action in any court in the United States or any other jurisdiction, Cadence shall deliver an Unauthorized Use Notice to the alleged user and, in all circumstances, Avant! and Synopsys, describing with particularity the basis for Cadence’s
belief, and requesting that such use cease.

before the Response Date corresponding to that Unauthorized Use Notice, with a copy to all recipients of the Unauthorized Use Notice. Such recipient shall not commence an action for declaratory relief with respect to the use alleged in the
Unauthorized Use Notice. If the response to the Unauthorized Use notice states that the recipient has ceased or intends to cease the use alleged within 90 days of such response (which period may be extended for an additional period of 90 days for
good cause shown), and thereafter timely certifies that such use has ceased, then the Party that delivered the Unauthorized Use Notice shall have no legal or equitable remedy whatever with respect to such use for so long the use does not recommence.
If the use recommences, or if the user has not genuinely ceased its allegedly unauthorized use, despite a certification, or if the response to the Unauthorized Use Notice states neither that the recipient has ceased nor intends to cease the use
alleged in the Unauthorized Use Notice, the sole and exclusive remedies of the sender of the Unauthorized Use Notice shall be as provided for in section 6(b), section 6(c) and section 6(d) of this Agreement.
