each ASIC manufactured under this Agreement. 

  

	 	d.	Design Specifications (“Specifications”): This refers to the terms set forth in the Design Specifications Summary and in Buyer’s approved
post-layout simulation results based on final netlist. 

  
 2 

	 	e.	Register Transfer Language (“RTL”): A high-level description ASIC language provided by Buyer if the interface is “RTL Handoff.”

  

	 	f.	Timing Constraints: Chip input, chip output, and chip internal timing requirements, 

 

	 	g.	Synthesis: This process converts RTL to a netlist based on Seller’s ASIC components library. Synthesis is done by Seller since this is an RTL-Handoff.

  

	 	h.	Design Specifications Summary (Exhibit D): This document is used by Buyer to set forth the technical information necessary to define the manufacture of the final
Product. 

  

	 	i.	Floor Planning and Trial Place and Route Phase: Phase begins when Seller accepts or begins work on a partial or complete RTL. The RTL will be synthesized and the
synthesized netlist may be used to make and verify component placement information. Phase continues until Seller accepts or begins work on agreed-to final RTL. 

 

	 	j.	Approval to Start Final Place and Route Sheet: This document authorizes Seller to begin final place and/or route when the criteria in the document are met. The
execution of this form is a pre-requisite to start the final layout of the Product, 

  

	 	k.	Final Place and Route Phase: Phase begins with Seller’s acceptance of final RTL. 

 

	 	l.	Timing Data Extraction: Delay information pertaining to the ASIC, extracted from the layout. Final timing data extraction is the first one provided after Final
Place and Route Phase starts that meets the agreed to Timing Constraints set when entering the Final Place and Route Phase. 

  

	 	m.	Layout Data Verification: Seller verifies thai the ASIC obeys physical manufacturing rules and the layout functionally matches the Buyer’s circuit.

  

	 	n.	Post-Layout Approval Sheet: This document sets forth the post-layout output from the Seller’s design verification tools and allows Buyer and Seller to
indicate whether the data are acceptable and within the Buyer’s Specifications. The execution of this form is a prerequisite to tapeout and mask making for the Product and shall be deemed to incorporate Buyer’s Design Specifications
Summary and Buyer’s approved post-layout results. 

  

	 	o.	 Approval to Move to Mass Production: The Buyer must indicate approval in writing to move production control from Seller’s engineering to
Seller’s

 MANUFACTURING RIGHTS. 

 

	1.	Ariane grants to Enphase a [***], fully paid, non-exclusive. non-sublicensable (except to have made for Enphase) right and license to place orders for Product with, to
purchase Product from and receive delivery of Product directly from Ariane’s suppliers and to use, sell, import, export, offer for sale, or otherwise transfer Product using the Licensed Technology and manufacturing information supplied by
Ariane to its suppliers for the applicable Product. The right and license shall only be exercisable by Enphase if Ariane fails to deliver a Product to Enphase, because (a) Ariane files for bankruptcy protection under Chapter 7 or Chapter 11 of
the U.S. Bankruptcy Code or a receiver is appointed for Ariane and Ariane fails to deliver a Product to Enphase under this Agreement or a Purchase Order for a period of forty five (45) consecutive days after Enphase provides written notice of
such failure or (b) fails for any other reason whatsoever to deliver a Product to Enphase under this Agreement for a period of forty five (45) consecutive days after Enphase provides written notice of such failure. Failure to deliver means
failure to deliver the ordered quantities of acceptable Product within eight (8) weeks of the date of a Purchase Order. 

  

	2.	“Product” means Ariane’s PLM-1 ASIC. 

  

	3.	In the event that the conditions of Paragraph 1 have been satisfied and Ariane’s suppliers cease to manufacture Product, Ariane grants to Enphase a [***] fully
paid, non-exclusive, non-sublicensable (except to have made for Enphase) license to use the Licensed Technology for Product for the sole and limited purpose for Enphase to make, have made, use, sell, import, export, offer for sale, or otherwise
transfer Product. 

  

	4.	Ariane agrees that it will at all times keep Enphase apprised of the identity of its suppliers of Product until Enphase notifies Ariane that it no longer wishes to
purchase Product. Ariane agrees that it will notify each supplier of Product in writing of the existence of this Agreement with a copy to Enphase. 

  

	5.	The Parties agree that Ariane’s failure to notify its supplier that it has failed to deliver as that term is defined in Paragraph 1 would cause irreparable harm to
Enphase that cannot be adequately compensated at law. Accordingly, the parties agree that Enphase shall be entitled to seek injunctive relief requiring to Ariane or a receiver for Ariane to confirm in writing to Ariane’s supplier that a failure
to deliver has occurred.
