APPENDIX A

 

TERMS AND CONDITIONS OF
PERFORMANCE UNITS

 

1.           Award.
The Company hereby awards to the Employee under the Plan as a separate incentive in connection with his or her employment, and
not in lieu of any salary or other compensation for his or her services, an award of (Your Target Grant) Performance Units on the
date hereof, subject to all of the terms and conditions in this Agreement and the Plan.

 

2.           Vesting.
To the extent that the Performance Goals are achieved and Shares are earned (which may range from
zero to (Potential Maximum)), as determined and certified by the Committee in its sole discretion, then the earned Shares shall
be paid following the end of the Performance Period no later than _________ immediately following the end of the Performance Period
(the “Settlement Date”) provided that Employee shall have been continuously employed by the Company or by one of its
Affiliates from the Grant Date through the last day of the Performance Period (the “Employment Requirement”). For
the avoidance of doubt, in the event that the Employment Requirement is waived pursuant to Paragraph 3, 4 or 6, except as set
forth in Paragraph 7, payout of the Performance Units shall continue to depend on the extent to which the Performance Goals are
achieved and Shares are earned, as determined and certified by the Committee in its sole discretion.

 

3.           Retirement
If Employee has a Termination of Service due to Retirement (defined as 55 years or more of age
with 10 or more years of service with the Company or its Affiliates, or age 65 or older) on or prior to the last day of the Performance
Period, Employee shall be treated for purposes of this Agreement as having been continuously employed by the Company or by one
of its Affiliates through the last day of the Performance Period; provided, however, that the threshold, target and maximum number
of Performance Units subject to this Agreement (and potential payouts in between) shall be adjusted proportionally by the time
during the three (3) year Performance Period that the Employee remained an employee of the Company (based upon a 365 day year). 
For example, if the Employee is granted a target number of Performance Units equal to 6,000 and the Employee Terminated Service
due to the Employee's Retirement 30 days after the Grant Date, then the Employee's target number of Performance Units would be
reduced from 6,000 shares to 164 shares (6,000 x 30/1,095) and the balance of the Performance Units would be cancelled. For
the avoidance of doubt, except as set forth in Paragraph 7, the actual number of Shares earned with respect to such adjusted number
of Performance Units shall continue to depend on the extent to which the Performance Goals are achieved and Shares are earned,
as determined and certified by the Committee in its sole discretion.

 

4.           Committee
Discretion. The Committee, in its absolute discretion, may waive the Employment Requirement with respect to all or any portion
of the Performance Units at any time.

 

5.           Forfeiture.
Except as provided in Paragraphs 3, 4, 6 or 7(b) and notwithstanding any contrary provision of this Agreement, in the event that
Employee ceases to be continuously employed by the Company or by one of its Affiliates through the last day of the Performance
Period, the Performance Units shall thereupon be forfeited.

 

6.           Death
or Disability of Employee. In the event of the Employee's death prior to Employee's Termination of Service or Termination of
Service due to Disability, Employee shall be treated for purposes of this Agreement as having been continuously employed by the
Company or by one of its Affiliates through the last day of the Performance Period. Any distribution or delivery to be made to
the Employee under this Agreement shall, if the Employee is then deceased, be made to the Employee’s designated beneficiary,
or if either no beneficiary survives the Employee or the Committee does not permit beneficiary designations, to the administrator
or executor of the Employee’s estate. Any designation of a beneficiary by the Employee shall be effective only if such designation
is made in a form and manner acceptable to the Committee. Any transferee must furnish the Company with (a) written notice of his
or her status as transferee, and (b) evidence satisfactory to the Company to establish the validity of the transfer and compliance
with any laws or regulations pertaining to said transfer.

 

     

     

    

 

7.           Change
in Control.

 

(a)           In the event of a Change in Control
(defined below) in which the Performance Units are assumed, the Performance Goals shall be deemed to be satisfied at target and
the target number of Shares (as adjusted pursuant to Section 12 hereof) shall be paid to the Employee on the Settlement Date provided
that Employee shall have been continuously employed by the Company or by one of its Affiliates from the Grant Date through the
last day of the original Performance Period (or shall have had an earlier Termination of Service due to Retirement or death or
as described in the second to last sentence of this Section 7(a)). In the event Employee shall have had an earlier Termination
of Service due to Retirement, such target number of Shares shall be prorated in accordance with Paragraph 3 hereof. If Employee
has entered into a Change in Control Agreement (the “CIC Agreement”) with the Company on or prior to the date of the
applicable Change in Control and the Employee’s employment terminates under the circumstances described in Section 2(d) or
4(a) of the CIC Agreement, then Employee shall become vested in the target number of Shares (as adjusted pursuant to Section 12
hereof, if applicable) upon the Release Deadline (as defined in the CIC Agreement) provided that Employee shall have executed and
not revoked the Release (as defined in the CIC Agreement) by the Release Deadline and such Shares shall be paid to the Employee
on the Settlement Date; provided, however, that if a Change in Control is not consummated by the Release Deadline, Employee shall
not be entitled to any payments or benefits on account of Employee’s termination described in such Section 2(d). In the event
of any conflict between this Agreement and CIC Agreement, this Agreement shall control.

 

(b)           Notwithstanding
the foregoing or anything to the contrary set forth in the Plan or any other agreement or arrangement, in the event that the Performance
Units are not assumed in connection with a Change in Control, the Performance Goals shall be deemed satisfied at target and the
target number of Shares shall be paid to the Employee on the Settlement Date in the same form, and determined in accordance with
the undiscounted value of, the consideration received by the holders of Shares in the Change in Control without the requirement
that Employee shall have been continuously employed by the Company or by one of its Affiliates from the Grant Date through the
last day of the original Performance Period and without the requirement that any portion of such payment be subject to any escrow,
earn-out or similar provision.

 

For purposes of this Agreement, Change in
Control shall mean the occurrence of any of the following:

 

(i) Any individual or group constituting a
“person”, as such term is used in Sections 13(d) and 14(d)(2) of the Securities Exchange Act of 1934, as amended, (other
than (A) the Company or any of its subsidiaries or (B) any trustee or other fiduciary holding securities under an employee
benefit plan of the Company or of any of its subsidiaries), is or becomes the beneficial owner, directly or indirectly, of securities
of the Company representing thirty percent (30%) or more of the combined voting power of the Company’s outstanding securities
then entitled ordinarily (and apart from rights accruing under special circumstances) to vote for the election of directors; or

 

     

     

    

 

(ii) Continuing Directors (directors of the
Company in office on the date hereof and any successor to any such director who was nominated or selected by a majority of the
Continuing Directors in office at the time of the director’s nomination or selection and who is not an “affiliate”
or “associate” (as defined in Regulation 12B under the Securities Exchange Act of 1934, as amended) of any person who
is the beneficial owner, directly or indirectly, of securities representing ten percent (10%) or more of the combined voting
power of the Company’s outstanding securities then entitled ordinarily to vote for the election of directors) cease to constitute
at least a majority of the Board; or

 

(iii) there occurs a reorganization, merger,
consolidation or other corporate transaction involving the Company (a “Transaction”), in each case with respect to
which the stockholders of the Company immediately prior to such Transaction do not, immediately after the Transaction, own more
than 50% of the combined voting power of the Company or other corporation resulting from such Transaction; or

 

(iv) all or substantially all of the assets
of the Company are sold, liquidated or distributed;

 

provided, however, that a “Change in Control”
shall not be deemed to have occurred under this Agreement if, prior to the occurrence of a specified event that would otherwise
constitute a Change in Control hereunder, the disinterested Continuing Directors then in office, by a majority vote thereof, determine
that the occurrence of such specified event shall not be deemed to be a Change in Control with respect to Employee hereunder if
the Change in Control results from actions or events in which Employee is a participant in a capacity other than solely as an officer,
employee or director of the Company.

 

8.           Settlement
of Performance Units; Dividend Equivalents.

 

a)            Status
as a Creditor. Prior to settlement of any vested Performance Units, the Performance Units will represent an unfunded and unsecured
obligation of the Company, payable (if at all) only from the general assets of the Company. The Employee is an unsecured general
creditor of the Company, and settlement of vested Performance Units is subject to the claims of the Company’s creditors.

 

b)           Form
and Timing of Settlement. Performance Units will automatically be settled in the form of Shares on the Settlement Date to
the extent earned in accordance with the terms hereof. Fractional Shares will not be issued with respect to Performance Units.
Where a fractional Share would be owed to the Employee with respect to vested Performance Units, a cash payment equivalent will
be paid in place of any such fractional Share using the Fair Market Value on the relevant Settlement Date.

 

c)           Dividend
Equivalents. In the event that the Company declares a cash dividend on its Shares having a record date on or after the Grant
Date and prior to the date the vested Performance Units are settled, an amount equal to the per Share cash dividend(s) multiplied
by the number of Shares earned and payable under the Performance Units granted to Employee under this Agreement, if any, shall
be accrued on the Employee’s behalf and paid in cash to Employee at the same time and otherwise under the same terms and
conditions as apply to such earned and payable Performance Units.

 

     

     

    

 

9.           Tax
Liability and Withholding. The Company or one if its Affiliates shall assess applicable tax liability and requirements in connection
with the Employee’s participation in the Plan, including, without limitation, tax liability associated with the grant or
settlement of Performance Units or sale of the underlying Shares (the “Tax Liability”). These requirements may change
from time to time as laws or interpretations change. Regardless of the Company’s or the Affiliate’s actions in this
regard, the Employee hereby acknowledges and agrees that the Tax Liability shall be the Employee’s responsibility and liability.
The Employee acknowledges that the Company’s obligation to issue or deliver Shares shall be subject to satisfaction of the
Tax Liability. Unless otherwise determined by the Company, Tax Liability shall be satisfied by the Company’s withholding
all or a portion of any Shares that otherwise would be issued to the Employee upon settlement of the vested Performance Units;
provided that amounts withheld shall not exceed the amount necessary to satisfy the Company’s tax withholding obligations
(minimum tax withholding obligations if necessary to avoid adverse accounting consequences). Such withheld Shares shall be valued
based on the Fair Market Value as of the date the withholding obligations are satisfied. The Company or one if its Affiliates may,
at their discretion, use other methods to satisfy the Tax Liability. Furthermore, the Employee agrees to pay the Company or the
Affiliate any Tax Liability that cannot be satisfied by the foregoing methods.

 

10.         Rights
as Stockholder. Neither the Employee nor any person claiming under or through the Employee shall have any of the rights or
privileges of a stockholder of the Company in respect of any Performance Units (whether vested or unvested) unless and until such
Performance Units are settled in Shares and certificates representing such Shares shall have been issued, recorded on the records
of the Company or its transfer agents or registrars, and delivered to the Employee. After such issuance, recordation and delivery,
the Employee shall have all the rights of a stockholder of the Company with respect to voting such Shares and receipt of dividends
and distributions on such Shares.

 

11.         Acknowledgments.
The Employee acknowledges and agrees to the following:

 

		·	The Plan is discretionary in nature and the Committee may amend, suspend, or terminate it at any time;

 

		·	The grant of the Performance Units is voluntary and occasional and does not create any contractual or other right to receive
future grants of Performance Units, or benefits in lieu of the Performance Units even if the Performance Units have been granted
repeatedly in the past;

 

		·	All determinations with respect to such future Performance Units, if any, including but not limited to, the times when
the Performance Units shall be granted or when the Performance Units shall vest, will be at the sole discretion of the Committee;

 

		·	The Employee’s participation in the Plan is voluntary;

 

		·	The value of the Performance Units is an extraordinary item of compensation, which is outside the scope of the Employee’s
employment contract (if any), except as may otherwise be explicitly provided in the Employee’s employment contract (if any);

 

     

     

    

 

		·	The Performance Units are not part of normal or expected compensation or salary for any purpose, including, but not
limited to, calculating termination, severance, resignation, redundancy, end of service, or similar payments, or bonuses, long-service
awards, pension or retirement benefits;

 

		·	The future value of the Shares is unknown and cannot be predicted with certainty;

 

		·	No claim or entitlement to compensation or damages arises from the termination of the Award or diminution in value of
the Performance Units or Shares, and the Employee irrevocably releases the Company and its Affiliates from any such claim that
may arise;

 

		·	Neither the Plan nor the Performance Units shall be construed to create an employment relationship where any employment relationship
did not otherwise already exist;

 

		·	Nothing in this Agreement or the Plan shall confer upon the Employee any right to continue to be employed by the Company or
any Affiliate or shall interfere with or restrict in any way the rights of the Company or the Affiliate, which are hereby expressly
reserved, to terminate the employment of the Employee under applicable law;

 

		·	The transfer of employment of the Employee between the Company and any one of its Affiliates (or between Affiliates) shall
not be deemed a Termination of Service;

 

		·	Nothing herein contained shall affect the Employee’s right to participate in and receive benefits under and in accordance
with the then current provisions of any pension, insurance or other employee welfare plan or program of the Company or any Affiliate.

 

12.         Changes
in Stock. In the event that as a result of a stock dividend, stock split, reclassification, recapitalization, combination of
Shares or the adjustment in capital stock of the Company or otherwise, or as a result of a merger, consolidation, spin-off or other
reorganization, the Company’s common stock shall be increased, reduced or otherwise changed, the Performance Units shall,
subject to Section 409A of the Code, be properly adjusted.

 

13.         Address
for Notices. Any notice to be given to the Company under the terms of this Agreement shall be addressed to the Company, in

in writing.

 

14.         Restrictions
on Transfer. Except as provided in Paragraph 6 above, this award and the rights and privileges
conferred hereby shall not be transferred, assigned, pledged or hypothecated in any way (whether by operation of law or otherwise)
and shall not be subject to sale under execution, attachment or similar process. Upon any attempt to transfer, assign, pledge,
hypothecate or otherwise dispose of this award, or of any right or privilege conferred hereby, or upon any attempted sale under
any execution, attachment or similar process, this award and the rights and privileges conferred hereby immediately shall become
null and void. Regardless of whether the transfer or issuance of the Shares to be issued pursuant to this Agreement has been registered
under the Securities Act of 1933, as amended (the "1933 Act") or has been registered or qualified under the securities
laws of any state, the Company may impose additional restrictions upon the sale, pledge, or other transfer of the Shares (including
the placement of appropriate legends on stock certificates and the issuance of stop-transfer instructions to the Company’s
transfer agent) if, in the judgment of the Company and the Company’s counsel, such restrictions are necessary in order to
achieve compliance with the provisions of the 1933 Act, the securities laws of any state, or any other law. Stock certificates
evidencing the Shares issued pursuant to this Agreement, if any, may bear such restrictive legends as the Company and the Company’s
counsel deem necessary under applicable laws or pursuant to this Agreement.

 

     

     

    

 

15.         Binding
Agreement. Subject to the limitation on the transferability of this award contained herein, this Agreement shall be binding
upon and inure to the benefit of the heirs, legatees, legal representatives, successors and assigns of the parties hereto.

 

16.         Conditions
for Issuance of Certificates for Stock. The Shares deliverable to the Employee upon settlement of vested Performance Units
may be either previously authorized but unissued Shares or issued Shares which have been reacquired by the Company. Subject to
Section 409A of the Code, the Company shall not be required to issue any certificate or certificates for Shares hereunder prior
to fulfillment of all the following conditions: (a) the admission of such Shares to listing on all stock exchanges on which such
class of stock is then listed; (b) the completion of any registration or other qualification of such Shares under any state or
federal law or under the rulings or regulations of the Securities and Exchange Commission or any other governmental regulatory
body, which the Committee shall, in its absolute discretion, deem necessary or advisable; (c) the approval or other clearance from
any state or federal governmental regulatory body, which the Committee shall, in its absolute discretion, determine to be necessary
or advisable; and (d) the lapse of such reasonable period of time following the Settlement Date as the Committee may establish
from time to time for reasons of administrative convenience.

provisions of this Agreement and one or more provisions of the Plan, the provisions of the Plan shall govern.

interpretation and application of the Plan as are consistent therewith and to interpret or revoke any such rules. All actions taken
and all interpretations and determinations made by the Committee in good faith shall be final and binding upon the Employee, the
Company and all other interested persons. No member of the Committee shall be personally liable for any action, determination or
interpretation made in good faith with respect to the Plan or this Agreement. In its absolute discretion, the Board may at any
time and from time to time exercise any and all rights and duties of the Committee under the Plan and this Agreement.

Captions provided herein are for convenience only and are not to serve as a basis for interpretation or construction of this Agreement.

 

21.         Severability.
In the event that any provision in this Agreement shall be held invalid or unenforceable, such provision shall be severable from,
and such invalidity or unenforceability shall not be construed to have any effect on, the remaining provisions of this Agreement.

 

22.         Modifications
to the Agreement. This Agreement constitutes the entire understanding of the parties on the subjects covered. The Employee
expressly warrants that he or she is not executing this Agreement in reliance on any promises, representations, or inducements

of all Performance Units or any other entitlement to Shares awarded, cancelled, vested, unvested or outstanding for the purpose

understands that the Data may be transferred to the Company or any of the Affiliates, or to any third parties assisting in the
implementation, administration and management of the Plan, that these recipients may be located in the Employee’s country
or elsewhere, and that the recipients’ country may have different data privacy laws and protections than the Employee’s
country. The Employee understands that he or she may request a list with the names and addresses of any potential recipients of
the Data by contacting his or her local human resources representative. The Employee authorizes the recipients to receive, possess,
use, retain and transfer the Data, in electronic or other form, for the sole purpose of implementing, administering and managing
his or her participation in the Plan, including any requisite transfer of such Data to a broker or other third party assisting

in the Company’s business expense reimbursement policy.
