Wolters Kluwer U.S. Corporation, a Delaware corporation ("Parent"), disclosed in
a Tender Offer Statement on Schedule 14D-1, dated October 5, 1998 (the "Schedule

and subject to the conditions set forth in the Offer to Purchase, dated October

     The Offer is being made pursuant to an Agreement and Plan of Merger, dated

and the Company. The Merger Agreement provides, among other things, that as soon

ARRANGEMENTS WITH PARENT, NEWCO OR THEIR AFFILIATES

  Confidentiality Agreement

     The following is a summary of certain material provisions of the
Confidentiality Agreement, dated May 11, 1998, between the Company and Parent
(the "Confidentiality Agreement"). This summary does not purport to be complete
and is qualified in its entirety by reference to the complete text of the
Confidentiality Agreement, a copy of which is filed as Exhibit 2 hereto and is
incorporated herein by reference. Capitalized terms not otherwise defined below
shall have the meanings set forth in the Confidentiality Agreement.


                                       1

<PAGE>

     The Confidentiality Agreement contains customary provisions pursuant to
which, among other matters, Parent agreed to keep confidential all nonpublic and
confidential information furnished to it by the Company relating to the Company,
subject to certain exceptions (the "Confidential Information"), and to use the
Confidential Information solely for the purpose of evaluating a possible
transaction involving the Company and Parent. Parent has agreed in the
Confidentiality Agreement that for a period of twelve months from the date
thereof, without the prior written consent of the Company, neither it nor any of
its affiliates will, among other things, acquire or assist, advise, participate
with or encourage any other person in acquiring, directly or indirectly, control
of the Company or any securities, businesses or assets of the Company. Parent
has also agreed that for a period of twelve months from the date of the
Confidentiality Agreement not to request the Company or any of its
representatives, directly or indirectly, to amend or waive the provisions of the
foregoing sentence or take any action which might require the Company to make a
public announcement regarding the possibility of a transaction.

  The Merger Agreement

     The following is a summary of certain material provisions of the Merger
Agreement. This summary does not purport to be complete and is qualified in its
entirety by reference to the complete text of the Merger Agreement, a copy of
which is filed as Exhibit 1 hereto and is incorporated herein by reference.
Capitalized terms not otherwise defined below shall have the meanings set forth
in the Merger Agreement.

     The Offer. The Merger Agreement provides for the commencement of the Offer
not later than the fifth business day from the public announcement of the
execution of the Merger Agreement. The Merger Agreement also provides that Newco
cannot amend or waive the Minimum Condition (as defined below) or decrease the
Offer Price or the number of Shares sought, change the form of consideration to
be paid pursuant to the Offer, impose conditions to the Offer in addition to
those set forth in Annex A to the Merger Agreement, amend any other term or
condition of the Offer in any manner adverse to the holders of Shares or extend
the expiration date of the Offer without the prior written consent of the
Company. Notwithstanding the foregoing provisions, (a) Parent has agreed to
cause Newco to extend the Offer at any time prior to the termination of the
Merger Agreement in periods of ten business days for each such extension, if,
and to the extent that, at the initial expiration date of the Offer, or any
extension thereof, all conditions to the Offer have not been satisfied or waived
and (b) the Offer Price may be increased and the Offer may be extended to the
extent required by law in connection with such increase. In addition, Newco may,
without the consent of the Company, extend the Offer for a period of not more
than ten business days beyond the latest expiration date that would otherwise be
permitted under the immediately preceding sentence if there shall not have been
tendered and not withdrawn pursuant to the Offer at least 90% of the outstanding
Shares.

     The obligation of Newco to accept for payment and pay for Shares tendered
pursuant to the Offer is subject to the condition that there will be validly
tendered and not withdrawn a number of Shares which, together with any Shares
beneficially owned by Parent or Newco, represent at least a majority of the
Shares outstanding on a fully diluted basis (the "Minimum Condition"). In
addition, Newco is not required to accept for payment or pay for any Shares
tendered pursuant to the Offer, and may terminate the Offer and not accept for
payment any tendered Shares, if (a) any applicable waiting period under the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the "HSR
Act"), or the antitrust laws of applicable jurisdictions outside the United
States, has not expired or been terminated prior to the expiration of the Offer;
(b) at any time on or after September 29, 1998, and before the expiration of the
Offer any of the following occur: (i) there shall be any statute, rule,
regulation, judgment, order or injunction promulgated, entered, enforced,
enacted, issued or applicable to the Offer or the Merger by any governmental
entity of competent jurisdiction in the United States or other country in which
the Company directly or indirectly has material assets or operations which (A)
prohibits the consummation of the Offer or the Merger, (B) as a result of the
Offer or the Merger, restrains or prohibits or imposes any material limitations
on Parent's or Newco's ownership or operation of all or a material portion of
the businesses or assets of the Company and its Subsidiaries (as defined below),
taken as a whole, or of Parent and its Subsidiaries, taken as a whole, or
compels Parent or any of its Subsidiaries or affiliates to dispose of or hold
separate all or any material portion of the business or assets of the Company
and its Subsidiaries, taken as a whole, or of Parent and its Subsidiaries, taken
as a whole, or requires the Company, Parent or Newco to pay damages that are
material in relation to the Company and its Subsidiaries, taken as a whole, (C)
challenges, prohibits, or makes illegal the acceptance for payment, payment for
or purchase of Shares pursuant to, or consummation of, the Offer or the Merger,
(D) imposes material limitations on the ability of Newco or Parent effectively
to exercise full rights of ownership of the Shares accepted for payment pursuant
to the Offer, including, without limitation, the right to vote the Shares
purchased by it on all matters properly presented to the


                                       2

<PAGE>

Company's stockholders, or (E) requires divestiture by Parent or any of its
Subsidiaries or affiliates of any Shares, provided that Parent shall have used
all reasonable efforts to cause any such judgment, order or injunction to be
vacated or lifted; (ii) there shall be instituted or pending any action, suit or
proceeding by any governmental entity of competent jurisdiction in the United
States or any other country in which the Company or Parent directly or
indirectly has material assets or operations, that is reasonably likely,
directly or indirectly, to result in any of the consequences referred to in
clauses (A) through (E) above; provided that Parent shall have used all
reasonable efforts to cause any such action, suit or proceeding to be withdrawn
or dismissed; (iii) there has been since September 29, 1998, any event,
occurrence or development or state of circumstances or facts which has had or
would reasonably be expected to have a Company Material Adverse Effect (as
defined below); (iv) the representations and warranties of the Company set forth
in the Merger Agreement shall not be true and accurate as of the date of
consummation of the Offer as though made on or as of such date or the Company
shall have breached or failed in any material respect to perform or comply with
any material obligation, agreement or covenant required by the Merger Agreement
to be performed or complied with by it except, (i) those representations and
warranties that address matters only as of a particular date or only with
respect to a specified period of time which need only be true and accurate as of
such date or with respect to such period or (ii) where the failure of such
representations and warranties to be true and accurate or the breach,
non-performance or non-compliance with such obligations, agreements or
covenants, do not have, individually or in the aggregate, or would not
reasonably be expected to have, individually or in the aggregate, a Company
Material Adverse Effect; (v) the Merger Agreement shall have been terminated in
accordance with its terms; (vi) the Company shall have entered into a definitive
agreement or agreement in principle with any person with respect to an
Alternative Proposal (as defined below); or (vii) the Company Board shall have
withdrawn, modified or changed in a manner adverse to Parent or Newco (including
by amendment of the Schedule 14D-9) its recommendation of the Offer, the Merger
Agreement or the Merger or shall have recommended an Alternative Proposal (as
defined below) or the Company Board shall have adopted a resolution to do any of
the foregoing, which in the sole judgment of Parent or Newco in any such case,
and regardless of the circumstances giving rise to such condition, makes it
inadvisable to proceed with the Offer and/or with such acceptance for payment or
payments.

     For purposes of the Merger Agreement, "Subsidiary" means, when used with
reference to any entity, any corporation a majority of the outstanding voting
securities of which are owned directly or indirectly by such entity. "Company
Material Adverse Effect" means any adverse change in the assets, liabilities,
financial condition, or results of operations of the Company or any of its
Subsidiaries which is material to the Company and its Subsidiaries taken as a
whole, other than any change or effect arising out of general economic
conditions. "Alternative Proposal" means any proposal or offer for a merger,
asset acquisition or other business combination involving the Company or any
proposal or offer to acquire a significant equity interest in, or a significant
portion of the assets of, the Company other than the transactions contemplated
by the Merger Agreement. "Superior Proposal" means any bona fide proposal to
acquire, directly or indirectly, all of the Shares then outstanding or all or
substantially all the assets of the Company, and otherwise on terms which the
Company Board determines in good faith (after consultation with the Company's
financial advisor) to be more favorable to the Company and its stockholders than
the Offer and the Merger.

     The Merger. The Merger Agreement provides that, subject to the terms and
conditions thereof, Newco will be merged with and into the Company, with the
Company continuing as the Surviving Corporation and a wholly owned indirect
subsidiary of Parent, and each issued and outstanding Share (other than Shares
owned by Parent, Newco or any other wholly owned subsidiary of Parent, Shares
owned by the Company as treasury stock and Shares held by stockholders who have
properly exercised appraisal rights under Delaware law, if any) shall be
converted into the right to receive the Offer Price, without interest. Each
issued and outstanding Share of Newco common stock shall be converted into and
become one fully paid and nonassesable share of Common Stock of the Surviving
Corporation. The Merger Agreement also provides that (i) the directors and
officers of Newco immediately prior to the effective time of the Merger (the
"Effective Time") will be the initial directors and officers, respectively of
the Surviving Corporation; (ii) the Certificate of Incorporation of the Company
will be the initial Certificate of Incorporation of the Surviving Corporation;
and (iii) the By-laws of Newco will be the initial By-laws of the Surviving
Corporation.

     Treatment of Options. The Merger Agreement provides that as of the
Effective Time, each outstanding option (an "Option," and collectively, the
"Options") to purchase Shares which has been granted under either the Company's
1990 Stock Option Plan or 1993 Stock Option Plan (the "Stock Plans"), whether or
not then vested or exercisable, will be converted into the right to receive from
the Company an amount of cash equal to the product of (A) the number of Shares
subject to such Option and (B) the excess, if any, of the Offer Price over the
per share exercise price (the "Option Consideration"). Prior to the Effective
Time, the Company will take all steps necessary to


                                       3

<PAGE>

give written notice to each holder of an Option that (i) all Options shall be
canceled effective as of the Effective Time and (ii) upon the execution and
delivery to the Company by such holder of an instrument acknowledging
cancellation of all Options held by such holder effective as of the Effective
Time ("Cancellation Instrument"), the Company will pay such holder, promptly
following the Effective Time, the Option Consideration for all Options held by
such holder. The Company Board and its Compensation Committee will take any and
all action necessary to effectuate the matters described in this provision on or
before the Effective Time. Parent has agreed to provide the Company with
sufficient funds to permit the Company to satisfy its obligations under this
provision.

     Directors. The Merger Agreement provides that, promptly upon the purchase
of and payment for Shares by Parent or any of its Subsidiaries which represent
at least a majority of the outstanding Shares (on a fully diluted basis), Parent
will be entitled to designate such number of directors, rounded up to the next
whole number, on the Company Board, subject to compliance with Section 14(f) of
the Securities Exchange Act of 1934, as amended (the "Exchange Act"), and Rule
14f-1 promulgated thereunder, as is equal to the product of the total number of
directors on the Company Board (giving effect to the directors elected pursuant
to this sentence) multiplied by the percentage that the aggregate number of
Shares beneficially owned by Parent, Newco and any of their affiliates bears to
the total number of Shares then outstanding. The Company will take all action
necessary to cause Parent's designees to be elected or appointed to the Company
Board and to secure the resignations of such number of its incumbent directors
as is necessary to cause Parent's designees to be elected or appointed to the
Company Board and to secure the resignations of such number of its incumbent
directors as is necessary to enable Parent's designees to be so elected to the
Company Board and will cause Parent's designees to be so elected. The Company
will take all action necessary to cause individuals designated by Parent to
constitute the same percentage as such individuals represent on the Company
Board of each committee of the Company Board and each board of directors (and
committee thereof) of each of the Company's Subsidiaries. Notwithstanding the
foregoing, until the Effective Time, the Company will have on the Company Board
at least two directors who were directors of the Company on the date of the
Merger Agreement (the "Company Designees"); provided, that, subsequent to the
purchase of and payment for Shares pursuant to the Offer, Parent will always
have its designees represent at least a majority of the entire Company Board.

     The Merger Agreement also provides that from and after the time, if any,
that Parent's designees constitute a majority of the Company Board, any
amendment of the Merger Agreement, any termination of the Merger Agreement by
the Company, any extension of time for performance of any of the obligations of
Parent or Newco, any waiver of any condition or any of the Company's rights
thereunder or any actions that would adversely affect the rights of the
stockholders of the Company or the holders of Options with respect to the
transactions contemplated thereby, may be effected only by the action of a
majority of the Company Designees then in office, which action shall be deemed
to constitute the action of the full Company Board; provided, that if the number
of Company Designees shall be reduced below two for any reason whatsoever, any
remaining Company Designee shall be entitled to designate a person to fill such
vacancy who shall be deemed to be a Company Designee for purposes of the Merger
Agreement or, if no Company Designee then remains, the other directors shall
designate two persons to fill such vacancies who shall not be stockholders,
affiliates or associates of Newco or Parent and such persons shall be deemed to
be Company Designees for purposes of the Merger Agreement.

     Stockholders' Meeting. Pursuant to the Merger Agreement, the Company, if
required by applicable law in order to consummate the Merger, shall duly call,
give notice of, convene and hold a special meeting of its stockholders as soon
as practicable following the acceptance for payment and purchase of Shares by
Newco pursuant to the Offer for the purpose of considering and taking action
upon the Merger Agreement.

     The Merger Agreement also provides that the Company shall, if required by
applicable law in order to consummate the Merger, prepare and file with the
Commission a preliminary proxy or information statement relating to the Merger
and the Merger Agreement and shall (i) obtain and furnish the information
required to be included by the Commission in the Proxy Statement (as hereinafter
defined) and, after consultation with Parent, respond promptly to any comments
made by the Commission with respect to the preliminary proxy or information
statement and cause a definitive proxy or information statement (the "Proxy
Statement") to be mailed to its stockholders and (ii) obtain the necessary
approvals of the Merger and the Merger Agreement by its stockholders. The Merger
Agreement also provides that, subject to the fiduciary obligations of the
Company Board, the Company shall include in the Proxy Statement the
recommendation of the Company Board that stockholders of the Company vote in
favor of the approval of the Merger and the adoption of the Merger Agreement.
The Merger Agreement also provides that, in the event that Parent, Newco or any
other Subsidiary of Parent shall acquire at least 90% of the Shares, pursuant to
the Offer or


                                       4

<PAGE>

otherwise, the parties thereto shall take all necessary and appropriate action
to cause the Merger to become effective as soon as practicable after such
acquisition, without a meeting of the Company's stockholders in accordance with
Section 253 of the Delaware General Corporation Law (the "DGCL").

     Representations and Warranties. The Merger Agreement contains
representations and warranties of one or more of the parties with respect to,
among other things, (i) organization, good standing, corporate power and
authority and enforceability, (ii) capitalization, (iii) required consents or

     Interim Operations. In the Merger Agreement, the Company has covenanted and

the Effective Time, unless Parent otherwise agrees in writing and except as
otherwise contemplated by the Merger Agreement, (a) the Company will conduct its
operations according to its ordinary and usual course of business consistent
with past practice and seek to preserve intact its current business
organization, keep available the services of its current officers and employees

of business consistent with past practice, take any action to fund or in any
other way secure the payment of compensation or benefits under any employee
plan, agreement, contract or arrangement or Benefit Plan; or (xiv) take, or
agree to take, any action that would make any representation or warranty of the
Company in the Merger Agreement inaccurate at the Effective Time (except for
representations and warranties which speak as of a particular date, which need
be accurate only as of such date) or omit, or agree to commit to omit, to take
any action necessary to prevent any such representation or warranty from being
inaccurate in any material respect at the Effective Time (except for
representations and warranties which speak as of a particular date, which need
be accurate only as of such date), provided however that the Company will be
permitted to take or omit to take such action which can be cured, and in fact is
cured, at or prior to the Effective Time, or take any action that would result
in, or is reasonably likely to result in, any of the conditions of the Merger
set forth in Article VI of the Merger Agreement not being satisfied except that,
with respect to the condition set forth in Section 6.1(a) of the Merger
Agreement, such action shall be permitted if it is consistent with the fiduciary
duties of the Company Board to the Company's stockholders under applicable law;
or (xv) authorize, recommend, propose or announce an intention to do any of the
foregoing, or enter into any contract, agreement, commitment or arrangement to
do any of the foregoing.

     Alternative Proposals. Pursuant to the Merger Agreement, the Company has
agreed that it (a) will not, and will cause its officers, directors, employees,
representatives and agents not to, initiate, solicit or encourage, directly or
indirectly, any Alternative Proposal or engage in any negotiations or enter into
any agreement or provide any confidential information or data to any person in
connection with or relating to any Alternative Proposal; (b) will immediately
cease any existing discussions or negotiations, if any, with any parties
conducted heretofore with respect to any Alternative Proposal; and (c) will
notify Parent as soon as practicable if any such inquiries or proposals are
received by, any such information is requested from, or any such negotiations
and/or discussions are sought to be initiated or continued with, the Company.
Notwithstanding the foregoing, nothing in such provision shall require the
Company Board on behalf of the Company to act, or refrain from acting with
respect to unsolicited Alternative Proposals in any manner which, in the opinion
of the Company Board after consultation with its counsel, could reasonably be
deemed inconsistent with its fiduciary duties to the Company's stockholders
under applicable law, including, without limitation, disclosing to its
stockholders a position required by Rule 14e-2(a) under the Exchange Act.

     Directors' and Officers' Insurance and Indemnification. The Merger
Agreement provides that (a) from and after the consummation of the Offer, Parent
will, and will cause the Company (or the Surviving Corporation if after the
Effective Time) to, indemnify, defend and hold harmless any current or former
officer or director of the Company (the "Company Indemnified Party") and its
Subsidiaries against all losses, claims, damages, liabilities, costs and
expenses (including attorney's fees and expenses), judgments, fines, losses, and
amounts paid in settlement in connection with any actual or threatened action,
suit, claim, proceeding or investigation (each a "Claim") to the extent that any
such Claim is based on, or arises out of the fact that such person is or was a
director or officer of the Company or any of its


                                       6

<PAGE>

Subsidiaries, and to the extent that any such Claim pertains to any matter or
fact arising out of any act or omission prior to or at the Effective Time,
regardless of whether such Claim is asserted or claimed prior to, at or after
the Effective Time, to the full extent permitted under applicable law or the
Company's Certificate of Incorporation, By-laws or indemnification agreements in
effect on the date of the Merger Agreement and disclosed in a schedule thereto
or otherwise as permitted by any such contracts, including provisions relating
to advancement of expenses incurred in the defense of any action or suit.
Without limiting the foregoing, in the event any Company Indemnified Party
becomes involved in any capacity in any Claim, then from and after consummation
of the Offer, Parent shall, or shall cause the Company (or the Surviving
Corporation if after the Effective Time) to, periodically advance to such
Company Indemnified Party its legal and other expenses (including the cost of
any investigation and preparation incurred in connection therewith), subject to
the provision by such Company Indemnified Party of an undertaking to reimburse
the amounts so advanced in the event of a final non-appealable determination by
a court of competent jurisdiction that such Company Indemnified Party is not
entitled thereto; (b) Parent and the Company agree that all rights to
indemnification and all limitations on liability existing in favor of the
Company Indemnified Party as provided in the Company's Certificate of
Incorporation and By-laws as in effect as of the date of the Merger Agreement
shall survive the Merger and shall continue in full force and effect, without
any amendment thereto, for a period of six years from the Effective Time to the
extent such rights are consistent with the DGCL; 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
disposition of any and all such claims; provided, further, that nothing in such
section shall impair any rights or obligations of any present or former
directors or officers of the Company; (c) Parent shall cause to be maintained in
effect for the Indemnified Parties (as defined below) for not less than six
years after the Effective Time policies of directors' and officers' liability
insurance and fiduciary liability insurance with respect to matters occurring at
or prior to the Effective Time (including, without limitation, the transactions
contemplated by the Merger Agreement) providing substantially the same coverage
and containing terms and conditions which are no less advantageous, in any
material respect, to those currently maintained by the Company for the benefit
of the Company's present or former directors, officers, employees or agents
covered by such insurance policies prior to the Effective Time (the "Indemnified
Parties"); and (d) in the event Parent or Newco or any of their successors or
assigns (i) consolidates with or merges into any other person and shall not be
the continuing or surviving corporation or entity of such consolidation or
merger, or (ii) transfers or conveys all or substantially all of its properties
and assets to any person, then, and in each such case, to the extent necessary
to effectuate the purposes of such section, proper provision shall be made so
that the successors and assigns of Parent and Newco assume the obligations set
forth above and none of the actions described in clauses (i) or (ii) shall be
taken until such provision is made.

     Employees. The Merger Agreement provides that, (a) following the Effective
Time, the Surviving Corporation will provide pension, health and welfare
benefits (other than stock option, stock purchase or similar plans) to employees
of the Company and its Subsidiaries who continue their employment after the
Effective Time (each, a "Continuing Employee") on terms which are generally no
less favorable to such Continuing Employee than the benefits being provided to
such Continuing Employee immediately prior to the Effective Time and (b) if at
any time Parent shall make a determination that any Continuing Employee is
eligible to participate in any of Parent's benefit plans after the Effective
Time, then, for purposes of eligibility and vesting with respect to any such
plans, Parent will cause the Surviving Corporation to recognize the service of
the Continuing Employees through the Effective Time as if such service had been
performed with Parent.

     Conditions to the Merger. The Merger Agreement provides that the respective
obligations of each party to effect the Merger shall be subject to the
satisfaction, at or prior to the Effective Time, of the following conditions:
(a) if approval of the Merger by the stockholders is required by applicable law,
the Merger Agreement shall have been approved and adopted by the requisite vote
of the Company's stockholders; provided, that Parent and Purchaser are required
to vote all of their Shares in favor of the Merger; (b) there shall not be in
effect any statute, rule, regulation, executive order, decree, ruling or
injunction or other order of a court or governmental or regulatory agency of
competent jurisdiction directing that the transactions contemplated in the
Merger Agreement not be consummated or otherwise materially limiting or
restricting ownership or the operation of the business of the Surviving
Corporation; provided, however, that, subject to the terms and conditions set
forth in the Merger Agreement, prior to invoking such condition each party shall
use its reasonable efforts to have any such decree, ruling, injunction or order
vacated; (c) subject to the terms and provisions set forth in the Merger
Agreement, all governmental consents, orders and approvals legally required for
the consummation of the Merger and the transactions contemplated thereby shall
have been obtained and be in effect at the Effective Time, other than those
consents, orders or approvals which would not


                                       7

<PAGE>

reasonably be expected to have a Company Material Adverse Effect or which would
prohibit or materially limit or restrict the consummation of the transactions
contemplated therein or the ownership or operation of the business of the
Surviving Corporation, and the waiting periods under the HSR Act and under
antitrust laws of applicable jurisdictions outside the United States shall have
expired or been terminated.

     Termination. The Merger Agreement provides that it may be terminated at any
time prior to the Effective Time: (a) by the mutual consent of Parent, Newco and
the Company; (b) by either the Company or Parent (i) if shares of Company Common
Stock shall not have been purchased pursuant to the Offer on or prior to three
(3) months from the execution of the Merger Agreement; provided, however, that
the passage of the period referred to in the foregoing clause shall be tolled
during (A) the period during which any party shall be subject to a non-final
order, decree, ruling or action restraining, enjoining or otherwise prohibiting
the purchase of shares of Company Common Stock pursuant to the Offer or the
consummation of the Merger, but not later than six (6) months from the execution
of this Agreement, or (B) any additional waiting period under the HSR Act
resulting from a second request; provided, further, however, that the right to
terminate the Merger Agreement under such clause shall not be available to any
party whose failure to fulfill any obligation under the Merger Agreement has
been the cause of, or resulted in, the failure of Parent or Newco, as the case
may be, to purchase shares of Company Common Stock pursuant to the Offer on or
prior to such date; or (ii) if any governmental entity of competent jurisdiction
in the United States or other country in which the Company directly or
indirectly has material assets or operations shall have issued an order, decree
or ruling or taken any other action (which order, decree, ruling or other action
the parties hereto shall use their respective reasonable best efforts to lift),
in each case permanently restraining, enjoining or otherwise prohibiting the
transactions contemplated by the Merger Agreement and such order, decree, ruling
or other action shall have become final and non-appealable; (c) by the Company
(i) if prior to the purchase of Shares pursuant to the Offer, (A) the Company
Board shall have entered into or shall have publicly announced its intention to
enter into an agreement or an agreement in principle with respect to any
Alternative Proposal that the Company Board determines, in good faith after
consultation with its financial advisors, is a Superior Proposal; (B) the
Company Board shall have withdrawn, or modified or changed in a manner adverse
to Parent or Newco its approval or recommendation of the Offer, the Merger
Agreement or the Merger or shall have recommended a Superior Proposal or shall
have executed, or shall have announced its intention to enter into, an agreement
in principle or definitive agreement relating to a Superior Proposal with a
person or entity other than Parent, Newco or their affiliates (or the Company
Board resolves to do any of the foregoing); (C) any person or group (as defined
in Section 13(d)(3) of the Exchange Act) (other than Parent, Newco or any
affiliate thereof or Mark L. Nelson) shall have become, after the date of the
Merger Agreement, the beneficial owner (as defined in Rule 13d-3 promulgated
under the Exchange Act) of a majority of the outstanding Shares, or (D) any
representation or warranty made by Parent or Newco in the Merger Agreement shall
not have been true and correct in all material respects when made, or Parent or
Newco shall have failed to observe or perform in any material respect any of its
material obligations under the Merger Agreement; provided that prior to
exercising such right of termination, the Company shall give prompt written
notice to Parent of such misrepresentation or breach of warranty or failure to
observe or perform; provided, further, that the Company shall not have such
right of termination if the condition resulting in such misrepresentation or
breach of warranty or failure to observe or perform is cured (x) in the event
such notice is delivered on or prior to the fourth business day prior to the
then-scheduled expiration date of the Offer, not later than the earlier of (A)
such expiration date and (B) ten business days following delivery of such notice
and (y) in the event such notice is delivered on or after the third business day
prior to such expiration date, not later than three business days following such
delivery (it being agreed that in such event the Offer shall be extended as
necessary at least until the end of such cure period); or (ii) if Parent or
Newco shall have terminated the Offer, or the Offer shall have expired, without
Parent or Newco, as the case may be, purchasing any Shares pursuant thereto;
provided that the Company may not terminate the Merger Agreement pursuant to
such provision if the Company is in material breach of the Merger Agreement; or
(iii) if Parent, Newco or any of their affiliates shall have failed to commence
the Offer on or prior to five business days following the date of the initial
public announcement of the Offer; provided, that the Company may not terminate
the Merger Agreement pursuant to such provision if the Company is in material
breach of the Merger Agreement; or (d) by Parent or Newco (i) if, due to an
occurrence that if occurring after the commencement of the Offer would result in
a failure to satisfy any of the conditions to the Offer, Parent, Newco, or any
of their affiliates shall have failed to commence the Offer on or prior to five
business days following the date of the initial public announcement of the
Offer; provided that Parent may not terminate the Merger Agreement pursuant to
such provision if Parent or Newco is in material breach of the Merger Agreement;
(ii) prior to the purchase of shares of Company Common Stock pursuant to the
Offer, if (A) the Company shall have received any


                                       8

<PAGE>

Alternative Proposal which the Company Board has determined to designate as a
Superior Proposal; (B) the Company Board shall have withdrawn, or modified or
changed in a manner adverse to Parent or Newco its approval or recommendation of
the Offer, the Merger Agreement or the Merger or shall have recommended an
Alternative Proposal or shall have executed, or shall have announced its
intention to enter into, an agreement in principle or definitive agreement
relating to an Alternative Proposal with a person or entity other than Parent,
Newco or their affiliates (or the Company Board resolves to do any of the
foregoing); (C) any person or group (as defined in Section 13(d)(3) of the
Exchange Act) (other than Parent, Newco or any affiliate thereof or Mark L.
Nelson) shall have become, after the date of the Merger Agreement, the
beneficial owner (as defined in Rule 13d-3 promulgated under the Exchange Act)
of 50% or more of the outstanding Shares, or (D) any representation or warranty
made by the Company in the Merger Agreement shall not have been true and correct
in all material respects when made and shall have resulted in, or is reasonably
likely to result in, a Company Material Adverse Effect, or the Company shall
have failed to observe or perform in any material respect any of its material
obligations under the Merger Agreement; provided that prior to exercising such
right of termination, Parent and Newco shall give prompt written notice to the
Company of such misrepresentation or breach of warranty or failure to observe or
perform; provided, further, that Parent and Newco shall not have such right of
termination if the condition resulting in such misrepresentation or breach of
warranty or failure to observe or perform is cured (i) in the event such notice
is delivered on or prior to the fourth business day prior to the then-scheduled
expiration date of the Offer, not later than the earlier of (A) such expiration
date and (B) ten business days following delivery of such notice and (ii) in the
event such notice is delivered on or after the third business day prior to such
expiration date, not later than three business days following such delivery (it
being agreed that in such event the Offer shall be extended as necessary at
least until the end of such cure period).

     Effect of Termination; Termination Fee. The Merger Agreement provides that
if the Company terminates the Merger Agreement pursuant to the provisions
described in clauses (c)(i)(A), (B) and (C) under "Termination" above or if
Parent or Newco terminates the Merger Agreement pursuant to the provisions
described in clauses (d)(ii)(A), (B) and (C) under "Termination" above, then
immediately following such termination, the Company shall pay to Parent
$7,000,000 in full satisfaction of the obligations of the Company under the
Merger Agreement plus Parent's and Newco's reasonable out of pocket fees and
expenses, not to exceed $500,000, incurred in connection with the due diligence
investigation, the Offer, the Merger, the Merger Agreement and the consummation
of the transactions thereunder. Nothing contained in such provision shall
relieve any party from liability for fraud or for willful breach of the Merger
Agreement.

     Except as set forth above, whether or not the Merger is consummated, all
costs and expenses incurred in connection with the Merger Agreement and the
transactions contemplated thereby shall be paid by the party incurring such
expenses.

     Amendment. The Merger Agreement provides that after approval of the Merger
Agreement by the stockholders of the Company, no amendment shall be made which
reduces or changes the consideration payable in the Merger or adversely affects
the rights of the Company's stockholders without the approval of such
stockholders.

  Stock Option and Tender Agreement

     Concurrently with the execution of the Merger Agreement, Parent and Newco
entered into a Stock Option and Tender Agreement (the "Stock Option Agreement")
with Mark L. Nelson, Deborah Hull, Carleen Nelson and Martin Kahn (the
"Stockholders") with respect to Shares owned by such Stockholders. The following
summary of the Stock Option Agreement does not purport to be complete and is
qualified in its entirety by reference to the complete text of the Stock Option
Agreement which is attached as Exhibit 3 hereto and is incorporated by
reference.

     Pursuant to the Stock Option Agreement, the Stockholders have agreed to
tender their Shares in the Offer and have granted Parent or Newco, as Parent
shall designate (the "Optionee"), an irrevocable option (the "Stock Option") to
purchase all of the outstanding Shares owned by such holders from time to time
at a purchase price equal to the Offer Price. The Stock Option may be exercised
by Parent or Newco, but only as to all of such Stockholders and as to all of
their Shares, if (i) the Offer is terminated by Parent or Newco because (A) the
Company shall have entered into a definitive agreement or an agreement in
principle for an Alternative Proposal or (B) the Company's Board of Directors
shall have withdrawn, modified or changed in a manner adverse to Parent or Newco
its recommendation of the Offer, the Merger Agreement or the Merger or
recommended an Alternative Proposal or resolved to do any of the foregoing, or
(ii) if the Offer expires without the purchase of Shares thereunder and at the
time of such expiration (x) the Minimum Condition was not satisfied or (y)
circumstances had occurred giving rise to a right of termination for the reasons
set 


                                       9

<PAGE>

forth in subclauses (i)(A) and (B) of this sentence, in each case without any
violation of the Offer or the Merger Agreement by Parent or Newco. Parent may
also exercise the Stock Option if the Company terminates the Merger Agreement
for the reasons described in clauses (c)(i)(A) and (c)(i)(B) under "The Merger
Agreement -- Termination" above. The Stock Option may be exercised during the
period (the "Exercise Period") commencing on the date the Offer is terminated or
expires, as described above, and ending on the date which is three months
following the date which any Superior Proposal expires or is withdrawn or
terminated without the purchase of any Shares.

     The closing of the sale of the Shares subject to the Stock Option (the
"Stock Option Closing") is conditioned upon (i) the waiting periods under the
HSR Act expiring or terminating and (ii) there being no order of a court of
competent jurisdiction restricting or prohibiting the exercise of the Stock
Option or the delivery of the Shares thereunder.

     Notwithstanding anything in the Stock Option Agreement to the contrary, and
notwithstanding that the Stock Option has otherwise become exercisable, if at
any time during the Exercise Period a tender offer pursuant to any Superior
Proposal (the "Superior Offer") is commenced, then, subject to the terms and
conditions of this provision, on the last day of the offer period of the
Superior Offer, such Stockholders will tender their Shares in the Superior
Offer. Concurrent therewith, if Optionee's tender offer is continuing at such
time, the Stockholders' Shares will be released from Optionee's tender offer.
Except in certain circumstances, Optionee's right to exercise the Stock Option
will be suspended for so long as the Superior Offer shall not have expired or
been terminated or withdrawn and, subject to the terms of this provision, such
right will terminate simultaneously with the consummation of the Superior Offer
and receipt by the Stockholders of the consideration therefor. Notwithstanding
the foregoing, Optionee may elect, by written notice to the Stockholders at any
time prior to the tender of such Shares into the Superior Offer by the
Stockholders, to require the Stockholders, on a pro rata basis, to retain Shares
in an amount, as determined by Optionee, up to 25% of the then outstanding
shares of Common Stock on a fully diluted basis (the "Minority Percentage"),
whereupon the Stockholders will not tender such amount of Shares in the Superior
Offer and Optionee's right to exercise the Stock Option as to such Shares will
continue without limitation.

     The Stock Option Agreement also provides that in the event that the
Superior Offer is consummated, as to Shares tendered by the Stockholders in
accordance with the foregoing paragraph, each Stockholder will deliver to the
Optionee that portion of the consideration received by such Stockholder which is
equal to the Incremental Value (as defined below) multiplied by the number of
Shares tendered by such Stockholder in connection with such Superior Proposal.
The Incremental Value will be determined as follows: if the consideration
payable pursuant to the Superior Offer is all cash, the Incremental Value will
equal the amount by which the offer price in such Superior Proposal exceeds the
Offer Price. If the consideration payable consists of cash and securities or
only securities, the Incremental Value will equal the amount by which (x) the
sum of the cash, if any, plus the value of the securities received in the
Superior Proposal (the amount of such cash and the value of such securities
being determined on a per share basis) exceeds (y) the Offer Price. The value of
any publicly-traded securities issued to the Stockholders upon consummation of
the Superior Proposal will be determined by reference to the closing price of
such securities on the date of consummation of the Superior Proposal. The value
of any securities which have not previously been publicly traded ("Newly
Registered Securities") will be determined by reference to the average closing
price of such securities over the twenty (20) trading days following
consummation of the Superior Proposal. Each Stockholder will deliver to the
Optionee the Incremental Value for each Share held by such Stockholder
immediately upon receipt if the consideration is cash or cash and
publicly-traded securities or, if the consideration includes Newly Registered
Securities, upon the later of receipt of the consideration or the date on which
the value of the securities is determined. The Incremental Value will be payable
to Optionee in cash and securities in the same proportion as the cash and
securities payable to the Stockholders. If Optionee has required the
Stockholders to retain the Minority Percentage, the Optionee will exercise the
Stock Option with respect to the Minority Percentage promptly upon the
consummation of the Superior Offer.

     The Stock Option Agreement provides that in the event that the Superior
Proposal is structured as a merger which is not preceded by a tender offer, the
Stockholders will be permitted to vote such Stockholders' Shares in favor of
such merger; provided, however, that Optionee may elect to require the
Stockholders to abstain from voting in favor of the merger with respect to the
Minority Percentage. Except in certain circumstances, Optionee's right to
exercise the Stock Option will be suspended so long as the Superior Proposal
described in this provision shall not have expired or been terminated or
withdrawn and, subject to the terms of this provision, such right will terminate
simultaneously with the consummation of such Superior Proposal and receipt by
the Stockholders of the consideration therefor. In the event that such Superior
Offer is consummated, each Stockholder will pay to Optionee, at the time
determined in


                                       10

<PAGE>

accordance with the similar provisions described above, the Incremental Value
received by such Stockholder for each of such Stockholder's Shares.

     The Stock Option Agreement provides that, in the event that (pursuant to
the Stock Option) Optionee purchases an amount of the Stockholders' Shares
greater than the Minority Percentage, then as promptly as practicable (and in
any event within five (5) business days thereafter), Newco will, and Parent will
cause Newco to, make a tender offer to the stockholders of the Company for the
remaining shares of Company Common Stock (the consummation of which will be
subject only to the conditions that no court, arbitrator or governmental body,
agency or official shall have issued any order, decree or ruling and there shall
not be any statute, rule or regulation, enjoining or prohibiting the
consummation of such tender offer) pursuant to which the stockholders of the
Company (other than the Company, any direct or indirect subsidiary of the
Company or Parent or Newco) will be entitled to receive an amount of cash
consideration per share of Common Stock equal to the Offer Price, and will take
such actions as may be necessary or appropriate to effectuate, and purchase
shares of Common Stock pursuant to, such tender offer at the earliest
practicable time.

     The Stock Option Agreement will terminate and be of no further force and
effect if, as a result of the failure of any conditions to such Stock Option
Closing to be satisfied, the Stock Option Closing shall not have occurred within
one (1) year following delivery of an exercise notice, subject to a 30-day
extension under certain circumstances.

     Pursuant to the Stock Option Agreement, the Stockholders have agreed to
vote all Shares held by such Stockholders (i) in favor of the Merger, the Merger
Agreement and the transactions contemplated thereby and (ii) against any action
or agreement that would result in a material breach of a covenant,
representation or warranty or other obligation of the Company under the Merger
Agreement and (iii) against any action or agreement that would materially
impede, interfere with or attempt to discourage the Offer or the Merger.

     Pursuant to the Stock Option Agreement, each Stockholder has also agreed
that if the Merger Agreement is terminated by the Company prior to the purchase
of Shares in the Offer because the Company Board has (i) entered into or shall
have publicly announced its intention to enter into an Alternative Proposal that
it determines is a Superior Proposal or (ii) withdrawn, modified or changed in a
manner adverse to Parent or Newco its approval of the Offer, the Merger
Agreement or the Merger, then such Stockholder will, (A) participate in all
meetings of stockholders, (B) not vote any such Shares in favor of actions
requiring stockholder approval described in Section 5 of the Merger Agreement
and (C) use its reasonable efforts as a stockholder to prevent actions
prohibited by Section 5 of the Merger Agreement.

     Each of the Stockholders has agreed that during the Exercise Period in the
event that such Stockholder has breached the voting agreements described above,
such Stockholder will be deemed to have granted Parent proxies to vote his or
her Shares, except that Parent will not have the right to vote to reduce the
Offer Price or the Merger Consideration or to amend or modify the Merger
Agreement or reduce the rights or benefits of the Company or any stockholders of
the Company under the Offer or the Merger Agreement or reduce the obligations of
Parent or Newco thereunder. The Stock Option Agreement provides that such
proxies terminate if (x) the Offer expires or terminates without any Shares
being purchased thereunder in violation of the Offer or the Merger Agreement or
(y) Parent or Newco is in violation of the Stock Option Agreement.

     The Stock Option Agreement contains the agreement of Mark L. Nelson to
indemnify Parent, Newco and their affiliates against losses or damages
("Damages") incurred by Parent, Newco or their affiliates arising out of any
breach of any representation or warranty of the Company, or nonfulfillment of
any covenant or agreement by the Company, in each case contained in or made
pursuant to the Merger Agreement. Mr. Nelson is not required to indemnify any
indemnified party until Damages equal or exceed $5,000,000. Thereafter, Mr.
Nelson's indemnification obligations will apply to the next $5,000,000 of
Damages, and 50% of the next $20,000,000 of Damages, up to a maximum
indemnification obligation of $15,000,000. Notice of any claim for
indemnification must be delivered by an indemnified party on or prior to the
18-month anniversary of the consummation of the Offer or the Stock Option
closing, as the case may be.

     The Stock Option Agreement provides that except for the Stock Option and
the indemnification provisions contained therein, the Stock Option Agreement
terminates on the date the Merger Agreement terminates.

     The Stock Option Agreement contains certain representations of the
Stockholders and Parent and Offeror. In addition, the Stock Option Agreement
contains the agreements of the Stockholders not to sell any of their Shares
during the term of the Stock Option Agreement, except as contemplated therein.
The Stock Option Agreement also provides that the Stockholders will not directly
or indirectly solicit or initiate any takeover proposal from any person,


                                       11

<PAGE>

or engage in discussions or negotiations relating thereto, except as provided in
the Merger Agreement. The Stock Option Agreement provides that none of these
provisions will limit or restrict in any manner whatsoever any Stockholder's
actions or conduct as a director or representative of the Company.

  Wolters Kluwer Guarantee

     In connection with and pursuant to the Merger Agreement, Wolters Kluwer nv,
a corporation organized under the laws of The Netherlands ("Wolters Kluwer") and
the ultimate parent of Parent and Newco, has agreed to unconditionally guarantee
the payment obligations of Parent and Newco under the Merger Agreement pursuant
to a letter agreement between Wolters Kluwer and the Company dated September 29,
1998, a copy of which is filed herewith as Exhibit 4.

ITEM 4. THE SOLICITATION OR RECOMMENDATION.

     (a) RECOMMENDATION OF THE COMPANY BOARD

     The Company Board has unanimously approved the Merger Agreement, the Offer
and the Merger, and has determined that the Offer and the Merger are fair to and
in the best interests of the Company's stockholders, and unanimously recommends
that the Company's stockholders accept the Offer and tender their Shares in the
Offer.

     A letter to the Company's stockholders communicating the Company Board's
recommendation and a press release announcing the execution of the Merger
Agreement are filed herewith as Exhibits 5 and 6, respectively, and are
incorporated herein by reference.

     (b) BACKGROUND; REASONS FOR THE COMPANY BOARD'S RECOMMENDATION

     Over the past decade, the scientific, technical and medical publishing
("STM") market (the market in which the Company operates) has been marked by
continuing consolidation, increasing Internet-based distribution by publishing
companies who license their materials to the Company, continuing constraints on
customer subscription budgets and increasing pressure by information suppliers
on licensees' (including the Company) operating margins. Given the state of the
market, the Company, from time to time, considered possible business
collaborations, joint ventures and other possible arrangements with publishing
companies in the STM market. The Company also attempted (unsuccessfully) to
acquire or make significant investments in companies in its markets in an effort
to expand its customer base and improve its geographic coverage, including an
attempt in 1997 to make what would have been a significant acquisition.

     As a result of developments relating to the STM markets, the Company's
management evaluated a number of strategic options. On March 26, 1998, the
Company's management reviewed its strategic assessment of the Company with the
Company Board. The Company Board instructed management to negotiate with
investment banking firms that might be helpful to the Company in defining and
pursuing its goals. The Company's management reviewed a range of strategic
options to enhance stockholder value at several meetings with Goldman, Sachs &
Co. ("Goldman Sachs") in March 1998. The result of this review was the decision
by management to recommend that the Company initiate a process to explore the
sale of the entire equity interest in the Company through a controlled auction
process (the "Auction Process"). On April 1, 1998, the Company retained Goldman
Sachs to assist the Company as its financial advisor in connection with the
possible sale of all or a portion of the Company. Shortly thereafter, Goldman
Sachs (in collaboration with Company management) identified a list of leading
candidates that might be expected to have an interest in potentially purchasing
the Company. With management's consent, Goldman Sachs then began making calls to
the approved list of potential candidates.

     On April 23, 1998, Goldman Sachs made a presentation to the Company Board.
Goldman Sachs identified and reviewed a list of leading candidates, as approved
by management, that might be expected to have an interest in potentially
purchasing the Company, updated the Company Board as to what calls had already
been initiated by Goldman Sachs (with management's approval), outlined a
description of the Auction Process and presented a preliminary timetable for a
potential transaction. The Company Board approved the Auction Process at its
April 23, 1998 meeting.

     Throughout April and May 1998, the Company, through Goldman Sachs and the
Company's legal counsel, negotiated and executed confidentiality agreements with
parties that expressed an interest in participating in the Auction Process. The
Company entered into confidentiality agreements with five parties, including
with Parent on May 11, 1998.


                                       12

<PAGE>

     After a potential purchaser executed a confidentiality agreement, it was
provided with a "Confidential Information Memorandum" prepared by Goldman Sachs
for use in evaluating a possible transaction with the Company. The Confidential
Information Memorandum included information concerning the history of the
Company, a business overview and financial information. Parties receiving the
Confidential Information Memorandum were instructed to submit a preliminary
indication of interest to Goldman Sachs by June 30, 1998. The preliminary
indication of interest was to include, among other things, a non-binding
indication of the amount and form of consideration the submitting party would be
prepared to pay for the entire common equity of the Company, and the source of
financing of the potential transaction and any contingencies thereto.

     At various times throughout early June 1998, each of the five parties
receiving a Confidential Information Memorandum on the Company was invited to
presentations by the management of the Company. Three of these five parties
accepted and met with management of the Company during the period of June 11,
1998 through June 16, 1998.

     On June 30, 1998, Goldman Sachs received, in writing, one preliminary
indication of interest. A second indication of interest, for a minority
strategic investment in the Company, was expressed to Goldman Sachs orally and
subsequently made in writing on July 8, 1998. After consulting with Goldman
Sachs, the Company's management agreed to continue in the Auction Process with
the two parties submitting preliminary acquisition proposals.

     On July 8, 1998, Goldman Sachs sent to the parties selected to continue in
the Auction Process a letter inviting a final proposal and outlining the
guidelines and further procedures for the Auction Process. The parties were also
provided a form of a proposed purchase agreement. The parties were invited to
submit a firm written offer to acquire the Company (a "Proposal") by July 22,
1998. The July 8, 1998 letter identified the factors the Company would use in
evaluating Proposals and instructed the parties to include in the Proposal the
specific amount of consideration offered per share. Each party was asked to mark
changes in the Company's proposed form of purchase agreement and to include in
the Proposal a statement that such party would be prepared to execute the
agreement (with any proposed modifications) in the form submitted. Pursuant to
this letter, submission of a Proposal constituted an agreement to be bound by
the terms set forth therein. The parties were invited to conduct a due diligence
review of the Company, which included follow-up discussions with the management
of the Company and a detailed review of Company documents.

     On July 10, 1998, the Company, Parent and their respective financial
advisors met to discuss a possible minority investment in the Company. On July
21, 1998, the Company was informed by another potential purchaser that it would
not be submitting a Proposal. On July 22, 1998, Parent submitted a non-binding
proposal to acquire a minority position in the Company. On July 23, 1998, the
Company, Goldman Sachs and the Company's legal counsel had several discussions
to evaluate the responses received from the potential purchasers, including the
Proposal submitted by Parent on July 22, 1998 for making a minority strategic
investment in the Company together with an option for the balance of the
Company. After lengthy discussions on July 23, 1998, the Company concluded that
Parent's Proposal required further clarification. A meeting between the parties
was held on July 24, 1998 to review the offer and strategic opportunities
relating to a minority investment transaction. The Company concluded that
Parent's Proposal could potentially be favorable to the Company and its
stockholders, both as to price and other terms, and authorized Goldman Sachs to
begin tentative negotiations with Parent and its financial advisor. On July 28,
1998, the Company Board authorized Goldman Sachs to continue discussions with
Parent with respect to a minority investment in the Company.

     During the period beginning in late July and continuing through the second
week in August, the Company and Parent exchanged a series of term sheets
containing various proposals for a minority investment in the Company by Parent.
Representatives of the Company and Parent met on August 12, 1998, and held
several telephone conversations regarding a possible transaction with Parent.
During this period, the Company, Goldman Sachs and the Company's legal counsel
discussed the merits of Parent's minority investment proposals and the results
of various negotiations with Parent and its financial advisor. Parent's Proposal
consisted of (i) the acquisition of 2,250,000 newly issued Shares of the Company
at $25 per Share, provided that (x) the Company would agree to use at least 90%
of the proceeds from the sale of such Shares to fund a self tender at a price of
no more than $25 per Share (designed to cause Parent's stake in the Company to
equal 25% of the Shares (on a fully diluted basis)) and (y) the Stockholders
would guarantee this result by agreeing to tender sufficient Shares to make up
any shortfall in tenders by the public, (ii) the receipt of an option to acquire
the remaining shares and options owned by each of Mark L. Nelson, Deborah Hull,
Carleen Nelson and Martin Kahn for a number of years and (iii) the imposition of
certain restrictions on the Company's ability to undertake certain actions
without the consent of Parent. The Company ultimately concluded that Parent's
Proposal was not in the best interests of the Company and its stockholders, and 


                                       13

<PAGE>

notified Parent on August 20, 1998 that it no longer desired to pursue a
transaction similar to the one proposed by Parent. In addition to the proposal
for a minority investment, Parent had proposed to the Company on August 20, 1998
the possibility of a "going private" transaction. On August 25, 1998, the
Company submitted a proposal outlining the terms of a possible "going private"
transaction, and over the next two weeks the Company and Parent exchanged term
sheets with respect to a "going private" transaction. On September 11, 1998,
during a telephone meeting of the Company Board, the Company Board authorized
management to continue discussions with Parent and agreed to establish a Special
Committee of independent directors of the Company Board to evaluate the fairness
to the public of the proposed "going private" transaction.

     On September 15 and 16, 1998, Company management met with members of
Parent's Executive Board and senior management regarding certain matters related
to the proposed transaction. On the afternoon of September 16, 1998, Parent made
a new proposal pursuant to which it would purchase all of the issued and
outstanding shares of the Company Common Stock. On September 17, 1998, a
telephone meeting of the Company Board was held authorizing the Company and its
advisors to continue negotiations and asking Goldman Sachs to advise the Board
on the fairness of the transaction with Parent. At the request of Parent, and
after a number of telephone conference calls between advisors to the Company and
Parent, the Company determined to enter into exclusive negotiations with Parent
through their respective financial and legal advisors. On September 18, 1998,
Company Board members were polled by telephone and agreed to the terms for
exclusive negotiations with Parent. One director was unavailable and he
subsequently advised the Company Board that he approved the exclusivity
agreement. An agreement in this regard was signed on September 22, 1998, a copy
of which is filed herewith as Exhibit 8.

     From September 23, 1998 through the evening of September 28, 1998, the
Company's legal counsel and legal counsel for Parent held negotiations
concerning the Merger Agreement and the Stock Option Agreement. In connection
with Parent's proposal to acquire all of the Company Common Stock, Parent
required that Mr. Nelson agree to personally indemnify Parent and its affiliates
against breaches of representations and agreements made in the Merger Agreement
by the Company in favor of Parent. After a significant amount of negotiation,
Mr. Nelson agreed to provide the indemnification described under "Item 3.
Identity and Background--Arrangement with Parent, Newco or Their
Affiliates--Stock Option and Tender Agreement" above. In addition, following
negotiations, Parent agreed to the Company's request that the grant of the Stock
Option under the Stock Option Agreement be subject to a "fiduciary out"
provision tied to the "fiduciary out" provision for a Superior Proposal in the
Merger Agreement. As consideration for this provision, the Stockholders agreed
to pay to Parent any incremental amount above the Offer Price payable to them in
respect of a transaction arising out of a Superior Proposal.

     On September 29, 1998, the Company Board met to consider the Merger
Agreement and transact other business. Goldman Sachs made a presentation to the
Company Board outlining the results of the Auction Process and reviewing the
details of the Parent Proposal. Counsel to the Company reviewed the terms of the
Offer, Merger Agreement and Stock Option Agreement. A lengthy discussion
followed each of the presentations. Thereafter, the Company Board unanimously
approved the Offer, the Merger, the Merger Agreement and the other transactions
contemplated thereby.

     In approving the Offer, the Merger, the Merger Agreement and the other
transactions contemplated thereby and recommending that all holders of Shares
accept the Offer and tender their Shares pursuant to the Offer, the Company
Board considered a number of factors including:

          1. The presentations and views expressed by management of the Company
     (at the meeting of the Company Board held on September 29, 1998, and at
     previous meetings of the Company Board) regarding, among other things: (a)
     the business, operating results, financial condition, financing capacity,
     strategic objectives, and prospects of the Company, as well as the risks
     involved in achieving those prospects and objectives in current industry,
     economic and market conditions; (b) the possible alternatives to the Merger
     available to the Company including raising additional capital and possible
     acquisitions; (c) the fact that in view of the discussions held with
     various parties, as well as the Auction Process, the management of the
     Company believed it was unlikely that any other party would propose an
     acquisition or strategic business combination that would be more favorable
     to the Company and its stockholders than the Offer and the Merger; and (d)
     the recommendation of the Offer and the Merger by the management of the
     Company.

          2. The presentation of Goldman Sachs at the meeting of the Company
     Board held on September 29, 1998, and the opinion of Goldman Sachs,
     expressed orally at the September 29, 1998 meeting (and subsequently
     confirmed in writing), to the effect that, as of September 29, 1998, the
     $24.59 in cash to be received by the Company's stockholders in the Offer
     and the Merger is fair from a financial point of view to the Company's







                                       14

<PAGE>

     stockholders. The full text of the written opinion of Goldman Sachs, dated
     September 29, 1998, which sets forth assumptions made, matters considered
     and limitations on the review undertaken in connection with the opinion, is
     attached hereto as Annex A and is incorporated herein by reference. The
     opinion of Goldman Sachs referred to herein does not constitute a
     recommendation as to whether or not any holder of Shares should tender such
     Shares in connection with the Offer. All stockholders are urged to, and
     should, read the opinion of Goldman Sachs carefully in its entirety.

          3. The historical market prices and the recent limited trading
     activity of the Shares, including the fact that the Offer Price represents
     a premium of approximately 49% over the closing price of the Shares on the
     Nasdaq National Market at April 1, 1998, the time when the Company began
     exploring possible transactions.

          4. The arms-length negotiations between the Company and Parent leading
     to the belief of the Company Board that $24.59 per Share represented the
     highest price per Share that could be negotiated with Parent.

          5. That the Offer and the Merger provide for a prompt cash tender
     offer for all Shares to be followed by a merger for the same consideration,
     thereby enabling the Company's stockholders to obtain the benefits of the
     transaction in exchange for their Shares at the earliest possible time.

          6. The business reputation and capabilities of Parent and its
     management, and Parent's financial strength, including its ability to fund
     the Offer.

          7. The terms, conditions and possible consequences to the Company of
     the Stock Option Agreement, including the grant of the Stock Option and the
     possible adverse impact of the Option on the willingness of others to make
     alternative proposals to acquire the Company prior to the closing of the
     Offer.

     The foregoing discussion of information and factors considered and given
weight by the Company Board is not intended to be exhaustive. In view of the
variety of factors considered in connection with its evaluation of the Offer and
the Merger, the Company Board did not find it practicable to, and did not,
quantify or otherwise assign relative weights to the specific factors considered
in reaching its determinations and recommendations. In addition, individual
members of the Company Board may have given different weights to different
factors.

ITEM 5. PERSONS RETAINED, EMPLOYED OR TO BE COMPENSATED.

     Pursuant to the terms of a letter agreement dated April 1, 1998 (the
"Engagement Letter"), the Company retained Goldman Sachs to act as its financial
advisor in connection with the possible sale of all or a portion of the Company,
and to render a fairness opinion to the Company in connection with the sale of
more than 50% of the Company Common Stock. Pursuant to the terms of the
Engagement Letter, the Company has agreed to pay Goldman Sachs upon consummation
of the tender offer a transaction fee. Based upon the aggregate consideration to
be received by the Company's stockholders and option holders in the Offer and
the Merger (approximately $192 million), the fee payable and expenses
reimbursable to Goldman Sachs total approximately $4.6 million, of which Mark L.
Nelson has agreed to pay $303,320. The Company has agreed to reimburse Goldman
Sachs for its reasonable out-of-pocket expenses, including attorney's fees, and
to indemnify Goldman Sachs and certain related persons against certain
liabilities, including certain liabilities under the federal securities laws.

     Except as disclosed herein, neither the Company nor any person acting on
its behalf has employed, retained or compensated any person to make
solicitations or recommendations to the Company's stockholders with respect to
the Offer or the Merger.

ITEM 6. RECENT TRANSACTIONS AND INTENT WITH RESPECT TO SECURITIES.

transactions in the Shares have been effected during the past 60 days by the
Company or, to the best of the Company's knowledge, by any executive officer,
director, affiliate or subsidiary of the Company.

     (b) To the best knowledge of the Company, all of its executive officers,
directors, affiliates and subsidiaries currently intend to tender pursuant to
the Offer all Shares held of record or beneficially owned by them (other than
Shares issuable upon exercise of stock options).

ITEM 7. CERTAIN NEGOTIATIONS AND TRANSACTIONS BY THE SUBJECT COMPANY.

     (a) Except as set forth in this Schedule 14D-9, the Company is not engaged
in any negotiation in response to the Offer which relates to or would result in
(i) an extraordinary transaction, such as a merger or reorganization, involving
the Company or any subsidiary of the Company; (ii) a purchase, sale or transfer
of a material amount of assets by the Company or any subsidiary of the Company;
(iii) a tender offer for or other acquisition of securities by or of the
Company; or (iv) any material change in the present capitalization or dividend
policy of the Company.

in paragraph (a) of this Item 7.

PERSONAL AND CONFIDENTIAL
- -------------------------

September 29, 1998

Board of Directors
Ovid Technologies, Inc.
333 Seventh Avenue
New York, NY 10001



Ladies and Gentlemen:

     You have requested our opinion as to the fairness from a financial point of
view to the holders of the outstanding shares of Common Stock, par value $.01
per share (the "Shares"), of Ovid Technologies, Inc. (the "Company") of the
$24.59 per Share in cash proposed to be paid by Purchaser (as defined below) in
the Tender Offer and the Merger (each as defined below) pursuant to the
Agreement and Plan of Merger, dated as of September 29, 1998, among Wolters
Kluwer U.S. Corporation ("Buyer"), OTI Acquisition Corp., a wholly-owned
subsidiary of Buyer ("Purchaser"), and the Company (the "Agreement"). The
Agreement provides for a tender offer for all of the Shares (the "Tender Offer")
pursuant to which Purchaser will pay $24.59 per Share in cash for each Share
accepted. The Agreement further provides that following completion of the Tender
Offer, Purchaser will be merged with and into the Company (the "Merger") and
each outstanding Share (other than Shares that are owned by the Company as
treasury stock and Shares already owned by Buyer, Purchaser or any other
wholly-owned subsidiary of Buyer) will be converted into the right to receive
$24.59 in cash. In addition to the Agreement, Buyer, Purchaser and certain
stockholders of the Company (the "Stockholders") have entered into a Stock
Option and Tender Agreement, dated as of September 29, 1998 (the "Stock Option
and Tender Agreement"), whereby each Stockholder has agreed, among other things,
(i) to tender in the Tender Offer all of the Shares legally and/or beneficially
owned by such Stockholder (the "Stockholder's Shares") as of the date of the
Stock Option and Tender Agreement or which may thereafter be acquired by such
Stockholder, (ii) to grant to Buyer or Purchaser, as Buyer shall designate, the
option to purchase the Stockholder's Shares in certain circumstances, (iii) to
appoint Buyer as such Stockholder's attorney-in-fact and proxy under certain
circumstances to vote the Stockholder's Shares in accordance with the terms and
conditions of the Stock Option and Tender Agreement, (iv) with respect to
certain questions put to stockholders of the Company for a vote, to vote the
Stockholder's Shares, in each case, in accordance with the terms and conditions
of the Stock Option and Tender Agreement, and (v) to restrict the transfers or
exercises of Company Options (as defined in the Stock Option and Tender
Agreement), if any, held by such Stockholder except as provided therein.

     Goldman, Sachs & Co., as part of its investment banking business, is
continually engaged in the valuation of businesses and their securities in
connection with mergers and acquisitions, negotiated underwritings, competitive
biddings, secondary distributions of listed and unlisted securities, private
placements and valuations for estate, corporate and other purposes. We are
familiar with the Company having acted as its financial advisor in connection
with, and having participated in certain of the negotiations leading to, the
Agreement. Goldman, Sachs & Co. provides a full range of financial advisory and
securities services and, in the course of its normal trading activities, may
from time to time effect transactions and hold securities, including derivative
securities, of the Company or the Buyer or any affiliate of the Buyer for its
own account and for the accounts of customers.


                                       20

<PAGE>

     In connection with this opinion, we have reviewed, among other things, the
Agreement; the Stock Option and Tender Agreement; Annual Reports to Stockholders
and Annual Reports on Form 10-K of the Company for the three years ended
December 31, 1997; certain interim reports to stockholders and Quarterly Reports
on Form 10-Q of the Company; certain other communications from the Company to
its stockholders; and certain internal financial analyses and pro forma
financial projections of the Company prepared by its management. We have also
held discussions with members of the senior management of the Company regarding
the past and current business operations, financial condition and future
prospects of the Company. In addition, we have reviewed the reported price and
trading activity for the Shares, compared certain financial and stock market
information for the Company with similar information for certain other companies
the securities of which are publicly traded, reviewed the financial terms of
certain recent business combinations in the electronic information providers
industry specifically and in other industries generally and performed such other
studies and analyses as we considered appropriate.

     We have relied upon the accuracy and completeness of all of the financial
and other information reviewed by us and have assumed such accuracy and
completeness for purposes of rendering this opinion. In addition, we have not
made an independent evaluation or appraisal of the assets and liabilities of the
Company or any of its subsidiaries and we have not been furnished with any such
evaluation or appraisal. Our advisory services and the opinion expressed herein
are provided for the information and assistance of the Board of Directors of the
Company in connection with its consideration of the Tender Offer and the Merger
and such opinion does not constitute a recommendation as to whether or not any
holder of Shares should tender such Shares in connection with the Tender Offer.

     We have reviewed the provision in the Stock Option and Tender Agreement
regarding Mark L. Nelson's agreement to indemnify and hold harmless Buyer,
Purchaser and their affiliates from and against all assessments, losses,
damages, liabilities, costs and expenses as set forth in Article 9 of the Stock
Option and Tender Agreement. We have disregarded, with your consent, any effect
that such agreement to indemnify may have on the per Share price to be received
by him pursuant to the Agreement.

     Based upon and subject to the foregoing and based upon such other matters
as we consider relevant, it is our opinion that as of the date hereof the $24.59
in cash to be received by the holders of Shares in the Tender Offer and the
Merger is fair from a financial point of view to such holders.


Very truly yours,



/s/ GOLDMAN, SACHS & CO.

1998, by and among Wolters Kluwer U.S. Corporation, a Delaware corporation
("Parent"), OTI Acquisition Corp., a Delaware corporation and a wholly owned

                                    RECITALS

     WHEREAS, the respective Boards of Directors of Parent, Purchaser and the
Company have, subject to the conditions of this Agreement, determined that the
Merger (as defined below) is in the best interests of their respective
stockholders and approved this Agreement and the transactions contemplated
hereby; and

     WHEREAS, Parent, Purchaser and the Company desire to make certain
representations, warranties, covenants and agreements in connection with the
Merger.

     NOW, THEREFORE, in consideration of the foregoing and the mutual
representations, warranties, covenants and agreements set forth herein, and in
consideration of the execution and delivery by Parent, Purchaser and the
Stockholders named therein of a stock option and tender agreement (the "Stock
Option and Tender Agreement"), Parent, Purchaser and the Company hereby agree as
follows:


                                    ARTICLE I

                              THE OFFER AND MERGER

     1.1 The Offer.

          (a) As promptly as practicable (but in no event later than five
business days after the public announcement of the execution hereof), Purchaser
shall commence (within the meaning of Rule 14d-2 under the Securities Exchange
Act of 1934, as amended (the "Exchange Act")) an offer (the "Offer") to purchase
for cash all shares of the issued and outstanding Common Stock, par value $.01
per share (referred to herein as either the "Shares" or "Company Common Stock"),
of the Company, at a price per Share, based upon the representations set forth
in Section 3.2 hereof, of $24.59 net to the seller in cash (such price per
Share, or such higher price per Share as may be paid in the Offer, being
referred to herein as the "Offer Price"), subject to there being validly
tendered and not withdrawn prior to the expiration of the Offer, that number of
Shares which, together with the Shares beneficially owned by Parent or
Purchaser, represent 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 A hereto. Purchaser shall, on the terms and subject to the prior
satisfaction or waiver (except that the Minimum Condition may not be waived) of
the conditions of the Offer, accept for payment and pay for Shares tendered as


<PAGE>

soon as it is legally permitted to do so under applicable law. The obligations
of Purchaser to commence the Offer and to accept for payment and to pay for any
Shares validly tendered on or prior to the expiration of the Offer and not
withdrawn shall be subject only to the Minimum Condition and the other
conditions set forth in Annex A hereto. The Offer shall be made by means of an
offer to purchase (the "Offer to Purchase") containing the terms set forth in
this Agreement, the Minimum Condition and the other conditions set forth in
Annex A hereto. Purchaser expressly reserves the right to amend any of the terms
and conditions of the Offer; provided that Purchaser shall not amend or waive
the Minimum Condition, decrease the Offer Price or decrease the number of Shares
sought, change the form of consideration to be paid pursuant to the Offer,
impose conditions to the Offer in addition to those set forth in Annex A hereto,
or amend any other term or condition of the Offer in any manner adverse to the
holders of the Shares or extend the expiration date of the Offer without the
prior written consent of the Company (such consent to be authorized by the Board
of Directors of the Company or a duly authorized committee thereof).
Notwithstanding the foregoing, Purchaser shall, and Parent agrees to cause
Purchaser to, extend the Offer for a period of ten (10) business days following
the initial expiration date of the Offer, if any conditions to the Offer have
not been satisfied or waived at such date. In addition, following such first
extension of the Offer as provided in the preceding sentence, (i) Purchaser
shall, and Parent agrees to cause Purchaser to, extend the Offer, at any time
prior to the termination of this Agreement, for one or more periods of not more
than ten business days, if at the expiration date of the Offer, as extended, all
conditions to the Offer have not been satisfied or waived, and (ii) the Offer
Price may be increased and the Offer may be extended to the extent required by
law in connection with such increase, in each case without the consent of the
Company. In addition, Purchaser may, without the consent of the Company, extend
the Offer for a period of not more than ten (10) business days beyond the latest
expiration date that would otherwise be permitted under clause (i) or (ii) of
the immediately preceding sentence if there shall not have been tendered and not
withdrawn pursuant to the Offer at least 90% of the outstanding Shares.

          (b) As soon as practicable on the date the Offer is commenced, Parent
and Purchaser shall file with the United States Securities and Exchange
Commission (the "SEC") a Tender Offer Statement on Schedule l4D-l with respect
to the Offer (together with all amendments and supplements thereto and including
the exhibits thereto, the "Schedule 14D-1"). The Schedule 14D-l will include, as
exhibits, the Offer to Purchase and a form of letter of transmittal and summary
advertisement (collectively, together with any amendments and supplements
thereto, the "Offer Documents"). Parent and Purchaser represent that 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
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 further agrees to take all steps
necessary to cause the Offer Documents to be filed with the SEC and to be
disseminated to holders of Shares, in each case as and to the extent required by
applicable federal securities laws. Each of Parent and Purchaser, on the one
hand, and the 


                                       2
<PAGE>

Company, on the other hand, agrees promptly to correct any information provided
by it for use in the Offer Documents if and to the extent that it shall have
become false and misleading in any material respect and each of Parent and
Purchaser further agrees to take all steps necessary to cause the Offer
Documents as so corrected to be filed with the SEC and to be disseminated to
holders of Shares, in each case as and to the extent required by applicable
federal securities laws. The Company and its counsel shall be given a reasonable
opportunity to review and comment on the Schedule 14D-l and the Offer Documents
before they are filed with the SEC. In addition, Parent and Purchaser agree to
provide the Company and its counsel in writing with any comments or other
communications that Parent, Purchaser or their counsel may receive from time to
time from the SEC or its staff with respect to the Offer Documents promptly
after the receipt of such comments or other communications, and shall provide
the Company and its counsel a reasonable opportunity to comment on the proposed
response of Parent and Purchaser to such comments.

     1.2 Company Actions.

          (a) The Company hereby approves of and consents to the Offer and
represents that the Board of Directors of the Company, at a meeting duly called
and held, has (i) unanimously approved this Agreement and the transactions
contemplated hereby, including the Offer and the Merger (collectively, the
"Transactions"), (ii) unanimously determined that as of the date hereof the
Transactions are fair to and in the best interests of the Company's stockholders
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, however, that such recommendation
may be withdrawn, modified or amended if, in the opinion of the Board of
Directors of the Company, after consultation with its legal counsel, such
recommendation would be inconsistent with 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. The Company has been advised
that all of its directors and executive officers intend either to tender their
Shares pursuant to the Offer or to vote their Shares in favor of the Merger.

          (b) As promptly as practicable following the commencement of the
Offer, the Company shall file with the SEC a Solicitation/Recommendation
Statement Schedule 14D-9 (together with all amendments and supplements thereto
and including the exhibits thereto, the "Schedule 14D-9") which shall, subject
to the fiduciary duties of the Company's directors under applicable law and to
the provisions of this Agreement, contain the recommendations referred to in
Section 1.2(a) hereof. The Company represents that the Schedule 14D-9 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 


                                       3
<PAGE>

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 therein, in light of the
circumstances under which they were made, not misleading, except that no
representation is made by the Company with respect to information supplied by
Parent or Purchaser for inclusion in the Schedule 14D-9. The information
supplied by Parent or Purchaser for inclusion in the Schedule 14D-9 shall not,
on the date filed with the SEC and on the date first published, sent or given to
the Company's stockholders, 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 were made, not misleading. 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 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 promptly to correct any
information provided by it for use in the Schedule 14D-9 if and to the extent
that it shall have become false and 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 holders of
the Shares, in each case as and to the extent required by applicable federal
securities laws. Parent and its counsel shall be given a reasonable opportunity
to review and comment on the initial Schedule 14D-9 before it is filed with the
SEC. In addition, the Company agrees to provide Parent, Purchaser and their
counsel in writing with any comments, or other communications that the Company
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, and shall provide Parent, Purchaser and their counsel a
reasonable opportunity to comment on the proposed response of the Company to
such comments.

          (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(s) containing the names and
addresses of the record holders of the Shares as of a recent date, and shall
furnish Parent with such information and assistance as Parent or its agents may
reasonably request in communicating the Offer to the stockholders of the
Company. 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 only 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.

     1.3 Directors.

          (a) Promptly upon the purchase of and payment for Shares by Parent or
any of its Subsidiaries (as defined in Section 8.10) which represent at least a
majority of the outstanding shares of Company Common Stock (on a fully diluted
basis), Parent 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 Parent pursuant to this sentence)
multiplied by the percentage that the aggregate number of Shares beneficially
owned by Purchaser, Parent and any of their affiliates bears to the total number
of shares of Company Common Stock then outstanding. The Company shall take all
action necessary to cause Parent's designees to be elected or appointed to the
Company's Board of Directors and to secure the resignations of such number of
its incumbent directors as is necessary to enable Parent's designees to be so
elected to the Company's Board, and shall cause Parent's designees to be so
elected. At such times, the Company will take all 


                                       4
<PAGE>

action necessary to cause individuals designated by Parent to constitute the
same percentage as such individuals represent on the Company's Board or
Directors of (A) each committee of the Board and (B) each board of directors
(and committee thereof) of each Subsidiary in each case to the extent permitted
by the National Association of Securities Dealers (the "NASD") rules.
Notwithstanding the foregoing, until the Effective Time (as defined in Section
1.5 hereof), the Company shall retain as members of its Board of Directors at
least two (2) directors that are directors of the Company on the date hereof
(the "Company Designees"), and Parent and Purchaser shall not vote their Shares
of Company Common Stock or take any other action inconsistent with this
provision; provided, that subsequent to the purchase of and payment for Shares
pursuant to the Offer, Parent shall always have its designees represent at least
a majority of the entire Board of Directors.

     (b) The Company's obligations under Section 1.3(a) shall be subject to
Section 14(f) of the Exchange Act and Rule 14f-l promulgated thereunder. The
Company shall promptly take all actions required pursuant to such Section 14(f)
and Rule 14f-l 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-l as is necessary to enable Parent's designees to be elected to the
Company's Board of Directors. Parent or Purchaser will supply the Company any
information with respect to either of them and their nominees, officers,
directors and affiliates required by such Section 14(f) and Rule 14f-l.

     (c) From and after the time, if any, that Parent's designees constitute a
majority of the Company's Board of Directors and prior to the Effective Time,
any amendment of this Agreement, any termination of this Agreement by the
Company, any extension of time for performance of any of the obligations of
Parent or Purchaser hereunder, any waiver of any condition or any of the
Company's rights hereunder, any other action by the Company hereunder or any
action that would adversely affect the rights of the stockholders of the Company
or the holders of Options (as defined in Section 2.1(d)) with respect to the
transactions contemplated hereby may be effected only by the action of a
majority of the Company Designees then in office, which action shall be deemed
to constitute the action of the full Board of Directors; provided, that if the
number of Company Designees shall be reduced below two for any reason
whatsoever, any remaining Company Designee shall be entitled to designate a
person to fill such vacancy who shall be deemed to be a Company Designee for
purposes of this Agreement or, if no Company Designee 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 Company Designees for purposes of this Agreement.

     1.4 The Merger. Subject to the terms and conditions of this Agreement, at
the Effective Time, the Company and Purchaser shall consummate a merger (the
"Merger") pursuant to which (a) Purchaser shall be merged with and into the
Company and the separate corporate existence of Purchaser shall thereupon cease,
(b) the Company shall be the successor or surviving corporation in the Merger
and shall continue to be governed by the laws of the State of Delaware and (c)
the separate corporate existence of the Company with all its rights, privileges,
immunities, powers and franchises shall continue immediately after the Merger.
The corporation surviving the Merger is sometimes hereinafter referred to as the
"Surviving Corporation." The

Merger shall have the effects set forth in the General Corporation Law of the
State of Delaware (the "DGCL").

     1.5 Effective Time. Parent, Purchaser and the Company will cause a
Certificate of Merger, or if applicable, a Certificate of Ownership and Merger

Closing (as defined in Section 1.6) (or on such other date as Parent and the
Company may agree) with the Secretary of State of the State of Delaware as
provided in the DGCL. The Merger shall become effective at the time at which the
Certificate of Merger has been duly filed with the Secretary of State of the
State of Delaware or at such time as is agreed upon by the parties and specified
in the Certificate of Merger, and such time is hereinafter referred to as the
"Effective Time."

     1.6 Closing. The closing of the Merger (the "Closing") shall take place (a)
at the offices of Fulbright & Jaworski L.L.P., 666 Fifth Avenue, New York, New
York 10103 as soon as practicable following the satisfaction or waiver of all of
the conditions set forth in Article VI hereof or (b) at such other place, time
and date as Parent and the Company may agree.

     1.7 Certificate of Incorporation of the Surviving Corporation. The
Certificate of Incorporation of the Company, as in effect immediately prior to
the Effective Time, shall be the Certificate of Incorporation of the Surviving
Corporation until thereafter amended as provided by law and such Certificate of
Incorporation.

     1.8 By-Laws of the Surviving Corporation. The By-Laws of Purchaser, as in
effect immediately prior to the Effective Time, shall be the By-Laws of the
Surviving Corporation until thereafter amended as provided by law, the
Certificate of Incorporation of the Surviving Corporation and such By-Laws.

     1.9 Directors and Officers of the Surviving Corporation. The directors and
officers of Purchaser at the Effective Time shall, from and after the Effective
Time, be the initial directors and officers, respectively, of the Surviving
Corporation until their successors have been duly elected or appointed and
qualified or until their earlier death, resignation or removal in accordance
with the Surviving Corporation's Certificate of Incorporation and By-Laws.

     1.10 Stockholders' Meeting.

          (a) If required by applicable law in order to consummate the Merger,
the Company, acting through its Board of Directors, shall, in accordance with
applicable law;

               (i) duly call, give notice of, convene and hold a special meeting
          of its stockholders (the "Special Meeting") as soon as practicable
          following the acceptance for payment and purchase of Shares by
          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
          information statement relating to the Merger and this Agreement and
          shall (x) obtain and furnish the

<PAGE>


          information required to be included by the SEC in the Proxy Statement
          (as hereinafter defined) and, after consultation with Parent, to
          respond promptly to any comments made by the SEC with respect to the
          preliminary proxy or information statement and cause a definitive
          proxy or information statement (the "Proxy Statement") to be mailed to
          its stockholders and (y) obtain the necessary approvals of the Merger
          and this Agreement by its stockholders; and

               (iii) subject to the fiduciary obligations of the Board under
          applicable law as determined by the Board after consultation with its
          legal counsel, include in the Proxy Statement the recommendation of
          the board that the stockholders of the Company vote in favor of the
          approval of the Merger and the adoption of this Agreement.

          (b) Parent agrees that it will provide the Company with the
information concerning Parent and Purchaser required to be included in the Proxy
Statement and will vote, or cause to be voted, all of the Shares then owned by
it, Purchaser or any of its other Subsidiaries and affiliates in favor of the
approval of the Merger and the adoption of this Agreement.

          (c) If at any time prior to the Effective Time any event with respect
to the Company or any of its Subsidiaries should occur which is required to be
described in a supplement to the Proxy Statement, such event shall be so
described, and such supplement shall be promptly filed with the SEC and, as
required by law, disseminated to the stockholders of the Company. With respect
to the information relating to the Company, the Proxy Statement will comply as
to form and substance in all material respects with the requirements of the
Exchange Act.

     1.11 Merger Without Meeting of Stockholders. Notwithstanding Section 1.10
hereof, in the event that Parent, Purchaser or any other Subsidiary of Parent
shall acquire at least 90% of the Shares, pursuant to the Offer or otherwise,
the parties hereto agree to take all necessary and appropriate action to cause
the Merger to become effective as soon as practicable after such acquisition,
without a meeting of stockholders of the Company, in accordance with Section 253
of the DGCL.


                                   ARTICLE II

                            CONVERSION OF SECURITIES

     2.1 Conversion of Capital Stock. As of the Effective Time, by virtue of the
Merger and without any action on the part of the holders of any shares of
Company Common Stock or common stock, par value $.01 per share, of Purchaser
("Purchaser Common Stock"):

          (a) Purchaser Common Stock. Each issued and outstanding share of
Purchaser Common Stock shall be converted into and become one fully paid and
nonassessable share of common stock of the Surviving Corporation with the same
rights, powers and privileges 


                                       7
<PAGE>


as the shares so converted and shall constitute the only outstanding shares of
capital stock of the Surviving Corporation.

          (b) Cancellation of Treasury Stock and Parent-Owned Stock. All shares
of Company Common Stock that are owned by the Company as treasury stock and any
shares of Company Common Stock owned by Parent, Purchaser or any other wholly
owned Subsidiary of Parent shall be cancelled and retired and shall cease to
exist and no consideration shall be delivered in exchange therefor.

          (c) Exchange of Shares. Each share of Company Common Stock issued and
outstanding (other than Shares to be cancelled in accordance with Section 2.1(b)
hereof and other than Dissenting Shares (as defined in Section 2.2 below)),
shall be converted into the right to receive, in the manner provided in Section
2.3, the Offer Price, payable to the holder thereof, without interest (the
"Merger Consideration"). All such shares of Company Common Stock, when so
converted, shall no longer be outstanding and shall automatically be cancelled
and retired and shall cease to exist, and each holder of a certificate
representing any such shares shall cease to have any rights with respect
thereto, except the right to receive the Merger Consideration therefor upon the
surrender of such certificate in accordance with Section 2.3.

          (d) Stock Options. As of the Effective Time, each outstanding stock
option (an "Option" and, collectively, the "Options") granted under the Ovid
Technologies, Inc. Stock Plan, effective July 1, 1990, and the Ovid
Technologies, Inc. 1993 Stock Plan, effective October 4, 1993 (collectively, the
"Option Plans"), whether or not then vested or exercisable, shall be converted
into the right to receive from the Company an amount of cash equal to the
product of (i) the number of shares of Company Common Stock subject to the
Option and (ii) the excess, if any, of the Merger Consideration over the
exercise price per share of Company Common Stock of such option (the "Option
Consideration"). Prior to the Effective Time, the Company shall take all steps
necessary to give written notice to each holder of an Option that (i) all
Options shall be canceled effective as of the Effective Time and (ii) upon the
execution and delivery to the Company by such holder of an instrument
acknowledging cancellation of all Options held by such holder effective as of
the Effective Time ("Cancellation Instrument"), the Company shall pay such
holder, promptly following the Effective Time, the Option Consideration for all
Options held by such holder. The Board or any committee thereof responsible for
the administration of the Option Plans shall take any and all action necessary
to effectuate the matters described in this Section 2.1(d) on or before the
Effective Time. Section 3.2 sets forth the number of shares of Company Common
Stock reserved for issuance upon exercise of outstanding Options. Any amounts
payable pursuant to this Section 2.1(d) shall be subject to any required
withholding of taxes and shall be paid without interest. Parent agrees to
provide the Company with sufficient funds to permit the Company to satisfy its
obligations under this Section 2.1(d).

     2.2 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 DGCL, if such Section 262 provides for 


                                       8
<PAGE>


appraisal rights for such Shares in the Merger ("Dissenting Shares"), shall not
be converted into the right to receive the Merger Consideration as provided in
Section 2.1(c), unless and until such holder fails to perfect or withdraws or
otherwise loses his right to appraisal and payment under the DGCL. 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 Merger
Consideration, 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.

     2.3 Exchange of Certificates.

          (a) Paying Agent. Parent shall designate a bank or trust company
reasonably acceptable to the Company to act as agent for the holders of shares
of Company Common Stock in connection with the Merger (the "Paying Agent") to
receive the funds to which holders of shares of Company Common Stock shall
become entitled pursuant to Section 2.1(c) hereof. Parent shall take all steps
necessary to deposit or cause to be deposited with the Paying Agent such funds
as needed for timely payment hereunder in accordance with this Article II. Such
funds shall be invested by the Paying Agent as directed by Parent or the
Surviving Corporation. Parent shall pay all charges and expenses of the Paying
Agent.

          (b) Exchange Procedures. As soon as reasonably practicable after the
Effective Time but in no event more than three (3) business days thereafter, the
Paying Agent shall mail to each holder of record of a certificate or
certificates, which immediately prior to the Effective Time represented
outstanding shares of Company Common Stock (the "Certificates"), whose shares
were converted pursuant to Section 2.1 hereof into the right to receive the
Merger Consideration (i) a letter of transmittal (which shall specify that
delivery shall be effected, and risk of loss and title to the Certificates shall
pass, only upon delivery of the Certificates to the Paying Agent and shall be in
such form and have such other provisions as Parent and the Company may
reasonably specify) and (ii) instructions for use in effecting the surrender of
the Certificates in exchange for payment of the Merger Consideration. Upon
surrender of a Certificate for cancellation to the Paying Agent or to such other
agent or agents as may be appointed by Parent, together with such letter of
transmittal, duly executed, the Paying Agent shall promptly pay the person
entitled thereto the Merger Consideration for each share of Company Common Stock
formerly represented by such Certificate and the Certificate so surrendered
shall forthwith be cancelled. If payment of the Merger Consideration is to be
made to a person other than the person in whose name the surrendered Certificate
is registered, it shall be a condition of payment that the Certificate so
surrendered shall be properly endorsed or shall be otherwise in proper form for
transfer and that the person requesting such payment shall have paid any
transfer and 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 have established to the satisfaction of the Surviving
Corporation that such tax either has been paid or is not applicable. Until
surrendered 


                                       9
<PAGE>


as contemplated by this Section 2.3, each Certificate shall be deemed at any
time after the Effective Time to represent only the right to receive the Merger
Consideration in cash as contemplated by this Section 2.3.

          (c) Transfer Books; No Further Ownership Rights in Company Common
Stock. At the Effective Time, the stock transfer books of the Company shall be
closed and thereafter there shall be no further registration of transfers of
shares of Company Common Stock on the records of the Company. From and after the
Effective Time, the holders of Certificates evidencing ownership of shares of
Company Common Stock outstanding immediately prior to the Effective Time shall

corporation in each jurisdiction where the properties owned, leased or operated,
or the business conducted, by it require such qualification, except where the
failure to so qualify or be in good standing would not have a Company Material
Adverse Effect (as defined in Section 8.10). Each of the Company and its
Subsidiaries has all requisite corporate power and authority to own, lease and
operate its properties and to carry on its business as it is now being
conducted, except where the failure to have such power and authority would not

comparable governing instruments) of each of its Subsidiaries, each as in effect
as of the date hereof.

or any securities or rights convertible into, exchangeable for, or evidencing
the right to subscribe for, any shares of capital stock of the Company or any of

breach of any provision of the respective certificate of incorporation,
respective By-Laws or comparable governing instruments of the Company or any of

Material Adverse Effect The conduct of the business of the Company and its
Subsidiaries is in conformity with all federal, state and local governmental and
regulatory requirements applicable to its business and operations, except where

result in a Company Material Adverse Effect. The Company and its Subsidiaries
have all permits, licenses and franchises from governmental agencies required to
conduct their businesses as now being conducted, except for such permits,
licenses and franchises the absence of which would not, in the aggregate,
reasonably be expected to result in a Company Material Adverse Effect.

continued with, the Company. Notwithstanding the foregoing, nothing in this
Section 5.2 shall require the Board of Directors of the Company on behalf of the
Company to act, or refrain from acting with respect to unsolicited Alternative

position required by Rule 14e-2(a) under the Exchange Act.

necessary, proper or advisable to consummate and make effective as promptly as
practicable the transactions contemplated by this Agreement and (iv) use all

consents and approvals (including but not limited to such filings, consents,
approvals, orders, registrations and declarations as may be required under the
laws of any foreign country in which the Company or any of its Subsidiaries or
Parent or any of its Subsidiaries conducts any business or owns any assets) and
to lift any injunction or other legal bar to the Merger (and, in such case, to

warrants to the Company that Parent's affiliates have full power and authority
to effect the transactions contemplated by this Section 5.4.

          (b) Notwithstanding the foregoing, the Company shall not be obligated
to use all reasonable efforts or take any action pursuant to this Section 5.4 if

                                       26
<PAGE>


     5.5 Access to Information. To the extent permitted by applicable law, upon
reasonable notice, the Company shall (and shall cause each of its Subsidiaries
to) afford to the officers, employees, accountants, counsel, financing sources
and other representatives of Parent, access, during normal business hours during
the period prior to the Effective Time, to all its properties, books, contracts,
commitments and records and, during such period, the Company shall (and shall
cause each of its Subsidiaries to) furnish promptly to the Parent (a) a copy of
each report, schedule, registration statement and other document filed or
received by it during such period pursuant to the requirements of federal
securities laws and (b) all other information concerning its business,
properties and personnel as Parent may reasonably request. Parent will hold any
such information which is nonpublic in confidence in accordance with the
provisions of the Confidentiality Agreement between the Company and Parent,
dated as of May 11, 1998 (the "Confidentiality Agreement").

     5.6 Publicity. The initial 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 the
Company, Parent nor any of their respective affiliates shall issue or cause the
publication of any press release or other announcement with respect to the
Merger, this Agreement or the other transactions contemplated hereby without
prior consultation with the other party, except as may be required by law, the
rules and regulations of any national securities exchange or over the counter
market or by any listing agreement with a national securities exchange.

     5.7 Directors' and Officers' Insurance and Indemnification.

          (a) From and after the consummation of the Offer, Parent shall, and
shall cause the Company (or, if after the Effective Time, the Surviving
Corporation) to, indemnify, defend and hold harmless any person who is now, or
has been at any time prior to the date hereof, or who becomes prior to the
Effective Time, an officer or director (the "Company Indemnified Party") of the
Company and its Subsidiaries against all losses, claims, damages, liabilities,
costs and expenses (including attorney's fees and expenses), judgments, fines,
losses, and amounts paid in settlement in connection with any actual or
threatened action, suit, claim, proceeding or investigation (each a "Claim") to
the extent that any such Claim is based on, or arises out of, the fact that such
person is or was a director or officer of the Company or any of its
Subsidiaries, and to the extent that any such Claim pertains to any matter or
fact arising out of any act or omission prior to or at the Effective Time,
regardless of whether such Claim is asserted or claimed prior to, at or after
the Effective Time, to the full extent permitted under applicable law or the
Company's Articles of Incorporation, By-laws or indemnification agreements in
effect at the date hereof identified on Schedule 5.7, or otherwise as permitted
by contracts identified on Schedule 5.7, including provisions relating to
advancement of expenses incurred in the defense of any action or suit. Without
limiting the foregoing, in the event any Company Indemnified Party becomes
involved in any capacity in any Claim, then from and after consummation of the
Offer Parent shall, or shall cause the Company (or the Surviving Corporation if
after the Effective Time) to, periodically advance to such Company Indemnified
Party its legal and other expenses (including the cost of any investigation and
preparation incurred in connection therewith), subject to the provision by such
Company Indemnified Party 


                                       27
<PAGE>


of an undertaking to reimburse the amounts so advanced in the event of a final
non-appealable determination by a court of competent jurisdiction that such
Company Indemnified Party is not entitled thereto.

          (b) Parent and the Company agree that all rights to indemnification
and all limitations on liability existing in favor of a Company Indemnified
Party as provided in the Company's Certificate of Incorporation and By-laws as
in effect as of the date hereof shall survive the Merger and shall continue in
full force and effect, without any amendment thereto, for a period of six years
from the Effective Time to the extent such rights are consistent with the DGCL;
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 disposition of any and all such claims; provided
further, that nothing in this Section 5.7 shall impair any rights or obligations
of any present or former directors or officers of the Company.

          (c) Parent shall cause to be maintained in effect for the Indemnified
Parties (as defined below) for not less than six years after the Effective Time
policies of directors' and officers' liability insurance and fiduciary liability
insurance with respect to matters occurring at or prior to the Effective Time
(including without limitation, the transaction, contemplated by this Agreement)
providing substantially the same coverage and containing terms and conditions
which are no less advantageous, in any material respect, to those currently
maintained by the Company for the benefit of the Company's present or former
directors, officers, employees or agents covered by such insurance policies
prior to the Effective Time (the "Indemnified Parties").

          (d) In the event Parent or Purchaser or any of their successors or
assigns (i) consolidates with or merges into any other person and shall not be
the continuing or surviving corporation or entity of such consolidation or
merger, or (ii) transfers or conveys all or substantially all of its properties
and assets to any person, then, and in each such case, to the extent necessary
to effectuate the purposes of this Section 5.7, proper provision shall be made
so that the successors and assigns of Parent and Purchaser assume the
obligations set forth in this Section 5.7 and none of the actions described in
clauses (i) or (ii) shall be taken until such provision is made.

     5.8 Employees; Continuation of Benefits. (a) Following the Effective Time,
the Surviving Corporation will provide pension, health and welfare benefits
(other than stock option, stock purchase or similar plans) to employees of the
Company and its Subsidiaries who continue their employment after the Effective
Time (each, a "Continuing Employee") on terms which are generally no less
favorable to such Continuing Employee than the benefits being provided to such
Continuing Employee immediately prior to the Effective Time.

          (b) If at any time Parent shall make a determination that any
Continuing Employee is eligible to participate in any of Parent's benefit plans
after the Effective Time, then, for purposes of eligibility and vesting with
respect to any such plans, Parent will cause the Surviving Corporation to
recognize the service of the Continuing Employees through the Effective Time as
if such service had been performed with Parent.

                    CONDITIONS TO CONSUMMATION OF THE MERGER

     6.1 Conditions to Each Party's Obligation to Effect Merger. The respective
obligations of each party to effect the Merger are subject to the satisfaction
at or prior to the Effective Time of the following conditions:

          (a) Stockholder Approval. If approval of the Merger by the
stockholders of the Company is required by applicable law, this Agreement shall
have been duly approved by the stockholders of the Company entitled to vote with
respect thereto in accordance with applicable law and the Certificate of
Incorporation and By-laws of the Company; provided, that Parent and Purchaser
shall vote (or cause to be voted, if applicable) all shares of Company Common
Stock then owned or controlled by them, directly or indirectly, in favor of the
Merger.

          (b) Injunction. There shall not be in effect any statute, rule,
regulation, executive order, decree, ruling or injunction or other order or a
court or governmental or regulatory agency of competent jurisdiction directing
that the transactions contemplated herein not be consummated or otherwise
materially limiting or restricting ownership or the operation of the business of
the Surviving Corporation; provided, however, that, subject to the terms and
provisions herein provided (including but not limited to Section 5.4 of this
Agreement), prior to invoking this condition each party shall use its reasonable
efforts to have any such decree, ruling, injunction or order vacated.

          (c) Governmental Filings and Consents. Subject to the terms and
provisions herein provided (including but not limited to Section 5.4 hereof),
all governmental consents, orders and approvals legally required for the
consummation of the Merger and the transactions contemplated hereby shall have
been obtained and be in effect at the Effective Time, other than those consents,
orders or approvals which would not reasonably be expected to have a Company
Material Adverse Effect or which would prohibit or materially limit or restrict
the consummation of the transactions contemplated herein or the ownership or
operation of the business of the Surviving Corporation, and the waiting periods
under the HSR Act and under antitrust laws of applicable jurisdictions outside
the United States shall have expired or been terminated.


                                   ARTICLE VII

                                   TERMINATION

            7.1 Termination. This Agreement may be terminated and the Merger
contemplated herein may be abandoned at any time prior to the Effective Time,

          (b) By either the Company or Parent:

               (i) if shares of Company Common Stock shall not have been
          purchased pursuant to the Offer on or prior to three (3) months from
          the execution of this Agreement; provided, however, that the passage
          of the period referred to in the foregoing clause shall be tolled
          during (A) the period during which any party shall be subject to a
          non-final order, decree, ruling or action restraining, enjoining or
          otherwise prohibiting the purchase of shares of Company Common Stock
          pursuant to the Offer or the consummation of the Merger, but not later
          than six (6) months from the execution of this Agreement, or (B) any
          additional waiting period under the HSR Act resulting from a second
          request; provided, further, however, that the right to terminate this
          Agreement under this Section 7.1(b) (i) 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 Parent or Purchaser,
          as the case may be, to purchase shares of Company Common Stock
          pursuant to the Offer on or prior to such date; or

               (ii) if any governmental entity of competent jurisdiction in the
          United States or other country in which the Company directly or
          indirectly has material assets or operations shall have issued an
          order, decree or ruling or taken any other action (which order,
          decree, ruling or other action the parties hereto shall use their
          respective reasonable efforts to lift), in each case permanently
          restraining, enjoining or otherwise prohibiting the transactions
          contemplated by this Agreement and such order, decree, ruling or other
          action shall have become final and non-appealable.

          (c) By the Board of Directors of the Company:

               (i) if, prior to the purchase of shares of Company Common Stock
          pursuant to the Offer, (a) the Board of Directors of the Company shall
          have entered into or shall have publicly announced its intention to
          enter into an agreement or an agreement in principle with respect to
          any Alternative Proposal that the Board of Directors determines, in
          good faith after consultation with its financial advisors, is a
          Superior Proposal (as defined in Section 8.10); (b) the Board of
          Directors of the Company shall have withdrawn, or modified or changed
          in a manner adverse to Parent or Purchaser its approval or
          recommendation of the Offer, this Agreement or the Merger or shall
          have recommended a Superior Proposal or shall have executed, or shall
          have announced its intention to enter into, an agreement in principle
          or definitive agreement relating to a Superior Proposal with a person
          or entity other than Parent, Purchaser or their affiliates (or the
          Board of Directors of the Company resolves to do any of the
          foregoing); (c) any person or group (as defined in Section 13(d) (3)
          of the Exchange Act) (other than Parent, Purchaser or any affiliate

          (d) any representation or warranty made by Parent or Purchaser in this
          Agreement shall not have been true and correct in all material
          respects when made, or Parent or Purchaser shall have failed to


                                       30

          obligations under this Agreement, provided that prior to exercising
          such right of termination, the Company shall give prompt written
          notice to Parent of such misrepresentation or breach of warranty or
          failure to observe or perform; provided, further, that the Company
          shall not have such right of termination if the condition resulting in
          such misrepresentation or breach of warranty or failure to observe or
          perform is cured (i) in the event such notice is delivered on or prior
          to the fourth business day prior to the then-scheduled expiration date
          of the Offer, not later than the earlier of (A) such expiration date
          and (B) ten business days following delivery of such notice and (ii)
          in the event such notice is delivered on or after the third business
          day prior to such expiration date, not later than three business days

          shall be extended as necessary at least until the end of such cure
          period); or

               (ii) if Parent or Purchaser shall have terminated the Offer, or
          the Offer shall have expired, without Parent or Purchaser, as the case
          may be, purchasing any shares of Company Common Stock pursuant
          thereto; provided that the Company may not terminate this Agreement
          pursuant to this Section 7.1(c)(ii) if the Company is in material
          breach of this Agreement; or

               (iii) if Parent, Purchaser or any of their affiliates shall have

          Agreement pursuant to this Section 7.1(c)(iii) if the Company is in
          material breach of this Agreement.

          (d) By Parent or Purchaser:

               (i) if, due to an occurrence that if occurring after the
          commencement of the Offer would result in a failure to satisfy any of
          the conditions set forth in Annex A hereto, Parent, Purchaser, or any
          of their affiliates shall have failed to commence the Offer on or
          prior to five business days following the date of the initial public
          announcement of the Offer; provided that Parent may not terminate this
          Agreement pursuant to this Section 7.1(d)(i) if Parent or Purchaser is
          in material breach of this Agreement; or

               (ii) prior to the purchase of shares of Company Common Stock
          pursuant to the Offer, if (a) the Company shall have received any
          Alternative Proposal which the Board of Directors of the Company has
          determined to designate as a Superior Proposal; (b) the Board of
          Directors of the Company shall have withdrawn, or modified or changed
          in a manner adverse to Parent or Purchaser its approval or
          recommendation of the Offer, this Agreement or the Merger or shall
          have recommended an Alternative Proposal or shall have executed, or
          shall have announced its intention to enter into, an agreement in
          principle or definitive agreement relating to an Alternative Proposal
          with a person or entity other than Parent, Purchaser or their
          affiliates (or the Board of Directors 


                                       31
<PAGE>


          of the Company resolves to do any of the foregoing); (c) any person or
          group (as defined in Section 13(d) (3) of the Exchange Act) (other
          than Parent, Purchaser or any affiliate thereof or Mark L. Nelson)
          shall have become, after the date of this Agreement, the beneficial
          owner (as defined in Rule 13d-3 promulgated under the Exchange Act) of
          50% or more of the outstanding Shares, or (d) any representation or
          warranty made by the Company in this Agreement shall not have been
          true and correct in all material respects when made and shall have
          resulted in, or is reasonably likely to result in, a Company Material
          Adverse Effect, or the Company shall have failed to observe or perform
          in any material respect any of its material obligations under this
          Agreement; provided that prior to exercising such right of
          termination, Parent and Purchaser shall give prompt written notice to
          the Company of such misrepresentation or breach of warranty or failure
          to observe or perform; provided, further, that Parent and Purchaser
          shall not have such right of termination if the condition resulting in
          such misrepresentation or breach of warranty or failure to observe or
          perform is cured (i) in the event such notice is delivered on or prior
          to the fourth business day prior to the then-scheduled expiration date
          of the Offer, not later than the earlier of (A) such expiration date
          and (B) ten business days following delivery of such notice and (ii)

          day prior to such expiration date, not later than three business days

          shall be extended as necessary at least until the end of such cure
          period).

Agreement as provided in Section 7.1, written notice thereof shall forthwith be
given to the other party or parties specifying the provision hereof pursuant to
which such termination is made, and this Agreement shall forthwith become null
and void, and there shall be no liability on the part of Parent, Purchaser or

by the Board of Directors of the Company pursuant to Section 7.1(c)(i)(a), (b)
or (c) hereof or by Parent or Purchaser pursuant to Section 7.1(d)(ii)(a), (b)
or (c) hereof, then immediately following such termination the Company shall pay

assigns. Nothing in this Agreement, express or implied, other than the right to
receive the consideration payable in the Merger pursuant to Article II hereof,
is intended to or shall confer upon any other person any rights, benefits or
remedies of any nature whatsoever under or by reason of this Agreement;
provided, however, that the provisions of Sections 5.7 shall inure to the

                             CONDITIONS TO THE OFFER

     The capitalized terms used in this Annex A shall have the meanings ascribed
to them in the Agreement and Plan of Merger to which it is attached, except that

not in limitation of) Purchaser's rights to extend and amend the Offer at any
time in its sole discretion (subject to the provisions of the Merger Agreement),
Purchaser shall not be required to accept for payment or, subject to any
applicable rules and regulations of the SEC, including Rule 14e-l(c) under the

Shares promptly after termination or withdrawal of the Offer), pay for, and may
delay the acceptance for payment of or, subject to the restriction referred to
above, the payment for, any tendered Shares, and may terminate the Offer if (i)
any applicable waiting period under the HSR Act or the antitrust laws of
applicable jurisdictions outside the United States has not expired or terminated
prior to the expiration of the Offer, (ii) the Minimum Condition has not been
satisfied, or (iii) at any time on or after the date hereof, and before the

          (a) there shall be any statute, rule, regulation, judgment, order or
injunction promulgated, entered, enforced, enacted, issued or applicable to the
Offer or the Merger by any governmental entity of competent jurisdiction in the
United States or other country in which the Company directly or indirectly has
material assets or operations which (1) prohibits the consummation of the Offer
or the Merger, (2) as a result of the Offer or the Merger, restrains or
prohibits, or imposes any material limitations on, Parent's or Purchaser's
ownership or operation of all or a material portion of the businesses or assets
of the Company and its Subsidiaries, taken as a whole, or of Parent and its
Subsidiaries, taken as a whole, or compels Parent or any of its Subsidiaries or
affiliates to dispose of or hold separate all or any material portion of the
business or assets of the Company and its Subsidiaries, taken as a whole, or of
Parent and its Subsidiaries, taken as a whole, or requires the Company, Parent
or Purchaser to pay damages that are material in relation to the Company and its

consummation of, the Offer or the Merger, (4) imposes material limitations on
the ability of Purchaser or Parent effectively to exercise full rights of
ownership of the Shares accepted for payment pursuant to the Offer, including,
without limitation, the right to vote the Shares purchased by it on all matters
properly presented to the Company's stockholders, or (5) requires divestiture by
Parent or any of its Subsidiaries or affiliates of any Shares, provided that
Parent shall have used all reasonable efforts to cause any such judgment, order
or injunction to be vacated or lifted;

          (b) there shall be instituted or pending any action, suit, or
proceeding by any governmental entity of competent jurisdiction in the United
States, or any other country in which 



                                      A-1
<PAGE>


the Company directly or indirectly has material assets or operations, that is
reasonably likely, directly or indirectly, to result in any of the consequences
referred to in clauses (1) through (5) of paragraph (a) above; provided, that
Parent shall have used all reasonable efforts to cause any such action, suit or
proceeding to be withdrawn or dismissed;

          (c) there has been since the date hereof any event, occurrence or
development or state of circumstances or facts which has had or would reasonably
be expected to have a Company Material Adverse Effect;

          (d) the representations and warranties of the Company set forth in the
Merger Agreement shall not be true and accurate as of the date of consummation
of the Offer as though made on or as of such date or the Company shall have
breached or failed in any material respect to perform or comply with any
material obligation, agreement or covenant required by the Merger Agreement to
be performed or complied with by it except, (i) those representations and
warranties that address matters only as of a particular date or only with
respect to a specified period of time which need only be true and accurate as of
such date or with respect to such period or (ii) where the failure of such
representations and warranties to be true and accurate, or the breach,
non-performance or non-compliance with such obligations, agreements or
covenants, do not have, individually or in the aggregate, or would not
reasonably be expected to have, individually or in the aggregate, a Company
Material Adverse Effect;

          (e) the Merger Agreement shall have been terminated in accordance with
its terms;

          (f) the Company shall have entered into a definitive agreement or
agreement in principle with any person with respect to an Alternative Proposal;
or

          (g) the Company's Board of Directors shall have withdrawn, or modified
or changed in a manner adverse to Parent or Purchaser (including by amendment of
the Schedule 14D-9) its recommendation of the Offer, the Merger Agreement, or
the Merger, or recommended an Alternative Proposal, or shall have resolved to do
any of the foregoing;

which in the sole judgment of Parent or Purchaser, in any such case, and
regardless of the circumstances giving rise to such condition, makes it
inadvisable to proceed with the Offer and/or with such acceptance for payment or
payments.

     The foregoing conditions are for the sole benefit of Purchaser and Parent
and may be waived by Parent or Purchaser, in whole or in part at any time and
from time to time in the sole discretion of Parent or Purchaser.

Attention:  Mr. Peter van Wel
            President, Wolters Kluwer U.S. Corporation

Dear Mr. van Wel:

In connection with your consideration of a possible transaction with Ovid
Technologies, Inc. (the "Company"), you have requested information concerning
the Company. As a condition to your being furnished such information, you agree
to treat any information (whether written, electronically recorded or oral)
concerning the Company (whether prepared by the Company, its advisors or
otherwise) which is furnished to you by or on behalf of the Company (herein
collectively referred to as the "Evaluation Material") in accordance with the
provisions of this letter and to take or abstain from taking certain other
actions herein set forth. The term "Evaluation Material" shall also be deemed to
include all notes, analyses, compilations, studies, interpretations or other
documents prepared by you or any of your directors, officers, employees, agents
or advisors (including without limitation attorneys, accountants, consultants,
bankers and financial advisors) (collectively, "Representatives"). The term
"Evaluation Material" does not include information which (i) can be shown by
written evidentiary materials already in your possession, provided that such
information is not known by you, after due inquiry, to be subject to another
confidentiality agreement with or other obligation of secrecy to the Company or
another party, (ii) becomes generally available to the public other than as a
result of a disclosure by you or any of your Representatives, or (iii) becomes
available to you on a non-confidential basis from a source other than the
Company or its advisors, provided that such source is not known by you, after
due inquiry, to be bound by a confidentiality agreement with or other obligation
of secrecy to the Company or another party.

You hereby agree that the Evaluation Material will be used solely for the
purpose of evaluating a possible transaction between the Company and you, and
that such information will be kept confidential by you and your Representatives;
provided, however, that (i) any of such information may be disclosed to your
Representatives who need to know such information for the purpose of evaluating
any such possible 


<PAGE>


Wolters Kluwer PLC

Page Two


transaction between the Company and you (it being understood that such
Representatives shall be informed by you of the confidential nature of such
information, shall be directed by you to treat such information confidentially,
and who shall agree to be bound by the terms and conditions of this Agreement),
and (ii) any disclosure of such information may be made to which the Company
consents in writing. You hereby agree to be responsible for any breach of this
Agreement by any of your Representatives (including any of your representatives
who, subsequent to the first date of disclosure of Evaluation Material
hereunder, become former Representatives) and shall take all necessary measures
to restrain your Representatives (or former Representatives) from unauthorized
disclosure or use of Evaluation Material.

You hereby acknowledge that you are aware, and that you will advise such of your
Representatives who are informed as to the matters which are the subject of this
letter, that the United States securities laws prohibit any person who has
received from an issuer material, non-public information concerning the matters
which are the subject of this letter from purchasing or selling securities of
such issuer or from communicating such information to any other person under
circumstances in which it is reasonably foreseeable that such person is likely
to purchase or sell such securities.

In addition, without the prior written consent of the Company, you will not, and
will direct your Representatives not to, disclose to any person either the fact
that discussions or negotiations are taking place concerning a possible
transaction between the Company and you or any of the terms, conditions or other
facts with respect to any such possible transaction, including the status
thereof.

You hereby acknowledge that the Evaluation Material is being furnished to you in
consideration of your agreement that you will not propose to the Company or any
other person any transaction between you and the Company and/or its security
holders or involving any of its securities or security holders unless the
Company shall have requested in writing that you make such a proposal, and that
you will not acquire, or assist, advise, participate with or encourage any other
persons in acquiring, directly or indirectly, control of the Company or any of
the Company's securities, businesses or assets for a period of twelve months
from the date of this letter unless the Company shall have consented in advance
in writing to such acquisition. You further agree, during such twelve-month
period, not to request the Company or any of its Representatives, directly or
indirectly, to amend or waive any provision of this paragraph (including this
sentence) or take any action which might require the Company to make a public
announcement regarding the possibility of a transaction. You also agree that the
Company shall be entitled to equitable relief, including injunction, in the
event of any breach of the provisions of this paragraph and that you shall not
oppose the granting of such relief.

Such remedy shall not be deemed to be the exclusive remedy, but shall be in
addition to all other remedies available at law or equity to the Company.

Although the Company has endeavored to include in the Evaluation Material
information known to it which it believes to be relevant for the purpose of your
investigation, you understand that neither the Company nor any of its
Representatives have made or make any representation or warranty as to the
accuracy or completeness of the Evaluation Material. You agree that neither the
Company nor its Representatives shall have any liability to you or any of your
Representatives resulting from the use of the Evaluation Material.

In the event that the Company so requests or you do not proceed with the
transaction which is the subject of this Agreement within a reasonable time, you
shall promptly redeliver to the Company all written Evaluation Material and any
other material containing or reflecting any Evaluation Material (whether
prepared by the Company or its advisors, you or your Representatives, or
otherwise in whatever form, together with all computer files, summaries,
extracts, abstracts, other documents or storage media which contain Evaluation
Material information in any form) and will not retain any copies, extracts or
other reproductions in whole or in part of such material. All documents,
memoranda, notes and other writings whatsoever prepared by you or your advisors
based on the information in the Evaluation Material shall be destroyed, and such
destruction shall be certified in writing to the Company by an authorized
officer supervising such destruction. Notwithstanding the return or destruction
of the Evaluation Material, you and your Representatives shall continue to be
bound by your respective obligations hereunder.

You agree that unless and until a definitive agreement between the Company and
you with respect to any transaction referred to in the first paragraph of this
Agreement has been executed and delivered, neither the Company nor you will be
under any legal obligation of any kind whatsoever with respect to such a
transaction by virtue of this or any written or oral expression with respect to
such a transaction by any of its directors, officers, employees, agents or any
other representatives or its advisors or representatives thereof except, in the
case of this Agreement, for the matters specifically agreed to herein. This
Agreement may be modified or waived only by a separate writing by the Company
and you expressly so modifying or waiving this Agreement.

                        STOCK OPTION AND TENDER AGREEMENT

     Stock Option and Tender Agreement (this "Agreement"), dated September 29,
1998, by and among Wolters Kluwer U.S. Corporation, a Delaware corporation
("Parent"), OTI Acquisition Corp., a Delaware corporation and a wholly-owned
subsidiary of Parent ("Sub"), and the stockholders set forth in Schedule I
hereto (each, a "Stockholder" and collectively, the "Stockholders").

                              W I T N E S S E T H:

     WHEREAS, Parent, Sub, and Ovid Technologies, Inc., a Delaware corporation
(the "Company") are entering into an Agreement and Plan of Merger (the "Merger
Agreement") pursuant to which Sub has agreed to make a tender offer (the
"Offer") for all outstanding shares of Common Stock, par value $.01 per share
(the "Common Stock"), of the Company at a price per share of Common Stock, based
upon the representations set forth in Section 3.2 of the Merger Agreement, of
$24.59 net to the seller in cash (such price, or such higher price per share of
Common Stock as may be paid in the Offer, being referred to herein as the "Offer
Price"), to be followed by a merger (the "Merger") of Sub with and into the
Company.

     WHEREAS, as a condition to the willingness of Parent and Sub to enter into
the Merger Agreement, each of Parent and Sub has required that each Stockholder
agree, and in order to induce Parent and Sub to enter into the Merger Agreement,
each Stockholder has agreed, among other things, subject to the provisions
contained herein, (i) to tender in the Offer all of the shares of Common Stock
now owned or which may hereafter be acquired by such Stockholder (the "Shares"),
(ii) to grant to Parent or Sub, as Parent shall designate (the "Optionee") the
option to purchase the Shares in certain circumstances, (iii) to appoint Parent
as such Stockholder's proxy under certain circumstances to vote the Shares in
connection with the Merger Agreement, (iv) with respect to certain questions put
to stockholders of the Company for a vote, to vote the Shares, in each case, in
accordance with the terms and conditions of this Agreement, and (v) to restrict
transfers or exercises of Company Options (as defined in Section 8 below), if
any, held by such Stockholder except as provided herein.

     NOW, THEREFORE, in consideration of the mutual covenants and agreements
contained herein and other good and valuable consideration, the adequacy of
which is hereby acknowledged, and intending to be legally bound hereby, the
parties hereto agree as follows:

     1. Tender of Shares. Each Stockholder severally (and not jointly) agrees to
tender and sell to Parent and/or Sub pursuant to the Offer all of the Shares
legally and/or beneficially owned by such Stockholder (as set forth on Schedule
I hereto) and that once tendered, each Stockholder agrees, subject to the
provisions of Section 2, that such Shares will not be withdrawn from the Offer
unless the Offer is terminated by Parent or Sub without any shares of Common
Stock being purchased thereunder. Each Stockholder severally (and not jointly)
agrees that such Stockholder shall deliver to the depositary for the Offer,
promptly, but not later than five (5) 


<PAGE>


days, following the commencement of the Offer, either a letter of transmittal
together with the certificates for the Shares, if available, or a "Notice of
Guaranteed Delivery", if the Shares are not available. Nothing contained in this
Agreement shall be deemed to require any Stockholder to exercise any Company
Option (as defined in Section 8).

     2. Stock Option.

          2.1 Grant of Stock Option. Each Stockholder hereby grants to Optionee
an irrevocable option (the "Stock Option") on the terms and conditions set forth
in this Section 2, to purchase all of the Shares legally and/or beneficially
owned by such Stockholder (as set forth on Schedule I hereto) (including Shares
subject to Company Options), at such time as Optionee may exercise the Stock
Option during the Exercise Period (as defined below), at a purchase price equal
to the Offer Price.

          2.2 Exercise of Stock Option. (a) Each Stock Option may be exercised
by Optionee, in whole and for all of such Stockholder's Shares but not in part
or for less than all of such Stockholder's Shares, and only simultaneously as to
all Stockholders (i) if the Offer has been terminated by Parent or Sub for the
reasons set forth in (f) or (g) of the Conditions to the Offer (as set forth in
Annex A to the Merger Agreement) or (ii) if the Offer has expired without the
purchase of Shares thereunder and at the time of such expiration (x) the Minimum
Condition (as defined in the Merger Agreement) has not been satisfied or (y)
circumstances had occurred giving rise to a right of termination by Parent or
Sub for the reasons set forth in (f) or (g) of said Conditions of the Offer, in
each case without any violation of the Offer or the Merger Agreement by Parent
or Sub. Notice of exercise may be given at any time during the period (the
"Exercise Period") commencing after the Stock Option becomes exercisable (under
the circumstances provided in this Section 2.2) and ending on the date which is
three months following the date on which any Superior Proposal (as defined in
the Merger Agreement) expires or is withdrawn or terminated without the purchase
of any Shares. In addition, Optionee may also exercise the Stock Option if the
Merger Agreement shall terminate by reason of the Company's exercise of its
termination rights pursuant to Section 7.1(c)(i)(a) or (b) of the Merger
Agreement, whereupon the Exercise Period shall commence on the date such
termination rights are exercised and end on the date which is three months
following the date on which any Superior Proposal expires or is withdrawn or
terminated without the purchase of any Shares.

               (b) In the event Optionee wishes to exercise the Stock Option,
Optionee shall send a written notice (an "Exercise Notice") during the Exercise
Period to each Stockholder specifying that Optionee shall purchase the total
number of Shares held by such Stockholder and a date, which shall be a business
day, and a place, which shall be in New York City, New York, for the closing of
such purchase (the "Stock Option Closing"). The Stock Option Closing shall be
delayed during such time as (I) any party shall be subject to a non-final order,
decree, ruling or action restraining, enjoining or otherwise prohibiting the
purchase of the Shares pursuant to the Stock Option or (II) the waiting period,
if any, under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as
amended, shall not have expired or been terminated.


                                       2
<PAGE>


               (c) Upon receipt of the Exercise Notice, each Stockholder shall
be obligated to deliver to Optionee, and Optionee shall be obligated to purchase
(and Parent shall cause Optionee to purchase), a certificate or certificates
representing the number of Shares held by such Stockholder (or to direct the
depositary for the Offer to so deliver such certificate or certificates), in
accordance with the terms of this Agreement, on the later of the date specified
in such Exercise Notice or the first business day on which the conditions
specified in Section 2.3 shall be satisfied. The date specified in such Exercise
Notice may be as early as one business day after the date of such Exercise
Notice but shall not be later than five (5) business days after the later of (i)
the date of such Exercise Notice, or (ii) the date all conditions under Section
2.3 are satisfied.

          2.3 Conditions to Delivery of the Shares. The obligation of the
Stockholders to deliver, and of the Optionee to pay for, the Shares upon
exercise of the Stock Option is subject to the following conditions:

               (a) All waiting periods under the Hart-Scott-Rodino Antitrust
Improvements Act of 1976, as amended, applicable to the exercise of the Stock
Option and the delivery of the Shares shall have expired or been terminated; and

               (b) There shall be no permanent injunction or other order by any
court of competent jurisdiction restricting, preventing or prohibiting the
exercise of the Stock Option or the delivery of the Shares in respect of such
exercise.

          2.4 Stock Option Closing. At the Stock Option Closing, each
Stockholder will deliver to Optionee a certificate or certificates evidencing
the number of Shares owned by such Stockholder, each such certificate being duly
endorsed in blank and accompanied by such stock powers and such other documents
as may be necessary in Optionee's judgment to transfer record ownership of the
Shares into Optionee's name on the stock transfer books of the Company, and
Optionee will purchase the delivered Shares at the Offer Price. All payments
made by Optionee to the Stockholders pursuant to this Section 2.4 shall be made
by wire transfer of immediately available funds or by certified bank check
payable to the Stockholders, in an amount for each Stockholder equal to the
product of (a) the Offer Price and (b) the number of Shares delivered by such
Stockholder in respect of the Stock Option Closing.

          2.5 Adjustments Upon Changes in Capitalization. In the event of any
change in the number of issued and outstanding shares of Common Stock by reason
of any stock dividend, subdivision, merger, recapitalization, combination,
conversion or exchange of shares, or any other change in the corporate or
capital structure of the Company (including, without limitation, the declaration
or payment of an extraordinary dividend of cash or securities) which would have
the effect of diluting or otherwise adversely affecting Optionee's rights and
privileges under this Agreement, the number and kind of the shares and the
consideration payable in respect of the Shares shall be appropriately and
equitably adjusted to restore to Optionee its rights and privileges under this
Agreement. Without limiting the scope of the foregoing, in any such event, at
the option of Optionee, the Stock Option shall represent the right to purchase,
in addition to the number and kind of Shares which Optionee would be entitled to


                                       3
<PAGE>


purchase pursuant to the immediately preceding sentence, whatever securities,
cash or other property the Shares subject to the Stock Option shall have been
converted into or otherwise exchanged for, together with any securities, cash or
other property which shall have been distributed with respect to such Shares.

          2.6 Tender of Shares by Stockholders in Connection with Tender Offer
Superior Proposal.

               (a) Notwithstanding anything herein to the contrary, and
notwithstanding that the Stock Option has become exercisable pursuant to Section
2.2 hereof, if at any time during the Exercise Period a tender offer pursuant to
any Superior Proposal (the "Superior Offer") is commenced, then, subject to the
terms and conditions of this Section 2.6, on the last day of the offer period of
the Superior Offer such Stockholders shall tender their Shares in the Superior
Offer. Concurrent therewith, if Optionee's tender offer is continuing at such
time, the Stockholders' Shares shall be released from Optionee's tender offer.
Subject to the provisions of Section 2.6(d), Optionee's right to exercise the
Stock Option shall be suspended for so long as the Superior Offer shall not have
expired or been terminated or withdrawn and, subject to the terms of this
Section 2.6, such right shall terminate simultaneously with the consummation of
the Superior Offer and receipt by the Stockholders of the consideration
therefor. Notwithstanding the foregoing, Optionee may elect, by written notice
to the Stockholders at any time prior to the tender of such Shares into the
Superior Offer by the Stockholders, to require the Stockholders, on a pro rata
basis, to retain Shares in an amount, as determined by Optionee, up to 25% of
the then outstanding shares of Common Stock on a fully diluted basis (the
"Minority Percentage"), whereupon the Stockholders shall not tender such amount
of Shares in the Superior Offer and Optionee's right to exercise the Stock
Option as to such Shares shall continue without limitation.

               (b) In the event that the Superior Offer is consummated, as to
Shares tendered by the Stockholders in accordance with paragraph (a) of this
Section 2.6, each Stockholder shall deliver to the Optionee that portion of the
consideration received by such Stockholder which is equal to the Incremental
Value (as defined below) multiplied by the number of Shares tendered by such
Stockholder in connection with such Superior Proposal. The Incremental Value
shall be determined as follows: If the consideration payable pursuant to the
Superior Offer is all cash, the Incremental Value shall equal the amount by
which the offer price in such Superior Proposal exceeds the Offer Price. If the
consideration payable consists of cash and securities or only securities, the
Incremental Value shall equal the amount by which (x) the sum of the cash, if
any, plus the value of the securities received in the Superior Proposal (the
amount of such cash and the value of such securities being determined on a per
share basis) exceeds (y) the Offer Price. The value of any publicly-traded
securities issued to the Stockholders upon consummation of the Superior Proposal
shall be determined by reference to the closing price of such securities on the
date of consummation of the Superior Proposal. The value of any securities which
have not previously been publicly traded ("Newly Registered Securities") shall
be determined by reference to the average closing price of such securities over
the twenty (20) trading days following consummation of the Superior Proposal.
Each Stockholder shall deliver to the Optionee the Incremental Value for each
Share held by such Stockholder immediately upon receipt if the consideration is
cash or cash and publicly-traded 


                                       4
<PAGE>


securities or, if the consideration includes Newly Registered Securities, upon
the later of receipt of the consideration or the date on which the value of the
securities is determined. The Incremental Value shall be payable to Optionee in
cash and securities in the same proportion as the cash and securities payable to
the Stockholders.

               (c) If Optionee has required the Stockholders to retain the
Minority Percentage, the Optionee will exercise the Stock Option with respect to
the Minority Percentage promptly upon the consummation of the Superior Offer.

               (d) In the event that the Superior Offer expires or is terminated
or withdrawn without purchase of the Shares tendered by the Stockholders, or if
the Stockholders breach their obligation to tender their Shares in the Superior
Offer or withdraw the tender of such Shares in such Superior Offer, Optionee's
right to exercise the Stock Option with respect to such Shares shall,
simultaneously with such expiration, termination, withdrawal or breach, be
restored.

          2.7 Voting of Shares in Connection with Merger Superior Proposal.

               (a) Notwithstanding the provisions of Section 5.1(a) and Section
7, in the event that the Superior Proposal is structured as a merger which is
not preceded by a tender offer, the Stockholders shall be permitted to vote such
Stockholders' Shares in favor of such merger; provided, however, that Optionee
may elect, by written notice to the Stockholders, to require the Stockholders to
abstain from voting in favor of the merger with respect to the Minority
Percentage. Subject to the provisions of Section 2.7(c), Optionee's right to
exercise the Stock Option shall be suspended so long as the Superior Proposal
described in this Section 2.7 shall not have expired or been terminated or
withdrawn and, subject to the terms of this Section 2.7, such right shall
terminate simultaneously with the consummation of the Superior Proposal
described in this Section 2.7 and receipt by the Stockholders of the
consideration therefor.

               (b) In the event that a Superior Offer described in this Section
2.7 is consummated, each Stockholder shall pay to Optionee, at the time
determined in accordance with Section 2.6(b), the Incremental Value (as
determined in accordance with Section 2.6(b)) received by such Stockholder for
each of such Stockholder's Shares.

               (c) In the event that the Superior Offer described in this
Section 2.7 expires or is terminated or withdrawn without purchase of the
Shares, or if the Stockholders fail to vote their Shares (other than the
Minority Percentage if so directed by Optionee) in favor of such Superior Offer,
Optionee's right to exercise the Stock Option with respect to such Shares, and
the restrictions on voting set forth in Section 5.1(a) and Section 7, shall,
simultaneously with such expiration, termination, withdrawal or breach, be
restored.

          2.8 Tender Offer Upon Exercise of Stock Option. Parent and Sub hereby
agree that, in the event that (pursuant to the Stock Option) Optionee purchases
an amount of the Stockholders' Shares greater than the Minority Percentage, then
as promptly as practicable (and in any event within five (5) business days
thereafter), Sub will, and Parent will cause Sub to, make a tender offer to the
stockholders of the Company for the remaining shares of Common 


                                       5
<PAGE>


Stock (the consummation of which shall be subject only to the conditions that no
court, arbitrator or governmental body, agency or official shall have issued any
order, decree or ruling and there shall not be any statute, rule or regulation,
enjoining or prohibiting the consummation of such tender offer) pursuant to
which the stockholders of the Company (other than the Company, any direct or
indirect subsidiary of the Company or Parent or Sub) will be entitled to receive
an amount of cash consideration per share of Common Stock equal to the Offer
Price, and will take such actions as may be necessary or appropriate to
effectuate, and purchase shares of Common Stock pursuant to, such tender offer
at the earliest practicable time.

          2.9 Termination. This Agreement will terminate and be of no further
force and effect if, as a result of the failure of any conditions to such Stock
Option Closing to be satisfied, the Stock Option Closing shall not have occurred
within one (1) year following delivery of the Exercise Notice; provided,
however, that Optionee shall have the right, by delivery of written notice to
the Stockholders, to extend this Agreement for thirty (30) days if Optionee
reasonably believes that any conditions to the Stock Option Closing which remain
unsatisfied may be satisfied during such thirty (30) day period.

     3. Representations and Warranties of Stockholders.

     Each Stockholder severally (and not jointly), represents and warrants to
Parent and Sub that:

          3.1 Power and Authority. Such Stockholder has all necessary power and
authority to enter into this Agreement and to sell, assign, transfer and deliver
to Parent and/or Sub, pursuant to the terms and conditions of this Agreement and
the Merger Agreement, the Shares legally and/or beneficially owned by such
Stockholder (as set forth on Schedule I hereto).

          3.2 No Other Rights. Except for this Agreement, there are no
outstanding options, warrants or rights to purchase or acquire such Shares of
such Stockholder.

          3.3 Only Shares. Such Shares of such Stockholder subject to this
Agreement are the only shares of Common Stock owned of record, or owned
beneficially with the power to sell, by such Stockholder.

          3.4 Title. Except as specifically disclosed on Schedule 5.1 to the
Merger Agreement, such Stockholder has, and upon the closing of the Offer, Sub
shall receive good and marketable title to such Shares of such Stockholder, free
and clear of all liens, claims, encumbrances and security interests of any
nature whatsoever.

          3.5 Validity. This Agreement is the legal, valid and binding agreement
of such Stockholder enforceable against such Stockholder in accordance with its
terms, except as enforcement may be limited by bankruptcy, insolvency,
moratorium or other similar laws relating to creditors' rights generally and
except that the availability of equitable remedies, including specific
performance, is subject to the discretion of the court before which any
proceeding therefor may be brought.

<PAGE>


          3.6 Non-Contravention. The execution and delivery of this Agreement
does not, and the consummation of the transactions contemplated hereby and
compliance with the provisions hereof will not, conflict with, or result in any
violation of, or default (with or without notice or lapse of time, or both) by
Stockholder under, or give rise to a right of termination, cancellation or
acceleration of any obligation under, or result in the creation of any lien,
security interest, charge or encumbrance upon any of the properties or assets of
such Stockholder under, any provision of (i) the charter or organizational
documents of such Stockholder, if any (ii) any loan or credit agreement, note,
bond, mortgage, indenture, lease or other agreement, instrument, permit,
concession, franchise or license applicable to such Stockholder or (iii) any
judgment, order, decree, statute, law, ordinance, rule or regulation applicable
to such Stockholder or any of its properties or assets, other than, in the case
of clauses (ii) and (iii), any such conflicts, violations, defaults, rights,
liens, security interests, charges or encumbrances that, individually or in the
aggregate, would not materially impair the ability of such Stockholder to
perform its obligations hereunder or prevent, limit or restrict the consummation
of any of the transactions contemplated hereby.

     4. Representations and Warranties of Parent and Sub. Parent and Sub hereby
represent and warrant to each Stockholder as follows:

          4.1 Power and Authority. Each of Parent and Sub has all necessary
power and authority to enter into the Agreement and to purchase the Shares
pursuant to the terms and conditions of this Agreement and the Merger Agreement.

          4.2 Sufficient Funds. Parent and/or Sub has, or prior to the date of
the Stock Option Closing will have, all of the funds necessary to consummate the
transactions contemplated hereby on a timely basis and to pay any and all of its
related fees and expenses.

          4.3 Validity. This Agreement is the legal, valid and binding agreement
of Parent and Sub enforceable against them in accordance with its terms, except
as enforcement may be limited by bankruptcy, insolvency, moratorium or other
similar laws relating to creditors' rights generally and except that the
availability of equitable remedies, including specific performance, is subject
to the discretion of the court before which any proceeding therefor may be
brought.

          4.4 Non-Contravention. The execution and delivery of this Agreement
does not, and the consummation of the transactions contemplated hereby and
compliance with the provisions hereof will not, conflict with, or result in any
violation of, or default (with or without notice or lapse of time, or both)
under, or give rise to a right of termination, cancellation or acceleration of
any obligation under, or result in the creation of any lien, security interest,
charge or encumbrance upon any of the properties or assets of Parent, Sub or any
of Parent's other subsidiaries which are both owned directly or indirectly by
Parent and which directly or indirectly owns Sub ("Owning Subs") under, any
provision of (i) the Charter or Bylaws of Parent (or any comparable
organizational documents) or any provision of the comparable charter or
organizational documents of Sub or any Owning Sub, (ii) any loan or credit
agreement, note, 


                                       7
<PAGE>


bond, mortgage, indenture, lease or other agreement, instrument, permit,
concession, franchise or license applicable to Parent, Sub or any Owning Sub or
(iii) any judgment, order, decree, statute, law, ordinance, rule or regulation
applicable to Parent, Sub or any Owning Sub or any of their respective
properties or assets, other than, in the case of clauses (ii) or (iii), any such
conflicts, violations, defaults, rights, liens, security interests, charges or
encumbrances that, individually or in the aggregate would not have a Parent
Material Adverse Effect (as defined in the Merger Agreement), materially impair
the ability of Parent or Sub to perform its obligations hereunder or prevent,
limit or restrict the consummation of any of the transactions contemplated
hereby.

     5. Covenants of Stockholders.

          5.1 No Disposition or Encumbrance of Shares; No Acquisition of Shares.
(a) Each Stockholder severally (and not jointly) covenants and agrees that,
except as contemplated by this Agreement, no Stockholder shall, and no
Stockholder shall offer or agree to, sell, transfer, tender, assign, hypothecate
or otherwise dispose of, or create any security interest, lien, claim, pledge,
option, right of first refusal, agreement, limitation on such Stockholder's
voting rights, charge or other encumbrance of any nature whatsoever with respect
to the Shares now legally and/or beneficially owned by, or that may hereafter be
acquired by, such Stockholder. Each Stockholder severally (and not jointly)
agrees that such Stockholder shall not grant any proxy or power of attorney with
respect to the voting of Shares (each a "Voting Proxy") to any person except to
vote in favor of any of the transactions contemplated by this Agreement or the
Merger Agreement. Each Stockholder hereby represents and warrants that such
Stockholder has granted no Voting Proxy which is currently (or which will
hereafter become) effective with respect to Shares owned by such Stockholder
except Voting Proxies, if any, granted to another Stockholder, and if such
Stockholder has granted a Voting Proxy to any person other than a Stockholder,
such Voting Proxy is hereby revoked. No Voting Proxy shall be given or written
consent executed by such Stockholder after the date hereof with respect to such
Stockholder's Shares (and if given or executed, shall not be effective) so long
as this Agreement remains in effect; provided, however, that such Stockholder
may hereafter grant Voting Proxies in furtherance of such Stockholder's
obligations under Section 7.1 hereof.

               (b) Each Stockholder hereby severally (and not jointly) covenants
and agrees that it shall not, and shall not offer to agree to, acquire any
additional shares of Common Stock, or options, warrants or other rights to
acquire shares of Common Stock (except upon exercise of stock options presently
held by such Stockholder), without the prior written consent of Parent or Sub.

          5.2 No Solicitation of Transactions. Each Stockholder shall
immediately cease any existing discussions or negotiations, if any, with any
parties conducted heretofore with respect to any acquisition or exchange of all
or any material portion of the assets of, or any equity interest in, the Company
or any of its subsidiaries or any business combination with the Company or any
of its subsidiaries. From and after the date hereof, no Stockholder shall,
directly or indirectly, solicit or initiate any takeover proposal or offer from
any person, or (except to the extent permitted by the last sentence of Section
5.2 of the Merger Agreement) engage in discussions or negotiations relating
thereto (including by way of furnishing information). Each 


                                       8
<PAGE>


Stockholder shall promptly advise Parent of the receipt of any Alternative
Proposal (as defined in the Merger Agreement). Notwithstanding anything to the
contrary contained herein, the provisions of this Section 5.2 shall not limit or
restrict in any manner whatsoever any Stockholder's actions or conduct as a
director or representative of the Company.

          5.3 Stockholders' Representative. Each Stockholder hereby appoints
Mark L. Nelson as Stockholders' Representative to act as Stockholders'
Representative for purposes of giving and receiving notices under this
Agreement.

     6. Covenants of Parent and Sub.

          6.1 No Sale. Neither Parent nor Sub will sell, offer to sell or
otherwise dispose of the Shares in violation of the Securities Act of 1933, as
amended.

          6.2 Performance. Parent and Sub shall perform in all material respects
all of their respective obligations under the Merger Agreement.

     7. Voting Agreement: Proxy of Stockholder.

          7.1 Voting Agreement. (a) Each Stockholder hereby severally (and not
jointly) agrees that, during the time this Agreement is in effect, at any
meeting of the stockholders of the Company, however called, and in any action by
written consent of the stockholders of the Company, such Stockholder shall (i)
vote all of the Shares legally and/or beneficially owned by such Stockholder in
favor of the Merger, the Merger Agreement (as amended from time to time) and any
of the transactions contemplated by the Merger Agreement; (ii) vote such Shares
against any action or agreement that would result in a breach in any material
respect of any covenant, representation or warranty or any other obligation of
the Company under the Merger Agreement; and (iii) vote the Shares against any
action or agreement that would materially impede, interfere with or attempt to
discourage the Offer or the Merger.

               (b) Each Stockholder hereby severally (and not jointly) further
agrees that, if the Merger Agreement shall terminate solely by reason of the
Company's exercise of its termination rights pursuant to Section 7.1(c)(i)(a) or
(b) of the Merger Agreement and for as long as the Exercise Period has not
ended, such Stockholder (i) shall attend or otherwise participate in all duly
called stockholder meetings and in all actions by written consent of
stockholders, (ii) shall not, without the prior written consent of Parent or
Sub, vote any of such Shares in favor of any actions requiring stockholder
approval which are described in Section 5 of the Merger Agreement and (iii)
shall otherwise vote such Shares, and use its reasonable efforts in its capacity
as stockholder of the Company, to prevent the actions prohibited by Section 5 of
the Merger Agreement.

          7.2 Irrevocable Proxy. In the event that any Stockholder shall breach
its covenant set forth in Section 7.1, such Stockholder (without any further
action on such Stockholder's part) shall be deemed to have hereby irrevocably
appointed Parent as the attorney-in-fact and proxy of such Stockholder, with
full power of substitution, to vote, and otherwise act 


                                       9
<PAGE>


(by written consent or otherwise) with respect to all shares of Common Stock
(including the Shares) that such Stockholder is entitled to vote at any meeting
of stockholders of the Company (whether annual or special and whether or not an
adjourned or postponed meeting) or consent in lieu of any such meeting or
otherwise to vote such shares as set forth in Section 7.1 above; provided that
in any such vote or other action pursuant to such proxy, Parent shall not have
the right (and such proxy shall not confer the right) to vote to reduce the
Offer Price or the Merger Consideration (as defined in the Merger Agreement) or
to otherwise modify or amend the Merger Agreement to reduce the rights or
benefits of the Company or any stockholders of the Company (including the
Stockholders) under the Offer or the Merger Agreement or to reduce the
obligations of Parent and/or Sub thereunder; and provided further, that this
proxy shall irrevocably cease to be in effect at any time that (x) the Offer
shall have expired or terminated without any shares of Common Stock being
purchased thereunder, in violation of the terms of the Offer or the Merger
Agreement or (y) Parent or Sub shall be in violation of the terms of this
Agreement. THIS PROXY AND POWER OF ATTORNEY IS IRREVOCABLE AND COUPLED WITH AN
INTEREST AND IS EXECUTED AND INTENDED TO BE IRREVOCABLE IN ACCORDANCE WITH THE
PROVISIONS OF SECTION 212(e) OF THE DELAWARE GENERAL CORPORATION LAW. Each
Stockholder shall execute and deliver to Parent any proxy cards that such
Stockholder receives to vote in favor of the consummation of the Merger. Parent
shall deliver to the Secretary of the Company any such proxy cards received by
it at any meeting called to approve the consummation of the Merger.

     8. Transfer of Options. Each of the Stockholders identified on Schedule I
hereto as holding options to purchase shares of Common Stock of the Company
(each a "Company Option") severally (and not jointly) agrees that so long as
this Agreement shall remain in effect, such Stockholder (for purposes of this
Section 8, an "Optionholder") will not transfer any Company Options held by such
Optionholder; provided, however, that at the Effective Time, (as defined in the
Merger Agreement) each Optionholder agrees to accept an amount in respect of
such Company Options equal to the product of (A) the excess, if any, of the
Offer Price over the per share exercise price of each such Company Option and
(B) the number of Shares subject thereto (such payment to be net of applicable
withholding taxes) and each such Company Option shall thereafter be canceled.

     9. Indemnification

          9.1 Agreement to Indemnify. Notwithstanding the provisions of Section
8.2 of the Merger Agreement regarding the non-survival of the Company's
representations and warranties contained in the Merger Agreement, Mark L. Nelson
(the "Indemnitor") agrees as follows:

               (a) To indemnify, defend and hold harmless Parent and Sub (each,
an "Indemnified Party") and their affiliates (including any officer, director,
stockholder, partner, member, employee, agent or representative of any thereof)
(each a "Parent Affiliate") to the extent provided in Section 9.5 from and
against all assessments, losses, damages, liabilities, costs and expenses,
including without limitation interest, penalties and reasonable fees and
expenses of legal counsel chosen by Parent, Sub or Parent Affiliate
(collectively, "Damages"), imposed upon 


                                       10
<PAGE>


or incurred by Parent, Sub or any Parent Affiliate arising out of or in
connection with or resulting from any breach of any representation or warranty
of the Company, or nonfulfillment, at any time prior to the consummation of the
Offer, of any covenant or agreement by the Company, in each case contained in or
made pursuant to the Merger Agreement or any Schedule thereto, or any
certificate furnished or to be furnished to Parent or Sub thereunder.

               (b) The Indemnitor shall reimburse an Indemnified Party promptly
after delivery of an Indemnification Notice certifying that the Indemnified
Party has incurred Damages after compliance with the terms of this Section 9,
provided, however, that the Indemnitor shall have the right to contest any such
Damages in good faith.

               (c) Notwithstanding anything herein to the contrary, Indemnitor
shall have no indemnification obligations hereunder unless Parent and Sub have
consummated the Offer or have purchased the Shares pursuant to the Stock Option.

          9.2 Notice of Damages. An Indemnified Party will give the Indemnitor
prompt notice (hereinafter, the "Indemnification Notice") of any demands,
claims, actions or causes of action (collectively, "Claims") asserted against
the Indemnified Party. Failure to give such notice shall not relieve the
Indemnitor of any obligations which the Indemnitor may have to the Indemnified
Party under this Section 9, except to the extent that such failure has
materially adversely prejudiced the Indemnitor under the provisions for
indemnification contained in this Agreement.

          9.3 Conditions of Indemnification of Third Party Claims. The
obligations and liabilities of Indemnitor under Section 9.1 hereof with respect
to Damages resulting from Claims by persons not party to the Merger Agreement
shall be subject to the following terms and conditions:

               (a) The Indemnified Party will have the right (upon further
notice to the Indemnitor) to undertake the defense, compromise or settlement of
such Claim for the account of the Indemnitor, subject to the right of the
Indemnitor to participate in the defense of such Claim pursuant to the terms of
paragraph (b) of this Section 9.3 at any time prior to settlement, compromise or
final determination thereof.

               (b) After delivery of an Indemnification Notice in respect of a
Claim and subject to paragraph (c) of this Section 9.3, the Indemnitor may
elect, by written notice to the Indemnified Party, to participate in the defense
thereof with counsel reasonably satisfactory to the Indemnified Party. If the
Indemnitor chooses to participate in the defense of any claim, the Indemnified
Party shall cooperate with all reasonable requests of the Indemnitor and shall
make available to the Indemnitor any books, records or other documents within
its control that are necessary or appropriate for such defense.

               (c) The Indemnitor shall not, without written consent of all
Indemnified Parties, settle or compromise any Claim or consent to entry of any
judgment which does not include as an unconditional term thereof the release by
the claimant or the plaintiff of all 


                                       11
<PAGE>


Indemnified Parties from all liability arising from events which allegedly give
rise to such Claim.

               (d) Until such time as the amount of Damages incurred by the
Indemnified Party exceeds $5,000,000, all fees and expenses of counsel selected
by Indemnitor incurred in participating in the defense of such Claim shall be
borne solely by Indemnitor. From and after such time as the amount of Damages
incurred by the Indemnified Party exceeds $5,000,000, subject to paragraph (e)
of this Section 9.3, the reasonable fees and expenses of counsel to Indemnitor
thereafter incurred, together with the reasonable fees and expenses of counsel
to Indemnitor incurred by Indemnitor prior to such time as the Damages of the
Indemnified Party exceed $5,000,000, shall be considered additional Damages for
purposes of this Section 9.

               (e) If the Indemnified Party desires not to defend any Claim or
to settle or compromise any Claim or consent to entry of any judgment with
respect to such Claim, the Indemnified Party shall provide written notice (the
"Proposed Settlement Notice") to the Indemnitor of such desire, which Proposed
Settlement Notice shall state the amount of Damages which the Indemnified Party
is prepared to incur as a result of such settlement, compromise or entry of
judgment (the "Proposed Damage Limit"). Indemnitor shall have the right, by
written notice to the Indemnified Party within ten (10) days after receipt of
the Proposed Settlement Notice, to assume the defense of such Claim and to
employ its own counsel in the defense of such Claim; provided, however, that
upon the final determination of Damages with respect to such Claim, any Damages
(including counsel fees and expenses) in excess of the Proposed Damage Limit
shall be borne solely by Indemnitor and shall not be considered Damages for
purposes of making any determinations pursuant to Section 9.5 as to the amount
for which Indemnitor may be responsible.

          9.4 Limitation on Indemnification. Notwithstanding anything to the
contrary provided elsewhere in the Merger Agreement, the obligations of any
Indemnitor under this Agreement to indemnify any Indemnified Party with respect
to any Claim pursuant to Section 9.2 shall be of no force and forever barred
unless the Indemnified Party has given the Indemnitor notice of such claim prior
to such date which is eighteen (18) months after the consummation of the Offer
or the Stock Option Closing, as the case may be. In any event, the parties shall
fully cooperate with each other and their respective counsel in accordance with
Section 9.3 in connection with any such litigation, defense, settlement or other
attempted resolution.

          9.5 Limitation upon Indemnification Obligations. Indemnitor shall not
be required to indemnify any Indemnified Party until such time as the Damages in
the aggregate equal or exceed five million dollars ($5,000,000.00). Thereafter,
Indemnitor's indemnification obligations hereunder shall apply to 100% of the
next $5,000,000 of Damages, and 50% of the next $20,000,000 of Damages. No
indemnification shall be required by Indemnitor for any Damages in the aggregate
in excess of $30,000,000 (i.e., Indemnitor's maximum liability for Damages under
this Section 9 shall not exceed $15,000,000).

     10. Effectiveness: Termination: No Survival. This Agreement shall become
effective as to each Stockholder upon its execution by such Stockholder, Parent
and Sub hereto and upon 


                                       12
<PAGE>


the execution of the Merger Agreement. This Agreement may be terminated as to
each Stockholder at any time by mutual written consent of such Stockholder,
Parent and Sub. Other than the Stock Option, which shall be governed by Section
2, and the indemnification provisions which shall be governed by Section 9, this
Agreement shall terminate (including without limitation the provisions of
Section 1), without any action by the parties hereto, on the date on which the
Merger Agreement terminates in accordance with its terms. No such termination
shall relieve any party from liability for any breach of this Agreement. The
representations and warranties of the parties set forth in Sections 3 and 4
hereof shall not survive the termination of this Agreement (except that if the
Stock Option is duly exercised, Sections 3.1, 3.2, 3.4 and 3.5 shall survive the
exercise of the Stock Option and the purchase of the Shares pursuant thereto,
regardless of any investigation made by Parent or Sub).

     11. Miscellaneous.

          11.1 Notices. Any notice request, instruction or other document to be
given hereunder by any party to the other parties shall be in writing and
delivered personally or sent by overnight courier, registered or certified mail,
postage prepaid, or by facsimile transmission (with a confirming copy sent by
overnight courier), as follows:

                                [Ovid Letterhead]
 

                                                                 October 5, 1998
To the Stockholders of
Ovid Technologies, Inc.:

     We are pleased to inform you that on September 29, 1998, Ovid Technologies,
Inc. ("Ovid" or the "Company") entered into an Agreement and Plan of Merger
(the "Merger Agreement") with Wolters Kluwer U.S. Corporation ("Parent") and
OTI Acquisition Corp. ("OTI Acquisition"), an indirect wholly owned subsidiary
of Parent, pursuant to which OTI Acquisition has today commenced a tender offer
(the "Offer") to purchase all of the outstanding shares of common stock, $.01
par value per share (the "Shares"), of the Company, for $24.59 per Share in
cash. Under the terms of the Merger Agreement, following the successful
completion of the Offer, OTI Acquisition will be merged (the "Merger") with
and into the Company and all Shares not purchased in the Offer (other than
Shares held by Parent, OTI Acquisition or any other wholly owned subsidiary of
Parent, Shares owned by the Company as treasury stock, and Shares held by
stockholders who have properly exercised appraisal rights under Delaware law, if
any) will be converted into the right to receive $24.59 per Share in cash.

     In addition, following consummation of the Merger, all outstanding stock
options of the Company, whether or not then vested, will be converted into the
right to receive from the Company an amount of cash equal to the product of (i)
the number of Shares subject to such options and (ii) the excess of $24.59 over
the exercise price of such option.

     Your Board of Directors has unanimously approved the Merger Agreement, the
Offer and the Merger and has determined that the Offer and the Merger are fair
to and in the best interests of Ovid's stockholders. The Board unanimously
recommends that the Company's stockholders accept the Offer and tender their
Shares in the Offer.

     In arriving at its recommendation, the Board of Directors gave careful
consideration to a number of factors described in the attached Schedule 14D-9
that is being filed today with the Securities and Exchange Commission including,
among other things, the opinion of Goldman, Sachs & Co., the Company's financial
advisor, to the effect that, as of September 29, 1998, the $24.59 in cash to be
received by the Company's stockholders in the Offer and the Merger is fair from
a financial point of view to the Company's stockholders. The full text of the
written opinion of Goldman, Sachs & Co., dated September 29, 1998, which sets
forth the assumptions made, matters considered and limitations on the review
undertaken in connection with the opinion, is attached to the Schedule 14D-9 as
Annex A. All stockholders are urged to, and should, read the opinion of Goldman,
Sachs & Co. carefully in its entirety


     In addition to the attached Schedule 14D-9 relating to the Offer, also
enclosed is the Offer to Purchase, dated October 5, 1998, of OTI Acquisition,
together with related materials, including a Letter of Transmittal to be used
for tendering your Shares. These documents set forth the terms and conditions of
the Offer and the Merger and provide instructions as to how to tender your
Shares. We urge you to read the enclosed materials carefully.


                                     Sincerely,

 

                                     /s/ Mark L. Nelson

                  WOLTERS KLUWER WILL ACQUIRE OVID TECHNOLOGIES
                         FOR APPROXIMATELY $200 MILLION

- --------------------------------------------------------------------------------


NEW YORK, NY, and CHICAGO SEPTEMBER 29, 1998--Wolters Kluwer U.S. Corporation,
a wholly-owned subsidiary of Wolters Kluwer N.V., and Ovid Technologies, Inc.
[NASDAQ: OVID] today announced that they have entered into a definitive
agreement pursuant to which Wolters Kluwer will acquire all outstanding shares
of Ovid on a fully diluted basis for $24.59 per share, or approximately U.S.
$200 million, in cash.

Pursuant to the terms of the definitive merger agreement, Wolters Kluwer shall
commence a cash tender offer for Ovid's common stock no later than October 5,
1998. As part of the transaction, Mark Nelson, President and Chief Executive
Officer of Ovid, and certain other shareholders, who currently beneficially own
an aggregate of approximately 5.1 million shares of Ovid, or approximately 63%
of the outstanding shares (on a fully diluted basis), have agreed to tender
their outstanding shares and have granted to Wolters Kluwer an option, under
certain circumstances, to buy all their shares for $24.59 per share.

The tender offer is conditioned upon the tendering of shares representing a
majority of Ovid's outstanding common stock (on a fully diluted basis),
satisfaction of applicable regulatory requirements and certain other customary
conditions. Any shares not purchased in the tender offer will be acquired in a
second-step merger for $24.59 per share in cash. Holders of employee stock
options will receive cash in an amount equal to the difference between the offer
price and their option exercise price.

The agreement obligates Ovid to pay to Wolters Kluwer a fee of $7 million and up
to $500,000 of expense reimbursement, if the transaction is not consummated
under certain circumstances.

Ladies and Gentlemen:

     In order to induce Wolters Kluwer U.S. Corporation ("WKUS") to commit the
resources, forego other potential opportunities, and incur the legal,
accounting, and incidental expenses necessary to properly evaluate acquiring
100% of the equity of Ovid Technologies, Inc. (the "Company") and to negotiate
the terms of definitive documentation with respect thereto, the Company and Mark
Nelson ("Nelson") agree that

(a) WKUS will have exclusive negotiating rights which will expire on the earlier
of (i) Monday, September 28, 1998 at 5:00 p.m. or (ii) the time at which the
discussions and negotiations with respect to the possible acquisition of the
equity have been finally terminated by WKUS) (the "Expiration Time"). That is,
from and after the date hereof and prior to the Expiration Time, (i) the Company
will not (and will cause its officers, directors, employees, representatives and
agents not to) and Nelson will not, (A) initiate, solicit or encourage, directly
or indirectly, or conduct negotiations with respect to any proposal or offer for
a merger, asset acquisition or other business combination involving the Company
or any proposal or offer to acquire a significant equity interest in, or a
significant portion of the assets of, the Company (collectively, an "Acquisition
Proposal") with any person, or otherwise contact any prospective buyer, other
than WKUS or (B) enter into any agreement or provide any confidential
information or data to any person in connection with or relating to any such
Acquisition Proposal; (ii) each of such persons will immediately cease (and will
cause its representatives to cease) any existing discussions or negotiations, if
any, with any parties conducted heretofore with respect to any such Acquisition
Proposal; and (iii) each of such persons will notify (and will cause its
representatives to notify) WKUS as soon as practicable if any such inquiries or
proposals are received by, any such information is requested from, or any such
negotiations and/or discussions are sought to be initiated or continued with,
the Company or Nelson.

     (b) The Company will continue to allow the representatives of WKUS to meet
with the management of the Company (at reasonable times so as not to interfere
with the operation of the Company) to examine (but not retain) the Company's
financial, accounting, and business records, assets and liabilities, and all of
its contracts and other legal documents, and generally to conduct a commercial,
accounting, and legal investigation of the business and affairs of the Company.
Such investigation, and any information obtained by WKUS as a result thereof,
will be maintained by WKUS in confidence in accordance with our previously
signed confidentiality agreement and will not be used or disclosed by WKUS if
for any reason the transaction contemplated hereby is not consummated except to
the extent

permitted by such agreement. The results of such due diligence reviews must
continue to be satisfactory to WKUS. The due diligence review will be completed
by the execution of definitive documentation.

     (c) None of the Company, Nelson nor WKUS (subject to requirements of law)
will make any announcement regarding this letter or any transaction which
results from the contemplated negotiations without the prior approval of both
the Company and WKUS, having regard for the fact that timely announcements may
be required by law to be made to the financial and general press in the United
States and the Netherlands. Accordingly, the Company and WKUS agree not to
withhold or delay approval of such announcements unreasonably.

     (d) The Company and WKUS shall each pay their respective expenses incident
to the negotiations, due diligence and the preparation of definitive
documentation.

please so indicate by executing a copy of this letter in the space provided
