The requesting Party shall bear all costs and expenses in connection therewith.

Section 4.6 Confidentiality. Each of the Parties shall hold and shall cause each of their respective subsidiaries and VIE(s) to hold, and shall each cause their respective officers, employees, agents, consultants and advisors and those of their respective subsidiaries and VIE(s) to hold, in strict confidence and not to disclose or release without the prior written consent of the other Party, any and all Confidential Information concerning such other Party and its respective subsidiaries and VIE(s); provided, that each of the Parties may disclose, or may permit disclosure of, Confidential Information (i) to their respective subsidiaries and VIE(s), auditors, attorneys, financial advisors, bankers and other appropriate consultants and advisors who have a need to know such information and, in each case, are informed of their obligation to hold such information confidential to the same extent as is applicable to the Parties hereto and in respect of whose failure to comply with such obligations, Weibo or SINA, as the case may be, will be responsible, (ii) if the Parties or any of their respective subsidiaries or VIE(s) are compelled to disclose any such Confidential Information by judicial or administrative process or (iii) if the Parties reasonably determine in good faith that such disclosure is required by other requirements of law. Notwithstanding the foregoing, in the event that any demand or request for disclosure of Confidential Information is made in connection with any judicial or administrative process, or a Party determines in good faith that disclosure is otherwise required by law, such Party shall promptly notify the other Party of the existence of such request, demand, or conclusion, and shall provide such other Party a reasonable opportunity to seek an appropriate protective order or other remedy, which the notifying Party will cooperate in obtaining.

(i) “Confidential Information” shall mean Confidential Business Information and Confidential Technical Information concerning one Party which, prior to, on or following the Public Filing Date, has been disclosed by such Party or its subsidiaries or VIE(s), that (1) is in written, recorded, graphical or other tangible form and is marked “Proprietary,” “Confidential” or “Trade Secret,” or where it is evident from the nature and content of such Information that the disclosing Party considers it to be confidential, (2) is in oral form and identified by the disclosing Party as “Proprietary”, “Confidential” or “Trade Secret” at the time of oral disclosure, including pursuant to the access provisions of Section 4.3 or Section 4.5 hereof or any other provision of this Agreement or where it is evident from the nature and content of such Information that the disclosing Party considers it to be confidential, or (3) in the case of such Information disclosed on or prior to the date hereof, either such Information is identified by the owning Party to the other relevant Party as Confidential Business Information or Confidential Technical Information, orally or in writing on or prior to the Public Filing Date, or it is evident from the nature and content of such Information that the disclosing Party considers it to be confidential, and includes any modifications or derivatives prepared by the receiving Party that contain or are based upon any Confidential Information obtained from the disclosing Party, including any analysis, reports, or summaries of the Confidential Information. Confidential Information may also include Information disclosed to a disclosing Party by third parties. Confidential Information shall not, however, include any information which (A) was publicly known and made generally available in the public domain prior to the time of disclosure by the disclosing Party; (B) becomes publicly known and made generally available after disclosure by the disclosing Party to the receiving Party through no action or inaction of the receiving Party; (C) is obtained by the receiving Party from a third party without a breach of such third party’s obligations of confidentiality; or (D) is on or after the Public Filing Date independently developed by the receiving Party without use of or reference to the disclosing Party’s Confidential Information.

Moreover, nothing in the Agreement supersedes any restriction imposed by third parties on their Confidential Information, and there is no obligation on the disclosing Party to conform third party agreements to the terms of this Agreement except as expressly set forth therein.

(d) Notwithstanding anything to the contrary set forth herein, (i) a Party and its subsidiaries and VIE(s) shall be deemed to have satisfied their obligations hereunder with respect to Confidential Information if they exercise the same degree of care (but no less than a reasonable degree of care) as they take to preserve confidentiality for their own similar Information and (ii) confidentiality obligations provided for in any agreement between a Party or any of its subsidiaries or VIE(s) and any employee of such Party or any of its subsidiaries or VIE(s) shall remain in full force and effect.

(e) Confidential Information of a Party and its subsidiaries and VIE(s) in the possession of and used by the other Party as of the Public Filing Date may continue to be used by such Party in possession of the Confidential Information in and only in the operation of the SINA Business, in the case of SINA and its subsidiaries and VIEs, or the Weibo Business, in the case of Weibo and its subsidiaries and VIE, and may be used only so long as the Confidential Information is maintained in confidence and not disclosed in violation of Section 4.6(b). Such continued right to use Confidential Information may not be transferred, including by merger, consolidation, reorganization, operation of law, or otherwise, to any third party unless such third party (A) purchases all or substantially all of the business or business line and assets in one transaction or in a series of related transactions for which or in which the relevant Confidential Information is used or employed and (B) expressly agrees in writing to be bound by the provisions of this Section 4.6. In the event that such right to use is transferred in accordance with the preceding sentence, the transferring Party shall not disclose the source of the relevant Confidential Information.

The Parties agree that their respective rights and obligations to maintain, preserve, assert or waive any or all privileges belonging to each such Party or its subsidiaries or VIE(s) including but not limited to the attorney-client and work product privileges (collectively, “Privileges”), shall be governed by the provisions of this Section 4.7. With respect to Privileged Information (as defined below) of SINA, SINA shall have sole authority in perpetuity to determine whether to assert or waive any or all Privileges, and Weibo shall take no action (nor permit any of its subsidiaries or VIE(s) to take action) without the prior written consent of SINA that could result in any waiver of any Privilege that could be asserted by SINA or any of its subsidiaries or VIEs under applicable law and this Agreement. With respect to Privileged Information of Weibo, Weibo shall have sole authority in perpetuity to determine whether to assert or waive any or all Privileges, and SINA shall take no action (nor permit any of its subsidiaries or VIEs to take action) without the prior written consent of Weibo that could result in any waiver of any Privilege that could be asserted by Weibo or any of its subsidiaries or VIE under applicable law and this Agreement.

(a) The rights and obligations created by this Section 4.7 shall apply to all Information as to which the Parties or their respective subsidiaries or VIE(s) would be entitled to assert or has asserted a Privilege (“Privileged Information”).

Privileged Information of Weibo includes but is not limited to (x) any and all Information regarding the Weibo Business, whether or not it is in the possession of SINA or any of its subsidiaries and VIEs; (y) all communications subject to a Privilege occurring after the Public Filing Date between counsel for Weibo (including in-house counsel and former in-house counsel who are or were employees of SINA) and any person who, at the time of the communication, was an employee of Weibo, regardless of whether such employee was, is or becomes an employee of SINA or any of its subsidiaries or VIEs and (z) all Information generated, received or arising after the Public Filing Date that refers or relates to Privileged Information of Weibo generated, received or arising prior to the Public Filing Date.

(b) Upon receipt by a Party or its subsidiaries or VIE(s) of any subpoena, discovery or other request from any third party that actually or arguably calls for the production or disclosure of Privileged Information of the other Party or its subsidiaries or VIE(s), or if a Party or any of its subsidiaries or VIE(s) obtains knowledge that any of its current or former employees has received any subpoena, discovery or other request from any third party that actually or arguably calls for the production or disclosure of Privileged Information of the other Party or its subsidiaries or VIE(s), such Party shall promptly notify that other Party of the existence of the request and shall provide that other Party a reasonable opportunity to review the Information and to assert any rights such other Party may have under this Section 4.7 or otherwise to prevent the production or disclosure of Privileged Information. SINA or its subsidiaries or VIEs, or Weibo or its subsidiaries and VIE, as the case may be, will not produce or disclose to any third party any of the other Party’s Privileged Information under this Section 4.7 unless (a) such other Party has provided its express written consent to such production or disclosure or (b) a court of competent jurisdiction has entered an order not subject to interlocutory appeal or review finding that the Information is not entitled to protection from disclosure under any applicable privilege, doctrine or rule.

(c) SINA’s transfer of books and records pertaining to the Weibo Business and other Information pertaining to Weibo, if any, SINA’s agreement to permit Weibo to obtain Information existing prior to the Public Filing Date, Weibo’s transfer of books and records and other Information pertaining to SINA, if any, and Weibo’s agreement to permit SINA to obtain Information existing prior to the Public Filing Date are made in reliance on SINA’s and Weibo’s respective agreements, as set forth in Section 4.6 and this Section 4.7, to maintain the confidentiality of such Information and to take the steps provided herein for the preservation of all Privileges that may belong to or be asserted by SINA, or Weibo, as the case may be. The access to Information, witnesses and individuals being granted pursuant to Section 4.3 and Section 4.5 and the disclosure to one Party of Privileged Information relating to the other Party’s businesses pursuant to this Agreement shall not be asserted by SINA or Weibo to constitute, or otherwise be deemed, a waiver of any Privilege that has been or may be asserted under this Section 4.7 or otherwise. Nothing in this Agreement shall operate to reduce, minimize or condition the rights granted to, or the obligations imposed upon, SINA and Weibo by this Section 4.7.

Section 4.8 Future Litigation and Other Proceedings. In the event that Weibo (or any of its subsidiaries or VIE or any of its or their respective officers or directors) or SINA (or any of its subsidiaries or VIEs or any of its or their respective officers or directors) at any time after the date hereof initiates or becomes subject to any litigation or other proceedings before any Governmental Authority or arbitration panel with respect to which the Parties have no prior agreements (as to indemnification or otherwise), the Party (and its subsidiaries and VIE(s) and its and their respective officers and directors) that has not initiated and is not subject to such litigation or other proceedings shall comply, at the litigant Party’s expense, with any reasonable requests by the litigant Party for assistance in connection with such litigation or other proceedings (including by way of provision of Information and making available of employees as witnesses). In the event that Weibo (or any of its subsidiaries or VIE or any of its or their respective officers or directors) and SINA (or any of its subsidiaries or VIEs or any of its or their respective officers or directors), or any combination thereof, at any time after the date hereof initiate or become subject to any litigation or other proceedings before any Governmental Authority or arbitration panel with respect to which the litigant Parties have no prior agreements (as to indemnification or otherwise), each litigant Party (and its officers and directors) shall, at their own expense, coordinate their strategies and actions with respect to such litigation or other proceedings to the extent such coordination would not be detrimental to their respective interests and shall comply, at the expense of the requesting Party, with any reasonable requests of such Party for assistance in connection therewith (including by way of provision of information and making available of employees as witnesses).

Section 4.9 Mail and other Communications. Each of SINA and Weibo may receive mail, facsimiles, packages and other communications properly belonging to the other. Accordingly, each Party authorizes each of the other Party to receive and open all mail, telegrams, packages and other communications received by it and not unambiguously intended for the other Party or any of the other Party’ officers or directors, and to retain the same to the extent that they relate to the business of the receiving Party or, to the extent that they do not relate to the business of the receiving Party, the receiving Party shall promptly deliver such mail, telegrams, packages or other communications, including, without limitation, notices of any liens or encumbrances on any asset transferred to Weibo or its subsidiaries or VIE in connection with the separation from SINA, if any, (or, in case the same relate to both businesses, copies thereof) to the other Party as provided for in Section 7.6 hereof. The provisions of this Section 4.9 are not intended to, and shall not, be deemed to constitute (a) an authorization by either SINA or Weibo to permit the other to accept service of process on its behalf and no Party is or shall be deemed to be the agent of the other Party for service of process purposes or (b) a waiver of any Privilege with respect to Privileged Information contained in such mail, telegrams, packages or other communications.

Section 4.10 Other Inter-Company Services Agreements. To the extent not covered under the Inter-Company Agreements, SINA and its subsidiaries and VIEs, on the one hand, and Weibo and its subsidiaries and VIE, on the other, may enter into interim services agreements from time to time covering the provision of various interim services, if any, including financial, accounting, legal, and other services by SINA (and its subsidiaries and VIEs) to Weibo (and its subsidiaries and VIE) or, in certain circumstances, vice versa. Such services will generally be provided for a fee equal to the actual Direct Costs and Indirect Costs of providing such services plus an additional amount as agreed to by the Parties, subject to other consideration’s being agreed to by the Parties. “Direct Costs” shall include labor-related compensation and travel expenses, materials and supplies consumed and agency fees arising from performing the services. “Indirect Costs” shall include occupancy, information technology support and other overhead costs of the department incurring the direct costs of providing the service. Payment for any such services will be due within thirty (30) days after SINA renders an invoice for such services.

Section 4.11 Payment of Expenses. Except as otherwise provided in this Agreement, the Inter-Company Agreements or any other agreement between the Parties relating to the IPO, (i) all costs and expenses of the Parties in connection with the IPO (including costs associated with drafting this Agreement, the Inter-Company Agreements and the documents relating to the formation of Weibo and its subsidiaries and VIE) shall be paid by Weibo and (ii) all costs and expenses of the Parties in connection with any matter not relating to the IPO shall be paid by the Party which incurs such cost or expense. Notwithstanding the foregoing, Weibo and SINA shall each be responsible for their own internal fees, costs and expenses (e.g., salaries of personnel) incurred in connection with the IPO.

Section 5.4 Procedures for Defense, Settlement and Indemnification of the Third Party Claims.

(a) Notice of Claims. If an Indemnitee shall receive notice or otherwise learn of the assertion by a Person (including any Governmental Authority) other than SINA, Weibo and their subsidiaries and VIE(s) of any claim or of the commencement by any such Person of any Action (collectively, a “Third Party Claim”) with respect to which an Indemnifying Party may be obligated to provide indemnification, SINA or Weibo, as applicable, will ensure that such Indemnitee shall give such Indemnifying Party written notice thereof within thirty (30) days after becoming aware of such Third Party Claim. Any such notice shall describe the Third Party Claim in reasonable detail. Notwithstanding the foregoing, the delay or failure of any Indemnitee or other Person to give notice as provided in this Section 5.4 shall not relieve the related Indemnifying Party of its obligations under this Article 5, except to the extent that such Indemnifying Party is actually and substantially prejudiced by such delay or failure to give notice.

(b) Defense by Indemnifying Party. An Indemnifying Party shall be entitled to participate in the defense of any Third Party Claim and, to the extent that it wishes, at its cost, risk and expense, to assume the defense thereof, with counsel reasonably satisfactory to the Indemnitee, unless the Indemnifying Party is also a party to such proceeding and the Indemnitee determines in good faith that joint representation would be materially prejudicial to the Indemnitee’s defense. After timely notice from the Indemnifying Party to the Indemnitee of such election to so assume the defense thereof, the Indemnifying Party shall not be liable to the Indemnitee for any legal expenses of other counsel or any other expenses subsequently incurred by the Indemnitee in connection with the defense thereof. The Indemnitee agrees to cooperate in all reasonable respects with the Indemnifying Party and its counsel in the defense against any Third Party Claim. The Indemnifying Party shall be entitled to compromise or settle any Third Party Claim as to which it is providing indemnification, provided that any compromise or settlement shall be made only with the written consent of the Indemnitee, such consent not to be unreasonably withheld.

(c) Defense by Indemnitee. If an Indemnifying Party fails to assume the defense of a Third Party Claim within thirty (30) days after receipt of notice of such claim, the Indemnitee will, upon delivering notice to such effect to the Indemnifying Party, have the right to undertake the defense, compromise or settlement of such Third Party Claim on behalf of and for the account of the Indemnifying Party subject to the limitations as set forth in this Section 5.4; provided, however, that such Third Party Claim shall not be compromised or settled without the written consent of the Indemnifying Party, which consent shall not be unreasonably withheld. If the Indemnitee assumes the defense of any Third Party Claim, it shall keep the Indemnifying Party reasonably informed of the progress of any such defense, compromise or settlement. The Indemnifying Party shall reimburse all such costs and expenses of the Indemnitee in the event it is ultimately determined that the Indemnifying Party is obligated to indemnify the Indemnitee with respect to such Third Party Claim. In no event shall an Indemnifying Party be liable for any settlement effected without its consent, which consent shall not be unreasonably withheld.

Section 5.5 Additional Matters.

(a) Cooperation in Defense and Settlement. With respect to any Third Party Claim that implicates both Weibo and SINA in a material way due to the allocation of Liabilities, responsibilities for management of defense and related indemnities set forth in this Agreement or any of the Inter-Company Agreements, the Parties agree to cooperate fully and maintain a joint defense (in a manner that will preserve the attorney-client privilege, joint defense or other privilege with respect thereto) so as to minimize such Liabilities and defense costs associated therewith. Any Party that is not responsible for managing the defense of such Third Party Claims shall, upon reasonable request, be consulted with respect to significant matters relating thereto and may, if necessary or helpful, engage counsel to assist in the defense of such claims.

(b) Subrogation. In the event of payment by or on behalf of any Indemnifying Party to or on behalf of any Indemnitee in connection with any Third Party Claim, such Indemnifying Party shall be subrogated to and shall stand in the place of such Indemnitee, in whole or in part based upon whether the Indemnifying Party has paid all or only part of the Indemnitee’s Liability, as to any events or circumstances in respect of which such Indemnitee may have any right, defense or claim relating to such Third Party Claim against any claimant or plaintiff asserting such Third Party Claim or against any other person. Such Indemnitee shall cooperate with such Indemnifying Party in a reasonable manner, and at the cost and expense of such Indemnifying Party, in prosecuting any subrogated right, defense or claim.

Section 5.6 Survival of Indemnities. The rights and obligations of the Parties under this Article 5 shall survive the sale or other transfer by any Party of any of its assets or businesses or the assignment by it of any Liabilities or the acquisition of control of such Party (by sale of capital stock or other equity interests, merger, consolidation or otherwise).

ARTICLE 6

DISPUTE RESOLUTION

(a) Any dispute, controversy or claim arising out of or relating to this Agreement, Transitional Service Agreement or Non-Competition Agreement, or the breach, termination or validity thereof (“Dispute”) which arises between the Parties shall first be negotiated between appropriate senior executives of each Party who shall have the authority to resolve the matter. Such executives shall meet to attempt in good faith to negotiate a resolution of the Dispute prior to pursuing other available remedies, within ten (10) days of receipt by a Party of written notice of a Dispute, which date of receipt shall be referred to herein as the “Dispute Resolution Commencement Date.” Discussions and correspondence relating to trying to resolve such Dispute shall be treated as Confidential Information and Privileged Information of each of SINA and Weibo developed for the purpose of settlement and shall be exempt from discovery or production and shall not be admissible in any subsequent proceeding between the Parties.
