Yamanouchi Pharmaceutical Co., Ltd.
under a licensing agreement  in June 1996.   In connection with  this
agreement,  the  Company   has  licensed  the   rights  to   develop,
manufacture and  commercialize  the Company's  proprietary  Consensus
Interferon in specified geographic areas of  the world.  The  Company
will receive  milestone  payments  as well  as  royalties  on  future
product sales.

  Cost of sales

     Cost of sales  as a percentage  of product sales  was 13.7%  and
13.6% for  the  three  and nine  months  ended  September  30,  1996,
respectively, compared with 13.9% and 15.5% for the same periods last
year. These  improvements  reflect efficiencies  from  the  fill-and-
finish  facility  in  Puerto  Rico.     As  a  result  of   continued
efficiencies in Puerto Rico in 1996, cost of sales as a percentage of
product sales is expected to range from 13%-14%.

                              16  
<PAGE>
  Research and development

     During the  three  and nine  months  ended September  30,  1996,
research  and  development  expenses  increased  $24.9  million   and
$56.9 million, or 23.6%  and 17.4%, respectively,  compared with  the
same periods last year.  These increases were primarily due to staff-
related expenses  and external  costs  for clinical  and  preclinical
activities necessary  to  support  the  ongoing  product  development
activities.  Annual research and development expenses are expected to
increase at a rate exceeding the Company's product sales growth  rate
due to  planned  increases  in internal  efforts  on  development  of
product candidates and discovery.

  Marketing and selling

     Marketing  and  selling  expenses  increased  $7.3  million  and
$24.7 million, or 10.6% and 12.5%, respectively, during the three and
nine months ended September 30, 1996  compared with the same  periods
last  year.    These  increases  primarily  reflect  market  research
activities and efforts to increase  the number of patients  receiving
NEUPOGEN(R) and to bring more patients receiving EPOGEN(R) within the
target hematocrit range.   In  1996, marketing  and selling  expenses
combined with  general and  administrative expenses  are expected  to
have an  aggregate  annual growth  rate  lower than  the  anticipated
annual product sales growth rate.

  General and administrative

     General and administrative expenses  increased $4.5 million  and
$12.3 million, or 12.0% and 11.5%, respectively, during the three and
nine months ended September 30, 1996  compared with the same  periods
last year.   These  increases were  primarily  due to  higher  staff-
related expenses.    In  1996, general  and  administrative  expenses
combined with marketing and selling expenses are expected to have  an
aggregate annual  growth  rate  lower  than  the  anticipated  annual
product sales growth rate.

  Interest and other income

     Interest  and   other   income  increased   $1.4   million   and
$1.3 million, or 9.1%  and 2.8%, respectively,  during the three  and
nine months ended September 30, 1996  compared with the same  periods
last year.   These increases resulted  from fluctuations in  interest
rates and  cash balances  compared with the same period a  year  ago.
Interest and other income is expected to continue to vary from period
to period  primarily  due to  changes  in cash  balances,  timing  of
capital gains/losses, and fluctuations in interest rates.

  Income taxes

     The Company's effective tax rate for  the three and nine  months
ended September 30, 1996 was 28.0% and 29.8% compared with 31.7%  and
32.5%, respectively, for the same periods last year.  The decrease in
the current tax rate is primarily due to a favorable ruling  received
from the Puerto  Rican government.   However, the federal  government
also enacted legislation during the current quarter which,  beginning

                             17
<PAGE>
in 1998, limits  the tax  benefits it  grants that  relate to  Puerto
Rican operations.  The Company's effective tax rate will rise in 1998
due to this legislation.

Financial Outlook

     Worldwide NEUPOGEN(R) sales for 1996 are  expected to grow at  a
rate lower  than the  1995 growth  rate.   Future  NEUPOGEN(R)  sales
increases  are  dependent  primarily  upon  further  penetration   of
existing markets, the timing and nature of additional indications for
which the  product may  be approved  and the  effects of  competitive
products.  NEUPOGEN(R) usage is expected  to continue to be  affected
by cost containment pressures on health care providers worldwide.  In
addition, international NEUPOGEN(R) sales will continue to be subject
to competition, government cost containment measures, and changes  in
foreign currency exchange rates.

     EPOGEN(R) sales for  1996 are also  expected to grow  at a  rate
lower than  the  1995 growth  rate.   The  Company  anticipates  that
increases in both  the U.S.  dialysis patient  population and  dosing
will continue to drive EPOGEN(R) sales.  The Company believes that as
more  dialysis  patients'  hematocrits   reach  target  levels,   the
contribution of dosing  to sales increases  will diminish.   Patients
receiving treatment for end stage renal disease are covered primarily
under  medical   programs  provided   by  the   federal   government.
Therefore, EPOGEN(R) sales may also be affected by future changes  in
reimbursement rates or  the basis  for reimbursement  by the  federal
government.

     The Company anticipates  that total product  sales and  earnings
will grow at double digit rates  in 1996, but these growth rates  are
expected to be  lower than 1995  growth rates.   Estimates of  future
product sales and earnings,  however, are necessarily speculative  in
nature and are difficult to predict with accuracy.

     Except for  the  historical information  contained  herein,  the
matters discussed herein  are by their  nature forward-looking.   For
reasons stated, or for various unanticipated reasons, actual  results
may  differ  materially.    Amgen  operates  in  a  rapidly  changing
environment that involves a number of risks, some of which are beyond
the Company's control.   Future operating  results and matters  which
may affect the Company's stock price  may be affected by a number  of
factors, certain  of which  are discussed  elsewhere herein  and  are
discussed in the sections  appearing under the heading  "Management's
Discussion  and  Analysis  of  Financial  Condition  and  Results  of
Operations--Factors That May Affect Future Results" in the  Company's
Quarterly Report on Form 10-Q for  the quarter ended March 31,  1996,
which  sections  are  incorporated  herein  by  reference  and  filed
herewith.

Legal Matters

     The Company is  engaged in arbitration  proceedings with one  of
its licensees  and various  legal proceedings  relating to  Synergen.
For a  discussion  of these  matters  see  Note 4  to  the  Condensed
Consolidated Financial Statements.

                     PART II - OTHER INFORMATION

Item 1.   Legal Proceedings

     The Company is  engaged in arbitration  proceedings with one  of
its licensees.  For a complete discussion of these matters see Note 4
to the Condensed Consolidated Financial Statements - "Contingencies -
Johnson & Johnson  arbitrations."  Other  legal proceedings are  also
reported in Note 4 to the Condensed Consolidated Financial Statements
and in the Company's Form 10-K for the year ended December 31,  1995,
with material  developments  or  new proceedings  since  that  report
described in the Company's Form 10-Q for the quarters ended March 31,
1996 and  June 30,  1996 and  below.   While it  is not  possible  to
predict accurately  or to  determine the  eventual outcome  of  these
matters, the  Company  believes  that  the  outcome  of  these  legal
proceedings will not have a material adverse effect on the  financial
statements of the Company.

  Synergen ANTRIL(TM) litigation

     Several lawsuits have  been filed against  the Company's  wholly
owned subsidiary,  Amgen  Boulder  Inc.  (formerly  Synergen,  Inc.),
alleging misrepresentations  in connection  with Synergen's  research
and development  of ANTRIL  (TM) for  the treatment  of sepsis.    On
August 6, 1996,  the  District  Court  for  the  State  of   Colorado
dismissed one of these lawsuits without  prejudice  for  failure  to
prosecute  an  action brought by  three Synergen  stockholders that  
alleged violations  of state securities  laws, fraud  and  
misrepresentation and  sought  an unspecified amount to compensatory 
damages and punitive damages.

  Genentech Litigation

     On October 16, 1996,  Genentech, Inc. filed  suit in the  United
States District Court for the Northern District of California seeking
an unspecified  amount of  compensatory damages,  treble damages  and
injunctive relief  on  its  U.S.  Patents  4,704,362,  5,221,619  and
4,342,832 relating to  vectors for  expressing cloned  genes and  the
methods for such expression.  Genentech, Inc. alleges that Amgen  has
infringed its patents by manufacturing  and selling NEUPOGEN(R).   As
of October 31, 1996, Amgen had not been served with this lawsuit.


Item 6.   Exhibits and Reports on Form 8-K

     (a)  Reference is made to the Index to Exhibits included herein.

     (b)  No reports on Form 8-K were  filed during the three  months
          ended September 30, 1996.

                               EXHIBIT

                             AMGEN INC.

           AMENDED AND RESTATED 1991 EQUITY INCENTIVE PLAN


    1.   PURPOSE.

         (a)  The purpose of the Amended and Restated 1991 Equity
Incentive Plan (the "Plan") is to provide a means by which employees
or directors 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 created for the benefit of
their families, may be given an opportunity to benefit from increases
in value of the stock of the Company through the granting of (i)
incentive stock options, (ii) nonqualified stock options, (iii) stock
bonuses, and (iv) rights to purchase restricted stock, all as defined
below.

         (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 employed by or serving as directors or
consultants to the Company, 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 rights issued under the
Plan ("Stock Awards") 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 (i) stock options granted
pursuant to paragraph 5 hereof, including 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") (together hereinafter referred to as
"Options"), or (ii) stock bonuses or rights to purchase restricted
stock granted pursuant to paragraph 6 hereof.

         (e)  The word "Trust" as used in the Plan shall mean a
trust created for the benefit of the employee, director 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, director 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).
                              
                                   1
<PAGE>
         (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 Stock Awards; when
and how Stock Awards shall be granted; whether a Stock Award will be
an Incentive Stock Option, a Nonqualified Stock Option, a stock
bonus, a right to purchase restricted stock, or a combination of the
foregoing; the provisions of each Stock Award granted (which need not
be identical), including the time or times when a person shall be
permitted to purchase or receive stock pursuant to a Stock Award; and
the number of shares with respect to which Stock Awards shall be
granted to each such person.

              (2)  To construe and interpret the Plan and Stock
Awards 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 Stock Award, 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 13.

              (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 two (2) members of the Board
(the "Committee").  One or more of these members may be non-employee
directors and outside directors, if required and as defined by the
provisions of subparagraphs 2(d) and 2(e).  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.  Notwithstanding anything else in this subparagraph
2(c) to the contrary, at any time the Board or the Committee may
delegate to a committee of one or more members of the Board the
authority to grant or amend options to all employees, directors or
consultants or any portion or class thereof.

         (d)  The term "non-employee director" shall mean a member
of the Board who (i) is not currently an officer of the Company or a
parent or subsidiary of the Company (as defined in Rule 16a-1(f)
promulgated by the Securities and Exchange Commission under Section
16 of the Securities Exchange Act of 1934, as amended (the "Exchange
Act")) or an employee of the Company or a parent or subsidiary of the
Company; (ii) does not receive compensation from the Company or a
parent or subsidiary of the Company for services rendered in any
capacity other than as a member of the Board (including a consultant)
in an amount required to be disclosed to the Company's stockholders
under Rule 404 of Regulation S-K promulgated by the Securities and
Exchange Commission ("Rule 404"); (iii) does not possess an interest

                               2      
<PAGE>
in any other transaction required to be disclosed under Rule 404; or
(iv) is not engaged in a business relationship required to be
disclosed under Rule 404, as all of these provisions are interpreted
by the Securities and Exchange Commission under Rule 16b-3
promulgated under the Exchange Act.

         (e)  The term "outside director," 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), who is
considered to be an "outside director" in accordance with the rules,
regulations or interpretations of Section 162(m) of the Code.

         (f)  Any requirement that an administrator of the Plan be a
"non-employee director" or "outside director" 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 11 relating to
adjustments upon changes in stock, the stock that may be issued
pursuant to Stock Awards granted under the Plan shall not exceed in
the aggregate Forty Eight Million (48,000,000) shares of the
Company's $.0001 par value common stock (the "Common Stock").  If any
Stock Award 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 Stock Award shall again become
available for the Plan.  Shares repurchased by the Company pursuant
to any repurchase rights reserved by the Company pursuant to the Plan
shall not be available for subsequent issuance under 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 at the time the Incentive Stock Option is granted)
of the Common Stock with respect to which incentive stock options (as
defined by the Code) 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).  If it is determined that an entire Option or any portion
thereof does not qualify for treatment as an Incentive Stock Option
by reason of exceeding such maximum, such Option or the applicable
portion shall be considered a Nonqualified Stock Option.

    4.   ELIGIBILITY.

         (a)  Incentive Stock Options may be granted only to
employees (including officers) of the Company or its Affiliates.  A
director of the Company shall not be eligible to receive Incentive
Stock Options unless such director is also an employee of the Company
or any Affiliate.  Stock Awards other than Incentive Stock Options
may be granted to employees (including officers) or directors of or
consultants to the Company or any Affiliate or to Trusts of any such

                                3
<PAGE>
employee, director 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 Stock Awards may be granted, or in the determination of the
number of shares which may be covered by Stock Awards granted to a
director, the Plan 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.
Notwithstanding the foregoing, the restrictions set forth in this
subparagraph 4(b) shall not apply if the Board or Committee expressly
declares that such restrictions shall not apply.

         (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
Incentive Stock Option is not exercisable after the expiration of
five (5) years from the date of grant.

         (d)  Stock Awards shall be limited to a maximum of 500,000
shares of Common Stock per person per calendar year, which reflects
the Company's two for one stock split in August 1995.

    5.   TERMS OF STOCK OPTIONS.

         Each Option shall be in such 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 and
each Nonqualified 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.

         (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 shares of Common Stock of the Company

                                4
<PAGE>
that have been held for the period required to avoid a charge to the
Company's reported earnings and valued at the fair market value on
the date of exercise, (B) according to a deferred payment or other
arrangement 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; including but not limited
to payment of the purchase price pursuant to a program developed
under Regulation T as promulgated by the Federal Reserve Board which
results in the receipt of cash (or a check) by the Company before
Common Stock is issued or the receipt of irrevocable instruction to
pay the aggregate exercise price of the Company from the sales
proceeds before Common Stock is issued.

    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 become exercisable
("vest") with respect to some or all of the shares allotted to that
period, and may be exercised with respect to some or all of the
shares allotted to such period and/or 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: (i) to give written assurances

                                 5
<PAGE>
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 (ii) 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: (x) 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 (y) 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 or director 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 or director; (ii) the
optionee dies while in the employ of or while serving as a consultant
or director to the Company or an Affiliate, or within not more than
three (3) months after termination of such employment or relationship
as a consultant or director, 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 term 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 director with the Company or an
Affiliate; or (B) that it may be exercised more than three (3) months
after termination of the optionee's employment or relationship as a
consultant or director 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 or director.

         (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 or director 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 dates
of 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.

                                 6
<PAGE>
         (i)  To the extent provided by the terms of an Option, each
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: (i) tendering a
cash payment; (ii) authorizing the Company to withhold from the
shares of the Common Stock otherwise issuable to the optionee as a
result of the exercise of the Option a number of shares having a fair
market value less than or equal to the amount of the withholding tax
obligation; or (iii) 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 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; (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; and (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.

    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, 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) and shall be subject to
such other terms and conditions as the Board or Committee may
determine.

    6.   TERMS OF STOCK BONUSES AND PURCHASES OF
         RESTRICTED STOCK.

         Each stock bonus or restricted stock purchase agreement
shall be in such form and shall contain such terms and conditions as
the Board or the Committee shall deem appropriate.  The terms and
conditions of stock bonus or restricted stock purchase agreements may
change from time to time, and the terms and conditions of separate

                                7
<PAGE>
agreements need not be identical, but each stock bonus or restricted
stock purchase agreement shall include (through incorporation of
provisions hereof by reference in the agreement or otherwise) the
substance of each of the following provisions as appropriate:

         (a)  The purchase price under each stock purchase agreement
shall be such amount as the Board or Committee shall determine and
designate in such agreement.  Notwithstanding the foregoing, the
Board or the Committee may determine that eligible participants in
the Plan may be awarded stock pursuant to a stock bonus agreement in
consideration for past services actually rendered to the Company or
for its benefit.

         (b)  No rights under a stock bonus or restricted stock
purchase agreement shall be assignable by any participant under the
Plan, either voluntarily or by operation of law, except where such
assignment is required by law or expressly authorized by the terms of
the applicable stock bonus or restricted stock purchase agreement.

         (c)  The purchase price of stock acquired pursuant to a
stock purchase agreement shall be paid either:  (i) in cash at the
time of purchase; (ii) at the discretion of the Board or the
Committee, according to a deferred payment or other arrangement with
the person to whom the Common Stock is sold; or (iii) in any other
form of legal consideration that may be acceptable to the Board or
the Committee in their discretion; including but not limited to
payment of the purchase price pursuant to a program developed under
Regulation T as promulgated by the Federal Reserve Board which
results in the receipt of cash (or a check) by the Company before
Common Stock is issued or the receipt of irrevocable instruction to
pay the aggregate exercise price of the Company from the sales
proceeds before Common Stock is issued.  Notwithstanding the
foregoing, the Board or the Committee to which administration of the
Plan has been delegated may award Common Stock pursuant to a stock
bonus agreement in consideration for past services actually rendered
to the Company or for its benefit.

         (d)  Shares of Common Stock sold or awarded under the Plan
may, but need not, be subject to a repurchase option in favor of the
Company in accordance with a vesting schedule to be determined by the
Board or the Committee.

         (e)  In the event a person ceases to be an employee of or
ceases to serve as a director or consultant to the Company or an
Affiliate, the Company may repurchase or otherwise reacquire any or
all of the shares of Common Stock held by that person which have not
vested as of the date of termination under the terms of the stock
bonus or restricted stock purchase agreement between the Company and
such person.

    7.   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

                                 8
<PAGE>
affected holders of Options, (i) the repricing of any outstanding
Options under the Plan and/or (ii) the cancellation of any
outstanding Options under the Plan and the grant in substitution
therefor of new Options under the Plan covering the same or different
numbers of shares of Common Stock, but having an exercise price per
share not less than one hundred percent (100%) of the fair market
value per share of Common Stock on the new grant date 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.

    8.   COVENANTS OF THE COMPANY.

         (a)  During the terms of the Stock Awards granted under the
Plan, the Company shall keep available at all times the number of
shares of Common Stock required to satisfy such Stock Awards up to
the number of shares of Common Stock authorized under the Plan.

         (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 Common Stock under the
Stock Awards granted under the Plan; provided, however, that this
undertaking shall not require the Company to register under the
Securities Act either the Plan, any Stock Award granted under the
Plan or any Common Stock issued or issuable pursuant to any such
Stock Award.  If, after reasonable efforts, the Company is unable to
obtain from any such regulatory commission or agency the authority
that counsel for the Company deems necessary for the lawful issuance
and sale of Common Stock under the Plan, the Company shall be
relieved from any liability for failure to issue and sell Common
Stock upon exercise of such Stock Awards unless and until such
authority is obtained.

    9.   USE OF PROCEEDS FROM COMMON STOCK.

         Proceeds from the sale of Common Stock pursuant to Stock
Awards granted under the Plan shall constitute general funds of the
Company.

    10.  MISCELLANEOUS.

          (a)  The Board or Committee shall have the power to
accelerate the time during which a Stock Award may be exercised or
the time during which a Stock Award or any part thereof will vest,
notwithstanding the provisions in the Stock Award 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's employment or a
director's or consultant's affiliation with the Company is terminated
by reason of death or disability (within the meaning of Title II or
XVI of the Social Security Act and as determined by the Social
Security Administration), the vesting schedule of Options granted to
such employee, director or consultant or to the Trusts of such
employee, director or consultant shall be accelerated by twelve
months for each

                                9
<PAGE>
full year the employee has been employed by or the director or
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 upon death provided for in
the preceding sentence of this paragraph 10(a) and Options granted
under the Plan that are outstanding on June 18, 1996, shall be
amended to include the accelerated vesting upon disability provided
for in the preceding sentence of this paragraph 10(a).

         (b)  Neither an optionee nor any person to whom an Option
is transferred under the provisions of the Plan 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)  Nothing in the Plan or any instrument executed or
Stock Award granted pursuant thereto shall confer upon any eligible
employee, consultant, director, optionee or holder of Stock Awards
under the Plan any right to continue in the employ of the Company or
any Affiliate or to continue acting as a consultant or director or
shall affect the right of the Company or any Affiliate to terminate
the employment or consulting relationship or directorship of any
eligible employee, consultant, director, optionee or holder of Stock
Awards under the Plan with or without cause.  In the event that a
holder of Stock Awards under the Plan 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 or director for purposes hereof, and (ii) suspend or
otherwise delay the time or times at which exercisability or vesting
would otherwise occur with respect to any outstanding Stock Awards
under the Plan.

    11.  ADJUSTMENTS UPON CHANGES IN COMMON STOCK.

         If any change is made in the Common Stock subject to the
Plan, or subject to any Stock Award 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 other transaction not involving the
receipt of consideration by the Company), the Plan and outstanding
Stock Awards will be appropriately adjusted in the class(es) and
maximum number of shares subject to the Plan, the maximum number of
shares which may be granted to a participant in a calendar year, and
the class(es) and number of shares and price per share of stock
subject to outstanding Stock Awards.  Such adjustment shall be made
by the Board or the Committee, the determination of which shall be
final, binding and conclusive.  (The conversion of any convertible
securities of the Company shall not be treated as a "transaction not
involving the receipt of consideration".)

                                  10

    12.  CHANGE OF CONTROL.

          (a)  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
Stock Awards become vested shall automatically be accelerated so that
the unvested portions of all Stock Awards 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 in Control.  Upon and following the acceleration of the
vesting and exercise periods, at the election of the holder of the
Stock Award, the Stock Award may be:  (x) exercised (with respect to
Options) or, if the surviving or acquiring corporation agrees to
assume the Stock Awards or substitute similar stock awards, (y)
assumed; or (z) replaced with substitute stock awards.  Options not
exercised, substituted or assumed prior to or upon the Change in
Control shall be terminated.

         (b)  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 of April 2,
1991, 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 April 2, 1991, 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

                                   11
<PAGE>
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.

    13.  QUALIFIED DOMESTIC RELATIONS ORDERS

          (a)  Anything in the Plan to the contrary notwithstanding,
rights under Stock Awards 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 a
Stock Award 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 a Stock Award 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 Stock Award shall be subject to the same vesting terms
and exercise period as if the Stock Award were still held by the
grantee, (2) an Alternate Payee may not transfer a Stock Award 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 a Stock Award, transfer of the
proceeds of the exercise of such Stock Award, 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 a Stock Award 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 a Stock Award to an interest in such Stock Award 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.

    14.  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 11 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:

                                  12
<PAGE>
              (i)  Increase the number of shares reserved for Stock
Awards 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

            (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.

         (b)  The Board may in its sole discretion submit any other
amendment to the Plan for stockholder approval, including, but not
limited to, amendments to the Plan intended to satisfy the
requirements of Section 162(m) of the Code and the regulations
promulgated thereunder regarding the exclusion of performance-based
compensation from the limit on corporate deductibility of
compensation to certain executive officers.

         (c)  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.

         (d)  Rights and obligations under any Stock Award granted
before amendment of the Plan shall not be impaired by any amendment
of the Plan, unless:  (i) the Company requests the consent of the
person to whom the Stock Award was granted; and (ii) such person
consents in writing.

    15.  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 December
31, 2000.  No Stock Awards may be granted under the Plan while the
Plan is suspended or after it is terminated.

         (b)  Rights and obligations under any Stock Awards granted
while the Plan is in effect shall not be impaired by suspension or
termination of the Plan, except with the consent of the person to
whom the Stock Award was granted.

    16.  EFFECTIVE DATE OF PLAN.

          The Plan shall become effective as determined by the Board.

                              EXHIBIT

                             AMGEN INC.

            AMENDED AND RESTATED 1984 STOCK OPTION PLAN


    1.   PURPOSE.

         (a)  The purpose of the Plan is to provide a means by
which selected employees, directors (if declared eligible under
paragraph 4) 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 with the Company, 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").  (Note:  Certain Nonqualified Stock
Options granted under prior versions of the Plan are labeled
"Nonincentive 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.

          (e)  The word "Trust" as used in the Plan shall mean a
trust created for the benefit of the employee, director 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, director or consultant for whose benefit the option
is granted to a Trust, as the context shall require.

                                1

    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 10.

              (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 two (2) members of the Board
(the "Committee").  One or more of these members may be a "Non-
Employee Director" (a director who (i) is not currently an officer
of the Company or a parent or subsidiary of the Company (as defined
in Rule 16a-1(f) promulgated by the Securities and Exchange
Commission under Section 16 of the Securities Exchange Act of 1934,
as amended (the "Exchange Act")) or an employee of the Company or a
parent or subsidiary of the Company; (ii) does not receive
compensation from the Company or a parent or subsidiary of the
Company for services rendered in any capacity other than as a member
of the Board (including a consultant) in an amount required to be
disclosed to the Company's stockholders under Rule 404 of Regulation
S-K promulgated by the Securities and Exchange Commission ("Rule
404"); (iii) does not possess an interest in any other transaction
required to be disclosed under Rule 404; or (iv) is not engaged in a
business relationship required to be disclosed under Rule 404, as
all of these provisions are interpreted by the Securities and
Exchange Commission under Rule 16b-3 promulgated under the Exchange
Act.)  If administration is delegated to a Committee, the Committee
shall have, in connection with the administration of the Plan, the powers

                                  2
<PAGE>
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.  Notwithstanding anything else in this
subparagraph 2(c) to the contrary, at any time the Board or the
Committee may delegate to a committee of one or more members of the
Board the authority to grant or amend options to all employees,
directors or consultants or any portion or class thereof.

     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 twenty million four hundred thousand (20,400,000) 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 to employees or directors of, or consultants to, the Company
or its Affiliates or to Trusts of any such employee, director or
consultant.

         (b)  A director shall in no event be eligible for the
benefits of the Plan unless and until such director is expressly

                               3
<PAGE>
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 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, the
Plan complies with the requirements of Rule 16b-3 promulgated under
the Exchange Act.  The Board shall otherwise comply with the
requirements of Rule 16b-3 promulgated under the Exchange Act, as
from time to time in effect, unless the Board expressly decides not
to so comply with respect to one or more specified options with the
concurrence of the affected optionee or optionees

         (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 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 such 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)  The term of any option shall not be greater than 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

                               4 
<PAGE>
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; including but not limited to payment of the purchase
price pursuant to a program developed under Regulation T as
promulgated by the Federal Reserve Board which results in the
receipt of cash (or a check) by the Company before Common Stock is
issued or the receipt of irrevocable instructions to pay the
aggregate exercise price to the Company from the sales proceeds
before Common Stock is issued.

    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,

                                 5
<PAGE>
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 federal securities laws.

          (g)  An option shall terminate three (3) months after
termination of the optionee's employment or relationship as a
director or 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 director or consultant; or (ii)
the optionee dies while in the employ of or while serving as a
director or consultant to the Company or an Affiliate, or within not
more than three (3) months after termination of such employment or
relationship as a director or 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;
(iii) the option by its terms specifies that it shall terminate
sooner than three (3) months after termination of the optionee's
employment or relationship as a director or consultant; or (iv) that
it may be exercised more than three (3) months after termination of
the optionee's employment or relationship as a director or
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 director or 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.

                                  6 
<PAGE>
         (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 the Amgen Inc. 1988
Stock Option Plan, if sufficient shares are available under
subparagraph 3(a) of that Plan, and if sufficient shares of Common
Stock are not so available, shall be granted under the Amgen Inc.
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
Nonqualified 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

                                  7
<PAGE>
Re-Load Option.  Any such Re-Load Option shall be subject to the
availability of sufficient shares under the Amgen Inc. 1988 Stock
Option Plan or under the Amgen Inc. 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 Common 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 of 1933, as amended 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 that 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 Common Stock upon exercise of such options unless and until
such authority is obtained.

    7.   USE OF PROCEEDS FROM COMMON 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, director
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
director or consultant, the vesting schedule of options granted to
such employee, director or consultant or to the Trusts of such
employee, director or consultant shall be accelerated by twelve
months for each full year the employee has been employed by or the
director or 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) (without including the
references to directors).

                              8
<PAGE>
         (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 shall affect the right of the Company or
any Affiliate to terminate the employment of any eligible
participant or optionee with or without cause.

    9.   ADJUSTMENTS UPON CHANGES IN COMMON STOCK.

         (a)  If any change 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 other transaction not involving the
receipt of consideration by the Company), 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.  Such adjustments shall be made by the Board or
the Committee, the determination of which shall be final, binding
and conclusive.  (The conversion of any convertible securities of
the Company shall not be treated as a "transaction not involving the
receipt of consideration by the Company".)

          (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.

                                    9
<PAGE>
          (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 of October 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.

    10.  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 9 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:

                                 10
<PAGE>
              (i)    Increase the number of shares reserved for
         options under the Plan;

              (ii)  Materially modify the requirements as to
         eligibility for participation in the Plan;

              (iii)  Materially increase the benefits accruing to
         participants under the Plan; or

              (iv)   Require stockholder approval in order to comply
         with the requirements of Rule 16b-3.

         (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 Incentive Stock Options and/or to
bring the Plan and/or Incentive Stock Options granted under it into
compliance therewith.

         (c)  Rights and obligations under any option granted
before amendment of the Plan shall not be 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.

    11.  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
16, 1994.  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 impaired by suspension or
termination of the Plan, except with the consent of the person to
whom the option was granted.

    12.  EFFECTIVE DATE OF PLAN.

         The Plan shall become effective as determined by the
Board.

                               EXHIBIT

                             AMGEN INC.

          AMENDED AND RESTATED EMPLOYEE STOCK PURCHASE PLAN


     1.   PURPOSE.

          (a)  The purpose of the Amgen Inc. Employee Stock Purchase
Plan (the "Plan") is to provide a means by which employees of Amgen
Inc., a Delaware corporation (the "Company"), and its Affiliates, as
defined in subparagraph 1(b), which are designated as provided in
subparagraph 2(b), 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 its employees, to secure and retain the services of new
employees, and to provide incentives for such persons to exert
maximum efforts for the success of the Company.

          (d)  The Company intends that the rights to purchase stock
of the Company granted under the Plan be considered options issued
under an "employee stock purchase plan" as that term is defined in
Section 423(b) of the Code.

     2.   ADMINISTRATION.

          (a)  The Plan shall be administered by the Board of
Directors (the "Board") of the Company unless and until the Board
delegates administration to a Committee, as provided in subparagraph
2(c).  Whether or not the Board has delegated administration, the
Board shall have the final power to determine all questions of policy
and expediency that may arise in the administration of the Plan.

          (b)  The Board shall have the power, subject to, and within
the limitations of, the express provisions of the Plan:

               (i)   To determine when and how rights to purchase
stock of the Company shall be granted and the provisions of each
offering of such rights (which need not be identical).

               (ii)  To designate from time to time which Affiliates
of the Company shall be eligible to participate in the Plan.

               (iii) To construe and interpret the Plan and rights
granted under it, and to establish, amend and revoke rules and
regulations for its administration.  The Board, in the exercise of

                                  1
<PAGE>
this power, may correct any defect, omission or inconsistency in the
Plan, in a manner and to the extent it shall deem necessary or
expedient to make the Plan fully effective.

               (iv)  To amend the Plan as provided in paragraph 13.

               (v)   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 two (2) members of the Board
(the "Committee").  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.

     3.   SHARES SUBJECT TO THE PLAN.

          (a)  Subject to the provisions of paragraph 12 relating to
adjustments upon changes in stock, the stock that may be sold
pursuant to rights granted under the Plan shall not exceed in the
aggregate six million (6,000,000)(*1) shares of the Company's $.0001
par value common stock (the "Common Stock").  If any right granted
under the Plan shall for any reason terminate without having been
exercised, the Common Stock not purchased under such right shall
again become available for the Plan.

          (b)  The stock subject to the Plan may be unissued shares
or reacquired shares, bought on the market or otherwise.

     4.   GRANT OF RIGHTS; OFFERING.

          The Board or the Committee may from time to time grant or
provide for the grant of rights to purchase Common Stock of the
Company under the Plan to eligible employees (an "Offering") on a
date or dates (the "Offering Date(s)") selected by the Board or the
Committee.  Each Offering shall be in such form and shall contain
such terms and conditions as the Board or the Committee shall deem
appropriate.  If an employee has more than one right outstanding
under the Plan, unless he or she otherwise indicates in agreements or
notices delivered hereunder:  (1) each agreement or notice delivered
by that employee will be deemed to apply to all of his or her rights
under the Plan, and (2) a right with a lower exercise price (or an
earlier-granted right, if two rights have identical exercise prices),
will be exercised to the fullest possible extent before a right with
a higher exercise price (or a later-granted right, if two rights have
identical exercise prices) will be exercised.  The provisions of

                                 2
<PAGE>
separate Offerings need not be identical, but each Offering shall
include (through incorporation of the provisions of this Plan by
reference in the Offering or otherwise) the substance of the
provisions contained in paragraphs 5 through 8, inclusive.

     5.   ELIGIBILITY.

          (a)  Rights may be granted only to employees of the Company
or, as the Board or the Committee may designate as provided in
subparagraph 2(b), to employees of any Affiliate of the Company.
Except as provided in subparagraph 5(b), an employee of the Company
or any Affiliate shall not be eligible to be granted rights under the
Plan, unless, on the Offering Date, such employee has been in the
employ of the Company or any Affiliate for such continuous period
preceding such grant as the Board or the Committee may require, but
in no event shall the required period of continuous employment be
equal to or greater than two (2) years.  In addition, unless
otherwise determined by the Board or the Committee and set forth in
the terms of the applicable Offering, no employee of the Company or
any Affiliate shall be eligible to be granted rights under the Plan,
unless, on the Offering Date, such employee's customary employment
with the Company or such Affiliate is at least twenty (20) hours per
week and at least five (5) months per calendar year.

          (b)  The Board or the Committee may provide that, each
person who, during the course of an Offering, first becomes an
eligible employee of the Company or designated Affiliate will, on a
date or dates specified in the Offering which coincides with the day
on which such person becomes an eligible employee or occurs
thereafter, receive a right under that Offering, which right shall
thereafter be deemed to be a part of that Offering.  Such right shall
have the same characteristics as any rights originally granted under
that Offering, as described herein, except that:

               (i)   the date on which such right is granted shall
be the "Offering Date" of such right for all purposes, including
determination of the exercise price of such right, provided, however,
that if the fair market value of the Common Stock on the date on
which such right is granted is less than the fair market value of the
Common Stock on the first day of the Offering, then, solely for the
purpose of determining the exercise price of such right, the first
day of the Offering shall be the "Offering Date" for such right;

               (ii)  the Purchase Period (as defined below) for such
right shall begin on its Offering Date and end coincident with the
end of such Offering; and

               (iii) the Board or the Committee may provide that if
such person first becomes an eligible employee within a specified
period of time before the end of the Purchase Period (as defined
below) for such Offering, he or she will not receive any right under
that Offering.

                                  3
<PAGE>
          (c)  No employee shall be eligible for the grant of any
rights under the Plan if, immediately after any such rights are
granted, such employee owns stock possessing five percent (5%) or
more of the total combined voting power or value of all classes of
stock of the Company or of any Affiliate.  For purposes of this
subparagraph 5(c), the rules of Section 424(d) of the Code shall
apply in determining the stock ownership of any employee, and stock
which such employee may purchase under all outstanding rights and
options shall be treated as stock owned by such employee.

          (d)  An eligible employee may be granted rights under the
Plan only if such rights, together with any other rights granted
under "employee stock purchase plans" of the Company and any
Affiliates, as specified by Section 423(b)(8) of the Code, do not
permit such employee's rights to purchase stock of the Company or any
Affiliate to accrue at a rate which exceeds twenty-five thousand
dollars ($25,000) of fair market value of such stock (determined at
the time such rights are granted) for each calendar year in which
such rights are outstanding at any time.

          (e)  Officers of the Company shall be eligible to
participate in Offerings under the Plan, provided, however, that the
Board may provide in an Offering that certain employees who are
highly compensated employees within the meaning of Section
423(b)(4)(D) of the Code shall not be eligible to participate.

     6.   RIGHTS; PURCHASE PRICE.

          (a)  On each Offering Date, each eligible employee,
pursuant to an Offering made under the Plan, shall be granted the
right to purchase up to the number of shares of Common Stock of the
Company purchasable with a percentage designated by the Board or the
Committee not exceeding fifteen percent (15%) of such employee's
Earnings (as defined in Section 7(a)) during the period which begins
on the Offering Date (or such later date as the Board or the
Committee determines for a particular Offering) and ends on the date
stated in the Offering, which date shall be no more than twenty-seven
(27) months after the Offering Date (the "Purchase Period").  In
connection with each Offering made under this Plan, the Board or the
Committee shall specify a maximum number of shares which may be
purchased by any employee as well as a maximum aggregate number of
shares which may be purchased by all eligible employees pursuant to
such Offering.  In addition, in connection with each Offering which
contains more than one Exercise Date (as defined in the Offering),
the Board or the Committee may specify a maximum aggregate number of
shares which may be purchased by all eligible employees on any given
Exercise Date under the Offering.  If the aggregate purchase of
shares upon exercise of rights granted under the Offering would
exceed any such maximum aggregate number, the Board or the Committee
shall make a pro rata allocation of the shares available in as nearly
a uniform manner as shall be practicable and as it shall deem to be
equitable.

                                  4
<PAGE>
          (b)  The purchase price of stock acquired pursuant to
rights granted under the Plan shall be not less than the lesser of:

               (i)   an amount equal to eighty-five percent (85%) of
the fair market value of the stock on the Offering Date; or

               (ii)  an amount equal to eighty-five percent (85%) of
the fair market value of the stock on the Exercise Date.

          (c)  Each eligible employee shall have the same rights and
privileges under the Plan, except as allowed under Section 423(b)(5)
of the Code.

     7.   PARTICIPATION; WITHDRAWAL; TERMINATION.

          (a)  An eligible employee may become a participant in an
Offering by delivering a participation agreement to the Company
within the time specified in the Offering, in such form as the
Company provides.  Each such agreement shall authorize payroll
deductions of up to the maximum percentage specified by the Board or
the Committee of such employee's Earnings during the Purchase Period.
"Earnings" is defined as the total compensation paid to an employee,
including all salary, wages (including amounts elected to be deferred
by the employee, that would otherwise have been paid, under any cash
or deferred arrangement established by the Company), overtime pay,
commissions, bonuses, and other remuneration paid directly to the
employee, but excluding profit sharing, the cost of employee benefits
paid for by the Company, education or tuition reimbursements, imputed
income arising under any Company group insurance or benefit program,
traveling expenses, business and moving expense reimbursements,
income received in connection with stock options, contributions made
by the Company under any employee benefit plan, and similar items of
compensation, or such other inclusions or exclusions as the Board or
Committee may determine for one or more specified Offerings.  The
payroll deductions made for each participant shall be credited to an
account for such participant under the Plan and shall be deposited
with the general funds of the Company.  A participant may reduce
(including to zero), increase or begin such payroll deductions after
the beginning of any Purchase Period only as provided for in the
Offering.  A participant may make additional payments into his or her
account only if specifically provided for in the Offering and only if
the participant has not had the maximum amount withheld during the
Purchase Period.

          (b)  At any time during a Purchase Period a participant may
terminate his or her payroll deductions under the Plan and withdraw
from the Offering by delivering to the Company a notice of withdrawal
in such form as the Company provides.  Such withdrawal may be elected
at any time prior to the end of the Purchase Period except as
provided by the Board or the Committee in the Offering.  Upon such
withdrawal from the Offering by a participant, the Company shall
distribute to such participant all of his or her accumulated payroll
deductions

                                 5
<PAGE>
(reduced to the extent, if any, such deductions have been used to
acquire stock for the participant) under the Offering, without
interest, and such participant's interest in that Offering shall be
automatically terminated.  A participant's withdrawal from an
Offering will have no effect upon such participant's eligibility to
participate in any other Offerings under the Plan but such
participant will be required to deliver a new participation agreement
in order to participate in subsequent Offerings under the Plan.

          (c)  Rights granted pursuant to any Offering under the Plan
shall terminate immediately upon cessation of any participating
employee's employment with the Company or an Affiliate, for any
reason, and the Company shall distribute to such terminated employee
all of his or her accumulated payroll deductions (reduced to the
extent, if any, such deductions have been used to acquire stock for
the terminated employee), under the Offering, without interest.

          (d)  Rights granted under the Plan shall not be
transferable, and shall be exercisable only by the person to whom
such rights are granted.

     8.   EXERCISE.

          (a)  On each exercise date, as defined in the relevant
Offering (an "Exercise Date"), each participant's accumulated payroll
deductions and other additional payments specifically provided for in
the Offering (without any increase for interest) will be applied to
the purchase of whole shares of stock of the Company, up to the
maximum number of shares permitted pursuant to the terms of the Plan
and the applicable Offering, at the purchase price specified in the
Offering.  No fractional shares shall be issued upon the exercise of
rights granted under the Plan.  The amount, if any, of accumulated
payroll deductions remaining in each participant's account after the
purchase of shares which is less than the amount required to purchase
one share of stock on the final Exercise Date of an Offering shall be
held in each such participant's account for the purchase of shares
under the next Offering under the Plan, unless such participant
withdraws from such next Offering, as provided in subparagraph 7(b),
or is no longer eligible to be granted rights under the Plan, as
provided in paragraph 5, in which case such amount shall be
distributed to the participant after said final Exercise Date,
without interest.  The amount, if any, of accumulated payroll
deductions remaining in any participant's account after the purchase
of shares which is equal to the amount required to purchase whole
shares of stock on the final Exercise Date of an Offering shall be
distributed in full to the participant after such Exercise Date,
without interest.

          (b)  No rights granted under the Plan may be exercised to
any extent unless the Plan (including rights granted thereunder) is
covered by an effective registration statement pursuant to the
Securities Act of 1933, as amended (the "Securities Act").  If on an

                                6
<PAGE>
Exercise Date of any Offering hereunder the Plan is not so
registered, no rights granted under the Plan or any Offering shall be
exercised on said Exercise Date and the Exercise Date shall be
delayed until the Plan is subject to such an effective registration
statement, except that the Exercise Date shall not be delayed more
than two (2) months and the Exercise Date shall in no event be more
than twenty-seven (27) months from the Offering Date.  If on the
Exercise Date of any Offering hereunder, as delayed to the maximum
extent permissible, the Plan is not registered, no rights granted
under the Plan or any Offering shall be exercised and all payroll
deductions accumulated during the purchase period (reduced to the
extent, if any, such deductions have been used to acquire stock)
shall be distributed to the participants, without interest.

     9.   COVENANTS OF THE COMPANY.

          (a)  During the terms of the rights granted under the Plan,
the Company shall keep available at all times the number of shares of
stock required to satisfy such rights.

          (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 rights granted under the Plan.  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 rights unless and until such authority is
obtained.

     10.  USE OF PROCEEDS FROM STOCK.

          Proceeds from the sale of stock pursuant to rights granted
under the Plan shall constitute general funds of the Company.

     11.  RIGHTS AS A STOCKHOLDER.

          A participant shall not be deemed to be the holder of, or
have any of the rights of a holder with respect to, any shares
subject to rights granted under the Plan unless and until
certificates representing such shares have been issued or such shares
have been credited to an account held by a bank, broker or other
nominee of the participant.

     12.  ADJUSTMENTS UPON CHANGES IN STOCK.

          (a)  If any change is made in the stock subject to the
Plan, or subject to any rights 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

                                 7
<PAGE>
corporate structure or other transaction not involving the receipt of
consideration by the Company), the Plan and outstanding rights will
be appropriately adjusted in the class(es) and maximum number of
shares subject to the Plan and the class(es) and number of shares and
price per share of stock subject to outstanding rights.  Such
adjustments shall be made by the Board or the Committee, the
determination of which shall be final, binding and conclusive.  (The
conversion of any convertible securities of the Company shall not be
treated as a "transaction not involving the receipt of consideration
by the Company".)

          (b)  In the event of:  (1) a dissolution or liquidation of
the Company; (2) a merger or consolidation in which the Company is
not the surviving corporation; (3) a reverse merger in which the
Company is the surviving corporation but the shares of the Company's
Common Stock outstanding immediately preceding the merger are
converted by virtue of the merger into other property, whether in the
form of securities, cash or otherwise; or (4) any other capital
reorganization in which more than fifty percent (50%) of the shares
of the Company entitled to vote are exchanged, then, as determined by
the Board in its sole discretion (i) any surviving corporation may
assume outstanding rights or substitute similar rights for those
under the Plan, (ii) such rights may continue in full force and
effect, or (iii) participants' accumulated payroll deductions may be
used to purchase Common Stock immediately prior to the transaction
described above and the participants' rights under the ongoing
Offering terminated.

     13.  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 12 relating
to adjustments upon changes in 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
rights under the Plan;

               (ii)  Modify the provisions as to eligibility for
participation in the Plan (to the extent such modification requires
stockholder approval in order for the Plan to obtain employee stock
purchase plan treatment under Section 423 of the Code); or

               (iii)  Modify the Plan in any other way if such
modification requires stockholder approval in order for the Plan to
obtain employee stock purchase plan treatment under Section 423 of
the Code.

     It is expressly contemplated that the Board may amend the Plan
in any respect the Board deems necessary or advisable to provide
eligible employees with the maximum benefits provided or to be provided

                                 8
<PAGE>
under the provisions of the Code and the regulations promulgated thereunder
relating to employee stock purchase plans and/or to bring the Plan
and/or rights granted under it into compliance therewith.

          (b)  Rights and obligations under any rights granted before
amendment of the Plan shall not be impaired by any amendment of the
Plan, except with the consent of the person to whom such rights were
granted or except as necessary to comply with any laws or
governmental regulation.

     14.  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 ten (10)
years from the date the Plan is adopted by the Board or approved by
the stockholders of the Company, whichever is earlier.  No rights may
be granted under the Plan while the Plan is suspended or after it is
terminated.

          (b)  Rights and obligations under any rights 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 such rights were granted or except as necessary to comply with
any laws or governmental regulation.

     15.  EFFECTIVE DATE OF PLAN.

          The Plan shall become effective as determined by the Board.

                             AMGEN INC.

       AMENDED AND RESTATED 1987 DIRECTORS' STOCK OPTION PLAN


1.   PURPOSE.

    (a)  The purpose of the 1987 Directors' Stock Option Plan (the
"Plan") is to provide a means by which each director of AMGEN INC.
(the "Company") and its Affiliates, as defined in subparagraph 1(b),
who is not otherwise an employee of the Company or any Affiliate
(each such person being hereafter referred to as a "Non-Employee
Director") 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 serving as Non-Employee Directors of the
Company, to secure and retain the services of persons capable of
serving in such capacity, 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
not be incentive stock options as that term is used in Section 422 of
the Code.

2.   ADMINISTRATION.

    (a)  The Plan shall be administered by the Board of Directors
(the "Board") of the Company 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 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.

         (2)  To amend the Plan as provided in paragraph 11.

         (3)  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.

                                 1
<PAGE>
    (c)  The Board may delegate administration of the Plan to a
committee composed of not fewer than two (2) members of the Board
(the "Committee").  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.

3.   SHARES SUBJECT TO THE PLAN.

    (a)  Subject to the provisions of paragraph 10 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 one million eight hundred thousand (1,800,000) shares of
the Company's common stock.  If any option granted under the Plan
shall for any reason expire or otherwise terminate without having
been exercised in full, the stock not purchased under such option
shall again become available for the Plan.

    (b)  The stock subject to the Plan may be unissued shares or
reacquired shares, bought on the market or otherwise.

4.   ELIGIBILITY.

    Options shall be granted only to Non-Employee Directors of the
Company, or an affiliate of such Non-Employee Directors.

5.   NON-DISCRETIONARY GRANTS.

    (a)  On January 27 of each year commencing January 27, 1992,
each person who is at that time a Non-Employee Director of the
Company, or an affiliate of such Non-Employee Director, shall
automatically be granted under the Plan, without further action by
the Company, the Board, or the Company's stockholders, an option to
purchase three thousand five hundred (3,500) shares of common stock
of the Company on the terms and conditions set forth herein.  The
number of shares to be granted hereunder shall not be adjusted as
provided for in subparagraph 10(a), but, however, shall be adjusted
by multiplying by a fraction, the numerator of which is forty dollars
($40.00) per share and the denominator of which is the fair market
value of the common stock of the Company on the date of grant.  The
number of shares granted pursuant to this subparagraph 5(a) shall be
rounded to the nearest one hundred (100) shares (rounding up if 50
shares); notwithstanding the foregoing, the number of shares that
shall be granted pursuant to this subparagraph 5(a) shall not be less
than two thousand (2,000) nor shall it exceed five thousand (5,000)
shares.  The option shall be on the terms and conditions set forth
herein and should the date of grant set forth above be a Saturday,
Sunday or legal holiday, such grant shall be made on the next
business day.

                                    2
<PAGE>
    (b)  Each person who, after January 27 of any year commencing
January 27, 1991 and prior to November 1 of any year, becomes a Non-
Employee Director, or an affiliate of such Non-Employee Director,
shall, upon the date he or such affiliate becomes a Non-Employee
Director, automatically be granted under the Plan, without further
action by the Company, the Board, or the Company's stockholders, an
option to purchase three thousand five hundred (3,500) shares of
common stock of the Company on the terms and conditions set forth
herein.  The number of shares to be granted hereunder shall not be
adjusted as provided for in subparagraph 10(a), but, however, shall
be adjusted by multiplying by a fraction, the numerator of which is
forty dollars ($40.00) per share and the denominator of which is the
fair market value of the common stock of the Company on the date of
grant.  The number of shares granted pursuant to this subparagraph
5(b) shall be rounded to the nearest one hundred (100) shares
(rounding up if 50 shares); notwithstanding the foregoing, the number
of shares that shall be granted pursuant to this subparagraph 5(b)
shall not be less than two thousand (2,000) nor shall it exceed five
thousand (5,000) shares.  The option shall be on the terms and
conditions set forth herein and should the date of grant set forth
above be a Saturday, Sunday or legal holiday, such grant shall be
made on the next business day.

6.   OPTION PROVISIONS.

    Each option shall be in such 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)  The term of each option shall be ten (10) years from the
date it was granted.

    (b)  The exercise price of each option shall be one hundred
percent (100%) of the fair market value of the stock subject to such
option on the date such option is granted.

    (c)  The purchase price of 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) by delivery to the Company of shares of common stock that
have been held for the period required to avoid a charge to the
Company's reported earnings and valued at their fair market value on
the date of exercise.  Options granted under the Plan that are
outstanding on April 2, 1991, shall be amended to include the right
to exercise with common stock of the Company as provided for in this
subparagraph 6(c).

    (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 an affiliate

                                   3
<PAGE>
of such person to be such person's beneficiary with respect to the
Option, and such beneficiary shall, after the death of the person to
whom the Option was granted, have all of the rights that such person
had 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)  An option shall not vest with respect to each optionee (i)
unless the optionee, or the affiliate of such optionee, as the case
may be, has, at the date of grant, provided three (3) years of prior
continuous service as a Non-Employee Director, or (ii) until the date
upon which such optionee or the affiliate of such optionee, as the
case may be, has provided one year of continuous service as a Non-
Employee Director following the date of grant of such option,
whereupon such option shall become fully exercisable in accordance
with its terms, provided that, if the optionee, or the affiliate of
such optionee, as the case may be, has, at the date of grant,
provided three (3) years of prior continuous service as a Non-
Employee Director, such option shall not become exercisable for six
(6) months after the date of grant (even though such option shall be
fully vested as of the date of grant).

    (f)  The Company may require any optionee, or any person to whom
an option is transferred under subparagraph 6(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 (2) to give written
assurances satisfactory to the Company stating that such person is
acquiring the stock subject to the option for such person's own
account and not with any present intention of selling or otherwise
distributing the 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 laws.

    (g)  Subject to the last sentence of this subparagraph 6(g),
each option granted after April 2, 1991, under the Plan shall include
and all outstanding options under the Plan on April 2, 1991 shall be
amended to include a provision entitling the optionee to a further
option (a "Reload Option") in the event the optionee exercises the
option evidenced by the option grant, in whole or in part, by
surrendering other shares of common stock of the Company in
accordance with the Plan and the terms of the option grant.  Any such
Reload 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 the
original option; (ii) shall have an expiration date which is the same

                                 4
<PAGE>
as the expiration date of the original option; and (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 Reload Option on
the date of exercise of the original option.  Any such Reload Option
shall be subject to the availability of sufficient shares under
subparagraph 3(a).  There shall be no Reload Option on a Reload
Option.

7.   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 stock issued or issuable pursuant to any such option.  If 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.

8.   USE OF PROCEEDS FROM STOCK.

    Proceeds from the sale of stock pursuant to options granted
under the Plan shall constitute general funds of the Company.

9.   MISCELLANEOUS.

    (a)  Neither an optionee nor any person to whom an option is
transferred under subparagraph 6(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.

    (b)  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 stockholders of the Company
provided for in the by-laws of the Company and such other information
regarding the Company as the holder of such option may reasonably request.

10.  ADJUSTMENTS UPON CHANGES IN STOCK.

    (a)  If any change is made in the 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 other transaction not involving the receipt of
consideration by the Company), the Plan and outstanding options will
be appropriately adjusted in the class(es) and maximum number of
shares subject to the Plan and the class(es) and number of shares and
price per share of stock subject to outstanding options; provided,
that the minimum and maximum number of shares of common stock to be
granted as provided for in subparagraphs 5(a) and 5(b) shall not be
adjusted for any stock split, combination of shares or common stock
dividend.  Such adjustments shall be made by the Board, the
determination of which shall be final, binding and conclusive.  (The
conversion of any convertible securities of the Company shall not be
treated as a "transaction not involving the receipt of consideration
by the Company".)

     (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 Securities Exchange Act of 1934
as amended (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 of October 23,
1995, constitute the Board (the "Incumbent Board") cease for any

                                6
<PAGE>
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.

11.  AMENDMENT OF THE PLAN

    (a)  The Board at any time, and from time to time, may amend the
Plan and/or some or all outstanding options granted under the Plan;
provided, however, that the Board shall not amend the Plan more than
once every six months with respect to the provisions of the Plan
relating to the amount, price, and timing of grants, other than to
comply with changes in the Code, the Employee Retirement Income
Security Act of 1974, as amended, or the rules thereunder.

    (b)  Rights and obligations under any option granted before
amendment of the Plan shall not be impaired by any amendment of the
Plan, except with the consent of the person to whom the option was
granted.

12.  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 ten (10) years
from the date the Plan is adopted by the Board.  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 impaired by suspension or termination
of the Plan, except with the consent of the person to whom the option
was granted.

13.  EFFECTIVE DATE OF PLAN.

    The Plan became effective as of January 27, 1987.  No options
granted under the Plan as the result of the amendments on July 24,
1990 and 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.

    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

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 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

Incentive Stock Option or a Nonqualified Stock Option; the provisions
of each option granted (which need not be identical), including the

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

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.  Notwithstanding anything to the contrary in this
subparagraph 2(c), at any time the Board or the Committee may
delegate to a committee of one or more members of the Board the
authority to grant or amend options to all employees, directors or
consultants or any portion or class thereof.

         (d)  The term "Non-Employee Director" shall mean a member
of the Board who (i) is not currently an officer of the Company or a
parent or subsidiary of the Company (as defined in Rule 16a-1(f)
promulgated by the Securities and Exchange Commission under Section
16 of the Securities Exchange Act of 1934, as amended (the "Exchange
Act")) or an employee of the Company or a parent or subsidiary of the
Company; (ii) does not receive compensation from the Company or a
parent or subsidiary of the Company for services rendered in any
capacity other than as a member of the Board (including a consultant)
in an amount required to be disclosed to the Company's stockholders
under Rule 404 of Regulation S-K promulgated by the Securities and
Exchange Commission ("Rule 404"); (iii) does not possess an interest

                                  2
<PAGE>
in any other transaction required to be disclosed under Rule 404; or
(iv) is not engaged in a business relationship required to be
disclosed under Rule 404, as all of these provisions are interpreted
by the Securities and Exchange Commission under Rule 16b-3
promulgated under the Exchange Act.

         (e)  Any requirement that an administrator of the Plan be a
"Non-Employee Director" 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 or directors of, or consultants to, the Company or
its Affiliates (including officers who so qualify) or to Trusts of
any such employee, director or consultant.

         (b)  A director shall in no event be eligible for the
benefits of the Plan unless and until such director is expressly

                                   3
<PAGE>
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, the
Plan 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, unless the
Board expressly decides not to so comply with respect to one or more
specified options with the concurrence of the affected optionee or
optionees.

         (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 such 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

                                   4
<PAGE>
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; including but not
limited to payment of the purchase price pursuant to a program
developed under Regulation T as promulgated by the Federal Reserve
Board which results in the receipt of cash (or a check) by the
Company before Common Stock is issued or the receipt of irrevocable
instructions to pay the aggregate exercise price to the Company from
the sales proceeds before Common Stock is issued.

    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

                                  5
<PAGE>
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
director or 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 director or consultant; (ii) the
optionee dies while in the employ of or while serving as a director
or consultant to the Company or an Affiliate, or within not more than
three (3) months after termination of such employment or relationship
as a director or 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 director or consultant, or (B) that it may be
exercised more than three (3) months after termination of the
optionee's employment or relationship as a director or 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 director or
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 director or 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

                                 6
<PAGE>
following means or by a combination of such means: (1) tendering a
cash payment; (2) authorizing the Company to withhold from the shares
of 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 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 Amgen Inc. 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 Nonqualified
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 Amgen Inc. 1991 Equity Incentive Plan and shall be subject to
such other terms and conditions as the Board or Committee may
determine.

                                   7 
<PAGE>
    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 of 1933, as amended, 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 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,
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's employment or a director's or
consultant's affiliation with the Company is terminated by reason of
death or disability (within the meaning of Title II or XVI of the
Social Security Act and as determined by the Social Security
Administration), the vesting schedule of options granted to such
employee, director or consultant or to the Trusts of such employee,
director or consultant shall be accelerated by twelve months for each
full year the employee has been employed by or the director or
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 upon death provided for in
the preceding sentence of this paragraph 8(a) and options granted
under the Plan that are outstanding on June 18, 1996, shall be
amended to include the accelerated vesting upon disability provided
for in the preceding sentence of this paragraph 8(a) (without
including references to directors).

         (b)  Neither an optionee nor any person to whom an option
is transferred under subparagraph 5(d) shall be deemed to be the holder

                                    8
<PAGE>
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 director or 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 change 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 other transaction not involving the
receipt of consideration by the Company), the Plan and outstanding

                                 9                                  
<PAGE>
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.  Such adjustments shall be made by the Board or
the Committee, the determination of which shall be final, binding and
conclusive.  (The conversion of any convertible securities of the
Company shall not be treated as a "transaction not involving the
receipt of consideration by the Company".)

          (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 of October 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

                                  10
<PAGE>
               (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.

                                   11 
<PAGE>
    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

              (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.

         (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 Incentive Stock Options and/or to
bring the Plan and/or Incentive Stock Options granted under it into
compliance therewith.

         (c)  Rights and obligations under any option granted before
amendment of the Plan shall not be impaired by any amendment of the
Plan, unless:  (i) the Company requests the consent of the person to

                       FIRST AMENDMENT TO THE
                  AMGEN RETIREMENT AND SAVINGS PLAN
           AS AMENDED AND RESTATED EFFECTIVE APRIL 1, 1996


     The Amgen Retirement and Savings Plan (as amended and restated
effective April 1, 1996) (the "Plan") is hereby amended, effective as
of October 22, 1996, in the following respects:

1.   Section 6.9 of the Plan is amended to read in its entirety as 
     follows:

          6.9  Transfers Among Investment Funds.  A Participant may
     elect to reapportion the values of his or her Accounts among
     Investment Funds by properly following procedures prescribed by
     the Company.  The Company's procedures by which a Participant
     may elect to transfer amounts into or out of the Company Stock
     Fund shall be drafted to provide notice to Participants if such
     an election would cause a Participant to have a purchase or sale
     of Company Stock which is not exempt from potential short-swing
     trading profits liability under Section 16(b) of the Exchange
     Act by virtue of the application of Rule 16b-3 (promulgated
     under Section 16 of the Exchange Act) as in effect from time to
     time.  As of the effective date of this amended and restated
     Plan, such liability may arise if such election is made by a
     Participant (or successor in interest) who is an officer,
     director, or greater than 10% stockholder of the Company (within
     the meaning of Section 16 of the Exchange Act and the rules
     promulgated thereunder) within six months following the date of
     the most recent election made under any employee benefit plan
     sponsored by the Company or an Affiliate if (a) both elections
     involved either an intra-plan transfer involving a fund invested
     in the Company's equity securities or a cash distribution from
     the employee benefit plan to the Participant (or successor in
     interest) funded by a volitional disposition of the Company's
     equity securities, (b) the prior election involved an
     acquisition of the Company's equity securities if the current
     election involves a disposition of the Company's equity
     securities, or vice versa, and (c) both elections are made at
     the volition of the Participant (or successor in interest) not
     in connection with the Participant's death, disability,
     retirement, termination of employment, or an election which is
     required to be made available under a provision of the Code.
     Such a volitional election (considering without regard as to
     whether or not any similar elections have occurred within six
     months of such an election) shall be described as a
     "Discretionary Transaction."  Prior to July 1, 1996,
     Participants may not elect to transfer amounts to the Company
     Stock Fund.  On and after July 1, 1996, transfers into the
     Company Stock Fund shall be limited so that, after any such
     transfer, no more than 50% of the value of the Participant's
     aggregate Account is invested in the Company Stock Fund.  For
     purposes of carrying out Investment Fund transfers, the value of
     the Accounts shall be determined as of the Valuation Date
     immediately preceding the Participant's transfer election.

                                   1
<PAGE>
2.   Section 8.6(d) of the Plan is amended to read in its entirety as
     follows:

               (d)  The Company shall establish procedures to notify
     a Participant (or successor in interest) if any election
     regarding the form or timing of distribution of benefits from
     the Plan involving the Company Stock Fund constitutes a
     Discretionary Transaction (as defined in Section 6.9) which may
     trigger short-swing trading profits liability for the
     Participant (or successor in interest) under Section 16(b) of
     the Exchange Act.  In such an event, the person making the
     election shall be provided with a reasonable opportunity to
     modify, delay, or revoke such an election.

3.   Section 10.4 of the Plan is amended to read in its entirety as
     follows:

          10.4 Source of Loans.  If a Participant requests and is
     granted a loan, a Loan Account shall be established for the
     Participant.  The Loan Account shall be held by the Trustee as
     part of the Loan Fund.  The amount of the loan shall be
     transferred to the Participant's Loan Account from the
     Participant's other Accounts and shall be disbursed from the
     Loan Account. Transfers from the Company Stock Fund shall be
     made in accordance with the requirements for exemption under
     Section 16(b) of the Exchange Act if such a transfer would cause
     the Participant to incur short-swing trading profits liability
     under Section 16(b) of the Exchange Act.  The promissory note
     executed by the Participant shall be held by the Trustee (or by
     the Company as agent of the Trustee) and the promissory note
     shall be treated as an investment of the Participant's Loan
     Account.

4.   Section 11.6 of the Plan is amended to read in its entirety as
     follows:

          11.6 Source of Withdrawals.  Withdrawals shall be paid from
     the affected Accounts.  If more than one Account is available to
     pay the withdrawal because the Participant elected to invest in
     more than one Investment Fund, the withdrawal shall be made from
     the subaccount(s) designated by the Participant, subject to such
     ordering and timing restrictions as the Company may adopt.

5.   Section 11.8 of the Plan is amended to read in its entirety as
     follows:

          11.8 Limitations on Withdrawals.  A Participant shall not
     be permitted to make more than one withdrawal under this Article
     in any period of six consecutive months; provided, however, that
     withdrawals made at the same time shall be considered a single
     withdrawal.  The timing of withdrawals from the Company Stock
     Fund shall be limited when necessary to avoid liability from the
     short-swing trading profits provisions of Section 16(b) of the
     Exchange Act.

                                      2

Factors That May Affect Future Results

     Amgen operates in a rapidly changing environment that involves a
number of risks, some of which are beyond the Company's control.  The
following discussion highlights  some of these  risks and others  are
discussed elsewhere  herein  and  in other  documents  filed  by  the
Company with the Securities and Exchange Commission.

  Period to period fluctuations

     The Company's operating  results may fluctuate  for a number  of
reasons.  The forecasting  of revenue is  inherently uncertain for  a
variety  of  reasons.    Because  the  Company  plans  its  operating
expenses, many of which  are relatively fixed in  the short term,  on
the basis  that revenues  will continue  to grow,  even a  relatively
small revenue  shortfall may  cause a  period's results  to be  below
expectations.  Such a revenue shortfall  could arise from any  number
of factors, including lower than expected demand, wholesalers' buying
patterns,  product  pricing   strategies,  fluctuations  in   foreign
currency  exchange   rates,   changes  in   government   or   private
reimbursement, transit interruptions, overall economic conditions  or
natural disasters (including earthquakes).

     See  "Results  of  Operations  -  Product  sales  -  NEUPOGEN(R)
(Filgrastim)" for a discussion regarding quarterly NEUPOGEN(R) sales.

     The Company's  stock price,  like  that of  other  biotechnology
companies, is  subject to  significant volatility.   If  revenues  or
earnings in  any  quarter fail  to  meet the  investment  community's
expectations, there could  be an  immediate impact  on the  Company's
stock price.  The  stock price may also  be affected by, among  other
things, clinical trial results and other product development  related
announcements  by  Amgen  or  its  competitors,  regulatory  matters,
intellectual property  and legal  matters,  or broader  industry  and
market trends unrelated to the Company's performance.

  Rapid growth

     In light  of  management's views  of  the potential  for  future
growth  of  the  Company's  business,  the  Company  has  adopted  an
aggressive  growth  plan  that  includes  substantial  and  increased
investments in research and development and investments in facilities
that will  be required  to support  significant  growth.   This  plan
carries with  it a  number  of risks,  including  a higher  level  of
operating expenses, the difficulty  of attracting and assimilating  a
large number of new employees,  and the complexities associated  with
managing a larger and faster growing organization.

  Product development

     The Company intends to  continue to develop product  candidates.
Successful product  development  in  the  biotechnology  industry  is
highly  uncertain  and  only  a   small  minority  of  research   and
development programs  ultimately  result in  commercially  successful
drugs.  Product development is dependent on numerous factors, many of
which are  beyond the  Company's control.   Product  candidates  that
appear promising in the early phases of development may fail to reach

                                  1 
<PAGE>
market for numerous reasons.  They may be found to be ineffective  or
to have harmful side effects in clinical or preclinical testing, fail
to receive necessary regulatory  approvals, be uneconomic because  of
manufacturing  costs  or   other  factors,  or   be  precluded   from
commercialization by the  proprietary rights of  others.  Success  in
preclinical and  early clinical  trials does  not ensure  that  large
scale clinical  trials  will be  successful.   Clinical  results  are
frequently susceptible to  varying interpretations  which may  delay,
limit  or  prevent   further  clinical   development  or   regulatory
approvals.  The length of time necessary to complete clinical  trials
and receive approval for product marketing by regulatory  authorities
varies significantly by product and indication and is often difficult
to predict.

  Regulatory approvals

     The success of current products and future product candidates of
the Company  will  depend  in part  upon  maintaining  and  obtaining
regulatory  approval  to  market  products.    Domestic  and  foreign
statutes and  regulations govern  matters relating  to the  Company's
products and  product candidates  and  the research  and  development
activities associated with  them.  The  Company's product  candidates
may prove  to have  undesirable side  effects that  may interrupt  or
delay clinical studies  and could ultimately  prevent or limit  their
commercial use.  The Company or regulatory authorities may suspend or
terminate clinical trials  at any time  if the  participants in  such
trials are believed to be exposed to unacceptable health risks.  Even
if regulatory  approval  is  obtained, a  marketed  product  and  its
manufacturer are subject  to continued  review.   Later discovery  of
previously unknown problems with a product or manufacturer may result
in restrictions on such product or manufacturer, including withdrawal
of the  product  from  the  market.    Failure  to  obtain  necessary
approvals, or  the  restriction,  suspension, or  revocation  of  any
approvals, or  the failure  to  comply with  regulatory  requirements
could have a material adverse effect on the Company.

  Reimbursement

     The success of the Company's products partially depends upon the
extent to which a  consumer is willing  to pay the  price or able  to
obtain reimbursement for the cost  of these products from  government
health administration authorities, private health insurers, and other
organizations.     Significant   uncertainties  exist   as   to   the
reimbursement status  of  newly approved  therapeutic  products,  and
current reimbursement policies for existing products may change.   It
is possible  that  changes  in reimbursement  or  failure  to  obtain
reimbursement may reduce the demand for or the price of the Company's
products.

     Several factors could influence the pricing or reimbursement for
the Company's products including:  (1) third-party payors  continuing
to challenge the  prices charged for  medical services and  products,
(2) the trend  towards managed  care in  the United  States, (3)  the
growth  of  organizations  which   could  control  or   significantly
influence the purchase of health care services and products, and  (4)
legislative proposals  to reform  health  care or  reduce  government
insurance programs.  NEUPOGEN(R)  usage has been  and is expected  to

                                    2
<PAGE>
continue to be affected by cost containment pressures on health  care
providers worldwide.   In addition, patients  receiving EPOGEN(R)  in
connection with treatment  for end  stage renal  disease are  covered
primarily under medical programs provided by the federal  government.
Therefore, EPOGEN(R) sales may also be affected by future changes  in
reimbursement rates or  the basis  for reimbursement  by the  federal
government.

  Competition

     Substantial competition  exists  in the  biotechnology  industry
from  pharmaceutical  and  biotechnology  companies  which  may  have
technical or competitive advantages.  The Company competes with these
companies in  the  development  of  technologies  and  processes  and
sometimes competes with  them in acquiring  technology from  academic
institutions, government  agencies,  and  other  private  and  public
research organizations.  There can be  no assurance that the  Company
will be  able to  produce or  acquire rights  to products  that  have
commercial  potential.    Even   if  the  Company  achieves   product
commercialization, there can be no assurance that one or more of  the
Company's competitors may not: (1) achieve product  commercialization
earlier  than  the  Company,  (2)  receive  patent  protection   that
dominates or adversely affects the Company's activities, or (3)  have
significantly greater marketing capabilities.

     The field of biotechnology  has undergone rapid and  significant
technological change.    The  Company  expects  that  the  technology
associated with the Company's research and development will  continue
to develop rapidly, and the Company's  future success will depend  in
large part on  its ability to  maintain a  competitive position  with
respect to this technology.   Rapid technological development by  the
Company or  others  may  result in  some  of  the  Company's  product
candidates, products,  or  processes  becoming  obsolete  before  the
Company recovers a significant portion of the research,  development,
manufacturing, and commercialization expenses it incurs.  This  could
have a material adverse effect on the Company.

  Intellectual property and legal matters

     The  patent  positions   of  pharmaceutical  and   biotechnology
companies can  be  highly uncertain  and  involve complex  legal  and
factual questions.  Accordingly the breadth of claims allowed in such
companies' patents cannot be predicted.  Patent disputes are frequent
and can preclude commercialization of products.   The Company is  and
may in the future  be involved in material  patent litigation.   Such
litigation, if  decided  adversely,  could  subject  the  Company  to
significant liabilities and cause the  Company to obtain third  party
licenses or cease using the technology or product in dispute.

     The Company is  involved in arbitration  proceedings with  Ortho
Pharmaceutical  Corporation,  a  subsidiary  of  Johnson  &   Johnson
("Johnson & Johnson"), relating to a  license granted by the  Company
to Johnson & Johnson for sales  of Epoetin alfa in the United  States
for all human uses  except dialysis and diagnostics.   See Note 4  to
the Condensed Consolidated  Financial Statements  - "Contingencies  -
Johnson and Johnson arbitrations."  While it is impossible to predict
accurately or  determine  the  outcome of  these  proceedings,  based

primarily upon  the  merits of  its  claims and  based  upon  certain
liabilities established  due  to  the  inherent  uncertainty  of  any
arbitrated result, the  Company believes  that the  outcome of  these
proceedings will not have a material adverse effect on its  financial
statements.  However, it is possible that an adverse decision  could,
depending on its  magnitude, have a  material adverse  effect on  the
financial statements.
