ORBITAL ATK, INC. DEFINED BENEFIT
SUPPLEMENTAL EXECUTIVE RETIREMENT PLAN
As Amended and Restated January 1, 2016
SECTION 1

INTRODUCTION
1.1.    Purposes of Plan. The purposes of the Orbital ATK, Inc. Defined Benefit
Supplemental Executive Retirement Plan (formerly known as the "Alliant
Techsystems Inc. Defined Benefit Supplemental Executive Retirement Plan") are:
(1) to restore the benefit amounts that would be payable to select participants
in certain tax‑qualified defined benefit pension plans sponsored by Orbital ATK,
Inc. (“Orbital ATK”) as described in Section 3.2 hereof (the “Pension Plans”)
absent the limitations in sections 401(a)(17) and 415 of the Internal Revenue
Code of 1986, as amended (the “Code”), and absent a participant’s election to
voluntarily defer compensation, (2) to pay frozen benefits under certain frozen
plans as described in Appendix B, Appendix C and Appendix D, and (3) in certain
cases, to provide additional benefits pursuant to employment agreements or other
similar agreements between Orbital ATK and employees who are members of a select
group of management or highly compensated employees as described in Appendices E
and F.
1.2.    History. Orbital ATK has heretofore adopted tax‑qualified defined
benefit Pension Plans called: “ORBITAL ATK, INC. PENSION AND RETIREMENT PLAN,”
and the “THIOKOL PROPULSION PENSION PLAN” (the “Pension Plans”) for the purpose
of providing retirement benefits to certain of its employees and employees of
certain affiliates. The Pension Plans are subject to the Employee Retirement
Income Security Act of 1974, as amended, (“ERISA”), and are intended to qualify
under section 401(a) of the Code. By operation of section 401(a) of the Code,
benefits under the Pension Plans are restricted so that they do not exceed
maximum benefits allowed under section 415 of the Code. In addition, the maximum
amount of annual compensation which may be taken into account for any plan
participant may not exceed a fixed dollar amount which is established under
section 401(a)(17) of the Code.
In 1990, Alliant Techsystems Inc. ("Alliant"), the predecessor of Orbital ATK,
was spun‑off from Honeywell Inc. and, in connection therewith, established the
Alliant Techsystems Inc. Retirement Plan as a “spin‑off” from the Honeywell Inc.
Retirement Benefit Plan. Effective September 28, 1990, for the purpose of paying
the benefits Participating Employees would have been entitled to if Code section
415 and Code section 401(a)(17) limitations were not in effect and, also, to pay
certain employees transferred from Honeywell Inc. benefits already accrued under
the nonqualified plans sponsored by Honeywell Inc., Alliant adopted a plan known
as the “ALLIANT TECHSYSTEMS INC. SUPPLEMENTARY RETIREMENT PLAN (SRP)” by
adoption of a document entitled the “Honeywell Supplementary Retirement Plan
(SRP),” and a plan known as the “ALLIANT TECHSYSTEMS INC. SUPPLEMENTARY
EXECUTIVE RETIREMENT PLAN FOR COMPENSATION IN EXCESS OF $200,000 ($200K SERP)”
by adoption of a document entitled the “Honeywell Supplementary Executive
Retirement Plan for Compensation in Excess of $200,000 ($200K SERP) (Amended
through April 17, 1990).” In addition, Alliant adopted a plan

--------------------------------------------------------------------------------

known as the “ALLIANT TECHSYSTEMS INC. SUPPLEMENTARY EXECUTIVE RETIREMENT PLAN
FOR CECP PARTICIPANTS” by adoption of a document entitled the “Honeywell
Supplementary Executive Retirement Plan for CECP Participants (Amended Through
April 17, 1990)” as a frozen plan with benefits only for certain employees
acquired from Honeywell Inc. who were participants in the Plan while employed by
Honeywell Inc. Alliant also adopted a plan known as the “ALLIANT TECHSYSTEMS
INC. SUPPLEMENTARY EXECUTIVE RETIREMENT PLAN FOR BENEFITS IN EXCESS OF LIMITS
UNDER TAX REFORM ACT OF 1986” by adoption of a document entitled the “Honeywell
Supplementary Executive Retirement Plan for Benefits in Excess of Limits under
Tax Reform Act of 1986” as a frozen plan with benefits only for certain
employees acquired from Honeywell Inc. who were participants in the Plan while
employed by Honeywell Inc.
Pursuant to the subsequent acquisition of certain assets, employees and pension
plan assets and obligations from Hercules Incorporated (the “Hercules
Acquisition”), effective March 15, 1995, Alliant adopted a plan known as the
“ALLIANT TECHSYSTEMS INC. AEROSPACE PENSION RESTORATION PLAN” by adoption of the
portion of a document entitled the “Hercules Employee Pension Restoration Plan
Effective October 1, 1990” that provides benefits based on the Hercules
Incorporated Retirement Income Plan and its successor plans, including the
Hercules Incorporated Retirement Income Plan (Government‑Owned,
Corporation‑Operated) and the Hercules Incorporated Pension Plan.
Alliant also adopted, pursuant to the Hercules Acquisition, the ALLIANT
TECHSYSTEMS INC. DEFERRED COMPENSATION PLAN (a plan which is memorialized in a
document entitled the “Hercules Deferred Compensation Plan”) as a frozen plan
with frozen benefits for certain employees acquired from Hercules Incorporated.
Effective September 1, 1999, Alliant adopted a nonqualified deferred
compensation plan known as the “ALLIANT TECHSYSTEMS INC. MANAGEMENT DEFERRED
COMPENSATION PLAN” which provides that certain employees can voluntarily defer
compensation pursuant to a prior irrevocable agreement. Effective as of January
1, 2003, Alliant amended and restated its nonqualified deferred compensation
plan by the adoption of a document entitled “ALLIANT TECHSYSTEMS INC.
NONQUALIFIED DEFERRED COMPENSATION PLAN.”
Pursuant to the acquisition of certain assets, employees and pension plan assets
and obligations from Alcoa, Inc. (the “Thiokol Acquisition”), Alliant adopted a
plan known as the THIOKOL CORPORATION EXCESS PENSION PLAN (a plan which is
memorialized in a document entitled “Thiokol Corporation Excess Pension Plan
(Restated Effective October 1, 1990)”) that provides benefits based on the
Thiokol Propulsion Pension Plan for certain Thiokol Propulsion employees
acquired from Alcoa, Inc. The Thiokol Corporation Excess Pension Plan was merged
with and into this Alliant Techsystems Inc. Supplemental Executive Pension Plan
effective January 1, 2003.
Alliant also adopted, pursuant to the Thiokol Acquisition, the CORDANT
TECHNOLOGIES INC. SUPPLEMENTAL EXECUTIVE RETIREMENT PLAN (a plan which is
memorialized in a document entitled “CORDANT TECHNOLOGIES INC. SUPPLEMENTAL
EXECUTIVE RETIREMENT PLAN Amended and Restated Effective July 22, 1999”), as a
frozen plan with frozen benefits for certain employees acquired from Alcoa, Inc.
The Cordant Technologies Inc.

‑2‑

--------------------------------------------------------------------------------

Supplemental Executive Retirement Plan was merged with and into the Alliant
Techsystems Inc. Supplemental Executive Pension Plan effective January 1, 2003.
1.3.    Adoption of Plan. Effective January 1, 2003, Alliant adopted a document
entitled “ALLIANT TECHSYSTEMS INC. SUPPLEMENTAL EXECUTIVE RETIREMENT PLAN” as a
complete amendment and restatement of the Alliant Techsystems Inc. Supplementary
Retirement Plan, the Alliant Techsystems Inc. Supplementary Executive Retirement
Plan for Compensation in Excess of $200,000, the Alliant Techsystems Inc.
Supplementary Executive Retirement Plan for CECP Participants, the Alliant
Techsystems Inc. Supplementary Executive Retirement Plan for Benefits in Excess
of Limits under Tax Reform Act of 1986, the Alliant Techsystems Inc. Aerospace
Pension Restoration Plan, the Alliant Techsystems Inc. Deferred Compensation
Plan, the Thiokol Corporation Excess Pension Plan and the Cordant Technologies
Inc. Supplemental Executive Retirement Plan for employees who retire, die or
otherwise terminate employment on or after January 1, 2003.
The Alliant Techsystems Inc. Supplementary Executive Retirement Plan for CECP
Participants is attached as Appendix A and incorporated herein for purposes of
paying the benefits due thereunder, effective January 1, 2003. It applies only
to those Participating Employees who were participants in the Honeywell Inc.
CECP Plan and who are entitled to a “grandfathered” benefit under the Alliant
Techsystems Inc. Retirement Plan.
The Alliant Techsystems Inc. Supplementary Executive Retirement Plan for
Benefits in Excess of Limits under Tax Reform Act of 1986 is attached as
Appendix B and incorporated herein for purposes of paying the benefits due
thereunder, effective January 1, 2003. It applies only to those Participating
Employees who were participants in such plan and who are entitled to a
“grandfathered” benefit under Alliant Techsystems Inc. Retirement Plan.
The Alliant Techsystems Inc. Deferred Compensation Plan is attached as Appendix
C and incorporated herein for purposes of paying frozen benefits for certain
employees acquired from Hercules Incorporated.
The Cordant Technologies Supplemental Executive Retirement Plan is attached as
Appendix D and incorporated herein for purposes of paying any benefit
obligations acquired under that plan, which will be paid hereunder.
This Plan was amended and restated effective January 1, 2005 to comply with
section 409A of the Code, to add certain benefits/distribution options for
persons in Schedules 1 and 2, and to provide certain additional benefits as
described in Appendix F.
This Plan was amended and restated effective July 1, 2013 to rename it the
"ALLIANT TECHSYSTEMS INC. DEFINED BENEFIT SUPPLEMENTAL EXECUTIVE RETIREMENT
PLAN" and to reflect certain changes to the Pension Plans.
This Plan was amended and restated effective February 2, 2015 to take into
account the spinoff of Vista Outdoor Inc.

‑3‑

--------------------------------------------------------------------------------

This Plan is amended and restated effective January 1, 2016 to reflect the
merger of Alliant with Orbital Sciences Corporation, effective February 9, 2015.
SECTION 2

PLAN NAME
This plan shall be referred to as the ORBITAL ATK, INC. DEFINED BENEFIT
SUPPLEMENTAL EXECUTIVE RETIREMENT PLAN (the “Plan”).
SECTION 3

PARTICIPATING EMPLOYEES
3.1.    Participating Employees. The individuals eligible to participate in and
receive benefits under the Plan (“Participating Employees”) are those employees
of Orbital ATK, Inc. and its affiliates:
(a)
who are participants in the Alliant Techsystems, Inc. Nonqualified Deferred
Compensation Plan or any other nonqualified deferred compensation plan
maintained by Orbital ATK and its affiliates; or

(b)
whose individual employment agreement or other separate written agreement
between Orbital ATK (or an affiliate of Orbital ATK) and such employee specifies
that such employee is eligible to receive benefits under this Plan; or

(c)
who are Participants in one of the Pension Plans (as described in Section 3.2
below) and (i) who are actively employed by Orbital ATK, Inc. or its affiliates
or on approved leave of absence, and (ii) whose benefits under the applicable
Pension Plan would be greater if computed without regard to the limits imposed
under Code sections 401(a)(17) and 415; or

(d)
who are affirmatively selected for participation in this Plan by the Chief
Executive Officer (“CEO”) of Orbital ATK (or any person authorized to act on
behalf of the CEO by the Board of Directors of Alliant Techsystems Inc. (the
“Board of Directors”) and, for a Section 16 Officer, by the Compensation and
Human Resources Committee of the Board of Directors).

For purposes of this Plan, a Section 16 Officer is an officer of Orbital ATK (or
an affiliate of Orbital ATK) who is subject to the provisions of Section 16 of
the Securities Exchange Act of 1934, as amended. Notwithstanding anything
apparently to the contrary contained in this Plan, the Plan shall be construed
and administered to prevent the duplication of benefits provided under this Plan
and

‑4‑

--------------------------------------------------------------------------------

any other qualified or nonqualified plan maintained in whole or in part by
Orbital ATK or any predecessor, successor or affiliate.
Notwithstanding anything apparently to the contrary contained in this Plan, no
individual hired or rehired as an employee of Orbital ATK, its precedessor, or
any of its affiliates on or after January 1, 2007 shall be a Participating
Employee with respect to any period of employment beginning on or after January
1, 2007, except as and in accordance with such terms as may be specified by the
Personnel and Compensation Committee of the Board of Directors of Orbital ATK.
3.2.    Applicable Pension Plans. For purposes of this Plan, the “Pension Plans”
are:
(a)
Orbital ATK, Inc. Pension and Retirement Plan, including the benefit structures
under such plan known as the Alliant Techsystems Inc. Retirement Formula, the
Alliant Techsystems Inc. Aerospace Pension Formula, the ATK SEG Retirement
Formula, the Federal Cartridge Company Pension Formula, the ATK Pension Equity
Formula, the Alliant Lake City Retirement Formula, the Alliant Techsystems Inc.
Retirement Income Formula (GOCO), and the ATK Cash Balance Formula; and

(b)
Thiokol Propulsion Pension Plan, including the benefit structures known as the
Former Thiokol Propulsion Pension Plan Formula, the Thiokol Pension Equity
Formula, and the Thiokol Cash Balance Formula.

3.3.    Overriding Exclusion. Notwithstanding anything apparently to the
contrary in this Plan or in any written communication, summary, resolution or
document or oral communication, no individual shall be a Participating Employee
in this Plan, develop benefits under this Plan or be entitled to receive
benefits under this Plan (either for the employee or his or her survivors)
unless such individual is a member of a select group of management or highly
compensated employees (as that expression is used in ERISA). If a court of
competent jurisdiction, any representative of the U.S. Department of Labor or
any other governmental, regulatory or similar body makes any direct or indirect,
formal or informal, determination that an individual is not a member of a select
group of management or highly compensated employees (as that expression is used
in ERISA), such individual shall not be (and shall not have ever been) a
Participating Employee in this Plan at any time. If any person not so defined
has been erroneously treated as a Participating Employee in this Plan, upon
discovery of such error such person’s erroneous participation shall immediately
terminate ab initio and upon demand such person shall be obligated to reimburse
Alliant for all amounts erroneously paid to him or her.

--------------------------------------------------------------------------------

SECTION 4

BENEFITS PAYABLE
4.1.    Benefit for Participating Employees
4.1.1.    Amount of Benefit. This Plan shall pay to Participating Employees the
excess, if any, of
(a)
the amount that would have been payable under the applicable Pension Plan if
such benefit had been determined:

(i)
without regard to the benefit limitations under section 415 of the Code, and

(ii)
without regard to compensation limitation of section 401(a)(17) of the Code, and

(iii)
by including in Recognized Compensation, Earnings and Final Average Earnings (as
defined under the applicable Pension Plan) amounts not otherwise included
because they were deferred at the election of the Participating Employee under
the Alliant Techsystems Inc. Nonqualified Deferred Compensation Plan or any
other nonqualified deferred compensation plan at the time or times when they
would have been included but for such election to defer; and

(iv)
as adjusted pursuant to the terms of any employment agreement or any separate
written agreement between Orbital ATK (or an affiliate of Orbital ATK) and the
Participating Employee; minus

(b)
the amount actually paid from the applicable Pension Plan.

Notwithstanding anything to the contrary in the Plan, if the Participating
Employee is a Participant in the Orbital ATK, Inc. Pension and Retirement Plan
under the benefit structure formerly known as the ATK SEG Retirement Plan or the
Federal Cartridge Company Pension Plan, any service of such Participating
Employee before December 7, 2001, shall be disregarded for benefit accrual
purposes in determining any excess benefit provided under this Plan.
Notwithstanding anything to the contrary in the Plan, this Plan shall pay to
Participating Employees identified on Schedule 1 attached to the Plan who
terminate employment at or after age 55 the greater of (i) the amount determined
under this Section 4.1.1 or (ii) the amount determined under this Section 4.1.1
as of June 30, 2013 as if the applicable Pension Plan were the benefit structure
known as the ATK Pension Equity Formula under the Orbital ATK, Inc. Pension and
Retirement Plan plus the amount otherwise determined under Section 4.1.1 with
respect to service beginning July 1, 2013.

‑6‑

--------------------------------------------------------------------------------

Notwithstanding anything apparently to the contrary in this Plan, no benefit of
a Participating Employee who is a former employee of Alliant or any of its
affiliates and who is rehired by Orbital ATK, its predecessor, or any of its
affiliates on or after January 1, 2007 shall be attributable in whole or in part
to employment, services or compensation after such rehire date, except as and in
accordance with such terms as may be specified by the Personnel and Compensation
Committee of the Board of Directors of Orbital ATK.
4.1.2.    Form of Payment.
(a)
Except as otherwise provided in this Section 4.1.2, for any Participating
Employee who terminates employment and receives or begins to receive benefits
under the applicable Pension Plan on or before December 31, 2006, the benefit
under this Plan (minus any withholding and payroll taxes which must be deducted
therefrom) shall be paid to the Participating Employee in the same manner, at
the same time, for the same duration and in the same form as if such benefit has
been paid directly from the applicable Pension Plan. All elections and optional
forms of settlement in effect and all other rules governing the payment of
benefits under the applicable Pension Plan shall, to the extent practicable, be
given effect under this Plan so that the Participating Employee will receive
from a combination of the applicable Pension Plan and this Plan the same benefit
(minus the withholding, payroll and other taxes which must be deducted
therefrom) which would have been received under the applicable Pension Plan if
this Plan benefit had been paid from the applicable Pension Plan.

(b)
The provisions of subsection (a) of this Section 4.1.2 shall apply to any
Participating Employee who terminated employment before January 1, 2005 and
accrued no benefit under this Plan after December 31, 2004, but who does not
receive or begin to receive benefits under the applicable Pension Plan on or
before December 31, 2006.

(c)
Each Participating Employee identified on Schedule 2 attached to this Plan shall
be permitted to elect on or before December 31, 2005 to receive benefits under
this Plan in the form of a lump sum or any other form of payment available under
the applicable Pension Plan. Lump sum payments shall be calculated as of the
first day of the month following termination of employment, using the interest
rate and mortality table described in section 417(e) of the Code, as in effect
under the Pension Plan on the first day of the month following termination of
employment. Such payment shall be or begin to be made on the first day of the
seventh month following the month in which the Participating Employee terminates
employment if the Participating Employee is a “key employee,” within the meaning
of section 416(i) of the Code (disregarding section 416(i)(5)), or on the first
day of the first month following termination of employment if the Participating
Employee is not such a “key employee,” but in no event later than the later of
(i) the ninetieth

‑7‑

--------------------------------------------------------------------------------

day after whichever such date applies, or (ii) the last day of the calendar year
in which such date occurs. Lump sum payments to “key employees” shall be
credited with simple interest from the first day of the month following
termination of employment to the date of payment at the interest rate described
in section 417(e) of the Code, as in effect under the Pension Plan on the first
day of the month following termination of employment. In the case of payments in
a form other than a lump sum, the first such payment to a Participating Employee
who is a “key employee” shall include the amounts of the monthly payments for
the preceding six months. If a Participating Employee identified in Schedule 2
elects a joint and survivor annuity, and the Participating Employee’s joint
annuitant dies before payments begin, amounts otherwise payable as a joint and
survivor annuity shall be paid in the form of a single life annuity.
(d)
Each Participating Employee not described in subsections (a), (b) or (c) of this
Section 4.1.2, who terminates employment on or before December 31, 2006, shall
receive payment of benefits under this Plan in the form of a lump sum on the
later of (i) the earliest date after January 1, 2007 on which payment is
administratively practicable, or (ii) the first day of the seventh month
following termination of employment, but in neither case later than December 31,
2007. Lump sum payments shall be calculated as of January 1, 2007, using the
mortality table described in section 417(e) of the Code and an interest rate
that is the greater of 6% or the rate described in section 417(e) of the Code,
as in effect under the Pension Plan on that date, except that lump sums for
Participating Employees covered by the benefit structures known as (A) the
Alliant Techsystems Inc. Retirement Formula, the ATK Pension Equity Formula or
the ATK Cash Balance Formula under the Orbital ATK, Inc. Pension and Retirement
Plan, or (B) the Thiokol Pension Equity Formula or Thiokol Cash Balance Formula
under the Thiokol Propulsion Pension Plan, shall be their Account Balances (as
that term is defined under those benefit structures, respectively). Lump sum
payments made after January 31, 2007 shall be credited with simple interest for
the period from January 1, 2007 until the date of payment at a rate equal to the
greater of 6% or the rate described in section 417(e) of the Code, as in effect
under the Pension Plan on January 1, 2007.

(e)
Each Participating Employee not described in subsections (a), (b), (c), or (d)
of this Section 4.1.2 shall receive payment of benefits under this Plan in the
form of a lump sum on the later of (i) the first day of the seventh month
following the month in which the Participating Employee terminates employment or
(ii) February 1 of the calendar year following the calendar year in which the
Participating Employee terminates employment, but in neither case later than the
last day of the calendar year following the calendar year in which the
Participating Employee terminates employment. All lump sum amounts paid under
this Subsection (e) shall be determined as of the

‑8‑

--------------------------------------------------------------------------------

date of termination of employment, based on the mortality table described in
section 417(e) of the Code and an interest rate that is the greater of 6% or the
interest rate described in section 417(e) of the Code (as in effect under the
Pension Plan on the first day of the month following termination of employment),
except that lump sums for Participating Employees covered by the benefit
structures known as (A) the Alliant Techsystems Inc. Retirement Formula, the ATK
Pension Equity Formula or the ATK Cash Balance Formula under the Orbital ATK,
Inc. Pension and Retirement Plan, or (B) the Thiokol Pension Equity Formula or
Thiokol Cash Balance Formula under the Thiokol Propulsion Pension Plan, shall be
their Account Balances (as that term is defined under those benefit structures,
respectively). Simple interest will be credited for the period from the first
day of the month following termination of employment until the date of payment,
at a rate equal to the greater of 6% or the rate described in section 417(e) of
the Code, as in effect under the Pension Plan on the first day of the month
following termination of employment.
(f)
For purposes of Section 4.6.2 and subsections (d) and (e) of this Section 4.1.2,
for lump sums calculated using the stated interest and mortality factors, lump
sum amounts shall be determined on the basis of (i) the immediate annuity to
which the Participating Employee is entitled under the applicable Pension Plan
in the case of a Participating Employee who is entitled to an immediate annuity
under the applicable Pension Plan, or (ii) the annuity to which the
Participating Employee is entitled at Normal Retirement Age (as that term is
defined in the applicable Pension Plan) under the applicable Pension Plan in the
case of a Participating Employee who is not entitled to an immediate annuity
under the applicable Pension Plan.

(g)
Any reference in this Plan to termination of employment shall mean the
separation from service with Alliant and all entities treated as members of the
same controlled group with Alliant under section 414(b) or (c) of the Code.
Controlled group membership shall be determined by substituting “at least 50
percent” for “at least 80 percent” each place it appears in section 1563(a)(1),
(2) and (3) of the Code, and by substituting “at least 50 percent” for “at least
80 percent” each place it appears in Treas. Reg. § 1.414(c)-2.

4.2.    Benefit to Beneficiaries.
4.2.1.    Amount of Benefit. Unless the Participating Employee (i) is identified
on Schedule 2 attached to this Plan and has received or begun to receive his or
her benefits under this Plan prior to death, or (ii) has received a lump sum
under Section 4.1 hereof, there shall be paid under this Plan to the surviving
spouse or other joint or contingent annuitant or beneficiary the excess, if any,
of
(a)
the amount which would have been payable under the applicable Pension Plan if
such benefit had been determined:

‑9‑

--------------------------------------------------------------------------------

(i)
without regard to the benefit limitations of section 415 of the Code, and

(ii)
without regard to compensation limitation of section 401(a)(17) of the Code, and

(iii)
by including in Recognized Compensation, Earnings and Final Average Earnings (as
defined under the applicable Pension Plan) amounts not otherwise included
because they were deferred at the election of the Participating Employee under
the Alliant Techsystems Inc. Nonqualified Deferred Compensation Plan or any
other nonqualified deferred compensation plan at the time or times when they
would have been included but for such election to defer; and

(iv)
as adjusted pursuant to the terms of any employment agreement or any separate
written agreement between Orbital ATK and the Participating Employee; minus

(b)
the amount actually paid from the applicable Pension Plan.

4.2.2.    Form of Payment. Except as may be specifically provided in this Plan,
this benefit (minus any withholding and payroll taxes which must be deducted
therefrom) shall be paid to such person in the same manner, at the same time,
for the same duration and in the same form as if such benefit has been paid
directly from the applicable Pension Plan. All elections and optional forms of
settlement in effect and all other rules governing the payment of benefits under
the applicable Pension Plan shall, to the extent practicable, be given effect
under this Plan so that such person will receive from a combination of the
applicable Pension Plan and this Plan the same benefit (minus the withholding,
payroll and other taxes which must be deducted therefrom) if this Plan benefit
had been paid from the applicable Pension Plan. Notwithstanding the foregoing
provisions of this Section 4.2.2, in the event of the death of any Participating
Employee who (i) is not described in subsections (a), (b), or (c) of Section
4.1.2 or (ii) is described in subsection (c) of Section 4.1.2 but dies before
payment under this Plan has been made or begun, payment of any benefits under
this Section 4.2 shall be made in a lump sum, determined in accordance with
Section 4.1.2(d) or (e), as applicable, as soon as administratively practicable
after the Participating Employee’s death, but in no event later than the later
of the ninetieth day after the Participating Employee’s death or the last day of
the calendar year in which the Participating Employee’s death occurs.
4.3.    Special Rule for CECP. This Plan shall pay to Participating Employees
who are also entitled to benefits under the Alliant Techsystems Inc.
Supplementary Executive Retirement Plan for CECP Participants (see Appendix A)
the excess, if any, of:
(i)
the amount that would have been payable under the applicable Pension Plan if
such benefit had been determined without regard to the benefit limitations under
section 415 of the Code and without regard to compensation limitation of section
401(a)(17) of the Code plus, if applicable, the amount that would have been
payable if the

‑10‑

--------------------------------------------------------------------------------

amount of any deferred incentive award in the year in which the award would
otherwise have been paid by the Honeywell Inc. Corporate Executive Compensation
Plan would have been included under the definition of “Earnings” for purposes of
arriving at “Final Average Earnings,” over
(ii)
the amount actually paid from the applicable Pension Plan after taking into
account the benefit limitations under section 415 of the Code and the
compensation limitation of section 401(a)(17) of the Code plus, if applicable,
the amount actually paid from the Honeywell Inc. Corporate Executive
Compensation Plan for CECP Participants (Appendix A).

This benefit (minus any withholding and payroll taxes which must be deducted
therefrom) shall be paid to the Participating Employee in the same manner, at
the same time, for the same duration and in the same form as if such benefit has
been paid directly from the applicable Pension Plan. All elections and optional
forms of settlement in effect and all other rules governing the payment of
benefits under the applicable Pension Plan shall, to the extent practicable, be
given effect under this Plan so that the Participating Employee will receive
from a combination of the applicable Pension Plan and this Plan the same benefit
(minus the withholding, payroll and other taxes which must be deducted
therefrom) which would have been received under the applicable Pension Plan if
the limitation on benefits under section 415 of the Code, the compensation
limitation of section 401(a)(17) of the Code and the exclusion from the
definition of “Earnings” of the amount of any deferred incentive award had not
been in effect.
4.4.    Vesting. The benefit of a Participating Employee under this Plan shall
vest when the applicable Pension Plan vests, including any full (100%) vesting
due to a Change in Control (as defined under the applicable Pension Plan), or,
if earlier, pursuant to the terms of any employment agreement or separate
written agreement between Orbital ATK (or an affiliate of Orbital ATK) and the
Participating Employee.
4.5.    General Distribution Rules.
4.5.1.    Section 162(m) Determination. If a Participating Employee will receive
a lump sum under the Plan pursuant to Section 4.1 or Section 4.3 and if the PRC
(or, for any Section 16 Officer, the Board of Directors) determines that
delaying the time such payment is made would increase the probability that such
payment would be fully deductible for federal or state income tax purposes,
Orbital ATK may unilaterally delay the time of the making of such payment or any
portion of such payment until the earliest year during which Orbital ATK
reasonably anticipates that the payment will be fully deductible, but not later
than twenty‑four (24) months after the date such payment would otherwise be
payable.
4.5.2.    Exception for Small Benefits. Notwithstanding any other provision of
this Plan to the contrary, Orbital ATK shall pay any benefit which is payable
under this Plan to a Participating Employee or a Beneficiary in a lump sum
payment, at the time otherwise required under the terms of this Plan, if the
present value of the benefit (as determined under the actuarial

‑11‑

--------------------------------------------------------------------------------

factors for the applicable Pension Plan for such Participating Employee or
Beneficiary) is $50,000 or less, and the Participating Employee or Beneficiary
either has accrued a benefit under this Plan after December 31, 2004 or is not
receiving benefit payments under this Plan on or before December 31, 2005. In
the case of any Participating Employee or Beneficiary who accrued no benefit
under this Plan after December 31, 2004 and is receiving benefit payments under
this Plan on or before December 31, 2005, Orbital ATK, in its discretion, may
pay any remaining benefit which is payable under this Plan in a lump sum payment
if the present value of the benefit (as determined under the actuarial factors
for the applicable Pension Plan for such Participating Employee or Beneficiary)
is $50,000 or less. Notwithstanding any provisions of this Section 4.6.2 to the
contrary, lump sums for Participating Employees covered by the benefit
structures known as (A) the Alliant Techsystems Inc. Retirement Formula, the ATK
Pension Equity Formula or the ATK Cash Balance Formula under the Orbital ATK,
Inc. Pension and Retirement Plan, or (B) the Thiokol Pension Equity Formula or
Thiokol Cash Balance Formula under the Thiokol Propulsion Pension Plan, shall be
their Account Balances (as that term is defined under those benefit structures,
respectively).
SECTION 5

FUNDING
5.1.    Funding. Alliant shall be responsible for paying all benefits due
hereunder. Until all payments due under Section 4 are paid in full and for the
purpose of facilitating the payment of benefits due under those Sections,
Orbital ATK may (but shall not be required to) establish and maintain a grantor
trust pursuant to an agreement between Orbital ATK and a trustee selected by
Orbital ATK; provided, however, that any such grantor trust must be structured
so that it does not result in any federal income tax consequences to any
Participating Employee until such employee actually receives payments due under
Section 4. Orbital ATK may contribute to a grantor trust thereby created such
amounts as it may from time to time determine.
5.2.    Corporate Obligation. Neither Orbital ATK's officers nor any member of
its Board of Directors nor any member of the PRC in any way secures or
guarantees the payment of any benefit or amount which may become due and payable
hereunder to or with respect to any Participating Employee. Each Participating
Employee and other person entitled at any time to payments hereunder shall look
solely to the assets of Orbital ATK for such payments as an unsecured, general
creditor. After benefits shall have been paid to or with respect to a
Participating Employee and such payment purports to cover in full the benefit
hereunder, such former Participating Employee or other person or persons, as the
case may be, shall have no further right or interest in the other assets of
Orbital ATK in connection with this Plan. Neither Orbital ATK nor any of its
officers nor any member of its Boards of Directors nor any member of the PRC
shall be under any liability or responsibility for failure to effect any of the
objectives or purposes of the Plan by reason of the insolvency of Orbital ATK.

‑12‑

--------------------------------------------------------------------------------

SECTION 6

GENERAL MATTERS
6.1.    Amendment and Termination. Orbital ATK reserves the power to amend or
terminate this Plan either prospectively or retroactively or both:
(a)
in any respect by resolution of the Board of Directors of Orbital ATK; or

(b)
in any respect by action of the Personnel and Compensation Committee of the
Board of Directors of Alliant (or any successor committee); or

(c)
in any respect by action of any other committee or person determined by the
Board of Directors of Orbital ATK;

at any time and for any reason deemed sufficient by it without notice to any
person affected by this Plan and may likewise terminate or curtail the benefits
of this Plan both with regard to persons expecting to receive benefits in the
future and persons already receiving benefits at the time of such action;
provided, however, that Orbital ATK may not amend or terminate the Plan with
respect to benefits that have accrued and are vested pursuant to Section 4.3,
the applicable Pension Plan or an individual agreement between Orbital ATK and
the Participating Employee. No modification of the terms of this Plan shall be
effective unless it is in writing and signed on behalf of Orbital ATK by a
person authorized to execute such writing. No oral representation concerning the
interpretation or effect of this Plan shall be effective to amend the Plan.
6.2.    Limited Benefits. This Plan shall not provide any benefits with respect
to any defined contribution plan.
6.3.    Spendthrift Provision. No Participating Employee, surviving spouse,
joint or contingent annuitant or beneficiary shall have the power to transmit,
assign, alienate, dispose of, pledge or encumber any benefit payable under this
Plan before its actual payment to such person. The PRC shall not recognize any
such effort to convey any interest under this Plan. No benefit payable under
this Plan shall be subject to attachment, garnishment, execution following
judgment or other legal process before actual payment to such person.
6.4.    Errors in Computations. Orbital ATK shall not be liable or responsible
for any error in the computation of any benefit payable to or with respect to
any Participating Employee resulting from any misstatement of fact made by the
Participating Employee or by or on behalf of any survivor to whom such benefit
shall be payable, directly or indirectly, to Orbital ATK, and used by Orbital
ATK in determining the benefit. Orbital ATK shall not be obligated or required
to increase the benefit payable to or with respect to such Participating
Employee which, on discovery of the misstatement, is found to be understated as
a result of such misstatement of the Participating Employee. However, the
benefit of any Participating Employee which is overstated by reason of any such
misstatement or any other reason shall be reduced to the amount appropriate in
view of the truth (and to recover any prior overpayment).

‑13‑

--------------------------------------------------------------------------------

6.5.    Correction of Errors. If any Participating Employee in any written
statement required under the Plan document shall misstate such Participating
Employee’s age or the age of any person upon whose survival the payment of any
benefit in respect of such Participating Employee is contingent or any other
fact the misstatement of which would affect the amount of a benefit payable
hereunder, the accrual of benefits in respect of such Participating Employee
shall not be invalidated, but the amount of the benefit to be available with
respect to such Participating Employee will be adjusted retroactively to the
amount which would have been payable if such fact or facts had not been
misstated. It is recognized that errors may occur during the administration of
the Plan which may result in incorrect statement or payment of benefits. If an
administrative error occurs, the amount of benefits available to such
Participating Employee shall be the correct amount determined under the Plan
document and future benefits to such Participating Employee shall be adjusted to
reflect any prior mistakes under rules adopted by Orbital ATK. If no further
benefits are payable under the Plan, Orbital ATK will take whatever steps it
determines are reasonable to collect such overpayments on behalf of the Plan. In
no event will the Plan be liable to pay any greater benefit in respect of any
Participating Employee than that which would have been payable on the basis of
the truth and the provisions of this Plan document.
SECTION 7

FORFEITURE OF BENEFITS
All unpaid benefits under this Plan shall be permanently forfeited upon the
determination by Orbital ATK that the Participating Employee, either before or
after termination of employment:
(a)
engaged in a criminal or fraudulent conduct resulting in material harm to
Orbital ATK or an affiliate of Orbital ATK; or

(b)
made an unauthorized disclosure to any competitor of any material confidential
information, trade information or trade secrets of Orbital ATK or an affiliate
of Orbital ATK; or

(c)
provided Orbital ATK or an affiliate of Orbital ATK with materially false
reports concerning his or her business interests or employment; or

(d)
made materially false representations which are relied upon by Orbital ATK or an
affiliate of Orbital ATK in furnishing information to an affiliate, partner,
shareholders, accountants, auditor, a stock exchange, the Securities and
Exchange Commission or any regulatory or governmental agency; or

(e)
maintained an undisclosed, unauthorized and material conflict of interest in the
discharge of the duties owed by him or her to Orbital ATK or an affiliate of
Orbital ATK; or

(f)
engaged in conduct causing a serious violation of state and federal law by
Orbital ATK or an affiliate of Orbital ATK; or

‑14‑

--------------------------------------------------------------------------------

(g)
engaged in theft of assets or funds of Orbital ATK or an affiliate of Orbital
ATK; or

(h)
has been convicted of any crime which directly or indirectly arose out of his
her employment relationship with Orbital ATK or an affiliate of Orbital ATK or
materially affected his or her ability to discharge the duties of his or her
employment with Orbital ATK or an affiliate of Orbital ATK; or

(i)
engaged during his or her employment or within two (2) years after termination
of employment in any employment with a competitor, or engaged in any activity in
competition with Orbital ATK, without the consent of Orbital ATK.

SECTION 8

DETERMINATIONS AND CLAIMS PROCEDURE
8.1.    Determinations. The Personnel and Compensation Committee of Orbital
ATK’s Board of Directors (the “Committee”) and the Orbital ATK Pension and
Retirement Committee (“PRC”) shall make such determinations as may be required
from time to time in the administration of the Plan. The Committee and the PRC
shall have the final and conclusive discretionary authority and responsibility
to interpret and construe the Plan and to determine all factual and legal
questions under the Plan, including but not limited to the entitlement of
Participating Employees and Beneficiaries, and the amounts of their respective
interests. Each interested party may act and rely upon all information reported
to them hereunder and need not inquire into the accuracy thereof, nor be charged
with any notice to the contrary.
8.2.    Claims Procedure. Until modified by the Committee, the claims procedure
set forth in this Section 8 shall be the mandatory claims and review procedure
for the resolution of disputes and disposition of claims filed under the Plan.
8.2.1.    Original Claim. Any person may, if he or she so desires, file with the
PRC (or in the case of a Section 16 officer, the Committee) a written claim for
benefits under this Plan. Within ninety (90) days after the filing of such a
claim, the PRC (or the Committee for a Section 16 officer) shall notify the
claimant in writing whether the claim is upheld or denied in whole or in part or
shall furnish the claimant a written notice describing specific special
circumstances requiring a specified amount of additional time (but not more than
one hundred eighty (180) days from the date the claim was filed) to reach a
decision on the claim. If the claim is denied in whole or in part, the PRC (or
the Committee for a Section 16 officer) shall state in writing:
(a)
the specific reasons for the denial;

(b)
the specific references to the pertinent provisions of the Plan on which the
denial is based;

‑15‑

--------------------------------------------------------------------------------

(c)
a description of any additional material or information necessary for the
claimant to perfect the claim and an explanation of why such material or
information is necessary; and

(d)
an explanation of the claims review procedure set forth in this section.

8.2.2.    Review of Denied Claim. Within sixty (60) days after receipt of notice
that the claim has been denied in whole or in part, the claimant may file with
the Committee a written request for a review and may, in conjunction therewith,
submit written issues and comments. Within sixty (60) days after the filing of
such a request for review, the Committee shall notify the claimant in writing
whether, upon review, the claim was upheld or denied in whole or in part or
shall furnish the claimant a written notice describing specific special
circumstances requiring a specified amount of additional time (but not more than
one hundred twenty (120) days from the date the request for review was filed) to
reach a decision on the request for review.
8.2.3.    General Rules.
(a)
No inquiry or question shall be deemed to be a claim or a request for a review
of a denied claim unless made in accordance with the claims procedure. The PRC
may require that any claim for benefits and any request for a review of a denied
claim be filed on forms to be furnished by the PRC upon request.

(b)
All decisions on original claims shall be made by the PRC (or the Committee for
a Section 16 officer) and all decisions on requests for a review of denied
claims shall be made by the Committee.

(c)
the PRC and the Committee may, in their discretion, hold one or more hearings on
a claim or a request for a review of a denied claim.

(d)
A claimant may be represented by a lawyer or other representative (at the
claimant’s own expense), but the PRC and the Committee reserves the right to
require the claimant to furnish written authorization. A claimant’s
representative shall be entitled, upon request, to copies of all notices given
to the claimant.

(e)
The decision of the PRC (or the Committee for a Section 16 officer) on a claim
and a decision of the Committee on a request for a review of a denied claim
shall be served on the claimant in writing. If a decision or notice is not
received by a claimant within the time specified, the claim or request for a
review of a denied claim shall be deemed to have been denied.

(f)
Prior to filing a claim or a request for a review of a denied claim, the
claimant or his or her representative shall have a reasonable opportunity to
review a copy of the Plan and all other pertinent documents in the possession of
the PRC and the Committee.

‑16‑

--------------------------------------------------------------------------------

(g)
The PRC and the Committee may permanently or temporarily delegate its
responsibilities under this claims procedure to an individual or a committee of
individuals.

8.3.    Limitations and Exhaustion.
8.3.1.    Limitations. No claim shall be considered under these administrative
procedures unless it is filed with the PRC (or the Committee for a Section 16
officer) within one (1) year after the claimant knew (or reasonably should have
known) of the principal facts on which the claim is based. Every untimely claim
shall be denied by the PRC (or the Committee for a Section 16 officer) without
regard to the merits of the claim. No legal action (whether arising under
section 502 or section 510 of ERISA or under any other statute or non‑statutory
law) may be brought by any claimant on any matter pertaining to this Plan unless
the legal action is commenced in the proper forum before the earlier of:
(a)
two (2) years after the claimant knew (or reasonably should have known) of the
principal facts on which the claim is based, or

(b)
ninety (90) days after the claimant has exhausted these administrative
procedures.

Knowledge of all facts that a Participating Employee knew (or reasonably should
have known) shall be imputed to each claimant who is or claims to be a
Beneficiary of the Participating Employee (or otherwise claims to derive an
entitlement by reference to a Participating Employee) for the purpose of
applying the one (1) year and two (2) year periods.
8.3.2.    Exhaustion Required. The exhaustion of these administrative procedures
is mandatory for resolving every claim and dispute arising under this Plan. As
to such claims and disputes:
(a)
no claimant shall be permitted to commence any legal action relating to any such
claim or dispute (whether arising under section 502 or section 510 of ERISA or
under any other statute or non‑statutory law) unless a timely claim has been
filed under these administrative procedures and these administrative procedures
have been exhausted; and

(b)
in any such legal action all explicit and implicit determinations by the PRC and
the Committee (including, but not limited to, determinations as to whether the
claim was timely filed) shall be afforded the maximum deference permitted by
law.

act shall be held liable for the consequences thereof, except to the extent that
liability is imposed under ERISA.
9.4.    Delegation. The Committee and the members of the Committee and PRC shall
not be liable for an act or omission of another person with regard to a
responsibility that has been allocated to or delegated to such other person

Plan Statement.

‑18‑

--------------------------------------------------------------------------------

9.5.    Conflict of Interest. If any individual to whom authority has been
delegated or redelegated hereunder shall also be a Participating Employee in
this Plan, such Participating Employee shall have no authority with respect to
any matter specially affecting such Participating Employee’s individual rights
hereunder or the interest of a person superior to him or her in the organization
(as distinguished from the rights of all Participating Employees and
Beneficiaries or a broad class of Participating Employees and Beneficiaries),
all such authority being reserved exclusively to other individuals as the case
may be, to the exclusion of such Participating Employee, and such Participating
Employee shall act only in such Participating Employee’s individual capacity in
connection with any such matter.
9.6.    Administrator. Orbital ATK shall be the administrator for purposes of
section 3(16)(A) of ERISA.
9.7.    Service of Process. In the absence of any designation to the contrary by

certification or to give such notices or consents.
9.11.    Rules and Regulations. Any rule not in conflict or at variance with the
provisions hereof may be adopted by the PRC.
SECTION 10

CONSTRUCTION
10.1.    Defined Terms. Words and phrases used in this Plan with initial capital
letters, which are defined in the applicable Pension Plans’ documents and which
are not separately defined in this Plan shall have the same meaning ascribed to
them in the applicable Pension Plans’ documents unless in the context in which
they are used it would be clearly inappropriate to do so.
10.2.    ERISA Status. This Plan is maintained with the understanding that it is
a nonqualified deferred compensation plan for the benefit of a select group of
management or highly compensated employees within the meaning of section 201(2),
section 301(3) and section 401(a)(1) of ERISA. Each provision shall be
interpreted and administered accordingly. If any individually contracted
supplemental retirement arrangement with any Section 16 Officer is deemed to be
covered by

‑19‑

--------------------------------------------------------------------------------

ERISA, such arrangement shall be included in the Plan but only to the extent
that such inclusion is necessary to comply with ERISA.
10.3.    IRC Status. This Plan is intended to be a nonqualified deferred
compensation arrangement. The rules of section 401(a) et. seq. of the Code shall
not apply to this Plan. The rules of section 3121(v) and section 3306(r)(2) of
the Code shall apply to this Plan.
10.4.    Effect on Other Plans. This Plan shall not alter, enlarge or diminish
any person’s employment rights or obligations or rights or obligations under the
Pension Plans or any other plan. It is specifically contemplated that the
Pension Plans will, from time to time, be amended and possibly terminated. All
such amendments and termination shall be given effect under this Plan (it being
expressly intended that this Plan shall not lock in the benefit structures of
the Pension Plans as they exist at the adoption of this Plan or upon the
commencement of participation, or commencement of benefits by any Participating
Employee).
10.5.    Disqualification. Notwithstanding any other provision of this Plan or
any election or designation made under the Plan, any individual who feloniously
and intentionally kills a Participating Employee shall be deemed for all
purposes of this Plan and all elections and designations made under this Plan to
have died before such Participating Employee. A final judgment of conviction of
felonious and intentional killing is conclusive for this purpose. In the absence
of a conviction of felonious and intentional killing, the PRC shall determine
whether the killing was felonious and intentional for this purpose.
10.6.    Rules of Document Construction. Whenever appropriate, words used herein
in the singular may be read in the plural, or words used herein in the plural
may be read in the singular; the masculine may include the feminine; and the
words “hereof,” “herein” or “hereunder” or other similar compounds of the word
“here” shall mean and refer to the entire Plan and not to any particular
paragraph or Section of this Plan unless the context clearly indicates to the
contrary. The titles given to the various Sections of this Plan are inserted for
convenience of reference only and are not part of this Plan, and they shall not
be considered in determining the purpose, meaning or intent of any provision
hereof.
10.7.    References to Laws. Any reference in this Plan to a statute or
regulation shall be considered also to mean and refer to any subsequent
amendment or replacement of that statute or regulation.
10.8.    Effect on Employment. Neither the terms of this Plan nor the benefits
hereunder nor the continuance thereof shall be a term of the employment of any
employee. Except as provided in Section 6.1, Alliant shall not be obliged to
continue the Plan. The terms of this Plan shall not give any employee the right
to be retained in the employment of any Employer.
10.9.    Choice of Law. This instrument has been executed and delivered in the
Commonwealth of Virginia and has been drawn in conformity to the laws of that
Commonwealth and shall, except to the extent that federal law is controlling, be
construed and enforced in accordance with the laws of the Commonwealth of
Virginia.

This Plan, as amended and restated herein, was adopted by the Personnel and
Compensation Committee of the Board of Directors of Orbital ATK, Inc. on this
22nd day of December, 2015.
