                          AGREEMENT AND PLAN OF MERGER

      AGREEMENT AND PLAN OF MERGER (this "Agreement"), dated as of June 10,
1998, by and among Kluwer Boston, Inc., a Massachusetts corporation ("Parent"),
PPC Acquisition Corp., a Delaware corporation and subsidiary of Parent
("Purchaser"), and Plenum Publishing Corporation (the "Company"), a Delaware
corporation.

      WHEREAS, the respective Boards of Directors of Parent, Purchaser and the
Company deem it advisable and in the best interests of the stockholders of such
corporations to effect the merger of Purchaser and the Company pursuant to this
Agreement;

      WHEREAS, the respective Boards of Directors of Parent, Purchaser and the
Company have approved the acquisition of the Company by Parent and, in
furtherance of such acquisition, Parent proposes to make or to cause Purchaser
to make a cash tender offer (the "Offer") for all of the outstanding shares of
common stock of the Company, par value $.10 per share (the "Shares"), at a price
of $73.50 net to the seller per Share (the "Purchase Price") on the terms set
forth in the Offer Documents (as such term is defined below), and the Board of
Directors of the Company (the "Board") has unanimously approved the Offer and
resolved to recommend that it be accepted by the stockholders of the Company;

      WHEREAS, certain stockholders of the Company and Parent are entering into
Stock Purchase Agreements, dated as of the date hereof ("Stock Purchase
Agreements"), pursuant to which the Company, and such stockholders will, among
other things, agree to sell Shares to Parent under certain circumstances; and

      WHEREAS, the Company and Parent are entering into an Option Agreement,
dated as of the date hereof ("Option Agreement"), pursuant to which the Company
will grant to Parent an option to acquire an additional 19.9% of its Shares at
the Purchase Price.

      NOW, THEREFORE, in consideration of the foregoing and the respective
representations, warranties, covenants and agreements set forth herein, Parent,
Purchaser and the Company agree as follows:

                                    ARTICLE I

                                    THE OFFER

      SECTION 1.1 The Offer.

      (a) Provided that nothing shall have occurred that would result in the
failure of any of the conditions set forth in Annex I hereto, Parent and
Purchaser shall, as promptly as practicable following the date hereof and in any
event not later than five (5) business days after the public announcement of the
execution hereof, commence their Offer to purchase the Shares at a price equal
to the Purchase Price. The Offer shall be made by means of an offer to purchase
(the "Offer to Purchase" and, together with a letter of transmittal relating
thereto, the "Offer Documents") which shall be subject solely to the condition
that there be validly tendered and not withdrawn prior to the expiration of the
Offer that number of Shares


                                       1


which, when added to any Shares acquired pursuant to the Stock Purchase
Agreements simultaneously with the acceptance of Shares pursuant to the Offer,
represents at least a majority of the Shares outstanding on a fully diluted
basis (the "Minimum Condition") and to the other conditions set forth in Annex I
hereto (including the expiration of applicable waiting periods under the HSR Act
(as hereinafter defined)). As soon as practicable, Parent and Purchaser shall
file with the Securities and Exchange Commission (the "SEC") a Schedule 14D-1
(which schedule, together with all amendments and supplements thereto, is
hereinafter referred to as the "Schedule 14D-1") with respect to the Offer. The
Company and its counsel shall be given the opportunity to review the Schedule
14D-1 (as defined below) before it is filed with the SEC. In addition, Parent
and Purchaser agree to provide the Company and its counsel with any comments,
whether written or oral, that Parent and/or its counsel may receive from time to
time from the SEC or its staff with respect to the Schedule 14D-1 promptly after
the receipt of such comments or other communications. Without the prior written
consent of the Company, neither Parent nor Purchaser shall decrease the price
per Share or change the form of consideration payable in the Offer, decrease the
number of Shares sought to be purchased in the Offer, change the conditions set
forth in Annex I, impose additional conditions to the Offer or amend any other
term of the Offer in any manner materially adverse to the holders of the Shares.
Subject to the terms of the Offer and this Agreement and the satisfaction or
waiver of all the conditions of the Offer set forth in Annex I hereto as of any
expiration date of the Offer, Parent and/or Purchaser will accept for payment
and pay for all Shares validly tendered and not properly withdrawn pursuant to
the Offer as soon as practicable after such expiration date of the Offer.
Notwithstanding the foregoing, Purchaser may, without the consent of the
Company, (i) extend the Offer on one or more occasions for up to ten business
days for each such extension beyond the then scheduled expiration date (the
initial scheduled expiration date being 20 business days following commencement
of the Offer), if at the then scheduled expiration date of the Offer any of the
conditions to Purchaser's obligation to accept for payment and pay for the
Shares shall not be satisfied or waived, until such time as such conditions are
satisfied or waived, (ii) increase the Purchase Price and extend the Offer for
any period required by any rule, regulation, interpretation or provision of the
SEC or the staff thereof applicable to the Offer and (iii) extend the Offer for
an aggregate period of not more than 10 business days beyond the latest
expiration date that would otherwise be permitted under clause (i) or (ii) of
this sentence if there shall not have been tendered and not withdrawn pursuant
to the Offer at least 90% of the outstanding Shares.

      (b) The Offer Documents will comply in all material respects with the
provisions of applicable federal securities laws and, on the date filed with the
SEC and on the date first published, sent or given to the Company's
stockholders, shall not 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 made therein, in light of the circumstances under which
they were made, not misleading, except that no representation is made by Parent
or Purchaser with respect to information supplied by the Company in writing for
inclusion in the Offer Documents. Each of Parent and Purchaser, on the one hand,
and the Company, on the other hand, agrees to correct promptly any information
provided by it for use in the Offer Documents if and to the extent that it shall
have become false or misleading in any material respect and Parent and Purchaser
further agree to take all steps necessary to cause the Offer Documents as so
corrected to be filed with the SEC and to be disseminated to stockholders of the
Company, in each case as and to the extent required by applicable federal
securities laws.


                                       2


      SECTION 1.2 Company Action.

      (a) The Company hereby approves of and consents to the Offer and
represents that, at a meeting duly called and held, its Board of Directors has
(i) unanimously determined that this Agreement and the transactions contemplated
hereby and thereby, including, without limitation, the Offer and the Merger, are
fair to and in the best interest of the Company's stockholders, (ii) unanimously
approved this Agreement and the transactions contemplated hereby and thereby,
including, without limitation, the Offer and the Merger and (iii) unanimously
resolved to recommend that the stockholders of the Company accept the Offer,
tender their Shares thereunder to Purchaser and approve and adopt this Agreement
and the Merger; provided, that such recommendation may be withdrawn, modified or
amended if, in the good faith opinion of the Directors, only after receipt of
advice from legal counsel, the failure to withdraw, modify or amend such
recommendation would result in the Board violating its fiduciary duties to the
Company's stockholders under applicable law. The Company consents to the
inclusion of such recommendation and approval in the Offer Documents.

      (b) Contemporaneously with the commencement of the Offer as provided for
in Section 1.1, the Company will file with the SEC a Solicitation/Recommendation
Statement on Schedule 14D-9 (which schedule, together with all amendments and
supplements thereto, is hereafter referred to as the "Schedule 14D-9") which
shall reflect the recommendations and actions of the Company's Board of
Directors referred to above. The Company further agrees to take all steps
necessary to cause the Schedule 14D-9 to be filed with the SEC and to be
disseminated to holders of the Shares, in each case as and to the extent
required by applicable federal securities laws. Each of the Company, on the one
hand, and Parent and Purchaser, on the other hand, agrees to promptly correct
any information provided by it for use in the Schedule 14D-9 if and to the
extent that it shall have become false or misleading in any material respect and
the Company further agrees to take all steps necessary to cause the Schedule
14D-9 as so corrected to be filed with the SEC and to be disseminated to
stockholders of the Company, in each case as and to the extent required by
applicable federal securities laws. Parent and its counsel shall be given the
opportunity to review the Schedule 14D-9 before it is filed with the SEC. In
addition, the Company agrees to provide Parent and its counsel with any
comments, whether written or oral, that the Company and/or its counsel may
receive from time to time from the SEC or its staff with respect to the Schedule
14D-9 promptly after the receipt of such comments or other communications.

      (c) In connection with the Offer, the Company will promptly furnish or
cause to be furnished to Parent and Purchaser mailing labels, security position
listings and any available listing, or computer file containing the names and
addresses of all record holders of the Shares as of a recent date, and shall
furnish Parent and Purchaser with such additional information (including, but
not limited to, updated lists of holders of the Shares and their addresses,
mailing labels and lists of security positions) and assistance as Parent,
Purchaser or their respective agents may reasonably request in communicating the
Offer to the record and beneficial holders of the Shares. Except for such steps
as are necessary to disseminate the Offer Documents, Parent and Purchaser shall
hold in confidence the information contained in any of such labels and lists and
the additional information referred to in the preceding sentence, will use such
information in connection with the Offer, and, if this Agreement is terminated,
will upon request of the Company deliver or cause to be delivered to the Company
all copies of such information then in its possession or the possession of its
agents or representatives.


                                       3


      SECTION 1.3 Directors.

      (a) Promptly upon the purchase of Shares by Parent or Purchaser or any of
its Subsidiaries pursuant to the Offer and/or pursuant to any of the Stock
Purchase Agreements which represents at least a majority of the outstanding
Shares, Purchaser shall be entitled to designate such number of directors,
rounded up to the next whole number, on the Board of Directors of the Company as
is equal to the product of the total number of directors on such Board (giving
effect to the directors designated by Purchaser pursuant to this sentence)
multiplied by the percentage that the number of Shares so accepted for payment
bears to the total number of Shares then outstanding. In furtherance thereof,
the Company shall, upon request of the Purchaser, use its reasonable best
efforts promptly either to increase the size of its Board of Directors or secure
the resignations of such number of its incumbent directors, or both, as is
necessary to enable Purchaser's designees to be so elected to the Company's
Board of Directors, and shall take all actions available to the Company to cause
Purchaser's designees to be so elected. At such time, the Company shall, if
requested by Purchaser, also cause persons designated by Purchaser to constitute
at least the same percentage (rounded up to the next whole number) as is on the
Company's Board of Directors of (i) each committee of the Company's Board of
Directors, (ii) each board of directors (or similar body) of each Subsidiary of
the Company and (iii) each committee (or similar body) of each such board.

      (b) The Company shall promptly take all actions required pursuant to
Section 14(f) of the Exchange Act and Rule 14f-1 promulgated thereunder in order
to fulfill its obligations under Section 1.3(a), including mailing to
stockholders the information required by such Section 14(f) and Rule 14f-1 as is
necessary to enable Purchaser's designees to be elected to the Company's Board
of Directors. Purchaser or Parent will supply the Company and be solely
responsible for any information with respect to either of them and their
nominees, officers, directors and affiliates required by such Section 14(f) and
Rule 14f-1. The provisions of this Section 1.3 are in addition to and shall not
limit any rights which Purchaser, Parent or any of their affiliates may have as
a holder or beneficial owner of Shares as a matter of law with respect to the
election of directors or otherwise.

      (c) In the event Purchaser's designees are elected to the Company's Board
of Directors, until the Effective Time (as defined below), the Company's Board
shall have at least two directors who are directors on the date hereof
("Independent Directors"), provided that, in such event, if the number of
Independent Directors shall be reduced below two for any reason whatsoever, any
remaining Independent Directors (or Independent Director, if there be only one
remaining) shall be entitled to designate persons to fill such vacancies who
shall be deemed to be Independent Directors for purposes of this Agreement or,
if no Independent Director then remains, the other directors shall designate two
persons to fill such vacancies who shall not be stockholders, affiliates or
associates of Purchaser or Parent and such persons shall be deemed to be
Independent Directors for purposes of this Agreement. Notwithstanding anything
in this Agreement to the contrary, in the event that Purchaser's designees are
elected to the Company's Board, after the acceptance for payment of Shares
pursuant to the Offer and prior to the Effective Time, the affirmative vote of a
majority of the Independent Directors shall be required to (i) amend or
terminate this Agreement by the Company, (ii) exercise or waive any of the
Company's rights, benefits or remedies hereunder or (iii) take any other action
by the Company's Board under or in connection with this Agreement.

                                   ARTICLE II

                                   THE MERGER

      SECTION 2.1 The Merger. Upon the terms and subject to the satisfaction or
waiver of the conditions hereof, and in accordance with the applicable
provisions of this Agreement and the General Corporation Law of the State of
Delaware (the "GCL"), at the Effective Time Purchaser shall be merged (the
"Merger") with and into the Company. Following the Merger, the separate
corporate existence of Purchaser shall cease and the Company shall continue as
the surviving corporation (the "Surviving Corporation"). At the option of Parent
and provided that such amendment does not delay the Effective Time, the Merger
may be structured so that, and this Agreement shall thereupon be amended to
provide that, the Company shall be merged with and into Purchaser or another
direct or indirect wholly-owned subsidiary of Parent with Purchaser or such
other subsidiary of Parent continuing as the Surviving Corporation; provided,
however, that the Company shall be deemed not to have breached any of its
representations and warranties herein if and to the extent such breach would
have been attributable to such election.

      SECTION 2.2 Effective Time; Closing. As soon as practicable after the
satisfaction or waiver (to the extent permitted hereunder) of the conditions set
forth in Article VII, the Company shall execute in the manner required by the
GCL and deliver to the Secretary of State of the State of Delaware a duly
executed and verified certificate of merger, or, if permitted, a certificate of
ownership and merger, and the parties shall take such other and further actions
as may be required by law to make the Merger effective. The time the Merger
becomes effective in accordance with applicable law is referred to as the
"Effective Time." Prior to such filing, a closing (the "Closing") shall be held
at the offices of Bressler, Amery & Ross, 17 State Street, 34th Floor, New York,
New York 10004, or such other place as the parties hereto shall agree, for the
purpose of confirming the satisfaction or waiver of the conditions set forth in

Purchaser pursuant to the Offer for the purpose of considering and taking action
upon this Agreement;

            (ii) prepare and file with the SEC a preliminary proxy or

                                   ARTICLE III

                      DISSENTING SHARES; PAYMENT FOR SHARES

      SECTION 3.1 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 the GCL, if such Section 262 provides for appraisal rights for
such Shares in the Merger ("Dissenting Shares"), shall not be converted into the
right to receive the Purchase Price as provided in Section 2.7, unless and until
such holder fails to perfect or withdraws or otherwise loses his right to
appraisal and payment under the GCL. If, after the Effective Time, any such
holder fails to perfect or withdraws or loses his right to appraisal, such
Dissenting Shares shall thereupon be treated as if they had been converted as of
the Effective Time into the right to receive the Purchase Price, if any, to
which such holder is entitled, without interest or dividends thereon. The
Company shall give Parent prompt notice of any demands received by the Company
for appraisal of Shares and, prior to the Effective Time, Parent 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 Parent, make any payment with respect to, or settle or
offer to settle, any such demands.

      SECTION 3.2 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 Purchase Price of certificates (the
"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 Purchase Price multiplied by the number of Shares
formerly represented by each such Certificate, in exchange therefor, and each
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, Purchaser or the Company, or any
direct or indirect subsidiary thereof, or in the treasury of the Company) shall
represent solely the right to receive the Purchase Price. No interest shall be
paid or accrue on the Purchase Price. If the Purchase Price (or any portion
thereof) is to be delivered to any


                                       7


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 Purchase Price 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 Purchaser shall deposit, or
cause to be deposited, in trust with the Paying Agent such funds as needed for
timely payment hereunder; provided, however, that no such deposit shall relieve
Parent or Purchaser of their obligation to pay the Purchase Price pursuant to
Section 2.7.

      (c) The Purchase Price shall be invested by the Paying Agent as directed
by Parent, provided that 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 further that no loss on investment made pursuant to this Section 3.2(c)
shall relieve Parent or Purchaser of their obligation to pay the Purchase Price
pursuant to Section 2.7.

      (d) 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 Purchase Price in exchange
therefor.

      (e) 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 Purchase Price as provided in this Article III, subject to applicable
law in the case of Dissenting Shares.

      (f) 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 Purchase Price, without any interest
thereon.

                                   ARTICLE IV

                  REPRESENTATIONS AND WARRANTIES OF THE COMPANY

      The Company represents and warrants to Parent and Purchaser that:

      SECTION 4.1 Organization and Qualification; Subsidiaries. The Company is a
corporation duly organized, validly existing and in good standing under the laws
of the State of Delaware. Each entity which the Company owns, directly or
indirectly, a majority of the outstanding voting securities (each a "Subsidiary"
or collectively the "Subsidiaries") is a corporation duly organized, validly
existing and in good standing under the laws of the jurisdiction of its
incorporation. Each of the Company and its Subsidiaries has the requisite
corporate power and authority to own, operate or lease its properties and to
carry on its business as it is now being conducted, and is duly qualified or
licensed to do business, and is in good standing, in each jurisdiction in which
the nature of its business or the properties owned, operated or leased by it
makes such qualification, licensing or good standing necessary, except where the
failure to have such power or authority, or the failure to be so qualified,
licensed or in good standing, would not have a Material Adverse Effect on the
Company. The term "Material Adverse Effect on the Company," as used in this
Agreement, means any adverse change, circumstance or effect that, individually
or in the aggregate with all other adverse changes, circumstances and effects,
has had or will have a material adverse effect on the business, financial
condition, properties or results of operations of the Company and its
Subsidiaries taken as a whole, other than any adverse change, circumstance or
effect relating to or arising out of (i) the economy or securities markets in
general, (ii) the announcement of the Agreement or the transactions contemplated
hereby (including any impact on employees, vendors or customers resulting
therefrom) or (iii) the industry of the Company and its Subsidiaries in general,
and not specifically relating to the Company or its Subsidiaries.

      SECTION 4.2 Charter and By-laws. The Company has heretofore made available
to Parent a complete and correct copy of the charter and the By-laws or
comparable organizational documents, each as amended as of the date hereof, of
the Company and each of its Subsidiaries.

      SECTION 4.3 Capitalization.

      (a) The authorized capital stock of the Company consists of 12,000,000
shares of Common Stock, $.10 par value per share ("Common Stock") and 1,000,000
shares of preferred stock, par value $1.00 per share ("Preferred Stock"). As of
the close of business on May 15, 1998, 3,510,251 shares of Common Stock were
issued and outstanding, excluding 2,336,990 shares of Common Stock in treasury.
As of the date hereof there were no shares of Preferred Stock issued and
outstanding. The Company has no shares of capital stock reserved for future
issuance. The Company has no outstanding options to purchase any shares of
capital stock. Since March 31, 1998 the Company has not issued any shares of
capital stock. There are no bonds, debentures, notes or other indebtedness
having general voting rights (or convertible into securities having such rights)
("Voting Debt") of the Company or any of its Subsidiaries issued and
outstanding. There are no existing options, warrants, calls, subscriptions or
other rights, convertible securities, agreements, arrangements or commitments of
any character, relating to the issued or unissued capital stock of the Company
or any of its Subsidiaries, obligating the Company or any of its Subsidiaries to
issue, transfer or sell or cause to be issued, transferred or sold any shares of
capital stock or Voting Debt of, or other equity interest in, the Company or any
of its Subsidiaries or securities 


                                       9


convertible into or exchangeable for such shares or equity interests, and
neither the Company nor any of its Subsidiaries is obligated to grant, extend or
enter into any such option, warrant, call, subscription or other right,
convertible security, agreement, arrangement or commitment. There are no
outstanding contractual obligations of the Company or any of its Subsidiaries to
(i) repurchase, redeem or otherwise acquire any shares of capital stock of the
Company or any of its Subsidiaries or (ii) provide funds to or make any
investment in (in the form of a loan, capital contribution or otherwise) any
entity other than a wholly-owned Subsidiary.

      (b) Each of the outstanding shares of capital stock of each of the Company
and its Subsidiaries is duly authorized, validly issued, fully paid and
nonassessable, and such shares of capital stock of the Subsidiaries as are owned
by the Company or by a Subsidiary of the Company are owned in each case free and
clear of any lien, claim, option, charge, security interest, limitation,
encumbrance and restriction of any kind (any of the foregoing being a "Lien").
All outstanding shares of capital stock of each of the Subsidiaries are owned by
the Company.

      (c) There are no voting trusts or other agreements or understandings to
which the Company or any of its Subsidiaries is a party with respect to the
voting of the capital stock of the Company or any of its Subsidiaries.

      SECTION 4.4 Authority Relative to this Agreement.

      The Company has all necessary corporate power and authority to execute and
deliver this Agreement, and to consummate the transactions contemplated hereby
and thereby. The execution and delivery of this Agreement by the Company and the
consummation by the Company of the transactions contemplated hereby have been
duly and validly authorized and approved by the Board and no other corporate
proceedings on the part of the Company are necessary to authorize or approve
this Agreement, or to consummate the transactions contemplated hereby (other
than, with respect to the Merger, and subject to Section 2.10, the approval and
adoption of the Merger and this Agreement by the affirmative vote of the holders
of a majority of the Shares then outstanding). This Agreement has been duly and
validly executed and delivered by the Company and, assuming the due and valid
authorization, execution and delivery of this Agreement by Parent and Purchaser,
constitutes a valid and binding obligation of the Company enforceable against
the Company in accordance with its terms, except that such enforceability (i)
may be limited by bankruptcy, insolvency, moratorium or other similar laws
affecting or relating to the enforcement of creditors' rights generally and (ii)
is subject to general principles of equity.

      SECTION 4.5 No Conflict; Required Filings and Consents.

      (a) None of the execution, delivery or performance of this Agreement by
the Company, the consummation by the Company of the transactions contemplated
hereby or the compliance by the Company with any of the provisions hereof will
(i) conflict with or violate the Certificate of Incorporation or By-Laws of the
Company or the comparable organizational documents of any of its Subsidiaries,
(ii) conflict with or violate any statute, ordinance, rule, regulation, order,
judgment or decree applicable to the Company or its Subsidiaries, or by which
any of them or any of their respective properties or assets may be bound or
affected, or (iii) result in a violation or breach of or constitute a default
(or an event which with notice or lapse of time or both would become a default)
under, or give to others any rights of termination, amendment, acceleration or
cancellation of, or result in any loss of any material benefit, or 


                                       10


the creation of any Lien on any of the property or assets of the Company or any
of its Subsidiaries (any of the foregoing referred to in clause (ii) or this
clause (iii) being a "Violation") pursuant to, any note, bond, mortgage,
indenture, contract, agreement, lease, license, permit, franchise or other
instrument or obligation 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 properties may be bound or affected, except in the case of the
foregoing clauses (ii) or (iii) for any such Violations which would not in the
aggregate have a Material Adverse Effect on the Company or limit or restrict the
ability of the Company to consummate the transactions contemplated hereby or
thereby.

      (b) None of the execution, delivery or performance of this Agreement by
the Company, the consummation by the Company of the transactions contemplated
hereby or the compliance by the Company with any of the provisions hereof will
require any consent, waiver, approval, authorization or permit of, or
registration or filing with or notification to (any of the foregoing being a
"Consent"), any government or subdivision thereof, domestic, foreign or
supranational or any administrative, governmental or regulatory authority,
agency, commission, tribunal or body, domestic, foreign or supranational (a
"Governmental Entity"), except for (i) compliance with any applicable
requirements of the Securities Exchange Act of 1934, as amended (the "Exchange
Act"), (ii) the filing of a certificate of merger, or, if permitted, a
certificate of ownership and merger, pursuant to the GCL, (iii) notifications
required by certain state Blue Sky, takeover and environmental statutes, (iv)
compliance with the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as
amended (the "HSR Act") and any requirements of any foreign or supranational
Antitrust Laws, and (v) Consents, the failure of which to obtain or make would
not in the aggregate have a Material Adverse Effect on the Company or limit or
restrict the ability of the Company to consummate the transactions contemplated
hereby.

      SECTION 4.6 SEC Reports and Financial Statements.

      (a) The Company has filed with the SEC all forms, reports, schedules,
registration statements and definitive proxy statements required to be filed by

of normal recurring accruals considered necessary for a fair presentation have
been included.

      SECTION 4.7 Information. None of the information provided or that may be
provided by the Company for use in the Offer Documents, the Schedule 14D-1 or
any other document to be filed with the SEC or any other Governmental Entity in
connection with the transactions contemplated by this Agreement (the "Other
Filings"), and neither the Proxy Statement nor the Schedule 14D-9, shall, at the

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 or that may be provided by Parent or Purchaser specifically
for use in such documents. The Schedule 14D-9 and the Proxy Statement will

                             OF PARENT AND PURCHASER

      Parent and Purchaser represent and warrant to the Company that:

      SECTION 5.1 Organization and Qualification. Parent is a corporation duly
organized, validly existing and in good standing under the laws of Massachusetts
and each material subsidiary of Parent is a corporation duly organized, validly
existing and in good standing under the laws of the jurisdiction of its
organization. Purchaser is a corporation duly organized, validly existing and in
good standing under the laws of the State of Delaware. Each of Parent and its
material subsidiaries (including Purchaser) has the requisite corporate power

business as it is now being conducted, and is duly qualified or licensed to do
business, and is in good standing, in each jurisdiction in which the nature of
its business or the properties owned, operated or leased by it makes such
qualification, licensing or good standing necessary, except where the failure to
have such power or authority, or the failure to be so qualified, licensed or in
good standing, would not have a Material Adverse Effect on Parent. The term
"Material Adverse Effect on Parent," as used in this Agreement, means any
adverse change, circumstance or effect that, individually or in the aggregate
with all other adverse changes, circumstances and effects, has had or will have
a materially adverse effect on the business, financial condition, properties or

by Parent and Purchaser and the consummation by Parent and Purchaser of the
transactions contemplated hereby have been duly and validly authorized and
approved by the Boards of Directors of Parent and Purchaser and by Parent as
stockholder of Purchaser, and no other corporate proceedings on the part of
Parent or Purchaser are necessary to authorize or approve this Agreement, or to
consummate the transactions contemplated hereby. This Agreement has been duly
executed and delivered by each of Parent and Purchaser and, assuming the due and
valid authorization, execution and delivery by the Company, constitutes a valid
and binding obligation of each of Parent and Purchaser enforceable against each
of them in accordance with its terms, except that such enforceability (i) may be
limited by bankruptcy, insolvency, moratorium or other similar laws affecting or
relating to the enforcement of creditors' rights generally and (ii) is subject
to general principles of equity.

      SECTION 5.3 No Conflict; Required Filings and Consents.


                                       18

pursuant to any note, bond, mortgage, indenture, contract, agreement, lease,

Purchaser, or any of their subsidiaries, is a party or by which any of their
respective properties or assets may be bound or affected, except in the case of
the foregoing clauses (ii) and (iii) for any such violations which would not
have a Material Adverse Effect on Parent or limit or restrict the ability of
Parent or Purchaser to consummate the transactions contemplated hereby.

Purchaser, the consummation by Parent and Purchaser of the transactions
contemplated hereby or compliance by Parent and Purchaser with any of the
provisions hereof will require any Consent of any Governmental Entity, except
for (i) compliance with any applicable requirements of the Exchange Act, (ii)
the filing of a certificate of merger, or, if permitted, a certificate of
ownership and merger, pursuant to the GCL, (iii) notifications required by
certain state Blue Sky, takeover and environmental statutes, (iv) compliance
with the HSR Act and any requirements of any foreign or supranational Antitrust
Laws and (v) Consents the failure of which to obtain or make would not have a
Material Adverse Effect on Parent or limit or restrict the ability of Parent or
Purchaser to consummate the transactions contemplated hereby.

      SECTION 5.4 Information. None of the information provided or that may be
provided by Parent or Purchaser for use in the Proxy Statement, the Schedule
14D-9 or the Other Filings, and neither the Offer Documents nor the Schedule
14D-1, shall, at the time filed with the SEC or any other Governmental Entity,

respects with the provisions of the Exchange Act and the rules and regulations
thereunder.

authority with respect to the transactions contemplated by this Agreement, then
such party will endeavor in good faith to make, or cause to be made, as soon as
reasonably practicable and after consultation with the other party, an
appropriate response in compliance with such request. Parent will advise the
Company promptly in respect of any understandings, undertakings or agreements
(oral or written) which Parent proposes to make or enter into with the Federal
Trade Commission, the Department of Justice or any other domestic or foreign
government or governmental or multinational authority in connection with the
transactions contemplated by this Agreement.

      SECTION 6.5 Public Announcements. The mutual press release with respect to
the execution of this Agreement shall be a joint press release acceptable to
Parent and the Company. Thereafter, so long as this Agreement is in effect,
neither Parent and Purchaser, on the one hand, nor the Company, on the other,
shall issue any press release or otherwise make any public statement with
respect to the transactions contemplated by this Agreement without prior
consultation with the other party, except as may be required by law or as
contemplated by the first clause of Section 6.8(a)(ii) (it being understood and
agreed that the Company intends to file a Current Report on Form 8-K with
respect to the transaction contemplated hereby promptly after the date hereof).

      SECTION 6.6 Indemnification.

      (a) From and after the date hereof, Parent and Purchaser shall indemnify
and hold harmless each person who is, or has been at any time prior to the 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


                                       23


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
the GCL, for a period of not less than six years following the Effective Time;
provided, however, 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.

      (c) Without limitation of the foregoing, in the event any such Indemnified
Party is or becomes involved in any capacity in any action, proceeding or
investigation in connection with any matter, including, without limitation, the
transactions contemplated by this Agreement, occurring prior to, and including,
the Effective Time, Parent will pay as incurred such Indemnified Party's legal
and other expenses (including the cost of any investigation and preparation)
incurred in connection therewith, subject to the provision by such Indemnified
Party of an undertaking to reimburse such payments in the event of a final
determination by a court of competent jurisdiction that such Indemnified Party
is not entitled thereto. Subject to the undertaking to reimburse referred to in
the previous sentence, 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 6.6 or any action involving an
Indemnified Party resulting from the transactions contemplated by this
Agreement.

      (d) 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 Surviving Corporation's expense.

      (e) This Section 6.6 is intended to benefit the Indemnified Parties and
their respective heirs, executors and personal representatives and shall be
binding on the successors and assigns of Parent, Purchaser and the Surviving
Corporation.

      SECTION 6.7 Notification of Certain Matters. Parent and the Company shall
promptly notify each other of (a) the occurrence or non-occurrence of any fact
or event which would be reasonably likely (i) to cause any representation or
warranty contained in this Agreement to be untrue or inaccurate in any material
respect at any time from the date hereof to the Effective Time or (ii) to cause
any material covenant, condition or agreement under this Agreement not to be
complied with or satisfied in all material respects and (b) any failure of the
Company or Parent, as the case may be, to comply with or satisfy any covenant,
condition or agreement to be complied with or satisfied by it hereunder in any
material respect; provided, however, that no such notification shall affect the
representations or warranties of any party or the conditions to the obligations
of any party hereunder.

      SECTION 6.8 No Solicitation.


                                       24


      (a) The Company and its Subsidiaries shall not, and the Company and its
Subsidiaries shall ensure that their respective officers, directors and
consultants (including, but not limited to, investment bankers, attorneys and
accountants) and will use its best efforts to ensure that its employees,
representatives and agents do not, directly or indirectly, encourage, solicit,
participate in or initiate discussions or negotiations with, or provide any
information to, any corporation, partnership, person or other entity or group
(other than Purchaser, any of its affiliates or representatives) concerning any
proposal or offer to acquire all or a substantial part of the business or
properties of the Company or any of its Subsidiaries or any capital stock of the
Company or any of its Subsidiaries, whether by merger, tender offer, exchange
offer, sale of assets or similar transaction involving the Company or any
Subsidiary, division or operating or principal business unit of the Company (an
"Acquisition Proposal"), except that nothing contained in this Section 6.8 or
any other provision hereof shall prohibit the Company or the Company's Board
from (i) taking and disclosing to the Company's stockholders a position with
respect to a tender or exchange offer by a third party pursuant to Rules 14d-9
and 14e-2 promulgated under the Exchange Act, or (ii) making such disclosure to
the Company's stockholders as, in the good faith judgment of the Board, after
receiving advice from Company counsel, is required under applicable law;
provided that the Company may not, except as permitted by Section 6.8(b),
withdraw or modify its position with respect to the Offer or the Merger or
approve or recommend, or propose to approve or recommend any Acquisition
Proposal, or enter into any agreement with respect to any Acquisition Proposal.
Except as permitted by Section 6.8(b), the Company shall, and shall cause each
of its Subsidiaries to, immediately cease and cause to be terminated any
existing activities, discussions or negotiations by the Company, any of its
Subsidiaries or any officer, director, employee or affiliate of, or investment
banker, attorney, accountant or other advisor or representative of, the Company
or any of its Subsidiaries with parties conducted heretofore with respect to any
of the foregoing.

      (b) Notwithstanding the foregoing, the Company may furnish information
concerning the Company and its Subsidiaries to any corporation, partnership,
person or other entity or group pursuant to appropriate confidentiality
agreements with terms substantially similar to those contained in the
Confidentiality Agreement, and may negotiate and participate in discussions and
negotiations with such entity or group concerning an Acquisition Proposal if (i)
such entity or group, which has not been solicited by or on behalf of the
Company after the date hereof, has submitted a bona fide written proposal to the
Company relating to the acquisition of all or substantially all of the business
or properties of the Company and its subsidiaries or the acquisition of all of
the capital stock of the Company with respect to which the Board concludes in
good faith, after consulting with a nationally recognized investment banking
firm (including but not limited to Salomon Smith Barney), (A) the proposal is
more favorable to the Company's stockholders (in their capacities as
stockholders), from a financial point of view, than the Offer and the Merger and
(B) the bidder is fully capable of completing the transaction in accordance with
the terms of such proposal, and (ii) in the good faith opinion of the Board of
Directors of the Company, only after receipt of written advice from legal
counsel to the Company, the failure to provide such information or access or to
engage in such discussions or negotiations would cause the Board of Directors to
violate its fiduciary duties to the Company's stockholders under applicable law
(an Acquisition Proposal which satisfies clauses (i) and (ii) being referred to
herein as a "Superior Proposal"). The Company shall provide reasonable notice to
Purchaser to the effect that it has received an Acquisition Proposal, including
its terms and conditions (but excluding the identity of the party or parties
making such Acquisition Proposal, unless the terms and conditions of such
Acquisition Proposal contains a purchase price that includes stock of such party
or parties). At any time after 48 hours following notification to Purchaser of


                                       25


the Company's intent to do so (which notification shall include the identity of
the bidder and the material terms and conditions of the proposal) and if the
Company has otherwise complied with the terms of this Section 6.8(b), the Board
of Directors may withdraw or modify its approval or recommendation of the Offer
and may cause the Company to enter into an agreement with respect to a Superior
Proposal, provided it shall concurrently with entering into such agreement pay
or cause to be paid to Purchaser the Termination Fee (as defined below) plus any
amount payable at the time for reimbursement of expenses pursuant to Section
8.3(b). If the Company shall have notified Purchaser of its intent to enter into
an agreement with respect to a Superior Proposal in compliance with the
preceding sentence and has otherwise complied with such sentence, the Company
may enter into an agreement with respect to such Superior Proposal (with the
bidder and on terms no less favorable than those specified in such notification
to Purchaser) after the expiration of such 48 hour period.

                                   ARTICLE VII

                    CONDITIONS TO CONSUMMATION OF THE MERGER

consummation of the Merger.

      (c) Purchase of Shares. Parent and/or Purchaser shall have purchased all

however, that this condition shall not be applicable to the obligations of

                                  ARTICLE VIII

                         TERMINATION; AMENDMENTS; WAIVER

      SECTION 8.1 Termination. This Agreement may be terminated and the Merger
contemplated hereby may be abandoned at any time prior to the Effective Time,
notwithstanding approval thereof by the stockholders of the Company (with any
termination by Parent also being an effective termination by Purchaser):

      (a) by mutual consent of Parent and the Company;


                                       26


      (b) by Parent or the Company:

or ruling or taken any other action (which order, decree, ruling or other action
the parties hereto shall use their reasonable best efforts to lift) restraining,
enjoining or otherwise prohibiting the Merger and such order, decree, ruling or
other action shall have become final and nonappealable; or

      (ii) if (x) the Offer shall have expired without any Shares being
purchased therein or (y) Purchaser shall not have accepted for payment all
Shares tendered pursuant to the Offer by March 31, 1999; provided, however, that
the right to terminate this Agreement under this Section 8.1(b)(ii) shall not be
available to any party whose failure to fulfill any obligation under this
Agreement has been the cause of, or resulted in, the failure of Purchaser, to
purchase the Shares pursuant to the Offer on or prior to such date; or

      (iii) if the Supervisory Board of Wolters Kluwer nv shall not have
approved the transactions contemplated hereby by June 10, 1998.

      (c) by the Company:

            (i) if Parent and/or Purchaser fails to commence the Offer as
provided in Section 1.1 hereof; provided, that the Company may not terminate
this Agreement pursuant to this Section 8.1(c)(i) if the Company is at such time
in breach of its obligations under this Agreement such as to cause a Material
Adverse Effect on the Company;

            (ii) in connection with entering into a definitive agreement in
accordance with Section 6.8(b), provided it has complied with all provisions of
such section, including the notice provisions therein, and that it makes
simultaneous payment of the Termination Fee plus any amounts then due as a
reimbursement of expenses; or

            (iii) if Parent or Purchaser shall have made a material
misrepresentation or have breached in any material respect any of their
respective representations, covenants or other agreements contained in this
Agreement, which breach (a) cannot be or has not been cured, in all material
respects, within 30 days after the giving of written notice to Parent or
Purchaser, as applicable, and (b) limits or restricts the ability of Parent or
Purchaser to consummate the transactions contemplated hereby.

      (d) by Parent:

            (i) if prior to the purchase of Shares pursuant to the Offer, the
Company shall have breached any representation, warranty, covenant or other
agreement contained in this Agreement which (A) would give rise to the failure
of a condition set forth in paragraph (e) or (f) of Annex I hereto and (B)
cannot be or has not been cured, in all material respects, within 30 days after
the giving of written notice to the Company; or

            (ii) if any event set forth in paragraph (d) of Annex I hereto shall
have occurred.

      SECTION 8.2 Effect of Termination. In the event of the termination of this
Agreement


                                       27


pursuant to Section 8.1, this Agreement shall forthwith become void and have no
effect, without any liability on the part of any party or its directors,
officers or stockholders, other than the provisions of this Section 8.2, Section
8.3 and the last sentence of Section 6.2, which shall survive any such
termination. Nothing contained in this Section 8.2 shall relieve any party from
liability for any breach of this Agreement or the Confidentiality Agreement.

      SECTION 8.3 Fees and Expenses.

      (a) Except as contemplated by this Agreement, each party hereto shall bear
its own expenses and costs in connection with this Agreement and the
transactions contemplated hereby.

      (b) If

            (w) the Company shall terminate this Agreement pursuant to Section
8.1(c)(ii) hereof,

            (x) Parent shall terminate this Agreement pursuant to Section
8.1(d)(ii) hereof,

            (y) either the Company or Parent terminates this Agreement pursuant
to Section 8.1(b)(ii) and (a) prior thereto there shall have been publicly
announced another Acquisition Proposal (provided, however, that solely for
purposes of this clause (a), the term Acquisition Proposal shall not include (1)
the purchase of less than 5% of any class or series of capital stock of the
Company if such purchase does not involve an offer to acquire additional shares
of capital stock of the Company that could cause any person, entity or "group"
(as defined in Section 13(d)(3) of the Exchange Act), other than Purchaser or
its affiliates or any group of which any of them is a member, to beneficially
own 5% or more of any such class or series or (2) any purchase of 5% or more of
any class or series of capital stock of the Company which can properly be
reported on a Schedule 13G and (b) an Acquisition Proposal pursuant to which any
Person acquires all or a substantial part of the business or properties of the
Company or any of its Subsidiaries, any of the capital stock (or securities
exercisable for or convertible into such capital stock) of any of the
Subsidiaries of the Company or any capital stock (or securities exercisable for
or convertible into such capital stock) of the Company which represents 20% or
more of the equity interest or voting power of the Company shall be consummated
on or prior to March 31, 1999, or

            (z) Parent shall terminate this Agreement pursuant to Section
8.1(d)(i) hereof and an Acquisition Proposal pursuant to which any Person
acquires all or a substantial part of the business or properties of the Company
or any of its Subsidiaries, any of the capital stock (or securities exercisable
for or convertible into such capital stock) of any of the Subsidiaries of the
Company or any capital stock (or securities exercisable for or convertible into
such capital stock) of the Company which represents 20% or more of the equity
interest or voting power of the Company shall be consummated on or prior to
March 31, 1999,

then, the Company shall pay to Purchaser an amount equal to Seven Million Five
Hundred Thousand Dollars ($7,500,000)(the "Termination Fee"), plus an amount
equal to Purchaser's actual documented reasonable out-of-pocket fees and
expenses (including, without limitation, reasonable legal, investment banking,
financing commitment fees and commercial banking fees and expenses) incurred by
Purchaser and Parent in connection with the due diligence investigation, the
Offer, the Merger, this Agreement and 


                                       28


the consummation of the transactions contemplated hereby (the "Reimbursable
Expenses"), which shall be payable by wire transfer of same day funds to an
account designated by Purchaser. The Company shall also be obligated to pay to
Purchaser the Reimbursable Expenses in such manner if Parent shall terminate
this Agreement pursuant to Section 8.1(d)(i) hereof (regardless of whether an
Acquisition Proposal is consummated thereafter). The Termination Fee and
Purchaser's good faith estimate of its Reimbursable Expenses shall be paid
concurrently with any such termination, together with delivery of a written
acknowledgment by the Company of its obligation to reimburse Purchaser for its
actual expenses in excess of such estimated expenses payment, except that the
Termination Fee and such expenses shall be payable in connection with a
termination described in clauses (y) or (z) above upon the consummation of an
Acquisition Proposal referenced in such clauses. All fees and expenses paid
pursuant to this Section shall constitute liquidated damages and the Company
shall have no further liability to Purchaser or Parent under this Agreement
after the payment of such fees and expenses, provided that nothing in this
sentence shall affect any liability the Company may have to Purchaser or Parent
under Stock Purchase Agreements (if any) and the Option Agreement.

      SECTION 8.4 Amendment. This Agreement may be amended by Parent and the
Company at any time before or after any approval of this Agreement by the
stockholders of the Company but, after any such approval, no amendment shall be
made which decreases the Purchase Price or changes the form thereof without the
approval of such stockholders. This Agreement may not be amended except by an
instrument in writing signed on behalf of all the parties.

      SECTION 8.5 Extension; Waiver. At any time prior to the Effective Time,
any party hereto may (i) extend the time for the performance of any of the
obligations or other acts of any other party hereto, (ii) waive any inaccuracies
in the representations and warranties contained herein by any other party or in
any document, certificate or writing delivered pursuant hereto by any other
party or (iii) waive compliance with any of the agreements of any other party or
with any conditions to its own obligations. Any agreement on the part of any
party to any such extension or waiver shall be valid only if set forth in an
instrument in writing signed on behalf of such party.

                                   ARTICLE IX

                                  MISCELLANEOUS

to herein) and the letter agreement between Salomon Smith Barney, on behalf of
the Company, and Wolters Kluwer U.S. Corporation, on its own behalf and for
Parent and its other affiliates, dated April 6, 1998 (the "Confidentiality
Agreement"), constitute the entire agreement and supersede all prior agreements
and understandings, both written and oral, among the parties with respect to the
subject matter hereof and thereof.

      (b) Neither this Agreement nor any of the rights, interests or obligations
hereunder will be assigned by any of the parties hereto (whether by operation of
law or otherwise) without the prior written consent of the other party (except
that Parent may assign its rights and Purchaser may assign its rights, 


                                       29


interest and obligations to any affiliate or direct or indirect subsidiary of
Parent without the consent of the Company). Subject to the preceding sentence,
this Agreement will be binding upon, inure to the benefit of and be enforceable
by the parties and their respective successors and assigns.

      SECTION 9.3 Validity. The invalidity or unenforceability of any provision
of this Agreement shall not affect the validity or enforceability of any other

corporation or other legal entity.

      SECTION 9.11 Specific Performance. The parties hereto agree that

                                  SCHEDULE 4.16

                              ENVIRONMENTAL MATTERS

      Set forth below is a summary of the file maintained by the New Jersey
Department of Environmental Protection ("NJDEP") with respect to real property
located at 200 and 220 McGaw Drive, Edison Township, New Jersey, which Plenum
purchased on November 16, 1990. The NJDEP file was generated in connection with
the action taken by a prior owner, L. Perrigo Company ("Perrigo"), to comply
with the requirements of the Environmental Cleanup Responsibility Act ("ECRA").
This Act was subsequently amended and is now known as the Industrial Site
Recovery Act ("ISRA").

      Prior Owners and Operators

      On December 31, 1983, Albert Frassetto purchased the property from I.C.E.
Associates. He owned the property until it was sold to Plenum Publishing
Corporation ("Plenum"). The site consists of a warehousing space and two office
areas located on the main floor and on a mezzanine. From September 1979 through
August 1994 First National State Bank leased the mezzanine area for office
space. Thereafter, from September 1984 through December 1989 the New Jersey
Teachers Academy leased this space.

      ECRA

      The requirements of ECRA are triggered when an "industrial establishment"
terminates, transfers or closes its business activities. Industrial
establishments are defined in the statute as places of business which utilize
hazardous substances and have an Standard Industrial Classification Code ("SIC")
set out in the statute. The statute covers all manufacturing operations and
certain other activities. Perrigo intially took the position that the property
was not subject to the requirements of ECRA because of the owner's SIC code.
However, this analysis was incorrect because the SIC code of the property is
based upon the business operations undertaken at the facility. In this case,
NJDEP decided that the SIC code for Perrigo, the tenant was 51, an ECRA subject
activity.

      In July 1990, Perrigo submitted a request for an Administrative Consent
Order ("ACO") allowing the termination of activities before the ECRA
investigation and cleanup was completed. The company agreed to establish a
$500,000 financial assurance to secure its cleanup obligation.

      In October 1990, Perrigo submitted its General Information Submission
("GIS") and Site Evaluation Submission ("SES") forms to the NJDEP. These forms
generally discussed the business activities conducted at the site. In addition,
they showed that the primary environmental concern for the property was the
existence of two 4,000 gallon underground storage tanks ("USTs"). These USTs
were used for storage of No. 2 heating oil. No other environmental concerns
existed because the facility was used primarily for storage of finished and
packaged goods.

      Perrigo hired an environmental consultant to handle the closure of the
USTs and post-excavation sampling. In its report, the consultant stated that no
holes were noted in the tanks after they were removed from the ground. Further,
all post-excavation soil samples were well below the NJDEP's existing cleanup
limits. Based on this information, no further action was approved for these
areas of concern.


                                       42


      In a Report of Inspection, the NJDEP case manager also requested further
information concerning a hole observed in the facility's wall and floor drains.
Perrigo was able to resolve these issues by showing that the hole was related to
stormwater runoff from the roof, and the floor drains emptied to the sanitary
sewer line.

      Sale of Property to Plenum

      In October 1990, Frassetto advised the NJDEP that a contract to sell the
property to Plenum had been executed. An amendment to the ACO was executed. This
amendment authorized the transaction to close. However, no substantive cleanup
requirements were imposed because of its execution.

      On March 26, 1991, Perrigo submitted a Negative Declaration Affidavit
stating that the cleanup for the property was complete and performed in
accordance with NJDEP regulatory requirements. This Negative Declaration was
approved by NJDEP on April 3, 1991. With the issuance of this letter, the ECRA
review was closed.
