Indemnified Party or Investor Indemnified Party (as the case may be) whole for any Company Losses or Investor Losses (as the case may be) incurred by it resulting from a breach of a Company Warranty or Investor Warranty (as the case may be). In
connection with the indemnification obligation of the Company Indemnifying Party or the Investor (as the case may be) as set forth above, the Company Indemnifying Party or the Investor (as the case may be) shall, upon presentation of appropriate
invoices containing reasonable detail, reimburse each Company Indemnified Party or Investor Indemnified Party (as the case may be) for all such expenses as they are incurred by such Company Indemnified Party or Investor Indemnified Party (as the

similar facts or circumstances in aggregate exceeds $100,000. 

  

	 	(c)	No Company Indemnifying Party or the Investor shall be liable in respect of a claim for any Investor Losses or Company Losses (as the case may be) unless and until the amount that would be otherwise recoverable from
such Company Indemnifying Party or the Investor (but for this Section 7.3(c)) in respect of such claim, when aggregated with any other amount or amounts recoverable from such Company Indemnifying Party or the Investor in respect of other claims
(excluding any amounts in respect of a claim for which such Company Indemnifying Party or the Investor has no liability because of Section 7.3(b)), exceeds $1,000,000. In such an event, the Company Indemnifying Party or the Investor (as the
case may be) shall be liable for the entire aggregate amount of the Investor Losses or Company Losses (as the case may be) and not just the excess. 

  

  
 14 

	 	(d)	For the avoidance of doubt and notwithstanding any other provision in this Agreement:

	 	(y)	any breach by the Investor of any Fundamental Investor Warranties, combined with any liability under Section 7.3(d)(ii)(y), exceed $448,000,000; and 

 

	 	(ii)	in no circumstance shall the aggregate liability of Company Indemnifying Parties or the Investor (as the case may be) in respect of all Investor Losses or Company Losses (respectively) resulting from or arising out of:

  

	 	(x)	any breach by any Company Indemnifying Party of any Non-Fundamental Company Warranties exceed, in respect of (1) the Company, $89,600,000, and in respect of (2) Sohu Search, $48,000,000 and (3) Photon,
$12,800,000, provided that the aggregate liability of the Company Indemnifying Parties under this Section 7.3(d)(ii)(x) shall not exceed $89,600,000; and 	 

  

	 	(y)	any breach by the Investor of any Non-Fundamental Investor Warranties exceed $89,600,000.

 15 

	 	(f)	For the avoidance of doubt, any claim for a breach of a Company Warranty or Investor Warranty shall be qualified by and subject to any relevant disclosure made in the Disclosure Schedule or otherwise
“Disclosed”, as such term is defined in Schedule 1 to against on such Warranties. 

  

	 	(g)	In determining Investor Losses or Company Losses (as the case may be) subject to indemnification hereunder, the amount of such Investor Losses or Company Losses shall be calculated taking into account and giving credit
against the Investor Losses or the Company Losses, as applicable, any insurance proceeds (or other contribution or payment from any third party) actually received by an Investor Indemnified Party or a Company Indemnified Party, as applicable, (net
of any cost and expenses reasonably incurred in receiving such proceeds, contribution or payment and any increase in premium), and the Investor Indemnified Party or the Company Indemnified Party, as applicable, shall use commercially reasonable
efforts to pursue and collect any such insurance proceeds, contribution or other payments. The foregoing sentence shall not oblige any Investor Indemnified Party or Company Indemnified Party to procure any insurance policy or to take action which
would result in an increase in premiums, a change in coverage or any other adverse change under any insurance policy. 

  

	 	(h)	No Company Indemnified Party or Investor Indemnified Party will be entitled to indemnification with respect to any claim made pursuant to this Section 7 for Company Losses or Investor Losses (as the case may be)
unless written notice of a possible claim for indemnification with respect to such Company Losses or Investor Losses (as the case may be) is given by the Party seeking indemnification to the other Party prior to the expiration of the Survival
Period. 

  

	7.4	Remedies. The indemnity provision set out in this Section 7 shall be the exclusive remedy for any breach of this Agreement or any other Basic Document, or in connection with the matters contemplated hereby
or thereby, except (i) for claims of fraud and (ii) that the Parties shall be entitled to specific performance under this Agreement. The Parties agree that monetary damages may not be adequate compensation for any loss incurred by a Party
by reason of any breach of obligations contained in this Agreement by the other Parties and each Party hereby agrees to waive and not to assert in any action for specific performance of any such obligation the defense that a remedy at law would be
adequate.

shall send written notice (the “Transfer Notice”) to the other Shareholders, which notice shall state, as applicable, (i) the name of the Transferring Shareholder, (ii) the name and address of the proposed transferee (the
“Transferee”), (iii) the number and type of Shares to be Transferred (the “Offered Shares”), (iv) the amount and form of the proposed consideration for the Transfer; (v) the other terms and conditions
of the proposed Transfer; and (vi) the number of Shares the Transferring Shareholder then owns, on an as converted but otherwise non-diluted basis. In the event that the proposed consideration for the Transfer includes consideration other than

consideration per Share for the proposed Transfer is referred to herein as the “Offer Price”. Such Transfer Notice shall be accompanied by true and complete copies of all agreements between the Transferring Shareholder and the
Transferee regarding the proposed Transfer. 

	2.6	Fair Market Value. In the event that any Shareholder objects to the Fair Market Value of any non-cash consideration set forth in a Transfer Notice and the Transferring Shareholder and such other Shareholder
cannot agree on the Fair Market Value within 10 days after the beginning of the Offer, any of such Parties may, by three days written notice to all other Shareholders, initiate appraisal proceedings for determination of the Fair Market Value of such
non-cash consideration. If any Shareholder initiates an appraisal procedure to determine the Fair Market Value, then the Transferring Shareholder and such other Shareholder shall each promptly appoint as an appraiser an individual who is a member of
an internationally recognized investment banking firm. Each appraiser shall, within 30 days of appointment, separately investigate the Fair Market Value of the non-cash consideration as of the proposed Transfer date and shall submit a notice of an
appraisal of such Fair Market Value to each Shareholder. Each appraiser shall be instructed to determine such Fair Market Value without regard to income tax consequences to the Transferring Shareholder as a result of receiving cash rather than other
consideration. If the appraised Fair Market Values (the “Earlier Appraisals”) vary by ten percent (10%) or less of the higher of the Earlier Appraisal, then the average of the two appraised Fair Market Values shall be
controlling as the final Fair Market Value. If the appraised Fair Market Values vary by more than ten percent (10%) of the higher of the Earlier Appraisal, then the appraisers, within 10 days of the submission of the last appraised Fair Market
Value, shall appoint a third appraiser who is a member of an internationally recognized investment banking firm. The third appraiser shall, within 30 days of his appointment, appraise the Fair Market Value of the non-cash consideration (without
regard to the income tax consequences to the Transferring Shareholder as a result of receiving cash rather than other consideration) as of the proposed Transfer date and submit notice of such appraised Fair Market Value to each Shareholder. The Fair
Market Value determined by such third party appraiser shall be controlling as the final Fair Market Value unless such Fair Market Value is greater than both of the two Earlier Appraisals, in which case the higher of the two Earlier Appraisals shall
control, and unless such Fair Market Value is lower than both of the two Earlier Appraisals, in which case the lower of the two Earlier Appraisals shall control. If any Shareholder fails to appoint an appraiser or if one of the two initial
appraisers fails after appointment to submit his appraisal within the required time period, the appraisal submitted by the remaining appraiser shall be controlling. The Transferring Shareholder and the other Shareholder shall each bear the cost of
its respective appointed appraiser, and the cost of the third appraiser shall be shared one-half by the Transferring Shareholder and one-half by the objecting Shareholder. If a Shareholder delivers an Acceptance Notice prior to the final
determination of the Fair Market Value pursuant to such appraisal proceedings, such Shareholder may give written notice to the Transferring Shareholder revoking such Acceptance Notice within 10 days after the determination of the appraised Fair
Market Value, if such Shareholder chooses not to purchase or sell the Offered Shares. 

	2.7	Right of First Refusal. 

  

	 	(a)	First Refusal Right. If any of Sohu Search, Photon, any Member of Sogou Management or any of their Affiliates or Permitted Transferees is the Transferring Shareholder, Tencent shall have the right to purchase in
aggregate all or part of the Offered Shares at a purchase price in cash equal to the Offer Price per Share and upon the other terms and conditions set forth in the Transfer Notice (the “First Refusal Right”). If Tencent or any of
its Affiliates or Permitted Transferees is the Transferring Shareholder, Sohu Search and Photon shall have the First Refusal Right. The Shareholder that has the First Refusal Right (Tencent or Sohu Search and Photon, as applicable) shall be referred
to as the “Offeree(s)”. Each Offeree shall have the right to assign to an Affiliate of such Offeree its right to acquire Offered Shares pursuant to this Section 2.7(a). In the event that an Offeree cannot exercise its First Refusal
Right because the exercise of such right may not obtain the necessary Regulatory Approvals, such Offeree shall have the right to assign its First Refusal Right to a third party to be approved by the Transferring Shareholder, such approval not to be
unreasonably withheld or delayed. 

  

	 	(b)	Exercise of Rights. The First Refusal Right of the Offeree(s) under Section 2.7(a) shall be exercisable by delivering written notice of exercise (an “Acceptance Notice”) within 30 days after
delivery of the Transfer Notice (the “Offer Period”) to the Transferring Shareholder specifying the number of Offered Shares that each Offeree wishes to purchase. Subject to Section 2.6, an Acceptance Notice shall be
irrevocable and shall constitute a binding agreement by such Offeree to purchase the stated number of the Offered Shares. The failure of an Offeree to give an Acceptance Notice within the Offer Period shall be deemed to be a waiver of such
Offeree’s First Refusal Right. If Sohu Search and Photon are the Offerees, Sohu Search and Photon shall each have a Pro Rata right to purchase the Offered Shares. 

 

	 	(c)	Sale to Third Party Purchaser. Subject to Section 2.9, if the Offeree(s) does not elect to purchase all of the Offered Shares, the Transferring Shareholder may Transfer, subject to Section 2.8, all or any
remaining Offered Shares to the Transferee identified in the Transfer Notice on the terms and conditions set forth in the Transfer Notice; provided, however, that (i) such sale is bona fide, (ii) the price for the sale to the Transferee is
a price not less than the Offer Price per Share and the sale is otherwise on terms and conditions no less favorable to the Transferring Shareholder than those set forth in the Transfer Notice, and (iii) the Transfer is completed within three
months after the giving of the Transfer Notice. If such a Transfer does not occur within such three-month period for any reason, the restrictions provided for herein shall again become effective, and no Transfer of Shares may be made by the
Transferring Shareholder thereafter without again complying with this Section 2. 

	 	(d)	Closing. The closing of any purchase of Offered Shares by the Offeree(s) shall be held at the principal office of the Company at 11:00 a.m. local time on the 45th day after the giving of the Transfer Notice, or
on the 15th day after final determination of the non-cash consideration pursuant to Section 2.6 (if applicable) or at such other time and place as the parties to the transaction may agree. The
said 45 day period or such other period as specified in the preceding sentence shall be extended for an additional period of up to 45 days if necessary to obtain any Regulatory Approvals required for such purchase and payment. At such closing, the
Transferring Shareholder shall deliver certificates representing the Offered Shares that the Offeree(s) elected to purchase, accompanied by duly executed instruments of transfer and the Transferring Shareholder’s portion of the requisite
transfer taxes, if any. Such Offered Shares shall be free and clear of any Encumbrance (other than Encumbrances arising hereunder or attributable to actions by the Offeree(s)), and the Transferring Shareholder shall so represent and warrant and
shall further represent and warrant that it is the beneficial and record owner of such Offered Shares. The Offeree(s) purchasing Offered Shares shall deliver at such closing (or on such later date or dates as may be provided in the Transfer Notice
with respect to payment of consideration by the proposed Transferee) payment in full of the Offer Price per Share. At such closing, all of the parties to the transaction shall execute such additional documents as may be necessary or appropriate to
effect the sale of the Offered Shares to the Offeree(s). Any stamp duty or transfer taxes or fees payable on the transfer of any Offered Shares shall be borne and paid equally by the Transferring Shareholder and the Offeree(s). The Parties
acknowledge that Sohu Search and Libra Management have entered into a voting agreement on the date hereof with respect to the voting of Libra Management’s Equity Securities in the Company (the “Voting Agreement”). The Voting
Agreement provides that if any Member of Libra Management Transfers Equity Securities in the Company to any other Person, such transferee shall be bound by the provisions of the Voting Agreement. Sohu Search hereby irrevocably agrees that, in the
event any Member of Libra Management Transfers Equity Securities in the Company to Tencent or its Affiliate, neither Tencent nor its Affiliates shall be required to become a party to or be otherwise subject to the terms of the Voting Agreement.

  

	2.8	Tag-Along Rights. 

  

	 	(a)	Tag-Along Rights. If a Transferring Shareholder proposes to make a Transfer, provided that an Offeree has not exercised its First Refusal Right, the Offeree shall have the right (the “Tag-Along
Right”) but not the obligation to require the Transferee in a Transfer to purchase from the Offeree, for the same consideration per Share and upon the same terms and conditions as to be paid and given to the Transferring Shareholder, up to
a maximum of the number of Offered Shares multiplied by a fraction, the numerator of which is the number of Shares held by the Offeree and the denominator of which is the total number of Shares held by the Transferring Shareholder and all Offerees,
in each case on an as converted but otherwise non-diluted basis. If an Offeree elects to exercise its Tag-Along Right, the number of Shares to be Transferred by the Transferring Shareholder shall be reduced accordingly. 

	 	(b)	Tag-Along Notice. If an Offeree elects to exercise its Tag-Along Right (the “Tag-Along Shareholder”), the Offeree shall deliver a written notice of such election to the Transferring Shareholder
within the Offer Period, specifying the number of Shares with respect to which it has elected to exercise its Tag-Along Right. Subject to Section 2.6, such notice shall be irrevocable and shall constitute a binding agreement by such Shareholder to
Transfer such Shares on the terms and conditions set forth in the Transfer Notice. The failure of the Tag-Along Shareholder to give an Acceptance Notice within the Offer Period shall be deemed to be a waiver of such Tag-Along Shareholder’s Tag
Along Right. 

  

	 	(c)	Consummation. The closing of the sale of Shares pursuant to the Tag-Along Right shall occur simultaneously with the Transfer of Shares by the Transferring Shareholder. Where any Shareholder has properly elected
to exercise its Tag-Along Right and the proposed Transferee fails to purchase Shares from such Shareholder, the Transferring Shareholder shall not make the proposed Transfer, and if purported to be made, such Transfer shall be void.

  

	2.9	Termination of Business Cooperation Agreements. In the event that: 

  

	 	(a)	any Equity Securities are Transferred to Qihoo 360 Technology Co. Ltd., Alibaba Group Holding Limited or their respective Affiliates, or 

 

	 	(b)	there is a Change of Control of Sohu.com Inc. and the Person or Persons that acquires Control of Sohu.com Inc. is Qihoo 360 Technology Co. Ltd., Alibaba Group Holding Limited and/or their respective Affiliates,

 Tencent shall have the right upon notice in writing to the Company to terminate the Business Resource Sharing Agreement, the
Mobile Browser Cooperation Agreement and the Video Cooperation Agreement, each made between an Affiliate of Tencent, an Affiliate of the Company and other parties named therein entered into on the date hereof, as amended from time to time. 

 

	2.10	Avoidance of Restrictions. The Parties agree that the Transfer restrictions in this Agreement and in the Charter Documents shall not be capable of being avoided by the holding of Shares indirectly through a
company or other entity that can itself be sold in order to dispose of an interest in Shares free of such restrictions. Any Transfer or other disposal of any shares (or other interest) resulting in any Change of Control of a Shareholder or of any
company (or other entity) having Control over that Shareholder shall be treated as being a Transfer of the Shares held by that Shareholder, and the provisions of this Agreement and the Charter Documents that apply in respect of the Transfer of
Shares shall thereupon apply in respect of the Shares so held. 

	2.11	Transfer of Convertible Securities. Any Transfer of Equity Securities exercisable or convertible into or exchangeable for Shares will be deemed for the purposes of this Section 2 to be a Transfer of Shares.

  

	2.12	Notice of Transfer. Within five Business Days after registering any Transfer of Shares or other Equity Securities on its books, the Company shall send a notice to each Shareholder stating that such Transfer has
taken place and setting forth the name of the Transferring Shareholder, the name of the Transferee and the number and class of Equity Securities involved. 

SECTION 3 

PREEMPTIVE RIGHTS AND VESTING OF OPTIONS 
  

	3.1	Restrictions. The Company shall not issue any securities (including, without limitation, any Equity Securities or any debt or other securities of any kind) of any type or class to any person (the

such Shareholder’s Pro Rata Share of such issuance for a per unit consideration, payable solely in cash, equal to the per unit consideration to be paid by the Proposed Recipient and otherwise on the same terms and conditions as are offered to
the Proposed Recipient; provided that the foregoing restriction shall not apply to (i) the issuance or sale of up to 36,000,000 Ordinary A Shares (or options therefor) (as adjusted for any share splits, share dividends and the like) to

specifying the number of securities to be purchased by such Shareholder and the calculation by such Shareholder of its Pro Rata Share. Except as provided in the next succeeding sentence, failure by any Shareholder to give such notice within such 15
day period shall be deemed a waiver by such Shareholder of its rights under this Section 3 with respect to such Proposed Issuance. If any Shareholder fails to give the notice required under this Section 3.3 solely because of the Company’s
failure to comply with the notice provisions of Section 3.2, then the Company shall not issue securities pursuant to this Section 3 and if purported to be issued, such issuance of securities shall be void. 

 

	3.4	Vesting of Options. Each Member of Sogou Management agrees that this Agreement shall apply to all Equity Securities that such Person holds, whether directly or indirectly, in the Company on the date hereof or

“Sogou Inc. (the “Company”) is an exempted company incorporated under the laws of the Cayman Islands, and the shares
represented by this certificate shall not be sold, assigned, transferred, exchanged, mortgaged, pledged or otherwise disposed of or encumbered without compliance with the provisions of that certain Shareholders’ Agreement among the Company and
the shareholders of the Company named therein or subsequently adhering thereto. A copy of such Shareholders’ Agreement is on file at the principal offices of the Company. The Company will not register the transfer of such shares on its register
of members unless and until the transfer has been made in compliance with the terms of such Shareholders’ Agreement.” 

	12.2	Discrepancies. If there is any discrepancy between any provision of this Agreement and any provision of the Charter Documents or the charter documents of any Subsidiary, the provisions of this Agreement shall

	12.3	Assignment. This Agreement shall inure to the benefit of, and be binding upon, the successors and Persons to whom a Shareholder transfers Equity Securities in the Company in a Transfer permitted under this

	12.4	No Agency. No Shareholder, acting solely in its capacity as a Shareholder, shall act as an agent of the Company or have any authority to act for or to bind the Company, except as authorized by the Board. For the
purposes of this Section, unless acting expressly solely in its capacity as a Shareholder, any Shareholder who is a director or officer or employee of any Group Company acting in the ordinary course of business of any Group Company shall be

shall indemnify the Company and each other Shareholder against, any losses, claims, damages, liabilities, judgments, fines, obligations, expenses and liabilities of any kind or nature whatsoever (including any investigative, legal and other expenses

reason of such violation.

to another, or partners as to any third party, or create any fiduciary relationship among themselves, by virtue of their status as Shareholders. To the extent that any Shareholder, by word or action, represents to another Person that any Shareholder
is a partner or that the Company is a partnership, the Shareholder making such representation shall be liable to any other Shareholders that incur any losses, claims, damages, liabilities, judgments, fines, obligations, expenses and liabilities of
any kind or nature whatsoever (including any investigative, legal or other expenses reasonably incurred in connection with, and any amount paid in settlement of, any pending or threatened legal action or proceeding) arising out of or relating to
such representation. 

	12.6	Amendment. This Agreement may be amended, modified or supplemented with the written instrument executed by Sogou, Sohu Search and Tencent, and any such amendment shall be valid and binding on all Parties.

  

	12.7	Waiver. No waiver of any provision of this Agreement shall be effective unless set forth in a written instrument signed by the Party waiving such provision. No failure or delay by a Party in exercising any right,
power or remedy under this Agreement shall operate as a waiver thereof, nor shall any single or partial exercise of the same preclude any further exercise thereof or the exercise of any other right, power or remedy. Without limiting the foregoing,
no waiver by a Party of any breach by any other Party of any provision hereof shall be deemed to be a waiver of any subsequent breach of that or any other provision hereof. 

 

	12.8	Entire Agreement. This Agreement represents the entire understanding and constitutes the whole agreement among the Parties relating to the subject matter hereof and supersedes any prior agreements or
understandings relating to such subject matter. 

  

	12.9	Severability. Each and every obligation under this Agreement shall be treated as a separate obligation and shall be severally enforceable as such and in the event of any obligation or obligations being or
becoming unenforceable in whole or in part. To the extent that any provision or provisions of this Agreement are unenforceable they shall be deemed to be deleted from this Agreement, and any such deletion shall not affect the enforceability of this
Agreement as remain not so deleted.

counterpart and shall have effect from the date first above written. 

  

	12.1	Consent to Specific Performance. The Parties declare that it may be impossible to measure in money the damages that would be suffered by a Party by reason of the failure by the other Parties to perform any of the
obligations hereunder. Therefore, if any Party shall institute any action or proceeding to enforce the provisions hereof, the Party against whom such action or proceeding is brought hereby waives any claim or defense therein that the other Parties
has an adequate remedy at law.
