accordance with the terms of the Indenture, a principal amount of Bonds, if any, then held under pledge equal to the principal amount of such prepayment. 
 (b) Prior to or simultaneously with the resale of Bonds acquired by the Trustee with the proceeds of one or more draws under the Letter of Credit, the Company shall prepay the then outstanding Tender Advances (in the
order in which they were made) by paying to the Bank an amount equal to the sum of (i) the portion of the purchase price corresponding to the aggregate principal amount of the Bonds being resold or to be resold, plus (ii) the portion of
the purchase price corresponding to the aggregate amount of accrued and unpaid interest on such Bonds, plus (iii) the aggregate amount of accrued and unpaid interest on such Tender Advances, less the amount paid pursuant to the immediately
preceding clause (ii). Such payment shall be applied by the Bank in reimbursement of such drawings (and as prepayment of Tender Advances resulting from such drawings in the manner described above), and, the Company irrevocably authorizes 

  

 10 








 
the Bank to reinstate the Letter of Credit in accordance therewith. In connection with a prepayment of Tender Advances from proceeds of the resale of Bonds,
the Company or its designee shall deliver notice to the Bank, prior to 11:30 A.M. (New York, New York time) on the date of such proposed prepayment, directing the Bank to deliver Bonds held by the Bank or its designee to the Remarketing Agent for
sale pursuant to the Indenture, and specifying the principal amount of Bonds to be sold, which notice may be given by telephone (promptly confirmed in writing). 
 (c) The Company agrees that, pursuant to the provisions of the Indenture, Bonds purchased with proceeds of a drawing under the Letter of
Credit shall be (i) registered by the Trustee in the name of the Bank and held by the Bank or its designee (including the Trustee), as agent and bailee of the Bank, expressly subject to the pledge in favor of the Bank, and deemed held by the
Trustee, as agent and bailee for the account of the Bank and (ii) in the event Bonds shall be certificated, held by the Trustee as agent and bailee for the account of the Bank or, at the Bank’s election, delivered by the Trustee to the
Bank or its designee. All such Bonds are to be held by the Bank or its agent, bailee or designee in pledge as collateral securing the Company’s payment obligations to the Bank hereunder as provided for in Section 2.14 hereof. Upon
payment to the Bank of the amount of such drawings, together with accrued interest, if required due to failure to pay such amounts on the date when due, on such amount, calculated at the Default Rate, to the date of payment, and upon written notice
to the Trustee that the Bank has reinstated the Letter of Credit, in an amount sufficient to cover all principal and accrued interest on the Bonds so released for up to 35 days at 12% per annum, with respect to Bonds purchased with proceeds of
such drawings, the Bank shall release, in accordance with the terms of the Indenture, a principal amount of Bonds, if any, then held under the pledge equal to the amount of such payment corresponding to the principal portion of such Bonds.

 Section 2.08 Increased Costs. If any law, regulation or change in any law or regulation or in the interpretation
thereof, or any ruling, decree, judgment, guideline, directive or recommendation (whether or not having the force of law) by any regulatory body, court, central bank or any administrative or governmental authority charged or claiming to be charged
with the administration thereof (including, without limitation, a request or requirement which affects the manner in which the Bank allocates capital resources to its commitments including its obligations hereunder) shall either (i) impose
upon, modify, require, make or deem applicable to the Bank or any of its affiliates, Subsidiaries or participants any reserve requirement, special deposit requirement, insurance assessment or similar requirement against or affecting the Letter of
Credit issued hereunder, or (ii) subject the Bank or any of its affiliates, Subsidiaries or participants to any tax, charge, fee, deduction or withholding of any kind whatsoever not in effect on the Date of Issuance in connection with the
Letter of Credit or change the basis of taxation of the Bank or any of its affiliates, Subsidiaries or participants (other than a change in the rate of tax based on the overall net income of the Bank or such participant), or (iii) impose any
condition upon or cause in any manner the addition of any supplement to or increase of any kind to the Bank’s or an affiliate’s, Subsidiary’s or participant’s capital or cost base for issuing or owning a participation in the
Letter of Credit which results in an increase in the capital requirement supporting the Letter of Credit from that in effect on the Date of Issuance, or (iv)

  

 11 








 
impose upon, modify, require, make or deem applicable to the Bank or any of its affiliates, Subsidiaries or participants any capital requirement, increased
capital requirement or similar requirement, such as the deeming of the Letter of Credit to be an asset held by the Bank or any of its affiliates, Subsidiaries or participants for capital adequacy calculation or other purposes (including, without
limitation, a request or requirement which affects the manner in which the Bank or any participant allocates capital resources to its commitments including its obligations hereunder or under the Letter of Credit), and the result of any events
referred to in (i), (ii), (iii) or (iv) above shall be to increase the costs in any way to the Bank or any affiliate, Subsidiary or participant of issuing, maintaining or participating in the Letter of Credit or reduce the amounts payable
by the Company hereunder or reduce the rate of return on capital, as a consequence of the issuing, maintaining or participating in the Letter of Credit, to a level below that which the Bank, its affiliates, Subsidiaries or participants could have
achieved but for such events; then and in such event the Company shall, promptly upon receipt of written notice to the Company by the Bank of such increased costs and/or decreased benefits, pay within 30 days of demand therefor to the Bank all such
additional amounts which, in the Bank’s or participant’s sole good faith calculation as allocated to the Letter of Credit, shall be sufficient to compensate it for all such increased costs and/or decreased benefits, all as certified by the
Bank or such participants in said written notice to the Company. Such certification shall be accompanied by information concerning the calculation of such increased costs and/or decreased benefits and shall be conclusive and binding on the parties
hereto, absent manifest error. In determining such amount, the Bank or any participant may use any reasonable averaging or attribution methods. 
 Section 2.09 Payments and Computations. The Company shall make each payment hereunder (a) representing reimbursement pursuant to Section 2.04 hereof to the Bank immediately after payment by the Bank of
drawings made under the Letter of Credit (and before 3:30 p.m. (New York, New York time) on the same Business Day of the Bank’s payment of such drawing), and (b) not later than 2:00 p.m. (New York, New York time) for all other payments, on
the day when due in lawful money of the United States of America to the Bank at its address referred to in Section 7.02 hereof in same day funds. The Company hereby authorizes the Bank, if and to the extent payment is not made when due
hereunder, to charge from time to time against any of the Company’s respective accounts with the Bank, any amount so due. Computations of any fees or commissions hereunder shall be made by the Bank on the basis of a year of 360 days for the
actual number of days (including the first day but excluding the last day) elapsed. Whenever any payment to be made hereunder shall be stated to be due on a day which is not a Business Day, such payment shall be made on the next succeeding Business
Day and such extension of time shall in such case be included in the computation of payment of interest, fee or commission, as the case may be. 
 Section 2.10 Evidence of Debt. The Bank shall maintain in accordance with its usual practice an account or accounts evidencing the indebtedness of the Company resulting from each drawing under the Letter of Credit and
each Tender Advance made from time to time hereunder and the amounts of principal, interest and fees payable and paid from time to time hereunder. In any legal action or proceeding in respect of this Agreement, the entries made in such account or
accounts shall be conclusive evidence of the existence and amounts of the obligations of the Company therein recorded, absent manifest error. 
  

 12 








 Section 2.11 Obligations Absolute. The payment obligations of the Company under this
Agreement shall be unconditional and irrevocable, and shall be paid strictly in accordance with the terms of this Agreement under all circumstances, including, without limitation, the following circumstances: 
 (a) any lack of validity or enforceability of the Bonds, the Indenture, the Loan Agreement, the First Mortgage Bond, the First Mortgage
Supplemental Indenture or any other agreement or instrument relating thereto (collectively, together with the Letter of Credit, the “Related Documents”); 
 (b) any amendment or waiver of or any consent to departure from all or any of the Related Documents; 
 (c) the existence of any claim, set-off, defense or other right which the Company may have at any time against the Trustee or any other
beneficiary, or any transferee, of the Letter of Credit (or any Persons or entities for whom the Trustee, any such beneficiary or any such transferee may be acting), the Bank or any other Person or entity, whether in connection with this Agreement,
the transactions contemplated herein or in the Related Documents, or any unrelated transaction; and 
 (d) any statement or
any other document presented under the Letter of Credit proving to be forged, fraudulent, invalid or insufficient in any respect or any statement therein being untrue or inaccurate in any respect. 
 Section 2.12 Payment with Bank’s Funds. The Bank agrees that any and all payments made under the Letter of Credit will be made
with the Bank’s own funds. 
 Section 2.13 Extension of the Stated Termination Date. Not fewer than 90 days before
the Stated Termination Date, the Company may request the Bank in writing to extend the Stated Termination Date for purposes of this Agreement and the Letter of Credit. If the Company shall make such a request, the Bank shall, within 30 days of
receiving such written request, notify the Company in writing whether or not the Bank will extend the Stated Termination Date and, if the Bank does so elect, the conditions of such extension (including conditions relating to legal documentation and
pricing, such as fees for renewal and drawings). If the Bank shall not so notify the Company, the Bank shall be deemed to have not consented to such request. All requests and notices made pursuant to this Section 2.13 shall also be
delivered to the Trustee. 
 Section 2.14 Pledged Bonds. The Company hereby pledges, assigns, hypothecates, transfers and
delivers to the Bank all its right, title and interest to, and hereby grants to the Bank a first lien on, and security interest in, all right, title and interest of the Company in and to the following (the “Collateral”): 
 (a) all Bonds which may from time to time have been purchased with proceeds of C Drawings under the Letter of Credit (the “Pledged
Bonds”); 
  

 13 








 (b) all income, earnings, profits, interest, premium or other payments in whatever form
in respect of the Pledged Bonds; and 
 (c) all proceeds (cash and non-cash) arising out of the sale, exchange, collection,
enforcement or other disposition of all or any portion of the Pledged Bonds; 
 as collateral security for the prompt and complete payment when due of all
amounts due in respect of the reimbursement obligations of the Company set forth herein with respect to such Pledged Bonds (the “Obligations”). 
 Pledged Bonds shall be held by the Trustee pursuant to the provisions of the Indenture or as otherwise directed by the Bank. 
 In the event that the Company shall fail to pay any amount when due hereunder with respect to the Pledged Bonds, the Bank, without demand of performance or other demand, advertisement or notice of any kind (except the
notice specified below of time and place of public or private sale or except as may be required by applicable law) to or upon the Company or any other Person (all and each of which demands, advertisements and/or notices are hereby expressly waived),
may forthwith collect, receive, appropriate and realize upon the Collateral, or any part thereof, and/or may forthwith sell, assign, give option or options to purchase, contract to sell or otherwise dispose of and deliver said Collateral, or any
part thereof, in one or more parcels at public or private sale or sales, at any exchange, broker’s board or at any of the Bank’s offices or elsewhere upon such terms and conditions as it may deem advisable and at such prices as it may deem
best, for cash or on credit or for future delivery without assumption of any credit risk, with the right of the Bank upon any such sale or sales, public or private, to purchase the whole or any part of said Collateral so sold, free of any right or
equity of redemption in the Company, which right or equity of redemption is hereby expressly waived or released. The Bank will notify any purchasers of Pledged Bonds that the Letter of Credit will not be available with respect to the Pledged Bonds
and, therefore, the ratings assigned by any rating agency, including Moody’s Investors Service, Inc., will not apply. The Bank shall apply the net proceeds of any such collection, recovery, receipt, appropriation, realization or sale, after
deducting all reasonable costs and expenses of every kind incurred therein or incidental to the care, safekeeping or otherwise of any and all of the Collateral or in any way relating to the rights of the Bank hereunder, including reasonable
attorneys’ fees and legal expenses, to the payment in whole or in part of the Obligations in such order as the Bank may elect, the Company remaining liable for any deficiency remaining unpaid after such application, and only after so applying
such net proceeds and after the payment by the Bank of any other amount required by any provision of law, need the Bank account for the surplus, if any, to the Company. The Company agrees that the Bank need not give more than ten days’ notice
of the time and place of any public sale or of the time after which a private sale or other intended disposition is to take place and that such notice is reasonable notification of such matters. No notification need be given to the Company if it has
signed after default a statement renouncing or modifying any right to notification of sale or other intended disposition. In addition to the rights and remedies granted to it in this Agreement and in any other instrument or agreement securing,
evidencing or relating to any of the Obligations, the Bank shall have all the rights and remedies of a secured party under the 

  

 14 








 
Uniform Commercial Code of the State of Washington, except to the extent the remedial provisions of some other state laws are applicable. 
 The Company covenants that the pledge, assignment and delivery of the Collateral hereunder will create a valid, perfected, first priority security
interest in all right, title or interest of the Company in or to such Collateral, and the proceeds thereof, subject to no prior pledge, lien, mortgage, hypothecation, security interest, charge, option or encumbrance or to any agreement purporting to
grant to any third party a security interest in the property or assets of the Company which would include the Collateral. The Company covenants and agrees that it will defend the Bank’s right, title and security interest in and to the
Collateral and the proceeds thereof against the claims and demands of all persons whomsoever. 
 Pledged Bonds shall be released from the
security interest created hereunder upon satisfaction of the Obligations with respect to such Pledged Bonds, and restoration of the Letter of Credit in the amount of any drawing thereunder to satisfy the Obligations.

drawn under the Letter of Credit or (ii) the conversion of interest rate on the Bonds from the Daily Interest Rate (as defined in the Indenture).

shall be immediately due and payable without presentment, demand, protest or other notice of any kind, all of which are hereby waived by the Company; provided, however, the Bank is not limited in its remedies if the Bank fails to notify the Company
of acceleration under this Section 6.02(a); or 
 (b) Enforcement of Rights. Enforce any and all rights and
interests created and existing hereunder or under any of the other Related Documents and all rights of set-off; or 
  

 22 








 (c) Draw on Letter of Credit. The Bank may, at its option, direct the Trustee to
(i) accelerate the principal and interest due on the Bonds and to draw on the Letter of Credit, in accordance with Section 9.01(g) of the Indenture; or (ii) direct a mandatory purchase of the Bonds in accordance with
Section 3.02(a)(v) of the Indenture. If the Bonds are purchased rather than redeemed with the proceeds of such a drawing under the Letter of Credit, such Bonds shall be held as Pledged Bonds for the benefit of the Bank in accordance with the
terms hereof and of the terms of the Indenture. 
 Notwithstanding the foregoing, if a default under Sections 6.01(h) shall occur,
then all obligations, all accrued interest in respect thereof, all accrued and unpaid fees and other indebtedness or obligations owing to the Bank hereunder shall immediately become due and payable without the giving of any notice or other action by
the Bank. 
 Section 6.03 No Remedy Exclusive. No remedy herein conferred upon or reserved to the Bank is intended to be
exclusive of any other available remedy or remedies, but each and every such remedy shall be cumulative and shall be in addition to every other remedy given hereunder, under the Loan Agreement, the Indenture, or the other Related Documents, or now
or hereafter existing at law or in equity or by statute. 
 Section 6.04 Anti-Marshalling Provisions. The right is hereby
given by the Company to the Bank to make releases (whether in whole or in part) of all or any part of the Bank’s security without notice to, or the consent, approval or agreement of other parties and interests, including junior lienors (to the
extent the Company has such right), which releases shall not impair in any manner the validity of or priority of the liens and security interest in the remaining collateral conferred under such documents, nor release the Company from liability for
the obligations hereby secured. Notwithstanding the existence of any other security interest in the collateral held by the Bank, the Bank shall have the right to determine the order in which any or all of the collateral shall be subjected to the
remedies provided herein or in the Indenture. The Company hereby waives any and all right to require the marshalling of assets in connection with the exercise of any of the remedies permitted by applicable law or provided herein or therein.

 Section 6.05 Subrogation. If an Event of Default shall have occurred and be continuing and there shall be outstanding
all or any part of any unreimbursed Letter of Credit payment(s) or any other obligation hereunder, the Company agrees that the Bank shall be subrogated to any and all rights of the Company against the beneficiary of the Letter of Credit, and the
Company agrees that, upon request of the Bank, the Company will promptly do such further acts and execute, acknowledge and deliver such documents as the Bank may reasonably request in order to implement the assignment to the Bank of such rights of
the Company against the beneficiary of the Letter of Credit.

 Section 7.05
Indemnification. The Company hereby indemnifies and holds the Bank harmless from and against any and all claims, damages, losses, liabilities, costs or expenses which the Bank may incur or which may be claimed against the Bank by any

after the presentation to it by the Trustee of a draft and certificate strictly complying with the terms and conditions of the Letter of Credit. 
 Nothing in this Section 7.05 is intended to limit the Company’s obligations contained in Article II. Without prejudice to the survival of any other obligation of the Company hereunder, the indemnities and obligations of the
Company contained in this Section 7.05 shall survive the payment in full of amounts payable pursuant to Article II and the termination of the Letter of Credit for the period ending on the last day of the applicable statute of limitations
period. 
 Section 7.06 Liability of the Bank. The Company assumes all risks of the acts or omissions of the Trustee and
any other beneficiary or transferee of the Letter of Credit with 

  

 25 








 
respect to its use of the Letter of Credit. Neither the Bank nor any of its officers or directors, in its or their capacity as letter of credit bank, shall
be liable or responsible for: (a) the use which may be made of the Letter of Credit or any acts or omissions of the Trustee and any other beneficiary or transferee in connection therewith; (b) the validity, sufficiency or genuineness of
documents, or of any endorsement thereon, even if such document should prove to be in any or all respects invalid, insufficient, fraudulent or forged; (c) payment by the Bank against presentation of documents which do not comply with the terms
of the Letter of Credit, including failure of any documents to bear any reference or adequate reference to the Letter of Credit; or (d) any other circumstances whatsoever in making or failing to make payment under the Letter of Credit, except
that the Company shall have a claim against the Bank, and the Bank shall be liable to the Company, to the extent of any direct, as opposed to consequential, damages, suffered by the Company which the Company proves were caused by the Bank’s
(i) gross negligence or willful misconduct in determining whether documents presented under the Letter of Credit complied with the terms of the Letter of Credit or (ii) wrongful failure to make lawful payment under the Letter of Credit
after the presentation to it by the Trustee of a draft and certificate strictly complying with the terms and conditions of the Letter of Credit. In furtherance and not in limitation of the foregoing, the Bank may accept documents that appear on
their face to be in order, without responsibility for further investigation, regardless of any notice or information to the contrary. 
 Section 7.07 Costs, Expenses and Taxes. The Company agrees to pay immediately when due all costs and expenses in connection with the preparation, execution, delivery, filing, recording, and enforcement of this Agreement

thereafter shall be binding upon and inure to the benefit of the Company and the Bank and their respective successors and assigns, except that the Company shall not have the right to assign its rights hereunder or any interest herein without the
prior written consent of the Bank. The Bank may, without cost or expense to the Company, assign or sell a participation in all or any part of, or any interest (undivided or divided) in, the Bank’s rights and benefits under this Agreement to any
financial institution, giving the first option to participate to the parties of the Credit Agreements; provided that, with respect to a participation, after giving effect to any such sale of a participation, the Bank shall remain obligated to honor
draws on the Letter of Credit with its own funds. To the extent of any 

  

 26 








 
assignment by the Bank, the assignee shall have the same rights and benefits against the Company hereunder as it would have had if such assignee were the
Bank issuing or paying under the Letter of Credit hereunder. 
 Section 7.09 Severability. Any provision of this Agreement
which is prohibited, unenforceable or not authorized in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition, unenforceability or non-authorization without invalidating the remaining provisions hereof or

Remarketing Agent 30 days prior, where reasonable, and not more than 30 days subsequent to the consummation of any transaction that would result in the Company controlling or being controlled by the Bank. The Bank acknowledges that the foregoing
sentence supersedes any exemptions from the continuing disclosure requirement pursuant to Rule 15c2-12(b)(5) of the Securities Exchange Act of 1934. 
 Section 7.13 Prior Agreements Superseded. This Agreement shall completely and fully supersede all prior undertakings or agreements, both written and oral, between the Company and the Bank relating
to the issuance of the Letter of Credit, including those contained in any commitment letter between the Bank and the Company executed in anticipation of the issuance of the Letter of Credit, except for any provisions in such commitment letter which
by their express terms survive issuance of the Letter of Credit. 
 Section 7.14 Waiver of Jury Trial. 
 THE BANK AND THE COMPANY HEREBY KNOWINGLY, VOLUNTARILY AND INTENTIONALLY WAIVE ANY RIGHTS THEY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION
BASED HEREON, OR ARISING OUT OF, UNDER OR IN CONNECTION WITH, THIS AGREEMENT, OR ANY COURSE OF CONDUCT, COURSE OF DEALING, STATEMENTS (WHETHER ORAL OR WRITTEN), OR ACTIONS OF THE BANK OR THE COMPANY. THIS PROVISION IS A MATERIAL INDUCEMENT FOR THE
BANK ENTERING INTO THIS AGREEMENT.

thereafter reinstated as hereinafter provided, the “Stated Amount”), consisting of (i) the amount of $17,000,000 (as reduced and thereafter reinstated from time to time as hereinafter provided, the “Principal

“Maximum Rate”), as certified to us, in your favor for the benefit of the holders of the herein described Bonds, as Trustee under that certain Trust Indenture, dated as of December 1, 2008 (the “Indenture”), by
and between you, as Trustee, and the City of Forsyth, Montana (the “Issuer”), pursuant to which the Issuer has issued $17,000,000 in aggregate principal amount of its Pollution Control Revenue Refunding Bonds (Avista Corporation

 Subject to the other provisions of this Letter of Credit, you or your transferee may obtain the funds available under this Letter of Credit by presentment to us of your sight draft or drafts drawn on Bank of America,

 2. Annex B (Principal and Interest Demand Without Reinstatement Request). If you are demanding funds with respect to the payment of

However, in the case of a draft or drafts accompanied by your certification substantially in the form of Annex A and presented in full compliance with the
terms and conditions of this Letter of Credit, the Stated Amount of this Letter of Credit shall, on the date each draft is honored by us, automatically be reinstated by us, by an amount equal to the amount of that Drawing; after such reinstatement,

regard to the provisions of this sentence) and able to do so. 
 By paying you an amount demanded in accordance with this Letter of Credit,
we make no representation as to the correctness of the amount demanded or your calculations and representations on the certificates required of you by this Letter of Credit.

 This Letter
of Credit sets forth in full our undertaking, and such undertaking shall not in any way be modified, amended, amplified or limited by reference to any document, instrument or agreement referred to herein (including, without limitation, the Bonds),
