本《<Super One车型面向量产工程服务协议>补充协议》（以下称“补充协议”）由以下双方：（1）GlobeX AI Hong Kong Holding Limited（“GX”），一家根据中国香港法律正式成立并存续的公司，地址为***（“合作伙伴”或“寰宙”），一家根据中国法律正式成立并存续的有限公司，其主要营业地位于***，于签署页最后签署日期（“生效日”）签订。

1.双方于2026年2月4日签署《Super One车型面向量产工程服务协议》及附件1《项目工作说明书》、附件2《Super One车型面向量产工程服务协议项下合作车型开发报价单》（以下统称“工程服务协议”，GX合同编号***，合作伙伴合同编号HZ-***），《知识产权主体授权确认函》（GX合同编号***）（上述文件统称“原协议”）。

The Parties entered into the Super One Model Mass Production-Oriented Engineering Services Agreement and its Appendix 1 Statement of Work for Program, Appendix 2 Quotation Agreement for Cooperative Model Development under Super One Model Mass Production-Oriented Engineering Services Agreement on February 4, 2026 (collectively referred to as the "Engineering Services Agreement", with GX contract number FFCN-***and Partner contract number ***), as well as the Intellectual Property Licensees Identity Confirmation Letter (GX contract number ***) (collectively referred to as the "Original Agreements").

The Parties intend to suspend the further performance of the Original Agreements from April 3, 2026(the “Suspension Date”), under the terms and conditions set forth herein, without prejudice to the rights and obligations accrued under the Original Agreements and the claims and debts existing prior to such suspension.

The Parties mutually agree that, as of the Suspension Date, all development, testing and engineering services under the Original Agreements (the specific scope and work shall be subject to the Statement of Work for Program) shall be fully suspended. During the suspension period of the Original Agreements, the Parties shall discontinue further performance of the development progress, milestone obligations and related cooperation matters under the Original Agreements.

1.2《知识产权主体授权确认函》项下双方的权利和义务同步暂停，保密义务除外。原协议暂停期间，合作伙伴暂停向确认函中GX及其指定关联方做出任何知识产权授权。双方确认，原协议暂停期间，原协议项下的技术开发活动已暂停，因此不产生新的背景知识产权和前景知识产权。原协议暂停期间，任何一方独立完成或与第三方合作完成的成果，其相关权利归该方独立享有，另一方对此不享有任何权利、许可或优先权。原协议暂停期间，合作伙伴已经授权GX使用的任何背景知识产权（如有），GX应自暂停日立即暂停使用。

The rights and obligations of the Parties under the Intellectual Property Licensees Identity Confirmation Letter shall also be suspended simultaneously, except for the confidentiality obligations. During the suspension period of the Original Agreements, the Partner shall suspend any intellectual property license to GX and its designated affiliates under the confirmation letter. The Parties confirm that, during the suspension period of the Original Agreements, technology development activities under the Original Agreements have been suspended, and therefore no new background intellectual property or foreground intellectual property will be generated. During the suspension period of the Original Agreements, any achievements independently completed by either Party or completed in cooperation with a third Party shall be owned solely by that Party, and the other Party shall have no rights, licenses or right of priority with respect thereto. During the suspension period of the Original Agreements, if any background intellectual property (if any) has been licensed by the Partner to GX,

1.3本补充协议项下的“暂停”系双方基于工程服务协议一致达成的安排。除本补充协议明确约定暂停或修改的内容外，原协议其余条款均应继续有效。特别地，原协议第4条独立承包商地位、分包商，5条保密信息，第10条期限、终止，第11条期满或终止的效力，第12条责任、补偿，第14条中为双方设定的义务不应暂停，双方应继续恪守执行。

The suspension under this Supplemental Agreement refers to an arrangement mutually agreed upon by the Parties based on the Engineering Services Agreement. Except for the matters expressly suspended or modified under this Supplemental Agreement, all other provisions of the Original Agreements shall remain in full force and effect. In particular, the following provisions under the Original Agreements shall not be suspended and the Parties shall continue to abide by and perform them: Section 4 (Independent Contractor Status, Subcontractors), Section 5 (Confidential Information), Section 10 (Term, Termination), Section 11 (Effect of Expiration or Termination), Section 12 (Liabilities, Indemnities), and the obligations imposed on both parties under Section 14.

1.4双方一致同意，截止暂停日GX已经支付的预付款3,100万人民币按照原协议附件2报价协议第3条约定做如下处理：3,100万人民币合作伙伴不予退还。GX确认该款项独立于本补充协议第1.5条项下的债务，不得进行任何形式的抵扣或对冲。GX确认在此不可撤销地放弃就该等款项向合作伙伴提出任何形式的追偿、返还、抵扣、重新计算或不当得利主张的权利。

The Parties mutually agree that the advance payment of CNY 31 million already made by GX as of the Suspension Date shall be handled in accordance with Section 3 of the Quotation Agreement (Appendix 2 to the Original Agreement) as follows: the CNY 31 million shall not be refunded by the Partner. GX confirms that such amount is independent of the debts under Section 1.5 of this Supplemental Agreement and shall not be subject to any form of deduction or set-off.. GX hereby irrevocably waives any right to claim recovery, refund, set-of, re-calculation or unjust enrichment against the Partner with respect to such amount.

1.5双方一致同意，截止暂停日，GX在原协议下已经到期应支付款项11,600万元人民币，实际支付3,100万元，到期应付未付款项共计人民币8,500.98万元（包括已到期未付本金8,500万元及利息9,800元，下称“到期未付款项”）。原协议的暂停履行不免除GX继续支付到期未付款项的义务。但合作伙伴同意，在原协议暂停履行期间，上述到期未付款项不再继续计收利息。

The Parties mutually agree that, as of the Suspension Date, the total amount due and payable by GX under the Original Agreement is CNY 116 million, of which CNY 31 million has been actually paid, and the overdue and unpaid amount is CNY 85,009,800 (including CNY 85 million in overdue principal and CNY 9,800 in interest, hereinafter referred to as the "Overdue Amount"). The suspension of the Original Agreement shall not relieve GX of its obligation to continue paying the Overdue Amount. However, the Partner agrees that, during the suspension period of the Original Agreement, no further interest shall accrue on the Overdue Amount.

1.6双方一致同意，自暂停日，因项目暂停，除本补充协议第1.5约定的款项外，项目暂停期间GX无需再向合作伙伴支付项目剩余款项50,400万元，且不计算其他相关费用。项目暂停期间，双方各自产生的费用由各自承担，任何一方不得向另一方主张索赔或补偿。

The Parties mutually agree that, as of the Suspension Date, due to the suspension of the project, GX shall not be required to pay the remaining project balance of CNY 504 million to the Partner during the suspension period, except for the amounts set forth in Section 1.5 of this Supplemental Agreement, and no other related fees shall be calculated. During the suspension period, any costs incurred by each Party shall be borne by such Party individually, and neither Party shall assert any claim or compensation against the other Party.

1.7双方一致同意，原协议暂停非因合作伙伴过错或过失造成。依据原协议约定，合作伙伴无需向GX交付任何有形或者无形交付物，亦无须向GX授权任何形式的知识产权许可。原协议暂停前已经完成内容，在原协议《项目工作说明书》内容不发生变化的情况下，若双方继续履行原协议，则不再重复计费。

Partner is not required to deliver any tangible or intangible deliverables to GX, nor is it required to grant any form of intellectual property license to GX. The completed work content prior to the suspension shall not be charged repeatedly when the Parties resume performance of the Original Agreement, provided that the content of the Statement of Work for Program under the Original Agreements does not change.

1.8双方一致同意，原协议暂停不免除、不抵销任何一方在暂停前的责任。暂停期间各自产生的任何损失均由各方自行承担，任何一方放弃就项目暂停期间自身产生的损失，放弃并免除向另一方主张任何形式的权利、索赔、请求、诉讼或追偿，但本补充协议1.1~1.7条中列明的除外情形不在此限。

The Parties mutually agree that the suspension of the Original Agreement shall not release or set-off any liability of either Party incurred prior to the suspension. Any losses incurred by each Party during the suspension period shall be borne solely by such Party. Each Party waives and releases the other Party from any rights, claims, demands, actions or recoveries of any kind arising from its own losses during the suspension period, except for the exclusions set forth in Section 1.1 to 1.7 of this Supplemental Agreement.

1.9双方一致同意，若GX拟继续原协议，应以结清本补充协议第1.5条约定的到期未付款项为先决条件，具体方案双方届时将另行协商。若双方继续原协议，合作伙伴有权根据届时的市场环境、技术标准变化、人力及物料成本波动等实际情况，调整原协议项下的相关里程碑节点。

The Parties mutually agree that if GX intends to resume the Original Agreement, the settlement of the Overdue Amount set forth in Section 1.5 of this Supplemental Agreement shall be a condition precedent. The specific plan shall be separately negotiated by the Parties at that time. If the Parties resume the Original Agreement, the Partner shall have the right to adjust the relevant milestone schedules under the Original Agreement based on the then-prevailing market environment, changes in technical standards, fluctuations in labor and material costs, and other actual circumstances.

4.1双方同意，本补充协议的内容以及与项目暂停相关的任何信息，均属保密信息。 “保密信息”是指由一方或代表一方（“披露方”）向另一方（“接收方”）提供的披露方及其关联方的所有非公开、保密或专有的信息和材料，包括但不限于任何上述各项的初稿、复制件、概要和摘录，和/或因本补充协议和/或与本补充协议有关而以其他方式产生的所有非公开、保密或专有的信息和材料，无论是口头披露的还是通过书面形式、电子形式或其他形式或媒体披露或获取的，也不论是否有该等标注，包括商业秘密。保密信息不包括以下任何信息：（1）非因接收方违反本补充协议而为或成为公众普遍可获得的信息（可识别个人身份的信息除外，该等信息应仍为保密信息）；（2）接收方在非保密的情况下从法律或合同未限制其披露该等信息的第三方处获得的信息；或（3）接收方有书面证据证实其在本补充协议项下披露日期之前就已合法占有的信息。双方进一步约定，本补充协议的条款和存在应被视为保密信息。双方确认，在本补充协议中，合作伙伴的保密信息应包含合作伙伴直接委托供应商的保密信息。

4.2受限使用。所有保密信息始终都是且仍是披露方的财产。接收方应将该等保密信息仅用于（在必要的范围内）履行其在本补充协议和任何适用的工作说明项下的义务。在披露方请求后或本补充协议终止后（以较早者为准），接收方应立即归还包含保密信息的所有文件和其他资料。但GX可保留已交付的交付物，GX仍应按本补充协议约定对交付物中包含的合作伙伴的保密信息（如有）承担保密义务。

Restricted Use. All Confidential Information is and shall remain the property of Disclosing Party at all times. Receiving Party shall use such Confidential Information only to the extent necessary to fulfill its obligations under this Supplemental Agreement and any applicable SOW.

4.3不披露。接收方和接收方代表同意并承认：其不享有保密信息的所有权，且不得向任何人或实体披露、传达或公布该等保密信息的性质或内容，也不得使用（经披露方书面授权的除外）其（或接收方的任何代表）从披露方处和/或因本补充协议而制作、接收、获取或获得的任何保密信息。接收方应采取（并促使接收方代表采取）所有必要措施，确保保密信息得到安全维护，包括促使所有接收方代表在经允许披露任何该等保密信息之前签署有关本协议所载保密信息的保密协议，其中条款的限制程度不低于本第4.3条中所载的限制性条款。如果接收方（或任何接收方代表）依法须披露任何保密信息，接收方应：(1)在适用法律允许的范围内，立即通知披露方任何此类披露要求；(2)采取披露方合理要求的措施以规避或限缩此类披露；以及 (3) 仅披露足以满足依法要求的最少量的保密信息。

4.4救济。接收方同意：任何违反或可能违反本第4条规定的情形不仅可能会给披露方造成经济损害，还可能会对其造成不可挽回的损害，而金钱赔偿将无法充分补偿损失。因此，除了本补充协议或适用法律项下规定的任何其他权利或救济以外，披露方还有权就任何可能违反或实际违反本第4条规定的情形向具有适当管辖权的任何法院寻求禁令性救济，而无需提供损失证明或担保。根据法律寻求任何救济不应被视为对救济的选择。

Remedies. Receiving Party agrees that any breach or threatened breach of this Section 4 could cause not only financial harm, but also irreparable harm, to Disclosing Party, and that money damages will not provide an adequate remedy. As such, in addition to any other rights or remedies provided hereunder or by applicable Law, Disclosing Party shall be entitled to seek injunctive relief in any court of law with appropriate jurisdiction for any threatened or actual breach of this Section 4, without proof of damages or the need to post security. Pursuit of any remedy at law shall not be deemed as an election of remedies.

Without the Partner's prior written consent, GX shall not, expressly or implicitly, use the name, logo, project content, or other information of the Partner's Directly Appointed Supplier for any commercial publicity, financing, or other public activities（Non-Partner's Directly Appointed Supplier shall be jointly confirmed by both Parties through weekly meetings; in urgent cases, both Parties shall confirm at any time as needed).
