In the event the amount available under applicable Law with NPIP to redeem the OCRPSs or in case of Converted Shares, to buy back the Converted Shares is less than the Liquidity Amount as a result of accumulated losses in NPIP or due to insufficient profits or funds for any other reason, Napo Group undertakes to immediately make available the necessary funds to NPIP to the extent of such differential amount in order to enable NPIP to redeem the applicable OCRPSs or in case of Converted Shares to buy back the Converted Shares for an amount equivalent to the Liquidity Amount.

If the Investor is holding NPIP Equity, then in the event of winding-up, dissolution and/or liquidation of Napo (except by virtue of a Corporate Reorganization as addressed in Clause 7(e) below), to the extent that proceeds of such winding-up, dissolution and/or liquidation are legally available for and distributed to Napo Common Stock holders, NPIP shall be entitled to its Pro Rata Share of such proceeds against NPIP Napo Common Stock and NPIP shall within fifteen (15) days of the receipt of the Liquidity Amount utilize the same to redeem the OCRPS or buy back the Converted Shares.

(ii) If the Investor is holding NPIP Equity, then in the event of winding-up, dissolution and/or liquidation of NPIP, NPIP shall be permitted to sell the NPIP Napo Common Stock with the prior consent of the Investor, and the Investor shall be entitled to such an amount equal to the amount to which the Investor would be entitled as a creditor of NPIP up to the Liquidity Amount (net of any charges related to the receipt of such cash proceeds, including but not limited to taxes of any kind and taxes that may be owed by NPIP to any Governmental Authority as a result of such receipt). In the event the amount available under applicable Law with NPIP to redeem the OCRPSs or in case of Converted Shares, to buy back the Converted Shares is less than the Liquidity Amount as a result of accumulated losses in NPIP or due to insufficient profits or funds for any other reason, Napo Group undertakes to immediately make available the necessary funds to NPIP to the extent of such differential amount in order to enable NPIP to redeem the applicable OCRPSs or in case of Converted Shares to buy back the Converted Shares for an amount equivalent to the Liquidity Amount. Notwithstanding the foregoing, such obligation of Napo Group will not apply in any situation in which due to a change in

applicable Law from the Effective Date or force majeure the Napo Group are prohibited from delivering the Liquidity Amount in full to the Investor in connection with redeeming the OCRPSs or in case of Converted Shares to buy back the Converted Shares. Until such redemption or buy back, Napo Group undertakes and is obligated to not to use the Liquidity Amount for any other purpose. Upon termination of such force majeure or a further change in applicable Law which no longer prohibits the Napo Group from delivering the Liquidity Amount in full to the Investor, the Napo Group shall redeem the OCRPSs or buy back the Converted Shares, as the case may be, and deliver the Liquidity Amount (or such portion as has not yet been delivered) to Investor.

e) Pre-emptive Rights. In the event that, after the Effective Date, and so long as the Investor holds any NPIP Equity, NPIP proposes to issue any New Securities (other than Exempted New Securities), the Investor shall have a preemptive right, to subscribe for a Pro Rata Share of such New Securities. Not less than fifteen (15) Business Days before a proposed issuance of New Securities (a “Proposed Issuance”), NPIP shall deliver to the Investor a written notice of the Proposed Issuance setting forth (i) the number, type and terms of the Securities to be issued, (ii) the consideration to be received by NPIP in connection with the Proposed Issuance and (iii) the identity of the allottees. Within ten (10) Business Days following delivery of the notice referred to in this Clause 5(e), the Investor, if it elects to exercise its rights under this Clause 5(e) shall give written notice to NPIP specifying the number of Securities to be purchased by the Investor (which shall not be greater than its Pro Rata Share of such New Securities) and NPIP shall issue and allot such number of New Securities to the Investor within five (5) Business Days thereafter, upon receipt of the consideration specified in the aforesaid notice. Provided further that NPIP shall not issue any New Securities after the date of execution of this Agreement, as mentioned above, till the Completion Date, as defined in Subscription Agreement.

In the event that, after the Effective Date and until the Termination Date, and only so long as the Investor holds any NPIP Equity or NPIP Napo Common Stock as per Clause 7(a), Napo proposes to issue any New Securities (other than Exempted New Securities), the Investor shall have a preemptive right to subscribe for a Pro Rata Share of such New Securities on the terms and conditions offered by Napo (the “Pre-emptive Rights”). Napo undertakes to issue to the Investor such New Securities as per its Pro Rata Shares of such New Securities if applicable Law allows the Investor to hold such New Securitis or to allow the Investor to subscribe to such New Securities by any of its Affiliates in accordance with the terms and conditions offered by Napo. Prior to such issuance, Napo shall deliver a notice of the proposed issuance of New Securities to the Investor (a “Proposed Issuance”), Napo shall deliver to the Investor a written notice of the Proposed Issuance setting forth (i) the number, type and terms of the New Securities to be issued and (ii) the consideration to be received by Napo in connection with the Proposed Issuance (the “Preemptive Notice”). Within ten (10) Business Days following delivery of the Preemptive Notice, the Investor, if it elects to exercise its rights under this Clause 5(e), shall give written notice to Napo specifying the number of New Securities to be purchased by the Investor or its Affiliates (which shall not be greater than its Pro Rata Share of such New Securities). Napo shall issue and allot such number of New Securities as communicated by Investor to Napo within five (5) Business Days after receipt of the

consideration specified in the Preemptive Notice and Investor’s compliance with all other terms and conditions specified in the Preemptive Notice. If the Investor fails to agree in writing within such ten (10) Business Day period to purchase Investor’s Pro Rata Share even after complying with all other terms in the Preemptive Notice within such ten (10) Business Days, it shall forfeit the right hereunder to purchase its Pro Rata Share of such New Securities. “Termination Date” shall be the earlier of such time that Napo has (x) become a “reporting issuer” filing periodic reports (10-Qs/10-Ks/8-Ks) with the United States Securities and Exchange Commission pursuant to the Securities Exchange Act of 1934, as amended, or (y) a merger or consolidation of Napo with or into another entity (other than a merger or consolidation with a wholly-owned subsidiary or a reincorporation of the Company in a different jurisdiction) or any Corporate Reorganization. Napo shall have one hundred and twenty (120) Business Days following delivery of the Preemptive Notice to Investor to issue the New Securities not purchased by Investor. Thereafter, Napo shall again comply with the Preemptive Rights provisions set forth in this paragraph until the Termination Date. Notwithstanding the foregoing, if Investor is entitled to exercise Pre-emptive Rights under this paragraph and wishes to exercise the same by way of structure as availed under this Agreement because it is not eligible under applicable Law to acquire such New Securities directly, Napo undertakes to issue to the Investor such New Securities as per its Pro Rata Share of such New Securities by way of the structure as availed in this Agreement only if the Investor’s investment amount of its Pro Rata Share of such New Securities is at least equal to $500,000 and then Investor exercises its Pre-emptive Rights to invest no less than $500,000 in the issuance of such New Securities.

f) Anti-Dilution Rights. In the event that if, after the Effective Date but prior to redemption or exchange of the OCRPSs or buy back or exchange of the Converted Shares as the case may be in accordance with the terms of this Agreement, NPIP issues New Securities (other than Exempted New Securities) to any Person(s) other than to the Investor (“Follow on Investment Valuation”), in the event the Investor is holding OCRPS the number of Shares that the OCRPSs shall be converted into in the event that the Investor exercises its rights under Clause 7(f) below shall be adjusted, to reflect the price at which the New Securities are being offered, such that the number of Shares that the OCRPSs held by the Investor convert into (pursuant to Clause 7(f) below) is as per its Investor Share Entitlement and in the event the Investor is holding the Converted Shares, NPIP shall issue such additional Shares to the Investor to reflect the price at which the New Securities are being offered, such that the Investor holds such number of Shares, as provides the Investor with an IRR of 30% at the Follow on Investment Valuation.

g) Dividends etc. In the event that post the Effective Date and prior to redemption or exchange of the OCRPSs or buy back or exchange of the Converted Shares in accordance with the terms of this Agreement, Napo declares and pays a dividend, bonus or other entitlement on the NPIP Napo Common Stock, the Investor will be entitled to any such dividend, bonus and other entitlements on the NPIP Napo Common Stock, in proportion to its Investor Share Entitlement (net of any charges related to such dividends, bonuses and other entitlements that would ordinarily apply to such payments including but not to taxes of any kind and taxes that may be owed by NPIP to any Governmental Authority as a result of the receipt of such payment) in accordance with the terms of this Agreement.

In the event the amount available under applicable Law with NPIP to redeem the OCRPSs or to buy back the Converted Shares held by the Investor is less than the Liquidity Amount as a result of accumulated losses in NPIP or due to insufficient profits or funds for any other reason, Napo Group undertakes to immediately make available the necessary funds to NPIP to the extent of such differential amount in order to enable NPIP to redeem the applicable OCRPS’s or to buy back the Converted Shares held by the Investor for an amount equivalent to the Liquidity Amount. Notwithstanding the foregoing, such obligation of Napo Group will not apply in any situation in which due to a change in applicable Law from the Effective Date or force majeure, the Napo Group are prohibited from delivering the Liquidity Amount in full to the Investor in connection with redeeming the OCRPSs or to buy back the Converted Shares held by the Investor. However, until such redemption or buy back, Napo Group undertakes and is obligated to not to utilize the Liquidity Amount for any other purpose. Upon termination of such force majeure or a further change in applicable Law which no longer prohibits the Napo Group from delivering the Liquidity Amount in full to the Investor, the Napo Group shall redeem the OCRPSs or buy back the Converted Shares, as the case may be, and deliver the Liquidity Amount (or

such portion as has not yet been delivered) to Investor. Subject to the foregoing, within fifteen (15) Business Days from the receipt of the Liquidity Amount, NPIP shall utilize the Liquidity Amount, subject to the provisions of the Companies ▇▇▇, ▇▇▇▇, and applicable Law, to redeem such number of OCRPSs or to buy back such number of Converted Shares held by the Investor in the ratio of the Investor Share Entitlement with respect to the number of shares of NPIP Napo Common Stock sold (adjusted appropriately for stock splits, combinations, reclassifications and the like). Simultaneously, with the receipt of the Liquidity Amount, the Investor shall sell and Napo shall purchase or nominate a Person to purchase such number of the Initial Shares, pro rated with respect to the number of shares of NPIP Napo Common Stock sold (such Initial Shares shall be transferred for a consideration being the par value of such shares). This pro rated sale of the Initial Shares shall apply to each successive sale of NPIP Napo Common Stock, such that when all the NPIP Napo Common Stock (but in no event required to be in excess of Investor’s Share Entitlement) is finally sold, then the Investor shall have no further NPIP Equity or any other rights in NPIP, or under this Agreement.

d) If the Investor has not fully exercised its rights pursuant to Clause 7(c) above, then immediately upon expiry of the Tenure, NPIP shall, with the prior consent of the Investor, have the right to sell the outstanding NPIP Napo Common Stock held by NPIP and use the proceeds obtained therefrom to compulsorily redeem the outstanding OCRPS and credit to the Investor’s account an amount equivalent to the Liquidity Amount applicable to such outstanding OCRPS within fifteen (15) days of the date of expiry of the Tenure. In the event the amount available under applicable Law with NPIP to redeem the OCRPSs is less than the Liquidity Amount applicable to such outstanding OCRPSs as a result of accumulated losses in NPIP or due to insufficient profits or funds for any other reason, Napo Group undertakes to immediately make available the necessary funds to NPIP to the extent of such differential amount in order to enable NPIP to redeem the applicable OCRPS’s for an amount equivalent to the Liquidity Amount. Simultaneously, with the receipt of the Liquidity Amount, the Investor shall sell and Napo shall purchase or nominate a Person to purchase the outstanding Initial Shares (such Initial Shares shall be transferred for a consideration being the par value of such shares), such that when all the NPIP Napo Common Stock is finally sold, then the Investor shall have no further NPIP Equity or any other rights in NPIP, or under this Agreement.

e) Notwithstanding the foregoing, in the event of a Corporate Reorganization where the Investor has not fully exercised its rights pursuant to Clause 7(c) above, then upon consummation of the Corporate Reorganization, NPIP shall redeem the OCRPS then outstanding and credited to the Investor’s account(s) in consideration of the Corporate Reorganization Consideration attributable to the NPIP Napo Common Stock and thereafter allocated to the Investor based on the Investor’s Share Entitlement, and in case the Investor is holding Converted Shares pursuant to Clause 7(f) below, NPIP shall buy back the Converted Shares held by the Investor and credited to the Investor’s account(s) in consideration of the Corporate Reorganization Consideration attributable to the NPIP Napo Common Stock and thereafter allocated to the Investor based on the Investor’s Share Entitlement, which consideration if in cash shall be credited to a bank account as designated by the Investor and otherwise appropriately transferred to the Investor; provided, however, that if the Corporate Reorganization Consideration is equity and the

Investor is not eligible under applicable Law to receive equity securities as the Corporate Reorganization Consideration, at the option of the Investor, either (X) NPIP shall establish a structure reasonably acceptable to the Investor that would permit the Investor to retain the beneficial interest in such Corporate Reorganization securities pari passu with the Investor’s beneficial interest through the OCRPSs or Converted Shares in the NPIP Napo Common Stock or (Y) if the third-party acquiror is a privately held corporation, the Investor may elect to receive cash in lieu of establishing such a structure, and Napo shall in good faith but with no legal or contractual obligation attempt to pay and NPIP shall pay the Investor the fair market value of such securities in cash as such equity securities are valued in the Corporate Reorganization (net of any charges related to the receipt of such consideration, including but not limited to commissions and taxes of any kind and taxes that may be owed by NPIP to any Governmental Authority in respect of such consideration). In the event the amount available under applicable Law with NPIP to redeem the OCRPSs or buy back the Converted Shares held by the Investor is less than the Corporate Reorganization Consideration attributable to the NPIP Napo Common Stock and thereafter allocated to the Investor based on Investor’s Share Entitlement applicable to such outstanding OCRPSs or Converted Shares as a result of accumulated losses in NPIP or due to insufficient profits or funds for any other reason, Napo Group undertakes to immediately make available the necessary funds to NPIP to the extent of such differential amount in order to enable NPIP to redeem the applicable OCRPS’s or buy back the Converted Shares for an amount equivalent to the Corporate Reorganization Consideration attributable to the NPIP Napo Common Stock and thereafter allocated to the Investor based on Investor’s Share Entitlement. Simultaneously, with the aforesaid, the Investor shall sell and Napo shall purchase or nominate a Person to purchase the outstanding Initial Shares (such Initial Shares shall be transferred for a consideration being the par value of such shares), such that when all the NP IP Napo Common Stock (but in no event required to be in excess of Investor’s Share Entitlement) is finally sold, then the Investor shall have no further NPIP Equity or any other rights in NPIP, or under this Agreement.

f) At any time during the Tenure, the Investor shall be entitled to convert the OCRPSs then outstanding and NPIP shall issue to the Investor such number of Shares being equivalent to the Investor Share Entitlement (“Converted Shares”); provided, however, that the Investor shall exercise the conversion option attached to all the OCRPSs held by it in a single instance and such conversion is subject to and in compliance with all applicable Laws.

Napo Group hereby undertakes that in the event the Investor has exercised its option under this Clause 7(f), in all the scenarios of distribution of Liquidity Amount Napo shall not offer its Shares to NPIP in the process of buy back of Converted Shares by NPIP.

g) Notwithstanding anything to the contrary mentioned in this Agreement, in the event the Investor ceases to hold all the OCRPSs (and consequently any Shares including Converted Shares) whether by exchange, or redemption, or buy back and has received all amounts owed to it pursuant to this Agreement, the Investor will cease to have any rights or interest in relation to the OCRPSs or Converted Shares, or any rights or interest in the

NPIP Napo Common Stock, Napo, or NPIP and this Agreement shall terminate with respect to the Investor in accordance with Clause 17 hereto.

14) INDEMNITY

a) Napo undertakes to indemnify and keep indemnified for a period of two (2) years from the date of this Agreement (the “Indemnified Period”) the Investor and its directors (the “Investor Parties”) against any loss, liability, claims, costs and expenses directly suffered by the Investor Parties as a result of, or in connection with or arising from a breach by Napo of the NPIP warranties and/or Napo Warranties and/or any terms of the

Transaction Agreements not to exceed $500,000 in the aggregate (collectively, the “Losses”). Such indemnity shall extend to include all costs, charges and expenses which Investor may pay or incur in disputing or defending any claim or action or other proceedings where authorized in accordance with the provisions of this Clause in respect of which indemnity may be sought under this Clause.

b) Notwithstanding the foregoing, without in any way limiting the obligation of Napo to indemnify the Investor Parties pursuant to the above Clause, Napo shall not be required to indemnify the Investor Parties for breach of any NPIP Warranties and/or Napo Warranties and/or any terms of the Transaction Agreements (A) unless written notice thereof has been given by the Investor Parties during the Indemnified Period and (B) unless and until the aggregate dollar amount of all Losses resulting or arising from any and all such breaches exceeds an aggregate of $50,000, at which point Napo shall indemnify the Investor Parties for the aggregate amount of all such Losses incurred, not to exceed $500,000 in the aggregate for all such Losses.

c) The foregoing indemnities of Napo shall not apply with respect to any breach by Napo of NPIP Warranties and/or Napo Warranties and/or any terms of the Transaction Agreements that results in a claim by a third party, unless the Investor Parties shall, with reasonable promptness, provide Napo with copies of any claims or other documents received and shall otherwise make available to Napo all relevant information material to the defense of any claim against the Investor Parties which shall serve as the basis for a claim by the Investor Parties pursuant to the terms hereof. Notwithstanding the foregoing, the Investor Parties’ failure to give prompt notice or to provide copies of documents or to furnish relevant information shall not constitute a defense (in part or in whole) to any claim by the Investor Parties against Napo, except and only to the extent that such failure by the Investor Parties shall result in material prejudice to Napo. Napo shall have thirty (30) days (or such shorter period as may be necessitated by the exigencies of such claim) within which to elect to defend such claim at its own expense and with counsel of its own choosing (who shall be reasonably acceptable to the Investor Parties), provided that the Investor Parties shall have the right at all times to fully participate in the defense thereof at their own expense. Napo may not settle or compromise any such claim without the prior written consent of the Investor Parties, which consent shall not unreasonably be withheld unless as part of the settlement Napo obtains an unconditional release of the Investor Parties. If Napo shall, within such thirty (30) days (or shorter) period, fail to defend such claim with counsel reasonably acceptable to the Investor Parties, the Investor Parties shall have the right, but not the obligation, to undertake the defense of such claim. The Investor Parties may not settle or compromise any such claim without the prior written consent of Napo, which consent shall not be unreasonably withheld unless as part of the settlement the Investor Parties obtain an unconditional release of Napo.

d) Any claim of indemnity made by the Investor Parties under this Clause must be made in good faith in a writing executed by an officer of the Investor (the “Notice of Claim”) delivered to Napo within the Indemnified Period, and, if raised by such date, such claim shall survive until final resolution thereof. Any such Notice of Claim will set forth with reasonable specificity the nature of the claim for indemnity and, if then determinable, the

approximate amount of the claimed Losses, and shall include copies of any formal demand or complaint.

e) For the avoidance of doubt, Napo shall be liable in accordance with the terms of this indemnity in respect of the business, operation and activities of Napo and NPIP to the extent such business, operation and activities of Napo and NPIP are the subject matter of a breach of the NPIP Warranties and/or Napo Warranties.

f) Napo shall ensure that NPIP enjoys the benefit of suitable director and officers insurance policy to cover its employees and directors and such director and officers insurance policy will not be terminated without the consent of the Investor.

b) Arbitration. In the case of any dispute or claim arising out of or in connection with or relating to this Agreement, or the breach, termination or invalidity hereof, the Parties shall attempt to first resolve such dispute or claim through discussions between senior executives of each Party.

The two arbitrators so appointed shall appoint the third arbitrator as may be mutually agreed amongst them. All arbitration proceedings shall be conducted in the English language and the place of arbitration shall be in Mumbai. The Parties shall be entitled to seek injunctive reliefs from the courts of India having jurisdiction. The arbitrators shall decide any such dispute or claim strictly in accordance with the governing law specified in Clause 16(a). Judgement upon any arbitral award rendered hereunder may be entered in any court having jurisdiction, or application may be made to such court for a judicial acceptance of the award and an order of enforcement, as the case may be.

c) Good Faith. Each Party shall co-operate in good faith to expedite (to the maximum extent practicable) the conduct of any arbitral proceedings commenced under this Agreement.

d) Costs and Expenses.

The Arbitration Board would have the power to award interest on any sum awarded pursuant to the arbitration proceedings and such sum would carry interest, if awarded, until the actual payment of such amounts.

e) Final and Binding. Subject to applicable Law, any award made by the Arbitration Board shall be final and binding on each of the Parties that were parties to the dispute.

17) TERM

18) MISCELLANEOUS

a) Amendment: This Agreement may not be amended, modified or supplemented except by a written instrument executed by Napo, NPIP, and Investors.

b) 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 another Party of any provision hereof shall be deemed to be a waiver of any subsequent breach of that or any other provision hereof.

c) Assignment: Neither this Agreement nor any of the rights or obligations hereunder shall be assignable, except with the mutual written consent of Napo, NPIP and the Investor. Provided that upon a transfer by the Investor of its OCRPSs and Shares (including Converted Shares) to a Person in accordance with this Agreement, it shall have the right to assign all its rights and obligations under this Agreement to such Person except the board rights or affirmative rights pursuant to Clause 9 unless the transfer is to an Affiliate.

d) Entire Agreement: This Agreement, any Investor Subscription Agreements and the schedules and annexures attached hereto constitute the entire agreement and understanding between the Parties with respect to the subject matters herein, and supersede and replace any prior agreements and understandings, whether oral or written between and among them with respect to such matters.

e) 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 the remainder of this Agreement.

f) Counterparts and Facsimile Signatures: This Agreement may be executed in one or more counterparts which, signed and taken together, shall constitute one document. A facsimile signature on this Agreement, if legible and complete, will be regarded as an original signature.

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