         however,  that the disclosing  party shall first have made a good faith
         effort to obtain a  protective  order  requiring  that the  information
         and/or  documents  so  disclosed be used only for the purpose for which
         the order was issued; or

and  MICROSEMI  shall retain any and all fights to file any patent  applications
thereon.

9.2 All discoveries,  improvements,  inventions,  and trade secrets, made in the
performance of this Agreement solely by MOTOROLA personnel shall be the sole and
exclusive  property  of  MOTOROLA  subject to the  licenses  granted  herein and
MOTOROLA  shall  retain  any and all  rights  to file  any  patent  applications
thereon.

9.3 All discoveries,  improvements,  inventions,  and trade secrets, made in the
performance  of this  Agreement  jointly by  MOTOROLA  personnel  and  MICROSEMI
personnel,  shall be the property jointly of MOTOROLA and MICROSEMI,  each party
having an equal and undivided one-half (1/2) interest therein.

9.4 In the case of each  discovery,  improvement  or invention  jointly owned by
MOTOROLA and MICROSEMI in accordance with Paragraph 9.3, MOTOROLA shall have the
first right of election to file  patent  applications  in the United  States and
other  countries.  MOTOROLA shall notify  MICROSEMI in writing,  at the earliest
practicable date, whether or not, and in which countries of the world,  MOTOROLA
elects to file such patent  application.  MICROSEMI shall have the right to file
patent  applications  on such  discovery,  improvement or invention in all other
countries. Each party, at its own expense, shall cooperate fully with the filing
party as may be necessary for the proper preparation,  filing and prosecution of
each such patent  application and the  maintenance,  renewal and defense of each
patent  covering  such  discovery,  improvement  or  invention.  The expense for
preparing,  filing and prosecuting each joint  application,  and for issuance of
the  respective  patent shall be borne by the party which prepares and files the
application. Where such joint application for patent is filed by either party in
a country  which  requires the payment of annual taxes or annuities on a pending
application or on an issued  patent,  the filing party,  prior to filing,  shall
notify the other party,  requesting the other party to indicate  whether it will
agree to pay one-half (1/2) of such annual taxes or annuities.  If, within sixty
(60) days after receiving such notice,  the non-filing  party fails to assume in
writing the  obligation to pay its one-half  (1/2) share of such annual taxes or
annuities,  or if either  party  subsequently  fails,  within sixty (60) days of
demand,  to continue such payments,  it shall forthwith  relinquish to the other
party,  providing said other party continues such payments, its right, title and
interest to such  application and patent,  subject,  however,  to retention of a
paid-up, nonexclusive,  nonassignable and irrevocable license, without the right
to grant sublicenses,  in favor of the relinquishing  party, to make, have made,
use, lease,  sell, or otherwise  dispose of apparatus and/or use or practice any
methods under said application and patent.

9.5 In the event that the filing party shall determine to abandon,  or otherwise
not to  prosecute,  any jointly  owned patent  application,  or not to maintain,
defend or renew any  jointly  owned  patent,  it shall  notify  the other  party
thereof,  in writing,  at the earliest  practicable  date,  and such other party
shall have the right, at its expense,  to prosecute such  application or to take
up such maintenance or defense,  or prosecute such renewal,  as the case may be.
The filing party agrees,  at the other party's expense,  to cooperate fully with
the other party to assist the other party in obtaining,  maintaining,  defending
and renewing such patent right hereunder.  Thenceforth, the party exercising its
right under this  Paragraph  9.5 shall be deemed "the filing party" for purposes
of Paragraphs 9.4 and 9.5.

9.6 Each party  shall have the right to grant  nonexclusive  licenses  under any
terms and conditions that it desires under each jointly owned patent application
or patent, provided that it shall have fulfilled its obligation,  if any, to pay
its share of taxes or annuities  imposed on such pending  application or patent,
and such party  shall  retain any  consideration  that it may  receive  therefor
without  having to account to the other joint owner.  Each party consents to the
granting of such  nonexclusive  licenses by the other  party,  and agrees not to
assert any claim with respect to any such patent or application  licensed by the
other party  against the licensee or licensees  thereunder  for the terms of any
such license.








9.7 The rights and obligation of this Section 9 regarding the ownership, filing,
prosecution,  and  maintenance  of  Inventions  shall  survive  the  expiration,
cancellation, or termination of this Agreement.
