 REVOLVING NOTE 
  

			
	$10,000,000.00	  	McLean, Virginia
		  	Effective April 30, 2007

 FOR VALUE RECEIVED, Integral Systems, Inc.,
a Maryland corporation (“Integral”), SAT Corporation, a California corporation (“SAT”), Newpoint Technologies, Inc., a Delaware corporation (“NTI”), Real Time Logic, Inc., a Colorado corporation (“RTL”), and
Lumistar, Inc., a Maryland corporation (“Lumistar”, and together with Integral, SAT, NTI and RTL, collectively and individually, and jointly and severally, the “Borrower”), having an address at 5000 Philadelphia Way, Suite A,
Lanham, Maryland 20706, jointly and severally promise to pay to the order of Bank of America, N.A. (the “Lender”), at 1101 Wootton Parkway, 4th Floor, MD9-978-04-01, Rockville, Maryland 20852 or such other address as Lender may designate, the principal sum of Ten Million and No/100 Dollars ($10,000,000.00) (the “Principal Sum”), or
so much thereof as has been or may be advanced or readvanced to or for the account of the Borrower pursuant to the terms and conditions of the “Loan Agreement” (as hereinafter defined), together with interest thereon at the rate or rates
hereinafter provided, in accordance with the following terms. This Amended and Restated Revolving Note, as the same may be amended from time to time, is referred to herein as the “Note”. Subject to the terms and provisions of this Note and
the Loan Agreement, amounts repaid or prepaid hereunder may be reborrowed. Capitalized terms used herein and not otherwise defined herein shall have the meanings ascribed thereto in the Loan Agreement. 
 This Note amends and restates in its entirety that certain Revolving Note, dated as of August 31, 2001, in the original principal amount of Ten
Million and No/100 Dollars ($10,000,000.00), executed by Integral and SAT and payable to the order of Lender, as amended by that certain First Amendment to Revolving Note, dated as of February 25, 2004, as further amended by that certain Second
Amendment to Revolving Note, dated as of January 19, 2005, as further amended by that certain letter from Lender to Integral dated February 20, 2007, and as further amended by that certain Fourth Amendment to Revolving Note, dated as of
March 30, 2007 (the “Original Note”). This Note is not a novation of the Original Note. 
 1. Interest.
Commencing as of the date hereof and continuing until repayment in full of all sums due hereunder, the unpaid Principal Sum shall bear interest at a fluctuating rate, determined as follows: Interest on the principal balance outstanding from time to
time shall accrue at a fluctuating annual rate equal to the “LIBOR Market Index Rate” (hereinafter defined) in effect from time to time plus 150 percentage points (15%). The LIBOR Market Index Rate, for any day, is the rate for 1 month
U.S. dollar deposits as reported on Telerate page 3750 as of 11:00 a.m., London time, on such day, or if such day is not a London business day, then the immediately preceding London business day (or if not so reported, then as determined by Lender
from another recognized source or interbank quotation). Absent manifest error, the Lender’s determination of the LIBOR Market Index Rate for any day shall be conclusive. 

 The rate of interest that shall accrue under this Note shall change immediately upon any change in the
LIBOR Market Index Rate. 
 All interest payable under the terms of this Note shall be calculated by applying a daily interest rate,
determined by multiplying the outstanding principal balance by the applicable annual interest rate and dividing the resulting product by 360, to the actual number of days principal is outstanding. 
 2. Payments and Maturity. The unpaid Principal Sum, together with interest thereon at the rate or rates provided above, shall be payable as
follows: 
 a. interest shall be due and payable monthly, commencing on the last day of the first calendar month commencing
after the date of this Note, and on the last day of each succeeding calendar month. 
 b. unless sooner paid, the unpaid
Principal Sum, together with all interest accrued and unpaid thereon, and all other amounts owing under this Note shall be due and payable in full on February 28, 2010 (the “Maturity Date”). If the Loan Agreement provides for the
Borrower to make additional payments on account of the Principal Sum from time to time, Borrower promise to make those payments at the time and in the manner specified in the Loan Agreement. 
 This Note evidences the Borrower’s joint and several promise to repay advances and readvances under the Loan Agreement. This Note will continue in full force and
effect and will evidence Borrower’s obligation to repay such advances and readvances notwithstanding that the principal amount outstanding under the Loan Agreement and evidenced by this Note may be reduced to zero from time to time. 

3. Default Interest. Upon the occurrence of an Event of Default (as hereinafter defined), unless otherwise required by law, the Lender
shall be entitled to interest on the unpaid balance at a rate of five percent (5%) above Lender’s “Prime Rate” of interest, being that rate of interest announced by the Lender from time to time as being its Prime Rate, in its
sole discretion. 
 4. Late Charges. If the Borrower fails to make any payment under the terms of this Note within ten
(10) days after the date such payment is due, the Borrower shall pay to the Lender on demand a late charge equal to five percent (5%) of such payment. 
 5. Application and Place of Payments. Except as otherwise provided in the Loan Agreement (hereinafter defined), all payments, made on account of this Note shall be applied first to the payment of accrued
and unpaid interest then due hereunder, second to the unpaid principal balance and the remainder, if any, shall be applied to any other amounts which remain owing hereunder. All payments on account of this Note shall be paid in lawful money of the
United States of America in immediately available funds during regular business hours of the Lender at its office at 

  

 2 

 
8300 Greensboro Drive, Suite 550, McLean, Virginia 22102-3604, or at such other times and places as the Lender may at any time and from time to time
designate in writing to the Borrower. 
 6. Loan Agreement. This Note is governed by additional terms and conditions contained
in that certain Amended and Restated Revolving Line of Credit Loan and Security Agreement, dated as of the date hereof, by and among the Borrower and the Lender (said Amended and Restated Revolving Line of Credit Loan and Security Agreement, as the
same may be amended from time to time, is referred to herein as the “Loan Agreement”). The indebtedness evidenced by this Note is included within the meaning of the term “Debt” (as defined in the Loan Agreement). The Loan
Agreement amends and restates in its entirety that certain Amended and Restated Revolving Line of Credit Loan Agreement and Security Agreement, dated as of August 31, 2001, by and among Integral, SAT and Lender, as amended by that certain First
Modification to Amended and Restated Revolving Line of Credit Loan Agreement and Security Agreement, dated as of February 3, 2003, as further amended by that certain Second Amendment to Amended and Restated Revolving Line of Credit Loan
Agreement and Security Agreement, dated as of February 25, 2004, and as further amended by that certain Third Amendment to Amended and Restated Revolving Line of Credit Loan Agreement and Security Agreement, dated as of January 19, 2005.

 7. Security. This Note is secured by the Collateral described in the Loan Agreement. 
 8. Events of Default. The occurrence of any one or more of the following events shall constitute an event of default (individually, an
“Event of Default” and collectively, the “Events of Default”) under this Note: 
 a. the failure of the
Borrower to pay to the Lender, when due, any amount payable by the Borrower to the Lender under the terms of this Note; or 
 b. the occurrence of an event of default under any of the other Loan Documents. 
 9. Remedies. Upon the occurrence of
an Event of Default, at the option of the Lender, all principal, accrued interest and other sums payable by the Borrower to the Lender under the terms of this Note shall become immediately due and payable, and the Lender shall have all of the
rights, powers, and remedies available under the terms of this Note, any of the other Loan Documents and all applicable laws. The Borrower and all endorsers hereby jointly and severally waive presentment, protest and demand, notice of protest,
notice of demand and of dishonor and non-payment of this Note and expressly agree that this Note or any payment hereunder may be extended from time to time without in any way affecting the liability of the Borrower or any endorsers. 
 10. Expenses. The Borrower promises to pay to the Lender on demand by the Lender all reasonable costs and expenses incurred by the Lender
in connection with the collection and enforcement of this Note, including, without limitation, all reasonable attorneys’ fees and expenses, all court costs and all arbitration fees and costs. 
  

 3 

 11. Notices. Any notice, request, or demand to or upon Borrower or the Lender shall be
deemed to have been properly given or made when delivered in accordance with the Loan Agreement. 
 12. Miscellaneous. Each
right, power, and remedy of the Lender as provided for in this Note or any of the other Loan Documents, or now or hereafter existing under any applicable law or otherwise shall be cumulative and concurrent and shall be in addition to every other
right, power, or remedy provided for in this Note or any of the other Loan Documents or now or hereafter existing under any applicable law, and the exercise or beginning of the exercise by the Lender of any one or more of such rights, powers, or
remedies shall not preclude the simultaneous or later exercise by the Lender of any or all such other rights, powers, or remedies. No failure or delay by the Lender to insist upon the strict performance of any term, condition, covenant, or agreement
of this Note or any of the other Loan Documents, or to exercise any right, power, or remedy consequent upon a breach thereof, shall constitute a waiver of any such term, condition, covenant, or agreement or of any such breach, or preclude the Lender
from exercising any such right, power, or remedy at a later time or times. By accepting payment after the due date of any amount payable under the terms of this Note, the Lender shall not be deemed to waive the right either to require prompt payment
when due of all other amounts payable under the terms of this Note or to declare an Event of Default for the failure to effect such prompt payment of any such other amount. No course of dealing or conduct shall be effective to amend, modify, waive,
release, or change any provisions of this Note. This Note may not be changed orally, but only by an agreement in writing signed by the party against whom enforcement of any waiver, change, modification or discharge is sought. 
 13. Partial Invalidity. If any term or provision of this Note or the application thereof to any person or circumstance shall be invalid or
unenforceable to any extent, the remainder of this Note and the application of such term or provision to persons or circumstances other than those as to which it is held invalid or unenforceable, shall not be affected thereby, and each term and
provision of this Note shall be valid and be enforceable to the fullest extent permitted by law. 
 14. Cross-Default. A
default under any note or any other obligation of the Borrower to the Lender shall, at the option of the holder of this Note, be deemed a default under this Note, entitling the holder of this Note (i) to exercise all of its rights and remedies
hereunder, including the right to accelerate payment of all sums due hereunder; and (ii) to exercise all of its rights and remedies provided in the Loan Agreement to be exercised upon the occurrence of an Event of Default (as defined in the
Loan Agreement). In the event that at any time this Note and any note or any other obligation to the Lender are held by different persons, each of such persons shall have all of the rights, privileges and options provided to the holder of this Note
as provided herein and/or in the Loan Agreement. 
 15. Captions. The captions herein set forth are for convenience only and
shall not be deemed to define, limit, or describe the scope or intent of this Note.

 Subject to the terms and conditions set forth in this Agreement, the Parties agree that as of the Effective Time, Sellers
shall sell, assign, transfer, convey, deliver and release to Purchasers free and clear of all Liens and liabilities (except for Permitted Liens and the Assumed Liabilities) and Purchasers shall purchase, accept and assume from Sellers, all of
Sellers’ right, title and interest in and to the Acquired Assets and the Assumed Liabilities. Each of the Parties understands and agrees that Purchasers are not acquiring or assuming and have no interest in or obligation with respect to the
Excluded Assets and the Retained Liabilities. 
 2.2. Purchase Price. 
 2.2.1. Purchasers shall pay to Sellers, as consideration for the assignment to and assumption by Purchasers of the Acquired Assets and the Assumed
Liabilities related thereto, the “Purchase Price,” which shall be calculated as follows: 
 (a) The Net Trade Book Value
calculated as of the Effective Time in accordance with past practice; plus 
 (b) The net book value of all furniture, office equipment and
select software, hardware, telemetry and other communications equipment (the “Tangible Assets“) being acquired as reflected on Sellers’ balance sheet as of the Effective Time calculated in accordance with past practice; plus

 C. An amount equal to the Market Value of the Natural Gas Inventory owned by Sellers as of the

 (ii) Documentation supporting the calculation of the Estimated Purchase Price, including the Electronically Recorded Trade
Book, a schedule listing the Manually Recorded Commodity Transactions, and a schedule setting forth the energy commodity assets and energy commodity liabilities included in Net Trade Book Value, in each case as of the Estimate Date. 
 (b) On the first Business Day following the Effective Time, Purchasers shall remit to Sellers via wire transfer the amount of the Estimated Purchase
Price less any adjustment calculated as set forth on Schedule 2.2.1(d) and, subject to Section 2.7, any Canadian withholding tax, if applicable. In addition, within seven (7) Business Days following the Effective Time, the
Parties will effect the payment, if any, described in Section 5.10.2. 
 (c) On the first Business Day following the Effective
Time, Purchasers shall deliver the Canadian Withholding Tax Escrow Amount to the Canadian Withholding Tax Escrow Agent as provided in Section 2.7. 
 (d) Within ten (10) Business Days following the Effective Time, Sellers shall in good faith provide to Purchasers its calculation of the Purchase Price as of the Effective Time, together with any supporting
documentation. Within ten (10) Business Days following receipt of this Purchase Price calculation and supporting materials, Purchasers shall notify Sellers in writing as to whether it accepts Sellers’ calculation of the Purchase Price or
provide Sellers with a detailed explanation as to why it is disputing Sellers’ calculation of the Purchase Price. Failing delivery of such notice within such ten (10) Business Day period, Purchasers shall be deemed conclusively to have
accepted Sellers’ calculation of the Purchase Price. 
 (e) If Purchasers agree with Sellers’ calculation of the Purchase Price and
if the Purchase Price exceeds the Estimated Purchase Price (less any adjustment calculated as set forth on Schedule 2.2.1(d)), Purchasers shall remit such difference to Sellers within two (2) Business Days of receipt of Purchasers’
acceptance of the Purchase Price calculation plus interest on such amount calculated at the Applicable Rate from the Closing Date until the date of payment. If the Estimated Purchase Price (less any adjustment calculated as set forth on Schedule
2.2.1(d)) exceeds the Purchase Price, then Sellers shall remit such difference to Purchasers within two (2) Business Days of receipt of Purchasers notification of acceptance of the Purchase Price calculation plus interest on such amount
calculated at the Applicable Rate from the Closing Date until the date of payment. 
 (f) If Purchasers disagree with Sellers’
calculation of the Purchase Price as set forth in Section 2.2.2(d), the Parties will promptly enter into good faith discussions to resolve the differences. If such discussions have not resolved the dispute within thirty (30) days
from the date on which the notice of the dispute was given by Purchasers to Sellers as provided in Section 2.2.2(d), the matter shall be submitted to the chief executive officers of each of the Parties for resolution. If such chief
executive officers have not resolved the dispute within fifteen (15) days of the expiration of the prior thirty (30) day period, the Parties will submit the matter for a determination to Ernst & Young, LLP, and if Ernst &
Young, LLP is unwilling or unable to perform, the dispute will be referred to KPMG LLP, and if KPMG LLP is unable or unwilling to perform, to such other firm of nationally recognized independent certified public accounts as may be acceptable to the
Parties (the “Arbitrator“). The Parties shall promptly make available to the Arbitrator such information and persons as may be requested by the Arbitrator for purposes of making its determination and shall otherwise cooperate with
the Arbitrator as fully as reasonably possible. The Arbitrator shall calculate the Purchase Price in the manner as set forth in Section 2.2 and base its decision on the historical method for calculating the Net Trade Book Value and

  

 3 

 Purchase and Sale Agreement 
  

 
the Commodity Valuation Methodology. The determination of the Arbitrator shall be binding upon the Parties, without the right to appeal or review. If the
Purchase Price as determined by the Arbitrator exceeds the Estimated Purchase Price (less any adjustment calculated as set forth on Schedule 2.2.1(d)), Purchasers shall remit such difference to Sellers within two (2) Business Days of
written receipt of the Arbitrator’s decision plus interest on such amount calculated at the Applicable Rate from the Closing Date until the date of payment. If the Estimated Purchase Price (less any adjustment calculated as set forth on
Schedule 2.2.1(d)) exceeds the Purchase Price as determined by the Arbitrator, then Sellers shall remit such difference to Purchasers within two (2) Business Days of written receipt of the Arbitrator’s decision plus interest on such
amount calculated at the Applicable Rate from the Closing Date until the date of payment. Sellers and Purchasers shall each pay one half of the fees and costs of the Arbitrator. 
 (g) Any remittances required under Sections 2.2.2(d)-(f) herein shall be increased or decreased, as the case may be, to properly reflect the
amount of Canadian withholding tax required to be withheld after taking into consideration the amount of such tax withheld pursuant to Section 2.2.2(c). To the extent that additional withholding tax is required, Purchasers shall withhold
such additional amounts as required and remit such amounts in accordance with the provisions of Section 2.7 on the same day as any additional Purchase Price is remitted to Sellers. 
 2.3. Assumption of Liabilities and Obligations. 
 Immediately after the Effective Time, and subject to Section 2.6, Purchasers shall assume and undertake to pay, discharge and perform all of the Assumed Liabilities. Purchasers are not assuming and shall
not be responsible for, either directly or indirectly, any Retained Liabilities, all of which shall remain the responsibility of Sellers. 
 2.4. Interstate Pipeline and Storage Contracts. 
 Section 3.8 of the Seller Disclosure Schedule includes those Assigned
Contracts that are firm transportation contracts with pipelines located in the United States (“U.S. Pipelines“) subject to the jurisdiction of the FERC (“Interstate Pipeline and Storage Contracts“), the transfer of
which to Purchasers will be subject to the FERC’s capacity release rules and related interstate pipeline tariff provisions. Effective as of the Effective Time and subject to the terms of this Agreement as well as applicable rules and
regulations and tariff provisions of the U.S. Pipelines, Sellers hereby agree to permanently release, and Purchasers hereby agree to assume, the Interstate Pipeline and Storage Contracts on a prearranged basis for their full remaining terms at
maximum rate, except for Interstate Pipeline and Storage Contracts that are contracted at a discounted or negotiated rate. If required under any applicable Law or tariff, Sellers shall post for public bid any Interstate Pipeline and Storage
Contracts that it holds that are contracted at a discounted rate at such discounted rate. At least one Purchaser agrees to bid on such contract at the discounted or negotiated rate. Sellers and Purchasers agree to comply with all applicable laws and
all applicable provisions and procedures of the U.S. Pipelines’ tariffs necessary to enable Purchasers to take direct, permanent assignment of the Interstate Pipeline and Storage Contracts. The applicable Purchaser agrees to promptly execute
any revised or amended service agreements tendered to it by any of the U.S. Pipelines, each with a term beginning on the Effective Time and continuing through the remaining term of each respective Interstate Pipeline and Storage Contract. These
revised or amended service agreements will be deemed null and void if this Agreement is terminated pursuant to Section 9, and, if necessary, Purchasers will reassign and Sellers will accept reassignment of the Interstate Pipeline and
Storage Contracts. For the avoidance of doubt, the Jackson Prairie Capacity Release Agreement shall not be considered an Interstate Pipeline and Storage Contract for purposes of this Section. 
 2.5. Canadian Pipeline Agreements. 
 Section 3.8 of the Seller Disclosure Schedule includes those Assigned Contracts that are firm transportation contracts with pipelines located in Canada (“Canadian Pipelines“) and subject to the 

  

 4 

 Purchase and Sale Agreement 
  

 
jurisdiction of the National Energy Board (“Canadian Pipeline Contracts“), the assignment of which to Purchasers will be subject to the
respective tariffs of the Canadian Pipelines and any applicable National Energy Board rules and provincial regulations. Effective as of the Effective Time and subject to the terms of this Agreement, as well as all applicable rules, regulations and
tariff provisions of the Canadian Pipelines, Sellers hereby agree to permanently assign, and Purchasers hereby agree to assume, the Canadian Pipeline Contracts, each for its full remaining term and at the maximum rate, except for Canadian Pipeline
Contracts that are contracted at a discounted or negotiated rate, which Purchasers agree to assume at the applicable discounted or negotiated rate. Sellers and Purchasers agree to comply with all applicable laws and all applicable provisions and
procedures of the Canadian Pipelines’ tariffs necessary to enable Purchasers to take direct, permanent assignment of the Canadian Pipeline Contracts. The applicable Purchaser agrees to promptly execute any revised or amended service agreements
tendered to it by any of the Canadian Pipelines, each with a term beginning on the Effective Time and continuing through the remaining term of each respective Canadian Pipeline Contract. These revised or amended service agreements will be deemed
null and void if this Agreement is terminated pursuant to Section 9, and, if necessary, Purchasers will reassign and Sellers will accept reassignment of the Canadian Pipeline Contracts. 
 2.6. Deemed Assignment of Contracts. 
 To the extent that the assignment hereunder of any of the Assigned Contracts identified in Section 3.8 of the Seller Disclosure Schedule, other than those Assigned Contracts identified on Schedules 2.2.1(d) and 2.10.16,
shall require the consent of any other party (or in the event that any of the same shall be non-assignable), neither this Agreement nor any actions taken hereunder shall constitute an assignment or an agreement to assign if such assignment or
attempted assignment would constitute a breach thereof or result in a loss or diminution thereof. Sellers shall cooperate with Purchasers to establish a reasonable arrangement designed to provide Purchasers with the benefits and burdens of any such
Assigned Contracts, including to the extent not constituting an assignment or attempted assignment that would violate the foregoing sentence, (a) appointing Purchasers to act as Sellers’ agent to perform all of Sellers’ obligations
under such Assigned Contracts and to collect and promptly remit to Purchasers all compensation received by Sellers pursuant to such Assigned Contracts, (b) Purchasers agreeing to advance on behalf of Sellers, but at the expense of and for the
account of Purchasers, amounts due and owing under such Assigned Contracts for obligations pertaining to periods following the Effective Time (including the provision of credit support as may be required by a Counterparty to such Assigned Contracts)
and (c) to enforce, at the written request of, at the expense of and for the account and benefit of Purchasers, any and all rights of Sellers against any other person arising out of the breach or cancellation of such Assigned Contracts by such
other person or otherwise (any and all of which arrangement shall constitute, as between the Parties, a deemed assignment or transfer); provided that from and after the Effective Time, Sellers shall have no liability to Purchasers in the event that
any Assigned Contract requiring consent to assignment hereunder (or which by its terms is non-assignable) is terminated. Purchasers shall reimburse Sellers’ for their reasonable costs and expenses (other than Taxes) associated with such
alternative arrangements. 
 2.7. Canadian Escrow Agent and Canadian Withholding Tax Certificates. 
 2.7.1. Delivery of Canadian Withholding Tax Certificate. Subject to this Section 2.7, Avista Energy will deliver to the CRA, with a

Tax Certificate Limit in an amount that is not less than the Taxable Canadian Property Purchase Price is not delivered to Purchasers at or before Closing, Purchasers will withhold from the Purchase Price otherwise payable at Closing the Canadian
Withholding Tax Escrow Amount, which amount shall be distributed to the Canadian Withholding Tax Escrow Agent in accordance with the following provisions of this Section 2.7.

 2.7.3. Canadian Withholding Tax Payments to CRA. If an amount is withheld under
Section 2.7.2 and Avista Energy has received confirmation from CRA that CRA will issue a Canadian Withholding Tax Certificate to Avista Energy if an amount not exceeding the Canadian Withholding Tax Escrow Amount is received by the
Receiver General of Canada before the Canadian Withholding Tax Remittance Date, which confirmation has been communicated to Purchasers and is, in form and substance, acceptable to Purchasers, acting reasonably, Purchasers shall notify the Canadian
Withholding Tax Escrow Agent of that confirmation, and the Canadian Withholding Tax Escrow Agent will then pay that amount out of the Canadian Withholding Tax Escrow Amount to the Receiver General of Canada solely for purposes of obtaining the
Canadian Withholding Tax Certificate and subject to the condition that any part of that amount not so applied and not returned by the Receiver General of Canada to the Canadian Withholding Tax Escrow Agent shall be applied to Purchasers’
remittance obligation under subsection 116(5) or (5.3), as applicable of the Canada Tax Act. Purchasers, Avista Energy and the Canadian Withholding Tax Escrow Agent shall cooperate to make reasonable efforts to effect an arrangement with CRA to make
the payment described in this Section 2.7.3 and the Canadian Withholding Tax Certificate issuance to occur on a simultaneous basis. 
 2.7.4. Payments to Sellers. If an amount is withheld under Section 2.7.2 and, before the Canadian Withholding Tax Remittance Date, the Canadian Withholding Tax Escrow Agent receives a Canadian Withholding Tax Certificate
in respect of the Purchased Taxable Canadian Property, the Canadian Withholding Tax Escrow Agent will promptly pay to Sellers: (i) the Canadian Withholding Tax Escrow Amount less any part thereof previously paid to the Receiver General of
Canada pursuant to Section 2.7.3 if the Canadian Withholding Tax Certificate is issued pursuant to subsection 116(4) of the Canada Tax Act; or (ii) where Section 2.7.4(i) does not apply, the Canadian Withholding Tax

specified in that Canadian Withholding Tax Certificate as the Canadian Withholding Tax Certificate Limit or proceeds of disposition, multiplied by (B) the percentage specified in subsection 116(5) of the Canada Tax Act, if the Canadian
Withholding Tax Certificate is issued pursuant to subsection 116(2) of the Canada Tax Act or the percentage specified in subsection 116(5.3) of the Canada Tax Act if the Canadian Withholding Tax Certificate is issued pursuant to subsection 116(5.2)
of the Canada Tax Act. 
 2.7.5. Remittances. If Purchasers have withheld the Canadian Withholding Tax Escrow Amount pursuant to
Section 2.7.2 and Sellers do not deliver to Purchasers and the Canadian Withholding Tax Escrow Agent, before the Canadian Withholding Tax Remittance Date, a Canadian Withholding Tax Certificate under subsection 116(2), subsection 116(4),
or subsection 116(5.2), as applicable, of the Canada Tax Act specifying a Canadian Withholding Tax Certificate Limit or proceeds of disposition equal to or greater than the Taxable Canadian Property Purchase Price, the Canadian Withholding Tax
Escrow Agent will remit to the Receiver General of Canada, on the Canadian Withholding Tax Remittance Date, the Canadian Withholding Tax Amount (less any part thereof previously paid to the Receiver General of Canada on account of such amount
pursuant to Section 2.7.3) and the amount so remitted together with any amounts paid pursuant to Section 2.7.3 shall be credited to Purchasers as a Payment on account of the Purchase Price. 
 2.7.6. Interest. Concurrently with the payments pursuant to Sections 2.7.4 or 2.7.5, if applicable, the Canadian Withholding Tax
Escrow Agent will pay to Sellers the interest earned on the Canadian Withholding Tax Escrow Amount while on deposit with the Canadian Withholding Tax Escrow Agent to the date of that payment (less any Tax required to be withheld and remitted).

 2.7.8. Closing Adjustment. If the Taxable Canadian
Property Purchase Price is adjusted pursuant to Section 2.2.2(g), and Purchasers are required to pay to Sellers an additional amount pursuant to Section 2.2.2(g), the foregoing provisions of this Section 2.7 shall
apply to that additional amount and in those circumstances and for the purpose of this Agreement, the term “Canadian Withholding Tax Escrow Amount” shall include the applicable withholding rate for the Purchased Taxable Canadian Property
times that additional amount, and the term “Canadian Withholding Tax Remittance Date” for such additional amount shall mean the 27th day following the end of the calendar month in which Purchasers are required to pay the additional amount pursuant to Section 2.2.2(g).

 Exhibit G 
 Form of Guaranty 

 GUARANTY 
 This Guaranty Agreement (this “Guaranty”) dated effective as of                     , 2007, is
entered into by Avista Capital, Inc. (“Guarantor”), a Washington corporation, in favor of Coral Energy Holding, L.P., a Delaware limited partnership, Coral Energy Resources, L.P., a Delaware limited partnership, Coral Power, L.L.C., a
Delaware limited liability company and Coral Energy Canada Inc., an Alberta corporation (each being a “Coral Entity” and collectively, the “Coral Entities”). 
 Recitals: 
 A. Guarantor desires that the Coral Entities enter into the
contracts and agreements listed on Attachment A hereto with affiliates of Guarantor including Avista Energy, Inc., Avista Energy Canada, Ltd. and Avista Turbine Power, Inc. (each being a “Guaranteed Party” and collectively, the
“Guaranteed Parties”), as such contracts and agreements listed on Attachment A may be amended, supplemented, renewed, or extended, collectively, from time to time, the “Contracts”; and 
 B. The Guaranteed Parties are subsidiaries or affiliates of Guarantor and Guarantor will directly or indirectly benefit from the Contracts to be entered
into between one or more of the Coral Entities and one or more of the Guaranteed Parties; and 
 C. The Guaranteed Parties and the Coral
Entities are parties to an Indemnification Agreement of even date herewith with respect to certain obligations between such parties in respect of the Contracts (the “Indemnification Agreement”). 
 NOW, THEREFORE, in consideration of the Coral Entities entering into the Contracts with Guaranteed Parties, Guarantor hereby covenants and agrees as
follows: 
 1. Guaranty. Subject to the terms and conditions hereof, Guarantor hereby irrevocably and unconditionally guarantees the timely
performance and payment when due of the obligations of Guaranteed Parties (the “Obligations”) to the Coral Entities, as applicable, under the Indemnification Agreement with respect to the Contracts. To the extent that a Guaranteed Party
shall fail to perform or pay any Obligation, Guarantor shall promptly cause the performance or pay to the applicable Coral Entity the amount due in accordance with the terms, conditions and limitations contained in the Indemnification Agreement.
This Guaranty shall constitute a guarantee of payment and not of collection. Guarantor shall also be liable for the reasonable attorneys’ fees and expenses of such Coral Entity’s external counsel incurred in any successful effort to
collect or enforce any of the obligations under this Guaranty. 
 2. Limitations. Guarantor’s performance hereunder shall be limited to
monetary payments arising out of the Obligations (even if such payments are deemed to be damages) and in no event shall Guarantor be subject hereunder to consequential, exemplary, equitable, loss of profits, punitive, or any other damages, except to
the extent specifically provided in the Indemnification Agreement to be due from a Guaranteed Party. Guarantor waives any and all 

 
defenses, rights and benefits Guarantor might assert to avoid or limit liability on Guarantor’s obligations arising from the bankruptcy, insolvency,
dissolution, or liquidation of Guaranteed Party. The aggregate amount of Guarantor’s liability under or in respect of this Guaranty shall in no event exceed Thirty Million Dollars (U.S.$30,000,000), in the aggregate, plus attorney’s fees
and other expenses specified under Section 1 hereto and shall be calculated by including any amounts paid by any Guaranteed Party under the Indemnification Agreement, or collected on any collateral securing Guarantor’s obligations under
this Guaranty, against such Thirty Million Dollar cap on Guarantor’s liability. 
 3. Termination. This Guaranty shall remain in full
force and effect until April 30, 2011. No termination shall affect, release or discharge Guarantor’s liability with respect to any Obligations existing or arising prior to the effective date of termination. 
 4. Nature of Guaranty. The Guarantor’s obligations hereunder with respect to any Obligation shall not be affected by the existence, validity,
enforceability, perfection, release, or impairment of value of any collateral for such Obligations. The Coral Entities shall not be obligated to file any claim relating to the Obligations owing to it in the event that a Guaranteed Party becomes
subject to a bankruptcy, reorganization, or similar proceeding, and the failure of a Coral Entity to so file shall not affect the Guarantor’s obligations hereunder. In the event that any payment to a Coral Entity in respect of any Obligations
is rescinded or must otherwise be returned in the event that a Guaranteed Party becomes subject to a bankruptcy, reorganization, or similar proceeding, Guarantor shall remain liable hereunder in respect to such Obligations as if such payment had not
been made. 
 5. Subrogation. Guarantor waives its right to be subrogated to the rights of the Coral Entities with respect to any Obligations
paid or performed by Guarantor until all Obligations have been fully and indefeasibly paid to the Coral Entities or otherwise terminated, subject to no rescission or right of return, and Guarantor has fully and indefeasibly satisfied all of
Guarantor’s obligations under this Guaranty. 
 6. Waivers. Guarantor hereby waives any circumstance which might constitute a legal or
equitable discharge of a surety or guarantor, including but not limited to (a) notice of acceptance of this Guaranty; (b) presentment and demand concerning the liabilities of Guarantor; (c) notice of any dishonor or default by, or
disputes with, a Guaranteed Party; and (d) any right to require that any action or proceeding be brought against a Guaranteed Party or any other person, or to require that a Coral Entity seek enforcement of any performance against a Guaranteed
Party or any other person, prior to any action against Guarantor under the terms hereof. Guarantor consents to the renewal, compromise, extension, acceleration, or other modification of the terms of a Contract, without in any way releasing or
discharging Guarantor from its obligations hereunder. Except as to applicable statute of limitations, the time for bringing any claim under the terms of the Indemnification Agreement and duration of this Guaranty as provided in Section 3 above,
no delay of a Coral Entity in the exercise of, or failure to exercise, any rights hereunder shall operate as a waiver of such rights, a waiver of any other rights, or a release of Guarantor from any obligations hereunder. 

 7. REPRESENTATIONS. Guarantor is a corporation duly organized and validly existing under the laws of the
State of Washington. The execution, delivery and performance of this Guaranty have been duly authorized by all necessary corporate action on the part of Guarantor. This Guaranty constitutes the legal, valid and binding obligation of Guarantor
enforceable against Guarantor in accordance with its terms (except that enforcement may be limited by bankruptcy, insolvency, reorganization, or similar laws affecting the enforcement of creditors’ rights generally and general principles of
equity, whether considered in a proceeding in equity or at law). 
 8 Notice. Any payment demand, notice, correspondence or other document to
be given hereunder by any party to another (herein collectively called “Notice”) shall be in writing and delivered personally or mailed by certified mail, postage prepaid and return receipt requested, or by facsimile, to the addresses set
forth below. Notice given by personal delivery or mail shall be effective upon actual receipt, or, if receipt is refused or rejected, upon attempted delivery. Notice given by facsimile shall be effective upon actual receipt if received during the
recipient’s normal business hours, or at the beginning of the recipient’s next business day after receipt if not received during the recipient’s normal business hours. All Notices by facsimile shall be confirmed promptly after
transmission in writing by certified mail or personal delivery. Any party may change any address to which Notice is to be given to it by giving Notice as provided above of such change of address. 
 9. Miscellaneous. THIS GUARANTY SHALL BE IN ALL RESPECTS GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK, WITHOUT
REGARD TO PRINCIPLES OF CONFLICTS OF LAWS EXCEPT SECTIONS 5-1401 AND 5-1402 OF THE NEW YORK GENERAL OBLIGATIONS LAW. No term or provision of this Guaranty shall be amended or modified except in a writing signed by Guarantor and each of the Coral
Entities. A party may assign its rights and obligations hereunder only with the prior written consent of the Coral Entities, in the case of Guarantor, and Guarantor, in the case of any of the Coral Entities, and any attempted assignment without such
prior written consent shall be null and void. Subject to the foregoing, this Guaranty shall be binding upon Guarantor, its successors and assigns, and shall inure to the benefit of and be enforceable by the Coral Entities, their successors and
assigns. This Guaranty and the Indemnification Agreement embodies the entire agreement and understanding between Guarantor and the Coral Entities, and supersedes all prior guaranties issued by Guarantor in connection with the Contracts. 

IN WITNESS WHEREOF, Guarantor has executed this Guaranty effective as of the date first herein written.

Indemnification Claim and (ii) the Indemnified Party will not consent to the entry of any judgment or enter into any settlement with respect to the Indemnification Claim without the prior written consent of the Indemnifying Party which consent
will not be unreasonably withheld or delayed. 
 4.5 Failure to Defend. In the event the Indemnifying Party fails to conduct the
defense of an Indemnification Claim that results from a Third-Party Claim or proceeding in accordance with this Agreement, (i) the Indemnified Party may defend against, and consent to the entry of any judgment or enter into any settlement with
respect to, the Third-Party Claim or proceeding giving rise to the Indemnification Claim in any manner it may deem appropriate (and the Indemnified Party need not consult with, or obtain any consent from, any Indemnifying Party in connection with
the same), (ii) the Indemnifying Party will have the obligation to reimburse the Indemnified Party promptly and periodically for the costs of defending against the Indemnification Claim (including reasonable attorneys’ fees and expenses)

attempted to allocate their responsibility and indemnification obligations in respect of the Effective Time. To the extent that any Claims otherwise covered by this Agreement relate to both the period on and prior to the Effective Time and the
period after the Effective Time, the Indemnification Claim resulting therefrom and the indemnification obligations in respect thereof shall be allocated to the Avista Entities in proportion to the period prior to the Effective Time and to the Coral
Entities in proportion to the period after the Effective Time. If the proportion of indemnification obligations cannot be determined between the Parties in good faith, as set forth in this Section 6, such determination shall be submitted to the
trier of such Claim which determination shall be final and binding as to the Parties. 
 7. Limitations on Liability. 
 7.1 Liability Threshold. Except as provided in the following sentence, and subject to Section 7.3 and 7.4, no Party shall be liable

$150,000 aggregate threshold. Notwithstanding the foregoing liability threshold, the Avista Entities’ indemnification obligations for the Title and Authority Representations, Tax Representations and as set forth in Sections 2.2 and

Claims shall terminate and be of no further force or effect if such Indemnification Claims are not made prior to such dates. 
 7.4
Certain Breaches Not Subject to Limitations. Claims for indemnification with respect to (i) fraud or (ii) intentional misrepresentation shall not be subject to any of the limitations set forth in Section 7.1,
Section 7.2, Section 7.3, Section 8 or Section 9. 
 8. Exclusive Remedy. The rights
of the Avista Entities and the Coral Entities to assert Indemnification Claims and to receive indemnification payments pursuant to this Agreement shall be their sole and exclusive right and remedy with respect to any breach by any other party of any
representation, warranty or covenant contained in the Transaction Agreements, except for the rights provided to the Parties to seek injunctions to prevent breaches of the Transaction Agreements or to enforce specifically the Transaction Agreements,
as provided therein, and in all cases subject to the limitations on liability established in this Agreement. 
 9. Consequential Damages
Limitation. Except as provided in the following sentence, in no event shall any Party have any obligation or liability arising under or relating to the Transaction Agreements (or any other agreement, document or certificate delivered in
connection with the transactions contemplated by the Transaction Agreements) or this Agreement for any consequential, punitive, special or indirect loss or damage, including lost profits or lost opportunities, and each Party hereby expressly
releases the other Parties from the same. As between the Parties to this Agreement, Claims for indemnification with respect to Third-Party Claims under this Agreement shall not be subject to the limitations set forth in the previous sentence to the
extent of such Claims by Third-Parties, but the Parties acknowledge and agree that nothing contained in this Agreement is intended to, nor shall be construed to, waive, modify, amend or release any independent waiver of such consequential damages as
may exist with respect to such Third-Party Claims outside of this Agreement or create a right for any person to recover consequential damages. 
 10. Miscellaneous. 
 10.1 Reliance. Each of the Coral Entities and the Avista Entities expressly confirms and agrees
that it has entered into this Agreement and assumes the obligations imposed on it hereby in order to induce the other Parties to enter into the Transaction Agreements, and each of the Coral Entities and each of the Avista Entities acknowledges that
the other Parties are relying upon this Agreement in entering into the Transaction Agreements. 

 10.2 Entire Agreement. This Agreement, the Transaction Agreements (including the documents
referred to therein) and the Guaranty, the Security Agreement and the Escrow Agreement constitutes the entire agreement between the Parties hereto with respect to the subject matter hereof and supersedes any prior understandings, agreements or
representations by or among the Parties, written or oral, to the extent they related in any way to the subject matter of this Agreement and the Transaction Agreements. 
 10.3 Succession and Assignment. This Agreement shall be binding upon and inure to the benefit of the Parties named in this Agreement and their respective successors and permitted assigns. Except as provided in
the next sentence, no party may assign either this Agreement or any of its rights, interests or obligations under this Agreement without the prior written approval of the other Parties. The Coral Entities and the Avista Entities shall be entitled to
assign this Agreement and any and all of their rights and interests under it to any Affiliate without the prior written approval of the other Parties, but such an assignment shall not relieve, discharge or otherwise affect the duties and obligations
of the assigning Party under this Agreement, all of which shall remain in full force and effect.

may be executed in one or more counterparts, each of which shall be deemed an original but all of which together will constitute one and the same instrument. 
 10.5 Headings. The Section headings contained in this Agreement are inserted for convenience only and shall not affect in any way the meaning or interpretation of this Agreement.

this Agreement. The words “includes” and “including” shall not be words of limitation. The Parties intend that each covenant contained in this Agreement shall have independent significance. If any party has breached any covenant
contained in this Agreement in any respect, the fact that there exists another covenant relating to the same subject matter (regardless of the relative levels of specificity) that the party has not breached shall not detract from or mitigate the
fact that the party is in breach of the first covenant.

 Exhibit M 
 Form of Security Agreement 

 SECURITY AGREEMENT 
 This SECURITY AGREEMENT dated as of             , 2007 (this “Security
Agreement”) is given by Avista Capital, Inc., a Washington corporation (“Debtor”), in favor of Coral Energy Holding, L.P., a Delaware limited partnership (“Coral”), for the benefit of Coral, Coral
Energy Resources, L.P., a Delaware limited partnership, Coral Power, L.L.C., a Delaware limited liability company and Coral Energy Canada Inc., an Alberta corporation (collectively, the “Coral Entities”).

 RECITALS 
  

	A.	Pursuant to that certain Guaranty dated             ,     , 2007, Debtor has agreed to
guaranty certain Obligations of its affiliates, Avista Energy, Inc., Avista Energy Canada Ltd. and Avista Turbine Power, Inc. to the Coral Entities (the “Guaranty”). 

  

	B.	Debtor has agreed to grant to Coral for the benefit of the Coral Entities a security interest in certain of its property as provided herein. 

  

	C.	Coral has agreed to act as agent for and on behalf of the Coral Entities for purposes of this Security Agreement. 

 AGREEMENT 
 For and in consideration
of the promises and the agreements contained in this Agreement and for other good and valuable consideration, the receipt and sufficient of which are hereby acknowledged, the parties agree as follows: 
  

	1.	Definitions. Capitalized terms used and not otherwise defined herein shall have the meanings ascribed to them as set forth in Appendix A attached to and made a part of
this Security Agreement. In the absence of such definitions, any other terms used herein (whether or not capitalized) shall have the meaning ascribed to them by the Code to the extent the same are defined in the Code. 

  

	2.	Grant of Security Interest. Debtor hereby grants to Coral for the benefit of the Coral Entities a first priority security interest in the Collateral to secure the Obligations
including, without limitation: 

  

	 	2.1.	the prompt and complete payment of all Obligations; 

  

	 	2.2.	the timely performance and observance by Debtor of all covenants, obligations and conditions contained in the Guaranty; and 

  

	 	2.3.	without limiting the generality of the foregoing and to the fullest extent permitted under applicable law, the payment of all amounts, including without limitation, interest which
constitutes part of the Obligations and would be owed by Debtor to one or more of the Coral Entities under the Guaranty but for the fact that they are unenforceable or not allowable due to the existence of a bankruptcy, reorganization or similar
proceeding involving Debtor 

 and Debtor hereby agrees to deliver the Collateral to the Escrow Agent under the Escrow
Agreement, to be held by the Escrow Agent as the Escrow Fund under the Escrow Agreement, for the benefit of the Coral Entities. Provided, however, that under no circumstances shall the aggregate of all such obligations secured by this Security
Agreement, including the Obligations and any other amounts referred to above, exceed at any time an aggregate value of Twenty-Five Million Dollars ($25,000,000.00). 
  

	3.	 Substitute Collateral. Debtor shall be entitled at any time, and from time to time, to substitute any of the following, in form and substance reasonably
acceptable to Coral, as substitute 

	 	 
collateral for the Collateral: (a) a cash deposit in an amount equal to Twenty-Five Million Dollars ($25,000,000.00); (b) an irrevocable letter of
credit in a face amount equal to Twenty-Five Million Dollars ($25,000,000.00), issued by a U.S. commercial bank or the U.S. branch of a foreign bank, with such bank having a credit rating of at least A- from the Standard & Poor’s
Rating Group (a division of McGraw-Hill, Inc.) or its successor, or a rating of at least A3 from Moody’s Investor Services, Inc. or its successor, or (c) such other form of collateral security as Coral and Debtor may mutually agree upon.
Upon completion of any such substitution of collateral, the substitute collateral shall become the “Collateral” hereunder, and Coral shall release, return, surrender, and otherwise terminate any security interest granted hereunder in, the
property or instruments previous serving as “Collateral” hereunder. 

  

	4.	Authorization to File Financing Statements. Debtor authorizes Coral to file with the Department of Licensing for the State of Washington an initial financing statement and
continuation statements that (a) indicate the Collateral; and (b) provide any other information required by part 5 of Article 9 of the Code or as required by such other jurisdiction for the sufficiency or filing office acceptance of such
financing statement or continuation statement, including whether Debtor is an organization, the type of organization and any organization identification number issued to Debtor. Debtor agrees to furnish any such information to Coral promptly upon
the request. 

  

	5.	Covenants Concerning Debtor’s Legal Status. Debtor covenants with Coral as follows: 

  

	 	5.1.	Without providing at least 30 days prior written notice to Coral, Debtor will not change its name, its place of business or, if more than one, chief executive office, or its mailing
address or organizational identification number if it has one; 

  

	 	5.2.	If Debtor does not have an organizational identification number and later obtains one, Debtor will promptly notify Coral of such organizational identification number; and

  

	 	5.3.	Without providing at least 30 days prior written notice to Coral, Debtor will not change its type of organization, jurisdiction of organization or other legal structure.

  

	6.	Representations and Warranties Concerning Collateral. Debtor further represents and warrants to Coral as follows: 

  

	 	6.1.	Except for the security interests granted to Coral in this Agreement, Debtor owns good and marketable title to the Collateral free and clear of all Liens, and neither the Collateral
nor any interest in the Collateral has been transferred to any other party. Debtor has full right, power and authority to grant a first-priority security interest in the Collateral to Coral in the manner provided in this Security Agreement, free and
clear of any other Liens, adverse claims and options and without the consent of any other person or entity or if consent is required, such consent has been obtained. No other Lien, adverse claim or option has been created by Debtor or is known by
Debtor to exist with respect to any Collateral; and to the best of Debtor’s knowledge and belief no financing statement or other security instrument is on file in any jurisdiction covering such Collateral other than the security interest in
favor of Coral under this Security Agreement. The security interest granted is a first lien security interest. 

  

	 	6.2.	There are no actions, suits or proceedings pending or threatened against or affecting the Collateral before any court or by or before any governmental department, commission, board,
bureau, agency or instrumentality, domestic or foreign, which in any manner draws into question the validity of this Security Agreement. 

  

	7.	Covenants Concerning the Collateral. 

  

	 	7.1.	 Debtor covenants with Coral that while this Security Agreement remains in effect, that except for the security interest herein granted and the deposit of the
Collateral with the Escrow Agent 

	 	 
under the Escrow Agreement, Debtor is and shall be the owner of or have other transferable rights in the Collateral free from any right or claim of any other
person or any Lien, security interest or other encumbrance, and Debtor shall defend the same against all claims and demands of all persons at any time claiming the same or any interest therein adverse to Coral. Debtor shall not pledge, mortgage or
create, or suffer to exist any right of any person in or claim by any person to the Collateral, or any security interest, Lien or other encumbrance in the Collateral in favor of any person other than Coral; nor permit any person, other than Coral,
to file any financing statement or security interest in the Collateral. 

  

	 	7.2.	In the event of (a) a sale, transfer, disposition or reorganization of greater than 50% of the equity of Debtor’s subsidiary, Advantage IQ, Inc, a Washington corporation
(“Advantage”), (b) Debtor ceasing to own and control shares of stock of and other equity interests in Advantage representing a majority of the votes entitled to be cast by shareholders of Advantage and a majority of the equity
value of Advantage, or (c) the sale, transfer or other disposition of the underlying assets of Advantage outside the ordinary course of business, Debtor agrees to replace the Collateral with substitute Collateral as set forth Section 3.

  

	8.	Securities and Deposits. Coral may at any time following and during the continuance of an Event of Default, at its option, transfer to itself or any nominee any securities
constituting Collateral, receive any income thereon and hold such income as additional Collateral or apply it to the Obligations. Whether or not any Obligations are due, Coral may following and during the continuance of an Event of Default demand,
sue for, collect or make any settlement or compromise that it deems desirable with respect to the Collateral. 

  

	9.	Rights and Remedies. If an Event of Default shall have occurred and is continuing, Coral shall have in any jurisdiction in which enforcement hereof is sought, in addition to
all other rights and remedies, the rights and remedies of a secured party under the Code and any additional rights and remedies as may be provided to a secured party in any jurisdiction in which Collateral is located, including, without limitation,
the right to take possession of the Collateral. 

  

	10.	No Waiver by Coral. Coral shall not be deemed to have waived any of its rights and remedies in respect of the Obligations or the Collateral unless such waiver shall be made
in writing and signed by Coral. No delay or omission on the part of Coral in exercising any right or remedy shall operate as a waiver of such right or remedy or any other right or remedy. A waiver on any occasion shall not be construed as a bar to
or a waiver of any right or remedy on any future occasion. All rights and remedies of Coral with respect to the Obligations or the Collateral, whether evidenced hereby or by any other instrument or papers, may be exercised by Coral, shall be
cumulative and may be exercised singularly, alternatively, successively or concurrently at such time or at such times as Coral deems expedient. 

  

	11.	Marshalling. Subject to the terms and conditions of this Security Agreement and the Indemnification Agreement, Coral shall not be required to marshal the Collateral, or other
assurances of payment of the Obligations, or any of them or to resort to the Collateral or other assurance of payment in any particular order, and all of the rights and remedies hereunder and in respect of the Collateral and other assurances of
payment shall be cumulative and in addition to all other rights and remedies, however existing or arising. TO THE EXTENT THAT IT LAWFULLY MAY, DEBTOR HEREBY AGREES THAT IT WILL NOT INVOKE ANY LAW RELATING TO THE MARSHALLING OF COLLATERAL WHICH
MIGHT CAUSE DELAY IN OR IMPEDE THE ENFORCEMENT OF CORAL’S RIGHTS AND REMEDIES UNDER THIS SECURITY AGREEMENT OR UNDER ANY OTHER INSTRUMENT CREATING OR EVIDENCING ANY OF THE OBLIGATIONS OR UNDER WHICH ANY OF THE OBLIGATIONS IS OUTSTANDING OR BY
WHICH ANY OF THE OBLIGATIONS IS SECURED OR PAYMENT THEREOF IS OTHERWISE ASSURED, AND, TO THE EXTENT THAT IT LAWFULLY MAY, DEBTOR HEREBY IRREVOCABLY WAIVES THE BENEFITS OF ALL SUCH LAWS. 

	12.	Overdue Amounts. Until paid, all amounts due and payable by Debtor hereunder shall be a debt secured by the Collateral and shall bear, whether before or after judgment,
interest determined by reference to the U.S. Dollar London Interbank Offer Rate (LIBOR) quoted on Bloomberg page BBAM applicable for the relevant one-month period (or any successor or substitute page of such publication, or any successor to or
substitute for such publication, providing rate quotations comparable to those currently provided on such page or such publication) at approximately 11:00 a.m., London time, two Business Days prior to the commencement of such interest period.

  

	13.	Notices. All communications hereunder shall be in writing and may be delivered by hand delivery, United States mail, overnight courier service or facsimile. Notice by
facsimile or hand delivery shall be effective on the day actually received, if received during business hours on a Business Day, and otherwise shall be effective at the beginning of the recipient’s next Business Day. Notice by overnight United
States mail or courier shall be effective on the next Business Day after it was sent to the appropriate notice address set forth below or at such other address as any party hereto may have furnished to the other party in writing:
