Corporation into or with any corporation nor the merger or consolidation of any other corporation
into or with the Corporation nor the sale, lease, exchange or other disposition (for cash, shares

such series, and to fix the designation, relative rights, preferences and limitations of the shares
of each such series. The authority of the Board of Directors with respect to each series shall
include, but not be limited to, determination of the following:

(3) whether the holders of shares of that series shall have voting rights in addition to the
voting rights provided by law and, if so, the terms and conditions of exercise of such voting
rights;

(4) whether shares of that series shall be convertible into or exchangeable for shares of any
other class, or any series of the same or any other class, and, if so, the terms and conditions
thereof, including the date or dates when such shares shall be convertible into or exchangeable for
shares of any other class, or any series of the same or any other class, the price or prices of or
the rate or rates at which shares of such series shall be so convertible or exchangeable, and any

and the relation to, the rights in respect thereto of any class or classes of stock or any other
series of the same class; and

(8) any other relative rights, preferences and limitations of that series;

provided, however, that if the stated dividends and amounts payable on liquidation with respect to
shares of any series of the Preferred Stock are not paid in full, the shares of all series of the
Preferred Stock shall share ratably in the payment of dividends including accumulations, if any, in
accordance with the sums which would be payable on such shares if all dividends were declared and
paid in full, and in any distribution of assets (other than by way of dividends) in accordance with

any of the shares of any class, and no holder of any of the shares of any series of any class, of
the Corporation shall be entitled as of right to subscribe for, purchase or otherwise acquire any
shares of any class, or shares of any series of any class, of the Corporation which the Corporation
proposes to issue or any rights or options which the Corporation proposes to grant for the purchase

the Corporation, whether now or hereafter authorized or created, may be issued, or may be reissued
or transferred if the same have been reacquired and have treasury status, and any and all of such
rights and options may be granted by the Board of Directors to such persons, firms, corporations
and associations, for such lawful consideration and on such terms as the Board of Directors in its
discretion may determine, without first offering the same, or any thereof, to any said holder.

SEVENTH: (a) The Corporation shall be permitted to indemnify, and advance expenses to, any
officer, director or other person to the fullest extent from time to time permitted by law, and, to
the extent consistent therewith shall indemnify or advance expenses to any such officer, director
or other person to the fullest extent required by or pursuant to any present or future by-law of
the Corporation, agreement approved by the Board of Directors, or resolution of shareholders or
directors; and the adoption of any such resolution or entering into of any such agreement approved
by the Board of Directors is hereby authorized.

(b) A director of the Corporation shall not be personally liable to the Corporation or its
shareholders for damages for any breach of duty as a director; provided that, except as hereinafter
provided, this Section SEVENTH shall neither eliminate nor limit liability: (a) if a judgment or
final adjudication adverse to the director establishes that (i) the director’s acts or omissions
were in bad faith or involved intentional misconduct or a knowing violation of law, (ii) the
director personally gained in fact a financial profit or other advantage to which the director was
not legally entitled, or (iii) the director’s acts violated Section 719 of the New York Business
Corporation Law; or (b) for any act or omission prior to the effectiveness of this Section SEVENTH.
If the Corporation hereafter may by law be permitted to further eliminate or limit the personal
liability of directors, then pursuant hereto the liability of a director of the Corporation shall,
at such time, automatically be further eliminated or limited to the fullest extent permitted by
law. Any repeal of or modification to the provisions of this Section SEVENTH shall not adversely
affect any right or protection of a director or the Corporation existing pursuant to this Section
SEVENTH immediately prior to such repeal or modification.

EIGHTH: (a) The Board of Directors of the Corporation shall consist of three (3) directors
subject to increase or decrease within the limits of not less than three (3) nor more than seven
(7) directors, the exact number of directors within the minimum and maximum limitations specified
herein to be determined from time to time by resolution of a majority of the entire Board of
Directors; provided, however, that the number of directors shall be increased beyond the foregoing
limit, to the extent required, in the event that (and for so long as) the holders of any Preferred
Stock of the Corporation, voting as a separate class or series under any provisions of the
Certificate of Incorporation, shall be entitled to elect any directors.

(b) No director of the Corporation shall be removed from office as a director except (i) for
cause by the vote of (A) the holders of at least a majority of the outstanding shares of capital
stock of the Corporation entitled to vote at an election of directors (considered for this purpose
as one class) or (B) a majority of the entire Board of Directors or (ii) without cause by the
majority vote of the holders of the outstanding shares of capital stock of the Corporation entitled
to vote at an election of directors (considered for this purpose as one class), provided that this
provision shall not apply to any directors elected by holders of any Preferred Stock voting as a
separate class or series under any provisions of the Certificate of Incorporation, which directors
may be removed only as provided in the provisions of the Certificate of Incorporation relating to
any such Preferred Stock.”

(6) The amendments to, and restatement of, the Certificate of Incorporation of the Corporation
herein provided for were authorized by the unanimous written consent of the Board of Directors of
the Corporation and by the affirmative vote of the holders of at least a majority of all
outstanding shares of the

the Corporation held December 11, 2008.

Exhibit 10(j)

TERMS OF QUALIFYING RESTRICTED STOCK UNIT (“QRSU”) GRANT

or

PERFORMANCE RESTRICTED STOCK UNIT (“PRSU”) GRANT*

PURSUANT TO THE

ILLINOIS TOOL WORKS 2006 STOCK INCENTIVE PLAN (THE “PLAN “)

	(a)	 	In the event of a stock dividend, stock split, reorganization or recapitalization,
appropriate adjustment will be made in the number of shares subject to the QRSU.
	 
	(b)	 	No portion of the QRSU will vest prior to three years from [Date of Grant]. On [End of Three
Years from Date of Grant], if the Compensation Committee certifies that the performance goal
set with respect to this QRSU has been met, 100% of the QRSUs will become vested. Upon
vesting, you will receive one share of Common Stock of the Company for each vested QRSU. Any
fractional vested QRSUs will be paid in cash based on the Fair Market Value of the Common
Stock on the distribution date.
	 
	(c)	 	You shall have no voting, dividend or subscription rights except with respect to the shares
which have been issued to you following the vesting of your QRSUs. Your rights under this QRSU
agreement may not be assigned or transferred other than as permitted by the Plan.
	 
	(d)	 	If prior to [End of Three Years from Date of Grant] you terminate employment with the Company
by reason of death or disability, as defined by the Company’s benefit plans, your QRSU shall
be fully vested, provided that the Compensation Committee certifies that the performance goal
set with respect to this QRSU has been met.
	 
	(e)	 	If you retire (defined as termination of employment with the Company after attaining age 62
and 10 years of service or age 65 with 5 years of service under the Company’s retirement plan)
prior to [End of Three Years from Date of Grant], and your QRSU was granted within a year
prior to your retirement, then 25% of your QRSU may become vested, and if your QRSU was
granted more than a year prior to your retirement, then 100% of your QRSU may become vested,
provided that the Compensation Committee certifies that the performance goal set with respect
to this QRSU has been met.
	 
	(f)	 	If you terminate your employment for any reason other than death, retirement or disability
prior to [End of Three Years from Date of Grant], you will forfeit your QRSUs.
	 
	(g)	 	Notwithstanding the foregoing, the Compensation Committee of the Board of Directors may, in
its sole discretion, deem this QRSU grant to be immediately forfeited if you are terminated
for cause (as defined by the Committee), compete with the Company, or conduct yourself in a
manner adversely affecting the Company.
	 
	(h)	 	Solely to the extent the QRSUs are considered deferred compensation within the meaning of
Code Section 409A, payments shall be subject to the requirements of Code Section
409A(a)(2)(B)(i). “Corporate Change” and “disability” shall be construed consistent with
applicable IRS regulations.
	 
	(i)	 	The QRSU is subject to the terms of the Plan. Any inconsistencies shall be resolved in favor of
the Plan.
	 
	(j)	 	These QRSUs and the Plan should be construed in accordance with and governed by the laws of
the State of Illinois, United States of America.

The vesting of this QRSU generally results in ordinary income being recognized for tax purposes in
an amount equal to the fair market value of the shares issued in payment of the QRSU as of the
vesting date.

*If the grant is called Performance Restricted Stock Unit, then “QRSU” would be replaced with
“PRSU” wherever it appears in this form of grant.
