On June 23, 2015, Yan Tang, Matrix Partners China II Hong Kong Limited (“Matrix”), Sequoia Capital China Investment Management L.P. and Huatai Ruilian Fund Management Co., Ltd. (Huatai Ruilian, and collectively, the “Buyer Group”) jointly submitted a non-binding proposal (the “Proposal”) to the Issuer’s board of directors related to the proposed acquisition of all of the Ordinary Shares not beneficially owned by the Buyer Group for cash consideration equal to US$18.90 per ADS, or US$9.45 per Class A Ordinary Share (the “Proposed Transaction”).

The Proposed Transaction is subject to a number of conditions, including, among other things, the negotiation and execution of a definitive merger agreement and other related agreements mutually acceptable in form and substance to the Issuer and the Buyer Group. Neither the Issuer nor any member of the Buyer Group is obligated to complete the Proposed Transaction, and a binding commitment with respect to the Proposed Transaction will result only from the execution of definitive documents, and then will be on the terms provided in such documentation.

On July 6, 2015, the Buyer Group entered into a consortium agreement (the “Consortium Agreement”), pursuant to which the Buyer Group will cooperate in connection with a possible acquisition transaction (the “Transaction”) with respect to the Issuer as contemplated by the Proposal. The Consortium Agreement provides, among other things, for: cooperation in arranging financing; engaging advisors; and cooperation in preparing definitive documentation with respect to the Transaction. During the period beginning on the date of the Consortium Agreement and ending on the earlier of (i) 9-month after the date of the Consortium Agreement and (ii) the termination of the Consortium Agreement on the mutual written agreement of the members of the Buyer Group, members of the Buyer Group have agreed to work exclusively with each other with respect to the Transaction.

If the Proposed Transaction is completed, the Issuer’s ADSs would become eligible for termination of registration pursuant to Section 12(g)(4) of the Securities Act and would be delisted from the NASDAQ Global Select Market.

The place of arbitration shall be Hong Kong. The official language of the arbitration shall be English and the tribunal shall consist of three arbitrators (each, an “Arbitrator”). The claimant(s), irrespective of number, shall nominate jointly one Arbitrator; the respondent(s), irrespective of number, shall nominate jointly one Arbitrator; and a third Arbitrator will be nominated jointly by the first two Arbitrators and shall serve as chairman of the tribunal. In the event the claimant(s) or respondent(s) or the first two Arbitrators shall fail to nominate or agree the joint nomination of an Arbitrator or the third Arbitrator within the time limits specified by the Rules, such Arbitrator shall be appointed promptly by the HKIAC. The tribunal shall have no authority to award punitive or other punitive-type damages. The award of the arbitration tribunal shall be final and binding upon the disputing parties. Any party to an award may apply to any court of competent jurisdiction for enforcement of such award and, for purposes of the enforcement of such award, the Parties irrevocably and unconditionally submit to the jurisdiction of any court of competent jurisdiction and waive any defenses to such enforcement based on lack of personal jurisdiction or inconvenient forum.

Notwithstanding the foregoing, the Parties hereby consent to and agree that in addition to any recourse to arbitration as set out in this Section 6, any Party may, to the extent permitted under the laws of the jurisdiction where application is made, seek an interim injunction from a court or other authority with competent jurisdiction and, notwithstanding that this Agreement is governed by the laws of the State of New York, a court or authority hearing an application for injunctive relief may apply the procedural law of the jurisdiction where the court or other authority is located in determining whether to grant the interim injunction. For the avoidance of doubt, this Section 6(b) is only applicable to the seeking of interim injunctions and does not restrict the application of Section 6(a) in any way.

Dear Sirs:

Mr. Yan Tang (“Mr. Tang”), co-founder, chairman and chief executive officer of Momo Inc. (the “Company”), Matrix Partners China II Hong Kong Limited (“Matrix”), Sequoia Capital China Investment Management L.P. (“Sequoia”) and Huatai Ruilian Fund Management Co., Ltd. (“Huatai Ruilian”, and together with Mr. Tang, Matrix and Sequoia, the “Buyer Group”), are pleased to submit this preliminary non-binding proposal to acquire all outstanding ordinary shares (the “Shares”) of the Company not owned by the Buyer Group in a going-private transaction (the “Acquisition”). Our proposed purchase price is US$18.90 per American depositary share of the Company (“ADS”, each representing two Shares) in cash. The Buyer Group and their affiliates beneficially own approximately 47.8% of all the issued and outstanding Shares of the Company, which represent approximately 84.1% of the aggregate voting power of the Company.

We believe that our proposed price provides an attractive opportunity to the Company’s shareholders. This price represents a premium of 20.5% above the closing trading price of the Company’s ADS on June 22, 2015, the last trading day prior to the date hereof.

The terms and conditions upon which we are prepared to pursue the Acquisition are set forth below. We are confident in our ability to consummate an Acquisition as outlined in this letter.

In closing, each of us would like to express our commitment to working together to bring this Acquisition to a successful and timely conclusion. Should you have any questions regarding this proposal, please do not hesitate to contact any of us. We look forward to speaking with you.
