<P STYLE="font: 10pt/120% Times New Roman, Times, Serif; margin: 5pt 0 0; text-indent: 0.5in">Section 145(a) of the Delaware General
Corporation Law (the &ldquo;DGCL&rdquo;) provides that a Delaware corporation may indemnify any person who was or is a party or
is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative
or investigative (other than an action by or in the right of the corporation) by reason of the fact that such person is or was
a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director,
officer, employee or agent of another corporation, partnership, joint venture, trust or enterprise, against expenses (including
attorneys&rsquo; fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection
with such action, suit or proceeding if he or she acted in good faith and in a manner he or she reasonably believed to be in or
not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had no reasonable
cause to believe his or her conduct was unlawful.</P>

<P STYLE="font: 10pt/120% Times New Roman, Times, Serif; margin: 5pt 0 0; text-indent: 0.5in">Section 145(b) of the DGCL provides
that a Delaware corporation may indemnify any person who was or is a party or is threatened to be made a party to any threatened,
pending or completed action or suit by or in the right of the corporation to procure a judgment in its favor by reason of the fact
that such person acted in any of the capacities set forth above, against expenses (including attorneys&rsquo; fees) actually and
reasonably incurred by such person in connection with the defense or settlement of such action or suit if he or she acted under
similar standards, except that no indemnification may be made in respect of any claim, issue or matter as to which such person
shall have been adjudged to be liable to the corporation unless and only to the extent that the court in which such action or suit
was brought shall determine that, despite the adjudication of liability but in view of all the circumstances of the case, such
person is fairly and reasonably entitled to be indemnified for such expenses which the court shall deem proper.</P>

<P STYLE="font: 10pt/120% Times New Roman, Times, Serif; margin: 5pt 0 0; text-indent: 0.5in">Section 145 of the DGCL further provides
that: (i) to the extent that a former or present director or officer of a corporation has been successful in the defense of any
action, suit or proceeding referred to in subsections (a) and (b) or in the defense of any claim, issue or matter therein, such
person shall be indemnified against expenses (including attorneys&rsquo; fees) actually and reasonably incurred by him or her in
connection therewith; (ii) indemnification provided for by Section 145 shall not be deemed exclusive of any other rights to which
the indemnified party may be entitled; and (iii) the corporation may purchase and maintain insurance on behalf of any present or
former director, officer, employee or agent of the corporation or any person who at the request of the corporation was serving
in such capacity for another entity against any liability asserted against such person and incurred by him or her in any such capacity
or arising out of his or her status as such, whether or not the corporation would have the power to indemnify him or her against
such liabilities under Section 145.</P>

<P STYLE="font: 10pt/120% Times New Roman, Times, Serif; margin: 5pt 0 0; text-indent: 0.5in">Section 102 of the DGCL allows a
Delaware corporation to eliminate or limit the personal liability of a director to the corporation or to any of its stockholders
for monetary damage for a breach of fiduciary duty as a director, except in the case where the director (i) breaches such director&rsquo;s
duty of loyalty to the corporation or its stockholders, (ii) fails to act in good faith, engages in intentional misconduct or knowingly
violates a law, (iii) authorizes the payment of a dividend or approves a stock purchase or redemption in violation of Section 174
of the DGCL or (iv) obtains an improper personal benefit. In accordance with the DGCL, Article VII of the Registrant&rsquo;s Restated
Certificate of Incorporation provides that, to the fullest extent permitted by the DGCL as it may be amended, no director shall
be personally liable to the Registrant or its stockholders for monetary damages for breach of fiduciary duty as a director.</P>

<P STYLE="font: 10pt/120% Times New Roman, Times, Serif; margin: 5pt 0 0; text-indent: 0.5in">As permitted by the DGCL, the Registrant&rsquo;s
Bylaws, as amended, provide that, under certain circumstances, the Registrant shall indemnify its directors and officers against
all expense, liability and loss, including attorneys&rsquo; fees, actually and reasonably incurred by such persons. The Registrant
has also entered into indemnification agreements with its officers and directors containing provisions which are in some respects
broader than the specific indemnification provisions contained in Delaware law and which require that, to the extent the Registrant
maintains liability insurance applicable to officers or directors, each officer and director shall be covered by such policies
to the same extent as are accorded the most favorably insured of the Registrant&rsquo;s officers or directors, as the case may
be.</P>

<P STYLE="font: 10pt/120% Times New Roman, Times, Serif; margin: 5pt 0 0; text-indent: 0.5in">The Registrant maintains insurance
covering its directors and officers against certain liabilities incurred by them in their capacities as such, including among other
things, certain liabilities under the Securities Act of 1933, as amended.</P>

In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question of whether such indemnification by it is against public policy as expressed in the Securities Act of 1933 and will be governed by the final adjudication of such issue.</TD></TR>

(1) 	Pursuant to Rule 416 of the Securities Act of 1933, as amended ("Securities Act"), this registration statement shall also cover any additional shares of the registrant's common stock that become issuable under the CEB Inc. 2012 Stock Incentive Plan (the "2012 Plan"), as described herein, by reason of any stock dividend, stock split, recapitalization or any other similar transaction effected without the registrant's receipt of consideration that results in an increase in the number of the registrant's outstanding shares of common stock.
(2)	Estimated in accordance with Rules 457(h)(1) and 457(c) under the Securities Act. The proposed maximum offering price per share of $108.98 was computed by averaging the high and low prices of a share of the Registrant's Common Stock as reported on the New York Stock Exchange on April 13, 2017.
(3)	Determined in accordance with Section 6(b) of the Securities Act at a rate equal to $115.90 per $1,000,000 of the proposed maximum aggregate offering price.
(4)	Pursuant to the Agreement and Plan of Merger and Reorganization, dated as of January 5, 2017 (the "Merger Agreement") by and among the Registrant, Cobra Acquisition Corp., a Delaware corporation and wholly-owned subsidiary of the Registrant, and CEB Inc., upon the closing of the transaction contemplated by the Merger Agreement on April 5, 2017 (the "Merger"), the Registrant assumed certain outstanding restricted share units under the 2012 Plan, and such restricted share units were automatically converted into restricted share units in respect of shares of the Registrant's common stock, subject to appropriate adjustments to the number of shares of each such award, resulting in restricted share units with respect to 593,835 shares of the Registrant's common stock assumed under the 2012 Plan.

Item 4.   Description of Securities.
Not applicable.
Item 5.   Interests of Named Experts and Counsel.
Not applicable.
Item 6.   Indemnification of Directors and Officers.
Section 145(a) of the Delaware General
Corporation Law (the "DGCL") provides that a Delaware corporation may indemnify any person who was or is a party or
is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative
or investigative (other than an action by or in the right of the corporation) by reason of the fact that such person is or was
a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director,
officer, employee or agent of another corporation, partnership, joint venture, trust or enterprise, against expenses (including
attorneys' fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection
with such action, suit or proceeding if he or she acted in good faith and in a manner he or she reasonably believed to be in or
not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had no reasonable
cause to believe his or her conduct was unlawful.
Section 145(b) of the DGCL provides
that a Delaware corporation may indemnify any person who was or is a party or is threatened to be made a party to any threatened,
pending or completed action or suit by or in the right of the corporation to procure a judgment in its favor by reason of the fact
that such person acted in any of the capacities set forth above, against expenses (including attorneys' fees) actually and
reasonably incurred by such person in connection with the defense or settlement of such action or suit if he or she acted under
similar standards, except that no indemnification may be made in respect of any claim, issue or matter as to which such person
shall have been adjudged to be liable to the corporation unless and only to the extent that the court in which such action or suit
was brought shall determine that, despite the adjudication of liability but in view of all the circumstances of the case, such
person is fairly and reasonably entitled to be indemnified for such expenses which the court shall deem proper.
Section 145 of the DGCL further provides
that: (i) to the extent that a former or present director or officer of a corporation has been successful in the defense of any
action, suit or proceeding referred to in subsections (a) and (b) or in the defense of any claim, issue or matter therein, such
person shall be indemnified against expenses (including attorneys' fees) actually and reasonably incurred by him or her in
connection therewith; (ii) indemnification provided for by Section 145 shall not be deemed exclusive of any other rights to which
the indemnified party may be entitled; and (iii) the corporation may purchase and maintain insurance on behalf of any present or
former director, officer, employee or agent of the corporation or any person who at the request of the corporation was serving
in such capacity for another entity against any liability asserted against such person and incurred by him or her in any such capacity
or arising out of his or her status as such, whether or not the corporation would have the power to indemnify him or her against
such liabilities under Section 145.
Section 102 of the DGCL allows a
Delaware corporation to eliminate or limit the personal liability of a director to the corporation or to any of its stockholders
for monetary damage for a breach of fiduciary duty as a director, except in the case where the director (i) breaches such director's
duty of loyalty to the corporation or its stockholders, (ii) fails to act in good faith, engages in intentional misconduct or knowingly
violates a law, (iii) authorizes the payment of a dividend or approves a stock purchase or redemption in violation of Section 174
of the DGCL or (iv) obtains an improper personal benefit. In accordance with the DGCL, Article VII of the Registrant's Restated
Certificate of Incorporation provides that, to the fullest extent permitted by the DGCL as it may be amended, no director shall
be personally liable to the Registrant or its stockholders for monetary damages for breach of fiduciary duty as a director.
As permitted by the DGCL, the Registrant's
Bylaws, as amended, provide that, under certain circumstances, the Registrant shall indemnify its directors and officers against
all expense, liability and loss, including attorneys' fees, actually and reasonably incurred by such persons. The Registrant
has also entered into indemnification agreements with its officers and directors containing provisions which are in some respects
broader than the specific indemnification provisions contained in Delaware law and which require that, to the extent the Registrant
maintains liability insurance applicable to officers or directors, each officer and director shall be covered by such policies
to the same extent as are accorded the most favorably insured of the Registrant's officers or directors, as the case may
be.
The Registrant maintains insurance
covering its directors and officers against certain liabilities incurred by them in their capacities as such, including among other
things, certain liabilities under the Securities Act of 1933, as amended.

Item 9.   Undertakings.
(a)
The undersigned registrant hereby undertakes:
(1)
To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:
(i) To include any prospectus required
by section 10(a)(3) of the Securities Act of 1933;
(ii) To reflect in the prospectus
any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment
thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration
statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of
securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum
offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate,
the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the "Calculation
of Registration Fee" table in the effective registration statement; and
(iii) To include any material
information with respect to the plan of distribution not previously disclosed in the registration statement or any material change
to such information in the registration statement; provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if
the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or
furnished to Commission by the registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are
incorporated by reference in the registration statement.
(2)
That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
(3)
To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.
(b)
The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant's annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
(c)
Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question of whether such indemnification by it is against public policy as expressed in the Securities Act of 1933 and will be governed by the final adjudication of such issue.
