9. VERIFICATION

We or a certified auditor acting on Our behalf, may, upon Our reasonable request and at Our expense, audit You with respect to the use of the Software. Such audit may be conducted by mail, electronic means or through an in-person visit to Your place of business. Any such in-person audit shall be conducted during regular business hours at Your facilities and shall not unreasonably interfere with Your business activities. We shall not remove, copy, or redistribute any electronic material during the course of an audit. If an audit reveals that You are using the Software in a way that is in material violation of the terms of this Agreement, then You shall pay Our reasonable costs of conducting the audit. In the case of a material violation, You agree to pay Us any amounts owing that are attributable to the unauthorized use. In the alternative, We reserve the right, at Our discretion, to terminate the licenses for the Software, in addition to any other remedies available under law. This Section shall survive expiration or termination of this Agreement for a period of two (2) years.

10. PAYMENT AND TAXES

If credit has been extended to You by Us, all payments under this Agreement are due within thirty (30) days of the date We mail an invoice to You. If We have not extended credit to You, You shall be required to make payment concurrent with the delivery of the Software by Us. Any value added tax, use tax, sales tax or similar tax ("Transaction Taxes") shall be Your sole responsibility. Each party shall pay all taxes (including, but not limited to, taxes based upon its income) or levies imposed on it under applicable laws, regulations and tax treaties as a result of this Agreement and any payments made hereunder (including those required to be withheld or deducted from payments); provided that You shall be responsible for all Transactions Taxes and shall pay or reimburse Us for the same upon invoice. Each party shall furnish evidence of such paid taxes as is sufficient to enable the other party to obtain any credits available to it, including original withholding tax certificates. Notwithstanding the foregoing, Software ordered through Our resellers is subject to the fees and payment terms set forth on the applicable reseller invoice.

11. MISCELLANEOUS

The license granted herein applies only to the version of the Software available when purchased in connection with the terms of this Agreement, and to any updates and/or upgrades to which You may be entitled. Any previous or subsequent license granted to You for use of the Software shall be governed by the terms and conditions of the agreement entered in connection with purchase or download of that version of the Software. Support and maintenance, including rights to updates and upgrades, are provided pursuant to the terms of the DolphinDB Support and Maintenance Agreement. You agree that You will comply with all applicable laws and regulations with respect to the Software, including without limitation all export and re-export control laws and regulations.

While redistributing the DolphinDB Software or Modifications thereof as part of Your Application, You may choose to offer acceptance of support, warranty, indemnity, or other liability obligations and/or rights consistent with this Agreement. However, in accepting such obligations, You may act only on Your own behalf and on Your sole responsibility, not on our behalf. You shall indemnify Us and our resellers, or at Our option, defend Us and our resellers against any claim, suit or proceeding brought against Us or our resellers (i) arising by reason of Your accepting any such support, warranty, indemnity or additional liability; or (ii) arising out of the use, reproduction or distribution of Your Application, except to the extent such claim is solely based on the inclusion of the DolphinDB Software therein. Further, You agree only to distribute the DolphinDB Software pursuant to an enforceable written agreement for Our benefit that includes all the limitations and restrictions of this Agreement and is as protective of Us and DolphinDB Software as is this Agreement. For clarity, for DolphinDB Software for which You have paid a fee, You must purchase Designated User licenses for each contractor or consultant who uses the DolphinDB Software to create an Application on Your behalf (including system integrators), whether or not such contractor or consultant has its own license to the DolphinDB Software.

You agree to be identified as a customer of Ours and You agree that We may refer to You by name, trade name and trademark, if applicable, and may briefly describe Your business in our marketing materials and web site.

You may not assign or transfer this Agreement without Our prior written consent. Any attempted assignment or delegation in violation of this Section shall be null and void. This Agreement may be assigned by Us in whole or part and will inure to the benefit of Our successors and assigns. Notwithstanding the foregoing, in any instance in which You transfer ownership of an Application on a work for hire basis, You may assign licenses for the total Designated Users that have used the Software to develop said Application under this Agreement to another party (Assignee) provided (i) You provide written notice to Us prior to the effective date of such assignment; and (ii) the transfer is in quantities We generally make available to Our customers (minimum 5 Designated Users); and (iii) there is a written agreement, wherein the Assignee accepts the terms of this Agreement. Upon any such transfer, the Assignee may appoint new Designated Users.

This Agreement is the complete and exclusive statement of the mutual understanding of the parties and supersedes and cancels all previous written and oral agreements and communications relating to the subject matter of this Agreement. No oral or written information given by Us, Our resellers, or otherwise on Our behalf shall create a warranty or collateral contract, or in any way increase the scope of this Agreement in any way, and You may not rely on any such oral or written information. Any waivers or amendments shall be effective only if made in writing. Further, any different or additional terms of any related purchase order, confirmation, or similar form shall have no force or effect. The license granted herein is conditioned upon the acceptance of the terms and conditions hereof to the exclusion of all other terms, and no other or additional terms shall apply, unless so provided in writing signed by the parties hereto. You expressly agree by Your use of the Software that no such other, different or additional terms or conditions shall apply, notwithstanding any statements to the contrary included in any purchase order, confirmation, or similar form, and regardless of whether we accept payments referenced therein which shall not constitute acceptance of additional terms and conditions.

There are no implied licenses or other implied rights granted under this Agreement, and all rights, save for those expressly granted hereunder, shall remain with Us and our licensors. In addition, no licenses or immunities are granted to the combination of the Software and/or Modifications, as applicable, with any other software or hardware not delivered by Us or Our resellers to You under this Agreement. Your rights under this Agreement apply only to Software, Modifications, and/or Applications for which all Designated Users are duly licensed hereunder.

If any provision in this Agreement shall be determined to be invalid, such provision shall be deemed omitted; the remainder of this Agreement shall continue in full force and effect. If any remedy provided is determined to have failed for its essential purpose, all limitations of liability and exclusions of damages set forth in this Agreement shall remain in effect. The failure of either party to enforce any provision of this Agreement may not be deemed a waiver of that or any other provision of this Agreement.

This Agreement, and all claims or causes of action that may be based upon, arise out of, or relate to this Agreement and/or the Software shall be governed by the law of the State of California, United States (notwithstanding conflicts of laws provisions), and all parties irrevocably submit to the jurisdiction of the state or federal courts of the State of California and further agree to commence any litigation which may arise hereunder or related hereto and/or to the Software in the state or federal courts located in the judicial district of San Mateo County, California, US.

If the Software or any related documentation is licensed to the U.S. Government or any agency thereof, it will be considered to be "commercial computer software" or "commercial computer software documentation," as those terms are used in 48 CFR - 12.212 or 48 CFR 227.7202, and is being licensed with only those rights as are granted to all other licensees as set forth in this Agreement.
