This Agreement shall require that the Receiving Parties exercise the same degree of care to guard against unauthorized disclosure or use of such Proprietary Information as Receiving Parties employ with respect to their own Proprietary Information of like importance, but in no event, less than a reasonable degree of care. This Agreement shall also require that the Receiving Parties make the Proprietary Information available only to those of their employees or agents having a "need to know" in order to operate or maintain the Satellite; and further, that each of their employees or agents shall be advised that they are obligated to protect the Proprietary Information in a manner consistent with the Agreement.

In the event AMSC, the Lessee or Operator of the Satellite is acquired by a competitor of Hughes, the Parties agree that Hughes would be irreparably harmed if any competitor of Hughes, as determined by Hughes in its reasonable discretion, were to acquire access to any of the intellectual property, Proprietary Information or other technology, data or inventions covered under the Contract (collectively, the "Intellectual Property"), regardless of whether such competitor has an ownership interest in AMSC, the Lessee or Operator.
