3. ESTABLISHMENT OF TARGET AWARD, PERFORMANCE CRITERIA, TARGETS AND PERFORMANCE
SCALE.

(a) In General. The Committee shall designate the Participants eligible to
receive an Award for an Award Period. The Committee shall establish the
following for each Participant (or group of Participants) for an Award Period:

(i) A Target Award;

(ii) The applicable Performance Criteria or Criterion;

(iii) The Performance Target with respect to each Performance Criterion that
will result in payment of 100% of the portion of the Target Award assigned to
such Criterion; and

(iv) The Performance Scale, in the form of schedule or matrix, which shall set
forth (A) the percentage of the Target Award payable with respect to a
Performance Criterion if achievement is higher or lower than the Performance
Target, and (B) the weighting of Performance Criteria if more than one is
selected with respect to a Participant (or a group of Participants).

(b) Time of Establishment. The Committee shall determine the Target Award,
Performance Criteria, Performance Target, Award Period and Performance Scale for
each Participant (or group of Participants) not later than 90 days after the
beginning of the Award Period to which such measures relate; provided, however,
that the outcome is substantially uncertain at the time the measure is
established and that no such determination shall be made after 25 percent of the
Award Period has elapsed.

(c) Non-uniform Determinations. The Committee’s determinations under the Plan
need not be uniform and may be made by it selectively among Participants and
from Award Period to Award Period.

4. AWARDS

(a) Award Determination. At the end of an Award Period, the Committee shall
determine and certify in writing:

(i) The extent to which Performance Targets established for the Participant (or
a group of Participants) have been achieved with respect to such Award Period;
and

(ii) The percentage of the Target Award or factor from the Performance Scale
applicable to each Participant (or group of Participants) based on achievement
during such Award Period.

The Award payable to a Participant with respect to an Award Period shall be the
percentage of Target Award determined under (ii), or, in the event a factor is
determined under (ii), the amount determined by multiplying the Participant’s
Target Award by such factor, such percentage of Target Award or amount subject
to adjustment by the Committee pursuant to subsection (b), the limit on Awards
set forth in subsection (c), and the employment requirement set forth in
subsection (d).

(b) Committee Overrides. With respect to a Target Award established by the Chief
Executive Officer, the Chief Executive Officer may increase the amount of the
Award determined under subsection (a) if he believes such action would be in the
best interest of the Corporation. With respect to a Target Award established by
the Compensation Committee, the Committee may not increase the amount of the
Award determined under subsection (a). With respect to a Target Award
established for any Participant, the Committee may reduce the amount of the
Award determined under subsection (a) if it (or he) believes such action would
be in the best interest of the Corporation.

(c) Maximum Award. Notwithstanding any provision of this Plan to the contrary,
the maximum Award payable to any Participant with respect to any Award Period is
$3,000,000.

(d) Employment Requirement. No Award shall be payable to a Participant who is
not an Employee on the date the Award is scheduled to be paid; provided,
however, that a Participant who ceases to be an Employee for any of the
following reasons after at least one-half of the Award Period has elapsed shall
receive a pro-rata portion of the award that would have been paid to him had he
been an Employee on the date the Award is scheduled to be paid: death,
disability (as determined by the Committee) or retirement on or after the Early
Retirement Date or Normal Retirement Date (as such terms are defined in Part A
of the Thomas & Betts Pension Plan as in effect on February 1, 2008). Such
proration shall be based on the Participant’s active service during the Award
Period.

(e) Payment of Awards. Any Award payable under this Section 4 shall be paid in
cash within the 21/2 month period immediately following the last day of the
Award Period; provided, however, that (i) such period shall be less than 21/2
months to the extent necessary to cause such period to begin and end in the same
calendar year, (ii) the Participant shall have no discretion over the date his
or her payment is made, and (iii) no interest shall be payable to reflect a
payment date after the end of the Award Period.

5. ADMINISTRATION

(a) Committee. The Plan and all Awards shall be administered by the Committee
which shall be:

(i) With respect to a Target Award for an Employee who is a Covered Employee on
the date the Target Award is established, the Committee shall be the
Compensation Committee of the Board with respect to all determinations relating
to such Target Award; or

(ii) With respect to a Target Award for an Employee who is not a Covered
Employee on the date the Target Award is established, the Committee shall be the
Chief Executive Officer of the Corporation with respect to all determinations
relating to such Target Award.

(b) Authority. The Committee shall have full and complete authority, in its sole
and absolute discretion, (i) to exercise all of the powers granted to it under
the Plan, (ii) to construe, interpret and implement the Plan and any related
document, (iii) to prescribe, amend and rescind rules relating to the Plan,
(iv) to make all determinations necessary or advisable in administering the
Plan, and (v) to correct any defect, supply any omission and reconcile any
inconsistency in the Plan.

The Committee may delegate to one or more Employees the authority to execute and
deliver such instruments and documents, to do all such acts and things, and to
take all such other steps deemed necessary, advisable or convenient for the
effective administration of the Plan in accordance with its terms and purpose,
except that the Committee may not delegate any authority for which the action of
a committee of outside directors is required under Code §162(m) or would be
required if the Employee were a Covered Employee (e.g., decisions regarding
timing, eligibility, amount or other material terms of any Awards).

(c) Determinations. The actions and determinations of the Committee on all
matters relating to the Plan and any Awards will be final and conclusive.

(d) Liability. No member of the Committee or the Board will be liable for any
action taken or determination made in good faith with respect to the Plan or any
Award thereunder, and the Corporation will defend Committee and Board members
for any actions taken or decisions made in good faith under the Plan.

(e) Code §162(m). It is the intent of the Corporation that this Plan and Target
Awards hereunder (and Awards payable pursuant thereto) with respect to Covered
Employees satisfy, and be interpreted in a manner that satisfies, the applicable
requirements of Code §162(m) so that the Corporation’s tax deduction for
remuneration in respect of this Plan for services performed by Covered Employees
is not disallowed in whole or in part by the operation of Code §162(m). If any
provision of this Plan or if any Award would otherwise frustrate or conflict
with the intent expressed in this subsection, that provision shall be
interpreted and deemed amended so as to avoid such conflict. To the extent of
any remaining irreconcilable conflict with such intent, such provision shall be
deemed void as applicable to Covered Employees.

6. MISCELLANEOUS

(a) Nonassignability. No Target Award or Award will be assignable or
transferable (including pursuant to a pledge or security interest) other than by
will or by the laws of descent and distribution.

(b) Withholding Taxes. All payments under the Plan shall be subject to any
applicable governmental withholding tax requirements related thereto.

(c) Amendment or Termination of the Plan. The Board may, at any time and for any
reason, suspend or discontinue the Plan or revise, amend or terminate the Plan;
provided, however, that without the approval of stockholders (in the manner
described in regulations under Code §162(m)), the Board may not change (i) the
Performance Criteria, (ii) the individuals or class of individuals eligible to
participate in the Plan, or (iii) the maximum amount payable with respect to any
Award Period to any Participant under the Plan. Continuation of the Plan shall
be subject to stockholder approval to the extent required by regulations under
Code §162(m) (e.g., no later than the first stockholder meeting that occurs in
the fifth year following the year in which stockholders previously approved the
material terms of the performance goal).

(d) Other Payments or Awards. Nothing contained in the Plan will be deemed in
any way to limit or restrict the Corporation, any Subsidiary, or the Committee
from making any award or payment to any person under any other plan, arrangement
or understanding, whether now existing or hereafter in effect.

(e) Payments to Other Persons. If payments are legally required to be made to
any person other than the person to whom any amount is available under the Plan,
payments will be made to the person whom the Committee, or its delegate,
believes to be legally entitled to the payment. Any such payment will be a
complete discharge of the liability under the Plan.

(f) Unfunded Plan. No provision of the Plan will require the Corporation or any
Subsidiary, for the purpose of satisfying any obligations under the Plan, to
purchase assets or place any assets in a trust or other entity to which
contributions are made or otherwise to segregate any assets; nor will the
Corporation or any Subsidiary maintain separate bank accounts, books, records or
other evidence of the existence of a segregated or separately maintained or
administered fund for such purposes. Participants shall have no rights under the
Plan other than as unsecured general creditors of the Corporation and its
Subsidiaries, except that insofar as they may have become entitled to payment of
additional compensation by performance of services, they will have the same
rights as other employees under generally applicable law.

(g) Limits of Liability. Neither the Corporation or a Subsidiary, nor any member
of the Board, the Committee, or any other person participating in the
interpretation, administration or application of the Plan shall have any
liability to any party for any action taken, or not taken, in good faith under
the Plan.

(h) Rights of Employees. Nothing contained in this Plan will confer upon any
Employee or Participant any right to continue in the employ or other service of
the Corporation or a Subsidiary, or constitute any contract or limit in any way
the right of the Corporation or a Subsidiary to change such person’s
compensation or other benefits, or to terminate the employment or other service
of such person with or without cause.

(i) Section Headings. The section headings contained herein are for convenience
only, and in the event of any conflict, the text of the Plan, rather than the
section headings, will control.

(j) Invalidity. If any term or provision contained herein will to any extent be
invalid or unenforceable, such invalidity or unenforceability will not affect
any other provision or part hereof.

(k) Applicable Law. The Plan will be governed by the laws of the jurisdiction in
which the Corporation is incorporated as determined without regard to the
conflict of law principles thereof.

(l) Successors. The Plan shall be binding on the Corporation and its successors,
including any corporate or other business entity which shall, whether by merger,
consolidation, purchase or otherwise, acquire all or substantially all of the
business and assets of the Corporation.

(m) Effective Date. This amended and restated Plan shall be effective as of
January 1, 2009, and as amended from time to time thereafter; provided, however,
that if this amended and restated Plan is not approved by stockholders, in the
manner described in regulations under Code §162(m), no Award shall be paid to
any Covered Employee pursuant to this amended and restated Plan. This amended
and restated Plan shall apply to Target Awards determined by the Committee on or
after January 1, 2009 and Awards payable pursuant to such Target Awards. This
amended and restated Plan shall not apply to Target Awards determined by the
Committee before January 1, 2009 or Awards payable pursuant to such Target
Awards.
