	4.	Administration of the Plan 

(a) Procedure. 
 (i) Administration. The Plan will be administered by a committee of the Board that is comprised of directors meeting (i) the “independent director” definition set forth in The
NASDAQ Marketplace Rules applicable to the Company, (ii) the “non-employee director” definition set forth in Rule 16b-3 promulgated under the Exchange Act, and (iii) as appropriate, all other Applicable Laws. 

(ii) Section 162(m). To the extent that the Administrator determines it to be desirable and necessary to qualify Awards
granted hereunder as “performance-based compensation” within the meaning of Section 162(m) of the Code, such Awards will be structured to satisfy such requirements. 

(iii) Rule 16b-3. To the extent that the Administrator determines it to be desirable and necessary to qualify Awards as
exempt under Rule 16b-3 or other securities rule or regulation, the transactions contemplated hereunder will be structured to satisfy such requirements. 
 (iv) Section 409A. To the extent that the Administrator determines it to be desirable and necessary, Awards will be structured and administered (including the terms and conditions of such
Awards as set forth in any applicable Award Agreement) so as to enable such Awards to be exempt under Section 409A of the Code or, to the extent the Award is subject to Section 409A, to comply with the applicable substantive provisions of
Section 409A, and to the extent an Award is intended to be so structured and administered, the terms of the Plan and the Award shall be interpreted to comply with Section 409A. 

  
 5 

 (v) Delegation of Authority for Day-to-Day Administration. Except to the extent
prohibited by Applicable Law, the Administrator may delegate to one or more individuals the day-to-day administration of the Plan and any of the functions assigned to it in this Plan. Such delegation may be revoked at any time. 

(b) Powers of the Administrator. Subject to the provisions of the Plan and the specific duties delegated by the Board, the
Administrator will have the authority, in its discretion: 
 (i) to determine the Fair Market Value; 

(ii) to select the Service Providers to whom Awards may be granted hereunder; 

(iii) to determine the number of Shares to be covered by each Award granted hereunder; 

(iv) to approve forms of Award Agreements for use under the Plan; 

(v) to determine the terms and conditions, not inconsistent with the terms of the Plan, of any Award granted hereunder. Such terms
and conditions include, but are not limited to, the exercise price, the time or times when Awards may be exercised or paid (which may be based on performance criteria), any vesting acceleration or waiver of forfeiture or repurchase restrictions, and
any restriction or limitation regarding any Award or the Shares relating thereto, based in each case on such factors as the Administrator, in its sole discretion, will determine; 

(vi) to construe and interpret the terms of the Plan and Awards granted pursuant to the Plan; 

(vii) to prescribe, amend and rescind rules and regulations relating to the Plan, including rules and regulations relating to
sub-plans established for the purpose of satisfying applicable foreign laws and/or qualifying for preferred tax treatment under applicable foreign tax laws; 
 (viii) to modify or amend each Award (subject to Section 18 ), including the discretionary authority to extend the post-termination exercisability period of Awards longer than is
otherwise provided for in the Plan; 
 (ix) to allow Participants to satisfy withholding tax obligations by electing to
have the Company withhold from the Shares or cash to be issued upon exercise, vesting or payment of an Award that number of Shares or cash having a Fair Market Value equal to the minimum statutory amount required to be withheld. The Fair Market
Value of any Shares to be withheld will be determined on the date that the amount of tax to be withheld is to be determined. All elections by a Participant to have Shares or cash withheld for this purpose will be made in such form and under such
conditions as the Administrator may deem necessary or advisable; 
 (x) to authorize any person to execute on behalf of the
Company any instrument required to implement the grant of an Award previously granted by the Administrator; 
 (xi) to
allow a Participant to defer the receipt of the payment of cash or the delivery of Shares that would otherwise be due to such Participant under an Award; 

  
 6 

 (xii) to determine whether Awards will be settled in Shares, cash or in any combination
thereof; 
 (xiii) to determine whether Awards will be adjusted for Dividend Equivalents; 

(xiv) to create Other Stock Based Awards for issuance under the Plan; 

(xv) to establish a program whereby Service Providers designated by the Administrator can reduce compensation otherwise payable in
cash in exchange for Awards under the Plan;
 (xvi) to impose such restrictions, conditions or limitations as it determines
appropriate as to the timing and manner of any resales by a Participant or other subsequent transfers by the Participant of any Shares issued as a result of or under an Award, including without limitation, (A) restrictions under an insider
trading policy, and (B) restrictions as to the use of a specified brokerage firm for such resales or other transfers; and 

(xvii) to make all other determinations deemed necessary or advisable for administering the Plan. 

(c) Effect of Administrator’s Decision. The Administrator’s decisions, determinations and interpretations will be
final and binding on all Participants and any other holders of Awards. 
 (d) No Repricing or Exchange Program without
Stockholder Approval. Without the prior approval of the Company’s stockholders, no Award issued under the Plan shall be exchanged for another Award in an exchange program nor shall any Option otherwise have its exercise price reduced.

 Except in connection with a corporate transaction involving the company (including, without limitation, any stock dividend,
stock split, extraordinary cash dividend, recapitalization, reorganization, merger, consolidation, split-up, spin-off, combination, or exchange of shares), the terms of outstanding awards may not be amended to reduce the exercise price of
outstanding Options or SARs or cancel outstanding Options or SARS in exchange for cash, other awards or Options or SARs with an exercise price that is less than the exercise price of the original Options or SARs without stockholder approval.

 Repricing of Options or SARs shall not be permitted without stockholder approval. For this purpose, a “repricing”
means any of the following (or any other action that has the same effect as any of the following): (A) changing the terms of an Option or SAR to lower its Exercise Price; (B) any other action that is treated as a “repricing”
under generally accepted accounting principles; and (C) repurchasing for cash or canceling an Option or SAR at a time when its Exercise Price is greater than the Fair Market Value of the underlying stock in exchange for another Award, unless
the cancellation and exchange occurs in connection with an event set forth in Section 12. Such cancellation and exchange would be considered a “repricing” regardless of whether it is treated as a “repricing” under generally
accepted accounting principles and regardless of whether it is voluntary on the part of the Participant. 
  

	5.	Eligibility 

 Nonstatutory
Stock Options, Restricted Stock, Stock Appreciation Rights, Performance Units, Performance Shares, Restricted Stock Units and Other Stock Based Awards may be granted to Service Providers. Incentive Stock Options may be granted only to Employees.

  
 7 

	6.	Limitations 

(a) ISO $100,000 Rule. Each Option will be designated in the Award Agreement as either an Incentive Stock Option or a
Nonstatutory Stock Option. Notwithstanding such designation, to the extent that the aggregate Fair Market Value of the Shares with respect to which Incentive Stock Options are exercisable for the first time by the Participant during any calendar
year (under all plans of the Company and any Parent or Subsidiary) exceeds $100,000, such Options will be treated as Nonstatutory Stock Options. For purposes of this Section 6(a) , Incentive Stock Options will be taken into account in
the order in which they were granted. The Fair Market Value of the Shares will be determined as of the time the Option with respect to such Shares is granted. 
 (b) No Rights as a Service Provider. Neither the Plan nor any Award shall confer upon a Participant any right with respect to continuing his or her relationship as a Service Provider, nor
shall they interfere in any way with the right of the Participant or the right of the Company or its Parent or Subsidiaries to terminate such relationship at any time, with or without cause. 

(c) 162(m) Limitation. The following limitations shall apply to Awards under the Plan: 

(i) Option and SAR Share Annual Limit. No Service Provider will be granted, in any Fiscal Year, Options and/or SARs to
purchase more than 250,000 Shares. 
 (ii) Section 162(m) Performance Restrictions. For purposes of qualifying
grants of Restricted Stock, Restricted Stock Units, Performance Shares or Performance Units as “performance-based compensation” under Section 162(m) of the Code, the Administrator, in its discretion, may set restrictions based upon
the achievement of Performance Goals. The Performance Goals shall be set by the Administrator on or before the latest date permissible to enable the Restricted Stock Units, Restricted Stock, Performance Shares or Performance Units to qualify as
“performance-based compensation” under Section 162(m) of the Code. In granting Restricted Stock Units, Restricted Stock, Performance Shares or Performance Units which are intended to qualify under Section 162(m) of the Code, the
Administrator shall follow any procedures determined by it from time to time to be necessary or appropriate to ensure qualification of the Award under Section 162(m) of the Code (e.g., in determining the Performance Goals).

(iii) The foregoing limitations will be adjusted proportionately in connection with any change in the Company’s capitalization
as described in Section 15. 
 (iv) If an Award is cancelled in the same Fiscal Year in which it was granted
(other than in connection with a transaction described in Section 15), the cancelled Award will be counted against the limits set forth in subsections (i) and (ii) above. For this purpose, if the exercise price of an Option is
reduced, the transaction will be treated as a cancellation of the Option and the grant of a new Option. 
  

	7.	Stock Options 

(a) Term of Option. The term of each Option will be ten years from the date of grant or such shorter term as may be provided
in the Award Agreement. Moreover, in the case of an Incentive Stock Option granted to a Participant who, at the time the Incentive Stock Option is granted, owns stock representing more than ten percent of the total combined voting power of all
classes of stock of the Company or any Parent or Subsidiary, the term of the Incentive Stock Option will be five years from the date of grant or such shorter term as may be provided in the Award Agreement. 

  
 8 

 (b) Option Exercise Price and Consideration. 

(i) Exercise Price. The per Share exercise price for the Shares to be issued pursuant to exercise of an Option will be
determined by the Administrator, subject to the following: 
 (1) In the case of an Incentive Stock Option 

(A) granted to an Employee who, at the time the Incentive Stock Option is granted, owns stock representing more than ten percent of
the voting power of all classes of stock of the Company or any Parent or Subsidiary, the per Share exercise price will be no less than 110% of the Fair Market Value per Share on the date of grant. 

(B) granted to any Employee other than an Employee described in paragraph (A) immediately above, the per Share exercise price
will be no less than 100% of the Fair Market Value per Share on the date of grant. 
 (2) In the case of a Nonstatutory
Stock Option, the per Share exercise price will be determined by the Administrator. In the case of a Nonstatutory Stock Option intended to qualify as “performance-based compensation” within the meaning of Section 162(m) of the Code or
for the exemption from treatment as deferred compensation under Section 409A of the Code, the per Share exercise price will be no less than 100% of the Fair Market Value per Share on the date of grant. 

(ii) Waiting Period, Vesting, Exercise Dates. At the time an Option is granted, the Administrator will fix the period within
which the Option may be exercised and will determine any conditions, including the vesting schedule, that must be satisfied before the Option may be exercised. Any Option granted to a Participant who is not a Director or Consultant shall vest
ratably as determined by the Administrator over a period of at least three years. Any Option granted to a Participant who is a Director or Consultant shall vest ratably as determined by the Administrator over a period of at least one year.
Notwithstanding the foregoing vesting periods, the Administrator may in its discretion grant Options with a vesting schedule that is less than the applicable period set forth above, or shorten the vesting schedule of an outstanding Option to a
period less than the applicable period set forth above, when such Options are granted to a Participant in connection with his or her commencement of service with the Company or any Affiliate of the Company or are granted to a Participant who
retires, dies or becomes disabled due to a Disability while in service with the Company or any Affiliate of the Company, or in connection with other situations not in the ordinary course of business.

(c) Form of Consideration. The Administrator will determine the acceptable form of consideration for exercising an Option,
including the method of payment. In the case of an Incentive Stock Option, the Administrator will determine the acceptable form of consideration at the time of grant. Such consideration to the extent permitted by Applicable Laws may consist entirely
of: 
 (i) cash; 
 (ii) check; 

  
 9 

 (iii) other Shares which meet the conditions established by the Administrator to avoid
adverse accounting consequences (as determined by the Administrator); 
 (iv) consideration received by the Company under a
cashless exercise program implemented by the Company in connection with the Plan; 
 (v) any combination of the foregoing
methods of payment; or 
 (vi) such other consideration and method of payment for the issuance of Shares to the extent
permitted by Applicable Laws. 
 (d) Exercise of Option. 

(i) Procedure for Exercise; Rights as a Stockholder. Any Option granted hereunder will be exercisable according to the terms
of the Plan and at such times and under such conditions as determined by the Administrator and set forth in the Award Agreement. An Option may not be exercised for a fraction of a Share. An Option will be deemed exercised when the Company receives:
(A) written or electronic notice of exercise (in accordance with the Award Agreement) from the person entitled to exercise the Option, and (B) full payment for the Shares with respect to which the Option is exercised. Full payment may
consist of any consideration and method of payment authorized by the Administrator and permitted by the Award Agreement and the Plan. Shares issued upon exercise of an Option will be issued in the name of the Participant or, if requested by the
Participant, in the name of the Participant and his or her spouse. Until the Shares are issued (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company), no right to vote or receive
dividends or any other rights as a stockholder will exist with respect to the Awarded Stock, notwithstanding the exercise of the Option. The Company will issue (or cause to be issued) such Shares promptly after the Option is exercised. No adjustment
will be made for a dividend or other right for which the Record Date is prior to the date the Shares are issued, except as provided in Section 15 of the Plan or the applicable Award Agreement. Exercising an Option in any manner will
decrease the number of Shares thereafter available for sale under the Option, by the number of Shares as to which the Option is exercised. 
 (ii) Termination of Relationship as a Service Provider. If a Participant ceases to be a Service Provider, other than upon the Participant’s death or Disability, the Participant may
exercise his or her Option within such period of time as is specified in the Award Agreement to the extent that the Option is vested on the date of termination (but in no event later than the expiration of the term of such Option as set forth in the
Award Agreement). In the absence of a specified time in the Award Agreement, the Option will remain exercisable for three months following the Participant’s termination. Unless otherwise provided by the Administrator, if on the date of
termination the Participant is not vested as to his or her entire Option, the Shares covered by the unvested portion of the Option will revert to the Plan following the Participant’s termination. If after termination the Participant does not
exercise his or her Option within the time specified by the Administrator, the Option will terminate, and the Shares covered by such Option will revert to the Plan. 

  
 10 

 (iii) Disability of Participant. If a Participant ceases to be a Service
Provider as a result of the Participant’s Disability, the Participant may exercise his or her Option within such period of time as is specified in the Award Agreement to the extent the Option is vested on the date of termination (but in no
event later than the expiration of the term of such Option as set forth in the Award Agreement). In the absence of a specified time in the Award Agreement, the Option will remain exercisable for twelve months following the Participant’s
termination. Unless otherwise provided by the Administrator, if on the date of termination the Participant is not vested as to his or her entire Option, the Shares covered by the unvested portion of the Option will revert to the Plan following the
Participant’s termination. If after termination the Participant does not exercise his or her Option within the time specified herein, the Option will terminate, and the Shares covered by such Option will revert to the Plan. 

(iv) Death of Participant. If a Participant dies while a Service Provider, the Option may be exercised following the
Participant’s death within such period of time as is specified in the Award Agreement to the extent that the Option is vested on the date of death (but in no event may the Option be exercised later than the expiration of the term of such Option
as set forth in the Award Agreement), by the Participant’s designated beneficiary, provided such beneficiary has been designated prior to Participant’s death in a form acceptable to the Administrator. If no such beneficiary has been
designated by the Participant, then such Option may be exercised by the personal representative of the Participant’s estate or by the person(s) to whom the Option is transferred pursuant to the Participant’s will or in accordance with the
laws of descent and distribution. In the absence of a specified time in the Award Agreement, the Option will remain exercisable for twelve months following Participant’s death. If the Option is not so exercised within the time specified herein,
the Option will terminate, and the Shares covered by such Option will revert to the Plan. 
  

	8.	Restricted Stock 

(a) Grant of Restricted Stock. Subject to the terms and provisions of the Plan, the Administrator, at any time and from time
to time, may grant Shares of Restricted Stock to Service Providers in such amounts as the Administrator, in its sole discretion, will determine. Subject to Section 6(c)(ii) hereof, the Administrator shall have complete discretion to
determine (i) the number of Shares subject to a Restricted Stock award granted to any Participant, and (ii) the conditions that must be satisfied, which typically will be based principally or solely on continued provision of services but
may include a performance-based component, upon which is conditioned the grant, vesting or issuance of Restricted Stock. Notwithstanding the preceding sentence, (i) any Restricted Stock granted to a Participant who is not a Director or
Consultant shall vest ratably as determined by the Administrator over a period of at least three years, and (ii) any Restricted Stock granted to a Director or Consultant shall vest ratably as determined by the Administrator over a period of at
least one year. Notwithstanding the foregoing vesting periods, the Administrator may in its discretion grant Restricted Stock with a vesting schedule that is less than the applicable period set forth above, or shorten the vesting schedule of
outstanding Restricted Stock to a period less than the applicable period set forth above, when such Restricted Stock is granted to a Participant in connection with his or her commencement of service with the Company or any Affiliate of the Company
or is granted to a Participant who retires, dies or becomes disabled due to a Disability while in service with the Company or any Affiliate of the Company, or in connection with other situations not in the ordinary course of business. 

  
 11 

 (b) Restricted Stock Agreement. Each Award of Restricted Stock will be evidenced
by an Award Agreement that will specify the Period of Restriction, the number of Shares granted, and such other terms and conditions as the Administrator, in its sole discretion, will determine. Unless the Administrator determines otherwise, Shares
of Restricted Stock will be held by the Company as escrow agent until the restrictions on such Shares have lapsed.

(c) Transferability. Except as provided in this Section 8, Shares of Restricted Stock may not be sold,
transferred, pledged, assigned, or otherwise alienated or hypothecated until the end of the applicable Period of Restriction. 

(d) Other Restrictions. The Administrator, in its sole discretion, may impose such other restrictions on Shares of Restricted
Stock as it may deem advisable or appropriate. 
 (e) Removal of Restrictions. Except as otherwise provided in this
Section 8, Shares of Restricted Stock covered by each Restricted Stock grant made under the Plan will be released from escrow as soon as practicable after the last day of the Period of Restriction.

will be entitled to receive all dividends and other distributions paid with respect to such Shares unless otherwise provided in the Award Agreement. If any such dividends or distributions are paid in Shares, the Shares will be subject to the same
restrictions on transferability and forfeitability as the Shares of Restricted Stock with respect to which they were paid. 

(h) Return of Restricted Stock to Company. On the date set forth in the Award Agreement, the Restricted Stock for which
restrictions have not lapsed will revert to the Company and again will become available for grant under the Plan.

Subject to Section 6(c)(i) of the Plan, the Administrator will have complete discretion to determine the number of SARs granted to any Service Provider. 
 (c) Exercise Price and Other Terms. The Administrator, subject to the provisions of the Plan, will have complete discretion to determine the terms and conditions of SARs granted under the

Affiliate of the Company or are granted to a Participant who retires, dies or becomes disabled due to a Disability while in service with the Company or any Affiliate of the Company, or in connection with other situations not in the ordinary course

conditions as the Administrator, in its sole discretion, will determine. 
 (f) Expiration of SARs. An SAR granted
under the Plan will expire upon the date determined by the Administrator, in its sole discretion, and set forth in the Award Agreement. Notwithstanding the foregoing, the rules of Sections 7(d)(ii) , 7(d)(iii) and 7(d)(iv)

receive payment from the Company in an amount determined by multiplying: 
 (i) The difference between the Fair Market
Value of a Share on the date of exercise over the exercise price; times

the SAR is exercised. 
 At the discretion of the Administrator, the payment upon SAR exercise may be in cash, in Shares of equivalent value, or
in some combination thereof. 
  

	10.	Performance Units and Performance Shares 

 (a) Grant of Performance Units/Shares. Subject to the terms and conditions of the Plan, Performance Units and Performance Shares may be granted to Service Providers at any time and from time
to time, as will be determined by the Administrator, in its sole discretion. Subject to Section 6(c)(ii) , the Administrator will have complete discretion in determining the number of Performance Units and Performance Shares granted to
each Participant. 
 (b) Value of Performance Units/Shares. Each Performance Unit will have an initial value that is
established by the Administrator on or before the date of grant. Each Performance Share will have an initial value equal to the Fair Market Value of a Share on the date of grant. 

(c) Performance Objectives and Other Terms. The Administrator will set Performance Goals in its discretion which, depending
on the extent to which they are met, will determine the number or value of Performance Units/Shares that will be paid out to the Service Providers. The time period during which the performance objectives must be met will be called the
“Performance Period.” The Performance Period shall be such period as determined by the Administrator, which period shall not be less than one year, provided that, the Administrator may in its discretion provide a Performance Period of less
than one year, or shorten the Performance Period, when the Performance Units or Performance Shares are granted to a Participant in connection with his or her commencement of service with the Company or any Affiliate of the Company or are granted to
a Participant who retires, dies or becomes disabled due to a Disability while in service with the Company or any Affiliate of the Company, or in connection with other situations not in the ordinary course of business. Each Award of Performance
Units/Shares will be evidenced by an Award Agreement that will specify the Performance Period, and such other terms and conditions as the Administrator, in its sole discretion, will determine. The Administrator may set Performance Goals based upon
the achievement of Company-wide, divisional, or individual goals, applicable federal or state securities laws, or any other basis determined by the Administrator in its discretion. 

  
 13 

 (d) Earning of Performance Units/Shares. After the applicable Performance Period
has ended, the holder of Performance Units/Shares will be entitled to receive a payout of the number of Performance Units/Shares earned by the Participant over the Performance Period, to be determined as a function of the extent to which the
corresponding Performance Goals have been achieved. 
 (e) Form and Timing of Payment of Performance Units/Shares.
Payment of earned Performance Units/Shares will be made as soon after the expiration of the applicable Performance Period as determined by the Administrator. The Administrator, in its sole discretion, may pay earned Performance Units/Shares in the
form of cash, in Shares (which have an aggregate Fair Market Value equal to the value of the earned Performance Units/Shares at the close of the applicable Performance Period) or in a combination thereof. 

(f) Cancellation of Performance Units/Shares. On the date set forth in the Award Agreement, all unearned or unvested
Performance Units/Shares will be forfeited to the Company, and again will be available for grant under the Plan. 
  

	11.	Restricted Stock Units 

Restricted Stock Units shall consist of a Restricted Stock, Performance Share or Performance Unit Award that the Administrator, in its
sole discretion permits to be paid out in installments or on a deferred basis, in accordance with rules and procedures established by the Administrator. Restricted Stock Units will be subject to such terms and conditions (including but not limited
to those relating to vesting, performance goals and performance periods) as determined by the Administrator, subject to such rules and limitations as are consistent with, as applicable, the provisions of the Plan applicable to Restricted Stock,
Performance Units and Performance Shares. 
  

	12.	Other Stock Based Awards 

Other Stock Based Awards may be granted separately, in addition to, or in lieu of other Awards granted under the Plan or cash awards made
outside of the Plan. The Administrator shall have authority to determine the Service Providers to whom and the time or times at which Other Stock Based Awards shall be made, the amount of such Other Stock Based Awards, and all other conditions of
the Other Stock Based Awards including any dividend and/or voting rights. Any Other Stock Based Award pursuant to which vesting, settlement, exercise or payment is based on completion of a prescribed service period or passage of time and
(i) which is granted to a Participant who is not a Director or Consultant shall vest ratably as determined by the Administrator over a period of at least three years or (ii) which is granted to a Director or Consultant shall vest ratably
as determined by the Administrator over a period of at least one year. Notwithstanding the foregoing, the Administrator may in its discretion grant Other Stock Based Awards with a vesting, settlement, exercise or payment schedule that is less than
the applicable period set forth above, or shorten the vesting, settlement, exercise or payment schedule of an outstanding Other Stock Based Award, when such awards are granted to Participant in connection with his or her commencement of service with
the Company or any Affiliate of the Company or are granted to a Participant who retires, dies or becomes disabled due to a Disability while in service with the Company or any Affiliate of the Company, or in connection with other situations not in
the ordinary course of business. In the case of an Other Stock Based Award that vests, is settled or paid or is exercisable upon the attainment of performance goals, the performance period applicable to such Award shall not be less than one year,
provided that, a performance period of less than one year may apply as determined by the Administrator when the award is granted to a Participant in connection with his or her commencement of service with the Company or any Affiliate of the Company
or is granted to a Participant who retires, dies or becomes disabled due to a Disability while in service with the Company or any Affiliate of the Company, or in connection with other situations not in the ordinary course of business. 

  
 14 

	13.	Leaves of Absence 

 Unless
the Administrator provides otherwise, vesting of Awards granted hereunder will continue during any authorized leave of absence provided such leave does not exceed 90 days. If the leave of absence exceeds 90 days, vesting of Awards shall
continue as determined by the Administrator. A Service Provider will not cease to be an Employee in the case of (a) any leave of absence approved by the Company or (b) transfers between locations of the Company or between the Company, its
Parent, or any Subsidiary. For purposes of Incentive Stock Options, no such leave may exceed 90 days, unless reemployment upon expiration of such leave is guaranteed by statute or contract. If reemployment upon expiration of a leave of absence
approved by the Company is not so guaranteed, then three months following the 91 st day of such leave any Incentive Stock Option held by the Participant will cease to be treated as an Incentive Stock Option and will be treated for tax purposes as a
Nonstatutory Stock Option. 
  

	14.	Non-Transferability of Awards 

 An Award may not be sold, pledged, assigned, hypothecated, transferred, or disposed of in any manner other than by will or by the laws of descent or distribution and may be exercised, during the lifetime
of the Participant, only by the Participant. 
  

	15.	Adjustments; Dissolution or Liquidation; Change in Control 

 (a) Adjustments. In the event that any dividend (excluding an ordinary dividend) or other distribution (whether in the form of cash, Shares, other securities, or other property),
recapitalization, stock split, reverse stock split, reorganization, merger, consolidation, split-up, spin-off, combination, repurchase, or exchange of Shares or other securities of the Company, or other change in the corporate structure of the
Company affecting the Shares occurs, then the Administrator shall appropriately adjust (consistent, as applicable, with Code Sections 422 and 424) the number and class of Shares which may be delivered under the Plan, the Code Section 162(m)
annual share issuance limits under Section 6(c) of the Plan, and the number, class, and price of Shares subject to outstanding Awards. Notwithstanding the preceding, the number of Shares subject to any Award always shall be a whole
number. 

  
 15 

 (b) Dissolution or Liquidation. In the event of the proposed dissolution or
liquidation of the Company, the Administrator will notify each Participant as soon as practicable prior to the effective date of such proposed transaction. The Administrator in its discretion may provide for a Participant to have the right to
exercise his or her Award, to the extent applicable, until ten days prior to such transaction as to all of the Awarded Stock covered thereby, including Shares as to which the Award would not otherwise be exercisable. In addition, the Administrator
may provide that any Company repurchase option or forfeiture rights applicable to any Award shall lapse 100%, and that any Award vesting shall accelerate 100%, provided the proposed dissolution or liquidation takes place at the time and in the
manner contemplated. To the extent it has not been previously exercised or vested, an Award will terminate immediately prior to the consummation of such proposed action. 
 (c) Change in Control. In the event of a Change in Control, the Administrator in its discretion may, at the time an Award is made or at any time thereafter, take one or more of the following
actions: (i) provide for the acceleration of any time period relating to the exercise or realization of the Award, (ii) provide for the purchase of the Award upon the Participant’s request for an amount of cash or other property that
could have been received upon the exercise or realization of the Award had the Award been currently exercisable or payable, (iii) adjust the terms of the Award in a manner determined by the Administrator to reflect the Change in Control,
(iv) cause the Award to be assumed, or new rights substituted therefore, by another entity, or (v) make such other provision as the Administrator may consider equitable and in the best interests of the Company. Notwithstanding the
foregoing, any change in Incentive Stock Options shall comply with the rules under Section 424 of the Code and no change may be made to any Award which would make the Award subject to the provisions of Section 409A of the Code. 

 

	16.	Date of Grant 

 The date
of grant of an Award will be, for all purposes, the date on which the Administrator makes the determination granting such Award, or such other later date as is determined by the Administrator. Notice of the determination will be provided to each
Participant within a reasonable time after the date of such grant. 
  

	17.	Term of Plan 

 Subject to
Section 22 of the Plan, the Plan will become effective upon its adoption by the Board. It will continue in effect for a term of ten years unless terminated earlier under Section 18 of the Plan. 

 

	18.	Amendment and Termination of the Plan 

 (a) Amendment and Termination. The Board may at any time amend, alter, suspend or terminate the Plan; provided that any material amendment to the Plan shall require shareholder approval in
accordance with Rule 4350(i)(1)(A) of The NASDAQ Marketplace Rules applicable to the Company. 
 (b) Effect of
Amendment or Termination. Subject to Section 20 of the Plan, no amendment, alteration, suspension or termination of the Plan will materially impair the vested rights of any Participant with respect to any outstanding Award, unless
mutually agreed otherwise between the Participant and the Administrator, which agreement must be in writing and signed by the Participant and the Company, or except as may otherwise be necessary or advisable in order to comply with the requirements
of Code Section 409A. Termination of the Plan will not affect the Administrator’s ability to exercise the powers granted to it hereunder with respect to Awards granted under the Plan prior to the date of such termination. 

  
 16 

	19.	Conditions Upon Issuance of Shares 

 (a) Legal Compliance. Shares will not be issued pursuant to the exercise of an Award unless the exercise of such Award and the issuance and delivery of such Shares will comply with Applicable
Laws and will be further subject to the approval of counsel for the Company with respect to such compliance. 

(b) Investment Representations. As a condition to the exercise or receipt of an Award, the Company may require the person
exercising or receiving such Award to represent and warrant at the time of any such exercise or receipt that the Shares are being purchased only for investment and without any present intention to sell or distribute such Shares if, in the opinion of
counsel for the Company, such a representation is required. 
  

	20.	Severability 

Notwithstanding any contrary provision of the Plan or an Award to the contrary, if any one or more of the provisions (or any part thereof)
of this Plan or the Awards shall be held invalid, illegal or unenforceable in any respect, such provision shall be modified so as to make it valid, legal and enforceable in a manner to the greatest extent possible to conform with the original intent
of such provision, and the validity, legality and enforceability of the remaining provisions (or any part thereof) of the Plan or Award, as applicable, shall not in any way be affected or impaired thereby. 

 

	21.	Inability to Obtain Authority 

 The inability of the Company to obtain authority from any regulatory body having jurisdiction, which authority is deemed by the Company’s counsel to be necessary to the lawful issuance and sale of
any Shares hereunder, will relieve the Company of any liability in respect of the failure to issue or sell such Shares as to which such requisite authority will not have been obtained. 

 

	22.	Stockholder Approval 

 The
Plan will be subject to approval by the stockholders of the Company within twelve months after the date the Plan is adopted. Such stockholder approval will be obtained in the manner and to the degree required under Applicable Laws. 

Adopted by stockholders March 25, 2010. Amended by stockholders April 5, 2012 and further amended by the Board of Directors on June 14, 2012.

sum of two hundred and fifty million Dollars on June 1, 2042, at the office or agency of the Company in the Borough of Manhattan, The City of New York, in such coin or currency of the United States of America as at the time of payment shall be
legal tender for public and private debts, and to pay interest thereon, semi-annually on June 1 and December 1 of each year at the rate of four percent (4.00%) per annum, at said office or agency in like coin or currency, from the
first day of June or December, as the case may be, to which interest has been paid preceding the date hereof (unless the date hereof is a June 1 or December 1 on which interest has been paid, in which case from the date hereof, or unless
the date hereof is prior to December 1, 2012, in which case from June 26, 2012), until this bond shall mature, according to its terms or on prior redemption or by declaration or otherwise, and at the highest rate of interest borne by any

 [FORM OF REVERSE OF BOND] 
 DELMARVA POWER & LIGHT COMPANY 
 FIRST MORTGAGE BOND,

 4.00% SERIES DUE JUNE 1, 2042 
 This bond is one of an issue of bonds of the Company (herein referred to as the “bonds”), not limited in principal amount, issuable in series, which different series may mature at different
times, may bear interest at different rates, and may otherwise vary as in the Mortgage hereinafter mentioned, and is one of a series known as its First Mortgage Bonds, 4.00% Series due June 1, 2042 (herein sometimes referred to as “bonds
of 4.00% Series”). All bonds of all series and tranches issued and to be issued under and equally and ratably secured (except insofar as any sinking fund, established in accordance with the provisions of the Mortgage hereinafter mentioned, may
afford additional security for the bonds of any particular series or tranche) by the Mortgage and Deed of Trust, dated as of October 1, 1943, executed by the Company to THE NEW YORK TRUST COMPANY, as Trustee, to which THE BANK OF NEW YORK
MELLON, a New York banking corporation, is successor Trustee (herein, together with any indentures supplemental thereto, including a One Hundred and Tenth Supplemental Indenture, dated as of June 19, 2012 (the “One Hundred and Tenth
Supplemental Indenture”), called the “Mortgage”), to which reference is made for a description of the property mortgaged and pledged, the nature and extent of the security, the rights and limitations of rights of the holders of the
bonds and of the Company in respect thereof, the rights, duties and immunities of the Trustee, and the terms and conditions upon which the bonds are, and are to be, issued and secured. The Mortgage contains provisions permitting the Company and the
Trustee, with the consent of the holders of not less than seventy-five percent (75%) in principal amount of all the bonds at the time outstanding (determined as provided in the Mortgage), evidenced as in the Mortgage provided, or in case the
rights under the Mortgage of the holder of the bonds of one or more, but less than all, of the series of bonds outstanding shall be affected, then with the consent of the holders of not less than seventy-five percent (75%) in principal amount
of the bonds at the time outstanding of the one or more series, taken in the aggregate, affected (determined as provided in the Mortgage), evidenced as in the Mortgage provided, to execute supplemental indentures adding any provisions to or changing
in any manner or eliminating any of the provisions of the Mortgage or modifying in any manner the rights of the holders of the bonds and coupons; provided, however, that no such supplemental indenture shall (i) extend the fixed maturity of any
bonds, or reduce the rate or extend the time of payment of interest thereon, or reduce the principal amount thereof, without the consent of the holder of each bond so affected, or (ii) reduce the aforesaid percentage of bonds, the holders of
which are required to consent to any such supplemental indenture without the consent of the holders of all bonds then outstanding. Any such consent by the registered holder of this bond (unless effectively revoked as provided in the Mortgage) shall
be conclusive and binding upon such holder and upon all future holders of this bond, irrespective of whether or not any notation of such consent is made upon this bond. No reference herein to the Mortgage and no provision of this bond or of the
Mortgage shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of, premium, if any, and interest on this bond at the time and place, at the rate and in the coin or currency herein prescribed.

  
 4 

 The fully registered bonds of 4.00% Series are issuable in denominations of $1,000 and any
integral multiple thereof. At the office or agency to be maintained by the Company in the Borough of Manhattan, The City of New York and in the manner and subject to the limitations provided in the Mortgage, fully registered bonds of such series may
be exchanged for a like aggregate principal amount of fully registered bonds of such series of other authorized denominations, and in each case without payment of any service or other similar charge, but the Company may require payment of a sum
sufficient to cover any tax or taxes or other governmental charges required to be paid by the Company in relation thereto, as provided in the One Hundred and Tenth Supplemental Indenture. 

The bonds of 4.00% Series shall be redeemable at the option of the Company prior to the express date of the maturity hereof, in whole or
in part, at any time. The Company shall give notice of its intent to redeem such bonds of 4.00% Series at least 30 days but no more than 90 days prior to the date fixed for such redemption (the “Redemption Date”). If the Company redeems
all or any part of the bonds of 4.00% Series pursuant to the provisions of this paragraph prior to December 1, 2041, it shall pay an amount equal to the greater of: 

(i) 100% of the principal amount of the bonds of 4.00% Series being redeemed, and 

(ii) the sum of the present values of the remaining scheduled payments of principal of and interest (not including the
portion of any scheduled payment of interest which accrued prior to the Redemption Date) on the bonds of 4.00% Series being redeemed, discounted to the Redemption Date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day
months) at the Treasury Rate plus 20 basis points, 
 plus, in each case, accrued interest on those bonds to the Redemption Date
(calculated assuming a 360-day year consisting of twelve 30-day months and for any period shorter than a full month, on the basis of the actual number of days elapsed in such period). If the Company redeems all or any part of the bonds of 4.00%
Series pursuant to the provisions of this paragraph on or after December 1, 2041, it shall pay an amount equal to 100% of the principal amount of the bonds of 4.00% Series being redeemed plus accrued and unpaid interest thereupon. 

“Comparable Treasury Issue” means the United States Treasury security selected by an Independent Investment Banker as having a
maturity comparable to the remaining term of the bonds of 4.00% Series to be redeemed that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of
comparable maturity to the remaining term of the bonds of 4.00% Series. 
 “Comparable Treasury Price” means, with
respect to any Redemption Date prior to December 1, 2041, (i) the average of the Reference Treasury Dealer Quotations for such Redemption Date, after excluding the highest and lowest of such Reference Treasury Dealer Quotations or
(ii) if the Company obtains fewer than four of such Reference Treasury Dealer Quotations, the average of all such quotations. 
 “Independent Investment Banker” means an investment banking institution of national standing appointed by the Company that is not the Reference Treasury Dealer. 

“Reference Treasury Dealer” means a primary United States Treasury securities dealer appointed by the Company. 

“Reference Treasury Dealer Quotation” means, with respect to any Redemption Date prior to December 1, 2041, the average,
as determined by the Trustee, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Trustee by such Reference Treasury Dealer at 5:00 p.m. on the third
business day preceding such Redemption Date. 
 “Treasury Rate” means, with respect to any Redemption Date prior to
December 1, 2041, the rate per annum equal to the semi-annual equivalent yield to maturity of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the
Comparable Treasury Price for such Redemption Date. 

  
 5 

 The Company shall deliver to the Trustee before any Redemption Date for the bonds of 4.00%
Series its calculation of the amount applicable to such redemption. Except with respect to the obligations of the Trustee expressly set forth in the foregoing definition of “Reference Treasury Dealer Quotations,” the Trustee shall be under
no duty to inquire into, may presume the correctness of, and shall be fully protected in acting upon, the Company’s calculation of any Redemption Price of the bonds of 4.00% Series. 

In lieu of stating the amount applicable to such redemption, notices of redemption of the bonds of 4.00% Series for a Redemption Date
prior to December 1, 2041 shall state substantially the following: “The amount applicable to the bonds of 4.00% Series to be redeemed shall equal the sum of (a) the greater of (i) 100% of the principal amount of such bonds of
4.00% Series, and (ii) the sum of the present values of the remaining scheduled payments of principal and interest (not including the portion of any scheduled payment of interest which accrued prior to the Redemption Date) on the bonds of 4.00%
Series being redeemed, discounted to the Redemption Date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate (as defined in the bonds of 4.00% Series) plus 20 basis points, plus, in each case,
(b) accrued interest on the principal amount hereof to the Redemption Date.” 
 If at the time notice of redemption is
given the redemption moneys are not on deposit with the Trustee, then the redemption shall be subject to the receipt of such moneys on or before the Redemption Date, and such notice shall be of no effect unless such moneys are received. The Mortgage
provides that if the Company shall deposit with the Trustee in trust for the purpose funds sufficient to pay the principal of all of the bonds of any series, or such of the bonds of any series as have been or are to be called for redemption, and
premium, if any, thereon, and all interest payable on such bonds to the date on which they become due and payable at maturity or upon redemption or otherwise, and shall comply with the other provisions of the Mortgage in respect thereof, then from
the date of such deposit such bonds shall no longer be entitled to any lien or benefit under the Mortgage. 
 The principal
hereof may be declared or may become due prior to the express date of the maturity hereof on the conditions, in the manner and at the time set forth in the Mortgage, upon the occurrence of a completed default as in the Mortgage provided. 

This bond is transferable as prescribed in the Mortgage by the registered holder hereof in person, or by his or her duly authorized
attorney, at the office or agency to be maintained by the Company in the Borough of Manhattan, The City of New York, upon surrender and cancellation of this bond, and thereupon a new fully registered bond or bonds of authorized denominations of the
same series and for the same aggregate principal amount will be issued to the transferee in exchange herefor as provided in the Mortgage, and in each case without payment of any service or other similar charge as provided in the One Hundred and
Tenth Supplemental Indenture. The Company and the Trustee, any paying agent and any bond registrar may deem and treat the person in whose name this bond is registered as the absolute owner hereof, whether or not this bond shall be overdue, for the
purpose of receiving payment and for all other purposes and neither the Company nor the Trustee nor any paying agent nor any bond registrar shall be affected by any notice to the contrary. 

No recourse shall be had for the payment of the principal of, premium, if any, and interest on, this bond, or for any claim based hereon,
or otherwise in respect hereof, or based on, or in respect of, the Mortgage, against an incorporator or any past, present or future subscriber to the capital stock, stockholder, officer or director, as such, of the Company or of any successor
corporation, either directly or through the Company or any successor corporation, under any rule of law, statute or constitution or by the enforcement of any assessment or otherwise, all such liability of incorporators, subscribers, stockholders,
officers and directors, as such, being waived and released by the holder and owner hereof by the acceptance of this bond and being likewise waived and released by the terms of the Mortgage.

 WHEREAS, all acts and things prescribed by law and by the charter and by-laws of the Company
necessary to make the 4.00% Series Bonds, when executed by the Company and authenticated by the Trustee, as in the Original Indenture provided, valid, binding and legal obligations of the Company, entitled in all respects to the security of the

of the Original Indenture any property acquired after the date of the Original Indenture and intended to be covered thereby, with the same force and effect as though included in the granting clause thereof, and to add such further covenants,
restrictions or conditions for the protection of the mortgaged and pledged property and the holders of the bonds as the Board of Directors of the Company and the Trustee shall consider to be for the protection of the holders of the bonds, and to set

heretofore specifically subjected to the lien of the Original Indenture; and it is desired to add certain further covenants, restrictions and conditions for the protection of the mortgaged and pledged property and the holders of the bonds, as
provided in this One Hundred and Tenth Supplemental Indenture, which the Board of Directors of the Company and the Trustee consider to be for the protection of the holders of the bonds; and the Company desires to issue the 4.00% Series Bonds; and

observance of all the covenants and conditions in said bonds and the Original Indenture and any indentures supplemental thereto, including this One Hundred and Tenth Supplemental Indenture, contained and to subject to the lien of the Original
Indenture, as so supplemented, with the same force and effect as though included in the granting clause thereof, and in consideration of the premises and of the sum of One Dollar ($1.00), lawful money of the United States of America, to the Company
duly paid by the Trustee at or before the ensealing and delivery hereof, and other valuable consideration, the receipt whereof is hereby acknowledged, and intending to be legally bound hereby, the Company has executed and delivered this One Hundred

release, convey, assign, transfer, mortgage, pledge, set over and confirm, and grant a security interest therein, subject to the provisions of the Indenture, unto THE BANK OF NEW YORK MELLON, as trustee, and to its successors in trust and to its and
their assigns forever, all the following described properties of the Company, and does hereby confirm that the Company will not cause or consent to a partition, either voluntary or through legal proceedings, of property, whether herein described or

 Together with all and singular the tenements, hereditaments and appurtenances belonging or in any

Provided that, in addition to the reservations and exceptions herein and elsewhere contained, the following are not and are not intended

operation of the Original Indenture and any indentures supplemental thereto, including this One Hundred and Tenth Supplemental Indenture, viz.: (1) cash and shares of stock and certificates

specifically pledged or deposited or delivered or therein covenanted so to be; (2) any goods, wares, merchandise, equipment, materials or supplies held or acquired for the purpose of sale or resale in the usual course of business or for

any of the property embraced herein; 
 IN TRUST NEVERTHELESS upon the terms, trusts, uses and purposes specifically set forth
in the Indenture; this One Hundred and Tenth Supplemental Indenture being made for the purpose, inter alia, of subjecting the real estate and premises and other property above described to the lien and operation of the Indenture, so that the same
shall be held specifically by the Trustee under and subject to the terms and conditions of the Original Indenture in identically the same manner and for the same trusts, uses and purposes, as though the said real estate and premises and other
property had been specifically described in the Original Indenture. 
 AND IT IS HEREBY FURTHER COVENANTED AND AGREED and the
Company and the Trustee have mutually agreed, in consideration of the premises, as follows: 
 ARTICLE I. 

DESIGNATION, PROVISIONS, DENOMINATIONS AND ISSUANCE 
 OF 4.00% SERIES BONDS 
 SECTION 1. The bonds of 4.00% Series shall be designated
as “First Mortgage Bonds, 4.00% Series due June 1, 2042.” The bonds of 4.00% Series shall be issuable from time to time as fully registered bonds in denominations of $1,000 and in any integral multiple thereof. Each of the bonds of
4.00% Series shall be dated the date of issue, and shall bear interest payable from the first day of June or December, as the case may be, to which interest has been paid preceding the date thereof, unless such date is a June 1 or
December 1 on which interest has been paid, in which case it shall bear interest from such date, or unless such date is prior to December 1, 2012, in which case it shall bear interest from June 26, 2012. The interest so payable on any
June 1 or December 1 will be paid to the person in whose name this Bond is registered at the close of business on the fifteenth calendar day of the month preceding the month in which the interest payment date occurs. All bonds of 4.00%
Series shall be payable on June 1, 2042, in such coin or currency of the United States of America as at 

  
 9 

 
the time of payment shall be legal tender for public and private debts, and shall bear interest, payable in like coin and currency, at the rate of four percent (4.00%) per annum, payable
semi-annually on June 1 and December 1 of each year, until maturity, and at the highest rate of interest borne by any of the bonds outstanding under the Original Indenture and any indenture supplemental thereto, from such date of maturity
until they shall be paid or payment thereof shall have been duly provided for; provided, however, that interest payable at maturity will be paid to the person to whom principal is paid. In the event that any interest payment date is a legal holiday
or a day on which banking institutions are authorized by law to close, then payment of interest payable on such date may be made on the next succeeding day, not a legal holiday or a day on which banking institutions are authorized by law to close,
with the same force and effect as if made on the interest payment date. Interest on the bonds of 4.00% Series shall be computed on the basis of a 360-day year consisting of twelve 30-day months. The principal of, and premium, if any, and interest
on, each bond of 4.00% Series shall be payable at the office or agency of the Company in the Borough of Manhattan, The City of New York. 
 The bonds of 4.00% Series may be exchanged, for a like aggregate principal amount of fully registered bonds of such series of other authorized denominations. No service or other similar charge shall be
made for any exchange, transfer, or registration of the bonds of 4.00% Series, but the Company may require payment of a sum sufficient to cover any tax or taxes or other governmental charges required to be paid by the Company in relation thereto.

 The bonds of 4.00% Series shall be redeemable as set forth in the form of bond of the bonds of 4.00% Series set forth in this
One Hundred and Tenth Supplemental Indenture. 
 This bond is transferable as prescribed in the Mortgage by the registered
holder hereof in person, or by his or her duly authorized attorney, at the office or agency to be maintained by the Company in the Borough of Manhattan, The City of New York, upon surrender and cancellation of this bond, and thereupon a new fully
registered bond or bonds of authorized denominations of the same series and tranche and for the same aggregate principal amount will be issued to the transferee in exchange herefor as provided in the Mortgage, and in each case without payment of any
service or other similar charge as herein provided. The Company and the Trustee, any paying agent and any bond registrar may deem and treat the person in whose name this bond is registered as the absolute owner hereof, whether or not this bond shall
be overdue, for the purpose of receiving payment and for all other purposes and neither the Company nor the Trustee nor any paying agent nor any bond registrar shall be affected by any notice to the contrary. 

The bonds of 4.00% Series initially shall be represented by one or more securities in registered, global form without interest coupons (a
“Global Bond”). The Company initially appoints DTC to act as depositary with respect to the Global Bonds (together with any successor, the “Depositary”). The bonds of 4.00% Series initially shall be registered in the name of
Cede & Co. as nominee for DTC. 
 So long as the bonds of 4.00% Series are held by a depositary, such bonds of 4.00%
Series shall bear the following legend, in addition to any other legends required by such depositary: 
 “THIS BOND IS A
GLOBAL BOND WITHIN THE MEANING OF THE MORTGAGE HEREINAFTER REFERRED TO AND IS REGISTERED IN THE NAME OF A DEPOSITARY OR A NOMINEE THEREOF. THIS BOND MAY NOT BE TRANSFERRED TO, OR REGISTERED OR EXCHANGED FOR BONDS REGISTERED IN THE NAME OF, ANY
PERSON OTHER THAN THE DEPOSITARY OR A NOMINEE THEREOF, AND NO SUCH TRANSFER MAY BE REGISTERED, EXCEPT IN THE LIMITED CIRCUMSTANCES DESCRIBED IN THE MORTGAGE. EVERY BOND AUTHENTICATED AND DELIVERED UPON REGISTRATION OF TRANSFER OF, OR IN EXCHANGE FOR
OR IN LIEU OF, THIS BOND SHALL BE A GLOBAL BOND THAT IS SUBJECT TO THE FOREGOING, EXCEPT IN SUCH LIMITED CIRCUMSTANCES.” 

Any bonds of 4.00% Series authenticated and delivered upon registration of transfer of, or in exchange for, or in lieu of, any Global
Bond shall also be a Global Bond and shall bear the foregoing legend, except for any bond authenticated and delivered in exchange for, or upon registration of transfer of, a Global Bond pursuant to the next paragraph. 

  
 10 

 Notwithstanding anything herein to the contrary, a Global Bond shall not be exchangeable for
bonds of 4.00% Series registered in the name of, and no transfer of a Global Bond may be registered to, any person other than the Depositary or its nominee, unless (i) such Depositary (A) notifies the Company that it is unwilling or unable
to continue as Depositary for the bonds of 4.00% Series or (B) ceases to be a “clearing agency” registered under the Securities Exchange Act of 1934, as amended, and the Company within 90 days after it receives such notice or becomes
aware of such ineligibility does not appoint a successor Depositary, (ii) the Company executes and delivers to the Trustee a notice that the bonds of 4.00% Series shall be so exchangeable and the transfer thereof so registerable, or
(iii) there shall have occurred a completed default as in the Mortgage provided with respect to the bonds of 4.00% Series evidenced by such Global Bond. Upon the occurrence in respect of the bonds of 4.00% Series of (1) the condition
specified in clause (i) of the preceding sentence, the bonds of 4.00% Series shall be exchanged, and (2) any one or more of the conditions specified in clause (ii) or (iii) of the preceding sentence, the bonds of 4.00% Series
shall be exchangeable, for bonds registered in the names of, and the transfer of such bond shall be registered to, the beneficial owners of the bonds of the bonds of 4.00% Series, or their designees, as the Depositary shall direct. The bonds of
4.00% Series issued to beneficial owners, or their designees shall be substantially in the form set forth in the One Hundred and Tenth Supplemental Indenture, but shall not include the provision related to the Global Bonds. 

The Company and the Trustee may rely conclusively upon (a) a certificate of the Depository as to the identity of a participant in
the book-entry system; (b) a certificate of any participant as to the identity of any indirect participant and (c) a certificate of any participant or any indirect participant as to the identity of, and the respective principal amount of
bonds of 4.00% Series owned by, beneficial owners. 
 SECTION 2. The principal amount of the bonds of 4.00% Series that may be
authenticated and delivered hereunder is not limited, except as the Indenture limits the principal amount of bonds that may be issued thereunder. 
 SECTION 3. Bonds of 4.00% Series for the aggregate principal amount of Two Hundred Fifty Million Dollars ($250,000,000), being the initial issuance of bonds of 4.00% Series, shall forthwith be executed by
the Company and delivered to the Trustee and shall be authenticated by the Trustee and delivered, after the recording hereof, in accordance with the request of the Company, signed in the name of the Company by its President or one of its Vice
Presidents and its Treasurer or one of its Assistant Treasurers, upon compliance by the Company with the applicable provisions of Articles III and IV of the Indenture. 
 ARTICLE II.

supplemental thereto are in all respects ratified and confirmed and the Original Indenture and the aforesaid supplemental indentures and this One Hundred and Tenth Supplemental Indenture shall be read, taken and construed as one and the same
instrument.

counterparts, and all such counterparts executed and delivered, each as an original, shall constitute but one and the same instrument.
