    pursuant to Rule 457(o) under the Securities Act of 1933, as amended (the

    Prior to the occurrence of certain events, the Series A Junior
    Participating Preferred Stock purchase rights will not be exercisable or

    (b) the liquidation preference, or, if different, the initial offering
    price of any preferred shares, (c) the principal amount of the debt
    securities, and the issue price rather than the principal amount of any
    such securities listed at original issue discount, (d) the initial
    offering price of any warrants or depositary shares, (e) the purchase
    price of any common or preferred shares under any stock purchase contract,
    and (f) the initial offering price of any stock purchase units.

                           FORWARD-LOOKING STATEMENTS

     This prospectus,  the prospectus supplement,  the documents incorporated by
reference in this  prospectus and other written reports and oral statements made
from time to time by the company may contain "forward-looking statements" within
the  meaning  of  the  Private   Securities   Litigation  Reform  Act  of  1995.
Forward-looking statements relate to expectations or forecasts of future events.
They use words such as "anticipate,"  "believe," "could," "estimate,"  "expect,"
"forecast,"  "project,"  "intend," "plan,"  "potential," "will," and other words
and terms of similar meaning in connection with a discussion of potential future
events, circumstances or future operating or financial performance. You can also
identify forward-looking statements by the fact that they do not relate strictly
to historical or current facts.

     In particular,  forward-looking  statements include statements  relating to
future actions, ability to access the capital markets, prospective products, the
status of product  approvals,  future  performance  or  results  of current  and
anticipated products, sales efforts, development programs, expenses and programs
to reduce  expenses,  the cost of and savings from reductions in work force, the
outcome of contingencies such as litigation and investigations,  growth strategy
and financial results.

     Any or all of our forward-looking  statements here or in other publications
may turn out to be wrong.  Our actual  results  may vary  materially  from those
anticipated in such  forward-looking  statements as a result of several factors,
some of which are more fully  described in the following  "Risk Factor"  section
and in the  accompanying  prospectus  supplement  and  our  reports  to the  SEC
incorporated  by reference  into this  prospectus,  and there are no  guarantees
about the performance of the company. The company does not assume the obligation
to update any forward-looking statement for any reason.

                                  RISK FACTORS

     Our  business  faces  significant  risks.  Before  you invest in any of our
securities,  in addition to the other  information in this prospectus and in the
accompanying prospectus supplement,  you should carefully consider the risks and
uncertainties  described  in the  accompanying  prospectus  supplement  and  our
reports  to the SEC  incorporated  by  reference  into this  prospectus  and the
accompanying  prospectus  supplement,  including  the  risks  and  uncertainties
identified  under the "Legal,  Environmental  and Regulatory  Matters"  footnote
included  in  the  financial  statements,  and  under  the  captions  "Executive
Summary,"   "Additional   Factors   Influencing    Operations,"   "Market   Risk
Disclosures,"  and  "Cautionary  Factors that May Affect Future  Results" in the
"Management's  Discussion  and  Analysis of Financial  Condition  and Results of
Operation"  section,  in each case, in our quarterly report on Form 10-Q for the
quarter  ended  March  31,  2004  and  in our  subsequent  reports  to  the  SEC
incorporated by reference into this prospectus and the  accompanying  prospectus
supplement,  as the same may be updated from time to time, and under the caption
"Item 1.  Business,"  in our  annual  report  on Form  10-K  for the year  ended
December  31,  2003 and in our  subsequent  reports to the SEC  incorporated  by
reference into this prospectus and the accompanying  prospectus  supplement,  as
the same may be updated from time to time. These risks may not be the only risks
we  face.  Additional  risks  that  we do not yet  know of or that we  currently
believe are immaterial or are based on assumptions  that are later determined to
be inaccurate also may impair our business. If any of the risks described in the
accompanying


                                       7



prospectus supplement or our reports to the SEC actually occur, our business and
operating results could be materially harmed.  This could cause the value of the
purchased  securities  to  decline,  and  you  may  lose  all or  part  of  your
investment.

                      RATIO OF EARNINGS TO FIXED CHARGES

     Our  consolidated  ratio of earnings to fixed charges for the three months
ended March 31, 2004 and for each of the fiscal  years ended  December  31, 1999
through 2003 is set forth  below.  For the purpose of  computing  these  ratios,
"earnings"  consist of income  (loss) before income taxes and equity income from
our cholesterol  joint venture with Merck & Co., Inc., plus fixed charges (other
than capitalized interest) and distributed income from the joint venture. "Fixed
charges"  consist of interest  expense,  capitalized  interest and  one-third of
rentals which we believe to be a reasonable  estimate of the interest  component
within leases. The ratio was calculated by dividing the sum of the fixed charges
into the sum of the earnings before taxes and fixed charges.

                                USE OF PROCEEDS

     Unless  the  applicable  prospectus  supplement  indicates  otherwise,   we
currently intend to use the net proceeds from any sale of the offered securities
for  general  corporate  purposes,   which  may  include,  among  other  things,
refinancing  of short-term  debt or commercial  paper,  the funding of operating
expenses,  capital  expenditures,  licensing fees and milestone payments and the
payment of settlement  amounts,  fines,  penalties and other  investigatory  and
litigation  costs and  expenses.  We may  temporarily  invest funds that are not
immediately needed for these general corporate purposes. If we intend to use the
proceeds to repay  outstanding debt, we will provide details about the debt that
is being repaid in the applicable prospectus supplement.

                         DESCRIPTION OF DEBT SECURITIES

     This section  contains a description of the general terms and provisions of
the debt securities that may be offered by this prospectus.  We may issue senior
debt securities and subordinated  debt  securities.  The debt securities will be
issued in one or more series  under an  indenture  to be entered into between us
and The Bank of New York, as trustee.  The indenture  may be  supplemented  from
time to time.

     This  prospectus  briefly  outlines some of the indenture  provisions.  The
following  summary of the material  provisions  of the indenture is qualified in
its  entirety by the  provisions  of the  indenture,  including  definitions  of
certain terms used in the indenture. Wherever we refer to particular sections or
defined terms of the indenture, those sections or defined terms are incorporated
by reference in this prospectus or prospectus supplement.  You should review the
indenture  that  is  filed  as an  exhibit  to the  registration  statement  for
additional information.

     In addition, the material specific financial, legal and other terms as well
as federal income tax consequences  particular to securities of each series will
be described in the  prospectus  supplement  relating to the  securities of that
series. The prospectus supplement may or may not


                                       10



modify the  general  terms found in this  prospectus  and will be filed with the
SEC.  For a complete  description  of the terms of a  particular  series of debt
securities,  you should read both this prospectus and the prospectus  supplement
relating to that particular series.

GENERAL

     The indenture does not limit the amount of debt that we may issue under the
indenture or otherwise.  Under the indenture, we may issue the securities in one
or more series with the same or various maturities, at par or a premium, or with
original issue  discount.  We may also reopen a previous issue of securities and
issue additional securities of the series.

     The debt securities covered by this prospectus will be our direct unsecured
obligations.  Senior debt  securities will rank equally with our other unsecured
and unsubordinated indebtedness.  Subordinated debt securities will be unsecured
and  subordinated in right of payment to the prior payment in full of all of our
unsecured and senior  indebtedness.  See "--  Subordination"  below.  Any of our
secured indebtedness will rank ahead of the debt securities to the extent of the
assets securing such indebtedness. Also, we conduct operations primarily through
our subsidiaries and  substantially  all of our consolidated  assets are held by
our  subsidiaries.  Accordingly,  our  cash  flow  and our  ability  to meet our
obligations  under the debt securities will be largely dependent on the earnings
of our  subsidiaries  and the distribution or other payment of these earnings to
us in the form of  dividends  or loans or advances  and  repayment  of loans and
advances from us. Our  subsidiaries are separate and distinct legal entities and
have no obligation  to pay the amounts which will be due on our debt  securities
or to make any funds  available  for payment of amounts which will be due on our
debt  securities.  Because we are a holding company,  our obligations  under our
debt  securities  will be  effectively  subordinated  to all existing and future
liabilities of our subsidiaries,  including, for example, the interest rate swap
contracts  described in the  discussion  of cash  management  strategies  in the
"Liquidity  and Financial  Resources"  section of the Annual Report on Form 10-K
for the year ended December 31, 2003.  Therefore,  our rights, and the rights of
our  creditors,  including  the rights of the holders of the debt  securities to
participate in any  distribution of assets of any of our  subsidiaries,  if such
subsidiary were to be liquidated or reorganized,  is subject to the prior claims
of the  subsidiary's  creditors.  To the extent  that we may be a creditor  with
recognized claims against our subsidiaries, our claims will still be effectively
subordinated  to any  security  interest in, or mortgages or other liens on, the
assets of the subsidiary that are senior to us.

     The prospectus  supplement  relating to any series of debt securities being
offered will include  specific terms relating to the offering.  These terms will
include, among other terms, some or all of the following, as applicable:

     o    the title and type of the series of debt securities;

     o    the total principal amount of the series of debt securities;

     o    the percentage of the principal amount at which the series of debt
          securities will be issued and any payments due if the maturity of the
          debt securities is accelerated;


                                       11



     o    the date or dates on which the principal of the debt securities will
          be payable;

     o    the interest rate or rates, if any, and/or the method of determining
          such interest rate or rates, if any, which the series of debt
          securities will bear;

     o    the date or dates from which any interest will accrue, or the method
          of determining such date or dates, the interest payment date or dates
          for the series of debt securities and the regular record date for any
          interest payable on any interest payment date;

     o    any optional or mandatory redemption periods;

     o    any sinking fund or other provisions that would obligate us to
          repurchase or otherwise redeem the series of debt securities;

     o    whether the series of debt securities will be denominated in, and
          whether the principal of and any premium and any interest on the
          series of debt securities will be payable in, U.S. dollars or any
          foreign currency, currency unit or composite currency;

     o    any index or other special method we will use to determine the amount
          of principal or any premium or interest we will pay on the debt
          securities of the series;

     o    whether the series of debt securities are to be issued in individual
          certificates to each holder or in the form of global securities held
          by a depositary on behalf of holders;

     o    any addition to, or modification or deletion of, any event of default
          or any covenant specified in the indenture;

     o    any special tax implications of the series of debt securities,
          including provisions for original issue discount securities, if
          offered;

     o    any provisions for convertibility or exchangeability of the debt
          securities into or for any other securities;

     o    whether the debt securities are subject to subordination and the terms
          of such subordination; and

     o    any other specific terms of the series of debt securities.

     The prospectus  supplement  relating to a series of debt  securities  being
offered  pursuant  to this  prospectus  will be  attached  to the  front of this
prospectus.

     We may in the future issue debt  securities  other than the debt securities
described  in this  prospectus.  There is no  requirement  that any  other  debt
securities that we issue be issued under


                                       12



the indenture.  Thus, any other debt  securities that we may issue may be issued
under other indentures or  documentation  containing  provisions  different from
those  included in the indenture or applicable to one or more issues of the debt
securities described in this prospectus.

CONSOLIDATION, MERGER OR SALE

     Under the indenture,  we have agreed not to consolidate  with or merge into
any other  corporation or convey or transfer or lease  substantially  all of our
properties and assets to any person, unless:

     o    the person is a corporation or limited liability company organized and
          validly existing under the laws of the United States or any state
          thereof or the District of Columbia;

     o    the successor corporation expressly assumes by a supplemental
          indenture the due and punctual payment of the principal of and any
          premium or any interest on all the debt securities and the performance
          of every covenant in the indenture that we would otherwise have to
          perform as if it were an original party to the indenture;

     o    immediately after giving effect to the consolidation, merger,
          conveyance, transfer or lease, no default or event of default shall
          have occurred and be continuing; and

     o    we deliver to the trustee an officers' certificate and an opinion of
          counsel, each stating that the consolidation, merger, conveyance,
          transfer or lease and the supplemental indenture comply with these
          provisions.

     The  successor  corporation  will  assume  all our  obligations  under  the
indenture as if it were an original party to the  indenture.  After assuming the
obligations, the successor corporation will have all our rights and powers under
the indenture.

LIMITATIONS ON LIENS

     Subject to the exceptions  described  below and those  described  under the
section of this prospectus captioned "Exempted  Indebtedness" below, we may not,
and  may not  permit  any  restricted  subsidiary  to,  create  any  lien on any
principal  property  or shares of  capital  stock of any  restricted  subsidiary
without equally and ratably securing the debt securities.  This restriction will
not apply to permitted liens, including:

     o    liens on principal property existing at the time of its acquisition or
          to secure the payment of all or part of the purchase price;

     o    with respect to any series of debt securities, any lien existing on
          the date of issuance of the debt securities;

     o    liens on property or shares of capital stock, or securing
          indebtedness, of any corporation existing at the time the corporation
          becomes a restricted subsidiary or is merged into us or into a
          restricted subsidiary;


                                       13



     o    liens which secure debt of a restricted security that is owed to us or
          to another subsidiary or our debt that is owed to a restricted
          subsidiary;

     o    liens in connection with the issuance of certain tax-exempt industrial
          development or pollution control bonds or other similar bonds;

     o    liens in favor of any customer arising in respect of payments made by
          or on behalf of a customer for goods produced for, or services
          rendered to, customers in the ordinary course of business not
          exceeding the amount of those payments;

     o    any extension, renewal or replacement of any lien referred to in any
          of the previous paragraphs; and

     o    statutory liens, liens for taxes or assessments or governmental
          charges or levies not yet due or delinquent or which can be paid
          without penalty or are being contested in good faith, landlord's liens
          on leased property, easements and other liens of a similar nature as
          those described above.

LIMITATION ON SALE AND LEASEBACK TRANSACTIONS

     Subject to the exceptions  described  below and those  described  under the
section of this prospectus captioned "Exempted Indebtedness," sale and leaseback
transactions  by us or any restricted  subsidiary of any principal  property are
prohibited  under capital  leases  (except for leases for a term,  including any
renewal  thereof,  of not more than three years and except for leases between us
and a subsidiary or between subsidiaries) unless:

      o     after giving effect to the application of proceeds from the sale and
            leaseback transaction, we or the restricted subsidiary could incur a
            mortgage on the property under the restrictions described above
            under the section of this prospectus captioned "Limitations on
            Liens" in an amount equal to the attributable debt with respect to
            the sale and leaseback transaction without equally and ratably
            securing the debt securities; or

      o     we, within 120 days after the sale or transfer by us or any
            restricted subsidiary, apply to the retirement of our funded debt
            (which is defined as indebtedness for borrowed money having a
            maturity of, or by its terms extendible or renewable for, a period
            of more than 12 months after the date of determination of the
            amount) an amount equal to the greater of:

            (1) the net proceeds of the sale of the principal domestic
                property sold and leased under such arrangement; or

            (2) the fair market value of the principal domestic property
                sold and leased, subject to credits for certain voluntary
                retirements of funded debt.


                                       14



EXEMPTED INDEBTEDNESS

     We or any  restricted  subsidiary  may create or assume liens or enter into
sale and leaseback  transactions  not otherwise  permitted  under the provisions
regarding  limitations  on liens and sale and leaseback  transactions  described
above, so long as at that time and  immediately  after giving effect to the lien
or  sale  and  leaseback  transaction,  the  sum of  our  and  our  consolidated
subsidiaries' aggregate outstanding  indebtedness incurred after the date of the
indenture and secured by the liens  relating to principal  properties  plus that
related to sale and leaseback  transactions  does not exceed 10% of consolidated
net tangible assets.

CERTAIN DEFINITIONS

     The following are the meanings of terms that are important in understanding
the covenants previously described:

     o    "ATTRIBUTABLE DEBT" means the present value (discounted at a specified
          rate each year to be determined by the company to be appropriate and
          consistent with U.S. generally accepted accounting principles) of the
          obligations for rental payments required to be paid during the
          remaining term of any lease of more than 12 months.

     o    "CONSOLIDATED NET TANGIBLE ASSETS" means the total assets of us and
          our consolidated subsidiaries as shown on or reflected in our most
          recent quarterly or annual, as applicable, balance sheet, less (1) all
          current liabilities, excluding current liabilities which could be
          classified as long-term debt under U.S. generally accepted accounting
          principles and current liabilities which are by their terms extendible
          or renewable at the obligor's option to a time more than 12 months
          after the time as of which the amount of current liabilities is being
          computed; (2) advances to entities accounted for on the equity method
          of accounting; and (3) intangible assets. In this context, "intangible
          assets" means the aggregate value, net of any applicable reserves, as
          shown on or reflected in our balance sheet, of (a) all trade names,
          trademarks, licenses, patents, copyrights and goodwill; (b)
          organizational and development costs; (c) deferred charges, other than
          prepaid items such as insurance, taxes, interest, commissions, rents
          and similar items and tangible assets being amortized; and (d)
          unamortized debt discount and expense, less unamortized premium.

     o    "PRINCIPAL PROPERTY" means any manufacturing facility having a gross
          book value in excess of 1% of conSolidated net tangible assets that we
          or any restricted subsidiary owns and located within the United
          States, excluding its territories and possessions and Puerto Rico,
          other than any facility or portion of a facility which our board of
          directors reasonably determines is not material to the business
          conducted by us and our subsidiaries as a whole.

     o    "RESTRICTED SUBSIDIARY" means any subsidiary (1) of which
          substantially all of the property of is located, and substantially all
          of the business is carried on, within the United States, excluding its
          territories and possessions and Puerto Rico; and (2)


                                       15



          which owns or operates one or more principal properties (however,
          "restricted subsidiary" does not include subsidiaries primarily
          engaged in the business of a finance or insurance company and their
          branches).

     o    "SUBSIDIARY" means each corporation of which more than 50% of the
          outstanding voting stock is owned, directly or indirectly, by us or
          one or more of our subsidiaries.

EVENTS OF DEFAULT

     When we use the term  "event of default"  in the  indenture,  here are some
examples of what we mean. An event of default occurs if:

     o    we fail to make the principal or any premium payment on any debt
          security when due;

     o    we fail to pay interest on any debt security for 45 days after payment
          was due;

     o    we fail to make any sinking fund payment when due;

     o    we fail to perform any other covenant in the indenture and this
          failure continues for 90 days after we receive written notice of it;
          or

     o    we or a court take certain actions relating to the bankruptcy,
          insolvency or reorganization of our company.

     The supplemental  indenture or the form of security for a particular series
of debt  securities may include  additional  events of default or changes to the
events of  default  described  above.  The  events of  default  applicable  to a
particular  series  of debt  securities  will  be  discussed  in the  prospectus
supplement  relating to such series. A default under our other indebtedness will
not be a default  under the indenture  for the debt  securities  covered by this
prospectus,  and a  default  under  one  series  of  debt  securities  will  not
necessarily be a default under another  series.  The trustee may withhold notice
to the holders of debt  securities  of any default  (except  for  defaults  that
involve  our  failure  to  pay  principal  or  interest)  if it  considers  such
withholding of notice to be in the best interests of the holders.

     If an event of default with respect to outstanding  debt  securities of any
series occurs and is continuing, then the trustee or the holders of at least 25%
in principal  amount of outstanding  debt securities of that series may declare,
in a written notice, the principal amount (or specified amount) plus accrued and
unpaid  interest on all debt securities of that series to be immediately due and
payable.  At any time after a declaration of  acceleration  with respect to debt
securities  of any series has been made,  the holders of a majority in principal
amount (or specified  amount) of the outstanding debt securities of that series,
by written notice to us and the trustee,  may rescind and annul such declaration
and its consequences if:

     o    we have paid or deposited with the trustee a sum sufficient to pay
          overdue interest and overdue principal other than the accelerated
          interest and principal; and


                                       16



     o    we have cured or the holders have waived all events of default, other
          than the non-payment of accelerated principal and interest with
          respect to debt securities of that series, as provided in the
          indenture.

     We refer you to the  prospectus  supplement  relating to any series of debt
securities that are discount  securities for the particular  provisions relating
to acceleration of a portion of the principal amount of the discount  securities
upon the occurrence of an event of default.

     If a default  in the  performance  or breach of the  indenture  shall  have
occurred and be continuing, the holders of not less than a majority in principal
amount of the  outstanding  securities of all series,  by notice to the trustee,
may waive any past  event of default or its  consequences  under the  indenture.
However,  an event of  default  cannot be waived  with  respect to any series of
securities in the following two circumstances:

     o    a failure to pay the principal of, and premium, if any, or interest on
          any security; or

     o    a covenant or provision that cannot be modified or amended without the
          consent of each holder of outstanding securities of that series.

     Other than its duties in case of a default, the trustee is not obligated to
exercise any of its rights or powers under the  indenture at the request,  order
or  direction of any holders,  unless the holders  offer the trustee  reasonable
indemnity. If they provide this reasonable indemnity,  the holders of a majority
in principal amount outstanding of any series of debt securities may, subject to
certain  limitations,  direct  the  time,  method  and place of  conducting  any
proceeding  or any remedy  available to the  trustee,  or  exercising  any power
conferred upon the trustee, for any series of debt securities.

     We are  required  to deliver to the trustee an annual  statement  as to our
fulfillment of all of our obligations under the indenture.

MODIFICATION OF INDENTURE

     Under the  indenture,  our  rights  and  obligations  and the rights of the
holders may be modified  if the  holders of a majority  in  aggregate  principal
amount  of the  outstanding  debt  securities  of each  series  affected  by the
modification  consent to it.  However,  no  modification of the maturity date or
principal  or interest  payment  terms,  no  modification  of the  currency  for
payment, no impairment of the right to sue for the enforcement of payment at the
maturity of the debt security,  no modification of any conversion  rights and no
modification reducing the percentage required for modifications or modifying the
foregoing  requirements  or reducing the  percentage  required to waive  certain
specified  covenants is  effective  against any holder  without its consent.  In
addition,  no supplemental  indenture  shall adversely  affect the rights of any
holder of senior indebtedness with respect to subordination  without the consent
of such holder.


                                       17



SUBORDINATION

     The extent to which a particular series of subordinated debt securities may
be subordinated  to our unsecured and  unsubordinated  indebtedness  will be set
forth in the prospectus  supplement for any such series and the indenture may be
modified by a supplemental indenture to reflect such subordination provisions.

PAYMENT AND TRANSFER

     We will  pay  principal,  interest  and any  premium  on  fully  registered
securities at the place or places  designated by us for such  purposes.  We will
make payment to the persons in whose names the debt securities are registered on
the close of business  on the day or days  specified  by us. Any other  payments
will be made as set forth in the applicable prospectus supplement.

     Holders  may  transfer  or  exchange  fully  registered  securities  at the
corporate  trust  office  of  the  trustee  or at any  other  office  or  agency
maintained by us for such  purposes,  without the payment of any service  charge
except for any tax or governmental charge.

GLOBAL SECURITIES

     We may issue the  securities in whole or in part in the form of one or more
global  securities  that will be deposited  with,  or on behalf of, a depositary
identified  in the  applicable  prospectus  supplement.  We may issue the global
securities in either registered or bearer form, in either temporary or permanent
form.

     You may  transfer  or  exchange  certificated  securities  at any office we
maintain for this purpose in accordance with the terms of the indenture. We will
not  charge  a  service  fee  for  any  transfer  or  exchange  of  certificated
securities,  but we may require  payment of a sum sufficient to cover any tax or
other  governmental  charge we are required to pay in connection with a transfer
or exchange.

     You may effect the  transfer of  certificated  securities  and the right to
receive the principal,  premium and interest on certificated  securities only by
surrendering  the certificate  representing  those  certificated  securities and
either  reissuance by us or the trustee of the  certificate to the new holder or
the issuance by us or the trustee of a new certificate to the new holder.

     We are not required to:

     o    register, transfer or exchange securities of any series during a
          period beginning at the opening of business 15 days before the day we
          transmit a notice of redemption of securities of the series selected
          for redemption and ending at the close of business on the day of the
          transmission; or

     o    register, transfer or exchange any security so selected for redemption
          in whole or in part, except the unredeemed portion of any security
          being redeemed in part.


                                       18



     The applicable  prospectus  supplement  will describe the specific terms of
the depositary  arrangement  with respect to the  applicable  securities of that
series. We anticipate that the following provisions will apply to all depositary
arrangements.

     Once a global  security  is  issued,  the  depositary  will  credit  on its
book-entry system the respective principal amounts of the individual  securities
represented by that global  security to the accounts of  institutions  that have
accounts with the depositary. These institutions are known as participants.  The
underwriters  for the  securities  will  designate  the accounts to be credited.
However,  if we have offered or sold the securities  either  directly or through
agents, we or the agents will designate the appropriate accounts to be credited.

     Ownership of  beneficial  interest in a global  security will be limited to
participants or persons that may hold beneficial interests through participants.
Ownership of beneficial  interest in a global security will be shown on, and the
transfer of that ownership will be effected only through,  records maintained by
the  depositary's  participants or persons that hold through  participants.  The
laws of some states require that certain  purchasers of securities take physical
delivery  of  securities.  Such  limits  and such laws may limit the  market for
beneficial interests in a global security.

     So long as the depositary  for a global  security,  or its nominee,  is the
registered  owner  of a global  security,  the  depositary  or  nominee  will be
considered the sole owner or holder of the securities  represented by the global
security  for all  purposes  under  the  indenture.  Except as  provided  in the
applicable  prospectus  supplement,  owners of beneficial  interests in a global
security:

     o    will not be entitled to have securities represented by global
          securities registered in their names;

     o    will not receive or be entitled to receive physical delivery of
          securities in definitive form; and

     o    will not be considered owners or holders of these securities under the
          indenture.

     Payments  of  principal,   any  premium  and  interest  on  the  individual
securities  registered in the name of the depositary or its nominee will be made
to the depositary or its nominee as the holder of that global security.  Neither
we nor the trustee will have any  responsibility  or liability for any aspect of
the  records  relating to or payments  made on account of  beneficial  ownership
interests of a global security, or for maintaining, supervising or reviewing any
records  relating  to  beneficial  ownership  interests  and  each of us and the
trustee may act or refrain  from acting  without  liability  on any  information
provided by the depositary.

     We expect that the  depositary,  after  receiving any payment of principal,
any premium or interest in respect of a global security, will immediately credit
the accounts of the participants with payment in amounts  proportionate to their
respective  holdings  in  principal  amount of  beneficial  interest in a global
security as shown on the records of the depositary. We also expect that payments
by participants  to owners of beneficial  interests in a global security will be
governed by standing customer  instructions and customary  practices,  as is now
the case with


                                       19



securities  held for the accounts of customers in bearer form or  registered  in
"street name," and will be the responsibility of such participants.

     Debt securities  represented by a global security will be exchangeable  for
debt  securities  in definitive  form of like tenor in authorized  denominations
only if the depositary notifies us that it is unwilling or unable to continue as
the depositary and a successor  depositary is not appointed by us within 90 days
or we, in our discretion, determine not to require all of the debt securities of
a series to be  represented  by a global  security and notify the trustee of our
decision.

DEFEASANCE

     When we use the term  "defeasance,"  we mean  discharge from some or all of
our obligations under the indenture.  If we deposit with the trustee  sufficient
cash or government  securities to pay the principal,  any premium,  interest and
any other  sums due to the  stated  maturity  date or a  redemption  date of the
securities of a particular series, then at our option:

     o    we will be discharged from our obligations with respect to the
          securities of such series; or

     o    we will no longer be under any obligation to comply with certain
          restrictive covenants under the indenture, and certain events of
          default will no longer apply to us.

     If this happens,  the holders of the securities of the affected series will
not be entitled to the  benefits of the  indenture  except for  registration  of
transfer and exchange of debt  securities  and  replacement  of lost,  stolen or
mutilated  securities.  Such  holders may look only to such  deposited  funds or
obligations for payment.

     To  exercise  our  defeasance  option,  we must  deliver to the  trustee an
opinion of counsel to the effect that the deposit and related  defeasance  would
not cause the holders of the  securities to recognize  income,  gain or loss for
federal  income tax  purposes.  We must also  deliver  any ruling to such effect
received from or published by the United States  Internal  Revenue Service if we
are discharged from our obligations with respect to the securities.

CONCERNING THE TRUSTEE

     The trustee,  The Bank of New York, and certain of its  affiliates  have in
the past and currently do provide banking,  investment and other services to us,
including  acting as a lender under our revolving  credit  agreement,  acting as
trustee under the indenture, dated as of November 26, 2003, acting as a transfer
agent for our common shares and providing cash management  services,  and may do
so in the future as a part of its regular business.

                          DESCRIPTION OF CAPITAL STOCK

     This section  contains a description  of our capital stock and  stockholder
rights  plan.  The  following  summary  of the  terms of our  capital  stock and
stockholder  rights  plan  is not  meant  to be  complete  and is  qualified  by
reference to our  certificate  of  incorporation,  as amended,  our by-


                                       20



laws, as amended,  and our stockholder  rights plan,  which are  incorporated by
reference as exhibits into the  registration  statement of which this prospectus
is a part.

     As of March 31, 2004,  our  authorized  capital stock  consisted of: (i)
2,400,000,000  common shares, par value $0.50 per share, of which  1,471,856,132
were issued and outstanding,  557,830,245 were issued and held in treasury,  and
72,000,000  were reserved for issuance  under stock  incentive  plans;  and (ii)
50,000,000 preferred shares, par value $1.00 per share,  consisting of 1,500,000
shares  designated as Series A Junior  Participating  Preferred Stock ("Series A
preferred  stock") and 48,500,000  shares whose  designations  have not yet been
determined.  As  of  March  31,  2004,  no  preferred  shares  were  issued  and
outstanding.

COMMON SHARES

     Holders of our common  shares,  subject to any  preferential  rights of the
holders of any preferred shares, are entitled to participate equally and ratably
in dividends when and as declared by our board of directors. In the event of the
liquidation or dissolution of Schering-Plough,  holders of our common shares are
entitled to share ratably in the remaining assets of  Schering-Plough  available
for distribution,  subject to prior or equal distribution  rights of any holders
of preferred  shares.  Record  holders of common shares are entitled to one vote
per share for the election of directors and upon all matters on which holders of
common  shares are  entitled to vote.  Holders of our common  shares do not have
cumulative  voting  rights.   There  are  no  preemptive  or  conversion  rights
applicable to our common shares. All outstanding shares of our common shares are
fully paid and non-assessable.

     Each common  share has  attached  thereto a right to purchase  1/200th of a
share of our Series A preferred  stock, par value $1.00 per share, at a price of
$100 per 1/200th of a share of Series A preferred stock,  subject to adjustment.
For a description and terms of the Rights, see " -- Antitakeover  Protections --
Rights Plan."

PREFERRED SHARES

     Our certificate of  incorporation,  as amended,  provides that our board of
directors is  authorized to issue  preferred  shares from time to time in one or
more series without stockholder approval.  Subject to limitations  prescribed by
law and our certificate of incorporation, our board of directors may fix for any
series of  preferred  shares the number of shares of such  series and the voting
powers,  designations,  preferences,  rights,  qualifications,  limitations  and
restrictions   of  such  series.   There  are  currently  no  preferred   shares
outstanding.

     Our certificate of  incorporation  provides that whenever we are in default
as to accrued  dividends  on  preferred  shares in an amount  equivalent  to six
quarterly  dividends,  the holders of preferred  shares,  voting separately as a
class,  will be  entitled to elect two  directors  at the next annual or special
meeting of our  shareholders.  The right of holders of preferred shares to elect
two directors will continue until  dividends in default on the preferred  shares
have been paid in full or declared and a sum sufficient for the payment  thereof
has been set aside. During any time that the holders of preferred shares, voting
as a class, are entitled to elect two directors, as described in this paragraph,
the holders of any series of preferred  shares normally  entitled to


                                       21



participate  with the holders of the common  shares in the election of directors
shall not be entitled to  participate  with the holders of the common  shares in
the election of such directors.

     For any  series of  preferred  shares  that we may issue  pursuant  to this
registration statement, our board of directors will determine and the prospectus
supplement relating to such series will describe:

     o    The designation and number of shares of such series;

     o    The rate and time at which, and the preferences and conditions under
          which, any dividends will be paid on shares of such series, as well as
          whether such dividends are cumulative or non-cumulative and
          participating or non-participating;

     o    Any provisions relating to convertibility or exchangeability of the
          shares of such series;

     o    The rights and preferences, if any, of holders of shares of such
          series upon our liquidation, dissolution or winding up of our affairs;

     o    The voting powers, if any, of the holders of shares of such series;

     o    Any provisions relating to the redemption of the shares of such
          series;

     o    Whether and upon what terms a sinking fund will be used to purchase or
          redeem the shares;

     o    Any limitations on our ability to pay dividends or make distributions
          on, or acquire or redeem, other securities while shares of such series
          are outstanding;

     o    Any conditions or restrictions on our ability to issue additional
          shares of such series or other securities;

     o    Any other relative power, preferences and participating, optional or
          special rights of shares of such series, and the qualifications,
          limitations or restrictions thereof.

     When we issue  preferred  shares under this  prospectus  and any applicable
prospectus supplement, the shares will be fully paid and non-assessable and will
not have, or be subject to, any preemptive or similar rights.

SERIES A PREFERRED STOCK

     There are  currently no shares of our Series A preferred  stock,  par value
$1.00  per share  outstanding.  The  issuance  of  Series A  preferred  stock is
contingent on the satisfaction of certain  conditions  precedent as described in
"--  Antitakeover  Protections  -- Rights Plan," below.  The  description of the
Series A preferred  stock  reflects  corresponding  adjustments  pursuant to the
anti-dilution provisions of the Series A preferred stock.


                                       22



     Holders of each share of Series A  preferred  stock will be  entitled  to a
minimum preferential  quarterly dividend payment of $1.00 per share, but will be
entitled to an aggregate  dividend of 200 times the dividend  declared per share
of our common shares since the previous quarterly dividend payment. In the event
of  liquidation,  the holders of Series A preferred  stock will be entitled to a
minimum  preferential  liquidation  payment of $100 per share plus  accrued  and
unpaid dividends,  but will be entitled to an aggregate payment of 200 times the
payment  made per share of our common  shares.  Each share of Series A preferred
stock will have 200 votes,  voting together with the common shares.  Finally, in
the event of any merger,  consolidation or other transaction in which our common
shares are exchanged, each share of Series A preferred stock will be entitled to
receive 200 times the amount  received per share of common shares.  These rights
are protected by customary  antidilution  provisions.  Series A preferred  stock
purchasable  upon  exercise  of the  Rights  (as  defined  in  "--  Antitakeover
Protections -- Rights Plan" below) will not be redeemable.

     Because  of  the  nature  of  the  Series  A  preferred  stock's  dividend,
liquidation and voting rights,  the value of the 1/200th  interest in a share of
Series  A  preferred  stock  purchasable  upon  exercise  of each  Right  should
approximate the value of one of our common shares.

     If we are in default as to dividend  payments or  distributions on Series A
preferred  stock,  we may  not  declare  or pay  dividends  or  make  any  other
distributions  on any  shares  of  stock  (i)  ranking  junior  to the  Series A
preferred  stock  (including  common  shares) or (ii)  ranking on a parity  with
Series A preferred  stock,  except for  dividends  paid  ratably on the Series A
preferred  stock and the  other  shares of equal  rank  thereto;  and we may not
redeem,  purchase or otherwise acquire for consideration any shares of stock (i)
ranking junior to the Series A preferred  stock,  except that we may at any time
redeem,  purchase  or  otherwise  acquire  shares  of any such  junior  stock in
exchange  for shares of other  junior  stock,  or (ii) on a parity with Series A
preferred stock,  except in accordance with a purchase offer made to all holders
of such shares upon such terms as our board of directors shall determine in good
faith will result in fair and equitable treatment among the respective series or
classes being redeemed or repurchased.

     Our  certificate  of  incorporation  may not be amended in any manner which
would  materially  alter or change the powers,  preferences or special rights of
Series A preferred stock so as to affect them adversely  without the affirmative
vote of the  holders of at least  2/3rds of the  outstanding  Series A preferred
stock, voting together as a single class.

ANTITAKEOVER PROTECTIONS

     The following  discussion  summarizes  certain provisions of the New Jersey
Business  Corporation  Act, as amended (the "NJBCA") and of our  certificate  of
incorporation and by-laws, which may have the effect of prohibiting, raising the
costs of, or otherwise  impeding,  a change of control of us, whether by merger,
consolidation  or sale of assets or stock (by tender offer or otherwise),  or by
other methods.

CLASSIFIED BOARD OF DIRECTORS

     Pursuant to our  certificate  of  incorporation  and by-laws,  our board of
directors  is divided  into three  classes,  and the  directors  are  elected by
classes to staggered  three-year  terms, so that


                                       23



one of the three classes of the directors will be elected at each annual meeting
of our shareholders.

     Our  certificate  of  incorporation  and by-laws  further  require that any
proposal  to either  remove a  director  during his term of office  (other  than
pursuant to the rights, if any, of the holders of any series of preferred shares
then  outstanding)  or amend our  certificate of  incorporation  or by-laws with
respect to, among other things, the classification, number, removal, and filling
of vacancies, of directors be approved by the affirmative vote of the holders of
not less than 80% of the  voting  power of all of the  shares  entitled  to vote
generally  in the  election of  directors,  voting  together as a single  class.
Subject to the rights of the  holders  of any  series of  outstanding  preferred
shares,  any  vacancies in our board of directors may be filled by the remaining
directors.

     The purpose of these provisions is to prevent  directors from being removed
from office prior to the expiration of their respective  terms,  thus protecting
the safeguards inherent in the classified board structure unless dissatisfaction
with the performance of one or more directors is widely shared by holders of our
common  shares.  However,  these  provisions  could  also  have  the  effect  of
increasing from one year to two or three years (depending upon the number of our
common  shares  held) the  amount of time  required  for an  acquiror  to obtain
control of us by electing a majority of our board of directors and may also make
the removal of incumbent management more difficult and discourage or render more
difficult  certain mergers,  tender offers,  proxy contests,  or other potential
takeover  proposals.  To the  extent  that these  provisions  have the effect of
giving  management  more  bargaining  power  in  negotiations  with a  potential
acquiror,  they could result in management's using the bargaining power not only
to try to negotiate a favorable price for an acquisition,  but also to negotiate
more favorable terms for management.

LIMITS ON SHAREHOLDER ACTION BY WRITTEN CONSENT; SPECIAL MEETINGS

     Our certificate of incorporation  and by-laws provide that,  subject to the
rights of the holders of any series of preferred  shares then  outstanding,  any
action required or permitted to be taken by our shareholders must be effected at
a duly called annual or special meeting of shareholders  and may not be effected
by any consent in writing by such  shareholders  unless all of the  shareholders
entitled  to  vote  on  the  matter  consent  in  writing.  Our  certificate  of
incorporation and by-laws also provide that, the affirmative vote of the holders
of not less than 80% of the voting  power of all of the shares  entitled to vote
generally in the election of directors,  voting together as a single class, will
be required to amend our certificate of incorporation or by-laws with respect to
shareholder action by written consent.

     Except as otherwise  provided by the NJBCA,  under our  by-laws,  a special
meeting of our  shareholders  may only be called by the Chairman of our board of
directors,  our company President or our board of directors and shall be held at
such time and such place and for such  purpose(s) as stated in the notice of the
meeting.  No  business  other than that  stated in the notice of meeting  may be
transacted at any special meeting.


                                       24



     The above  provisions  may have the effect of delaying  consideration  of a
stockholder  proposal until the next annual meeting unless a special  meeting is
called by the Chairman of our board of directors,  our company  President or our
board of directors.

CORPORATION'S BEST INTEREST

     Under the NJBCA, the director of a New Jersey corporation may consider,  in
discharging his or her duties to the  corporation and in determining  what he or
she reasonably  believes to be in the best interest of the  corporation,  any of
the  following (in addition to the effects of any action on  shareholders):  (i)
the effects of the action on the corporation's employees,  suppliers,  creditors
and  customers,  (ii) the  effects of the action on the  community  in which the
corporation operates, and (iii) the long-term as well as the short-term interest
of the corporation and its  shareholders,  including the possibility  that these
interests may be best served by the continued  independence of the  corporation.
If,  on the  basis of any of the  foregoing  factors,  the  board  of  directors
determines  that any proposal or offer to acquire the  corporation is not in the
best interest of the corporation, it may reject such proposal or offer, in which
event the board of directors  will have no duty to remove any  obstacles  to, or
refrain from impeding, such proposal or offer.

REQUIRED VOTE FOR AUTHORIZATION OF CERTAIN ACTIONS; ANTI-GREENMAIL PROVISIONS

     Under the NJBCA,  the  consummation of a merger or  consolidation  of a New
Jersey corporation organized subsequent to January 1, 1969, such as us, requires
the approval of such  corporation's  board of directors and the affirmative vote
of a  majority  of the  votes  cast by  each of the  holders  of  shares  of the
corporation  entitled to vote  thereon and any class or series  entitled to vote
thereon as a class, unless such corporation is the surviving  corporation,  and:
(i) such  corporation's  certificate of incorporation  is not amended,  (ii) the
stockholders  of  the  surviving   corporation  whose  shares  were  outstanding
immediately before the effective date of the merger will hold the same number of
shares,  with  identical  designations,  preferences,  limitations,  and rights,
immediately after the merger or consolidation, as the case may be, and (iii) the
number of voting shares and  participating  shares  outstanding after the merger
will not  exceed by more than 40% the  total  number of voting or  participating
shares of the surviving corporation immediately before the merger. Similarly, in
the case of a New Jersey corporation organized subsequent to 1969, such as us, a
sale of all or  substantially  all of a  corporation's  assets other than in the
ordinary  course of  business,  or a  voluntary  dissolution  of a  corporation,
requires  the  approval  of  such  corporation's  board  of  directors  and  the
affirmative  vote of a  majority  of the votes  cast by each of the  holders  of
shares  of the  corporation  entitled  to vote  thereon  and any class or series
entitled to vote thereon as a class.

     Our certificate of  incorporation  contains an  "anti-greenmail"  provision
pursuant to which we or our subsidiaries may not purchase shares of voting stock
from a 5% or greater  shareholder  at a per share  price in excess of the market
price unless (a) approved by the  affirmative  vote of the holders of the amount
of voting power of the voting stock equal to the sum of the voting power of such
5% or greater  shareholder  and a majority of the voting power of the  remaining
outstanding  shares of voting stock,  voting  together as a single class, or (b)
the purchase is made  pursuant to an offer made  available to all holders of the
same class of stock or an open market purchase.


                                       25



RESTRICTIONS ON BUSINESS COMBINATIONS WITH CERTAIN STOCKHOLDERS

     The NJBCA  provides  that no  corporation  organized  under the laws of New
Jersey with its principal executive offices or significant operations located in
New Jersey (a  "resident  domestic  corporation")  may  engage in any  "business
combination"  (as  defined  in  the  NJBCA)  with  any  interested   stockholder
(generally,  a 10% or greater  stockholder) of such  corporation for a period of
five years following such interested  stockholder's  stock  acquisition,  unless
such  business  combination  is  approved  by the  board  of  directors  of such
corporation prior to the stock  acquisition.  A resident  domestic  corporation,
such as us, cannot opt out of the foregoing provisions of the NJBCA.

     In addition,  no resident domestic  corporation may engage, at any time, in
any business  combination  with any interested  stockholder of such  corporation
other than:  (i) a business  combination  approved by the board of  directors of
such corporation  prior to the stock  acquisition,  (ii) a business  combination
approved  by the  affirmative  vote of the holders of  two-thirds  of the voting
stock not beneficially owned by such interested  stockholder at a meeting called
for such  purpose,  or (iii) a  business  combination  in which  the  interested
stockholder pays a formula price designed to ensure that all other  stockholders
receive  at  least  the  highest  price  per  share  paid  by  such   interested
stockholder.

     In connection with business  combinations with any ten percent stockholder,
our certificate of incorporation  contains provisions  requiring the approval of
at  least  80% of the  voting  power of all of the then  outstanding  shares  of
capital stock of the  corporation  entitled to vote in the election of directors
voting  together as a single  class;  provided,  however,  that such higher vote
requirements  do not apply if the  business  combination  (i) is  approved  by a
majority  of  directors  in  office  prior  to the  stock  acquisition  and  not
affiliated with the interested  stockholders or by their successors  recommended
by a majority of such  unaffiliated,  pre-stock-acquisition  date directors,  or
(ii)  meets  certain  fair  price  formulas  set  forth  in our  certificate  of
incorporation.  Any amendments or repeal of the business combination  provisions
require the affirmative  vote of the holders of 80% or more of the voting power
of all of the shares entitled to vote, voting together as a single class.

RIGHTS PLAN

     On June 24,  1997,  our  board of  directors  declared  a  dividend  of one
preferred  share  purchase  right  (a  "Right")  for each of our  common  shares
outstanding at the close of business on July 10, 1997 (the "Record Date") to the
stockholders of record on that date.  Each Right entitles the registered  holder
to  purchase  from us 1/200th of a share of our Series A preferred  stock,  at a
price of $100 per 1/200th of a share of Series A preferred  stock (the "Purchase
Price"), subject to adjustment.  The description and terms of the Rights are set
forth in a Rights Agreement (the "Rights Agreement"), dated as of June 24, 1997,
between us and The Bank of New York, as Rights Agent (the "Rights Agent").  This
summary  description of the Rights and the Rights  Agreement does not purport to
be  complete  and is  qualified  in its  entirety  by  reference  to the  Rights
Agreement,  and the certificates of adjustments  with respect  thereto,  each of
which is incorporated by reference into this prospectus.


                                       26



     Until the earlier to occur of: (i) 10 days following a public  announcement
that a person  or group of  affiliated  or  associated  persons  (an  "Acquiring
Person") have acquired  beneficial  ownership of 20% or more of the  outstanding
common shares, or (ii) 10 business days (or such later date as may be determined
by action of our board of directors prior to such time as any person or group of
affiliated  persons becomes an Acquiring  Person) following the commencement of,
or  announcement  of an intention to make, a tender offer or exchange  offer the
consummation  of which would result in the  beneficial  ownership by a person or
group of 20% or more of the outstanding common shares (the earlier of such dates
being  called the  "Distribution  Date"),  the Rights  will be  evidenced,  with
respect to any of our common  share  certificates  outstanding  as of the Record
Date,  by such  common  share  certificate  with a copy of the summary of Rights
attached thereto.

     The Rights Agreement provides that, until the Distribution Date (or earlier
redemption or expiration of the Rights), the Rights will be transferred with and
only with common shares.  Until the Distribution Date (or earlier  redemption or
expiration of the Rights), new common share certificates issued after the Record
Date upon  transfer or new issuance of our common shares will contain a notation
incorporating the Rights Agreement by reference. Until the Distribution Date (or
earlier  redemption or expiration of the Rights),  the surrender for transfer of
any certificates  for our common shares  outstanding as of the Record Date, even
without such notation or a copy of the summary of Rights being attached thereto,
will also  constitute  the  transfer  of the Rights  associated  with the common
shares  represented by such  certificate.  As soon as practicable  following the
Distribution  Date,   separate   certificates   evidencing  the  Rights  ("Right
Certificates")  will be mailed to holders  of record of our common  shares as of
the  close  of  business  on the  Distribution  Date  and  such  separate  Right
Certificates alone will evidence the Rights.

     The Rights are not exercisable until the Distribution Date. The Rights will
expire  on July 10,  2007  (the  "Final  Expiration  Date"),  unless  the  Final
Expiration  Date is  extended  or unless  the  Rights are  earlier  redeemed  or
exchanged by us, in each case, as described below.

     The Purchase Price payable,  and the number of shares of Series A preferred
stock, or other securities or property, issuable upon exercise of the Rights are
subject to adjustment from time to time to prevent dilution: (i) in the event of
a stock  dividend on, or a  subdivision,  combination  or  reclassification  of,
Series A preferred  stock,  (ii) upon the grant to holders of Series A preferred
stock of certain  rights or  warrants  to  subscribe  for or  purchase  Series A
preferred  stock at a price, or securities  convertible  into Series A preferred
stock with a conversion price, less than the then-current market price of Series
A  preferred  stock,  or (iii)  upon the  distribution  to  holders  of Series A
preferred  stock of  evidences  of  indebtedness  or assets  (excluding  regular
periodic cash dividends  paid out of earnings or retained  earnings or dividends
payable  in Series A  preferred  stock) or of  subscription  rights or  warrants
(other than those referred to above).

     The number of  outstanding  Rights and the number of 1/200ths of a share of
Series A preferred  stock  issuable upon exercise of each Right are also subject
to adjustment in the event of a stock split of or a stock dividend on our common
shares  payable  in  our  common  shares  or  subdivisions,   consolidations  or
combinations  of our common  shares  occurring,  in any such case,  prior to the
Distribution Date.


                                       27



     In the event that we are acquired in a merger or other business combination
transaction or 50% or more of our consolidated  assets or earning power are sold
after a person or group has become an Acquiring Person, proper provision will be
made so that each holder of a Right will  thereafter  have the right to receive,
upon the exercise thereof at the then current exercise price of the Right,  that
number of shares of common stock of the  acquiring  company which at the time of
such transaction will have a market value of two times the exercise price of the
Right. In the event that any person or group of affiliated or associated persons
becomes an Acquiring Person,  proper provision shall be made so that each holder
of a Right, other than Rights  beneficially owned by the Acquiring Person (which
will  thereafter  be  void),  will  thereafter  have the right to  receive  upon
exercise  that number of common  shares  having a market  value of two times the
exercise price of the Right.

     At any time after any person or group becomes an Acquiring Person and prior
to the  acquisition  by such  person or group of 50% or more of the  outstanding
common shares, our board of directors may exchange the Rights (other than Rights
owned by such person or group which will have become void), in whole or in part,
at an  exchange  ratio of one  common  share,  or 1/200th of a share of Series A
preferred  stock  (or of a share of a class or series  of our  preferred  shares
having  equivalent  rights,  preferences and privileges),  per Right (subject to
adjustment).

     With  certain  exceptions,  no  adjustment  in the  Purchase  Price will be
required until  cumulative  adjustments  require an adjustment of at least 1% in
such Purchase  Price.  No fractional  shares of Series A preferred stock will be
issued (other than fractions which are integral  multiples of 1/100th of a share
of Series A  preferred  stock,  which may,  at our  election,  be  evidenced  by
depositary  receipts) and in lieu thereof,  a payment in cash will be made based
on the market price of Series A preferred stock on the last trading day prior to
the date of exercise.

     At any time prior to the  acquisition by a person or group of affiliated or
associated  persons of  beneficial  ownership of 20% or more of the  outstanding
common shares, our board of directors may redeem the Rights in whole, but not in
part, at a price of $0.005 per Right (the "Redemption Price"). The redemption of
the Rights may be made effective at such time on such basis with such conditions
as our board of directors in its sole discretion may establish. Immediately upon
any  redemption of the Rights,  the right to exercise the Rights will  terminate
and the only right of the holders of Rights  will be to receive  the  Redemption
Price.

     The terms of the Rights may be  amended by our board of  directors  without
the  consent of the  holders of the  Rights,  including  an  amendment  to lower
certain thresholds  described above to not less than the greater of: (i) the sum
of .001% and the largest  percentage of the outstanding common shares then known
to us to be  beneficially  owned  by  any  person  or  group  of  affiliated  or
associated  persons,  and (ii) 10%,  except that from and after such time as any
person or group of affiliated or associated  persons becomes an Acquiring Person
no such  amendment  may  adversely  affect the  interests  of the holders of the
Rights.

     Until a Right is  exercised,  the  holder  thereof,  as such,  will have no
rights as one of our stockholders,  including,  without limitation, the right to
vote or to receive dividends.


                                       28



     The Rights  have  certain  anti-takeover  effects.  The  Rights  will cause
substantial  dilution to a person or group that  attempts to acquire us on terms
not approved by our board of directors,  except pursuant to an offer conditioned
on a  substantial  number  of Rights  being  acquired.  The  Rights  should  not
interfere with any merger or other business combination approved by our board of
directors  since the Rights may be redeemed by us at the Redemption  Price prior
to the time that a person or group has acquired  beneficial  ownership of 20% or
more of our common shares.

                       DESCRIPTION OF DEPOSITARY SHARES

     We may elect to offer  fractional  shares of preferred  shares  rather than
full shares of  preferred  shares.  In that event,  we will issue  receipts  for
depositary shares, and each of these depositary shares will represent a fraction
(to be set  forth  in the  applicable  prospectus  supplement)  of a share  of a
particular series of preferred shares.

     The shares of any series of  preferred  shares  underlying  the  depositary
shares  will be  deposited  under a deposit  agreement  between us and a bank or
trust company  selected by us. The depositary will have its principal  office in
the United  States and a combined  capital and surplus of at least  $50,000,000.
Subject to the terms of the deposit agreement,  each owner of a depositary share
will be  entitled,  in  proportion  to the  applicable  fraction  of a share  of
preferred  shares  underlying  the  depositary  share,  to all  the  rights  and
preferences of the preferred  shares  underlying  that depositary  share.  Those
rights may include  dividend,  voting,  redemption,  conversion and  liquidation
rights.

     The depositary shares will be evidenced by depositary receipts issued under
a deposit  agreement.  Depositary  receipts will be distributed to those persons
purchasing the fractional  shares of preferred shares  underlying the depositary
shares, in accordance with the terms of the offering.  The following description
of the material terms of the deposit  agreement,  the depositary  shares and the
depositary  receipts is only a summary and you should  refer to the forms of the
deposit  agreement  and  depositary  receipts that will be filed with the SEC in
connection with the offering of the specific depositary shares for more complete
information.

     Pending the preparation of definitive  engraved  depositary  receipts,  the
depositary  may, upon our written order,  issue  temporary  depositary  receipts
substantially  identical  to  the  definitive  depositary  receipts  but  not in
definitive  form. These temporary  depositary  receipts entitle their holders to
all the rights of definitive depositary receipts.  Temporary depositary receipts
will then be exchangeable for definitive depositary receipts at our expense.

DIVIDENDS AND OTHER DISTRIBUTIONS

     The   depositary   will   distribute  all  cash  dividends  or  other  cash
distributions  received  with  respect  to the  underlying  stock to the  record
holders of depositary  shares in  proportion to the number of depositary  shares
owned by those holders.

     If  there  is a  distribution  other  than in  cash,  the  depositary  will
distribute  property  received by it to the record holders of depositary  shares
that are entitled to receive the distribution,  unless the depositary determines
that it is not feasible to make the distribution. If this occurs, the


                                       29



depositary  may, with our  approval,  sell the property and  distribute  the net
proceeds from the sale to the applicable holders.

WITHDRAWAL OF UNDERLYING PREFERRED SHARES

     Unless we say otherwise in a prospectus  supplement,  holders may surrender
depositary  receipts at the principal office of the depositary and, upon payment
of any unpaid amount due to the depositary, be entitled to receive the number of
whole shares of  underlying  preferred  shares and all money and other  property
represented  by the  related  depositary  shares.  We will not issue any partial
shares  of  preferred  shares.  If  the  holder  delivers   depositary  receipts
evidencing a number of depositary shares that represent more than a whole number
of shares of  preferred  shares,  the  depositary  will  issue a new  depositary
receipt evidencing the excess number of depositary shares to that holder.

REDEMPTION OF DEPOSITARY SHARES

     If a series of preferred shares represented by depositary shares is subject
to redemption, the depositary shares will be redeemed from the proceeds received
by the depositary  resulting from the  redemption,  in whole or in part, of that
series of underlying  stock held by the  depositary.  The  redemption  price per
depositary  share will be equal to the  applicable  fraction  of the  redemption
price per share  payable  with  respect  to that  series  of  underlying  stock.
Whenever we redeem shares of underlying  stock that are held by the  depositary,
the  depositary  will  redeem,  as of the same  redemption  date,  the number of
depositary  shares  representing the shares of underlying stock so redeemed.  If
fewer than all the depositary  shares are to be redeemed,  the depositary shares
to be redeemed  will be selected by lot or  proportionately  or other  equitable
method, as may be determined by the depositary.

VOTING

     Upon  receipt  of  notice  of any  meeting  at  which  the  holders  of the
underlying  stock are entitled to vote, the depositary will mail the information
contained  in the  notice  to  the  record  holders  of  the  depositary  shares
underlying the preferred shares.  Each record holder of the depositary shares on
the  record  date  (which  will be the  same  date as the  record  date  for the
underlying stock) will be entitled to instruct the depositary as to the exercise
of  the  voting  rights  pertaining  to  the  amount  of  the  underlying  stock
represented by that holder's depositary shares. The depositary will then try, as
far as practicable,  to vote the number of shares of preferred shares underlying
those depositary shares in accordance with those instructions, and we will agree
to take all reasonable  actions which may be deemed  necessary by the depositary
to enable the depositary to do so. The  depositary  will not vote the underlying
shares to the extent it does not receive specific  instructions  with respect to
the depositary shares representing the preferred shares.

CONVERSION OR EXCHANGE OF PREFERRED SHARES

     If the deposited  preferred shares are convertible into or exchangeable for
other securities, the following will apply. The depositary shares, as such, will
not be convertible into or exchangeable for such other securities.  Rather,  any
holder of the depositary shares may


                                       30



surrender the related depositary receipts,  together with any amounts payable by
the holder in connection with the conversion or the exchange,  to the depositary
with  written  instructions  to cause  conversion  or exchange of the  preferred
shares  represented by the depositary  shares into or for such other securities.
If only some of the  depositary  shares are to be converted or exchanged,  a new
depositary  receipt or receipts will be issued for any depositary  shares not to
be converted or exchanged.

AMENDMENT AND TERMINATION OF THE DEPOSIT AGREEMENT

     The form of depositary  receipt  evidencing the  depositary  shares and any
provision  of the  deposit  agreement  may at any time be amended  by  agreement
between us and the  depositary.  However,  any amendment  which  materially  and
adversely  alters the rights of the  holders of  depositary  shares  will not be
effective  unless the  amendment  has been approved by the holders of at least a
majority of the depositary shares then outstanding. The deposit agreement may be
terminated  by us upon not less than 60 days' notice  whereupon  the  depositary
shall  deliver or make  available  to each  holder of  depositary  shares,  upon
surrender of the depositary receipts held by such holder, the number of whole or
fractional shares of preferred shares represented by such receipts.  The deposit
agreement will automatically  terminate if (a) all outstanding depositary shares
have been redeemed or converted into or exchanged for any other  securities into
or for which the underlying  preferred shares are convertible or exchangeable or
(b) there has been a final  distribution  of the underlying  stock in connection
with our  liquidation,  dissolution or winding up and the  underlying  stock has
been distributed to the holders of depositary receipts.

CHARGES OF DEPOSITARY

     We will pay all transfer and other taxes and  governmental  charges arising
solely  from the  existence  of the  depositary  arrangements.  We will also pay
charges of the depositary in connection  with its duties in accordance  with the
deposit  agreement.  Holders of depositary  receipts will pay transfer and other
taxes and  governmental  and other  charges,  including a fee for any  permitted
withdrawal of shares of underlying stock upon surrender of depositary  receipts,
as are expressly provided in the deposit agreement to be for their accounts.

REPORTS

     The depositary  will forward to holders of depositary  receipts all reports
and  communications  from us that we deliver to the  depositary  and that we are
required to furnish to the holders of the underlying stock.

LIMITATION ON LIABILITY

     Neither we nor the  depositary  will be liable if either of us is prevented
or  delayed by law or any  circumstance  beyond our  control in  performing  our
respective obligations under the deposit agreement. Our obligations and those of
the  depositary  will be limited to  performance in good faith of our respective
duties  under the  deposit  agreement.  Neither  we nor the  depositary  will be
obligated  to  prosecute  or  defend  any legal  proceeding  in  respect  of any
depositary  shares  or  underlying  stock  unless   satisfactory   indemnity  is
furnished.  We and the  depositary  may rely upon  written  advice of counsel or
accountants, or upon information provided by persons


                                       31



presenting underlying stock for deposit, holders of depositary receipts or other
persons believed to be competent and on documents believed to be genuine.

     In the  event the  depositary  receives  conflicting  claims,  requests  or
instructions from any holders of depositary  shares, on the one hand, and us, on
the other, the depositary will act on our claims, requests or instructions.

RESIGNATION AND REMOVAL OF DEPOSITARY

     The  depositary  may resign at any time by  delivering  notice to us of its
election to resign. We may remove the depositary at any time. Any resignation or
removal will take effect upon the appointment of a successor  depositary and its
acceptance of the appointment. The successor depositary must be appointed within
60 days after  delivery  of the notice of  resignation  or removal and must be a
bank or trust  company  having its  principal  office in the  United  States and
having a combined capital and surplus of at least $50,000,000.

                           DESCRIPTION OF WARRANTS

     The following is a general  description of the terms of the warrants we may
issue from time to time. This description is subject to the detailed  provisions
of a warrant  agreement  to be entered  into  between us and a warrant  agent we
select at the time of issue and the  description  in the  prospectus  supplement
relating to the applicable series of warrants.

GENERAL

     We may issue  warrants  to  purchase  debt  securities,  preferred  shares,
depositary shares,  common shares or any combination thereof.  Such warrants may
be issued independently or together with any such securities and may be attached
or separate from such  securities.  We may issue each series of warrants under a
separate  warrant  agreement to be entered into between a warrant  agent and us.
The  warrant  agent  will act  solely  as our  agent  and will  not  assume  any
obligation or relationship of agency for or with holders or beneficial owners of
warrants.

     A prospectus supplement will describe the particular terms of any series of
warrants we may issue, including the following:

     o    the title of such warrants;

     o    the aggregate number of such warrants;

     o    the price or prices at which such warrants will be issued;

     o    the currency or currencies, including composite currencies, in which
          the price of such warrants may be payable;

          of such warrants and the number of such securities issuable upon
          exercise of such warrants;


                                       32



     o    the price at which and the currency or currencies, including composite
          currencies, in which the securities purchasable upon exercise of such
          warrants may be purchased;

     o    the date on which the right to exercise such warrants shall commence
          and the date on which such right will expire;

     o    whether such warrants will be issued in registered form or bearer
          form;

     o    if applicable, the minimum or maximum amount of such warrants which
          may be exercised at any one time;

     o    if applicable, the designation and terms of the securities with which
          such warrants are issued and the number of such warrants issued with
          each such security;

     o    if applicable, the date on and after which such warrants and the
          related securities will be separately transferable;

     o    information with respect to book-entry procedures, if any;

     o    if applicable, a discussion of certain U.S. federal income tax
          considerations; and

     o    any other terms of such warrants, including terms, procedures and
          limitations relating to the exchange and exercise of such warrants.

AMENDMENTS AND SUPPLEMENTS TO WARRANT AGREEMENT

     We and the warrant agent may amend or supplement the warrant  agreement for
a series of warrants  without the consent of the holders of the warrants  issued
thereunder to effect  changes that are not  inconsistent  with the provisions of
the warrants and that do not  materially  and adversely  affect the interests of
the holders of the warrants.

                   DESCRIPTION OF STOCK PURCHASE CONTRACTS
                           AND STOCK PURCHASE UNITS

     The following is a general  description  of the terms of the stock purchase
contracts and stock purchase units we may issue from time to time.

     The applicable  prospectus  supplement will describe the terms of any stock
purchase  contracts or stock purchase  units and, if  applicable,  prepaid stock
purchase  contracts.  The  description  in the  prospectus  supplement  will  be
qualified in its entirety by reference to (1) the stock purchase contracts,  (2)
the collateral arrangements and depositary arrangements, if applicable, relating
to such stock purchase  contracts or stock purchase units and (3) if applicable,
the prepaid stock  purchase  contracts  and the document  pursuant to which such
prepaid stock purchase contracts will be issued.


                                       33



STOCK PURCHASE CONTRACTS

     We may issue  stock  purchase  contracts,  including  contracts  obligating
holders to purchase from us, and  obligating  us to sell to holders,  a fixed or
varying  number of common  shares,  preferred  shares or depositary  shares at a
future date or dates. The  consideration  per share of common shares,  preferred
shares or  depositary  shares  may be fixed at the time that the stock  purchase
contracts are issued or may be determined by reference to a specific formula set
forth in the stock purchase  contracts.  Any stock purchase contract may include
anti-dilution  provisions  to adjust the number of shares  issuable  pursuant to
such stock purchase contract upon the occurrence of certain events.

STOCK PURCHASE UNITS

     The stock purchase contracts may be issued separately or as a part of units
("stock  purchase  units"),  consisting  of a stock  purchase  contract and debt
securities, preferred securities or debt or equity obligations of third parties,
including U.S. Treasury  securities,  in each case securing holders' obligations
to purchase common shares, preferred shares or depositary shares under the stock
purchase contracts. The stock purchase contracts may require us to make periodic
payments  to  holders  of the stock  purchase  units,  or vice  versa,  and such
payments  may be  unsecured  or  prefunded  and may be paid on a current or on a
deferred basis. The stock purchase contracts may require holders to secure their
obligations thereunder in a specified manner and in certain circumstances we may
deliver newly issued prepaid stock  purchase  contracts upon release to a holder
of any collateral  securing such holder's  obligations  under the original stock
purchase contract. Any one or more of the above securities, common shares or the
stock purchase  contracts or other collateral may be pledged as security for the
holders' obligations to purchase or sell, as the case may be, the common shares,
preferred shares or depositary  shares under the stock purchase  contracts.  The
stock   purchase   contracts   may  also  allow  the  holders,   under   certain
circumstances, to obtain the release of the security for their obligations under
such contracts by depositing with the collateral agent as substitute collateral,
treasury  securities with a principal amount at maturity equal to the collateral
so released or the maximum  number of shares  deliverable  by such holders under
stock purchase contracts requiring the holders to sell common shares,  preferred
shares or depositary shares to us.

                             PLAN OF DISTRIBUTION

     We may sell the securities  covered by this prospectus in any of three ways
(or in any combination):

     o    through underwriters, dealers or remarketing firms;

     o    directly to one or more  purchasers,  including to a limited number of
          institutional purchasers; or

     o    through agents.

     Any such dealer or agent, in addition to any underwriter,  may be deemed to
be an  underwriter  within the meaning of the Securities Act of 1933, as amended
(the "Securities Act").


                                       34



Any discounts or commissions  received by an  underwriter,  dealer,  remarketing
firm or agent on the sale or resale of  securities  may be considered by the SEC
to be underwriting discounts and commissions under the Securities Act.

     In addition, we may enter into derivative  transactions with third parties,
or sell  securities not covered by this prospectus to third parties in privately
negotiated  transactions.  If the applicable prospectus supplement indicates, in
connection  with such a  transaction,  the third  parties may,  pursuant to this
prospectus and the applicable prospectus supplement,  sell securities covered by
this prospectus and the applicable prospectus supplement. If so, the third party
may use  securities  borrowed from us or others to settle such sales and may use
securities  received  from us to close out any related short  positions.  We may
also loan or pledge  securities  covered by this  prospectus  and the applicable
prospectus  supplement to third parties,  who may sell the loaned securities or,
in an event of  default  in the case of a pledge,  sell the  pledged  securities
pursuant to this prospectus and the applicable prospectus supplement.

     The terms of the  offering  of the  securities  with  respect to which this
prospectus is being  delivered  will be set forth in the  applicable  prospectus
supplement and will include among other things:

     o    the type of and terms of the securities offered;

     o    the price of the securities;

     o    the proceeds to us from the sale of the securities;

     o    the names of the securities exchanges, if any, on which the securities
          are listed;

     o    the name of any underwriters, dealers, remarketing firms or agents and
          the amount of securities underwritten or purchased by each of them;

     o    any  over-allotment  options  under which  underwriters  may  purchase
          additional securities from us;

     o    any underwriting discounts, agency fees or other compensation to
          underwriters or agents; and

     o    any discounts or concessions which may be allowed or reallowed or paid
          to dealers.

     If underwriters are used in the sale of securities, such securities will be
acquired by the  underwriters  for their own account and may be resold from time
to time in one or more transactions,  including  negotiated  transactions,  at a
fixed public offering price or at varying prices determined at the time of sale.
The  securities  may  be  offered  to the  public  either  through  underwriting
syndicates  represented  by  managing  underwriters  or  directly by one or more
underwriters  acting  alone.  Unless  otherwise  set  forth  in  the  applicable
prospectus  supplement,  the  obligations  of the  underwriters  to purchase the
securities described in the applicable  prospectus supplement will be subject to
certain conditions precedent, and the underwriters will


                                       35



be obligated to purchase all such  securities if any are purchased by them.  Any
public  offering price and any discounts or concessions  allowed or reallowed or
paid to dealers may be changed from time to time.

     If dealers  acting as  principals  are used in the sale of any  securities,
such  securities  will be acquired by the  dealers,  as  principals,  and may be
resold  from time to time in one or more  transactions  at varying  prices to be
determined  by the dealer at the time of resale.  The name of any dealer and the
terms of the  transaction  will be set forth in the prospectus  supplement  with
respect to the securities being offered.

     Securities  may also be offered and sold, if so indicated in the applicable
prospectus supplement,  in connection with a remarketing upon their purchase, in
accordance with a redemption or repayment pursuant to their terms, or otherwise,
by one or more  firms,  which we refer to  herein  as the  "remarketing  firms,"
acting as principals for their own accounts or as our agents, as applicable. Any
remarketing firm will be identified and the terms of its agreement, if any, with
us  and  its  compensation  will  be  described  in  the  applicable  prospectus
supplement.  Remarketing firms may be deemed to be underwriters, as that term is
defined in the  Securities  Act in  connection  with the  securities  remarketed
thereby.

     The securities  may be sold directly by us or through agents  designated by
us from  time to  time.  In the  case of  securities  sold  directly  by us,  no
underwriters  or agents would be involved.  Any agents  involved in the offer or
sale of the securities in respect of which this  prospectus is being  delivered,
and any  commissions  payable  by us to such  agents,  will be set  forth in the
applicable prospectus  supplement.  Unless otherwise indicated in the applicable
prospectus supplement, any such agent will be acting on a best efforts basis for
the period of its appointment.

GENERAL

     We may  authorize  agents,  underwriters  or dealers  to solicit  offers by
certain  specified  institutions  to  purchase  the  securities  to  which  this
prospectus  and the  applicable  prospectus  supplement  relates  from us at the
public offering price set forth in the applicable prospectus  supplement,  plus,
if  applicable,   accrued  interest,  pursuant  to  delayed  delivery  contracts
providing  for payment and  delivery  on a  specified  date in the future.  Such
contracts  will be subject only to those  conditions set forth in the applicable
prospectus  supplement,  and the applicable prospectus supplement will set forth
the commission payable for solicitation of such contracts.

     Agents, dealers,  underwriters and remarketing firms may be entitled, under
agreements  entered into with us to  indemnification by us against certain civil
liabilities,  including liabilities under the Securities Act, or to contribution
to payments they may be required to make in respect  thereof.  Agents,  dealers,
underwriters  and remarketing  firms may be customers of, engage in transactions
with, or perform  services for us or our  subsidiaries in the ordinary course of
business.

     Unless otherwise  indicated in the applicable  prospectus  supplement,  all
securities offered by this prospectus,  other than our common shares,  which are
listed on the New York Stock  Exchange,  will be new issues with no  established
trading  market.  We may elect to list any series


                                       36



of  securities  on an  exchange,  and in the case of our common  shares,  on any
additional   exchange,   but,  unless  otherwise  specified  in  the  applicable
prospectus  supplement,  we  shall  not  be  obligated  to do so.  In  addition,
underwriters  will not be  obligated  to make a  market  in any  securities.  No
assurance  can be given  regarding  the activity of trading in, or liquidity of,
any securities.

     Any  underwriter  may engage in  overallotment,  stabilizing  transactions,
short covering  transactions  and penalty bids in accordance  with  Regulation M
under the Exchange Act.  Overallotment  involves sales in excess of the offering
size,  which create a short position.  Stabilizing  transactions  permit bids to
purchase the underlying security so long as the stabilizing bids do not exceed a
specified  maximum.   Short  covering  transactions  involve  purchases  of  the
securities in the open market after the distribution is completed to cover short
positions.  Penalty bids permit the underwriters to reclaim a selling concession
from a dealer when the securities originally sold by the dealer are purchased in
a covering transaction to cover short positions.  Those activities may cause the
price of the  securities to be higher than it would  otherwise be. If commenced,
the underwriters may discontinue any of the activities at any time.

                             VALIDITY OF SECURITIES

     Unless otherwise  indicated in a supplement to this prospectus,  Lowenstein
Sandler  PC,  Roseland,  New  Jersey,  and  Joseph  J.  LaRosa,  Esq.,  our Vice
President,  Legal Affairs, will pass upon the validity of the securities for us.
As of May 6, 2004,  Mr. LaRosa  owned,  directly and  indirectly,  15,209 common
shares and options to purchase 160,780 additional common shares, 16,480 deferred
stock units which will vest over time and  16,661.01  units under our  Long-Term
Performance Plan which will vest over time and are performance based. Lowenstein
Sandler PC has from time to time provided legal services to us.

                                     EXPERTS

     The consolidated  financial  statements and the related financial statement
schedule  incorporated in this prospectus by reference from the Company's Annual
Report on Form 10-K for the year ended  December  31, 2003 have been  audited by
Deloitte & Touche LLP, independent auditors, as stated in their report, which is
incorporated herein by reference, and have been so incorporated in reliance upon
the report of such firm given upon their  authority as experts in accounting and
auditing.

     With respect to the unaudited interim financial information for the periods
ended  March  31,  2004 and 2003  which is  incorporated  herein  by  reference,
Deloitte  & Touche  LLP have  applied  limited  procedures  in  accordance  with
professional  standards for a review of such information.  However, as stated in
their report  included in the  Company's  Quarterly  Report on Form 10-Q for the
quarter ended March 31, 2004 and incorporated by reference herein,  they did not
audit and they do not express an opinion on that interim financial  information.
Accordingly,  the degree of reliance on their report on such information  should
be restricted in light of the limited nature of the review  procedures  applied.
Deloitte & Touche LLP are not subject to the liability  provisions of Section 11
of the  Securities  Act of  1933  for  their  report  on the  unaudited  interim
financial  information  because that report is not a "report" or a "part" of the
registration statement prepared or certified by an accountant within the meaning
of Sections 7 and 11 of the Securities Act.

ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     The registrant is organized under the laws of the State of New Jersey.  The
New Jersey Business  Corporation Act provides that a New Jersey  corporation has
the power to  indemnify  its  directors,  officers,  employees  and other agents
against  expenses and  liabilities in connection  with any proceeding  involving
such  person by reason of  his/her  being or having  been a  director,  officer,
employee  or other  agent if he/she  acted in good faith and in a manner  he/she
reasonably  believed  to be in or not  opposed  to  the  best  interests  of the
corporation  and,  with respect to any criminal  proceeding,  such person had no
reasonable cause to believe his/her conduct was unlawful. Expenses incurred by a
director,  officer,  employee or other agent in connection with a proceeding may
be,  under  certain  circumstances,  paid by the  corporation  before  the final
disposition of the proceeding as authorized by the board of directors. The power
to indemnify and pay expenses under the New Jersey Business Corporation Act does
not  exclude  other  rights,  including  the  right  to be  indemnified  against
liabilities  and  expenses  incurred  in  proceedings  by or in the right of the
corporation,  to which a  director,  officer,  employee  or  other  agent of the
corporation  may be entitled to under a certificate  of  incorporation,  by-law,
agreement, vote of shareholders,  or otherwise; provided that no indemnification
is  permitted  to be made to or on behalf of such  person if a judgment or other
final  adjudication  adverse to such person  establishes  that  his/her  acts or
omissions  were in breach of his/her duty of loyalty to the  corporation  or its
shareholders,  were not in good faith or  involved a  violation  of the law,  or
resulted in the receipt of such person of an improper personal benefit.

     The New Jersey Business  Corporation Act further provides that a New Jersey
corporation  has the power to purchase and  maintain  insurance on behalf of any
director,  officer, employee or other agent against any expenses incurred in any
proceeding and any  liabilities  asserted  against  him/her by reason of his/her
being or having been a director,  officer,  employee or other agent,


                                      II-1



whether or not the corporation would have the power to indemnify him/her against
such expenses and liabilities under the New Jersey Business Corporation Act.

     The registrant's  Certificate of Incorporation  provides that directors and
officers  of the  registrant  shall  not be  personally  liable  (in the case of
officers,  for the duration of any time  permitted by law) to the  registrant or
its  shareholders  for damages for breach of any duty owed to the  registrant or
its shareholders,  except for liability for any breach of duty based upon an act
or omission (i) in breach of such persons' duty of loyalty to the  registrant or
its shareholders, (ii) not in good faith or involving a knowing violation of law
or (iii) resulting in receipt by such persons of an improper personal benefit.

     The Certificate of  Incorporation of the registrant also provides that each
person who was or is made a party or is  threatened to be made a party to or who
is  involved  in  any  pending,   threatened  or  completed   civil,   criminal,
administrative or arbitrative action, suit or proceeding,  or any appeal therein
or any  inquiry  or  investigation  which  could  lead to such  action,  suit or
proceeding  (a  "proceeding"),  by reason  of  his/her  being or  having  been a
director,  officer,  employee,  or agent of the registrant or of any constituent
corporation  absorbed by the  registrant  in a  consolidation  or merger,  or by
reason of his/her being or having been a director, officer, trustee, employee or
agent of any other  corporation  (domestic  or foreign)  or of any  partnership,
joint  venture,  sole  proprietorship,  trust,  employee  benefit  plan or other
enterprise  (whether or not for  profit),  serving as such at the request of the
registrant or of any such constituent  corporation,  or the legal representative
of any such director,  officer, trustee, employee or agent, shall be indemnified
and held harmless by the registrant to the fullest  extent  permitted by the New
Jersey Business  Corporation  Act, as the same exists or may be amended (but, in
the case of any such amendment,  only to the extent that such amendment  permits
the registrant to provide broader indemnification rights than said Act permitted
prior  to such  amendment),  from  and  against  any and all  reasonable  costs,
disbursements  and attorneys'  fees, and any and all amounts paid or incurred in
satisfaction  of  settlements,  judgments,  fines  and  penalties,  incurred  or
suffered in connection with any such proceeding,  and such indemnification shall
continue  as to a person  who has  ceased to be a  director,  officer,  trustee,
employee or agent and shall inure to the  benefit of his/her  heirs,  executors,
administrators  and assigns;  provided,  however,  that,  the  registrant  shall
indemnify  any  such  person  seeking   indemnification  in  connection  with  a
proceeding  (or part thereof)  initiated by such person only if such  proceeding
(or part thereof) was  specifically  authorized by the Board of Directors of the
registrant.  The  Certificate  of  Incorporation  provides  that  such  right to
indemnification shall be a contract right and shall include the right to be paid
by the registrant the expenses incurred in connection with any proceeding before
the  final  disposition  of  such  proceeding  as  authorized  by the  Board  of
Directors;  provided,  however, that, if the New Jersey Business Corporation Act
so requires,  the payment of such  expenses  before the final  disposition  of a
proceeding  shall be made only upon receipt by the registrant of an undertaking,
by or on behalf of such director,  officer,  employee, or agent to reimburse the
amounts so paid if it is not ultimately  determined that such person is entitled
to be indemnified under the Certificate of Incorporation or otherwise. The right
to  indemnification  and payment of expenses  provided by or granted pursuant to
the Certificate of Incorporation  shall not exclude or be exclusive of any other
rights to which any person may be entitled under a certificate of incorporation,
by-law,  agreement,  vote  of  shareholders  or  otherwise,   provided  that  no
indemnification  shall be made to or on behalf of such  person if a judgment  or
other final


                                      II-2



adjudication adverse to such person establishes that such person has not met the
applicable  standard of conduct required to be met under the New Jersey Business
Corporation Act.

     The  registrant  may  purchase  and  maintain  insurance  on  behalf of any
director,  officer,  employee or agent of the registrant or another corporation,
partnership,  joint venture,  trust,  employee  benefit plan or other enterprise
against any expenses  incurred in any  proceeding and any  liabilities  asserted
against him/her by reason of such person's being or having been such a director,
officer,  employee or agent,  whether or not the registrant would have the power
to  indemnify  such person  against  such  expenses  and  liabilities  under the
provisions of the  Certificate  of  Incorporation  or otherwise.  The registrant
maintains such insurance on behalf of its directors and officers.

     The foregoing  statements are subject to the detailed provisions of the New
Jersey   Business   Corporation   Act  and  the   registrant's   Certificate  of
Incorporation.  The Form of  Underwriting  Agreement  contained  in Exhibit  1.1
provides  for   indemnification  of  the  directors  and  officers  signing  the
Registration Statement and certain controlling persons of the registrant against
certain  liabilities,  including certain liabilities under the Securities Act in
certain instances by the Underwriters.

     For  information  concerning  the  registrant's  undertaking  to  submit to
adjudication the issue of indemnification  for violation of the securities laws,

Item 17.  UNDERTAKINGS.

     The undersigned registrant hereby undertakes:

     (1)  to file,  during any period in which offers or sales are being made, a
post-effective amendment to this registration statement:

          (i) to include any prospectus required by Section 10(a)(3) of the
     Securities Act;


                                       II-4



          (ii) to reflect in the  prospectus  any facts or events  arising after
     the  effective  date of the  registration  statement  (or the  most  recent
     post-effective amendment thereof) which,  individually or in the aggregate,
     represent  a  fundamental  change  in  the  information  set  forth  in the
     registration  statement.  Notwithstanding  the  foregoing,  any increase or
     decrease  in volume of  securities  offered (if the total  dollar  value of
     securities  offered  would not exceed  that which was  registered)  and any
     deviation from the low or high end of the estimated  maximum offering range
     may be  reflected  in the form of  prospectus  filed  with  the  Commission
     pursuant  to Rule  424(b) if, in the  aggregate,  the changes in volume and
     price represent no more than a 20% change in the maximum aggregate offering
     price set  forth in the  "Calculation  of  Registration  Fee"  table in the
     effective registration statement; and

          (iii) to include any material  information with respect to the plan of
     distribution not previously disclosed in the registration  statement or any
     material change to such information in the registration statement;

provided,  however,  that  paragraphs  (1)(i) and (1)(ii)  above do not apply if
information  required  to be  included in a  post-effective  amendment  by those
paragraphs  is  contained  in periodic  reports  filed with or  furnished to the
Commission  by the  registrant  pursuant  to Section 13 or Section  15(d) of the
Securities  Exchange Act of 1934,  as amended  (the  "Exchange  Act"),  that are
incorporated by reference in the registration statement;

     (2) that, for the purpose of determining any liability under the Securities
Act, each such post-effective amendment shall be deemed to be a new registration
statement relating to the securities  offered therein,  and the offering of such
securities  at that time shall be deemed to be the  initial  bona fide  offering
thereof; and

     (3) to remove from registration by means of a post-effective  amendment any
of the securities being registered which remain unsold at the termination of the
offering.

     The  undersigned   registrant  hereby  undertakes  that,  for  purposes  of
determining  any  liability  under  the  Securities  Act,  each  filing  of  the
registrant's  annual  report  pursuant to Section  13(a) or Section 15(d) of the
Exchange Act (and, where  applicable,  each filing of an employee benefit plan's
annual  report   pursuant  to  Section  15(d)  of  the  Exchange  Act)  that  is
incorporated by reference in the registration  statement shall be deemed to be a
new registration  statement relating to the securities offered therein,  and the
offering of such  securities at that time shall be deemed to be the initial bona
fide offering thereof.

     Insofar as indemnification for liabilities arising under the Securities Act
may  be  permitted  to  directors,  officers  and  controlling  persons  of  the
registrant  pursuant  to the  provisions  set forth in  response  to Item 15, or
otherwise,  the  registrant has been advised that in the opinion of the SEC such
indemnification  is against public policy as expressed in the Securities Act and
is,  therefore,  unenforceable.  In the event  that a claim for  indemnification
against such  liabilities  (other than the payment by the registrant of expenses
incurred or paid by a director,  officer or controlling person of the registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director,  officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been  settled by


                                      II-5



controlling  precedent,  submit  to a  court  of  appropriate  jurisdiction  the
question  of whether  such  indemnification  by it is against  public  policy as
expressed in the Securities  Act and will be governed by the final  adjudication
of such issue.

     The undersigned registrant hereby undertakes to file an application for the
purpose of determining  the  eligibility of the trustee to act under  subsection
(a) of Section 310 of the Trust  Indenture Act in accordance  with the rules and
regulations  prescribed by the Commission  under Section  305(b)(2) of the Trust
Indenture Act.


                                      II-6



                                  SIGNATURES

     Pursuant to the  requirements  of the  Securities  Act of 1933, as amended,
Schering-Plough  Corporation certifies that it has reasonable grounds to believe
that it meets all of the requirements for filing on Form S-3 and has duly caused
this  Registration  Statement  to be  signed on its  behalf by the  undersigned,
thereunto duly authorized in the City of Kenilworth, State of New Jersey, on May
11, 2004.
