Guarantee and indemnity
Each Guarantor irrevocably and unconditionally jointly and severally:
(a) guarantees to each Finance Party punctual performance by each Borrower of all that Borrowers obligations under the Finance Documents;
(b) undertakes with each Finance Party that whenever a Borrower does not pay any amount when due under or in connection with any Finance Document, that Guarantor shall within five Business Days of receiving a demand pay that amount as if it was the principal obligor; and
(c) indemnifies each Finance Party within five Business Days of receiving a demand against any cost, loss or liability reasonably incurred or suffered and documented by that Finance Party if any obligation guaranteed by it is or becomes unenforceable, invalid or illegal. The amount of the cost, loss or liability shall be equal to the amount which that Finance Party would otherwise have been entitled to recover.
