AND OFFICERS</B></P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 12pt 0 0; text-align: justify; text-indent: 0.5in">Section 145 of the
General Corporation Law of Delaware (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 such corporation) by reason of the
fact that any such person is or was a director, officer, employee or agent of such 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 other
enterprise. The indemnity may include 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, provided that such officer
or director acted in good faith and in a manner such person 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. A Delaware corporation may indemnify officers and directors against expenses (including attorneys&rsquo; fees) in connection
with the defense or settlement of any action by or in the right of the corporation under the same conditions, except that no indemnification
is permitted without judicial approval if the officer or director is adjudged to be liable to the corporation. Where an officer
or director is successful on the merits or otherwise in the defense of an action referred to above, the corporation must indemnify
him or her against the expenses (including attorneys&rsquo; fees) that such officer or director actually and reasonably incurred.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 12pt 0 0; text-align: justify; 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 person&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)&nbsp;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 Times New Roman, Times, Serif; margin: 12pt 0 0; text-align: justify; 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 Times New Roman, Times, Serif; margin: 12pt 0 0; text-align: justify; 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>

</FONT>The undersigned Registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of
1933, each filing of the Registrant&rsquo;s annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange

the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new

</FONT>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 Securities and Exchange 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 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.</P>

Pursuant to Rule 416(a) of the Securities Act of 1933, as amended (the "Securities Act"),
        this Registration Statement shall also cover any additional shares of the Registrant's Common Stock that become issuable
        under the Gartner, Inc. 2014 Long-Term Incentive Plan (the "Plan") by reason of any stock dividend, stock split, recapitalization
        or other similar transaction effected without receipt of consideration that increases the number of the Registrant's outstanding
        shares of Common Stock.

Represents 2,185,980 shares of the Registrant's Common Stock reserved for issuance under
        the Plan as of May 29, 2014, the effective date of the Plan. In addition, 5,814,020 shares of common stock that were available
        for grant under the Amended and Restated 2003 Long-Term Incentive Plan (the "Prior Plan") as of May 29, 2014 have been
        added to the Plan's share reserve. The Registrant has previously registered, and paid the registration fee for, those shares
        reserved under the Prior Plan that now have been or will be included under this Registration Statement, on Form S-8 (Registration
        Nos. 333-160925, 333-127349 and 333-104753 filed on July 31, 2009, August 9, 2005 and April 25, 2003, respectively).

Estimated in accordance with Rules 457(h)(1) and 457(c) under the Securities Act of 1933, as

(4)
Amount of the registration fee was calculated pursuant to Section 6(b) of the Securities Act
        of 1933, as amended, and was determined by multiplying the Proposed Maximum Aggregate Offering Price by 0.0001162.

Not applicable.
ITEM 5.	     INTERESTS OF NAMED EXPERTS
AND COUNSEL
Not applicable.
ITEM 6.	     INDEMNIFICATION OF DIRECTORS
AND OFFICERS
Section 145 of the
General Corporation Law of Delaware (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 such corporation) by reason of the
fact that any such person is or was a director, officer, employee or agent of such 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 other
enterprise. The indemnity may include 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, provided that such officer
or director acted in good faith and in a manner such person 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. A Delaware corporation may indemnify officers and directors against expenses (including attorneys' fees) in connection
with the defense or settlement of any action by or in the right of the corporation under the same conditions, except that no indemnification
is permitted without judicial approval if the officer or director is adjudged to be liable to the corporation. Where an officer
or director is successful on the merits or otherwise in the defense of an action referred to above, the corporation must indemnify
him or her against the expenses (including attorneys' fees) that such officer or director actually and reasonably incurred.
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 person'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 percent change in the maximum
aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective registration statement;
(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 the 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 this 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
-
(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.
(h)
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 Securities and Exchange 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 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.
