   Multilink elects to continue in possession of the remainder of the Premises
   TRW shall restore, at Multinlink's own cost and expense, the improvements on
   the remainder of the Premises to a condition making the Premises tenantable
   by Multilink for the uses permitted by this Agreement. Any rent payable under
   this Agreement after the date actual physical possession is taken by the
   condemnor of the portion of the Premises condemned shall be reduced by the
   percentage the ground area of the portion taken by eminent domain bears to
   the total ground area of the Premises on the date of this Agreement. In
   addition, the rent payable under this Agreement shall be further abated
   during the time and to the extent Multilink is prevented from occupying all
   of the remainder of the Premises by the work of restoration required by this
   section to be performed by TRW.

no dealings with any real estate broker or agent in connection with the

Section 12.17. Notwithstanding anything to the contrary set forth in this
Agreement, TRW shall be in default in the performance of any obligation required
to be performed by TRW pursuant to this Agreement if TRW fails to perform such
obligation within thirty (30) days after the receipt of notice from Multilink
specifying in detail TRW's failure to perform; provided, however, if the nature
of TRW's obligation is such that more than thirty (30) days after required for
its performance, then TRW shall not be in default under this Agreement if it
shall commence such performance within such thirty (30) day period and
thereafter diligently pursue the same to completion. Upon any such default by
TRW under this Agreement, Multilink may exercise any of its rights provided at
law or in equity.

                               Abatement of Fees

Section 12.18. In the event that Multilink is prevented by acts of TRW from
using, and does not use, the Premises or any portion thereof for five (5)
consecutive business days (the "Eligibility Period"), then the fees payable by
Multilink under this Agreement shall be abated or reduced, as the case may be,
after expiration of the Eligibility Period for such time that Multilink
continues to be so prevented from using, and does not use, the Premises or a
portion thereof, in the proportion that the area of the portion of the Premises
that Multilink is prevented from using, and does not use, bears to the total
area of the premises; provided, however, in the event that Multilink is
prevented from using, and does not use, a portion of the Premises for a period
of time in excess of the Eligibility Period and the remaining portion of the
Premises is not sufficient to allow Multilink to effectively conduct its
business therein, and if Multilink does not conduct its business from such
remaining portion, then for such time after expiration of the Eligibility Period
during which Multilink is so prevented from effectively conducting its business
therein, the fees payable by Multilink under this Agreement shall be abated for
such time as Multilink continues to be so prevented from using, and does not
use, the Premises. To the extent Multilink is entitled to abatement without
regard to the Eligibility Period, because of an event described in Article 6
above, then the Eligibility Period shall not be applicable. If Multilink is
prevented from using and does not use all or a material portion of the Premises
for three (3) months following the Eligibility Period, then Multilink shall
thereafter have the right to terminate this Agreement upon written notice to
TRW.
