1.4 “House Accounts” shall mean those Customers in the Territory who purchase Products directly from AOS. House Accounts
designated by AOS at the time of execution of this Agreement are set forth on Exhibit B attached hereto, which may be amended or updated by AOS from time to time at its sole discretion.

or otherwise to be modified as requested by the Distributor and approved by AOS in writing. 

 1.6 “Proprietary Rights” shall mean all rights in the Products and
AOS’s Confidential Information, including, but not limited to, patents, copyrights, trademarks, trade names, know-how, show-how, and trade secrets, irrespective of whether such rights arise under U.S. or international intellectual property,

the Distributor; the Products shall include DSSL Products and Non-standard Products set forth in Exhibit A, which shall be amended or updated by AOS from time to time. 

1.8 “Territory” shall mean the geographic area of Asia. 

2. APPOINTMENT 
 2.1
Appointment of Nonexclusive Distributor. Subject to the terms and conditions of this Agreement, AOS appoints the Distributor, and the Distributor hereby accepts such appointment, as AOS’S non-exclusive authorized distributor for sale of
the Products to the Customers (other than House Account) in the Territory (as these terms are defined in Section 1.8, above). 

2.2 Designation of House Account. In the event AOS notifies the Distributor that AOS has designated a Customer of the Distributor
as a new House Account, such Customer will become a House Account effective Ninety (90) days following such notice. At AOS’s sole discretion, AOS may compensate the Distributor for extraordinary sales and distribution efforts rendered
prior to the designation of the new House Account. 
 3. DISTRIBUTOR RESPONSIBILITIES 

3.1 Market Promotion. The Distributor shall use its best efforts, consistent with prudent business practice, and shall devote such
time as may be commercially reasonably necessary, to conduct an aggressive marketing and selling program and to promote the sale of the Products. 

3.2 No Product Change. The Distributor shall not modify or change the Products in any way without the express prior written
consent of AOS. 
 3.3 Conflict of Interest. The Distributor shall not, during the term of this Agreement, directly or
indirectly market, sell, distribute, solicit orders within the Territory for any products which are competitive with the Products unless AOS consents thereto in writing in advance, based upon the Distributor’s full disclosure of the material
facts in seeking such consent. Any such marketing, sale, distribution or solicitation of the competitive products is considered to be a material breach of this Agreement. 

3.4 Reports. Distributor shall submit periodical reports according to Exhibit C. 

3.5 Compliance with Laws. The Distributor shall comply at its own expense with all applicable laws and regulations currently
existing in the Territory relating to the sale, distribution and promotion of the Products. Distributor shall not export, directly or indirectly, any Products or related information without first obtaining all required licenses and approvals from
the appropriate government agencies. 
  

 2 

 3.6 Feedbacks. The Distributor shall provide AOS with prompt written notification of
any comments or complaints about the Products that are made by Customers, and of any problems with the Products or their use that the Distributor becomes aware of. Such written notification shall be the property of AOS, and shall be considered to be
part of AOS’s Confidential Information. 
 3.7 Referral. The Distributor agrees to refer all prospective customers
to AOS when the Distributor cannot aggressively pursue distribution to such customers because of geographic location or any other reason; if the Distributor cannot aggressively pursue distribution because of price and/or volume, the parties will
negotiate a reasonable referral fee to be mutually agreed upon. The Distributor shall also refer directly to AOS inquiries relating to bundling, partnership or other business opportunities with third party vendors, hardware and system manufacturers
and software developers. 
 3.8 Inventory. The Distributor shall maintain an inventory of Products in reasonably
sufficient quantities to provide adequate and timely delivery to the Customers. At a minimum, such inventory shall include not less than the quantity of Products necessary to meet Distributor’s reasonably anticipated demands for a thirty
(30) day period. 
 3.9 Audits. AOS shall be entitled at any time to audit the Distributor’s books and records
upon reasonable notice in order to confirm the accuracy of the Reports set forth in Section 3.4; provided, that no more than one such audit may be conducted in any three-month period. Any AOS-elected audit shall be performed at AOS’s own
expense during normal business hours; Distributor shall provide reasonable assistance to AOS for the audit. Additionally, the Distributor shall provide AOS with its audited financial statements within three (3) months of the end of its fiscal
year. 
 4. ORDERS AND ACCEPTANCE 

4.1 Rolling Forecast. The Distributor shall provide AOS at least one month in advance with a good faith rolling quarterly sales
forecast for the units of the Products to be provided by AOS to the Distributor hereunder during each month in such calendar quarter. 

4.2 Purchase Orders. The Distributor shall initiate purchases under this Agreement by submitting written purchase orders (each, an
“Order”) to AOS. Such orders shall state unit quantities, unit descriptions, requested delivery dates, and shipping instructions. No purchase order shall be binding upon AOS until accepted by AOS in writing. AOS reserves the right
to reject orders in whole or in part. Partial shipment of an order shall not constitute acceptance of the entire order. In the event that AOS is unable to fill an accepted purchase order in accordance with the schedule set forth therein, AOS will
use commercially reasonable efforts to fill such order on an allotment basis. This Agreement shall govern all orders placed by the Distributor for units of the Product. No terms on purchase orders, invoices or like documents produced by the
Distributor shall alter or add to the terms of this Agreement. Any other terms and conditions of sale in conflict with or inconsistent with the terms and conditions of this Agreement, whether contained in the Distributor’s preprinted forms or
otherwise, notwithstanding AOS’s acceptance otherwise, shall have no force or effect to the extent of such conflict or inconsistency. 
  

 3 

 4.3 Order Requirements. The Distributor’s single purchase order amount shall be
in multiples of the unit quantity calculated in numbers of cartons according to specifications of AOS set forth in Exhibit A. Orders for less than unit quantity multiples will be increased without prior notice to the next larger multiple.
Non-standard Products may have higher minimum purchase requirements as determined by AOS. 
 4.4 Lead Time. The
Distributor shall submit purchase orders to AOS in accordance with a lead time of twenty-eight (28) to one hundred and twenty (120) days according to the schedule advised by AOS. In no event shall the lead time for Non-standard Products be
less than two (2) months. AOS shall use commercially reasonable efforts to deliver units of Product at the times set forth in AOS’s written acceptances of the Distributor’s purchase orders. 

4.5 Demonstration Units. Orders by Distributor for samples and/or pilot run may be subject to smaller amount and shorter cycle
time as shall be requested by Distributor and accepted by AOS. In such cases, products may be ordered in multiples of smaller units (calculated in number of reels or tubes), and in no events shall exceed three such units. 

4.6 Cancellations. Except as provided herein, all Orders for Products are non-cancelable and Products are non-returnable (NC/NR).
Subject to AOS’s written approval, orders for DSSL Products may be rescheduled or cancelled subject to the cancellation fees, which are based on the number of days in advance of the scheduled shipment date that the Distributor notifies AOS of
cancellation. The Nonstandard Products are at all times non-cancelable. Distributor shall contact AOS in advance for pricing and delivery information for orders of Non-standard Products. 

5. PRICES; PRICE CHANGES; SPECIAL PRICING 

5.1 AOS Price. Subject to the terms and conditions of this Agreement, the Distributor shall pay for the Products at the then
current price of AOS (the “AOS Price”) at the time of placement of the Order. 
 5.2 Price Change. AOS
shall have the right to revise AOS Price at any time. Price changes shall apply to all purchase orders received after the effective date with the notice, except that any price increase shall be effective immediately upon notice to Distributor and
apply to those accepted but undelivered orders. 
 5.3 Special Pricing. Notwithstanding the AOS Price, special pricing on
any one of the Products may be extended to the Distributor, in AOS sole discretion, in situations where special pricing is necessary for the Distributor to obtain sale of the Products to a Customer. If AOS elects to extend such special pricing, it
will issue a confidential meet comp quote number documenting the special price quoted. Upon receipt of the meet comp quote number, the Distributor may ship the Products to the Customer from stock and debit AOS for the difference between their
invoiced amount, less any prior credits granted by AOS, and the new special pricing. The meet comp quote number shall be included on all such debits. 

5.4 Taxes. All AOS Prices are exclusive of any export, withholding, federal, state and local taxes, duties or excises other than
taxes based on AOS’s net income. If AOS pays any taxes, duties or excises which are not included in the fees charged for the Product, AOS shall itemize such taxes, duties or excises as a separate item on its invoices to the Distributor, and the
Distributor shall reimburse AOS for such taxes, duties or excises; provided, that the Distributor shall not be required to make any such reimbursement if it provides a valid tax exemption certificate to AOS prior to shipment. 

 

 4 

 6. TERMS OF PAYMENT 

6.1 Payment Terms. AOS shall submit an invoice to the Distributor upon shipment of Products to the Distributor. The invoice shall
state the amount to be paid by the Distributor for all Products in such shipment, as well as any taxes, duties or excises paid by AOS which shall be reimbursed by the Distributor in accordance with Section 5.4. Terms of payment shall be net
thirty (30) days. All payments shall be in U.S. Dollars. 
 6.2 Late Payments. All amounts which are not timely paid
by the Distributor as required by this Agreement shall be subject to a late charge equal to one and one-half percent (1.5%) per month (or, if less, the maximum allowed by applicable law). In the event that any payment due hereunder is overdue,
AOS reserves the right to suspend performance until such delinquency is corrected. 
 7. DELIVERY 

7.1 Packing and Shipping. All Products to the Distributor shall be packaged in AOS’s standard containers, or, at the
Distributor’s expense, in accordance with instructions provided by the Distributor, and shall be shipped to the Distributor’s address set forth above, or to an address specified in the purchase order. Unless otherwise agreed, shipment
shall conform to AOS’s standard shipping procedures CFR Hong Kong (“Delivery Point”), or such terms as both shall agree. Title and risk of loss shall pass to the Distributor at the Delivery Point. All customs duties, freight,
insurance and other shipping expenses from the Delivery Point, as well as any other special packing expenses requested by the Distributor, shall be borne by the Distributor. The Distributor agrees to satisfy all import formalities pertaining to
shipment of units of the Product to destinations outside the United States. 
 7.2 Inspection and Acceptance. The
Distributor shall have thirty (30) days (the “Inspection Period”) upon receipt of each shipment to inspect and test the Products. If the Distributor determines any unit of Products defective, the Distributor shall promptly
notify AOS of such defects. Defective Products may be returned for retest, evaluation and examination subject to AOS Returned Material Authorization (“RMA”) procedure; provided, that such written notification and request for an RMA
number must be received by AOS during the Inspection Period. Returns must be prepaid by Distributor. When requesting a return authorization, Distributor must supply Distributor’s purchase order number and AOS’s invoice number. Product
description must include lot number and wafer numbers. 
 7.3 Exclusion. AOS will inspect all Products returned pursuant
to the foregoing RMA procedures, and AOS will not replace products where the defect is due to misuse, neglect, alteration or improper storage by the Distributor.

WHEREAS, Distributor has been, and desires to continue to be, a nonexclusive distributor of AOS for certain power semiconductor products;
AOS wishes to sell its products through Distributor on a continuing basis on the terms and conditions set forth below. 

AGREEMENT 

NOW, THEREFORE, in consideration of the mutual agreements and covenants, AOS and the Distributor agree as follows: 

1. DEFINITIONS 
 1.1
“Confidential Information” of a party shall mean any information disclosed by that party to the other party pursuant to this Agreement which is in written, graphic, machine readable or other tangible form and is marked
“Confidential,” “Proprietary” or in some other manner to indicate its confidential nature. Confidential Information may also include oral information disclosed by one party to the other pursuant to this Agreement, provided that
such information is designated as confidential at the time of disclosure and is reduced to writing by the disclosing party within a reasonable time (not to exceed thirty (30) days) after its oral disclosure, and such writing is marked in a
manner to indicate its confidential nature and delivered to the receiving party. 
 1.2 “Customers” shall mean
the purchasers of the Products whose principal offices and operations are located in the Territory. 
 1.3 “DSSL
Products” shall mean those Products according to the Distributor Standard Stock List or “DSSL”, as AOS and the Distributor shall maintain and modify from time to time. 

1.4 “House Accounts” shall mean those Customers in the Territory who purchase Products directly from AOS. House Accounts
designated by AOS at the time of execution of this Agreement are set forth on Exhibit B attached hereto, which may be amended or updated by AOS from time to time at its sole discretion. 

1.5 “Non-standard Products” shall mean those Products not referenced in the DSSL that require special testing, packaging
or otherwise to be modified as requested by the Distributor and approved by AOS in writing. 

 1.6 “Proprietary Rights” shall mean all rights in the Products and
AOS’s Confidential Information, including, but not limited to, patents, copyrights, trademarks, trade names, know-how, show-how, and trade secrets, irrespective of whether such rights arise under U.S. or international intellectual property,
unfair competition or trade secret laws. 
 1.7 “Products” shall mean the products offered by AOS for sale to
the Distributor; the Products shall include DSSL Products and Non-standard Products set forth in Exhibit A, which shall be amended or updated by AOS from time to time. 

1.8 “Territory” shall mean the geographic area of Asia. 

2. APPOINTMENT 
 2.1
Appointment of Nonexclusive Distributor. Subject to the terms and conditions of this Agreement, AOS appoints the Distributor, and the Distributor hereby accepts such appointment, as AOS’S non-exclusive authorized distributor for sale of
the Products to the Customers (other than House Account) in the Territory (as these terms are defined in Section 1.8, above). 

2.2 Designation of House Account. In the event AOS notifies the Distributor that AOS has designated a Customer of the Distributor
as a new House Account, such Customer will become a House Account effective Ninety (90) days following such notice. At AOS’s sole discretion, AOS may compensate the Distributor for extraordinary sales and distribution efforts rendered
prior to the designation of the new House Account. 
 3. DISTRIBUTOR RESPONSIBILITIES 

3.1 Market Promotion. The Distributor shall use its best efforts, consistent with prudent business practice, and shall devote such
time as may be commercially reasonably necessary, to conduct an aggressive marketing and selling program and to promote the sale of the Products. 

3.2 No Product Change. The Distributor shall not modify or change the Products in any way without the express prior written
consent of AOS. 
 3.3 Conflict of Interest. The Distributor shall not, during the term of this Agreement, directly or
indirectly market, sell, distribute, solicit orders within the Territory for any products which are competitive with the Products unless AOS consents thereto in writing in advance, based upon the Distributor’s full disclosure of the material
facts in seeking such consent. Any such marketing, sale, distribution or solicitation of the competitive products is considered to be a material breach of this Agreement. 

3.4 Reports. Distributor shall submit periodical reports according to Exhibit C. 

3.5 Compliance with Laws. The Distributor shall comply at its own expense with all applicable laws and regulations currently
existing in the Territory relating to the sale, distribution and promotion of the Products. Distributor shall not export, directly or indirectly, any Products or related information without first obtaining all required licenses and approvals from
the appropriate government agencies. 
  

 2 

 3.6 Feedbacks. The Distributor shall provide AOS with prompt written notification of
any comments or complaints about the Products that are made by Customers, and of any problems with the Products or their use that the Distributor becomes aware of. Such written notification shall be the property of AOS, and shall be considered to be
part of AOS’s Confidential Information. 
 3.7 Referral. The Distributor agrees to refer all prospective customers
to AOS when the Distributor cannot aggressively pursue distribution to such customers because of geographic location or any other reason; if the Distributor cannot aggressively pursue distribution because of price and/or volume, the parties will
negotiate a reasonable referral fee to be mutually agreed upon. The Distributor shall also refer directly to AOS inquiries relating to bundling, partnership or other business opportunities with third party vendors, hardware and system manufacturers
and software developers. 
 3.8 Inventory. The Distributor shall maintain an inventory of Products in reasonably
sufficient quantities to provide adequate and timely delivery to the Customers. At a minimum, such inventory shall include not less than the quantity of Products necessary to meet Distributor’s reasonably anticipated demands for a thirty
(30) day period. 
 3.9 Audits. AOS shall be entitled at any time to audit the Distributor’s books and records
upon reasonable notice in order to confirm the accuracy of the Reports set forth in Section 3.4; provided, that no more than one such audit may be conducted in any three-month period. Any AOS-elected audit shall be performed at AOS’s own
expense during normal business hours; Distributor shall provide reasonable assistance to AOS for the audit. Additionally, the Distributor shall provide AOS with its audited financial statements within three (3) months of the end of its fiscal
year. 
 4. ORDERS AND ACCEPTANCE 

4.1 Rolling Forecast. The Distributor shall provide AOS at least one month in advance with a good faith rolling quarterly sales
forecast for the units of the Products to be provided by AOS to the Distributor hereunder during each month in such calendar quarter. 

4.2 Purchase Orders. The Distributor shall initiate purchases under this Agreement by submitting written purchase orders (each, an
“Order”) to AOS. Such orders shall state unit quantities, unit descriptions, requested delivery dates, and shipping instructions. No purchase order shall be binding upon AOS until accepted by AOS in writing. AOS reserves the right
to reject orders in whole or in part. Partial shipment of an order shall not constitute acceptance of the entire order. In the event that AOS is unable to fill an accepted purchase order in accordance with the schedule set forth therein, AOS will
use commercially reasonable efforts to fill such order on an allotment basis. This Agreement shall govern all orders placed by the Distributor for units of the Product. No terms on purchase orders, invoices or like documents produced by the
Distributor shall alter or add to the terms of this Agreement. Any other terms and conditions of sale in conflict with or inconsistent with the terms and conditions of this Agreement, whether contained in the Distributor’s preprinted forms or
otherwise, notwithstanding AOS’s acceptance otherwise, shall have no force or effect to the extent of such conflict or inconsistency. 
  

 3 

 4.3 Order Requirements. The Distributor’s single purchase order amount shall be
in multiples of the unit quantity calculated in numbers of cartons according to specifications of AOS set forth in Exhibit A. Orders for less than unit quantity multiples will be increased without prior notice to the next larger multiple.
Non-standard Products may have higher minimum purchase requirements as determined by AOS. 
 4.4 Lead Time. The
Distributor shall submit purchase orders to AOS in accordance with a lead time of twenty-eight (28) to one hundred and twenty (120) days according to the schedule advised by AOS. In no event shall the lead time for Non-standard Products be
less than two (2) months. AOS shall use commercially reasonable efforts to deliver units of Product at the times set forth in AOS’s written acceptances of the Distributor’s purchase orders. 

4.5 Demonstration Units. Orders by Distributor for samples and/or pilot run may be subject to smaller amount and shorter cycle
time as shall be requested by Distributor and accepted by AOS. In such cases, products may be ordered in multiples of smaller units (calculated in number of reels or tubes), and in no events shall exceed three such units. 

5. PRICES; PRICE CHANGES; SPECIAL PRICING 

5.1 AOS Price. Subject to the terms and conditions of this Agreement, the Distributor shall pay for the Products at the then
current price of AOS (the “AOS Price”) at the time of placement of the Order. 
 5.2 Price Change. AOS
shall have the right to revise AOS Price at any time. Price changes shall apply to all purchase orders received after the effective date with the notice, except that any price increase shall be effective immediately upon notice to Distributor and
apply to those accepted but undelivered orders. 
 5.3 Special Pricing. Notwithstanding the AOS Price, special pricing on
any one of the Products may be extended to the Distributor, in AOS sole discretion, in situations where special pricing is necessary for the Distributor to obtain sale of the Products to a Customer. If AOS elects to extend such special pricing, it
will issue a confidential meet comp quote number documenting the special price quoted. Upon receipt of the meet comp quote number, the Distributor may ship the Products to the Customer from stock and debit AOS for the difference between their
invoiced amount, less any prior credits granted by AOS, and the new special pricing. The meet comp quote number shall be included on all such debits. 

5.4 Taxes. All AOS Prices are exclusive of any export, withholding, federal, state and local taxes, duties or excises other than
taxes based on AOS’s net income. If AOS pays any taxes, duties or excises which are not included in the fees charged for the Product, AOS shall itemize such taxes, duties or excises as a separate item on its invoices to the Distributor, and the
Distributor shall reimburse AOS for such taxes, duties or excises; provided, that the Distributor shall not be required to make any such reimbursement if it provides a valid tax exemption certificate to AOS prior to shipment. 

 

 4 

 6. TERMS OF PAYMENT 

6.1 Payment Terms. AOS shall submit an invoice to the Distributor upon shipment of Products to the Distributor. The invoice shall
state the amount to be paid by the Distributor for all Products in such shipment, as well as any taxes, duties or excises paid by AOS which shall be reimbursed by the Distributor in accordance with Section 5.4. Terms of payment shall be net
thirty (30) days. All payments shall be in U.S. Dollars. 
 7. DELIVERY 

7.1 Packing and Shipping. All Products to the Distributor shall be packaged in AOS’s standard containers, or, at the
Distributor’s expense, in accordance with instructions provided by the Distributor, and shall be shipped to the Distributor’s address set forth above, or to an address specified in the purchase order. Unless otherwise agreed, shipment
shall conform to AOS’s standard shipping procedures CFR Hong Kong (“Delivery Point”), or such terms as both shall agree. Title and risk of loss shall pass to the Distributor at the Delivery Point. All customs duties, freight,
insurance and other shipping expenses from the Delivery Point, as well as any other special packing expenses requested by the Distributor, shall be borne by the Distributor. The Distributor agrees to satisfy all import formalities pertaining to
shipment of units of the Product to destinations outside the United States. 
 7.2 Inspection and Acceptance. The
Distributor shall have thirty (30) days (the “Inspection Period”) upon receipt of each shipment to inspect and test the Products. If the Distributor determines any unit of Products defective, the Distributor shall promptly
notify AOS of such defects. Defective Products may be returned for retest, evaluation and examination subject to AOS Returned Material Authorization (“RMA”) procedure; provided, that such written notification and request for an RMA
number must be received by AOS during the Inspection Period. Returns must be prepaid by Distributor. When requesting a return authorization, Distributor must supply Distributor’s purchase order number and AOS’s invoice number. Product
description must include lot number and wafer numbers. 
 7.3 Exclusion. AOS will inspect all Products returned pursuant
to the foregoing RMA procedures, and AOS will not replace products where the defect is due to misuse, neglect, alteration or improper storage by the Distributor.

Agreement for any reason, such authorization will cease.

through any person or entity, in any form or manner, copy, distribute, reproduce, incorporate, use or allow access to the Products or modify, prepare derivative works of, decompile, reverse engineer, disassemble or otherwise attempt to derive source

8.3 Proprietary Notice. The Distributor will ensure that all copies of the Products will incorporate copyright and other
proprietary notices in the same manner that AOS incorporates such notices in the Products or in any manner reasonably requested by AOS. The Distributor will not remove any copyright or other proprietary notices incorporated on or in the Products by

“AOS Trademarks”). AOS shall provide the Distributor AOS Trademarks on disk or camera-ready art for production. The Distributor understands that AOS has applied for applicable federal and state registration of certain of its
trademarks and agrees, upon AOS’s request, to so indicate on the box containing the Products and in any advertisement, promotional materials or other documents that contain the Products’ names. Nothing herein will grant to the Distributor
any right, title or interest in AOS Trademarks. At no time during or after the term of this Agreement will the Distributor challenge or assist others to challenge AOS Trademarks or the registration thereof or attempt to register any trademarks,

intellectual property rights claimed by AOS in such trademarks.

defaulting party that if the default is not cured within thirty (30) days the Agreement will be terminated. If the non-defaulting party gives such notice and the default is not cured during the thirty (30) day period, then the Agreement

assistance, will be subject in all respects to such United States laws and regulations and will from time to time govern the license and delivery of technology and products abroad by persons subject to the jurisdiction of the United States,
including the Export Administration Act of 1979, as amended, any successor legislation, and the Export Administration Regulations issued by the Department of Commerce, International Trade Administration, or Office of Export Licensing. Distributor
warrants that it will comply in all respects with the export and re-export restrictions for all Products shipped to Distributor. Distributor will take all actions which may be reasonably necessary to assure that no end-user contravenes such United
States laws or regulations. 
 15.8 Force Majeure. In the event that either party is prevented from performing or is
unable to perform any of its obligations under this Agreement (other than a payment obligation) due to any Act of God, fire, casualty, flood, earthquake, war, strike, lockout, epidemic, destruction of production facilities, riot, insurrection,
material unavailability, or any other cause beyond the reasonable control of the party invoking this section, and if such party shall have used its best efforts to mitigate its effects, such party shall give prompt written notice to the other party,
its performance shall be excused, and the time for the performance shall be extended for the period of delay or inability to perform due to such occurrences. Notwithstanding the foregoing, if such party is not able to perform within thirty
(30) days after the event giving rise to the excuse of force majeure, the other party may terminate this Agreement. 
 15.9
Severability. If one or more provisions of this Agreement are held to be unenforceable under applicable law, the parties agree to renegotiate such provision in good faith, in order to maintain the economic position enjoyed by each party as
close as possible to that under the provision rendered unenforceable. In the event that the parties cannot reach a mutually agreeable and enforceable replacement for such provision, then (i) such provision shall be excluded from this Agreement,
(ii) the balance of the Agreement shall be interpreted as if such provision were so excluded and (iii) the balance of the Agreement shall be enforceable in accordance with its terms. 

15.10 Titles and Subtitles. The titles and subtitles used in this Agreement are used for convenience only and are not to be

 15.11 Choice of Law; Dispute Resolution. This Agreement shall
be governed by and construed pursuant to the laws of the State of California, U.S.A., without reference to principals of conflicts of laws. All disputes arising out of this shall be settled by final binding arbitration in Santa Clara County,
California, pursuant to the Commercial Arbitration Rules of the American Arbitration Association. Judgment on the award rendered by the arbitrators may be entered in any court having competent jurisdiction thereof. Notwithstanding the foregoing, the
parties may apply to any court of competent jurisdiction in Santa Clara County, California, U.S.A., for a temporary restraining order, preliminary injunction, or other interim or conservatory relief, as necessary, without breach of this arbitration
agreement and without any abridgment of the powers of the arbitrators, and agree that such courts shall have exclusive jurisdiction of any such action.
