Pursuant to a Share Subscription Agreement dated January 19, 2006, SCC I purchased 12,001,217 Series A Preferred Shares of the Issuer for an aggregate consideration of $6,000,000. 1,086,110 of these Series A Preferred Shares were transferred to SCC PTRS I on February 27, 2006, and 1,462,948 of these Series A Preferred Shares were transferred to SCC PRIN I on May 17, 2006. Additionally, pursuant to a Warrant to Purchase Series A Preferred Shares dated May 16, 2006, SCC I received a warrant to purchase 685,851 fully paid and nonassessable Series A Preferred Shares of the Issuer at a share purchase price of $0.4999 per share. A warrant to purchase 83,605 of these Series A Preferred Shares was transferred to SCC PRIN I on May 16, 2006. A warrant to purchase 62,070 of these Series A Preferred Shares was transferred to SCC PTRS I on May 16, 2006.

Each Series B Preferred Share was convertible into one Ordinary Share of the Issuer. All of the 14,202,219 Series A and Series B Preferred Shares were converted into14,202,219 Ordinary Shares in connection with the closing of the Issuer’s initial public offering. Additionally, in connection with the closing of the Issuer’s initial public offering, and pursuant to a Subscription Agreement dated March 14, 2011, SCC I purchased 407,379 Ordinary Shares for an aggregate consideration of $3,938,000, SCC PTRS I purchased 46,810 Ordinary Shares for an aggregate consideration of $452,500 and SCC PRIN I purchased 63,052 Ordinary Shares of the Issuer for an aggregate consideration of $609,500.

In connection with those distributions, each of SCC UR and NS received their pro rata portion of such distributions, including the 760,351 Ordinary Shares reported herein as beneficially owned.

ITEM 4.

PURPOSE OF TRANSACTION.

On June 17, 2015, Mr. Hongyi Zhou (the “Chairman”), CITIC Securities Co. Ltd. (“CITIC”), Golden Brick Capital Private Equity Fund I L.P. (“Golden Brick”), China Renaissance Holdings Limited (“China Renaissance”) and Sequoia Capital China I, L.P. (collectively, the “Sequoia Funds” and together with CITIC, Golden Brick, China Renaissance and the Chairman, the “Consortium”) submitted a preliminary, non-binding letter (the “Proposal Letter”) to the Board of Directors of the Issuer (the “Board”). In the Proposal Letter, the Consortium outlined its proposal (“Proposal”) for a going-private transaction (the “Transaction”). Under the Proposal, members of the Consortium or their affiliates propose to acquire all of the outstanding share capital of the Issuer (other than those shares beneficially owned by the members of the Consortium or their affiliates (the “Shareholder Shares”), which will be rolled over in connection with the Transaction, and any other shares that will be rolled over in connection with the Transaction) for US$77.00 in cash per American Depositary Share of the Issuer (“ADS,” with each two ADSs representing three Class A Ordinary Shares), or $51.33 in cash per Class A and Class B Ordinary Share, as the case may be. In the Proposal Letter, the Consortium stated that it has held discussions with financial institutions that have expressed interests in providing financing in connection with the Transaction. The Proposal also provides that, among other things, (a) the Consortium’s financing sources will need to conduct customary due diligence on the Issuer, and (b) the Consortium will negotiate with the Issuer to agree on, and enter into, definitive agreements with respect to the Transaction.

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

References to the Proposal Letter in this Schedule 13D are qualified in their entirety by reference to the Proposal Letter, which is attached hereto as an exhibit and incorporated herein by reference as if set forth in its entirety herein.

If the proposed Transaction is completed, the ADSs would be delisted from the New York Stock Exchange, and the Issuer’s obligation to file periodic reports under the Securities Exchange Act of 1934, as amended, would terminate. In addition, consummation of the Proposed Transaction could result in one or more of the actions specified in clauses (a)-(j) of Item 4 of Schedule 13D, including the acquisition or disposition of securities of the Issuer, a merger or other extraordinary transaction involving the Issuer, a change to the Board (as the surviving company in the merger), and a change in the Issuer’s memorandum and articles of association to reflect that the Issuer would become a privately held company.

ITEM 5.

The information set forth and/or incorporated by reference in Items 2, 3 and 4 is hereby incorporated by reference into this Item 5.

(a) The aggregate number of Ordinary Shares and the percentage of total outstanding Ordinary Shares beneficially owned by the Reporting Persons is set forth below. References to percentage ownerships of Ordinary Shares are based upon 147,485,168 Class A Ordinary Shares outstanding as of December 31, 2014 as reported by the Issuer in its Form 20-F dated April 27, 2015. Pursuant to Rule 13d-3 of the Act, the Reporting Persons may be deemed to beneficially own 760,351 Class A Ordinary Shares of the Issuer, representing 0.5% of the outstanding Class A Ordinary Shares of the Issuer. The filing of this Statement shall not be construed as an admission that a Reporting Person beneficially owns those shares held by any other Reporting Person.

NS , who wholly owns and is the sole director of SCC UR, may be deemed to beneficially own an aggregate of 760,351 Ordinary Shares, which represents 0.5% of the outstanding Class A Ordinary Shares calculated in accordance with the requirements of Rule 13d-3 under the Act.

The Reporting Persons may be deemed to be a “group” with the Chairman, CITIC, Golden Brick and China Renaissance for purposes of Section 13(d) of the Act as a result of the submission of the Proposal Letter (as defined in Item 4). However, each of the Reporting Persons expressly disclaims beneficial ownership for all purposes of the Class A Ordinary Shares and Class B Ordinary Shares and ADSs held by the Chairman, CITIC, Golden Brick and China Renaissance or any other Consortium member. The Reporting Persons are only responsible for the information contained in this Schedule 13D and assume no responsibility for information contained in any other Schedules 13D filed by the Chairman, CITIC, Golden Brick or China Renaissance. In addition, the filing of this Schedule 13D shall not be construed as an admission that the Reporting Persons themselves are a group, or have agreed to act as a group. Each Reporting Person expressly disclaims beneficial ownership of the securities reported herein except to the extent such Reporting Person actually exercises voting or dispositive power with respect to such securities.

(b) The number of Ordinary Shares as to which each of the Reporting Persons has sole or shared power to vote, direct the vote, dispose or direct the disposition are as set forth in rows seven through ten of the cover pages hereof. The information set forth in Item 2 is hereby incorporated by reference into this Item 5(b).

(c) To the best knowledge of each of the Reporting Persons, none of the Reporting Persons has effected any transactions relating to the Ordinary Shares during the past 60 days, except that NS sold 180,000 Ordinary Shares, in the form of 120,000 ADSs, on June 22, 2015 for an aggregate consideration of $8,646,000.

(d) To the best knowledge of the Reporting Persons, no person other than the Reporting Persons has the right to receive or the power to direct the receipt of dividends from, or the proceeds from the sale of, the securities beneficially owned by the Reporting Persons identified in this Item 5.

(e) Not applicable.

ITEM 6.

CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH RESPECT TO SECURITIES OF THE ISSUER.

The information set forth and/or incorporated by reference in Items 2, 3, 4 and 5 is hereby incorporated by reference into this Item 6.

To the best knowledge of the Reporting Persons, except as set forth herein, there are no contracts, arrangements, understandings or relationships (legal or otherwise), including, but not limited to, transfer or voting of any of the securities, finder’s fees, joint ventures, loan or option arrangements, puts or calls, guarantees of profits, division of profits or loss, or the giving or withholding of proxies, between the persons enumerated in Item 2, and any other person, with respect to any securities of the Issuer, including any securities pledged or otherwise subject to a contingency the occurrence of which would give another person voting power or investment power over such securities other than standard default and similar provisions contained in loan agreements.

The Board of Directors

Qihoo 360 Technology Co. Ltd.

Building No. 2

6 Jiuxianqiao Road, Chaoyang District

Beijing 100015

People’s Republic of China

Dear Members of the Board of Directors,

We, Hongyi Zhou, chairman and chief executive officer of Qihoo 360 Technology Co. Ltd. (the “Company”), CITIC Securities Co. Ltd. or its affiliates, Golden Brick Capital Private Equity Fund I L.P., China Renaissance Holdings Limited or its affiliates and Sequoia Capital China I, L.P., and/or its affiliates (together with chairman Zhou, the “Consortium Members”), are pleased to submit this preliminary non-binding proposal (the “Proposal”) to acquire all of the outstanding Class A and Class B ordinary shares of the Company that are not already owned by us on the principal terms and conditions described in this letter (the “Transaction”).

We believe that our Proposal provides a very attractive opportunity to the Company’s shareholders. Our Proposal represents a premium of 16.6% to the closing price of the Company’s American depositary shares (“ADSs”, every two ADSs representing three Class A ordinary shares) on June 16, 2015 and a premium of 32.7% to the average closing price of the Company’s ADSs during the last 30 trading days.

Set forth below are the key terms of our Proposal.

1. Consortium. The Consortium Members will form an acquisition vehicle for the purpose of implementing the Transaction. Please also note that the Consortium Members who are shareholders are currently interested only in pursuing the Transaction and are not interested in selling their shares in any other transaction involving the Company.

2. Transaction and Purchase Price. We propose to acquire all of the outstanding Class A and Class B ordinary shares of the Company and ADSs not already owned by us at a purchase price equal to US$51.33 per Class A and Class B ordinary share, or US$77.00 per ADS, as the case may be, in cash through a one-step merger of an acquisition vehicle newly formed by the Consortium Members with and into the Company.

3. Financing. We intend to finance the Transaction with a combination of debt and/or equity capital. Equity financing will be provided by the Consortium Members, in the form of cash and rollover equity in the Company, and from any additional equity investor who may be admitted as a Consortium Member. Debt financing is expected to be provided by loans from third party financial institutions. We are confident that we can timely secure adequate financing to consummate the Transaction.

4. Due Diligence. We believe that we will be in a position to complete customary due diligence for the Transaction in a timely manner and in parallel with discussions on definitive agreements.

5. Definitive Agreements. We have engaged Kirkland & Ellis International LLP as our international legal counsel and are prepared to promptly provide and negotiate definitive agreements for the Transaction.

6. Process. We believe that the Transaction will provide superior value to the Company’s public shareholders. We recognize of course that the board of directors of the Company will evaluate the Transaction independently before it can make its determination whether to endorse it. Given the Chairman’s involvement in the Transaction, we would expect that the independent members of the board of directors will proceed to consider our Proposal and the Transaction.

7. Confidentiality. We are sure you will agree that it is in all of our interests to ensure that we proceed in a strictly confidential manner, unless otherwise required by law, until we have executed definitive agreements or terminated our discussions.

8. No Binding Commitment. This Proposal is not a binding offer, agreement or agreement to make a binding offer or agreement at any point in the future. This letter is a preliminary indication of interest by the Consortium Members and does not contain all matters upon which agreement must be reached in order to consummate the proposed Transaction, nor does it create any binding rights or obligations in favor of any person. The parties will be bound only upon the execution of mutually agreeable definitive documentation.

9. Governing Law. This letter shall be governed by, and construed in accordance with, the internal laws of the State of New York.

* * * * *

In closing, we would like to express our commitment to working together to bring this Transaction to a successful and timely conclusion. Should you have any questions regarding this Proposal, please do not hesitate to contact us. We look forward to hearing from you.

Sincerely,

/s/ Hongyi Zhou

Hongyi Zhou
