A.
A franchise agreement may provide that, prior to the franchise's becoming effective, the grantee shall post with the Town a cash security deposit to be used as a security fund to ensure the grantee's faithful performance of and compliance with all provisions of this chapter, the franchise agreement, and other applicable laws and compliance with all orders, permits, and directions of the Town or any agency thereof having jurisdiction over the grantee's acts or defaults under the franchise and the payment by the grantee of any claims, liens, fees, or taxes due the Town which arise by reason of the construction, operation, or maintenance of the system. The amount of any security fund shall be specified in a franchise agreement.
B.
In lieu of a cash security fund, a grantee may agree to file and maintain with the Town an irrevocable letter of credit with a bank having an office in the State of Maine in the amount specified in the preceding subsection to serve the same purposes as set forth therein. Said letter of credit shall remain in effect for the full term of the franchise plus an additional six months thereafter. The grantee and its surety shall be jointly and severally liable under the terms of the letter of credit for the grantee's failure to ensure its faithful performance of and compliance with all provisions of this chapter, the franchise agreement, and other applicable law and compliance with all orders, permits, and directions of the Town and the payment by the grantee of any claims, liens, fees, or taxes due the Town which arise by reason of the construction, operation, or maintenance of the system. The letter of credit shall provide for 30 days' prior written notice to the Town of any intention on the part of the grantee to cancel, fail to renew, or otherwise materially alter its terms. Neither the filing of a letter of credit with the Town nor the receipt of any damages recovered by the Town thereunder shall be construed to excuse faithful performance by the grantee or limit the liability of the grantee under the terms of its franchise for damages, either to the full amount of the letter of credit or otherwise.
