Re:    Equity Commitment Letter

Ladies and Gentlemen:

Reference is made to the Agreement and Plan of Merger, dated as of the date
hereof (as amended, restated, modified or supplemented from time to time, the
“Merger Agreement”), by and among The Dun & Bradstreet Corporation, a Delaware
corporation (the “Company"), Star Parent, L.P., a Delaware limited partnership
(“Parent”) and Star Merger Sub, Inc., a Delaware corporation and wholly owned
subsidiary of Parent (“Merger Sub”), pursuant to which Merger Sub will merge
with and into the Company, with the Company as the surviving corporation (the
“Merger”). Capitalized terms used but not otherwise defined herein have the
meanings ascribed to such terms in the Merger Agreement. Cannae Holdings, Inc.,
a Delaware corporation, is referred to herein as the “Equity Investor.” This
letter is being delivered by the Equity Investor to Parent in connection with
the execution of the Merger Agreement.

1.Commitment. This letter confirms the commitment of the Equity Investor,
subject to the terms and conditions set forth herein, to purchase, directly or
indirectly (or cause an assignee permitted by the terms of Section 4(a) hereto
to purchase), at or immediately prior to Closing, for an aggregate cash purchase
price equal to $900,000,000.00 (such commitment, the “Equity Commitment”),
common equity interests of Parent (collectively, the “Subject Equity
Securities”). The Equity Commitment shall only be used by Parent, to the extent
necessary, to fund, directly or indirectly, together with the proceeds of the
Debt Financing and Preferred Financing and the proceeds of the other equity
commitment letters (collectively, the “Other Equity Commitments”) from other
investors (each, an “Other Equity Investor”) to Parent of even date herewith
(each, as amended from time to time, an “Other Equity Commitment Letter”): (i)
Parent’s payment obligations under Article IV of the Merger Agreement (including
the payment of the aggregate Per Share Merger Consideration) and (ii) related
fees, costs and expenses required to be paid by Parent, Merger Sub or the
Surviving Corporation, in each case, in connection with the transactions
contemplated by the Merger Agreement and pursuant to and in accordance with the
Merger Agreement (clauses (i) and (ii) collectively, the “Transaction Costs”),
and for no other purposes. The Equity Investor shall not, under any
circumstances, be obligated pursuant to this letter to contribute to Parent more
than the Equity Commitment. In the event that, after taking into account funds
available from other sources at Closing, Parent does not require the full amount
of the Equity Commitment in order to consummate the Merger and perform its
obligations under the Merger Agreement, the amount to be funded under this
letter agreement will be reduced by such amount that is not so required by
Parent. Notwithstanding anything to the contrary set forth herein, in no event
will the cumulative liability of the Equity Investor under this letter exceed
the amount of the Equity Commitment.

2.Conditions. The obligation of the Equity Investor (or any of its permitted
assigns) to fund

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

the Equity Commitment is subject to (i) the execution and delivery of the Merger
Agreement by the Company, Parent and Merger Sub, (ii) the satisfaction or waiver
of all of the conditions

to Parent’s and Merger Sub’s obligations to effect the Closing set forth in
Sections 7.1 and 7.2 of the Merger Agreement (other than those conditions that
by their nature are to be satisfied by actions taken at the Closing (but subject
to such conditions being satisfied at the Closing)), (ii) the substantially
simultaneous consummation of the Closing in accordance with the terms of the
Merger Agreement and
(iii) the substantially simultaneous funding of the Debt Financing and Preferred
Financing or Alternative Financing.

3.Limited Guarantee. Concurrently with the execution and delivery of this
letter,
(i)the Equity Investor is executing and delivering to the Company a Limited
Guarantee (as amended from time to time, the “Equity Investor Limited
Guarantee”) relating to certain of Parent’s obligations under the Merger
Agreement and (ii) each of the Other Equity Investors is executing and
delivering to the Company a Limited Guarantee (each, as amended from time to
time, an “Other Equity Investor Limited Guarantee” and collectively with the
Equity Investor Limited Guarantee and all Other Equity Investor Limited
Guarantees, the “Limited Guarantees”) relating to certain of Parent’s
obligations under the Merger Agreement. Except as expressly set forth in Section
7(b) hereof, the Company’s remedies against the Equity Investor under the Equity
Investor Limited Guarantee with respect to any Non-Prohibited Claims shall, and
are intended to, be the sole and exclusive direct or indirect remedies available
to the Company and its Affiliates against the Equity Investor or any
Non-Recourse Party for any liability, loss, damage or recovery of any kind
(including special, exemplary, consequential, indirect or punitive damages or
damages arising from loss of profits, business opportunities or goodwill,
diminution in value or any other losses or damages, whether at law, in equity,
in contract, in tort or otherwise) arising under or in connection with any
breach of, or liabilities or obligations arising under or in connection with,
this letter, the Merger Agreement, the Equity Investor Limited Guarantee
(whether willfully, intentionally, unintentionally or otherwise) or of the
failure of the transactions contemplated by the Merger Agreement to be
consummated for any reason or otherwise in connection with the transactions
contemplated hereby or by the Merger Agreement or in respect of any oral
representations made or alleged to have been made in connection therewith,
including in the event Parent breaches its obligations under the Merger
Agreement (whether or not a Parent breach is caused by the breach by the Equity
Investor of its obligations under this letter). Notwithstanding anything to the
contrary contained herein or in the Equity Investor Limited Guarantee, under no
circumstance shall the Company be permitted or entitled to receive both (a) a
grant of specific performance hereunder or under the Merger Agreement to cause
the Closing to occur or to cause Parent to enforce this letter and (b) payment
of the Parent Termination Fee or any monetary damages.

4.Termination. The Equity Investor’s obligation to fund the Equity Commitment
will terminate automatically and immediately upon the earliest to occur of: (a)
the discharge of the obligations of the Equity Investor hereunder in connection
with the Closing; (b) termination of the Merger Agreement in accordance with its
terms; (c) the assertion, directly or indirectly, of any claim, demand,
complaint, suit, arbitration, litigation or other Action, or the commencement of
any action, suit, proceeding or other Action, in each case, by the Company or
any of its Affiliates or Representatives (or any Person claiming by, through or
for the benefit of any of the foregoing) against the Equity Investor, Parent or
any Non-Recourse Party (as defined below) relating to this letter, any Limited
Guarantee, the Merger Agreement or any of the transactions contemplated hereby
or thereby (including in respect of any oral representations made or alleged to
be made in connection therewith), in each case, other than any claim by the
Company (i) against Parent seeking only specific performance against Parent in
accordance with the Merger Agreement or pursuant to Section 7(b) hereof with
respect to the Equity Investor’s obligation to fund its Equity Commitment in
accordance with, and solely to the extent permitted under, the terms hereof,
(ii) against the Equity Investor solely in accordance with and subject to the
terms and conditions of the Equity Investor Limited Guarantee or (iii) seeking
specific performance or injunctive relief to enforce the terms of the Mutual
Non-Disclosure Agreement between the Company and CC Capital Partners, LLC dated
as of May 29, 2018 as amended and restated July 23, 2018 in accordance
with the terms thereof (the foregoing clauses (i), (ii) and (iii), the
“Non-Prohibited Claims”); (d) any judgment against any of Parent or the Equity
Investor with respect to any Non-Prohibited Claim that includes an award for
money damages; and (e) the funding by the Equity Investor or any permitted
assignee(s) of the Equity Commitment hereunder (or such lesser amount pursuant
to the penultimate sentence of Section 1 hereto) in full to Parent. Upon

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

termination of this letter, the Equity Investor shall not have any further
obligations or liabilities hereunder.

5.
Assignment; Amendments and Waivers; Entire Agreement.

(a)The rights and obligations under this letter may not be assigned or delegated
(whether by operation of law, merger, consolidation or otherwise) by any party
hereto without the prior written consent of the other party, and any attempted
assignment shall be null and void and of no force or effect. Notwithstanding the
foregoing, the Equity Investor may assign and delegate all or a portion of its
obligations to fund the Equity Commitment to one or more co-investment vehicles
or investment funds that are sponsored, managed, advised or controlled by an
Affiliate of the Equity Investor or to other co- investors (which other
co-investors would not be reasonably expected to prevent, materially delay or
materially impair the ability of any of the parties to the Merger Agreement to
consummate the Merger or the other transactions contemplated by the Merger
Agreement); provided, however, that no such assignment shall relieve the Equity
Investor of its obligations hereunder (including its obligation to fund its full
Equity Commitment hereunder) and Parent shall be entitled to pursue all rights
and remedies against the Equity Investor subject to the terms and conditions
hereof.

(b)This letter may not be amended, and no provision hereof waived or modified,
except by an instrument signed by each of the parties hereto; provided, that no
amendment or modification of this letter shall adversely affect the rights of
the Company hereunder without the prior consent of the Company.

(c)Together with the Merger Agreement, the Limited Guarantees, the Other Equity
Commitment Letters and the other agreements and instruments contemplated hereby
or thereby, this letter constitutes the entire agreement and supersedes all
prior agreements and understandings, both written and oral, among or between any
of the parties with respect to the subject matter hereof and thereof.

6.No Third Party Beneficiaries. Except to the extent expressly set forth in
Sections 7(a) and 7(b), this letter shall be binding solely on, and inure solely
to the benefit of, the parties hereto and their respective successors and
permitted assigns, and nothing set forth in this letter shall be construed to
confer upon or give to any Person, other than the parties hereto and their
respective successors and permitted assigns, any benefits, rights or remedies
under or by reason of, or any rights to enforce or cause Parent to enforce, the
Equity Commitment or any provisions of this letter; provided, however, that (a)
Non-Recourse Parties are express, intended third party beneficiaries of Section
7(a) and may rely on and enforce the provisions of Section 7(a) and (b) the
Company is an express intended third party beneficiary of Section 7(b) hereto to
the extent expressly set forth therein.

7.
Limited Recourse; Enforcement.

(a)Notwithstanding anything that may be expressed or implied in this letter or
any document or instrument delivered in connection herewith, Parent, by its
acceptance of the benefits of the Equity Commitment provided herein, covenants,
agrees and acknowledges that no Person other than the Equity Investor shall have
any liability, obligation or commitment of any nature, known or unknown, whether
due or to become due, absolute, contingent or otherwise, hereunder or in
connection with the transactions contemplated hereby and that, notwithstanding
that the Equity Investor or any of its
permitted assigns may be a partnership or limited liability company, Parent has
no remedy or rights of recovery, and no recourse, hereunder or under any
documents or instruments delivered in connection herewith or in respect of any
oral representations made or alleged to have been made in connection herewith or
therewith against, or contribution from, any of the Equity Investor’s former,
current, or future directors, officers, employees, agents, general or limited
partners, managers, members, stockholders, holders of equity, controlling
persons, Affiliates, representatives, assignees or any former, current or future
director, officer, employee, agent, general or limited partners, managers,
members, stockholders, holder of equity, controlling person, Affiliate,
representative or assignee of any of the foregoing (but not including Parent and
the Equity Investor, a “Non-Recourse Party” and together, the “Non-Recourse
Parties”), whether by or through attempted piercing of the corporate (or limited
liability company or limited partnership) veil, by or through a claim (whether
at law or equity or in tort, contract or otherwise) by or on behalf of the
Equity Investor against any Non-Recourse Party, by the enforcement of any
assessment or by any legal or

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

equitable proceeding, or by virtue of any applicable Law, or otherwise, it being
agreed and acknowledged that no personal liability whatsoever shall attach to,
be imposed on or otherwise be incurred by any Non-Recourse Party for any
obligations or commitments of the Equity Investor or any of its successors or
permitted assigns under this letter, under the Merger Agreement or under any
documents or instrument delivered in connection herewith or therewith, in
respect of any transaction contemplated hereby or thereby, including in the
event Parent or Merger Sub breaches its obligations under the Merger Agreement,
whether or not Parent’s or Merger Sub’s breach is caused by Equity Investor’s
breach of its obligations hereunder, or in respect of any oral representations
made or alleged to have been made in connection herewith or therewith or for any
claim (whether at law or equity or in tort, contract or otherwise) based on, in
respect of, or by reason of such obligations or their creation.

(b)Subject to the proviso in Section 6, this letter may be enforced only by
Parent, and none of Parent’s direct or indirect creditors nor any other Person
that is not a party to this letter shall have any right to enforce this letter
or to cause Parent to enforce this letter; provided, however, that
notwithstanding anything in this letter to the contrary and subject to the terms
and conditions of the Merger Agreement, including without limitation, Section
9.6(b) thereof, the Company (solely to the extent set forth in this proviso) is
hereby made an express, intended third party beneficiary of the rights granted
to Parent hereby solely for the purpose of seeking through an action of specific
performance the enforcement of Parent’s right to cause the Equity Investor to
fund the Equity Commitment hereunder if and only if the Company is entitled to
specific performance in accordance with Section 9.6(b) of the Merger Agreement
(and subject to the terms and conditions hereof) and for no other purpose
(including, without limitation, any claim for monetary damages hereunder or
under the Merger Agreement). Notwithstanding the foregoing, in no event shall
this letter be enforced by any Person unless each of the Other Equity
Commitments is being concurrently enforced by such Person.

warrants to Parent that:
