 EXHIBIT A 
 TENANT FINISH-WORK: ALLOWANCE 
 1. Except as set forth

 2. Tenant will prepare space plans prepared by Tenant’s architect. Landlord shall have ten (10) days to provide comments and/or
approve the space plans. Upon approval, Tenant will obtain Working Drawings. Landlord shall provide an allowance of up to $1.50 per rentable square foot in the Premises (the “Working Drawings Allowance”) to be applied to expenses
related to the preparation of the space plans and Work Drawings and, in addition, any remaining amount may be applied to costs of the Work. Tenant shall select the architect, subject to Landlord’s prior written approval, not to be unreasonably
withheld or delayed. Payment of the Working Drawing Allowance shall be made to Tenant at the same time Tenant requests payment for the final one-half of the Construction Allowance provided Tenant has remitted to Landlord the Tenant Submittals. Any
unused portion of the Working Drawings Allowance remaining as of September 15, 2010 shall be forfeited by Tenant and remain Landlord’s property. As used herein, “Working Drawings” shall mean the final working drawings
approved by Landlord, as amended from time to time by any approved changes thereto, and “Work” shall mean all improvements to be constructed in accordance with and as indicated on the Working Drawings. Approval by Landlord of the
Working Drawings shall not be a representation or warranty of Landlord that such drawings are adequate for any use, purpose, or condition, or that such drawings comply with any applicable law or code, but shall merely be the consent of Landlord to
the performance of the Work. Tenant shall, at Landlord’s request, sign the Working Drawings to evidence its review and approval thereof. All changes in the Work must receive the prior written approval of Landlord, and in the event of any such
approved change Tenant shall, upon completion of the Work, furnish Landlord with an accurate, reproducible “as-built” plan (e.g., sepia) of the improvements as constructed, which plan shall be incorporated into this Lease by this reference
for all purposes. 
 3. The Work shall be performed only by contractors and subcontractors acceptable and approved by Landlord
in writing. All contractors and subcontractors shall be required to procure and maintain (a) insurance against such risks, in such amounts, and with such companies as Landlord may reasonably require; and (b) payment and performance bonds
covering the cost of the Work and otherwise reasonably satisfactory to Landlord. Certificates of such insurance, with paid receipts therefor, and copies of such bonds must be received by Landlord before the Work is commenced. The Work shall be
performed in a good and workmanlike manner that is free of defects and is in strict conformance with the Working Drawings, and shall be performed in such a manner and at such times as to maintain harmonious labor relations and not to interfere with
or delay Landlord’s other contractors, the operation of the Project, and the occupancy thereof by other tenants. All contractors and subcontractors shall contact Landlord and schedule time periods during which they may use Project facilities in
connection with the Work (e.g., loading docks, excess electricity, etc.).

 4. Tenant shall bear the entire cost of performing the Work (including, without limitation,
design of the Work and preparation of the Working Drawings, costs of construction labor and materials, electrical usage during construction, additional janitorial services, general tenant signage, related taxes and insurance costs, all of which
costs are herein collectively called the “Total Construction Costs”). 
 5. Provided Tenant is not in default
under the Lease, in addition to the Working Drawings Allowance, Landlord shall provide to Tenant a Construction Allowance in the amount up to $10.00 per rentable square foot in the Premises, one-half of which shall be applied as a credit against
Tenant’s Base Rental and the other one-half of which shall be reimbursed by Landlord to Tenant, all subject to the terms and conditions of this Exhibit A (“Construction Allowance”). Tenant shall be required to fund, at
its cost, the first one-half of the Construction Allowance (“Tenant Funds”). The Construction Allowance shall be used only for hard costs including, without limitation, installation of a back-up generator. In consideration of
Tenant’s advancement of the entire Tenant Funds and provided that Tenant is not in default under the Lease, as of the later to occur of: (a) the date Tenant advances the entire Tenant Funds and delivers to Landlord the Tenant Submittals or

Allowance shall be reimbursed in cash to Tenant by Landlord within sixty (60) days after Tenant has advanced the entire Construction Allowance and delivered to Landlord all of the Tenant Submittals. 
 In connection with the Work and as a condition precedent to any cash reimbursement and/or Base Rental credit Tenant shall submit Landlord
the following collectively (“Tenant Submittals”): (a) Tenant has substantially completed the Work (a certificate from the Architect) and obtained a certificate of occupancy, (b) photocopies of paid invoices evidencing that
the amount being requested has been paid by Tenant in connection with the Work, including without limitation, invoices from the architect, (c) Final Lien Waivers upon substantial completion of the Work in recordable form, fully executed and
acknowledged by Tenant’s general contractor and the subcontractors, suppliers and materialmen, indicating that upon the payment to the general contractor and the subcontractors, suppliers and materialmen of the amount set forth in such lien
waiver, the general contractor and the subcontractors, suppliers and materialmen waives and releases any and all liens or claims of liens they have owing to such party for all Work completed, and (d) a certificate from Tenant’s general
contractor that all subcontractors have been paid in full for all Work completed. Tenant shall be responsible and liable for timely paying all bills associated with the Work and agrees to indemnify and hold Landlord harmless (including reasonable
attorneys’ fees) from any claims related to the Work and will cause the removal of any lien recorded against the Building and/or the land upon which the Building is situated within ten (10) days following any such claim. If Tenant fails to
claim the Construction Allowance and/or fails to otherwise comply with the requirements of this section (including without limitation, Tenant’s failure to advance the Tenant Funds and/or provide the Tenant Submittals for either the Tenant Funds
and/or Construction Allowance) on or before September 15, 2010, Tenant shall not be entitled to any rent credit or cash reimbursement with respect to such Submittals, and that portion of the Construction Allowance relating thereto shall be deemed
forfeited and remain Landlord’s property.

 EXHIBIT B 
 EXTENSION OPTION 
 1. Provided that: (i) no default exists at the time
of such election, and (ii) Tenant is occupying the entire Premises at the time of such election, Tenant shall be permitted to renew this Lease for two (2) additional consecutive periods of five (5) years each on the same terms
provided in this Lease (except as set forth below), by delivering written notice of (“Tenant’s Notice”) the exercise thereof to Landlord not later than six (6) months prior to the end of the Term described in the Amendment
and with regard to the second option, six (6) months prior to the expiration as of the first five (5) year option. On or before the commencement date of the applicable extended Term, Landlord and Tenant shall execute an amendment to this
Lease extending the Term on the same terms provided in the Lease and this Addendum, except as follows: 
 (a) The Base Rent
payable for each month during each such extended Term shall be the prevailing market rental rate for buildings comparable to the Building, at the commencement of such extended Term, for space of equivalent class, quality, size and utility in the far
North Dallas/Addison submarkets (“Comparable Buildings”), with the length of the extended Term and the credit standing of Tenant to be taken into account, and with respect to the first five (5) year option, the Base Year shall
be adjusted at the end of the Term described in the Amendment to be the calendar year in which the renewal commences; 
 (b)
Tenant shall have no further renewal options unless expressly granted by Landlord in writing; 
 (c) any market concessions

notify Landlord in writing (“Tenant’s Renewal Notice”) of (i) Tenant’s exercise of its right to renew the Lease at the Base Rental rate proposed by Landlord, or (ii) Tenant’s election not to exercise its
right to renew the Lease. If Tenant fails to timely deliver Tenant’s Renewal Notice, such failure shall not be deemed acceptance by Tenant of the Base Rental rate proposed by Landlord, but Tenant shall be deemed to be a waiver of Tenant’s
right to an extended Term of the Lease and the Term. 
 3. Tenant’s rights under this Exhibit shall terminate if
(i) this Lease or Tenant’s right to possession of the Premises is terminated, (ii) Tenant assigns any of its interest in this Lease or sublets any portion of the Premises to a party other than a Related Entity, or (iii) Tenant
fails to timely exercise its option under this Exhibit, time being of the essence with respect to Tenant’s exercise thereof. Notwithstanding Subsection 3(ii) of the foregoing. Tenant’s rights under this Exhibit shall not terminate in the
event that Tenant assigns the Lease (as then amended) to any of Tenant’s parent, subsidiary or affiliated companies (“Related Entity”).

and/or fails to return the Amendment as required in this Exhibit C, then Landlord shall be free to lease the First Refusal Space and any additional space to the Prospect or any other party on such terms and conditions as Landlord deems

that funds may not be drawn from the Construction Fund held by the CA Trustee under the CA Indenture (the “CA Construction Fund”) unless certain conditions are met on
or before June 30, 2009. 
 D. The Original DPA was entered into in conjunction with the issuance of the CA Bonds and
the loan of the proceeds of the CA Bonds. Pursuant to each of the First Amendment, the Second Amendment, the Third Amendment, the Fourth Amendment, the Fifth Amendment, the Sixth Amendment, the Seventh Amendment, and the Eighth Amendment, among

been satisfied (the “Certificate”), then the CA Bondholders holding a majority in principal amount of the CA Bonds (the “CA Majority Bondholders”) may require the Company to purchase all of the
CA Bonds at a price of par plus accrued interest to the purchase date (the “DPA Demand Purchase”) by providing written notice on or before November 20, 2009 to the Company, EPC, the CA Trustee, and the other CA Bondholders

 F. The Company did not provide the CA Bondholders and the CA Trustee with the Certificate. 
 G. Accordingly, and without limitation, the CA Majority Bondholders currently have the outstanding right under the DPA to demand the DPA
Demand Purchase and to select the date of the DPA Demand Purchase, and the Company has the obligation under the DPA to purchase all of the CA Bonds at a price of par plus accrued interest to such purchase date.

stated in the following documents, the payment obligations ultimately evidenced by the CA Bonds and the TX Bonds are cross-guaranteed and cross-collateralized pursuant to, among other things, that Guarantee Agreement dated as of
October 1, 2006 and Supplemental Guarantee Agreement dated as of August 1, 2008, to which the Company and the Trustee, among others, are parties, and that Collateral Trust Agreement dated as of October 1, 2006 and Joinder to

Trustee to grant, certain concessions and forbearance with regard to the provisions of the DPA. 
 N. EPC has caused the Trustee

to be includable in gross income for federal income tax purposes, and (ii) the terms and provisions of this Restatement, including without limitation the Texas Purchase (defined below), will not in and of themselves cause interest on the TX
Bonds to be includable in gross income for federal income tax purposes. 
 O. The Bondholders have agreed, and have agreed to
direct the Trustee to agree, to the concessions and forbearance set forth in this Restatement, but only upon and subject to the terms and conditions expressly set forth herein, and subject to the conditions that the Borrower execute, deliver, and at

 P. The CSCDA has consented to the terms and provisions of this Restatement pertaining to
the CA Bonds. The GCIDA has consented to the terms and provisions of this Restatement pertaining to the TX Bonds. 
 NOW,
THEREFORE, in consideration of the foregoing, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Parties agree as follows: 
 1. Recitals. Each of the Company and EPC hereby confirms, represents and warrants to the Trustee and to each of the
Bondholders, upon which warranties and representations the Trustee and the Bondholders have relied in entering into this Restatement, the truth of the recitals set forth above. The recitals of this Restatement set forth above are incorporated herein
as an integral part of this Restatement. The Parties acknowledge that the Bondholders have relied upon the truth of such recitals in directing the Trustee to enter into this Restatement. 
 2. Redemption and Cancellation of 50% of the CA Bonds. 
 (a) The Company has determined and hereby agrees that it shall abandon either the Hanford Facility or the Riverdale Facility (as those
facilities are defined in the CA Loan Agreement) (such abandoned facility, the “Abandoned CA Facility”). For purposes of the CA Bond Documents, including without limitation Section 3.05 of the CA Loan Agreement, this
Restatement shall be deemed by each of the Company, EPC, CSCDA, the CA Trustee and the CA Bondholders to constitute an Abandonment Certificate (as defined in the CA Loan Agreement) with regard to the Abandoned CA Facility. On or before
December 18, 2009, the Company shall provide the Parties and CSCDA with a “Supplemental Abandonment Certificate,” in a form acceptable to the CA Trustee and the CA Bondholders, that shall supplement this Restatement, insofar as this
Restatement is deemed to constitute an Abandonment Certificate, and shall designate which of the Hanford Facility or the Riverdale Facility is the Abandoned CA Facility. In connection with the execution of this Restatement, the Company or EPC has
provided to bond counsel, i.e., counsel providing the opinion as to the CA Bonds described in Recital N above, information requested by such counsel concerning the use of the proceeds of the CA Bonds to the date hereof and the
expected use of such proceeds in the future. 
 (b) The CA Trustee shall cause fifty percent (50%) of the CA Bonds to
be redeemed and cancelled pursuant to, and in accordance with, Section 9.1(c)(ii) of the CA Indenture, in a manner such that fifty percent of the CA Bonds held by each CA Bondholder shall be redeemed

and cancelled (the “California Redemption”) at a price of par plus accrued interest to the date of redemption (the “CA Redemption Price”). Such date of
redemption shall be November 24, 2009, or as soon thereafter as is reasonably practicable in the discretion of the Trustee. The CA Redemption Price shall be funded from the funds and accounts held by the CA Trustee under the
CA Indenture, as follows: first, from the Debt Service Reserve Fund, fifty percent of the balance thereof; second, from the Capitalized Interest Account, the amount of the accrued interest included in the CA Redemption Price; and third,
from the CA Construction Fund, the remainder of the CA Redemption Price. The CA Trustee is hereby directed to immediately make the aforementioned transfers, and to hold such amounts in the Bond Fund established under the CA Indenture for the
sole and exclusive benefit of the CA Bondholders pending the California Redemption. If the ultimate CA Redemption Price is greater than the amount in such account, then the CA Trustee shall fund the difference from the CA Construction Fund. If
the ultimate CA Redemption Price is less than the amount in such account, then the CA Trustee shall refund the balance of such account to the CA Construction Fund. 
 (c) To the extent, if any, that written direction to the CA Trustee may be required to effectuate the California Redemption pursuant to, without limitation, the provisions of Section 5.02 of the CA
Loan Agreement and Section 9.1(c)(ii) of the CA Indenture, this Restatement shall constitute such written direction and the CA Trustee hereby acknowledges receipt thereof.

Bondholders to effectuate the California Redemption and the abandonment of the Abandoned CA Facility. 
 3. Redemption and
Cancellation of 25% of the TX Bonds. 
 (a) The TX Bondholders and the Company hereby direct the
TX Trustee to purchase and cancel twenty-five percent (25%) of the TX Bonds held by each TX Bondholder (the “Texas Purchase”) at a price of par plus accrued interest to the date of purchase (the “TX
Purchase Price”). Such date of purchase shall be November 24, 2009, or as soon thereafter as is reasonably practicable in the discretion of the Trustee. The TX Purchase Price shall be funded from the funds and accounts held
by the TX Trustee under the TX Indenture, as follows: first, from the Debt Service Reserve Fund, twenty-five percent of the balance thereof; and second, from the TX Construction Fund, the remainder of the TX Purchase Price. The TX
Trustee is hereby directed to immediately make the aforementioned transfers, and to hold such amounts in the Bond Fund established under the TX Indenture for the sole and exclusive benefit of the TX Bondholders pending the Texas Purchase. If the
ultimate TX Purchase Price is greater than the amount in such account, then the TX Trustee shall fund the difference from the TX Construction Fund. If the ultimate TX Purchase Price is less than the amount in such account, then the
TX Trustee shall refund the balance of such account to the TX Construction Fund.

TX Demand Purchase made pursuant to Subsection 8(b) below, which shall be no greater than the principal amount which may be purchased at the TX Purchase Price from amounts held in the funds and accounts held by the TX Trustee under the

(b) Upon receipt of the TX Demand Purchase Notice, and at the direction of the TX Majority Bondholders, the TX Trustee
shall make the “Initial TX Demand Purchase,” as follows: (i) the TX Trustee shall as soon as possible purchase the amount of TX Bonds described in Subsection 8(a)(ii) above, such purchase to be pro rata among the TX
Bondholders, and such purchase to be funded by amounts held in the funds and accounts held by the TX Trustee under the TX Indenture except for one-third of the balance of the Debt Service Reserve Fund and any amounts in the Rebate Fund;
(ii) the TX Trustee shall cause the amount representing the purchase price of such TX Bonds to be transferred to the TX Bondholders or to any account that the TX Bondholders designate in writing to the TX Trustee; and

(ii) any other amounts outstanding with regard to the TX Bonds or under the TX Indenture, including without limitation any fees and expenses of the TX Trustee or the TX Bondholders
incurred with regard to the TX Bonds, this Restatement, or the TX Bond Documents. The obligations stated in the preceding sentence are direct obligations of EPC. 
 (e) Until such time as the Second TX Demand Purchase takes place and all other amounts referenced in the preceding Subsection 8(d) are paid, the Unpurchased TX Bonds shall retain all of the benefits and
security of all of the TX Bond Documents and shall continue to accrue interest at their stated coupon rates. 
 9.
Payments. Any payments made by the Company or EPC hereunder shall be in immediately available funds. 
 10. No
Contingent Interest. 
 (a) By their execution of this Restatement, each of the Company and EPC acknowledges that the
funds and accounts held by the CA Trustee under the CA Indenture are held in trust for the benefit of the CA Bondholders. While the CA Construction Fund may be accessed for construction of Facilities pursuant to the CA Bond Documents, as
modified by this Restatement, so long as no Events of Default exist hereunder or under the CA Bond Documents, it is acknowledged and agreed that the CA Construction Fund will be used to repay the CA Bonds in the event that Events of
Default exist hereunder or under the CA Bond Documents, with regard to the California Redemption, or in the event that the CA Demand Redemption is required. Additionally, each of EPC and the Company acknowledge and agree that the Debt Service
Reserve Fund held under the CA Indenture is security for the CA Bondholders and that the only right the Company or EPC could have to amounts in such Debt Service Reserve Fund would arise from payment in full of the CA Bonds from amounts outside
such Debt Service Reserve Fund; accordingly, each of the Company and EPC acknowledges that it has no contingent interest in any of the funds and accounts held by the CA Trustee under the CA Indenture, each and all of which are ultimately and
solely the property of the CA Bondholders. 
 (b) By their execution of this Restatement, each of the Company and
EPC acknowledges that the funds and accounts held by the TX Trustee under the TX Indenture are held in trust for the benefit of the TX Bondholders. While the TX Construction Fund may be accessed for construction of Facilities pursuant to the TX

acknowledge and agree that the Debt Service Reserve Fund held under the TX Indenture is security for the TX Bondholders and that the only right the Company or EPC could have to amounts in such
Debt Service Reserve Fund would arise from payment in full of the TX Bonds from amounts outside such Debt Service Reserve Fund; accordingly, each of the Company and EPC acknowledges that it has no contingent interest in any of the funds and
accounts held by the TX Trustee under the TX Indenture, each and all of which are ultimately and solely the property of the TX Bondholders. 
 11. Waiver of Notice. By their execution of this Restatement, with regard to the California Redemption and the CA Demand Redemption, the CA Bondholders waive any redemption notice
requirements of the CA Indenture. By their execution of this Restatement, with regard to the Texas Purchase, and the TX Demand Redemption, the TX Bondholders waive any purchase or redemption notice requirements of the TX Indenture.

occurrence of which the Trustee and/or the Bondholders may proceed with any and all rights and remedies afforded by law, under this Restatement, under the CA Bond Documents, and/or under the TX Bond Documents, and/or otherwise available to the
Trustee and/or Bondholders:

time or the giving of notice would ripen into an Event of Default under any of the CA Bond Documents (without giving effect to the passage of time or giving of notice); 
 (b) the occurrence of any default, any Event of Default, or any event that with the passage of time or the giving of notice would ripen into an Event of Default under any of the TX Bond Documents (without
giving effect to the passage of time or giving of notice);

the payments due to Bondholders on account of the CA Bonds on December 1, 2009, the amount in the Bond Fund is insufficient for such purpose such that the CA Trustee draws upon the Debt Service Reserve Fund (“Bond Fund” and “Debt
Service Reserve Fund” both as defined in the CA Indenture); 
 (d) without any limitation to (b) above, if, with
regard to the payments due to holders of the TX Bonds on account of the TX Bonds on December 1, 2009, the amount in the Bond Fund is insufficient for such purpose such that the TX Trustee draws upon the Debt Service Reserve Fund (“Bond
Fund” and “Debt Service Reserve Fund” both as defined in the TX Indenture); 
 (e) without any limitation to
(a) or (b) above, if EPC, the Company, or any guarantor of any obligations of the Company, the CA Bonds, or the TX Bonds (i) petitions for relief, or has a petition for relief filed against it, under the United States

 EXHIBIT A 

 EXHIBIT “A” 
 TERMS OF BONDHOLDER INDEMNITY RELATED TO 
 DEMAND
PURCHASE AGREEMENT 
  

	 	Re:	$62,425,000 California Statewide Communities Development Authority Environmental Facilities Revenue Bonds (Microgy Holdings Project) Series 2008A (the
“Bonds”) 

 Each of the undersigned (collectively, the “Bondholders’” or
“us” or “we”) own the principal amount of the Bonds set forth next to its respective signature in that certain Demand Purchase Agreement, dated September 13, 2008 (“Demand Purchase Agreement”), among Microgy
Holdings LLC (“Microgy”), Environmental Power Corporation, Wells Fargo Bank, National Association (the “Trustee” or “you”) and the Bondholders. Capitalized terms not otherwise defined herein shall have the meanings
assigned to them in the Demand Purchase Agreement or that certain Trust Indenture (the “Indenture”), dated as of August 1, 2008, between the Trustee and California Statewide Communities Development Authority. 
 The Trustee has entered into the Demand Purchase Agreement at the direction of the Bondholders (the “Direction”) and has requested
that it be indemnified in Section 12 of the Demand Purchase Agreement for the consequences of actions taken by the Trustee thereunder. In the event that the Demand Purchase is exercised by the Majority Bondholder, in order to expedite the funds
transfer that will need to take place, the Trustee has requested that the terms of the indemnity be agreed to as of the date of the Demand Agreement and not at the time of the Demand Purchase. 
  

	1.	Definitions. 

 For purposes of this
Exhibit “A” and the terms of the indemnity set forth herein, the following definitions shall apply: 
 “Bond
Documents” shall refer to the Indenture, the Demand Purchase Agreement, the Loan Agreement, the Deeds of Trust, and all other such documents which ultimately secure the payment source for the Bonds 
 “Direction” shall mean the meaning set forth above. 
 “Extraordinary Charges and Expenses” shall mean your charges and out-of-pocket expenses (including reasonable
attorneys’ and paralegals’ fees, expenses and disbursements) reasonably and properly incurred by the Trustee in the course of taking any actions pursuant to the Direction, but shall not include Ordinary Fees and Expenses. 
 “Ordinary Fees and Expenses” shall mean regularly scheduled fees for services as Trustee under the Indenture and the
Trustee’s out-of-pocket expenses, incurred in performing such regularly scheduled services as set forth in Section 12.4 of the Indenture. 
 “Proportionate Share” shall mean the principal amount of the Bonds beneficially held by anyone of the Bondholders on the date of the Demand Purchase Agreement as a portion of the

  

 A-1 

 
aggregate principal amount of the Bonds beneficially held by all of the undersigned, subject to adjustment as provided in Paragraph 7 hereof. In other words, except as provided in Paragraph 7
hereof, each holders’ “Proportionate Share” when added together shall equal 100% and consequently cover 100% of any payments to be made hereunder. 
 “Reimbursement Claims” shall mean claims which the Trustee may have against Microgy or others or against certain collateral pursuant to the Indenture or other Bond Documents which provide
a source of payment to the Trustee for certain fees and expenses. 
 “Third-Party Liabilities” shall mean all
costs, claims, liabilities, losses or damages whatsoever (including reasonable fees, expenses and disbursements of the Trustee’s counsel reasonably incurred by you in connection therewith) asserted by third parties against you as a result of
your acting pursuant to the Direction, but shall not include Ordinary Fees and Expenses or Extraordinary Charges and Expenses. 
 “Trustee Lien” shall mean the lien which the Trustee has on certain of the funds and accounts held by the Trustee under the Indenture which provide a source of payment to the Trustee for certain fees and expenses under the
terms of the Indenture. 
  

	2.	Indemnity. 

 a. Subject to
the terms, conditions and limitations set forth below, the Bondholders hereby agree to indemnify the Trustee and save the Trustee harmless from all Ordinary Fees, Extraordinary Charges and Expenses and Third Party Liabilities incurred by the Trustee
in relation to the Direction, at any time from and after the date hereof during the period of your service as Trustee, in the performance of its powers and duties as Trustee under the Indenture, except for fees, charges, expenses, costs, claims,
losses, liabilities or damages incurred by the Trustee as a result of its own negligence or willful misconduct; without limiting the foregoing, nothing herein shall be taken to indemnify and save the Trustee harmless against any fees, charges,
expenses, costs, claims, losses, liabilities or damages based upon your acts or failures to act as Trustee which constitute breaches of its fiduciary duties or failures to execute properly its duties as Trustee. For the purposes of this paragraph,
any determination of whether or not the Trustee has engaged in willful misconduct or have been negligent or has breached its fiduciary duties as Trustee (or any like determination) shall be made by a court of competent jurisdiction on the basis of
the provisions contained in the Indenture (to the extent applicable). 
 b. The Bondholders’ Agreement to indemnify you as
set forth in this letter is also subject to the following limitations: 
  

	 	i.	The Trustee shall not be entitled to any indemnity from us for Extraordinary Charges and Expenses or Third Party Liabilities arising from or in connection with any
action taken without the Bondholders’ prior direction or consent (except any such action related to and reasonably necessary to implement a Direction, as directed by the Bondholders); and 

  

 A-2 

	 	ii.	The Trustee shall not be entitled to any indemnity from the Bondholders for Extraordinary Charges and Expenses or Third Party Liabilities paid or incurred by reason of
the Trustee’s failure to have trust powers or otherwise to be qualified or legally permitted to act as Trustee under the Indenture, unless the Trustee has appointed a co-Trustee under the Indenture that is qualified or legally permitted to act
under the Indenture and has so acted at the Trustee’s direction. 

  

	3.	Termination of Obligation. 

 Except as provided in the following sentence and subject to paragraph 8 hereof, it is understood and agreed that our obligation to indemnify you and save you harmless as Trustee as provided in this Agreement will terminate on the date upon
which the Bonds have been paid in full or the date the Bonds are canceled, whichever first occurs. Notwithstanding the foregoing sentence and subject to paragraph 8 hereof, our obligation to indemnify you shall continue until satisfied with respect
to Extraordinary Charges and Expenses or Third Party Liabilities accruing prior to the date on which the Bonds are paid in full or the date the Bonds are canceled, whichever first occurs. 
  

	4.	Notice of Claims; Control or Retention. 

 Promptly, upon your receipt of notice of any claim or of the commencement or threatened commencement of any action against you, which may constitute a Third Party Liability, you will cause notice to be
given to us in writing of such claim or such commencement or threatened commencement of an action, and will provide a copy of any documents received by you in connection therewith. In the event that any such claim or action shall be asserted against
you, you hereby agree that, at our request and at our sole discretion, you shall consent to our intervention in any such suit in order to defend against said claim and/or shall tender to us control of the defense and settlement of such clam or
action, and shall cooperate with us in such defense and settlement. We shall at all times have the right to employ counsel to represent both you and us in any claim or action described in this paragraph, whether or not we have requested intervention
or tender of control; provided that in the event such counsel determines that there is a conflict of interest between you and us and that you and we are not willing to waive such conflict or such counsel is unwilling to serve notwithstanding such
waiver, you shall be entitled to retain separate counsel (reasonably acceptable to us) whose reasonable fees and expenses shall constitute Extraordinary Charges and Expenses. Until we request the control of the defense and settlement of such claim
or action or unless we have otherwise employed counsel to represent both you and us, you shall have the right to employ your own counsel (reasonably acceptable to us) with respect to such claim or action, whose reasonable fees and expenses shall be
Extraordinary Charges and Expenses. Your giving notice and, if requested, tendering defense of the claims or actions required by this paragraph are conditions to our indemnification obligations hereunder. Further, we shall have no liability for any
settlement of any claim or action for which we otherwise agree herein to indemnify you unless notice of such proposed settlement shall have been furnished to us in accordance with this Agreement and we shall have consented to such settlement.

	5.	Payments. 

 a. We
understand that as provided in the Indenture or other Bond Documents you may have Reimbursement Claims and a Trustee Lien which provide sources of payment of some or all amounts covered by the indemnification provided by this Agreement. It is
understood and agreed that your Reimbursement Claims and Trustee Lien are the primary source of payment of such amounts and that our indemnification provided by this Agreement is a secondary source of payment. Therefore, prior to any payment by us
under this Agreement, you shall first assert your Reimbursement Claims and/or the Trustee’s Lien, until such time as the Trust Estate is depleted, unless we direct you otherwise and the exercise of the Trustee’s lien shall be a condition
to the Trustee’s right to indemnification hereunder. However, if funds are unavailable in the Trust Estate to make payments to you in a timely fashion, we will make such payments to you until such time as the Trust Estate is replenished. The
Trustee shall timely notify and consult with, and take direction from, the Bondholders regarding the preservation of such Reimbursement Claim. 
 b. If, under the circumstances as described in then foregoing paragraphs, you are entitled to an indemnification payment from us of an amount, we agree to pay to you within sixty (60) days of our
receipt of an invoice therefor, accompanied by such documentation supporting your entitlement to such amount as we may reasonably request. You agree to provide such invoices on a timely basis, and in no event less frequently than monthly. We further
agree that the then prevailing standard hourly rates of our counsel and other advisors selected with reasonable care and in accordance with the Bond Documents shall be deemed reasonable for purposes of this Agreement. In the event that we fail to
reimburse you in accordance with the provisions hereof within sixty (60) days after the date on which an invoice is received by us (unless and to the extent that payment of such invoice is being contested by us in good faith), interest will
accrue on the amounts due at the rate of interest announced by you as your “federal funds rate” in effect from time to time, from the sixty first (61st) day after such invoice is sent to us until payment has actually been received.

 c. If we make any payment to you hereunder we shall be automatically subrogated to your Reimbursement Claims and Trustee Lien
with respect to such payment, and, thereafter you shall not exercise any Reimbursement Claim or Trustee Lien with respect to such amount, except with our prior written consent. At our election, you shall also assign to us (to the extent assignable)
all such Reimbursement Claims and Trustee Lien. You agree, as a condition to your right of indemnification hereunder, to execute and deliver to us such assignments and other instruments as we shall reasonably determine to be necessary or advisable
to evidence such subrogation or assignment, which execution and delivery are conditions to your right of indemnification hereunder. In either event, however, upon our written request, you will diligently pursue all Reimbursement Claims and Trustee
Liens for our account as subrogee or assignee. Your reasonable out-of-pocket expenses and charges (including reasonable fees, expenses and disbursements of your counsel) incurred in connection with all such efforts shall constitute Extraordinary
Charges and Expenses and shall be covered by the indemnification hereunder. Such payments, if and when received by you, will be repaid to us, with interest, to the extent to which you have theretofore received payments or advances from us.

	6.	Several Liability. 

 Notwithstanding any other provision of this Agreement, it is agreed that the obligations of the undersigned are several and not joint, and that the obligation of each of the undersigned to pay any amount due to you hereunder shall not
exceed its respective Proportionate Share of such amount provided, however, that in no event shall the undersigned’s liability ever exceed the par amount of the Bonds held by it as of the date hereof. 
  

	7.	Transfer of Bonds. 

 In
the event that any of the undersigned should sell or otherwise dispose of all or a portion of their Bonds, our obligations to indemnify you hereunder shall automatically terminate with respect to the Bonds sold or disposed of and the transferring
Bondholder’s Proportionate Share shall be reduced accordingly (without increase of the Proportionate Share of the others). Such termination shall be prospective only, in that we shall have no obligation to indemnify or defend you for actions or
events which occur subsequent to the time of transfer. We shall remain obligated to indemnify, defend, and hold you harmless as set forth herein for claims, actions or events which have occurred or accrued prior to the date of the transfer of the
Bonds, except to the extent that such obligations are expressly assumed by the purchaser of such Bonds. 
  

	8.	Miscellaneous. 

 a. All
notices, demands and other communications hereunder shall be in writing and addressed to the parties hereto as follows: (1) if to you, at the address set forth in the Demand Purchase Agreement, and (2) if to us) at respective addresses set
forth on the signature pages to the Demand Purchase Agreement, or in either case to such other person(s) and address(es) as a party shall have specified in writing to the other. Notices, demands and other communications hereunder shall be effective
when received.
