                  (i) the Corporation hereby agrees that on or prior to the
         Distribution Date or as soon as reasonably practicable thereafter,
         subject to the limitations set forth in this Section 2.1(f), it will,
         and it will cause each member of the Moody's Group to, assign, transfer
         and convey to the appropriate member of the New D&B Group all of the
         Corporation's or such member of the Moody's Group's respective right,
         title and interest in and to any and all New D&B Contracts;

                  (ii) New D&B hereby agrees that on or prior to the
         Distribution Date or as soon as reasonably practicable thereafter,
         subject to the limitations set forth in this Section 2.1(f), it will,
         and it will cause each member of the New D&B Group to, assign, transfer
         and convey to the Corporation or the appropriate member of the Moody's

         right, title and interest in and to any and all Moody's Contracts;

                  (iii) subject to the provisions of this Section 2.1(f), any

         Subsidiaries is a party that inures to the benefit of both the Moody's
         Business and the New D&B Business shall be assigned in part so that
         each party shall be entitled to the rights and benefits inuring to its
         business under such agreement;

                  (iv) the assignee of any agreement assigned, in whole or in

         (f)(iii), such Assignee's related portion of such obligations as
         determined in accordance with the terms of the relevant agreement,
         where determinable on the face thereof, and otherwise as determined in
         accordance with the practice of the parties prior to the Distribution;
         and

                  (v) notwithstanding anything in this Agreement to the
         contrary, this Agreement shall not constitute an agreement to assign
         any agreement, in whole or in part, or any rights thereunder if the

         consent is obtained, or if an attempted assignment thereof would be
         ineffective or would adversely affect the rights of any party hereto so
         that the intended Assignee would not, in fact, receive all such rights,
         the parties will cooperate with each other in any arrangement designed
         to provide for the intended Assignee the benefits of, and to permit the
         intended Assignee to assume liabilities under, any such agreement.

                  (b) Notwithstanding anything to the contrary herein or in any
Ancillary Agreement, the Corporation agrees to promptly remit to New D&B any
amounts representing prepayments or advances of expenses or payables of the

                  (c) The Corporation agrees to promptly remit to New D&B any
amounts received by any member of the Moody's Group (whether before, on or after

contribute cash to, or assume indebtedness from, New D&B or the Corporation, as
the case may be, in an amount determined in accordance with Schedule 2.3 hereto

New D&B will prepare and deliver to the Corporation a proposed calculation of
the Intercompany Transfer (the "Statement"). The Corporation shall be entitled
to reasonable access during normal business hours to the relevant records and
working papers prepared by or for New D&B to review the Statement. If the
Corporation believes that the Statement has not been prepared in accordance with
Schedule 2.3, it shall, within five business days after receipt of the
Statement, give written notice (the "Objection") to New D&B, setting forth the
basis of the Objection in reasonable detail

<PAGE>   31
                                                                              26

and the adjustments to the Statement which the Corporation believes should be
made. Failure to so notify New D&B shall constitute acceptance and approval of
the Statement. If New D&B agrees that any change proposed by the Corporation is
appropriate, the change shall be made to the Statement. If all or any portion of
the proposed change is disputed by New D&B, then the Corporation and New D&B
shall negotiate in good faith to resolve such dispute as expeditiously as
possible. If, after a period of five business days following the date on which
the Corporation gives New D&B notice of any such proposed change, any such
proposed change still remains disputed, then _______________ or another
nationally recognized accounting firm mutually agreed by the Corporation and New
D&B (the "Accounting Firm"), shall be engaged to resolve any remaining disputes.
The Accounting Firm shall determine, based solely on presentations by the
Corporation and New D&B and not by independent review, only those issues still
in dispute. In resolving any disputed item the Accounting Firm (x) shall be
bound by the provisions of Schedule 2.3 and (y) may not assign a value to any
item greater than the greatest value for such item claimed by either party or
less than the smallest value for such item claimed by either party. The
Accounting Firm's determination shall be made within thirty (30) days following
the date on which the dispute is submitted, shall be set forth in a written
statement delivered to the Corporation and New D&B that includes a definitive
calculation of the Intercompany Transfer and shall be final, binding and
conclusive. The Corporation and New D&B shall share the fees and any expenses of
the Accounting Firm equally.

                  (d) If the amount of the Intercompany Transfer, as finally
determined in accordance with paragraph (c) above, is such that, after giving
effect to the Estimated Intercompany Transfer, the Corporation is required to
make a payment to New D&B, then the Corporation shall make such payment to New
D&B, together with interest thereon from the Distribution Date to the date of
payment at the "base rate" of _____________ or any successor thereto from time
to time announced in the City of New York (the "Applicable Rate"), by wire
transfer of immediately available funds to such account or accounts as New D&B
previously shall have specified in writing to the Corporation.

                  (e) If the amount of the Intercompany Transfer, as finally
determined in accordance with paragraph (c) above, is such that, after giving
effect to the Estimated Intercompany Transfer, New D&B is required to make a
payment to the Corporation, then New D&B shall make such payment to the
Corporation, together with interest thereon from the Distribution Date to the
date of payment at the Applicable Rate, by wire transfer of immediately
available funds to such account or accounts as the Corporation previously shall
have specified in writing to New D&B.

                  SECTION 2.4. Assumption and Satisfaction of Liabilities.
Except as otherwise specifically set forth in any Ancillary Agreement, and
subject to Section 2.3 hereof, from and after the Effective Time, (i) the

pay, perform and discharge all Moody's Liabilities and (ii) New D&B shall, and

form reasonably satisfactory to such party, as may be reasonably necessary to
evidence the assumption of any Liabilities hereunder.

                                                                              27

                  SECTION 2.5. Resignations. (a) Subject to Section 2.5(b), the
Corporation and Moody's shall use all reasonable efforts to cause all their
employees to resign or be terminated, effective as of the close of business on
the Distribution Date, from all positions as officers or directors of any member
of the New D&B Group in which they serve, and New D&B shall use all reasonable
efforts to cause all its employees to resign or be terminated, effective as of
the close of business on the Distribution Date, from all positions as officers
or directors of the Corporation or any members of the Moody's Group in which
they serve.

                  (b) No person shall be required by any party hereto to resign
from any position or office with another party hereto if such person is
disclosed in the Information Statement as the person who is to hold such
position or office following the Distribution.

                  SECTION 2.6. Further Assurances. In case at any time after
the Effective Time any further action is reasonably necessary or desirable to
carry out the purposes of this Agreement and the Ancillary Agreements, the
proper officers of each party to this Agreement shall take all such necessary
action. Without limiting the foregoing, the Corporation and New D&B shall use
their commercially reasonable efforts promptly to obtain all consents and
approvals, to enter into all amendatory agreements and to make all filings and
applications that may be required for the consummation of the transactions
contemplated by this Agreement and the Ancillary Agreements, including, without
limitation, all applicable governmental and regulatory filings.

                  SECTION 2.7. Limited Representations or Warranties. Each of
the parties hereto agrees that no party hereto is, in this Agreement or in any
other agreement or document contemplated by this Agreement or otherwise, making
any representation or warranty whatsoever, as to title or value of Assets being
transferred. It is also agreed that, notwithstanding anything to the contrary
otherwise expressly provided in the relevant Conveyancing and Assumption
Instrument, all Assets either transferred to or retained by the parties, as the
case may be, shall be "as is, where is" and that (subject to Section 2.6) the
party to which such Assets are to be transferred hereunder shall bear the
economic and legal risk that such party's or any of the Subsidiaries' title to
any such Assets shall be other than good and marketable and free from
encumbrances. Similarly, each party hereto agrees that, except as otherwise
expressly provided in the relevant Conveyancing and Assumption Instrument, no
party hereto is representing or warranting in any way that the obtaining of any
consents or approvals, the execution and delivery of any amendatory agreements
and the making of any filings or applications contemplated by this Agreement
will satisfy the provisions of any or all applicable agreements or the
requirements of any or all applicable laws or judgments, it being agreed that
the party to which any Assets are transferred shall bear the economic and legal
risk that any necessary consents or approvals are not obtained or that any
requirements of laws or judgments are not complied with.

                  SECTION 2.8. Guarantees. (a) Except as otherwise specified in
any Ancillary Agreement, the Corporation and New D&B shall use their
commercially reasonable efforts to have, on or prior to the Distribution Date,

Moody's Group removed as guarantor of or obligor for any New D&B Liability,
including, without limitation, in respect of those guarantees set forth on

have, on or prior to the Distribution Date, or as soon as practicable
thereafter, any member of the New D&B Group removed as guarantor of or obligor
for any Moody's Liability, including, without limitation, in respect of those
guarantees set forth on Schedule 2.8(b) to the extent that they relate to
Moody's Liabilities.

                  (c) If the Corporation or New D&B is unable to obtain, or to
cause to be obtained, any such required removal as set forth in clauses (a) or
(b) of this Section 2.8, the applicable guarantor or obligor shall continue to
be bound as such and, unless not permitted by law or the terms thereof, the
relevant beneficiary shall or shall cause one of its Subsidiaries, as agent or
subcontractor for such guarantor or obligor to pay, perform and discharge fully
all the obligations or other liabilities of such guarantor or obligor thereunder
from and after the Distribution Date.

                  SECTION 2.9. Witness Services. At all times from and after
the Distribution Date, each of the Corporation and New D&B shall use their
commercially reasonable efforts to make available to the other, upon reasonable
written request, its and its Subsidiaries' officers, directors, employees and
agents as witnesses to the extent that (i) such persons may reasonably be
required in connection with the prosecution or defense of any Action in which
the requesting party may from time to time be involved and (ii) there is no
conflict in the Action between the requesting party and the Corporation or New
D&B as applicable. A party providing witness services to the other party under
this Section shall be entitled to receive from the recipient of such services,
upon the presentation of invoices therefor, payments for such amounts, relating
to disbursements and other out-of-pocket expenses (which shall be deemed to
exclude the costs of salaries and benefits of employees who are witnesses), as
may be reasonably incurred in providing such witness services.

                  SECTION 2.10. Certain Post-Distribution Transactions. (a) (i)
The Corporation shall comply and shall cause its Subsidiaries to comply with and
otherwise not take action inconsistent with each representation and statement
made to the Internal Revenue Service in connection with the request by the
Corporation for a ruling letter in respect of the Distribution as to certain tax
aspects of the Distribution, dated February 29, 2000, and three requests by the
Corporation for ruling letters in respect of certain internal restructuring
transactions related to the Distribution (the "Internal Restructuring
Transactions") as to certain tax aspects of such Internal Restructuring
Transactions, in each case dated April 28, 2000, and (ii) until two years after
the Distribution Date, the Corporation will cause Moody's to maintain its status
as a company engaged in the active conduct of a trade or business, as defined in
Section 355(b) of the Code, will continue to own stock of Moody's constituting
control (within the meaning of Section 368(c) of the Code) of Moody's and will
maintain at least ninety percent of the fair market value of the Corporation's
assets in stock and securities of Moody's and such other assets which, based on
an opinion of a law firm reasonably acceptable to New D&B, or a supplemental
ruling from the Internal Revenue Service, will not cause the Corporation or
Moody's to be in violation of the active business requirement under the holding
company test.

                  (b)(i) New D&B shall comply and shall cause its Subsidiaries
to comply with and otherwise not take action inconsistent with each
representation and statement made to the Internal Revenue Service in connection
with the request by the Corporation for a ruling letter in respect of the
Distribution as to certain tax aspects of the Distribution, dated February 29,
2000, and three requests by the Corporation for ruling letters in respect of the
Internal Restructuring Transactions as to certain tax aspects of such Internal
Restructuring Transactions, in each case dated April 28, 2000, and (ii) until
two years after the Distribution Date, New D&B will cause each of D&B Opco Inc.
and Dun & Bradstreet International, Ltd. ("DBI") to maintain its status as a
company engaged in the active conduct of a trade or business, as defined in
Section 355(b) of the Code, will continue to own stock in D&B Opco Inc. and DBI
constituting control (within the meaning of Section 368(c) of the Code) of D&B
Opco Inc. and DBI will maintain at least ninety percent of the fair market value
of New D&B's assets in stock and securities of D&B Opco Inc. and DBI and such
other assets which, based on an opinion of a law firm reasonably acceptable to
the Corporation, or a supplemental ruling from the Internal Revenue Service,
will not cause New D&B, D&B Opco Inc. or DBI to be in violation of the active
business requirement under the holding company test.

                  (c) The Corporation agrees that until two years after the
Distribution Date, it will not (i) merge or consolidate with or into any other
corporation, (ii) liquidate or partially liquidate, (iii) sell or transfer all
or substantially all of its assets (within the meaning of Rev. Proc. 77-37, 1977
- 2 C.B. 568) in a single transaction or series of related transactions, (iv)
redeem or otherwise repurchase any D&B Common Stock (other than as described in
Section 4.05(1)(b) of Rev. Proc. 96-30, 1996-1 C.B. 696), or (v) take any other
action or actions which in the aggregate would have the effect of causing or
permitting one or more persons to acquire directly or indirectly stock
representing a 50 percent or greater interest (within the meaning of Section
355(e) of the Code) in the Corporation, unless prior to taking such action the
Corporation has obtained (and provided to New D&B) a written opinion of a law
firm reasonably acceptable to New D&B, or a supplemental ruling from the
Internal Revenue Service, that such action or actions will not result in (i) the
Distribution failing to qualify under Section 355(a) of the Code or (ii) the New
D&B Common Stock failing to qualify as qualified property for purposes of
Section 355(c)(2) of the Code by reason of Section 355(e) of the Code.

                  (d) New D&B agrees that until two years after the Distribution
Date, it will not (i) merge or consolidate with or into any other corporation,
(ii) liquidate or partially liquidate, (iii) sell or transfer all or
substantially all of its assets (within the meaning of Rev. Proc. 77-37, 1977 -
2 C.B. 568) in a single transaction or series of related transactions, (iv)
redeem or otherwise repurchase any New D&B Common Stock (other than as described
in Section 4.05(1)(b) of Rev. Proc. 96-30, 1996-1 C.B. 696), or (v) take any
other action or actions which in the aggregate would have the effect of causing
or permitting one or more persons to acquire directly or indirectly stock
representing a 50 percent or greater interest (within the meaning of Section
355(e) of the Code) in New D&B, unless prior to taking such action New D&B has
obtained (and provided to the Corporation) a written opinion of a law firm
reasonably acceptable to the Corporation, or a supplemental ruling from the
Internal Revenue Service, that such action or actions will not result in (i) the
Distribution failing to qualify under Section 355(a) of the Code or

<PAGE>   35
                                                                              30

(ii) the New D&B Common Stock failing to qualify as qualified property for
purposes of Section 355(c)(2) of the Code by reason of Section 355(e) of the
Code.

                  (e) Notwithstanding anything to the contrary herein or in the
Tax Allocation Agreement, if the Corporation or New D&B (or any of their
respective Subsidiaries) fails to comply with any of its obligations under
Sections 2.10(a), 2.10(b), 2.10(c) or 2.10(d) above or takes or fails to take
any action on or after the Distribution Date, and such failure to comply, action
or omission contributes to a determination that (i) the Distribution fails to
qualify under Section 355(a) of the Code, (ii) the New D&B Common Stock fails to
qualify as qualified property for purposes of Section 355(c)(2) of the Code by
reason of Section 355(e) of the Code, or (iii) the Internal Restructuring
Transactions set forth in the three requests for ruling letters dated April 28,
2000 fail to qualify in any respect for the tax treatment sought in such
requests for ruling letters, that party shall indemnify and hold harmless the
other party and each member of the consolidated group of which the other party
is a member from and against any and all federal, state and local taxes,
including any interest, penalties or additions to tax, imposed upon or incurred
by such other party, any member of its group or any stockholder of either party
as a result of the failure of the Distribution to qualify under Section 355(a)
of the Code, the application of Section 355(e), or the failure to realize the
intended tax consequences of the Internal Restructuring Transactions. The
obligation of a party to indemnify the other party pursuant to the preceding
sentence shall not be affected by the delivery of any legal opinion or
supplemental ruling under Section 2.10(c) or Section 2.10(d), as the case may
be.

                  SECTION 2.11. Transfers Not Effected Prior to the
Distribution; Transfers Deemed Effective as of the Distribution Date. To the
extent that any transfers contemplated by this Article II shall not have been
consummated on or prior to the Distribution Date, the parties shall cooperate to
effect such transfers as promptly following the Distribution Date as shall be
practicable. Nothing herein shall be deemed to require the transfer of any
Assets or the assumption of any Liabilities which by their terms or operation of
law cannot be transferred; provided, however, that the parties hereto and their
respective Subsidiaries shall cooperate to seek to obtain any necessary consents
or approvals for the transfer of all Assets and Liabilities contemplated to be
transferred pursuant to this Article II. In the event that any such transfer of
Assets or Liabilities has not been consummated, from and after the Distribution
Date the party retaining such Asset or Liability shall hold such Asset in trust
for the use and benefit of the party entitled thereto (at the expense of the
party entitled thereto) or retain such Liability for the account of the party by
whom such Liability is to be assumed pursuant hereto, as the case may be, and
take such other action as may be reasonably requested by the party to whom such
Asset is to be transferred, or by whom such Liability is to be assumed, as the
case may be, in order to place such party, insofar as is reasonably possible, in
the same position as would have existed had such Asset or Liability been
transferred as contemplated hereby. As and when any such Asset or Liability
becomes transferable, such transfer shall be effected forthwith. The parties
agree that, as of the Distribution Date, each party hereto shall be deemed to
have acquired complete and sole beneficial ownership over all of the Assets,
together with all rights, powers and privileges incident thereto, and shall be
deemed to have assumed in accordance with the terms of this Agreement all of the
Liabilities, and all duties, obligations and responsibilities

<PAGE>   36
                                                                              31

incident thereto, which such party is entitled to acquire or required to assume
pursuant to the terms of this Agreement.

                  SECTION 2.12. Conveyancing and Assumption Instruments. In
connection with the transfers of Assets and the assumptions of Liabilities
contemplated by this Agreement, the parties shall execute or cause to be
executed by the appropriate entities the Conveyancing and Assumption Instruments
in substantially the form contemplated hereby for transfers to be effected
pursuant to New York law or the laws of one of the other states of the United
States or, if not appropriate for a given transfer, and for transfers to be
effected pursuant to non-U.S. laws, in such other form as the parties shall
reasonably agree, including the transfer of real property with deeds as may be
appropriate. The transfer of capital stock shall be effected by means of
delivery of stock certificates and executed stock powers and notation on the
stock record books of the corporation or other legal entities involved, or by
such other means as may be required in any non-U.S. jurisdiction to transfer
title to stock and, to the extent required by applicable law, by notation on
public registries.

                  SECTION 2.13. Ancillary Agreements. On or prior to the
Distribution Date, each of the Corporation and New D&B shall enter into, and/or
(where applicable) shall cause members of the Moody's Group or the New D&B
Group, as applicable, to enter into, the Ancillary Agreements and any other
agreements in respect of the Distribution reasonably necessary or appropriate in
connection with the transactions contemplated hereby and thereby.

                  SECTION 2.14. Intellectual Property. (a) Each of the parties
hereto acknowledges, recognizes and agrees that, after the Distribution Date, as
between the Corporation and New D&B, the Corporation (or another member of the
Moody's Group) shall own all right, title and interest in all Intellectual
Property that was created, designed, developed, invented, originated, obtained,
funded, and/or otherwise intended for the benefit or use, in each case,
exclusively or primarily for the conduct of the Moody's Business or in
connection with the Moody's Assets.

                  (b) Without limiting any obligation or liability of New D&B
under the Distribution Agreement or any Ancillary Agreement, each of the parties
hereto acknowledges, recognizes and agrees that, after the Distribution, as
between the Corporation and New D&B, New D&B (or another member of the New D&B
Group) shall own all right, title and interest in all Intellectual Property (i)
owned by the Corporation or any of its subsidiaries immediately prior to the
Distribution other than Intellectual Property described in Section 2.14(a) or
(ii) assigned to New D&B pursuant to the Intellectual Property Assignment.

                  (c) Each of the Corporation and New D&B acknowledges,
recognizes and agrees that, after the Distribution Date, as between the
Corporation and New D&B, (i) each party shall be sole owner of any and all
Intellectual Property that is created, designed, developed, invented,
originated, obtained and/or funded by it or on its behalf (including any new
improvements, enhancements, modifications or updates to, and/or derivative works
based upon any Intellectual Property existing as of the Distribution Date,
subject to the underlying rights therein), and (ii) absent any other agreement
to the contrary, each party's ownership, possession and use of any

<PAGE>   37
                                                                              32

Intellectual Property subsequent to the Distribution Date (including that
governed by the terms hereof) shall inure solely to such party's own benefit.

                  SECTION 2.15. Corporate Names. (a) Except as otherwise
specifically provided in any Ancillary Agreement:

                  (i) on or prior to the Distribution Date, the Corporation
         shall change its corporate and trade name to remove any reference to
         "Dun & Bradstreet" or any modification, abbreviation or derivative
         thereof, and shall effect such change with all appropriate Government
         Authorities or registries;

                  (ii) as soon as reasonably practicable after the Distribution
         Date but in any event within six months thereafter, the Corporation
         will, at its own expense, remove (and, if reasonably feasible, on an
         interim basis, cover up) any and all signage and other physical items
         located on any property or premises owned or used by it or its
         Subsidiaries (except property or premises to be shared with New D&B or
         its Subsidiaries after the Distribution) which bear or display the name
         "Dun & Bradstreet" or any modification, abbreviation or derivative
         thereof, either alone or in combination with any other name, mark or
         logo;

                  (iii) as soon as reasonably practicable after the Distribution
         Date but in any event within six months thereafter, the Corporation
         will, and will cause its Subsidiaries to, remove from all letterhead,
         envelopes, invoices and other communications or materials of any kind
         in any media, references to or displays of the name "Dun & Bradstreet"
         or any modification, abbreviation or derivative thereof, either alone
         or in combination with any other name, mark or logo (except that the
         Corporation shall not be required to take any such action with respect
         to materials in the possession of customers), and, after the
         Distribution Date, without the prior written consent of New D&B,
         neither the Corporation nor its Subsidiaries shall use, display,
         register, attempt to register (or assist or allow third parties to do
         same) the name "Dun & Bradstreet" or any modification, abbreviation or
         derivative thereof, either alone or in combination with any other name,
         mark or logo (except for the non-trademark use of the name as necessary
         in connection with information provided to Government Authorities and
         historical background required in the ordinary course of business);

                  (iv) as soon as reasonably practicable after the Distribution
         Date, but in any event within six months thereafter, the Corporation
         will cause its Subsidiaries to change their trade names and corporate
         names to remove any reference to "Dun & Bradstreet" or any
         modification, abbreviation or derivative thereof, and shall effect such
         change with all appropriate Government Authorities or registries;
         provided, however, that notwithstanding the foregoing, if the
         Corporation cannot timely comply herewith, due to regulatory or other
         circumstances beyond its reasonable control, it shall not breach this
         provision, if the Corporation uses reasonable efforts to effect timely
         compliance hereunder during such first six months, continues its
         good-faith efforts thereafter, and does effect such name change within
         nine months after the Distribution Date;

<PAGE>   38
                                                                              33

                  (v) notwithstanding (i) through (iv), nothing herein or in any
         Ancillary Agreement shall require the Corporation to take any action to
         remove any reference to D&B, including the name "Dun & Bradstreet" or
         any modification, abbreviation or derivative thereof, from any stock
         certificate relating to shares of D&B Common Stock outstanding on or
         prior to the Record Date; provided that from and after the Record Date,
         any newly issued stock certificates representing D&B Common Stock
         (which at the Effective Time will become Moody's Common Stock) shall
         not have any reference to D&B, including the name "Dun & Bradstreet"
         and any modification, abbreviation or derivative thereof.

                  (b) Except as otherwise specifically provided in any Ancillary
Agreement:

                  (i) as soon as reasonably practicable after the Distribution
         Date but in any event within six months thereafter, New D&B will, at
         its own expense, remove (and, if reasonably feasible, on an interim
         basis, cover up) any and all signage and other physical items located
         on any property or premises owned or used by it or its Subsidiaries
         (except property or premises to be shared with the Corporation or its
         Subsidiaries after the Distribution) which bear or display the name
         "Moody's" or any modification, abbreviation or derivative thereof,
         either alone or in combination with any other name, mark or logo;

                  (ii) as soon as reasonably practicable after the Distribution
         Date but in any event within six months thereafter, New D&B will, and
         will cause its respective Subsidiaries to, remove from all letterhead,
         envelopes, invoices and other communications or materials of any kind
         in any media, references to or displays of the name "Moody's" or any
         modification, abbreviation or derivative thereof, either alone or in
         combination with any other name, mark or logo (except that New D&B
         shall not be required to take any such action with respect to materials
         in the possession of customers), and, after the Distribution Date,
         without the prior written consent of the Corporation, neither New D&B
         nor its Subsidiaries shall use, display, register, attempt to register
         (or assist or allow third parties to do same) the name "Moody's" or any
         modification, abbreviation or derivative thereof, either alone or in
         combination with any other name, mark or logo (except for the
         non-trademark use of the name as necessary in connection with
         information provided to Government Authorities and historical
         background required in the ordinary course of business);

                  (iii) as soon as reasonably practicable after the Distribution
         Date but in any event within six months thereafter, New D&B will, and
         will cause its Subsidiaries to, change their trade names and corporate
         names to remove any reference to "Moody's" or any modification,
         abbreviation or derivative thereof, and shall effect such change with
         all appropriate Government Authorities or registries; provided,
         however, that notwithstanding the foregoing, if New D&B cannot timely
         comply herewith, due to regulatory or other circumstances beyond its
         reasonable control, it shall not breach this provision if New D&B uses
         reasonable efforts to effect timely compliance hereunder

<PAGE>   39
                                                                              34

         during such first six months, continues its good-faith efforts
         thereafter, and does effect such name change within nine months after
         the Distribution Date.

ARTICLE III. INDEMNIFICATION

                  SECTION 3.1. Indemnification by the Corporation. Except as
otherwise specifically set forth in any provision of this Agreement or of any
Ancillary Agreement, the Corporation shall indemnify, defend and hold harmless
the New D&B Indemnitees and Corporation Indemnitees from and against any and all
Indemnifiable Losses of the New D&B Indemnitees and Corporation Indemnitees
arising out of, by reason of or otherwise in connection with the Moody's
Liabilities or alleged Moody's Liabilities, including any breach by the
Corporation of any provision of this Agreement or any Ancillary Agreement.

                  SECTION 3.2. Indemnification by New D&B. Except as otherwise
specifically set forth in any provision of this Agreement or of any Ancillary
Agreement, New D&B shall indemnify, defend and hold harmless the Moody's
Indemnitees and Corporation Indemnitees from and against any and all
Indemnifiable Losses of the Moody's Indemnitees and Corporation Indemnitees
arising out of, by reason of or otherwise in connection with the New D&B
Liabilities or alleged New D&B Liabilities, including any breach by New D&B of
any provision of this Agreement or any Ancillary Agreement.

                  SECTION 3.3.  Procedures for Indemnification.

                  (a) Third Party Claims. If a claim or demand is made against a
Moody's Indemnitee, a New D&B Indemnitee or Corporation Indemnitee (each, an
"Indemnitee") by any person who is not a party to this Agreement (a "Third Party
Claim") as to which such Indemnitee is entitled to indemnification pursuant to
this Agreement, such Indemnitee shall notify the party which is or may be
required pursuant to Section 3.1 or Section 3.2 hereof to make such
indemnification (the "Indemnifying Party") in writing, and in reasonable detail,
of the Third Party Claim promptly (and in any event within 15 business days)
after receipt by such Indemnitee of written notice of the Third Party Claim;
provided, however, that failure to give such notification shall not affect the
indemnification provided hereunder except to the extent the Indemnifying Party
shall have been actually prejudiced as a result of such failure (except that the
Indemnifying Party shall not be liable for any expenses incurred during the
period in which the Indemnitee failed to give such notice). Thereafter, the
Indemnitee shall deliver to the Indemnifying Party, promptly (and in any event
within five business days) after the Indemnitee's receipt thereof, copies of all
notices and documents (including court papers) received by the Indemnitee
relating to the Third Party Claim.

                  If a Third Party Claim is made against an Indemnitee, the
Indemnifying Party shall be entitled to participate in the defense thereof and,
if it so chooses and acknowledges in writing its obligation to indemnify the
Indemnitee therefor, to assume the defense thereof with counsel selected by the
Indemnifying Party; provided that such counsel is not reasonably objected to by
the Indemnitee. Should the Indemnifying Party so elect to assume the defense of
a Third Party

<PAGE>   40
                                                                              35

Claim, the Indemnifying Party shall, within 30 days (or sooner if the nature of
the Third Party Claim so requires), notify the Indemnitee of its intent to do
so, and the Indemnifying Party shall thereafter not be liable to the Indemnitee
for legal or other expenses subsequently incurred by the Indemnitee in
connection with the defense thereof; provided, that such Indemnitee shall have
the right to employ counsel to represent such Indemnitee if, in such
Indemnitee's reasonable judgment, a conflict of interest between such Indemnitee
and such Indemnifying Party exists in respect of such claim which would make
representation of both such parties by one counsel inappropriate, and in such
event the fees and expenses of such separate counsel shall be paid by such
Indemnifying Party. If the Indemnifying Party assumes such defense, the
Indemnitee shall have the right to participate in the defense thereof and to
employ counsel, subject to the proviso of the preceding sentence, at its own
expense, separate from the counsel employed by the Indemnifying Party, it being
understood that the Indemnifying Party shall control such defense. The
Indemnifying Party shall be liable for the fees and expenses of counsel employed
by the Indemnitee for any period during which the Indemnifying Party has failed
to assume the defense thereof (other than during the period prior to the time
the Indemnitee shall have given notice of the Third Party Claim as provided
above). If the Indemnifying Party so elects to assume the defense of any Third
Party Claim, all of the Indemnitees shall cooperate with the Indemnifying Party
in the defense or prosecution thereof, including by providing or causing to be
provided, Records and witnesses as soon as reasonably practicable after
receiving any request therefor from or on behalf of the Indemnifying Party.

                  If the Indemnifying Party acknowledges in writing
responsibility for a Third Party Claim, then in no event will the Indemnitee
admit any liability with respect to, or settle, compromise or discharge, any
Third Party Claim without the Indemnifying Party's prior written consent;
provided, however, that the Indemnitee shall have the right to settle,
compromise or discharge such Third Party Claim without the consent of the
Indemnifying Party if the Indemnitee releases the Indemnifying Party from its
indemnification obligation hereunder with respect to such Third Party Claim and
such settlement, compromise or discharge would not otherwise adversely affect
the Indemnifying Party. If the Indemnifying Party acknowledges in writing
liability for a Third Party Claim, the Indemnitee will agree to any settlement,
compromise or discharge of a Third Party Claim that the Indemnifying Party may
recommend and that by its terms obligates the Indemnifying Party to pay the full
amount of the liability in connection with such Third Party Claim and releases
the Indemnitee completely in connection with such Third Party Claim and that
would not otherwise adversely affect the Indemnitee; provided, however, that the
Indemnitee may refuse to agree to any such settlement, compromise or discharge
if the Indemnitee agrees that the Indemnifying Party's indemnification
obligation with respect to such Third Party Claim shall not exceed the amount
that would be required to be paid by or on behalf of the Indemnifying Party in
connection with such settlement, compromise or discharge. If an Indemnifying
Party elects not to assume the defense of a Third Party Claim, or fails to
notify an Indemnitee of its election to do so as provided herein, such
Indemnitee may compromise, settle or defend such Third Party Claim.

                  Notwithstanding the foregoing, the Indemnifying Party shall
not be entitled to assume the defense of any Third Party Claim (and shall be
liable for the fees and expenses of counsel incurred by the Indemnitee in
defending such Third Party Claim) if the Third Party

<PAGE>   41
                                                                              36

Claim seeks an order, injunction or other equitable relief or relief for other
than money damages against the Indemnitee which the Indemnitee reasonably
determines, after conferring with its counsel, cannot be separated from any
related claim for money damages. If such equitable relief or other relief
portion of the Third Party Claim can be so separated from that for money
damages, the Indemnifying Party shall be entitled to assume the defense of the
portion relating to money damages.

                  (b) In the event of payment by an Indemnifying Party to any
Indemnitee in connection with any Third-Party Claim, such Indemnifying Party
shall be subrogated to and shall stand in the place of such Indemnitee as to any
events or circumstances in respect of which such Indemnitee may have any right
or claim relating to such Third-Party Claim against any claimant or plaintiff
asserting such Third-Party Claim. Such Indemnitee shall cooperate with such
Indemnifying Party in a reasonable manner, and at the cost and expense of such
Indemnifying Party, in prosecuting any subrogated right or claim.

                  (c) The remedies provided in this Article III shall be
cumulative and shall not preclude assertion by any Indemnitee of any other
rights or the seeking of any and all other remedies against any Indemnifying
Party.

                  SECTION 3.4. Indemnification Payments. Indemnification
required by this Article III shall be made by periodic payments of the amount
thereof during the course of the investigation or defense, as and when bills are
received or loss, liability, claim, damage or expense is incurred.

ARTICLE IV.  ACCESS TO INFORMATION

                  SECTION 4.1.  Provision of Corporate Records.

                  (a) Other than in circumstances in which indemnification is
sought pursuant to Article III (in which event the provisions of such Article
will govern), after the Distribution Date, upon the prior written request by New
D&B for specific and identified agreements, documents, books, records or files
(collectively, "Records") which relate to (x) New D&B or the conduct of the New
D&B Business up to the Effective Time, or (y) any Ancillary Agreement to which
the Corporation and New D&B are parties, as applicable, the Corporation shall
arrange, as soon as reasonably practicable following the receipt of such
request, for the provision of appropriate copies of such Records (or the
originals thereof if New D&B has a reasonable need for such originals) in the
possession or control of the Corporation or any of its Subsidiaries, but only to
the extent such items are not already in the possession or control of New D&B.

                  (b) Other than in circumstances in which indemnification is
sought pursuant to Article III (in which event the provisions of such Article
will govern), after the Distribution Date, upon the prior written request by the
Corporation for specific and identified Records which relate to (x) the
Corporation, Moody's or the conduct of the Moody's Business up to the Effective
Time, or (y) any Ancillary Agreement to which New D&B and the Corporation are

<PAGE>   42
                                                                              37

parties, as applicable, New D&B shall arrange, as soon as reasonably practicable
following the receipt of such request, for the provision of appropriate copies
of such Records (or the originals thereof if the Corporation has a reasonable
need for such originals) in the possession or control of New D&B or any of its
Subsidiaries, but only to the extent such items are not already in the
possession or control of the Corporation.

                  SECTION 4.2. Access to Information. Other than in
circumstances in which indemnification is sought pursuant to Article III (in
which event the provisions of such Article will govern), from and after the
Distribution Date, each of the Corporation and New D&B shall afford to the other
and its authorized accountants, counsel and other designated representatives
reasonable access during normal business hours, subject to appropriate
restrictions for classified, privileged or confidential information, to the
personnel, properties, books and records of such party and its Subsidiaries
insofar as such access is reasonably required by the other party and relates to
(x) such other party or the conduct of its business prior to the Effective Time
or (y) any Ancillary Agreement to which each of the party requesting such access
and the party requested to grant such access are parties.

                  SECTION 4.3. Reimbursement; Other Matters. Except to the
extent otherwise contemplated by any Ancillary Agreement, a party providing
Records or access to information to the other party under this Article IV shall
be entitled to receive from the recipient, upon the presentation of invoices
therefor, payments for such amounts, relating to supplies, disbursements and
other out-of-pocket expenses, as may be reasonably incurred in providing such
Records or access to information, as well as reimbursements on a per diem basis
for the reasonable costs of any personnel reasonably utilized by the party
providing Records or access to information under this Article IV to respond to
the relevant request.

                  SECTION 4.4. Confidentiality. Each of (i) the Corporation and
its Subsidiaries and (ii) New D&B and its Subsidiaries shall not use or permit
the use of (without the prior written consent of the other) and shall keep, and
shall cause its consultants and advisors to keep, confidential all information
concerning the other parties in its possession, its custody or under its control
(except to the extent that (A) such information has been in the public domain
through no fault of such party or (B) such information has been lawfully
acquired from other sources or independently developed by such party or (C) this
Agreement or any other Ancillary Agreement or any other agreement entered into
pursuant hereto permits the use or disclosure of such information) to the extent
such information (w) relates to or was acquired during the period up to the
Effective Time, (x) relates to any Ancillary Agreement, (y) is obtained in the
course of performing services for the other party pursuant to any Ancillary
Agreement, or (z) is based upon or is derived from information described in the
preceding clauses (w), (x) or (y), and each party shall not (without the prior
written consent of the other) otherwise release or disclose such information to
any other person, except such party's auditors and attorneys, unless compelled
to disclose such information by law, judicial or administrative process and such
party has used commercially reasonable efforts to consult with the other
affected party or parties prior to such disclosure and cooperates with the other
affected party, upon its request and at its expense, to obtain a protective
order or other similar remedy.

                                                                              38

                  SECTION 4.5. Privileged Matters. The parties hereto recognize
that legal and other professional services that have been and will be provided
on or prior to the Distribution Date have been and will be rendered for the
benefit of each of the Corporation, the members of the Moody's Group and the
members of the New D&B Group, and that each of the Corporation, the members of
the Moody's Group and the members of the New D&B Group should be deemed to be
the client for the purposes of asserting all privileges which may be asserted
under applicable law. To allocate the interests of each party in the information
as to which any party is entitled to assert a privilege, the parties agree as
follows:

                  (a) The Corporation shall be entitled, in perpetuity, to
control the assertion or waiver of all privileges in connection with privileged
information which relates solely to the Moody's Business, whether or not the
privileged information is in the possession of or under the control of the
Corporation or New D&B. The Corporation shall also be entitled, in perpetuity,
to control the assertion or waiver of all privileges in connection with
privileged information that relates solely to the subject matter of any claims
constituting Moody's Liabilities, now pending or which may be asserted in the
future, in any lawsuits or other proceedings initiated against or by the
Corporation, whether or not the privileged information is in the possession of
or under the control of the Corporation or New D&B.

                  (b) New D&B shall be entitled, in perpetuity, to control the
assertion or waiver of all privileges in connection with privileged information
which relates solely to the New D&B Business, whether or not the privileged
information is in the possession of or under the control of the Corporation or
New D&B. New D&B shall also be entitled, in perpetuity, to control the assertion
or waiver of all privileges in connection with privileged information which
relates solely to the subject matter of any claims constituting New D&B
Liabilities, now pending or which may be asserted in the future, in any lawsuits
or other proceedings initiated against or by New D&B whether or not the
privileged information is in the possession of or under the control of the
Corporation or New D&B.

                  (c) The parties hereto agree that they shall have a shared
privilege, with equal right to assert or waive, subject to the restrictions in
this Section 4.5, with respect to all privileges not allocated pursuant to the
terms of Sections 4.5(a) and (b). All privileges relating to any claims,
proceedings, litigation, disputes, or other matters which involve both the
Corporation and New D&B in respect of which both parties retain any
responsibility or liability under this Agreement shall be subject to a shared
privilege among them.

                  (d) No party hereto may waive any privilege which could be
asserted under any applicable law, and in which the other party hereto has a
shared privilege, without the consent of the other party, except to the extent
reasonably required in connection with any litigation with third-parties or as
provided in subsection (e) below. Consent shall be in writing, or shall be
deemed to be granted unless written objection is made within twenty (20) days
after notice upon the other party requesting such consent.

                  (e) In the event of any litigation or dispute between or among
any of the parties hereto, any party and a Subsidiary of another party hereto,
or a Subsidiary of one party hereto and

<PAGE>   44
                                                                              39

a Subsidiary of another party hereto, either such party may waive a privilege in
which the other party has a shared privilege, without obtaining the consent of
the other party, provided that such waiver of a shared privilege shall be
effective only as to the use of information with respect to the litigation or
dispute between the parties and/or their Subsidiaries, and shall not operate as
a waiver of the shared privilege with respect to third parties.

                  (f) If a dispute arises between or among the parties hereto or
their respective Subsidiaries regarding whether a privilege should be waived to
protect or advance the interest of any party, each party agrees that it shall
negotiate in good faith, shall endeavor to minimize any prejudice to the rights
of the other parties, and shall not unreasonably withhold consent to any request
for waiver by another party. Each party hereto specifically agrees that it will
not withhold consent to waiver for any purpose except to protect its own
legitimate interests.

                  (g) Upon receipt by any party hereto or by any Subsidiary
thereof of any subpoena, discovery or other request which arguably calls for the
production or disclosure of information subject to a shared privilege or as to
which another party has the sole right hereunder to assert a privilege, or if
any party obtains knowledge that any of its or any of its Subsidiaries' current
or former directors, officers, agents or employees have received any subpoena,
discovery or other requests which arguably calls for the production or
disclosure of such privileged information, such party shall promptly notify the
other party or parties of the existence of the request and shall provide the
other party or parties a reasonable opportunity to review the information and to
assert any rights it or they may have under this Section 4.5 or otherwise to
prevent the production or disclosure of such privileged information.

                  (h) The transfer of all Records and other information pursuant
to this Agreement is made in reliance on the agreement of the Corporation and
New D&B, as set forth in Sections 4.4 and 4.5, to maintain the confidentiality
of privileged information and to assert and maintain all applicable privileges.
The access to information being granted pursuant to Sections 4.1 and 4.2 hereof,
the agreement to provide witnesses and individuals pursuant to Sections 2.9 and
3.3 hereof, the furnishing of notices and documents and other cooperative
efforts contemplated by Section 3.3 hereof, and the transfer of privileged
information between and among the parties and their respective Subsidiaries
pursuant to this Agreement shall not be deemed a waiver of any privilege that
has been or may be asserted under this Agreement or otherwise.

                  SECTION 4.6. Ownership of Information. Any non-public
information owned by one party or any of its Subsidiaries that is provided to a
requesting party pursuant to Article III or this Article IV shall be deemed to
remain the property and Intellectual Property of the providing party. Unless
specifically set forth herein, nothing contained in this Agreement shall be
construed as granting or conferring rights of license or otherwise in any such
information.

                  SECTION 4.7. Limitation of Liability. (a) No party shall have
any liability to any other party in the event that any information exchanged or
provided pursuant to this Agreement which is an estimate or forecast, or which
is based on an estimate or forecast, is found to be inaccurate.

<PAGE>   45
                                                                              40

                  (b) No party or any Subsidiary thereof shall have any
liability or claim against any other party or any Subsidiary of any other party
based upon, arising out of or resulting from any agreement, arrangement, course
of dealing or understanding existing on or prior to the Distribution Date (other
than this Agreement or any Ancillary Agreement or any agreement entered into in
connection herewith or in order to consummate the transactions contemplated
hereby or thereby), unless such agreement, arrangement, course of dealing or
understanding is listed on Schedule 4.7(b) hereto, and any such liability or
claim, whether or not in writing, which is not reflected on such Schedule, is
hereby irrevocably canceled, released and waived.

                  SECTION 4.8. Other Agreements Providing for Exchange of
Information. The rights and obligations granted under this Article IV are
subject to any specific limitations, qualifications or additional provisions on
the sharing, exchange or confidential treatment of information set forth in any
Ancillary Agreement.

ARTICLE V.  ADMINISTRATIVE SERVICES

                  SECTION 5.1. Performance of Services. Beginning on the
Distribution Date, each party will provide, or cause one or more of its
Subsidiaries to provide, to the other party and its Subsidiaries such services
on such terms as may be set forth in the Insurance and Risk Management Services
Agreement, the Data Services Agreement and the Transition Services Agreement.
Except as otherwise set forth in the Insurance and Risk Management Services
Agreement, the Data Services Agreement or the Transition Services Agreement or
any Schedule thereto, the party that is to provide the services (the "Provider")
will use (and will cause its Subsidiaries to use) commercially reasonable
efforts to provide such services to the other party (the "Recipient") and its
Subsidiaries in a satisfactory and timely manner and as further specified in the
applicable Agreement.

                  SECTION 5.2. Independence. Unless otherwise agreed in writing,
all employees and representatives of the Provider providing the scheduled
services to the Recipient will be deemed for purposes of all compensation and
employee benefits matters to be employees or representatives of the Provider and
not employees or representatives of the Recipient. In performing such services,
such employees and representatives will be under the direction, control and
supervision of the Provider (and not the Recipient) and the Provider will have
the sole right to exercise all authority with respect to the employment
(including, without limitation, termination of employment), assignment and
compensation of such employees and representatives.

                  SECTION 5.3. Non-exclusivity. Nothing in this Agreement
precludes any party from obtaining, in whole or in part, services of any nature
that may be obtainable from the other party from its own employees or from
providers other than the other party.

<PAGE>   46
                                                                              41

ARTICLE VI.  DISPUTE RESOLUTION

                  SECTION 6.1. Negotiation. In the event of a controversy,
dispute or claim arising out of, in connection with, or in relation to the
existence, interpretation, performance, nonperformance, validity or breach of
this Agreement or otherwise arising out of, or in any way related to this
Agreement or the transactions contemplated hereby, including, without
limitation, any claim based on contract, tort, statute or constitution (but
excluding any controversy, dispute or claim arising out of any agreement
relating to the use or lease of real property if any third party is a party to
such controversy, dispute or claim) (collectively, "Agreement Disputes"), the
general counsels of the parties shall negotiate in good faith for a reasonable
period of time to settle such Agreement Dispute, provided such reasonable period
shall not, unless otherwise agreed by the parties in writing, exceed 30 days
from the date one of the parties first provides written notice to the other that
an Agreement Dispute exists and requests negotiation pursuant to this Section
6.1; provided further that in the event of any arbitration in accordance with
Section 6.2 hereof, the parties shall not assert the defenses of statute of
limitations and laches arising for the period beginning after the date the
parties began negotiations hereunder, and any contractual time period or
deadline under this Agreement or any Ancillary Agreement to which such Agreement
Dispute relates shall not be deemed to have passed until such Agreement Dispute
has been resolved.

                  SECTION 6.2. Arbitration. If after such reasonable period
such general counsels are unable to settle such Agreement Dispute (and in any
event, unless otherwise agreed in writing by the parties, after 60 days have
elapsed from the date one of the parties served notice of an Agreement Dispute
requesting negotiation pursuant to Section 6.1 above), such Agreement Dispute
shall be determined, at the request of any party, by arbitration conducted in
New York City, before and in accordance with the then-existing International
Arbitration Rules of the American Arbitration Association (the "Rules"). In any
dispute between the parties hereto, the number of arbitrators shall be three.
Any judgment or award rendered by the arbitrators shall be final and binding. If
the parties are unable to agree on the arbitrators within 45 days of the
commencement of the arbitration, the arbitrators shall be selected in accordance
with the Rules; provided that each arbitrator shall be a U.S. national. Any
controversy concerning whether an Agreement Dispute is an arbitrable Agreement
Dispute, whether arbitration has been waived, whether an assignee of this
Agreement is bound to arbitrate, or as to the interpretation or enforceability
of this Article VI shall be determined by the arbitrators. In resolving any
dispute, the parties intend that the arbitrators apply the substantive laws of
the State of New York, without regard to conflicts of laws principles. The
parties intend that the provisions to arbitrate set forth herein be valid,
enforceable and irrevocable. The parties agree to comply with any award made in
any such arbitration proceeding that has become final in accordance with the
Rules and agree to enforcement of or entry of judgment upon such award, by any
court of competent jurisdiction, including (a) the Supreme Court of the State of
New York, New York County, or (b) the United States District Court for the
Southern District of New York, in accordance with Section 8.17 hereof. The
arbitrators shall be entitled, if appropriate, to award any remedy in such
proceedings, including, without limitation, monetary damages, specific
performance and all other forms of legal and equitable relief; provided,
however, the parties expressly waive and forego any right to punitive, exemplary
or similar damages unless a statute requires that compensatory damages be
increased in a specified manner. The preceding proviso

<PAGE>   47
                                                                              42

shall not apply to any award of arbitration costs to a party to compensate for
dilatory or bad faith conduct in the arbitration. Without limiting the
provisions of the Rules, unless otherwise agreed in writing by or among the
parties or permitted by this Agreement, the parties shall keep confidential all
matters relating to the arbitration or the award, provided such matters may be
disclosed (i) to the extent reasonably necessary in any proceeding brought to
enforce the award or for entry of a judgment upon the award and (ii) to the
extent otherwise required by law. Notwithstanding Article 31 of the Rules, the
party other than the prevailing party in the arbitration shall be responsible
for all of the costs of the arbitration, including legal fees and other costs
specified by such Article 31. Nothing contained herein is intended to or shall
be construed to prevent any party, in accordance with Article 21(3) of the Rules
or otherwise, from applying to any court of competent jurisdiction for interim
measures or other provisional relief in connection with the subject matter of
any Agreement Disputes.

                  SECTION 6.3. Continuity of Service and Performance. Unless
otherwise agreed in writing, the parties will continue to provide service and
honor all other commitments under this Agreement and each Ancillary Agreement
during the course of dispute resolution pursuant to the provisions of this
Article VI with respect to all matters not subject to such dispute, controversy
or claim.

ARTICLE VII.  INSURANCE

                  SECTION 7.1. Policies and Rights Included Within Assets;
Assignment of Policies. (a) Policy Rights. The New D&B Assets shall include any
and all rights of an insured party under each of the Shared Policies, subject to
the terms of such Shared Policies and any limitations or obligations of New D&B
contemplated by this Article VII, specifically including rights of indemnity and
the right to be defended by or at the expense of the insurer, with respect to
all claims, suits, actions, proceedings, injuries, losses, liabilities, damages
and expenses incurred or claimed to have been incurred on or prior to the
Distribution Date by any party in or in connection with the conduct of the New
D&B Business or, to the extent any claim is made against New D&B or any of its
Subsidiaries, the conduct of the Moody's Business, and which claims, suits,
actions, proceedings, injuries, losses, liabilities, damages and expenses may
arise out of an insured or insurable occurrence under one or more of such Shared
Policies.

                  (b) Assignment of Shared Policies. Subject to the terms and
conditions hereof, the Corporation hereby assigns, transfers and conveys to New
D&B all of the Corporation's right, title and interest in and to any and all of
the Shared Policies, including, without limitation, the right of indemnity, the
right to be defended by or at the expense of the insurer and the right to any
applicable Insurance Proceeds thereunder; and the Corporation and New D&B shall
use their commercially reasonable efforts to obtain any required consents of
insurers to the assignment contemplated by this paragraph.

                  SECTION 7.2. Post-Distribution Date Claims. If, subsequent
to the Distribution Date, any person shall assert a claim against New D&B or any
of its Subsidiaries (including, without limitation, where New D&B or its
Subsidiaries are joint defendants with other persons)

<PAGE>   48
                                                                              43

with respect to any claim, suit, action, proceeding, injury, loss, liability,
damage or expense incurred or claimed to have been incurred on or prior to the
Distribution Date in or in connection with the conduct of the New D&B Business
or, to the extent any claim is made against New D&B or any of its Subsidiaries
(including, without limitation, where New D&B or its Subsidiaries are joint
defendants with other persons), in connection with the conduct of the Moody's
Business, and which claim, suit, action, proceeding, injury, loss, liability,
damage or expense may arise out of an insured or insurable occurrence under one
or more of the Shared Policies, the Corporation shall, at the time such claim is
asserted, to the extent any such Policy may require that Insurance Proceeds
thereunder be collected directly by the named insured or anyone other than the
party against whom the Insured Claim is asserted, be deemed to designate,
without need of further documentation, New D&B as the agent and attorney-in-fact
to assert and to collect any related Insurance Proceeds under such Shared
Policy.

                  SECTION 7.3. Administration; Other Matters. (a)
Administration. After the Distribution Date, New D&B shall be responsible for
(i) Insurance Administration of the Shared Policies and (ii) Claims
Administration under such Shared Policies with respect to Moody's Liabilities
and New D&B Liabilities; provided that the assumption of such responsibilities
by New D&B is in no way intended to limit, inhibit or preclude any right to
insurance coverage for any Insured Claim of a named insured under such Policies
as contemplated by the terms of this Agreement; provided further that New D&B's
assumption of the administrative responsibilities for the Shared Policies shall
not relieve the party submitting any Insured Claim of the primary responsibility
for reporting such Insured Claim accurately, completely and in a timely manner
or of such party's authority to settle any such Insured Claim within any period
permitted or required by the relevant Policy; and provided further that all
direct or indirect communications with insurers relating to the Shared Policies
shall be conducted by New D&B. New D&B may discharge its administrative
responsibilities under this Section 7.3 by contracting for the provision of
services by independent parties. Each of the parties hereto shall administer and
pay any costs relating to defending its respective Insured Claims under Shared
Policies to the extent such defense costs are not covered under such Policies
and shall be responsible for obtaining or reviewing the appropriateness of
releases upon settlement of its respective Insured Claims under Shared Policies.
The disbursements, out-of-pocket expenses and direct and indirect costs of
employees or agents of New D&B relating to Claims Administration and Insurance
Administration contemplated by this Section 7.3(a) shall be treated in
accordance with the terms of the Insurance and Risk Management Services
Agreement or, if the Insurance and Risk Management Services Agreement shall no
longer be in effect, then each of the Corporation and New D&B shall be
responsible for its own Claims Administration and Insurance Administration.

                  (b) Exceeding Policy Limits. The Corporation and New D&B shall
not be liable to one another for claims not reimbursed by insurers for any
reason not within the control of the Corporation or New D&B, as the case may be,
including, without limitation, coinsurance provisions, deductibles, quota share
deductibles, self-insured retentions, bankruptcy or insolvency of an insurance
carrier, Shared Policy limitations or restrictions, any coverage disputes, any
failure to timely claim by the Corporation or New D&B or any defect in such
claim or its processing.

<PAGE>   49
                                                                              44

                  (c) Allocation of Insurance Proceeds. Insurance Proceeds
received with respect to claims, costs and expenses under the Shared Policies
shall be paid to New D&B, which shall thereafter administer the Shared Policies
by paying the Insurance Proceeds, as appropriate, to the Corporation with
respect to Moody's Liabilities and to New D&B with respect to New D&B
Liabilities. Payment of the allocable portions of Insurance Proceeds resulting
from such Policies will be made by New D&B to the appropriate party upon receipt
from the insurance carrier. In the event that the aggregate limits on any Shared
Policies are exceeded by the aggregate of Insured Claims by both of the parties
hereto, the parties agree to allocate the Insurance Proceeds received thereunder
in the same proportion which each party's aggregate Insured Claims bears to the
aggregate of Insured Claims of both of the parties hereto (their "allocable
portion of Insurance Proceeds"), and any party who has received Insurance
Proceeds in excess of such party's allocable portion of Insurance Proceeds shall
pay to the other party the appropriate amount so that each party will have
received its allocable portion of Insurance Proceeds pursuant hereto. Each of
the parties agrees to use commercially reasonable efforts to maximize available
coverage under those Shared Policies applicable to it, and to take all
commercially reasonable steps to recover from all other responsible parties in
respect of an Insured Claim to the extent coverage limits under a Shared Policy
have been exceeded or would be exceeded as a result of such Insured Claim.

                  (d) Allocation of Deductibles. In the event that both parties
have bona fide Insured Claims under any Shared Policy for which an aggregate
deductible is reached, the parties agree that the aggregate amount of the
deductible paid shall be borne by the parties in the same proportion which the
Insurance Proceeds received by each such party bears to the total Insurance
Proceeds received under the applicable Shared Policy (their "allocable share of
the deductible"), and any party who has paid more than such share of the
deductible shall be entitled to receive from the other party an appropriate
amount so that each party has borne its allocable share of the deductible
pursuant hereto.

                  (e) After the Distribution Date, each of New D&B and the
Corporation shall be responsible for its applicable deductible for workers'
compensation, general liability and automobile liability claims.

                  SECTION 7.4. Agreement for Waiver of Conflict and Shared
Defense. In the event that Insured Claims of both of the parties hereto exist
relating to the same occurrence, the parties shall jointly defend and waive any
conflict of interest necessary to the conduct of the joint defense. Nothing in
this Article VII shall be construed to limit or otherwise alter in any way the
obligations of the parties to this Agreement, including those created by this
Agreement, by operation of law or otherwise.

                  SECTION 7.5. Cooperation. The parties agree to use their
commercially reasonable efforts to cooperate with respect to the various
insurance matters contemplated by this Agreement.

                  SECTION 8.1. Complete Agreement; Construction. This
Agreement, including the Schedules and Exhibits, and the Ancillary Agreements
shall constitute the entire agreement between the parties with respect to the

inconsistency between this Agreement and any Schedule hereto, the Schedule shall
prevail. Other than Section 2.1(j), Section 2.7, Section 2.10(e), Section 4.5
and Article VI, which shall prevail over any inconsistent or conflicting
provisions in any Ancillary Agreement, notwithstanding any other provisions in
this Agreement to the contrary, in the event and to the extent that there shall
be a conflict between the provisions of this Agreement and the provisions of any
Ancillary Agreement, such Ancillary Agreement shall control.

                  SECTION 8.2. Ancillary Agreements. Subject to the last
sentence of Section 8.1, this Agreement is not intended to address, and should
not be interpreted to address, the matters specifically and expressly covered by

been signed by each of the parties and delivered to the other parties.

contemplated by this Agreement, all covenants and agreements of the parties
contained in this Agreement shall survive the Distribution Date.

with the preparation, execution, delivery and required implementation of this
Agreement and any Ancillary Agreement, the Information Statement (including any
registration statement on Form 10 (or any amendment thereto) of which such
Information Statement may be a part) and the Distribution and the consummation
of the transactions contemplated thereby, to the extent not paid prior to the
Effective Time. Except as otherwise set forth in this Agreement or any Ancillary
Agreement, each party shall bear its own costs and expenses incurred after the
Effective Time. Any amount or expense to be paid or reimbursed by any party
hereto to any other party hereto shall be so paid or reimbursed promptly after
the existence and amount of such obligation is determined and demand therefor is
made.

                  SECTION 8.6. Notices. All notices and other communications
hereunder shall be in writing and hand delivered or mailed by registered or

negotiations to replace the invalid, illegal or unenforceable provisions with
valid provisions, the economic effect of which comes as close as possible to
