Long-Term Cash Incentive Plan – Northern Trust Corp.

1.

Purpose. The purpose of the Plan is to promote the growth
and profitability of the Corporation and its Subsidiaries by encouraging
outstanding individuals to accept or continue employment with the Corporation
and its Subsidiaries through the provision of incentive compensation
opportunities in the form of Long Term Cash Incentive Awards (“Awards”).

2.

Administration.

(a)

The Committee shall administer the Plan, except as otherwise determined by
the Board. The Committee shall consist of at least two (2) Directors as the
Board may designate from time to time. Notwithstanding anything to the contrary
contained herein, membership of the Committee shall be limited to Board members
who meet the “non:employee director” definition in Rule 16b-3 under Section 16
of the Exchange Act.

(b)

The Committee shall have full power and authority to interpret the Plan, to
establish, amend and rescind any rules and regulations relating to the Plan, to
determine the terms and provisions of any Long Term Cash Incentive Award
Agreement entered into under the Plan, and to make all other determinations that
may be necessary or desirable for the administration of the Plan. Any
interpretation of the Plan by the Committee shall be final and binding on all
persons.

(c)

The Committee may delegate the administration of the Plan, in whole or in
part, on such terms and conditions as it may impose, to such other person or
persons as it may determine in its discretion, except with respect to Awards to
officers subject to Section 16 of the Exchange Act and except to the extent
prohibited by applicable law or the applicable rules of a stock exchange.

3.

Participants.

(a)

Participants shall consist of Employees whom the Committee may designate from
time to time to receive Awards under the Plan. Awards may be granted to
Participants who are or were previously Participants under this or other plans
of the Corporation or any Subsidiary, and the Corporation may continue to award
bonuses and other compensation to Participants under other programs now in
existence or hereafter established.

(b)

The Committee shall have the authority to amend the terms and conditions
relating to an Award, provided that no amendment shall adversely affect the
rights of any Participant under any outstanding Award in any material way

without the written consent of the Participant unless such amendment is
required by applicable law, or is necessary to cause the Award to be exempt
from, or comply with, Code Section 409A.

4.

Long Term Cash Incentive Awards. The Committee may in its
discretion award Long Term Cash Incentive Awards under the Plan to Participants
hereunder. Each Award shall be subject to such terms and conditions as the
Committee may determine at the time of grant, the general provisions of the
Plan, the terms and conditions of the applicable Long Term Cash Incentive Award
Agreement and the following specific rules:

(a)

Each Award shall be governed by a Long Term Cash Incentive Award Agreement
(“Award Agreement”), which shall specify such terms and conditions, not
inconsistent with the terms and conditions of the Plan, as the Committee shall
determine.

(b)

An Award shall consist of a commitment by the Corporation to distribute at
the time specified in, and in accordance with the terms of, the applicable Award
Agreement, an amount set forth in the Award Agreement (“Award Amount”),
increased for interest in accordance with paragraph (c), below. An Award may be
subject to a vesting schedule and such other conditions, restrictions or
contingencies, as determined by the Committee and described in the Award
Agreement.

(c)

The Corporation shall maintain an account (“Account”) on its books on behalf
of each Participant which shall reflect the Award Amount specified in the
Participant153s Award Notice, plus interest at a rate specified by the Committee
in the Award Agreement to be credited in accordance with the terms of such Award
Agreement. Interest specified in the Award Agreement shall in no event exceed
120 percent of the long-term applicable federal rate, as defined in Code Section
1274(d) for the month in which the Award is granted.

(d)

Distribution of any Award by the Company or its Subsidiaries shall be made on
the date or dates specified in the Award Agreement, subject to the provisions of
the Plan, including without limitation Section 8.

(e)

An Award will generally be satisfied by a distribution in cash to the
Participant, provided, however, that, at the discretion of the Committee, an
Award may be satisfied by payment of shares of Common Stock in lieu of cash, or
a combination of cash and shares of Common Stock. The number of shares of Common
Stock shall be equal to (i) the amount of the Award to be paid in stock in
accordance with this paragraph (e) divided by (ii) the Fair Market Value on the
date preceding the date of distribution of a share of Common Stock, provided
that the issuance of any shares of Common Stock in accordance with this
paragraph (e) shall be contingent on the availability of shares of Common Stock
under any shareholder-approved plan of the Corporation providing for the
issuance of Stock in satisfaction of the Awards hereunder (which in no event
shall be an employee stock purchase plan).

(f)

In the case of Awards under the Plan that are settled in shares of Common
Stock, such shares shall be distributed under a stock plan adopted by the
Corporation and approved by the shareholders thereof that provides for the
issuance of Common Stock in satisfaction of Awards hereunder (which in no event
shall be an employee stock purchase plan.) In the event of any conflict between
this document and such stock plan, the provisions of the stock plan shall
govern.

5.

Adjustment. In the event of any reorganization,
recapitalization, stock split, stock distribution, merger, consolidation,
split-up, spin-off, combination, subdivision, consolidation or exchange of
shares, any change in the capital structure of the Corporation or any similar
corporate transaction, the Committee or the Board shall make such adjustments as
are necessary and appropriate to preserve the benefits or intended benefits of
the Plan and Awards granted under the Plan.

6.

Nontransferability. Except as provided below, each Award
granted under the Plan to a Participant shall not be transferable by the
Participant other than by will or the laws of descent and distribution. In the
event of the death of a Participant during employment or prior to the
termination, expiration, cancellation or forfeiture of any Award held by the
Participant hereunder, each vested Award theretofore granted to the Participant
shall be exercisable or payable to the extent and to such persons as provided
in, and in accordance with the terms of, the applicable Award Agreement.

7.

Change in Control.

(a)

The Committee may, in its discretion, at the time an Award is made hereunder
or at any time prior to a Change in Control of the Corporation, provide for the
acceleration of any time periods relating to the realization of such Awards
(such as the vesting requirements) so that such Awards may be realized as of the
date of a Change in Control of the Corporation. The Committee may, in its
discretion, include such further provisions and limitations in the Award
Agreement as it may deem equitable and in the best interests of the Corporation.

(b)

A “Change in Control” shall be deemed to have occurred if:

(i)

any Person is or becomes the Beneficial Owner, directly or indirectly, of
securities of the Corporation (not including in the securities beneficially
owned by such Person any securities acquired directly from the Corporation or
its Affiliates) representing 20% or more of the combined voting power of the
Corporation153s then outstanding securities, excluding any Person who becomes such
a Beneficial Owner in connection with a transaction described in clause (A) of
clause (iii) below; or

(ii)

the election to the Board of Directors of the Corporation, without the
recommendation or approval of two-thirds of the incumbent Board of Directors of
the Corporation, of the lesser of: (A) three directors; or (B) directors
constituting a majority of the number of directors of the Corporation then in
office, provided, however, that directors whose initial assumption of office is
in connection with an actual or threatened election contest, including but not
limited to a consent solicitation, relating to the election of directors of the
Corporation will not be considered as incumbent members of the Board of
Directors of the Corporation for purposes of this section; or

(iii)

there is consummated a merger or consolidation of the Corporation or any
direct or indirect subsidiary of the Corporation with any other company, other
than (A) a merger or consolidation which would result in the voting securities
of the Corporation outstanding immediately prior to such merger or consolidation
continuing to represent (either by remaining outstanding or by being converted
into voting securities of the surviving entity or any parent thereof), at least
60% of the combined voting power of the securities of the Corporation or such
surviving entity or any parent thereof outstanding immediately after such merger
or consolidation, or (B) a merger or consolidation effected to implement a
recapitalization of the Corporation (or similar transaction) in which no Person
is or becomes the Beneficial Owner, directly or indirectly, of securities of the
Corporation (not including in the securities Beneficially Owned by such Person
any securities acquired directly from the Corporation or its Affiliates)
representing 20% or more of the combined voting power of the Corporation153s then
outstanding securities; or

(iv)

the stockholders of the Corporation approve a plan of complete liquidation or
dissolution of the Corporation or there is consummated an agreement for the sale
or disposition by the Corporation of all or substantially all of the
Corporation153s assets, other than a sale or disposition by the Corporation of all
or substantially all of the Corporation153s assets to an entity, at least 60% of
the combined voting power of the voting securities of which are owned by
stockholders of the Corporation in substantially the same proportions as their
ownership of the Corporation immediately prior to such sale.

8.

Other Provisions.

(a)

Any Award under the Plan shall be subject to such other provisions as the
Committee determines, including, provisions permitting the lapse of restrictions
in the event of death, disability or retirement, understandings or conditions as
to the Participant153s employment in addition to those specifically provided for
under the Plan, provisions for the forfeiture of Awards and/or the recoupment of
all amounts received in connection with an award in the event of breach of
noncompetition, nonsolicitation, or confidentiality agreements, restatement of
the financial statements of the Corporation or Subsidiary or Business Unit
thereof, misconduct, or the occurrence of risk based events or conditions
identified by the Committee, or such other conduct or events as the Committee
shall specify, during or following termination of employment, and provisions
permitting the deferral of the receipt of Awards for such period and upon such
terms and conditions as the Committee shall determine.

(b)

Notwithstanding anything herein or in any Award Agreement to the contrary,
provisions permitting the deferral of the receipt of Awards must satisfy the
requirements of Code Section 409A and applicable regulations and guidance
promulgated thereunder, including without limitation all deadlines for deferral
elections, so as to avoid the income tax, interest and penalty provisions of
Section 409A.

(c)

An Award that is subject to Code Section 409A shall not be distributable on
account of retirement or termination of employment, unless the individual incurs
a Separation from Service.

(d)

An Award that would otherwise be distributed to a Participant in a given
calendar year may be delayed, in the Committee153s discretion, to the extent that
the Committee reasonably anticipates that if the payment were made as scheduled
the Corporation153s deduction with respect to such payment would not be permitted
due to the application of Code Section 162(m). Awards not paid as a result of
the above limitation shall be paid in the earlier of (i) the Corporation153s first
taxable year in which the Committee reasonably anticipates that if the payment
is made during such year the deduction of such payment will not be barred by
application of Section 162(m), or (ii) the period beginning with the date of the
Participant153s Separation from Service and ending on the later of the last day of
the taxable year of the Corporation in which the Participant incurs a Separation
from Service or the 15^th day of the third month following the
Participant153s Separation from Service.

(e) (i)

Anything in the Plan to the contrary notwithstanding, including without
limitation Section 8(d), if as of the date a Participant incurs a Separation
from Service, the Participant is a Key Employee, any distribution of an Award
that is subject to the provisions of Code Section 409A to such Participant due
to such Separation from Service that would otherwise be made during the six
months following such Separation from Service shall be made on the date that is
six months and one day following such Separation from Service.

(ii)

“Key Employee” means a Participant who is a “specified employee” within the
meaning of Code Section 409A(a)(2)(B)(i). The Corporation153s Key Employees shall
be identified annually pursuant to Section 8(e)(iii).

(iii)

The Specified Employee Identification Date as defined in Treas. Reg.
§1.409A-1(i)(3), to be used in determining Key Employees of the Corporation
shall be September 30 of any calendar year. The January 1 of the calendar year
next following that calendar year shall be the Specified Employee Effective
Date, as defined in Treas. Reg. §1.409A-1(i)(4), for Participants identified as
Key Employees on the immediately preceding Specified Employee Identification
Date. Participants identified as Key Employees on a Specified Employee
Identification

Date (September 30) shall be treated as Key Employees under the Plan for the
12-month period beginning on the Specified Employee Effective Date (January 1)
next following such Specified Employee Identification Date.

9.

Taxes. The Corporation shall have the right to deduct from
any payment to be made under the Plan the amount of any taxes required by law to
be withheld from such payment, or to require a Participant to pay to the
Corporation such amount required to be withheld prior to the issuance or
delivery of any shares of Common Stock or the payment of any cash in connection
with any Award under the Plan. The Committee may, in its discretion and subject
to such rules as it may adopt, permit a Participant to elect to satisfy such
withholding obligations through cash payment by the Participant, or through the
surrender of shares of Common Stock which the Participant is otherwise entitled
to receive under the Plan.

10.

Amendment, Suspension or Termination of Plan. The Board may
at any time amend, suspend or terminate the Plan as it deems advisable and in
the best interests of the Corporation; provided, that no amendment, suspension
or termination shall adversely affect the right of any Participant under any
outstanding Award in any material way without the written consent of the
Participant, unless such amendment, suspension or termination is required by
applicable law. No amendment of the Plan shall be made without stockholder
approval if stockholder approval is required by law, regulation or stock
exchange rule. Anything in this Section 10 or elsewhere in the Plan to the
contrary notwithstanding:

(a)

the Plan may be amended in any manner necessary to ensure that the Plan
complies in all applicable respects with Code Section 409A; and

(b)

the Plan may not be amended in any manner that would cause the Plan to fail
to comply in any applicable respect with Code Section 409A.

11.

No Contract of Employment. Neither the adoption of the Plan
nor the grant of any Award under the Plan shall be deemed to obligate the
Corporation or any Subsidiary to continue the employment of any Participant for
any particular period, nor shall the granting of an Award constitute a request
or consent to postpone the retirement date of any Participant.

12.

Applicable Law. All questions pertaining to the validity,
construction and administration of the Plan and any Award Agreement, and all
claims or causes of action arising under, relating to, or in connection with,
the Plan or any Award granted under the Plan shall be determined in conformity
with the laws of the State of Delaware, without regard to the conflict of law
provisions of any state.

of the Code and all persons with whom the Corporation would be considered a
single employer under Code Section 414(c) substituting 50% for the 80% standard

to him as an Employee, his services as a Director shall be disregarded.

(p)

“Subsidiary” shall mean any entity that is directly or indirectly controlled
by the Corporation or any entity in which the Corporation has a significant
equity or other interest, as determined by the Committee in its discretion.

Code Section 409A, and the Plan shall be construed and administered so as to
cause such Awards to be exempt from or comply with that Code section,
respectively, as applicable.
