                            STOCK PURCHASE AGREEMENT


         AGREEMENT, dated as of November 10, 1998, by and among NFO EUROPE
(DEUTSCHLAND) GMBH & CO. KG, a German limited partnership (the "Buyer"), NFO
WORLDWIDE, INC., a Delaware corporation ("NFO"), and THE HOLDERS LISTED ON
SCHEDULE 1.2 (each a "Seller" and, collectively, the "Sellers"), for the
purchase and sale of all of the issued and outstanding shares of capital stock
of INFRATEST BURKE AKTIENGESELLSCHAFT HOLDING, a German AKTIENGESELLSCHAFT
(stock corporation) (the "Company").

         The Buyer is a wholly owned indirect subsidiary of NFO. The Sellers are
the legal and beneficial owners of all of the issued and outstanding shares of
common stock, par value DM50 per share (the "Shares"), of the Company. The
Sellers wish to sell to the Buyer, and the Buyer wishes to purchase from the
Sellers, all of the Shares upon the terms and subject to the conditions of this
Agreement.

         Certain terms used in this Agreement are defined in Section 13.1.

         Accordingly, the parties agree as follows:

         1. Sale and Purchase of Shares; Assumption of Liabilities.

                  1.1 Sale and Purchase of Shares. At the closing provided for
in Article 2 (the "Closing"), upon the terms and subject to the conditions of
this Agreement and in reliance upon the representations, warranties and
agreements of the Sellers, the Buyer and NFO contained herein, the Sellers shall
sell to the Buyer, and the Buyer shall 


                                                                               2

purchase from the Sellers, all of the Shares for an aggregate purchase price
(the "Purchase Price") equal to DM 200,000,000, to be paid in cash in accordance
with Section 1.2.

                  1.2 Payment of Purchase Price. The Buyer shall pay the
Purchase Price to the Sellers at the Closing by the wire transfer of immediately
available funds allocated in the amount of DM 120 million to Equita
Beteiligungen KGaA, in the amount of DM 50 million to Dr. Lena-Renate Ernst, in
the amount of DM 20 million to Dr. Hartmut Kiock and in the amount of DM 10
million to Werner Hampf. It is hereby agreed that the Purchase Price shall be
transferred to the account in the United States set forth on Schedule 1.2 and
that the Sellers shall bear responsibility for transferring the Purchase Price
from such account into individual accounts for each Seller. Notwithstanding the
foregoing, following the Closing the Purchase Price shall be subject to
adjustment in accordance with Section 1.5 hereof.

                  1.3 Delivery of Shares. At the Closing, each Seller shall
deliver to the Buyer stock certificates representing the number of Shares set
forth opposite such Seller's name on Schedule 1.3, such bearer shares
collectively constituting all of the outstanding capital stock of the Company.

                  1.4 Transfer of Shares. At the Closing, each of the Sellers
and the Buyer shall execute a stock transfer document in the form attached as
Exhibit A (the "Transfer Document").

                  1.5 Adjustment of Purchase Price after the Closing. The
Purchase Price shall be subject to adjustment after the Closing as specified in
this Section 1.5 hereof:


                                                                               3

                           (a) As promptly as practical, but in any event within
seventy-five (75) calendar days after the Closing Date, the Sellers shall cause
Haarmann, Hemmelrath & Partners GmbH (the "Sellers' Accountants") to deliver to
NFO and the Buyer (I) an audited consolidated balance sheet of the Company as of
September 30, 1998, and the related consolidated statement of income, including
the notes (ANHANG) thereto, for the business year then ended (the "1998
Financials"), together with (II) a report (such report being the "Preliminary
Closing Statement") thereon of the Sellers' Accountants (x) stating that the
1998 Financials fairly present the consolidated financial position of the
Company and the entities consolidated therein as at September 30, 1998 and the
consolidated results of operations of the Company and the entities consolidated
therein for the period covered thereby, in each case in accordance with German
GAAP applied on a basis consistent with past periods and (y) setting forth
calculations of the Net Worth of the Company and the 1998 Consolidated Entities
(as defined in Section 13.1) (computed in the manner set forth in the defined
term Net Worth) as of the close of business on September 30, 1998 and of EBITDA
of the Company and the 1998 Consolidated Entities (as defined in Section 13.1)
(computed in the manner set forth in the defined term EBITDA) for the twelve
months ended September 30, 1998. Following the Closing, the Buyer shall provide
to the Sellers and the Sellers' Accountants reasonable access during normal
business hours to the books and records of the Company and the 1998 Consolidated
Entities relevant for the preparation of the 1998 Financials and the Preliminary
Closing Statement. The procedures and methods used to prepare the 


                                                                               4

Preliminary Closing Statement shall be those utilized in preparing the Company's
statutory audit.

                           (b) NFO, the Buyer and their authorized
representatives shall have the right to review the books and records and work
papers of the Sellers and the Sellers' Accountants for the purpose of verifying
the 1998 Financials and the Preliminary Closing Statement. The Buyer may dispute
any amounts reflected on the Preliminary Closing Statement in respect of either
Net Worth or EBITDA by giving the Sellers notice in writing of each disputed
item, specifying the amount thereof in dispute and setting forth, in reasonable
detail, the basis for such dispute, within sixty (60) days of the Buyer's
receipt of the Preliminary Closing Statement. In the event of such a dispute,
the Sellers' Accountants and the Buyer's accountant shall attempt to reconcile
their differences, and any resolution by them as to any disputed amounts shall
be final, binding and conclusive on the parties hereto. If the parties are
unable to resolve the dispute within sixty (60) days after receipt by the
Sellers of the Buyer's written notice of dispute, the Sellers' Accountants and
the Buyer's accountant shall submit the items remaining in dispute for
resolution to an Independent Accounting Firm, which shall, within sixty (60)
days after such submission, determine and report to the Sellers and the Buyer
upon such remaining disputed items. The fees and disbursements of the
Independent Accounting Firm shall be allocated between the Sellers, on the one
hand, and the Buyer, on the other hand, in proportion to their relative success,
as determined by the Independent Accounting Firm, in connection with the final
disposition of disputed items. The determination of the Independent Accounting
Firm shall be final and binding upon the 


                                                                               5

Buyer and the Sellers. The Preliminary Closing Statement shall be deemed final
for the purposes of this Section 1.5 upon (i) the sixtieth (60th) day after the
Buyer's receipt of the Preliminary Closing Statement, if the Buyer has not
notified the Sellers of a dispute prior to such time or (ii) the final
resolution of all disputes, as provided hereinabove, if the Buyer has timely
notified the Sellers of such a dispute.

                           (c) Upon the Preliminary Closing Statement's being
deemed final (the "Final Closing Statement") as provided in Section 1.5(b), an
adjustment to the Purchase Price shall be made as follows:

                                    (i) if the EBITDA (the "Closing EBITDA") as
shown in the Final Closing Statement exceeds DM33,550,000, the Purchase Price
shall be increased by an amount equal to the product of the amount by which the
Closing EBITDA exceeds DM32,025,000 times 8.1;

                                    (ii) if the Closing EBITDA is less than
DM27,450,000, the Purchase Price shall be reduced by an amount equal to the
product of the amount by which the Closing EBITDA is less than DM28,975,000
times 8.1; and

                                    (iii) if the Net Worth as shown in the Final
Closing Statement is less than DM17,804,370, the Purchase Price shall be reduced
by an amount equal to DM17,804,370 less the Net Worth as shown in the Final
Closing Statement.

                           (d) Within ten (10) days after the Preliminary
Closing Statement is deemed to be final as provided above, any increase in the
Purchase Price shall be paid by the Buyer to the Sellers, and any decrease in
the Purchase Price shall be 


                                                                               6

paid by the Sellers to the Buyer, with any payments to the Sellers being pro
rated among them in accordance with their respective percentage ownership of the
Shares; provided, however, that if the Buyer shall have timely objected to the
Preliminary Closing Statement in accordance with Section 1.5(b), then pending
resolution of the amounts or items subject to dispute, the Buyer, on the one
hand, or the Sellers, on the other hand, as the case may be, shall, within five
(5) days after the delivery by the Buyer of its written objection, pay to the
other the amount of any Purchase Price adjustment to the extent of any amounts
which are not subject to dispute. Any Purchase Price adjustment pursuant to this
Section 1.5 shall be paid in cash in the lawful currency of the Federal Republic
of Germany by wire transfer of immediately available funds pursuant to wire
transfer instructions which shall be provided by the party or parties entitled
to receive such cash, to the other party or parties and shall bear interest from
the Closing Date through the date of payment at an annual rate equal to the
three-month Frankfurt Interbank Offered Rate, in effect at the time of such
payment, plus one percent (1.0%).

                           (e) Notwithstanding anything to the contrary
contained herein, in no event shall the amount of any net increase or decrease
in the Purchase Price pursuant to this Section 1.5 exceed, in the aggregate,
DM100 million.

         2. Closing; Closing Date. The Closing of the sale and purchase of the
Shares contemplated hereby shall take place at the offices of Paul, Weiss,
Rifkind, Wharton & Garrison, at 10:00 a.m. local time, on November 17, 1998, or
such other time or date as the parties may mutually agree in writing, provided
that all of the conditions to the Closing set forth in Articles 7 and 8 have
been satisfied or waived by the party 


                                                                               7


entitled to waive the same. The time and date upon which the Closing occurs is
herein called the "Closing Date."

         3. Representations and Warranties of the Sellers as to the Company and
the Subsidiaries. The Sellers, jointly and severally, guarantee within the
meaning of an autonomous guarantee (EIGENSTANDIGES GARANTIEVERSPRECHEN), to NFO
and the Buyer as follows:

                  3.1 Due Incorporation and Authority. The Company is a
AKTIENGESELLSCHAFT (stock corporation) duly organized and incorporated, validly
existing and in good standing under the Laws of the Federal Republic of Germany
and has all requisite necessary corporate power and lawful authority to own,
lease and operate its properties and to carry on its business as now being and
heretofore conducted. The Company and each of its Subsidiaries is duly qualified
or licensed and in good standing to do business in each jurisdiction in which
the property owned, leased or operated by it or the nature of the business
conducted by it makes such qualification or licensing necessary, except where
the failure to be so duly qualified or licensed and in good standing would not,
in the aggregate, have a Material Adverse Effect.

                  3.2 Subsidiaries and Other Affiliates. Schedule 3.2.1 sets
forth the name and jurisdiction of organization of each corporation or other
entity (collectively, "Subsidiaries") in which the Company directly or
indirectly owns or has the power to vote shares of any capital stock or other
ownership interests having voting power to elect a majority of the directors of
such corporation, or other persons performing similar functions for such entity,
as the case may be. Each of the Subsidiaries is duly organized, 


                                                                               8

validly existing and in good standing under the laws of its jurisdiction of
organization and has the requisite power and lawful authority to own, lease and
operate its properties and to carry on its business as now being and heretofore
conducted. Except for the Subsidiaries and as set forth on Schedule 3.2.2,
neither the Company nor any Subsidiary owns, directly or indirectly, any
interest in any other person. Schedule 3.2.2 sets forth the percentage ownership
of the entities listed on Schedule 3.2.2 by the Company and the Subsidiaries.

                  3.3 Outstanding Capital Stock. The Company is authorized to
issue 2,000 shares of common stock, par value DM50 per share (the "Common
Stock"), of which all shares are bearer shares and are issued and outstanding.
All of the outstanding shares of Common Stock are owned by the Sellers, in the
respective amounts set forth on Schedule 1.3, free and clear of any Liens. Each
of the Sellers will surrender such shares pursuant to Section 1.3 and will
transfer title to such shares pursuant to Section 1.4 free and clear of any
Liens. The authorized, issued and outstanding shares of capital stock or other
ownership interests of each Subsidiary are set forth on Schedule 3.3. All issued
and outstanding capital stock or other ownership interests of each Subsidiary is
owned by the Company, or the Subsidiaries of the Company, as set forth on
Schedule 3.3, free and clear of any Lien. Except as set forth on Schedule 3.3,
all of the outstanding shares of capital stock of the Company and the
Subsidiaries are duly authorized and validly issued, fully paid and
nonassessable.

                  3.4 Options or Other Rights. Except as set forth on Schedule
3.4, there is no outstanding right, subscription, warrant, call, unsatisfied
preemptive right, 


                                                                               9

option or other agreement of any kind to purchase or otherwise to receive from
the Company, any of the Subsidiaries or any Seller any shares of the capital
stock or any other security of the Company or any of the Subsidiaries, and there
is no outstanding security of any kind of the Company or any of the Subsidiaries
convertible into capital stock.

                  3.5 Charter Documents and Corporate Records. The Sellers have
heretofore delivered or made available to NFO and the Buyer true and complete
certified excerpts of the HANDELSREGISTER (commercial register kept by the local
German courts) and, where applicable, corporate certificates (certified by the
respective corporation's secretary or an assistant secretary, or any other such
person competent to so certify), or comparable instruments, of the Company and
each of the Subsidiaries as in effect on the date hereof. Where applicable, the

Agreement. The Sellers agree, jointly and severally, to indemnify and hold
harmless NFO, the Buyer, the Company and the Subsidiaries from any Claim or
demand for commission or other compensation by any Broker claiming to have been
employed by or on behalf of the Company, any of the 


                                                                              25

Subsidiaries or any of the Sellers, and to bear the cost of legal expenses
incurred in defending against any such claim. Each of NFO and the Buyer
represents and warrants to the Sellers that no Broker other than William Blair &
Company has acted on behalf of NFO or the Buyer in connection with this
Agreement or the transactions contemplated hereby, and that, other than to
William Blair & Company, there are no brokerage commissions, finders' fees or
similar fees or commissions payable in connection therewith based on any
agreement, arrangement or understanding with NFO or the Buyer, or any action
taken by NFO or the Buyer. Each of NFO and the Buyer agrees to indemnify and
hold harmless the Company, the Subsidiaries and the Sellers from any Claim or
demand for commission or other compensation by any Broker (including, without
limitation, William Blair & Company) claiming to have been employed by or on
behalf of NFO or the Buyer, and to bear the cost of legal expenses incurred in
defending against any such claim.

                  6.6 Related Parties. The Sellers shall, prior to the Closing,
(a) pay or cause to be paid to the Company or each of the Subsidiaries, as the
case may be, all amounts owed to the Company or such Subsidiary by any of the
Sellers or any affiliate of any of the Sellers and (b) cause the Company and
each of the Subsidiaries to pay back to the Sellers or to any affiliate of the
Sellers the debts set forth on Schedule 6.6. At and as of the Closing, any debts
of the Company or any of the Subsidiaries owed to any of the Sellers or to any
affiliate of any of the Sellers shall be canceled, except those debts owed to
any Seller in respect of his or her employment with the Company or any of the
Subsidiaries and incurred in the ordinary course of business.


                                                                              26

                  6.7 Termination of Agreements. The Sellers shall, prior to the
Closing, terminate or cause to be terminated all Contracts between the Company
or a Subsidiary, on the one hand, and a Seller or any affiliate of a Seller, on
the other hand, except for such contracts set forth on Schedule 6.7, and the
Company or such Subsidiary, as the case may be, shall retain no obligations
under such terminated Contracts.

                  6.8 Supervisory Board. To the extent not already paid prior to
the Closing, following the Closing, NFO shall cause the Company to pay each
member of the Company's supervisory board compensation for the fiscal year ended
September 30, 1998 in an amount equal to his or her compensation for the fiscal
year ended September 30, 1997, which amounts were DM20,000 for the chairman,
DM15,000 for the deputy chairman and DM10,000 for each of the supervisory
board's other four members.

                  6.9 Suits Against Certain Stockholders. Equita and Dr. Lena-
Renate Ernst hereby covenant and agree that neither of them will sue, or file or
institute any claim, action or proceeding against or involving, Dr. Hartmut
Kiock or Werner Hampf, or both, arising out of this Agreement or the operation
of the Company or any of the Subsidiaries, other than suits, claims, actions or
proceedings to obtain Dr. Kiock's and Mr. Hampf's proportionate share of any
indemnification obligations pursuant to Article 11 of this Agreement.
Notwithstanding the foregoing, nothing contained herein shall preclude Equita or
Dr. Ernst from suing Dr. Kiock or Mr. Hampf, or both, to the extent that prior
to the Closing Date Dr. Kiock or Mr. Hampf, or both, willingly and fraudulently
concealed information from Dr. Ernst and/or Equita that was necessary to 


                                                                              27

make the representations or warranties of the Sellers in this Agreement not
materially false or misleading.

                  6.10 Further Assurances. Each of the parties shall execute
such documents and take such further actions as may be reasonably required or
desirable to carry out the provisions of this Agreement and the transactions
contemplated hereby, including, without limitation, the Sellers using their
reasonable best efforts to promptly provide to NFO and the Buyer all information
required in connection with appropriate filings and submissions with the
BUNDESKARTELLAMT (Federal Cartel Office).

                  6.11 Employment Agreements. Each of Dr. Hartmut Kiock and
Werner Hampf hereby covenant and agree that they will terminate their existing
employment agreements with the Company and enter into new employment agreements
with the Company upon the consummation of the acquisition of the Company by the
Buyer. The terms of such employment agreements will be substantially consistent
with the terms of the draft agreements previously reviewed by NFO, on the one
hand, and by Dr. Hartmut Kiock and Werner Hampf, on the other hand.

                  6.12 Supervisory Board Resignations. The Sellers shall cause
the members of the Company's supervisory board (AUFSICHTSRATSMITGLIEDER) to
resign therefrom or shall withdraw such members therefrom, in either case at or
prior to the Closing. The Sellers shall indemnify the Company from and against
any claims or causes of action by such former supervisory board members except
in respect of any claims for the payments to be made pursuant to Section 6.8
hereof.



                                                                              28

         7. Conditions Precedent to the Obligation of NFO and the Buyer to
Close. The obligation of NFO and the Buyer to enter into and complete the
Closing is subject, at the option of NFO and the Buyer acting in accordance with

                  7.2 HSR Act Filing. Any person required in connection with the

expired or been terminated.

                  7.3 No Claims. No Claims shall be pending or, to the knowledge
of NFO, the Buyer, the Company, any of the Subsidiaries or any of the Sellers,

                                                                              29

the United States Department of Justice or the Federal Trade Commission in
connection with antitrust regulations) to restrain or prohibit, or to obtain
damages or a discovery order in respect of, this Agreement or the consummation
of the transactions contemplated hereby or which has had or may have, in the
reasonable judgment of NFO or the Buyer, a Material Adverse Effect.

                  7.4 Due Diligence Investigation. The results of the due

terminated pursuant to Section 6.7 and of the release of any obligations under
such Contracts of the Company or any of the Subsidiaries.

         8. Conditions Precedent to the Obligation of the Sellers to Close. The
obligation of the Sellers to enter into and complete the Closing is subject, at
the option of the Sellers acting in accordance with the provisions of Article 12
with respect to termination of this Agreement, to the fulfillment on or prior to

waived by the Sellers:

                  8.1 Representations and Covenants. The representations and
warranties of NFO and the Buyer contained in this Agreement shall be true on and

the Buyer, to the foregoing effect.

                  8.2 HSR Act Filing. Any person required in connection with the
transactions contemplated by this Agreement to file a notification and report
form in compliance with the HSR Act shall have filed such form and the

                  8.3 No Claims. No Claims shall be pending or, to the knowledge
of NFO, the Buyer, the Company, any of the Subsidiaries or any of the Sellers,
threatened, before any Governmental Body (including investigations instituted by
the United States Department of Justice or the Federal Trade Commission in
connection with antitrust regulations) to restrain or prohibit, or to obtain
damages or a discovery order in respect of, this Agreement or the consummation
of the transactions contemplated hereby.

         9. Non-Competition/Non-Solicitation Covenant.

                  9.1 Non-Compete/Non-Solicitation. Following the Closing, for a
period of four years following the Closing Date, each such Seller shall not,
directly or indirectly, in any geographical area or in any foreign country in
which the Company or any of the Subsidiaries engages in business on the Closing
Date (which areas and countries include, without limitation, the Federal
Republic of Germany, the European Union, the United States of America and
Canada), in any form or manner:


                                                                              31


                           (a) own, manage, control, participate in, consult
with, render services for, or in any manner engage in any business competing
with the market research businesses of NFO and the Buyer and the businesses of
the Company or their respective Subsidiaries as such businesses exist or are in
process on the Closing Date; provided, however, that each such Seller may be a
passive owner of not more than 5% of the outstanding stock of any class of a
corporation which is publicly traded, so long as such Seller has no active
participation in the business of such corporation; or

                           (b) (i) induce or attempt to induce any employee of
NFO, the Buyer, the Company or any of their respective subsidiaries to leave the
employ thereof or (ii) induce or attempt to induce any customer, supplier,
licensee or other business relation of NFO, the Buyer, the Company or any of
their respective Subsidiaries to cease doing business with NFO, the Buyer, the
Company or any such Subsidiary, or in any way interfere with the relationship
between any such customer, supplier, licensee or business relation and NFO, the
Buyer, the Company or any of their respective Subsidiaries.

                  9.2 Rights and Remedies Upon Breach. If a Seller breaches, or
threatens to commit a breach of, any of the provisions of Section 9.1(a) (the
"Restrictive Covenants"), NFO and the Buyer shall have the following rights and
remedies, each of which rights and remedies shall be independent of the other
and severally enforceable, and all of which rights and remedies shall be in
addition to, and not in lieu of, any other rights and remedies available to NFO
and the Buyer under law or in equity:



                                                                              32

                           (a) Specific Performance. The right and remedy to
have the Restrictive Covenants specifically enforced by any court having equity
jurisdiction, it being acknowledged and agreed that any such breach or
threatened breach will cause irreparable injury to NFO and the Buyer and that
money damages will not provide adequate remedy to NFO or the Buyer; and

                           (b) Accounting. The right and remedy to require a
Seller to account for and pay over to NFO or the Buyer all compensation,
profits, monies, accruals, increments or other benefits derived or received by
such Seller as the result of any transactions constituting a breach of any of
the Restrictive Covenants, and such Seller shall account for and pay over such
benefits to NFO or the Buyer.

                  9.3 Severability of Covenants. If any court determines that
any of the Restrictive Covenants, or any part thereof, is invalid or
unenforceable, the remainder of the Restrictive Covenants shall not thereby be
affected and shall be given full effect, without regard to the invalid portions.

                  9.4 Blue-Pencilling. If any court determines that any of the
Restrictive Covenants, or any part thereof, is unenforceable because of the
duration of such provision or the area covered thereby, such court shall have
the power to reduce the duration or area of such provision and, in its reduced
form, such provision shall then be enforceable and shall be enforced.

                  9.5 Enforceability in Jurisdictions. The parties intend to and
hereby confer jurisdiction to enforce the Restrictive Covenants upon the courts
of any jurisdiction within the geographical scope of such covenants. If the
courts of any one or 


                                                                              33

more of such jurisdictions hold the Restrictive Covenants wholly unenforceable
by reason of the breadth of such scope or otherwise, it is the intention of the
parties that such determination not bar or in any way affect NFO's or the
Buyer's right to the relief provided above in the courts of any other
jurisdiction within the geographical scope of such covenants, as to breaches of
such covenants in such other respective jurisdictions, such covenants as they
relate to each jurisdiction being, for this purpose, severable into diverse and
independent covenants.

         10. Survival of Representations and Warranties of the Sellers After
Closing. Notwithstanding any right of NFO and the Buyer to investigate fully the
affairs of the Company and the Subsidiaries and any right of the Sellers to
investigate fully the affairs of NFO and notwithstanding any knowledge of facts
determined or determinable by NFO, the Buyer or the Sellers pursuant to such
investigation or right of investigation, NFO, the Buyer and the Sellers have the
right to rely fully upon the representations, warranties, covenants and
agreements contained in this Agreement or in any Documents delivered pursuant to
this Agreement. All such representations, warranties, covenants and agreements
shall survive the execution and delivery of this Agreement and the Closing
hereunder. Except for those representations and warranties in Sections 3.3, 3.4,
4.1 and 4.2 (all of which representations and warranties shall terminate and
expire ten years after the Closing Date), all representations and warranties
(but not covenants or indemnification obligations pursuant to Section 11)
contained in this Agreement shall terminate and expire on February 10, 2001. The
indemnification obligations pursuant to 


                                                                              34

Sections 11.1(y) and (z) shall terminate and expire 90 days after the expiration
of the relevant statute of limitations.

         11. Indemnification.

                  11.1 Obligation of the Sellers To Indemnify. Subject to the
limitations contained in Article 10 and Section 11.4, from and after the Closing
Date the Sellers shall be jointly and severally liable to, and shall indemnify,
defend and hold harmless the Buyer, NFO and the Company (and any of their
directors, officers, partners, employees, agents and affiliates) (each, an "NFO
Indemnified Party") from and against all claims, losses, liabilities, damages,
deficiencies, costs or expenses (including interest, penalties and reasonable
fees of attorneys and disbursements (collectively, "Losses") (which, for the
purposes hereof, shall also include the reasonable fees of attorneys and
disbursements incurred by an NFO Indemnified Party in bringing a claim under
this Agreement, prosecuting its rights of indemnity in respect of such claim and
collecting any amounts awarded upon such claim) suffered, sustained or incurred
or required to be paid by any such person due to, based upon, arising out of or
otherwise in respect of (x) any inaccuracy in or any breach of any
representation, warranty, covenant or agreement of the Sellers contained in this
Agreement or any certificate required to be delivered in connection therewith,
(y) 50% of any Loss resulting from the disallowance of the allocation of step up
from the acquisition costs of Infratest Burke AG Holding in 1995 for trade tax
purposes for the period ending on the Closing Date, and (z) 50% of any Loss
(income tax, trade tax or otherwise) resulting from the transfer of
participations in non-German entities to Infratest Burke International GmbH
Holding in fiscal year 1995/96; 


                                                                              35

provided, however, that the Sellers shall not be liable for indemnification
pursuant to clause (x) of this Section 11.1 in respect of any individual Loss
that is less than DM25,000.

                  11.2 Obligation of NFO to Indemnify. Subject to the
limitations contained in Article 10 and Section 11.4, from and after the Closing
Date the Buyer and NFO shall be jointly and severally liable to, and shall,
indemnify, defend and hold harmless each Seller (each, a "Seller Indemnified
Party") from and against all Losses (which, for the purposes hereof, shall also
include the reasonable fees of attorneys anddisbursements incurred by a Seller
Indemnified Party in bringing a claim under this Agreement, prosecuting its
rights of indemnity in respect of such claim and collecting any amounts awarded
upon such claim) suffered, sustained or incurred or required to be paid by any
such person due to, based upon, arising out of or otherwise in respect of any
inaccuracy in or breach of any representation, warranty, covenant or agreement
of the Buyer or NFO contained in this Agreement or any certificate required to
be delivered by NFO pursuant thereto.

                  11.3 Notice to Indemnifying Party.

                           (a) If either an NFO Indemnified Party, on the one
hand, or any Seller Indemnified Party, on the other hand, as the case may be
(the "Indemnitee"), receives written notice of any third party claim or
potential claim or the commencement of any action or proceeding which could give
rise to an obligation on the part of any Seller, on the one hand, or the Buyer
or NFO, on the other hand, as the case may be, to provide indemnification (the
"Indemnifying Party") pursuant to Section 11.1 


                                                                              36

or 11.2, the Indemnitee shall promptly give the Indemnifying Party notice
thereof (the "Indemnification Notice"); provided, that the failure to give the
Indemnification Notice promptly shall not impair the Indemnitee's right to
indemnification in respect of such claim, action or proceeding unless, and only
to the extent that the lack of prompt notice adversely affects the ability of
the Indemnifying Party to defend against or diminish the Losses arising out of
such claim, action or proceeding. Delivery of the Indemnification Notice shall
be a condition precedent to any liability of the Indemnifying Party under the
provisions for indemnification contained in this Agreement. The Indemnification
Notice shall contain factual information (to the extent known to the Indemnitee)
describing the asserted claim in reasonable detail and shall include copies of
any notice or other document received form any third party in respect of any
such asserted claim. The Indemnifying Party shall have the right to assume the
defense of a third party claim or suit described in this Section 11.3 at its own
cost and expense and with counsel of its own choosing; provided, however, that
the Indemnifying Party acknowledges in writing (at the time it elects to assume
the defense of such claim or suit, which shall be not later than 30 days after
the date of the Indemnification Notice) its obligation under this Section 11.3
to indemnify the Indemnitee with respect to such claim or suit; such counsel is
reasonably satisfactory to the Indemnitee; the Indemnitee is kept fully informed
of all developments and is furnished copies of all papers; the Indemnitee is
given the opportunity, at its option, to participate at its own cost and expense
and with counsel of its own choosing (which shall be reasonably satisfactory to
the Indemnifying Party) in the defense of such claim or suit; and the
Indemnifying Party diligently prosecutes the defense of such claim


                                                                              37

or suit. In the event that all of the conditions of the foregoing provision are
not satisfied, the Indemnitee shall have the right, without impairing any of its
rights to indemnification as provided herein, to assume and control the defense
of such claim or suit and to settle such claim or suit. No settlement of any
such third party claim or suit shall be made by the Indemnifying Party without
the prior written consent of the Indemnitee (which shall not be unreasonably
withheld). No settlement of any such third party claim or suit shall be made by
the Indemnitee if the Indemnifying Party shall have assumed the defense thereof
and shall be in compliance with its obligations with respect thereto as set
forth above in this Section 11.3. If the Indemnifying Party chooses to defend
any claim, the Indemnitee shall make available to the Indemnifying Party, any
books, records or other documents within its control that are necessary or
appropriate for such defense. Notwithstanding the foregoing, the Indemnitee
shall have the right to employ separate counsel at the Indemnifying Party's
expense and to control its own defense of such asserted liability if in the
reasonable opinion of counsel to such Indemnitee (i) there are or may be legal
defenses available to such Indemnitee or to other Indemnitees that are different
from or additional to those available to the Indemnifying Party, or (ii) a
conflict or potential conflict exists between the Indemnifying Party and such
Indemnitee that would make such separate representation advisable.

                           (b) If any NFO Indemnified Party or any Seller
Indemnified Party, as the case may be, has a claim (or potential claim) in
respect of any Loss based upon, arising out of or otherwise in respect of a
breach of any representation, warranty, covenant or agreement contained herein
or in any certificate required to be 


                                                                              38

delivered in connection herewith which does not relate to a claim, suit or
proceeding by a third party, then such NFO Indemnified Party or Seller
Indemnified Party, as the case may be, shall send to the Sellers or the Buyer,
respectively, a written notice describing the facts or circumstances with
respect to the subject matter of such claim (or potential claim). Any such
notice must be received by the Sellers or the Buyer, as the case may be, on or
prior to the date on which the representation or warranty on which such claim
(or potential claim) or action or proceeding is based ceases to survive as set
forth in Article 10, irrespective of whether the subject matter of such claim
(or potential claim), action or proceeding shall have occurred before or will
occur after such date.

                  11.4 Limitations on Indemnification. Anything in Section 11.1
to the contrary notwithstanding, no indemnification payment shall be made
pursuant to Section 11.1 except to the extent that the amounts that would
otherwise be payable under Section 11.1 taken together would aggregate at least
DM2,400,000 (the "Minimum Amount"); provided, however, that the foregoing
exception shall not apply to indemnification in respect of any breach of the
representations and warranties contained in Sections 3.13, 3.16 or Article 4 or
any indemnification pursuant to clauses (y) or (z) of Section 11.1.
Notwithstanding anything to the contrary contained herein, any Loss in respect
of indemnification pursuant to clause (x) of Section 11.1 that is less than
DM25,000 shall not be counted when determining whether the Minimum Amount has
been reached; provided, however, that the full amount of any Loss in respect of
indemnification pursuant to clause (x) of Section 11.1 that equals or exceeds
DM25,000 shall be counted when determining whether the Minimum Amount has been
reached. 


                                                                              39

After the Minimum Amount has been met all amounts payable under Section 11.1
(including the Minimum Amount) shall be payable by the Sellers until the amounts
paid by the Sellers shall equal DM100 million (the "Maximum Amount"); provided,
however, that the Maximum Amount shall be increased by 50% of the amount of any
Purchase Price adjustment paid to the Sellers pursuant to Section 1.5 of this
Agreement. For purposes of this Article 11, the amount of any Loss and the
amount of any indemnification payment to be made by any party shall be
determined (i) without deducting therefrom any Tax benefit obtained following
the date hereof by reason of the deductibility for Tax purposes of any damage,
loss or payment giving rise to any such Loss or indemnification payment, (ii)
without including therein an increase or "gross-up" for any Tax liability that
may be incurred following the date hereof by reasons of the inclusion in income
of, or by reason of a reduction in tax basis as a result of, any indemnification
payment received hereunder, but (iii) in case an Indemnifying Party is liable to
indemnify an NFO Indemnified Party from Tax liabilities for periods prior to the
Closing Date, by deducting therefrom any Tax benefits (but net of interest and
penalties) obtained by the NFO Indemnified Party for periods following the
Closing Date which result from the same event, circumstance or state of facts
causing such Tax payment; provided, however, that in case such Tax benefit will
be obtained later than the indemnification payment has to be made, the
Indemnified Party will be reimbursed by the NFO Indemnified Party only at the
time the benefit actually accrues to the NFO Indemnified Party.

binding upon and inure to the benefit of the parties and their respective
successors and legal representatives. This Agreement is not assignable except by

                  13.9 Counterparts. This Agreement may be executed by the
parties hereto in separate counterparts, each of which when so executed and
delivered shall be an original, but all such counterparts shall together

                  13.12 Interpretation. The parties acknowledge and agree that:
(i) each party and its counsel reviewed and negotiated the terms and provisions
of this Agreement and have contributed to its revision; (ii) the rule of

as to all parties hereto, regardless of which party was generally responsible
for the preparation of this Agreement.

                  13.13 Severability of Provisions.

                           (a) If any provision or any portion of any provision
of this Agreement shall be held invalid or unenforceable, the remaining portion
of such provision and the remaining provisions of this Agreement shall not be
affected thereby.

                           (b) If the application of any provision or any
portion of any provision of this Agreement to any person or circumstance shall
be held invalid or unenforceable, the application of such provision or portion
of such provision to persons or circumstances other than those as to which it is
held invalid or unenforceable shall not be affected thereby.


                                                                              52
