Benefit is $10,000 or less at the time such Retirement  Benefit is payable under
this Plan, such benefit shall be payable as a lump sum.
     (d) If the  Retirement  Benefit under this Plan is payable to a Participant
or Vested Former Participant in a different form and/or at a different time than
his Other Retirement  Income or his Basic Plan Benefits,  the offset provided in
this Plan for such Participant's or Vested Former Participant's Other Retirement
Income and Basic Plan Benefit shall be converted,  using  actuarial  assumptions
that are reasonable and appropriate and in accordance with applicable law at the
time the  benefit  under  this Plan is  determined,  to the extent  required  as
follows, but solely for purposes of calculating the amount of such offset:






     (i) a percentage  of the benefits to be offset equal to the  percentage  of
such Participant's or Vested Former  Participant's  benefits payable in the form
of an  annuity  under  this Plan shall be  actuarially  converted  to the extent
required into the form of a straight  life annuity,  commencing at the time such
benefits  payable  under this Plan commence or on the date such  Participant  or
Vested Former  Participant  would first become  eligible for the payment of such
benefits under this Plan, if earlier; and
     (ii) the balance, if any, of the benefits to be offset shall be actuarially
converted  to a lump sum payment  payable on the date which is 60 days after the
date described in Section 4.4(d)(i).
              4.5  (a) A  Participant  may  elect,  on a  form  supplied  by the
Committee,  to receive all, none, or a specified portion, as provided in Section
4.5(c),  of his  Retirement  Benefit under the Plan in a lump sum and to receive
any balance of such Retirement Benefit in the form of an annuity;  provided that
any such  Election  shall be  effective  for  purposes  of this Plan only if the
conditions of Section  4.5(b) are satisfied.  A Participant  may elect a payment
form  different  than the  payment  form  previously  elected  by him under this
Section  4.5(a) by filing a revised  election  form;  provided that any such new
Election  shall be  effective  only if the  conditions  of  Section  4.5(b)  are
satisfied  with  respect  to such new  Election.  Any prior  Election  made by a
Participant  that  has  satisfied  the  conditions  of  Section  4.5(b)  remains
effective  for  purposes  of the  Plan  until  such  Participant  has made a new
Election  satisfying the conditions of Section 4.5(b). The amount of any portion
of a Participant's or a Vested Former  Participant's  Retirement Benefit payable
as a lump sum  under  this  Section  4.5 will  equal the  present  value of such
portion of the  Retirement  Benefit,  and such present value shall be determined
(i)  based  on a  discount  rate  equal  to 85% of the  average  of the  15-year
non-callable  U.S.  Treasury bond yields as of the close of business on the last
business  day of each of the three  months  immediately  preceding  the date the
annuity  value is  determined  and (ii) using the 1983 Group  Annuity  Mortality
Table.



     (b) A Participant's Election under Section 4.5(a) becomes effective only if
the following  conditions are  satisfied:  (i) such  Participant  remains in the
employment of the Corporation or an Affiliate,  as the case may be, for the full
twelve calendar months immediately following the Election Date of such Election,
except in case of death or disability of such Participant as provided in Section
4.5(d) and (ii) such Participant complies with the administrative procedures set
forth by the Committee with respect to the making of the Election.
     (c) A Participant  making an election  under Section 4.5(a) may specify the
portion of his Retirement Benefit under the Plan to be received in a lump sum as
follows: 0 percent, 25 percent, 50 percent, 75 percent or 100 percent.
     (d) In the event a Participant who has made an Election pursuant to Section
4.5(a) dies or becomes  totally and  permanently  disabled  for  purposes of the
relevant Basic Disability Plan while employed by the Corporation or an Affiliate
and  such  death  or  total  and   permanent   disability   occurs   during  the
twelve-calendar-month period, as described under Section 4.5(b)(i),  immediately
following  the Election  Date of such  Election,  the  condition  under  Section
4.5(b)(i) shall be deemed satisfied with respect to such Participant.
              4.6 (a) Any  Participant  (except  the  Chairman  of the  Board of
Directors of the  Corporation  on December 21, 1994) who as of December 31, 1994
(i) is age 54 or older  and (ii) has at least 4 years of  Credited  Service  may
elect, on a form supplied by the Committee, to receive all, none, or a specified
portion,  in the  same  percentages  as  described  in  Section  4.5(c),  of his
Retirement  Benefit  under the Plan in a lump sum and to receive  any balance of
such  Retirement  Benefit  in the  form of an  annuity;  provided  that any such
Special  Election  shall be  effective  for  purposes  of this Plan only if such
Participant  remains in employment with the Corporation or an Affiliate,  as the
case may be, for the one calendar month immediately following the Election Date,
except in the case of death or total and  permanent  disability  as  provided in
Section 4.6(b), and complies with the administrative procedures set forth by the
Committee  for making such  Special  Election;  and  provided  further  that the
Election  Date with  respect  to any such  Special  Election  is not later  than
January  31,  1995.  The amount of any  portion of a  Participant's  or a Vested
Former Participant's Retirement Benefit payable as a lump sum under this Section
4.6 will equal the present value of such portion of the Retirement Benefit,  and
such present value shall be determined (i) based on a discount rate equal to the
average of 85% of the 15-year  non-callable  U.S. Treasury bond yields as of the
close  of  business  on the  last  business  day of  each  of the  three  months
immediately  preceding the date the annuity  value is determined  and (ii) using
the 1993 Group Annuity Mortality Table.
     (b) In the event a Participant who has made a Special Election  pursuant to
Section 4.6(a) dies or becomes totally and permanently  disabled for purposes of
the relevant  Basic  Disability  Plan while  employed by the  Corporation  or an
Affiliate  and such death or total and  permanent  disability  occurs during the
one-calendar-month   period,  as  described  under  Section  4.6(a)  immediately
following  the  Election  Date of such Special  Election,  the  condition  under
Section  4.6(a)  requiring  that  such  Participant  remain  employed  with  the
Corporation  or an  Affiliate,  as the case may be,  for the  one-calendar-month
period immediately  following the Election Date of such Election shall be deemed
satisfied.
              4.7  Subject to Section  3.1,  Section  3.3,  Section  3.4 and the
foregoing  limitations  of  this  Section  4,  the  Retirement  Benefit  of each
Participant and Vested Former  Participant  under the Plan shall at all times be
100% vested and nonforfeitable.
              4.8 (a) Subject to Section 4.8(c), the Corporation shall indemnify
each  Participant,  Vested Former  Participant and Surviving Spouse who receives
any portion of a Retirement  Benefit or Surviving  Spouse's  Benefit  under this
Plan in the  form of an  annuity  for any  interest  and  penalties  that may be
assessed by the U.S.  Internal  Revenue  Service (the "Service") with respect to
U.S. Federal income tax on such benefits  (payable under the Plan in the form of
an  annuity)  upon  final  settlement  or  judgment  with  respect  to any  such
assessment  in favor of the Service,  provided the basis for the  assessment  is
that the  amendment  of the Plan to  provide  for the  Election  or the  Special
Election causes the Participant,  Vested Former Participant or Surviving Spouse,
as the case may be,  to be  treated  as being in  constructive  receipt  of such
benefits  prior to the time when such  benefits are actually  payable  under the
Plan.





     (b) In case any  assessment  shall be made  against a  Participant,  Vested
Former  Participant  or Surviving  Spouse as described in Section  4.8(a),  such
Participant,  Vested Former  Participant or Surviving Spouse, as the case may be
(the "indemnified party"), shall promptly notify the Corporation's  Treasurer in
writing and the  Corporation,  upon  request of such  indemnified  party,  shall
select and retain an accountant or legal counsel reasonably  satisfactory to the
indemnified  party to represent the  indemnified  party in connection  with such
assessment  and shall pay the fees and expenses of such an  accountant  or legal
counsel related to such representation, and the Corporation shall have the right
to  determine  how and when such  assessment  by the Service  should be settled,
litigated or appealed.  In connection with any such assessment,  any indemnified
party shall have the right to retain his own  accountant or legal  counsel,  but
the fees and  expenses  of such  accountant  or  legal  counsel  shall be at the
expense of such  indemnified  party unless the  Corporation  and the indemnified
party shall have mutually  agreed to the  retention of such  accountant or legal
counsel.
     (c) The Corporation shall not be liable for any payments under this Section
4.8 with respect to any assessment described in Section 4.8(a) if a Participant,
Vested Former  Participant or Surviving  Spouse against whom such  assessment is
made has not promptly  notified or allowed the  Corporation to participate  with
respect  to such  assessment  in the  manner  described  in  Section  4.8(b) or,
following  demand  by the  Corporation,  has  not  made  the  deposit  to  avoid
additional  interest or penalties  as described in Section  4.8(d) or has agreed
to, or  otherwise  settled  with the Service  with  respect to, such  assessment
without  the  Corporation's  written  consent,  provided,  however,  (i) if such
assessment is settled with such consent or if there is a final  judgment for the
Service,  (ii) the  Corporation  has been notified and allowed to participate in
the manner as  provided  in Section  4.8(b) and (iii) such  Participant,  Vested
Former  Participant or Surviving  Spouse has made any required  deposit to avoid
additional  interest or penalty as described in Section 4.8(d),  the Corporation
agrees  to  indemnify  the  indemnified  party to the  extent  set forth in this
Section 4.8.




     (d) In the  event  a  final  settlement  or  judgment  with  respect  to an
assessment as described  under Section 4.8 has been made against a  Participant,
Vested Former Participant or Surviving Spouse,  such Participant,  Vested Former
Participant  or  Surviving  Spouse  may elect to receive a portion or all of his
Retirement Benefit or Surviving Spouse's Benefit that is otherwise payable as an
annuity under the Plan in the form of a lump sum in accordance  with  procedures
as the Committee may set forth, and such lump sum  distribution  will be made as
soon as practicable after any such election. At the time such assessment is made
against such  Participant,  Vested Former  Participant or Surviving  Spouse (the
"assessed  party") and prior to any final settlement or judgment with respect to
such assessment,  if so directed by the Corporation,  such assessed party shall,
as a condition to  receiving  any  indemnity  under this Section 4.8, as soon as
practicable  after  notification  of such  assessment  make a  deposit  with the
Service to avoid any  additional  interest  or  penalties  with  respect to such
assessment and, upon the request of such assessed party,  the Corporation  shall
lend,  or arrange  for the  lending  to,  such  assessed  party a portion of his
remaining  Retirement  Benefit or Surviving Spouse's Benefit under the Plan, not
to exceed the lump sum value of such benefit  under the Plan,  determined  using
the actuarial  assumptions set forth in Section  4.5(a),  solely for purposes of
providing  the  assessed  party with funds to make a deposit with the Service to
avoid any additional interest or penalties with respect to such assessment.





                                    SECTION 5
                               Disability Benefits
              5.1 The  Disability  Benefit  provided  by the Plan is designed to
provide each  Participant  with a  disability  benefit from the Plan and certain
other sources equal to his Disability  Benefit as hereinafter  specified.  Thus,
Disability  Benefits  described  hereunder  as payable to  Participants  will be
offset by disability  benefits payable from sources outside the Plan (other than
benefits payable under the relevant Basic Disability Plan) as specified herein.
              5.2 In the  event  that  a  Participant  has  become  totally  and
permanently  disabled for the purposes of the relevant Basic Disability Plan, an
annual Disability  Benefit shall be payable in monthly  installments  under this
Plan during the same period as  disability  benefits are actually or deemed paid
by  the  relevant  Basic  Disability  Plan,  in an  amount  equal  to 60% of the
Participant's  Basic Earnings.  Such  Disability  Benefit shall be offset by the
Participant's  Other  Disability  Income,  if any.  A  Participant's  Disability
Benefits shall also be offset by the  Participant's  Basic Plan Benefit,  if the
Participant's  Basic  Disability  Plan Benefit does not already  include such an
offset.

                                    SECTION 6
                           Surviving Spouse's Benefits
              6.1 Upon the death of a Participant or Vested Former  Participant,
while employed by the  Corporation  or an Affiliate,  who has completed at least
ten years of Credited  Service  with the  Corporation  or an  Affiliate  and has
attained age 55, his Surviving  Spouse will be entitled to a Surviving  Spouse's
Benefit under this Plan equal to 50% of the  Retirement  Benefit that would have
been provided  from the Plan had the  Participant  or Vested Former  Participant
retired from the Corporation or an Affiliate with the Corporation's  consent, on
the date of his death.





              6.2 Upon the death of a Participant or Vested Former  Participant,
while employed by the  Corporation  or an Affiliate,  who has completed at least
five years of Credited  Service with the Corporation or an Affiliate and has not
attained age 55, his Surviving  Spouse will be entitled to a Surviving  Spouse's
Benefit under this Plan equal to 50% of the  Retirement  Benefit that would have
been provided  from the Plan had the  Participant  or Vested Former  Participant
terminated  employment  with the  Corporation or an Affiliate on the date of his
death with the  Corporation's  consent,  and  elected to have the payment of his
Basic Plan Benefit commence at age 55 in the form of a straight life annuity.
              6.3 Upon the death of a Vested Former  Participant while no longer
employed by the  Corporation  or an Affiliate,  who has not attained age 55, his
Surviving  Spouse will be entitled to a Surviving  Spouse's  Benefit  under this
Plan equal to 50% of the  Retirement  Benefit that would have been provided from
the Plan to the Vested Former Participant at age 55, taking into account whether
the Corporation consented to the termination.
              6.4 Upon the death of a Participant or Vested Former  Participant,
while employed by the  Corporation  or an Affiliate,  who has completed at least
five,  but less than ten years of Credited  Service with the  Corporation  or an
Affiliate  and has attained age 55, his  Surviving  Spouse will be entitled to a
Surviving  Spouse's  Benefit  under  this  Plan  equal to 50% of the  Retirement
Benefit  that  would have been  provided  from the Plan had the  Participant  or
Vested Former  Participant  terminated  employment  with the  Corporation  or an
Affiliate on the date of his death with the Corporation's  consent and his Basic
Plan Benefit commenced immediately in the form of a straight life annuity.
              6.5 Upon the  death of a  Vested  Former  Participant  while he is
receiving  Retirement  Benefits,  his Surviving Spouse shall receive a Surviving
Spouse's Benefit equal to 50% of the Retirement  Benefit he was receiving at the
time of his death.
              6.6 Except as  provided in Section  6.8,  the  Surviving  Spouse's
Benefit  provided under Section 6.1, 6.4 and 6.5 will be payable  monthly,  will
commence as of the first day of the month  coincident with or next following the
month in which the  Participant  or Vested  Former  Participant  dies,  and will
continue until the first day of the month in which the Surviving Spouse dies.
              6.7 Except as  provided in Section  6.8,  the  Surviving  Spouse's
Benefit  provided  under  Section  6.2 and 6.3  will be  payable  monthly,  will
commence as of the first day of the month  coincident with or next following the
month in which the Participant or Vested Former  Participant would have attained
age 55,  and will  continue  until  the  first  day of the  month  in which  the
Surviving Spouse dies.
              6.8 (a) If a Participant or a Vested Former  Participant  while he
was a Participant  has made an Election under Section 4.5 or a Special  Election
under Section 4.6 and such Election or Special Election is effective on the date
of such  Participant's  or Vested  Former  Participant's  death,  the  Surviving
Spouse's  Benefit  payable to a Surviving  Spouse of such  Participant or Vested
Former  Participant  will be  payable  in the  form or  combination  of forms of
payment so elected by such Participant or Vested Former Participant  pursuant to
such Election or Special Election. The amount of any lump sum payment under this
Section  6.8  shall  be the  present  value  of the  applicable  portion  of the
Surviving  Spouse's Benefit payable under the Plan, and such present value shall
be determined using the actuarial  assumptions set forth in Section 4.5(a).  Any
lump sum distribution of a Surviving  Spouse's  Surviving Spouse's Benefit under
the Plan shall fully satisfy all present and future Plan  liability with respect
to such  Surviving  Spouse for such  portion or all of such  Surviving  Spouse's
Benefit so distributed.
     (b) Notwithstanding any Election or Special Election made under Section 4.5
or 4.6, if the lump sum value,  determined in the same manner as provided  under
Section 4.5(a),  of a Surviving  Spouse's Benefit is $10,000 or less at the time
such Surviving  Spouse's  Benefit is payable under this Plan, such benefit shall
be payable as a lump sum.
     (c) Any portion of a Surviving Spouse's Benefit provided under Section 6.1,
6.4 and 6.5 which is payable  as an  annuity  shall be paid in the manner and at
such time as set forth in Section 6.6, and any such benefit  which is payable as
a lump sum shall be paid 60 days after the date when annuity payments  commence,
or would commence if any portion of such Surviving Spouse's Benefit were payable
as an annuity as set forth in Section 6.6.





     (d) Any portion of a Surviving  Spouse's Benefit provided under Section 6.2
and 6.3 which is payable  as an annuity  shall be paid in the manner and at such
time as set forth in Section  6.7,  and any such  benefit  which is payable as a
lump sum shall be paid 60 days after the date when annuity payments commence, or
would commence if any portion of such Surviving Spouse's Benefit were payable as
an annuity, as set forth in Section 6.7.
              6.9  Notwithstanding  the  foregoing  provisions of Section 6, the
amount of a Surviving  Spouse's Benefit shall be reduced by one percentage point
for each year  (including  a half year or more as a full  year) in excess of ten
that the age of the Participant or Vested Former Participant  exceeds the age of
the Surviving Spouse.

                                    SECTION 7
                                    Committee
              7.1 The Committee shall be responsible for the  administration  of
the Plan and may delegate to any  management  committee,  employee,  director or
agent  its  responsibility  to  perform  any act  hereunder,  including  without
limitation  those matters  involving the exercise of  discretion,  provided that
such  delegation  shall be subject to revocation at any time at its  discretion.
The Committee  shall have the authority to interpret the  provisions of the Plan
and  construe  all  of its  terms,  to  adopt,  amend,  and  rescind  rules  and
regulations  for the  administration  of the Plan,  and generally to conduct and
administer the Plan and to make all  determinations  in connection with the Plan
as may be necessary or  advisable.  All such actions of the  Committee  shall be
conclusive and binding upon all Participants, Former Participants, Vested Former
Participants and Surviving Spouses.






                                    SECTION 8
                                  Miscellaneous
              8.1 The Board may, in its sole discretion,  terminate,  suspend or
amend this Plan at any time or from time to time, in whole or in part.  However,
no  termination,  suspension  or  amendment of the Plan may  adversely  affect a
Participant's or Vested Former Participant's vested benefit under the Plan, or a
retired  Participant's  or Vested Former  Participant's  right or the right of a
Surviving  Spouse to receive or to continue  to receive a benefit in  accordance
with the Plan as in effect on the date  immediately  preceding  the date of such
termination, suspension or amendment.
              8.2 Nothing  contained  herein  will confer upon any  Participant,
Former  Participant or Vested Former Participant the right to be retained in the
service of the  Corporation  or any  Affiliate,  nor will it interfere  with the
right of the  Corporation  or any Affiliate to discharge or otherwise  deal with
Participants,  Former Participants or Vested Former Participants with respect to
matters of employment without regard to the existence of the Plan.
              8.3 Notwithstanding  anything herein to the contrary,  at any time
following  the  termination  of  service  of  a  Participant  or  Vested  Former
Participant,  the Committee may authorize, under uniform rules applicable to all
Participants, Vested Former Participants and Surviving Spouses under the Plan, a
lump sum distribution of a  Participant's,  Vested Former  Participant's  and/or
Surviving  Spouse's  Retirement  Benefit or Surviving Spouse's Benefit under the
Plan in an amount  equal to the  present  value of such  Retirement  Benefit  or
Surviving  Spouse's  Benefit,  using the actuarial  assumptions  then in use for
funding purposes under The Dun & Bradstreet  Corporation  Retirement Account, in
full  satisfaction of all present and future Plan liability with respect to such
Participant, Vested Former Participant and/or Surviving Spouse, if the amount of
such present value is less than $250,000. Such lump sum distribution may be made
without the consent of the Participant,  Vested Former  Participant or Surviving
Spouse.





              8.4 (a) Notwithstanding  anything in this Plan to the contrary, if
a  Participant  has less than five  years of  Credited  Service at the time of a
Change in  Control,  and as a result of the  Change in  Control,  and  before he
completes five years of Credited Service,  (i) the Plan is terminated,  (ii) the
Participant  is removed from  further  participation  in the Plan,  or (iii) the
Participant is terminated as a result of action initiated directly or indirectly
by the  Corporation or any Affiliate,  such  Participant  shall be entitled to a
Benefit of 20% of his Average Final Compensation and the Corporation will remain
obligated to pay all benefits under the Plan.
     (b)  Notwithstanding  anything  in this  Plan  to the  contrary,  upon  the
occurrence  of a  Change  in  Control,  (i) no  reduction  shall  be  made  in a
Participant's or Vested Former Participant's Retirement Benefit, notwithstanding
his  termination  of  employment  or  Retirement  prior  to age 60  without  the
Corporation's  consent, (ii) the provisions of Section 3.3(i) and (ii) shall not
apply to any Participant,  Vested Former Participant or Surviving Spouse,  (iii)
each Participant and Vested Former  Participant  already  receiving a Retirement
Benefit  under the Plan  shall  receive a lump sum  distribution  of his  unpaid
Retirement  Benefit and, if he is married,  his Surviving Spouse's Benefit under
the Plan  within 30 days of the  Change  of  Control  in an amount  equal to the
present value of such Retirement  Benefit and Surviving Spouse's Benefit in full
satisfaction  of all  present  and future Plan  liability  with  respect to such
Participant,  Vested Former  Participant and Surviving  Spouse, if any, and each
Surviving Spouse already  receiving a Surviving  Spouse's Benefit under the Plan
shall receive a lump sum distribution of his unpaid  Surviving  Spouse's Benefit
at the same  time in an  amount  equal to the  present  value of such  Surviving
Spouse's  Benefit  in full  satisfaction  of Plan  liability  to such  Surviving
Spouse,  (iv) each Vested  Former  Participant  who is not  already  receiving a
Retirement  Benefit under the Plan shall receive a lump sum  distribution of his
unpaid Retirement Benefit and, if he is married,  his Surviving Spouse's Benefit
within 30 days of the Change in Control in an amount equal to the present  value
of such Retirement  Benefit and Surviving  Spouse's Benefit,  and each Surviving
Spouse of either a Vested Former  Participant or a Participant with five or more
years of  Credited  Service who is not  already  receiving a Surviving  Spouse's
Benefit  under the Plan  shall  receive a lump sum  distribution  of his  unpaid
Surviving Spouse's Benefit at the same time in amount equal to the present value
of such Surviving  Spouse's  Benefit,  (v) each  Participant with less than five
years of Credited  Service who is entitled  to a benefit  under  Section  8.4(a)
shall receive a lump sum  distribution  of the present value of such  Retirement
Benefit within 30 days from the earlier of the date the Plan is terminated,  the
date he is  removed  from  further  participation  in the Plan,  or the date his
employment  with the  Corporation is terminated,  and of his Surviving  Spouse's
Benefit based upon the amount of such Retirement Benefit if he is married on the
applicable  date, and (vi) each Participant who is not included in (v) above and
who is not already  receiving a Retirement  Benefit under the Plan shall receive
(a)  within 30 days of the later to occur of the date of such  Change in Control
or the date he completes five years of Credited  Service a lump sum distribution
of the present value of his accrued  Retirement Benefit under the Plan as of the
applicable  date and, if he is married on such date,  the  present  value of his
Surviving Spouse's Benefit, and (b) within 30 days from the earliest of the date
of his Retirement or termination of employment  with the  Corporation,  the date
the Plan is terminated or the date he is removed from further  participation  in
the  Plan,  a lump sum  distribution  of the  present  value  of his  additional
Retirement  Benefit accrued after the applicable event in (a) computed as of the
applicable date herein set forth in (b) and, if he is married on such applicable
date, the present value of his surviving  Spouse's  Benefit.  In determining the
amount of the lump sum  distributions  to be paid under this  Section  8.4,  the
following actuarial  assumptions shall be used: (i) the interest rate used shall
be the  interest  rate used by the  Pension  Benefit  Guaranty  Corporation  for
determining  the value of  immediate  annuities  as of January 1st of either the
year of the occurrence of the Change in Control or the participant's  retirement
or  termination  of  employment,  whichever is  applicable,  (ii) the 1983 Group
Annuity  Mortality  Table shall be used;  and (iii) it shall be assumed that all
participants  retired or terminated  employment with the Corporation on the date
of the  occurrence of the Change in Control and with the  Corporation's  consent
for purposes of determining  the amount of the lump sum  distribution to be paid
upon the occurrence of the Change in Control.




              8.5 (a) The Plan is unfunded,  and the Corporation  will make Plan
benefit payments solely on a current disbursement basis, provided, however, that
the Corporation reserves the right to purchase insurance contracts, which may or
may  not be in the  name of a  Participant  or  Vested  Former  Participant,  or
establish one or more trusts to provide  alternative sources of benefit payments
under this Plan,  provided,  further,  however,  that upon the  occurrence  of a
"Potential  Change in Control" the  appropriate  officers of the Corporation are
authorized to make such  contributions  to such trust or trusts as are necessary
to fund the lump sum  distributions to Plan  participants  required  pursuant to
Section 8.4 of this Plan in the event of a Change in Control. In determining the
amount of the  necessary  contribution  to the trust or trusts in the event of a
Potential Change in Control, the following actuarial  assumptions shall be used:
(i) the  interest  rate used  shall be the  interest  rate  used by the  Pension
Benefit Guaranty Corporation for determining the value of immediate annuities as
of January 1st of the year of the occurrence of the Potential Change in Control,
(ii) the 1983 Group Annuity Mortality Table shall be used; and (iii) it shall be
assumed  that all  participants  will retire or  terminate  employment  with the
Corporation as soon as practicable  after the occurrence of the Potential Change
in  Control  and with  the  Corporation's  consent.  The  existence  of any such
insurance  contracts,  trust or trusts shall not relieve the  Corporation of any
liability  to make  benefit  payments  under  this  Plan,  but to the extent any
benefit  payments are made from any such  insurance  contract in the name of the
Corporation  or any  Affiliate or from any such trust,  such payment shall be in
satisfaction of and shall reduce the Corporation's  liabilities under this Plan.
Further,  in the  event  of the  Corporation's  bankruptcy  or  insolvency,  all
benefits accrued under this Plan shall  immediately  become due and payable in a
lump sum and all Participants,  Vested Former Participants and Surviving Spouses
shall be entitled to share in the Corporation's assets in the same manner and to
the same extent as general unsecured creditors of the Corporation.




              8.5 (b) Members and Vested Former Members shall have the status of
general unsecured  creditors of the Corporation and this Plan constitutes a mere
promise  by the  Corporation  to make  benefit  payments  at the  time or  times
required  hereunder.  It is the intention of the  Corporation  that this Plan be
unfunded for tax purposes and for purposes of Title I of the Employee Retirement
Income Security Act of 1974, as amended and any trust created by the Corporation
and any assets held by such trust to assist the  Corporation and any assets held
by such trust to assist the Corporation in meeting it obligations under the Plan
shall meet the requirements necessary to retain such unfunded status.
     8.6 If any dispute  arises  under the Plan  between the  Corporation  and a
Participant,  Former Participant,  Vested Former Participant or Surviving Spouse
(collectively or individually  referred to as "Participant" in this Section 8.6)
as to the amount or timing of any  benefit  payable  under the Plan or as to the
persons entitled thereto,  such dispute shall be resolved by binding arbitration
proceedings  initiated  by either  party to the dispute in  accordance  with the
rules  of  the  American  Arbitration   Association  and  the  results  of  such
proceedings  shall be  conclusive  on both  parties  and shall not be subject to
judicial review.  If the disputed benefits involve the benefits of a Participant
who is no longer employed by the  Corporation or any Affiliate,  the Corporation
shall pay or continue to pay the benefits  claimed by the Participant  until the
results of the  arbitration  proceedings  are  determined  unless  such claim is
patently  without  merit;  provided,   however,  that  if  the  results  of  the
arbitration  proceedings are adverse to the Participant,  then in such event the
recipient of the benefits shall be obligated to repay the excess benefits to the
Corporation.  The Corporation  expressly  acknowledges  that the amounts payable
under the Plan are necessary to the livelihood of Participants  and their family
members  and that any  refusal or neglect to pay  benefits  under the  preceding
sentence prior to the resolution of any dispute shall be prima facie evidence of
bad faith on its part and will be conclusive  grounds for an  arbitration  award
resulting  in  an  immediate  lump  sum  payment  to  the  Participant,  of  the
Participant's  benefits  under the Plan then due and payable to him,  unless the
arbitrator  determines  that the claim for the  disputed  benefits  was  without
merit.

The amount of such lump sum payment shall be equal to the then  actuarial  value
of such benefits  calculated by utilizing the actuarial  assumptions then in use
for funding purposes under The Dun & Bradstreet  Corporation Retirement Account.
In  addition,  in the  event of any  dispute  covered  by this  Section  8.6 the
Corporation  agrees to pay the entire  costs of any  arbitration  proceeding  or
legal proceeding brought  hereunder,  including the fees and expenses of counsel
and pension  experts  engaged by a Participant  and that such expenses  shall be
reimbursed  promptly upon evidence that such expenses have been incurred without
awaiting the outcome of the arbitration  proceedings;  provided,  however,  that
such costs and expenses  shall be repaid to the  Corporation by the recipient of
same if it is finally  determined by the arbitrators  that the position taken by
such person was without merit.
              8.7 To the maximum  extent  permitted by law, no benefit under the
Plan shall be assignable or subject in any manner to alienation, sale, transfer,
claims of creditors, pledge, attachment or encumbrances of any kind.
              8.8 The  Corporation  may withhold from any benefit under the Plan
an amount sufficient to satisfy its tax withholding obligations.
              8.9 The Plan is established under and will be construed according 
to the laws of the State of New York.
