                DESCRIPTION OF THE PLAN AND THE STOCK OPTIONS

General Information

     A copy of the Plan is filed as an exhibit to the 
Registration Statement of which this Prospectus forms a part.  
The following is a description of the Company's 1997 Stock 
Incentive Plan.  The purpose of the Plan is to aid the Company 
and its subsidiaries and affiliates in securing and retaining key 
employees of outstanding ability and to motivate such employees 
to exert their best efforts on behalf of the Company, its 
subsidiaries and affiliates.

     This description summarizes certain material provisions of 
the Plan, and as such, it does not purport to be complete and is 
qualified in its entirety by reference to the Plan.  Terms used 
herein and not otherwise defined shall have the respective 
meanings set forth in the Plan.

Securities to be Offered

     The Plan was adopted by the Board of Directors on February 
25, 1997 and was approved by the stockholders of the Company on 
April 22, 1997.  The Plan provides for the grant of up to 
36,000,000 Common Shares of the Company through (i) incentive 
stock options ("ISOs") within the meaning of Section 422 of the 
Internal Revenue Code of 1986, as amended (the "Code"), (ii) 
nonstatutory stock options ("NSSOs") not intended to qualify 
under Section 422 of the Code, and (iii) Deferred Stock Unit 
awards (provided that no more than 15,000,000 Common Shares may 
be awarded in the form of Deferred Stock Units). No participant 
may receive a grant of greater than 1,500,000 Common Shares in 
any fiscal year.  Each option granted under the Plan may, at the 
discretion of the Committee, contain provision for limited 
rights, as described below.  All Plan limits have been adjusted 
for a two-for-one stock split on June 3, 1997.

     Common Shares under the Plan may be unissued shares, 
treasury shares or a combination of each.  Any shares subject to 
an award under the Plan that are not issued because they are 
forfeited, and any shares optioned under the Plan that cease to 
be subject to the option, may again be awarded or optioned under 
the Plan.  As of the date of this Prospectus, awards and options 
with respect to 8,800 shares had been granted under the Plan 
(after giving effect to the two-for-one stock split).

Administration of the Plan

     The Plan is administered by the Executive Compensation and 
Organization Committee of the Board of Directors (the 
"Committee"), consisting of at least two members of the Board of 
Directors of the Company.  Members of the Committee are 
nonemployee directors within the meaning of Rule 16b-3 under the 
Securities Exchange Act of 1934, as amended (the "Exchange Act"), 
or any successor definition adopted by the Commission, and an 
"outside director" for purposes of Section 162(m)(4) of the Code. 
 The Committee will determine the provisions and timing of the 
options and awards granted under the Plan, and will interpret the 
Plan and the awards and options granted thereunder.  The 
Committee will generally conduct and administer the Plan and make 
all determinations which may be necessary or advisable in 
connection therewith.  The Committee will also adopt, amend and 
rescind rules and regulations regarding the Plan and its actions 
will be binding on Plan participants.  Committee decisions and 
selections shall be made by a majority of its members present at 
a meeting at which a quorum is present, and shall be final.  Any 
decision or selection reduced to writing and signed by all 
members of the Committee shall be fully effective, as if such 
decision or selection had been made at a meeting duly held.  The 
Committee may delegate some or all of its authority under the 
Plan as the Committee deems appropriate; provided, however, that 
no such delegation may be made that would (i) cause options or 
awards under the Plan to cease to be exempt from Section 16(b) of 
the Exchange Act or (ii) cause a performance-based award to cease 
to qualify for exemption from the deduction limitations under 
Section 162(m) of the Code.

Eligibility

     The Committee, in its sole discretion, will select the 
participants in the Plan and determine the number of shares 
granted to each participant as options or Deferred Stock Unit 
awards.  Employees who are from time to time responsible for the 
performance, growth and protection of the business of the Company 
or its subsidiaries and affiliates, including officers who may 
also be directors of the Company or its subsidiaries or 
affiliates, are eligible to participate in the Plan.  Persons 
serving solely as directors, who are not employees of the 
Company, it's subsidiaries or affiliates, are not eligible to 
participate in the Plan.

Duration of the Plan

     Options and awards under the Plan may not be granted after 
December 31, 2002, but awards or options theretofore granted may 
extend beyond that date.  The Plan may be discontinued by the 
Board of Directors, but no termination may impair the rights of 
any holder of options or awards granted prior thereto.

Amendment of the Plan

     The Board of Directors may alter, amend or discontinue the 
Plan at any time, including without limitation any amendment 
considered to be advisable by reason of changes to the Code.  
However, without the approval of the shareholders, the Board of 
Directors may not (i) increase the total number of Common Shares 
reserved for the purpose of the Plan (except as adjusted for 
changes in capital), (ii) decrease the price at which options may 
be granted to less than 100% of the fair market value on the day 
of the granting of the option except to reflect changes in 
capital and other circumstances specified in the Plan, or (iii) 
extend the duration of the Plan.

     Notwithstanding the foregoing, the Board of Directors may 
amend the Plan and the Committee may amend any option or award, 
either retroactively or prospectively and without the consent of 
any optionee or award holder, so as to preserve or come within 
any exemptions from liability under Section 16(b) of the Exchange 
Act.  The Committee may also substitute new options for 
previously granted options, including previously granted options 
having higher option prices.

Stock Options

     Option Price.  Options granted under the Plan will be either 
ISOs or NSSOs.  The option price per share will be determined by 
the Committee, but shall not be less than 100% of the fair market 
value of a Common Share on the date the option is granted.  "Fair 
market value" shall be the closing price at which shares of such 
stock are traded on the NYSE on the date the option is granted.  
If there is no sale of the shares on the NYSE on the date the 
option is granted, the fair market value of the shares shall be 
the mean between the bid and asked prices on the NYSE at the 
close of the market on the granting date.  In the event the 
method for determining the fair market value shall not be 
practicable, then the Committee may determine the fair market 
value per share by another reasonable method of valuation.

     Payment.  The option price is payable (i) in cash, (ii) in 
Common Shares already owned by the optionee, or (iii) by a 
combination of cash and Common Shares.

     Exercise of Options.  Generally, options may not be 
exercised later than ten years after the date of the grant.  No 
option may be exercised until the optionee has remained in the 
continuous employ of the Company or its subsidiaries and 
affiliates for one year (or if the Committee so determines, for 
at least six months and one day) after the option is granted, 
except in the case of termination of employment because of death 
or permanent disability or a Change of Control (as defined in the 
Plan).  Each option may be exercised by giving written notice to 
the Company specifying the number of shares to be purchased, 
which shall be accompanied by full payment, if any, including any 
applicable taxes.  No option shall be exercised for less than the 
lesser of 100 shares or the full number of shares for which the 
option is exercisable.  No optionee shall have any rights to 
dividends or other rights of a shareholder with respect to shares 
subject to the employee's option until the employee has given 
written notice of exercise of his option, paid in full for such 
shares (including taxes) and met any other terms set with respect 
to such exercise, as described herein.

     Each option granted under the Plan may, at the time of grant 
or subsequent thereto, provide the right either (i) to exercise 
such option in whole or in part without any payment of the option 
price, or (ii) to request the Committee to permit, in its sole 
discretion, such exercise without any payment of the option 
price.  If an option is exercised without a payment of the option 
price, the optionee shall be entitled to receive that number of 
whole shares as is determined by dividing (a) an amount equal to 
the fair market value per share on the date of exercise into (b) 
an amount equal to the excess of the total fair market value of 
the shares on such date with respect to which the option is being 
exercised over the total cash purchase price of such shares as 
set forth in the option.  Fractional shares will be rounded to 
the next lowest whole number.  At the sole discretion of the 
Committee, or as specified in the option, the settlement of all 
or part of an optionee's rights under this provision may be made 
in cash in an amount equal to the fair market value of the shares 
otherwise payable under the Plan.  The number of shares with 
respect to which any option is exercised under this provision 
shall reduce the number of shares thereafter available for 
exercise under the option, and such shares thereafter may not 
again be optioned under the Plan.  In no event may an option be 
exercised at a time when the option price per Common Share of the 
Company equals or exceeds the fair market value per share of such 
Common Share.

     Notwithstanding any intent to grant ISOs, an option will not 
be considered an ISO to the extent that it, together with any 
earlier ISOs granted to any optionee, permits the exercise for 
the first time by such optionee in any calendar year of more than 
$100,000 in value of stock of the Company (determined at the time 
of grant).

     Terms of exercise may differ among participants in the Plan. 
 The Committee may require participants purchasing shares 
pursuant to options to represent and agree with the Company in 
writing that such person is acquiring the shares for investment 
and not with a view to the distribution thereof.  Upon exercise, 
the optionee may elect, in lieu of cash payments, to have his tax 
withholding obligations met by the withholding of Common Shares 
in accordance with rules approved by the Committee.

     With respect to NSSOs, the Plan provides that in the event 
of a Change of Control (as defined in the Plan): (i) each 
outstanding option will immediately become exercisable in full 
and (ii) during the 60-day period following the Change of 
Control, a participant holding an option will have the right to 
surrender all or part of his option to the Company (or its 
successor, if applicable) and receive a cash payment equal to the 
difference between the option price and the Change of Control 
Price (as defined in the Plan).

     Transferability.  Except as described below, no option 
granted pursuant to the Plan may be sold, assigned, transferred, 
pledged, hypothecated or otherwise disposed of, except by will or 
the laws of descent and distribution and, during the lifetime of 
the optionee, may be exercised only by such optionee.  The 
optionee may designate a beneficiary of the option in the event 
of his death by filing a written designation with the Company to 
the attention of Barbara Gray, Stock Plan Administrator (return 
receipt requested), Schering-Plough Corporation, One Giralda 
Farms, Madison, New Jersey 07940-1000.

     The Committee may grant stock options pursuant to the Plan 
that are transferable, or amend outstanding Stock Options granted 
under the Plan to make them transferable, by the optionee to one 
or more members of the optionee's immediate family, to a 
partnership of which the only partners are members of the 
optionee's immediate family, or to a trust established by the 
optionee for the benefit of one or more members of the optionee's 
immediate family.  For this purpose the term "immediate family" 
means the optionee's spouse, parents, children, grandchildren and 
the spouses of such parents, children and grandchildren.  As used 
herein, "Stock Option Transferee" refers to an immediate family 
member of a Plan participant (or such person's beneficiary, 
estate or other legal representative), a partnership of which the 
only partners are members of the optionee's immediate family, a 
trust for the benefit of one or more immediate family members 
that has received Stock Options in a valid transfer, and 
"Participant Transferor" refers to the Plan participant who 
transferred Stock Options held by a particular Stock Option 
Transferee.  No consideration may be paid for the transfer of a 
Stock Option.  Any Stock Option will be treated as an NSSO.

     This Prospectus relates to up to 5,000,000 Common Shares of 
the Company which may be offered and sold to Stock Option 
Transferees pursuant to Stock Options that may be transferred to 
such Stock Option Transferees as described in the immediately 
preceding paragraph.  This Prospectus also relates to the offer 
and sale of Common Shares pursuant to such Stock Options to the 
beneficiaries of such Stock Option Transferees, or the executors, 
administrators or beneficiaries of their estates, or other 
persons duly authorized by law to administer the estate or assets 
of such persons.

     Upon transfer to a Stock Option Transferee, a Stock Option 
continues to be governed by and subject to the terms and 
limitations of the Plan and the relevant grant, and, except as 
described in the next paragraph, the Stock Option Transferee is 
entitled to the same rights as the Participant Transferor 
thereunder, as if no transfer had taken place.  Accordingly, the 
rights of the Stock Option Transferee are subject to the terms 
and limitations of the original grant to the Participant 
Transferor, including provisions relating to expiration date, 
exercisability, exercise price and forfeiture.  For information 
regarding the terms of a particular Stock Option grant, Stock 
Option Transferees should review the grant and may contact 
Barbara Gray, Stock Plan Administrator, Schering-Plough 
Corporation, One Giralda Farms, Madison, New Jersey 07940-1000 
(telephone no. 973-822-7000).

     Once a Stock Option has been transferred to a Stock Option 
Transferee, it may not be subsequently transferred by the Stock 
Option Transferee except by will or the laws of descent and 
distribution.  A Stock Option Transferee may designate in writing 
to the Company before his or her death one or more beneficiaries 
to receive, in the event of his or her death, any rights to which 
the Stock Option Transferee would be entitled under the Plan.  A 
Stock Option Transferee may also designate an alternate 
beneficiary to receive payments if the primary beneficiary 
predeceases the Stock Option Transferee.  A beneficiary 
designation may be changed or revoked in writing by the Stock 
Option Transferee at any time.  Changes in beneficiary 
designation should be sent (return receipt requested) to the 
attention of Barbara Gray, Stock Plan Administrator (return 
receipt requested), Schering-Plough Corporation, One Giralda 
Farms, Madison, New Jersey 07940-1000.

Exercise of Stock Options by Stock Option Transferees

     A Stock Option may be exercised by a Stock Option Transferee 
at any time from the time first set by the Committee in the 
original grant to the Participant Transferor until the close of 
business on the expiration date of the Stock Option (as may be 
affected by the Participant Transferor's employment status as 
described below).

     The purchase price of the shares as to which Stock Options 
are exercised shall be paid to the Company at the time of 
exercise (i) in cash, (ii) by actual or constructive delivery of 
freely transferable Common Shares already owned by the Stock 
Option Transferee for at least six months and having a total fair 
market value on the day prior to the date of exercise at least 
equal to the purchase price, (iii) a combination of cash and 
Common Shares equal in value to the purchase price, or (iv) by 
such other means as the Committee may from time to time 
determine.

     Upon exercise of a Stock Option by a Stock Option 
Transferee, any federal, state or local withholding taxes arising 
from the exercise are the obligation of the Participant 
Transferor or the Participant Transferor's estate, as applicable.

     A Stock Option will be deemed exercised on the date the 
Company has received a copy of the Stock Option Exercise Form (by 
mail or facsimile transmission), completed in all respects and 
signed by the Stock Option Transferee (accompanied by a check, 
Common Shares and/or attestation form as applicable).  The Stock 
Option shares will generally be transferred to the Stock Option 
Transferee as of the day following the date that (i) the above 
conditions have been met, (ii) the funds and/or Common Shares 
paid by the Stock Option Transferee in satisfaction of the 
exercise price have been received by the Company free and clear 
of all restrictions, and (iii) the Company has received 
confirmation that the Participant Transferor's withholding 
obligations have been satisfied.

     Once the exercise is completed as described above, stock 
certificates for the appropriate number of shares will be 
delivered to the Stock Option Transferee or his or her estate or 
beneficiaries, or otherwise delivered in such manner as the 
person(s) entitled thereto may direct.

     Except as specifically provided in the Plan, no person shall 
have the right to assign, transfer, alienate, pledge, encumber or 
subject to lien the benefits to which he is entitled thereunder, 
and the benefits under the Plan shall not be subject to adverse 
legal process of any kind.  No prohibited assignment, transfer, 
alienation, pledge or encumbrance of benefits or subjection of 
benefits to lien or adverse legal process of any kind will be 
recognized by the Committee and in such case the Committee may 
terminate the right of such person to such benefits and direct 
that they be held or applied for the benefit of such person, his 
spouse, children or other dependents in such manner and in such 
proportion as the Committee deems advisable.  If, in the judgment 
of the Committee, the person to whom benefits are due under the 
Plan becomes physically or mentally incompetent, the Committee 
shall have the right to determine to whom such benefits shall be 
paid for the benefit of such person.

     Termination.  Because Stock Options transferred to Stock 
Option Transferees continue to be governed by the terms of the 
Plan and the original grant, their exercisability continues to be 
affected by the Participant Transferor's employment status.  In 
addition to terminating upon exercise and upon expiration of the 
stated term of the option, each option shall terminate at such 
time after termination of a participant's employment as set forth 
below.  Options may provide for different termination dates or 
other related provisions for the option depending on the cause of 
termination of employment.

     Except as set forth below, an option may only be exercised 
during a participant's employment with the Company or its 
subsidiaries or during the three months following termination of 
employment for any reason other than death, permanent disability 
or retirement.  After termination of a participant's employment 
with the Company or any of its subsidiaries on account of death 
or permanent disability, options generally may be exercised at 
any time during the stated option period, regardless of whether 
they were exercisable at the time of such termination.  After a 
participant retires from the Company or any of its subsidiaries, 
the participant's options generally may thereafter be exercised 
to the extent to which they were exercisable at the time of the 
participant's retirement (unless the Committee, in its 
discretion, determines otherwise), and may be exercised at any 
time during the stated period.  In the event of the participant's 
death prior to the expiration of the option period following 
termination of employment for permanent disability or retirement, 
options generally may be exercised during the stated option 
period.  An option may not be exercised after the expiration of 
the stated period of the option, except that if the participant 
dies within one year prior to the expiration date, any NSSOs may 
be exercised for a minimum of one year from the date of death.

     If an employee is terminated for cause, all options held by 
the employee under the Plan shall be immediately forfeited and 
the employee will be liable to the Company for all profit 
realized by him from options exercised during the three months 
immediately preceding such termination.



Changes in Capital

     If the outstanding Common Shares of the Company subject to 
the Plan shall at any time be changed or exchanged by declaration 
of a stock dividend, stock split, combination of shares, 
recapitalization, merger, consolidation or other corporate 
reorganization in which the Company is the surviving corporation, 
or if the Company shall pay an extraordinary dividend on its 
Common Shares, the number and kind of shares subject to the Plan 
and/or the number of Units or option values or prices shall be 
appropriately and equitably adjusted so as to maintain the value 
or option price thereof, as the case may be.

                     FEDERAL INCOME TAX CONSEQUENCES

     Prior to making a transfer of a Transferable Option, a 
participant should consult with his or her personal tax advisors 
concerning the possible Federal and state gift, estate, 
inheritance, and generation skipping tax consequences of such a 
transfer, as well as state and local income tax consequences 
which are not addressed herein.  The discussion of federal income 
tax consequences for the Participant Transferor and the Stock 
Option Transferee set forth below assumes that the Transferable 
Option does not have a readily ascertainable fair market value at 
the date of grant and that the transfer of a Transferable Option 
during a participant's lifetime is made by way of gift and no 
consideration is received therefor.

     Federal Income Tax Consequences for Participant Transferors. 
 A Participant Transferor who transfers a Transferable Option by 
way of gift to an immediate family member or a trust for the 
benefit of an immediate family member or a partnership in which 
only immediate family members are partners will not recognize 
income at the time of the transfer.  Instead, at the time the 
Stock Option Transferee exercises the Transferable Option, the 
Participant Transferor will generally recognize ordinary 
compensation income in an amount equal to the excess of the fair 
market value of the shares purchased over the exercise price.  
(Special rules may apply to participants subject to potential 
liability under Section 16(b) of the Exchange Act, which may 
defer the recognition of compensation income.)  Moreover, such 
income will be subject to payment and withholding of income and 
FICA taxes.  Normally, Participant Transferors may satisfy the 
withholding obligation by writing a check to the Company or by 
another method permitted by the Company.  Subject to certain 
limitations, the Company will generally be entitled to claim a 
federal income tax deduction at such time and in the same amount 
that the Participant Transferor recognizes ordinary income.  In 
the event the Stock Option Transferee exercises the Transferable 
Option after the death of the Participant Transferor, any such 
ordinary income will generally be recognized by the Participant 
Transferor's estate.

     Federal Income Tax Consequences for Stock Option Transferee. 
 A Stock Option Transferee will not recognize income at the time 
of the transfer of the Transferable Option.  As described in the 
preceding paragraph, the Participant Transferor (or the estate of 
the Participant Transferor, as the case may be) and not the Stock 
Option Transferee will generally recognize ordinary compensation 
income at the time the Stock Option Transferee exercises the 
Transferable Option.  A Stock Option Transferee who chooses to 
exercise a Transferable Option in whole or in part by delivery of 
other Common Shares already owned by the Stock Option Transferee 
should consult with his or her own tax advisor concerning the tax 
consequences of such a transaction.

     Federal Income Tax Consequences on Subsequent Sale of Stock. 
 If shares acquired upon exercise of a Transferable Option are 
later sold or exchanged, then the difference between the sales 
price and the Stock Option Transferee's tax basis for the shares 
will generally be taxable as long-term or short-term capital gain 
or loss (if the stock is a capital asset of the Stock Option 
Transferee) depending upon whether the stock has been held for 
more than one year after the exercise date.  The tax basis for 
the shares in the hands of the Stock Option Transferee would be 
the exercise price for the Transferable Option plus the amount of 
the income recognized by the Participant Transferor (or the 
estate of the Participant Transferor, as the case may be) at the 
time of exercise.


                                LEGAL MATTERS

     The validity of the Common Shares offered in this Prospectus 
will be passed upon for the Company by William J. Silbey, 
Secretary of the Company, One Giralda Farms, Madison, New Jersey 
07940-1000.  Skadden, Arps, Slate, Meagher & Flom LLP has advised 
the Company concerning certain federal income tax consequences 
related to Stock Options under the Plan and the transfer and 
exercise thereof.

Item 15.  Indemnification of Directors and Officers

     The New Jersey Business Corporation Act provides that a New 
Jersey corporation has the power to indemnify a director or 
officer against his or her expenses and liabilities in connection 
with any proceeding involving the director or officer by reason 
of his or her being or having been such a director or officer, 
other than a proceeding by or in the right of the corporation, if 
such a director or officer acted in good faith and in a manner he 
or she reasonably believed to be in or not opposed to the best 
interests of the corporation; and with respect to any criminal 
proceeding, such director or officer had no reasonable cause to 
believe his or her conduct was unlawful.

     The indemnification and advancement of expenses shall not 
exclude any 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 or officer 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 a director or 
officer if a judgment or other final adjudication adverse to the 
director or officer establishes that his or her acts or omissions 
(a) were in breach of his or her duty of loyalty to the 
corporation or its shareholders, (b) were not in good faith or 
involved a knowing violation of law or (c) resulted in receipt by 
the director or officer of an improper personal benefit.

     The Registrant's Certificate of Incorporation provides that, 
directors and officers of the Registrant shall not be personally 
liable 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 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 or 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 or 
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 or 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 right to 
indemnification created by the Certificate of Incorporation shall 
be a contract right and shall include the right to be paid by the 
Registrant the expenses incurred in connection with any 
proceeding in advance of 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 in advance of 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 repay all amounts so advanced unless it 
shall ultimately be determined that such person is entitled to be 
indemnified under the Certificate of Incorporation or otherwise. 
 The right to indemnification and advancement 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 
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 any and liabilities asserted against him or 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.

Item 17.  Undertakings

          (a) 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)  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;

                 (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 (a)(1)(i) and 
(a)(1)(ii) do not apply if the information required to 
be included in a post-effective amendment by those 
paragraphs is contained in periodic reports filed 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.

             (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.

        (b)  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.

        (c)  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 
foregoing provisions, 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 controlling 
precedent, submit to a court of appropriate jurisdiction the 
question 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.



                              SIGNATURES

     Pursuant to the requirements of the Securities Act of 1933, 
the Registrant has duly caused this Registration Statement to be

RE:   Schering-Plough Corporation
      Registration Statement on Form S-3

Gentlemen:

     As Secretary of Schering-Plough Corporation, a New 
Jersey corporation (the "Corporation"), I have examined the 
Certificate of Incorporation and Bylaws of the Corporation as 
well as such other documents and proceedings as I have 
considered necessary for the purposes of this opinion.  I 
have also examined and am familiar with the Corporation's 
Registration Statement on Form S-3 (the "Registration 
Statement") as filed with the Securities and Exchange 
Commission under the Securities Act of 1933, relating to 
5,000,000 shares of the Corporation's Common Shares, par 
value $1.00 per share (the "Common Shares") which may be 
offered or sold to immediate family members of certain 
participants in the Corporation's 1997 Stock Incentive Plan 
(the "Plan"), pursuant to nonqualified stock options (the 
"Stock Options") granted to such participants under the Plan, 
some or all of which may be transferred by participants to 
immediate family members in accordance with the Plan and the 
grant documents specifying the terms and conditions of such 
Stock Options.

     Based upon the foregoing, and having regard to legal 
considerations which I deem relevant, I am of the opinion 
that the Common Shares have been duly authorized by the 
Corporation and, when (a) issued and delivered by the 
Corporation in accordance with the terms of the Plan and (b) 
paid for in full in accordance with the terms of the Plan, 
the Common Shares will be legally issued, fully paid and non-
assessable.

     This opinion is limited to the general corporation laws 
of the State of New Jersey and the federal law of the United 
States, and I do not express any opinion herein concerning 
any other law.  This opinion is intended solely for the 
Corporation's use in connection with the registration of the 
Common Shares and may not be relied upon for any other 
purpose or by any other person.  This opinion may not be 
quoted in whole or in part or otherwise referred to or 
furnished to any other person except in response to a valid 
subpoena.  This opinion is limited to the matters expressly 
stated herein, and no opinion is implied or may be inferred 
beyond the matters expressly stated herein.  This opinion is 
rendered as of the date hereof, and I assume no obligation to 
update or supplement such opinion to reflect any facts or 
circumstances that may hereafter come to my attention or any 
changes in facts or law that may hereafter occur.  I hereby 
consent to the inclusion of this opinion letter as an exhibit 
to the Registration Statement.

                                       Very truly yours,

                                       /s/ William J. Silbey

P.O. Box 1000
Madison, New Jersey  07940-1000

Dear Sirs:

     We have acted as counsel for Schering-Plough 
Corporation, a New Jersey corporation (the "Company"), in 
connection with certain federal income tax issues relating to 
transferable options ("Options") to acquire shares of Common 
Stock, par value $1.00 per share (the "Common Stock"), of the 
Company, which Options have been or may be granted in 
accordance with the terms of the Schering-Plough Corporation 
1997 Stock Incentive Plan (the "Plan").  It is expected that 
an aggregate of 5,000,000 shares of Common Stock which may be 
acquired by transferees upon exercise of the Options will be 
registered with the Securities and Exchange Commission in 
June, 1997, pursuant to a filing under the Securities Act of 
1933, as amended, of a Registration Statement on Form S-3 
(the "Registration Statement").  In connection with this 
opinion, we have examined the Plan, the "Federal Income Tax 
Consequences" section of the prospectus (the "Prospectus") 
relating to the Registration Statement, and such other 
documents as we have deemed necessary or appropriate.

     Based on the foregoing, we advise you that, in our 
opinion, under current law, the discussion set forth under 
the heading "Federal Income Tax Consequences" in the 
Prospectus, although general in nature, is an accurate 
summary of certain federal income tax consequences related to 
Options which have been transferred under the Plan.

     We consent to the filing of this opinion as an exhibit 
to the Registration Statement and to the use of our name 
wherever appearing in the Registration Statement and any 
amendment thereto.

                                        Very truly yours,


                                    /s/ Skadden, Arps, Slate,
                                        Meagher & Flom LLP
