or

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

liability arising from the Exiting Investor’s failure to comply with the Interim
Investors Agreement prior to the date hereof or Section 2.9 of the Interim
Investors Agreement).
6.    Exiting Investor Expense Reimbursement. Upon the earlier of the date of
the termination of the Merger Agreement and the Closing, the Company will
reimburse, or cause to be reimbursed, in full, all reasonable out-of-pocket
costs and expenses (including all fees of legal and financial advisors) incurred
by the Exiting Investor in connection with the transactions contemplated by the
Merger Agreement, its Equity Commitment Letter, its Limited Guarantee, the
Interim Investors Agreement, this Agreement and any other document entered into
by the Exiting Investor and the Company in connection therewith.
7.    Certain Representations. Each of the Exiting Investor and Cannae hereby
represent and warrant that they have all right, title and interest to the rights
and obligations being assigned by them pursuant to this Agreement.
8.    No Breach by the Exiting Investor. The Exiting Investor hereby represents
and warrants to the Company that it has complied with its obligations under its
Equity Commitment Letter and Limited Guarantee and under the Interim Investors
Agreement. The Company hereby acknowledges and agrees that, for purposes of the
Interim Investors Agreement, there has been no Breach by the Exiting Investor on
or prior to the date hereof.
9.    Satisfaction of Syndication Obligations. The Exiting Investor hereby
acknowledges and agrees that all obligations of the Company to syndicate the
Existing Investor’s Commitment pursuant to the QIA Equity Side Letter, dated as
of August 8, 2018, by and among the Exiting Investor, the Company and HPS
Investment Partners, LLC have been satisfied by the entry into this Agreement,
and, except with respect to Section 6 herein, that the Exiting Investor shall
have no rights to receive any payments, equity or distributions made from or by
the Company or in respect of the Originating Sponsors or otherwise.
10.    Commitment Reduction. The Company, Cannae and the Investor hereby agree
that in no event shall the Investor’s aggregate Commitment to the Company be
equal to or greater than 20% (and shall in all cases be less than 20%) of the
aggregate equity capitalization of the Company. To the extent at any time prior
to the Closing it is determined that the Investor’s aggregate Commitment would
be equal to or greater than 20% of the aggregate equity capitalization of the
Company, the Assigned Commitment shall be reduced accordingly such that the
Investor’s aggregate Commitment is less than 20% of the aggregate equity
capitalization of the Company. For the avoidance of doubt, in no event will this
Section 9 amend, reduce, or alter the assignments and assumptions with respect
to the Exiting Investor in any respect, or any of the Exiting Investor’s rights
hereunder.
11.    Joinder to Interim Investors Agreement.
(a)    The Investor hereby joins the Interim Investors Agreement as an Investor
Party thereto with respect to a total Commitment amount of $375,000,000 (which
amount, for the avoidance of doubt, includes, and is not in addition to, its
assumption of the $250,000,000 Commitment amount of the Exiting Investor and its
assumption of the Assigned Commitment from Cannae). The Company hereby
acknowledges and agrees that all Commitment amounts and calculations based
thereon in the Interim Investors Agreement shall be revised to reflect the
Investor’s total Commitment amount hereunder, and the Investor and Cannae hereby
acknowledge and agree the same (in each case including that Cannae’s Commitment
amount for all purposes under the Interim

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

Investors Agreement shall be deemed reduced by the Assigned Commitment and shall
be $775,000,000). The Company and Lead Sponsors shall amend Schedule I to the
Interim Investors Agreement to reflect the updated Commitment amounts in
accordance with this Agreement (along with the addition of other Investors
and/or Commitments as agreed by the Lead Sponsors).
(b)    The Investor hereby acknowledges and agrees that for purposes of Section
2.14 of the Interim Investors Agreement it shall be deemed to owe a Pro Rata
Share equal to the portion its aggregate Commitment amount bears to the total
amount of Commitments of those Investors (as such term is defined in the Interim
Investors Agreement) who have delivered Limited Guarantees in connection with
the Interim Investors Agreement (including the Investor), which for the
avoidance of doubt is the aggregate Pro Rata Share the Investor has agreed to
assume pursuant to this Agreement under Cannae’s Limited Guarantee and the
Exiting Investor’s Limited Guarantee. The Company and the Investor agree that
all of the other Investors’ (as such term is defined in the Interim Investors
Agreement, including the Exiting Investor’s) Pro Rata Shares will be
proportionately reduced such that all Pro Rata Shares together equal 100%.
(c)    The Investor hereby acknowledges and agrees that the terms and conditions
referenced on Exhibit A to the Interim Investors Agreement shall be deemed to
refer to the terms and conditions set forth on Exhibit F hereto, subject to
changes as may be agreed by the Lead Sponsors in accordance with the terms
thereof.

SHALL BE INTERPRETED, CONSTRUED AND GOVERNED BY AND IN ACCORDANCE WITH THE LAW
OF THE STATE OF DELAWARE WITHOUT REGARD TO THE CONFLICTS OF LAW PRINCIPLES
THEREOF TO THE EXTENT THAT SUCH PRINCIPLES WOULD DIRECT A MATTER TO ANOTHER

the interpretation and enforcement of the provisions of (and any claim or cause
of action arising under or relating to) this letter and of the documents
referred to in this letter, and in respect of the transactions contemplated

suit or proceeding for the interpretation or enforcement hereof or of any such
document, that it is not subject thereto or that such action, suit or proceeding
may not be brought or is not maintainable in said courts or that the venue
thereof may not be appropriate or that this letter or any such document may not
be enforced in or by such courts, and the parties irrevocably agree that all
claims relating to such action, proceeding or transactions shall be heard and
determined in such courts. The parties hereby consent to and grant any such
court jurisdiction over the person of such parties and, to the extent permitted
by Law, over the subject matter of such dispute and agree that mailing of
process or other papers in connection with any such action or proceeding in the
manner provided in Section 9.7 of the Merger Agreement or in such other manner
as may be permitted by Law shall be valid and sufficient service thereof; and
(b)        EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY
ARISE UNDER THIS AGREEMENT IS LIKELY TO INVOLVE

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

COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE EACH SUCH PARTY HEREBY
IRREVOCABLY AND UNCONDITIONALLY WAIVES TO THE FULLEST EXTENT PERMITTED BY LAW

PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS LETTER OR
THE TRANSACTIONS CONTEMPLATED BY THIS LETTER (INCLUDING THE FINANCING). EACH
PARTY HEREBY CERTIFIES AND ACKNOWLEDGES THAT (i) NO REPRESENTATIVE, AGENT OR

more counterparts, all of which shall be considered one and the same instrument
and shall become effective when one or more counterparts have been signed by
each of the parties hereto and delivered to the other parties hereto; it being
understood and agreed that all parties hereto need not sign the same

Exiting Investor’s Equity Commitment Letter

EXECUTION VERSION

August 8, 2018

Star Parent, L.P.
1701 Village Center Circle
Las Vegas, NV 89134

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. QIA FIG Holding LLC, a
limited liability company established under the Qatar Financial center Authority
in the State of Qatar, 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 $250,000,000.00 (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

Exhibit C
Exiting Investor’s Limited Guarantee

EXECUTION VERSION

LIMITED GUARANTEE
LIMITED GUARANTEE, dated as of August 8, 2018 (this “Limited Guarantee”), by QIA
FIG Holding LLC, a limited liability company established under the Qatar
Financial Center Authority in the State of Qatar. (the “Guarantor”), in favor of
The Dun & Bradstreet Corporation, a Delaware corporation (the “Guaranteed
Party”).
1.     Limited Guarantee. To induce the Guaranteed Party to enter into 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 Guaranteed Party, 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”), the Guarantor, intending to be legally
bound, hereby unconditionally and irrevocably guarantees to the Guaranteed
Party, on the terms and conditions set forth herein, the due and punctual
observance, performance and discharge of 12.86% (the “Pro Rata Share”) of the
payment obligations of Parent to pay to the Guaranteed Party: (a) the Parent
Termination Fee when and only if the Parent Termination Fee becomes payable
pursuant to Section 8.5(c) of the Merger Agreement (the “Parent Fee
Obligations”), (b) the amounts described in the second sentence of Section
8.5(e)(i) of the Merger Agreement when and only if such amounts become payable
pursuant to Section 8.5(e)(i) of the Merger Agreement (the “Enforcement Costs”)
and (c) Parent Reimbursement Obligations described in sections 6.11(i), 6.15(f)
and 6.16(b) of the Merger Agreement when and only if such obligations become
payable pursuant to such sections of the Merger Agreement (the “Expense
Obligations” and, together with the Parent Fee Obligations and the Enforcement
Costs, collectively, the “Obligations”); provided, however, that in no event
shall the Guarantor’s liability for (x) the Parent Fee Obligations and the
Expense Obligations, in the aggregate, exceed the Guarantor’s Pro Rata Share of
the Parent Termination Fee and (y) the Enforcement Costs, which are payable by
Parent pursuant to Section 8.5(e)(i) of the Merger Agreement, in the aggregate,
exceed $643,241.55 (such limitation on the liability that the Guarantor may have
for the applicable Obligations as described in clause (x) or clause (y), as
applicable, being herein referred to as, the “Cap” for such relevant
Obligations). The parties agree that this Limited Guarantee may not be enforced
without giving effect to the Cap and that the Guaranteed Party will not seek to
enforce this Limited Guarantee for an amount in excess of the Cap (and giving
effect to the provisions of Section 8 and Section 9 hereof). This Limited
Guarantee may be enforced for the payment of money only in satisfaction of the
Obligations by the Guarantor up to the Cap. The Guaranteed Party hereby agrees
that (i) in no event shall the Guarantor be required to pay any amount to the
Guaranteed Party or any other Person under, in respect of, or in connection with
this Limited Guarantee or the Merger Agreement other than as expressly set forth
herein and (ii) in no event shall this Limited Guarantee be enforced by the
Guaranteed Party unless each Other Equity Investor Limited Guarantee (as defined
in the Guarantor’s Equity Commitment Letter) is being concurrently enforced by
the Guaranteed Party. All payments hereunder shall be made in lawful money of
the United States, in immediately available funds. Capitalized terms used but
not otherwise defined herein have the meanings ascribed to such terms in the
Merger Agreement.
If Parent fails to discharge all or any portion of the Obligations when due,
then to the extent expressly permitted in the Merger Agreement and this Limited
Guarantee, the Guarantor shall, on the Guaranteed Party’s demand, forthwith pay
to the Guaranteed Party the Obligations (subject to the terms and conditions

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

of the Limited Guarantee, including the Cap), and the Guaranteed Party may at
any time and from time to time, at the Guaranteed Party’s option, so long as the
Guarantor has failed to perform the Obligations, take any and all actions
available hereunder or under applicable Law to collect the Guarantor’s
liabilities hereunder in respect of such Guaranteed Obligations, subject to the
Cap.
2.     Nature of Limited Guarantee. The Guaranteed Party shall not be obligated
to file any claim relating to the Obligations in the event that Parent becomes
subject to a bankruptcy, reorganization or similar proceeding, and the failure
of the Guaranteed Party to so file shall not affect the Guarantor’s obligation
hereunder. In the event that any payment to the Guaranteed Party in respect of
the Obligations is rescinded or must otherwise be returned for any reason
whatsoever, the Guarantor shall remain liable hereunder with respect to the
Obligations (subject to the terms and conditions hereof) as if such payment had
not been made. This Limited Guarantee is an unconditional guarantee of payment
and not of collection. Notwithstanding any other provision of this Limited
Guarantee, the Guaranteed Party hereby agrees that the Guarantor may assert, as
a defense to any payment or performance by the Guarantor under this Limited
Guarantee, any defense to such payment or performance that Parent, Merger Sub or
any of their assigns may have under the terms of the Merger Agreement, other
than defenses arising from bankruptcy or insolvency of Parent.
3.     Changes in the Obligations; Certain Waivers. The Guarantor agrees that
the Guaranteed Party may at any time and from time to time, without notice to or
further consent of the Guarantor, extend the time of payment of the Obligations,
and may also enter into any agreement with Parent or any other Person interested
in the transactions contemplated by the Merger Agreement for the extension,
renewal, payment, compromise, discharge or release thereof, in whole or in part,
or for any modification of the terms of the Merger Agreement or of any agreement
between the Guaranteed Party, Parent and Merger Sub or any such other Person
without in any way impairing or affecting the Guarantor’s obligations under this
Limited Guarantee or the validity or enforceability of this Limited Guarantee,
provided that the obligations of the Other Equity Investors (as defined in the
Guarantor’s Equity Commitment Letter) under the Other Equity Investor Limited
Guarantees are impacted in substantially the same manner. Subject to the
termination of this Limited Guarantee as provided hereunder and the immediately
preceding sentence of this Section 3, the Guarantor agrees that the obligations
of the Guarantor hereunder shall not be released or discharged, in whole or in
part, or otherwise affected by (a) the failure or delay on the part of the
Guaranteed Party to assert any claim or demand or to enforce any right or remedy
against Parent or any other Person interested in the transactions contemplated
by the Merger Agreement; (b) any change in the time, place or manner of payment
of the Obligations or any waiver, compromise, consolidation or other amendment
or modification of any of the terms or provisions of the Merger Agreement; (c)
the addition, substitution or release of any entity or other Person interested
in the transactions contemplated by the Merger Agreement; (d) any change in the
corporate existence, structure or ownership of any of Parent or any other Person
interested in the transactions contemplated by the Merger Agreement; (e) any
insolvency, bankruptcy, reorganization or other similar proceeding affecting
Parent or any other Person (other than the Guaranteed Party and its
Subsidiaries) interested in the transactions contemplated by the Merger
Agreement or affecting any of their respective assets; (f) the existence of any
claim, set-off or other right which the Guarantor may have at any time against
Parent or the Guaranteed Party, whether in connection with the Obligations or
otherwise (other than those described in the last sentence of Section 2 hereof);
(g) the adequacy of any other means the Guaranteed Party may have of obtaining
payment of the Obligations; (h) the value, genuineness, validity, illegality or
enforceability of the Merger Agreement; or (i) any discharge of the Guarantor as
a matter of law or equity (other than as a result of the payment of the
Obligations in accordance with the terms hereof). To the fullest extent
permitted by applicable Law, the Guarantor hereby expressly waives any and all
rights or defenses arising by reason of any applicable Law which would otherwise
require any election of remedies by the Guaranteed Party. The Guarantor waives
promptness, diligence, notice of the acceptance of this Limited Guarantee and of
the Obligations, presentment, demand for payment, notice of non-performance,
default,

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

dishonor and protest, notice of the Obligations incurred and all other notices
of any kind (except for notices required to be provided to Parent and its
counsel in accordance with the Merger Agreement and/or any agreements entered
into in connection therewith), all defenses that may be available by virtue of
any valuation, stay, moratorium Law or other similar applicable Law now or
hereafter in effect, any right to require the marshalling of assets of Parent or
Merger Sub or any other Person interested in the transactions contemplated by
the Merger Agreement, and all suretyship defenses generally. The Guarantor
acknowledges that it will receive substantial direct and indirect benefits from
the transactions contemplated by the Merger Agreement and that the waivers set
forth in this Limited Guarantee are knowingly made in contemplation of such
benefits.
The Guaranteed Party hereby covenants and agrees that it shall not institute,
and shall cause its Subsidiaries and Affiliates and other representatives and
agents not to institute, any proceeding or bring any other claim arising under,
or in connection with, any Equity Commitment Letter or the Merger Agreement or
the transactions contemplated thereby, against the Guarantor or any other
Non-Recourse Party, except for claims that are Non-Prohibited Claims (as defined
in the Guarantor’s Equity Commitment Letter) against such Person, and the
Guarantor hereby covenants and agrees that it shall not institute, and shall
cause its respective Affiliates not to institute, any proceeding asserting that
this Limited Guarantee is illegal, invalid or unenforceable in accordance with
its terms. Notwithstanding anything to the contrary contained in this Limited
Guarantee, the Guaranteed Party hereby agrees that to the extent Parent is
relieved (other than by operation of any bankruptcy, insolvency or similar law)
of all or any portion of the Obligations under the Merger Agreement, the
Guarantor shall be similarly relieved of the Obligations under this Limited
Guarantee, with it being understood that such Obligations shall be relieved
ratably with the obligations of the Other Investors under the Other Equity
Investor Limited Guarantees.
Subject to the limitation on the Obligations set forth in the first sentence of
Section 1 hereof, the Guarantor hereby unconditionally and irrevocably agrees
not to exercise any rights that it may now have or hereafter acquire against
Parent or any other Person interested in the transactions contemplated by the
Merger Agreement that arise from the existence, payment, performance, or
enforcement of the Guarantor’s Obligations under or in respect of this Limited
Guarantee or any other agreement in connection therewith, including, without
limitation, any right of subrogation, reimbursement, exoneration, contribution
or indemnification and any right to participate in any claim or remedy of the
Guaranteed Party against Parent or such other Person whether or not such claim,
remedy or right arises in equity or under contract, statute or common law,
including, without limitation, the right to take or receive from Parent or such
other Person, directly or indirectly, in cash or other property or by set-off or
in any other manner, payment or security on account of such claim, remedy or
right, unless and until the Obligations (subject to the Cap) shall have been
paid in full in cash. If any amount shall be paid to the Guarantor in violation
of the immediately preceding sentence at any time prior to the payment in full
in cash of the Obligations, such amount shall be received and held in trust for
the benefit of the Guaranteed Party, shall be segregated from other property and
funds of the Guarantor and shall forthwith be paid or delivered to the
Guaranteed Party in the same form as so received (with any necessary endorsement
or assignment) to be credited and applied to the Obligations, in accordance with
the terms of the Merger Agreement, whether matured or unmatured, or to be held
as collateral for the Obligations. Notwithstanding any other provision of this
Limited Guarantee, in addition to any defense of the Guarantor on the basis of a
breach of this Limited Guarantee, the Guaranteed Party hereby agrees that the
Guarantor shall have all defenses to the payment of its obligations under this
Limited Guarantee (which in any event shall be subject to the Cap) that are or
would be available to Parent, Merger Sub or any of their assigns in respect of
the Merger Agreement with respect to the Obligations, as well as any defenses in
respect of any fraud.
4.     No Waiver; Cumulative Rights. No failure on the part of the Guaranteed
Party to exercise, and no delay in exercising, any right, remedy or power
hereunder shall operate as a waiver thereof, nor shall

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

any single or partial exercise by the Guaranteed Party of any right, remedy or
power hereunder preclude any other or future exercise of any right, remedy or
power hereunder. Each and every right, remedy and power hereby granted to the
Guaranteed Party shall be cumulative and not exclusive of any other, and may be
exercised by the Guaranteed Party at any time or from time to time.
5.     Representations and Warranties.
(a)The Guarantor hereby represents and warrants to the Guaranteed Party that:

(i)        the Guarantor has all requisite limited partnership or other entity
power and authority to execute, deliver and perform this Limited Guarantee and
the execution, delivery and performance of this Limited Guarantee by the
Guarantor have been duly authorized by all necessary action and do not
contravene any provision of the Guarantor’s charter, partnership agreement,
operating agreement or similar organizational documents or any applicable Law or
contractual restriction binding on the Guarantor or its assets;
(ii)        all consents, approvals, authorizations, permits of, filings with
and notifications to, any Governmental Entity necessary for the due execution,
delivery and performance of this Limited Guarantee by the Guarantor have been
obtained or made and all conditions thereof have been duly complied with, and no
other action by, and no notice to or filing with, any Governmental Entity is
required in connection with the execution, delivery or performance of this
Limited Guarantee;
(iii)    assuming due execution and delivery of the Merger Agreement by the
Guaranteed Party, Parent and Merger Sub, this Limited Guarantee constitutes a
legal, valid and binding obligation of the Guarantor enforceable against the
Guarantor in accordance with its terms, subject to (x) the effects of
bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium or
other similar applicable Laws affecting creditors’ rights generally, and (y)
general equitable principles (whether considered in a proceeding in equity or at
law); and
(iv)    the Guarantor has the financial capacity (taking into account all of its
outstanding commitments and obligations) to pay and perform its obligations
under this Limited Guarantee, and all funds necessary for the Guarantor to
fulfill the Obligations under this Limited Guarantee shall be available to the
Guarantor (and its assignees pursuant to Section 6 hereof) for so long as this
Limited Guarantee shall remain in effect in accordance with Section 8 hereof.
(b)The Guaranteed Party hereby represents and warrants to the Guarantor that:

(i)        it has all requisite corporate power and authority to execute,
deliver and perform this Limited Guarantee, and the execution, delivery and
performance of this Limited Guarantee has been duly authorized by all necessary
corporate action and does not contravene any provision of the Guaranteed Party’s
certificate of formation, limited liability company or operating agreement, or
any Law or contractual restriction applicable to or binding on the Guaranteed
Party or its assets; and
(ii)     assuming due execution and delivery of the Merger Agreement by Parent,
this Limited Guarantee constitutes a legal, valid and binding obligation of the
Guaranteed Party enforceable against the Guaranteed Party in accordance with its
terms, subject to (x) the effects of bankruptcy, insolvency, fraudulent
conveyance, reorganization, moratorium or other similar applicable Laws
affecting creditors’ rights generally, and (y) general equitable principles
(whether considered in a proceeding in equity or at law).

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

6.     Assignment. Neither the Guarantor nor the Guaranteed Party may assign
their respective rights, interests or obligations hereunder to any other Person
(including by operation of law) without the prior written consent of the
Guaranteed Party or the Guarantor, as the case may be. Notwithstanding the
foregoing, the Guarantor may assign its rights, interests or the Obligations
hereunder to one or more of its co-investment vehicles or affiliated investment
funds that are sponsored, managed or controlled by an Affiliate of the Guarantor
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 Guarantor of the Obligations hereunder except
that the Guarantor’s Obligations hereunder shall be reduced on a
dollar-for-dollar basis by any amounts actually paid to the Guaranteed Party in
respect of the Obligations hereunder by such co-investment vehicles or
affiliated investment funds or other co-investors.
7.     Notices. All notices, requests, claims, demands and other communications
hereunder shall be in writing and be given by the means specified in the Merger
Agreement (and shall be deemed given as specified therein) and shall be
delivered as set forth below or to such other Person or address or facsimile
number as a party to this Limited Guarantee shall specify by notice in writing
to the other party; provided that such notification shall only be effective on
the date specified in such notice or two (2) Business Days after the notice is
given, whichever is later.

8.     Continuing Guarantee. Unless terminated pursuant to this Section 8, this
Limited Guarantee shall remain in full force and effect and shall be binding on
the Guarantor, its successors and permitted assigns until the Obligations under
this Limited Guarantee have been paid in full, at which time this Limited
Guarantee shall terminate and the Guarantor shall have no further obligations
under this Limited Guarantee. Notwithstanding the foregoing, this Limited
Guarantee shall terminate and the Guarantor shall have no further obligations
under this Limited Guarantee as of the earliest to occur of (i) the Closing if
Parent shall have satisfied its payment obligations under Sections 4.1, 4.2(a)
and 4.3(d) of the Merger Agreement, (ii) at such time as the Obligations under
the Limited Guarantee have been paid in full (subject to the Cap),
(iii) termination of the Merger Agreement in circumstances in which the Parent
Termination Fee is not payable and (iv) sixty (60) days after the Termination
Date, except as to a claim for payment of the Obligations presented in writing
by the Guaranteed Party to Parent or the Guarantor on or prior to such sixtieth
(60th) day (in which case, this Limited Guarantee shall terminate on the date
such claim is (x) resolved by a final, non-appealable order of a court
specifically identified in Section 10(b) below, (y) resolved as agreed in
writing by the parties hereto or (z) otherwise satisfied); provided, that such
claim shall set forth in reasonable detail the basis for such claim, and the
Guarantor shall not be required to pay any claim not submitted on or before
sixty (60) days after such termination of the Merger Agreement. Notwithstanding
the foregoing, in the event that the Guaranteed Party or any of its Affiliates
asserts in any litigation or other proceeding (a) that the provisions of
Section 1 hereof limiting the Guarantor’s liability to the Cap, or limiting the
Guaranteed Party’s enforcement hereof to the payment of money only, or the
provisions of this Section 8 or Section 9 hereof are illegal, invalid or
unenforceable in whole or in part or (b) any theory of liability whatsoever
(whether at law or in equity, whether sounding in contract, tort, statute or
otherwise) against the Guarantor or any Non-Recourse Parties with respect to
this Limited Guarantee, the Equity Commitment Letters, the Merger Agreement or
any other agreement or instrument delivered pursuant to or in connection with
any of the foregoing (collectively, “Transaction Agreements”) 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) (other than,
solely with respect to this clause (b), any claim that is a Non-Prohibited Claim
against such Person), then (A) the obligations of the Guarantor under or in
connection with this Limited Guarantee shall terminate ab initio and be null and
void, (B) if the Guarantor has previously made any payments under this Limited
Guarantee, it shall be entitled to recover and retain such payments, and (C)
neither the Guarantor nor any Non-Recourse Parties shall have any liability
whatsoever (whether at law or in equity, whether sounding in contract, tort,
statute or otherwise) to the Guaranteed Party or any other Person in any way
under or in connection with any Transaction Agreement, any other agreement or
instrument delivered pursuant to such Transaction Agreement, or the transactions
contemplated hereby or thereby.
9.     No Recourse. The Guaranteed Party acknowledges the separate corporate
existence of Parent and that, as of the date hereof, Parent’s sole assets (if
any) are a de minimis amount of cash, and that no additional funds are expected
to be contributed to Parent unless and until the Closing occurs. Notwithstanding
anything that may be expressed or implied in this Limited Guarantee or any other
Transaction Agreement, or in any agreement, document or instrument (including,
without limitation, the Equity

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

Commitment Letters and the Merger Agreement), or statement made or action taken
in connection with or pursuant to, the transactions contemplated by any of the
Transaction Agreements or the negotiation, execution, performance or breach of
any Transaction Agreements, and notwithstanding any equitable, common law or
statutory right or claim that may be available to the Guaranteed Party or any of
its Affiliates, and notwithstanding the fact that the Guarantor may be a
partnership, by its acceptance of the benefits of this Limited Guarantee, the
Guaranteed Party covenants, acknowledges and agrees, on behalf of itself and its
Affiliates, (i) in no event shall the Guaranteed Party or any of its Affiliates
seek any damages or any other recovery, judgment, or remedies of any kind,
including consequential, indirect or punitive damages, against Parent in excess
of the Cap in connection with the Merger Agreement or in connection with the
failure of the transactions contemplated by the Merger Agreement to be
consummated for any reason or otherwise in connection with the transactions
contemplated thereby (including in respect of any oral representations made or
alleged to have been made in connection therewith), and (ii) notwithstanding the
fact that the Guarantor may be a corporation, partnership or limited liability
company, by its acceptance of the benefits of this Limited Guarantee, the
Guaranteed Party acknowledges and agrees that it has no right of recovery
against, no recourse shall be had against and no personal liability shall attach
to, the Guarantor or any of its former, current or future directors, officers,
employees, agents, general or limited partners, managers, members, stockholders,
holders of equity, controlling persons, Affiliates, representatives or assignees
or any former, current or future director, officer, employee, agent, general or
limited partner, manager, member, stockholder, holder of equity, controlling
person, Affiliate, representative or assignee of any of the foregoing (but not
including Parent or the Guarantor, a “Non-Recourse Party” and together, the
“Non-Recourse Parties”), including through Parent or otherwise, 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 in
tort, contract or otherwise) by or on behalf of Parent against the Guarantor or
any Non-Recourse Parties, by the enforcement of any assessment or by any legal
or equitable proceeding, by virtue of any applicable Law, or otherwise, except
for its rights to recover from the Guarantor (but not any other Person) under
and to the extent provided in this Limited Guarantee, and subject to the other
limitations described herein, including, for the avoidance of doubt, the Cap,
and any other claims that are Non-Prohibited Claims against such Person; it
being agreed and acknowledged that no personal liability whatsoever shall attach
to, be imposed on or otherwise be incurred by any Non-Recourse Parties for any
obligation of the Guarantor or any of its successors or permitted assigns under
this Limited Guarantee or any documents or instrument delivered in connection

Exhibit D
Cannae’s Equity Commitment Letter

EXECUTION VERSION

August 8, 2018

Star Parent, L.P.
c/o CC Capital
200 Park Ave., 58th Floor
New York, NY 10166

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.

8.Representations and Warranties. The Equity Investor hereby represents and
warrants to Parent that:

Exhibit E
Cannae’s Limited Guarantee

EXECUTION VERSION

LIMITED GUARANTEE

LIMITED GUARANTEE, dated as of August 8, 2018 (this “Limited Guarantee”), by
Cannae Holdings, Inc., a Delaware corporation (the “Guarantor”), in favor of The
Dun & Bradstreet Corporation, a Delaware corporation (the “Guaranteed Party”).

1.Limited Guarantee. To induce the Guaranteed Party to enter into 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
Guaranteed Party, 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”), the Guarantor, intending to be legally bound, hereby
unconditionally and irrevocably guarantees to the Guaranteed Party, on the terms
and conditions set forth herein, the due and punctual observance, performance
and discharge of 46.31% (the “Pro Rata Share”) of the payment obligations of
Parent to pay to the Guaranteed Party: (a) the Parent Termination Fee when and
only if the Parent Termination Fee becomes payable pursuant to Section 8.5(c) of
the Merger Agreement (the “Parent Fee Obligations”), (b) the amounts described
in the second sentence of Section 8.5(e)(i) of the Merger Agreement when and
only if such amounts become payable pursuant to Section 8.5(e)(i) of the Merger
Agreement (the “Enforcement Costs”) and (c) Parent Reimbursement Obligations
described in sections 6.11(i), 6.15(f) and 6.16(b) of the Merger Agreement when
and only if such obligations become payable pursuant to such sections of the
Merger Agreement (the “Expense Obligations” and, together with the Parent Fee
Obligations and the Enforcement Costs, collectively, the “Obligations”);
provided, however, that in no event shall the Guarantor’s liability for (x) the
Parent Fee Obligations and the Expense Obligations, in the aggregate, exceed the
Guarantor’s Pro Rata Share of the Parent Termination Fee and (y) the Enforcement
Costs, which are payable by Parent pursuant to Section 8.5(e)(i) of the Merger
Agreement, in the aggregate, exceed $2,315,669.59 (such limitation on the
liability that the Guarantor may have for the applicable Obligations as
described in clause (x) or clause (y), as applicable, being herein referred to
as, the “Cap” for such relevant Obligations). The parties agree that this
Limited Guarantee may not be enforced without giving effect to the Cap and that
the Guaranteed Party will not seek to enforce this Limited Guarantee for an
amount in excess of the Cap (and giving effect to the provisions of Section 8
and Section 9 hereof). This Limited Guarantee may be enforced for the payment of
money only in satisfaction of the Obligations by the Guarantor up to the Cap.
The Guaranteed Party hereby agrees that (i) in no event shall the Guarantor be
required to pay any amount to the Guaranteed Party or any other Person under, in
respect of, or in connection with this Limited Guarantee or the Merger Agreement
other than as expressly set forth herein and (ii) in no event shall this Limited
Guarantee be enforced by the Guaranteed Party unless each Other Equity Investor
Limited Guarantee (as defined in the Guarantor’s Equity Commitment Letter) is
being concurrently enforced by the Guaranteed Party. All payments hereunder
shall be made in lawful money of the United States, in immediately available
funds. Capitalized terms used but not otherwise defined herein have the meanings
ascribed to such terms in the Merger Agreement.

If Parent fails to discharge all or any portion of the Obligations when due,
then to the extent expressly permitted in the Merger Agreement and this Limited
Guarantee, the Guarantor shall, on the Guaranteed Party’s demand, forthwith pay
to the Guaranteed Party the Obligations (subject to the terms

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

and conditions of the Limited Guarantee, including the Cap), and the Guaranteed
Party may at any time and from time to time, at the Guaranteed Party’s option,
so long as the Guarantor has failed to perform the Obligations, take any and all
actions available hereunder or under applicable Law to collect the Guarantor’s
liabilities hereunder in respect of such Guaranteed Obligations, subject to the
Cap.

2.Nature of Limited Guarantee. The Guaranteed Party shall not be obligated to
file any claim relating to the Obligations in the event that Parent becomes
subject to a bankruptcy, reorganization or similar proceeding, and the failure
of the Guaranteed Party to so file shall not affect the Guarantor’s obligation
hereunder. In the event that any payment to the Guaranteed Party in respect of
the Obligations is rescinded or must otherwise be returned for any reason
whatsoever, the Guarantor shall remain liable hereunder with respect to the
Obligations (subject to the terms and conditions hereof) as if such payment had
not been made. This Limited Guarantee is an unconditional guarantee of payment
and not of collection. Notwithstanding any other provision of this Limited
Guarantee, the Guaranteed Party hereby agrees that the Guarantor may assert, as
a defense to any payment or performance by the Guarantor under this Limited
Guarantee, any defense to such payment or performance that Parent, Merger Sub or
any of their assigns may have under the terms of the Merger Agreement, other
than defenses arising from bankruptcy or insolvency of Parent.

3.Changes in the Obligations; Certain Waivers. The Guarantor agrees that the
Guaranteed Party may at any time and from time to time, without notice to or
further consent of the Guarantor, extend the time of payment of the Obligations,
and may also enter into any agreement with Parent or any other Person interested
in the transactions contemplated by the Merger Agreement for the extension,
renewal, payment, compromise, discharge or release thereof, in whole or in part,
or for any modification of the terms of the Merger Agreement or of any agreement
between the Guaranteed Party, Parent and Merger Sub or any such other Person
without in any way impairing or affecting the Guarantor’s obligations under this
Limited Guarantee or the validity or enforceability of this Limited Guarantee,
provided that the obligations of the Other Equity Investors (as defined in the
Guarantor’s Equity Commitment Letter) under the Other Equity Investor Limited
Guarantees are impacted in substantially the same manner. Subject to the
termination of this Limited Guarantee as provided hereunder and the immediately
preceding sentence of this Section 3, the Guarantor agrees that the obligations
of the Guarantor hereunder shall not be released or discharged, in whole or in
part, or otherwise affected by (a) the failure or delay on the part of the
Guaranteed Party to assert any claim or demand or to enforce any right or remedy
against Parent or any other Person interested in the transactions contemplated
by the Merger Agreement; (b) any change in the time, place or manner of payment
of the Obligations or any waiver, compromise, consolidation or other amendment
or modification of any of the terms or provisions of the Merger Agreement; (c)
the addition, substitution or release of any entity or other Person interested
in the transactions contemplated by the Merger Agreement; (d) any change in the
corporate existence, structure or ownership of any of Parent or any other Person
interested in the transactions contemplated by the Merger Agreement; (e) any
insolvency, bankruptcy, reorganization or other similar proceeding affecting
Parent or any other Person (other than the Guaranteed Party and its
Subsidiaries) interested in the transactions contemplated by the Merger
Agreement or affecting any of their respective assets; (f) the existence of any
claim, set-off or other right which the Guarantor may have at any time against
Parent or the Guaranteed Party, whether in connection with the Obligations or
otherwise (other than those described in the last sentence of Section 2 hereof);
(g) the adequacy of any other means the Guaranteed Party may have of obtaining
payment of the Obligations; (h) the value, genuineness, validity, illegality or
enforceability of the Merger Agreement; or (i) any discharge of the Guarantor as
a matter of law or equity (other than as a result of the payment of the
Obligations in accordance with the terms hereof). To the fullest extent
permitted by applicable Law, the Guarantor hereby expressly waives any and all
rights or defenses arising by reason of any applicable Law which would otherwise
require any election of remedies by the Guaranteed Party. The Guarantor waives

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

promptness, diligence, notice of the acceptance of this Limited Guarantee and of
the Obligations, presentment, demand for payment, notice of non-performance,
default, dishonor and protest, notice of the Obligations incurred and all other
notices of any kind (except for notices required to be provided to Parent and
its counsel in accordance with the Merger Agreement and/or any agreements
entered into in connection therewith), all defenses that may be available by
virtue of any valuation, stay, moratorium Law or other similar applicable Law
now or hereafter in effect, any right to require the marshalling of assets of
Parent or Merger Sub or any other Person interested in the transactions
contemplated by the Merger Agreement, and all suretyship defenses generally. The
Guarantor acknowledges that it will receive substantial direct and indirect
benefits from the transactions contemplated by the Merger Agreement and that the
waivers set forth in this Limited Guarantee are knowingly made in contemplation
of such benefits.

The Guaranteed Party hereby covenants and agrees that it shall not institute,
and shall cause its Subsidiaries and Affiliates and other representatives and
agents not to institute, any proceeding or bring any other claim arising under,
or in connection with, any Equity Commitment Letter or the Merger Agreement or
the transactions contemplated thereby, against the Guarantor or any other
Non-Recourse Party, except for claims that are Non-Prohibited Claims (as defined
in the Guarantor’s Equity Commitment Letter) against such Person, and the
Guarantor hereby covenants and agrees that it shall not institute, and shall
cause its respective Affiliates not to institute, any proceeding asserting that
this Limited Guarantee is illegal, invalid or unenforceable in accordance with
its terms. Notwithstanding anything to the contrary contained in this Limited
Guarantee, the Guaranteed Party hereby agrees that to the extent Parent is
relieved (other than by operation of any bankruptcy, insolvency or similar law)
of all or any portion of the Obligations under the Merger Agreement, the
Guarantor shall be similarly relieved of the Obligations under this Limited
Guarantee, with it being understood that such Obligations shall be relieved
ratably with the obligations of the Other Investors under the Other Equity
Investor Limited Guarantees.

Subject to the limitation on the Obligations set forth in the first sentence of
Section 1 hereof, the Guarantor hereby unconditionally and irrevocably agrees
not to exercise any rights that it may now have or hereafter acquire against
Parent or any other Person interested in the transactions contemplated by the
Merger Agreement that arise from the existence, payment, performance, or
enforcement of the Guarantor’s Obligations under or in respect of this Limited
Guarantee or any other agreement in connection therewith, including, without
limitation, any right of subrogation, reimbursement, exoneration, contribution
or indemnification and any right to participate in any claim or remedy of the
Guaranteed Party against Parent or such other Person whether or not such claim,
remedy or right arises in equity or under contract, statute or common law,
including, without limitation, the right to take or receive from Parent or such
other Person, directly or indirectly, in cash or other property or by set-off or
in any other manner, payment or security on account of such claim, remedy or
right, unless and until the Obligations (subject to the Cap) shall have been
paid in full in cash. If any amount shall be paid to the Guarantor in violation
of the immediately preceding sentence at any time prior to the payment in full
in cash of the Obligations, such amount shall be received and held in trust for
the benefit of the Guaranteed Party, shall be segregated from other property and
funds of the Guarantor and shall forthwith be paid or delivered to the
Guaranteed Party in the same form as so received (with any necessary endorsement
or assignment) to be credited and applied to the Obligations, in accordance with
the terms of the Merger Agreement, whether matured or unmatured, or to be held
as collateral for the Obligations. Notwithstanding any other provision of this
Limited Guarantee, in addition to any defense of the Guarantor on the basis of a
breach of this Limited Guarantee, the Guaranteed Party hereby agrees that the
Guarantor shall have all defenses to the payment of its obligations under this
Limited Guarantee (which in any event shall be subject to the Cap) that are or
would be available to Parent, Merger Sub or any of their assigns in respect of
the Merger Agreement with respect to the Obligations, as well as any defenses in
respect of any fraud.

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

4.No Waiver; Cumulative Rights. No failure on the part of the Guaranteed Party
to exercise, and no delay in exercising, any right, remedy or power hereunder
shall operate as a waiver thereof, nor shall any single or partial exercise by
the Guaranteed Party of any right, remedy or power hereunder preclude any other
or future exercise of any right, remedy or power hereunder. Each and every
right, remedy and power hereby granted to the Guaranteed Party shall be
cumulative and not exclusive of any other, and may be exercised by the
Guaranteed Party at any time or from time to time.

5.

respective rights, interests or obligations hereunder to any other Person
(including by operation of law) without the prior written consent of the
Guaranteed Party or the Guarantor, as the case may be. Notwithstanding the
foregoing, the Guarantor may assign its rights, interests or the Obligations
hereunder to one or more of its co-investment vehicles or affiliated investment
funds that are sponsored, managed or controlled by an Affiliate of the Guarantor

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 Guarantor of the Obligations hereunder except

8.Continuing Guarantee. Unless terminated pursuant to this Section 8, this
Limited Guarantee shall remain in full force and effect and shall be binding on
the Guarantor, its successors and permitted assigns until the Obligations under
this Limited Guarantee have been paid in full, at which time this Limited
Guarantee shall terminate and the Guarantor shall have no further obligations
under this Limited Guarantee. Notwithstanding the foregoing, this Limited
Guarantee shall terminate and the Guarantor shall have no further obligations
under this Limited Guarantee as of the earliest to occur of in full (subject to
the Cap), (iii) termination of the Merger Agreement in circumstances in which
the Parent Termination Fee is not payable and (iv) sixty (60) days after the
Termination Date, except as to a claim for payment of the Obligations presented
in writing by the Guaranteed Party to Parent or the Guarantor on or prior to
such sixtieth (60th) day (in which case, this Limited Guarantee shall terminate
on the date such claim is (x) resolved by a final, non-appealable order of a
court specifically identified in Section 10(b) below, (y) resolved as agreed in
writing by the parties hereto or (z) otherwise satisfied); provided, that such
claim shall set forth in reasonable detail the basis for such claim, and the
Guarantor shall not be required to pay any claim not submitted on or before
sixty (60) days after such termination of the Merger Agreement. Notwithstanding
the foregoing, in the event that the Guaranteed Party or any of its Affiliates
asserts in any litigation or other proceeding (a) that the provisions of Section
1 hereof limiting the Guarantor’s liability to the Cap, or limiting the
Guaranteed Party’s enforcement hereof to the payment of money only, or the
provisions of this Section 8 or Section 9 hereof are illegal, invalid or
unenforceable in whole or in part or (b) any theory of liability whatsoever
(whether at law or in equity, whether sounding in contract, tort, statute or
otherwise) against the Guarantor or any Non-Recourse Parties with respect to
this Limited Guarantee, the Equity Commitment Letters, the Merger Agreement or
any other agreement or instrument delivered pursuant to or in connection with
any of the foregoing (collectively, “Transaction Agreements”) 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) (other than,
solely with respect to this clause (b), any claim that is a Non-Prohibited Claim
against such Person), then (A) the obligations of the Guarantor under or in
connection with this Limited Guarantee shall terminate ab initio and be null and
void, (B) if the Guarantor has previously made any payments under this Limited
Guarantee, it shall be entitled to recover and retain such payments, and (C)
neither the Guarantor nor any Non-Recourse Parties shall have any liability
whatsoever (whether at law or in equity, whether sounding in contract, tort,
statute or otherwise) to the Guaranteed Party or any other Person in any way
under or in connection with any Transaction Agreement, any other agreement or
instrument delivered pursuant to such Transaction Agreement, or the transactions
contemplated hereby or thereby.

9.No Recourse. The Guaranteed Party acknowledges the separate corporate
existence of Parent and that, as of the date hereof, Parent’s sole assets (if
any) are a de minimis amount of cash, and that no additional funds are expected
to be contributed to Parent unless and until the Closing occurs. Notwithstanding
anything that may be expressed or implied in this Limited Guarantee or any other
Transaction Agreement, or in any agreement, document or instrument (including,
without limitation, the

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

Equity Commitment Letters and the Merger Agreement), or statement made or action
taken in connection with or pursuant to, the transactions contemplated by any of
the Transaction Agreements or the negotiation, execution, performance or breach
of any Transaction Agreements, and notwithstanding any equitable, common law or
statutory right or claim that may be available to the Guaranteed Party or any of
its Affiliates, and notwithstanding the fact that the Guarantor may be a
partnership, by its acceptance of the benefits of this Limited Guarantee, the
Guaranteed Party covenants, acknowledges and agrees, on behalf of itself and its
Affiliates, (i) in no event shall the Guaranteed Party or any of its Affiliates
seek any damages or any other recovery, judgment, or remedies of any kind,
including consequential, indirect or punitive damages, against Parent in excess
of the Cap in connection with the Merger Agreement or in connection with the
failure of the transactions contemplated by the Merger Agreement to be
consummated for any reason or otherwise in connection with the transactions
contemplated thereby (including in respect of any oral representations made or
alleged to have been made in connection therewith), and (ii) notwithstanding the
fact that the Guarantor may be a corporation, partnership or limited liability
company, by its acceptance of the benefits of this Limited Guarantee, the
Guaranteed Party acknowledges and agrees that it has no right of recovery
against, no recourse shall be had against and no personal liability shall attach
to, the Guarantor or any of its former, current or future directors, officers,
employees, agents, general or limited partners, managers, members, stockholders,
holders of equity, controlling persons, Affiliates, representatives or assignees
or any former, current or future director, officer, employee, agent, general or
limited partner, manager, member, stockholder, holder of equity, controlling
person, Affiliate, representative or assignee of any of the foregoing (but not
including Parent or the Guarantor, a “Non-Recourse Party” and together, the
“Non-Recourse Parties”), including through Parent or otherwise, 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 in
tort, contract or otherwise) by or on behalf of Parent against the Guarantor or
any Non-Recourse Parties, by the enforcement of any assessment or by any legal
or equitable proceeding, by virtue of any applicable Law, or otherwise, except
for its rights to recover from the Guarantor (but not any other Person) under
and to the extent provided in this Limited Guarantee, and subject to the other
limitations described herein, including, for the avoidance of doubt, the Cap,
and any other claims that are Non-Prohibited Claims against such Person; it
being agreed and acknowledged that no personal liability whatsoever shall attach
to, be imposed on or otherwise be incurred by any Non-Recourse Parties for any
obligation of the Guarantor or any of its successors or permitted assigns under
this Limited Guarantee or any documents or instrument delivered in connection
herewith or in respect of any oral representations made or alleged to have been
made in connection herewith or for any claim (whether at law or in equity or in
tort, contract or otherwise) based on, in respect of, or by reason of such
obligation or its creation. Except for any claims that are Non-Prohibited Claims
against such Person, recourse against the Guarantor under this Limited
Guarantee, subject to the limitations and conditions set forth herein, shall be
the sole and exclusive remedy of the Guaranteed Party and all of its Affiliates
against the Guarantor and any Non-Recourse Parties in respect of any liabilities
or obligations arising under, or in connection with, the Merger Agreement or in
connection with the failure of the Transactions to be consummated for any reason
or otherwise in connection with the transactions contemplated thereby or in
respect of any representations made or alleged to be made in connection
therewith, whether at law or in equity, in contract, in tort or otherwise.
Nothing set forth in this Limited Guarantee shall affect or be construed to
affect any liability of Parent to the Guaranteed Party or shall confer or give
or shall be construed to confer or give to any Person other than the Guaranteed
Party (including any Person acting in a representative capacity) any rights or
remedies against any Person other than the Guarantor as expressly set forth
herein. Notwithstanding anything to the contrary contained herein or in the
Guarantor’s Equity Commitment Letter, under no circumstance shall the Guaranteed
Party be permitted or entitled to receive both (a) a grant of specific
performance under the Guarantor’s Equity Commitment Letter or under the Merger
Agreement to cause the Closing or to cause Parent to enforce the Equity
Commitment Letter and (b) payment of the Parent Termination Fee.
