SECTION 2. THE LOANS

2.1 Term Loans.

(a) Advances. Subject to the terms and conditions of this Agreement, (i) on the Closing Date, Lender will make a single Advance in the amount of Eighty-Five Million and No/100 Dollars ($85,000,000.00) and (ii) on the Secondary Closing Date, Lender will make a single Advance in the amount of Fifteen Million and No/100 Dollars ($15,000,000.00); provided that, as a condition to the advance made on the Secondary Closing Date, Borrower shall have paid to Lender the Secondary Closing Date Closing Fee. Borrower shall have no right to reborrow any amount repaid or prepaid with respect to the Initial Term Loan, except as otherwise may be permitted pursuant to Section 2.7(a)(i).

(b) Advance Request. To obtain the Initial Term Loan or any Incremental Term Loan, Lead Borrower shall complete, sign and deliver an Advance Request (at least three (3) Business Days before the Closing Date or Advance Date, as applicable) to Lender. Lender shall fund such Term Loan in the manner requested by the Advance Request; provided that each of the conditions precedent set forth herein, including in Section 4 of this Agreement, and applicable to such Term Loan is satisfied as of the requested Advance Date.

(c) Interest. The outstanding principal balance of each Term Loan shall bear interest thereon from the Advance Date pertaining thereto at the Term Loan Interest Rate. Interest on the outstanding principal balance of each Term Loan shall be calculated daily on the basis of a 360-day year and actual days elapsed. All accrued and unpaid interest on all outstanding Term Loans shall be paid in arrears (i) on the date of, and from the aggregate amount of, any payment made to Lender pursuant to Section 2.1(d)(i), below, and (ii) on the Term Loan Maturity Date. If, as of the last Business Day of any month, accrued and unpaid interest has not been paid in full pursuant to Section 2.1(d)(i), below, such interest then owing shall compound and be capitalized and added to the principal amount of all Term Loans on each such date, until the principal amount of all Term Loans has been repaid or prepaid, and shall be due and payable on the date of repayment or prepayment, as applicable, of the unpaid principal amount of the Term Loans. For the avoidance of doubt, compounding and capitalization of interest as aforesaid shall not constitute a default for purposes of Section 9.1 until such interest shall fail to be paid on the date of such repayment or prepayment, as applicable. Any interest owing after the Term Loan Maturity Date shall be due and payable on demand.

(d) Payments.

(i) At any time that any amount shall be payable to Borrower from a Project Restricted Account, including any cash collateral released therefrom, Borrower shall cause such amount to be paid directly to the Lender at the Lender Account. If, notwithstanding the foregoing, any such amount shall be paid directly to Borrower, Borrower (x) shall receive and hold such amount in trust for the Lender, (y) shall not commingle such amount with any other assets or funds of Borrower, and (z) shall, within three (3) Business Days following such receipt, pay such amount to the Lender at the Lender Account in the form received, with any necessary endorsements. Each such payment described in this Section 2.1(d)(i) shall be applied to the Secured Obligations in order of the following priority: first, to pay any fees, costs or expenses then due and payable to the Lender under the Loan Documents, second, to pay all accrued and unpaid interest on the outstanding principal amount of all Term Loans, and third, to the outstanding principal amount of all Term Loans until the Loans are Paid In Full. Without limiting the foregoing, the then-outstanding principal balance of all Advances, and all accrued but unpaid interest thereunder, and any and all other Secured Obligations under the Loan Documents shall in any event be due and

payable on Term Loan Maturity Date. Borrower shall make all payments under this Agreement without setoff, recoupment or deduction and regardless of any counterclaim or defense except as otherwise required by law.

(ii) If, as of any Balance Test Date, the payments paid on or prior to such Balance Test Date directly to the Lender pursuant to Section 2.1(d)(i) above are insufficient to pay any fees, costs or expenses then due and payable on or prior to such Balance Test Date, then Borrower shall have the right to pay in cash any amounts owing under clauses (x) and (y) above within five (5) Business Days after such Balance Test Date.

(iii) If, as of any Balance Test Date, the outstanding principal balance of all Term Loans (including any and all interest, if any, that has been compounded, capitalized and added to such principal balance as set forth in Section 2.1(c), above) is not equal to or less than the amount set forth opposite such Balance Test Date on the Amortization Schedule, then Borrower shall have the right to pay in cash any such deficiency within one (1) Business Day after such Balance Test Date.

(e) Resizing of Loans; Amortization Schedule. Borrower and Lender agree that the Amortization Schedule in existence on the Closing Date has been prepared in reliance on Escrow Release Amounts projected to be released and utilized to repay the Loans in accordance with Section 2.1(d) through the fiscal year ending December 31, 2019. As of January 1, 2020, the Amortization Schedule shall be deemed to be automatically amended, such that the Amortization Schedule incorporates the actual Escrow Release Amounts released and utilized to repay the Loans during the fiscal year ending December 31, 2019, and which amended Amortization Schedule will (i) be prepared using the loan resizing formula set forth in Schedule 2.1(e) and (ii) be calculated assuming that Borrower will make a payment of Eight Million and No/100 Dollars ($8,000,000.00) to Lender on the Term Loan Maturity Date. Within fifteen (15) Business Days of December 31, 2019, Borrower shall be required to prepay the Term Loans in an aggregate amount equal to the lesser of (x) Fifteen Million and No/100 Dollars ($15,000,000.00) and (y) the difference between (1) the amount set forth under the heading “Max Outstanding Balance” opposite the Balance Test Date of December 31, 2019 on the Amortization Schedule in effect as of the Closing Date and (2) the amount set forth under the heading “Max Outstanding Balance” opposite the Balance Test Date of December 31, 2019 on the amended Amortization Schedule. Lender agrees to deliver to Borrower an updated Amortization Schedule, which has been amended in accordance with this Section 2.1(e), as soon as reasonably practicable after December 31, 2019.

2.2 Maximum Interest. Notwithstanding any provision in this Agreement or any other Loan Document, it is the parties’ intent not to contract for, charge or receive interest at a rate that is greater than the maximum rate permissible by law that a court of competent jurisdiction shall deem applicable hereto (which under the laws of the State of New York shall be deemed to be the laws relating to permissible rates of interest on commercial loans) (the “Maximum Rate”). If a court of competent jurisdiction shall finally determine that Borrower has actually paid to Lender an amount of interest in excess of the amount that would have been payable if all of the Secured Obligations had at all times borne interest at the Maximum Rate, then such excess interest actually paid by Borrower shall be applied as follows: first, to the payment of the Secured Obligations consisting of the outstanding principal; second, after all principal is repaid, to the payment of Lender’s accrued interest, reasonable and documented out-of-pocket costs, expenses, professional fees and any other Secured Obligations; and third, after all Secured Obligations are repaid, the excess (if any) shall be refunded to Borrower.

2.3 Default Interest. Upon the occurrence and during the continuation of an Event of Default

hereunder, all outstanding Secured Obligations, including principal, interest, compounded interest, fees and other amounts owing hereunder shall, to the extent permitted by applicable law, bear interest at the Default Rate, with such Default Rate to be effective on the first date as of which the applicable Event of Default occurs notwithstanding the fact that such Event of Default may not be reported or otherwise discovered until a subsequent date.

2.4 Prepayment.

(a) Borrower shall not be permitted to prepay any portion of the outstanding Term Loans prior to August 1, 2019.

(b) At any time on or after August 1, 2019, at its option upon at least one (1) Business Day prior written notice to Lender from Lead Borrower, Borrower may prepay in whole or in part the outstanding Term Loans by paying the entire outstanding principal balance (or a portion thereof) and all accrued and unpaid interest thereon, and, if applicable, a prepayment charge equal to (i) if such prepayment occurs at any time during the period beginning on August 1, 2019 through and including January 31, 2020, ten percent (10.0%) of the amount of Term Loans being prepaid, (ii) if such prepayment occurs at any time during the period beginning on February 1, 2020 through and including January 31, 2021, five percent (5.0%) of the amount of Term Loans being prepaid, and (iii) if such prepayment occurs at any time on or after February 1, 2021, one percent (1.0%) of the amount of Term Loans being prepaid (any such charge specified in clause (i), (ii) or (iii) above, a “Prepayment Charge”). Borrower shall not be obligated to pay a Prepayment Charge (and no Prepayment Charge will be due) with respect to (x) any Term Loan that is repaid with amounts released from a Project Restricted Account or (y) any prepayment required pursuant to Section 2.1(e) or permitted pursuant to Section 7.22. Borrower agrees that the Prepayment Charge is a reasonable calculation of Lender’s lost profits in view of the difficulties and impracticality of determining actual damages resulting from an early repayment of the Advances. Notwithstanding the foregoing, Lender agrees to waive the Prepayment Charge if Lender (in its sole, absolute and unfettered discretion) agrees in writing to refinance the Term Loans prior to the Term Loan Maturity Date.

2.5 Notes. The Loans made by Lender shall be evidenced by one or more accounts or records maintained by Lender in the ordinary course of business. The accounts and records maintained by Lender shall be conclusive absent manifest error of the amounts of the Loans made by Lender to Borrower and the interest and payments thereon. Borrower shall execute and deliver to Lender (and/or, if applicable and so specified in such notice, to any Person who is an assignee of Lender pursuant to Section 11.12 promptly after Borrower’s receipt of such notice) a Note or Notes to evidence Lender’s Loans.

2.6 Taxes.

(a) Payments Free of Taxes. Any and all payments by or on account of any obligation of the Borrower under any Loan Document shall be made without deduction or withholding for any Taxes, except as required by applicable law. If any applicable law (as determined in the good faith discretion of an applicable Withholding Agent) requires the deduction or withholding of any Tax from any such payment by a Withholding Agent, then the applicable Withholding Agent shall be entitled to make such deduction or withholding and shall timely pay the full amount deducted or withheld to the relevant Governmental Authority in accordance with applicable law and, if such Tax is an Indemnified Tax, then the sum payable by the Borrower shall be increased as necessary so that after such deduction or withholding has been made (including such deductions and withholdings applicable to additional sums

payable under this Section) the Lender receives an amount equal to the sum it would have received had no such deduction or withholding been made.

(b) Payment of Other Taxes by the Borrower. The Borrower shall timely pay to the relevant Governmental Authority in accordance with applicable law, or at the option of the Lender timely reimburse it for the payment of, any Other Taxes.

(c) Indemnification by the Borrower. The Borrower shall indemnify the Lender within ten (10) days after demand therefor, for the full amount of any Indemnified Taxes (including Indemnified Taxes imposed or asserted on or attributable to amounts payable under this Section) payable or paid by the Lender or required to be withheld or deducted from a payment to the Lender, and any reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to the Borrower by the Lender shall be conclusive absent manifest error.

(d) Evidence of Payments. As soon as practicable after any payment of Taxes by the Borrower to a Governmental Authority pursuant to this Section 2.6, the Lead Borrower shall deliver to the Lender the original or a certified copy of a receipt issued by such Governmental Authority evidencing such payment, a copy of the return reporting such payment or other evidence of such payment reasonably satisfactory to the Lender.

(e) Status of Lender.

(i) Upon Lead Borrower’s request, Lender shall deliver to Lead Borrower such properly completed and executed documentation reasonably requested by Lead Borrower as will permit payments to be made under the Loan Documents without withholding or at a reduced rate of withholding. In addition, Lender, if reasonably requested by Lead Borrower, shall deliver such other documentation prescribed by applicable law or reasonably requested by Lead Borrower as will enable Lead Borrower to determine whether or not Lender is subject to backup withholding or information reporting requirements. Notwithstanding anything to the contrary in the preceding two sentences, the completion, execution and submission of such documentation (other than such documentation set forth in Section 2.6(e) below) shall not be required if in the Lender’s reasonable judgment such completion, execution or submission would subject the Lender to any material unreimbursed cost or expense or would materially prejudice the legal or commercial position of the Lender.

(ii) Without limiting the generality of the foregoing, the Lender shall deliver to Lead Borrower on or prior to the date on which the Lender makes the Term Loan Advance under this Agreement (and from time to time thereafter upon the reasonable request of Borrower or Lender), executed copies of IRS Form W-9 certifying that the Lender is exempt from U.S. federal backup withholding tax.

(f) Treatment of Certain Refunds. If any party determines, in its sole discretion exercised in good faith, that it has received a refund of any Taxes as to which it has been indemnified pursuant to this Section 2.6 (including by the payment of additional amounts pursuant to this Section 2.6), it shall pay to the indemnifying party an amount equal to such refund (but only to the extent of indemnity payments made under this Section 2.6 with respect to the Taxes giving rise to such refund), net of all out-of-pocket expenses (including Taxes) of such indemnified party and without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund). Such indemnifying party, upon the request of such indemnified party, shall repay to such indemnified party the amount paid over pursuant to

this paragraph (f) (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) in the event that such indemnified party is required to repay such refund to such Governmental Authority. Notwithstanding anything to the contrary in this paragraph (f), in no event will the indemnified party be required to pay any amount to an indemnifying party pursuant to this paragraph (f) the payment of which would place the indemnified party in a less favorable net after-Tax position than the indemnified party would have been in if the Tax subject to indemnification and giving rise to such refund had not been deducted, withheld or otherwise imposed and the indemnification payments or additional amounts with respect to such Tax had never been paid. This paragraph shall not be construed to require any indemnified party to make available its Tax returns (or any other information relating to its Taxes that it deems confidential) to the indemnifying party or any other Person.

(g) Survival. Each party’s obligations under this Section 2.6 shall survive the repayment, satisfaction or discharge of all obligations under any Loan Document.

2.7 Incremental Term Loans.

(a) From time to time after the Closing Date and in accordance with this Section 2.7, Borrower and Lender may enter into an agreement to increase the aggregate amount of the Loans (each such increase, an “Incremental Term Loan Commitment”) and, subject to such Incremental Term Loan Commitment, Borrower may borrow additional Term Loans (each, an “Incremental Term Loan”) so long as the following conditions are satisfied:

(i) the aggregate outstanding principal amount of all Term Loan Advances, including all Incremental Term Loan Commitments made or requested to be made, and after giving effect to any repayment or prepayment of any Term Loans hereunder, shall not, at any time, exceed One Hundred Million and No/100 Dollars ($100,000,000.00) or such greater amount as Lender may determine in its sole and absolute discretion;

Lender shall notify Lead Borrower in writing about whether it will offer an Incremental Term Loan Commitment and the amount of such Incremental Term Loan Commitment within five (5) Business Days of its receipt of Lead Borrower’s request.

(c) Subject to subsections (a) and (b) above, any Incremental Term Loan Commitment requested by Lead Borrower shall be effective upon delivery to Lender of each of the following documents:

(d) Notwithstanding anything contained herein to the contrary, neither Borrower nor Lender shall be obligated at any time to enter into any agreement to provide Incremental Term Loans or Incremental Term Loan Commitments, and any obligation of Lender to make Incremental Term Loans pursuant to any Incremental Term Loan Commitment shall be subject to the terms and conditions set forth herein, including, without limitation, the conditions set forth in Section 4 hereof.

2.8 Deployment Commitment. If, on the earlier of (a) the date Borrower has prepaid in full all Secured Obligations and (b) December 31, 2021 (the “Specified Date”), Borrower has failed to procure, for the purpose of financing additional projects, from Generate Lending, LLC, or an affiliate thereof, structured project financing in an aggregate amount of at least Fifty Million and No/100 Dollars ($50,000,000.00), which financing shall not include any Term Loans made pursuant to this Agreement, Borrower will, within five (5) Business Days of the Specified Date, pay Lender a deployment fee equal to (i)(x) the aggregate amount of all structured project financing procured by Borrower from Generate Lending, LLC or an affiliate thereof (not including any Term Loans made pursuant to this Agreement) to finance such additional projects, divided by (y) $50,000,000.00, multiplied by (ii) One Million, Five Hundred Thousand and No/100 Dollars ($1,500,000.00); provided, that, for a Specified Date occurring pursuant to clause (a) above, such payment shall be made directly to Lender at an account specified by Lender, and such payment shall be held in escrow by Lender until December 31, 2021, at which time the deployment fee shall be recalculated based on the amount of all structured project financing procured by Borrower from Generate Lending, LLC or an affiliate thereof (not including any Term Loans made pursuant to this Agreement) as of such date, and any excess shall be refunded to Borrower; provided, further, that, for a Specified Date occurring pursuant to clause (b) above, such payment shall be made directly to the Lender Account and shall not be subject to any refund or reimbursement. For example, if, as of the Specified Date, Borrower has procured Twenty-Five Million Dollars ($25,000,000) from Generate Lending, LLC to finance additional projects, the deployment fee would be Seven Hundred Fifty Thousand and No/100 Dollars ($750,000.00) (($25,000,000.00 divided by $50,000,000.00) times $1,500,000.00). For the avoidance of doubt, nothing in this Section 2.8 shall represent a commitment on behalf of Generate Lending, LLC or any of its affiliates to provide any loans or other financing outside the scope of this Agreement and does not create any obligations or liability on the part of Generate

Lending, LLC or any of its affiliates in connection therewith. This Section 2.8 shall survive the repayment of indebtedness under, and otherwise shall survive the expiration or other termination of, this Agreement.

SECTION 3. SECURITY INTEREST

3.1 As security for the prompt and complete payment when due (whether on the Payment Dates, Balance Test Dates or otherwise) of all the Secured Obligations, Borrower grants to Lender a security interest in all of Borrower’s right, title, and interest in and to the following personal property, in each case, whether now owned or existing or hereafter acquired or arising (collectively, the “Collateral”): (a) Receivables; (b) Equipment; (c) Fixtures; (d) General Intangibles; (e) Inventory; (f) Investment Property; (g) Deposit Accounts; (h) Cash; (i) Goods; (j) furniture; (k) Commercial Tort Claims; and (l) Intellectual Property, in each case, wherever located, and including any of Borrower’s property in the possession or under the control of Lender; and, to the extent not otherwise included, all Proceeds of each of the foregoing and all accessions to, substitutions and replacements for, and rents, profits and products of each of the foregoing.

3.2 Notwithstanding the broad grant of the security interest set forth in Section 3.1, above, nor anything else in any of the Loan Documents, the Collateral shall not include: (a) more than 65% of the presently existing and hereafter arising issued and outstanding shares of capital stock of any Foreign Subsidiary (or of any holding company, substantially all the assets of which consist directly or indirectly of equity interests or debt issued by one or more Foreign Subsidiaries) which shares entitle the holder thereof to vote for directors or any other matter; (b) any “intent to use” trademarks at all times prior to the first use thereof, whether by the actual use thereof in commerce, the recording of a statement of use with the United States Patent and Trademark Office or otherwise; (c) any permits, state or local franchises, charters, authorizations or licenses issued to any Borrower as the holder or licensee thereof, or any Project Financing Document to which any Borrower or any SPE is party, or any other contracts or other agreements to which any Borrower or any SPE is a party (including, without limitation, those agreements set forth on Schedule 3.2) and any Project, equipment or other property subject thereto (including, without limitation, leased or pledged thereunder), now existing or entered into in the future, in each case only (x) to the extent and for so long as the terms of such permit, franchise, charter, authorization, license, lease, contract or other agreement effectively (after giving effect to Sections 9-406 through 9-409, inclusive, of the UCC in the applicable state (or any successor provision or provisions) or any other applicable laws) prohibits the creation by such Borrower of a security interest in such permit, license, lease, contract or other agreement or any Project, equipment or other property subject thereto in favor of the Lender or would result in an effective invalidation, termination, default or breach of the terms of any such permit, license, lease, contract or other agreement (after giving effect to Sections 9-406 through 9-409, inclusive, of the UCC in the applicable state (or any successor provision or provisions) or any other applicable laws) in each case unless and until any required consents are obtained and (y) solely to the extent of the underlying obligations secured thereby, provided that if and when the prohibition which prevents the granting of a Lien is removed, terminated or otherwise becomes unenforceable as a matter of law (including, without limitation, the termination of any such security interest resulting from the satisfaction of the obligations secured thereby), and notwithstanding any previous release of Lien provided by the Lender requested in connection with respect to any such obligations, the Collateral will be deemed to include, and at all times to have included, such permits, state or local franchises, charters, authorizations, licenses, leases, contracts or other agreements and any Project, equipment or other property subject thereto, in each case without further action or notice by any Person; (d) any capital stock or other equity interest of any SPE; (e) any equipment securing purchase money indebtedness or Indebtedness relating to capital leases if the granting of a Lien to any third party is prohibited by the agreement(s) setting forth the terms and conditions applicable to such Indebtedness, but only if such Indebtedness and the Liens securing the same are permitted by this Agreement, provided

that if and when the prohibition which prevents the granting of a Lien in any such equipment is removed, terminated or otherwise becomes unenforceable as a matter of law (including, without limitation, the termination of any such security interest resulting from the satisfaction of the Indebtedness secured thereby), and notwithstanding any previous release of Lien provided by the Lender requested in connection with respect to any such Indebtedness, the Collateral will be deemed to include, and at all times shall have included, such equipment without further action or notice by any Person; and (f) any Deposit Accounts that constitute Project Restricted Accounts, but only so long as such Project Restricted Accounts are prohibited from being pledged to the Lender pursuant to the applicable Project Financing Documents.

3.3 Lender agrees that the security interest granted in Section 3.1 shall continue until the Secured Obligations (other than contingent indemnification or reimbursement obligations that are not yet due and payable) have been paid in full and Lender has no further commitment or obligation hereunder or under the other Loan Documents to make any further Advances, at which time Lender shall promptly terminate the security interest and, at Borrower’s expense, take all actions reasonably requested by Borrower to evidence such termination, including the prompt return of any possessory collateral held by Lender.

5.6 Laws.

(a) Borrower is not in violation of any law, rule or regulation (including Environmental Laws), or in default with respect to any judgment, writ, injunction or decree of any governmental authority, where such violation or default is reasonably expected to result in a Material Adverse Effect. No

In addition, to the knowledge of Borrower with respect to any Person other than Borrower or its Subsidiaries, no event of default or event that with the passage of time would result in an event of default exists under any provision of the Project Documents or any other agreement or instrument evidencing material Indebtedness, or any other material agreement to which it is a party or by which it is bound that default is reasonably be expected to result in a Material Adverse Effect. Borrower, its Affiliates and, to the knowledge of the Borrower and its Affiliates, any agent or other party acting on behalf of Borrower or its Affiliates are in compliance with all applicable anti-money laundering, economic sanctions and anti-bribery laws and regulations, and none of the funds to be provided under this Agreement will be used, directly or indirectly, for any activities in violation of such laws and regulations.

(b) There are no past or present events, conditions, circumstances, activities, practices, incidents, actions or plans which could reasonably be expected to interfere with or prevent continued material compliance, or which could reasonably be expected to give rise to any common law or statutory liability, under, relating to or in connection with any Environmental Law, or otherwise form the basis of any material claim, action, suit, proceeding, hearing or investigation under applicable law based on or related to the manufacture, processing, distribution, use, treatment, storage, transport or handling, or the release or threatened release into the environment, of any Hazardous Material with respect to any Borrower or their respective Subsidiaries, or any of their respective businesses, in each case that could reasonably be expected to have a Material Adverse Effect.

(c) Borrower and its Subsidiaries (i) are in compliance with any and all applicable Environmental Laws, (ii) have received all permits, licenses or other approvals required of them under applicable Environmental Laws to conduct their respective businesses and (iii) are in compliance with all terms and conditions of any such permit, license or approval, except in each case where noncompliance with Environmental Laws, failure to receive required permits, licenses or other approvals or failure to comply with the terms and conditions of such permits, licenses or approvals would not, singly or in the aggregate, have a Material Adverse Effect on Borrower and its Subsidiaries, taken as a whole. Borrower and its Subsidiaries are not aware of any existing liabilities concerning hazardous or toxic substances or wastes, pollutants or contaminants, that could reasonably be expected to have a Material Adverse Effect on the capital expenditures, earnings or competitive position of Borrower and its Subsidiaries. To the knowledge of Borrower, no property which is or has been owned, leased, used, operated or occupied by Borrower or its Subsidiaries has been designated as a “superfund site” pursuant to the Comprehensive Environmental Response, Compensation of Liability Act of 1980, as amended (42 U.S.C. Section 9601, et. seq.), or otherwise designated as a contaminated sit under applicable state or local law. There are no costs or liabilities associated with Environmental Laws (including, without limitation, any capital or operating expenditures required for clean-up, closure of properties or compliance with Environmental Laws or any permit, license or approval, any related constraints on operating activities and any potential liabilities to third parties) which would, singly or in the aggregate, have a Material Adverse Effect on Borrower and its Subsidiaries, taken as a whole.

No information, report, Advance Request, financial statement, certificate, exhibit or schedule furnished, by or on behalf of Borrower to Lender in connection with any Loan Document or included therein or delivered pursuant thereto contained, or, when taken as a whole, contains or will contain any material misstatement of fact or, when taken together with all other such information or documents, omitted, omits or will omit to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were, are or will be made, not materially misleading at the time such statement was made or deemed made. Additionally, any and all financial or business projections provided by Borrower to Lender, whether prior to or after the Closing Date, shall be (i) provided in good faith and based on the most current data and information available to

Borrower, and (ii) the most current of such projections provided to Borrower’s Board of Directors (it being understood that such projections are subject to significant uncertainties and contingencies, many of which are beyond the control of Borrower, that no assurance is given that any particular projections will be realized and that actual results may differ materially).

5.9 Intellectual Property.

(a) Borrower is the sole owner of, or otherwise has the right to use, the Intellectual Property material to Borrower’s business. Except as described on Schedule 5.9(a), (i) each of the material Copyrights, Trademarks and Patents is valid and enforceable, (ii) no material part of the Intellectual Property has been judged invalid or unenforceable, in whole or in part, and (iii) no claim has been made in writing to Borrower that any material part of the Intellectual Property violates the rights of any third party. Exhibit D is a true, correct and complete list of each of Borrower’s Patents, registered Trademarks, registered Copyrights, and material agreements under which Borrower licenses Intellectual Property from third parties (other than shrink-wrap software licenses), together with application or registration numbers, as applicable, owned by Borrower or any Subsidiary, in each case as of the Closing Date. Borrower is not in material breach of, nor has Borrower failed to perform any material obligations under, any of the foregoing contracts, licenses or agreements and, to Borrower’s knowledge, no third party to any such contract, license or agreement is in breach thereof or has failed to perform any obligations thereunder, except as would not reasonably be expected to result in a Material Adverse Effect.

(b) Except as described on Schedule 5.9(b), Borrower has all material rights with respect to Intellectual Property necessary or material in the operation or conduct of Borrower’s business as currently conducted and proposed to be conducted by Borrower. Without limiting the generality of the foregoing, and in the case of Licenses, except for restrictions that are unenforceable under Article 9 of the UCC, Borrower has the right, to the extent required to operate Borrower’s business, to freely transfer, license or assign Intellectual Property necessary or material in the operation or conduct of Borrower’s business as currently conducted and proposed to be conducted by Borrower, without condition, restriction or payment of any kind (other than license payments in the ordinary course of business) to any third party, and Borrower owns or has the right to use, pursuant to valid licenses, all software development tools, library functions, compilers and all other third-party software and other items that are material to Borrower’s business and used in the design, development, promotion, sale, license, manufacture, import, export, use or distribution of Borrower Products except customary covenants in inbound license agreements and equipment leases where Borrower is the licensee or lessee.

5.10 Litigation. Except as described on Schedule 5.10, (a) there are no actions, suits, proceedings or investigations pending or, so far as the officers of Lead Borrower, or any of them, know, threatened (in writing) before any court or administrative agency naming any Borrower or any Subsidiary of any Borrower as a party or target that, and (b) no Intellectual Property owned by Borrower nor any Borrower Product has been or is subject to any actual or, to the knowledge of Borrower, threatened in writing litigation, proceeding (including any proceeding in the United States Patent and Trademark Office or any corresponding foreign office or agency) or outstanding decree, order, judgment, settlement

agreement or stipulation that restricts in any manner Borrower’s use, transfer or licensing thereof or that may affect the validity, use or enforceability thereof, in either case, that, if adversely determined, could reasonably be expected, in any particular case or in the aggregate, to have a Material Adverse Effect. There is no decree, order, judgment, agreement, stipulation, arbitral award or other provision entered into in connection with any litigation or proceeding that obligates Borrower to grant licenses or ownership interest in any future Intellectual Property related to the operation or conduct of the business of Borrower or Borrower Products. Borrower has not received any written notice or claim, or, to the knowledge of Borrower, oral notice or claim, challenging or questioning Borrower’s ownership in any Intellectual Property (or written notice of any claim challenging or questioning the ownership in any licensed Intellectual Property of the owner thereof) or suggesting that any third party has any claim of legal or beneficial ownership with respect thereto nor, to Borrower’s knowledge, is there a reasonable basis for any such claim. Neither Borrower’s use of its Intellectual Property nor the production and sale of Borrower Products (in each case, other than the Supporting IP) infringes the Intellectual Property or other rights of others. Neither Borrower’s nor ServiceCo’s use of the Supporting IP infringes the Intellectual Property or rights of others.

Borrower does not own any stock, partnership interest or other securities of any Person, except as set forth on Schedule 5.13B. Attached as Schedule 1, as may be updated by Lead Borrower in a written notice provided after the Closing Date, is a true, correct and complete list of each Subsidiary.

5.14 Investment Company Act; Public Utility Holding Company Act; Federal Power Act.

None of Borrower or any of its Subsidiaries is (i) a “holding company” or a “subsidiary company” of a “holding company,” as such terms are defined in the Public Utility Holding Company Act of 1935, as amended, (ii) a “public utility,” as such term is defined in the Federal Power Act, as amended, or (iii) subject to regulation as a “retail electricity supplier,” an “electric supplier” or a “public utility” under the laws of any state or jurisdiction.

The proceeds of any sale, disposition or other realization upon all or any part of the Collateral shall be applied by Lender in the following order of priorities:

First, to Lender in an amount sufficient to pay in full Lender’s reasonable documented costs and professionals’ and advisors’ fees and expenses as described in Section 11.11;

Second, to Lender in an amount equal to the then unpaid amount of the Secured Obligations (including principal, interest, and the Default Rate interest), in such order and priority as Lender may choose in its sole discretion; and

Finally, after the full and final payment in Cash of all of the Secured Obligations (other than inchoate obligations), to Borrower or its representatives or as a court of competent jurisdiction may direct.

Lender shall be deemed to have acted reasonably in the custody, preservation and disposition of any of the Collateral if it complies with the obligations of a secured party under the UCC.

10.3 No Waiver. Lender shall be under no obligation to marshal any of the Collateral for the benefit of Borrower or any other Person, and Borrower expressly waives all rights, if any, to require Lender to marshal any Collateral.

10.4 Cumulative Remedies. The rights, powers and remedies of Lender hereunder shall be in addition to all rights, powers and remedies given by statute or rule of law and are cumulative. The exercise of any one or more of the rights, powers and remedies provided herein shall not be construed as a waiver of or election of remedies with respect to any other rights, powers and remedies of Lender.

11.3 Entire Agreement; Amendments.

(a) This Agreement and the other Loan Documents constitute the entire agreement and understanding of the parties hereto in respect of the subject matter hereof and thereof and supersede and replace in their entirety any prior proposals, term sheets, non-disclosure or confidentiality agreements, letters, negotiations or other documents or agreements, whether written or oral, with respect to the subject matter hereof or thereof.

(b) No amendment, modification, consent or waiver of any provision of this Agreement (including any Exhibit or Schedule hereto (except as otherwise set forth in Section 2.1(e))) or any other Loan Document, and no consent to any departure by either party therefrom, shall be effective unless the

same shall be in writing and signed by an officer of both parties, and then shall be effective only in the specific instance and for the specific purpose for which given.

11.4 No Strict Construction. The parties hereto have participated jointly in the negotiation and drafting of this Agreement. In the event an ambiguity or question of intent or interpretation arises, this Agreement shall be construed as if drafted jointly by the parties hereto and no presumption or burden of proof shall arise favoring or disfavoring any party by virtue of the authorship of any provisions of this Agreement.

11.5 No Waiver. The powers conferred upon Lender by this Agreement are solely to protect its rights hereunder and under the other Loan Documents and its interest in the Collateral and shall not impose any duty upon Lender to exercise any such powers. No omission or delay by Lender at any time to enforce any right or remedy reserved to it, or to require performance of any of the terms, covenants or provisions hereof by Borrower at any time designated, shall be a waiver of any such right or remedy to which Lender is entitled, nor shall it in any way affect the right of Lender to enforce such provisions thereafter.

11.6 Survival. All agreements, representations and warranties contained in this Agreement and the other Loan Documents or in any document delivered pursuant hereto or thereto shall be for the benefit of Lender and shall survive the execution and delivery of this Agreement. Sections 2.8, 6.3 and 11.10 shall survive the termination of this Agreement.

11.7 Successors and Assigns. The provisions of this Agreement and the other Loan Documents shall inure to the benefit of and be binding on Borrower and its permitted assigns (if any). Borrower shall not assign its obligations under this Agreement or any of the other Loan Documents without Lender’s express prior written consent, and any such attempted assignment shall be void and of no effect. Lender may assign, transfer, or endorse its rights hereunder and under the other Loan Documents without prior notice to Borrower, and all of such rights shall inure to the benefit Lender’s successors and assigns; provided that as long as no Event of Default has occurred and is continuing, Lender may not assign, transfer or endorse its rights hereunder or under the Loan Documents to any party that is a Designated Competitor of Borrower, it being acknowledged that in all cases, any transfer to an Affiliate of Lender shall be allowed.

11.8 Governing Law. This Agreement and the other Loan Documents, and any claims, controversy, dispute or cause of action (whether in contract, tort or otherwise) based upon, arising out of or relating to this Agreement or any other Loan Documents (except, as to any other Loan Document, as expressly set forth therein) and the transactions contemplated hereby and thereby shall be governed by, and construed in accordance with the laws of the State of New York (including Section 5-1401 and Section 5-1402 of the General Obligations Law of the State of New York), without regard to any rule of conflicts of law that would result in the application of the substantive law of any jurisdiction other than the State of New York. Nothing in this Agreement shall require any unlawful action or inaction by either party.

11.9 Consent to Jurisdiction and Venue. EACH PARTY HERETO HEREBY IRREVOCABLY AND UNCONDITIONALLY:

(a) (i) SUBMITS FOR ITSELF AND ITS PROPERTY IN ANY LEGAL ACTION OR PROCEEDING RELATING TO THIS AGREEMENT, THE NOTE AND THE OTHER LOAN DOCUMENTS, OR FOR RECOGNITION AND ENFORCEMENT OF ANY JUDGMENT IN RESPECT THEREOF, TO THE EXCLUSIVE GENERAL JURISDICTION OF ANY COURT OF THE STATE OF NEW YORK SITTING IN NEW YORK COUNTY AND OF THE

UNITED STATES DISTRICT COURT OF THE SOUTHERN DISTRICT OF NEW YORK, AND ANY APPELLATE COURT FROM ANY THEREOF;

(ii) CONSENTS THAT ANY SUCH ACTION OR PROCEEDING MAY BE BROUGHT IN SUCH COURTS AND, TO THE EXTENT PERMITTED BY LAW, WAIVES ANY OBJECTION THAT IT MAY NOW OR HEREAFTER HAVE TO THE VENUE OF ANY SUCH ACTION OR PROCEEDING IN ANY SUCH COURT OR THAT SUCH ACTION OR PROCEEDING WAS BROUGHT IN AN INCONVENIENT COURT AND AGREES NOT TO PLEAD OR CLAIM THE SAME;

(iii) AGREES THAT SERVICE OF PROCESS IN ANY SUCH ACTION OR PROCEEDING MAY BE EFFECTED BY MAILING A COPY THEREOF BY REGISTERED OR CERTIFIED MAIL (OR ANY SUBSTANTIALLY SIMILAR FORM OF MAIL), POSTAGE PREPAID, TO ITS ADDRESS SET FORTH BENEATH ITS SIGNATURE HERETO OR AT SUCH OTHER ADDRESS OF WHICH THE LENDER SHALL HAVE BEEN NOTIFIED IN ACCORDANCE WITH SECTION 11.2; AND

(iv) AGREES THAT NOTHING HEREIN SHALL AFFECT THE RIGHT TO EFFECT SERVICE OF PROCESS IN ANY OTHER MANNER PERMITTED BY LAW OR SHALL LIMIT THE RIGHT TO SUE IN ANY OTHER JURISDICTION.

(b) Mutual Waiver of Jury Trial. EACH PARTY HERETO HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT, ANY OTHER LOAN DOCUMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY.

11.10 Costs and Expenses. Borrower promises to pay Lender’s fees and reasonable documented expenses necessary to finalize the loan documentation, including but not limited to reasonable and documented attorneys’ fees, UCC searches, filing costs, and other miscellaneous expenses (including with respect to due diligence). In addition, Borrower promises to pay any and all reasonable and documented attorneys’ and other professionals’ fees and expenses incurred by Lender after the Closing Date in connection with or related to: (a) the Loans; (b) the administration, collection, or enforcement of the Loans or any of the Loan Documents; (c) the amendment or modification of the Loan Documents; (d) any waiver, consent, release, or termination under the Loan Documents; (e) the protection, preservation, audit, field exam, sale, lease, liquidation, or disposition of Collateral or the exercise of remedies with respect to the Collateral; (f) any legal, litigation, administrative, arbitration, or out of court proceeding in connection with or related to Borrower or the Collateral, and any appeal or review thereof; and (g) any bankruptcy, restructuring, reorganization, assignment for the benefit of creditors, workout, foreclosure, or other action related to Borrower, the Collateral, the Loan Documents, including representing Lender in any adversary proceeding or contested matter commenced or continued by or on behalf of Borrower’s estate, and any appeal or review thereof.

11.11 Confidentiality. Lender acknowledges that certain items of Collateral and information provided to Lender by Borrower are confidential and proprietary information of Borrower, if and to the extent such information either (x) is marked as confidential by Borrower at the time of disclosure, or (y) should reasonably be understood to be confidential (the “Confidential Information”). Accordingly, Lender agrees that any Confidential Information it may obtain in the course of acquiring, administering, or perfecting Lender’s security interest in the Collateral shall not be disclosed to any other Person or entity in any manner whatsoever, in whole or in part, without the prior written consent of Borrower, except that Lender may disclose any such information: (a) to its own directors, officers, employees,

accountants, counsel and other professional advisors and to its Affiliates if Lender in its reasonable good faith discretion determines that any such party should have access to such information in connection with such party’s responsibilities in connection with the Loans or this Agreement and, provided that such recipient of such Confidential Information either (i) agrees to be bound by the confidentiality provisions of this paragraph or (ii) is otherwise subject to confidentiality restrictions that reasonably protect against the disclosure of Confidential Information which are no less restrictive than the terms of this Section 11.11; (b) if such information is generally available to the public; (c) if required or appropriate in any report, statement or testimony required by law or order of any Governmental Authority submitted to any governmental authority having or claiming to have jurisdiction over Lender, or requested by a bank examiner, regulatory examiner or self-regulatory examiner in the course of such examiner’s examination, inspection or audit; (d) if required or appropriate in response to any summons or subpoena or in connection with any litigation, to the extent permitted or deemed advisable by Lender’s counsel; or to comply with any legal requirement or law applicable to Lender; (f) to the extent reasonably necessary in connection with the exercise of any right or remedy under any Loan Document, including Lender’s sale, lease, or other disposition of Collateral after the occurrence of an Event of Default; (g) to any participant or assignee of Lender or any prospective participant or assignee; provided, that such participant or assignee or prospective participant or assignee agrees in writing to be bound by this Section prior to disclosure; or (h) otherwise with the prior written consent of Borrower; provided, that any disclosure made in violation of this Agreement shall not affect the obligations of Borrower or any of its Affiliates or any guarantor under this Agreement or the other Loan Documents.

11.12 Assignment of Rights. Borrower acknowledges and understands that Lender may, subject to Section 11.7, sell and assign all or part of its interest hereunder and under the Loan Documents to any (a) Affiliate of Lender; or (b) other Person or entity (other than a natural person) that is or will be engaged in the business of making, purchasing, holding or otherwise investing in commercial loans or similar extensions of credit in the ordinary course of its business (any such Person described in either clause (a) or clause (b), an “Assignee”). After such assignment the term “Lender” as used in the Loan Documents shall mean and include such Assignee, and such Assignee shall be vested with all rights, powers and remedies of Lender hereunder with respect to the interest so assigned; but with respect to any such interest not so transferred, Lender shall retain all rights, powers and remedies hereby given. No such assignment by Lender shall relieve Borrower of any of its obligations hereunder. Lender agrees that in the event of any transfer by it of the Note(s) (if any), it will endorse thereon a notation as to the portion of the principal of the Note(s), which shall have been paid at the time of such transfer and as to the date to which interest shall have been last paid thereon. Lender, acting solely for this purpose as an agent of the Borrower, shall maintain a register for the recordation of the names and addresses of the Lenders, and the Term Loan Commitments of, and principal amounts (and stated interest) of the Loans owing to, each Lender pursuant to the terms hereof from time to time (the “Register”). The entries in the Register shall be conclusive absent manifest error, and the Borrower and Lender shall treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement. The Register shall be available for inspection by the Borrower and Lender, at any reasonable time and from time to time upon reasonable prior notice.

11.13 Revival of Secured Obligations. This Agreement and the Loan Documents shall remain in full force and effect and continue to be effective if any petition is filed by or against Borrower for liquidation or reorganization, if Borrower becomes insolvent or makes an assignment for the benefit of creditors, if a receiver or trustee is appointed for all or any significant part of Borrower’s assets, or if any payment or transfer of Collateral is recovered from Lender. The Loan Documents and the Secured Obligations and Collateral security shall continue to be effective, or shall be revived or reinstated, as the case may be, if at any time payment and performance of the Secured Obligations or any transfer of Collateral to Lender, or any part thereof is rescinded, avoided or avoidable, reduced in amount, or must otherwise be restored or returned by, or is recovered from, Lender or by any obligee of the Secured

Obligations, whether as a “voidable preference,” “fraudulent conveyance,” or otherwise, all as though such payment, performance, or transfer of Collateral had not been made. In the event that any payment, or any part thereof, is rescinded, reduced, avoided, avoidable, restored, returned, or recovered, the Loan Documents and the Secured Obligations shall be deemed, without any further action or documentation, to have been revived and reinstated until the Secured Obligations (other than contingent obligations for which no claim has been asserted) are fully satisfied.

11.14 Counterparts. This Agreement and any amendments, waivers, consents or supplements hereto may be executed in any number of counterparts, and by different parties hereto in separate counterparts, each of which when so delivered shall be deemed an original, but all of which counterparts shall constitute but one and the same instrument. Delivery of an executed counterpart signature page of this Agreement by telecopier or other electronic means shall be effective as delivery of a manually executed counterpart of this Agreement.

11.15 No Third-Party Beneficiaries. No provisions of the Loan Documents are intended, nor will be interpreted, to provide or create any third-party beneficiary rights or any other rights of any kind in any Person other than Lender and Borrower unless specifically provided otherwise herein, and, except as otherwise so provided, all provisions of the Loan Documents will be personal and solely among Lender, the Lender and the Borrower.

11.16 Publicity. None of the parties hereto nor any of its respective member businesses and Affiliates shall, without the other parties’ prior written consent (which shall not be unreasonably withheld or delayed), publicize or use (a) the other party’s name (including a brief description of the relationship among the parties hereto), logo or hyperlink to such other parties’ web site, separately or together, in written and oral presentations, advertising, promotional and marketing materials, client lists, public relations materials or on its web site (together, the “Publicity Materials”); (b) the names of officers of such other parties in the Publicity Materials; and (c) such other parties’ name, trademarks, servicemarks in any news or press release concerning such party; provided however, notwithstanding anything to the contrary herein, no such consent shall be required (i) to the extent necessary to comply with the requests of any regulators, legal requirements or laws applicable to such party, pursuant to any listing agreement with any national securities exchange (so long as such party provides prior notice to the other party hereto to the extent reasonably practicable) and (ii) to comply with Section 11.11.

11.17 Multiple Borrowers.

(a) Borrower’s Agent. Each of the Borrowers hereby irrevocably appoints Lead Borrower as its agent, attorney-in-fact and legal representative for all purposes, including requesting disbursement of the Term Loan and receiving account statements and other notices and communications to Borrowers (or any of them) from the Lender. The Lender may rely, and shall be fully protected in relying, on any Advance Request, disbursement instruction, report, information or any other notice or communication made or given by Lead Borrower, whether in its own name or on behalf of one or more of the other Borrowers, and the Lender shall not have any obligation to make any inquiry or request any confirmation from or on behalf of any other Borrower as to the binding effect on it of any such request, instruction, report, information, other notice or communication, nor shall the joint and several character of the Borrowers’ obligations hereunder be affected thereby.

(b) Waivers. Each Borrower hereby waives: (i) any right to require the Lender to institute suit against, or to exhaust its rights and remedies against, any other Borrower or any other person, or to proceed against any property of any kind which secures all or any part of the Secured Obligations, or to exercise any right of offset or other right with respect to any reserves, credits or deposit accounts held by or maintained with Lender or any Indebtedness of Lender to any other Borrower, or to exercise any other

right or power, or pursue any other remedy Lender may have; (ii) any defense arising by reason of any disability or other defense of any other Borrower or any guarantor or any endorser, co-maker or other person, or by reason of the cessation from any cause whatsoever of any liability of any other Borrower or any guarantor or any endorser, co-maker or other person, with respect to all or any part of the Secured Obligations, or by reason of any act or omission of the Lender or others which directly or indirectly results in the discharge or release of any other Borrower or any guarantor or any other person or any Secured Obligations or any security therefor, whether by operation of law or otherwise; (iii) any defense arising by reason of any failure of the Lender to obtain, perfect, maintain or keep in force any Lien on, any property of any Borrower or any other person; (iv) any defense based upon or arising out of any bankruptcy, insolvency, reorganization, arrangement, readjustment of debt, liquidation or dissolution proceeding commenced by or against any other Borrower or any guarantor or any endorser, co-maker or other person, including without limitation any discharge of, or bar against collecting, any of the Secured Obligations (including without limitation any interest thereon), in or as a result of any such proceeding. Until all of the Secured Obligations have been paid, performed, and discharged in full, nothing shall discharge or satisfy the liability of any Borrower hereunder except the full performance and payment of all of the Secured Obligations. If any claim is ever made upon the Lender for repayment or recovery of any amount or amounts received by the Lender in payment of or on account of any of the Secured Obligations, because of any claim that any such payment constituted a preferential transfer or fraudulent conveyance, or for any other reason whatsoever, and the Lender repays all or part of said amount by reason of any judgment, decree or order of any court or administrative body having jurisdiction over the Lender or any of its property, or by reason of any settlement or compromise of any such claim effected by the Lender with any such claimant (including without limitation any other Borrower), then and in any such event, each Borrower agrees that any such judgment, decree, order, settlement and compromise shall be binding upon such Borrower, notwithstanding any revocation or release of this Agreement or the cancellation of any note or other instrument evidencing any of the Secured Obligations, or any release of any of the Secured Obligations, and each Borrower shall be and remain liable to Lender under this Agreement for the amount so repaid or recovered, to the same extent as if such amount had never originally been received by Lender, and the provisions of this sentence shall survive, and continue in effect, notwithstanding any revocation or release of this Agreement. Each Borrower hereby expressly and unconditionally waives all rights of subrogation, reimbursement and indemnity of every kind against any other Borrower, and all rights of recourse to any assets or property of any other Borrower, and all rights to any collateral or security held for the payment and performance of any Secured Obligations, including (but not limited to) any of the foregoing rights which Borrower may have under any present or future document or agreement with any other Borrower or other person, and including (but not limited to) any of the foregoing rights which any Borrower may have under any equitable doctrine of subrogation, implied contract, or unjust enrichment, or any other equitable or legal doctrine.

(c) Consents. Each Borrower hereby consents and agrees that, without notice to or by Borrower and without affecting or impairing in any way the obligations or liability of Borrower hereunder, the Lender may, from time to time before or after revocation of this Agreement, do any one or more of the following in its sole and absolute discretion: (i) accept partial payments of, compromise or settle, renew, extend the time for the payment, discharge, or performance of, refuse to enforce, and release all or any parties to, any or all of the Secured Obligations; (ii) grant any other indulgence to any Borrower or any other Person in respect of any or all of the Secured Obligations or any other matter; (iii) accept, release, waive, surrender, enforce, exchange, modify, impair, or extend the time for the performance, discharge, or payment of, any and all property of any kind securing any or all of the Secured Obligations or any guaranty of any or all of the Secured Obligations, or on which the Lender at any time may have a Lien, or refuse to enforce its rights or make any compromise or settlement or agreement therefor in respect of any or all of such property; (iv) substitute or add, or take any action or omit to take any action which results in the release of, any one or more other Borrowers or any endorsers or guarantors of all or any part of the Secured Obligations, including, without limitation one or more

parties to this Agreement, regardless of any destruction or impairment of any right of contribution or other right of Borrower; (v) apply any sums received from any other Borrower, any guarantor, endorser, or co-signer, or from the disposition of any Collateral or security, to any Indebtedness whatsoever owing from such person or secured by such Collateral or security, in such manner and order as the Lender determines in its sole discretion, and regardless of whether such Indebtedness is part of the Secured Obligations, is secured, or is due and payable. Each Borrower consents and agrees that the Lender shall be under no obligation to marshal any assets in favor of Borrower, or against or in payment of any or all of the Secured Obligations. Each Borrower further consents and agrees that the Lender shall have no duties or responsibilities whatsoever with respect to any property securing any or all of the Secured Obligations. Without limiting the generality of the foregoing, the Lender shall have no obligation to monitor, verify, audit, examine, or obtain or maintain any insurance with respect to, any property securing any or all of the Secured Obligations.

(d) Independent Liability. Each Borrower hereby agrees that one or more successive or concurrent actions may be brought hereon against such Borrower, in the same action in which any other Borrower may be sued or in separate actions, as often as deemed advisable by Lender. Each Borrower is fully aware of the financial condition of each other Borrower and is executing and delivering this Agreement based solely upon its own independent investigation of all matters pertinent hereto, and such Borrower is not relying in any manner upon any representation or statement of Lender with respect thereto. Each Borrower represents and warrants that it is in a position to obtain, and each Borrower hereby assumes full responsibility for obtaining, any additional information concerning any other Borrower’s financial condition and any other matter pertinent hereto as such Borrower may desire, and such Borrower is not relying upon or expecting the Lender to furnish to it any information now or hereafter in the Lender’s possession concerning the same or any other matter.

(e) Subordination. All Indebtedness of a Borrower now or hereafter arising held by another Borrower is subordinated to the Secured Obligations and the Borrower holding the Indebtedness shall take all actions reasonably requested by Lender to effect, to enforce and to give notice of such subordination.

11.18 Patriot Act. Lender hereby notifies each Borrower that pursuant to the requirements of the Patriot Act, it is required to obtain, verify and record information that identifies each Borrower, which information includes the name and address of such Borrower and other information that will allow such Lender to identify such Borrower in accordance with the Patriot Act.
