this provision, no claim by the Company that Cause exists shall be given effect unless the Board determines that it has been established

SECTION 2. BENEFITS.

 

2.1.                  Severance
Payments and Benefits. Each Severed Employee shall be entitled, subject to Section 2.4, to receive the following payments and
benefits from the Company.

 

(a)            Severance
Pay. A lump sum cash amount (the “Severance Pay”) equal to the sum of (i) the product of (A) the sum
of (1) the Severed Employee’s annual base salary, and (2) the Severed Employee’s target annual cash incentive compensation
as in effect immediately prior to the Change in Control, and (B) the Applicable Multiplier, and (ii) the product of (A) such
target annual cash incentive compensation and (B) a fraction, the numerator of which is the number of days elapsed through the Severance
Date in the fiscal year during which the Severance Date occurs and the denominator of which is 365 (or 366, if such fiscal year is a leap
year). For purposes of this Section 2.1(a), annual base salary shall be the higher of the Severed Employee’s (x) base
monthly salary in the calendar month immediately preceding a Change in Control and (y) base monthly salary in the calendar month
immediately preceding the Severed Employee’s Severance Date (in each case, without regard to any reductions therein which constitute
Good Reason), multiplied by twelve (12).

 

(b)            Benefits.
During the Applicable Period, the Company shall arrange to provide the Severed Employee and anyone entitled to claim through the Severed
Employee life, accident and health (including medical, behavioral, prescription drug, dental and vision) benefits substantially similar
to those provided to the Severed Employee and anyone entitled to claim through the Severed Employee immediately prior to the Severed Employee’s
Severance Date or, if more favorable to the Severed Employee, those provided to the Severed Employee and those entitled to claim through
the Severed Employee immediately prior to the first occurrence of an event or circumstance constituting Good Reason, at no greater after-tax
cost to the Severed Employee than the after tax cost to the Severed Employee immediately prior to such Severance Date or occurrence.

 

    5

     

    

 

(c)            DC
Pension Plans. In addition to the retirement benefits to which the Severed Employee is entitled under each DC Pension Plan, the Company
shall pay the Severed Employee a lump sum cash amount equal to the product of (i) the annual value of Company contributions or allocations
(excluding any employee deferrals or contributions, Transitional Contributions, and earnings) to all DC Pension Plans, on behalf of the
employee (determined based on the rate of contributions and allocations in effect as of immediately prior to such Change in Control, but
assuming such contributions and allocations are applied to the annualized base salary plus target annual cash incentive compensation as
determined in Section 2.1(a)) and (ii) the Applicable Multiplier.

 

(d)            DB
Pension Plans. If the Severed Employee would have become eligible for an early retirement subsidy with respect to such Severed Employee’s
retirement benefits under any DB Pension Plan had the Severed Employee remained employed through the end of the Applicable Period, in
addition to the retirement benefits to which the Severed Employee is entitled under each DB Pension Plan, the Company shall pay the Severed
Employee a lump sum cash amount equal to the excess of the actuarial equivalent of the aggregate retirement pension (taking into account
any early retirement subsidies associated therewith and determined in accordance with the normal form of payment under each DB Pension
Plan, commencing at the date on or after the last day of the Applicable Period as of which the actuarial equivalent of such form of payment
is greatest) which the Severed Employee would have accrued and vested in under the terms of all DB Pension Plans determined:

 

(i)             without
regard to any amendment to any DB Pension Plan made subsequent to a Change in Control and on or prior to the date of the Severed Employee’s
Severance Date, which amendment adversely affects in any manner the computation of retirement benefits thereunder, and

 

(ii)            solely
for purposes of determining eligibility for pension benefits, including all applicable retirement subsidies, as if the Severed Employee
had accumulated (after the Severed Employee’s Severance Date) the number of additional months of age and service credit thereunder
that the Severed Employee would have accumulated had the Severed Employee remained employed by the Company during the Applicable Period;
over the actuarial equivalent of the aggregate retirement pension (taking into account any early retirement subsidies associated therewith
and determined in accordance with the normal form of payment under each DB Pension Plan, commencing at the date on or after the Severed
Employee’s Severance Date as of which the actuarial equivalent of such form of payment is greatest) that the Severed Employee had
accrued and vested in pursuant to the provisions of the DB Pension Plans as of the Severed Employee’s Severance Date.

 

For purposes of this Section 2.1(d), “actuarial equivalent”
shall be determined based upon the Severed Employee’s age as of the Severed Employee’s Severance Date using the same assumptions
utilized under the Howmet Aerospace Retirement Plan I, Section 8.3(d)(ii) or the successor to such provision (without regard
to applicable dollar limitations ($5,000 as of the Effective Date)) immediately prior to the Severed Employee’s Severance Date or,
if more favorable to the Severed Employee, immediately prior to the first occurrence of an event or circumstance constituting Good Reason.

 

(e)            Post-Retirement
Benefit Plans. If the Severed Employee would have become entitled to benefits under the Company’s post-retirement health care
plans, as in effect immediately prior to the Severed Employee’s Severance Date or, if more favorable to the Severed Employee, as
in effect immediately prior to the first occurrence of an event or circumstance constituting Good Reason, had the Severed Employee’s
employment terminated at any time during the Applicable Period, the Company shall provide such post-retirement health care benefits to
the Severed Employee and the Severed Employee’s dependents commencing on the later of (i) the date on which such coverage would
have first become available in accordance with the terms of the applicable plan and (ii) the date on which benefits described in
Section 2.1(b) terminate, and ending upon the death of the Eligible Employee. Any such benefit that is dependent on service
or compensation shall be determined as if the Severed Employee had accumulated (after the Severed Employee’s Severance Date) the
number of additional months of age and service credit thereunder that the Severed Employee would have accumulated had the Severed Employee
remained employed by the Company through the end of the Applicable Period, and as if the Severed Employee had been credited with compensation
for each full calendar month following the calendar month of the Severed Employee’s Severance Date up to the end of the Applicable
Period equal to the Severed Employee’s annualized based salary as determined in Section 2.1(a), plus the Severed Employee’s
target annual cash incentive compensation as determined in Section 2.1(a), divided by twelve (12). Except for the additional service
and compensation credit during the Applicable Period, nothing herein is intended to provide the Severed Employee with benefits that exceed
the benefits provided to other participants in the applicable post-retirement health care plans, as in effect from time to time.

 

    6

     

    

 

(f)            The
Company shall provide the Severed Employee with reasonable outplacement services suitable to the Severed Employee’s position through
the date that is six (6) months following the Severed Employee’s Severance Date or, if earlier, the date on which the Severed
Employee first accepts an offer of employment from a new employer.

 

(g)           The
amounts described in Sections 2.1(a), (c) and (d) shall be paid to the Eligible Employee in a cash lump sum as soon as practicable
after the Severance Date but in no event later than thirty (30) days after the Severance Date; provided that, if the
Severed Employee is, as of the Severance Date, a “specified employee” within the meaning of Section 409A of the Code
as determined in accordance with the methodology duly adopted by the Company as in effect on the Severance Date, then such lump sum amounts
shall instead be paid on the first business day that is at least six (6) months after the Severance Date (or if sooner, upon the
death of the Severed Employee) (the “Delayed Payment Date”), with interest at the applicable federal rate provided
for in Section 7872(f)(2)(A) of the Code, from the first business day after the Severance Date through the Delayed Payment Date.

 

2.2.           Reduction
of Certain Payments.

 

(a)            Anything
in this Plan to the contrary notwithstanding, if the Accounting Firm (as defined below) shall determine that receipt of all Payments (as
defined below) of any Severed Employee would subject the Severed Employee to the Excise Tax, the Accounting Firm shall determine whether
to reduce any of the Payments paid or payable pursuant to this Plan (the “Plan Payments”) so that the Parachute Value
(as defined below) of all Payments, in the aggregate, equals the Safe Harbor Amount (as defined below). The Plan Payments shall be so
reduced only if the Accounting Firm determines that the Severed Employee would have a greater Net After-Tax Receipt (as defined below)
of aggregate Payments if the Plan Payments were so reduced. If the Accounting Firm determines that the Severed Employee would not have
a greater Net After-Tax Receipt of aggregate Payments if the Plan Payments were so reduced, the Severed Employee shall receive all Plan
Payments to which the Participant is entitled hereunder.

 

(b)            If
the Accounting Firm determines that aggregate Plan Payments should be reduced so that the Parachute Value of all Payments, in the aggregate,
equals the Safe Harbor Amount, the Company shall promptly give the Severed Employee notice to that effect and a copy of the detailed calculation
thereof. All determinations made by the Accounting Firm under this Section 2.2 shall be binding upon the Company, its Affiliates
and the Severed Employee and shall be made as soon as reasonably practicable and in no event later than fifteen (15) days following the
Severance Date. For purposes of reducing the Plan Payments so that the Parachute Value of all Payments, in the aggregate, equals the Safe
Harbor Amount, only amounts payable under the Plan (and no other Payments) shall be reduced. The reduction of the amounts payable hereunder,
if applicable, shall be made by reducing the Plan Payments that have a Parachute Value in the following order: Section 2.1(c), Section 2.1(d),
Section 2.1(a), Section 2.1(b), Section 2.1(e), Section 2.1(f), in each case, beginning with payments or benefits
that do not constitute non-qualified deferred compensation and reducing payments or benefits in reverse chronological order beginning
with those that are to be paid or provided the farthest in time from the Severance Date, based on the Accounting Firm’s determination.
All reasonable fees and expenses of the Accounting Firm shall be borne solely by the Company.

 

    7

     

    

 

(c)            To
the extent requested by the Severed Employee, the Company and its Affiliates shall cooperate with the Severed Employee in good faith in
valuing, and the Accounting Firm shall take into account the value of, services provided or to be provided by the Severed Employee (including,
without limitation, the Severed Employee’s agreeing to refrain from performing services pursuant to a covenant not to compete or

of the initial ninety (90)-day period, indicating the special circumstances requiring an extension and the date by which the Committee
expects to render its decision), send a written notification to the Eligible Employee as to its disposition. In the event the claim is

the event that an Eligible Employee wishes to appeal the denial of his or her claim he or she may request a review of such denial by making
application in writing to the Committee within sixty (60) days after receipt of such denial. An Eligible Employee (or his or her
duly authorized legal representative) shall be provided, upon written request to the Committee and free of charge, reasonable access to,
and copies of, all documents, records or other information in the Company’s possession relevant to his or her claim and may submit
comments, documents, records and other information relating to the claim, which shall be taken into account by the Committee in reviewing
its denial of the Eligible Employee’s claim, without regard to whether such information was submitted or considered in the initial
claim.

 

(c)            Within
sixty (60) days after receipt of a written appeal (unless special circumstances require an extension of up to sixty (60) days, in

CPR Institute for Dispute Resolution (“CPR”) in accordance with the CPR’s rules then in effect; provided,

upon the Company’s cost of providing benefits under the Plan, or (c) that do not change or alter the character and intent of
the Plan; and provided, further that the Plan may not be terminated, or amended in any manner that adversely
affects any Eligible Employee (other than an Eligible Employee whose employment with the Company and its Subsidiaries commences subsequent

of a specific contemplated Change in Control.

 

SECTION 4. GENERAL PROVISIONS.

 

4.1.            Except
as otherwise provided herein or by law, no right or interest of any Eligible Employee under the Plan shall be assignable or transferable,
in whole or in part, either directly or by operation of law or otherwise, including, without limitation, by execution, levy, garnishment,
attachment, pledge or in any manner. No attempted assignment or transfer of any such right or interest shall be effective, and no right
or interest of any Eligible Employee under the Plan shall be liable for, or subject to, any obligation or liability of such Eligible Employee.
The Plan shall inure to the benefit of, and be binding upon, the Company and its successors and assigns. The Company will require any
successor (whether direct or indirect, by purchase, merger, consolidation or otherwise) to all or substantially all of the business and/or
assets of the Company to assume expressly and agree to perform the obligations set forth in the Plan in the same manner and to the same
extent as the Company would be required to do so.

 

4.2.            Neither
the establishment of the Plan, nor any modification thereof, nor the creation of any fund, trust or account, nor the payment of any benefits
shall be construed as giving any Eligible Employee, or any person whomsoever, the right to be retained in the service of the Company,
and all Eligible Employees shall remain subject to discharge to the same extent as if the Plan had never been adopted.

 

4.3.            If
any provision of this Plan shall be held invalid or unenforceable, such invalidity or unenforceability shall not affect any other provisions
hereof, and this Plan shall be construed and enforced as if such provisions had not been included.

 

4.4.            If
a Severed Employee dies while any amount is still payable to such Severed Employee, all such amounts, unless otherwise provided herein,
shall be paid in accordance with the terms of this Plan to the executor, personal representative or administrators of the Severed Employee’s
estate.

 

4.5.            The
headings and captions herein are provided for reference and convenience only, shall not be considered part of the Plan, and shall not
be employed in the construction of the Plan.

 

4.6.            The
Plan shall not be funded. No Eligible Employee shall have any right to, or interest in, any assets of the Company which may be applied
by the Company to the payment of benefits or other rights under this Plan.

 

4.7.            Any
notice or other communication required or permitted pursuant to the terms hereof shall be in writing and shall be deemed to have been
duly given when personally delivered or when mailed by United States certified mail, return receipt requested, or by overnight courier,
postage prepaid, to the Company at its corporate headquarters address, to the attention of the Chief Legal Officer of the Company, or
to the Eligible Employee at the Eligible Employee’s most recent home address reflected on the books and records of the Company.

 

    11

     

    

 

4.8.            This
Plan shall be construed and enforced according to the laws of the State of Delaware, without regard to its principles of conflicts of
law.

 

4.9.            Payments
to a Severed Employee under this Plan shall be in lieu of any severance or similar payments that otherwise might be payable under any
plan, program, policy or agreement sponsored or maintained by the Company that provides severance benefits to employees upon termination
of employment, except that the payment or acceleration of equity or equity-based awards shall be in addition to, rather than in lieu of,
any payment or benefits due under the Plan.

 

4.10.          The
obligations under this Plan are intended to comply with the requirements of Section 409A of the Code or an exemption or exclusion
therefrom and shall in all respects be administered in accordance with Section 409A of the Code. Each payment of compensation under
this Plan shall be treated as a separate payment of compensation for purposes of applying Section 409A of the Code. All payments
to be made upon a termination of employment under this Plan may only be made upon a “separation from service” under Section 409A
of the Code to the extent necessary in order to avoid the imposition of penalty taxes on a Severed Employee pursuant to Section 409A
of the Code. In no event may a Severed Employee, directly or indirectly, designate the calendar year of any payment under this Plan. Notwithstanding
anything to the contrary in this Plan, all reimbursements and in-kind benefits provided under this Plan that are subject to Section 409A
of the Code shall be made in accordance with the requirements of Section 409A of the Code, including without limitation, where applicable,
the requirement that (a) the amount of expenses eligible for reimbursement, or in-kind benefits provided, during a calendar year
may not affect the expenses eligible for reimbursement, or in-kind benefits to be provided, in any other calendar year; (b) the reimbursement
of any eligible fees and expenses shall be made no later than the last day of the calendar year following the year in which the applicable
fees and expenses were incurred; and (c) the right to reimbursement or in-kind benefits is not subject to liquidation or exchange
for another benefit.
