(2) "Mission-essential functions" means those organizational activities that must be performed under all circumstances to achieve DoD component missions or responsibilities, as determined by the appropriate functional commander or civilian equivalent.

(d)(1) Notwithstanding any other clause of this contract, the contractor shall be responsible to perform those services identified as essential contractor services during crisis situations (as directed by the Contracting Officer), in accordance with its Mission-Essential Contractor Services Plan.

(2) In the event the Contractor anticipates not being able to perform any of the essential contractor services identified in accordance with paragraph (b) of this section during a crisis situation, the Contractor shall notify the Contracting Officer or other designated representative as expeditiously as possible and use its best efforts to cooperate with the Government in the Government's efforts to maintain the continuity of operations.

(e) The Government reserves the right in such crisis situations to use Federal employees, military personnel or contract support from other contractors, or to enter into new contracts for essential contractor services.

The Contractor's notice shall include the Contractor's proposal for an equitable adjustment and any data supporting the increase or decrease in the form prescribed by the Contracting Officer. The parties shall negotiate an equitable price adjustment to the contract price, delivery schedule, or both as soon as is practicable after receipt of the Contractor's proposal.
