(b) Restructuring of JV Co 1. The Parties agree that JV Co 1 shall be restructured as follows (each a “JV Co 1 Restructuring Action”):-

(i) within the nine (9) months period following the execution date hereof, the Shareholders shall procure that (A) the LTV Ratio of JV Co 1 be increased to forty percent (40%) or higher, or (B) even though the LTV Ratio of JV Co 1 fails to reach forty percent (40%) or higher, JV Co 1 achieves another financing plan accepted by both Shareholders;

(iii) on the thirtieth (30th) day following the execution date hereof the Shareholders shall procure JV Co 1 (and its Subsidiaries) to distribute, via entrustment loans (unless the Shareholders otherwise agree on any other manner of distribution), all the Available Cash (as defined below) in JV Co 1 (and its Subsidiaries) as of 30 June 2019 (the “First Distribution Cut-off Date”) to the Shareholders (or their respective designated Affiliates) on a pro rata basis based on their then respective Shareholding Percentages in JV Co 1;

(iv) within fifteen (15) Business Days after every 31 December during the term of JV Co 1 (each an “Annual Distribution Cut-off Date”), the Shareholders shall procure JV Co 1 (and its Subsidiaries) to distribute, via entrustment loans (unless the Shareholders otherwise agree on any other manner of distribution), all the Available Cash (as defined below) in JV Co 1 (and its Subsidiaries) as of the relevant Annual Distribution Cut-off Date to the Shareholders (or their respective designated Affiliates) on a pro rata basis based on their then respective Shareholding Percentages in JV Co 1; and

The Shareholders agree that upon either Shareholder’s full exit from its investment in JV Co 1 (including without limitation to WP’s exit upon its exercise of the exit rights pursuant to Section 13 (Exit) of the Investment Agreement), the entrustment loans having been distributed to such exiting Shareholder shall be repaid in full, which repayment shall be completed via set off mechanisms permitted under Applicable Law to minimize actual cash flow.

If item (i) of the JV Co 1 Restructuring Action provided above fails to be completed by the expiry of nine (9) months following the execution date hereof (such expiry date, the “Ad hoc Distribution Cut-off Date”, together with the First Distribution Cut-off Date and the Annual Distribution Cut-off Dates, each a “Distribution Cut-

off Date”), then, at the request of WP, the Shareholders shall procure JV Co 1 (and its Subsidiaries) to immediately distribute (and in no event later than fifteen (15) Business Days after the Ad hoc Distribution Cut-off Date), via entrustment loans (unless the Shareholders otherwise agree on any other manner of distribution), all the Available Cash (as defined below) in JV Co 1 (and its Subsidiaries) as of the Ad hoc Distribution Cut-off Date to the Shareholders (or their respective designated Affiliates) on a pro rata basis based on their then respective shareholding percentages in JV Co 1.

(i) “Available Cash” shall be calculated pursuant to the following formula:-

Available Cash = A — B

Where,

“A” = Cash and Cash Equivalent Investments on the book of JV Co 1 as of the relevant Distribution Cut-off Date + receivables due from Vianet (or its Affiliates) to JV Co 1 (or its Subsidiaries) under the Master Service Agreements (as defined under the Investment Agreement) — payables due from JV Co 1 (or its Subsidiaries) to Vianet (or its Affiliates) under the Sub-contracting Agreements (as defined under the Investment Agreement)); and

(A) within five (5) days after the execution date hereof, the Shareholders shall jointly appoint Ernst & Young (the “Restructuring Auditor”) to determine the Available Cash of JV Co 1 as of each Distribution Cut-off Date; and the Restructuring Auditor may be replaced upon mutual written consent of the Shareholders;

(B) the Restructuring Auditor shall submit a report setting out the amount of Available Cash of JV Co 1 (and its Subsidiaries) as of the First Distribution Cut-off Date and the calculation thereof within fifteen (15) days of its appointment and shall submit a report setting out the amount of Available Cash of JV Co 1 (and its Subsidiaries) as of the Ad hoc Distribution Cut-off Date (if applicable) and each Annual Distribution Cut-off Date and the calculation thereof within fifteen (15) days of the relevant Distribution Cut-off Date; and

(C) the Available Cash as determined by the Restructuring Auditor in the foregoing report shall be final and binding on the Parties in the absence of manifest error.

The Shareholders shall (and shall cause JV Co 1 and its Subsidiaries to) provide the Restructuring Auditor with all information reasonably required for the purposes of determining the Available Cash of JV Co 1 (and its Subsidiaries). The cost of such auditor shall be paid and borne by JV Co 1.

(d) Amendment to the Original Investment Agreement. With effect from the date hereof,

(i) the first paragraph of Section 13 (Exit) of the Original Investment Agreement shall be deleted and replaced in its entirety to read as follows:

“If: (a) neither an IPO nor a REIT of JV Cos and/or its assets occurs by the end of four (4) years (or any other time period mutually agreed to by the Shareholders in writing) after the execution date of the Restructuring Agreement then, at any time after expiry of the foregoing four (4) years (or any other time period mutually agreed to by the Shareholders in writing); (b) any Material Breach under this Agreement or other Transaction Documents or any RA Material Breach occurs; or (c) JV Co 4 fails to undertake any new Project for a period of any consecutive twenty-four (24) months following the JV Co 4 Establishment Date, then the Investor shall be entitled to, in its sole discretion, exit from its investments in the Group Companies via one or more of the following exit mechanisms:-”

(ii) the following definitions shall be added to Exhibit 1.1 (Definitions) of the Original Investment Agreement:

“JV Co 4” shall have the meaning as defined under the Restructuring Agreement.

“JV Co 4 Establishment Date” shall have the meaning as defined under the Restructuring Agreement.

“RA Material Breach” shall have the meaning ascribed to the term “Material Breach” under the Restructuring Agreement.

“Restructuring Agreement” shall mean a restructuring agreement entered into by and among the same Parties hereto on 24 July 2019.”

(iii) the Shareholders agree that they will no longer proceed with the Yizhuang Closing (as defined under the Original Investment Agreement), nor the Tranche Closing (as defined under the Original Investment Agreement) corresponding to the Yizhuang Closing.

(e) WP’s Exit Rights with respect to JV Co 1. In the event WP elects to exit from its investment in JV Co 1 by exercising the Dissolution Exit Option pursuant to Section 13.4(b) (Dissolution Exit) of the Original Investment Agreement, then, within thirty (30) Business Days (the “Exit Put/Call Exercise Period”) after the fair market value of JV Co 1 is determined pursuant to the provisions of Section 13.4(b) (Dissolution Exit) of the Original Investment Agreement (assuming the principal of the entrustment loans extended to the Shareholders pursuant to this Agreement and the interest accrued thereon have been repaid in full),

(i) WP is entitled to, by serving a written notice to Vianet (the “WP Put Notice”), require Vianet to purchase all (but not less than all) the shares then held by WP in JV Co 1 (the “WP Put Shares”) at a price equal to the product of such fair market value multiplied by WP’s then Shareholding Percentage in JV Co 1 (the “WP Put Price”) (the “WP Put Option”), and Vianet shall be obligated to purchase all the WP Put Shares at the WP Put Price, which WP Put Price shall be paid by Vianet to an account designated by WP no later than twenty (20) Business Days after delivery of the WP Put Notice; and

(ii) Vianet is entitled to, by serving a written notice to Vianet (the “Vianet Call Notice”), require WP to sell all (but not less than all) the shares then held by WP in JV Co 1 (the “Vianet Call Shares”) at a price equal to the product of such fair market value multiplied by WP’s then Shareholding Percentage in JV Co 1 (the “Vianet Call Price”) (the “Vianet Call Option”), and WP shall be obligated to sell all the Vianet Call Shares at the Vianet Call Price, which Vianet Call Price shall be paid by Vianet to an account designated by WP no later than twenty (20) Business Days after delivery of the Vianet Call Notice.

If (x) neither WP exercises the foregoing WP Put Option nor Vianet exercises the foregoing Vianet Call Option within the Exit Put/Call Exercise Period or (y) each Shareholder has indicated in writing to the other Shareholder that it will not exercise the WP Put Option or the Vianet Call Option (as applicable) (and if the circumstances described in this item (y) occurs, the Exit Put/Call Exercise Period shall be deemed as early terminated upon such occurrence), WP shall be entitled to trigger the asset distribution pursuant to Section 13.4(c) (Asset Distribution) of the Original Investment Agreement immediately upon the expiry or early termination (whichever is earlier) of the Exit Put/Call Exercise Period. For the avoidance of doubt, WP shall not be allowed to trigger the asset distribution under Section 13.4(c) (Asset Distribution) of the Original Investment Agreement during the Exit Put/Call Exercise Period (or the early terminated Exit Put/Call Exercise Period, as applicable).

(f) Amendment to MSA upon WP’s Exit. The Parties acknowledge and agree that upon WP’s exercise of its exit rights with respect to its investment in JV Co 1 pursuant to Section 13 (Exit) of the Investment Agreement (as amended hereby), WP shall use commercially reasonable efforts to procure the Master Service Agreement between the relevant Project Company and Vianet’s relevant Affiliate be amended to allow such Project to satisfy the requirements of VNET’s finance lease accounting treatment, provided that the amendments will not impose any negative economic impact on the relevant Project Company (including any additional Tax burden), nor impair the marketability or value of the Projects upon WP’s (or its Affiliates’) direct or indirect sale thereof via sale of shares, asset sale or a combination of both (comparing to the situation where there is no amendment to satisfy the finance lease treatment).

(g) Cooperation of the Parties. The Parties agree to cooperate with each other to complete the distribution of the Available Cash of JV Co 1 pursuant to the provisions of Section 2.1(b) (Restructuring of JV Co 1), including without limitation that the Shareholders shall duly authorize the payment of the distributed JV Co 1 Available Cash and do all such thing to give effect to such distribution and payment. In the event any Available Cash of JV Co 1 fails to be distributed to any Shareholder in

such amount and at such time as provided under Section 2.1(b) (Restructuring of JV Co 1) above and such failure is neither due to any Force Majeure Event, nor reasons attributable solely to any Government Entity or the relevant entrusted bank, the overdue sum shall bear an interest at the rate of 0.05% per diem accrued from the applicable due date until the date when all the overdue sum and interest accrued thereon is paid in full to the relevant Shareholder, which interest shall be distributed to the Shareholders together with the Available Cash.

For the avoidance of doubt, Vianet shall (and shall cause its appointed directors to) exercise its rights as a shareholder (or a director, as applicable) of JV Co 4 towards the best interest of JV Co 4.

3.10 Sub-Contracting Agreement. For each future Project that Vianet leases in the entirety of such Project and receives master services from the relevant JV Co 4 Group Company, Vianet shall have a priority right to be sub-contracted with certain services under the JV Co 4 Master Services Agreement under equal terms and conditions, and if Vianet (of its Affiliates) is selected as a sub-contractor pursuant to the preceding sentence, Vianet shall (or shall cause its Affiliates to) enter into a sub-contracting agreement with such JV Co 4 Group Company in such form and substance as mutually agreed upon by the Shareholders (any amendment thereto or termination thereof without the prior consent of WP or its nominated director shall be deemed as a Material Breach by Vianet).

(b) Negative Decision Notice. If (i) the Non-Transferring Shareholder elects not to exercise its right of first offer pursuant to Section 4.3 (Right of First Offer) of Exhibit 3.7 (JV Co 4 Related Provisions); or (ii) the Non-Transferring Shareholder fails to pay the non-refundable deposit pursuant to the provisions of Section 4.3(b) (Completion Period) of Exhibit 3.7 (JV Co 4 Related Provisions), then, (x) the Transferring Shareholder is at liberty to Transfer its Subject Shares to any third party, at a price no less than the price set forth in the Sale Notice, and (y) (only in the event the Investor is the Transferring Shareholder) the Transferring Shareholder shall be entitled to trigger the Trade Sale pursuant to the provisions of Section 3.12 (Trade Sale). Furthermore, in the event Vianet is the Transferring Shareholder, the Investor shall be entitled to exercise its tag-along right pursuant to the provisions of Section 4.4 (Tag Along Right) of Exhibit 3.7 (JV Co 4 Related Provisions).

3.12 Trade Sale. If and only if the Investor is entitled to trigger this Section 3.12 (Trade Sale) pursuant to Section 3.11(b) (Negative Decision Notice) above, the Investor may appoint an investment bank of international repute or a property broker to procure a sale by JV Co 4 of all or substantially all of their assets and undertakings (whether by way of a share sale, an asset

sale or a combination of both) at a valuation acceptable to WP (a “Trade Sale”); provided that each buyer in such Trade Sale shall be a bona fide third party, and the Shareholders shall extend all necessary cooperation and assistance to facilitate the sale (including providing assistance to the potential purchasers and their advisers in the conduct of any due diligence investigation in respect of the JV Co 4 Group Companies). Upon completion of the trade sale, the Shareholders shall take the necessary steps to distribute the sale proceeds from the sale of JV Co 4 to the Shareholders on a pro rata basis pursuant to their respective then-current Shareholding Percentages in JV Co 4. For the avoidance of doubt, any sale or transfer in connection with the Trade Sale shall not be subject to the Transfer restrictions set forth in Section 4 (Transfer Restrictions) of Exhibit 3.7 (JV Co 4 Related Provisions).

3.13 Dissolution Exit.

(a) Dissolution Notice. If the Investor has not fully exited from its investment in JV Co 4 pursuant to Section 3.11 (Exit ROFO) or 3.12 (Trade Sale) above within three (3) months after the Investor issues a Sale Notice pursuant to Section 3.11(a) (Sale Notice), the Investor may (but is not obligated to), in its sole discretion, elect to exit (the “Dissolution Exit Option”) from its investment in JV Co 4 pursuant to Section 3.13(b) (Dissolution Exit) by serving a written notice to Vianet (the “Dissolution Notice”). For the avoidance of doubt, any sale or transfer in connection with the exercise of the Dissolution Exit Option shall not be subject to the Transfer restrictions set forth in Section 4 (Transfer Restrictions) of Exhibit 3.7 (JV Co 4 Related Provisions).

(b) Dissolution Exit. After serving the Dissolution Notice, the Investor may initiate the break-up of JV Co 4 (the “Dissolution Exit”) and arrange for the fair market value of JV Co 4 to be determined as follows:-

(A) Each of the Shareholders shall appoint an Appraiser within five (5) days after the date of service of the Dissolution Notice to each determine the fair market value of JV Co 4, based on the principles set forth in Exhibit 3.13(b) (Appraisal Principles);

(B) The Appraisers shall submit a valuation report setting out the fair market value within one (1) month of their respective appointment; and

(C) The fair market value of JV Co 4 shall be the arithmetic average of the fair market values submitted by the two (2) Appraisers.

The Shareholders shall (and shall cause the JV Co 4 Group Companies to) provide the Appraisers with all information reasonably required for the purposes of determining the fair market value of JV Co 4. The cost of such appraisal shall be paid and borne by JV Co 4.

(c) Asset Distribution. The Shareholders shall take turns to select project companies of JV Co 4 to be transferred to itself or its Affiliates until each of the Shareholders (or their respective Affiliates, as applicable) receives its share in the fair market value of JV Co 4 based on its Shareholding Percentage in JV Co 4; provided, however, that (i) the Investor shall have the right to the first selection, and Vianet shall have the right to the second selection; and (ii) the Investor shall be entitled to a priority to be distributed all available cash of JV Co 4. If, after completion of the foregoing

selection, there is any shortfall between the fair market value of the Project Companies selected by any Shareholder and the amount that should be distributed to such Shareholder pursuant to this Section 3.13(c) (Asset Distribution), such shortfall shall be made up for in cash by the other Shareholder that receives any excess distribution. The Shareholders shall use their respective Best Efforts to cause the transfer or disposal of each project company of JV Co 4 to be completed within 180 days after the date of service of the Dissolution Notice.

3.14 Amendment to JV Co 4 MSA. The Parties acknowledge and agree that upon the Investor’s exercise of its exit rights with respect to its investment JV Co 4 pursuant to this Section 3(III) (JV Co 4 Exit), the Investor shall use commercially reasonable efforts to procure the JV Co 4 Master Service Agreement (if any) between the relevant project company and Vianet’s relevant Affiliate be amended to allow such Project to satisfy the requirements of VNET’s finance lease accounting treatment, provided that (i) the amendments will not impose any negative economic impact on the relevant project company (including any additional Tax burden), nor impair the marketability or value of the Projects upon WP’s (or its Affiliates’) direct or indirect sale thereof via sale of shares, asset sale or a combination of both (comparing to the situation where there is no amendment to satisfy the finance lease treatment); and (ii) Vianet shall, as soon as possible after WP’s exercise of its aforementioned exit right, notify WP in writing setting forth in reasonable detail the amendments necessary to satisfy such finance lease treatment.

3.15 Actions to Effectuate Investor’s Exit. Vianet shall, and shall cause its Affiliates, appointed directors, permitted successors, transferees or assignees to, procure the JV Co 4 Group Companies take any and all necessary actions to effectuate the Investor’s exit pursuant to the provisions of this Section 3(III) (JV Co 4 Exit).

3.16 Late Payment Fee. If either Shareholder fails to pay to the other Shareholder any due and payable amount in a timely manner under this Section 3(III) (JV Co 4 Exit), such default Shareholder shall pay to the other Shareholder a late payment fee at a daily interest rate of 0.05%.

3.17 Taxes. Without prejudicing the rights and interests of the Investor under this Section 3(III) (JV Co 4 Exit), each Shareholder shall pay and bear the Taxes arising from or in connection with the exit mechanism set forth in this Section 3(III) (JV Co 4 Exit) payable by said Shareholder pursuant to the Applicable Law; provided, however, that the Shareholders shall use their respective Best Efforts to ensure that the exit mechanism set forth in this Section 3(III) (JV Co 4 Exit) be implemented in the most tax-efficient way.
