(a)bear and pay the cost reasonably incurred by that undertaker in making good such damage or restoring the supply; and
(b)make reasonable compensation to that undertaker for any other expenses, loss, damages, penalty or costs incurred by the undertaker,
by reason or in consequence of any such damage or interruption.
(2) Nothing in sub-paragraph (1) imposes any liability on Network Rail with respect to any damage or interruption to the extent that it is attributable to the act, neglect or default of an undertaker, its officers, servants, contractors or agents.
(3) An undertaker must give Network Rail reasonable notice of any such claim or demand and no settlement or compromise is to be made without the consent of Network Rail, which, if it withholds such consent, has the sole conduct of any settlement or compromise or of any proceedings necessary to resist the claim or demand.
