                NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

                                 September 30, 1997


        1.   Summary of significant accounting policies

          Business


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

          Principles of consolidation

             The 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):

          Product sales

             Product sales consist of two products, EPOGEN(R) (Epoetin alfa),
        NEUPOGEN(R) (Filgrastim).

             Quarterly NEUPOGEN(R)  sales  volume  in the  United  States  is
        influenced by a  number of  factors including  underlying demand  and
                                     8<PAGE>
                                      


        wholesaler inventory  management  practices.    Wholesaler  inventory
        reductions tend to  reduce domestic  NEUPOGEN(R) sales  in the  first
        quarter each year.   In addition, the  discretionary aspects of  some
        cancer chemotherapy administration has  had a slight seasonal  effect
        on NEUPOGEN(R) sales.

             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  Company shipments  and  from
        third-party data on shipments to end users and their usage (see  Note
        4, "Contingencies - Johnson & Johnson arbitrations").

          Foreign currency transactions

             The Company has a program to  manage foreign currency risk.   As
        part of this program,  it has purchased  foreign currency option  and
        forward contracts to hedge against  possible reductions in values  of
        certain anticipated foreign  currency cash flows  generally over  the
        next 12 months,  primarily resulting from  its sales in  Europe.   At
        September 30, 1997, the Company had  option and forward contracts  to
        exchange foreign currencies  for U.S.  dollars of  $49.1 million  and
        $15.2 million, respectively, all having maturities of nine months  or
        less.  The option contracts, which have only nominal intrinsic  value
        at the time of  purchase, are designated and  effective as hedges  of
        anticipated foreign  currency  transactions for  financial  reporting
        purposes, and  accordingly,  the  net gains  on  such  contracts  are
        deferred and will  be recognized  in the  same period  as the  hedged
        transactions.  The  forward contracts do  not qualify  as hedges  for
        financial reporting purposes, and accordingly, are  marked-to-market.
        Net gains on option contracts (including option contracts for  hedged
        transactions whose occurrence are no longer probable) and changes  in
        market values  of forward  contracts are  reflected in  interest  and
        other income.   The deferred premiums  on option  contracts and  fair
        values of forward contracts are included in other current assets.

             The Company has additional foreign currency forward contracts to
        hedge  exposures  to   foreign  currency   fluctuations  of   certain
        receivables and  payables  denominated  in foreign  currencies.    At
        September 30, 1997,  the Company  had forward  contracts to  exchange
        foreign currencies, primarily Swiss francs, for U.S. dollars of $62.9
        million, all  having  maturities of  eight  months or  less.    These
        contracts are designated  and effective as  hedges, and  accordingly,
        gains and losses  on these forward  contracts are  recognized in  the
        same period  the offsetting  gains and  losses of  hedged assets  and
        liabilities are  realized and  recognized.   The fair  values of  the
        forward contracts are included in  the corresponding captions of  the
        hedged  assets  and  liabilities.    Gains  and  losses  on   forward

                                     9<PAGE>
                                      


        contracts, to  the  extent they  differ  in amount  from  the  hedged
        receivables and payables, are included in interest and other income.

          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

             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 which are included in the earnings per share computation
        under the  treasury stock  method.   Put  warrants on  the  Company's
        common stock may also be dilutive and included in earnings per  share
        under the reverse treasury stock method.

             In February 1997, SFAS No. 128, "Earnings Per Share" was  issued
        and is required to be  adopted on December 31,  1997.  At that  time,
        the Company will be required to  change the method currently used  to
        compute earnings per share and to  restate all prior periods.   Under
        the new requirements,  primary and fully  diluted earnings per  share
        will be replaced with  basic and diluted earnings  per share.   Basic
        earnings per share excludes the dilutive effect of stock options  and
        will therefore  be higher  than primary  earnings per  share.   Basic
        earnings per share for the three and nine months ended September  30,
        1997 were $.32 and $1.75, respectively.  Basic earnings per share for
        the three and  nine months  ended September  30, 1996  were $.68  and
        $1.89, respectively.    Diluted  earnings per  share  under  the  new
        standard is expected to be essentially  the same as primary  earnings
        per share amounts calculated under principles currently used.

          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, 1997 and 1996 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.

          Reclassification

             Certain prior period amounts  have been reclassified to  conform
        to the current period presentation.



        2.   Debt

             During the nine  months ended  September 30,  1997, the  Company
        repaid $118.2 million of maturing debt consisting of $68.2 million of
        promissory notes and $50 million of debt securities.

             Long-term debt consists of the following (in millions):

                                          September 30, December 31,

                                             ======        ======

             At September 30, 1997, the Company had $159 million of unsecured
        debt outstanding.  Of  this total, $100  million are debt  securities
        which bear interest at a  fixed rate of 8.1%  and mature on April  1,
        2097.  These debt securities may be  redeemed in whole or in part  at
        the Company's option at any time for a redemption price equal to  the
        greater of the  principal amount  to be redeemed  or the  sum of  the
        present values  of  the  principal and  remaining  interest  payments
        discounted at a determined rate plus, in each case, accrued interest.
        These  securities  place  limitations  on  liens  and  sale/leaseback
        transactions.   The remaining  $59 million  of debt  securities  bear
        interest at fixed  rates averaging 5.8%  and mature in  approximately
        one to six years.

             At September  30, 1997,  $150 million  was available  under  the
        Company's line of credit for borrowing  and to support the  Company's
        commercial paper program.  No borrowings on this line of credit  were
        outstanding at September 30, 1997.

             The decrease in the  effective tax rate in  the current year  is
        primarily the  result  of reduced  pretax  income due  to  the  legal
        assessment recorded  in  the  third quarter  of  1997  (see  Note  4,
        "Contingencies  -  Johnson   &  Johnson   arbitrations")  without   a
        corresponding reduction  in  tax  benefits related  to  Puerto  Rican
        operations.   The  current year  tax  rate also  benefited  from  the
        extension of  the federal  research  and experimentation  tax  credit
        enacted during  the third  quarter  of 1997.    Tax rates  have  been
        reduced during  the last  five quarters  due  to a  favorable  ruling
        received  in  the  third  quarter  of  1996  from  the  Puerto  Rican
        government with respect to tollgate  taxes applicable to earnings  in
        Puerto Rico.


        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").

             A dispute  between  Amgen and  Johnson  & Johnson  that  is  the
        subject of  a 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  in  the Company's  and  Johnson  &  Johnson's
        respective exclusive markets.  In March 1996, an arbitration  hearing
        commenced regarding  the  audit methodologies  and  compensation  for
        sales by  Johnson  &  Johnson into  the  Company's  exclusive  market
                                    12<PAGE>
                                      


        (dialysis)  and  sales  by  the  Company  into  Johnson  &  Johnson's
        exclusive market (non-dialysis).  Spillover occurs when a hospital or
        other purchaser buys  one brand  for use  in both  dialysis and  non-
        dialysis.  On September 12, 1997, the arbitrator in this matter  (the
        "Arbitrator")  issued  an  opinion   adopting  the  Company's   audit
        methodology.  For the  free standing dialysis  center segment of  the
        Epoetin alfa  market,  which accounts  for  about two-thirds  of  the
        Company's EPOGEN sales, the Arbitrator ruled that the Company's audit
        accurately determined that  all Epoetin alfa  sales to free  standing
        dialysis centers are made  for dialysis.  For  the other segments  of
        the Epoetin  alfa  market, the  Arbitrator  ruled that  the  detailed
        methodology used by Amgen  accurately measured and allocated  Epoetin
        alfa sales for all  but the Hospital and  Home Health Care  segments,
        for which he ordered certain adjustments to the results of the  audit
        for the specified time  periods.  The Arbitrator  also ruled that  no
        payments are due for the 1989-90 period.  Subject to further guidance
        from the Arbitrator  to clarify  his opinion,  the Company  estimated
        that the effect of  the opinion would be  a net spillover payment  to
        Johnson & Johnson which, after benefit of income tax effects, was $78
        million for the  1991-94 period  and interest  in the  amount of  $18
        million after tax.  As a result  of the opinion,  the Company took  a
        charge in its third quarter for the spillover payment and interest of
        $0.35 per share.

             Johnson & Johnson asserted  that the Company  owes more for  the
        1991-94 period than the Company calculated for that period. A hearing
        before the Arbitrator was held on October 27, 1997 to clarify,  among
        other issues, the calculation for the amount of the spillover payment
        due to Johnson & Johnson for the 1991-94 time period.  As a result of
        that hearing, the Company will pay an additional amount to Johnson  &
        Johnson for the 1991-94 period which is covered by amounts previously
        provided  for  by  the  Company.    Further  rulings  clarifying  the
        Company's entitlement to attorney's fees and costs and audit costs as
        well as the calculation  of spillover payments, if  any, that may  be
        due to the Company or Johnson & Johnson for 1995, 1996 and 1997  will
        be sought by  the parties before  a final order  is issued.   Pending
        determination by  the  Arbitrator,  the Company  has  not  taken  any
        benefit for the  possible recovery of  attorneys' fees  and costs  or
        audit costs and has retained spillover  reserves.  Johnson &  Johnson
        also  disputes  the  Company's   entitlement  to  reimbursement   for
        attorneys' fees and costs or audit costs.  Accordingly, there can  be
        no assurance that the Arbitrator will award such reimbursement.

             If, as  a  result  of these  further  arbitration  rulings,  any
        adjustments to the results of the Company's audit yield results  that
        are different from the results of the audit currently employed by the
        Company, the Company may be  required to pay additional  compensation
        to Johnson & Johnson for sales during 1995, 1996 and 1997, or Johnson
        & Johnson may be required to pay compensation to the Company for such
        prior period sales.

             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.   Johnson  &  Johnson
        disputes Arbitrator  McGarr's jurisdiction  to decide  the  Company's
        demand.  A hearing before Arbitrator  McGarr on the Company's  demand
                                    13<PAGE>
                                      


        will  be   scheduled  following   his  adjudication   of  the   audit
        methodologies for Epoetin alfa sales.

             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.    On October  27,  1995,  the
        Company filed  a  complaint in  the  Circuit Court  of  Cook  County,
        Illinois seeking an order compelling  Johnson & Johnson to  arbitrate
        the Company's claim for termination before Arbitrator McGarr as  well
        as all related counterclaims asserted in Johnson & Johnson's  October
        2, 1995 AAA arbitration demand.  The Company is unable to predict  at
        this time the outcome of the  demand for termination or when it  will
        be resolved.    The  Company has  filed  a  motion to  stay  the  AAA
        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 counter claiming for certain unpaid invoices.

             On June  5,  1997, Ortho  Biotech,  Inc., a  Johnson  &  Johnson
        affiliate,  filed a demand for arbitration against Kirin-Amgen,  Inc.
        ("Kirin-Amgen"), before the American Arbitration Association ("AAA").
        The demand  alleges  that Amgen's  novel  erythropoiesis  stimulating
        protein ("NESP") is covered  by a license  granted by Kirin-Amgen  to
        Ortho  Pharmaceutical  Corporation  in  1985  for  the   development,
        manufacture and sale of Epoetin  alfa in certain territories  outside
        the United States,  Japan and China.   In  1996 Kirin-Amgen  acquired
        exclusive worldwide rights in NESP from Amgen.  Kirin-Amgen, in turn,
        transferred certain rights  in NESP to  Kirin and  certain rights  to
        Amgen.   Ortho  Biotech  alleges  that  Ortho  Pharmaceutical's  1985
        license agreement with Kirin-Amgen  effectively grants Ortho  Biotech
        the same right to develop, manufacture  and sell NESP as  Kirin-Amgen
        previously  granted  to   Ortho  Pharmaceutical  in   1985  for   the
        development, manufacture and sale of Epoetin alfa.  On June 20,  1997
        Kirin-Amgen initiated  suit  in the  Circuit  Court of  Cook  County,
        Illinois seeking a judicial determination of Ortho Biotech's standing
        to seek  arbitration  of  claims  under  Kirin-Amgen's  1985  license
        agreement with Ortho Pharmaceutical.  At the same time,   Kirin-Amgen
        filed a motion with  AAA to dismiss or  stay the arbitration  pending
        judicial resolution of Ortho  Biotech's standing to arbitrate  claims
        under Kirin-Amgen's  license agreement with Ortho Pharmaceutical.

          Synergen ANTRIL(TM) litigation

             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  the partnership  with  which  Amgen
        Boulder Inc. is  affiliated, has been  certified as  a class  action.
                                    14<PAGE>
                                      


        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.   In  August and  September  1996,  the
        parties filed cross-motions for summary  judgement.  The Court  heard
        argument  on   November  1,   1996.     Since  then,   the   parties'
        representatives have reached a  tentative settlement agreement  which
        is subject to  final approval by  the Court and  the approval of  the
        limited  partners  of  the  partnership.     Under  its  terms,   the
        plaintiffs, who include present limited partners of the  partnership,
        will receive $14.5 million in exchange for the transfer of  ownership
        of their units;  the suit will  be dismissed with  prejudice and  the
        parties will exchange mutual releases.

          FoxMeyer Health Corporation

             On January 10, 1997, FoxMeyer  Health Corporation, now known  as
        Avatex Corporation ("Avatex"), filed suit (the "FoxMeyer Lawsuit") in
        the District Court  of Dallas  County, Dallas,  Texas, alleging  that
        defendant McKesson Corporation ("McKesson") defrauded Avatex, misused
        confidential information received from  Avatex about subsidiaries  of
        Avatex  (FoxMeyer   Corporation   and  FoxMeyer   Drug   Corporation,
        collectively  the   "FoxMeyer   Subsidiaries"),  and   attempted   to
        monopolize the  market for  pharmaceutical  and health  care  product
        distribution  by  attempting  to  injure  or  destroy  the   FoxMeyer
        Subsidiaries.  The Company  is  named as one of twelve  "Manufacturer
        Defendants" alleged to  have conspired with  McKesson Corporation  in
        doing, among  other things,  the above  and  (i) inducing  Avatex  to
        refrain from  seeking  other  suitable purchasers  for  the  FoxMeyer
        Subsidiaries and (ii)  causing Avatex  to believe  that McKesson  was
        serious about  purchasing Avatex's  assets at  fair value,  when,  in
        fact, McKesson was not.  The Manufacturer Defendants and McKesson are
        also alleged to have intentionally  and tortiously interfered with  a
        number of  business expectancies  and opportunities.   The  complaint
        seeks from  the  Manufacturer Defendants  and  McKesson  compensatory
        damages  of  at  least  $400  million  and  punitive  damages  in  an
        unspecified amount, as  well as Avatex's  costs and attorney's  fees.
        The Company has filed  an answer denying  Avatex's allegations.   The
        matter has  been  transferred  to the  Federal  Bankruptcy  Court  in
        Dallas, Texas  (the  "Texas  Bankruptcy Court").    The  Manufacturer
        Defendants subsequently sought to transfer the matter to the  Federal
        Bankruptcy Court in Delaware (the "Delaware Bankruptcy Court"), where
        the FoxMeyer Subsidiaries'  Chapter 7 bankruptcy  action is  pending.
        The Company is a creditor in  such bankruptcy proceeding.  On  August
        27, 1997, the Texas  Bankruptcy Court denied  the motion to  transfer
        venue to the  Delaware Bankruptcy Court,  but decided  that it  would
        adhere  to  any  decision  made  by  the  Delaware  Bankruptcy  Court
        regarding, among  other  things,  ownership  of  claims  asserted  by
        Avatex,  as  described   below.    McKesson   and  the   Manufacturer
        Defendant's have intervened  in an action  brought by  the Chapter  7
        trustee in the  Delaware Bankruptcy Court  that seeks  to enjoin  the
        FoxMeyer Lawsuit and have moved for partial summary judgment in  that
        proceeding, asserting that  Avatex is not  the owner  of the  alleged
        causes of action.  To date,  no discovery has occurred in either  the
                                    15<PAGE>
                                      


        Texas  Bankruptcy  Court  adversary   proceedings  or  the   Delaware
        Bankruptcy Court adversary proceeding for injunction.


             While it is not possible to predict accurately or determine  the
        eventual outcome  of the  above described  legal matters  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,  1997, the  Company
        repurchased 7.4 million shares of its common stock at a total cost of
        $416.5 million which substantially completed the $450 million  amount
        authorized for 1997 under  its common stock  repurchase program.   In
        October 1997,  the  Board  of Directors  authorized  the  Company  to
        repurchase up to  an additional $1  billion of  common stock  through
        December 31, 1998.  Stock repurchased under the program is retired.


        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,  1997, operations  provided  $665.6
        million of cash compared with $545.7  million during the same  period
        last year.  The Company  had cash,  cash equivalents  and  marketable
        securities of $1,101.7 million at  September 30, 1997, compared  with
        $1,077 million at December 31, 1996.

             Capital expenditures totaled  $292 million for  the nine  months
        ended September 30, 1997, compared with  $167.6 million for the  same
        period a  year ago.  The Company  anticipates spending  approximately
        $350 million to  $400 million on  capital projects  and equipment  to
        expand the Company's global operations in 1997.  Thereafter over  the
        next  few  years,  capital  expenditures  are  expected  to   average
        approximately $350-$450 million per year.

             The Company receives  cash from the  exercise of employee  stock
        options.   During the  nine months  ended September  30, 1997,  stock
        options and their  related tax  benefits provided  $127.6 million  of
        cash compared  with $98.4  million for  the  same 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 primarily to  offset
        the dilutive effect of its employee  stock option and stock  purchase
        plans.  During the nine months ended September 30, 1997, the  Company
        purchased 7.4 million shares of its common stock at a cost of  $416.5
                                    16<PAGE>
                                      


        million compared  with 6.1  million shares  purchased  at a  cost  of
        $346.8 million during the  same period last year.   In October  1997,
        the Board of Directors authorized the Company to repurchase up to  $1
        billion of  common  stock through  December  31, 1998.    During  the
        remainder of 1997, the Company expects  to complete the $450  million
        previously authorized for 1997 repurchases  and to utilize a  portion
        of the additional $1 billion  recently authorized for the  repurchase
        program.

             During the nine  months ended  September 30,  1997, the  Company
        repaid $118.2 million of maturing debt consisting of $68.2 million of
        promissory notes and $50  million of debt  securities.  At  September
        30, 1997, the Company had $159 million of unsecured debt outstanding.
        Of this total, $59  million bears interest  at fixed rates  averaging
        5.8% and matures in approximately one  to six years.  In April  1997,
        the Company  issued  $100  million  of  debt  securities  which  bear
        interest at a fixed rate of 8.1% and mature on April 1, 2097.   These
        debt securities were issued to refinance  a portion of debt that  has
        matured in 1997.

             The Company  also has  sources of  debt  financing in  order  to
        provide for  financial  flexibility  and increased  liquidity.    The
        Company has a commercial paper program which provides for  short-term
        borrowings up  to an  aggregate face  amount of  $200 million.    The
        Company also  has  a  $150  million  revolving  line  of  credit  for
        borrowings and  to  support the  commercial  paper program.    As  of
        September 30, 1997, no amounts were outstanding under either source.

             The primary objectives  for the  Company's investment  portfolio
        are liquidity  and safety  of principal.    Investments are  made  to
        achieve the highest rate  of return to  the Company, consistent  with
        these  two  objectives.    The  Company's  investment  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 Company invests
        its excess  cash  in  securities  with  varying  maturities  to  meet
        projected cash needs.

             The Company believes  that existing funds,  cash generated  from
        operations and existing  sources of  debt financing  are adequate  to
        satisfy its working capital and capital expenditure requirements  for
        the foreseeable future.   However, the  Company may raise  additional
        capital from time to time.

        Results of Operations

          Product sales

             Product sales increased 4% and 8% for the three and nine  months
        ended September  30,  1997,  respectively,  compared  with  the  same
        periods last year.

             NEUPOGEN(R) (Filgrastim)

             Worldwide NEUPOGEN(R)  sales  were  $267.9  million  and  $784.1
        million for  the three  and nine  months  ended September  30,  1997,
                                    17<PAGE>
                                      


        respectively.  These amounts represent increases of $9.1 million  and
        $37.8 million or 4% and 5%, respectively, over the same periods  last
        year.  These  increases are primarily  due to  demand growth,  higher
        prices and  the  favorable  effects of  wholesaler  buying  patterns.
        Unfavorable  foreign  currency  effects  and  European  Union  ("EU")
        government initiatives  to  lower health  care  expenditures  reduced
        growth in EU sales.  In  addition, the Company believes that the  use
        of protease inhibitors as a treatment  for AIDS has reduced sales  of
        NEUPOGEN(R) for  off-label  use  as  a  supportive  therapy  in  this
        setting.   NEUPOGEN(R) is  not approved  or  promoted for  such  use,
        except in Australia and Canada.

             Quarterly NEUPOGEN(R)  sales  volume  in the  United  States  is
        influenced by a  number of  factors including  underlying demand  and
        wholesaler inventory  management  practices.    Wholesaler  inventory
        reductions tend to  reduce domestic  NEUPOGEN(R) sales  in the  first
        quarter each year.   In addition, the  discretionary aspects of  some
        cancer chemotherapy administration has  had a slight seasonal  effect
        on NEUPOGEN(R) sales.

             Cost containment pressures in  the health care marketplace  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.

             The growth of  the colony stimulating  factor ("CSF") market  in
        the EU in which NEUPOGEN(R) competes  has slowed, principally due  to
        EU  government  pressures  on  physician  prescribing  practices   in
        response to  on-going government  initiatives to  reduce health  care
        expenditures.   Additionally,  the  Company  faces  competition  from
        another granulocyte CSF product.   Although the Company's CSF  market
        share in  the  EU has  remained  relatively constant  over  the  last
        several  quarters,  the  Company  does  not  expect  the  competitive
        intensity to subside in the near future.

             EPOGEN(R) (Epoetin alfa)

             EPOGEN(R) sales were $284.9 million  and $871.4 million for  the
        three and nine months ended September 30, 1997, respectively.   These
        amounts represent increases of $10.4 million and $88.6 million or  4%
        and 11%, respectively, over the same periods last year.  For the nine
        months ended September 30,  1997, the increase  was primarily due  to
        continued  increases  in  the   U.S.  dialysis  patient   population.
        Although  sales  for  the  three  months  ended  September  30,  1997
        benefited from  increases in  the U.S.  dialysis patient  population,
        EPOGEN(R) sales during this period continued to be adversely affected
        by reimbursement  changes implemented  on September  1, 1997  by  the
        Health Care Finance Administration ("HCFA").  Prior to these changes,
        Fiscal Intermediaries under contract to  HCFA were authorized to  pay
        reimbursement claims for  patients whose hematocrits  were above  the
        FDA approved level of 36 percent with adequate medical justification.
        Under the new rules, medical justification will no longer be accepted
        for payment of  claims above 36  percent, and  reimbursement will  be
        denied if  the current  month's hematocrit  is 36  or above  and  the
        patient's hematocrit  exceeds 36.5  percent on  an historical  90-day
        "rolling average"  basis.   It  has  been and  remains  difficult  to
                                    18<PAGE>
                                      


        predict EPOGEN(R) usage under this policy because individual  patient
        hematocrit variability is  high, the  timing and  nature of  dialysis
        center actions varies widely, and the twice postponed  implementation
        date has  lengthened  the  duration  of  the  implementation  period.
        Beginning in the second quarter of 1997, the Company experienced  and
        continues to experience an impact on  EPOGEN(R) sales of lowered  and
        withheld  doses  as  some   dialysis  providers  attempt  to   reduce
        hematocrits to avoid or minimize future  claim denials.  The  Company
        anticipates that because patient  hematocrits can vary  significantly
        from month to month, physicians  will continue to administer  lowered
        doses and withhold doses to maintain hematocrits at a level which, in
        their judgment,  is  sufficiently  low to  avoid  or  minimize  claim
        denials.  Amgen is aggressively providing information and guidance to
        dialysis providers on  changes in  their practices  to both  maximize
        patient outcomes to the greatest extent  permitted by the new  policy
        and to avoid or  minimize the potential that  claims will be  denied.
        It is not possible to predict which practices will be adopted by each
        dialysis center or when they will do so.

          Corporate partner revenues

             Corporate partner revenues increased  by $7.7 million and  $11.3
        million, or  33% and  13%, during  the three  and nine  months  ended
        September 30, 1997, respectively, compared with the same periods last
        year.  These increases are primarily  due to increased revenues  from
        Yamanouchi Pharmaceutical Co., Ltd.

          Cost of sales

             Cost of sales  as a percentage  of product sales  was 13.4%  and
        13.5% for  the  three  and nine  months  ended  September  30,  1997,
        respectively, compared to 13.7% and 13.6%  for the same periods  last
        year.  In 1997,  cost of sales  as a percentage  of product sales  is
        expected to range from 13%-14% reflecting continuing efficiencies  of
        the Puerto Rican operations.

          Research and development

             During the  three  and nine  months  ended September  30,  1997,
        research and development expenses  increased $42.2 million and  $81.1
        million, or 32% and 21%, respectively, compared with the same periods
        last year.  These increases are primarily due to higher clinical  and
        pre-clinical activities, including staff-related expenses,  necessary
        to support ongoing product development  activities, and in the  third
        quarter  of  1997,  a  $15   million  initial  payment  to   Guilford
        Pharmaceuticals pursuant to a licensing agreement.  In 1997, research
        and development expenses are expected to increase at a rate exceeding
        the Company's product sales  growth rate.   This increase is  planned
        for internal  efforts  on  development  of  product  candidates,  for
        discovery, and for licensing efforts.

          Marketing and selling/General and administrative

             Marketing and selling  expenses decreased $3.2  million, or  4%,
        and increased $0.6 million, or 0.3%, during the three and nine months
        ended September  30,  1997,  respectively,  compared  with  the  same
                                    19<PAGE>
                                      


        periods last year.  The three  and nine month periods both  benefited
        from lower European marketing  expenses resulting from the  favorable
        effects of foreign currency exchange rates and lower expenses related
        to  the  Johnson  &  Johnson  arbitration.    These  reductions  were
        partially or fully  offset by higher  staff-related costs and  higher
        outside marketing expenses.

             General and administrative expenses  increased $4.1 million  and
        $15.2 million, or  10% and 13%,  respectively, during  the three  and
        nine months ended September 30, 1997  compared with the same  periods
        last year.   These  increases were  primarily  due to  higher  staff-
        related expenses.

             In 1997, 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 due in part to the favorable impact of foreign currency exchange
        rates on  European  expenses  and reduced  expenses  related  to  the
        Johnson & Johnson arbitration.

          Legal assessment

             During the three  months ended September  30, 1997, the  Company
        recorded a pre-tax  charge of $157  million relating  to a  spillover
        arbitration award to Johnson & Johnson.  See Note 4 to the  Condensed
        Consolidated Financial Statements - "Johnson & Johnson arbitrations".

          Interest and other income

             Interest and  other  income  increased  $0.7  million  and  $3.4
        million, or 4% and 7%, respectively, during the three and nine months
        ended September 30, 1997  compared with the  same periods last  year.
        The increases are principally due to higher income from the Company's
        investment  portfolio  and  gains  on  foreign  currency  denominated
        contracts,  and  are  partially   offset  by  certain   non-operating
        expenses.  Interest and  other income is  expected to fluctuate  from
        period to  period  primarily due  to  changes in  cash  balances  and
        interest rates.

          Income taxes

             The Company's effective tax rates for the three and nine  months
        ended September 30,  1997 was 5.1%  and 24.7% compared  with 28%  and
        29.8%, respectively, for the same periods last year.  These decreases
        are primarily the result  of reduced pretax income  due to the  legal
        assessment recorded  in  the  third  quarter  of  1997  (see "--Legal
        assessment")  without  a  corresponding  reduction  in  tax  benefits
        related to Puerto Rican operations.   The rates for the 1997  periods
        also benefited  from  the  extension  of  the  federal  research  and
        experimentation tax credit enacted during the third quarter of  1997.
        Tax rates have been  reduced during the last  five quarters due to  a
        favorable ruling  received in  the third  quarter  of 1996  from  the
        Puerto Rican government with respect to tollgate taxes applicable  to
        earnings in Puerto Rico.  In  1998, the Company expects the tax  rate
        to increase to approximately 30%, due to a change in the U.S. federal

                                    20<PAGE>
                                      


        tax law which  limits the tax  benefits related  to manufacturing  in
        Puerto Rico, the location of the Company's fill-and-finish facility.

          Foreign currency transactions

             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
        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, 1997, outstanding  foreign currency option and  forward
        contracts totaled $49.1 million and $78.1 million, respectively.

        Financial Outlook

             Worldwide NEUPOGEN(R) (Filgrastim) sales  for 1997 are  expected
        to grow  at  a  rate  lower  than  the  1996  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.  Although not approved  or promoted for use  in
        Amgen's domestic or foreign markets, except for Australia and Canada,
        the  Company  believes  that  approximately  10%  of  its   worldwide
        NEUPOGEN(R) sales are from off-label use  as a supportive therapy  to
        various AIDS  treatments.    Changes  in  AIDS  therapies,  including
        therapies that may  be less  myelosuppressive, are  believed to  have
        adversely affected and are expected  to continue to adversely  affect
        such sales.  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 changes in foreign currency exchange rates and government budgets.

             The Company  anticipates a  single-digit sales  growth rate  for
        EPOGEN(R) (Epoetin alfa) in 1997.  The Company also anticipates that,
        without any modifications to the reimbursement changes implemented by
        HCFA, additional sales growth  due to dose, if  any, is likely to  be
        minimal; however, the  Company believes  that increases  in the  U.S.
        dialysis patient population will continue to grow EPOGEN(R) sales  in
        the near  term.   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  is aware  of
        reports that a draft report by the Inspector General recommends a 10%
        cut in Medicare reimbursement for EPOGEN.  The Company believes  that
        the Inspector General's  report is  now in  a period  of comment  and
        cannot predict when a final recommendation will be publicly issued.

             In  October  1997,  the  Company  launched  its  third  product,
        INFERGEN(R) (Interferon  alfacon-1),  for the  treatment  of  chronic
        Hepatitis C  Virus infection.   There  are currently  other  existing
        treatments for this infection against which INFERGEN(R) will compete.
        The Company cannot predict the extent to which it will penetrate this
        market.   The  Company is  presently  engaged in  certain  litigation
                                    21<PAGE>
                                      


        related to INFERGEN(R), as described in  the Company's Form 10-K  for
        fiscal year ended December 31, 1996 and the quarterly reports on Form
        10-Q for the quarters ended March 31, 1997 and June 30, 1997.

             The Company  anticipates  a  single digit  total  product  sales
        growth rate  for  1997.   Excluding  the  third  quarter  1997  legal
        assessment, earnings per share  is expected to grow  at a low  double
        digit rate in 1997.  Estimates of future  product sales and  earnings
        per share, however,  are necessarily  speculative in  nature and  are
        difficult to predict with accuracy.

             In the third quarter of 1997,  the Company announced that it  is
        seeking a corporate partner for its ongoing inflammation research and
        development program located in Boulder, Colorado, which includes  the
        product candidates IL-1ra (interleukin-1 receptor antagonist),  TNFbp
        (tumor necrosis factor binding protein) and SLPI (secretory leukocyte
        protease inhibitor).   However, there can  be no  assurance that  the
        Company will be successful in finding an acceptable corporate partner
        or acceptable business terms.

             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

        Discussion  and  Analysis  of  Financial  Condition  and  Results  of
        Operations--Factors That May Affect Future Results" in the  Company's
        Annual Report on  Form 10-K  for the  year ended  December 31,  1996,

        Legal Matters

             The Company is  engaged in arbitration  proceedings with one  of
        its licensees and various other legal proceedings.  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,  1996,
        with  material  developments  since  that  report  described  in  the
        Company's Form 10-Q for  the quarters ended March  31, 1997 and  June
        30, 1997 and below.  While  it is not possible to predict  accurately
                                    22<PAGE>
                                      


        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.

          Biogen litigation

             On March 10,  1995, Biogen Inc.  ("Biogen"), filed  suit in  the
        United States  District  Court  for  the  District  of  Massachusetts
        alleging infringement by the Company of certain claims of U.S. Patent
        4,874,702 (the  "`702 Patent"),  relating to  vectors for  expressing
        cloned genes.  Biogen alleges that Amgen has infringed its patent  by
        manufacturing and selling  NEUPOGEN(R).   On March  28, 1995,  Biogen
        filed an amended complaint further alleging that the Company is  also
        infringing the claims of two additional patents allegedly assigned to
        Biogen, U.S. Patent 5,401,642 (the "`642 Patent") and U.S. Patent No.
        5,401,658 (the  "`658  Patent"),  relating to  vectors,  methods  for
        making vectors and  expressing closed genes.   The amended  complaint
        seeks injunctive relief, unspecified compensatory damages and  treble
        damages.  On April  24, 1995, the  Company answered Biogen's  amended
        complaint,   denying   its   material   allegations   and    pleading
        counterclaims for  declaratory judgment  of non-infringement,  patent
        invalidity and  unenforceability.   On January  19, 1996,  the  Court
        decided,  upon  Biogen's  motion   to  dismiss  certain  of   Amgen's
        counterclaims, that it will exert jurisdiction  over claims 9 and  17
        of the  `702  Patent,  and dismissed  all  claims  and  counterclaims
        relating to any  other claims of  the `702 Patent.   Amgen moved  for
        Summary Judgment of  invalidity of claim  9 of the  `702 Patent.   On
        July 7, 1997, the Company's Summary  Judgment Motion was denied.   On
        August 14,  1997, Amgen  filed a  Motion for  Reconsideration of  the
        Courts ruling  on invalidity  of claim  9  of the  `702 patent.    On
        October 20, 1997,  the Motion  for Reconsideration  was also  denied.
        These denials are not dispositive of the case, and the effect of  the
        ruling is to reserve certain issues for trial.  On October 22,  1997,
        Amgen moved for summary judgment of invalidity of the certain  claims
        of the  `702 and  `651 Patents  based  on prior  public uses  of  the
        claimed subject  matter.   Amgen  concurrently  moved for  a  partial
        interpretation of the claims at issue.   In addition, on October  24,
        1997, Amgen  filed a  motion for  summary judgment  of invalidity  of
        particular claims of the patents-in-suit based on abandonment of  the
        invention.  Amgen  also concurrently filed  a motion  to dismiss  the
        lawsuit in its entirety based on  Biogen's lack of standing to  bring
        the lawsuit in view of Biogen's lack of ownership of the  patents-in-
        suit.  Discovery  in the case  is substantially completed.   A  trial
        date has not been set.

             In a separate matter, on July 30, 1997, Biogen filed a complaint
        in the United States District Court for the District of Massachusetts
        in Boston alleging that Amgen infringes  claims 9 and 17 of the  `702
        Patent, and the `642 Patent and  `658 Patent by making and using  the
        claimed subject matter  in the United  States in  the manufacture  of
        INFERGEN(R),  the  Company's  consensus   interferon  product.     On
        September 17,  1997, Amgen  responded to  the Complaint  by filing  a
        motion to dismiss the  case in its entirety  due to Biogen's lack  of
        standing to bring the lawsuit in  view of Biogen's lack of  ownership
        of the  patents-in-suit.   Amgen  also  filed a  motion  for  summary
        judgment of patent invalidity of particular claims of the patents-in-
                                    23<PAGE>
                                      


        suit due  to abandonment  of the  invention.   Biogen is  seeking  to
        consolidate  this  case  with  above-described  case  pertaining   to
        NEUPOGEN(R).  Discovery has not begun  and a trial date has not  been
        set.

          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 ( the "'362, `619 and  `832 Patents"), 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).  On  December 2, 1996,  Amgen
        was served  with this  lawsuit.   On January  21, 1997,  the  Company
        answered  the  complaint  and  asserted  counterclaims  relating   to
        invalidity and non-infringement of the patents-in-suit.  On  February
        10,  1997,  Genentech,  Inc.  served  Amgen  with  a  reply  to   the
        counterclaim and  an additional  counterclaim asserting  U.S.  Patent
        5,583,013 (the  "'013 Patent"),  issued  December 10,  1996,  seeking
        relief similar to that  sought for the '362,  `619 and `832  Patents.
        On  March  31,  1997,  Amgen  answered  this  pleading  and  asserted
        counterclaims relating to invalidity and non-infringement of the `013
        Patent.  Discovery  is currently  ongoing.   The parties  are in  the
        process of  exchanging papers  pertaining  to interpretation  of  the
        patent  claims.    A  "Markman  hearing"  on  claim  construction  is
        scheduled for March 1998.

                       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<PAGE>
                                        


            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<PAGE>





            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<PAGE>
                                        


                 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.
