                          AGREEMENT AND PLAN OF MERGER

          THIS AGREEMENT AND PLAN OF MERGER, dated as of May 3, 1995, is by
and among Marion Merrell Dow Inc., a Delaware corporation (the "Company"),
The Dow Chemical Company, a Delaware corporation ("DCC"), Hoechst
Corporation, a Delaware corporation ("Parent"), and H Pharma Acquisition
Corp., a Delaware corporation ("Acquisition").

          WHEREAS, the Boards of Directors of Parent, Acquisition, DCC and
the Company have each approved the acquisition of the Company by Parent
upon the terms and subject to the conditions set forth in this Agreement;

          WHEREAS, in furtherance thereof, upon the terms and subject to
the conditions of this Agreement, (i) Acquisition would be merged (the
"Merger") with and into the Company in accordance with the General
Corporation Law of the State of Delaware ("Delaware Law") and (ii) each
share of common stock, par value $0.10 per share, of the Company (the
"Shares"), issued and outstanding immediately prior to the Effective Time
(as defined herein) would, except as otherwise expressly provided herein,
be converted into the right to receive the Merger Consideration (as defined
herein); and

          WHEREAS, simultaneously with the execution and delivery hereof,
Parent, Acquisition, DCC, RH Acquisition Corp., a Delaware corporation and
a wholly owned subsidiary of DCC ("RHAC"), and Dow Holdings Inc., a
Delaware corporation and a wholly owned subsidiary of DCC ("DHI" and,
collectively with DCC and RHAC, "Dow") are entering into a stock purchase
agreement (the "Stock Purchase Agreement") pursuant to which Dow has
agreed, among other things, to sell to Acquisition all of the 196,865,790
Shares held by Dow (the "Dow Shares").

          NOW, THEREFORE, in consideration of the foregoing and the mutual
covenants and agreements herein contained, and intending to be legally
bound hereby, the Company, DCC, Parent and Acquisition hereby agree as
follows.
                                   ARTICLE I

                                   THE MERGER

          Section 1.1  THE MERGER.  At the Effective Time and upon the
terms and subject to the conditions of this Agreement and Delaware Law,
Acquisition shall be merged with and into the Company, whereupon the
separate corporate existence of Acquisition shall cease and the Company
shall continue as the surviving corporation (the "Surviving Corporation"). 
At Acquisition's option, subject to Section 9.2 hereof, the Merger may be
structured so that any direct subsidiary of Parent other than Acquisition
is merged with and into the Company.  In the event of such election, the
parties agree to execute an appropriate amendment to this Agreement in
order to reflect such election.

          Section 1.2  EFFECTIVE TIME; CLOSING.  As soon as practicable
after the satisfaction or waiver of the conditions set forth in Article
VII, the parties hereto will file a certificate of merger with the
Secretary of State of the State of Delaware and make all other filings or
recordings required by Delaware Law in connection with the Merger.  The
Merger shall become effective at such time as the certificate of merger is
duly filed with the Secretary of State of the State of Delaware (the
"Effective Time").  Prior to such filing, a closing (the "Closing") shall 
<PAGE>                                                                6
be held at the offices of Skadden, Arps, Slate, Meagher & Flom, 919 Third
Avenue, New York, New York 10022, or such other place as the parties shall
agree, for the purpose of confirming the satisfaction or waiver of the
conditions set forth in Article VII.  The date on which the Closing occurs
is referred to herein as the "Closing Date".

          Section 1.3  EFFECTS OF THE MERGER; SUBSEQUENT ACTIONS.  (a) The
Merger shall have the effects set forth in Delaware Law.  Without limiting
the generality of the foregoing, and subject thereto and any other
applicable laws, at the Effective Time, all the properties, rights,
privileges, powers and franchises of the Company and Acquisition shall vest
in the Surviving Corporation, and all debts, liabilities, restrictions,
disabilities and duties of the Company and Acquisition shall become the
debts, liabilities, restrictions, disabilities and duties of the Surviving
Corporation.

               (b)  If, at any time after the Effective Time, the Surviving
Corporation shall consider or be advised that any deeds, bills of sale,
assignments, assurances or any other actions or things are necessary or
desirable to vest, perfect or confirm of record or otherwise in the
Surviving Corporation its right, title or interest in, to or under any of
the rights, properties or assets of the Company or Acquisition acquired or
to be acquired by the Surviving Corporation as a result of or in connection
with the Merger, or otherwise to carry out this Agreement, the officers and
directors of the Surviving Corporation shall be authorized to execute and
deliver, in the name and on behalf of the Company or Acquisition, all such
deeds, bills of sale, assignments, assumption agreements and assurances and
to take and do, in the name and on behalf of each of such corporations or
otherwise, all such other actions and things as may be necessary or
desirable to vest, perfect or confirm any and all right, title and interest
in, to and under such rights, properties or assets of the Surviving
Corporation or otherwise to carry out this Agreement.

          Section 1.4  CERTIFICATE OF INCORPORATION AND BY-LAWS.  (a) The
Certificate of Incorporation of Acquisition in effect immediately prior to
the Effective Time shall be the Certificate of Incorporation of the
Surviving Corporation until amended in accordance with applicable law;
PROVIDED that the name of the Surviving Corporation as set forth in its
Certificate of Incorporation shall be changed to a new name to be
determined by Acquisition prior to the Effective Time.

               (b)  The By-Laws of Acquisition in effect at the Effective
Time shall be the By-Laws of the Surviving Corporation until amended in
accordance with applicable law.

          Section 1.5  DIRECTORS.  The directors of Acquisition at the
Effective Time shall be the initial directors of the Surviving Corporation,
each to hold office in accordance with the Certificate of Incorporation and
By-Laws of the Surviving Corporation and until his or her successor is duly

          Section 1.7  CONVERSION OF SHARES.  At the Effective Time, by
virtue of the Merger and without any action on the part of Parent,
Acquisition, the Company or the holder of any of the following securities:

               (a)  Each Share issued and outstanding immediately prior to
the Effective Time (other than Shares to be cancelled pursuant to Section
1.7(b) hereof and Dissenting Shares (as hereinafter defined)), shall by
virtue of the Merger and without any action on the part of the holder
thereof be converted into the right to receive the Merger Consideration (as
defined below), without interest thereon.  As used herein, "Merger
Consideration" means the sum (rounded up to the nearest $0.01) of $25.75 in
cash plus an Additional Contingent Amount (as defined below); PROVIDED,
that the Additional Contingent Amount shall be payable only if Acquisition,
Parent or their affiliates purchase the Dow Shares at least one (1) day
prior to the Effective Time.  As used herein, "Additional Contingent
Amount" means a cash amount equal to $0.25 multiplied by a fraction (i) the
numerator of which shall be the number of whole days from the record date
for the regular quarterly cash dividend on the Shares next preceding the
date on which the Effective Time occurs (excluding such record date) to and
including the date on which the Effective Time occurs and (ii) the
denominator of which shall be the number of whole days in the full quarter
during which the Effective Time occurs.

               (b)  Each Share which is issued and outstanding immediately
prior to the Effective Time and owned by Parent or Acquisition or any
direct or indirect subsidiary of Parent or Acquisition, or which is held in
the treasury of the Company or any of its subsidiaries, shall be cancelled
and retired and no payment of any consideration shall be made with respect
thereto.

               (c)  Each share of Common Stock, par value $0.01 per share,
of Acquisition issued and outstanding immediately prior to the Effective
Time shall be converted into and become one validly issued, fully paid and
nonassessable share of Common Stock, par value $0.01 per share, of the
Surviving Corporation.

          Section 1.8  COMPANY PLANS.  (a) Effective as of the Effective
Time, each outstanding option (including any related stock appreciation
right)(an "Employee Option") issued, awarded or granted pursuant to the
Company's 1992 Incentive Compensation Plan, the 1985 Associate Stock Option
Plan or the Non-Qualified Employee Stock Option Plan (the "Company Plans")
to purchase Shares shall be eliminated by the Company, and each holder of
an eliminated Employee Option shall be entitled to receive from the Company
(or, at Parent's option, any subsidiary of the Company) in consideration
for the elimination of such Employee Option an amount in cash (less
applicable withholding Taxes (as defined in Section 3.10 hereof)) equal to
the product of (i) the number of Shares previously subject to such Employee
Option and (ii) the excess, if any, of the Merger Consideration over the
exercise price per Share previously subject to such Employee Option;
PROVIDED, that each Employee Option the exercise price per Share of which
is equal to or greater than the Merger Consideration shall be eliminated in
consideration for a cash payment equal to the product of $0.01 multiplied
by the number of Shares previously subject to such Employee Option. 

               (b)  Each outstanding performance share ("Performance
Share") granted under the Company's 1992 Incentive Compensation Plan (the
"Incentive Plan") shall become fully vested in accordance with the terms of
the Incentive Plan and, effective as of the Effective Time, shall, unless 

<PAGE>                                                                8
theretofore paid and eliminated in accordance with the terms thereof, be
eliminated by the Company, and each holder of an eliminated Performance
Share shall be entitled to receive from the Company (or, at Parent's
option, any subsidiary of the Company) an amount in cash (less applicable
withholding Taxes) equal to the product of (i) the Merger Consideration and
(ii) the number of Performance Shares previously held by such holder.

          Section 1.9  STOCKHOLDERS' MEETING.  The Company, acting through
its Board of Directors (the "Board"), shall in accordance with applicable
law as soon as practicable following the date hereof:

                    (i)  subject to applicable law, duly call, give notice
of, convene and hold an annual or special meeting of its stockholders (the
"Stockholders' Meeting") for the purpose of considering and taking action
upon this Agreement;

                    (ii)  subject to the fiduciary duties of the Board
under applicable law, include in the Proxy Statement (as defined in Section
3.7) the recommendation of the Board that stockholders of the Company vote
in favor of adoption of this Agreement and the transactions contemplated
hereby; and

                    (iii)  subject to the fiduciary duties of the Board
under applicable law, use its reasonable best efforts to obtain the
necessary approvals by its stockholders of this Agreement and the
transactions contemplated hereby.

          At such meeting, each of DCC, Parent and Acquisition will vote
(and will cause each of their respective affiliates to vote) all Shares
owned by it (or their respective affiliates) in favor of adoption of this
Agreement and the transactions contemplated hereby.

                                   ARTICLE II

                     DISSENTING SHARES; EXCHANGE OF SHARES

          Section 2.1  DISSENTING SHARES.  Notwithstanding anything in this
Agreement to the contrary, Shares outstanding immediately prior to the
Effective Time and held by a holder who has not voted in favor of the
Merger or consented thereto in writing and who has demanded appraisal for
such Shares in accordance with Section 262 of Delaware Law ("Dissenting
Shares") shall not be converted into a right to receive the Merger
Consideration unless such holder fails to perfect or withdraws or otherwise
loses his right to appraisal.  If, after the Effective Time, such holder
fails to perfect or withdraws or loses his right to appraisal, such Shares
shall be treated as if they had been converted as of the Effective Time
into a right to receive the Merger Consideration without interest thereon. 
The Company shall give Acquisition prompt notice of any demands received by
the Company for appraisal of Shares, and, prior to the Effective Time,
Acquisition shall have the right to participate in all negotiations and
proceedings with respect to such demands.  Prior to the Effective Time, the
Company shall not, except with the prior written consent of Acquisition,
make any payment with respect to, or settle or offer to settle, any such
demands.

          Section 2.2  EXCHANGE OF CERTIFICATES.  (a) Prior to the
Effective Time, Parent shall designate a bank or trust company reasonably
acceptable to the Company to act as paying agent (the "Paying Agent") in
effecting the exchange for the Merger Consideration of certificates (the

<PAGE>                                                                9
Certificates") that, prior to the Effective Time, represented Shares.  Upon
the surrender of each such Certificate formerly representing Shares,
together with a properly completed letter of transmittal, the Paying Agent
shall pay the holder of such Certificate the Merger Consideration
multiplied by the number of Shares formerly represented by such
Certificate, in exchange therefor, and such Certificate shall forthwith be
cancelled.  Until so surrendered and exchanged, each such Certificate
(other than Certificates representing Dissenting Shares or Shares held by
Parent, Acquisition or the Company, or any direct or indirect subsidiary
thereof) shall represent solely the right to receive the Merger
Consideration.  No interest shall be paid or accrue on the Merger
Consideration.  If the Merger Consideration (or any portion thereof) is to
be delivered to any person other than the person in whose name the
Certificate formerly representing Shares surrendered in exchange therefor
is registered, it shall be a condition to such exchange that the
Certificate so surrendered shall be properly endorsed or otherwise be in
proper form for transfer and that the person requesting such exchange shall
pay to the Paying Agent any transfer or other Taxes required by reason of
the payment of the Merger Consideration to a person other than the
registered holder of the Certificate surrendered, or shall establish to the
satisfaction of the Paying Agent that such Tax has been paid or is not
applicable.

               (b)  Prior to the Effective Time, Parent or Acquisition
shall deposit, or cause to be deposited, in trust with the Paying Agent the
Merger Consideration to which holders of Shares shall be entitled at the
Effective Time pursuant to Section 1.7(a) hereof; PROVIDED that no such
deposit shall relieve Parent of its obligation to pay the Merger
Consideration pursuant to Section 1.7(a). 

               (c)  The Merger Consideration shall be invested by the
Paying Agent, as directed by Parent, provided such investments shall be
limited to direct obligations of the United States of America, obligations
for which the full faith and credit of the United States of America is
pledged to provide for the payment of principal and interest, commercial
paper rated of the highest quality by Moody's Investors Services, Inc. or
Standard & Poor's Corporation, or certificates of deposit issued by a
commercial bank having at least $1,000,000,000 in assets; PROVIDED, that no
loss on investment made pursuant to this Section 2.2(c) shall relieve
Parent or Acquisition of its obligation to pay the Merger Consideration
pursuant to Section 1.7(a).

               (d)  Promptly following the date which is six months after
the Effective Time, the Paying Agent shall deliver to Parent all cash and
documents in its possession relating to the transactions described in this
Agreement, and the Paying Agent's duties shall terminate.  Thereafter, each
holder of a Certificate formerly representing a Share may surrender such
Certificate to the Surviving Corporation and (subject to applicable
abandoned property, escheat and similar laws) receive in exchange therefor
the Merger Consideration, without any interest thereon.

               (e)  Promptly after the Effective Time, the Paying Agent
shall mail to each record holder of Certificates that immediately prior to
the Effective Time represented Shares a form of letter of transmittal and
instructions for use in surrendering such Certificates and receiving the
Merger Consideration in exchange therefor.



<PAGE>                                                                10
               (f)  After the Effective Time, there shall be no transfers
on the stock transfer books of the Surviving Corporation of any Shares. 
If, after the Effective Time, Certificates formerly representing Shares are
presented to the Surviving Corporation or the Paying Agent, they shall be
cancelled and exchanged for the Merger Consideration, as provided in this
Article II, subject to applicable law in the case of Dissenting Shares.


                                  ARTICLE III

                 REPRESENTATIONS AND WARRANTIES OF THE COMPANY

          The Company represents and warrants to Parent and Acquisition as
follows:

          Section 3.1  ORGANIZATION AND QUALIFICATION; SUBSIDIARIES.  
(a)  Each of the Company and its subsidiaries is a corporation duly
organized, validly existing and in good standing under the laws of the
jurisdiction of its incorporation and has all requisite corporate power and
authority to own, lease and operate its properties and to carry on its
business as now being conducted, except where the failure to be so
organized, existing and in good standing or to have such power and
authority would not, individually or in the aggregate, have a material
adverse effect on the business, results of operations (on an annualized
basis) or financial condition of the Company and its subsidiaries, taken as
a whole (a "Material Adverse Effect").  Without limiting the generality of
the foregoing definition of "Material Adverse Effect", such definition
shall specifically include adverse consequences to earnings or financial
condition in excess of $75 million to the Company and its subsidiaries,
taken as a whole, but shall specifically exclude adverse consequences to
earnings and financial condition of $75 million or less unless such adverse
consequences also constitute a material adverse effect on the business,
results of operations (on an annualized basis) or financial condition of
the Company and its subsidiaries, taken as a whole.  "Material Adverse
Effect" shall not mean or include any of the events set forth on Schedule
3.1(a) or any of the transactions effected pursuant to this Agreement.

               (b)  Each of the Company and its subsidiaries is duly
qualified or licensed and in good standing to do business in each
jurisdiction (including any foreign country) in which the property owned,
leased or operated by it or the nature of the business conducted by it
makes such qualification or licensing necessary, except where the failure
to be so duly qualified or licensed and in good standing would not,
individually or in the aggregate, have a Material Adverse Effect.

               (c)  The Company has heretofore furnished or made available
to Parent complete and correct copies of the Company's Restated Certificate
of Incorporation and By-Laws and the equivalent organizational documents of
each of its subsidiaries, each as amended to the date hereof, as requested
by Parent.  Such Restated Certificate of Incorporation, By-Laws and
equivalent organizational documents are in full force and effect.  The
Company is not in violation of any of the provisions of its Restated
Certificate of Incorporation or By-Laws and no subsidiary of the Company is
in violation of any of the provisions of such subsidiary's equivalent
organizational documents.

               (d)  The Company has heretofore furnished or made available
to Parent a complete and correct list of the subsidiaries of the Company,
which list sets forth the amount of capital stock of or other equity
<PAGE>                                                                11
interests in such subsidiaries owned by the Company, directly or
indirectly.  Except as set forth in Schedule 3.1(d), no entity in which the
Company owns, directly or indirectly, less than a 50% equity interest is,
individually or when taken together with all other such entities, material
to the business of the Company and its subsidiaries, taken as a whole.

          Section 3.2  CAPITALIZATION OF THE COMPANY AND ITS SUBSIDIARIES.

obligations hereunder and under the Restated Certificate of Incorporation
of the Company to redeem the Series A Preferred Shares.  Except as set
forth in Schedule 3.2, each of the outstanding shares of capital stock of
each of the Company's subsidiaries is duly authorized, validly issued,
fully paid and nonassessable and is directly or indirectly owned by the
Company, free and clear of all security interests, liens, claims, pledges,
charges, voting agreements or other encumbrances of any nature whatsoever
(collectively, "Liens").  Except as set forth in Schedule 3.2, there are no
existing options, calls or commitments of any character relating to the
issued or unissued capital stock or other equity securities of any

          Section 3.3  AUTHORITY RELATIVE TO THIS AGREEMENT; FAIRNESS
OPINION.  The Company has all necessary corporate power and authority to
execute and deliver this Agreement, to perform its obligations hereunder
and to consummate the transactions contemplated hereby.  The Board, at a
meeting duly called and held on May 3, 1995,  (i) determined that this
Agreement and the transactions contemplated hereby, including the Merger,
are in the best interests of the stockholders of the Company (other than
DCC, Parent, Acquisition or their affiliates), (ii) approved this Agreement
and the transactions contemplated hereby, including the Merger, (iii)
resolved, subject to their fiduciary duties under applicable law, to
<PAGE>                                                                12
recommend that the stockholders of the Company approve and adopt this
Agreement and the Merger and (iv) resolved to redeem, effective immediately
prior to the Merger, all of the outstanding Series A Preferred Shares. 
Lehman Brothers Inc. ("Lehman Brothers") has delivered to the Board its
written opinion dated May 3, 1995 to the effect that, as of the date of
such opinion, the consideration to be received by the holders of Shares
(other than DCC, Parent, Acquisition or their affiliates) pursuant to the
Merger is fair to such holders from a financial point of view.  As of the
date hereof, the Company has been authorized by Lehman Brothers to permit
the inclusion of such fairness opinion in the Proxy Statement referred to
in Section 3.7.  The execution, delivery and performance of this Agreement
and the consummation of the transactions contemplated hereby have been duly
and validly authorized by the Board and no other corporate proceedings on
the part of the Company are necessary to authorize this Agreement or to
consummate the transactions so contemplated (other than, with respect to
the Merger, the approval and adoption of this Agreement by the holders of a
majority of the outstanding Shares and Series A Preferred Shares (voting
together as a single class) and the filing of the appropriate merger
documents as required by Delaware Law).  The Board has taken all action
necessary with respect to the transactions contemplated hereby and by the
Stock Purchase Agreement so as to render inapplicable to such transactions,
including, without limitation, the Merger and the purchase of Shares
pursuant to the Stock Purchase Agreement, the restrictions on business
combinations contained in Section 203 of the Delaware Law and the
supermajority voting requirements contained in Article Fifteenth of the
Company's Restated Certificate of Incorporation.  This Agreement has been
duly and validly executed and delivered by the Company and, assuming it
constitutes a valid and binding agreement of the other parties hereto,
constitutes a legal, valid and binding agreement of the Company enforceable
against the Company in accordance with its terms. 

          Section 3.4  NON-CONTRAVENTION; REQUIRED FILINGS AND CONSENTS. 
(a) Except as set forth in Schedule 3.4, the execution, delivery and
performance by the Company of this Agreement and the consummation of the
transactions contemplated hereby (including the Merger) do not and will not
(i) contravene or conflict with the Restated Certificate of Incorporation
or By-Laws of the Company or the equivalent organizational documents of any
of its subsidiaries; (ii) assuming that all consents, authorizations and
approvals contemplated by subsection (b) below have been obtained and all
filings described therein have been made, contravene or conflict with or
constitute a violation of any provision of any law, regulation, judgment,
injunction, order or decree binding upon or applicable to the Company, any
of its subsidiaries or any of their respective properties; (iii) conflict
with, or result in the breach or termination of any provision of or
constitute a default (with or without the giving of notice or the lapse of
time or both) under, or give rise to any right of termination,
cancellation, or loss of any benefit to which the Company or any of its
subsidiaries is entitled under any provision of any agreement, contract,
license or other instrument binding upon the Company, any of its
subsidiaries or any of their respective properties, or allow the
acceleration of the performance of, any obligation of the Company or any of
its subsidiaries under any indenture, mortgage, deed of trust, lease,
license, contract, instrument or other agreement to which the Company or
any of its subsidiaries is a party or by which the Company or any of its
subsidiaries or any of their respective assets or properties is subject or
bound; or (iv) result in the creation or imposition of any Lien on any
asset of the Company or any of its subsidiaries, except in the case of
clauses (ii), (iii) and (iv) for any such contraventions, conflicts,
violations, breaches, terminations, defaults, cancellations, losses,
<PAGE>                                                                13
accelerations and Liens which would not individually or in the aggregate
have a Material Adverse Effect or be reasonably expected to prevent the
consummation by the Company of the transactions contemplated by this
Agreement. 

               (b)  The execution, delivery and performance by the Company
of this Agreement and the consummation of the transactions contemplated
hereby (including the Merger) by the Company require no action by or in
respect of, or filing with, any governmental body, agency, official or
authority (either domestic or foreign) other than (i) the filing of a
certificate of merger in accordance with Delaware Law; (ii) compliance with
any applicable requirements of the Hart-Scott-Rodino Antitrust Improvements
Act of 1976, as amended (the "HSR Act"), Regulation (EEC) No. 4064/89 of
the European Community (the "EC Merger Regulation"), and the Canadian
Competition Act; (iii) the filing of a notice pursuant to Section 721 of
the Defense Production Act of 1950, as amended ("Exon-Florio"); (iv)
compliance with any applicable requirements of the Securities Exchange Act
of 1934, as amended (the "Exchange Act"), and state securities, takeover
and Blue Sky laws; and (v) such actions or filings which, if not taken or
made, would not individually or in the aggregate have a Material Adverse
Effect or be reasonably expected to prevent the consummation by the Company
of the transactions contemplated by this Agreement.

          Section 3.5  SEC REPORTS.  (a) The Company has filed all required
forms, reports and documents with the Securities and Exchange Commission
(the "SEC") since January 1, 1992.  The Company has made available to

Form 10-K for the fiscal years ended December 31, 1994, 1993 and 1992, (ii)

other reports or registration statements (other than reports on Form 10-Q
not referred to in (ii) above) filed by the Company with the SEC since
December 31, 1992 (collectively, the "SEC Reports").  The SEC Reports were
prepared in accordance with all applicable requirements of the Securities
Act of 1933, as amended (the "Securities Act"), and the Exchange Act.  As
of their respective dates, none of the SEC Reports, including, without
limitation, any financial statements or schedules included therein,
contained any untrue statement of a material fact or omitted to state a
material fact required to be stated therein or necessary in order to make
the statements therein, in light of the circumstances under which they were
made, not misleading.  The audited consolidated financial statements and
unaudited consolidated interim financial statements of the Company included
in the SEC Reports fairly present, in conformity with generally accepted
accounting principles applied on a consistent basis (except as may be
indicated in the notes thereto), the consolidated financial position of the
Company and its consolidated subsidiaries as of the dates thereof and their
consolidated results of operations and cash flows for the periods then
ended (subject to normal year-end adjustments and the lack of footnote
disclosure (to the extent permitted by SEC rules) in the case of any
unaudited interim financial statements and subject to any subsequent
reclassification as indicated in SEC Reports filed prior to the date
hereof).  The Company has heretofore provided or made available complete
and correct copies of each of the SEC Reports to Parent.

          (b)  Except as disclosed in the SEC Reports filed prior to the
date of this Agreement or as set forth in Schedule 3.5(b), the Company and
its subsidiaries have no liabilities of any nature (whether accrued,
absolute, contingent or otherwise), except for liabilities incurred in the
<PAGE>                                                                14
ordinary course of business since December 31, 1994 or liabilities which
would not, individually or in the aggregate, have a Material Adverse
Effect.  

          Section 3.6  ABSENCE OF CERTAIN CHANGES; NET CASH POSITION;
DERIVATIVES.  (a) Since December 31, 1994, except as disclosed in the SEC
Reports filed prior to the date of this Agreement or as set forth in
Schedule 3.6(a), neither the Company nor any of its subsidiaries has (i)
declared, set aside or paid any dividend or other distribution (whether in

capital stock (other than cash dividends declared and paid on the Series A
Preferred Shares in accordance with their terms and on the Shares to
holders of record on March 31, 1995 in the amount of $0.25 per Share), (ii)
entered into, adopted or amended or materially increased the benefits paid
or payable under any severance, termination or deferred compensation
agreement or arrangement with any director, officer or employee, (iii)
changed any of the accounting principles or practices used by the Company,
except as required as a result of a change in law, SEC guidelines or
generally accepted accounting principles, (iv) settled litigations for
amounts in excess of $3 million in the aggregate, or (v) except as
previously disclosed to Parent, entered into any transaction, or conducted
its business or operations, except in the ordinary course of business
consistent with past practice or where such transactions or conduct would
not, individually or in the aggregate, have a Material Adverse Effect. 
Since December 31, 1994, there has not been any material adverse change in
the business, results of operations (on an annualized basis) or financial
condition of the Company and its subsidiaries, taken as a whole.  For
purposes of this Section 3.6(a), "material adverse change" shall be
construed without reference to the definition of Material Adverse Effect
and shall not mean or include any of the events set forth in Schedule
3.1(a) or any of the transactions effected pursuant to this Agreement.

               (b)  As of the date of this Agreement, subject to the last
sentence of this Section 3.6(b), the Net Cash of the Company and its
subsidiaries is at least $250 million.  As used herein, "Net Cash" means
the excess of (i) the sum of the cash, cash equivalents, short term
investments, notes receivable (excluding trade notes receivable) and long
term readily marketable financial assets of the Company and its
subsidiaries over (ii) the sum of the accounts payable to DCC and its
affiliates (other than the Company and its subsidiaries), dividends
payable, notes payable (excluding trade notes payable), long term debt
(including current portion of long term debt) and any other balance sheet
liabilities for borrowed money of the Company and its subsidiaries, in each
case determined in conformity with generally accepted accounting
principles.  The accounts payable to DCC and its affiliates (other than the
Company and its subsidiaries) included in the $250 million Net Cash
referred to above total $58 million and are as of March 31, 1995.

               (c)  Schedule 3.6(c) sets forth a complete and correct list
of all Derivative Financial Instruments (including the face, contract or
notional amount of and any open position relating to such Derivative
Financial Instruments and a brief summary of the nature and terms thereof)
as of April 30, 1995 to which the Company or any of its subsidiaries is a
party or by which the Company or any of its subsidiaries or any of their
respective assets or properties is subject or bound (including, without
limitation, funds of the Company or any of its subsidiaries invested by any
other person).  For purposes of this Agreement, "Derivative Financial
Instrument" means any futures, forward, swap, option or swaption contract,
or any other financial instrument with similar characteristics and/or
<PAGE>                                                                15
generally characterized by the financial community as a "derivative"
security.

          Section 3.7  PROXY STATEMENT; SCHEDULE 13E-3.  The proxy or
information statement or similar materials distributed to the Company's
stockholders in connection with the Merger, including any amendments or
supplements thereto (the "Proxy Statement"), shall not, at the time filed
with the SEC, at the time mailed to the Company's stockholders, at the time
of the Stockholders' Meeting or at the Effective Time, contain any untrue
statement of a material fact or omit to state any material fact required to
be stated therein or necessary in order to make the statements therein, in
light of the circumstances under which they are made, not misleading. 
Notwithstanding the foregoing, the Company makes no representation or
warranty with respect to any information provided by Parent or Acquisition
specifically for use in the Proxy Statement.  The Proxy Statement will
comply as to form in all material respects with the provisions of the
Exchange Act and the rules and regulations thereunder.  None of the
information provided by the Company specifically for use in any Rule 13e-3
Transaction Statement on Schedule 13E-3 required to be filed with the SEC
under the Exchange Act in connection with the Merger (the "Schedule 13E-3")
will at the time the Schedule 13E-3 or any amendments thereto are filed
with the SEC, contain any untrue statement of a material fact or omit to
state any material fact required to be stated therein or necessary in order
to make the statements therein, in light of the circumstances under which
they are made, not misleading.

          Section 3.8  FINDER'S FEE.  No broker, finder, investment banker
or other intermediary (other than Lehman Brothers) is entitled to any
brokerage, finder's or other fee or commission in connection with the
transactions contemplated by this Agreement or by the Stock Purchase
Agreement based upon arrangements made by and on behalf of the Company. 
The Company has heretofore furnished to Parent a complete and correct copy
of all agreements between the Company and Lehman Brothers pursuant to which
Lehman Brothers would be entitled to any payment relating to the
transactions contemplated hereby or by the Stock Purchase Agreement.

          Section 3.9  ABSENCE OF LITIGATION.  Except as disclosed in the
SEC Reports filed prior to the date hereof, as of the date hereof, there is
no action, suit, claim, investigation or proceeding pending against, or to
the knowledge of the Company, threatened against, the Company or any of its
subsidiaries or any of their respective properties before any court or
arbitrator or any administrative, regulatory or governmental body, or any
agency or official which, individually or in the aggregate, would
reasonably be expected to have a Material Adverse Effect.  Except as

in Schedule 3.9, as of the date hereof, there is no action, suit, claim,
investigation or proceeding pending against, or to the knowledge of the
Company, threatened against, the Company or any of its subsidiaries or any

which (i) challenges or seeks to prevent, enjoin, alter or delay the Merger
or any of the other transactions contemplated hereby or by the Stock
Purchase Agreement; or (ii) alleges criminal action or inaction.  Without
limiting the generality of the foregoing, as of the date hereof, there is
no action, suit, claim, investigation or proceeding relating to debarment
or potential debarment pending against, or to the knowledge of the Company,
threatened against, the Company or any of its subsidiaries before the
Health Care Financing Administration, the Department of Defense, the

similar state agency which, individually or in the aggregate, would
reasonably be expected to have a Material Adverse Effect.  Except as
disclosed in the SEC Reports filed prior to the date of this Agreement, as
of the date hereof, neither the Company nor any of its subsidiaries nor any
of their respective properties is subject to any order, writ, judgment,
injunction, decree, determination or award having, or which would
reasonably be expected to have, a Material Adverse Effect or which would
prevent or delay the consummation of the transactions contemplated hereby. 

          Section 3.10  TAXES.  Except as set forth in the SEC Reports
filed prior to the date of this Agreement or in Schedule 3.10(a), (a) the
Company and its subsidiaries have filed, been included in or sent, all
material returns, material declarations and reports and information returns

relating to any Taxes (as defined below) with respect to any material

are attributable to the portion of any such period ending at the Effective
Time; (e) the charges, accruals and reserves for taxes reflected on the
books of the Company and its subsidiaries are adequate under generally
accepted accounting principles to cover the Tax liabilities accruing or
payable by the Company and its subsidiaries in respect of periods prior to
the date hereof; (f) neither the Company nor any of its subsidiaries is
delinquent in the payment of any material Taxes or has requested any

(g) no material deficiency for any Taxes has been proposed, asserted or

          Section 3.11  EMPLOYEE BENEFITS.  (a) Schedule 3.11(a) contains a
true and complete list of each bonus, deferred compensation, incentive
compensation, stock purchase, stock option, severance or termination pay,
hospitalization or other medical, dental, life, disability or other
insurance, supplemental unemployment benefits, profit-sharing, pension,
savings or retirement plan, program, agreement or arrangement, and each
other employee benefit plan, program, agreement or arrangement, sponsored,
maintained or contributed to or required to be contributed to by the
Company or by any trade or business, whether or not incorporated (an "ERISA
Affiliate"), that together with the Company would be deemed a "single
employer" within the meaning of section 4001 of the Employee Retirement
Income Security Act of 1974, as amended ("ERISA"), for the benefit of any
employee or terminated employee of the Company or any ERISA Affiliate (the
"Plans").  Schedule 3.11(a) identifies each of the Plans that is an
"employee benefit plan," as that term is defined in section 3(3) of ERISA
(the "ERISA Plans").  

               (b)  With respect to each Plan, the Company has heretofore
delivered or made available to Parent true and complete copies of each of
the following documents (to the extent applicable):

                    (i)  a copy thereof;

                    (ii)   a copy of the most recent annual report and
actuarial report, if required under ERISA, and the most recent report
prepared with respect thereto in accordance with Statement of Financial
Accounting Standards No. 87, Employer's Accounting for Pensions;

                    (iii)  a copy of the most recent actuarial report
prepared with respect thereto in accordance with Statement of Financial
Accounting Standards No. 106, Employer's Accounting for Non-Pension
Postretirement Benefits;

                    (iv)   a copy of the most recent Summary Plan
Description;

                    (v)    if the Plan is funded through a trust or any
third party funding vehicle, a copy of the trust or other funding agreement
and the latest financial statements thereof; and

                    (vi)   the most recent determination letter received
from the Internal Revenue Service with respect to each Plan intended to
qualify under section 401(a) of the Internal Revenue Code of 1986, as
amended (the "Code").


<PAGE>                                                                18
               (c)  With respect to each ERISA Plan subject to Title IV of
ERISA, no material liability (other than liabilities for premiums due the
Pension Benefit Guaranty Corporation ("PBGC") (which premiums have been
paid when due)) under Title IV of ERISA has been incurred by the Company or
any ERISA Affiliate that has not been satisfied in full, and, to the
knowledge of the Company, no condition exists that presents a material risk
to the Company or any ERISA Affiliate of incurring a material liability
under such Title.  To the extent this representation applies to sections
4064, 4069 or 4204 of Title IV of ERISA, it is made not only with respect
to each ERISA Plan but also with respect to any employee benefit plan,
program, agreement or arrangement subject to Title IV of ERISA to which the
Company or any ERISA Affiliate made, or was required to make, contributions
during the five (5)-year period ending on the Effective Time.

               (d)  The PBGC has not instituted proceedings to terminate
any ERISA Plan and, to the knowledge of the Company, no condition exists
that presents a material risk that such proceedings will be instituted.

               (e)  Except as set forth on Schedule 3.11(e), with respect
to each ERISA Plan subject to Title IV of ERISA, the present value of
accrued benefits under such plan, based upon the actuarial assumptions used
for funding purposes in the most recent actuarial report prepared by such
plan's actuary with respect to such plan did not exceed, as of its latest
valuation date, the then current value of the assets of such plan allocable
to such accrued benefits.

               (f)  Neither the Company nor any ERISA Affiliate, nor, to
the knowledge of the Company, any ERISA Plan, nor any trust created
thereunder, nor any trustee or administrator thereof has engaged in a
transaction in connection with which the Company or any ERISA Affiliate,
any ERISA Plan, any such trust, or any trustee or administrator thereof, or
any party dealing with any ERISA Plan or any such trust could be subject to
either a civil penalty assessed pursuant to section 409 or 502(i) of ERISA
or a Tax imposed pursuant to section 4975 or 4976 of the Code, except for
such penalties and Taxes which would not, individually or in the aggregate,
have a Material Adverse Effect.

               (g)  No ERISA Plan or any trust established thereunder has
incurred any "accumulated funding deficiency" (as defined in section 302 of
ERISA and section 412 of the Code), whether or not waived, as of the last
day of the most recent fiscal year of such ERISA Plan ended prior to the
Effective Time; and all contributions required to be made with respect
thereto (whether pursuant to the terms of any ERISA Plan or otherwise) on
or prior to the Effective Time have been timely made.

               (h)  No ERISA Plan is a "multiemployer pension plan," as
defined in section 3(37) of ERISA, nor is any ERISA Plan a plan described
in section 4063(a) of ERISA.

               (i)  To the knowledge of the Company, each Plan has been
operated and administered in all material respects in accordance with its
terms and applicable law, including but not limited to ERISA and the Code.

               (j)  Each ERISA Plan intended to be "qualified" within the
meaning of section 401(a) of the Code has been drafted with the intention
to be so qualified and has been submitted to the Internal Revenue Service
along with a request for a favorable determination letter on or before the
date hereof, and it is anticipated that each such plan will be modified so
as to incorporate any conforming amendments requested or required by the
<PAGE>                                                                19
Internal Revenue Service as a condition to the issuance of such favorable

          Section 3.15  SIGNIFICANT AGREEMENTS.  Schedule 3.15 sets forth a
complete and correct list of all contracts, agreements and commitments
(oral or written) between the Company or any of its subsidiaries, on the
one hand, and on the other hand, (i) DCC or any of its affiliates (other
than the Company and its subsidiaries) (excluding contracts, agreements and
commitments which collectively are immaterial to the Company and except for
this Agreement and certain other agreements entered into in connection with
this Agreement and to which Parent is a party or of which Parent is aware);
(ii) Chugai Pharmaceutical Co., Ltd. or any of its affiliates; or (iii)
Tanabe Seiyaku Co., Ltd. or any of its affiliates (the contracts,
agreements and commitments listed in Schedule 3.15, collectively, the
"Significant Agreements").  The Company has heretofore furnished or made
available to Parent complete and correct copies of the Significant
Agreements, each as amended or modified to the date hereof (including any
waivers with respect thereto).  Except as set forth on Schedule 3.4 or
Schedule 3.15, each of the Significant Agreements is in full force and
effect and enforceable in accordance with its terms; neither the Company
nor any of its subsidiaries has received any notice (written or oral) of
cancellation or termination of, or any expression or indication of an
intention or desire to cancel or terminate, any of the Significant
Agreements; no Significant Agreement is the subject of, or, to the
knowledge of the Company, has been threatened to be made the subject of,
any arbitration, suit or other legal proceeding; with respect to any
Significant Agreement which by its terms will terminate as of a certain
date unless renewed or unless an option to extend such Significant
Agreement is exercised, neither the Company nor any of its subsidiaries has
received any notice (written or oral), or otherwise has any knowledge, that
any such Significant Agreement will not be so renewed or that any such
extension option will not be exercised; and there exists no event of
default or occurrence, condition or act on the part of the Company or any
of its subsidiaries or, to the knowledge of the Company, on the part of the
other parties to the Significant Agreements which constitutes or would
constitute (with notice or lapse of time or both) a breach of or default
under any of the Significant Agreements, except to the extent that the
inaccuracy of the foregoing insofar as it relates to contracts, agreements

<PAGE>                                                                23
and commitments referenced in Section 3.15(i) would not, individually or in
the aggregate, have a Material Adverse Effect. 

          Section 3.16  INSURANCE.  Schedule 3.16 sets forth a complete and
correct list of all material insurance policies (including a brief summary
of the nature and terms thereof and any amounts paid or payable to the
Company or any of its subsidiaries thereunder) providing coverage in favor
of the Company or any of its subsidiaries or any of their respective
properties.  Each such policy is in full force and effect, no notice of
termination, cancellation or reservation of rights has been received with
respect to any such policy, there is no default with respect to any
provision contained in any such policy, and there has not been any failure
to give any notice or present any claim under any such policy in a timely
fashion or in the manner or detail required by any such policy, except for
any such failures to be in full force and effect, any such terminations,
cancellations, reservations or defaults, or any such failures to give
notice or present claims which, individually or in the aggregate, would not
reasonably be expected to have a Material Adverse Effect.  The coverage
provided by such policies is, in the Company's judgment, reasonable in
scope and amount, in light of the risks attendant to the business and
activities of the Company and its subsidiaries.  

          Section 3.17  LABOR MATTERS.  Except as set forth in Schedule
3.17 and except for normal and customary labor arrangements outside North

proceedings of any labor union to organize any of their respective
employees.  There is no labor dispute, strike or work stoppage against the
Company or any of its subsidiaries pending or, to the Company's knowledge,
threatened which may interfere with the respective business activities of
the Company or any of its subsidiaries, except where such dispute, strike
or work stoppage would not reasonably be expected to have a Material
Adverse Effect.

conditions of each License in each country in which such Product is
marketed, and with all requirements pertaining to the
manufacture,distribution, sale or human research of such Product which is
not required to be the subject of a License; (C) the Company and its
<PAGE>                                                                24
subsidiaries are in full compliance with all applicable requirements (as
set forth in relevant statutes and regulations) regarding registration,
licensure or notification for each site (in any country) at which such
Product is manufactured, processed, packed, held for distribution or from
which it is distributed; and (D) to the extent such product is intended for
export from the United States, the Company and its subsidiaries are in full
compliance with either all United States Food and Drug Administration
(hereafter, "FDA") requirements for marketing or 21 U.S.C. 381(e) or 382;

subsidiaries have been and are being conducted in full compliance with the

good manufacturing practice regulations issued by FDA and counterpart

nonclinical laboratory studies, as described in 21 C.F.R. 58.3(d),

Union and other countries; and (iv) the Company and its subsidiaries are in
full compliance with all reporting requirements for all Licenses or plant
registrations described in the preceding clauses (b)(i)(A) and (b)(i)(C),
including, but not limited to, the adverse event reporting requirements for
drugs in 21 C.F.R. Parts 312 and 314 and for devices in 21 C.F.R. Parts 812
and 803; except, in the case of the preceding clauses (b)(i)(A) through
(b)(i)(D), inclusive, (b)(ii), (b)(iii) and (b)(iv), for any such failures
to obtain or noncompliances which, individually or in the aggregate, would
not reasonably be expected to have a Material Adverse Effect.  Without

definition shall specifically include, with respect to the United States,
new drug applications, abbreviated new drug applications, product license
applications, investigational new drug applications, premarket approval
applications, premarket notifications under Section 510(k) of the Federal

Company nor any of its subsidiaries nor any of their officers, employees or
agents has made any untrue statement of a material fact or fraudulent
statement to FDA, failed to disclose a fact required to be disclosed to
FDA, or committed any act, made any statement, or failed to make any
statement, that would reasonably be expected to provide a basis for FDA to
invoke its policy respecting "Fraud, Untrue Statements of Material Facts,
Bribery, and Illegal Gratuities," set forth in 56 Fed. Reg. 46191
(September 10, 1991).

               (d)  The Company has provided or made available to Parent
all documents in its possession concerning communications to or from FDA,
or prepared by FDA, which bear in any material respect on compliance by the
Company and its subsidiaries with FDA regulatory requirements.

               (a)  Promptly following the purchase by Acquisition, Parent
or their affiliates of the Dow Shares and from time to time thereafter,
Acquisition shall be entitled to designate up to such number of directors,
rounded up to the next whole number, on the Board that equals the product
of (i) the total number of directors on the Board (giving effect to the
election of any additional directors pursuant to this Section) and (ii) the
percentage that the number of Shares owned by Acquisition and its
affiliates (including any Shares purchased pursuant to the Stock Purchase
Agreement) bears to the total number of outstanding Shares, and the Company
shall, upon request by Acquisition, promptly either increase the size of
the Board or use its reasonable best efforts to secure the resignation of
such number of directors as is necessary to enable Acquisition's designees
to be elected to the Board and shall cause Acquisition's designees to be so
elected.  Promptly upon request by Acquisition, the Company will use its
reasonable best efforts to cause persons designated by Acquisition to
constitute the same percentage as is on the Board of (i) each committee of
the Board, (ii) each board of directors of each subsidiary of the Company
designated by Acquisition and (iii) each committee of each such board. 
Simultaneously with the purchase by Acquisition, Parent or their affiliates
of the Dow Shares, DCC shall use its reasonable best efforts to cause each
<PAGE>                                                                31
employee of DCC who is on the Board to resign from the Board and from the
board of directors of any subsidiary of the Company on which such
individual serves.  Subject to the foregoing, the Company shall use its
reasonable best efforts to ensure that all of the members of the Board as

Board until the Effective Time.

               (b)  The Company's obligations to appoint designees to the
Board shall be subject to Section 14(f) of the Exchange Act, and Rule 14f-1
promulgated thereunder.  As promptly as practicable following the date of
this Agreement, the Company shall take all actions required pursuant to
Section 14(f) and Rule 14f-1 in order to fulfill its obligations under this
Section 6.2 and shall file with the SEC and distribute to its stockholders
such information as is required under Section 14(f) and Rule 14f-1.  Parent
or Acquisition will supply to the Company in writing and be solely

By-Laws of the Company, any termination of this Agreement by the Company,
any extension by the Company of the time for the performance of any of the
obligations or other acts of Parent or Acquisition or any waiver of any of
the Company's rights hereunder, will require the concurrence of a majority
of the directors of the Company then in office who are not designees of
Acquisition or employees of DCC or the Company.  From and after the
purchase of the Dow Shares by Acquisition, Parent or their affiliates and
prior to the Effective Time, Parent and Acquisition will cooperate with the
Company to ensure that the Board at all times includes at least two
directors who are not designees of Acquisition or employees of DCC or the
Company.

          Section 6.3  PROXY STATEMENT; SCHEDULE 13E-3. 
 
               (a)  The Company shall, as promptly as practicable following
the date hereof, prepare and file the Proxy Statement with the SEC under
the Exchange Act.  As soon as practicable following completion of review of
the Proxy Statement by the SEC, the Company shall mail the Proxy Statement
to its stockholders who are entitled to vote at the Stockholders' Meeting. 
Subject to the fiduciary obligations of the Board under applicable law, the
Proxy Statement shall contain the recommendation of the Board that the
stockholders of the Company adopt this Agreement and the Merger.

               (b)  In the event Parent and the Company determine that the
Schedule 13E-3 is required to be filed with the SEC in connection with the
Merger, then, as promptly as practicable following notice of such
determination, the Company, Parent and Acquisition shall prepare and file
the Schedule 13E-3 with the SEC.  

               (c)  The Company, Parent and Acquisition shall cooperate
with one another in the preparation and filing of the Proxy Statement and
the Schedule 13E-3 (if required to be filed) and shall use their reasonable
best efforts to promptly obtain and furnish the information required to be
included in the Proxy Statement and the Schedule 13E-3 and to respond
promptly to any comments or requests made by the SEC with respect to the
Proxy Statement or the Schedule 13E-3 (if required to be filed).  Each
party hereto shall promptly notify the other parties of the receipt of
<PAGE>                                                                32
comments of, or any requests by, the SEC with respect to the Proxy
Statement or the Schedule 13E-3 (if required to be filed), and shall
promptly supply the other parties with copies of all correspondence between
such party (or its representatives) and the SEC (or its staff) relating
thereto.  The Company, Parent and Acquisition each agrees to correct any
information provided by it for use in the Proxy Statement or the Schedule

misleading.     

          Section 6.4  ACCESS TO INFORMATION.  (a) Subject to applicable

offices, warehouses and other facilities and to all books and records of
the Company and its subsidiaries, will permit each of Parent and
Acquisition and their respective counsel, financial advisors, auditors and
other authorized representatives to make such inspections as Parent or
Acquisition may reasonably require and will cause the Company's officers
and those of its subsidiaries to furnish Parent or Acquisition or their
representatives with such financial and operating data and other
information with respect to the business and properties of the Company and
any of its subsidiaries as Parent or Acquisition may from time to time
reasonably request.  No investigation pursuant to this Section 6.4 shall
affect any representations or warranties of the parties herein or the
conditions to the obligations of the parties hereunder.  The foregoing
shall not require the Company to permit any inspection, or to disclose any
information, which in the reasonable judgment of the Company would result
in the disclosure of any trade secrets of third parties or violate any
obligation of the Company with respect to confidentiality if the Company
shall have used reasonable efforts to obtain the consent of such third
party to such inspection or disclosure.

               (b)  Each of Parent and Acquisition agrees to be bound by
the confidentiality agreement, dated as of August 18, 1994 (the
"Confidentiality Agreement"), among Hoechst AG ("HAG"), Hoechst Celanese
Corporation ("HCC"), Roussel Uclaf S.A. ("RU"), DCC and the Company as if
the references to HAG, HCC and RU therein were to Parent and Acquisition,
except that Parent and Acquisition may (i) enter into this Agreement and
the Stock Purchase Agreement and (ii) acquire Shares pursuant to the Merger
and the Stock Purchase Agreement.

          Section 6.5  REASONABLE BEST EFFORTS.  Subject to the terms and
conditions herein provided, each of the parties hereto agrees to use its
reasonable best efforts to take, or cause to be taken, all actions, and to
do, or cause to be done, all things reasonably necessary, proper or
advisable under applicable laws and regulations to consummate and make
effective the transactions contemplated by this Agreement and the Stock
Purchase Agreement.  Without limiting the generality of the foregoing,
Parent, Acquisition, DCC and the Company shall cooperate with one another
(i) in the preparation and filing of any required filings under the HSR Act
and the other laws referred to in Sections 3.4(b), 4.3(b) and 5.3(b); (ii)
in determining whether action by or in respect of, or filing with, any
governmental body, agency, official or authority (either domestic or
foreign) is required, proper or advisable or any actions, consents, waivers
or approvals are required to be obtained from parties to any contracts, in
connection with the transactions contemplated by this Agreement and the
Stock Purchase Agreement; and (iii) in seeking timely to obtain any such
actions, consents and waivers and to make any such filings.  In case at any
<PAGE>                                                                33
time after the Effective Time any further action is necessary or desirable
to carry out the purposes of this Agreement, the proper officers and
directors of each party hereto shall take all such necessary action.

          Section 6.6  PUBLIC ANNOUNCEMENTS.  Parent and Acquisition, on
the one hand, and DCC and the Company, on the other hand, will consult with
each other before issuing any press release with respect to the

consultation, except as may be required by applicable law or by applicable
rules of any securities exchange.

          Section 6.7  INDEMNIFICATION; INSURANCE.

their affiliates of the Dow Shares, Parent and Acquisition shall indemnify

date hereof or who becomes prior to the Effective Time, an officer,
director or employee of the Company or any of its subsidiaries
(collectively, the "Indemnified Parties" and individually, the "Indemnified
Party") against all losses, liabilities, expenses, claims or damages in
connection with any claim, suit, action, proceeding or investigation based
in whole or in part on the fact that such Indemnified Party is or was a
director, officer or employee of the Company or any of its subsidiaries and
arising out of acts or omissions occurring prior to and including the
Effective Time (including but not limited to the transactions contemplated
by this Agreement) to the fullest extent permitted by Delaware Law, for a
period of not less than six years following the Effective Time; PROVIDED
that in the event any claim or claims are asserted or made within such six-
year period, all rights to indemnification in respect of any such claim or
claims shall continue until final disposition of any and all such claims.

               (b)  Parent shall cause the Certificate of Incorporation and
By-Laws of the Surviving Corporation and its subsidiaries to include
provisions for the limitation of liability of directors and indemnification
of the Indemnified Parties to the fullest extent permitted under applicable
law and shall not permit the amendment of such provisions in any manner
adverse to the Indemnified Parties, as the case may be, without the prior
written consent of such persons, for a period of six years from and after
the date hereof.

action, proceeding or investigation in connection with any matter,
including, without limitation, the transactions contemplated by this

(including the cost of any investigation and preparation) incurred in
connection therewith.  Parent shall pay all expenses, including attorneys'
fees, that may be incurred by any Indemnified Party in enforcing the
indemnity and other obligations provided for in this Section 6.7 or any
action involving an Indemnified Party resulting from the transactions
contemplated by this Agreement.

               (d)  For six years after the Effective Time, the Surviving
Corporation shall cause to be maintained the current policies of directors'
and officers' liability insurance maintained by the Company (provided that
the Surviving Corporation may substitute therefor policies of at least the
same coverage containing terms and conditions which are substantially
<PAGE>                                                                34
equivalent) with respect to matters occurring prior to the Effective Time,
to the extent such policies are available; PROVIDED, that in no event shall
the Surviving Corporation be required to expend, in order to maintain or
procure insurance coverage pursuant to this Section 6.7(c), any amount per
annum greater than 125% of the current annual premiums paid by the Company
for such insurance (which the Company represents and warrants to be not
more than $620,000).

               (e)  Any determination to be made as to whether any
Indemnified Party has met any standard of conduct imposed by law shall be
made by legal counsel reasonably acceptable to such Indemnified Party,
Parent and the Surviving Corporation, retained at Parent's and the

give prompt notice to Parent or Acquisition, and Parent or Acquisition
shall give prompt notice to the Company, upon becoming aware of (i) the
occurrence, or non-occurrence, of any event the occurrence, or non-

this Agreement to be untrue or inaccurate and (ii) any failure of the
Company, Parent or Acquisition, as the case may be, to comply with or
satisfy any covenant, condition or agreement to be complied with or
satisfied by it hereunder; PROVIDED, that the delivery of any notice
pursuant to this Section 6.8 shall not limit or otherwise affect the
remedies available hereunder to the party receiving such notice.

          Section 6.9  REDEMPTION OF SERIES A PREFERRED STOCK; TERMINATION
OF STOCK PLANS.  (a) Effective immediately prior to the Merger, the Company
shall redeem for cash all of the outstanding Series A Preferred Shares at

proposals that constitute, or would lead to, a proposal or offer for a
merger, consolidation, business combination, sale of substantial assets,
sale of a substantial percentage of shares of capital stock (including,

applicable law, engage in negotiations or discussions concerning, or
provide any non-public information to any person or entity relating to, any

consultation with outside legal counsel that such action is necessary for
the Board to comply with its fiduciary duties to stockholders under
applicable law and prior to furnishing such information to, or entering
into discussions or negotiations with, such person, the Board receives from
such person an executed confidentiality agreement with terms no less
favorable to the Company than those contained in the Confidentiality
Agreement; or (B) comply with Rules 14d-9 and 14e-2 promulgated under the
Exchange Act with regard to an Acquisition Proposal.

               (b)  The Company shall notify Parent immediately (and no
later than 24 hours) after receipt by the Company of any Acquisition
Proposal or any request for non-public information in connection with an
Acquisition Proposal or for access to the properties, books or records of

existing as of the date of this Agreement between the Company or any of its
subsidiaries, on the one hand, and DCC or any of its affiliates (other than

name change to a new name that does not contain DOW or a name confusingly
similar to DOW.  Within eighteen (18) months following the purchase of the

proceeding is premised on the use of the name and trademark DOW by the
Company or any of its subsidiaries or on their products.  The Company's
indemnification under this Section 6.16(b) shall be limited solely to the
out-of-pocket costs and expenses (including reasonable fees and expenses of

obtaining dismissal or other favorable disposition of any such suits,
claims or proceedings but shall not include the amounts of any settlement

shall be deemed to amend, waive or supersede any other provision of the
1989 Stock Acquisition Agreement, including, without limitation, Section

COMPANIES ANNOUNCE DEFINITIVE AGREEMENTS FOR HOECHST TO ACQUIRE MARION
MERRELL DOW

     FRANKFURT, Germany; KANSAS CITY, Mo.; and MIDLAND, Mi., May 4, 1995--
Hoechst AG, Marion Merrell Dow Inc. and The Dow Chemical Company today
announced the signing of definitive agreements for Hoechst to acquire all
of the outstanding shares of Marion Merrell Dow, pending regulatory
approvals, for a basic price of U.S. $25.75 per share in cash.  Upon
completion, the acquisition will expand Hoechst's global pharmaceutical
business to annual sales of approximately U.S. $10 billion, ranking among
the world's largest.

The acquisition is planned in two stages:

     Hoechst Corporation, a U.S. subsidiary of Hoechst AG, and Dow Chemical
     signed an agreement for Hoechst to purchase from Dow approximately 197
     million shares of Marion Merrell Dow at a price of U.S. $25.75 per
     share, or about U.S. $5.1 billion.  Dow's interest amounts to 71
     percent of the 277 million shares outstanding.

     Marion Merrell Dow shareholders will vote on a proposal to merge the
     company with Hoechst Corporation, which will result in Marion Merrell
     Dow becoming a wholly owned subsidiary of Hoechst.  As a result of the
     merger, minority shareholders (who currently own approximately 80
     million shares or 29 percent of the stock) will receive merger
     consideration of U.S. $25.75 per share in cash, plus an additional pro
     rata dividend that depends on the timing of the closing of the merger.

GLOBAL PHARMA BUSINESS TO BE KNOWN AS HOECHST MARION ROUSSEL

Following completion of the acquisition, Hoechst will conduct its global
pharmaceutical business under the name Hoechst Marion Roussel.

The senior leadership of the new company will include Jean-Pierre Godard,
currently head of Hoechst's pharmaceutical division, who will serve as the
head of pharmaceuticals for Hoechst Marion Roussel, and Richard J. Markham,
currently president and chief operating officer of Marion Merrell Dow, who
will assume the position of deputy head of pharmaceuticals.

Hoechst Marion Roussel will be organized into four geographic regions to
meet customer needs in North America, Europe/Africa, Asia and Latin
America.  The North American business unit will be headquartered in Kansas
City, Mo.

NO CAPITAL INCREASE AT HOECHST AG FOR THE LARGEST ACQUISITION

Hoechst's acquisition of Marion will cost a total of approximately U.S.
$7.1 billion, the largest U.S. acquisition to date by a German company.

The purchase is being financed partly by means of a U.S. $2.5 billion
capital increase at Hoechst Corporation.  No capital increase at Hoechst AG
is required for this purpose.  This amount is covered by liquid assets
available within Hoechst.  The remaining sum, approximately U.S. $4.6
billion, will be financed by Hoechst Corporation through external loans.

The Hoechst companies are an international network of innovative and
customer-oriented companies.  Global sales totaled DM 49.6 billion (U.S.
<PAGE>                                                                46
$30.6 billion) in 1994, and Hoechst companies ranked among the leading
suppliers in the pharmaceutical, agricultural and industrial chemical
sectors of Europe, the Americas and Asia.

The current pharmaceutical division, Hoechst Roussel Pharma, comprises the
pharmaceutical businesses of Hoechst AG and Roussel Uclaf S.A., in which
Hoechst owns a 56 percent share.  Hoechst's pharmaceutical sales last year
amounted to DM 10.3 billion (U.S. $6.3 billion), with about 60 percent of
those sales in Europe, employing about 33,500 associates worldwide.

The largest-selling products of Hoechst Roussel Pharma are in therapeutic
fields  such as infections, vascular and cardiovascular diseases, and
diabetes.  Hoechst invested more than DM 1.7 billion (U.S. $1.1 billion)
last year on research and development of new drugs.

GLOBAL EXPANSION OF PHARMACEUTICALS HAS GREATEST STRATEGIC IMPORTANCE

Hoechst has embarked on a structural and strategic reorientation to
concentrate on core activities and further strengthen its businesses in the
pharmaceutical, agricultural and industrial chemical sectors.  The most
important role will be played by the pharmaceutical division, which Hoechst
intends to expand worldwide--including innovative single-source drugs,
diagnostics, plasma products and generics.

With the planned acquisition of Marion Merrell Dow, Hoechst particularly
seeks to strengthen its position in North America.  The United States is
not only the largest area for pharmaceutical sales--the U.S. also is where
the world's standards are set for drug approval and for pharmaceutical
manufacturing.

Jurgen Dormann, CEO and Chairman of the Board of Management of Hoechst AG,
said:  "We need a partner with a strong North American sales network,
contacts with the regulatory authorities, access to the innovative field of
biotechnology research in the United States, a complementary product line
and a strong clinical research effort.  As the health care market grows
tougher and more competitive, we also want to join with a company that is a
respected ally of U.S. managed health care organizations.  Marion is the
best candidate to help us achieve these strategic goals."

MARION: ONE OF THE MOST RESPECTED SUPPLIERS OF HEALTH CARE ORGANIZATIONS

Marion is one of the 15 largest pharmaceutical companies in the United
States and one of the most respected suppliers of the large health care
organizations in the country.  With approximately 9,000 associates,
including over 1,000 in its U.S. field sales force, Marion last year
achieved sales of U.S. $3.1 billion and a net profit of U.S. $438 million. 
North American sales were 66 percent of Marion's 1994 sales, Europe was 17
percent and the Pacific Region was 17 percent.

Marion's activities are focused on the therapeutic fields of cardiovascular
diseases, allergies and respiratory disease, gastrointestinal, and diseases
of the central nervous system.  Expenditure on research and development in
1994 amounted to U.S. $462 million.  Marion's activities complement those
of Hoechst and Roussel well.

"Strategically, bringing these companies together will enable us to better
serve health care customers and millions of patients worldwide," said Fred
W. Lyons, Jr., chairman and chief executive officer of Marion Merrell Dow. 
"With a strong commitment to research and development, plus an organization
<PAGE>                                                                47
that is addressing the changing needs of health care, we will have the
critical mass, geographic reach and depth of product line to be a
formidable competitor in the global marketplace."


COMPANIES HAVE COMPLEMENTARY PRODUCT PORTFOLIOS, REGIONAL STRUCTURE

As Dr. Karl-Gerhard Seifert, the member of the Hoechst AG board who is
responsible for pharmaceuticals, emphasized:  "We are convinced that the
product portfolios and regional structures of the companies complement each
other well.  The considerable synergies will result in a successful
partnership between Hoechst-Roussel and Marion."

Dow Chemical has maintained its pharmaceutical activities in Latin America
independent of Marion.  Hoechst and Dow Chemical also agreed today that
Roussel Uclaf will acquire the Latin American pharmaceutical business, with
sales of U.S. $175 million, from Dow.

TRANSITION PROCESS TO BEGIN IMMEDIATELY

The integration of Marion confronts Hoechst and Roussel, and the management
of the pharmaceutical division, with a demanding task.  The aim of this
integration is to establish a joint business with a uniform, globally
responsible management structure that preserves the historic strengths of
the various companies involved.  This integration will be accomplished
through a series of task forces, with representation from Hoechst's
pharmaceutical subsidiaries and Marion Merrell Dow.

The recommendations of the task forces will be reviewed by a steering
committee chaired by Mr. Dormann.  Mr. Lyons will be vice chairman of the
committee.

Announcements on additional management appointments at Hoechst Marion
Roussel, and the recommendations of the various merger transition task
forces, will be made as appropriate following their review by the steering
committee.
