Company’s the 1995 Stock Plan of NexGen, Inc., 1996 Stock Incentive Plan, the 1998 Stock Incentive Plan and the 2000 Stock Incentive Plan (the “Prior Plans”) that are not subject to outstanding awards under the Prior Plans on

exercise of Awards exceed one hundred eighty (180) million Shares (adjusted in proportion to any adjustments under Section 15(a)) over the term of the Plan.

 4. Administration of the Plan. 
 (a) Procedure. 
 (i)
Section 162(m). To the extent that the Administrator determines it to be desirable to qualify Awards granted hereunder as “performance-based compensation” within the meaning of Section 162(m) of the Code, the transactions
contemplated hereunder shall be structured to satisfy the requirements for exemption of “performance-based compensation” under Section 162(m) of the Code and related regulations. 
 (ii) Rule 16b-3. To the extent that the Administrator determines it to be desirable to qualify transactions hereunder as exempt under Rule 16b-3,
the transactions contemplated hereunder shall be structured to satisfy the requirements for exemption under Rule 16b-3. 
 (iii) Other
Administration. Other than as provided above, the Plan shall be administered by the Administrator in a manner to satisfy Applicable Laws. 
 (b) Powers of the Administrator. Subject to the provisions of the Plan, including, without limitation Section 17, and in the case of a Board delegate, subject to the specific duties delegated by the Board to such Board delegate,
the Administrator shall have the authority, in its discretion: 
 (i) to determine the Fair Market Value as defined above; 
 (ii) to select the Service Providers to whom Awards may be granted hereunder; 
 (iii) to determine the number of shares of Common Stock to be covered by each Award granted hereunder; 
 (iv) to approve forms of agreement and documentation 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 Options or SARs may be exercised (which may be based on performance criteria), transferability, any vesting acceleration or waiver of forfeiture or repurchase restrictions,
and any restriction or limitation regarding any Award or the shares of Common Stock relating thereto, based in each case on such factors as the Administrator, in its sole discretion, shall 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 qualifying for preferred tax treatment under foreign tax laws; 
  

 7 

 (viii) to modify or amend each Award (subject to Section 17 of the Plan), including the
discretionary authority to extend the post termination exercisability period of Options or SARs 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 or vesting of an Award that number of Shares or cash having a Fair Market Value
equal to the amount required to be withheld. The Fair Market Value of any Shares to be withheld shall 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 shall 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 effect the grant of an Award previously granted by the Administrator; 
 (xi) 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 shall be final and binding on all Participants. 
 5. Eligibility. Nonstatutory Stock Options, Restricted Stock, Restricted Stock Units, and Stock Appreciation Rights may be granted to Service Providers. Incentive Stock Options may only be granted to
employees of the Company and any Parent or Subsidiary of the Company. 
 6. Limitations on Awards. 
 (a) No Rights as a Service Provider. Neither the Plan nor any Award shall confer upon a Participant any right with respect to continuing their
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 any Affiliate to terminate such relationship at any time, with or without cause or to adjust the compensation of
any Participant. 
 (b) Exercise; Rights as a Stockholder; Effect of Exercise. 
 (i) Any Award granted hereunder shall be exercisable or vest 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 Documentation, including, without limitation, Participant’s continuous status as a Service Provider and/or Participant’s satisfaction of Performance Goals. An Award may not be exercised for a
fraction of a Share. An Award shall be deemed exercised when the Company receives written or electronic notice of exercise (in accordance with the Award Documentation) from the person entitled to exercise the Award. The Participant must remit to the
Company full payment for the Shares with respect to which the Award is exercised. Full payment may consist of any consideration and method of payment authorized by the Administrator and permitted by the Award Documentation and the Plan. Shares
issued upon exercise of an Award shall be issued in the name of the Participant or, if 
  

 8 

 requested by the Participant, in the name of the Participant and Participant’s spouse, or after the death of the
Participant in the name of the Participant’s beneficiaries or heirs or as directed by the executor of Participant’s estate under applicable law. 
 (ii) 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 shall exist with respect to the Awarded Stock, notwithstanding the exercise of the Award. The Company shall issue (or cause to be issued) such Shares promptly after the Award is exercised or vests. No adjustment of an Award 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(a) of the Plan or specified in such Award’s Award Documentation. 
 (iii) Exercising an Award in any manner that results in the issuance of Shares shall decrease the number of Shares thereafter available, both for
purposes of the Plan and for issuance under the Award, by the number of Shares as to which the Award is exercised. 
 (c) Misconduct.
If a Participant is determined by the Administrator to have committed Misconduct then, unless otherwise provided in a Participant’s agreement for services as a Service Provider, neither the Participant, the Participant’s estate nor such
other person who may then hold any Award granted to the Participant shall be entitled to exercise any such Award with respect to any Shares, after termination of status as a Service Provider, whether or not the Participant may receive from the
Company (or Affiliate) payment for: vacation pay, services rendered prior to termination, services rendered for the day on which termination occurs, salary in lieu of notice, or any other benefits. In making such determination, the Administrator
shall give the Participant an opportunity to present evidence to the Administrator. Unless otherwise provided in a Participant’s agreement for services as a Service Provider, termination of status as a Service Provider shall be deemed to occur
on the date when the Company (or Affiliate) dispatches notice or advice to the Participant that status as a Service Provider is terminated. 
 (d) 162(m) Limitations. 
 (i) Except in connection with his or her initial service, no Service Provider shall be granted, in
any calendar year, Awards covering in the aggregate more than 2,000,000 Shares. 
 (ii) In connection with his or her initial service, a
Service Provider may be granted Awards covering in the aggregate up to 4,000,000 Shares in the first twelve (12) months of such Service Provider’s service, rather than the limit set forth in subsection (i) above. 
 (iii) The foregoing limitations shall be adjusted proportionately in connection with any change in the Company’s capitalization as described in
Section 15(a). 
 (iv) If an Award is cancelled in the same fiscal year of the Company in which it was granted (other than in
connection with a transaction described in 
  

 9 

 Section 15(b), the cancelled Award will be counted against the limits set forth in subsections (i) and
(ii) above. 
 (e) Tax Withholding. 
 (i) Where, in the opinion of counsel to the Company, the Company has or will have an obligation to withhold foreign, federal, state or local taxes relating to the exercise of any Award, the Administrator may in its
discretion require that such tax obligation be satisfied in a manner satisfactory to the Company. With respect to the exercise of an Award, the Company may require the payment of such taxes before Shares deliverable pursuant to such exercise are
transferred to the holder of the Award. 
 (ii) With respect to the exercise of an Award, a Participant may elect (a “Withholding
Election”) to pay the minimum statutory withholding tax obligation by the withholding of Shares from the total number of Shares deliverable pursuant to the exercise of such Award, or by delivering to the Company a sufficient number of
previously acquired shares of Common Stock, and may elect to have additional taxes paid by the delivery of previously acquired shares of Common Stock, in each case in accordance with rules and procedures established by the Administrator. Previously
owned shares of Common Stock delivered in payment for such additional taxes must have been owned for at least six months prior to the delivery or must not have been acquired directly or indirectly from the Company and may be subject to such other
conditions as the Administrator may require. The value of each Share withheld, or share of Common Stock delivered, shall be the Fair Market Value per share of Common Stock on the date the Award becomes taxable. All Withholding Elections are subject
to the approval of the Administrator must be made in compliance with rules and procedures established by the Administrator. 
 7. Term of
Plan. The Plan shall become effective upon its adoption by the Board, subject to stockholder approval. It shall continue in effect for a term of ten (10) years unless terminated earlier under Section 17 of the Plan. 
 8. Options. 
 (a) Term of
Options. The term of each Option shall be not greater than ten (10) years from the date it was granted. 
 (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 shall be determined by the Administrator, subject to the following: 
 (ii) In the case of an ISO granted to any Employee who, at
the time the ISO is granted owns stock representing more than ten percent (10%) of the voting power of all classes of stock of the Company or any Affiliate, the per Share exercise price shall be no less than 110% of the Fair Market Value per
Share on the date of grant. 
  

 10 

 (iii) In the case of an ISO granted to any Employee other than an Employee described in subsection
(ii) immediately above, the per Share price shall be no less than 100% of the Fair Market Value per Share on the date of the grant. 
 (iv) In the case of a NSO, the per Share exercise price shall be no less than 100% of the Fair Market Value per Share on the date of grant. 
 (v) The exercise price for the Shares to be issued pursuant to an already granted Option may not be changed without the consent of the Company’s stockholders. This shall include, without limitation, a repricing
of the Option as well as an option exchange program whereby the Participant agrees to cancel an existing Option in exchange for an Option, SAR or other Award. 
 (c) Form of Consideration. The Administrator shall 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 shall 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) check 
 (ii) other Shares which
(A) in the case of Shares acquired upon exercise of an Option, have been owned by the Participant for more than six months on the date of surrender, and (B) have a Fair Market Value on the date of surrender equal to the aggregate exercise
price of the Shares as to which said Option shall be exercised; 
 (iii) broker-assisted cashless exercise; or 
 (iv) any combination of the foregoing methods of payment; or 
 (v) such other consideration and method of payment for the issuance of Shares to the extent permitted by Applicable Laws. 
 (d) Termination of Relationship as Service Provider. When a Participant’s status as a Service Provider terminates, other than from Misconduct, death or Disability, the Participant’s Option may be
exercised within the period of time specified in the Option Agreement to the extent that the Option is vested on the date of termination or such longer period of time determined by the Administrator (which may so specify after the date of the
termination but before expiration of the Option) not to exceed five (5) years (but in no event later than the expiration of the term of such Option as set forth in the Option Agreement). In the absence of a specified period of time in the Plan
or the Award Documentation, the Option shall remain exercisable for three (3) months following the date Participant ceased to be a Service Provider. If, on the date of termination, such Participant’s Option is not fully vested, then the
unvested Shares shall revert to the Plan. If, after termination, the Participant’s Option is not fully exercised within the time specified, then the unexercised Shares covered by such Option shall revert to the Plan and such Option shall
terminate. 
  

 11 

 (e) Death or Disability of Participant. If a Participant’s status as a Service Provider
terminates from death or Disability, then the Participant or the Participant’s estate, or such other person as may hold the Option, as the case may be, shall have the right for a period of twelve (12) months following the date of death or
termination of status as a Service Provider for Disability, or for such other period as the Administrator may fix, to exercise the Option to the extent the Participant was entitled to exercise such Option on the date of death or termination of
status as a Service Provider for Disability, or to such extent as may otherwise be specified by the Administrator (which may so specify after the date of death or Disability but before expiration of the Option), provided the actual date of exercise
is in no event after the expiration of the term of the Option. A Participant’s estate shall mean his legal representative or any person who acquires the right to exercise an Option by reason of the Participant’s death or Disability.

 (f) Events Not Deemed Terminations: Unless otherwise provided in a Participant’s agreement for services as a Service
Provider, such Participant’s status as a Service Provider shall not be considered interrupted in the case of (i) a leave of absence (approved by the Administrator) by a Participant who intends throughout such leave to return to providing
services as a Director, Employee, or Consultant; (ii) sick leave; (iii) military leave; (iv) any other leave of absence approved by the Administrator, provided such leave is for a period of not more than ninety (90) days, unless
reemployment upon the expiration of such leave is guaranteed by contract or statute, or unless provided otherwise pursuant to formal policy adopted from time to time by the Company and issued and promulgated to employees in writing; or (v) in
the case of transfer between locations of the Company or among the Company and its Affiliates. In the case of any Participant on an approved leave of absence, the Administrator may make such provisions respecting suspension of vesting of the Option
while on a leave described in subparts (i) through (v) above and/or resumption of vesting on return from such leave as it may deem appropriate, except that in no event shall an Option be exercised after the expiration of the term set forth
in the Option. 
 (g) ISO Rules. The Option Agreement for each ISO shall contain a statement that the Option it documents is an ISO.
However, notwithstanding such designation, to the extent that the aggregate Fair Market Value of the Shares with respect to which all ISOs held by a Participant are exercisable for the first time by such Participant during any calendar year exceeds
$100,000, such excess Shares shall be treated as Shares subject to an NSO. For purposes of this subsection 8(g), ISOs shall be taken into account in the order in which they were granted. The Fair Market Value of the Shares subject to an ISO shall be
determined as of the time the ISO with respect to such Shares is granted. 
 (h) Buyout Provisions. Subject to Section 8(b)(v),
the Administrator may offer to buy out for a payment in cash or Shares an Option previously granted based on such terms and conditions as the Administrator shall establish and communicate to the Participant at the time that such offer is made;
provided that the Administrator shall not make such offer without the consent of the Company’s stockholders with respect to an Option with a per share exercise price that is greater than Fair Market Value on the date of such offer.

 9. Stock Appreciation Rights. 
 (a) Grant of SARs. Subject to the terms and conditions of the Plan, SARs may be granted to Service Providers at any time and from time to time as
shall be determined by the Administrator, in its sole discretion. The Administrator shall have complete discretion to determine the number of SARs granted to any Participant. 
 (b) Exercise Price and other Terms. The Administrator, subject to the provisions of the Plan, shall have complete discretion to determine the
terms and conditions of SARs granted under the Plan; provided, however, that no SAR may have a term of more than ten (10) years from the date of grant. In the case of an SAR, the per Share exercise price shall be no less than 100% of the Fair
Market Value per Share on the date of grant. The exercise price for the Shares or cash to be issued pursuant to an already granted SAR may not be changed without the consent of the Company’s stockholders. This shall include, without limitation,
a repricing of the SAR as well as an SAR exchange program whereby the Participant agrees to cancel an existing SAR in exchange for an Option, SAR or other Award. 
 (c) Payment of SAR Amount. Upon exercise of an SAR, a Participant shall be entitled to 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 
 (ii) the number of Shares with respect to which the SAR is exercised. 
 (d) Payment upon Exercise of SAR. At the discretion of the Administrator, payment for an SAR may be in cash, Shares or a combination thereof. 
 (e) SAR Agreement. Each SAR grant shall be evidenced by Award Documentation (a “SAR Agreement’) that shall specify the exercise price,
the term of the SAR, the conditions of exercise, and such other terms and conditions as the Administrator, in its sole discretion, shall determine. 
 (f) Expiration of SARs. An SAR granted under the Plan shall expire upon the date determined by the Administrator, in its sole discretion, and set forth in the Award Documentation. 
 (g) Termination of Relationship as Service Provider. When a Participant’s status as a Service Provider terminates, other than from
Misconduct, death or Disability, the Participant’s Stock Appreciation Right may be exercised within the period of time specified in the Stock Appreciation Right Agreement to the extent that the Stock Appreciation Right is vested on the date of
termination or such longer period of time determined by the Administrator (which may so specify after the date of the termination but before expiration of the Stock Appreciation Right) not to exceed five (5) years (but in no event later than
the expiration of the term of such Stock Appreciation Right as set forth in the Stock Appreciation Right Agreement). In the absence of a specified period of time in the Plan or the Stock Appreciation Right Agreement, the Stock Appreciation Right
shall remain exercisable for three (3) months following the date Participant ceased to be a Service Provider. If, on the date of termination, such Participant’s Stock Appreciation Right is not fully vested, then the unvested Shares shall

  

 13 

 revert to the Plan. If, after termination, the Participant’s Stock Appreciation Right is not fully exercised within
the time specified, then the unexercised Shares covered by such Stock Appreciation Right shall revert to the Plan and such Stock Appreciation Right shall terminate. 
 (h) Death or Disability of Participant. If a Participant’s status as a Service Provider terminates from death or Disability, then the Participant or the Participant’s estate, or such other person as
may hold the SAR, as the case may be, shall have the right for a period of twelve (12) months following the date of death or termination of status as a Service Provider for Disability, or for such other period as the Administrator may fix, to
exercise the SAR to the extent the Participant was entitled to exercise such SAR on the date of death or termination of status as a Service Provider for Disability, or to such extent as may otherwise be specified by the Administrator (which may so
specify after the date of death or Disability but before expiration of the SAR), provided the actual date of exercise is in no event after the expiration of the term of the SAR. A Participant’s estate shall mean his legal representative or any
person who acquires the right to exercise an SAR by reason of the Participant’s death or Disability. 
 (i) Events Not Deemed
Terminations. Unless otherwise provided in a Participant’s agreement for services as a Service Provider, such Participant’s status as a Service Provider shall not be considered interrupted in the case of (i) a leave of absence
(approved by the Administrator) by a Participant who intends throughout such leave to return to providing services as a Director, Employee, or Consultant; (ii) sick leave; (iii) military leave; (iv) any other leave of absence approved
by the Administrator, provided such leave is for a period of not more than ninety (90) days, unless reemployment upon the expiration of such leave is guaranteed by contract or statute, or unless provided otherwise pursuant to formal policy
adopted from time to time by the Company and issued and promulgated to employees in writing; or (v) in the case of transfer between locations of the Company or among the Company and its Affiliates. In the case of any Participant on an approved
leave of absence, the Administrator may make such provisions respecting suspension of vesting of the Stock Appreciation Right while on a leave described in subparts (i) through (v) above and/or resumption of vesting on return from such
leave as it may deem appropriate, except that in no event shall a Stock Appreciation Right be exercised after the expiration of the term set forth in the Stock Appreciation Right. 
 (j) Buyout Provisions. Subject to Section 9(b), the Administrator may offer to buy out for a payment in cash or Shares an SAR previously
granted based on such terms and conditions as the Administrator shall establish and communicate to the Participant at the time that such offer is made; provided that the Administrator shall not make such offer without the consent of the
Company’s stockholders with respect to an SAR with a per share exercise price that is greater than Fair Market Value on the date of such offer. 
 10. Restricted Stock. 
 (a) Grant of Restricted Stock. Subject to the terms and conditions of
the Plan, Restricted Stock may be granted to Service Providers at any time and from time to time as shall be determined by the Administrator, in its sole discretion. 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, the vesting of which 
  

 14 

 typically will be based on continued provision of services and/or satisfaction of Performance Goals. Restricted Stock
that is based only on continued service may not vest for at least three years from the date of grant. Restricted Stock that is based on satisfaction of Performance Goals may not vest for at least one year from the date of grant. Once the Shares are
issued, voting, dividend and other rights as a stockholder shall exist with respect to Restricted Stock. 
 (b) Other Terms. The
Administrator, subject to the provisions of the Plan, shall have complete discretion to determine the terms and conditions, including the purchase price, if any, of Restricted Stock granted under the Plan. Restricted Stock grants shall be subject to
the terms, conditions, and restrictions determined by the Administrator at the time the Restricted Stock is granted. Any certificates representing the Restricted Stock shall bear such legends as shall be determined by the Administrator. 

(c) Restricted Stock Award Documentation. Each Restricted Stock grant shall be evidenced by Award Documentation (a “Restricted Stock
Award Documentation”) that shall specify the purchase price (if any) and such other terms conditions, and restrictions as the Administrator, in its sole discretion, shall determine. 
 11. Restricted Stock Units. 
 (a)
Grant of Restricted Stock Units. Subject to the terms and conditions of the Plan, Restricted Stock Units may be granted to Service Providers at any time and from time to time as shall be determined by the Administrator, in its sole
discretion. The Administrator shall have complete discretion to determine (i) the number of Shares subject to each Restricted Stock Units award, and (ii) the conditions that must be satisfied, the vesting of which typically will be based
on continued provision of services and/or satisfaction of Performance Goals. Restricted Stock Units that are based only on continued service may not vest for at least three years from the date of grant. Restricted Stock Units that are based on
satisfaction of Performance Goals may not vest for at least one year from the date of grant. Until the Shares are issued, no right to vote or receive dividends or any other rights as a stockholder shall exist with respect to Restricted Stock Units.

 (b) Other Terms. The Administrator, subject to the provisions of the Plan, shall have complete discretion to determine the terms
and conditions, including the purchase price, if any, of Restricted Stock Units granted under the Plan. Restricted Stock Units awards shall be subject to the terms, conditions, and restrictions determined by the Administrator at the time the
Restricted Stock Units award is granted. Restricted Stock Units shall be denominated in units with each unit equivalent to one Share for purposes of determining the number of Shares subject to any Restricted Stock Units award. 
 (c) Restricted Stock Units Agreement. Each Restricted Stock Units grant shall be evidenced by Award Documentation (a “Restricted Stock Units
Agreement”) that shall specify the purchase price, if any, and such other terms conditions, and restrictions as the Administrator, in its sole discretion, shall determine. Each Restricted Stock Units Agreement shall be subject to all applicable
terms of the Plan and may be subject to any other terms that are not inconsistent with the Plan. A Restricted Stock Units Agreement may provide for dividend equivalent units. 
  

 15 

 (d) Settlement. Settlement of vested Restricted Stock Units may be made in the form of
(i) cash, (ii) Shares or (iii) any combination, as determined by the Administrator and may be settled in a lump sum or in installments. Distribution to a Participant of an amount (or amounts) from settlement of vested Restricted Stock
Units may be deferred to a date after settlement as determined by the Administrator. The amount of a deferred distribution may be increased by an interest factor or by dividend equivalents. Until an Award of Restricted Stock Units is settled, the
number of such Restricted Stock Units shall be subject to adjustment pursuant to the Plan. 
 12. Awards to Outside Directors.
Notwithstanding anything herein to the contrary, the grant of any Award to a Director who is not also an Employee (an “Outside Director”) shall be made by the Board pursuant to a written non-discretionary formula established by the Board
(the “Outside Director Equity Compensation Policy”). The Outside Director Equity Compensation Policy shall set forth the type of Award(s) to be granted to Outside Directors, the number of shares of Common Stock to be subject to Outside
Director Awards, the conditions on which such Awards shall be granted, become exercisable and/or payable and expire, and such other terms and conditions as the Board determines in its discretion. 
 13. Non-Transferability of Awards. Unless determined otherwise by the Administrator, 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 recipient, only by the recipient. Notwithstanding the foregoing, in no event may an Award be
sold, pledged, assigned, hypothecated, transferred, or disposed of for consideration. If the Administrator makes an Award transferable in accordance with this Section 13, the Award Documentation for such Award shall contain such additional
terms and conditions as the Administrator deems appropriate. 
 14. Leaves of Absence. Unless the Administrator provides otherwise or
as otherwise required by Applicable Laws, vesting of Awards granted hereunder shall cease commencing on the thirty-first day of any unpaid leave of absence and shall only recommence upon return to active service. 
 15. Adjustments Upon Changes in Capitalization, Dissolution, Merger or Asset Sale. 
 (a) Subject to any required action by the stockholders of the Company, the number of shares of Common Stock covered by each outstanding Award, the number
of shares of Common Stock which have been authorized for issuance under the Plan but as to which no Awards have yet been granted or which have been returned to the Plan upon cancellation or expiration of an Award, in each case as set forth in
Section 3, as well as the price per share of Common Stock covered by each such outstanding Award and the 162(m) annual share issuance limits under Section 6(d) shall be proportionately adjusted for any increase or decrease in the number of
issued shares of Common Stock resulting from a stock split, reverse stock split, stock dividend, combination or reclassification of the Common Stock, or any other increase or decrease in the number of issued shares of Common Stock effected without
receipt of consideration by the Company; provided, however, that conversion of any convertible securities 
  

 16 

 of the Company shall not be deemed to have been “effected without receipt of consideration.” Such adjustment
shall be made by the Compensation Committee, whose determination in that respect shall be final, binding and conclusive. Except as expressly provided herein, no issuance by the Company of shares of stock of any class, or securities convertible into
shares of stock of any class, shall affect, and no adjustment by reason thereof shall be made with respect to, the number or price of shares of Common Stock subject to an Award. 
 (b) Dissolution or Liquidation. In the event of the proposed dissolution or liquidation of the Company, the Administrator shall 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 until ten (10) 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) Merger or Asset Sale. 
 (i) Stock Options and SARs. In the event of a merger of the Company with or into another corporation, or the sale of substantially all of the
assets of the Company, each outstanding Option and SAR shall be assumed or an equivalent option or SAR substituted by the successor corporation or related corporation. In the event that the successor corporation refuses to assume or substitute for
the Option or SAR, the Participant shall fully vest in and have the right to exercise the Option or SAR as to all of the Awarded Stock, including Shares as to which it would not otherwise be vested or exercisable. If an Option or SAR becomes fully
vested and exercisable in lieu of assumption or substitution in the event of a merger or sale of assets, the Administrator shall notify the Participant in writing or electronically that the Option or SAR shall be fully vested and exercisable for a
period of fifteen (15) days from the date of such notice, and the Option or SAR shall terminate upon the expiration of such period. For the purposes of this subsection, the Option or SAR shall be considered assumed if, following the merger or
sale of assets, the Option or SAR confers the right to purchase or receive, for each Share of Awarded Stock subject to the Option or SAR immediately prior to the merger or sale of assets, the consideration (whether stock, cash, or other securities
or property) received in the merger or sale of assets by holders of Common Stock for each Share held on the effective date of the transaction (and if holders were offered a choice of consideration, the type of consideration chosen by the holders of
a majority of the outstanding Shares); provided, however, that if such consideration received in the merger or sale of assets is not solely common stock of the successor corporation or related corporation, the Administrator may, with the consent of
the successor corporation, provide for the consideration to be received upon the exercise of the Option or SAR, for each Share of Awarded Stock subject to the Option or SAR, to be solely common stock of the successor corporation or related
corporation equal in fair market value to the per share consideration received by holders of Common Stock in the merger or sale of assets. 
  

 17 

 (ii) Restricted Stock and Restricted Stock Units. In the event of a merger of the Company with or
into another corporation, or the sale of substantially all of the assets of the Company, repurchase rights on Shares of Restricted Stock, or any consideration into which such Shares of Restricted Stock are converted as part of such merger or sale,
may be assigned to the successor corporation or related corporation, and each outstanding RSU shall be assumed or an equivalent award substituted by the successor corporation or related corporation of the successor corporation. If the successor
corporation refuses to assume or substitute for such Awards, then Participants shall fully vest in such Awards. If RSUs become fully vested and exercisable in lieu of assumption or substitution in the event of a merger or sale of assets, the
Administrator shall notify Participants in writing or electronically that their RSUs shall be fully vested and exercisable for a period of fifteen (15) days from the date of such notice, and such RSUs shall terminate upon the expiration of such
period. RSUs shall be considered assumed if, following the merger or sale of assets, such RSUs confer the right to purchase or receive, for each Share subject to such RSUs immediately prior to the merger or sale of assets, the consideration (whether
stock, cash, or other securities or property) received in the merger or sale of assets by holders of Common Stock for each share of Common Stock held on the effective date of the transaction (and if holders were offered a choice of consideration,
the type of consideration chosen by the holders of a majority of the outstanding shares of Common Stock); provided, however, that if such consideration received in the merger or sale of assets is not solely common stock of the successor corporation
or related corporation, then the Administrator may, with the consent of the successor corporation, provide for the consideration to be received, for each Share subject to such RSUs, to be solely in the form of common stock of the successor
corporation or related corporation equal in fair market value to the per share consideration received by holders of Common Stock in the merger or sale of assets. 
 (d) Change of Control. Unless otherwise provided in a Participant’s agreement for services as an employee of the Company, if, within one year after a Change of Control has occurred, such Participant’s
status as an employee of the Company is terminated by the Company (including for this purpose any successor to the Company due to such Change of Control and any employer that is an Affiliate of such successor) for any reason other than for
Misconduct or, if applicable, terminated by such Participant as a Constructive Termination, then all Awards held by such Participant shall become fully vested for exercise upon the date of termination of such status, irrespective of the vesting
provisions of such Participant’s Award Documentations. 
 16. Date of Grant. The date of grant of an Award shall 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 shall be provided to each recipient within a reasonable time after
the date of such grant. 
 17. Amendment and Termination of the Plan. 
 (a) Amendment and Termination. The Board may at any time amend, alter, suspend or terminate the Plan. 
 (b) Stockholder Approval. The Company shall obtain stockholder approval of any Plan amendment to the extent necessary and desirable to comply
with 
  

 18 

 Applicable Laws and shall obtain stockholder approval for any amendment to the Plan to increase the number of shares
available under the Plan, to change the class of employees eligible to participate in the Plan or to provide for additional material benefits under the Plan. 
 (c) Effect of Amendment or Termination. No amendment, alteration, suspension or termination of the Plan shall impair the rights of any Participant, unless mutually agreed otherwise between the Participant and
the Administrator, which agreement must be in writing and signed by the Participant and the Company. Termination of the Plan shall 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. 
 18. Conditions Upon Issuance of Shares. 
 (a) Legal Compliance. Shares shall not be issued pursuant to the exercise of an Award unless the exercise of the Award or the issuance and
delivery of such Shares (or the cash equivalent thereof) shall comply with Applicable Laws and shall be further subject to the approval of counsel for the Company with respect to such compliance. Notwithstanding any other provision in this Plan, the
Company will have no obligation to issue or deliver certificates for Shares under this Plan prior to: (a) obtaining any approvals from governmental agencies that the Company determines are necessary or advisable; and/or (b) completion of
any registration or other qualification of such Shares under Applicable Laws. The Company will be under no obligation to register the Shares with the United States Securities and Exchange Commission or to effect compliance with the registration,
qualification or listing requirements of any state securities laws, stock exchange or automated quotation system, and the Company will have no liability for any inability or failure to do so. 
 (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. 
 19. 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 (or the cash equivalent thereof), shall relieve the Company of any
liability in respect of the failure to issue or sell such Shares (or the cash equivalent thereof) as to which such requisite authority shall not have been obtained. 
 20. Reservation of Shares. The Company, during the term of this Plan, will at all times reserve and keep available such number of Shares as shall be sufficient to satisfy the requirements of the Plan.

 21. Stockholder Approval. This Plan shall be subject to approval by the stockholders of the Company within twelve (12) months
after the date of adoption by the Board. Such stockholder approval shall be obtained in the manner and to the degree required under Applicable Laws.

 The Company does further covenant and agree with the Trustee as follows: 
 ARTICLE I 
 SERIES DDD BONDS

 Section 1: There is hereby created, for issuance under the Original Indenture as supplemented by the said Supplemental
Indentures (including this Fifty-Second Supplemental Indenture), a series of bonds designated Series DDD, due 2026, each of which shall bear the descriptive title “First Mortgage Bonds, Series DDD, due 2026” (herein sometimes referred to
as “Series DDD Bonds”), and the form thereof shall contain suitable provisions with respect to the matters hereinafter in this Section specified. The Series DDD Bonds shall mature on June 1, 2026 and shall be issued in
denominations of $1,000 and integral multiples thereof as the Company may from time to time execute and deliver. The Series DDD Bonds shall bear interest at the rate and from the date, shall be expressed to mature as to principal, and shall be
payable as to principal and interest at such place or places and in such money, all as provided in the form of Series DDD Bond set forth on Exhibit A hereto (the “Form of Bond”) and by the applicable provisions of the
Indenture. In addition, June 8, 2006 shall be an Interest Payment Date for the Series DDD Bonds for purposes of Section 9 of Article II of the Indenture, provided that no interest shall be payable on such date. Both the principal
and interest on the Series DDD Bonds shall be payable at the corporate trust office of the Trustee in the City and County of San Francisco, State of California. The Series DDD Bonds shall be dated as in Section 9 of Article II of the Indenture
provided with respect to registered bonds without coupons. 
 The Series DDD Bonds shall further be redeemable, exchangeable, transferable
and otherwise have the terms set forth in the Form of Bond. 
 The Series DDD Bonds shall otherwise be of such terms, provisions, tenor and
form as provided in this Fifty-Second Supplemental Indenture. 
 Section 2: The Series DDD Bonds shall be executed, authenticated
and delivered in accordance with the provisions and shall be entitled to the protection and security, of the Original Indenture supplemented by this Fifty-Second Supplemental Indenture and the other supplemental indentures, and shall be subject to
all of the terms, conditions and covenants and limitations thereof. The aggregate principal amount of the Series DDD Bonds, which may be executed by the Company and authenticated and delivered by the Trustee and secured by the Indenture as from time
to time in effect, is limited only to the extent provided in Section 1 of Article II of the Original Indenture. 
 Section 3: The Series DDD Bonds shall be issued only as fully registered bonds without coupons. The fully registered bonds without coupons and the certificate of authentication to be endorsed on all Series DDD Bonds shall be
substantially in the form set forth on the Form of Bond. In addition, the Series DDD Bonds may be issuable in whole or in part in the form of one or more securities that evidences all or part of the bonds of such series which is issued to a
depository or a nominee thereof for such series (a “Global Security”) and, in such case, the Board of Directors of the Company shall appoint a clearing agency registered under the Securities Exchange Act of 1934, as amended (the
“Exchange Act”), designated to act as depositary (a “depositary”) for such Global Securities. The definitive Series DDD Bonds shall be numbered in such manner as the Company shall at any time or from time to time
determine. 
 Section 4: In the event the Series DDD Bonds are issued as a Global Security the following provisions, in addition
to the provisions of the Indenture, shall apply: 
 (1) Each Global Security authenticated under the Indenture shall be registered in the name
of the depositary designated for such Global Security or a nominee thereof and delivered to such depositary or a nominee thereof or custodian therefor, and each such Global Security shall constitute a single bond for all purposes of this
Supplemental Indenture. 
 (2) Notwithstanding any other provision in this Supplemental Indenture, no Global Security may be exchanged in
whole or in part for bonds registered, and no transfer of a Global Security in whole or in part may be registered, in the name of any person other than the depositary for such Global Security or a nominee thereof unless (A) such depositary has
notified the Company that it is unwilling or unable to continue as depositary for such Global Security and a successor depositary has not been appointed by the Company within 90 days of receipt by the Company 

  

 8 

 
of such notification, (B) if at any time the depositary ceases to be a clearing agency registered under the Exchange Act at a time when the depositary
is required to be so registered to act as such depositary and no successor depositary shall have been appointed by the Company within 90 days after it became aware of such cessation, (C) the Company, in its sole discretion, executes and
delivers to the Trustee a written order signed in the name of the Company by its Chairman of the Board, its President or a Vice President, and by its Treasurer, an Assistant Treasurer, its Secretary or an Assistant Secretary to the effect that such
Global Security, together with all other Global Securities of the same series, shall be exchangeable as described below, or (D) a “completed default” (as defined in the Indenture) has occurred and is continuing with respect to the
Series DDD Bonds. If any of the events described in clauses (A) through (D) of the preceding sentence occur, the beneficial owners of interests in the relevant Global Securities will be entitled to exchange those interests for definitive
bonds and, without unnecessary delay but in any event not later than the earliest date on which those interests may be so exchanged, the Company will deliver to the Trustee definitive bonds in such form and denominations as are required by or
pursuant to this Indenture, and of the same series, containing identical terms and in an aggregate principal amount equal to the principal amount of such Global Securities, such bonds to be duly executed by the Company. On or after the earliest date
on which such beneficial interests may be so exchanged, such Global Securities shall be surrendered from time to time by the depositary as shall be specified in the order from the Company with respect thereto (which the Company agrees to deliver),
and in accordance with any instructions given to the Trustee and the depositary (which instructions shall be in writing but need not be contained in or accompanied by an officers’ certificate or be accompanied by an opinion of counsel), as
shall be specified in the order from the Company with respect thereto to the Trustee, as the Company’s agent for such purpose, to be exchanged, in whole or in part, for definitive bonds as described above without charge. The Trustee shall
authenticate and make available for delivery, in exchange for each portion of such surrendered Global Security, a like aggregate principal amount of definitive bonds of the same series of authorized denominations and of like tenor as the portion of
such Global Security to be exchanged. Promptly following any such exchange in part, such Global Security shall be returned by the Trustee to such depositary or its custodian. If a definitive bond is issued in exchange for any portion of a Global
Security after the close of business at the place where such exchange occurs on or after (i) any regular record date for the date the interest is due (the “Interest Payment Date”) for such bond and before the opening of
business at that place of payment on the next Interest Payment Date, or (ii) any special record date for the payment of interest for such bond and before the opening of business at such place of payment on the related proposed date for the
payment of the interest which was not punctually paid or duly provided for on any Interest Payment Date, as the case may be, interest shall not be payable on such Interest Payment Date or proposed date for payment, as the case may be, in respect of
such definitive bond, but shall be payable on the Interest Payment Date or proposed date for payment, as the case may be, only to the person to whom interest in respect of such portion of such Global Security shall be payable in accordance with the
provisions of this Indenture. 
 (3) Subject to Clause (2) above, any exchange or transfer of a Global Security for other bonds may be
made in whole or in part, and all bonds issued in exchange for or upon transfer of a Global Security or any portion thereof shall be registered in such names as the depositary for such Global Security shall direct. 
 (4) Every bond authenticated and delivered upon registration of transfer of, or in exchange for or in lieu of, a Global Security or any portion thereof,
shall be authenticated and delivered in the form of, and shall be, a Global Security, unless such bond is registered in the name of a person other than the depositary for such Global Security or a nominee thereof. 
 (5) Unless otherwise specified as contemplated by Section 1 of Article I of this Supplemental Indenture for the bonds evidenced thereby, every
Global Security authenticated and delivered hereunder shall bear a legend in substantially the following form: 
 THIS SECURITY IS A GLOBAL SECURITY WITHIN
THE MEANING OF THE INDENTURE HEREINAFTER REFERRED TO AND IS REGISTERED IN THE NAME OF A DEPOSITARY OR A NOMINEE THEREOF. THIS SECURITY MAY NOT BE EXCHANGED IN WHOLE OR IN PART FOR A SECURITY REGISTERED, AND NO TRANSFER OF THIS SECURITY IN WHOLE OR
IN PART MAY BE REGISTERED, IN THE NAME OF ANY PERSON OTHER THAN SUCH DEPOSITARY OR A NOMINEE THEREOF, EXCEPT IN THE LIMITED CIRCUMSTANCES DESCRIBED IN THE INDENTURE. ANY TRANSFER, PLEDGE, OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY
PERSON IS WRONGFUL INASMUCH AS THE REGISTERED OWNER HEREOF HAS AN INTEREST HEREIN. 
  

 9 

 Section 5: The Series DDD Bonds may contain or have imprinted thereon such provisions or
specifications not inconsistent with the Indenture as may be required to comply with the rules of any stock exchange or any federal or state authority or commission, or to comply with usage with respect thereto, and may bear such other appropriate
endorsements or notations as are authorized or permitted by the Indenture. 
 Section 6: In the manner and subject to certain
conditions and limitations specified herein and in the Indenture, Series DDD Bonds may be exchanged without a service charge for a like aggregate principal amount of such Series DDD Bonds of other authorized denomination or denominations;
provided that the Company may require payment of a sum or sums sufficient to reimburse it for any stamp tax or other governmental charge payable in connection therewith. 
 Section 7: The Company shall maintain in the City and County of San Francisco, State of California, and in such other place or places as the
Company may designate at any time or from time to time, an office or agency where Series DDD Bonds may be presented for payment, registration, transfer and exchange as provided therein or in the Indenture. Such office or agency in the City and
County of San Francisco shall be the corporate trust office of the Trustee unless and until the Company shall designate another office or agency by notice in writing delivered to the Trustee. Notwithstanding the foregoing, if and when definitive
bonds are issued, the Company shall maintain in the Borough of Manhattan, City and County of New York, State of New York, an office or agency where Series DDD Bonds may be presented for payment, registration, transfer and exchange as provided
therein or in the Indenture. 
 Section 8: No transfer or exchange of any Series DDD Bonds pursuant to any of the provisions of
this Article I shall be made except upon and in accordance with all of the applicable terms, provisions and conditions of said bonds and of the Indenture. 
 ARTICLE II 
 MISCELLANEOUS PROVISIONS 
 Section 1: This instrument is executed and shall be construed as an indenture supplemental to the Original Indenture and shall form a part
thereof and, as supplemented by this Fifty-Second Supplemental Indenture, the Original Indenture as heretofore supplemented and amended is hereby confirmed.

facilitate the filing of this Fifty-Second Supplemental Indenture the same may be executed in several counterparts each of which, when so executed, shall be deemed to be an original, but such counterparts shall constitute but one and the same
instrument. 
 Section 4: All of the covenants, stipulations, promises and agreements in this Fifty-Second Supplemental Indenture
by or on behalf of the Company shall bind its successors and assigns, whether so expressed or not. 
 Section 5: To the extent
any provision in this Supplemental Indenture conflicts with any provision in the Indenture, the provisions of this Supplemental Indenture shall govern; provided, however, that in the event such conflict would require bondholder consent, the
terms and provisions of the Indenture shall govern. 
 Section 6: The Original Indenture, insofar as it applies to the Series DDD
Bonds, this Supplemental Indenture and the Series DDD Bonds shall be governed by and construed in accordance with the laws of the State of California, without regard to conflicts of laws principles thereof.

 This bond is one of a duly authorized issue of bonds of the Company, known as its First Mortgage Bonds,
of the series and designation indicated on the face hereof (the “Series DDD Bonds”), all issued and to be issued under and equally secured by a Mortgage and Deed of Trust dated July 1, 1940, and indentures supplemental thereto,
including the Fifty-Second Supplemental Indenture dated as of June 8, 2006 (which Mortgage and Deed of Trust, as so supplemented, is herein called the “Indenture”) executed by the Company to U.S. Bank National Association, as
Trustee (herein called the “Trustee”), to which Indenture reference is hereby made for a description of the property mortgaged, pledged, hypothecated and in which a security interest was granted, the nature and extent of the
security, the rights of the holders of the Series DDD Bonds as to such security, and the terms and conditions upon which the Series DDD Bonds may be issued under the Indenture and are secured. The principal hereof may be declared or may become due
on the conditions, in the manner and at the time set forth in the Indenture, upon the happening of a completed default as in the Indenture provided. 
 With the consent of the Company and to the extent permitted by and as provided in the Indenture, the rights and obligations of the Company or of the holders of the Series DDD Bonds, or the terms and provisions of the
Indenture or of any indentures supplemental thereto, may be modified or altered by the affirmative vote of the holders of the percentage of principal amount of bonds required by the Indenture; provided, however, that without the
consent of the holder hereof no such modification or alteration shall permit the reduction of the principal or the extension of the maturity of the principal of this bond, or the reduction of the rate of interest hereon, or any other modification of
the terms of payment of such principal or interest. 
 The Company, the Trustee, any paying agent, any registrar, and any depositary may deem
and treat the person in whose name this bond is registered as the absolute owner hereof for the purpose of receiving payment of or on account of the principal hereof and interest hereon and for all other purposes and shall not be affected by any
notice to the contrary. 
 All or a portion of the Series DDD Bonds may be redeemed at the Company’s option at any time or from time to
time. 
 The price at which the Series DDD Bonds will be redeemed (the “Redemption Price”) on the date fixed for such
redemption (the “Redemption Date”) will be equal to the greater of the following amounts: (a) 100% of the principal amount of the Series DDD Bonds being redeemed on the Redemption Date; or (b) the sum of the present values
of the remaining scheduled payments of principal and interest on the Series DDD Bonds being redeemed on that Redemption Date (not including any portion of any payments of accrued and unpaid interest to the Redemption Date) discounted to the
Redemption Date on a semiannual basis at the Adjusted Treasury Rate (as defined below) plus 15 basis points, as determined by the Reference Treasury Dealer (as defined below), plus, in each case, accrued and unpaid interest thereon to the Redemption
Date. Notwithstanding the foregoing, installments of interest on Series DDD Bonds that are due and payable on Interest Payment Dates falling on or prior to a Redemption Date will be payable on the Interest Payment Date to the registered holders of
such Series DDD Bonds as of the close of business on the relevant record date. The Redemption Price will be calculated on the basis of a 360-day year consisting of twelve 30-day months. 
 As more fully provided in and subject to the provisions of the Indenture, the Series DDD Bonds are also subject to redemption on any date, under certain
circumstances specified in Section 13 of Article XI of the Indenture in case of the disposition of certain properties of the Company, at 100% of the principal amount thereof, together with accrued interest thereon. 
 Notice of any redemption will be mailed at least 30 days but not more than 60 days before the Redemption Date to each registered holder of the Series DDD
Bonds to be redeemed. Once notice of redemption is mailed, the Series DDD Bonds called for redemption will become due and payable on the Redemption Date and at the applicable Redemption Price, plus accrued and unpaid interest to the Redemption Date.
Redemption will not be conditional upon receipt by the Trustee of monies sufficient to pay the Redemption Price. 
 Unless the Company
defaults in payment of the Redemption Price, on and after the Redemption Date interest will cease to accrue on the Series DDD Bonds or portions thereof called for redemption. The Company will pay the Redemption Price and any accrued interest once
the Series DDD Bonds are surrendered for redemption. If only a portion of the Series DDD Bonds are redeemed, the Trustee will deliver new Series DDD Bonds for the remaining portion without charge. 

 “Adjusted Treasury Rate” means, with respect to any Redemption Date, the rate per annum
equal to the semiannual 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. 
 “Comparable Treasury Issue” means the United States Treasury security selected by the Reference Treasury Dealer as
having a maturity comparable to the remaining term of the Series DDD Bonds 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 such Series DDD Bonds. 
 “Comparable Treasury Price” means, with respect to
any Redemption Date, (A) the average of the Reference Treasury Dealer Quotations for such Redemption Date, or (B) if only one Reference Treasury Dealer Quotation is received, such Quotation. 
 “Reference Treasury Dealer” means (A) Banc of America Securities, LLC, BNP Paribas Securities Corp. and Greenwich Capital Markets,
Inc. (or their affiliates which are Primary Treasury Dealers) and their successors; provided, however, that if any of the foregoing shall cease to be a primary U.S. Government securities dealer in the United States (a “Primary
Treasury Dealer”), the Company will substitute therefor another Primary Treasury Dealer; and (B) any other Primary Treasury Dealer(s) selected by the Company. 
 “Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any Redemption Date, the average, as
determined by the Company, 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 Company by such Reference Treasury Dealer at 5:00 p.m. (New York City
time) on the third business day preceding such Redemption Date. 
 In the event that the Company elects to redeem only a portion of the
Series DDD Bonds, the bonds to be redeemed shall be selected in accordance with the procedures of The Depository Trust Company, in the case of bonds represented by a global security, or by the Trustee by a method the Trustee deems to be fair and
appropriate, in the case of bonds that are not represented by a global security. 
 This bond is transferable as prescribed in the Indenture
by the registered owner hereof in person, or by his duty authorized attorney, at the corporate trust office of the Trustee in the City and County of San Francisco, State of California, upon surrender and cancellation of this bond and thereupon a new
registered bond of the same series and principal amount will be issued to the transferee in exchange therefor as provided in the Indenture, upon payment of any tax or taxes or other governmental charges required to be paid by the Company by reason
of such transfer. 
 The registered owner of any Series DDD Bond, at the option of such holder, may surrender the same, accompanied by a
written instrument of transfer in form approved by the Company duly executed by the registered owner, at the corporate trust office of the Trustee in the City and County of San Francisco, State of California, for cancellation in exchange for another
or other registered bonds of the said series of higher or lower authorized denominations of an aggregate principal amount equal to the aggregate principal amount of the bond or bonds so surrendered and bearing interest as provided in Section 9
of Article II of the Indenture, and upon payment of any tax or taxes or other governmental charges required to be paid by the Company by reason of such exchange and subject to the terms and conditions specified in the Indenture, thereupon the
Company shall execute and deliver to the Trustee and the Trustee shall authenticate and deliver such other bonds to such registered owner at its office or at such agency of the Company, at the option of such registered owner. 
 No recourse shall be had for the payment of the principal of (or premium, if any) or the interest on this bond, or any part thereof, or of any claim
based herein or in respect hereof or of said Indenture, against any incorporator, or any past, or future stockholder, officer or director, as such, of the Company or of any predecessor or successor corporation, either directly or through the
Company, or through any such predecessor or successor corporation, or through any receiver or a trustee in bankruptcy, whether, by virtue of any constitution, statute or rule of law or by the enforcement of any assessment or penalty or otherwise,
all such liability being, by the acceptance hereof and as part of the consideration for the issue hereof expressly waived and released, as more fully provided in the Indenture.
