TRANSMITTAL RECORD.  Information which is confidential (hereinafter 
referred to as "Confidential Information") to a party hereto, including 
information which is MICROSEMI TECHNICAL INFORMATION and/or MOTOROLA 
TECHNICAL INFORMATION, shall be disclosed as follows.  When such is 
disclosed in writing and accepted, such writing should state the date of

which it does not desire to publish, disclose, or disseminate.  
Notwithstanding the expiration of the obligation to exert the above 
standard of care, the receiving party may not transfer such Confidential 
Information or any portion thereof to a third party.  If Confidential

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

8.5.2	otherwise required by law.

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.

written approval of the other party except as required by law, or by 
government regulation, requirement or order, or as may be necessary to 
establish or assert its rights hereunder.

All notices to third parties and all other publicity concerning this 
Agreement shall be jointly planned and coordinated by the parties.  
Neither party shall act unilaterally in this regard without the prior 
written approval of the other party, which approval, however, shall not 
unreasonably be withheld.

The parties acknowledge and agree that this Agreement is to be entered 
into contemporaneously with the MOTOROLA - MICROSEMI POOWERMITE SERVICES 
AGREEMENT.  However, if for any reason the MOTOROLA - MICROSEMI 
POOWERMITE SERVICES AGREEMENT is not signed and finalized and this
