 ARTICLE II 
 THE CREDITS 
 Section 2.01 Commitments. 
 (a) Subject to the terms and conditions and relying upon the representations and warranties herein set forth, each Bank agrees, severally
and not jointly, to make Loans to the Borrower, at any time and from time to time during the Availability Period, in an aggregate principal amount at any time outstanding that will not result in (a) the Revolving Credit Exposure of any Bank
exceeding such Bank’s Commitment or (b) the total Revolving Credit Exposures exceeding the total Commitments. Within the limits set forth in the preceding sentence, the Borrower may borrow, pay or prepay, and reborrow Loans during the
Availability Period, subject to the terms, conditions and limitations set forth herein. 
 Section 2.02 Loans. 
 (a) Each Loan shall be made as part of a Borrowing consisting of Loans made by the Banks ratably in accordance with their Commitments. The
failure of any Bank to make any Loan required to be made hereunder shall not in itself relieve any other Bank of its obligation to lend hereunder (it being understood, however, that no Bank shall be responsible for the failure of any other Bank to
make any Loan required to be made by such other Bank). The Loans comprising each Borrowing shall be in the aggregate principal amount of $1,000,000 or a whole-integer multiple of $100,000 in excess thereof. 
 (b) Subject to Section 2.08, each Borrowing shall be comprised entirely of ABR Loans or Eurodollar Loans, as the Borrower may request
pursuant to Section 2.03. Each Bank may at its option fulfill its Commitment with respect to any Eurodollar Loan by causing any domestic or foreign branch or Affiliate of such Bank to make such Loan; provided that any exercise of such
option shall not affect the obligation of the Borrower to repay such Loan in accordance with the terms of this Agreement or any applicable Note. Borrowings of more than one Type may be outstanding at the same time; provided, however,
that the Borrower shall not be entitled to request any Borrowing which, if made, would result in an aggregate of more than eight separate Eurodollar Loans of any Bank being outstanding hereunder at any one time. For purposes of the foregoing, Loans
having different Interest Periods, regardless of whether they commence on the same date, shall be considered separate Loans. 
 (c) Subject to paragraph (e) below, each Bank shall make a Loan in the amount of its Pro Rata Share of each Borrowing on the proposed date thereof by wire transfer of immediately available funds to the Administrative Agent in Los
Angeles, California, not later than 11:00 a.m., Pacific time, and the Administrative Agent shall by 1:00 p.m., Pacific time, make available to the Borrower in immediately available funds the amounts so received (i) by wire transfer for credit
to the account of the Borrower with Wells Fargo Bank, National Association bearing Account Number 41688 14770; ABA # 121000248, re: Avista Corp. or (ii) as otherwise specified by the Borrower in its notice of Borrowing or, if a Borrowing shall
not occur on such date because any condition precedent herein specified shall not have been met, return the amounts so received to the respective Banks. Unless the Administrative Agent shall 

  

 17 








 
have received notice from a Bank prior to the date of any Borrowing that such Bank will not make available to the Administrative Agent such Bank’s
portion of such Borrowing, the Administrative Agent may assume that such Bank has made such portion available to the Administrative Agent on the date of such Borrowing in accordance with this paragraph (c) and the Administrative Agent may, in
reliance upon such assumption, make available to the Borrower on such date a corresponding amount. If and to the extent that such Bank shall not have made such portion available to the Administrative Agent, such Bank and the Borrower severally agree
to repay to the Administrative Agent forthwith on demand such corresponding amount together with interest thereon, for each day from the date such amount is made available to the Borrower until the date such amount is repaid to the Administrative
Agent, at (i) in the case of the Borrower, the interest rate applicable at the time to the Loans comprising such Borrowing and (ii) in the case of such Bank, the Federal Funds Effective Rate. If such Bank shall repay to the Administrative
Agent such corresponding amount, such amount shall constitute such Bank’s Loan as part of such Borrowing for purposes of this Agreement. 
 (d) Notwithstanding any other provision of this Agreement, the Borrower shall not be entitled to request any Borrowing if the Interest Period requested with respect thereto would end after the Expiration Date.

 (e) The Borrower may refinance all or any part of any Borrowing with a new Borrowing of the same or a different Type,
subject to the conditions and limitations set forth in this Agreement. Any Borrowing or part thereof so refinanced shall be deemed to be repaid or prepaid in accordance with Section 2.04 or 2.10, as applicable, with the proceeds of the new
Borrowing, and the proceeds of the new Borrowing, to the extent they do not exceed the principal amount of the Borrowing being refinanced, shall not be paid by the Banks to the Administrative Agent or by the Administrative Agent to the Borrower
pursuant to paragraph (c) above. 
 Section 2.03 Notice of Borrowings. 
 (a) To request a Borrowing, the Borrower shall give the Administrative Agent notice thereof (a) in the case of a Eurodollar
Borrowing, not later than 9:00 a.m., Pacific time, three Business Days before a proposed borrowing and (b) in the case of an ABR Borrowing, not later than 9:00 a.m., Pacific time, the day of a proposed borrowing. Such notice shall be
irrevocable and shall in each case refer to this Agreement and specify (i) whether the Borrowing then being requested is to be a Eurodollar Borrowing or an ABR Borrowing; (ii) the date of such Borrowing (which shall be a Business Day) and
the amount thereof; and (iii) if such Borrowing is to be a Eurodollar Borrowing, the Interest Period with respect thereto. If no election as to the Type of Borrowing is specified in any such notice, then the requested Borrowing shall be an ABR
Borrowing. If no Interest Period with respect to any Eurodollar Borrowing is specified in any such notice, then the Borrower shall be deemed to have selected an Interest Period of one month’s duration. If the Borrower shall not have given
notice in accordance with this Section 2.03 of its election to refinance a Borrowing or given notice to the Administrative Agent not later than 9:00 a.m., Pacific time, on the last day of the Interest Period applicable to such Borrowing that it
will not refinance such Borrowing, then the Borrower shall be deemed to have given notice of an election to refinance such Borrowing with an ABR Borrowing. The Administrative Agent shall promptly advise the Banks of any notice given pursuant to this
Section 2.03 and of each Bank’s portion of the requested Borrowing. 
  

 18 








 Section 2.04 Repayment of Loans; Evidence of Debt. 
 (a) The Borrower hereby unconditionally promises to pay each Bank the then unpaid principal amount of each Loan of such Bank on the last
day of the Interest Period applicable to such Loan and on the Expiration Date. Each Loan shall bear interest on the outstanding principal balance thereof as set forth in Section 2.06. 
 (b) Each Bank shall maintain in accordance with its usual practice an account or accounts evidencing the indebtedness of the Borrower to
such Bank resulting from each Loan made by such Bank, including the amounts of principal and interest payable and paid to such Bank from time to time hereunder. 
 (c) The Administrative Agent shall maintain accounts in which it shall record (i) the amount and date of each Loan made hereunder,
the Type thereof and the Interest Period applicable thereto, (ii) the amount of any principal, interest or fees due and payable or to become due and payable from the Borrower to each Bank hereunder and (iii) the amount of any principal,
interest or fees received by the Administrative Agent hereunder for the account of the Banks and each Bank’s share thereof. 
 (d) The entries made in the accounts maintained pursuant to paragraph (b) or (c) of this Section shall be prima facie evidence of the existence and amounts of the obligations recorded therein; provided that the failure
of any Bank or the Administrative Agent to maintain such accounts or any error therein shall not in any manner affect the obligation of the Borrower to repay the Loans in accordance with the terms of this Agreement. 
 (e) Any Bank may request that Loans made by it be evidenced by a Note. In such event, the Borrower shall prepare, execute and deliver to
such Bank a Note payable to the order of such Bank (or, if requested by such Bank, to such Bank and its registered assigns). Thereafter, the Loans evidenced by such Note and interest thereon shall at all times (including after assignment pursuant to
Section 10.04) be represented by one or more Notes in such form payable to the order of the payee named therein (or, if such Note is a registered Note, to such payee and its registered assigns). 
 Section 2.05 Fees. 
 (a) The Borrower agrees to pay to each Bank, through the Administrative Agent, on the first Business Day of January, April, July and October of each year and on the date on which the Commitment of such Bank shall be reduced or terminated as
provided herein, a facility fee at the Applicable Rate (a “Facility Fee”) on the daily amount of the Commitment of such Bank during the preceding quarter (or shorter period commencing with the date hereof or ending with the
Expiration Date or the date on which the Commitment of such Bank shall be reduced or terminated). The Facility Fees shall accrue on each day at a rate per annum equal to the Applicable Rate in effect on such day. All Facility Fees shall be computed
on the basis of a 

  

 19 








 
year of 365 or 366 days, as the case may be, and shall be payable for the actual number of days elapsed (including the first day but excluding the last day).
The Facility Fee due to each Bank shall commence to accrue on the date of this Agreement and shall cease to accrue on the date on which the Commitment of such Bank shall be terminated as provided herein. 
 (b) The Borrower agrees to pay to the Administrative Agent, for its own account, the fees separately agreed between the Administrative
Agent and the Borrower. 
 (c) Once paid, none of the Fees shall be refundable under any circumstances. 
 Section 2.06 Interest on Loans. 
 (a) Subject to the provisions of Section 2.07, the Loans comprising each ABR Borrowing shall bear interest at a rate per annum equal to the Alternate Base Rate plus the Applicable Rate. 
 (b) Subject to the provisions of Section 2.07, the Loans comprising each Eurodollar Borrowing shall bear interest at a rate per annum
equal to the Eurodollar Rate for the Interest Period in effect for such Borrowing plus the Applicable Rate. 
 (c) Interest on
each Loan shall be payable on the Interest Payment Dates applicable to such Loan except as otherwise provided in this Agreement. 
 (d) Interest computed on the basis of the Alternative Base Rate (including interest payable on overdue amounts under Section 2.07) shall be computed on the basis of a year of 365 or 366 days, as the case may be, for the actual number
of days elapsed so long as the Reference Rate is the applicable rate for calculation of the Alternate Base Rate, and on the basis of a year of 360 days for the actual number of days elapsed so long as the Federal Funds Effective Rate is the
applicable rate for calculation of the Alternate Base Rate. Interest computed on the basis of the Eurodollar Rate (including interest payable on overdue amounts under Section 2.07) shall be computed on the basis of a year of 360 days for the
actual number of days elapsed. 
 (e) The applicable Alternate Base Rate or Eurodollar Rate for each Interest Period or day
within an Interest Period, as the case may be, shall be determined by the Administrative Agent, and such determination shall be conclusive absent manifest error. 
 Section 2.07 Default Interest. If the Borrower shall default in the payment of the principal of or interest on any Loan or any other amount becoming due under the Loan Documents, by acceleration or otherwise,
the Borrower shall on demand from time to time pay interest, to the extent permitted by law, on such defaulted amount up to (but not including) the date of actual payment (after as well as before judgment) at a rate per annum equal to the Alternate
Base Rate plus the Applicable Rate plus 2% (except that the interest rate applicable to an overdue amount of principal of a Eurodollar Borrowing that became due on a day other than on the last day of the Interest Period applicable thereto shall, for
the period until the last day of such Interest Period, be equal to 2% above the rate that would otherwise be applicable thereto during such Interest Period). 
  

 20 








 Section 2.08 Alternate Rate of Interest. In the event, and on each occasion, that on the day two
Business Days prior to the commencement of any Interest Period for a Eurodollar Borrowing the Administrative Agent shall have in good faith determined that dollar deposits in the principal amounts of the Loans comprising such Borrowing are not
generally available in the London interbank market, or that the rates at which such dollar deposits are being offered will not adequately and fairly reflect the cost to the majority in interest of the Banks of making or maintaining their Eurodollar
Loans during such Interest Period, or that reasonable means do not exist for ascertaining the Eurodollar Rate, the Administrative Agent shall, as soon as practicable thereafter, give notice of such determination to the Borrower and the Banks. In the
event of any such determination, any request by the Borrower for a Eurodollar Borrowing pursuant to Section 2.03 shall, until the Administrative Agent shall have advised the Borrower and the Banks that the circumstances giving rise to such
notice no longer exist, be deemed to be a request for an ABR Borrowing. Each determination by the Administrative Agent hereunder shall be conclusive absent manifest error. 
 Section 2.09 Termination, Reduction and Increase in Commitments. 
 (a) The Commitments shall be automatically terminated on the Expiration Date. 
 (b) Upon at least three Business Days’ prior irrevocable notice to the Administrative Agent, the Borrower may at any time in whole
permanently terminate, or from time to time in part permanently reduce, the unused portion of the Commitments; provided, however, that (i) each partial reduction of the Commitments shall be in the aggregate amount of $5,000,000 or
a higher whole-integer multiple thereof, and (ii) the Borrower shall not terminate or reduce the Commitments if, after giving effect to any concurrent prepayment of the Loans in accordance with Section 2.10, the sum of the Revolving Credit
Exposures would exceed the total Commitments. 
 (c) At any time following the date of this Agreement and prior to the
Expiration Date, the aggregate amount of the Commitments may, at the option of the Borrower, be increased by an amount not in excess of $50,000,000, either by new Banks establishing Commitments or by one or more then-existing Banks increasing their
Commitments (each such new Bank or Bank increasing its Commitment, an “Additional Commitment Bank”); provided that (i) each Additional Commitment Bank shall be selected or approved by the Borrower and shall be
reasonably acceptable to the Administrative Agent, (ii) no Bank shall have an obligation to become an Additional Commitment Bank, (iii) no Default or Event of Default shall exist immediately prior to or after the effective date of the
increase in the Commitments, (iv) the representations and warranties set forth in Article III shall be true and correct in all material respects on and as of the effective date of the increase in the Commitments with the same effect as if
made on and as of such date, except to the extent that such representations and warranties expressly relate to an earlier date, (v) each increase in the Commitments shall be in an aggregate amount not less than $10,000,000 and multiples of
$5,000,000 in excess thereof, (vi) the 

  

 21 








 
aggregate amount of the increase in the Commitments after the date of this Agreement shall not exceed $50,000,000, and (vii) no increase in the
Commitments shall become effective unless and until (A) the Borrower, the Administrative Agent and each Additional Commitment Bank shall have executed and delivered an agreement substantially in the form of Exhibit D (a “Commitment
Increase Supplement”) and (B) the Administrative Agent shall have received a substitute First Mortgage Bond in an amount equal to the total Commitments after giving effect to the increase in the Commitments, together with a
supplemental indenture, a bond delivery agreement, mortgage title insurance, legal opinions and other certificates and documents with respect thereto comparable to those delivered pursuant to Section 4.02(a) with respect to the First Mortgage
Bond issued under the First Mortgage and delivered to the Administrative Agent on the Closing Date, in each case in form and substance satisfactory to the Administrative Agent. On the effective date of an increase in the Commitments, each Additional
Commitment Bank shall purchase, as an assignment from each other existing Bank, the portion of such other Bank’s Loans outstanding at such time such that, after giving effect to such assignments, the respective aggregate amount of Loans of each
Bank shall be equal to such Bank’s Pro Rata Share of the aggregate Loans outstanding. The purchase price for the Loans so assigned shall be the sum of the principal amount of the Loans so assigned plus the amount of accrued and unpaid interest
thereon as of the date of assignment. Each Additional Commitment Bank shall pay the aggregate purchase price payable by it to the Administrative Agent on the effective date of an increase in the Commitments, and the Administrative Agent shall
promptly forward to each other Bank the portion thereof payable to it. Upon payment of such purchase price, each other Bank shall be automatically deemed to have sold and made such an assignment to such Additional Commitment Bank and shall, to the
extent of the interest assigned, be released from its obligations under the Loan Documents, and such Additional Commitment Bank shall be automatically deemed to have purchased and assumed such an assignment from each other Bank and, if not already a
Bank hereunder, shall be a party hereto and, to the extent of the interest assigned, have the rights and obligations of a Bank under the Loan Documents. 
 Section 2.10 Prepayment. The Borrower shall have the right at any time and from time to time to prepay any Borrowing, in whole or in part, upon at least three Business Days’ prior notice to the
Administrative Agent, in the case of a prepayment of a Eurodollar Borrowing, and upon at least one Business Day’s prior notice, in the case of a prepayment of an ABR Borrowing; provided, however, that each partial prepayment shall
be in the amount of $1,000,000 or a higher whole-integer multiple thereof. Each notice of prepayment shall specify the prepayment date and the principal amount of each Borrowing (or portion thereof) to be prepaid, shall be irrevocable and shall
commit the Borrower to prepay such Borrowing by the amount stated therein on the date stated therein. All prepayments under this Section 2.10 shall be subject to Section 2.13 but otherwise without premium or penalty. All prepayments under
this Section 2.10 shall be accompanied by accrued interest on the principal amount being prepaid to (but excluding) the date of payment. 
 Section 2.11 Reserve Requirements; Change in Circumstances. 
 (a) Notwithstanding any other provision herein,
if after the date of this Agreement there is adopted any new law, rule or regulation or any change in applicable law or regulation or in the interpretation or administration thereof by any Governmental Authority 

  

 22 








 
charged with the interpretation or administration thereof (whether or not having the force of law) which shall impose, modify or deem applicable any reserve,
special-deposit or similar requirement against assets of, deposits with or for the account of or credit extended by any Bank (except any such reserve requirement which is reflected in the Eurodollar Rate) or shall impose on such Bank or the London
interbank market any other condition affecting this Agreement or Eurodollar Loans made by such Bank, and the result of any of the foregoing shall be to increase the cost to such Bank of making or maintaining any Eurodollar Loan or to reduce the
amount of any sum received or receivable by such Bank hereunder or under any Notes (whether of principal, interest or otherwise) by an amount deemed by such Bank to be material, then the Borrower will pay to such Bank upon demand such additional
amount or amounts as will compensate such Bank for such additional costs incurred or reduction suffered. 
 (b) If any Bank
shall have determined that the applicability of any law, rule, regulation, agreement or guideline adopted after the date hereof regarding capital adequacy, or any change in any of the foregoing or the adoption after the date hereof of any change in
any law, rule, regulation, agreement or guideline existing on the date hereof or in the interpretation or administration of any of the foregoing by any Governmental Authority charged with the interpretation or administration thereof, or compliance
by any Bank (or any lending office thereof) or any Bank’s holding company with any request or directive regarding capital adequacy (whether or not having the force of law) of any such authority, central bank or comparable agency, has or would
have the effect of reducing the rate of return on such Bank’s capital or on the capital of such Bank’s holding company, if any, with respect to this Agreement or Loans made by such Bank to a level below that which such Bank or such
Bank’s holding company could have achieved but for such applicability, adoption, change or compliance (taking into consideration such Bank’s policies and the policies of such Bank’s holding company with respect to capital adequacy) by
an amount deemed by such Bank to be material, then from time to time the Borrower shall pay to such Bank such additional amount or amounts as will compensate such Bank or such Bank’s holding company for any such reduction suffered. It is
acknowledged that this Agreement is being entered into by the Banks on the understanding that the Banks will not be required to maintain capital against their obligations to make Loans under currently applicable laws, regulations and regulatory
guidelines. In the event that the Banks shall be advised by any Governmental Authority or shall otherwise determine on the basis of pronouncements of any Governmental Authority that such understanding is incorrect, it is agreed that the Banks will
be entitled to make claims under this paragraph based upon market requirements prevailing on the date hereof for commitments under comparable credit facilities against which capital is required to be maintained. 
 (c) A certificate of a Bank setting forth in reasonable detail such amount or amounts as shall be necessary to compensate such Bank or
such Bank’s holding company as specified in paragraph (a) or (b) above, as the case may be, and the manner in which such Bank has determined the same, shall be delivered to the Borrower and shall be conclusive absent manifest error.
The Borrower shall pay the Bank the amount shown as due on any such certificate delivered by it within 10 days after its receipt of the same. 
  

 23 








 (d) Failure on the part of any Bank to demand compensation for any increased costs or
reduction in amounts received or receivable or reduction in return on capital with respect to any period shall not constitute a waiver of such Bank’s right to demand compensation with respect to such period or any other period. The protection
of this Section shall be available to each Bank regardless of any possible contention of the invalidity or inapplicability of the law, rule, regulation, guideline or other change or condition which shall have occurred or been imposed.

 Section 2.12 Change in Legality. 
 (a) Notwithstanding any other provision herein, if any change in, or adoption of, any law or regulation or in the interpretation thereof by any Governmental Authority charged with the administration or interpretation
thereof shall make it unlawful for any Bank to make or maintain any Eurodollar Loan or to give effect to its obligations as contemplated hereby with respect to any Eurodollar Loan, then, by notice to the Borrower and to the Administrative Agent,
such Bank may: 
 (i) declare that Eurodollar Loans will not thereafter be made by such Bank hereunder, whereupon any request
by the Borrower for a Eurodollar Borrowing shall, as to such Bank only, be deemed a request for an ABR Loan unless such declaration shall be subsequently withdrawn; and 
 (ii) require that all outstanding Eurodollar Loans made by it be converted to ABR Loans, in which event all such Eurodollar Loans shall be
automatically converted to ABR Loans as of the effective date of such notice as provided in paragraph (b) below. 
 In the event any Bank shall exercise
its rights under (i) or (ii) above, all payments and prepayments of principal which would otherwise have been applied to repay the Eurodollar Loans that would have been made by such Bank or the converted Eurodollar Loans of such Bank shall
instead be applied to repay the ABR Loans made by such Bank in lieu of, or resulting from the conversion of, such Eurodollar Loans. 
 (b) For purposes of this Section 2.12, a notice to the Borrower by any Bank shall be effective as to each Eurodollar Loan, if lawful, on the last day of the Interest Period currently applicable to such Eurodollar Loan. 
 Section 2.13 Indemnity. The Borrower shall indemnify each Bank against any loss or expense which such Bank may sustain or incur as a consequence
of (a) any failure by the Borrower to fulfill on the date of any Eurodollar Borrowing hereunder the applicable conditions set forth in Article IV, (b) any failure by the Borrower to borrow any Eurodollar Loan hereunder after
irrevocable notice of such borrowing has been given or deemed given pursuant to Section 2.03, (c) any payment or prepayment of a Eurodollar Loan required by any provision of this Agreement or otherwise made or deemed made on a date other
than the last day of the Interest Period applicable thereto, (d) any assignment of a Eurodollar Loan pursuant to Section 2.18(b) made or deemed made on a date other than the last day of the Interest Period applicable thereto, or
(e) any default in payment or prepayment of the principal amount of any Eurodollar Loan or any part thereof or interest accrued thereon, as and when due and payable (at 

  

 24 








 
the due date thereof, whether by scheduled maturity, acceleration, irrevocable notice of prepayment or otherwise) including, in each such case, any loss or
reasonable expense sustained or incurred or to be sustained or incurred in liquidating or employing deposits from third parties acquired to effect or maintain such Loan or any part thereof as a Eurodollar Loan. Such loss or reasonable expense shall
include an amount equal to the excess, if any, as reasonably determined by such Bank, of (i) its cost of obtaining the funds for the Eurodollar Loan being paid, prepaid, assigned or not borrowed (assumed to be the Eurodollar Rate applicable
thereto) for the period from the date of such payment, prepayment, assignment or failure to borrow to the last day of the Interest Period for such Loan (or, in the case of a failure to borrow, the Interest Period for such Eurodollar Loan which would
have commenced on the date of such failure) over (ii) the amount of interest (as reasonably determined by such Bank) that would be realized by such Bank in reemploying the funds so paid, prepaid, assigned or not borrowed for such period or
Interest Period, as the case may be. A certificate of any Bank setting forth any amount or amounts which such Bank is entitled to receive pursuant to this Section, and the manner in which such Bank has determined the same, shall be delivered to the
Borrower and shall be conclusive absent manifest error. 
 Section 2.14 Pro Rata Treatment. Except as required under
Section 2.12, each Borrowing, each payment or prepayment of principal of any Borrowing, each payment of interest on the Loans, each payment of the Fees, and each reduction of the Commitments shall be allocated among the Banks in accordance with
their respective Pro Rata Shares. Each Bank agrees that, in computing such Bank’s portion of any Borrowing to be made hereunder, the Administrative Agent may, in its discretion, round each Bank’s Pro Rata Share of such Borrowing to the
next higher or lower whole-dollar amount. 
 Section 2.15 Sharing of Setoffs. Each Bank agrees that if it shall, through the exercise
of a right of banker’s lien, setoff or counterclaim against the Borrower, or pursuant to a secured claim under Section 506 of Title 11 of the United States Code or other security or interest arising from, or in lieu of, such secured claim,
received by such Bank under any applicable bankruptcy, insolvency or other similar law or otherwise, or by any other means, obtain payment (voluntary or involuntary) in respect of its Loans as a result of which the unpaid principal portion of its
Loans shall be proportionately less than the unpaid principal portion of the Loans of any other Bank, it shall be deemed simultaneously to have purchased from such other Bank at face value, and shall promptly pay to such other Bank the purchase
price for, a participation in the Loans of such other Bank (“Sharing Participations”), so that (a) the aggregate unpaid principal amount of the Loans and Sharing Participations held by each Bank shall be in the same
proportion to the aggregate unpaid principal amount of all Loans then outstanding as (b) the principal amount of its Loans and Sharing Participations prior to such exercise of banker’s lien, setoff or counterclaim or other event was to the
principal amount of all Loans outstanding prior to such exercise of banker’s lien, setoff or counterclaim or other event; provided, however, that, if any such purchase or purchases or adjustments shall be made pursuant to this
Section and the payment giving rise thereto shall thereafter be recovered, such purchase or purchases or adjustments shall be rescinded to the extent of such recovery and the purchase price or prices or adjustment restored without interest. The
Borrower expressly consents to the foregoing arrangements and agrees that any Bank holding a participation in a Loan deemed to have been so purchased may exercise any and all rights of banker’s lien, setoff or counterclaim with respect to any
and all moneys owing by the Borrower to such Bank by reason thereof as fully as if such Bank had made a Loan directly to the Borrower in the amount of such participation. 
  


 25 








 Section 2.16 Payments. 
 (a) The Borrower shall make each payment (including principal of or interest on any Borrowing or any Fees or other amounts) hereunder and
under any other Loan Document not later than 9:00 a.m., Pacific time, on the date when due in dollars to the Administrative Agent at its offices at 445 South Figueroa Street, Los Angeles, California 90071, in immediately available funds. 

(b) Whenever any payment (including principal of or interest on any Borrowing or any Fees or other amounts) hereunder or under any
other Loan Document shall become due, or otherwise would occur, on a day that is not a Business Day, such payment may be made on the next succeeding Business Day, and such extension of time shall in such case be included in the computation of
interest or Fees, if applicable. 
 Section 2.17 Taxes. 
 (a) Any and all payments by the Borrower hereunder and under any other Loan Document shall be made, in accordance with Section 2.16,
free and clear of and without deduction for any and all present or future taxes, levies, imposts, deductions, charges or withholdings, and all liabilities with respect thereto, excluding taxes imposed on the net income of the Administrative Agent or
any Bank (or any transferee or assignee thereof, including a participation holder (any such entity being called a “Transferee”)) and franchise taxes imposed on the Administrative Agent or any Bank (or Transferee) by the
United States or any jurisdiction under the laws of which the Administrative Agent or any such Bank (or Transferee) or the applicable lending office, is organized or any political subdivision thereof (all such nonexcluded taxes, levies, imposts,
deductions, charges, withholdings and liabilities being hereinafter referred to as “Taxes”). If the Borrower shall be required by law to deduct any Taxes from or in respect of any sum payable under any Loan Document to the
Banks (or any Transferee) or the Administrative Agent, (i) the sum payable shall be increased by the amount necessary so that after making all required deductions of Taxes (including deductions applicable to additional sums payable under this
Section 2.17) such Bank (or Transferee) or the Administrative Agent (as the case may be) shall receive an amount equal to the sum it would have received had no such deductions of Taxes been made, (ii) the Borrower shall make such
deductions and (iii) the Borrower shall pay the full amount deducted to the relevant taxing authority or other Governmental Authority in accordance with applicable law; provided, however, that no Transferee of any Bank shall be
entitled to receive any greater payment under this paragraph (a) than such Bank would have been entitled to receive with respect to the rights assigned, participated or other wise transferred except to the extent that such greater payment
arises from circumstances not in existence at the time such assignment, participation or transfer shall have been made. 
  

 26 








 (b) In addition, the Borrower agrees to pay any present or future stamp or documentary
taxes or any other excise or property taxes, charges or similar levies which arise from any payment made under any Loan Document or from the execution, delivery or registration of, or otherwise with respect to, this Agreement or any other Loan
Document (hereinafter referred to as “Other Taxes”). 
 (c) The Borrower will indemnify each Bank (or
Transferee) and the Administrative Agent for the full amount of any Taxes and Other Taxes paid by such Bank (or Transferee) or the Administrative Agent, as the case may be, and any liability (including penalties, interest and reasonable expenses)
arising therefrom or with respect thereto, whether or not such Taxes or Other Taxes were correctly or legally asserted by the relevant taxing authority or other Governmental Authority. Such indemnification shall be made within 30 days after the date
any Bank (or Transferee) or the Administrative Agent, as the case may be, makes written demand therefor. If a Bank (or Transferee) or the Administrative Agent shall become aware that it is entitled to receive a refund in respect of Taxes or Other
Taxes as to which it has been indemnified by the Borrower pursuant to this Section 2.17, it shall promptly notify the Borrower of the availability of such refund and shall, within 30 days after receipt of a request by the Borrower, apply for
such refund at the Borrower’s expense. 
 (d) If any Bank (or Transferee) or the Administrative Agent receives a refund
in respect of any Taxes or Other Taxes as to which it has been indemnified by the Borrower pursuant to this Section 2.17, it shall promptly notify the Borrower of such refund and shall repay such refund to the Borrower (to the extent of amounts
that have been paid by the Borrower under this Section 2.17 with respect to such refund) within 30 days (or promptly upon receipt, if the Borrower has requested application for such refund pursuant hereto), net of all reasonable out-of-pocket
expenses of such Bank (or Transferee) and without interest (other than interest included in such refund); provided that the Borrower, upon the request of such Bank (or Transferee) or the Administrative Agent, agrees to return such refund
(plus penalties, interest or other charges) to such Bank (or Transferee) or the Administrative Agent in the event such Bank (or Transferee) or the Administrative Agent is required to repay such refund. Nothing contained in this paragraph
(d) shall require any Bank (or Transferee) or the Administrative Agent to make available any of its tax returns (or any other information relating to its taxes which it deems to be confidential); provided that Borrower, at its expense,
shall have the right to receive an opinion from a firm of independent public accountants of recognized national standing acceptable to the Borrower that the amount due hereunder is correctly calculated. 
 (e) Within 30 days after the date of any payment of Taxes or Other Taxes withheld by the Borrower in respect of any payment to any Bank
(or Transferee) or the Administrative Agent, the Borrower will furnish to the Administrative Agent, at its address referred to in Section 10.01, the original or a certified copy of a receipt received by the Borrower evidencing payment thereof.

 (f) Without prejudice to the survival of any other agreement contained herein, the agreements and obligations contained in
this Section 2.17 shall survive the payment in full of the principal of and interest on all Loans made hereunder. 
  

 27 








 (g) On or prior to the execution of this Agreement and on or before the transfer to a
Transferee, the Administrative Agent shall notify the Borrower of each Bank’s (or Transferee’s) address. On or prior to the Banks’ (or any Transferee’s) first Interest Payment Date, and from time to time as required by law, each
Bank (or Transferee) that is not a United States person within the meaning of Section 7701(a)(30) of the Code (a “Non-U.S. Person”) shall, if legally able to do so, deliver to the Borrower and the Administrative Agent
(i) one duly completed and executed copy of United States Internal Revenue Service Form W-8BEN or W-8ECI, (ii) if claiming exemption from United States Federal withholding tax pursuant to Section 871(h) or 881(c) of the Code, one duly
completed and executed copy of a United States Internal Revenue Service Form W-8BEN and a certificate representing that such Non-U.S. Person is not a bank for purposes of Section 881(c) of the Code, is not a 10 percent shareholder (within the
meaning of Section 871(h)(3)(b) of the Code) of the Borrower and is not a controlled foreign corporation related to the Borrower (within the meaning of Section 864(d)(4) of the Code) or (iii) any successor applicable form of any
thereof, establishing in each case that such Bank (or Transferee) is entitled to receive payments under the Loan Documents payable to it without deduction or withholding of any United States Federal income taxes, or is subject to a reduced rate
thereof. Unless the Borrower and the Administrative Agent have received forms or other documents satisfactory to them indicating that such payments under the Loan Documents are not subject to United States Federal withholding tax or are subject to
such tax at a rate reduced by an applicable tax treaty, the Borrower shall withhold taxes from such payments at the applicable statutory rate. 
 (h) The Borrower shall not be required to pay any additional amounts to any Bank (or Transferee) in respect of United States Federal withholding tax pursuant to paragraph (a) above if the obligation to pay such
additional amounts would not have arisen but for a failure by such Bank (or Transferee) to comply with the provisions of paragraph (g) above; provided, however, that the Borrower shall be required to pay those amounts to any Bank
(or Transferee) that it was required to pay hereunder prior to the failure of such Bank (or Transferee) to comply with the provisions of such paragraph (g). 
 Section 2.18 Termination or Assignment of Commitments under Certain Circumstances. 
 (a) Any Bank (or Transferee) claiming any additional amounts payable pursuant to Section 2.11 or Section 2.17 or exercising its rights under Section 2.12 shall use reasonable efforts (consistent with legal and regulatory
restrictions) to file any certificate or document requested by the Borrower or to change the jurisdiction of its applicable lending office if the making of such a filing or change would avoid the need for or reduce the amount of any such additional
amounts which may thereafter accrue or avoid the circumstances giving rise to such exercise and would not, in the sole determination of such Bank, be otherwise disadvantageous to such Bank (or Transferee). 
 (b) In the event that any Bank shall have delivered a notice or certificate pursuant to Section 2.12, or the Borrower shall be
required to make additional payments under Section 2.11 or 2.17 to any Bank (or Transferee) or to the Administrative Agent with respect to any Bank (or Transferee), the Borrower shall have the right, at its own expense, upon notice to such Bank
(or Transferee) and the Administrative Agent, (i) to terminate the Commitment of such Bank (or Transferee) or (ii) to require such Bank (or Transferee) to transfer and assign 

  

 28 








 
without recourse (in accordance with and subject to the restrictions contained in Section 10.04) all its interests, rights and obligations under the
Loan Documents to another financial institution which shall assume such obligations; provided that (A) no such termination or assignment shall conflict with any law, rule or regulation or order of any Governmental Authority and
(B) the Borrower or the assignee, as the case may be, shall pay to the affected Bank (or Transferee) in immediately available funds on the date of such termination or assignment the principal of and interest accrued to the date of payment on
the Loans made by it hereunder and all other amounts accrued for its account or owed to it under the Loan Documents. 
 Section 2.19
Extension of Expiration Date. 
 (a) If no Event of Default has occurred and is continuing, the Borrower may request,
by notice to the Administrative Agent and each Bank given no earlier than 45 days before, and no later than 30 days before, the Expiration Date applicable on the date of such notice (the “Current Expiration Date”), that the
Banks renew their respective Commitments for an additional 364 days. If a Bank agrees, in its sole and absolute discretion, to so renew its Commitment, it will give notice to the Administrative Agent of its decision to do so no earlier than 30 days
before, and no later than 20 days before, the Current Expiration Date. No later than 19 days before the Current Expiration Date (or the next Business Day, if the day 19 days before the Current Expiration Date is not a Business Day), the
Administrative Agent will notify the Borrower and each Bank as to the Banks (each a “Renewing Bank”) from which it has received such a notice agreeing to so renew. Any failure by a Bank to so notify the Administrative Agent
shall be deemed to be a decision by such Bank not to so renew its Commitment. 
 (b) If all Banks elect to so renew their
respective Commitments, and provided that the additional conditions specified in Section 4.03 shall have been satisfied, then on the Current Expiration Date the Expiration Date shall automatically become the date that is 364 days following the
Current Expiration Date. 
 (c) If, at the time the Administrative Agent gives the notice contemplated by Section 2.19(a)
to the Borrower and the Banks, the Commitments of the Renewing Banks aggregate at least 66-2/3% , but less than 100%, of the Commitments of all of the Banks at such time (the “Existing Commitments”), then (i) as to each
Renewing Bank, on the Current Expiration Date the Expiration Date shall automatically become the date that is 364 days following the Current Expiration Date, provided that the additional conditions specified in Section 4.03 shall have been
satisfied, (ii) the Expiration Date shall remain unchanged as to each Bank that is not a Renewing Bank (each a “Terminating Bank”), (iii) each Terminating Bank’s Commitment shall terminate on the Current
Expiration Date, and (iv) on the Current Expiration Date the Borrower shall pay the outstanding Loans owed to each Terminating Bank and all other amounts owed to each Terminating Bank. If, at the time the Administrative Agent gives the notice
contemplated by Section 2.19(a) to the Borrower and the Banks, the Commitments of the Renewing Banks aggregate less than 66-2/3% of the Existing Commitments, none of the Commitments (including the Commitment of any Renewing Bank) shall be
extended, and the Expiration Date shall remain unchanged. 
  

 29 








 (d) The Borrower may undertake the process contemplated by this Section 2.19 once
each year (commencing in 2009), but the election by any Bank to become a Renewing Bank at any time shall not obligate such Bank to become a Renewing Bank at any other time, it being agreed that each election by any Bank to renew or not renew shall
be made by such Bank in its sole and absolute discretion and that such discretion shall not be limited by any prior election to become a Renewing Bank. 
 (e) If, at any time that the Administrative Agent gives a notice contemplated by Section 2.19(a) to the Borrower and the Banks, the Commitments of the then Renewing Banks aggregate at least 66-2/3% but less than
100% of the then Existing Commitments, the Borrower shall have the right, without the consent of the Banks but subject to the consent of the Administrative Agent (which consent shall not be unreasonably withheld), to replace the Commitments of the
then Terminating Banks by adding to this Agreement one or more commercial banks or other financial institutions (which shall, upon completion of the requirements stated in this Section 2.19, constitute Banks hereunder) or by allowing one or
more Renewing Banks to increase their Commitments hereunder, provided that (i) such added and increased Commitments shall not be greater than the Commitments of such Terminating Banks, so that in no event will the aggregate amount of the
Existing Commitments be increased (after giving effect to the contemporaneous termination of the Commitments of such Terminating Banks), (ii) no Renewing Bank’s Commitment shall be increased without the consent of such Renewing Bank, and
(iii) the additional conditions specified in Section 4.03 shall have been satisfied. The Borrower shall give the Administrative Agent three Business Days’ notice of the Borrower’s intention to increase any Commitment or add a new
commercial bank or other financial institution pursuant to this Section 2.19. Such notice shall specify each new commercial bank or other financial institution, if any, the changes in amounts of Commitments that will result and such other
information as is reasonably requested by the Administrative Agent. Each new commercial bank or other financial institution agreeing to be added to this Agreement, and each Renewing Bank agreeing to increase its Commitment, shall execute and deliver
to the Administrative Agent an agreement substantially in the form of Exhibit E (a “Commitment Extension Supplement”), pursuant to which it shall become a party hereto or increase its Commitment, as the case may be. In
addition, the Borrower shall execute and deliver a Note in the principal amount of the Commitment of each new Bank, or a replacement Note in the principal amount of the increased Commitment of each Renewing Bank agreeing to increase its Commitment,
if and to the extent requested pursuant to Section 2.04(e). Upon execution by the Administrative Agent of the relevant Commitment Extension Supplement, each such new commercial bank or financial institution shall constitute a “Bank”
hereunder with a Commitment as specified therein, or such Renewing Bank’s Commitment shall increase as specified therein, as the case may be. 
  

 30

instrument evidencing or relating to borrowed money to which the Borrower or any Significant Subsidiary is a party or by which any of them or any of their property is or may be bound in a manner which could reasonably be expected to impair the
validity and enforceability of this Agreement or any other Loan Document or materially impair the rights of or benefits available to the Banks under the Loan Documents, (ii) be in conflict with, result in a breach of or constitute (alone or
with notice or lapse of time or both) a default under any such indenture, agreement or other instrument in a manner which could reasonably be expected to impair the validity and enforceability of this Agreement or any other Loan Document or

with the Borrower’s Annual Report on Form 10-K for the fiscal year ended December 31, 2007, reflect all liabilities, direct or contingent, of the Borrower and its consolidated Subsidiaries as of the dates thereof which are material on a
consolidated basis. Such financial statements were prepared in accordance with GAAP applied (except as noted therein) on a consistent basis.

since December 31, 2007, which could reasonably be expected to have a Material Adverse Effect. For the avoidance of doubt, the representation set forth in this Section 3.06 is and will be made solely at and as of the Closing Date and at
and as of the effective date of any increase in the Commitments pursuant to Section 2.09(c). 
 Section 3.07 Litigation; Compliance

 (b) Neither the Borrower nor any of the Subsidiaries is in violation of any law, rule or regulation, or in default with respect to any
judgment, writ, injunction or decree of any Governmental Authority, where such violation or default would be reasonably likely to result in a Material Adverse Effect.

Subsidiaries is engaged principally, or as one of its important activities, in the business of extending credit for the purpose of purchasing or carrying Margin Stock.

(i) to purchase or carry Margin Stock or to extend credit to others for the purpose of purchasing or carrying Margin Stock or to refund indebtedness originally incurred for such purpose, or (ii) for any purpose which entails a violation
of, or which is inconsistent with, the provisions of the Regulations of the Board, including Regulation U or X. 
  

 32 








 Section 3.09 Investment Company Act. The Borrower is not an “investment company” as
defined in, or subject to regulation under, the Investment Company Act of 1940. 
 Section 3.10 No Material Misstatements. No
information, report, financial statement, exhibit or schedule furnished by or on behalf of the Borrower to the Administrative Agent or any Bank in connection with the negotiation of any Loan Document or included therein or delivered pursuant thereto
contained, contains or will contain any material misstatement of fact or, when considered together with all reports theretofore filed with the Securities and Exchange Commission, omitted, omits or will omit to state any material fact necessary to
make the statements therein, in the light of the circumstances under which they were, are or will be made, not misleading. 
 Section 3.11
Employee Benefit Plans. Each of the Borrower and its ERISA Affiliates is in compliance in all material respects with the applicable provisions of ERISA and the regulations and published interpretations thereunder. No Reportable Event has
occurred as to which the Borrower or any ERISA Affiliate was required to file a report with the PBGC. The value of the assets of each Plan is at least 80% of the “funding target” (as defined in Code Section 430(d)(1)) of such Plan as

Subsidiaries has complied with all Federal, state, local and other statutes, ordinances, orders, judgments, rulings and regulations relating to environmental pollution or to environmental or nuclear regulation or control or to employee health or
safety, except where noncompliance would not be reasonably likely to result in a Material Adverse Effect. Neither the Borrower nor any Subsidiary has received notice of any failure so to comply, except where noncompliance would not be reasonably
likely to result in a Material Adverse Effect. The Borrower’s and the Subsidiaries’ plants do not manage any hazardous wastes, hazardous substances, hazardous materials, toxic substances, toxic pollutants or substances similarly

Act, the Clean Air Act, the Clean Water Act or any other applicable law relating to environmental pollution or employee health and safety, or any nuclear fuel or other radioactive materials, in all cases in violation of any law or any regulations
promulgated pursuant thereto, where such violation would be reasonably likely to result in a Material Adverse Effect. The Borrower is aware of no events, conditions or circumstances involving environmental pollution or contamination or employee
health or safety that could reasonably be expected to result in a Material Adverse Effect. The representations and warranties set forth in this Section 3.12 are, however, subject to any matters, circumstances or events set forth in the
Borrower’s Annual Report on Form 10-K for the fiscal year ended December 31, 2007 and in any document filed after December 31, 2007, but prior to the date of this Agreement pursuant to Section 13(a), 14 or 15(d) of the Securities
Exchange Act of 1934; provided, however, that the inclusion of such matters, circumstances or events as exceptions (or any other exceptions contained in the representations and warranties which refer to the

to the date of this Agreement pursuant to Section 13(a), 14 or 15(d) of the Securities Exchange Act of 1934) shall not be construed to mean that the Borrower has concluded that any such matter, circumstance or effect is likely to result in a
Material Adverse Effect.

 (a) any representation or warranty made or deemed made in or in connection with any Loan Document or the Borrowings, or any representation

first-priority Lien (subject to Liens permitted to exist by the terms of the First Mortgage) securing the obligations of the Borrower under the First Mortgage (including the obligations of the First Mortgage Bond), and such failure shall constitute
or have resulted in a “Completed Default” under the First Mortgage; or

 THE ADMINISTRATIVE AGENT 
 Section 9.01 Appointment and Powers. In order
to expedite the various transactions contemplated by the Loan Documents, UBOC is hereby appointed to act as Administrative Agent on behalf of the Banks. Each of the Banks hereby irrevocably authorizes and directs the Administrative Agent to take
such action on behalf of such Bank under the terms and provisions of the Loan Documents, and to exercise such powers thereunder as are specifically delegated to or required of the Administrative Agent by the terms and provisions thereof, together
with such powers as are reasonably incidental thereto. The Administrative Agent is hereby expressly authorized on behalf of the Banks, without hereby limiting any implied authority, (a) to receive on behalf of each of the Banks any payment of
principal of or interest on the Loans outstanding hereunder and all other amounts accrued under the Loan Documents paid to the Administrative Agent, and to distribute to each Bank its proper share of all payments so received as soon as practicable;
(b) to give notice promptly on behalf of each of the Banks to the Borrower of any Event of Default of which the Administrative Agent has actual knowledge acquired in connection with its agency hereunder; and (c) to distribute promptly to
each Bank copies of all notices, agreements and other material as provided for in the Loan Documents as received by such Administrative Agent. 
  

 49 








 Section 9.02 Limitation on Liability. Neither the Administrative Agent nor any of its directors,
officers, employees or agents shall be liable to any Bank as such for any action taken or omitted by any of them under the Loan Documents except for its, his or her own gross negligence or willful misconduct, or be responsible for any statement,
warranty or representation therein or the contents of any document delivered in connection therewith or be required to ascertain or to make any inquiry concerning the performance or observance by the Borrower of any of the terms, conditions,
covenants or agreements of the Loan Documents. The Administrative Agent shall not be responsible to the Banks for the due execution, genuineness, validity, enforceability or effectiveness of the Loan Documents or any other instrument to which
reference is made therein. The Administrative Agent shall in all cases be fully protected in acting, or refraining from acting, in accordance with written instructions signed by the Required Banks, and, except as otherwise specifically provided
herein, such instructions and any action taken or failure to act pursuant thereto shall be binding on all the Banks. The Administrative Agent shall, in the absence of knowledge to the contrary, be entitled to rely on any paper or document believed
by it in good faith to be genuine and correct and to have been signed or sent by the proper person or persons. Neither the Administrative Agent nor any of its directors, officers, employees or agents shall have any responsibility to the Borrower on
account of the failure or delay in performance or breach by any Bank of any of its obligations under the Loan Documents or to any Bank on account of the failure of or delay in performance or breach by any other Bank or the Borrower of any of their
respective obligations thereunder or in connection therewith. The Administrative Agent may execute any of its duties under the Loan Documents by or through agents or attorneys selected by it using reasonable care and shall be entitled to advice of
counsel concerning all matters pertaining to such duties. The Administrative Agent shall not be responsible for the negligence or misconduct of any agents or attorneys selected and authorized to act by it with reasonable care unless the damage
complained of directly results from an act or failure to act on the part of the Administrative Agent which constitutes gross negligence or willful misconduct. Delegation to an attorney for the Administrative Agent shall not release the
Administrative Agent from its obligation to perform or cause to be performed the delegated duty. The Administrative Agent shall be entitled to advice of legal counsel selected by it with respect to all matters arising under the Loan Documents and
shall not be liable for any action taken or suffered in good faith by it in accordance with the advice of such counsel. 
 Section 9.03
Other Transactions with Borrower. The Administrative Agent and its Affiliates may accept deposits from, lend money to and generally engage in any kind of business with the Borrower or any Affiliate thereof as if it were not the Administrative
Agent. 
 Section 9.04 Reimbursement; Indemnification. Each Bank agrees (a) to reimburse the Administrative Agent in the amount
of such Bank’s Pro Rata Share of any expenses incurred for the benefit of the Banks by the Administrative Agent, including reasonable counsel fees and compensation of agents and employees paid for services rendered on behalf of the Banks, to
the extent not reimbursed by the Borrower and (b) to indemnify and hold harmless the Administrative Agent and any of its directors, officers, employees or agents, on demand, in the amount of its Pro Rata Share, from and against any and all
liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever which may be imposed on, incurred by or asserted against it in its capacity as the Administrative
Agent or any of them in any way relating to or arising out of the Loan 

  

 50 








 
Documents or any action taken or omitted by it or any of them under the Loan Documents, to the extent not reimbursed by the Borrower; provided,
however, that no Bank shall be liable to the Administrative Agent for any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements resulting from the gross negligence or
willful misconduct of the Administrative Agent or any of its directors, officers, employees or agents. 
 Section 9.05 Absence of
Reliance. Each of the Banks acknowledges that it has, independently and without reliance upon the Administrative Agent or any other Bank and based on such documents and information as it has deemed appropriate, made its own credit analysis and
decision to enter into this Agreement. Each of the Banks also acknowledges that it will, independently and without reliance upon the Administrative Agent or any Bank and based on such documents and information as it shall deem appropriate at the
time, continue to make its own decisions in taking or not taking action under or based upon the Loan Documents, any related agreement or any document furnished thereunder. 
 Section 9.06 Resignation of Administrative Agent. The Administrative Agent may at any time give notice of its resignation to the Banks and the
Borrower. Upon receipt of any such notice of resignation, the Required Banks may, with the consent of the Borrower (which consent shall not be unreasonably withheld and shall not be required during an Event of Default), appoint a successor
Administrative Agent. If no successor Administrative Agent shall have been so appointed by the Required Banks and shall have accepted such appointment within 30 days after the retiring Administrative Agent’s giving of notice of resignation,
then the retiring Administrative Agent may, on behalf of the Banks and after consultation with the Banks and the Borrower, appoint a successor Administrative Agent. Upon the acceptance by any person of its appointment as a successor Administrative
Agent, such person shall thereupon succeed to and become vested with all the rights, powers, privileges, duties and obligations of the retiring Administrative Agent, and the retiring Administrative Agent shall be discharged from its duties and
obligations as Administrative Agent under the Loan Documents. After any retiring Administrative Agent’s resignation as Administrative Agent, the provisions of this Article IX shall continue in effect for its benefit in respect of any
actions taken or omitted to be taken by it while it was acting as the Administrative Agent. 
 Section 9.07 Syndication Agent and
Documentation Agent. Neither the Syndication Agent nor the Documentation Agent shall have any rights, powers, obligations, liabilities, responsibilities or duties under the Loan Document other than those applicable to all Banks as such. Without
limiting the foregoing, neither of the Banks identified as “Syndication Agent” or “Documentation Agent” shall have or be deemed to have any fiduciary relationship with any Bank. Each of the Banks acknowledges that it has not
relied, and will not rely, on any of the Banks so identified in deciding to enter into this Agreement or in taking or not taking action hereunder.

including any indemnities and reimbursement obligations, made by the Borrower in the Loan Documents and in the certificates or other instruments prepared or delivered in connection therewith or pursuant thereto shall be considered to have been
relied upon by the Banks and shall survive the making by the Banks of the Loans and the execution and delivery to the Banks of any Notes evidencing such Loans, regardless of any investigation made by the Banks, or on their behalf, and shall continue
in full force and effect as long as the principal of or any accrued interest on any Loan or any Fee or any other amount payable under this Agreement or any other Loan Document is outstanding and unpaid and so long as the Commitments have not been

 Section 10.03 Binding Effect. This Agreement shall become effective when it shall have been executed by the Borrower
and the Administrative Agent and when the Administrative Agent shall have received copies hereof which, when taken together, bear the signatures of each Bank, and thereafter shall be binding upon and inure to the benefit of the Borrower, the
Administrative Agent and each Bank and their respective successors and permitted assigns. Whenever in this Agreement any of the parties hereto is referred to, such reference shall be deemed to include the successors and permitted assigns of such
party; and all covenants, promises and agreements by or on behalf of the Borrower, the Administrative Agent or the Banks that are contained in this Agreement shall bind and inure to the benefit of their respective successors and permitted assigns.

 Section 10.04 Successors and Assigns. 
 (a) Subject to Section 6.03, the Borrower may not assign or delegate any of its rights or duties under any of the Loan Documents without the prior written consent of each of the Banks. 
 (b) Each Bank (including the Administrative Agent when acting as a Bank) may assign to one or more assignees all or a portion of its
interests, rights and obligations under the Loan Documents (including all or a portion of its Commitment and the same portion of the applicable Loan or Loans at the time owing to it); provided, however, that (i) except in the case
of an assignment to a Bank or Affiliate of a Bank, the Borrower and the Administrative Agent must give their prior written consent to such assignment (which consents shall not be unreasonably withheld), provided that the consent of the
Borrower shall not be required if an Event of Default shall exist, (ii) no assignee of any Bank shall be entitled to receive any greater payment or protection under Section 2.11, 2.12(a) or 2.17 than such Bank would have been entitled to
receive with respect to the rights assigned or otherwise transferred unless such assignment or transfer shall have been made at a time when the circumstances giving rise to such greater payment did not exist, (iii) each such assignment shall be
of a constant, and not a varying, percentage of all the assigning Bank’s rights and obligations under this Agreement, (iv) the amount of the Commitment of the assigning Bank subject to each such assignment (determined as of the date the
Assignment and Assumption with respect to such assignment is delivered to the Administrative Agent) shall not be less than $5,000,000 (or, if less, the total amount of such Bank’s Commitment), (v) the parties to each such assignment shall
execute and deliver to the Administrative Agent an Assignment and Assumption and a processing and recordation fee of 

  

 53 








 
$3,500 and (vi) the assignee, if it shall not be a Bank, shall deliver to the Administrative Agent an Administrative Questionnaire. Upon acceptance and
recording pursuant to paragraph (d) of this Section 10.04, from and after the effective date specified in each Assignment and Assumption, which effective date shall be at least five Business Days after the execution thereof, (A) the
assignee thereunder shall be a party hereto and, to the extent of the interest assigned by such Assignment and Assumption, have the rights and obligations of a Bank under the Loan Documents and (B) the assigning Bank thereunder shall, to the
extent of the interest assigned by such Assignment and Assumption, be released from its obligations under the Loan Documents (and, in the case of an Assignment and Assumption covering all or the remaining portion of an assigning Bank’s rights
and obligations under the Loan Documents, such Bank shall cease to be a party hereto but shall continue to be entitled to the benefits of Sections 2.11, 2.13, 2.17 and 9.05, as well as to any Fees accrued for its account and not yet paid).

 (c) The Administrative Agent shall maintain a copy of each Assignment and Assumption delivered to it, including the
recordation of the names and addresses of the Banks, and the Commitment of, and principal amount of the Loans owing to, each Bank pursuant to the terms hereof from time to time (the “Register”). The Administrative Agent and
the Banks may treat each person whose name is recorded in the Register pursuant to the terms hereof as a Bank hereunder for all purposes of the Loan Documents. The Register shall be available for inspection by the Borrower and any Bank at any
reasonable time and from time to time upon reasonable prior notice. 
 (d) Upon its receipt of a duly completed Assignment and
Assumption executed by an assigning Bank and an assignee, an Administrative Questionnaire completed in respect of the assignee (unless the assignee shall already be a Bank hereunder), the processing and recordation fee referred to in paragraph
(b) above and, to the extent required, the written consent of the Borrower and the Administrative Agent to such assignment, the Administrative Agent shall (i) accept such Assignment and Assumption, (ii) record the information
contained therein in the Register and (iii) give prompt notice thereof to the Borrower. Upon the request of the assignee, the Borrower, at its own expense, shall execute and deliver to the Administrative Agent, a new Note or Notes to the order
of such assignee in a principal amount equal to the applicable Commitment assumed by it pursuant to such Assignment and Assumption and, if the assigning Bank has retained a Commitment, upon the request of the assigning Bank, the Borrower shall
execute and deliver a new Note to the order of such assigning Bank in a principal amount equal to the applicable Commitment retained by it. Canceled Notes shall be returned to the Borrower. 
 (e) Each Bank may without the consent of the Borrower or the Administrative Agent sell participations to one or more banks or other
entities in all or a portion of its rights and obligations under the Loan Documents (including all or a portion of its Commitment and the Loans owing to it and any Notes held by it); provided, however, that (i) such Bank’s
obligations under the Loan Documents shall remain unchanged, (ii) such Bank shall remain solely responsible to the other parties hereto for the performance of such obligations, (iii) the participating banks or other entities shall be
entitled to the benefit of the cost protection provisions contained in Sections 2.11, 2.13 and 2.17 to the same extent as if they were Banks (provided, that the amount of such benefit shall be limited to the amount in respect of the interest


  

 54 








 
sold to which the seller of such participation would have been entitled had it not sold such interest) and (iv) the Borrower, the Administrative Agent
and the Banks shall continue to deal solely and directly with such Bank in connection with such Bank’s rights and obligations under the Loan Documents, and such Bank shall retain the sole right to enforce the obligations of the Borrower
relating to the Loans and to approve any amendment, modification or waiver of any provision of the Loan Documents (other than amendments, modifications or waivers (A) decreasing any Fees or the amount of principal of or the rate at which
interest is payable on the Loans, (B) extending any scheduled date for the payment of Fees or principal of or interest on Loans, (C) extending the expiration date of the Commitments or (D) releasing the First Mortgage Bond or
releasing all or substantially all of the collateral therefor, in each such case except pursuant to Article VIII). 
 (f)
Any Bank or participant may, in connection with any assignment or participation or proposed assignment or participation pursuant to this Section 10.04, disclose to the assignee or participant or proposed assignee or participant any information
relating to the Borrower furnished to such Bank by or on behalf of the Borrower; provided that, prior to any such disclosure of information designated by the Borrower as confidential, each such assignee or participant or proposed assignee or
participant shall execute an agreement whereby such assignee or participant shall agree (subject to customary exceptions) to preserve the confidentiality of such confidential information. 
 (g) Notwithstanding anything to the contrary contained herein, any Bank (a “Granting Bank”) may grant to a
special-purpose funding vehicle (an “SPC”) the option to fund all or any part of any Loan that such Granting Bank would otherwise be obligated to fund pursuant to this Agreement; provided that (i) nothing herein
shall constitute a commitment by any SPC to fund any Loan, and (ii) if an SPC elects not to exercise such option or otherwise fails to fund all or any part of such Loan, the Granting Bank shall be obligated to fund such Loan pursuant to the
terms hereof. The funding of a Loan by an SPC hereunder shall utilize the Commitment of the Granting Bank to the same extent as if such Loan were funded by such Granting Bank. Each party hereto hereby agrees that no SPC shall be liable for any
indemnity or payment under the Loan Documents for which a Bank would otherwise be liable for so long as, and to the extent, the Granting Bank provides such indemnity or makes such payment. Notwithstanding anything to the contrary contained in this
Agreement, any SPC may disclose on a confidential basis any non-public information relating to its funding of Loans to any rating agency, commercial paper dealer or provider of any surety or guarantee to such SPC. This paragraph may not be amended
without the prior written consent of each Granting Bank, all or any part of whose Loans are being funded by an SPC at the time of such amendment. 
 (h) Any Bank may at any time assign for security purposes all or any portion of its rights under the Loan Documents to a Federal Reserve Bank; provided that no such assignment shall release a Bank from any of
its obligations thereunder.

 Section 10.05 Expenses; Indemnity, Damage Waiver. 
 (a) The Borrower agrees to pay all reasonable out-of-pocket expenses (including the reasonable fees, charges and disbursements of internal
or external legal counsel) (i) incurred by the Administrative Agent in connection with the preparation of the Loan Documents or in connection with any amendments, modifications or waivers of the provisions thereof (whether or not the
transactions thereby contemplated shall be consummated) or (ii) incurred by the Administrative Agent or any Bank in connection with the enforcement or protection of its rights in connection with the Loan Documents or any Loan. 
 (b) The Borrower agrees that it shall indemnify the Administrative Agent and the Banks against and hold them harmless from any documentary
taxes, assessments or charges made by any Governmental Authority by reason of the execution and delivery of this Agreement or any of the other Loan Documents. 
 (c) The Borrower agrees to indemnify the Administrative Agent and each Bank and each of their respective directors, officers, employees
and agents (each such person being called an “Indemnitee”) against, and to hold each Indemnitee harmless from, any and all losses, claims, damages, liabilities and related expenses, including reasonable counsel fees, charges
and disbursements, incurred by or asserted against any Indemnitee arising out of, in any way connected with, or as a result of, (i) the execution or delivery of this Agreement or any other Loan Document or any agreement or instrument
contemplated thereby, the performance by the parties thereto of their respective obligations thereunder or the consummation of the Transactions and the other transactions contemplated thereby, (ii) the use of the proceeds of the Loans or
(iii) any claim, litigation, investigation or proceeding relating to any of the foregoing, whether or not any Indemnitee is a party thereto; provided that such indemnity shall not, as to any Indemnitee, be available to the extent that
such losses, claims, damages, liabilities or related expenses are determined by a court of competent jurisdiction by final and nonappealable judgment to have resulted from the gross negligence or willful misconduct of such Indemnitee. 
 (d) To the fullest extent permitted by applicable law, the Borrower shall not assert, and hereby waives, any claim against any Indemnitee,
on any theory of liability, for special, indirect, consequential or punitive damages (as opposed to direct or actual damages) arising out of, in connection with, or as a result of, this Agreement, any other Loan Document or any agreement or
instrument contemplated hereby, the transactions contemplated hereby or thereby, any Loan or the use of the proceeds thereof; provided that such waiver shall not, as to any Indemnitee, apply to special, indirect or consequential damages to
the extent resulting from, or punitive damages awarded on account of, conduct by such Indemnitee that is determined by a court of competent jurisdiction by final and nonappealable judgment to have constituted gross negligence or willful misconduct
by such Indemnitee. 
 (e) The provisions of this Section 10.05 shall remain operative and in full force and effect
regardless of the expiration of the term of this Agreement, the consummation of the transactions contemplated hereby, the repayment of any of the Loans, the invalidity or unenforceability of any term or provision of this Agreement or any other Loan
Document, or any investigation made by or on behalf of the Administrative Agent or any Bank. All amounts due under this Section 10.05 shall be payable on written demand therefor. 
  

 56 








 Section 10.06 Right of Setoff. If an Event of Default shall have occurred and be continuing and
the Loans shall have been accelerated as set forth in Article VII, each of the Banks is hereby authorized at any time and from time to time, to the fullest extent permitted by law, to set off and apply any and all deposits (general or special,
time or demand, provisional or final) at any time held and other indebtedness at any time owing by such Bank (or person Controlling such Bank) to or for the credit or the account of the Borrower against any of and all the obligations of the Borrower
now or hereafter existing under this Agreement and other Loan Documents held by such Bank, irrespective of whether or not such Bank shall have made any demand under this Agreement or any other Loan Document and although such obligations of the
Borrower are owed to a branch or office of such Bank different from the branch or office holding such deposit or obligated on such indebtedness. The rights of each Bank under this Section are in addition to other rights and remedies (including
other rights of setoff) which such Bank may have. Any Bank shall promptly notify the Borrower after exercising its rights under this Section. 
 Section 10.07 Applicable Law. THIS AGREEMENT, AND THE OTHER LOAN DOCUMENTS OTHER THAN THE FIRST MORTGAGE BOND, THE FIRST MORTGAGE AND THE SUPPLEMENTAL INDENTURE, SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE LAWS OF THE
STATE OF NEW YORK. 
 Section 10.08 Waivers; Amendment. 
 (a) No failure or delay of the Administrative Agent or any Bank in exercising any power or right under the Loan Documents shall operate as
a waiver thereof, nor shall any single or partial exercise of any such right or power, or any abandonment or discontinuance of steps to enforce such a right or power, preclude any other or further exercise thereof or the exercise of any other right
or power. The rights and remedies of the Administrative Agent and the Banks hereunder and under the other Loan Documents are cumulative and are not exclusive of any rights or remedies which they would otherwise have. No waiver of any provision of
this Agreement or any other Loan Document or consent to any departure by the Borrower therefrom shall in any event be effective unless the same shall be permitted by paragraph (b) below, and then such waiver or consent shall be effective only
in the specific instance and for the purpose for which given. No notice or demand on the Borrower in any case shall entitle the Borrower to any other or further notice or demand in similar or other circumstances. 
 (b) Neither the Loan Documents nor any provision thereof may be waived, amended or modified except pursuant to an agreement or agreements
in writing entered into by the Borrower and the Required Banks; provided, however, that no such agreement shall (i) without the consent of the applicable Bank, (A) decrease the principal of or the rate of interest on such
Bank’s Loans or the Fees payable to such Bank, (B) extend the date for any scheduled payment of principal of or interest on such Bank’s Loans or the Fees payable to such Bank, or (C) increase the amount or extend the expiration
date of such Bank’s Commitment, or (ii) without the consent of each Bank, (A) release the First Mortgage Bond or release all or substantially all of the collateral therefor, in each such case except pursuant to Article VIII, or
(B) amend or modify the provisions of Section 2.14, the provisions of this Section, the definition of “Required Banks” or any other provision requiring the consent or agreement of each of the Banks; provided further
that no such agreement shall amend, modify or otherwise affect the rights or duties of the Administrative Agent under the Loan Documents without the prior written consent of the Administrative Agent. Each Bank and each holder of a Note shall be
bound by any 

  

 57 








 
waiver, amendment or modification authorized by this Section regardless of whether its Note shall have been marked to make reference thereto, and any
consent by any Bank or holder of a Note pursuant to this Section shall bind any person subsequently acquiring a Note from it, whether or not such Note shall have been so marked. 
 Section 10.09 Interest Rate Limitation. Notwithstanding anything herein or in any Notes to the contrary, if at any time the applicable interest
rate, together with all fees and charges which are treated as interest under applicable law (collectively the “Charges”), as provided for herein or in any other document executed in connection herewith, or otherwise
contracted for, charged, received, taken or reserved by any Bank, shall exceed the maximum lawful rate (the “Maximum Rate”) which may be contracted for, charged, taken, received or reserved by such Bank in accordance with
applicable law, the rate of interest payable under any Note held by such Bank, together with all Charges payable to such Bank, shall be limited to the Maximum Rate. 
 Section 10.10 Entire Agreement. Each Loan Document constitutes the entire contract between or among the parties relative to the subject matter thereof, and any previous agreement between or among the parties
with respect to the subject matter thereof is superseded by such Loan Document. Nothing in this Agreement or in the other Loan Documents, expressed or implied, is intended to confer upon any party other than the parties hereto and thereto any
rights, remedies, obligations or liabilities under or by reason of this Agreement or the other Loan Documents. 
 Section 10.11 Waiver of
Jury Trial. Each party hereto hereby waives, to the fullest extent permitted by applicable law, any right it may have to a trial by jury in respect of any litigation directly or indirectly arising out of, under or in connection with this
Agreement or any of the other Loan Documents. Each party hereto (a) certifies that no representative, agent or attorney of any other party has represented, expressly or otherwise, that such other party would not, in the event of litigation,
seek to enforce the foregoing waiver and (b) acknowledges that it and the other parties hereto have been induced to enter into this Agreement and the other Loan Documents, as applicable, by, among other things, the mutual waivers and
certifications in this Section 10.11. 
 Section 10.12 Severability. In the event any one or more of the provisions contained in
this Agreement or in any other Loan Document should be held invalid, illegal or unenforceable in any respect, the validity, legality and enforceability of the remaining provisions contained herein and therein shall not in any way be affected or
impaired thereby. The parties shall endeavor in good-faith negotiations to replace the invalid, illegal or unenforceable provisions with valid provisions the economic effect of which comes as close as possible to that of the invalid, illegal or
unenforceable provisions. 
 Section 10.13 Counterparts. This Agreement may be executed in two or more counterparts, each of which
shall constitute an original but all of which when taken together shall constitute but one contract, and shall become effective as provided in Section 10.03. 
  

 58 








 Section 10.14 Headings. Article and Section headings and the Table of Contents used
herein are for convenience of reference only, are not part of this Agreement and are not to affect the construction of, or to be taken into consideration in interpreting, this Agreement. 
 Section 10.15 Jurisdiction; Consent to Service of Process. 
 (a) The Borrower hereby irrevocably and unconditionally submits, for itself and its property, to the nonexclusive jurisdiction of any New
York State court or Federal court of the United States of America sitting in New York City, and any appellate court from any thereof, in any action or proceeding arising out of or relating to this Agreement or the other Loan Documents, or for
recognition or enforcement of any judgment, and each of the parties hereto hereby irrevocably and unconditionally agrees that all claims in respect of any such action or proceeding may be heard and determined in such New York State or, to the extent
permitted by law, in such Federal court. Each of the parties hereto agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided
by law. Nothing in this Agreement shall affect any right that the Administrative Agent or any Bank may otherwise have to bring any action or proceeding relating to this Agreement or the other Loan Documents against the Borrower or its properties in
the courts of any jurisdiction. 
 (b) The Borrower hereby irrevocably and unconditionally waives, to the fullest extent it
may legally and effectively do so, any objection which it may now or hereafter have to the laying of venue of any suit, action or proceeding arising out of or relating to this Agreement or the other Loan Documents in any New York State or Federal
court. Each of the parties hereto hereby irrevocably waives, to the fullest extent permitted by law, the defense of an inconvenient forum to the maintenance of such action or proceeding in any such court. 
 (c) Each party to this Agreement irrevocably consents to service of process in the manner provided for notices in Section 10.01.
Nothing in this Agreement will affect the right of any party to this Agreement to serve process in any other manner permitted by law. 
 Section 10.16 USA Patriot Act Notification. Each Bank hereby notifies the Borrower that, pursuant to the requirements of the USA Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001) (the
“Act”), it is required to obtain, verify and record information that identifies the Borrower, which information includes the name and address of the Borrower and other information that will allow such Bank to identify the

“Borrower”), hereby promises to pay to the order of
                             (the “Bank”), at the office of Union Bank of
California, N.A., as administrative agent (the “Administrative Agent”), at 445 South Figueroa Street, Los Angeles, California, on the Expiration Date, as defined in the Credit Agreement dated as of November 26, 2008

 The Borrower promises to pay interest, on demand, on any overdue principal and, to the extent permitted by law, overdue interest from their due dates at
the rate or rates provided in the Credit Agreement. 
 The Borrower hereby waives diligence, presentment, demand, protest and notice of any
kind whatsoever. The nonexercise by the holder of any of its rights hereunder in any particular instance shall not constitute a waiver thereof in that or any subsequent instance. 
 All Loans evidenced by this Note and all payments and prepayments of the principal hereof and interest hereon and the respective dates and maturity dates
thereof shall be endorsed by the holder hereof on the schedule attached hereto and made a part hereof or on a continuation thereof which shall be attached hereto and made a part hereof, or otherwise recorded by such holder in its internal records;
provided, however, that the failure of the holder hereof to make such a notation or any error in such a notation shall not affect the obligations of the Borrower under this Note. 
 This Note is one of the Notes referred to in the Credit Agreement, which, among other things, contains provisions for the acceleration of the maturity hereof upon the
happening of certain events, for optional and mandatory prepayment of the principal hereof prior to the maturity hereof and for the amendment or waiver of certain provisions of the Credit Agreement, all upon the terms and conditions therein
