The payments under   the MSAs for the payments due post closing will be reduced by 100%(the   “Discount”), unless a moratorium on VIL’s DOT spectrum payments is granted,   in which case the discount will be 50%, until such time that the aggregate   Discount equals INR 2,400 Cr. Additionally, all undisputed payments   outstanding by Bharti Airtel and VIL to the Enlarged Indus as of the closing   date should be paid on the closing date. VODAFONE AND ABG SECURITY Security   Package: Share Pledge and the Corporate Guarantee as described below.   Description: Subject to the secondary pledge creation below, the Security   Package will come into effect when Vodafone has sold an amount of shares in   Enlarged Indus equal to or greater than the value of the outstanding loan   amount including principal + outstanding interest (the “Loan Amount),   allowing the pledge to Vodafone’s lenders to be released at the point of   completion of such sale (the “Security Effective Date”). The purpose of the   Security Package is to guarantee VIL’s payment obligations (both past and   future) under the MSAs (including Energy). Such payments being made after the   date of creation of corporate guarantee. Corporate Guarantee Amount: The   Corporate Guarantee will be for an amount equal to any cash proceeds realised   from the sale of shares in Enlarged Indus after the Loan Amount has been   repaid, up to a maximum guarantee amount of INR 8,250 Cr (“Maximum Guarantee   Amount”). The Corporate Guarantee Amount shall be reduced by 50% of VIL’s   payments made under the MSAs (including Energy). The Maximum Guarantee Amount   will be reduced by: i) 50% of VIL’s payments (including Energy) made under   the MSAs falling due after the Security Effective Date Payments made under the   Corporate Guarantee Proceeds received pursuant to enforcement of the Share   Pledge (see below), provided that any such sale must be done to unrelated 3rd   parties with a view to maximise proceeds and in any event the amount deducted   from Maximum Guarantee Amount shall be no less than the prevailing market   price of the shares less a 5% discount ii) iii) Share Pledge: After Vodafone   has sold enough shares to repay the Loan Amount and the pledge to Vodafone   lenders has been released, any remaining shares it holds shall be pledged to   Enlarged Indus until the Maximum Guarantee Amount is reduced, as above, to   Zero. Vodafone will be free to sell the pledged shares, free from   encumbrance, in accordance with the shareholders’ agreement, provided the   proceeds of such sale shall result in an equivalent value of Corporate   Guarantee becoming available as described above. If the Loan Amount has not   been repaid within 12 months of D2 closing, Vodafone will create a secondary   pledge on the shares in favour of Enlarged Indus that will become effective   12 months after D2 closing. 11

For such   purposes, the Board of Enlarged Indus will commit to use commercially   reasonable endeavours to assist Vodafone with the sale process (e.g. passing   of appropriate resolutions to assist and support a sale, preparation of a   business plan, marketing materials for the sale process, host management   meetings with potential purchasers and grant the due diligence access   including Q&A). Bharti will provide all such assistance as may be   required in order for Vodafone to run a value maximising sale process. If   Vodafone has been unable to enter into definitive agreements to sell a   sufficient number of shares to repay the Loan Amount and release the pledge   within 18 months of D2 closing and thereafter complete such sale within a   reasonable time, it will grant Bharti a drag along right for such number of   shares whose sale proceeds will enable the repayment of the Loan Amount. Any   such drag can only be done through a sale by Bharti to a non-related 3rd   party on arm’s length terms, and the minimum price paid for Vodafone’s shares   will be at the market price with upto 5% discount. The drag will also be   subject to consent from Vodafone’s lenders.    Default: In the event of default of VIL’s payment obligations under   the MSAs (including Energy), and after the dispute resolution process under   the MSAs has been followed, Enlarged Indus will be able to claim under the   Security Package (including enforcement of pledge and/or claim under the   corporate guarantee) for the default amount subject to the Maximum Guarantee   Amount as at the time of the claim. The Corporate Guarantee will be provided   by Vodafone Group Plc. The Corporate Guarantee can be replaced by a bank   guarantee or cash collateral provided by VIL.
