12.4 INDEMNIFICATION: (a) In the event any product to be furnished under this

manufacturing specifications designated by Buyer, but rather is the design of
Seller, Seller agrees that it shall, at its own expense and at its option,
defend or settle any claim, suit, or proceeding brought against Buyer or any
customer of Buyer, based on an allegation that the product furnished under this
Agreement constitutes a direct or a contributory infringement of any claim of
any patent, mask work, copyright or any other intellectual property right. This
obligation shall be effective only if Buyer shall have made all payments then
due and if Seller is notified of said allegation promptly in writing and given
authority, information, and assistance for the settlement or defense of said
claim, suit, or proceeding. Seller shall pay all damages and costs assessed in
such suit or proceedings. In the event of a final adjudication by a court of
competent jurisdiction that its product or any part thereof infringes or
violates any third party intellectual property right or if the use or sale
thereof is enjoined, or if the provisions of any negotiated settlement Agreement
prohibit the use of the product, Seller shall at its sole option and its own
expense, either: (a) procure for Buyer the right to continue using the product;
or (b) replace it with a substantially equivalent non-infringing product; or (c)
modify it so it becomes non-infringing but substantially equivalent; or (d) if
none of the above is reasonably available, terminate the Buyer's right to use
the product, accept the return of the product from Buyer, and return to the
Buyer the price originally paid by Buyer to Seller for the product supplied by
Seller.

The foregoing indemnity does not apply to the following: (1) infringement by a
combination of products furnished under this Agreement with other products not
furnished hereunder unless Seller is a contributory infringer; (2) infringement
resulting from changes or modifications made to or from the product by the
Buyer; and (3) any settlements of a claim, suit, or proceeding made without
Seller's written consent.

The foregoing states the entire liability of Seller with respect to infringement
or violation of third party intellectual property rights in connection with
products furnished under this Agreement.

               (a) In the event any product to be furnished under this Agreement
is to be made in accordance with drawings, samples or manufacturing
specifications designated by Buyer and is not the design of Seller, Buyer agrees
to defend, indemnify and hold Seller harmless to the same extent


                                       -9-
<PAGE>   10

                              INTELLECTUAL PROPERTY

15.1 PROPRIETARY INFORMATION: For the purpose of this Agreement:

               (a) "Proprietary Information" shall mean all drawings, documents,
ideas, know-how and other information supplied by one Party ("Disclosing Party")
to another ("Recipient") (whether disclosed orally, or in documentary form, by
demonstration or otherwise) for the purpose of achieving the objectives of this
Agreement.

               (b) "Proper Use" shall mean use of the Proprietary Information
solely by the Recipient for the objectives of this Agreement.

15.2 NONDISCLOSURE: Buyer and TRW each agree to employ reasonable efforts to
keep in confidence and prevent the disclosure to any person(s) outside their
respective organizations or any person(s) within their organizations not having
a need to know, all information received from the other which is designated in
writing or by appropriate stamp or legend to be of a proprietary nature
(hereafter "Proprietary Information") and neither will use Proprietary
Information for purposes other than the Purpose; provided, however, neither
party will be liable for disclosure or use of such information if the same is:

        (a) In the public domain at the time of disclosure, or is subsequently
made available to the general public without restriction by the disclosing
party;

        (b) known to the Recipient at the time of disclosure without
restrictions on its use or independently developed by the Recipient, and there

<PAGE>   12

If any portion of Proprietary Information falls within any one of these
exceptions, the remainder shall continue to be subject to the foregoing
prohibitions and restrictions. The Recipient of Proprietary Information shall
inform its employees of the confidential nature of the Proprietary Information
and shall prohibit them from making copies of any of it except where such copies
are necessary for the purposes of Proper Use, unless agreed upon by the
Disclosing Party.

Each party shall protect the Proprietary Information of the other party using
the same degree of care, but no less than a reasonable degree of care, to
prevent the unauthorized use, dissemination or publication of the confidential
information as that party uses to protect its own Proprietary Information of
comparable importance.

Prior to disclosure of Proprietary Information to any employee, each party shall
fully advise such employee that he or she is required to hold in confidence all
information and that such information is not to be disclosed to persons outside
his or her organization or to any co-employees not directly concerned with
furthering the Purpose. The parties shall maintain between themselves and their
officers, employees and consultants duly binding agreements by such persons as
may be necessary to fulfill their obligations under this Agreement.

15.3 MARKING: Proprietary Information made available in written form by one
Party to another Party shall be marked with the legend:

                      "PROPRIETARY INFORMATION"
           or         "TRW PROPRIETARY INFORMATION"

as the case may be, or an equivalent conspicuous legend. No sheet or page of any
written material shall be so labeled which is not, in good faith, believed by
the Disclosing Party to contain Proprietary Information. A Recipient of
Proprietary Information hereunder shall have no obligation with respect to any
portion of any written material which is not so labeled or any information
received orally unless it is identified as proprietary and a written summary of
such oral communication, specifically identifying the items of Proprietary
Information, is furnished to the Recipient within thirty (30) days of such
disclosure.

The individuals identified below are the only persons authorized to receive
Proprietary information on behalf of the Parties:

        For Buyer:    Mr. John Ocampo

        For TRW:      Dr. Tom Joseph

By written notice to the other Party, these representatives may be replaced by
another person from the same Party.

15.4 JUDICIAL ORDERS: In the event any governmental or judicial order requires
the disclosure of Proprietary Information, the Recipient of such Proprietary
Information shall promptly but in any event prior to such disclosure notify the
originator of the Proprietary Information of the requirement and provide
reasonable aid and assistance if the originator decides to oppose such
governmental or judicial order. Recipient shall not be liable for any disclosure
of Proprietary Information made pursuant to such governmental or judicial order
if it has complied with the provisions of this paragraph.

15.5 COMPENSATION: The Parties shall not be obligated to compensate each other
for the transfer of any Proprietary Information under this Agreement and agree
that no warranties of any kind are given with respect to such Proprietary
Information or any use thereof. No license is hereby granted under any patent,
trademark or copyrights with respect to any Proprietary Information.

15.6 SURVIVAL: The obligations of the Parties concerning confidentiality set
forth in this Article 15 shall survive termination or completion of this
Agreement. All documents, drawings and writings disclosing Proprietary
Information and all copies thereof shall be returned promptly by a party to the
other party upon receipt of a request therefor or following termination or
expiration of this Agreement except that recipient may keep one archival copy
for evidentiary purposes only.

unenforceable under any applicable law of any jurisdiction shall as to such
jurisdiction be ineffective without affecting any other provision of the
Agreement. To the full extent, however, that the provisions of such applicable

Note 1) Only one (1) order for an Accelerated lot can be accepted for processing
at any time from all Stanford Microdevices contracts.

Note 2) Accelerated lot pricing is only valid if wafers are shipped to Buyer not
later than 45 days from receipt of order or lot start, whichever is later. TRW
will deliver a minimum lot start. For a lot that is designated as Accelerated
after it has already started fabrication, the shipment date will be determined
as follows; 1+(1-EV) x 45 days from the time the lot is designated Accelerated
at TRW. EV equals the Earned Value or percent complete of the in-process lot.

Note 3) If the shipment date to Stanford Microdevices is 46 days or later (or as
defined above for a lot in process) from receipt of order or lot start, option
price shall not be charged. The option is available when ordered in conjunction
with a production lot or for a lot in process.

     [***]                [***]
</TABLE>

 Note 1) Only one (1) order for an Accelerated lot can be accepted for
 processing at any time from all Stanford Microdevices contracts.

 Note 2) Accelerated lot pricing is only valid if wafers are shipped to Buyer
 not later than 45 days from receipt of order or lot start, whichever is later.
 TRW will deliver a minimum of three (3) wafers for a six (6) wafer lot start.
 For a lot that is designated as Accelerated after it has already started
 fabrication, the shipment date will be determined as follows; 1+(l-EV) x 45
 days from the time the lot is designated Accelerated at TRW. EV equals the
 Earned Value or percent complete of the in-process lot.

 Note 3) If the shipment date to Stanford Microdevices is 46 days or later (or
 as defined above for a lot in process) from receipt of order or lot start,
 option price shall not be charged. The option is available when ordered in
 conjunction with a production lot or for a lot in process.

B.      MINIMUM QUANTITIES DURING CALENDAR YEAR 2000
The minimum purchase quantity of HBT wafers for the year 2000 shall be:

<TABLE>
<CAPTION>
             Product                    Number of Wafers

</TABLE>

If Buyer fails to purchase the minimum quantity, the price reverts to the
reversion price of [***] per wafer, TRW Darlington Amplifiers, and [***] per
wafer, SMD Circuits designed by Buyer. Prices are good and the order quantity is
measured for all deliveries starting 1 January 2000, no matter when they started
or when they were ordered. Releases against this delivery quantity will still be
by purchase order as it has been in 1999.
