and foreign Income Tax Returns of the Pre-Distribution D&B Group for the 1999
and 2000 Tax years shall be prepared by New D&B and filed by the Corporation,
provided such Tax Returns are prepared in accordance with Section 2.3 hereof.

                  (b) In the case of Tax Returns for non-combined foreign, state
and local Income Taxes and Other Taxes of any member of the Pre-Distribution D&B
Group that may be or are required to be filed for any period beginning before

                  (c) In the case of any partnership in which a member of the

<PAGE>   7
                                                                               7

partner, the Corporation or New D&B, as the case may be, shall cause such entity
to prepare and file such partnership's Tax Returns for all periods beginning
prior to the Distribution Date.

                  SECTION 2.2.  Post-Distribution Tax Returns.

                  (a) The filing of all Tax Returns for periods beginning on or
after the Distribution Date shall be the responsibility of the Corporation if
they relate to any member of the Moody's Group and shall be the responsibility
of New D&B if they relate to any member of the New D&B Group.

                  (b) In the case of any partnership in which a member of the
Pre-Distribution D&B Group is the designated tax matters partner, the
Corporation or New D&B, as the case may be, shall cause such entity to continue
to prepare and file such partnership's Tax Returns.

                       SECTION 2.3. Manner of Preparation.

                  (a) Unless otherwise required by the IRS, any Governmental
Authority or a court, the Parties hereby agree to treat the Distribution Date as
the last day on which any member of the New D&B Group was included in the
Pre-Distribution D&B Group and to file all Tax Returns, and to take all other
actions, in a manner consistent with such position. For any period that includes
but does not end on the Distribution Date, to the extent permitted by law or
administrative practice, the taxable year of each member of the Pre-Distribution
D&B Group and any group of such members shall be treated as ending on the
Distribution Date.

                  (b) In the case of federal Income Tax Returns and combined
state, local and foreign Income Tax Returns, the non-preparing Party to be
included in such Tax Returns shall prepare, in a manner consistent with prior
practice, a tax package for itself and each of its Subsidiaries included in the
relevant Tax Return and shall provide such tax package to the Party preparing
the Tax Return at least 90 days prior to the due date (including extensions) of
the Tax Return. Each such tax package shall be in the form of pro forma Tax
Returns for the non-preparing Party and each of its included Subsidiaries.

                  (c) To the extent not inconsistent with Section 2.3(d) of this
Agreement, with regard to Tax Returns to be prepared by one Party or any of its
Subsidiaries with respect to which the other Party has liability under Article
III hereof, the preparing Party shall submit such Tax Return to the other Party
at least 30 days prior to the date on which such Tax Return is due (including
extensions). The other Party shall submit its comments to the preparing Party
within 10 days of receipt of such Tax Return. The preparing Party shall alter
the Tax Return to reflect the comments of the other Party with respect to Tax
Items in respect of which the other Party is wholly liable for Taxes unless the

<PAGE>   8
                                                                               8

preparing Party receives an opinion of tax counsel, which counsel shall be
reasonably acceptable to the other Party, to the effect that such alteration
would create a significant risk of the imposition of a penalty on the filing
Party or any of its Subsidiaries. New D&B shall propose the positions to be
taken with respect to any Shared Liability Tax Items, and the Parties shall
attempt to reach agreement on positions taken with respect to the Shared
Liability Tax Items. In the event that the Parties cannot agree with respect to
the positions taken on any Shared Liability Tax Items, New D&B shall have the
right to determine the position taken with respect to such Shared Liability Tax
Items; provided, however, that, if the Parties have not agreed with respect to
the position taken, then, notwithstanding Article III hereof, the Corporation
shall not be liable for any additional Tax liability imposed as a result of the
position taken with respect to such Shared Liability Tax Items as compared with
the position proposed by the Corporation.

                  (d) All Tax Returns filed on or after the Distribution Date
shall be prepared on a basis that is consistent with the rulings obtained from
the IRS or any other Governmental Authority in connection with the
Reorganizations or Distribution (in the absence of a controlling change in law
or circumstances) and shall be filed on a timely basis (including pursuant to
extensions) by the Party responsible for such filing under this Agreement. In
the absence of a controlling change in law or circumstances and unless deviation
from past practice would have no adverse effect on either Party, all Tax Returns
filed after the date of this Agreement shall be prepared on a basis consistent
with the elections, accounting methods, conventions, assumptions and principles
of taxation used for the most recent taxable periods for which Tax Returns
involving similar Tax Items have been filed. In the event of a material
deviation from such past practices by either Party, the deviating Party shall
not be in breach of this Agreement, but, notwithstanding Article III, the other
Party shall have no liability for any increased Taxes resulting from such
deviation and the deviating Party shall hold the other Party harmless from any
such increased Tax liability; provided, however, either Party filing any Tax
Return that does not conform to such past practices shall not be liable for any
additional Tax liability imposed (subject to Article III), in whole or in part,
as a result of such deviation from past practice if: (i) for Tax Returns filed
within three years of the Distribution Date, 30 days prior to the filing of such
Tax Return, the Party filing such Tax Return notifies the other Party; and (ii)
the Party filing such Tax Return establishes that conformity with past practice
involves a significant risk of the imposition of a penalty.

ARTICLE III.  PAYMENT OF TAXES

                  SECTION 3.1. Separate Income Taxes. The Moody's Group and the
New D&B Group shall be liable for and shall pay their own

<PAGE>   9
                                                                               9

Separate Company Foreign, State or Local Income Taxes (or be entitled to their
own refunds), including any liabilities arising from any audit adjustment
(including any state, local or foreign audit adjustment resulting from a federal
audit adjustment) for all periods. New D&B and the Corporation shall each be
liable for one-half of any Separate Company Foreign, State or Local Income Taxes
(or be entitled to one-half of such refunds) that do not relate to any member of
the New D&B Group or any member of the Moody's Group.

                  SECTION 3.2.  Combined and Consolidated Income Taxes.
In the case of any Combined and Consolidated Income Taxes:

                  (a) Pre-Distribution Taxes.

                  (i) Unadjusted Taxes. The Corporation and New D&B shall each
be liable for and shall pay one-half of all Unadjusted Taxes (or receive
one-half of such refunds) of the Pre-Distribution D&B Group attributable to the
Pre-Distribution Tax Period to the extent such Unadjusted Taxes become due and
payable (or, in the case of refunds, are received) after the Distribution Date.
The amount of Unadjusted Taxes payable by the Corporation and New D&B pursuant
to this Section 3.2 (a)(i) shall be reduced by the amount of any estimated Taxes
paid by the Pre-Distribution D&B Group (or any member thereof) prior to the
Distribution Date. If the amount of any such estimated Taxes exceeds the amount
of Unadjusted Taxes payable pursuant to this Section 3.2(a)(i), then the Party
benefitting from such excess shall pay the other Party half of the amount of
such excess.

                  (ii) Adjusted Taxes. Adjusted Taxes with respect to any
Pre-Distribution Tax Period (A) shall be the responsibility of New D&B to the
extent that the audit adjustments giving rise to the Adjusted Taxes relate to
any member of the New D&B Group, (B) shall be the responsibility of the
Corporation to the extent that the audit adjustments giving rise to the Adjusted
Taxes relate to any member of the Moody's Group, and (C) shall be shared equally
by the Corporation and New D&B to the extent that the audit adjustments giving
rise to the Adjusted Taxes are attributable to neither a member of the New D&B
Group nor a member of the Moody's Group. Notwithstanding the foregoing, if the
Adjusted Taxes attributable to the New D&B Group or the Moody's Group pursuant
to clauses (A) or (B) as the case may be, on the one hand, are a Tax liability
and the Adjusted Taxes attributable to the other Party pursuant to such clauses,
on the other hand, are a Tax refund, then (x) the Party with respect to which
the Adjusted Taxes are a Tax liability shall pay the full amount of any net
Adjusted Tax liability to the relevant taxing authority; (y) the Party with
respect to which the Adjusted Taxes are a Tax refund shall be entitled to
receive the full amount of any net Adjusted Tax refund from the relevant taxing
authority; and (z) the Party with respect to which the Adjusted Taxes are a Tax
liability shall pay the other Party the amount of such Tax refund (net of any
amount received from a taxing authority pursuant to clause (y)). If the
preceding sentence would apply but for the fact that the Adjusted Taxes in
question are attributed to the Parties pursuant to clause (C) (rather than
clause (A) or (B)), then the preceding sentence shall apply but shall be
modified to account for the shared liability of the Parties pursuant to clause
(C).

                  (b) Post-Distribution Taxes. The Moody's Group and the New D&B
Group shall each be responsible for their own Tax liabilities (or be entitled to
their own refunds) attributable to all Post-Distribution Tax Periods, including
Taxes shown on Tax Returns that have not yet been filed, as well as liabilities
arising from any audit adjustment (including any state, local or foreign audit
adjustment resulting from a federal audit adjustment).

                  (c) Any apportionment of Tax Items between Pre-Distribution
Tax Periods and Post-Distribution Tax Periods will

<PAGE>   10
                                                                              10

be done on a closing of the books basis, except that Tax Items that are
calculated on an annual basis shall be apportioned on a time basis. The
apportionment of subpart F income (as defined in Section 952 of the Code) shall
be governed by the timing provisions of Section 951 of the Code.

                  SECTION 3.3. Other Taxes. The Moody's Group and the New D&B
Group shall each be responsible for their own Other Taxes (or be entitled to
their own refunds) for all periods. New D&B and the Corporation shall each be
liable for one-half of any Other Taxes (or be entitled to one-half of such
refunds) that do not relate to any member of the New D&B Group or any member of
the Moody's Group.

                  SECTION 3.4. Restructuring Taxes. Notwithstanding any
statement to the contrary in this Agreement and except as otherwise provided in
the Distribution Agreement, to the extent that any Taxes are found to arise out
of the Reorganization or the Distribution, then half of any such Tax liability
incurred by the Parties (or any of their Subsidiaries) shall be the
responsibility of New D&B and the other half of any such Tax liability shall be
the responsibility of the Corporation.

                  SECTION 3.5.  Gain Recognition Agreements.

                  (a) Notwithstanding Sections 2.1 and 2.3 of this Agreement,
New D&B shall prepare all documentation required to be filed with any Tax
Returns, including required annual certifications, relating to gain recognition
agreements under Section 367(a) of the Code entered into with respect to
transactions relating to members of the New D&B Group, and the Corporation shall
prepare all documentation required to be filed with any Tax Returns, including
required annual certifications, relating to gain recognition agreements under
Section 367(a) of the Code entered into with respect to transactions relating to
members of the Moody's Group. Such documentation shall be provided to the Party
filing the relevant Tax Return at least 30 days prior to the date on which such
Tax Return is due (including extensions), and the Party filing such Tax Return
shall be obligated to file such documentation with the appropriate Tax Return.

                  (b) In the event that any member of the Moody's Group
transfers, liquidates or otherwise disposes of the stock or assets of any entity
subject to a gain recognition agreement under Section 367(a) of the Code that
results in any member of the New D&B Group recognizing gain pursuant to such
gain recognition agreement, then the Corporation shall be liable for any
resulting Taxes that any member of the New D&B Group is required to pay. In the
event that any member of the New D&B Group transfers, liquidates or otherwise
disposes of the stock or assets of any entity subject to a gain recognition
agreement under Section 367(a) of the Code that results in any member of

<PAGE>   11
                                                                              11

the Moody's Group recognizing gain pursuant to such gain recognition agreement,
then New D&B shall be liable for any resulting Taxes that any member of the
Moody's Group is required to pay.

                  SECTION 3.6.  Indemnification.

                  (a) Indemnification by New D&B. New D&B shall indemnify,
defend and hold harmless the Moody's Group (and their respective affiliates)
from and against any and all Tax liabilities allocated to the New D&B Group by
this Agreement.

                  (b) Indemnification by the Corporation. The Corporation shall
indemnify, defend and hold harmless the New D&B Group (and their respective
affiliates) from and against any and all Tax liabilities allocated to the
Moody's Group by this Agreement.

                  (c) Indemnity Payments.

                  (i) To the extent that one Party (the "Indemnifying Party")
owes money to another Party (the "Indemnitee") pursuant to this Section 3.6, the
Indemnitee shall provide the Indemnifying Party with its calculations of the
amount required to be paid pursuant to this Section 3.6, showing such
calculations in sufficient detail so as to permit the Indemnifying Party to
understand the calculations. The Indemnifying Party shall pay the Indemnitee, no
later than the later of 30 business days prior to the due date (including
extensions) of the relevant Tax Returns and 14 business days after the
Indemnifying Party receives the Indemnitee's calculations, the amount that the
Indemnifying Party is required to pay or indemnify the Indemnitee under this
Section 3.6 unless the Indemnifying Party disagrees with the Indemnitee's
calculations (in which case any dispute regarding such calculations shall be
resolved in accordance with Section 5.4 of this Agreement).

                  (ii) All indemnity payments shall be net of any Tax Benefit
and grossed-up in the case of any Tax Detriment to the Indemnitee as a result of
the payment of such Taxes.

                  (iii) All indemnity payments shall be treated as contributions
to capital and/or dividends immediately prior to the Distribution.

ARTICLE IV.       TAX ATTRIBUTES, TIMING ADJUSTMENTS AND
                  REORGANIZATION TAX PAYMENTS

                  SECTION 4.1. Carrybacks. In the event any net operating loss,
capital loss or credit of either party for any Post-Distribution Tax Period is
eligible to be carried back to a Pre-Distribution Tax Period for which a
consolidated or combined

<PAGE>   12
                                                                              12

Income Tax Return was filed (any such amount, an "Eligible Amount"), such party
may, to the extent permitted under applicable Tax law, elect not to carry back
such Eligible Amount. To the extent any Eligible Amount is carried back by and
used by either New D&B or the Corporation for a Pre-Distribution Tax Period,
then the Corporation shall be obligated to pay one-half of any refund that it
receives as a result of such carried back Eligible Amount to New D&B. Upon
request by the either Party, the other Party shall, within 90 days of such
request, deliver an officer's certificate to the requesting Party stating
whether or not it has any Eligible Amount.

                  SECTION 4.2.  Timing Adjustments, Reorganization Tax
Payments, and Deferred Compensation Deductions.

                  (a) Deferred Compensation Deductions.

                  (i) New D&B shall be entitled to take all Deferred
Compensation Deductions that result from the exercise of stock options in New
D&B, and the Corporation shall be entitled to take all Deferred Compensation
Deductions that result from the exercise of stock options in the Corporation, in
each case notwithstanding the fact that some or all of the services in respect
of which the stock option was granted may have been performed for the other
party. If, after the date of this Agreement, the IRS or any other Governmental
Authority issues rules, regulations or other authority contrary to the above
treatment of such Deferred Compensation Deductions, then New D&B and the
Corporation shall confer and determine whether a change in the above reporting
position should be made. If the parties disagree as to whether the reporting
position should be changed, then counsel reasonably acceptable to both parties
will be retained to make the determination. For purposes of this Agreement, the
issuer's inability to claim such Deferred Compensation Deduction because of a
change in the above reporting position shall be treated as a Deferred
Compensation Adjustment and governed by Section 4.2(a)(ii) below.

                  (ii) If an audit or other examination of any Income Tax Return
for any taxable period shall result (by settlement or otherwise) in a Deferred
Compensation Adjustment, then the Party for whom the Deferred Compensation
Deduction was disallowed (the "Audited Party") shall promptly notify the other
Party (the other Party in this case shall be the Indemnifying Party) of the
disallowance of such Deferred Compensation Deduction. Subject to subsection
(iii) below regarding contests, the Indemnifying Party shall, within 10 days of
such notification, pay the Audited Party the amount of the Tax Detriment to the
Audited Party resulting from the denial of such Deferred Compensation Deduction.
It is the intention of the parties that if at any time the Audited Party is
required to make a payment with respect to such Deferred Compensation
Adjustment, then the Indemnifying Party shall pay the amount of such payment to
the Audited Party prior to the time any such payment is due.

                  (iii) The Indemnifying Party may, within ten business days of
receiving the notification referred to in clause (ii), request the consent of
the Audited Party to contest the denial of the Deferred Compensation Deduction.
The Indemnifying Party and the Audited Party shall consult in good faith
regarding the Audited Party's consent to the contest. The Indemnifying Party may
not contest the denial of any Deferred Compensation Deduction unless (a) the
Indemnifying Party receives written consent from the Audited Party permitting
the contest within ten business days of the Indemnifying Party's request for
such consent; or (b) in the event that the Audited Party does not so consent,
the Indemnifying Party receives an opinion from counsel mutually acceptable to
the Indemnifying Party and the Audited Party stating that the Indemnifying Party
on behalf of the Audited Party will more likely than not prevail in such contest
within 60 days of such request. In either event, to the extent practicable, the
Indemnifying Party shall have the right to control the conduct of the contest,
including settlement or other disposition thereof, and shall bear all costs and
expenses of such contest; provided, however, that the Audited Party shall have
the right to consult with the Indemnifying Party regarding the contest at the
Audited Party's own expense. The Audited Party shall cooperate with the
Indemnifying Party and its representatives in a prompt and timely manner in
connection with such contest. If the Audited Party does not consent to the
contest, and the opinion of counsel referred to in clause (b) is not obtained,
the Indemnifying Party shall pay the amount due to the Audited Party pursuant to
this section at the end of the 60 day period referred to in clause (b). If the
Indemnifying Party contests the denial but does not prevail in such contest, the
Indemnifying Party shall pay the amount due to the Audited Party pursuant to
this section within ten business days of receipt of notice of the final
disposition of the contest.

                  (iv) Withholding and Reporting. If an individual who is
                       --------------------------
employed by either a member of the New D&B Group or a member of the Moody's
Group (the "Employing Member") exercises a stock option in the Corporation (in
the case of an employee of a member of the New D&B Group) or in New D&B (in the
case of an employee of the Moody's Group), the Corporation or New D&B, as the
case may be, shall transfer (or cause to be transferred) to the Employing
Member, within one business day, an amount equal to the amount required to be
withheld from amounts paid to an employee upon the exercise of such option in
order to satisfy the requirements of the Code (and any similar requirements of
state, local or foreign law) with respect to income tax withholding and the
withholding of the employee's share of the Federal Insurance Contributions Act
("FICA") tax and any other amounts required by law to be withheld. The Employing
Member shall fulfill all requirements under the Code (and any similar
requirements of state, local and foreign law) related to the reporting
(including, without limitation, Internal Revenue Service Form W-2 in the case of
employees of the Employing Member and Internal Revenue Service Form 1099 in the
case of non-employee directors of the Employing Member) and payments of any
withheld amounts to the Internal Revenue Service (or other applicable
authority), as well as the payment of the employer's share of the FICA tax and
the Federal Unemployment Tax Act tax.

                  (b) If an audit or other examination of any Income Tax Return
for any taxable period shall result (by settlement or otherwise) in a Timing
Adjustment, or if any Reorganization Tax Payment is made by either Party, then:

<PAGE>   13
                                                                              13

                  (i) The Party benefitting from the Timing Adjustment or
Reorganization Tax Payment shall pay the other Party the Excess Amount of any
Tax Benefit that results from such Timing Adjustment or Reorganization Tax
Payment within 30 business days of the date such Tax Benefits are realized; and

                  (ii) Notwithstanding the foregoing, the Party entitled to
obtain such Tax Benefit shall only be required to take steps to obtain such Tax
Benefit or to pay the other Party if, in the opinion of its tax counsel, which
counsel shall be reasonably acceptable to the other Party, the reporting of such
Tax Benefit shall not expose the first Party to the imposition of a penalty.

                  (c) If an audit or other examination of any Income Tax Return
for any taxable period shall result (by settlement or otherwise) in a Timing
Adjustment to the Tax Detriment of either Party after the Distribution Date,
then the other Party shall pay the Party suffering such Tax Detriment the lesser
of (i) the Excess Amount of any such Tax Detriment and (ii) the Excess Amount of
the actual Tax Benefit to the other Party that results from such Timing
Adjustment.

                  (d) The "Excess Amount" of any Tax Benefit or Tax Detriment is
the absolute value of the difference between (x) the amount of the Tax Benefit
or Tax Detriment and (y) the amount of such Tax Benefit or Tax Detriment
allocable pursuant to this Agreement to the Party obtaining such Tax Benefit or
Tax Detriment.

                  (e) Realization of Tax Benefits.

                  (i) For purposes of this Section 4.2, a Tax Benefit shall be
deemed to have been realized at the time any refund of Taxes is received or
applied against other Taxes due, or at the time of filing of a Tax Return
(including any Tax Return relating to estimated Taxes) on which a loss,
deduction or credit is applied in reduction of Taxes which would otherwise be
payable. Where a Party has other losses, deductions, credits or similar items
available to it, such deductions, credits or similar items of such Party may
only be applied after the use of any Timing Adjustment or Reorganization Tax
Payment.

                  (ii) Either Party may, at its election, pay the amount of any
Tax Benefit to the other Party rather than filing amended returns or otherwise
reflecting adjustments or taking positions on its Tax Returns. If such an
election is made, the Party making such election will be treated as having
realized a Tax Benefit at the time it would have realized a Tax Benefit had it
chosen to file amended returns or otherwise to reflect adjustments or to take
positions on its Tax Returns.

                  (f) Tax Benefits Subsequently Denied. If any Tax Benefit
realized pursuant to Section 4.2(e)(i) is subsequently

<PAGE>   14
                                                                              14

denied, then the Corporation or New D&B, as the case may be, shall be obligated
to refund the amount of any payment for such Tax Benefit in accordance with
Section 3.6(c) of this Agreement.

ARTICLE V.  TAX AUDITS, TRANSACTIONS AND OTHER MATTERS

                  SECTION 5.1.  Tax Audits and Controversies.

                  (a) (i) In the case of any audit, examination or other
proceeding ("Proceeding") brought against either Party (or its Subsidiaries)
with respect to Taxes for which the other Party is or may be liable in whole or
in part pursuant to this Agreement, the Party subject to such Proceeding shall
promptly inform the other Party and shall execute or cause to be executed any
powers of attorney or other documents necessary to enable the other Party to
take all actions desired with respect to such Proceeding consistent with this
Section 5.1. Each Party shall have the right to control, at its own expense, the
portion of any such Proceeding that relates to Taxes for which such Party is or
may be liable pursuant to this Agreement; provided, however, that New D&B shall
have the right to control, with each party bearing half of the related expenses,
that portion of any Proceeding relating to Shared Liability Tax Items.

                      (ii) In the case of a Tax Item in the nature of a refund
for which the Parties share entitlement under this Agreement, the Parties shall
confer in good faith and determine whether and to what extent such refund should
be pursued, with each Party bearing half of the related costs of pursuing such
refund. If the Parties disagree as to the extent to which such refund should be
pursued, the matter shall be referred to an independent accounting firm (or an
independent law firm, in the case of litigation) (each an "Independent Firm")
mutually agreeable to the Parties. If such Independent Firm is able to provide
an opinion that it is "more likely than not" that the Parties shall prevail as
to the claim or claims disputed between the Parties in such refund request, then
the Parties shall proceed with the pursuit of such refund, with costs of such
consultation and all further costs in connection with the pursuit of such refund
shared equally by the Parties. If the Independent Firm is not able to provide
such opinion, neither Party shall further pursue such refund, and the Party that
requested the consultation with the Independent Firm shall bear all of the costs
of such consultation.

                  (b) The Party in control of a Proceeding or any part thereof
pursuant to Section 5.1(a) above shall consult with the other Party with respect
to any issue that may affect such other Party (or its Subsidiaries). The Party
in control of such Proceeding or any part thereof shall not enter into any final
settlement or closing agreement that may adversely affect the other Party (or
its Subsidiaries) without the consent of such other Party, which consent may not
unreasonably be withheld. Where consent to any final settlement or closing
agreement is withheld, the Party withholding consent shall continue or initiate
further proceedings, at its own expense, and the liability of the Party in
control of such Proceeding with respect to Taxes encompassed by the proposed
final settlement or closing agreement shall not exceed the liability that would
have resulted from the proposed closing agreement or final settlement (including
interest, additions to Tax and penalties which have accrued at that time).

                  (c) If New D&B determines that a Proceeding with respect to
any Shared Liability Tax Item should be pursued in the United States District
Court or any other forum in which payment of the Taxes in dispute must be made
in advance, then the Corporation shall make one-half of the advance payment
required, and New D&B shall make the other half of the advance payment required,
with respect to such Shared Liability Tax Item at the time such advance payment
is due. If the total Tax liability with respect to such Shared Liability Tax
Item is later determined to be greater than the amount of the advance payment,
then the Corporation shall pay New D&B one-half of such

<PAGE>   15
                                                                              15

difference, and if the total Tax liability with respect to such Shared Liability
Tax Item is later determined to be less than the amount of the advance payment,
then New D&B shall pay the Corporation one-half of such difference, in either
case at the time of such later determination.

                  (d) If the Indemnifying Party determines that a Proceeding
with respect to any Deferred Compensation Adjustment should be pursued in the
United States District Court or any other forum in which payment of the Taxes in
dispute must be made in advance, then the Indemnifying Party shall make the
advance payment required with respect to such Deferred Compensation Adjustment
at the time such advance payment is due. If the total Tax liability with respect
to such Deferred Compensation Adjustment is later determined to be greater than
the amount of the advance payment, then the Indemnifying Party shall pay the
difference, and if the total Tax liability with respect to such Deferred
Compensation Adjustment is later determined to be less than the amount of the
advance payment, then the Audited Party shall pay the Indemnifying Party the
difference, in either case at the time of such later determination.

                  SECTION 5.2. Cooperation. The Corporation and New D&B shall
cooperate with each other in the filing of any Tax Returns and the conduct of
any audit or other proceeding and each shall execute and deliver such powers of
attorney and other documents and make available such information and documents
as are necessary to carry out the intent of this Agreement. To the extent such
cooperation involves the services of officers, directors, employees, or agents
of either Party, such services shall be made available in accordance with
Section 2.9 of the Distribution Agreement. Each Party agrees to notify the other
Party of any audit adjustment that does not result in Tax liability but can
reasonably be expected to affect Tax Returns of the other Party or any of its
Subsidiaries. Notwithstanding any other provision of this Agreement, if a Party
(the "Nonperforming Party") fails to give its full cooperation and use
reasonably diligent efforts in the conduct of an audit or other proceeding as
provided by this Section 5.2, and such failure results in the imposition of
additional Taxes for the period or periods involved in the audit or other
proceeding, the Nonperforming Party shall be liable in full for such additional
Taxes.

                  SECTION 5.3.  Retention of Records; Access.

                  (a) The Corporation and New D&B shall, and shall cause each of
their Controlled Entities to, retain adequate records, documents, accounting
data and other information (including computer data) necessary for the
preparation and filing of all Tax Returns required to be filed by any member of
the Pre-Distribution D&B Group or any combination of such members and for any
audits and litigation relating to such Tax Returns or to any

<PAGE>   16
                                                                              16

Taxes payable by any member of the Pre-Distribution D&B Group or any combination
of such members.

                  (b) The Corporation and New D&B shall, and shall cause each of
their Controlled Entities to, give to the other Party reasonable access to (i)
all records, documents, accounting data and other information (including
computer data) necessary for the preparation and filing of all Tax Returns
required to be filed by any member of the Pre-Distribution D&B Group or any
combination of such members and for any audits and litigation relating to such
Tax Returns or to any Taxes payable by any member of the Pre-Distribution D&B
Group or any combination of such members and (ii) its personnel and premises,
for the purpose of the review or audit of such reports or returns to the extent
relevant to an obligation or liability of a Party under this Agreement and in
accordance with the procedures provided in Article IV of the Distribution
Agreement.

                  (c) The obligations set forth above in Sections 5.3(a) and
5.3(b) shall continue until the final conclusion of any litigation to which the
records and information relate or until expiration of all applicable statutes of
limitations, whichever is longer. For purposes of the preceding sentence, each
Party shall assume that no applicable statute of limitations has expired unless
such Party has received notification or otherwise has knowledge that such
statute of limitations has expired.

                  (d) Notwithstanding any other provision of this Agreement, if
a Party fails to comply with any of its obligations set forth in this Section
5.3 and such failure results in the imposition of additional Taxes, such
nonperforming Party shall be liable in full for such additional Taxes.

                  SECTION 5.4. Dispute Resolution. Any dispute or claim arising
out of, in connection with, or in relation to the interpretation, performance,
nonperformance, validity or breach of this Agreement or otherwise arising out
of, or in any way related to this Agreement, shall be resolved in the manner set
forth in Article VI of the Distribution Agreement.

                  SECTION 5.5. Confidentiality; Ownership of Information;
Privileged Information. The provisions of Article IV of the Distribution
Agreement relating to confidentiality of information, ownership of information,
privileged information and related matters shall apply with equal force to any
records and information prepared and/or shared by and among the Parties in
carrying out the intent of this Agreement.

ARTICLE VI.  MISCELLANEOUS

be shared equally by the Parties. Except as otherwise set forth in this
Agreement, each Party shall bear its own costs and expenses incurred after the
Distribution Date.

assets to be transferred shall consist of an undivided percentage interest in
each asset that is held by the Corporation Retirement Plan on the Moody's
Retirement Plan Transfer Date, such undivided percentage interest being equal to
the value of assets allocable to such Moody's Transferred Retirement Plan
Employees, divided by the fair market value of plan assets.

                  (d) Prior to the Moody's Retirement Plan Transfer Date, all
benefit payments to Moody's Transferred Retirement Plan Employees shall be made
from the Corporation Retirement Plan.

Trust Agreement. Active participation of Moody's Employees in the Corporation
Savings Plan shall cease immediately after the Effective Time.

                  SECTION 3.2 Moody's Savings Plan. (a) As of the Effective
Time, Moody's shall adopt the Moody's Savings Plan for the benefit of Moody's

(other than Moody's Elective Retirees who shall keep their balances in the
Corporation Savings Plan) shall be given the right to elect one of the following
options with respect to their Corporation Savings Plan account balances (the
"Participant Election Period"): (i) Moody's Employees may keep their balances in
the Corporation Savings Plan (such employees being known as "Moody's Bifurcated
Savings Plan Employees"); or (ii) Moody's Employees may transfer their balances
to the Moody's Savings Plan (such employees being known as "Moody's Transferred
Savings Plan Employees"). If a Moody's Employee fails to elect any of the
foregoing options prior to the end of the Participant Election Period, (i) his
or her balance shall be transferred to the Moody's Savings Plan, and (ii) such
employee shall be treated as a Moody's Transferred Savings Plan Employee.

liabilities to the Moody's Savings Plan shall occur (the "Moody's Savings Plan
Transfer Date"), which date shall occur as promptly as practicable following the
Participant Election Period, (i) New D&B shall (A) cause the trustee of the
Corporation Savings Plan to segregate, in accordance with the spinoff provisions
set forth under Section 414(l) of the Code, the assets of the Corporation
Savings Plan representing the full account balances of Moody's Transferred
Savings Plan Employees for all periods of participation through the Effective
Time (including, as applicable, all contributions and all earnings attributable
thereto); (B) make all required filings and submissions to the appropriate
governmental agencies; and (C) make all required amendments to the Corporation
Savings Plan and related trust agreement necessary to provide for the
segregation and transfer of assets described in this Section 3.2, and (ii) if
requested by New D&B, Moody's shall furnish to New D&B a favorable determination
letter that the Moody's Savings Plan is qualified under Section 401(a) of the
Code.

                  (c) On the Moody's Savings Plan Transfer Date, New D&B shall
cause the trustee of the Corporation Savings Plan to transfer to the trustee of
the Moody's Savings Plan the full account balances (inclusive of loans) of
Moody's Transferred Savings Plan Employees in cash or in kind based on those
investment funds in which such account balances are then invested (including,
but not limited to, the stock funds); provided, however, that loans to Moody's
Transferred Savings Plan Employees shall be transferred in the form of notes. In
consideration of the segregation and transfer of assets described herein, the
Moody's Savings Plan shall, as of the Moody's Savings Plan Transfer Date, assume
all Liabilities attributable to such assets.

                  SECTION 3.3 Vesting. As of the Effective Time, the account
balances of Moody's Employees (other than Moody's Elective Retirees) in the
Corporation Savings Plan shall fully vest. Future employer contributions by
Moody's under the Moody's Savings Plan shall vest based on the vesting schedule
thereunder.

                  SECTION 3.4 Outstanding Loans. During their employment with
Moody's, Moody's Transferred Savings Plan Employees who have outstanding loans
originally made from the Corporation Savings Plan shall be permitted to repay
such loans by way of regular deductions from their paychecks, and, prior to the
Moody's Savings Plan Transfer Date, Moody's or New D&B (as the case may be)
shall cause all such deductions to be forwarded to the Corporation Savings Plan
as promptly as practicable. After the Effective Time, no such deductions by
Moody's shall be made in respect of Moody's Bifurcated Savings Plan Employees
who have outstanding loans from the Corporation Savings Plan, and all such
employees shall be required to repay their loans directly to the Corporation
Savings Plan in accordance with the existing terms thereof.

                  SECTION 3.5 Employer Stock Fund. (a) Participants in the
Corporation Savings Plan who, immediately prior to the Effective Time, have
balances in the Corporation Common Stock fund shall have such balances
converted, as of the Effective Time, to the extent applicable, to units in two
stock funds. The Corporation Savings Plan shall maintain a nonemployer stock
fund consisting of only Moody's Common Stock ("Moody's Stock Fund") and an
employer stock fund consisting of only New D&B Common Stock ("New D&B Stock
Fund"). The Moody's Stock Fund will initially consist of the same number of
shares of Moody's Common Stock as the number of shares of Corporation Common
Stock in the Corporation Common Stock fund immediately prior to the Effective
Time. The New D&B Stock Fund will initially consist of a number of shares of New
D&B Common Stock equal to fifty percent of the number of shares of Corporation
Common Stock in the Corporation Common Stock fund immediately prior to the
Effective Time. The initial percentage interest of each participant in each
stock fund as of the Effective Time shall equal such participant's percentage
interest in the Corporation Common Stock fund immediately prior to the Effective
Time. The Moody's Savings Plan shall maintain a Nonemployer Stock fund to which
the New D&B Stock Fund assets of Moody's Transferred Savings Plan Employees in
the Corporation Savings Plan shall be transferred on the Moody's Savings Plan
Transfer Date. The Moody's Savings Plan shall also maintain an employer stock
fund to which the Moody's Stock Fund assets of Moody's Transferred Savings Plan
Employees in the Corporation Savings Plan shall be transferred on the Moody's
Savings Plan Transfer Date.

                  (b) Neither a Moody's Savings Plan participant nor a
Corporation Savings Plan participant may transfer or contribute any amounts to a
Nonemployer Stock fund from or after the Effective Time.

                  SECTION 3.6 Allocation of Liabilities. The Moody's Group shall
retain all Liabilities relating to account balances of Moody's Transferred
Savings Plan Employees under the Corporation Savings Plan. The New D&B Group
shall assume Liabilities relating to account balances of all other participants
under the Corporation Savings Plan. All other Liabilities relating to the
Corporation Savings Plan prior to the Distribution Date that are not allocated
in accordance with the foregoing provisions of this Article III (including,
without limitation, Liabilities resulting from the administration of the plan or
the qualified status of the plan) shall be assumed and/or retained equally by
Moody's and New D&B.

                               NONQUALIFIED PLANS

                  SECTION 4.1 Corporation Nonqualified Plans. Prior to the
Effective Time, New D&B shall assume and become the sponsor of the Corporation
Supplemental EBP, the Corporation Supplemental EBP Trust, the Corporation
Pension BEP, the Corporation Pension BEP Trust and the Corporation Savings BEP
(collectively, the "Corporation Nonqualified Plans") for the benefit of persons
who, prior to the Effective Time, were participants thereunder; provided,
however, that, with respect to Moody's Employees, (i) Moody's shall retain the
liability for benefits under the Corporation Savings BEP and (ii) New D&B shall
retain only those Liabilities for benefits under the Corporation Nonqualified
Plans (other than the Corporation Savings BEP) that, prior to the Effective
Time, were accrued and to which such participants had earned vested rights
thereunder. Notwithstanding the foregoing, the Liabilities retained by New D&B
under such plans (i) shall not include the Liabilities resulting from benefits
payable to participants who are not Corporation Employees not reflected in the
determination, as of the Effective Time, of such Liabilities, such Liabilities
resulting from such benefits shall be assumed and/or retained equally by Moody's
and New D&B and (ii) shall be appropriately adjusted to reflect (A) increases in
the contribution limits imposed by Section 415 of the Code and (B) future
accruals under the Moody's pension plans.

                  SECTION 4.2 Service Credit. Moody's Employees who were
participants with vested benefits in the Corporation Nonqualified Plans
immediately prior to the Effective Time (the "Moody's Nonqualified Plan
Participants") shall continue to receive service credit under such plans for
their service with the Moody's Group from and after the Effective Time, but
solely for purposes of satisfying the one-year waiting requirement for a valid
election under the Corporation Nonqualified Plans.

                  SECTION 4.3 Consent to Termination. Solely with respect to

                  SECTION 4.4 Termination of Employment. Benefits under the

Nonqualified Plan Participant until such participant terminates employment from
the Moody's Group and is otherwise eligible to receive such payment under the
terms of the Corporation Nonqualified Plans.

                  SECTION 4.5 Noncompetition. Solely with respect to the
noncompetition clauses of the Corporation Nonqualified Plans, New D&B hereby
consents to the employment of the Corporation Nonqualified Plan Participants by
the Moody's Group after the Effective Time, whether or not such employment would
otherwise trigger such noncompetition clauses.

                  SECTION 4.6 Distributions. Moody's Nonqualified Plan
Participants who participated in the Corporation Savings BEP immediately prior
to the Effective Time shall receive a distribution thereunder from the Moody's
Group, based on their notional elective deferrals through the Effective Time, at
the time distributions are otherwise made under such plan.

                  SECTION 4.7 Guarantees; Subrogation. The Moody's Group agrees
that, in the event the New D&B Group is unable to satisfy its obligations in
respect of the benefits of any Moody's Employee that have accrued under the
Corporation Nonqualified Plans prior to the Effective Time, the Moody's Group
shall make payment when due with respect to such obligations of the New D&B
Group. In the event that the Moody's Group is required to make any payment
pursuant to this Section 4.7, the Moody's Group shall have full rights of
subrogation against the New D&B Group.

                  SECTION 4.8 Third-Party Beneficiaries. It is the intention of
the parties to this Agreement that the provisions of Section 4.7 shall be
enforceable by (a) the Moody's Nonqualified Plan Participants and (b) their
respective surviving beneficiaries.

                  SECTION 4.9 Nonemployee Director Deferred Compensation
Plan/Corporation Director Retirement Plan. (a) As of the Effective Time, New D&B

Corporation and R.H. Donnelley Inc., with respect to certain nonqualified plans
maintained by Corporation prior to such dates. To the extent joint and several
liability is imposed on Moody's in respect of a liability assumed by New D&B
under this Agreement, Moody's shall be entitled to contribution from New D&B for
the amount of such liability imposed. To the extent joint and several liability
is imposed on New D&B in respect of a liability assumed by Moody's under this
Agreement, New D&B shall be entitled to contribution from Moody's for the amount

                  SECTION 5.1 Employee Benefit Welfare Plans. Prior to the
Effective Time, Corporation shall continue to sponsor its Employee Benefit
Welfare Plans for the benefit of the Corporation Employees. Except as provided
in Section 5.4 and Section 5.6 below, from and after the Effective Time, Moody's
shall continue to sponsor its Employee Benefit Welfare Plans solely for the
benefit of Moody's Employees. From and after the Effective Time, New D&B shall
sponsor its Employee Benefit Welfare Plans for the benefit of New D&B Employees
and Corporation Retirees who participated in the Corporation Employee Benefit
Welfare Plans immediately prior to the Effective Time. Notwithstanding the
foregoing, neither Moody's nor New D&B shall have any obligation to sponsor any
Employee Benefit Welfare Plan from or after the Effective Time.

                  SECTION 5.2 Pre-Existing Conditions; Dollar Limits. With
respect to any medical plan that may be sponsored by New D&B and Moody's after

deductible and maximum out-of-pocket limitations, to claims incurred, and
amounts paid by, and amounts reimbursed to, (in each case during 2000 prior to
the Effective Time) New D&B Employees, Moody's Employees and Corporation
Retirees under similar plans maintained by Corporation (or any Affiliate
thereof) for their benefit immediately prior to the Effective Time.

                  SECTION 5.3 Severance Plans. The Moody's Group shall retain

For purposes of this Section 5.3, the term "severance payments" shall include

                  SECTION 5.4 Flexible Spending Accounts. From the Effective

after the Effective Time. New D&B shall cause the trustee of the Master Welfare

allocable to the Moody's Disabled Employees who became disabled prior to January

establish the Moody's Long-Term Disability Plan for the benefit of Moody's
Disabled Employees and the assets allocable to the Moody's Employees who became
disabled prior to January 1, 1994 shall be transferred to a separate trust
established under the Moody's Long-Term Disability Plan (the "Moody's Long-Term
Disability Plan Transfer Date"). The value of such assets to be transferred
shall be adjusted as follows:

         (a)      reduced by the amount of benefit payments made under the
                  Corporation Long-Term Disability Plan with respect to such
                  Moody's Disabled Employees from the Effective Time to the
                  Moody's Long-Term Disability Plan Transfer Date; and

         (b)      increased (or decreased) by the share of the net investment
                  income (or loss) and decreased by the share of investment
                  expenses from the Effective Time to the Moody's Long-Term
                  Disability Plan Transfer Date attributable to the value of
                  such segregated assets.

                  SECTION 5.6 Allocation of Liabilities. (a) The Moody's Group
shall retain responsibility for and continue to pay all expenses and benefits
relating to (i) the Corporation Long-Term Disability Plans with respect to
claims incurred by Moody's Disabled Employees, regardless of when such claims
are incurred and (ii) the Corporation Employee Benefit Welfare Plans with
respect to claims incurred from and after the Effective Time by Moody's
Employees as well as their dependents. The New D&B Group shall be responsible
for and pay expenses and benefits relating to all Employee Benefit Welfare Plan
claims (i) incurred prior to the Effective Time by Corporation Employees,
Moody's Disabled Employees and their covered dependents (other than claims
incurred by Moody's Disabled Employees under the Corporation Long-Term
Disability Plans) and (ii) incurred by New D&B Employees and Corporation
Retirees as well as their covered dependents from and after the Effective Time.
For purposes of this paragraph, a claim is deemed incurred when the services
that are the subject of the claim are performed; in the case of life insurance,
when the death occurs; in the case of long-term disability, when the disability
occurs; and, in the case of a hospital stay, when the employee first enters the
hospital. Notwithstanding the foregoing, claims incurred by any employee of a
pre-Distribution Subsidiary of the Corporation or their covered dependents under

Subsidiary solely for the benefit of its employees and their dependents shall,
whether incurred prior to, on or after the Effective Time, be the sole
responsibility and liability of that Subsidiary.

                  (b) The Moody's Group shall be responsible for all COBRA
coverage for (i) any Corporation Employee who would have been a Moody's Employee
but for the qualifying event and his or her covered dependents who participated
in a Corporation Employee Benefit Welfare Plan and who had or have a loss of
health care coverage due to a qualifying event occurring prior to the Effective
Time and (ii) any Moody's Employee who is entitled to COBRA coverage as a result
of a qualifying event occurring at or after the Effective Time. The New D&B
Group shall be responsible for all COBRA coverage for any other Corporation
Employee and his or her covered dependents who participated in a Corporation
Employee Benefit Welfare Plan and who had or have a loss of health care coverage
due to a qualifying event occurring prior to the Effective Time. Notwithstanding
the foregoing, a pre-Distribution Subsidiary of Corporation shall be responsible
for all COBRA coverage for its former employees and covered dependents who
participated in a plan maintained solely for their benefit whether the
applicable event occurs prior to, on or after the Effective Time.

                  SECTION 5.7 Retiree Welfare Plans. The Moody's Group shall be

                               EQUITY-BASED PLANS

                  SECTION 6.1 Corporation Stock Options. Stock options awarded
under the Corporation Stock Incentive Plans ("Corporation Stock Options") shall
be treated as follows:

                  (a) Except as provided in Section 6.1(d) of this Agreement, as
of the Effective Time, each unexercised Corporation Stock Option held by any
Person shall be adjusted, pursuant to the terms of the award agreements and the
Corporation Stock Incentive Plans, into an option to purchase Moody's Common
Stock (a "Moody's Option") held pursuant to the Corporation Stock Incentive
Plans and a separately exercisable option, granted pursuant to the New D&B
Replacement Plans, to purchase New D&B Common Stock (a "New D&B Option"). The
number of shares of Moody's Common Stock covered by the Moody's Option shall
equal the number of shares of Corporation Common Stock covered by the
corresponding Corporation Stock Option immediately prior to the Effective Time
and the number of shares of New D&B Common Stock covered by the New D&B Option
shall equal fifty percent of the number of shares of Corporation Common Stock
covered by the corresponding Corporation Stock Option immediately prior to the
Effective Time, rounded down to the nearest whole share.

                  (b) The exercise price per share of each Moody's Option shall
equal the product of (A) the excess of (i) the trading price per share of
Corporation Common Stock as of last trade "regular way" immediately prior to the
Distribution (the "Corporation Stock Price") over (ii) the quotient of (a) the
trading price per share of New D&B Common Stock as of the last trade "when
<PAGE>   19
                                                                              19

issued" immediately prior to the Distribution (the "New D&B Stock Price")
divided by (b) two, multiplied by (B) a fraction, the numerator of which is the
original exercise price per share of the corresponding Corporation Stock Option,
and the denominator of which equals the Corporation Stock Price (the "Conversion
Ratio").

                  (c) The exercise price per share of each New D&B Option shall
equal the New D&B Stock Price multiplied by the Conversion Ratio. Except as
otherwise provided in the New D&B Replacement Plans and this Section 6.1(a), the
terms of each New D&B Option shall be substantially identical to the terms of
the Corporation Stock Option from which it arose.

                  (d) In accordance with the terms of the employment agreement
dated May 15, 2000 between the Corporation and Allan Z. Loren (the "Loren
Agreement"), as of the Effective Time, the Corporation Stock Options held by Mr.
Loren shall be canceled and, in lieu thereof, New D&B shall issue replacement
New D&B Options.

                  SECTION 6.2 Corporation SARs. All stock appreciation rights

                  (b) Moody's shall, as soon as practicable, inform New D&B of
the lapse of restrictions with respect to the Corporation Restricted Stock held
by New D&B Directors. In the event that Dividended Restricted Stock is forfeited
by a Moody's Director or New D&B Director, such forfeited Dividended Restricted
Stock shall be forfeited directly to New D&B.

                  (c) In accordance with the terms of the Loren Agreement, as of
the Effective Time, the shares of restricted stock of the Corporation granted to
Mr. Loren and the Dividended Restricted Stock shall be forfeited and, in lieu
thereof, New D&B shall grant Mr. Loren shares of restricted stock of New D&B.

                  SECTION 6.4 Performance Shares. Performance shares awarded
under the Corporation Stock Incentive Plans ("Corporation Performance Shares")
shall be treated as follows:

                  (a) Moody's Employees. Moody's Employees shall receive,

equal to fifty percent of the number of such Corporation Performance Shares.

                  (b) New D&B Employees. As of the Effective Time, Corporation
Performance Share opportunities granted to New D&B Employees shall be canceled
and such individuals shall receive a replacement performance share opportunity,
pursuant to the New D&B Replacement Plan, consisting of (i) a number of shares
of New D&B Common Stock equal to fifty percent of the target number of
Corporation Performance Shares plus (ii) a cash payment opportunity equal to the
fair market value (as of the date the award is approved) of a number of shares
of Moody's Common Stock equal to the target number of Corporation Performance
Shares.

                  (c) Performance Data. As soon as practicable, but no later

awarded to each Moody's Director and New D&B Director ("Corporation Phantom

Stock Units held by such Moody's Director or New D&B Director immediately prior
to the Distribution and a number of New D&B Phantom Stock Units equal to fifty
percent of the number of Corporation Phantom Stock Units held by such
Corporation Director immediately prior to the Distribution. As of the Effective
Time, the Moody's Group shall retain Liabilities relating to the Moody's Phantom
Stock Units and the New D&B Phantom Stock Units held by Moody's Directors. As of
the Effective Time, the New D&B Group shall assume Liabilities with respect to
the Moody's Phantom Stock Units and the New D&B Phantom Stock Units held by all
other Corporation Directors. Except as otherwise provided in the New D&B
Replacement Plans, the Corporation Stock Incentive Plans, this Section 6.6 or
Section 6.8, the Moody's Phantom Stock Units and the New D&B Phantom Stock Units
will have the same terms and conditions as the Corporation Phantom Stock Units
from which they arose.

                  SECTION 6.7 Performance Share Units. The performance share
units awarded to each Moody's Director and New D&B Director ("Corporation
Performance Share Units") shall be adjusted into a number of Moody's Performance

to the New D&B Replacement Plan, equal to fifty percent of the number of
Corporation Performance Share Units held by such Moody's Director or New D&B
Director immediately prior to the Distribution, rounded down to the nearest
whole share. Except as otherwise provided in the New D&B Replacement Plans, the
Corporation Stock Incentive Plans, this Section 6.7 and Section 6.8, each
Moody's Performance Share Unit and each New D&B Performance Share Unit will have
the same terms and conditions as the Corporation Performance Share Unit from
which it arose.

                  SECTION 6.8 Termination of Employment/Service. (a) With
respect to each New D&B Option, stock appreciation right for New D&B Common
Stock, New D&B Performance Share Unit and Dividended Restricted Stock granted to
a Moody's Employee or Moody's Directors (other than a Moody's Director who is a
member of the Board of Directors of New D&B) pursuant to the New D&B Replacement
Plans, the New D&B Replacement Plans shall provide that references under such
plans to continued employment or service or termination of employment or service

employment or service of a Moody's Employee or a Moody's Director, respectively,
Moody's shall, as soon as practicable, inform New D&B of such termination of
employment or service whether such termination was due to death, disability or
retirement and whether the New D&B Options granted to such Moody's Employee or
Moody's Director were cashed-out in cancellation of such New D&B Options.

                  SECTION 6.9 Change in Control. To the extent an award granted
