(1) Represents ordinary shares issuable pursuant to awards (including the exercise of any options granted) under the 2006 Employee Share Option Scheme (the “2006 ESOP”) and 2011 Share Incentive Plan (the “2011 Plan”) of Qihoo 360 Technology Co. Ltd. (the “Company”). In accordance with Rule 416 of the Securities Act of 1933, as amended (the “Securities Act”), this Registration Statement will also cover any additional ordinary shares which become issuable under the 2006 ESOP, the 2006 ESVS and the 2011 Plan by reason of any stock dividend, stock split, recapitalization or similar transaction.

(2) Pursuant to Rule 457(h)(1), the maximum aggregate offering price is calculated as the sum of (a) the product of 828,850 shares issuable upon the exercise of outstanding options under the 2006 ESOP multiplied by the exercise price of $1.50 per share, which is equal to an aggregate offering price of $1,243,275.00, (b) the product of 70,000 shares issuable upon the exercise of outstanding options under the 2006 ESOP multiplied by the exercise price of $2.20 per share, which is equal to an aggregate offering price of $154,000.00, (c) the product of 4,969,000 shares issuable upon the exercise of outstanding options under the 2006 ESOP multiplied by the exercise price of $2.80 per share, which is equal to an aggregate offering price of $13,913,200.00, (d) the product of 3,752,300 shares issuable upon the exercise of outstanding options under the 2006 ESOP multiplied by the exercise price of $5.20 per share, which is equal to an aggregate offering price of $19,511,960.00, (e) the product of 700,000 shares issuable upon the exercise of outstanding options under the 2006 ESOP multiplied by the exercise price of $5.20 per share, which is equal to an aggregate offering price of $3,640,000.00, (f) the product of 701,500 shares issuable upon the exercise of outstanding options under the 2006 ESOP multiplied by the exercise price of $6.00 per share, which is equal to an aggregate offering price of $4,209,000.00, (g) the product of remaining 5,631,101 shares under the 2011 Plan, multiplied by the exercise price of $27.33 per share, based on the average of the high and low prices for the Company’s American Depositary Shares, or ADSs, as quoted on the New York Stock Exchange on May 18, 2011, which is equal to an aggregate offering price of $153,897,990.33. The total number of ordinary shares issuable pursuant to awards under the 2011 Plan increases on the first day of each year beginning in 2012 and ending in 2021, equal to the greater of (a) five percent of the shares outstanding (on an as converted basis) on the last day of the immediately preceding fiscal year and (b) such greater number of shares of Share as determined by the compensation committee of the board the directors, or another committee or subcommittee of the board of directors.

(3) These ordinary shares may be represented by the Company’s ADSs, every two ADSs representing three Class A ordinary shares. The Company’s ADSs issuable upon deposit of the ordinary shares registered hereby have been registered under a separate registration statement on Form F-6/A (Registration No. 333-172867).

Part I

INFORMATION REQUIRED IN THE SECTION 10(a) PROSPECTUS

Item 1. Plan Information

Not required to be filed with this Registration Statement.

Item 2. Registrant Information and Employee Plan Annual Information

Not required to be filed with this Registration Statement.

Part II

INFORMATION REQUIRED IN THE REGISTRATION STATEMENT

Item 3. Incorporation of Documents by Reference.

The Commission allows the Company to incorporate by reference the information the Company files with it, which means that the Company can disclose important information by referring to those documents. The information incorporated by reference is an important part of this Registration Statement, and information that the Company files later with the Commission will automatically update and supersede this information. The Company incorporates by reference the following documents it has filed, or may file, with the Commission:

(a) The Company’s prospectus filed with the Commission on March 30, 2011 pursuant to Rule 424(b)(4) under the Securities Act (File No. 333-172816) (the “Prospectus”); and

(b) The Company’s Description of Share Capital and Description of American Depositary Shares contained in the Prospectus, and all amendments and reports subsequently filed for the purpose of updating that description.

In addition, this Registration Statement will incorporate by reference all documents the Company files under Section 13(a), 13(c), 14 or 15(d) of the Securities Exchange Act of 1934 (the “Exchange Act”) after the date of this Registration Statement and before the filing of a post-effective amendment stating that all securities offered have been sold or deregistering all securities then remaining unsold. All those documents will be considered a part of this Registration Statement from the respective dates the Company files them. Any statement in a document incorporated or deemed to be incorporated by reference in this Registration Statement will be deemed to be modified or superseded to the extent that a statement contained in this Registration Statement or in any other later filed document that also is or is deemed to be incorporated by reference modifies or supersedes the statement. Any statement modified or superseded will not be deemed, except as modified or superseded, to be a part of this Registration Statement.

Item 4. Description of Securities

Not applicable.

Item 5. Interests of Named Experts and Counsel

Not applicable.

Item 6. 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 that 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 Amended and Restated Articles of Association provide for indemnification of officers and directors for losses, damages, costs and expenses incurred or sustained by them in their capacities as such, except through such person’s actual fraud or willful default.

Pursuant to the form of indemnification agreement filed as Exhibit 10.4 to the Company’s registration statement on Form F-1 (No. 333-172816) declared effective on March 29, 2011 (the “F-1 Registration Statement”), we may agree to indemnify our directors and officers against certain liabilities and expenses arising from their being a director or officer.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers or persons controlling us pursuant to the foregoing provisions, we have been informed that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.

Item 7. Exemption from Registration Claimed

Not applicable.

Item 8. Exhibits

See the attached Exhibit Index.

Item 9. Undertakings

(a) The undersigned registrant hereby undertakes:

(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this Registration Statement:

(i) To include any prospectus required by section 10(a)(3) of the Securities Act;

(ii) To reflect in the prospectus any facts or events arising after the effective date of this Registration Statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in this Registration Statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement.

(iii) To include any material information with respect to the plan of distribution not previously disclosed in this Registration Statement or any material change to such information in this Registration Statement;

provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) shall not apply to information contained in periodic reports filed by the registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference in this Registration Statement.

(2) That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment 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.

(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(4) 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, 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 under the Securities Act;

(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 (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to section 15(d) of the Exchange Act) that is incorporated by reference in this 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 and will be governed by the final adjudication of such issue.
