For this purpose, LICENSEE may also modify, create derivative works, of and reproduce and have reproduced the Licensed Technology, and to develop, use, market and distribute (directly or through third parties) Licensed Technology, or modifications or derivative works of the Licensed Technology created by or for LICENSEE. (ii) In consideration for the right to modify, develop and completely own derivative works of the Licensed Technology set forth in Article 2.2 (i) above, LICENSEE shall pay D2 a license fee (the "Development License Fee") as set forth in Exhibit C. Final acceptance testing shall be completed by the parties according to Article 4 of this Agreement. (iii) LICENSEE shall pay D2 a license fee ("Runtime License Fee") as set forth in Exhibit C for each copy of the Licensed Technology that LICENSEE distributes to end users directly or through third parties for such end-user's use in connection with Licensee's Product. The Runtime License Fee shall be paid by LICENSEE quarterly for Licensee Products which have been paid for by Licensee's end-user customer in the prior quarter. To the extent Licensee accepts returns or is required to provide refunds to its customers (and to the extent additional Licensee Products are delivered to customers for warranty or maintenance/support purposes), such circumstances will either entitle Licensee to obtain a credit against future Runtime License Fees owed or, in the case of warranty/maintenance or support deliveries, no Runtime License Fees shall be due at all. (iv) LICENSEE is also granted a limited non-transferable non-exclusive license to Licensed Source Code to perform software maintenance functions according the terms set forth in Article 7 of this Agreement. (v) D2 shall provide LICENSEE with master copies of the Licensed Technology, in Source Code and Object Code format, promptly after such software has been completed, tested and approved for release by D2 and Licensee. In any event, D2 shall deliver all Licensed Technology completely tested and approved for performance in accordance with the specifications. 2.3 End User License.

Such additional technology licenses shall be subject to the same terms of this agreement except for an amendment to the product specification and price schedule of Exhibits A and C. Any other new licensing terms shall be negotiated in advance and included in said amendment. 3.2 Different Processors. (A) "Supported Processors": If D2 offers or plans to offer all or part of Licensed Technology on a processor ("Supported Processor") different from the Texas Instruments (TI) TMS320C54x family of processors, D2 shall make available to LICENSEE such new versions of Licensed Technology under the same terms of this Agreement subject to the license fees as follows: (i) The development license fees for any part or all of Licensed Technology for each "Supported Processor" shall be 50% of that for the TMS320C54x processor family as listed in Exhibit C. (ii) The per-processor runtime license fees for any "Supported Processor" shall be the same as that specified in Exhibit C for the TI TMS320C54x.
