 Exhibit 10.3 

INDEMNIFICATION AGREEMENT 

THIS INDEMNIFICATION AGREEMENT (this “Agreement”) is made as
of            , by and between Weibo Corporation, an exempted company incorporated and existing under the laws of the Cayman Islands (the “Company”),
and        ([Passport/ID] Number        ) (the “Indemnitee”), a director/an executive officer of the Company. 

WHEREAS, the Indemnitee has agreed to serve as a director/an executive officer of the Company and in such capacity will render valuable
services to the Company; and 
 WHEREAS, in order to induce and encourage highly experienced and capable persons such as the Indemnitee to
serve as directors/an executive officer of the Company, the board of directors of the Company (the “Board of Directors”) has determined that this Agreement is not only reasonable and prudent, but necessary to promote and ensure the
best interests of the Company and its shareholders; 
 NOW, THEREFORE, in consideration of the premises and mutual agreements hereinafter
set forth, and other good and valuable consideration, including, without limitation, the service of the Indemnitee, the receipt of which hereby is acknowledged, and in order to induce the Indemnitee to serve as a director of the Company, the Company
and the Indemnitee hereby agree as follows: 
 1. Definitions. As used in this Agreement: 

(a) “Change in Control” shall mean a change in control of the Company of a nature that would be required to be
reported in response to Item 6(e) of Schedule 14A of Regulation 14A (or in response to any similar item on any similar or successor schedule or form) promulgated under the United States Securities Exchange Act of 1934, as amended, and the rules
and regulations promulgated thereunder (collectively, the “Act”), whether or not the Company is then subject to such reporting requirement; provided, however, that, without limitation, such a Change in Control shall be deemed to
have occurred (irrespective of the applicability of the initial clause of this definition) if (i) any “person” (as such term is used in Sections 13(d) and 14(d) of the Act, but excluding any trustee or other fiduciary holding
securities pursuant to an employee benefit or welfare plan or employee share plan of the Company or any subsidiary or affiliate of the Company, or any entity organized, appointed, established or holding securities of the Company with voting power
for or pursuant to the terms of any such plan) becomes the “beneficial owner” (as defined in Rule 13d-3 under the Act), directly or indirectly, of securities of the Company representing 30% or more of the combined voting power of the
Company’s then outstanding securities without the prior approval of at least two-thirds of the Continuing Directors (as defined below) in office immediately prior to such person’s attaining such interest; (ii) the Company is a party
to a merger, consolidation, scheme of arrangement, sale of assets or other reorganization, or a proxy contest, as a consequence of which Continuing Directors in office immediately prior to such transaction or event constitute less than a majority of
the Board of Directors of the Company (or any successor entity) thereafter; or (iii) during any period of two (2) consecutive years, individuals who at the beginning of such period constituted the Board of Directors of the Company
(including for this purpose any new director whose election or nomination for election by the Company’s shareholders was approved by a vote of at least two-thirds of the directors then still in office who were directors at the beginning of such
period) (such directors being referred to herein as “Continuing Directors”) cease for any reason to constitute at least a majority of the Board of Directors of the Company. 

  
 1 

 (b) “Disinterested Director” with respect to any request by the
Indemnitee for indemnification or advancement of expenses hereunder shall mean a director of the Company who neither is nor was a party to the Proceeding (as defined below) in respect of which indemnification or advancement is being sought by the
Indemnitee. 
 (c) The term “Expenses” shall mean, without limitation, expenses of Proceedings, including
attorneys’ fees, disbursements and retainers, accounting and witness fees, expenses related to preparation for service as a witness and to service as a witness, travel and deposition costs, expenses of investigations, judicial or administrative
proceedings and appeals, amounts paid in settlement of a Proceeding by or on behalf of the Indemnitee, costs of attachment or similar bonds, any expenses of attempting to establish or establishing a right to indemnification or advancement of
expenses, under this Agreement, the Company’s Memorandum of Association and Articles of Association as currently in effect (the “Articles”), applicable law or otherwise, and reasonable compensation for time spent by the
Indemnitee in connection with the investigation, defense or appeal of a Proceeding or action for indemnification for which the Indemnitee is not otherwise compensated by the Company or any third party. The term “Expenses” shall not include
the amount of judgments, fines, interest or penalties, or excise taxes assessed with respect to any employee benefit or welfare plan, which are actually levied against or sustained by the Indemnitee to the extent sustained after final adjudication.

 (d) The term “Independent Legal Counsel” shall mean any firm of attorneys reasonably selected by the Board of
Directors of the Company, so long as such firm has not represented the Company, the Company’s subsidiaries or affiliates, the Indemnitee, any entity controlled by the Indemnitee, or any party adverse to the Company, within the preceding five
(5) years. Notwithstanding the foregoing, the term “Independent Legal Counsel” shall not include any person who, under applicable standards of professional conduct then prevailing, would have a conflict of interest in representing
either the Company or the Indemnitee in an action to determine the Indemnitee’s right to indemnification or advancement of expenses under this Agreement, the Company’s Articles, applicable law or otherwise. 

(e) The term “Proceeding” shall mean any threatened, pending or completed action, suit, arbitration, alternate dispute
resolution mechanism, or other proceeding (including, without limitation, an appeal therefrom), formal or informal, whether brought in the name of the Company or otherwise, whether of a civil, criminal, administrative or investigative nature, and
whether by, in or involving a court or an administrative, other governmental or private entity or body (including, without limitation, an investigation by the Company or its Board of Directors), by reason of (i) the fact that the Indemnitee is
or was a director/an executive officer of the Company, or is or was serving at the request of the Company as an agent of another enterprise, whether or not the Indemnitee is serving in such capacity at the time any liability or expense is incurred
for which indemnification or reimbursement is to be provided under this Agreement, (ii) any actual or alleged act or omission or neglect or breach of duty, including, without limitation, any actual or alleged error or misstatement or misleading
statement, which the Indemnitee commits or suffers while acting in any such capacity, or (iii) the Indemnitee attempting to establish or establishing a right to indemnification or advancement of expenses pursuant to this Agreement, the
Company’s Articles, applicable law or otherwise. 

  
 2 

 (f) The phrase “serving at the request of the Company as an agent of another
enterprise” or any similar terminology shall mean, unless the context otherwise requires, serving at the request of the Company as a director, officer, employee or agent of another corporation, partnership, joint venture, limited liability
company, trust, employee benefit or welfare plan or other enterprise, foreign or domestic. The phrase “serving at the request of the Company” shall include, without limitation, any service as a director/an executive officer of the Company
which imposes duties on, or involves services by, such director/an executive officer with respect to the Company or any of the Company’s subsidiaries, affiliates, employee benefit or welfare plans, such plan’s participants or beneficiaries
or any other enterprise, foreign or domestic. In the event that the Indemnitee shall be a director, officer, employee or agent of another corporation, partnership, joint venture, limited liability company, trust, employee benefit or welfare plan or
other enterprise, foreign or domestic, 50% or more of the ordinary shares, combined voting power or total equity interest of which is owned by the Company or any subsidiary or affiliate thereof, then it shall be presumed conclusively that the
Indemnitee is so acting at the request of the Company. 
 2. Services by the Indemnitee. [For a director,] [The Indemnitee
agrees to serve as a director of the Company under the terms of the Indemnitee’s agreement with the Company for so long as the Indemnitee is duly elected or appointed or until such time as the Indemnitee tenders a resignation in writing or is
removed as a director; provided, however, that the Indemnitee may at any time and for any reason resign from such position (subject to any other contractual obligation or other obligation imposed by operation of law).]/[For an executive officer.]
[The Indemnitee agrees to serve as an executive officer of the Company under the terms of the Indemnitee’s agreement with the Company until such time as the Indemnitee’s employment is terminated for any reason.] 

3. Proceedings by or in the Right of the Company. The Company shall indemnify the Indemnitee if the Indemnitee is a party to or
threatened to be made a party to or is otherwise involved in any Proceeding by or in the right of the Company to procure a judgment in its favor by reason of the fact that the Indemnitee is or was a director/an executive officer of the Company, or
is or was serving at the request of the Company as an agent of another enterprise, against all Expenses, judgments, fines, interest or penalties, and excise taxes assessed with respect to any employee benefit or welfare plan, which are actually and
reasonably incurred by the Indemnitee in connection with the defense or settlement of such a Proceeding, if the Indemnitee acted in good faith and in a manner the Indemnitee reasonably believed to be in, or not opposed to, the best interests of the
Company; except that no indemnification under this section shall be made in respect of any claim, issue or matter as to which such person shall have been adjudicated by final judgment by a court of competent jurisdiction to be liable to the Company
for willful misconduct in the performance of his/her duty to the Company, unless and only to the extent that the court in which such Proceeding was brought shall determine upon application that, despite the adjudication of liability but in view of
all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such amounts which such other court shall deem proper. 

  
 3 

 4. Proceeding Other Than a Proceeding by or in the Right of the Company. The
Company shall indemnify the Indemnitee if the Indemnitee is a party to or threatened to be made a party to or is otherwise involved in any Proceeding (other than a Proceeding by or in the right of the Company), by reason of the fact that the
Indemnitee is or was a director/an executive officer of the Company, or is or was serving at the request of the Company as an agent of another enterprise, against all Expenses, judgments, fines, interest or penalties, and excise taxes assessed with
respect to any employee benefit or welfare plan, which are actually and reasonably incurred by the Indemnitee in connection with such a Proceeding, to the fullest extent permitted by applicable law; provided, however, that any settlement of a
Proceeding must be approved in advance in writing by the Company (which approval shall not be unreasonably withheld). 
 5.
Indemnification for Costs, Charges and Expenses of Witness or Successful Party. Notwithstanding any other provision of this Agreement (except as set forth in subparagraph 9(a) hereof), and without a requirement for determination as
required by Paragraph 8 hereof, to the extent that the Indemnitee (a) has prepared to serve or has served as a witness in any Proceeding in any way relating to (i) the Company or any of the Company’s subsidiaries, affiliates, employee
benefit or welfare plans or such plan’s participants or beneficiaries or (ii) anything done or not done by the Indemnitee as a director/an executive officer of the Company or in connection with serving at the request of the Company as an
agent of another enterprise, or (b) has been successful in defense of any Proceeding or in defense of any claim, issue or matter therein, on the merits or otherwise, including the dismissal of a Proceeding without prejudice or the settlement of
a Proceeding without an admission of liability, the Indemnitee shall be indemnified against all Expenses actually and reasonably incurred by the Indemnitee in connection therewith to the fullest extent permitted by applicable law. 

6. Partial Indemnification. If the Indemnitee is entitled under any provision of this Agreement to indemnification by the
Company for a portion of the Expenses, judgments, fines, interest or penalties, or excise taxes assessed with respect to any employee benefit or welfare plan, which are actually and reasonably incurred by the Indemnitee in the investigation,
defense, appeal or settlement of any Proceeding, but not, however, for the total amount of the Indemnitee’s Expenses, judgments, fines, interest or penalties, or excise taxes assessed with respect to any employee benefit or welfare plan, then
the Company shall nevertheless indemnify the Indemnitee for the portion of such Expenses, judgments, fines, interest or penalties or excise taxes to which the Indemnitee is entitled. 

7. Advancement of Expenses. The Expenses incurred by the Indemnitee in any Proceeding shall be paid promptly by the Company in
advance of the final disposition of the Proceeding at the written request of the Indemnitee to the fullest extent permitted by applicable law; provided, however, that the Indemnitee shall set forth in such request reasonable evidence that such
Expenses have been incurred by the Indemnitee in connection with such Proceeding, a statement that such Expenses do not relate to any matter described in subparagraph 9(a) of this Agreement, and an undertaking in writing to repay any advances if it
is ultimately determined as provided in subparagraph 8(b) of this Agreement that the Indemnitee is not entitled to indemnification under this Agreement. 

8. Indemnification Procedure; Determination of Right to Indemnification. 

(a) Promptly after receipt by the Indemnitee of notice of the commencement of any Proceeding, the Indemnitee shall, if a claim for
indemnification or advancement of Expenses in respect thereof is to be made against the Company under this Agreement, notify the Company of the commencement thereof in writing. The omission to so notify the Company will not relieve the Company from
any liability which the Company may have to the Indemnitee under this Agreement unless the Company shall have lost significant substantive or procedural rights with respect to the defense of any Proceeding as a result of such omission to so notify.

  
 4 

 (b) The Indemnitee shall be conclusively presumed to have met the relevant standards of
conduct, if any, as defined by applicable law, for indemnification pursuant to this Agreement and shall be absolutely entitled to such indemnification, unless a determination is made that the Indemnitee has not met such standards by (i) the
Board of Directors by a majority vote of a quorum thereof consisting of Disinterested Directors, (ii) the shareholders of the Company by majority vote of a quorum thereof consisting of shareholders who are not parties to the Proceeding due to
which a claim for indemnification is made under this Agreement, (iii) Independent Legal Counsel as set forth in a written opinion (it being understood that such Independent Legal Counsel shall make such determination only if the quorum of
Disinterested Directors referred to in clause (i) of this subparagraph 8(b) is not obtainable or if the Board of Directors of the Company by a majority vote of a quorum thereof consisting of Disinterested Directors so directs), or (iv) a
court of competent jurisdiction; provided, however, that if a Change of Control shall have occurred and the Indemnitee so requests in writing, such determination shall be made only by a court of competent jurisdiction. 

(c) If a claim for indemnification or advancement of Expenses under this Agreement is not paid by the Company within thirty
(30) days after receipt by the Company of written notice thereof, the rights provided by this Agreement shall be enforceable by the Indemnitee in any court of competent jurisdiction. Such judicial proceeding shall be made de novo. The burden of
proving that indemnification or advances are not appropriate shall be on the Company. Neither the failure of the directors or shareholders of the Company or Independent Legal Counsel to have made a determination prior to the commencement of such
action that indemnification or advancement of Expenses is proper in the circumstances because the Indemnitee has met the applicable standard of conduct, if any, nor an actual determination by the directors or shareholders of the Company or
Independent Legal Counsel that the Indemnitee has not met the applicable standard of conduct shall be a defense to an action by the Indemnitee or create a presumption for the purpose of such an action that the Indemnitee has not met the applicable
standard of conduct. The termination of any Proceeding by judgment, order, settlement or conviction, or upon a plea of nolo contendere or its equivalent, shall not, of itself (i) create a presumption that the Indemnitee did not act in
good faith and in a manner which he reasonably believed to be in the best interests of the Company and/or its shareholders, and, with respect to any criminal Proceeding, that the Indemnitee had reasonable cause to believe that his conduct was
unlawful or (ii) otherwise adversely affect the rights of the Indemnitee to indemnification or advancement of Expenses under this Agreement, except as may be provided herein. 

(d) If a court of competent jurisdiction shall determine that the Indemnitee is entitled to any indemnification or advancement of
Expenses hereunder, the Company shall pay all Expenses actually and reasonably incurred by the Indemnitee in connection with such adjudication (including, but not limited to, any appellate proceedings). 

  
 5 

 (e) With respect to any Proceeding for which indemnification or advancement of Expenses is
requested, the Company will be entitled to participate therein at its own expense and, except as otherwise provided below, to the extent that it may wish, the Company may assume the defense thereof, with counsel reasonably satisfactory to the
Indemnitee. After notice from the Company to the Indemnitee of its election to assume the defense of a Proceeding, the Company will not be liable to the Indemnitee under this Agreement for any Expenses subsequently incurred by the Indemnitee in
connection with the defense thereof, other than as provided below. The Company shall not settle any Proceeding in any manner which would impose any penalty or limitation on the Indemnitee without the Indemnitee’s written consent. The Indemnitee
shall have the right to employ his own counsel in any Proceeding, but the fees and expenses of such counsel incurred after notice from the Company of its assumption of the defense of the Proceeding shall be at the expense of the Indemnitee, unless
(i) the employment of counsel by the Indemnitee has been authorized by the Company, (ii) the Indemnitee shall have reasonably concluded that there may be a conflict of interest between the Company and the Indemnitee in the conduct of the
defense of a Proceeding, or (iii) the Company shall not in fact have employed counsel to assume the defense of a proceeding, in each of which cases the fees and expenses of the Indemnitee’s counsel shall be advanced by the Company. The
Company shall not be entitled to assume the defense of any Proceeding brought by or on behalf of the Company or as to which the Indemnitee has reasonably concluded that there may be a conflict of interest between the Company and the Indemnitee. 

9. Limitations on Indemnification. No payments pursuant to this Agreement shall be made by the Company: 

(a) To indemnify or advance funds to the Indemnitee for Expenses with respect to (i) Proceedings initiated or brought voluntarily
by the Indemnitee and not by way of defense, except with respect to Proceedings brought to establish or enforce a right to indemnification under this Agreement or any other statute or law or otherwise as required under applicable law or
(ii) Expenses incurred by the Indemnitee in connection with preparing to serve or serving, prior to a Change in Control, as a witness in cooperation with any party or entity who or which has threatened or commenced any action or proceeding
against the Company, or any director, officer, employee, trustee, agent, representative, subsidiary, parent corporation or affiliate of the Company, but such indemnification or advancement of Expenses in each such case may be provided by the Company
if the Board of Directors finds it to be appropriate; 
 (b) To indemnify the Indemnitee for any Expenses, judgments, fines, interest
or penalties, or excise taxes assessed with respect to any employee benefit or welfare plan, sustained in any Proceeding for which payment is actually made to the Indemnitee under a valid and collectible insurance policy, except in respect of any
excess beyond the amount of payment under such insurance; 
 (c) To indemnify the Indemnitee for any Expenses, judgments, fines,
interest or penalties sustained in any Proceeding for an accounting of profits made from the purchase or sale by the Indemnitee of securities of the Company pursuant to the provisions of Section 16(b) of the Act or similar provisions of any
foreign or United States federal, state or local statute or regulation; 
 (d) To indemnify the Indemnitee for any Expenses,
judgments, fines, interest or penalties, or excise taxes assessed with respect to any employee benefit or welfare plan, for which the Indemnitee is indemnified by the Company otherwise than pursuant to this Agreement; 

(e) To indemnify the Indemnitee for any Expenses (including without limitation any Expenses relating to a Proceeding attempting to
enforce this Agreement), judgments, fines, interest or penalties, or excise taxes assessed with respect to any employee benefit or welfare plan, on account of the Indemnitee’s conduct if such conduct shall be finally adjudged to have been
knowingly fraudulent, deliberately dishonest or willful misconduct, including, without limitation, breach of the duty of loyalty; or 

  
 6 

 (f) If a court of competent jurisdiction finally determines that any indemnification
hereunder is unlawful. In this respect, the Company and the Indemnitee have been advised that the Securities and Exchange Commission takes the position that indemnification for liabilities arising under securities laws is against public policy and
is, therefore, unenforceable and that claims for indemnification should be submitted to appropriate courts for adjudication; 
 (g)
To indemnify the Indemnitee in connection with Indemnitee’s personal tax matter; or 
 (h) To indemnify the Indemnitee with
respect to any claim related to any dispute or breach arising under any contract or similar obligation between the Company or any of its subsidiaries or affiliates and such Indemnitee. 

10. Continuation of Indemnification. All agreements and obligations of the Company contained herein shall continue during the
period that the Indemnitee is a director/an executive officer of the Company (or is or was serving at the request of the Company as an agent of another enterprise, foreign or domestic) and shall continue thereafter so long as the Indemnitee shall be
subject to any possible Proceeding by reason of the fact that the Indemnitee was a director/an executive officer of the Company or serving in any other capacity referred to in this Paragraph 10. 

11. Indemnification Hereunder Not Exclusive. The indemnification provided by this Agreement shall not be deemed to be exclusive
of any other rights to which the Indemnitee may be entitled under the Company’s Articles, any agreement, vote of shareholders or vote of Disinterested Directors, provisions of applicable law, or otherwise, both as to action or omission in the
Indemnitee’s official capacity and as to action or omission in another capacity on behalf of the Company while holding such office. 

12. Successors and Assigns. 

(a) This Agreement shall be binding upon the Indemnitee, and shall inure to the benefit of, the Indemnitee and the Indemnitee’s
heirs, executors, administrators and assigns, whether or not the Indemnitee has ceased to be a director/an executive officer, and the Company and its successors and assigns. Upon the sale of all or substantially all of the business, assets or share
capital of the Company to, or upon the merger of the Company into or with, any corporation, partnership, joint venture, trust or other person, this Agreement shall inure to the benefit of and be binding upon both the Indemnitee and such purchaser or
successor person. Subject to the foregoing, this Agreement may not be assigned by either party without the prior written consent of the other party hereto. 

(b) If the Indemnitee is deceased and is entitled to indemnification under any provision of this Agreement, the Company shall indemnify
the Indemnitee’s estate and the Indemnitee’s spouse, heirs, executors, administrators and assigns against, and the Company shall, and does hereby agree to assume, any and all Expenses actually and reasonably incurred by or for the
Indemnitee or the Indemnitee’s estate, in connection with the investigation, defense, appeal or settlement of any Proceeding. Further, when requested in writing by the spouse of the Indemnitee, and/or the Indemnitee’s heirs, executors,
administrators and assigns, the Company shall provide appropriate evidence of the Company’s agreement set out herein to indemnify the Indemnitee against and to itself assume such Expenses. 

  
 7 

 13. Subrogation. In the event of payment under this Agreement, the Company shall be
subrogated to the extent of such payment to all of the rights of recovery of the Indemnitee, who shall execute all documents required and shall do all acts that may be necessary to secure such rights and to enable the Company effectively to bring
suit to enforce such rights. 
 14. Severability. Each and every paragraph, sentence, term and provision of this Agreement is
separate and distinct so that if any paragraph, sentence, term or provision thereof shall be held to be invalid, unlawful or unenforceable for any reason, such invalidity, unlawfulness or unenforceability shall not affect the validity, unlawfulness
or enforceability of any other paragraph, sentence, term or provision hereof. To the extent required, any paragraph, sentence, term or provision of this Agreement may be modified by a court of competent jurisdiction to preserve its validity and to
provide the Indemnitee with the broadest possible indemnification permitted under applicable law. The Company’s inability, pursuant to a court order or decision, to perform its obligations under this Agreement shall not constitute a breach of
this Agreement. 
 15. Savings Clause. If this Agreement or any paragraph, sentence, term or provision hereof is invalidated
on any ground by any court of competent jurisdiction, the Company shall nevertheless indemnify the Indemnitee as to any Expenses, judgments, fines, interest or penalties, or excise taxes assessed with respect to any employee benefit or welfare plan,
which are incurred with respect to any Proceeding to the fullest extent permitted by any (a) applicable paragraph, sentence, term or provision of this Agreement that has not been invalidated or (b) applicable law. 

16. Interpretation; Governing Law. This Agreement shall be construed as a whole and in accordance with its fair meaning and any
ambiguities shall not be construed for or against either party. Headings are for convenience only and shall not be used in construing meaning. This Agreement shall be governed and interpreted in accordance with the laws of the State of New York
without regard to the conflict of laws principles thereof. 
 17. Amendments. No amendment, waiver, modification, termination
or cancellation of this Agreement shall be effective unless in writing signed by the party against whom enforcement is sought. The indemnification rights afforded to the Indemnitee hereby are contract rights and may not be diminished, eliminated or
otherwise affected by amendments to the Company’s Articles, or by other agreements, including directors’ and officers’ liability insurance policies, of the Company. 

18. Counterparts. This Agreement may be executed in one or more counterparts, all of which shall be considered one and the same
agreement and shall become effective when one or more counterparts have been signed by each party and delivered to the other. 
 19.
Notices. Any notice required to be given under this Agreement shall be directed to the Chief Financial Officer of the Company at 7/F, Shuohuang Development Plaza, No. 6 Caihefang Road, Haidian District, Beijing, 100080, People’s
Republic of China, and to the Indemnitee at or to such other address as either shall designate to the other in writing.

 MASTER TRANSACTION AGREEMENT 

This Master Transaction Agreement is dated as of March 14, 2014, by and between SINA Corporation, an exempted company with limited
liability incorporated under the laws of the Cayman Islands (“SINA”), and Weibo Corporation, an exempted company with limited liability incorporated under the laws of the Cayman Islands (“Weibo”) (each of SINA and
Weibo a “Party” and, together, the “Parties”). 
 Capitalized terms used herein and not otherwise defined
shall have the meanings ascribed to such terms in Article 1 hereof. 
 R E C I T A L S 

WHEREAS, as of the date hereof, SINA owns 140,000,000 issued and outstanding Ordinary Shares of Weibo, representing 77.6% of total number of
Ordinary Shares of Weibo on an as-converted basis; 
 WHEREAS, SINA has been engaged in the Weibo Business through Weibo and/or Weibo’s

its subsidiaries and VIEs. 
 (h) Notice of Change in Accounting Principles. Until the Control Ending Date, and thereafter if a
change in accounting principles by a Party would affect the historical financial statements of the other Party, no such Party shall make or adopt any significant changes in its accounting estimates or accounting principles from those in effect on
the Public Filing Date without first consulting with the other Party, and if requested by the other Party, such other Party’s independent registered public accounting firm with respect thereto. SINA shall give Weibo as much prior notice as

(i) Conflict With Third-Party Agreements. Nothing in Section 4.3 or this Section 4.5 shall require a Party to violate any
agreement with any third party regarding the confidentiality of confidential and proprietary Information relating to that third party or its business; provided, however, that in the event that a Party is required under Section 4.3 or this
Section 4.5 to disclose any such Information, such Party shall use its reasonable best efforts to seek to obtain such third party’s consent to the disclosure of such Information. 

  
 13 

 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. In the event that an appropriate protective order or other remedy is not obtained, the Party whose Confidential Information is required to be disclosed shall or
shall cause the notifying Party to furnish, or cause to be furnished, only that portion of the Confidential Information that is required to be disclosed and shall use its reasonable best efforts to obtain reasonable assurances that confidential
treatment will be accorded to such Information. 
 (b) As used in this Section 4.6: 

(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. 

  
 14

and forecasts, (b) proprietary macro-economic reports and forecasts, (c) proprietary business plans, (d) proprietary general market evaluations and surveys, (e) proprietary financing and credit-related information, and
(f) customer information. 
 (c) Nothing in this Agreement shall restrict (i) the disclosing Party from using, disclosing, or
disseminating its own Confidential Information in any way, or (ii) reassignment of the receiving Party’s employees. 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. 

  
 15 

 Section 4.7 Privileged Matters. 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 SINA includes but is not limited to (i) any and all Information regarding the
business of SINA and its subsidiaries and VIEs (other than Information regarding the Weibo Business), whether or not it is in the possession of Weibo or any of its subsidiaries and VIE; (ii) all communications subject to a Privilege between
counsel for SINA (including in-house counsel) and any individual who, at the time of the communication, was an employee of SINA, regardless of whether such employee is or becomes an employee of Weibo or any of its subsidiaries and VIE and
(iii) all Information generated, received or arising after the Public Filing Date that refers or relates to Privileged Information of SINA generated, received or arising prior to the Public Filing Date. 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. 

  
 16 

 (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. 

  
 17 

 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.

any action or inaction of SINA or any of its subsidiaries or VIEs, including as a result of any misstatement or omission of any information by SINA or its subsidiaries or VIEs to Weibo.

 In the event that Weibo or any of its subsidiaries or VIE makes a payment to the SINA Indemnitees
hereunder, and any of the SINA Indemnitees subsequently diminishes the Liability on account of which such payment was made, either directly or through a third-party recovery (other than a recovery indirectly from SINA or its subsidiaries or VIEs),
SINA will promptly repay (or will procure an SINA Indemnitee to promptly repay) Weibo (or its subsidiary or VIE that has made the payment) the amount by which the payment made by Weibo (or its subsidiary or VIE that has made the payment) exceeds the
actual cost of the associated indemnified Liability.

 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. 

  
 21 

 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 
 Section 6.1 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. 

(b) If the senior executives are unable to resolve the Dispute within 60 days from the Dispute Resolution Commencement Date, then, the
Dispute will be submitted to the boards of directors of SINA and Weibo. Representatives of each board of directors shall meet as soon as practicable to attempt in good faith to negotiate a resolution of the Dispute. 

  
 22 

 (c) If the representatives of the two boards of directors are unable to resolve the Dispute
within 120 days from the Dispute Resolution Commencement Date, on the request of any Party, the Dispute will be mediated by a mediator appointed pursuant to the mediation rules of the American Arbitration Association. Both Parties will share the
administrative costs of the mediation and the mediator’s fees and expenses equally, and each Party shall bear all of its other costs and expenses related to the mediation, including but not limited to attorney’s fees, witness fees, and
travel expenses. The mediation shall take place in Beijing, China or in whatever alternative forum on which the Parties may agree.
