                  (whether as to payment time performance or otherwise
                  howsoever) which might but for this provision have any such
                  effect or by reason of any variation in the terms of the Note
                  Purchase Agreement or any other related agreement thereto or
                  any of them or by reason of the unenforceability invalidity or

                  enter into and perform their respective obligations thereunder
                  and should any obligation or purported obligation of any such
                  other party which if enforceable or valid or continuing would
                  be secured by this Agreement be or become wholly or in part
                  unenforceable or invalid or terminated for any reason
                  whatsoever the Pledgor shall keep the Pledgee and the Security
                  Agent fully indemnified against any loss suffered by the
                  Pledgee or the Security Agent as a result of any failure by

                  rights of subrogation and agrees not to demand or accept
                  repayment in whole or in part of any loan or advances at any
                  time owing to the Pledgor from NOC or to demand or accept any
                  security in respect thereof or to assign the same or charge
                  the same as security or to take any step to enforce any rights
                  against NOC or to claim or prove in competition with the
                  Pledgee or have the benefit of any share in any payment or
                  composition from NOC or any

                  other person or in any other guarantee or security now or
                  hereafter held by the Pledgee.

10.02             On the Termination Date, the Pledgee shall, at the Pledgor's
                  request, discharge the security interest created by this
                  Agreement and the Security Agent shall return the Pledged
                  Shares to the Pledgor, in a form transferable by delivery,
                  free and clear of all Encumbrances arising by, through or
                  under the Security Agent or the Pledgee, and in connection
                  therwith shall take such actions and shall execute and deliver

         jurisdiction, whether concurrently or not.

any right or power hereunder shall operate as a waiver thereof, nor shall any
single or partial exercise of any such right or power, or any abandonment or
discontinuance of steps to enforce such right or power, preclude any other or
further exercise thereof or the exercise of any other right or power.

                                       12
