OUR COMPANY

Overview

        Weibo is a leading social media platform for people to create, distribute, and discover content. It provides an unprecedented and simple way for people and organizations to publicly express themselves in real time, interact with others on a massive global platform, and stay connected with the world.

        Weibo combines the means of public self-expression in real time with a powerful platform for social interaction, content aggregation, and content distribution. Any user can create and post a feed and attach multimedia or long-form content. User relationships on Weibo may be asymmetric; any user can follow any other user and add comments to a feed while reposting. The simple, asymmetric, and distributed nature of Weibo allows an original feed to become a live viral conversation stream.

        Weibo serves a wide range of users including ordinary people, celebrities, and other public figures, as well as media outlets, businesses, government agencies, charities, and other organizations, making it a microcosm of Chinese society. For many people in China, Weibo allows them to be heard publicly and exposed to the rich ideas, cultures, and experiences of the broader world.

        In addition to users, Weibo's ecosystem includes customers and platform partners:

•

Customers.  We enable our advertising and marketing customers to promote their brands, products, and services to our users. We offer a wide range of advertising and marketing solutions to customers ranging from large companies to small and medium-sized enterprises, or SMEs, including social display advertisement and promoted marketing offerings. Our native promoted marketing offerings allow customers to reach a targeted audience based on the social interest graph, or SIG, of our users. In addition, our customers can benefit from the potential viral effect of their promoted feeds generated from the public and distributed nature of our platform, commonly known as "earned media."

•

Platform Partners.  We have attracted a large number of platform partners, including organizations with media rights, multi-channel networks, self-medias, and app developers. Our platform partners contribute a vast amount of content to Weibo, broadly distribute Weibo content across their properties and integrate products and applications with our platform, enriching the experience of our users while increasing our monetization opportunities.

        While we distinguish among users, customers, and platform partners in classifying our products and analyzing our revenues, the same person or organization may simultaneously be included in two or more of the categories.

        We began monetization on our platform in 2012, and we have since experienced rapid revenue growth. Our revenues increased from US$655.8 million in 2016 to US$1,150.1 million in 2017, and further to US$1,718.5 million in 2018, representing a compound annual growth rate, or CAGR, of 62%. Our revenues for the three months ended March 31, 2019 was US$399.2 million, compared to US$349.9 million for the three months ended March 31, 2018. We generate revenues primarily from customers who purchase advertising and marketing services, and, to a lesser extent, from fee-based revenues, such as VIP membership. For the year ended December 31, 2018 and the three months ended March 31, 2019, revenues generated from advertising and marketing services accounted for 87% and 85% of our total revenues, respectively. In addition, our net income attributable to Weibo increased significantly from US$108.0 million in 2016 to US$352.6 million in 2017, and further to US$571.8 million in 2018. Our net income attributable to Weibo for the three months ended March 31, 2019 was US$150.4 million, an increase of 52% compared to US$99.1 million for the three months ended March 31, 2018. For the year ended December 31, 2018 and the three months ended March 31, 2019, we had US$488.0 million and US$80.8 million net cash from operating activities, respectively. As

3

of March 31, 2019, we held an aggregate of US$1,493.2 million of cash and cash equivalents and short-term investments.

General

        We may sell the debt securities, including original issue discount securities, at par or at greater than de minimis discount below their stated principal amount. Unless we inform you otherwise in a prospectus supplement, we may issue additional debt securities of a particular series without the consent of the holders of the debt securities of such series outstanding at the time of issuance. Any such additional debt securities, together with all other outstanding debt securities of that series, will constitute a single series of debt securities under the indenture. Such additional debt securities will have the same terms and conditions as the applicable series of debt securities in all respects (or in all respects except for the issue date, the issue price, the first date for accrual of interest or the first payment of interest), and will vote together as one class on all matters with respect to such series of debt securities. We shall not issue any additional debt securities with the same CUSIP, ISIN or other identifying number as the debt securities of that series issued hereunder unless the additional debt securities are fungible with such debt securities for U.S. federal income tax purposes. In addition, we will describe in the applicable prospectus supplement material U.S. federal tax considerations and any

8

other special considerations for any debt securities we sell which are denominated in a currency or currency unit other than U.S. dollars. Unless we inform you otherwise in the applicable prospectus supplement, the debt securities will not be listed on any securities exchange.

Form, Exchange and Transfer

        The debt securities will be issued, unless otherwise indicated in the applicable prospectus supplement, in fully registered form without interest coupons and in minimum denominations of US$2,000 and integral multiples of US$1,000 in excess thereof.

        You may exchange or transfer your registered debt securities at the office of the trustee. The trustee acts as our agent for registering debt securities in the names of holders and transferring registered debt securities. The entity performing the role of maintaining the list of registered holders is called the "registrar." It will also register transfers of the registered debt securities. We may also arrange for additional registrars, and may change registrars. We may also choose to act as our own registrar.

        You will not be required to pay a service charge for any registration of transfer or exchange of debt securities, but you may be required to pay any tax or other governmental charge associated with the registration of transfer or exchange. The registration of transfer or exchange of a registered debt security will only be made if you have duly endorsed the debt security or provided the registrar with a written instrument of transfer satisfactory in form to the registrar.

Payment and Paying Agents

        If your debt securities are in definitive registered form, we will pay interest to you if you are listed in the paying agent's records as a direct holder at the close of business on a particular day in advance of each due date for interest, even if you no longer own the debt securities on the interest due date. That particular day is called the "record date" and will be stated in the applicable prospectus supplement.

        We will pay interest, principal, additional amounts and any other money due on global registered debt securities pursuant to the applicable procedures of the depositary or, if the debt securities are not in global form, at offices maintained for that purpose in New York, New York. These offices are called "paying agents." We may also choose to pay interest by mailing checks. We may also arrange for additional payment agents, and may change these agents, including our use of the paying agent's specified office. We may also choose to act as our own paying agent.

        Regardless of who acts as paying agent, all money that we pay as principal, premium or interest to a paying agent, or then held by us in trust, that remains unclaimed at the end of two years after the amount is due to direct holders will be repaid to us, or if then held by us, discharged from trust. After that two-year period, direct holders may look only to us for payment and not to the trustee, any other paying agent or anyone else.

Street name and other indirect holders should consult their banks or brokers for information on how they will receive payments.

Payment of Additional Amounts

        All payments of principal, premium and interest made by us in respect of any debt security will be made without withholding or deduction for, or on account of, any present or future taxes, duties, assessments or governmental charges of whatever nature (including any penalties and interest related thereto) ("Taxes") imposed or levied by or within the Cayman Islands, Hong Kong, China or any jurisdiction where we are organized or otherwise considered by a taxing authority to be a resident for tax purposes or through which a payment in respect of a debt security is made (in each case, including

9

any political subdivision or any authority therein or thereof having power to tax) (each, a "Relevant Jurisdiction"), unless such withholding or deduction of such Taxes is required by law. If we are required to make such withholding or deduction, we will pay such additional amounts ("Additional Amounts") as will result in receipt by each holder or beneficial owner of any debt security of such amounts as would have been received by such holder or beneficial owner had no such withholding or deduction of such Taxes been required, except that no such Additional Amounts shall be payable:

i.

in respect of any such Taxes that would not have been imposed, deducted or withheld but for the existence of any connection (whether present or former) between the holder or beneficial owner of a debt security and the Relevant Jurisdiction other than merely holding such debt security or receiving principal, premium (if any) or interest, or enforcing its rights, in respect thereof (including such holder or beneficial owner being or having been a national, domiciliary or resident of such Relevant Jurisdiction or treated as a resident thereof or being or having been physically present or engaged in a trade or business therein or having or having had a permanent establishment therein);



ii.

in respect of any debt security presented for payment (where presentation is required) more than 30 days after the relevant date, except to the extent that the holder thereof would have been entitled to such Additional Amounts on presenting the same for payment on the last day of such 30-day period. For this purpose, the "relevant date" in relation to any debt security means the later of (a) the due date for such payment or (b) the date such payment was made or duly provided for;



iii.

in respect of any Taxes that would not have been imposed, deducted or withheld but for a failure of the holder or beneficial owner of a debt security to comply with a timely request by us addressed to the holder or beneficial owner to provide information concerning such holder's or beneficial owner's nationality, residence, identity or connection with any Relevant Jurisdiction, if and to the extent that due and timely compliance with such request is required under the tax laws of such jurisdiction in order to reduce or eliminate any withholding or deduction as to which Additional Amounts would have otherwise been payable to such holder or beneficial owner;



iv.

in respect of any Taxes imposed as a result of a debt security being presented for payment (where presentation is required) in the Relevant Jurisdiction, unless such debt security could not have been presented for payment elsewhere;



v.

in respect of any estate, inheritance, gift, sales, transfer, personal property or similar Taxes;



vi.

to any holder of a debt security that is a fiduciary, partnership or person other than the sole beneficial owner of any payment to the extent that such payment would be required to be included in the income under the laws of a Relevant Jurisdiction, for tax purposes, of a beneficiary or settlor with respect to the fiduciary, or a member of that partnership or a beneficial owner who would not have been entitled to such Additional Amounts had that beneficiary, settlor, partner or beneficial owner been the holder thereof;



vii.

with respect to any withholding or deduction that is imposed in connection with Sections 1471-1474 of the U.S. Internal Revenue Code and U.S. Treasury regulations thereunder ("FATCA"), any intergovernmental agreement between the United States and any other jurisdiction implementing or relating to FATCA or any non-U.S. law, regulation or guidance enacted or issued with respect thereto;



viii.

in respect of any such Taxes payable otherwise than by deduction or withholding from payments under or with respect to any debt security; or

10

ix.

in respect of any combination of Taxes referred to in the preceding items (i) through (viii) above.

        If any Taxes are deducted or withheld from payments of principal of, premium (if any) or interest on any debt securities, we will furnish to the trustee, within 30 days after the date the payment of such Taxes is due pursuant to applicable law, either certified copies of tax receipts evidencing such payment or, if such receipts are not obtainable, other evidence of payments reasonably satisfactory to the trustee. Upon request, copies of those receipts or other evidence of payments, as the case may be, will be made available by the trustee to the holders or beneficial owners of the debt securities.

        We will pay any stamp, issue, registration, court, documentary or value added taxes, or any other excise or property taxes, charges or similar levies (including, in each case, interest and penalties) payable in respect of the creation, issue, offering, execution, delivery, registration, enforcement or making payments in respect of the debt securities or any documentation with respect thereto, excluding any such taxes, charges or similar levies imposed by any jurisdiction other than a Relevant Jurisdiction except those resulting from, or required to be paid in connection with, the enforcement of the debt securities after the occurrence and during the continuance of an Event of Default with respect to the debt securities.

        Whenever there is mentioned, in any context, the payment of principal, premium or interest in respect of any debt security, such mention shall be deemed to include the payment of Additional Amounts provided for in the indenture, to the extent that, in such context, Additional Amounts are, were or would be payable in respect thereof pursuant to the indenture.

        The foregoing provisions shall apply in the same manner with respect to the jurisdiction in which any successor Person to us is organized or resident for tax purposes or any political subdivision or any authority therein or thereof having the power to tax (a "Successor Jurisdiction"), substituting such Successor Jurisdiction for the Relevant Jurisdiction.

        Our obligation to make payments of Additional Amounts under the terms and conditions described above will survive any termination, defeasance or discharge of the indenture.

Tax Redemption

        Each series of debt securities may be redeemed at any time, at our option, in whole but not in part, upon notice as described below, at a redemption price equal to 100% of the principal amount thereof, together with accrued and unpaid interest, if any, to, but not including, the date fixed for redemption, if (i) as a result of any change in, or amendment to, the laws or regulations of the Relevant Jurisdiction (or, in the case of Additional Amounts payable by a successor Person to us, the applicable Successor Jurisdiction), or any change in the official application or official interpretation of such laws or regulations, which change or amendment becomes effective on or after the issue date of the applicable series of debt securities (or, in the case of Additional Amounts payable by a successor Person to us, the date on which such successor Person to us became such pursuant to the applicable provisions of the indenture) (a "Tax Change"), we or any such successor Person to us is, or would be, obligated to pay Additional Amounts upon the next payment of principal, premium (if any) or interest in respect of such debt securities and (ii) such obligation cannot be avoided by us or any such successor Person to us taking reasonable measures available to it, provided that changing our or such successor Person's jurisdiction is not a reasonable measure for purposes of this section.

        Prior to the giving of any notice of redemption of debt securities pursuant to the foregoing, we or any such successor Person to us shall deliver to the trustee (i) a notice of such redemption election, (ii) an opinion of an independent legal counsel or an opinion of an independent tax consultant to the effect that we or any such successor Person to us is, or would become, obligated to pay such Additional Amounts as the result of a Tax Change and (iii) an officers' certificate from us or any such successor

11

Person to us, stating that such amendment or change has occurred, describing the facts leading thereto and stating that such requirement cannot be avoided by us or any such successor Person to us taking reasonable measures available to it.

        Notice of redemption of debt securities as provided above shall be given to the holders not less than 30 nor more than 60 days prior to the date fixed for redemption; provided that no such notice of redemption shall be given earlier than 90 days prior to the earliest date on which we or any such successor Person to us would be required to pay Additional Amounts if a payment in respect of such debt securities was then due. Notice having been given, the debt securities of that series shall become due and payable on the date fixed for redemption and will be paid at the redemption price, together with accrued and unpaid interest, if any, to, but not including, the date fixed for redemption, at the place or places of payment and in the manner specified in that series of the debt securities. From and after the redemption date, if moneys for the redemption of such debt securities shall have been made available as provided in the indenture for redemption on the redemption date, the debt securities of such series shall cease to bear interest, and the only right of the holders of such debt securities shall be to receive payment of the redemption price and accrued and unpaid interest, if any, to, but not including, the date fixed for redemption.

Open Market Purchases

        We or any of our Controlled Entities may, in accordance with all applicable laws and regulations, at any time purchase the debt securities issued under the indenture in the open market or otherwise at any price, so long as such purchase does not otherwise violate the terms of the indenture. The debt securities so purchased, while held by or on behalf of us or any of our Controlled Entities, shall not be deemed to be outstanding for the purposes of determining whether the holders of the requisite principal amount of outstanding debt securities have given any request, demand, authorization, direction, notice, consent or waiver hereunder.

Modification and Waiver

        The indenture contains provisions permitting us and the trustee, without the consent of the holders of the applicable series of debt securities, to execute supplemental indentures for certain enumerated purposes in the indenture and, with the consent of the holders of not less than a majority in aggregate principal amount of the applicable series of debt securities then outstanding under the indenture, to add, change, eliminate or modify in any way the provisions of the indenture or any supplemental indentures or to change or modify in any manner the rights of the holders of such debt securities. We and the trustee may not, however, without the consent of each holder of the debt securities of the applicable series affected thereby:

i.

change the Stated Maturity of any debt security;



ii.

reduce the principal amount of, payments of interest on or stated time for payment of interest on any debt security;



iii.

change any obligation of ours to pay Additional Amounts with respect to any debt security;



iv.

v.

vi.

impair the right to institute suit for the enforcement of any payment due on or with respect to any debt security;

12

vii.

reduce the amount of the premium payable upon the redemption or repurchase of any series of debt securities or change the time at which any series of debt securities may be redeemed or repurchased as described above under "—Tax Redemption" or as described in the applicable prospectus supplement.

        The holders of not less than a majority in principal amount of the debt securities of any series then outstanding may on behalf of all holders of the debt securities of that series waive any existing or past Default or Event of Default and its consequences under the indenture, except a continuing Default or Event of Default (i) in the payment of principal of, premium (if any) or interest on (or Additional Amount payable in respect of), the debt securities of such series then outstanding, in which event the consent of all holders of the debt securities of such series then outstanding affected thereby is required, or (ii) in respect of a covenant or provision which under the indenture cannot be modified or amended without the consent of the holder of each debt security of such series then outstanding affected thereby. Any such waivers will be conclusive and binding on all holders of that series of debt securities, whether or not they have given consent to such waivers, and on all future holders of such debt securities, whether or not notation of such waivers is made upon such debt securities. Any instrument given by or on behalf of any holder of a debt security of that series in connection with any consent to any such waiver will be irrevocable once given and will be conclusive and binding on all subsequent holders of such debt security.

        Notwithstanding the foregoing, without the consent of any holder of the securities, we and the trustee may amend the indenture and the relevant debt securities to, among other things:

i.

cure any ambiguity, omission, defect or inconsistency contained in the indenture or in any supplemental indenture; provided, however, that such amendment does not materially and adversely affect the rights of holders;

13

ix.

make any amendment to the provisions of the indenture relating to the transfer and legending of debt securities as permitted by the indenture, including, but not limited to, facilitating the issuance and administration of any series of the debt securities or, if incurred in compliance with the indenture, additional debt securities; provided, however, that (A) compliance with the indenture as so amended would not result in any series of the debt securities being transferred in violation of the Securities Act or any applicable securities law and (B) such amendment does not materially and adversely affect the rights of holders to transfer debt securities;



x.

change or eliminate any of the provisions of the indenture; provided that any such change or elimination shall become effective only when there is no outstanding debt security of any series created prior to the execution of such supplemental indenture that is entitled to the benefit of such provision and as to which such supplemental indenture would apply;



xi.

make any amendment to the indenture necessary to qualify the indenture under the Trust Indenture Act;

        The consent of the holders is not necessary under the indenture to approve the particular form of any proposed amendment, supplement or waiver. It is sufficient if such consent approves the substance of the proposed amendment or supplement. A consent to any amendment, supplement or waiver under the indenture by any holder given in connection with a tender of such holder's debt securities will not be rendered invalid by such tender. After an amendment, supplement or waiver under the indenture becomes effective, we are required to give to the holders a notice briefly describing such amendment, supplement or waiver. However, the failure to give such notice to all the holders, or any defect in the notice will not impair or affect the validity of the amendment, supplement or waiver.

Consolidation, Merger and Sale of Assets

        The indenture provides that we may not consolidate with or merge into any other Person in a transaction in which we are not the surviving entity, or convey, transfer or lease our properties and assets substantially as an entirety to, any Person unless:

i.

any Person formed by such consolidation or into which we are merged or to whom we have conveyed, transferred or leased our properties and assets substantially as an entirety is a corporation, partnership, trust or other entity validly existing under the laws of the British Virgin Islands, the Cayman Islands or Hong Kong and such Person expressly assumes by indentures supplemental to the indenture all of our obligations under the indenture and the debt securities issued under the indenture, including the obligation to pay Additional Amounts with respect to any jurisdiction in which it is organized or resident for tax purposes;

14

ii.

immediately after giving effect to the transaction, no Event of Default, and no event which, after notice or lapse of time or both, would become an Event of Default, shall have occurred and be continuing; and



iii.

we have delivered to the trustee an officers' certificate and an opinion of independent legal counsel, each stating that such consolidation, merger, conveyance, transfer or lease and such supplemental indentures comply with the indenture and that all conditions precedent therein provided for relating to such transaction have been complied with.

Payments for Consent

        We will not, and will not permit any of our Controlled Entities to, directly or indirectly, pay or cause to be paid any consideration to or for the benefit of any holder of debt securities of any series for or as an inducement to any consent, waiver or amendment of any of the terms or provisions of the indenture or the debt securities of such series unless such consideration is offered to be paid and is paid to all holders of the relevant series of debt securities that consent, waive or agree to amend in the time frame set forth in the solicitation documents relating to such consent, waiver or amendment.

        However, a default under clause (iv) of the preceding paragraph will not constitute an Event of Default until the trustee or the holders of 25% in principal amount of the then outstanding debt securities of such series provide written notice to us of the default and we do not cure such default within the time specified in clause (iv) of the preceding paragraph after receipt of such written notice.

        The trustee shall not be deemed to have notice of any Default or Event of Default (other than a payment default) unless a written notice of any event which is in fact such a default is received by a

16

responsible officer of the Trustee, with direct responsibility for the administration of the Indenture, at the Corporate Trust Office of the Trustee, and such notice references the Notes and the Indenture.

        If an Event of Default (other than an Event of Default described in clauses (vii) or (viii) above) shall occur and be continuing, either the trustee or the holders of at least 25% in aggregate principal amount of the debt securities of that series then outstanding by written notice as provided in the indenture may, and the trustee, upon instructions from holders of at least 25% in aggregate principal amount of the debt securities of that series then outstanding and subject to receipt of pre-funding, security and/or indemnity to its satisfaction, shall declare the unpaid principal amount of the debt securities of that series and any accrued and unpaid interest thereon (and any Additional Amount payable in respect thereof) to be due and payable immediately upon receipt of such notice. If an Event of Default described in clause (v) above shall occur, the declaration of acceleration of the debt securities shall be automatically annulled if the default triggering such Event of Default pursuant to clause (v) shall be remedied or cured by us or any of our Principal Controlled Entities or waived by the holders of the relevant indebtedness within 30 days after the declaration of acceleration with respect thereto and if (1) the annulment of the acceleration of the debt securities of that series would not conflict with any judgment or decree of a court of competent jurisdiction and (2) all Events of Default, other than the non-payment of principal, premium (if any) or interest on the debt securities of that series that became due solely because of the acceleration of the debt securities of that series, have been cured or waived. If an Event of Default described in clauses (vii) or (viii) above shall occur, the unpaid principal amount of all the debt securities then outstanding and any accrued and unpaid interest thereon will automatically, and without any declaration or other action by the trustee or any holder of such debt securities, become immediately due and payable. After a declaration of acceleration but before a judgment or decree for payment of the money due has been obtained by the trustee, the holders of at least a majority in aggregate principal amount of the debt securities of that series then outstanding may, under certain circumstances, waive all past defaults and rescind and annul such acceleration if (1) rescission would not conflict with any judgment or decree of a court of competent jurisdiction and (2) all Events of Default, other than the non-payment of principal, premium, if any, or interest on such debt securities that became due solely because of the acceleration of such debt securities, have been cured or waived . For information as to waiver of defaults, see "—Modification and Waiver."

        Subject to the provisions of the indenture relating to the duties of the trustee, in case an Event of Default shall occur and be continuing, the trustee will be under no obligation to exercise any of the trusts or powers vested in it by the indenture at the request, order or direction of any of the holders of such debt securities, unless such holders shall have offered to the trustee pre-funding, security and/or indemnity satisfactory to it against the costs, expenses and liabilities which may be incurred therein or thereby. Subject to certain provisions, including those requiring pre-funding, security and/or indemnification of the trustee, the holders of a majority in aggregate principal amount of the debt securities of a series then outstanding will have the right to direct the time, method and place of conducting any proceeding for any remedy available to the trustee or exercising any trust or power conferred on the trustee. No holder of any debt securities of any series will have any right to institute any proceeding, judicial or otherwise, with respect to the indenture or the debt securities, or for the appointment of a receiver or a trustee, or for any other remedy thereunder, unless (i) such holder has previously given to the trustee written notice of a continuing Event of Default with respect to the debt securities of that series, (ii) the holders of at least 25% in aggregate principal amount of the debt securities of that series then outstanding have made written request to the trustee to institute such proceeding, (iii) such holder or holders have offered pre-funding, security and/or indemnity satisfactory to the trustee and (iv) the trustee has failed to institute such proceeding, and has not received from the holders of a majority in aggregate principal amount of the debt securities of that series then outstanding a written direction inconsistent with such request, within 60 days after such notice, request and offer. However, such limitations do not apply to a suit instituted by a holder of a debt security for

17

the enforcement of the right to receive payment of the principal of, premium (if any) or interest on such debt security on or after the applicable due date specified in such debt security.

Legal Defeasance and Covenant Defeasance

        The indenture will provide that we may at our option and at any time elect to have all of our obligations discharged with respect to the outstanding debt securities of a series ("Legal Defeasance") except for:

1)

the rights of holders of the debt securities of that series that are then outstanding to receive payments in respect of the principal of, or interest or premium on such debt securities when such payments are due from the trust referred to below;



2)

our obligations with respect to the debt securities of that series concerning issuing temporary notes, registration of notes, mutilated, destroyed, lost or stolen notes and the maintenance of an office or agency for payment and money for security payments held in trust;

the rights, powers, trusts, duties and immunities of the trustee for the debt securities of that series, and our obligations in connection therewith; and



4)

the Legal Defeasance and Covenant Defeasance (as defined below) provisions of the indenture for the debt securities of that series.

        The indenture will provide that, we may, at our option and at any time, elect to have our obligations with respect to the outstanding debt securities of a series released with respect to certain covenants (including our obligations under the headings "Consolidation, Merger and Sale of Assets" and "Payments for Consents") that are described in the indenture ("Covenant Defeasance") and thereafter any omission to comply with those covenants will not constitute a Default or Event of Default. In the event Covenant Defeasance occurs, certain events (not including non-payment, bankruptcy, receivership, rehabilitation and insolvency events) described under the caption "—Events of Default" will no longer constitute an Event of Default.

        The indenture will also provide that, in order to exercise either Legal Defeasance or Covenant Defeasance:

1)

we must irrevocably deposit with the trustee, in trust, for the benefit of the holders of all debt securities of that series subject to Legal Defeasance or Covenant Defeasance, cash in U.S. dollars, U.S. Government Obligation, or a combination of cash in U.S. dollars and U.S. Government Obligation, in amounts as will be sufficient, in the opinion of a nationally recognized investment bank, appraisal firm or firm of independent public accountants to pay the principal of, or interest and premium on such notes that are then outstanding on the Stated Maturity or on the applicable redemption date, as the case may be, and we must specify whether such debt securities are being defeased to maturity or to a particular redemption date;



2)

in the case of Legal Defeasance, we must deliver to the trustee an opinion of independent legal counsel reasonably acceptable to the trustee confirming that (a) we have received from, or there has been published by, the Internal Revenue Service a ruling or (b) since the date of the indenture, there has been a change in the applicable federal income tax law, in either case to the effect that, and based thereon such opinion of independent legal counsel will confirm that, the beneficial owners of the then outstanding debt securities of that series will not recognize income, gain or loss for federal income tax purposes as a result of such Legal Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Legal Defeasance had not occurred;

18

3)

in the case of Covenant Defeasance, we must deliver to the trustee an opinion of independent legal counsel reasonably acceptable to the trustee confirming that the beneficial owners of the then outstanding debt securities of that series will not recognize income, gain or loss for federal income tax purposes as a result of such Covenant Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred;



4)

no Default or Event of Default with respect to the debt securities of that series must have occurred and be continuing on the date of such deposit (other than a Default or Event of Default resulting from the borrowing of funds to be applied to such deposit);



5)

we must deliver to the trustee an officers' certificate stating that the deposit was not made by us with the intent of preferring the holders of debt securities of that series over our other creditors with the intent of defeating, hindering, delaying or defrauding our creditors or others; and



6)

we must deliver to the trustee an officers' certificate and an opinion of independent legal counsel, each stating that all conditions precedent relating to the Legal Defeasance or the Covenant Defeasance have been complied with.

Satisfaction and Discharge

        The indenture will be discharged and will cease to be of further effect with respect to debt securities of a series when:

1)

either:



a)

all debt securities of that series that have been authenticated, except lost, stolen or destroyed debt securities that have been replaced or paid and notes for whose payment money has been deposited in trust and thereafter repaid to us, have been delivered to the trustee for cancellation; or



b)

all debt securities of that series that have not been delivered to the trustee for cancellation have become due and payable by reason of the mailing of a notice of redemption or otherwise or will become due and payable within one year and we have irrevocably deposited or caused to be deposited with the trustee as trust funds in trust solely for the benefit of the holders of the debt securities of such series, cash in U.S. dollars, U.S. Government Obligation, or a combination of cash in U.S. dollars and U.S. Government Obligation, in amounts as will be sufficient, without consideration of any reinvestment of interest, to pay and discharge the entire indebtedness on such debt securities not delivered to the trustee for cancellation for principal, premium and accrued interest to the date of maturity or redemption;



2)

no Default or Event of Default under the indenture has occurred and is continuing with respect to the debt securities of that series on the date of the deposit (other than a Default or Event of Default resulting from the borrowing of funds to be applied to such deposit) and the deposit will not result in a breach or violation of, or constitute a default under, any other instrument to which we are a party or by which we are bound;



3)

we have paid or caused to be paid all sums payable by us under the indenture with respect to the debt securities of that series; and



4)

we have delivered irrevocable instructions to the trustee under the indenture to apply the deposited money toward the payment of the debt securities of that series at maturity or the redemption date, as the case may be.

19

        In addition, we must deliver an officers' certificate and an opinion of independent legal counsel to the trustee stating that all conditions precedent to satisfaction and discharge have been satisfied.

Concerning the Trustee

        The trustee under the indenture is Deutsche Bank Trust Company Americas. Pursuant to the indenture, the trustee will be designated by us as the initial paying and transfer agent and registrar for the debt securities. The corporate trust office of the trustee is currently located at 60 Wall Street, 16th Floor, New York, New York 10005, United States, Attention: Corporates Team Deal Manager-Weibo Corporation.

        The indenture provides that the trustee, except during the continuance of an Event of Default, undertakes to perform such duties and only such duties as are specifically set forth therein. If an Event of Default has occurred and is continuing, the trustee will exercise such of the rights and powers vested in it by the indenture, and use the same degree of care and skill in its exercise, as a prudent person would exercise or use under the circumstances in the conduct of such person's own affairs.

        The trustee in its various capacities assumes no responsibility for the accuracy or completeness of the information concerning the Company or its affiliates or any other party referenced in this prospectus or any prospectus supplement or for any failure by the Company or any other party to disclose events that may have occurred and may affect the significance or accuracy of such information.

        Whenever the trustee shall have discretion or permissive power in accordance with the indenture or the law, the trustee may decline to exercise the same in the absence of approval by the holders and shall have no obligation to exercise the same unless it has received pre-funding, been indemnified and/or provided with security to its satisfaction against all actions, proceedings, claims, actions or demands to which it may render itself liable and all costs, damages, charges, expenses and liabilities which it may incur by so doing. The trustee in its various capacities shall in no event be responsible for consequential loss or damage of any kind whatsoever (including, but not limited to, loss of profit).

        Subject to the terms of the indenture and the Trust Indenture Act, the trustee is permitted to engage in other transactions with the Company and its affiliates and can profit therefrom without being obliged to account for such profit; and the trustee shall not be under any obligation to monitor any conflict of interest, if any, which may arise between itself and such other parties. The trustee may have interest in, or may be providing, or may in the future provide financial services to other parties.

Currency Indemnity

        To the fullest extent permitted by law, our obligations to any holder of debt securities under the indenture or the applicable series of debt securities, as the case may be, shall, notwithstanding any judgment in a currency (the "Judgment Currency") other than U.S. dollars (the "Agreement Currency"), be discharged only to the extent that on the Business Day following receipt by such holder or the trustee, as the case may be, of any amount in the Judgment Currency, such holder or the trustee, as the case may be, may in accordance with normal banking procedures purchase the Agreement Currency with the Judgment Currency. If the amount of the Agreement Currency so purchased is less than the amount originally to be paid to such holder or the trustee, as the case may be, in the Agreement Currency, we agree, as a separate obligation and notwithstanding such judgment, to pay the difference and if the amount of the Agreement Currency so purchased exceeds the amount originally to be paid to such holder, such holder or the trustee, as the case may be, agrees to pay to or for our account such excess, provided that such holder shall not have any obligation to pay any such excess as long as a default by us in our obligations under the indenture or the debt securities of such series has occurred and is continuing, in which case such excess may be applied by such holder to such obligations.

23

LEGAL OWNERSHIP OF DEBT SECURITIES

        In this prospectus and the applicable prospectus supplement, when we refer to the "holders" of debt securities as being entitled to specified rights or payments, we mean only the actual legal holders of the debt securities. While you will be the holder if you hold a security registered in your name, more often than not the registered holder will actually be a broker, bank, other financial institution or, in the case of a global security, a depositary. Our obligations, as well as the obligations of the trustee, any registrar, any depositary, and any third parties employed by us or the other entities listed above, run only to persons who are registered as holders of our debt securities, except as may be specifically provided for in a contract governing the debt securities. For example, once we make payment to the registered holder, we have no further responsibility for the payment even if that registered holder is legally required to pass the payment along to you as a street name customer but does not do so.

Street Name and Other Indirect Holders

        Holding debt securities in accounts at banks or brokers is called holding in "street name." If you hold our debt securities in street name, we will recognize only the bank or broker, or the financial institution that the bank or broker uses to hold the debt securities, as a holder. These intermediary banks, brokers, other financial institutions, and depositaries pass along principal, interest, dividends, and other payments, if any, on the debt securities, either because they agree to do so in their customer agreements or because they are legally required to do so. This means that if you are an indirect holder, you will need to coordinate with the institution through which you hold your interest in a security in order to determine how the provisions involving holders described in this prospectus and any prospectus supplement will actually apply to you. For example, if the debt security in which you hold a beneficial interest in street name can be repaid at the option of the holder, you cannot redeem it yourself by following the procedures described in the prospectus supplement relating to that security. Instead, you would need to cause the institution through which you hold your interest to take those actions on your behalf. Your institution may have procedures and deadlines different from or additional to those described in the applicable prospectus supplement.

        If you hold our debt securities in street name or through other indirect means, you should check with the institution through which you hold your interest in a security to find out, among others:

•

how it handles payments and notices with respect to the debt securities;

•

whether it imposes fees or charges;

•

how it handles voting, if applicable;

•

how and when you should notify it to exercise on your behalf any rights or options that may exist under the debt securities;

•

whether and how you can instruct it to send you debt securities registered in your own name so you can be a direct holder; and

•

how it would pursue rights under the debt securities if there were a default or other event triggering the need for holders to act to protect their interests.

Global Securities

        A global security is a special type of indirectly held security. If we issue debt securities in the form of global securities, the ultimate beneficial owners can only be indirect holders. We do this by requiring that the global security be registered in the name of a financial institution we select and by requiring that the debt securities included in the global security not be transferred to the name of any other direct holder unless the special circumstances described below occur. The financial institution that acts as the sole direct holder of the global security is called the "depositary." Any person wishing to own a

24

security issued in global form must do so indirectly through an account with a broker, bank, or other financial institution that in turn has an account with the depositary. The applicable prospectus supplement will indicate whether the debt securities will be issued only as global securities.

        As an indirect holder, your rights relating to a global security will be governed by the account rules of your financial institution and of the depositary, as well as general laws relating to securities transfers. We will not recognize you as a holder of the debt securities and instead will deal only with the depositary that holds the global security.

        You should be aware that if our debt securities are issued only in the form of global securities:

•

you cannot have the debt securities registered in your own name;

•

you cannot receive physical certificates for your interest in the debt securities;

•

you will be a street name holder and must look to your own bank or broker for payments on the debt securities and protection of your legal rights relating to the debt securities;

•

you may not be able to sell interests in the debt securities to some insurance companies and other institutions that are required by law to own their debt securities in the form of physical certificates;

•

the depositary's policies will govern payments, dividends, transfers, exchange and other matters relating to your interest in the global security. We, the trustee, and any registrar have no responsibility for any aspect of the depositary's actions or for its records of ownership interests in the global security. We, the trustee and any registrar also do not supervise the depositary in any way; and

•

the depositary will require that interests in a global security be purchased or sold within its system using same-day funds for settlement.

        In a few special situations described below, a global security representing our debt securities will terminate and interests in it will be exchanged for physical certificates representing the debt securities. After that exchange, the choice of whether to hold debt securities directly or in street name will be up to you. You must consult your bank or broker to find out how to have your interests in the debt securities transferred to your name, so that you will be a direct holder.

        Unless we specify otherwise in the applicable prospectus supplement, the special situations for termination of a global security representing our debt securities are:

•

the depositary has notified us that it is unwilling or unable to continue as depositary for such global security or the depositary ceases to be a clearing agency registered under the Securities Exchange Act of 1934, as amended, at a time when such depositary is required to be so registered in order to act as depositary, and, in each case, we do not or cannot appoint a successor depositary within 90 days;

•

we decide in our sole discretion to allow some or all book-entry securities to be exchangeable for definitive securities in registered form; or

•

upon request by holders, in case that an event of default with respect to the debt securities of the applicable series has occurred and is continuing.

        The applicable prospectus supplement may also list additional situations for terminating a global security that would apply only to the particular series of debt securities covered by such prospectus supplement. When a global security terminates, the depositary (and not us, the trustee or any registrar) is responsible for deciding the names of the institutions that will be the initial direct holders.

ENFORCEABILITY OF CIVIL LIABILITIES

        We are incorporated in the Cayman Islands because of the following benefits found there:

•

political and economic stability;

•

an effective judicial system;

•

a favorable tax system;

•

the absence of exchange control or currency restrictions; and

•

the availability of professional and support services.

        However, certain disadvantages accompany incorporation in the Cayman Islands. These disadvantages include:

•

the Cayman Islands has a less developed body of securities laws as compared to the United States and these securities laws provide significantly less protection to investors; and

•

Cayman Islands companies may not have standing to sue before the federal courts of the United States.

        Our constituent documents do not contain provisions requiring that disputes, including those arising under the securities laws of the United States, between us, our officers, directors and shareholders, be arbitrated.

        Substantially all of our current operations are conducted in China, and substantially all of our assets are located in China. We have appointed Puglisi & Associates, which is located at 850 Library Avenue, Suite 204, Newark, DE 19711, as our agent upon whom process may be served in any action brought against us under the securities laws of the United States. A majority of our directors and officers are nationals or residents of jurisdictions other than the United States and a substantial portion of their assets are located outside the United States. As a result, it may be difficult for an investor to effect service of process within the United States upon these persons, or to enforce against us or them judgments obtained in United States courts, including judgments predicated upon the civil liability provisions of the securities laws of the United States or any state in the United States.

        Maples and Calder (Hong Kong) LLP, our counsel as to Cayman Islands law, and TransAsia Lawyers, our counsel as to PRC law, have advised us that there is uncertainty as to whether the courts of the Cayman Islands and China, respectively, would:

•

recognize or enforce judgments of United States courts obtained against us or our directors or officers predicated upon the civil liability provisions of the securities laws of the United States or any state in the United States; or

•

entertain original actions brought in each respective jurisdiction against us or our directors or officers predicated upon the securities laws of the United States or any state in the United States.

        Maples and Calder (Hong Kong) LLP has advised us that although there is no statutory recognition in the Cayman Islands of judgments obtained in the United States, the courts of the Cayman Islands will in the circumstances described below, recognize and enforce a non-penal judgment of a foreign court of competent jurisdiction without retrial on the merits. While there is no binding authority on this point, this is likely to include, in certain circumstances, a non-penal judgment of a United States court imposing a monetary award based on the civil liability provisions of the U.S. federal securities laws.

        Maples and Calder (Hong Kong) LLP has further advised us that a judgment obtained in the United States will be recognized and enforced in the courts of the Cayman Islands at common law,

26

without any re-examination of the merits of the underlying dispute, by an action commenced on the foreign judgment debt in the Grand Court of the Cayman Islands, provided such judgment (i) is given by a foreign court of competent jurisdiction; (ii) imposes on the judgment debtor a liability to pay a liquidated sum for which the judgment has been given; (iii) is final; (iv) is not in respect of taxes, a fine or a penalty; and (v) was not obtained in a manner and is not of a kind the enforcement of which is contrary to natural justice or the public policy of the Cayman Islands. The Grand Court of the Cayman Islands may stay proceedings if concurrent proceedings are being brought elsewhere. Neither the United States or China has a treaty with the Cayman Islands providing for reciprocal recognition and enforcement of judgments of courts of the United States or China, respectively, in civil and commercial matters.

        TransAsia Lawyers has further advised us that the recognition and enforcement of foreign judgments are provided for under the PRC Civil Procedures Law. PRC courts may recognize and enforce foreign judgments in accordance with the requirements of the PRC Civil Procedures Law based either on treaties between China and the country where the judgment is made or on principles of reciprocity between jurisdictions. China does not have any treaties or other form of reciprocity with the United States that provide for the reciprocal recognition and enforcement of foreign judgments. In addition, according to the PRC Civil Procedures Law, PRC courts will not enforce a foreign judgment against us or our directors and officers if they decide that the judgment violates the basic principles of PRC law or national sovereignty, security or public interest. As a result, it is uncertain whether and on what basis a PRC court would enforce a judgment rendered by a court in the United States.

27

Unless we otherwise state in the applicable prospectus supplement, various conditions will apply to the underwriters' obligation to purchase securities, and the underwriters will be obligated to purchase all of the securities contemplated in an offering if they purchase any of such securities. Any initial public offering price and any discounts or concessions allowed or reallowed or paid to dealers may be changed from time to time. The underwriter or underwriters with respect to a particular underwritten offering of securities, or, if an underwriting syndicate is used, the managing underwriter or underwriters, will be set forth on the cover of the applicable prospectus supplement.

28

        If we use dealers in the sale, unless we otherwise indicate in the applicable prospectus supplement, we will sell securities to the dealers as principals. The dealers may then resell the securities to the public at varying prices that the dealers may determine at the time of resale.

Direct Sales

        We may also sell securities directly without using agents, underwriters, or dealers.

General Information

        We may enter into agreements with underwriters, dealers, and agents that entitle them to indemnification against certain civil liabilities, including liabilities under the Securities Act, or to contribution with respect to payments which the underwriters, dealers, or agents may be required to make. Underwriters, dealers, and agents may be customers of, may engage in transactions with, or perform services for, us or our subsidiaries in the ordinary course of business.

        Underwriters, dealers, and agents that participate in the distribution of the securities may be underwriters as defined in the Securities Act, and any discounts or commissions received by them from us and any profit on the resale of the securities by them may be treated as underwriting discounts and commissions under the Securities Act. Any underwriters, dealers, or agents used in the offer or sale of securities will be identified and their compensation described in an applicable prospectus supplement.

29

PART II

INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 8.    INDEMNIFICATION OF DIRECTORS AND OFFICERS

        Cayman Islands law does not limit the extent to which a company's articles of association may provide for indemnification of officers and directors, except to the extent any such provision may be held by the Cayman Islands courts to be contrary to public policy, such as to provide indemnification against civil fraud or the consequences of committing a crime. Our articles of association provide for indemnification of officers and directors from and against all actions, proceedings, costs, charges, losses, damages, and expenses that they may incur by reason of any act done, concurred in, or omitted in the execution of their duty, or supposed duty, in their respective offices, provided that such indemnity will not extend to any matter in respect of any fraud or dishonesty that may attach to any of the officers or directors.

        The form of Underwriting Agreement to be filed as Exhibit 1.1 to this registration statement will also provide for indemnification of us and our officers and directors.

        Pursuant to the indemnification agreements between us and our directors and officers, the form of which was filed as Exhibit 10.3 to our registration statement on Form F-1 (File No. 333-194589) that was filed with the SEC on March 14, 2014, we agreed to indemnify our directors and officers against certain liabilities and expenses incurred by such persons in connection with claims made by reason of their being a director or officer.

         (ii)  Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5) or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii) or (x) for the purpose of providing the information required by section 10(a) of the Securities Act shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which that prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof; provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date.

        (6)   That, for the purpose of determining liability of the registrant under the Securities Act to any purchaser in the initial distribution of the securities, the undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications,

II-2

the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

          (i)  Any preliminary prospectus or prospectus of the undersigned Registrant relating to the offering required to be filed pursuant to Rule 424;

         (ii)  Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;

        (iii)  The portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and

        (iv)  Any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

        (b)   The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the registrant's annual report pursuant to Section 13(a) or Section 15(d) of the Exchange Act that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

        (c)   Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act, as amended, and will be governed by the final adjudication of such issue.
