                       FACTORS THAT MAY AFFECT FUTURE RESULTS

            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


                                       1
                                        


            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 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


                                       2





            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  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.
                                        
                                       3
                                        


                 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.
