If Seller

(e) The Outside Date (i) shall be extended by the number of days that the Guaranteed Substantial Completion Date is extended pursuant to the terms and conditions of the EPC Agreement as a result of a Force Majeure Event and (ii) may be extended by Seller until April 30, 2023 if the failure to achieve Final Completion relates to any critical component or equipment for the Interconnection Electric Facilities, including the transformer, 345-kV breaker, support steel or switches.

Section 1.02 Purchase Price. Following the Closing Date, in the event the EPC Agreement Assignment has not occurred pursuant to Section 1.01(b) and the Interconnection Electric Facilities have not been transferred pursuant to Section 1.01(c), Buyer shall pay Seller for the Interconnection Electric Facilities in accordance with the timing and amounts (such amounts, in the aggregate, the “Purchase Price”) set forth on Exhibit B attached hereto.

For the avoidance of doubt, Buyer shall be responsible for all operation and maintenance expenses relating to the Interconnection Electric Facilities, including expenses relating to NERC reporting, maintenance of the Interconnection Electric Facilities pursuant to the Original Equipment Manufacturer (the “OEM”) manual, oil and fluid testing pursuant to the OEM specifications, and maintenance of the fence and grounds of the Interconnection Electric Facilities.

Section 1.03 Security Interest.

(a) The parties acknowledge and agree that, prior to the date hereof, Buyer has provided security in the form of a cash deposit into a segregated account of Seller or one of its Affiliates in the amount of Four Hundred Thousand Dollars ($400,000.00). No later than three (3) Business Days after the date hereof, Buyer will provide security in the form of cash or a Letter of Credit in the amount of One Million One Hundred Thirty One Thousand Five Hundred Ten Dollars ($1,131,510.00). No later than three (3) Business Days after Buyer receives notice from Seller that Seller or one of its Affiliates has executed the EPC Agreement, Buyer will provide security in the form of cash or a Letter of Credit in the amount of One Million Five Hundred Thirty One Thousand Five Hundred Ten Dollars ($1,531,510.00) (the amount of security in the preceding two sentences, together with the amount of security reflected in this sentence, collectively, the “Interconnection Electric Facilities Cash Collateral”). In addition, the Buyer will give the Seller a first lien on the Interconnection Electric Facilities (the “Equipment Collateral”, together with the Interconnection Electric Facilities Cash Collateral, the “Interconnection Electric Facilities Collateral”). The amount of the Interconnection Electric Facilities Cash Collateral will decrease by 20% after each year of the PPA.

(b) Effective at the dates specified in Section 1.03(a) with respect to Interconnection Electric Facilities Cash Collateral (as applicable), Buyer hereby grants Seller a present and continuing security interest, and lien on (and right of setoff against), and collateral assignment of, the Interconnection Electric Facilities Cash Collateral to the extent provided in the form of cash and with respect to any proceeds of a Letter of Credit. Effective on the Closing Date, Buyer hereby grants Seller a present and continuing security interest, and lien on (and right of setoff against), and collateral assignment of, the Equipment Collateral. On or prior to the Closing Date, Buyer and Seller will enter into the Security Agreement in the form attached hereto as Exhibit C. If Buyer does not pay the “Payment Amount” in accordance with the terms of Section 1.02 or otherwise breaches or defaults under this Agreement, then the Seller may: (A) in respect to the Interconnection Electric Facilities Cash Collateral (i) exercise any rights and remedies available to the Seller, including any such rights and remedies under law then in effect; (ii) exercise its rights of setoff against any and all Interconnection Electric Facilities Cash Collateral; and (iii) draw on any outstanding Letter of Credit issued for its benefit, in each case, free from any claim or right of any nature whatsoever of the Buyer; and (B) in respect to the Equipment Collateral, exercise any and all rights and remedies as a secured party. The Seller shall apply the proceeds of the Interconnection Electric Facilities Collateral realized upon the exercise of any such rights or remedies to reduce the Buyer’s obligations under this Agreement (the Buyer remaining liable for any amounts owing to the Seller after such application), subject to the Seller’s obligation to return any surplus proceeds remaining after such obligations are satisfied in full. In the event (i) the Closing Date has not occurred by the Outside Date, (ii) Buyer has made an election pursuant to Section 1.01(b) or Section 1.01(c) (as applicable), and (iii) Buyer has complied with and fulfilled all of its obligations pursuant to Section 1.01(b) or Section 1.01(c) (as applicable), including all payment obligations thereunder, the security interest granted hereby with respect to the Interconnection Electric Facilities Cash Collateral shall terminate and all rights with respect to the Interconnection Electric Facilities Cash Collateral shall revert to Buyer.

(c) Costs of a Letter of Credit shall be borne by the applicant for such Letter of Credit. In the event Buyer posts a Letter of Credit as collateral, such Letter of Credit shall be in a form reasonably acceptable to the Seller, valid for a period of at least one year from issuance, and in an amount not less than the then-applicable amount of the Interconnection Electric Facilities Cash Collateral as may be modified pursuant to this Section 1.03. Unless such obligations are waived by the beneficiary, a Letter of Credit must state that the issuing bank shall renew such letter automatically for successive one-year periods. The Buyer shall cause the renewal, extension, or replacement of any Letter of Credit, as applicable, at least thirty (30) Days before expiration or at least five (5) Business Days following a downgrade of the issuing bank such that it no longer qualifies to issue a Letter of Credit, as such rating threshold is described in the definition of “Letter of Credit”. If Buyer has not caused the renewal, extension, or replacement of a Letter of Credit by the time limits provided above, then the Seller shall have the right to draw upon the undrawn amount under the Letter of Credit. In the event that the Seller draws on any portion of the Letter of Credit, the Buyer shall replenish such Interconnection Electric Facilities Collateral up to the amount required by this Section 1.03 within five (5) Business Days after the Seller makes any draw thereon as authorized by this Agreement or the terms of such Letter of Credit.

(d) The parties acknowledge and agree that any continuing Event of Default (as defined in the PPA) shall constitute a breach and default by Buyer of its obligations pursuant to this Agreement.

Section 1.04 Repurchase of Interconnection Electric Facilities. At the end of the Term (as defined in the Lease Agreement) (the “Repurchase Date”), Buyer shall sell, assign, transfer, convey and deliver to Seller, and Seller shall purchase from Buyer, all of Buyer’s right, title and interest in the Interconnection Electric Facilities free and clear of any mortgage, pledge, lien, charge, security interest, claim or other encumbrance for the Interconnection Electric Facilities Repurchase Price. The “Interconnection Electric Facilities Repurchase Price” shall be determined as follows: Seller shall obtain bids for the Interconnection Electric Facilities from five (5) brokers unaffiliated with Seller reasonably acceptable to Buyer that are in the business of supplying electrical equipment in the secondary market, from which bids Seller shall discard the high and the low, and the Interconnection Electric Facilities Repurchase Price shall be an amount equal to the average of the remaining three (3) bids. Within thirty (30) days of the determination of the Interconnection Electric Facilities Repurchase Price, Seller shall pay the Interconnection Electric Facilities Repurchase Price to Buyer by wire transfer of immediately available funds pursuant to wire transfer instructions provided by Buyer to Seller. On the Repurchase Date, the parties shall execute a xxxx of sale in the form of Exhibit A hereto and such other customary instruments of sale, transfer, assignment and conveyance in form and substance reasonably satisfactory to the parties, as may be required to give effect to this Agreement.
