Change in Control Agreement dated 1/22/04

 EXHIBIT 10(C) 
  
 CHANGE IN CONTROL AGREEMENT 
  
 THIS AGREEMENT, dated January 22, 2004, is made by and between Sierra Pacific Resources, a Nevada corporation (the “Company”), and Ernest
E. East (the “Executive”). 
  
 WHEREAS, the
Company considers it essential to the best interests of its stockholders to foster the continued employment of key management personnel; and 
  
 WHEREAS, the Board recognizes that, as is the case with many publicly held corporations, the possibility of a Change in Control exists and that
such possibility, and the uncertainty and questions which it may raise among management, may result in the departure or distraction of management personnel to the detriment of the Company and its stockholders; and 
  
 WHEREAS, the Board has determined that appropriate steps should be
taken to reinforce and encourage the continued attention and dedication of members of the management of the Company and its subsidiaries (collectively, “Sierra”), including the Executive, to their assigned duties without distraction in the
face of potentially disturbing circumstances arising from the possibility of a Change in Control; 
  
 NOW, THEREFORE, in consideration of the premises and the mutual covenants herein contained, the Company and the Executive hereby agree as
follows: 
  
 1. Defined Terms. The definitions of
capitalized terms used in this Agreement are provided in the last Section hereof. 
  
 2. Term of Agreement. Subject to the provisions of Section 12.2 hereof, the term of this Agreement shall commence on the date hereof and shall continue in effect through December 31, 2004; provided,
however, that if a Change in Control shall have occurred during the Term, the Term shall expire no earlier than twenty-four (24) months beyond the month in which such Change in Control occurred; and further provided,
however, that if a Potential Change in Control shall have occurred during the Term, the Term shall expire no earlier than the latter of (a) the date on which such potential Change in Control shall have been terminated, or (b) 24 months beyond
the date on which such potential Change in Control shall have resulted in a Change of Control.

 3. Company’s Covenants Summarized. In order to induce the Executive to remain in the employ
of Sierra and in consideration of the Executive’s covenants set forth in Section 4 hereof, the Company agrees, under the conditions described herein, to pay the Executive the Severance Payments and the other payments and benefits described
herein. Except as provided in Section 9.1 hereof, no Severance Payments shall be payable under this Agreement unless there shall have been (or, under the terms of the second sentence of Section 6.1 hereof, there shall be deemed to have been) a
termination of the Executive’s employment with Sierra following a Change in Control or potential Change in Control and during the Term. This Agreement shall not be construed as creating an express or implied contract of employment and, except
as otherwise agreed in writing between the Executive and Sierra, the Executive shall not have any right to be retained in the employ of Sierra. The obligations of the Company hereunder shall be deemed satisfied to the extent payments are made by
Sierra Pacific Power, Nevada Power, or any affiliate of the Company. 
  
 4. The Executive’s Covenants. The Executive agrees that, subject to the terms and conditions of this Agreement, in the event of a Potential Change in Control during the Term, the Executive will remain in the employ of the
Company until the earliest of (i) a date which is six (6) months from the date of such Potential Change of Control, (ii) the date of a Change in Control, (iii) the date of termination by the Executive of the Executive’s employment for Good
Reason or by reason of death, Disability or Retirement, or (iv) the termination by Sierra of the Executive’s employment for any reason. 
  
 5. Compensation Other Than Severance Payments. 
  
 5.1 Following a Change in Control or potential Change in Control and during the Term, during any period that the Executive fails to perform the
Executive’s full-time duties with Sierra as a result of incapacity due to physical or mental illness, the Company shall pay the Executive’s full salary to the Executive at the rate in effect at the commencement of any such period, together
with all compensation and benefits payable to the Executive under the terms of any compensation or benefit plan, program or arrangement maintained by Sierra during such period, until the Executive’s employment is terminated by Sierra for
Disability. 
  
 5.2 If the Executive’s employment shall be
terminated for any reason following a Change in Control or potential Change in Control and during the Term, the Company shall pay the Executive’s full salary to the Executive through the Date of Termination at the rate in effect immediately
prior to the Date of Termination or, if higher, the rate in effect immediately prior to the first occurrence of an event or circumstance constituting Good Reason, together with all compensation and benefits payable to the Executive through the Date
of Termination under the terms of Sierra compensation and benefit plans, programs or arrangements as in effect immediately prior to the Date of Termination or, if more favorable to the Executive, as in effect immediately prior to the first
occurrence of an event or circumstance constituting Good Reason. 
  

 2 

 5.3 If the Executive’s employment shall be terminated for any reason following a Change in Control
or potential Change in Control and during the Term, the Company shall pay to the Executive the Executive’s normal post-termination compensation and benefits as such payments become due. Such post-termination compensation and benefits shall be
determined under, and paid in accordance with, Sierra’s retirement, insurance and other compensation or benefit plans, programs and arrangements as in effect immediately prior to the Date of Termination or, if more favorable to the Executive,
as in effect immediately prior to the occurrence of the first event or circumstance constituting Good Reason. 
  
 6. Severance Payments. 
  
 6.1 Subject to Section 6.2 hereof, if the Executive’s employment is terminated following a Change in Control and during the Term, other than (A) by
Sierra for Cause, (B) by reason of death or Disability, or (C) by the Executive without Good Reason, then Sierra shall pay the Executive the amounts, and provide the Executive the benefits, described in this Section 6.1 (“Severance
Payments”), in addition to any payments and benefits to which the Executive is entitled under Section 5 hereof. For purposes of this Agreement, the Executive’s employment shall be deemed to have been terminated following a Change in
Control by Sierra without Cause or by the Executive with Good Reason, if (i) the Executive’s employment is terminated by Sierra without Cause prior to a Change in Control (whether or not a Change in Control ever occurs) and such termination was
at the request or direction of a Person who has entered into an agreement with the Company the consummation of which would constitute a Change in Control, (ii) the Executive terminates his employment for Good Reason prior to a Change in Control
(whether or not a Change in Control ever occurs) and the circumstance or event which constitutes Good Reason occurs at the request or direction of such Person, or (iii) the Executive’s employment is terminated by Sierra without Cause or by the
Executive for Good Reason and such termination or the circumstance or event which constitutes Good Reason is otherwise in connection with or in anticipation of a Change in Control (whether or not a Change in Control ever occurs). For purposes of any
determination regarding the applicability of the immediately preceding sentence, any position taken by the Executive shall be presumed to be correct unless the Company establishes to the Board by clear and convincing evidence that such position is
not correct. 
  
 (A) In lieu of any further
salary payments to the Executive for periods subsequent to the Date of Termination and in lieu of any severance benefit otherwise payable to the Executive under or pursuant to any contract or plan, except for any severance benefits relating to or
resulting from the Supplemental Executive Retirement Plan, whether as a consequence of a Change in Control or otherwise, the Company shall pay to the Executive a 
  
  

 3 

 lump sum severance payment, in cash, equal to three times the sum of (i) the Executive’s base salary
as in effect immediately prior to the Date of Termination or, if higher, in effect immediately prior to the first occurrence of an event or circumstance constituting Good Reason, and (ii) the target annual incentive award applicable to the Executive
pursuant to any annual bonus or incentive plan maintained by Sierra in respect of the fiscal year ending immediately prior to the fiscal year in which occurs the Date of Termination or, if higher, immediately prior to the fiscal year in which occurs
the first event or circumstance constituting Good Reason. 
  
 (B) For the thirty-six (36) month period immediately following the Date of Termination, the Company shall arrange to provide the Executive and his dependents life, disability, accident and health insurance benefits
substantially similar to those provided to the Executive and his dependents immediately prior to the Date of Termination or, if more favorable to the Executive, those provided to the Executive and his dependents immediately prior to the first
occurrence of an event or circumstance constituting Good Reason, at no greater cost to the Executive than the cost to the Executive immediately prior to such date or occurrence; provided, however, that, unless the Executive consents to
a different method (after taking into account the effect of such method on the calculation of “parachute payments” pursuant to Section 6.2 hereof), such health insurance benefits shall be provided through a third-party insurer. Benefits
otherwise receivable by the Executive pursuant to this Section 6.1(B) shall be reduced to the extent benefits of the same type are received by or made available to the Executive during the thirty-six (36) month period following the Executive’s
termination of employment (and any such benefits received by or made available to the Executive shall be reported to the Company by the Executive); provided, however, that the Company shall reimburse the Executive for the excess, if
any, of the cost of such benefits to the Executive over such cost immediately prior to the Date of Termination or, if more favorable to the Executive, the first occurrence of an event or circumstance constituting Good Reason. If the Severance
Payments shall be decreased pursuant to Section 6.2 hereof, and the Section 6.1(B) benefits which remain payable after the application of Section 6.2 hereof are thereafter reduced pursuant to the immediately preceding sentence, the Company shall, no
later than five (5) business days following such reduction, pay to the Executive the least of (a) the amount of the decrease made in the Severance Payments pursuant to Section 6.2 hereof, (b) the amount of the subsequent reduction in these Section
6.1(B) benefits, or (c) the maximum amount which can be paid to the Executive without being, or causing any other payment to be, nondeductible by reason of Section 280G of the Code. 
  
 (C) Notwithstanding any provision of any annual or long-term incentive plan to the contrary, the Company
shall pay to the Executive a lump sum amount, in cash, equal to the sum of (i) any unpaid incentive 
  
  

 4 

 compensation which has been allocated or awarded to the Executive for a completed fiscal year or other
measuring period preceding the Date of Termination under any such plan and which, as of the Date of Termination, is contingent only upon the continued employment of the Executive to a subsequent date, and (ii) a pro rata portion to the Date of
Termination of the aggregate value of all contingent incentive compensation awards to the Executive for all then uncompleted periods under any such plan, calculated as to each such award by multiplying the award that the Executive would have earned
on the last day of the performance award period, assuming the achievement, at the target level of the individual and corporate performance goals established with respect to such award, by the fraction obtained by dividing the number of full months
and any fractional portion of a month during such performance award period through the Date of Termination by the total number of months contained in such performance award period. 
  
 (D) In addition to the retirement benefits to which the Executive is entitled under each Pension Plan or any
successor plan thereto, the Company shall pay the Executive a lump sum amount, in cash, equal to the excess of (i) the actuarial equivalent of the aggregate retirement pension (taking into account any early retirement subsidies associated therewith
and determined as a straight life annuity commencing at the date (but in no event earlier than the third anniversary of the Date of Termination) as of which the actuarial equivalent of such annuity is greatest) which the Executive would have accrued
under the terms of all Pension Plans (without regard to any amendment to any Pension Plan made subsequent to a Change in Control and on or prior to the Date of Termination, which amendment adversely affects in any manner the computation of
retirement benefits thereunder), determined as if the Executive were fully vested thereunder and had accumulated (after the Date of Termination) thirty-six (36) additional months of service credit thereunder and had been credited under each Pension
Plan during such period with compensation equal to the Executive’s compensation (as defined in such Pension Plan) during the twelve (12) months immediately preceding the Date of Termination or, if higher, during the twelve months immediately
prior to the first occurrence of an event or circumstance constituting Good Reason, over (ii) the actuarial equivalent of the aggregate retirement pension (taking into account any early retirement subsidies associated therewith and determined as a
straight life annuity commencing at the date (but in no event earlier than the Date of Termination) as of which the actuarial equivalent of such annuity is greatest) which the Executive had accrued pursuant to the provisions of the Pension Plans as
of the Date of Termination. For purposes of this Section 6.1(D), “actuarial equivalent” shall be determined using the same assumptions utilized under the Sierra Pacific Power Company Retirement Plan immediately prior to the Date of
Termination. or, if more favorable to the Executive, immediately prior to the first occurrence of an event or circumstance constituting Good Reason. 
  

 5 

 (E) If the Executive would have become entitled to benefits under Sierra’s
post-retirement health care or life insurance plans, as in effect immediately prior to the Date of Termination or, if more favorable to the Executive, as in effect immediately prior to the first occurrence of an event or circumstance constituting
Good Reason, had the Executive’s employment terminated at any time during the period of thirty-six (36) months after the Date of Termination, the Company shall provide such post-retirement health care or life insurance benefits to the Executive
and the Executive’s dependents commencing on the later of (i) the date on which such coverage would have first become available and (ii) the date on which benefits described in subsection (B) of this Section 6.1 terminate. 
  
 6.2 (A) Notwithstanding any other provisions of this Agreement, in the event
that any payment or benefit received or to be received by the Executive in connection with a Change in Control or the termination of the Executive’s employment (whether pursuant to the terms of this Agreement or any other plan, arrangement or
agreement with the Company, any Person whose actions result in a Change in Control or any Person affiliated with the Company or such Person) (all such payments and benefits, including the Severance Payments, being hereinafter called “Total
Payments”) would be subject (in whole or part), to the Excise Tax, then, after taking into account any reduction in the Total Payments provided by reason of section 280G of the Code in such other plan, arrangement or agreement, the cash
Severance Payments shall first be reduced, and the non-cash Severance Payments shall thereafter be reduced, to the extent necessary so that no portion of the Total Payments is subject to the Excise Tax but only if (A) the net amount of such Total
Payments, as so reduced (and after subtracting the net amount of federal, state and local income taxes on such reduced Total Payments) is greater than or equal to (B) the net amount of such Total Payments without such reduction (but after
subtracting the net amount of federal, state and local income taxes on such Total Payments and the amount of Excise Tax to which the Executive would be subject in respect of such unreduced Total Payments); provided, however, that the
Executive may elect to have the non-cash Severance Payments reduced (or eliminated) prior to any reduction of the cash Severance Payments. 
  
 (B) For purposes of determining whether and the extent to which the Total Payments will be subject to the Excise Tax, (i) no portion of the Total Payments
the receipt or enjoyment of which the Executive shall have waived at such time and in such manner as not to constitute a “payment” within the meaning of Section 280G(b) of the Code shall be taken into account, (ii) no portion of the Total
Payments shall be taken into account which, in the opinion of tax counsel (“Tax Counsel”) reasonably acceptable to the Executive and selected by the accounting firm (the “Auditor”) which was, immediately prior to the Change in
Control, the Company’s independent auditor, does not constitute a “parachute payment” within the meaning of Section 280G(b)(2) of the Code (including by reason of Section 280G(b)(4)(A) of the Code) and, in calculating the Excise Tax,
no portion of such Total Payments shall be taken into account which, in the opinion of Tax 
  

 6 

 Counsel, constitutes reasonable compensation for services actually rendered, within the meaning of Section 280G(b)(4)(B)
of the Code, in excess of the Base Amount allocable to such reasonable compensation, and (iii) the value of any non-cash benefit or any deferred payment or benefit included in the Total Payments shall be determined by the Auditor in accordance with
the principles of Sections 280G(d)(3) and (4) of the Code. 
  
 (C)
At the time that payments are made under this Agreement, the Company shall provide the Executive with a written statement setting forth the manner in which such payments were calculated and the basis for such calculations including, without
limitation, any opinions or other advice the Company has received from Tax Counsel, the Auditor or other advisors or consultants (and any such opinions or advice which are in writing shall be attached to the statement). If the Executive objects to
the Company’s calculations, the Company shall pay to the Executive such portion of the Severance Payments (up to 100% thereof) as the Executive determines is necessary to result in the proper application of subsection A of this Section 6.2.

  
 6.3 The payments provided in subsections (A), (C) and (D) of
Section 6.1 hereof shall be made not later than the fifth day following the Date of Termination; provided, however, that if the amounts of such payments, and the limitation on such payments set forth in Section 6.2 hereof, cannot be
finally determined on or before such day, the Company shall pay to the Executive on such day an estimate, as determined in good faith by the Executive of the minimum amount of such payments to which the Executive is clearly entitled and shall pay
the remainder of such payments (together with interest on the unpaid remainder (or on all such payments to the extent the Company fails to make such payments when due) at 120% of the rate provided in Section 1274(b)(2)(B) of the Code) as soon as the
amount thereof can be determined but in no event later than the thirtieth (30th) day after the Date of Termination. In the event that the amount of the estimated payments exceeds the amount subsequently determined to have been due, such excess shall
constitute a loan by the Company to the Executive, payable on the fifth (5th) business day after demand by the Company (together with interest at 120% of the rate provided in Section 1274(b)(2)(B) of the Code). 
  
 6.4 The Company also shall pay to the Executive all legal fees and expenses
incurred by the Executive in disputing in good faith any issue hereunder relating to the termination of the Executive’s employment, in seeking in good faith to obtain or enforce any benefit or right provided by this Agreement or in connection
with any tax audit or proceeding to the extent attributable to the application of Section 4999 of the Code to any payment or benefit provided hereunder. Such payments shall be made within five (5) business days after delivery of the Executive’s
written requests for payment accompanied with such evidence of fees and expenses incurred as the Company reasonably may require. 
  

 7 

 6.5 Notwithstanding any other provision of this agreement, if the executive is entitled to and claims
benefits under or pursuant to any other change in control agreement entered into between Company or Sierra and the executive, or any terms or conditions thereunder, the executive shall not be entitled to any of the severance benefits or any other
benefits under this agreement or terms or conditions of this agreement. 
  
 7. Termination Procedures and Compensation During Dispute. 
  
 7.1 Notice of Termination. After a Change in Control or potential Change in Control and during the Term, any purported termination of the Executive’s employment (other than by reason of death) shall be
communicated by written Notice of Termination from one party hereto to the other party hereto in accordance with Section 10 hereof. For purposes of this Agreement, a “Notice of Termination” shall mean a notice which shall indicate the
specific termination provision in this Agreement relied upon and shall set forth in reasonable detail the facts and circumstances claimed to provide a basis for termination of the Executive’s employment under the provision so indicated.
Further, a Notice of Termination for Cause is required to include a copy of a resolution duly adopted by the affirmative vote of not less than three-quarters (3/4) of the entire membership of the Board at a meeting of the Board which was called and
held for the purpose of considering such termination (after reasonable notice to the Executive and an opportunity for the Executive, together with the Executive’s counsel, to be heard before the Board) finding that, in the good faith opinion of
the Board, the Executive was guilty of conduct set forth in clause (i) or (ii) of the definition of Cause herein, and specifying the particulars thereof in detail. 
  
 7.2 Date of Termination. “Date of Termination,” with respect to any purported termination of the
Executive’s employment after a Change in Control or potential Change in Control and during the Term, shall mean (i) if the Executive’s employment is terminated for Disability, thirty (30) days after Notice of Termination is given (provided
that the Executive shall not have returned to the full-time performance of the Executive’s duties during such thirty (30) day period), and (ii) if the Executive’s employment is terminated for any other reason, the date specified in the
Notice of Termination (which, in the case of a termination by Sierra, shall not be less than thirty (30) days (except in the case of a termination for Cause) and, in the case of a termination by the Executive, shall not be less than fifteen (15)
days nor more than sixty (60) days, respectively, from the date such Notice of Termination is given). 
  
 7.3 Dispute Concerning Termination. If within fifteen (15) days after any Notice of Termination is given, or, if later, prior to the Date of
Termination (as determined without regard to this Section 7.3), the party receiving such Notice of Termination notifies the other party that a dispute exists concerning the termination, the Date of Termination shall be extended until the earlier of
(i) the date on which the Term ends or (ii) the date on which the dispute is finally resolved, either by 
  

 8 

 mutual written agreement of the parties or by a final judgment, order or decree of an arbitrator or a court of competent
jurisdiction (which is not appealable or with respect to which the time for appeal therefrom has expired and no appeal has been perfected); provided, however, that the Date of Termination shall be extended by a notice of dispute given
by the Executive only if such notice is given in good faith and the Executive pursues the resolution of such dispute with reasonable diligence. 
  
 7.4 Compensation During Dispute. If a purported termination occurs following a Change in Control or potential Change in Control and during the Term
and the Date of Termination is extended in accordance with Section 7.3 hereof, the Company shall continue to pay the Executive the full compensation in effect when the notice giving rise to the dispute was given (including, but not limited to,
salary) and continue the Executive as a participant in all compensation, benefit and insurance plans in which the Executive was participating when the notice giving rise to the dispute was given, until the Date of Termination, as determined in
accordance with Section 7.3 hereof. Amounts paid under this Section 7.4 are in addition to all other amounts due under this Agreement (other than those due under Section 5.2 hereof) and shall not be offset against or reduce any other amounts due
under this Agreement. 
  
 8. No Mitigation. The Company
agrees that, if the Executive’s employment with Sierra terminates during the Term, the Executive is not required to seek other employment or to attempt in any way to reduce any amounts payable to the Executive by the Company pursuant to Section
6 hereof or Section 7.4 hereof. Further, the amount of any payment or benefit provided for in this Agreement (other than Section 6.1(B) hereof) shall not be reduced by any compensation earned by the Executive as the result of employment by another
employer, by retirement benefits, by offset against any amount claimed to be owed by the Executive to the Company, or otherwise. 
  
 9. Successors; Binding Agreement. 
  
 9.1 In addition to any obligations imposed by law upon any successor to the Company, the Company will require any successor (whether direct or indirect,
by purchase, merger, consolidation or otherwise) to all or substantially all of the business and/or assets of the Company to expressly assume and agree to perform this Agreement in the same manner and to the same extent that the Company would be
required to perform it if no such succession had taken place. Failure of the Company to obtain such assumption and agreement prior to the effectiveness of any such succession shall be a breach of this Agreement and shall entitle the Executive to
compensation from the Company in the same amount and on the same terms as the Executive would be entitled to hereunder if the Executive were to terminate the Executive’s employment for Good Reason after a Change in Control, except that, for
purposes of implementing the foregoing, the date on which any such succession becomes effective shall be deemed the Date of Termination. 
  

 9 

 9.2 This Agreement shall inure to the benefit of and be enforceable by the Executive’s personal or
legal representatives, executors, administrators, successors, heirs, distributees, devisees and legatees. If the Executive shall die while any amount would still be payable to the Executive hereunder (other than amounts which, by their terms,
terminate upon the death of the Executive) if the Executive had continued to live, all such amounts, unless otherwise provided herein, shall be paid in accordance with the terms of this Agreement to the executors, personal representatives or
administrators of the Executive’s estate. 
  
 10.
Notices. For the purpose of this Agreement, notices and all other communications provided for in the Agreement shall be in writing and shall be deemed to have been duly given when delivered or mailed by United States registered mail, return
receipt requested, postage prepaid, addressed, if to the Executive, to the address inserted below the Executive’s signature on the final page hereof and, if to the Company, to the address set forth below, or to such other address as either
party may have furnished to the other in writing in accordance herewith, except that notice of change of address shall be effective only upon actual receipt: 
  

To the Company:

 6100 Neil Road 
 Reno, Nevada 89520-3150 
 Attention:  General Counsel 
  
 11. Miscellaneous. No provision of this Agreement may be modified, waived or discharged unless such waiver, modification or discharge is agreed to
in writing and signed by the Executive and such officer as may be specifically designated by the Board. No waiver by either party hereto at any time of any breach by the other party hereto of, or of any lack of compliance with, any condition or
provision of this Agreement to be performed by such other party shall be deemed a waiver of similar or dissimilar provisions or conditions at the same or at any prior or subsequent time. This Agreement supersedes any other agreements or
representations, oral or otherwise, express or implied, with respect to the subject matter hereof which have been made by either party; provided, however, that this Agreement shall supersede any agreement setting forth the terms and
conditions of the Executive’s employment with Sierra only in the event that the Executive’s employment with Sierra is terminated on or following a Change in Control or potential Change in Control, by Sierra other than for Cause or by the
Executive other than for Good Reason. The validity, interpretation, construction and performance of this Agreement shall be governed by the laws of the State of Nevada. All references to sections of the Exchange Act or the Code shall be deemed also
to refer to any successor provisions to such sections. Any payments provided for hereunder shall be paid net of any applicable withholding required under federal, state or local law and any additional withholding to which the 
  

 10 

 Executive has agreed. The obligations of the Company and the Executive under this Agreement which by their nature may
require either partial or total performance after the expiration of the Term (including, without limitation, those under Sections 6 and 7 hereof) shall survive such expiration. 
  
 12. Validity. 
  
 12.1 The invalidity or unenforceability of any provision of this Agreement shall not affect the validity or enforceability of any other provision of this
Agreement, which shall remain in full force and effect. 
  
 13.
Counterparts. This Agreement may be executed in several counterparts, each of which shall be deemed to be an original but all of which together will constitute one and the same instrument. 
  
 14. Settlement of Dispute; Arbitration. 
  
 14.1 All claims by the Executive for benefits under this Agreement shall be
directed to and determined by the Board and shall be in writing. Any denial by the Board of a claim for benefits under this Agreement shall be delivered to the Executive in writing and shall set forth the specific reasons for the denial and the
specific provisions of this Agreement relied upon. The Board shall afford a reasonable opportunity to the Executive for a review of the decision denying a claim and shall further allow the Executive to appeal to the Board a decision of the Board
within sixty (60) days after notification by the Board that the Executive’s claim has been denied. 
  
 14.2 Any further dispute or controversy arising under or in connection with this Agreement shall be settled exclusively by arbitration in Reno, Nevada in
accordance with the rules of the American Arbitration Association then in effect; provided, however, that the evidentiary standards set forth in this Agreement shall apply. Judgment may be entered on the arbitrator’s award in any
court having jurisdiction. Notwithstanding any provision of this Agreement to the contrary, the Executive shall be entitled to seek specific performance of the Executive’s right to be paid until the Date of Termination during the pendency of
any dispute or controversy arising under or in connection with this Agreement. 
  
 15. Definitions. For purposes of this Agreement, the following terms shall have the meanings indicated below:

hereof. 
  

 11 

 (C) “Base Amount” shall have the meaning set forth in Section 280G(b)(3) of the Code.

written demand for substantial performance is delivered to the Executive by the Board, which demand specifically identifies the manner in which the Board believes that the Executive has not substantially performed the Executive’s duties, or
(ii) the willful engaging by the Executive in conduct which is demonstrably and materially injurious to Sierra, monetarily or otherwise. For purposes of clauses (i) and (ii) of this definition, (x) no act, or failure to act, on the Executive’s

 12 

 recommended by a vote of at least two-thirds (2/3) of the directors then still in office who either were
directors on the date hereof or whose appointment, election or nomination for election was previously so approved or recommended; or 
  
 (III) there is consummated a merger or consolidation of the Company or any direct or indirect subsidiary of the Company with any other
corporation, other than (i) a merger or consolidation which would result in the voting securities of the Company outstanding immediately prior to such merger or consolidation continuing to represent (either by remaining outstanding or by being
converted into voting securities of the surviving entity or any parent thereof), in combination with the ownership of any trustee or other fiduciary holding securities under an employee benefit plan of the Company or any subsidiary of the Company,
at least 66.66% of the combined voting power of the securities of the Company or such surviving entity or any parent thereof outstanding immediately after such merger or consolidation, or (ii) a merger or consolidation effected to implement a

	10.	UNCONTROLLABLE FORCES: 

  
 No Party shall be considered to be in breach of this Agreement or any applicable Confirmation Agreement to the extent that a failure to
perform its obligations under this Agreement or any such Confirmation Agreement shall be due to an Uncontrollable Force. The term “Uncontrollable Force” means an event or circumstance which prevents one Party from performing its
obligations under one or more transactions, which event or circumstance is not within the reasonable control of, or the result of the negligence of the claiming Party, and which by the exercise of due diligence, the claiming Party is unable to
avoid, cause to be avoided, or overcome. So long as the requirements of the preceding sentence are met, “Uncontrollable Forces” may include and are not restricted to flood, drought, earthquake, storm, fire, lightning, epidemic, war, riot,
civil disturbance or disobedience, labor dispute, labor or material shortage, sabotage, restraint by court order or public authority, and action or nonaction by, or failure to obtain the necessary authorizations or approvals from, any governmental
agency or authority.

 Party to settle any strike or labor dispute in which it may be involved. Any Party rendered unable to
fulfill any of its obligations by reason of an Uncontrollable Force shall give prompt notice of such fact and shall exercise due diligence, as provided above, to remove such inability within a reasonable time period. If oral notice is provided, it
shall be promptly followed by written notice. 
  
 Notwithstanding the “due diligence” obligations or obligations to remove or remedy the causes set forth in the foregoing paragraph (which do not apply to this paragraph except as specified below), where the entity providing
transmission services for transactions under any Service Schedule interrupts such transmission service, the interruption in transmission service shall be considered an Uncontrollable Force under this Section 10 only in the following two sets of
circumstances: 
  

	 	(1)	An interruption in transmission service shall be considered an Uncontrollable Force if (a) the Parties agreed on a transmission path for that transaction at the time the transaction
under this Agreement was entered into by the Parties’ thereto, (b) firm transmission involving that transmission path was obtained pursuant to a transmission tariff or contract to effectuate the transaction under the applicable Service
Schedule, and (c) the entity providing transmission service curtailed or interrupted such firm transmission pursuant to the applicable transmission tariff or contract; 

  

	 	(2)	if the Parties did not agree on the transmission path for a transaction at the time the transaction was entered into, an interruption in transmission service shall be

have made arrangements with the entity providing transmission service for firm transmission to effectuate the transaction under the applicable Service Schedule, (b) the entity providing transmission service curtailed or interrupted such transmission
service due to an event of Uncontrollable Forces or provision of like effect, and (c) the Party which contracted for such firm transmission services could not obtain alternate energy at the delivery point, alternate transmission services, or
alternate means of delivering energy after exercising due diligence. 
  
 No Party shall be relieved by operation of this Section 10 of any liability to pay for power delivered to the Purchaser or to make payments then due or which the Party is obligated to make with respect to performance
which occurred prior to the Uncontrollable Force. 
  

	11.	WAIVERS: 

  
 Any waiver at any time by any Party of its rights with respect to a default under this Agreement or any Confirmation Agreements, or any
other matter under this Agreement, shall not be deemed a waiver with respect to any subsequent default of the same or any other matter.

Electric Power Planning and Conservation Act, 16 U.S.C. Sec. 839e, provided such rates do not exceed the maximum rates in the applicable Service Schedule and are consistent with the terms and conditions of said Service Schedule. If, upon filing of
this Agreement by Parties subject to FERC jurisdiction under the Federal Power Act, FERC orders a hearing to determine whether this Agreement or a Service Schedule under this Agreement is just and reasonable under the Federal Power Act, the
Agreement or Service Schedule shall not become effective until the date when an order issued by FERC, determining this Agreement or the Service Schedule to be just and reasonable without changes or new conditions unacceptable to the Parties, is no
longer subject to judicial review. Any changes or conditions imposed by any agency or court, including FERC ordering a hearing, shall be cause for immediate withdrawal by any nonconsenting Party.

 No Party shall voluntarily transfer its membership under this Agreement without the written consent and approval of all other Parties
except to a Successor in Operation of such Party. With regard to the transfer of the rights and obligations of any Party associated with transactions under the Service Schedules, neither Party may assign such rights or obligations unless (a) the
other Party provides its prior written consent which shall not be unreasonably withheld; or (b) the assignment is to a Successor in Operation which provides reasonable creditworthiness assurances (see Section 27 for examples of such assurances) if
required by the non-assigning Party based upon its reasonably exercised discretion. Any successor or assignee of the rights of any Party, whether by voluntary transfer, judicial or foreclosure sale or otherwise, shall be subject to all the
provisions and conditions of this Agreement and Confirmation Agreements (where applicable) to the same extent as though such successor or assignee were the original Party under this Agreement or the Confirmation Agreements, and no assignment or
transfer of any rights under this Agreement or any Confirmation Agreement shall be effective unless and until the assignee or transferee agrees in writing to assume all of the obligations of the assignor or transferor and to be bound by all of the

 In the event that any of the terms, covenants or conditions of this Agreement or any Confirmation Agreement, or the application of any
such term, covenant or condition, shall be held invalid as to any person or circumstance by any court, regulatory agency, or other regulatory body having jurisdiction, all other terms, covenants or conditions of this Agreement and the Confirmation

WSPP’s attorneys or consultants with regard to their work for the WSPP, provided that the foregoing prohibition shall not apply in proceedings brought against the WSPP. In the event a Party seeks to compel discovery or testimony in violation of
this Section, that Party shall be deemed to have consented to the quashing of the subpoena or other process providing therefor. Notwithstanding any other provision in this Agreement, a Party that seeks to conduct discovery or take testimony in
breach of this provision shall compensate the WSPP and its officers, attorneys, and consultants, as applicable, for all out-of-pocket costs incurred.

reduction in the Purchaser’s schedule or receipt of electric energy (based on Seller’s reasonable commercial efforts to achieve such reduction). If the total amounts for all hours calculated under this paragraph (1) are negative, then
neither the Purchaser nor the Seller shall pay any amount under this Section 21.3(a)(1).

 If an Event of Default occurs, the Non-Defaulting Party shall possess the right to terminate all transactions between the Parties under
this Agreement upon written notice (by facsimile or other reasonable means) to the Defaulting Party, such notice of termination to be effective immediately upon receipt. If the Non- Defaulting Party fails to exercise this right of termination within
thirty (30) days following the time when the Event of Default becomes known (or more than thirty days if the Non-Defaulting and Defaulting Parties agree to an extension), then such right of termination shall no longer be available to the
Non-Defaulting Party as a remedy for the Event(s) of Default; provided, however, this thirty day requirement for exercising termination rights shall not apply to defaults pursuant to Sections 22.1(c) and 22.1(e)(iii). The Non-Defaulting Party
terminating transaction(s) under this Section 22.2 may do so without making a filing at FERC. Upon termination, the Non-Defaulting Party shall liquidate all transactions as soon as practicable, provided that in no event will the Non-Defaulting Party
be allowed to liquidate Service Schedule A transactions. The payment associated with termination (“Termination Payment”) shall be calculated in accordance with

 of such notice of termination by the Defaulting Party, the Non-Defaulting Party may exercise any
remedies available to it under Section 21.3 of this Agreement or Confirmation Agreement(s), and any other remedies available to it at law or otherwise. 
  
 Upon termination, the Non-Defaulting Party may withhold any payments it owes the Defaulting Party for any obligations incurred prior to
termination under this Agreement or Confirmation Agreement(s) until the Defaulting Party pays the Termination Payment to the Non-Defaulting Party. The Non-Defaulting Party shall possess the right to set-off the amount due it under this Section 22 by
any such payments due the Defaulting Party as provided in Section 22.3(d). 
  

	 	22.3	LIQUIDATION CALCULATION OPTIONS 

  
 The Non-Defaulting Party shall calculate the Termination Payment as follows: 
  

	 	(a)	The Gains and Losses shall be determined by comparing the value of the remaining term, transaction quantities, and transaction prices under each Terminated Transaction had it not
been terminated to the equivalent quantities and relevant market prices for the remaining term either quoted by a bona fide third-party offer or which are reasonably expected to be available in the market under a replacement contract for each
Terminated Transaction. To ascertain the market prices of a replacement contract, the Non-Defaulting Party may consider, among other valuations, quotations

 from Dealers in energy contracts, any or all of the settlement prices of the NYMEX power futures
contracts (or NYMEX power options contracts in the case of Physically-Settled Options) and other bona fide third party offers, all adjusted for the length of the remaining term and differences in transmission. It is expressly agreed that the
Non-Defaulting Party shall not be required to enter into replacement transactions in order to determine the Termination Payment. 
  

	 	(b)	The Gains and Losses calculated under paragraph (a) shall be discounted to present value using the Present Value Rate as of the time of termination (to take account to the period
between the time notice of termination was effective and when such amount would have otherwise been due pursuant to the relevant transaction). The “Present Value Rate” shall mean the sum of 0.50% plus the yield reported on page
“USD” of the Bloomberg Financial Markets Services Screen (or, if not available, any other nationally recognized trading screen reporting on-line intraday trading in United States government securities) at 11:00 a.m. (New York City, New
York time) for the United States government securities having a maturity that matches the average remaining term of the Terminated Transactions; and 

  

	 	(c)	The Non-Defaulting Party shall set off or aggregate, as appropriate, the Gains and Losses (as calculated in Section 22.3(a)) and Costs and notify

 the Defaulting Party. If the Non-Defaulting Party’s aggregate Losses and Costs exceed its
aggregate Gains, the Defaulting Party shall, within three (3) Business Days of receipt of such notice, pay the Termination Payment to the Non-Defaulting Party, which amount shall bear interest at the Present Value rate from the time notice of
termination was received until paid. If the Non-Defaulting Party’s aggregate Gains exceed its aggregate Losses and Costs, the Non-Defaulting Party, after any set-off as provided in paragraph (d), shall pay the remaining amount to the Defaulting
Party within three (3) Business Days of the date notice of termination was received including interest at the Present Value from the time notice of termination was received until the Defaulting Party receives payment. 
  

	 	(d)	The Non-Defaulting Party shall aggregate or set off, as appropriate, at its election, any or all other amounts owing between the Parties (discounted at the Present Value Rate) under
this Agreement and any Confirmation Agreements against the Termination Payment so that all such amounts are aggregated and/or netted to a single liquidated amount. The net amount due from any such liquidation shall be paid within three (3) Business
Days following the date notice of termination is received.

 Party may elect to pay the Defaulting Party the monies owed under this Section 22.3 over the
remaining life of the contract(s) being terminated. The Non-Defaulting Party may make this election by providing written notice to the Defaulting Party within three Business Days of the notice being provided to terminate and liquidate under this
Section 22.3. The Non-Defaulting Party shall provide the Defaulting Party with the details on the method for recovering the monies owed over the remaining life of the contract(s). That method shall ensure that the Defaulting Party receives a payment
each month through the end of the term of each contract which allows it to receive the monies which would have been due it under Sections 22.3(c) and (d) in total (to be recovered over the term of the contract(s) to replicate as closely as possible
the payment streams under such contract(s)) provided that the discounting using the Present Value Rate referenced in Section 22.3 (b) shall not be reflected in determining the amounts to be recovered under this provision. Any disputes as to the
methodology shall be resolved pursuant to the dispute resolution procedures in Section 34, with binding arbitration pursuant to Section 34.2 required for disputes as to the methodology if mediation is unsuccessful.

	 	(iv)	If the Party owing money defaults on its payment obligations consistent with Section 22.1(a) or defaults with regard to providing credit assurances consistent with Section 22.1(d),
then the other Party shall have the right (by written notice) at any time after the Party owing money defaults to require that Party to pay all monies owed under all of the contracts subject to this Section 22.3(e) within three Business Days of
receipt of the written notice. The monies to be paid under this accelerated payment provision shall be the remaining amounts to be paid under the contract(s) reflecting a discount using the Present Value Rate from the date of the written notice.

OPERATING COSTS: 

  

	 	22A.1	A Party shall be deemed to be in default in payment of its share of WSPP operating costs pursuant to Section 7 of this Agreement, if any, when payment is not received within ten
(10) days after receipt of written notice. A default by any Party in such payment obligations shall be cured by payment of all overdue amounts together with interest accrued at the rate of one percent (1%) per month, or the maximum interest rate
permitted by law, if any, whichever is less, prorated by days from the due date to the date the payment curing the default is made unless and until the Executive Committee shall determine another rate.

 Parties’ representatives on the Executive Committee consistent with Section 8.3. The defaulting
Party’s rights shall not be revoked, however, unless said Party has received at least thirty (30) days written notice of the non-defaulting Parties’ intent to revoke such rights. Said notice shall state the date on which the revocation of
rights shall become effective if the default is not cured and shall state all actions which must be taken or amounts which must be paid to cure the default. This provision allowing the non-defaulting Parties to revoke such rights is in addition to
any other remedies provided in this Agreement or at law and shall in no way limit the non-defaulting Parties’ ability to seek judicial enforcement of the defaulting Party’s obligations to pay its share of the operating costs under this
Agreement. Upon the effective date of such revocation of rights, the defaulting party shall not be allowed to enter into any new transactions under this Agreement. The defaulting party under the Agreement or any Confirmation Agreements shall be
required to carry out all obligations that existed prior to the effective date of such revocation. If a defaulting Party’s rights under this Agreement have been revoked, the Executive Committee may restore that Party’s rights upon the
defaulting Party paying all amounts due and owing under this Agreement.

such other Party’s reasonably exercised discretion with regard to any transaction pursuant to this Agreement or any Confirmation Agreement, the dissatisfied Party (the “First Party”) may require the other Party (the “Second
Party”) to provide, at the Second Party’s option (but subject to the First Party’s acceptance based upon reasonably exercised discretion), either (1) the posting of a Letter of Credit, (2) a cash prepayment, (3) the posting of other
acceptable collateral or security by the Second Party, (4) a Guarantee Agreement executed by a creditworthy entity; or (5) some other mutually agreeable method of satisfying the First Party. The Second Party’s obligations under this Section 27
shall be limited to a reasonable estimate of the damages to the First Party

 (consistent with Section 22.3 of this Agreement) if the Second Party were to fail to perform its
obligations. Events which may trigger the First Party questioning the Second Party’s creditworthiness, financial responsibility, or performance viability include, but are not limited to, the following: 
  

	 	(1)	The First Party has knowledge that the Second Party (or its Guarantor if applicable) are failing to perform or defaulting under other contracts. 

  

	 	(2)	The Second Party has exceeded any credit or trading limit set out in the Confirmation Agreement or other agreement between the Parties. 

  

	 	(3)	The Second Party or its Guarantor has debt which is rated as investment grade and that debt falls below the investment grade rating by at least one rating agency or is below
investment grade and the rating of that debt is downgraded further by at least one rating agency. 

  

	 	(4)	Other material adverse changes in the Second Party’s financial condition occur. 

  

	 	(5)	Substantial changes in market prices which materially and adversely impact the Second Party’s ability to perform under this Agreement or any Confirmation Agreement occur.

  
 If the Second Party fails to
provide such reasonably satisfactory assurances of its ability to perform a transaction hereunder within three (3) Business Days of demand therefore, that will be considered an Event of Default under Section 22 of this Agreement and the First Party
shall have the right to exercise any of the remedies provided for under that Section 22. Nothing contained in this Section 27 shall affect any credit agreement or arrangement, if any, between the Parties.

	 	28.1	If the Purchaser and the Seller are each required to pay an amount to each other in the same calendar month for transactions under this Agreement, then such amounts with respect to
each Party may be aggregated and the Parties may discharge their obligations to pay through netting of the respective amounts due, in which case the Party, if any, owing the greater aggregate amount may pay to the other Party the difference between
the amounts owed. Each Party reserves to itself all rights, set-offs, counterclaims, and other remedies and defenses (to the extent not expressly herein waived or denied) which such Party has or may be entitled to arising from or out of this
Agreement and any applicable Confirmation Agreements.

Party shall provide at least 30 days notice on the WSPP Homepage of the change in its election to net and also shall provide, concurrent with its withdrawal notice, written notice to all Parties with which it has ongoing transactions or with which
it has committed to future transactions under the Agreement at the time of the notice. Any such changes in netting status shall apply beginning at least 30 days after notice required by this Section 28.2 is provided and only shall apply to
transactions agreed to beginning on or after the date the change in netting status becomes effective.

including Sections 7 and 8), such agreement to be reflected in a Confirmation Agreement. Written confirmation shall be required for all transactions of one week or more. Upon request of the Purchaser or at the election of the Seller, the Seller
shall provide written confirmation which must be received by the Purchaser within five Business Days of the date of the agreement or request. The Purchaser shall have five Business Days from date of receipt to respond to the confirmation. If the
Purchaser does not respond within that time period, the Seller’s written confirmation shall be considered as accepted and final except as provided in Section 32.5. If the Seller fails to provide any required written confirmation within five
Business Days, as described above, then the Purchaser may submit a written confirmation to the Seller. The Purchaser shall submit such written confirmation within five Business Days after the deadline for submitting a written confirmation applicable
to the Seller as set forth above has expired. If the Seller fails to respond to Purchaser’s confirmation within five Business Days, then the Purchaser’s written confirmation shall be considered as accepted and final except as provided in
Section 32.5. Notwithstanding the foregoing, any failure of the Seller or the Purchaser to provide written confirmation of the transaction shall not invalidate any oral agreement of the Parties except for oral agreements prohibited by Section 32.5.
Nor shall any oral agreement of the Parties be considered invalidated

basis that documentation of such terms fails to comply with the requirements of any statute that agreements be written or signed. Each Party consents to the recording by the other Party, without any further notice, of telephone conversations between
representatives of the Parties, which contain agreements to or discussion concerning the terms of a specific transaction(s). All such recordings may be introduced and admitted into evidence for the purpose of proving agreements to terms, and any
objection to such introduction or admission for such purpose is hereby expressly waived. The terms documented hereunder, whether stated in a written document or a recording, are intended by the Parties as a final expression of their agreement with
respect to such terms as are included therein and may not be contradicted by evidence of any prior agreement, but may be supplemented by course of dealing, performance, usage of trade and evidence of consistent additional mutually agreed-upon terms.

  

	 	32.3	For individual transactions under the Service Schedules, the Agreement as it may be modified or supplemented by a Confirmation Agreement shall bind the Parties and govern the

Non-Standard Confirmation Provisions shall not be deemed to be accepted pursuant to Section 32.1 unless agreed to: (i) orally, with that oral agreement recorded (provided that such oral agreement option only shall be available for transactions of
less than one week); or (ii) in a writing executed by both Parties. 

  

	 	32.6	Other Products and Service Levels: The Parties may agree to use a product/service level defined by a different agreement (e.g., the California ISO tariff, the ERCOT agreement or the
EEI agreement) for a particular transaction under this Agreement. Unless the Parties expressly state and agree that all the terms and conditions of such other agreement will apply to any such transaction, the transaction shall be subject to all the
terms of this Agreement, except that (1) all service level/product definitions, (2) force majeure/uncontrollable force definitions, and (3) other terms as mutually agreed shall have the meaning ascribed to them in the different agreement or in the
applicable confirmation notice or agreement

Party or the subject matter of the mediation. The WSPP shall establish procedures for the appointment of mediators and the conduct of mediation and those procedures shall apply to the mediation. 
  

	 	34.2	BINDING DISPUTE RESOLUTION 

  
 The Parties to a dispute may elect binding dispute resolution using the following process unless binding arbitration of certain disputes
is required under this Agreement in which event the Parties shall use the process set forth in this Section 34.2 to resolve such disputes, unless the Parties otherwise agree: 
  

	 	(a)	WSPP Dispute Resolution: A Party to a dispute (if binding dispute resolution is required) or all Parties to a dispute (if agreement of the Parties is required for binding dispute
resolution) may initiate binding dispute resolution under WSPP procedures by notifying the Chairman of the WSPP Operating Committee or his or her designee. The Chairman or his or her designee shall provide the Parties with a list of ten (10)
eligible arbitrators. Within ten (10) days of receiving the list, the Parties shall agree on a single arbitrator from the list to conduct the arbitration, or notify the Chairman of the Operating Committee or the designee of their inability to reach
agreement. If notified of the Parties inability to reach agreement, then the Chairman or the designee shall choose the arbitrator from the list within five (5) days. Neither the arbitrator nor the person

procedures which shall be developed and maintained by the WSPP and the procedures will be generally consistent with the commercial arbitration rules of the American Arbitration Association though not involving the Association. 
  
 If the Parties agree to binding dispute resolution under
this Section 34.2, each Party understands that it will not be able to bring a lawsuit concerning any dispute that may arise which is covered by this arbitration provision. Notwithstanding the foregoing, nothing herein is intended to waive any
provision of the Federal Arbitration Act, 9 U.S.C. § 1, et. seq., or any right under state statute or common law to challenge an arbitration award or to prevent any action to enforce any arbitration award. 
  
 A Party’s liability and damages under any arbitration
award resulting from the process set forth in this Section 34.2 shall be limited as provided in this Agreement or in any Confirmation Agreement.

	 	38.1	In the event the Parties intend that the price for a transaction is to be based on an index, exchange or any other kind of variable reference price (such price being a
“Floating Price”), the Parties shall specify the “Floating Price” to be used to calculate the amounts in a Confirmation Agreement due Seller for that transaction. 

  

	 	38.2	Market Disruption. If a Market Disruption Event has occurred and is continuing during the Determination Period, the Floating Price for the affected Trading Day shall be determined
as follows. The Parties shall negotiate in good faith to agree on a Floating Price (or a method for determining a Floating Price) for the affected Trading Day. If the Parties have not so agreed on or before the twelfth Business Day following the
first Trading Day on which the Market Disruption Event occurred or existed, then the Floating Price shall be determined in good faith by the Parties based upon (1) quotes from Dealers in energy contracts; and/or (2) quotes from Brokers in energy
contracts. Each Party may obtain up to a maximum of four quotes which must be provided to the other Party no later than twenty-two Business Days following the first Business Day on which the Market Disruption Event occurred or existed. These quotes
shall reflect transacted prices. The Floating Price for the affected Trading Day shall equal a simple average of the quotes obtained and provided by the Parties consistent with the provisions of this Section 38. Each Party providing quote(s) to the
other Party also shall identify to that other Party the Dealer(s) and/or the Broker(s) who provided each of the quotes to allow verification

 “Determination Period” means each calendar month during the term of the relevant
transaction; provided that if the term of the transaction is less than one calendar month the Determination Period shall be the term of the transaction. “Market Disruption Event” means, with respect to an index, any of the following events
(the existence of which shall be determined in good faith by the Parties): (a) the failure of the index to announce or publish information necessary for determining the Floating Price; (b) the failure of trading to commence or the permanent
discontinuation or material suspension of trading in the relevant options contract or commodity on the exchange or market acting as the index; (c) the temporary or permanent discontinuance or unavailability of the index; (d) the temporary or
permanent closing of any exchange acting as the index; or (e) a material change in the formula for or the method of determining the Floating Price. 
  
 “Trading Day” means a day in respect of which the relevant price source published the relevant price or would have published the relevant price
but for the Market Disruption Event. 
  

	 	38.3	Calculation of Floating Price. For the purposes of the calculation of a Floating Price, all numbers shall be rounded to three (3) decimal places. If the fourth (4th) decimal number
is five (5) or greater, then the third (3rd) decimal number shall be increased by one (1), and if the fourth (4th) decimal number is less than five (5), then the third (3rd) decimal number shall remain unchanged.

price is subsequently corrected and the correction is published or announced by the person responsible for that publication or announcement, either Party may notify the other Party of (i) that correction and (ii) the amount (if any) that is payable
as a result of that correction. If a Party gives notice that an amount is so payable, the Party that originally either received or retained such amount will pay such amount consistent with the provisions of this Section 38.4. The amount that is

 If the Purchaser and Seller are each required to pay an amount on the
payment due date in the same month for transactions under the Agreement or Confirmation Agreement, then such amounts with respect to each Party will be aggregated and the Parties will discharge their obligations to pay through netting, in which case
the Party owing the greater aggregate amount will pay to the other party the difference between the amounts owed consistent with the payment times in Section 9.2 of the Agreement, unless the Parties have otherwise agreed to a different payment time
as allowed by the Agreement. Each Party reserves to itself all rights, set-offs, counterclaims and other remedies and/or defenses to which it is or may be entitled, arising from or out of the Agreement. All outstanding payments between the Parties
which are to be netted pursuant to this Exhibit A for transactions under WSPP Service Schedule A, B, and C shall be offset against each other or set off or recouped therefrom.

 WITNESSETH: 
  
 WHEREAS, [                    ] (the
