(c) Each International Underwriter and each International Placement Agent, severally and not jointly, will indemnify and hold harmless the Company, the Company’s directors and officers and the Selling Shareholder against any losses, claims, damages or liabilities to which the Company or the Selling Shareholder may become subject, under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Base Prospectus, any Preliminary Prospectus, the Pricing Prospectus or the Prospectus, or any amendment or supplement thereto, or any Issuer Free Writing Prospectus, or any roadshow, or any Testing-the-Waters Communication, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in the Registration Statement, the ADS Registration Statement, the Base Prospectus, any Preliminary Prospectus, the Pricing Prospectus or the Prospectus or any such amendment or supplement thereto, or any Issuer Free Writing Prospectus, or any roadshow or any Testing-the-Waters Communication, in reliance upon and in conformity with the Underwriter Information; and will reimburse the Company and the Selling Shareholder for any documented legal or other expenses reasonably incurred by the Company or the Selling Shareholder in connection with investigating or defending any such action or claim as such expenses are incurred. As used in this Agreement with respect to an International Underwriter or International Placement Agent and an applicable document, “Underwriter Information” shall mean the written information furnished to the Company by such International Underwriter or such International Placement Agent through the Representatives expressly for use therein; it being understood and agreed upon that the only such information furnished by any International Underwriter or any International Placement Agent consists of the following information in the Prospectus furnished on behalf of each International Underwriter: the name of such International Underwriter and/or International Placement Agent and the information contained in the 23^rd paragraph under the caption “Underwriting”; provided further that the liability of each International Underwriter and each International Placement Agent, pursuant to this Section 11(c), shall in no event exceed, in the aggregate, the discounts and commissions (net of taxes) received by such International Underwriter or such International Placement Agent (as the case may be) from the offering, sale and/or placement of the Securities.

(d) Promptly after receipt by an indemnified party under subsection (a), (b) or (c) above of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under such subsection, notify the indemnifying party in writing of the commencement thereof; provided that the failure to notify the indemnifying party shall not relieve it from any liability that it may have under the preceding paragraphs of this Section 11 except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided further that the failure to notify the indemnifying party shall not relieve it from any liability that it may have to an indemnified party otherwise than under the preceding paragraphs of this Section 11. In case any such action shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party) to represent the indemnified party in such proceeding and shall pay the fees and expenses of such counsel related to such proceeding, as incurred. Notwithstanding the above, each indemnified party shall have the right to employ its own counsel in any such case, but the fees and expenses of such counsel shall be at the expense of the indemnified party, unless (i) the indemnifying person and the indemnified person shall have mutually agreed to the contrary; (ii) the indemnifying person has failed within a reasonable time to retain counsel reasonably satisfactory to the indemnified person; (iii) the indemnified person shall have reasonably concluded that there may be legal defenses available to it that are different from or in addition to those available to the indemnifying person; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the indemnifying person and the indemnified person and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them, provided that the indemnifying party shall not be responsible for paying the fees of more than one international and one Brazilian counsel for the indemnified party. After notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party shall not be liable to such indemnified party under such subsection for any legal expenses of other counsel or any other expenses, in each case subsequently incurred by such indemnified party, in connection with the defense thereof other than reasonable costs of investigation. The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent, such consent not to be unreasonably withheld, but if settled with such consent, the indemnifying party agrees to indemnify the indemnified party from and against any loss or liability by reason of such settlement. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested that an indemnifying party reimburse the indemnified party for fees and expenses of counsel as contemplated by this Section 11(d) hereof, the indemnifying party shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 30 days after receipt by the indemnifying party of such request and (ii) the indemnifying party shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement. No indemnifying party shall, without the written consent of the indemnified party, effect the settlement or compromise of, or consent to the entry of any judgment with respect to, any pending or threatened action or claim in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified party is an actual or potential party to such action or claim) unless such settlement, compromise or judgment (i) includes an unconditional release of the indemnified party from all liability arising out of such action or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act, by or on behalf of any indemnified party.

(e) If the indemnification provided for in this Section 11 is unavailable to or insufficient to hold harmless an indemnified party under subsection (a), (b) or (c) above in respect of any losses, claims, damages or liabilities (or actions in respect thereof) referred to therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions in respect thereof) in such proportion as is appropriate to reflect the relative benefits received by the Selling Shareholder on the one hand and the International Underwriters and the International Placement Agents on the other from the offering of the Securities. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law, then each indemnifying party shall contribute to such amount paid or payable by such indemnified party in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company and the Selling Shareholder on the one hand and the International Underwriters and International Placement Agents on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities (or actions in respect thereof), as well as any other relevant equitable considerations. The relative benefits received by the Selling Shareholder on the one hand and the International Underwriters and International Placement Agents, severally and not jointly, on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (after underwriting discounts but before deducting expenses and taxes payable by the Selling Shareholder (as applicable)) received by the Selling Shareholder bear to the total underwriting discounts and commissions received by the International Underwriters and International Placement Agents, in each case as set forth in the table on the cover page of the Prospectus. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or the Selling Shareholder on the one hand or the International Underwriters and International Placement Agents on the other and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company, the Selling Shareholder and the International Underwriters and International Placement Agents agree that it would not be just and equitable if contribution pursuant to this subsection (e) were determined by pro rata allocation (even if the International Underwriters and International Placement Agents were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to above in this subsection (e). The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to above in this subsection (e) shall be deemed to include any documented legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this subsection (e), (i) no International Underwriter or International Placement Agent shall be required to contribute any amount in excess of the amount by which (x) the underwriting discount and commission (net of taxes and non-reimbursable expenses) received by such International Underwriter or such International Placement Agent (as the case may be) exceeds (y) the amount of any damages which such International Underwriter or such International Placement Agent has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission; and (ii) the Selling Shareholder shall not be required to contribute any amount in excess of the amount by which (x) the gross proceeds (less underwriting discounts but before other expenses and taxes payable by the Selling Shareholder) received by the Selling Shareholder from the offering, placement and/or sale of its Securities contemplated hereunder exceeds (y) the amount of any damages which the Selling Shareholder has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The International Underwriters' and International Placement Agents’ obligations in this subsection (e) to contribute are several in proportion to their respective obligations and not joint. For purposes of this subsection (e), (i) each person who controls the International Underwriters or the International Placement Agents within the meaning of either the Securities Act or the Exchange Act and each affiliate, director, officer, employee and agent of any International Underwriter or International Placement Agent shall have the same rights to contribution as such International Underwriter or International Placement Agent, (ii) each person who controls the Company within the meaning of either the Securities Act or the Exchange Act and each officer and director of the Company shall have the same rights to contribution as the Company, and (iii) each legal representative of the Selling Shareholder shall have the same rights to contribution as the Selling Shareholder, subject in each case to the applicable terms and conditions of this paragraph (e).

(f) The obligations of the Company and the Selling Shareholder under this Section 11 shall be in addition to any liability which the Company and the Selling Shareholder may otherwise have and shall extend, upon the same terms and conditions, to each employee, officer and director of each International Underwriter and International Placement Agent, each person, if any, who controls any International Underwriter or any International Placement Agent within the meaning of the Securities Act and each broker-dealer or other affiliate of any International Underwriter or any International Placement Agent; and the obligations of the International Underwriters and the International Placement Agents under this Section 11 shall be in addition to any liability which the respective International Underwriters or International Placement Agents may otherwise have and shall extend, upon the same terms and conditions, to each officer and director of the Company and to each person, if any, who controls the Company within the meaning of the Securities Act.

12. (a) If any International Underwriter shall default in its obligation to purchase the Securities which it has agreed to purchase hereunder, you may in your discretion arrange for you or another party or other parties to purchase such Securities on the terms contained herein. If within thirty-six hours after such default by any International Underwriter you do not arrange for the purchase of such Securities, then the Company and the Selling Shareholder shall be entitled to a further period of thirty-six hours within which to procure another party or other parties satisfactory to you to purchase such Securities on such terms. In the event that, within the respective prescribed periods, you notify the Company and the Selling Shareholder that you have so arranged for the purchase of such Securities, or the Company or the Selling Shareholder notifies you that it has so arranged for the purchase of such Securities, you or the Company or the Selling Shareholder shall have the right to postpone the Time of Delivery for a period of not more than seven days, in order to effect whatever changes may thereby be made necessary in the ADS Registration Statement, Registration Statement or the Prospectus, or in any other documents or arrangements, and the Company agrees to file promptly any amendments or supplements to the ADS Registration Statement, the Registration Statement or the Prospectus which in your opinion may thereby be made necessary. The term “International Underwriter” as used in this Agreement shall include any person substituted under this Section 12 with like effect as if such person had originally been a party to this Agreement with respect to such Securities.

(b)       If, after giving effect to any arrangements for the purchase of the Securities of a defaulting International Underwriter or International Underwriters by you, the Company or the Selling Shareholder as provided in subsection (a) above, the aggregate number of such Securities which remains unpurchased does not exceed one eleventh of the aggregate number of all the Securities, then the Selling Shareholder shall have the right to require each non-defaulting International Underwriter to purchase the number of shares which such International Underwriter agreed to purchase hereunder and, in addition, to require each non-defaulting International Underwriter to purchase its pro rata share (based on the number of Securities which such International Underwriter agreed to purchase hereunder) of the Securities of such defaulting International Underwriter or International Underwriters for which such arrangements have not been made; but nothing herein shall relieve a defaulting International Underwriter from liability for its default.

(c)       If, after giving effect to any arrangements for the purchase of the Securities of a defaulting International Underwriter or International Underwriters by you, the Company and the Selling Shareholder as provided in subsection (a) above, the aggregate number of such Securities which remains unpurchased exceeds one eleventh of the aggregate number of all the Securities, or if the Company and the Selling Shareholder shall not exercise the right described in subsection (b) above to require non-defaulting International Underwriters to purchase Securities of a defaulting International Underwriter or International Underwriters, then this Agreement shall thereupon terminate, without liability on the part of any non-defaulting International Underwriter, the Company or Selling Shareholder, except for the expenses to be borne by the Company, the Selling Shareholder and the International Underwriters as provided in Section 9 hereof and the indemnity and contribution agreements in Section 11 hereof; but nothing herein shall relieve a defaulting International Underwriter from liability for its default.

13. The respective indemnities, rights of contribution, agreements, representations, warranties and other statements of the Company, the Selling Shareholder and the several International Underwriters and International Placement Agents, as set forth in this Agreement or made by or on behalf of them, respectively, pursuant to this Agreement, shall remain in full force and effect, regardless of any investigation (or any statement as to the results thereof) made by or on behalf of any International Underwriter, International Placement Agent or any director, officer, employee, affiliate or controlling person of any International Underwriter or International Placement Agent, or the Company, or any officer or director or controlling person of the Company, or the Selling Shareholder and shall survive delivery of and payment for the Securities.

14. If this Agreement shall be terminated pursuant to Section 12 hereof, neither the Company nor the Selling Shareholder shall then be under any liability to any International Underwriter or International Placement Agent except as provided in Sections 9 and 11 hereof; but, if for any other reason, the Securities are not delivered by or on behalf of the Selling Shareholder as provided herein, the Selling Shareholder will reimburse the International Underwriters and the International Placement Agents through you for all out of pocket expenses approved in writing by you incurred by the International Underwriters and International Placement Agents in making preparations for the purchase, sale and delivery of the Securities, but the Company and the Selling Shareholder shall then be under no further liability to any International Underwriter except as provided in Sections 9 and 11 hereof.

15. In all dealings hereunder, you shall act on behalf of each of the International Underwriters and International Placement Agents, and the parties hereto shall be entitled to act and rely upon any statement, request, notice or agreement on behalf of any International Underwriter or any International Placement Agent made or given by you jointly or by Banco BTG Pactual S.A. — Cayman Branch, BofA Securities, Inc., Citigroup Global Markets Inc., UBS Securities LLC and Itau BBA USA Securities, Inc. on behalf of you as the representatives.

Dear Sirs:

Companhia de Saneamento Básico do Estado de São Paulo – SABESP, a mixed capital company (sociedade de economia mista) organized under the laws of the Federative Republic of Brazil (the “Company”), understands that you, as Representatives of the International Underwriters and the International Placement Agents, propose to enter into an Underwriting and Placement Facilitation Agreement (the “Underwriting Agreement”) with the Company providing for the public offering (the “International Offering”) by the International Underwriters, of common shares of the Company in the form of American Depositary Shares (the “ADSs”), each representing one common share of the Company (the “Underlying Shares”). In addition, in connection with a Brazilian Underwriting Agreement, among the Company and the Brazilian Underwriters named therein (the “Brazilian Underwriters”), relating to the public sale of common shares of the Company (the “Shares” and, together with the Underlying Shares, the “Common Shares”) in and outside Brazil (together with the International Offering, the “Global Offering”), the Company understands that the International Placement Agents expect to act as agents to the Brazilian Underwriters for the facilitation of the placement of Shares outside Brazil.
