CENTRAL SAN CENTRAL SAN BOARD OF DIRECTORS -- POSITION PAPER CENTRAL CONTRA COSTA SANITARY DISTRICT MEETING DATE: AUGUST 2, 2018 SUBJECT: CONSIDER ADOPTING RESOLUTION N0. 2018-015 AUTHORIZING CENTRAL SAN TO ISSUE REVENUE BONDS TO REFINANCE EXISTING DEBT TO TAKE ADVANTAGE OF INTEREST COST SAVINGS SUBMITTED BY: INITIATING DEPARTMENT: PHILIP R. LEIBER, DIRECTOR OF FINANCE ADMINISTRATION-FINANCE AND ADMINISTRATION REVIEWED BY: THEAVASSALLO, FINANCE MANAGER Deputy General Mgr.Ann Sasaki for General Manager Roger S. Bailey ISSUE Per Board Policy 029 - Debt Management and Continuing Disclosure, Board approval is required for the issuance of bonds that will refinance the existing 2009 Certificates of Participation. BACKGROUND At previous Finance Committee and Board meetings, staff has discussed refinancing Central San's 2009 outstanding debt. The Financing Team, appointed by the Board on July 5, 2018, has worked to resolve outstanding issues in the proposed refinancing. The documents presented in this package reflect the final proposed structure of the refinancing, and they are proposed for Board approval. The refunding is currently anticipated to save $2.428 million (present value) in interest costs through 2029. Actual savings will be reported to the Board after the issuance. August 2, 2018 Regular Board Meeting Agenda Packet- Page 29 of 253 Page 2 of 183 ssues noted as outstanding as of the last Finance Committee meeting, and their proposed treatment are as follows: • Whether to issue Certificates of Participation ("COP")or Revenue Bonds Revenue Bonds issued directly by Central San are proposed and the documents reflect this approach. Revenue Bonds are viewed as a more cost effective structure than CO Ps over the longer term. • Whether to proceed with refinancing only on the Series 2009A bonds or, in addition, the Series 2009B bonds Staff recommends proceeding with refinancing both series of bonds. Proceeding with refinancing the Series 2009B bonds will provide incremental savings of$157,976 and move Central San fully toward a revenue bond structure which is viewed as preferable in the long term due to potential future investor concerns about a more complicated COP structure. The bond structure reflects the following guidance previously provided by the Finance Committee and the Board: • Maintain generally the same debt amortization profile as the existing debt. • Proceed with only one credit rating on the refunding debt. • Review the need for the debt service reserve fund (DSRF)on new debt with consideration of issues surrounding the priority and security of Ad Valorem Property Tax. This issue has been discussed with District Counsel and Bond Counsel. Proceeding without a DSRF on the new bonds does not adversely affect legal arguments that could be raised in the event of potential State actions affecting Ad Valorem Property Tax. • Consider approvals, if necessary, by the Central Contra Costa Sanitary District Facilities Financing Authority. No approvals are necessary. Other structuring and transaction execution issues resolved by the Financing Team and proposed for acceptance by the Board include: • The manner in which the existing bonds will be retired As the bonds are not subject to a standard optional redemption until September 1, 2019, the typical approach would be to establish an escrow account with refunding bond proceeds sufficient in amount to call the bonds on that date. Establishing this escrow account allows for the bonds to be d efeased/re moved as obligations from Central San's books, even prior to the call date of September 1, 2019. There are costs to establishing the escrow account, and costs involved in borrowing funds from the new bonds, and buying securities that yield a lower return than the interest cost of the refunding bonds. So, it is not an optimal structure, but one that is workable and allowable given the Federal Tax legislation that prohibited most tax-exempt advance refundings. Such an approach still provides for estimated overall interest savings of about$1.4 million on a net present value basis. Alternatively and preferably, the existing bond documents have a provision allowing for the extraordinary redemption of the 2009A bonds at par, even prior to the September 1, 2019 call date based on the reduction in the Build America Bonds ("BAB")subsidy. The Financing Team and Bond Counsel have determined that exercising this provision is viable, and doing so will offer the possibility of significant additional refunding savings (a total of$2.428 million in present value savings, or about$1 million higher)versus the escrow approach. The rationale for exercising the extraordinary redemption provision includes the Federal Government's reduced subsidy(which has been curtailed by about 6 to 8% in recent years)for the BAB that has been affected by the Federal sequestration due to spending/deficit limitations. The 2009A bonds are expected to be redeemed August 2, 2018 Regular Board Meeting Agenda Packet- Page 30 of 253 Page 3 of 183 on September 10, 2018. The 20096 bonds, which are not subject to the extraordinary redemption provision, will be advance refunded on a taxable basis using the escrow account approach and will be redeemed on September 1, 2019. • No Debt Service Reserve Fund (DSRF), and inclusion of an optional Rate Stabilization Fund (RSF) The existing Certificates of Participation have a required DSRF that was funded with borrowed funds. The Underwriter, Financial Advisor and Bond Counsel have indicated that the bond market does not require a dedicated DSRF for a highly rated issue like Central San. Eliminating the DSRF allows for the issuance of a lesser amount of refunding bonds, and avoids the issue of negative arbitrage where money is borrowed and invested at a lower rate. Accordingly, the proposed bond documents do not provide for a DSRF. I n lieu of a DSRF, the new bond documents allow for(but do not mandate)the establishment of a Rate Stabilization Fund (RS F). A RSF could provide for some additional assurance of the payment of debt service if available revenues in a given year prove insufficient to cover debt service. This is a highly unlikely event as Central San's revenues are very predictable, and the financial policies provide for rates to be set to provide at least two times debt service coverage. As discussed in the bond documents, the RSF is not required to be established or funded at a particular level but, if established, moneys could flow into and out of the fund as available, or needed. For years in which a surplus of funds were available, monies could be deposited into the RSF. Then, funds from the RSF could be drawn down if net revenues were otherwise insufficient to cover debt service. Central San could make contributions to the RS F from favorable budget variances. Staff may at a future date propose changes to the Fiscal Reserve Policy(BP 017)to specify the establishment and workings of this fund apart from the language provided in the Bond I ndenture. However as the bond documents do not commit Central San to establish a RSF, this is at the discretion of Central San, and no action is required to be taken on an RSF now, or later. In summary, the refinancing will be executed with the issuance of two series of refunding bonds, with an expected closing the week of September 10, 2018: • Series 2018A (Final maturity: September 1, 2029) in the amount of approximately$15.3 million in tax-exempt Wastewater Revenue Refunding with proceeds used to refund $19.635 million outstanding 2009A Wastewater Revenue Certificates of Participation (Taxable Build America Bonds). • Series 2018B (Final maturity: September 1, 2023) in the amount of approximately$4.3 million in taxable Wastewater Revenue Refunding Bonds with proceeds used to advance refund the outstanding $6.98 million 2009B Wastewater Revenue Certificates of Participation. Staff requests that the Finance Committee recommend Board adoption of the attached proposed Revenue Bond Issuance Resolution as more fully described below: The resolution provides for the following: 1. Authorization for the issuance of Refunding Bonds; 2. Approval of Indenture. The Indenture is the legal contract specifying the important features of bonds, such as its maturity date, timing of interest payments, method of interest calculation, and security for the bonds; 3. Refinancing of the 2009 Certificates; 4. Sale of Refunding Bonds via negotiated sale to Piper Jaffray under the terms of the Bond Purchase Contract; August 2, 2018 Regular Board Meeting Agenda Packet- Page 31 of 253 Page 4 of 183 5. Approval of the preliminary Official Statement. This document is the description of the bonds provided to prospective investors and consists of several parts: (a)description of the bonds and the legal documents governing them; (b)description of the District; and (c)the most recently available audited financial statements of Central San; 6. Approval of the Continuing Disclosure Certificate. This document commits Central San to publish annually certain information to bondholders; 7. Adoption of documents in substantially final form. This specifies that the documents are in substantially final form, except for numbers which are subject to the results of the bond sale; and 8. Authorizes the President of the Board, the General Manager, the Director of Finance and Administration, and any and all other officers of Central San to take any and all actions to consummate the transactions described. Staff and Financing Team members will be available to answer questions at the meeting. ALT ERNAT IVES/CONSIDERATIONS Do not refinance the bonds. FINANCIAL IMPACTS The current projected savings for refinancing both series of bonds is $2,428,188, consisting of $2,270,212 for Series 2009A and $157,976 for Series 2009B. This is from the underwriter's estimate of refunding savings, net of issuance costs, shown at Attachment 6. This analysis has been confirmed by the Financial Advisor(PFM). This is nearly$1 million above the previous estimate, due to the Financing Team's consideration and Bond Counsel's approval of a more efficient way to execute the retirement of existing bonds (through an extraordinary call), as described in the Background section above. Based on the net present value savings apportioned by year through 2029, this is anticipated to result in a potential reduction in the Sewer Service Charge of approximately$1.50 per year through 2029 (ranging from about$2 per year in the first five years and declining to about 40 cents in 2029 as the amount of bonds outstanding declines). The savings are higher on a gross basis each year. COMMITTEE RECOMMENDATION The Finance Committee reviewed this matter at its meeting on J my 24, 2018 and recommended Board approval of the Revenue Bond Issuance Resolution, authorizing Central Santo issue revenue bonds to refinance existing debt to take advantage of interest cost savings. RECOMMENDED BOARD ACTION Staff recommends adopting Resolution No. 2018-015 authorizing Central San to issue revenue bonds to refinance existing debt to take advantage of interest cost savings.

Any notice of redemption shall be cancelled and annulled if for any reason funds will not be or are not available on the date fixed for redemption for the payment in full of the Bonds then called for redemption, and such cancellation shall not constitute an Event of Default. The District and the Trustee have no liability to the Bond Owners or any other party related to or arising from such rescission of notice of redemption. The Trustee shall mail notice of such rescission of notice of redemption in the same manner as the original notice of redemption was sent under Section 2.03. (h) Deposit of Money. On or prior to any redemption date, the District shall deposit with the Trustee an amount of money sufficient to pay the Redemption Price of all the Bonds or portions of Bonds which are to be redeemed on that date. (i) Consequences of Notice.

(1) Purchase of Bonds in lieu of Redemption.

The par amount of any of such Bonds so purchased by the District in any twelve-month period ending on January 1 in any year shall be credited towards and shall reduce the paramount of such Bonds required to be redeemed pursuant to Section 2.03(b) on the next succeeding September 1. All Bonds redeemed pursuant to this Section and all Bonds purchased by the District pursuant to this subsection (1)shall be cancelled and destroyed pursuant to Section 9.07. SECTION 2.04. Book Entry System. (a) Original Delivery. The Bonds will be initially delivered in the form of a separate single fully registered bond (which may be typewritten) for each maturity of each series of Bonds. Upon initial delivery, the Trustee shall register the ownership of each Bond on the Registration Books in the name of the Nominee. Except as provided in subsection (c), the ownership of all of the Outstanding Bonds shall be registered in the name of the Nominee on the Registration Books. With respect to Bonds the ownership of which is registered in the name of the Nominee, the District and the Trustee has no responsibility or obligation to any Depository System Participant or to any person on behalf of which the Nominee holds an interest in the Bonds. Without limiting the generality of the immediately preceding sentence, the District and the Trustee has no responsibility or obligation with respect to (i) the accuracy of the records of the Depository, the Nominee or any Depository System Participant with respect to any ownership interest in the Bonds, (ii) the delivery to any Depository System Participant or any other person, other than a Bond Owner as shown in the Registration Books, of any notice with respect to the Bonds, (iii) the selection by the Depository of the beneficial interests in the Bonds to be redeemed if the District elects to redeem the Bonds in part, (iv) the payment to any Depository System Participant or any other person, other than a Bond Owner as shown in the Registration Books, of any amount with respect to principal, interest and premium, if any, on the Bonds or (v) any consent given or other action taken by the Depository as Owner of the Bonds. The District and the Trustee may treat and consider the person in whose name each Bond is registered as the absolute owner of such Bond for the purpose of payment of principal of and the interest and premium, if any, on such Bond, for the purpose of giving notices of matters with respect to such Bond, for the purpose of registering transfers of ownership of such Bond, and for all other purposes whatsoever. The Trustee shall pay the principal of and the interest and -7- August 2, 2018 Regular Board Meeting Agenda Packet- Page 47 of 253 Page 20 of 183 premium, if any, on the Bonds only to the respective Owners or their respective attorneys duly authorized in writing, and all such payments shall be valid and effective to fully satisfy and discharge all obligations with respect to payment of principal of and interest and premium, if any, on the Bonds to the extent of the sum or sums so paid. No person other than a Bond Owner shall receive a Bond evidencing the obligation of the District to make payments of principal, interest and premium, if any, under this Indenture. Upon delivery by the Depository to the District of written notice to the effect that the Depository has determined to substitute a new Nominee in its place, and subject to the provisions herein with respect to Record Dates, such new nominee shall become the Nominee hereunder for all purposes; and upon receipt of such a notice the District shall promptly deliver a copy of the same to the Trustee. (b) Representation Letter. In order to qualify the Bonds for the Depository's book-entry system, the District shall execute and deliver to such Depository a letter representing such matters as shall be necessary to so qualify the Bonds. The execution and delivery of such letter shall not in any way limit the provisions of subsection (a) above or in any other way impose upon the District or the Trustee any obligation whatsoever with respect to persons having interests in the Bonds other than the Bond Owners. Upon the written acceptance by the Trustee, the Trustee shall agree to take all action reasonably necessary for all representations of the Trustee in such letter with respect to the Trustee to at all times be complied with. In addition to the execution and delivery of such letter, the District may take any other actions, not inconsistent with this Indenture, to qualify the Bonds for the Depository's book-entry program. (c) Transfers Outside Book-Entry, sem. If either(i)the Depository determines not to continue to act as Depository for the Bonds, or (ii) the District determines to terminate the Depository as such, then the District shall thereupon discontinue the book- entry system with such Depository. In such event, the Depository shall cooperate with the District and the Trustee in the issuance of replacement Bonds by providing the Trustee with a list showing the interests of the Depository System Participants in the Bonds, and by surrendering the Bonds, registered in the name of the Nominee, to the Trustee on or before the date such replacement Bonds are to be issued. The Depository, by accepting delivery of the Bonds, agrees to be bound by the provisions of this subsection (c). If, prior to the termination of the Depository acting as such, the District fails to identify another Securities Depository to replace the Depository, then the Bonds shall no longer be required to be registered in the Registration Books in the name of the Nominee, but shall be registered in whatever name or names the Owners transferring or exchanging Bonds shall designate, in accordance with the provisions hereof. If the District determines that it is in the best interests of the beneficial owners of the Bonds that they be able to obtain certificated Bonds, the District may notify the Depository System Participants of the availability of such certificated Bonds through the Depository. In such event, the Trustee will issue, transfer and exchange Bonds as required by the Depository and others in appropriate amounts; and whenever the Depository requests, the Trustee and the District shall cooperate with the Depository in taking appropriate action (i) to make available one or more separate certificates evidencing the Bonds to any Depository System Participant having Bonds credited to its account with the Depository, or(ii)to arrange for another Securities Depository to maintain custody of a single certificate evidencing such Bonds, all at the District's expense. -8- August 2, 2018 Regular Board Meeting Agenda Packet- Page 48 of 253 Page 21 of 183 (d) Payments to the Nominee. Notwithstanding any other provision of this Indenture to the contrary, so long as any Bond is registered in the name of the Nominee, all payments with respect to principal of and interest and premium, if any, on such Bond and all notices with respect to such Bond shall be made and given, respectively, as provided in the letter described in subsection (b) of this Section or as otherwise instructed by the Depository. SECTION 2.05. Form and Execution of Bonds. The Bonds, the form of Trustee's certificate of authentication, and the form of assignment to appear thereon, are set forth in Appendix B attached hereto and by this reference incorporated herein, with necessary or appropriate variations, omissions and insertions, as permitted or required by this Indenture. The President of the Board of Directors of the District (or his or her designee) shall execute, and the Secretary of the District shall attest each Bond. Either or both of such signatures may be made manually or may be affixed by facsimile thereof. If any officer whose signature appears on any Bond ceases to be such officer before the Closing Date, such signature will nevertheless be as effective as if the officer had remained in office until the Closing Date. Any Bond may be signed and attested on behalf of the District by such persons as at the actual date of the execution of such Bond are the proper officers of the District, duly authorized to execute debt instruments on behalf of the District, although on the date of such Bond any such person was not an officer of the District. Only those Bonds bearing a certificate of authentication in the form set forth in Appendix B, manually executed and dated by the Trustee, are valid or obligatory for any purpose or entitled to the benefits of this Indenture, and such certificate of the Trustee is conclusive evidence that such Bonds have been duly authenticated and delivered hereunder and are entitled to the benefits of this Indenture. SECTION 2.06. Transfer and Exchange of Bonds. (a) Transfer. Any Bond may, in accordance with its terms, be transferred, upon the Registration Books, by the person in whose name it is registered, in person or by a duly authorized attorney of such person, upon surrender of such Bond to the Trustee at its Office for cancellation, accompanied by delivery of a written instrument of transfer in a form acceptable to the Trustee, duly executed. The Trustee shall collect any tax or other governmental charge on the transfer of any Bonds under this Section 2.06. Whenever any Bond or Bonds shall be surrendered for transfer, the District shall execute and the Trustee shall authenticate and deliver to the transferee a new Bond or Bonds of like series, interest rate, maturity and aggregate principal amount. The District shall pay the cost of printing Bonds and any services rendered or expenses incurred by the Trustee in connection with any transfer of Bonds. The Trustee may refuse to transfer, under the provisions of this Section 2.06, either (a) any Bonds during the period 15 days prior to the date established by the Trustee for the selection of Bonds for redemption, or(b) any Bonds selected by the Trustee for redemption. (b) Exchange. The Bonds may be exchanged at the Office of the Trustee for a like aggregate principal amount of Bonds of other authorized denominations and of the same series, interest rate and maturity. The Trustee shall collect any tax or other governmental charge on the exchange of any Bonds under this subsection (b). The District shall pay the cost of printing Bonds and any services rendered or expenses -9- August 2, 2018 Regular Board Meeting Agenda Packet- Page 49 of 253 Page 22 of 183 incurred by the Trustee in connection with any exchange of Bonds. The Trustee may refuse to exchange, under the provisions of this Section 2.06, either (a) any Bonds during the 15 days prior to the date established by the Trustee for the selection of Bonds for redemption or (b) any Bonds selected by the Trustee for redemption. SECTION 2.07. Registration Books. The Trustee will keep or cause to be kept, at its Office, sufficient records for the registration and registration of transfer of the Bonds, which must at all times during normal business hours, and upon reasonable notice, be open to inspection by the District; and, upon presentation for such purpose, the Trustee shall, under such reasonable regulations as it may prescribe, register or transfer or cause to be registered or transferred, on the Registration Books, Bonds as hereinbefore provided. SECTION 2.08. Bonds Mutilated, Lost, Destroyed or Stolen. If any Bond is mutilated, the District, at the expense of the Owner of such Bond, shall execute, and the Trustee shall thereupon authenticate and deliver, a new Bond of like tenor in exchange and substitution for the Bond so mutilated, but only upon surrender to the Trustee of the Bond so mutilated. The Trustee shall cancel every mutilated Bond surrendered to it and deliver such mutilated Bond to, or upon the order of, the District. If any Bond is lost, destroyed or stolen, evidence of such loss, destruction or theft may be submitted to the Trustee and, if such evidence is satisfactory and if indemnity satisfactory to the Trustee is given, the District, at the expense of the Owner, shall execute, and the Trustee shall thereupon authenticate and deliver, a new Bond of like tenor in lieu of and in substitution for the Bond so lost, destroyed or stolen. The Trustee may require payment of a sum not exceeding the actual cost of preparing each new Bond issued under this Section and of the expenses which may be incurred by the Trustee in connection therewith. Any Bond issued under the provisions of this Section in lieu of any Bond alleged to be lost, destroyed or stolen will constitute an original additional contractual obligation on the part of the District whether or not the Bond so alleged to be lost, destroyed or stolen be at any time enforceable by anyone, and shall be equally and proportionately entitled to the benefits of this Indenture with all other Bonds issued under this Indenture. Notwithstanding any other provision of this Section 2.08, in lieu of delivering a new Bond for which principal has become due for a Bond which has been mutilated, lost, destroyed or stolen, the Trustee may make payment of such Bond in accordance with its terms upon receipt of indemnity satisfactory to the Trustee. -10- August 2, 2018 Regular Board Meeting Agenda Packet- Page 50 of 253 Page 23 of 183 ARTICLE III ISSUE OF BONDS; PARITY OBLIGATIONS SECTION 3.01.

Pledge of Tax Revenues and Net Revenues. The Bonds and all Parity Obligations are secured by a first pledge of and lien on all of the Tax Revenues and Net Revenues. In addition, the Bonds are secured by a pledge of all of the moneys in the Debt Service Fund, including all amounts derived from the investment of such moneys. The Bonds and any Parity Obligations are equally secured by a pledge, charge and lien upon the Tax Revenues and Net Revenues, without priority for series, issue, number or date, and the payment of the interest on and principal of the Bonds and Parity Obligations shall be and are secured by an exclusive pledge, charge and lien upon the Tax Revenues and Net Revenues. So long as any of the Bonds and Parity Obligations are Outstanding, the Tax Revenues, the Net Revenues and such moneys may not be used for any other purpose; except that out of the Tax Revenues and Net Revenues there may be apportioned such sums, for such purposes, as are expressly permitted by Section 4.02. SECTION 4.02. Receipt, Deposit and Application of Revenues. (a) Maintenance of Wastewater System Funds. The District has previously established the Wastewater System Funds, which it will continue to hold and maintain for the purposes and uses set forth herein. The District shall deposit all Tax Revenues and Gross Revenues in the Wastewater System Funds immediately upon receipt. (b) Application of Amounts in Wastewater System Funds. In addition to transfers which are required to be made for repayment of any Parity Obligations, the District shall withdraw amounts on deposit in the Wastewater System Funds and apply such amounts at the times and for the purposes, and in the priority, as follows: (i) Deposit and Application of Tax Revenues. On or before each Interest Payment Date, the District shall withdraw from the Wastewater System Funds and transfer to the Trustee for deposit in the Debt Service Fund (which the Trustee shall establish and hold in trust hereunder) an amount of Tax Revenues which, together with the balance then on deposit in the Debt Service Fund, is equal to the aggregate amount coming due and payable on the Bonds on the next succeeding Interest Payment Date. The District may not withdraw any Tax Revenues from the Wastewater System Funds in any Fiscal Year except for the purpose of making any payment to the Trustee as required by this subsection (i); provided, however, that at such time during any Fiscal Year as the amount of Tax Revenues on deposit in the Wastewater System Funds become equal to the aggregate amount of the debt service thereafter coming due and payable on the Bonds in such Bond Year, all remaining Tax Revenues received during such Fiscal Year will be released from the pledge and lien hereunder and may be used for any lawful purpose of the District. (ii) Deposit and Application of Net Revenues. If the amount of Tax Revenues transferred to the Trustee pursuant to the preceding clause -13- August 2, 2018 Regular Board Meeting Agenda Packet- Page 53 of 253 Page 26 of 183 (i) on or before each Interest Payment Date is less than the full amount required to be so transferred, the District shall withdraw Net Revenues from the Wastewater System Funds on such Interest Payment Date, and transfer to the Trustee for deposit in the Debt Service Fund, an amount equal to the amount of such insufficiency. (iii) No Preference or Priority. The District shall pay principal and interest on the Bonds and the principal of and interest on any Parity Obligations from the Tax Revenues and Net Revenues without preference or priority among the Bonds and Parity Obligations. If the amount of Tax Revenues and Net Revenues on deposit in the Wastewater System Funds is any time insufficient to enable the District to pay when due the principal and interest on the Bonds and the principal of and interest on the Parity Obligations, such payments shall be made on a pro rata basis. (iv) Other Uses of Wastewater System Funds. The District shall manage, conserve and apply moneys in the Wastewater System Funds in such a manner that all deposits required to be made under this Section and under any Parity Obligation Documents will be made at the times and in the amounts so required.

The District shall adopt all necessary budgets and make all necessary appropriations of the principal and interest due on the Bonds from the Tax Revenues and Net Revenues. If any such payment requires the adoption by the District of any supplemental budget or appropriation, the District shall promptly adopt the same. The covenants on the part of the District contained in this paragraph constitute duties imposed by law and it shall be the duty of each and every public official of the District to take such actions and do such things as are required by law in the performance of the official duty of such officials to enable the District to carry out and perform the covenants and agreements in this paragraph. SECTION 4.03. Establishment of Rate Stabilization Fund. The District may establish a fund to be held by it and administered in accordance with this Section 4.03, for the purpose of stabilizing the rates and charges imposed by the District with respect to the Wastewater System. From time to time the District may deposit amounts in the Rate Stabilization Fund, from any source of legally available funds, including but not limited to Tax Revenues and Net Revenues which are released from the pledge and lien which secures the Bonds and any Parity Obligations, as the District may determine. -14- August 2, 2018 Regular Board Meeting Agenda Packet- Page 54 of 253 Page 27 of 183 The District may, but is not required to, withdraw from any amounts on deposit in the Rate Stabilization Fund and deposit such amounts in the Wastewater System Funds in any Fiscal Year for the purpose of paying debt service on the Bonds coming due and payable in such Fiscal Year. Amounts so transferred from the Rate Stabilization Fund to the Wastewater System Funds shall constitute Gross Revenues for such Fiscal Year (except as otherwise provided herein), and shall be applied for the purposes of the Wastewater System Funds. Amounts on deposit in the Rate Stabilization Fund shall not be pledged to or otherwise secure the Bonds or any Parity Obligations. The District has the right at any time to withdraw any or all amounts on deposit in the Rate Stabilization Fund and apply such amounts for any lawful purposes of the District relating to the Wastewater System. SECTION 4.04. Investments. (a) Investment of Funds Held by District. All moneys in the Wastewater System Funds and the Rate Stabilization Fund shall be invested by the District from time to time in any securities in which the District may legally invest funds subject to its control. (b) Investment of Funds Held by Trustee. The Trustee shall invest moneys in the funds and accounts held by it hereunder in Permitted Investments specified in the Request of the District delivered to the Trustee at least two Business Days in advance of the making of such investments. The Trustee may rely conclusively upon the investment direction of the District as to the suitability and legality of the directed investments. In the absence of any such direction from the District, the Trustee shall invest any such moneys solely in Permitted Investments described in clause (e) of the definition thereof; provided, however, that any such investment shall be made by the Trustee only if, prior to the date on which such investment is to be made, the Trustee shall have received a Request of the District specifying a specific money market fund that satisfies the requirements of said paragraph in which such investment is to be made and, if no such Request of the District is so received, the Trustee shall hold such moneys uninvested. (c) General Investment Provisions. Obligations purchased as an investment of moneys in any fund or account shall be deemed to be part of such fund or account. Whenever in this Indenture the District is required to transfer any moneys to the Trustee, such transfer may be accomplished by transferring a like amount of Permitted Investments. All interest or gain derived from the investment of amounts in any of the funds or accounts held by the Trustee hereunder shall be retained in the respective fund or account from which such investment was made. For purposes of acquiring any investments hereunder, the Trustee may commingle funds held by it hereunder upon receipt by the Trustee of the Request of the District. The Trustee or an affiliate may act as principal or agent in the acquisition or disposition of any investment and may impose its customary charges therefor. The Trustee has no liability for losses arising from any investments made under this Section. The District acknowledges that to the extent regulations of the Comptroller of the Currency or other applicable regulatory entity grant the District the right to receive brokerage confirmations of security transactions as they occur, the District specifically waives receipt of such confirmations to the extent permitted by law. The Trustee will furnish the District periodic transaction statements which include detail for all investment transactions made by the Trustee hereunder. -15- August 2, 2018 Regular Board Meeting Agenda Packet- Page 55 of 253 Page 28 of 183 The Trustee or any of its affiliates may act as sponsor, advisor or manager in connection with any investments made by the Trustee hereunder. SECTION 4.05. Valuation and Disposition of Investments. (a) Except as otherwise provided in subsection (b) of this Section, the District covenants that all investments of amounts deposited in any fund or account created by or under this Indenture, or otherwise containing gross proceeds of the Bonds (within the meaning of Section 148 of the Tax Code) shall be acquired, disposed of and valued (as of the date that valuation is required by this Indenture or the Tax Code) at Fair Market Value as such term is defined in subsection (d) below. (b) Investments in funds or accounts (or portions thereof) that are subject to a yield restriction under applicable provisions of the Tax Code shall be valued at cost thereof (consisting of present value thereof within the meaning of Section 148 of the Tax Code); provided that the District must inform the Trustee which funds are subject to a yield restriction, and must provide the Trustee with any necessary valuation criteria or formulae. (c) Except as provided in the proceeding subsection (b), for the purpose of determining the amount in any fund, the Trustee shall value Permitted Investments credited to such fund at least annually at the Fair Market Value thereof, on September 1 of each year. The Trustee shall have no duty in connection with the determination of Fair Market Value other than to follow: (i) its normal practices in the purchase, sale and determining the value of Permitted Investments; and (ii) the investment directions of the District. The Trustee may utilize and rely on computerized securities pricing services that may be available to it, including those available through its regular accounting system. If and as directed by the District in writing, the Trustee shall sell or present for redemption any Permitted Investment so purchased by the Trustee whenever it is necessary to provide moneys to meet any required payment, transfer, withdrawal or disbursement from the fund to which such Permitted Investment is credited, and the Trustee has no liability or responsibility for any loss resulting therefrom. In determining the market value of Authorized Investments, the Trustee may use and rely conclusively and without liability upon any generally recognized pricing information service (including brokers and dealers in securities) available to it. (d) For purposes of this Section 4.05, the term "Fair Market Value" means the price at which a willing buyer would purchase the investment from a willing seller in a bona fide, arm's length transaction (determined as of the date the contract to purchase or sell the investment becomes binding) if the investment is traded on an established securities market (within the meaning of Section 1273 of the Tax Code) and, otherwise, the term "Fair Market Value" means the acquisition price in a bona fide arm's length transaction (as referenced above) if (i) the investment is a certificate of deposit that is acquired in accordance with applicable regulations under the Tax Code, (ii) the investment is an agreement with specifically negotiated withdrawal or reinvestment provisions and a specifically negotiated interest rate (for example, a guaranteed investment contract, a forward supply contract or other investment agreement) that is acquired in accordance with applicable regulations under the Tax Code, or (iii) the investment is a United States Treasury Security-- State and Local Government Series which is acquired in accordance with applicable regulations of the United States Bureau of Public Debt. -16- August 2, 2018 Regular Board Meeting Agenda Packet- Page 56 of 253 Page 29 of 183 ARTICLE V FINANCIAL COVENANTS SECTION 5.01. Punctual Payment; Compliance With Documents. The District shall punctually pay or cause to be paid the interest and principal to become due with respect to all of the Bonds in strict conformity with the terms of the Bonds and of this Indenture, and will faithfully observe and perform all of the conditions, covenants and requirements of this Indenture and all Supplemental Indentures. SECTION 5.02. Discharge of Claims. The District covenants that in order to fully preserve and protect the priority and security of the Bonds the District shall pay from the Tax Revenues and/or Net Revenues and discharge all lawful claims for labor, materials and supplies furnished for or in connection with the Wastewater System which, if unpaid, may become a lien or charge upon the Net Revenues prior or superior to the lien of the Bonds and impair the security of the Bonds. The District shall also pay, from the Tax Revenues and/or Net Revenues, all taxes and assessments or other governmental charges lawfully levied or assessed upon or in respect of the Wastewater System or upon any part thereof or upon any of the revenues derived therefrom. SECTION 5.03. Operation of Wastewater System in Efficient and Economical Manner. The District covenants and agrees to operate the Wastewater System in an efficient and economical manner and to operate, maintain and preserve the Wastewater System in good repair and working order. SECTION 5.04. Sale or Eminent Domain of Wastewater System. Except as provided herein, the District covenants that the Wastewater System will not be encumbered, sold, leased, pledged, any charge placed thereon, or otherwise disposed of, as a whole or substantially as a whole, if such encumbrance, sale, lease, pledge, charge or other disposition would materially impair the ability of the District to pay the principal of or interest on the Bonds or any Parity Obligations, or would materially adversely affect its ability to comply with the terms of this Indenture or any Parity Obligation Documents. The District may not enter into any agreement which impairs the operation of the Wastewater System or any part of it necessary to secure adequate Tax Revenues and Net Revenues to pay the Bonds and any Parity Obligations, or which otherwise would impair the rights of the Bond Owners with respect to the Tax Revenues and Net Revenues. The Net Proceeds received as awards as a result of the taking of all or any part of the Wastewater System by the lawful exercise of eminent domain, if and to the extent that such right can be exercised against such property of the District, shall either (a) be used for the acquisition or construction of improvements and extension of the Wastewater System, or (b) be applied on a pro rata basis to redeem the Bonds and any Parity Obligations in accordance with this Indenture and the related Parity Obligation Documents. SECTION 5.05. Insurance. The District will at all times maintain with responsible insurers all such insurance on the Wastewater System as is customarily maintained with respect to works and properties of like character against accident to, loss of or damage to the Wastewater System.

The Trustee has no liability to determine whether the District is in compliance with the provisions of this Section 5.05. The Net Proceeds collected by the District from insurance against accident to or destruction of any portion of the Wastewater System shall be used to repair or rebuild such damaged or destroyed portion of the Wastewater System, and to the extent not so applied, shall be applied on a pro rata basis to redeem the Bonds and any Parity Obligations in accordance with this Indenture and the related Parity Obligation Documents. SECTION 5.06. Records and Accounts. The District will keep proper books of record and accounts of the Wastewater System, separate from all other records and accounts, in which complete and correct entries shall be made of all transactions relating to the Wastewater System. Said books shall, upon reasonable request, be subject to the inspection of the Trustee and the Owners of not less than 10% of the Outstanding Bonds or their representatives authorized in writing. The District shall cause the books and accounts of the Wastewater System to be audited annually by an Independent Accountant and will make available for inspection by the Bond Owners at the Office of the Trustee, upon reasonable request, a copy of the report of such Independent Accountant. SECTION 5.07. Rates and Charges. (a) Net Revenues Covenant. The District agrees to prescribe, revise and collect charges for the services and facilities of the Wastewater System which, after allowances for contingencies and error in the estimates, produce Gross Revenues (excluding capacity fees) sufficient in each Fiscal Year to provide Net Revenues which, together with the amount of Tax Revenues estimated by the District to be received during such Fiscal Year, are at least equal to 125% of the sum of the aggregate amount of the principal of and interest on the Bonds and any Parity Obligations coming due and payable during such Fiscal Year. (b) Gross Revenues Covenant. The District further agrees to prescribe, revise and collect charges for the services and facilities of the Wastewater System which, after allowances for contingencies and error in the estimates, produce Gross Revenues (including, for clarity, capacity fees), sufficient in each Fiscal Year, together with the amount of Tax Revenues estimated by the District to be received during such Fiscal Year, to yield Gross Revenues at least equal to 100% of the sum of(i) the aggregate amount of the principal of and interest on the Bonds and any Parity Obligations coming due and payable during such Fiscal Year and (ii) estimated Operation and Maintenance Costs coming due and payable during such Fiscal Year. (c) Rate Stabilization Fund. For the purpose of computing the amount of Gross Revenues or Net Revenues for any Fiscal Year for purposes of this Section 5.07, the District shall be permitted to transfer amounts on deposit in the Rate Stabilization Fund for purposes of such computation (except that amounts that were transferred into the Rate Stabilization Fund from Gross Revenues and/or Tax Revenues received by the District in such Fiscal Year shall not be double-counted), and such transfers may be made until (but not after) 180 days after the end of such Fiscal Year. -18- August 2, 2018 Regular Board Meeting Agenda Packet- Page 58 of 253 Page 31 of 183 SECTION 5.08. Superior and Subordinate Obligations; Parity Obligations. The District shall not issue or incur any additional bonds or other obligations having any priority in payment of principal or interest out of the Tax Revenues, the Gross Revenues, or the Net Revenues over the Bonds. Nothing herein is intended or may be construed to limit or affect the ability of the District to issue or incur (a) Parity Obligations, or (b) obligations which are either unsecured or which are secured by an interest in the Tax Revenues or Net Revenues which is junior and subordinate to the pledge of and lien upon the Tax Revenues and Net Revenues established hereunder. Parity Obligations may be issued or incurred only in accordance with Sections 3.04 and 3.05. SECTION 5.09. Tax Covenants Relating to Bonds. (a) The District shall not take any action or permit to be taken any action within its control which would cause or which, with the passage of time if not cured would cause, interest on the Series A Bonds to become includable in gross income for federal income tax purposes. (b) The District shall assure that the proceeds of the Series A Bonds are not used in a manner which would cause the Series A Bonds to become "private activity bonds" within the meaning of section 141(a) of the Tax Code or to meet the private loan financing test of Section 141(c) of the Tax Code. (c) The District shall not take any action or permit or suffer any action to be taken if the result of the same would be to cause the Series A Bonds to be"federally guaranteed" within the meaning of Section 149(b) of the Tax Code. (d) The District shall not take, or permit or suffer to be taken by the Trustee or otherwise, any action with respect to the Series A Bond proceeds which, if such action had been reasonably expected to have been taken, or had been deliberately and intentionally taken, on the Closing Date, would have caused the Series A Bonds to be "arbitrage bonds" within the meaning of Section 148 of the Tax Code. (e) The District shall calculate or cause to be calculated all amounts of excess investment earnings with respect to the Series A Bonds which are required to be rebated to the United States of America under Section 148(f) of the Tax Code, at the times and in the manner required under the Tax Code. The District shall pay when due an amount equal to excess investment earnings to the United States of America in such amounts, at such times and in such manner as may be required under the Tax Code, such payments to be made from any source of legally available funds of the District. The District shall keep or cause to be kept, and retain or cause to be retained for a period of six years following the retirement of the Series A Bonds, records of the determinations made under this subsection (e). The Trustee has no duty to monitor the compliance by the District with any of the covenants contained in this Section 5.09. SECTION 5.10. Continuing Disclosure. The District will comply with and carry out all of the provisions of the Continuing Disclosure Certificate which has been executed and delivered by the District on the Closing Date. Notwithstanding any other provision hereof, failure of the District to comply with the Continuing Disclosure Certificate does not -19- August 2, 2018 Regular Board Meeting Agenda Packet- Page 59 of 253 Page 32 of 183 constitute an Event of Default hereunder; provided, however, that any Participating Underwriter (as such term is defined in the Continuing Disclosure Certificate) or any Owner or beneficial owner of the Bonds may take such actions as may be necessary and appropriate, including seeking specific performance by court order, to cause the District to comply with its obligations under this Section 5.10. SECTION 5.11. Further Assurances. The District will adopt, make, execute and deliver any and all such further resolutions, instruments and assurances as may be reasonably necessary or proper to carry out the intention or to facilitate the performance of this Indenture, and for the better assuring and confirming unto the Owners of the Bonds and the Trustee the rights and benefits provided in this Indenture. ARTICLE VI THE TRUSTEE SECTION 6.01. Duties, Immunities and Liabilities of Trustee. (a) Performance of Duties. The Trustee shall, prior to the occurrence of an Event of Default, and after the curing or waiving of all Events of Default which may have occurred, perform such duties and only such duties as are specifically set forth in this Indenture and no implied covenants or duties will be read into this Indenture against the Trustee. The Trustee shall, during the existence of any Event of Default (which has not been cured or waived), exercise such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in their exercise, as a reasonable corporate trustee would exercise or use. (b) Removal of Trustee. The District may remove the Trustee upon 30 days' prior written notice, and shall remove the Trustee (i) if at any time requested to do so by an instrument or concurrent instruments in writing signed by the Owners of not less than a majority in aggregate principal amount of the Bonds then Outstanding (or their attorneys duly authorized in writing) or (ii) if at any time the Trustee ceases to be eligible in accordance with subsection (e) of this Section 6.01, or becomes incapable of acting, or is adjudged a bankrupt or insolvent, or a receiver of the Trustee or its property is appointed, or any public officer takes control or charge of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation. The District may accomplish such removal by giving 30 days' prior written notice to the Trustee, whereupon the District will appoint a successor Trustee by an instrument in writing. (c) Resignation by Trustee. The Trustee may at any time resign by giving written notice of such resignation to the District, and by giving notice of such resignation by first class mail, postage prepaid, to the Bond Owners at their respective addresses shown on the Registration Books. Upon receiving such notice of resignation, the District will promptly appoint a successor Trustee by an instrument in writing. (d) Appointment of Successor Trustee. Any removal or resignation of the Trustee and appointment of a successor Trustee becomes effective upon acceptance of appointment by the successor Trustee. If no successor Trustee has been appointed and accepted appointment within 45 days following giving notice of removal or notice of resignation as aforesaid, the resigning Trustee, any Owner (on behalf of such Owner and -20- August 2, 2018 Regular Board Meeting Agenda Packet- Page 60 of 253 Page 33 of 183 all other Owners) may petition any federal or state court for the appointment of a successor Trustee, and such court may thereupon, after such notice (if any) as it may deem proper, appoint such successor Trustee. Any successor Trustee appointed under this Indenture shall signify its acceptance of such appointment by executing and delivering to the District and to its predecessor Trustee a written acceptance thereof, and such successor Trustee, without any further act, deed or conveyance, shall become vested with all the moneys, estates, properties, rights, powers, trusts, duties and obligations of such predecessor Trustee, with like effect as if originally named Trustee herein; but, nevertheless, upon the receipt by the predecessor Trustee of the Request of the District or the request of the successor Trustee, such predecessor Trustee shall execute and deliver any and all instruments of conveyance or further assurance and do such other things as may reasonably be required for more fully and certainly vesting in and confirming to such successor Trustee all the right, title and interest of such predecessor Trustee in and to any property held by it under this Indenture and shall pay over, transfer, assign and deliver to the successor Trustee any money or other property subject to the trusts and conditions herein set forth. Upon request of the successor Trustee, the District will execute and deliver any and all instruments as may be reasonably required for more fully and certainly vesting in and confirming to such successor Trustee all such moneys, estates, properties, rights, powers, trusts, duties and obligations. Upon acceptance of appointment by a successor Trustee as provided in this subsection, the District shall mail or cause the successor Trustee to mail, by first class mail postage prepaid, a notice of the succession of such Trustee to the trusts hereunder to each rating agency which then maintains a rating on the Bonds, and to the Owners at the addresses shown on the Registration Books. If the District fails to mail such notice within 15 days after acceptance of appointment by the successor Trustee, the successor Trustee shall cause such notice to be mailed at the expense of the District. (e) Qualifications of Trustee. Any Trustee appointed under the provisions of this Section in succession to the Trustee must: (i) be a company, national banking association or bank having trust powers, (ii) have a corporate trust office in the State of California, (iii) have (or be part of a bank holding company system whose bank holding company has) a combined capital and surplus of at least $75,000,000, and (iv) be subject to supervision or examination by federal or state authority. If such bank, national banking association or company publishes a report of condition at least annually, under law or to the requirements of any supervising or examining authority above referred to, then for the purpose of this subsection the combined capital and surplus of such bank, national banking association or company shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. In case at any time the Trustee shall cease to be eligible in accordance with the provisions of this subsection (e), the Trustee shall resign immediately in the manner and with the effect specified in subsection (c) of this Section. -21- August 2, 2018 Regular Board Meeting Agenda Packet- Page 61 of 253 Page 34 of 183 The District will maintain a Trustee which is qualified under the provisions of the foregoing provisions of this subsection (e), so long as any Bonds are Outstanding. SECTION 6.02. Merger or Consolidation. Any bank, national banking association or company into which the Trustee may be merged or converted or with which either of them may be consolidated or any bank, national banking association or company resulting from any merger, conversion or consolidation to which it shall be a party or any bank, national banking association or company to which the Trustee may sell or transfer all or substantially all of its corporate trust business, provided such bank, national banking association or company shall be eligible under subsection (e) of Section 6.01, shall be the successor to such Trustee without the execution or filing of any paper or any further act, anything herein to the contrary notwithstanding. SECTION 6.03. Rights and Liabilities of Trustee. (a) The recitals of facts herein and in the Bonds contained are taken as statements of the District, and the Trustee has no responsibility for the correctness of the same, nor does it have any liability whatsoever therefor, nor make any representations as to the validity or sufficiency of this Indenture or of the Bonds nor shall it incur any responsibility in respect thereof, other than as expressly stated herein. The Trustee is, however, responsible for its representations contained in its certificate of authentication on the Bonds. The Trustee is not liable in connection with the performance of its duties hereunder, except for its own negligence or willful misconduct. The Trustee is not liable for the acts of any agents of the Trustee selected by it with due care. The Trustee may become the Owner of any Bonds with the same rights it would have if it were not Trustee and, to the extent permitted by law, may act as depository for and permit any of its officers or directors to act as a member of, or in any other capacity with respect to, any committee formed to protect the rights of the Owners, whether or not such committee shall represent the Owners of a majority in principal amount of the Bonds then Outstanding. The Trustee, either as principal or agent, may engage in or be entrusted in any financial or other transaction with the District. (b) The Trustee has no liability with respect to any action taken or omitted to be taken by it in accordance with the direction of the Owners of a majority in aggregate principal amount of the Bonds at the time Outstanding relating to the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred upon the Trustee under this Indenture. (c) The Trustee has no liability for any action taken by it in good faith and believed by it to be authorized or within the discretion or rights or powers conferred upon it by this Indenture, except for actions arising from the negligence or willful misconduct of the Trustee. The permissive right of the Trustee to do things enumerated hereunder is not construed as a mandatory duty. (d) The Trustee will not be deemed to have knowledge of any Event of Default hereunder unless and until a responsible officer of the Trustee has actual knowledge thereof, or unless and until a responsible officer of the Trustee has received written notice thereof at its Office. Except as otherwise expressly provided herein, the Trustee is not bound to ascertain or inquire as to the performance or observance of any of the terms, conditions, covenants or agreements herein or of any of the documents executed in connection with the Bonds, or as to the existence of an Event of Default hereunder or -22- August 2, 2018 Regular Board Meeting Agenda Packet- Page 62 of 253 Page 35 of 183 thereunder. The Trustee is not responsible for the District's payment of principal and interest on the Bonds, the District's observance or performance of any other covenants, conditions or terms contained herein, or the validity or effectiveness of any collateral given to or held by it. Without limiting the generality of the foregoing, and notwithstanding anything herein to the contrary, the Trustee is not responsible for reviewing the contents of any financial statements furnished to the Trustee under Section 5.06 and may rely conclusively on a Certificate of the District (if any) to establish the District's compliance with its financial covenants hereunder, including, without limitation, its covenants regarding the deposit of Gross Revenues into the Wastewater System Funds and the investment and application of moneys on deposit in the Wastewater System Funds (other than its covenants to transfer such moneys to the Trustee when due hereunder). (e) No provision in this Indenture requires the Trustee to risk or expend its own funds or otherwise incur any financial liability hereunder. The Trustee is entitled to receive interest on any moneys advanced by it hereunder, at the maximum rate permitted by law. (f) The Trustee may establish additional accounts or subaccounts of the funds established hereunder as the Trustee deems necessary or prudent in furtherance of its duties under this Indenture. (g) The Trustee has no responsibility or liability whatsoever with respect to any information, statement, or recital in any official statement, offering memorandum or any other disclosure material prepared or distributed with respect to the Bonds, nor shall the Trustee have any obligation to review any such material, and any such review by the Trustee will not be deemed to create any obligation, duty or liability on the part of the Trustee. (h) At any and all reasonable times the Trustee, and its duly authorized agents, attorneys, experts, engineers, accountants and representatives, have the right(but not the duty) fully to inspect the Wastewater System, including all books, papers and records of the District pertaining to the Wastewater System and the Bonds, and to take such memoranda from and with regard thereto as may be desired but which is not privileged by statute or by law. (i) Before taking any action under Article VIII or this Article VI, the Trustee may require indemnity satisfactory to the Trustee be furnished to it to hold the Trustee harmless from any expenses whatsoever and to protect it against any liability it may incur hereunder. 0) The immunities extended to the Trustee also extend to its directors, officers, employees and agents. (k) The permissive right of the Trustee to do things enumerated in this Indenture is not construed as a duty. (1) The Trustee may execute any of the trusts or powers hereof and perform any of its duties through attorneys, agents and receivers and is not answerable for the conduct of the same if appointed by it with reasonable care. (m) The Trustee shall not be considered in breach of or in default in its obligations hereunder or progress in respect thereto in the event of enforced delay in the performance of such obligations due to unforeseeable causes beyond its control and without its fault or -23- August 2, 2018 Regular Board Meeting Agenda Packet- Page 63 of 253 Page 36 of 183 negligence, including, but not limited to, Acts of God or of the public enemy or terrorists, acts of a government, acts of the other party, fires, floods, epidemics, quarantine restrictions, strikes, freight embargoes, earthquakes, explosion, mob violence, riot, inability to procure or general sabotage or rationing of labor, equipment, facilities, sources of energy, material or supplies in the open market, litigation or arbitration involving a party or others relating to zoning or other governmental action or inaction pertaining to the project, malicious mischief, condemnation, and unusually severe weather or delays of suppliers or subcontractors due to such causes or any similar event and/or occurrences beyond the control of the Trustee. SECTION 6.04. Right to Rely on Documents. The Trustee is protected in acting upon any notice, resolution, requisition, request, consent, order, certificate, report, opinion, facsimile transmission, electronic mail or other paper or document believed by it to be genuine and to have been signed or presented by the proper party or parties. The Trustee may consult with counsel, including, without limitation, Bond Counsel or other counsel of or to the District, with regard to legal questions, and the opinion of such counsel shall be full and complete authorization and protection in respect of any action taken or suffered by the Trustee hereunder in accordance therewith. The Trustee is not bound to recognize any person as the Owner of a Bond unless and until such Bond is submitted for inspection, if required, and such person's title thereto is established to the satisfaction of the Trustee. Whenever in the administration of the trusts imposed upon it by this Indenture the Trustee deems it necessary or desirable that a matter be proved or established prior to taking or suffering any action hereunder, such matter (unless other evidence in respect thereof be herein specifically prescribed) may be deemed to be conclusively proved and established by a Certificate of the District, which shall be full warrant to the Trustee for any action taken or suffered in good faith under the provisions of this Indenture in reliance upon such Certificate, but in its discretion the Trustee may (but has no duty to), in lieu thereof, accept other evidence of such matter or may require such additional evidence as to it may deem reasonable. The Trustee may conclusively rely on any certificate or report of any Independent Accountant appointed by the District. The Trustee shall have the right to accept and act upon instructions, including funds transfer instructions ("Instructions") given pursuant to this Indenture and delivered using Electronic Means ("Electronic Means" means the following communications methods: e-mail, facsimile transmission, secure electronic transmission containing applicable authorization codes, passwords and/or authentication keys issued by the Trustee, or another method or system specified by the Trustee as available for use in connection with its services hereunder); provided, however, that the District shall provide to the Trustee an incumbency certificate listing officers with the authority to provide such Instructions ("Authorized Officers") and containing specimen signatures of such Authorized Officers, which incumbency certificate shall be amended by the District, whenever a person is to be added or deleted from the listing. If the District elects to give the Trustee Instructions using Electronic Means and the Trustee in its discretion elects to act upon such Instructions, the Trustee's understanding of such Instructions shall be deemed controlling. The District understands and agrees that the Trustee cannot determine the identity of the actual sender of such Instructions and that the Trustee shall conclusively presume that directions that purport to have been sent by an Authorized Officer listed on the incumbency certificate provided to the Trustee have been sent by -24- August 2, 2018 Regular Board Meeting Agenda Packet- Page 64 of 253 Page 37 of 183 such Authorized Officer. The District shall be responsible for ensuring that only Authorized Officers transmit such Instructions to the Trustee and that the District and all Authorized Officers are solely responsible to safeguard the use and confidentiality of applicable user and authorization codes, passwords and/or authentication keys upon receipt by the District. The Trustee shall not be liable for any losses, costs or expenses arising directly or indirectly from the Trustee's reliance upon and compliance with such Instructions notwithstanding such directions conflict or are inconsistent with a subsequent written instruction. The District agrees: (i) to assume all risks arising out of the use of Electronic Means to submit Instructions to the Trustee, including without limitation the risk of the Trustee acting on unauthorized Instructions, and the risk of interception and misuse by third parties; (ii) that it is fully informed of the protections and risks associated with the various methods of transmitting Instructions to the Trustee and that there may be more secure methods of transmitting Instructions than the method(s) selected by the District; (iii) that the security procedures (if any) to be followed in connection with its transmission of Instructions provide to it a commercially reasonable degree of protection in light of its particular needs and circumstances; and (iv) to notify the Trustee immediately upon learning of any compromise or unauthorized use of the security procedures. The Trustee shall not be concerned with or accountable to anyone for the subsequent use or application of any moneys which shall be released or withdrawn in accordance with the provisions hereof. SECTION 6.05. Preservation and Inspection of Documents. All documents received by the Trustee under the provisions of this Indenture shall be retained in its possession and shall be subject during normal business hours, and upon reasonable prior written notice, to the inspection of the District and any Owner, and their agents and representatives duly authorized in writing. SECTION 6.06. Compensation and Indemnification. Absent any agreement to the contrary, the District shall pay to the Trustee from time to time compensation for all services rendered under this Indenture and also all expenses, charges, legal and consulting fees and other disbursements and those of its attorneys (including any allocated costs of internal counsel), agents and employees, incurred in and about the performance of its powers and duties under this Indenture. The Trustee has a first lien on the Tax Revenues, Net Revenues and all funds and accounts held by the Trustee hereunder to secure the payment to the Trustee of all fees, costs and expenses, including compensation to its experts, attorneys and counsel incurred in declaring such Event of Default and in exercising the rights and remedies set forth in Article VIII. Any such expenses incurred by the Trustee shall be deemed to constitute a substantial contribution to the trust estate which secures the Bonds. The District further covenants and agrees to indemnify and save the Trustee and its officers, directors, agents and employees, harmless against any loss, expense, including legal fees and expenses, and liabilities, whether or not litigated, suits, actions, judgments, which it may incur arising out of or in the exercise and performance of its powers and duties hereunder, including the costs and expenses of defending against any claim of liability and of enforcing any remedies hereunder and under any related documents, but excluding any and all losses, expenses and liabilities which are due to the negligence or willful misconduct of the Trustee, its officers, directors, agents or employees. The obligations of the District under this Section 6.06 shall survive resignation or removal -25- August 2, 2018 Regular Board Meeting Agenda Packet- Page 65 of 253 Page 38 of 183 of the Trustee under this Indenture and payment of the Bonds and discharge of this Indenture. SECTION 6.07. Accounting Records and Financial Statements. The Trustee shall at all times keep, or cause to be kept, proper books of record and account, prepared in accordance with corporate trust industry standards, in which complete and accurate entries shall be made of all transactions made by it relating to the proceeds of the Bonds and all funds and accounts established and held by the Trustee under this Indenture. Such books of record and account shall be available for inspection by the District at reasonable hours, during regular business hours, with reasonable prior notice and under reasonable circumstances. The Trustee shall furnish to the District, at least semiannually, an accounting (which may be in the form of its customary statements) of all transactions relating to the proceeds of the Bonds and all funds and accounts held by the Trustee under this Indenture. ARTICLE VII MODIFICATION AND AMENDMENT OF THIS INDENTURE SECTION 7.01. Amendments Permitted. (a) Amendment With Bond Owner Consent. This Indenture and the rights and obligations of the District and of the Owners of the Bonds may be modified or amended by the District and the Trustee upon Request of the District at any time by the execution of a Supplemental Indenture, but only with the written consent of the Owners of a majority in aggregate principal amount of the Bonds then Outstanding with respect to all Bonds then Outstanding, exclusive of Bonds disqualified as provided in Section 9.05. Any such Supplemental Indenture becomes effective upon the execution and delivery thereof by the parties thereto and upon consent of the requisite Bond Owners.

ARTICLE VIII EVENTS OF DEFAULT AND REMEDIES OF BOND OWNERS SECTION 8.01. Events of Default and Acceleration of Maturities. Each of the following events constitutes an Event of Default hereunder: (a) Failure to pay any installment of the principal of any Bonds when due, whether at maturity as therein expressed, by proceedings for acceleration, or otherwise. (b) Failure to pay any installment of interest on the Bonds when due. (c) Failure by the District to observe and perform any of the other covenants, agreements or conditions on its part contained in this Indenture or in the Bonds, if such failure has continued for a period of 60 days after written notice thereof, specifying such failure and requiring the same to be remedied, has been given to the District by the Trustee; provided, however, if in the reasonable opinion of the District the failure stated in the notice can be corrected, but not within such 60-day period, such failure shall not constitute an Event of Default if the District institutes corrective action within such 60-day period and thereafter diligently and in good faith cures the failure within 60 days after the written notice of default thereof. (d) The District commences a voluntary bankruptcy case under Title 11 of the United States Code or any substitute or successor statute.

Immediately upon becoming aware of the occurrence of an Event of Default, but in no event later than five Business Days following becoming aware of such occurrence, the Trustee shall give notice of such Event of Default to the District by telephone confirmed in writing. Such notice shall also state whether the principal of the Bonds has been declared to be or have immediately become due and payable. With respect to any Event of Default described in clauses (a) or (b) above the Trustee shall, and with respect to any Event of Default described in clause (c) above the Trustee in its sole discretion may, also give such notice to the Owners, which shall include the statement that interest on the Bonds shall cease to accrue from and after the date, if any, on which the Trustee declares the Bonds to become due and payable under the preceding paragraph (but only to the extent that principal and any accrued, but unpaid, interest on the Bonds is actually paid on such date). This provision, however, is subject to the condition that if, at any time after the principal of the Bonds has been so declared due and payable, and before any judgment or decree for the payment of the moneys due has been obtained or entered, the District shall deposit with the Trustee a sum sufficient to pay all principal on the Bonds matured prior to such declaration and all matured installments of interest(if any) upon all the Bonds, with interest on such overdue installments of principal and interest at an interest rate of 10% per annum, and the reasonable fees and expenses of the Trustee, including fees and expenses of its attorneys, and any and all other defaults known to the Trustee (other than in the payment of principal of and interest on the Bonds due and payable solely by reason of such declaration) has been made good or cured to the satisfaction of the Trustee or provision deemed by the Trustee to be adequate has been made therefor, then, and in every such case, the Owners of at least a majority in aggregate principal amount of the Bonds then Outstanding, by written notice to the District and to the Trustee, may, on behalf of the Owners of all of the Bonds, rescind and annul such declaration and its consequences. However, no such rescission and annulment shall extend to or shall affect any subsequent default, or shall impair or exhaust any right or power consequent thereon. SECTION 8.02.

(b) Second, to the payment of the whole amount then owing and unpaid upon the Bonds for interest and principal, with interest on such overdue amounts at the respective rates of interest borne by those Bonds, and in case such moneys shall be insufficient to pay in full the -29- August 2, 2018 Regular Board Meeting Agenda Packet- Page 69 of 253 Page 42 of 183 whole amount so owing and unpaid upon the Bonds, then to the payment of such interest, principal and interest on overdue amounts without preference or priority among such interest, principal and interest on overdue amounts ratably to the aggregate of such interest, principal and interest on overdue amounts. SECTION 8.03. Power of Trustee to Control Proceedings. If the Trustee, upon the happening of an Event of Default, takes any action, by judicial proceedings or otherwise, in the performance of its duties hereunder, whether upon its own discretion, upon the request of the Owners of a majority in aggregate principal amount of the Bonds then Outstanding, it has full power, in the exercise of its discretion for the best interests of the Owners of the Bonds, with respect to the continuance, discontinuance, withdrawal, compromise, settlement or other disposal of such action and the Trustee has been indemnified to its satisfaction. The Trustee may not, unless there no longer continues an Event of Default, discontinue, withdraw, compromise or settle, or otherwise dispose of any litigation pending at law or in equity, if at the time there has been filed with it a written request signed by the Owners of a majority in principal amount of the Outstanding Bonds hereunder opposing such discontinuance, withdrawal, compromise, settlement or other disposal of such litigation. SECTION 8.04. Limitation on Owners' Right to Sue. No Owner of any Bond has the right to institute any suit, action or proceeding at law or in equity, for any remedy under or upon this Indenture, unless: (a) said Owner has previously given to the Trustee written notice of the occurrence of an Event of Default; (b) the Owners of a majority in aggregate principal amount of all the Bonds then Outstanding have requested the Trustee in writing to exercise the powers hereinbefore granted or to institute such action, suit or proceeding in its own name; (c) said Owners have tendered to the Trustee indemnity reasonably acceptable to the Trustee against the costs, expenses and liabilities to be incurred in compliance with such request; and (d) the Trustee has failed to comply with such request for a period of 60 days after such written request has been received by, and said tender of indemnity has been made to, the Trustee. Such notification, request, tender of indemnity and refusal or omission are hereby declared, in every case, to be conditions precedent to the exercise by any Owner of any remedy hereunder; it being understood and intended that no one or more Owners has any right in any manner whatever by his or their action to enforce any right under this Indenture, except in the manner herein provided, and that all proceedings at law or in equity to enforce any provision of this Indenture shall be instituted, had and maintained in the manner herein provided and for the equal benefit of all Owners of the Outstanding Bonds.

SECTION 8.05. Non-waiver. Nothing in this Article VIII or in any other provision of this Indenture or in the Bonds, affects or impairs the obligation of the District, which is absolute and unconditional, to pay from the Net Revenues and other amounts pledged hereunder, the principal of and interest on the Bonds to the Bond Owners when due and payable as herein provided, or affects or impairs the right of action, which is also absolute and unconditional, of the Bond Owners to institute suit to enforce such payment by virtue of the contract embodied in the Bonds. A waiver of any default by any Owner shall not affect any subsequent default or impair any rights or remedies on the subsequent default. No delay or omission of any Owner to exercise any right or power accruing upon any default shall impair any such right or power or shall be construed to be a waiver of any such default or an acquiescence therein, and every power and remedy conferred upon the Owners by the Bond Law or by this Article VIII may be enforced and exercised from time to time and as often as shall be deemed expedient by the Owners. If a suit, action or proceeding to enforce any right or exercise any remedy is abandoned or determined adversely to the Owners, the District and the Owners will be restored to their former positions, rights and remedies as if such suit, action or proceeding had not been brought or taken. SECTION 8.06. Actions by Trustee as Attorney-in-Fact. Any suit, action or proceeding which any Owner has the right to bring to enforce any right or remedy hereunder may be brought by the Trustee for the equal benefit and protection of all Owners similarly situated and the Trustee is hereby appointed (and the successive respective Owners by taking and holding the Bonds shall be conclusively deemed so to have appointed it) the true and lawful attorney-in-fact of the respective Owners for the purpose of bringing any such suit, action or proceeding and to do and perform any and all acts and things for and on behalf of the respective Owners as a class or classes, as may be necessary or advisable in the opinion of the Trustee as such attorney-in-fact, subject to the provisions of Article VI.

SECTION 8.07. Remedies Not Exclusive. No remedy herein conferred upon or reserved to the Owners is intended to be exclusive of any other remedy.

Conditions to Obligations of the District. The performance by the District of its obligations is conditioned upon (i) the performance by the Underwriter of its obligations hereunder; and (ii) receipt by the District and the Underwriter of opinions and certificates being delivered at the Closing by persons and entities other than the District. 5. Establishment of Issue Price. A. The Underwriter agrees to assist the District in establishing the issue price of the 2018A Bonds and shall execute and deliver to the District at Closing an "issue price" or similar certificate, together with the supporting pricing wires or equivalent communications, substantially in the form attached hereto as Exhibit D, with such modifications as may be 14 August 2, 2018 Regular Board Meeting Agenda Packet- Page 114 of 253 Page 87 of 183 appropriate or necessary, in the reasonable judgment of the Underwriter, the District and Bond Counsel, to accurately reflect, as applicable, the sales price or prices or the initial offering price or prices to the public of the 2018A Bonds. B. Except as otherwise set forth in Exhibit A attached hereto, the District will treat the first price at which 10% of each maturity of the 2018A Bonds (the "10% test") is sold to the public as the issue price of that maturity. At or promptly after the execution of this Purchase Contract, the Underwriter shall report to the District the price or prices at which it has sold to the public each maturity of Bonds. If at that time the 10% test has not been satisfied as to any maturity of the 2018A Bonds, the Underwriter agrees to promptly report to the District the prices at which it sells the unsold Bonds of that maturity to the public. That reporting obligation shall continue, whether or not the Closing Date has occurred, until either (i) the Underwriter has sold all Bonds of that maturity or (ii) the 10% test has been satisfied as to the 2018A Bonds of that maturity, provided that, the Underwriter's reporting obligation after the Closing Date may be at reasonable periodic intervals or otherwise upon request of the District or Bond Counsel. For purposes of this Section, if Bonds mature on the same date but have different interest rates, each separate CUSIP number within that maturity will be treated as a separate maturity of the 2018A Bonds. C. The Underwriter confirms that it has offered the 2018A Bonds to the public on or before the date of this Purchase Contract at the offering price or prices (the "initial offering price"), or at the corresponding yield or yields, set forth in Exhibit A attached hereto, except as otherwise set forth therein. Exhibit A also sets forth, as of the date of this Purchase Contract, the maturities, if any, of the 2018A Bonds for which the Underwriter represents that (i) the 10% test has been satisfied (assuming orders are confirmed by the close of the business day immediately following the date of this Purchase Contract) and (ii) the 10% test has not been satisfied and for which the District and the Underwriter agree that the restrictions set forth in the next sentence shall apply, which will allow the District to treat the initial offering price to the public of each such maturity as of the sale date as the issue price of that maturity (the "hold-the- offering-price rule"). So long as the hold-the-offering-price rule remains applicable to any maturity of the 2018A Bonds, the Underwriter will neither offer nor sell unsold Bonds of that maturity to any person at a price that is higher than the initial offering price to the public during the period starting on the sale date and ending on the earlier of the following: a. the close of the fifth (5th) business day after the sale date; or b. the date on which the Underwriter has sold at least 10% of that maturity of the 2018A Bonds to the public at a price that is no higher than the initial offering price to the public. 15 August 2, 2018 Regular Board Meeting Agenda Packet- Page 115 of 253 Page 88 of 183 The Underwriter will advise the District promptly after the close of the fifth (5th) business day after the sale date whether it has sold 10% of that maturity of the 2018A Bonds to the public at a price that is no higher than the initial offering price to the public. D. The Underwriter confirms that: (i) any selling group agreement and any third-party distribution agreement relating to the initial sale of the 2018A Bonds to the public, together with the related pricing wires, contains or will contain language obligating each dealer who is a member of the selling group and each broker-dealer that is a party to such third-party distribution agreement, as applicable: (A)(i) to report the prices at which it sells to the public the unsold Bonds of each maturity allocated to it, whether or not the Closing Date has occurred, until either all Bonds of that maturity allocated to it have been sold or it is notified by the Underwriter that the 10% test has been satisfied as to the 2018A Bonds of that maturity, provided that, the reporting obligation after the Closing Date may be reasonable periodic intervals or otherwise upon request of the Underwriter and (ii) to comply with the hold-the-offering-price rule, if applicable, if and for so long as directed by the Underwriter, (B) to promptly notify the Underwriter of any sales of Bonds that, to its knowledge, are made to a purchaser who is a related party to an underwriter participating in the initial sale of the 2018A Bonds to the public (each such term being used as defined below), and (C) to acknowledge that, unless otherwise advised by the dealer or broker-dealer, the Underwriter shall assume that each order submitted by the dealer or broker-dealer is a sale to the public. (ii) any selling group agreement relating to the initial sale of the 2018A Bonds to the public, together with the related pricing wires, contains or will contain language obligating each dealer that is a party to a third-party distribution agreement to be employed in connection with the initial sale of the 2018A Bonds to the public to require each broker-dealer that is a party to such third-party distribution agreement to (A) report the prices at which it sells to the public the unsold Bonds of each maturity allocated to it, whether or not the Closing Date has occurred, until either all Bonds of that maturity allocated to it have been sold or it is notified by the Underwriter or the dealer that the 10% test has been satisfied as to the 2018A Bonds of that maturity, provided that, the reporting obligation after the Closing Date may be at reasonable periodic intervals or otherwise upon request of the Underwriter or the dealer, and (B) comply with the hold-the-offering-price rule, if applicable, if and for so long as directed by the Underwriter or the dealer and as set forth in the related pricing wires. E. The District acknowledges that, in making the representation set forth in this section, the Underwriter will rely on (i) in the event a selling group has been created in connection with the initial sale of the 2018A Bonds to the public, the agreement of each dealer who is a member of the selling group to comply with the requirements for establishing issue price of the 2018A Bonds, including, but not limited to, its agreement to comply with the hold- the-offering-price rule, if applicable to the 2018A Bonds, as set forth in a selling group 16 August 2, 2018 Regular Board Meeting Agenda Packet- Page 116 of 253 Page 89 of 183 agreement and the related pricing wires, and (ii) in the event that a third-party distribution agreement was employed in connection with the initial sale of the 2018A Bonds to the public, the agreement of each broker-dealer that is a party to such agreement to comply with the requirements for establishing issue price of the 2018A Bonds, including, but not limited to, its agreement to comply with the hold-the-offering-price rule, if applicable to the 2018A Bonds, as set forth in the third-party distribution agreement and the related pricing wires. The District further acknowledges that the Underwriter shall not be liable for the failure of any dealer who is a member of a selling group, or of any broker-dealer that is a party to a third-party distribution agreement, to comply with its corresponding agreement to comply with the requirements for establishing issue price of the 2018A Bonds, including, but not limited to, its agreement to comply with the hold-the-offering-price rule, if applicable to the 2018A Bonds. F. The Underwriter acknowledges that sales of any Bonds to any person that is a related party to an underwriter participating in the initial sale of the 2018A Bonds to the public (each such term being used as defined below) shall not constitute sales to the public for purposes of this section. Further, for purposes of this section: a. "public" means any person other than an underwriter or a related party; b. "underwriter" means (A) any person that agrees pursuant to a written contract with the District (or with the lead underwriter to form an underwriting syndicate) to participate in the initial sale of the 2018A Bonds to the public and (B) any person that agrees pursuant to a written contract directly or indirectly with a person described in clause (A) to participate in the initial sale of the 2018A Bonds to the public (including a member of a selling group or a party to a third-party distribution agreement participating in the initial sale of the 2018A Bonds to the public); C. a purchaser of any of the 2018A Bonds is a "related party" to an underwriter if the underwriter and the purchaser are subject, directly or indirectly, to (A) more than 50% common ownership of the voting power or the total value of their stock, if both entities are corporations (including direct ownership by one corporation of another), (B) more than 50% common ownership of their capital interests or profits interests, if both entities are partnerships (including direct ownership by one partnership of another), or (C) more than 50% common ownership of the value of the outstanding stock of the corporation or the capital interests or profit interests of the partnership, as applicable, if one entity is a corporation and the other entity is a partnership (including direct ownership of the applicable stock or interests by one entity of the other); and d. "sale date" means the date of execution of this Purchase Contract by all parties. 6. Expenses. 17 August 2, 2018 Regular Board Meeting Agenda Packet- Page 117 of 253 Page 90 of 183 (a) The Underwriter shall be under no obligation to pay, and the District shall pay or cause to be paid out of the proceeds of the Bonds, all expenses incident to the performance of the District's obligations hereunder, including but not limited to: the cost of photocopying and delivering the Bonds to the Underwriter; the cost of preparing, printing (and/or word processing and reproducing), distributing and delivering the District Documents, and the cost of printing, distributing and delivering the Preliminary Official Statement and the Official Statement; the cost of preparation of any "blue sky" or legal investment memoranda; and the fees and disbursements of Bond Counsel, any accountants, financial advisors or other engineers or experts or consultants the District has retained in connection with the Bonds and expenses (included in the expense component of the Underwriter's spread) incurred on behalf of the District's officers or employees which are incidental to implementing this Purchase Contract, including, but not limited to, meals, transportation, lodging, and entertainment of those officers or employees; provided, however, that (i) reimbursement for such expenses shall not exceed an ordinary and reasonable amount for such expenses and (ii) such expenses are not related to the entertainment of any person and not prohibited from being reimbursed from the proceeds of an offering of municipal securities under MSRB Rule G-20.

Flow of Funds under the Indenture The District previously established the"Wastewater System Funds,"which the District agrees in the Indenture to continue to hold and maintain for the purposes and uses set forth in the Indenture. The District agrees to deposit all of the Tax Revenues and Gross Revenues in the Wastewater System Funds immediately upon receipt. In addition to the transfers required to be made under any Parity Obligations, the District will withdraw amounts on deposit in the Wastewater System Funds and apply such amounts at the times and for the purposes, and in the priority, as follows: 10 August 2, 2018 Regular Board Meeting Agenda Packet- Page 140 of 253 Page 113 of 183 (i) Deposit and Application of Tax Revenues. On or before each Interest Payment Date, the District shall withdraw from the Wastewater System Funds and transfer to the Trustee for deposit in the Debt Service Fund an amount of Tax Revenues which,together with the balance then on deposit in the Debt Service Fund, is equal to the aggregate amount coming due and payable on the Bonds on the next succeeding Interest Payment Date. The District may not withdraw any Tax Revenues from the Wastewater System Funds in any Fiscal Year except for the purpose of making any payment to the Trustee as required by this subsection (i); provided, however, that at such time during any Fiscal Year as the amount of Tax Revenues on deposit in the Wastewater System Funds become equal to the aggregate amount of the debt service thereafter coming due and payable on the Bonds in such Bond Year, all remaining Tax Revenues received during such Fiscal Year will be released from the pledge and lien hereunder and may be used for any lawful purpose of the District. (ii) Deposit and Application of Net Revenues. If the amount of Tax Revenues transferred to the Trustee pursuant to the preceding clause (i) on or before each Interest Payment Date is less than the full amount required to be so transferred, the District shall withdraw Net Revenues from the Wastewater System Funds on such Interest Payment Date, and transfer to the Trustee for deposit in the Debt Service Fund, an amount equal to the amount of such insufficiency. (iii) No Preference or Priority. The District shall pay principal and interest on the Bonds and the principal of and interest on any Parity Obligations from the Tax Revenues and Net Revenues without preference or priority among the Bonds and Parity Obligations. If the amount of Tax Revenues and Net Revenues on deposit in the Wastewater System Funds is any time insufficient to enable the District to pay when due the principal and interest on the Bonds and the principal of and interest on the Parity Obligations, such payments shall be made on a pro rata basis. (iv) Other Uses of Wastewater System Funds. The District shall manage, conserve and apply moneys in the Wastewater System Funds in such a manner that all deposits required to be made under this Section and under any Parity Obligation Documents will be made at the times and in the amounts so required. Subject to the foregoing sentence, the District may at any time use and apply moneys in the Wastewater System Funds for any one or more of the following purposes: (A) the payment of Operation and Maintenance Costs, (B)the payment of any subordinate obligations or any unsecured obligations; (C)the acquisition and construction of extensions and improvements to the Wastewater System; (D)the payment of any amounts due and owing to the United States of America in accordance with this Indenture or any Parity Obligation Document; or(E) any other lawful purpose of the District. (v) Budget and Appropriation of Payments. The District shall adopt all necessary budgets and make all necessary appropriations of the principal and interest due on the Bonds from the Tax Revenues and Net Revenues. If any such payment requires the adoption by the District of any supplemental budget or appropriation, the District shall promptly adopt the same. The covenants on the part of the District contained in this paragraph constitute duties imposed by law and it shall be the duty of each and every public official of the District to take such actions and do such things as are required by law in the performance of the official duty 11 August 2, 2018 Regular Board Meeting Agenda Packet- Page 141 of 253 Page 114 of 183 of such officials to enable the District to carry out and perform the covenants and agreements in this paragraph. Rate Stabilization Fund The District may establish a fund to be held by it and administered in accordance with the Indenture, for the purpose of stabilizing the rates and charges imposed by the District with respect to the Wastewater System. From time to time the District may deposit amounts in the Rate Stabilization Fund, from any source of legally available funds, including but not limited to Tax Revenues and Net Revenues which are released from the pledge and lien which secures the Bonds and any Parity Obligations, as the District may determine. The District may, but is not required to, withdraw from any amounts on deposit in the Rate Stabilization Fund and deposit such amounts in the Wastewater System Funds in any Fiscal Year for the purpose of paying debt service on the Bonds coming due and payable in such Fiscal Year. Amounts so transferred from the Rate Stabilization Fund to the Wastewater System Funds shall constitute Gross Revenues for such Fiscal Year (except as otherwise provided in the Indenture), and shall be applied for the purposes of the Wastewater System Funds. Amounts on deposit in the Rate Stabilization Fund shall not be pledged to or otherwise secure the Bonds or any Parity Obligations. The District has the right at any time to withdraw any or all amounts on deposit in the Rate Stabilization Fund and apply such amounts for any lawful purposes of the District relating to the Wastewater System. No Reserve Fund The District is not funding a reserve fund for the Bonds. Accordingly, if Tax Revenues and Net Revenues are insufficient to make debt service payments on the Bonds and any Parity Obligations, Bondholders may not receive all amounts due to them. Rate Covenants The District agrees to the following rate covenants in the Indenture. Net Revenues Covenant. The District agrees to prescribe, revise and collect charges for the services and facilities of the Wastewater System which, after allowances for contingencies and error in the estimates, produce Gross Revenues (excluding capacity fees) sufficient in each Fiscal Year to provide Net Revenues which, together with the amount of Tax Revenues estimated by the District to be received during such Fiscal Year, are at least equal to 125% of the sum of the aggregate amount of the principal of and interest on the Bonds and any Parity Obligations coming due and payable during such Fiscal Year. Gross Revenues Covenant. The District further agrees to prescribe, revise and collect charges for the services and facilities of the Wastewater System which, after allowances for contingencies and error in the estimates, produce Gross Revenues (including, for clarity, capacity fees), which are sufficient in each Fiscal Year, together with the amount of Tax Revenues estimated by the District to be received during such Fiscal Year, to yield Gross Revenues at least equal to 100% of the sum of (i) the aggregate amount of the principal of and interest on the Bonds and any Parity Obligations coming due and payable during such Fiscal Year and (ii) estimated Operation and Maintenance Costs coming due and payable during such Fiscal Year. For the purpose of computing the amount of Gross Revenues or Net Revenues for any Fiscal Year for purposes of the foregoing covenants, the District shall be permitted to transfer amounts on deposit in the Rate Stabilization Fund for purposes of such computation (except that amounts that were transferred into the Rate Stabilization Fund from Gross Revenues and/or Tax Revenues received 12 August 2, 2018 Regular Board Meeting Agenda Packet- Page 142 of 253 Page 115 of 183 by the District in such Fiscal Year shall not be double-counted), and such transfers may be made until (but not after) 180 days after the end of such Fiscal Year. Parity Obligations No Current Parity or Senior Obligations. Assuming the refunding in full of the 2009 Certificates, there will be no bonds, notes or other obligations of the District payable from the Tax Revenues or the Net Revenues on a senior or parity basis with the Bonds. Future Parity Obligations. The District may issue or incur other bonds, notes, loans, advances or indebtedness payable from Tax Revenues and/or the Net Revenues on a parity with the Bonds to provide financing for the Wastewater System in such principal amount as the District may determine. The District may issue or incur any Parity Obligations subject to the following specific conditions which are hereby made conditions precedent to the issuance and delivery of any Parity Obligations: (a) No Event of Default has occurred and is continuing. (b) The Tax Revenues and the Net Revenues (excluding capacity fees), calculated in accordance with sound accounting principles, as shown by the books of the District for the latest Fiscal Year or as shown by the books of the District for any other 12- month period selected by the District ending not more than 90 days prior to the date of issuance of such Parity Obligation, in either case verified by a certificate or opinion of an Independent Accountant employed by the District, plus (at the option of the District) the Additional Revenues, are at least equal to 125% of the amount of Maximum Annual Debt Service with respect to the Bonds and all Parity Obligations then outstanding (including the Parity Obligation then proposed to be issued). (c) The trustee or fiscal agent for such Parity Obligation must be the same entity performing the functions of Trustee under the Indenture. State Loans. The District may borrow money from the State and incur State Loans to finance improvements to the Wastewater System. A State Loan may be treated as a Parity Obligation for purposes of this Indenture without compliance with clause (c) above, so long as the District complies with the foregoing clauses (a) and (b). Definition of Additional Revenues. "Additional Revenues" is defined in the Indenture as any or all of the following amounts: (i) An allowance for Net Revenues from any additions or improvements to or extensions of the Wastewater System to be financed from the proceeds of such Parity Obligations or from any other source but in any case which, during all or any part of the most recent completed Fiscal Year for which audited financial statements are available or for any more recent 12 month period selected by the District, were not in service, all in an amount equal to the estimated additional average annual Net Revenues to be derived from such additions, improvements and extensions during the first full Fiscal Year in which each addition, improvement or extension is respectively to be in operation, all as shown by a certificate of a District Representative. (ii) An allowance for Net Revenues arising from any increase in the charges made for service from the Wastewater System which has become effective prior to the incurring of such Parity Obligations but which, during all or any part of such Fiscal Year or such 12 month period, was not in effect, in an amount equal to the total amount by which the Net Revenues would have been increased if such increase 13 August 2, 2018 Regular Board Meeting Agenda Packet- Page 143 of 253 Page 116 of 183 in charges had been in effect during the whole of such Fiscal Year or such 12 month period, all as shown by a certificate of a District Representative. Insurance; Eminent Domain Insurance. The District will at all times maintain with responsible insurers all such insurance on the Wastewater System as is customarily maintained with respect to works and properties of like character against accident to, loss of or damage to the Wastewater System. The District shall also maintain, with responsible insurers, worker's compensation insurance and insurance against public liability and property damage to the extent reasonably necessary to protect the District, the Trustee and the Owners of the Bonds. The Net Proceeds collected by the District from insurance against accident to or destruction of any portion of the Wastewater System shall be used to repair or rebuild such damaged or destroyed portion of the Wastewater System, and to the extent not so applied, shall be applied on a pro rata basis to redeem the Bonds and any Parity Obligations in accordance with this Indenture and the related Parity Obligation Documents. Eminent Domain. Except as provided in the Indenture, the District covenants that the Wastewater System will not be encumbered, sold, leased, pledged, any charge placed thereon, or otherwise disposed of, as a whole or substantially as a whole, if such encumbrance, sale, lease, pledge, charge or other disposition would materially impair the ability of the District to pay the principal of or interest on the Bonds or any Parity Obligations, or would materially adversely affect its ability to comply with the terms of the Indenture or any Parity Obligation Documents. The District may not enter into any agreement which impairs the operation of the Wastewater System or any part of it necessary to secure adequate Tax Revenues and Net Revenues to pay the Bonds and any Parity Obligations, or which otherwise would impair the rights of the Bond Owners with respect to the Tax Revenues and Net Revenues. The Net Proceeds received as awards as a result of the taking of all or any part of the Wastewater System by the lawful exercise of eminent domain, if and to the extent that such right can be exercised against such property of the District, shall either (a) be used for the acquisition or construction of improvements and extension of the Wastewater System, or(b) be applied on a pro rata basis to redeem the Bonds and any Parity Obligations in accordance with the Indenture and the related Parity Obligation Documents. See "APPENDIX A—Summary of the Indenture." Limited Obligation The District's obligation to pay the Bonds and any other amounts coming due and payable under the Indenture are a special obligation of the District limited solely to the Tax Revenues and the Net Revenues. Under no circumstances is the District required to advance moneys derived from any source of income other than the Tax Revenues and Net Revenues and other sources specifically identified in the Indenture for the payment of the Bonds and such other amounts, nor are any other funds or property of the District liable for the payment of the Bonds and any other amounts coming due and payable under the Indenture. Provisions Relating to Collection of Tax Revenues Definition. The Indenture defines "Tax Revenues" as all ad valorem taxes allocable to the Wastewater System which are levied upon taxable property in the District by the Board of Supervisors of Contra Costa County, and which are allocated to the District under the provisions of Chapter 6 of Part 0.5 of Division 1 of the Revenue and Taxation Code of the State of California, including all payments, subventions and reimbursements, if any, to the District specifically attributable to taxes lost by reason of tax exemptions and tax rate limitations; but excluding any taxes levied for the sole purpose 14 August 2, 2018 Regular Board Meeting Agenda Packet- Page 144 of 253 Page 117 of 183 of providing for payment of principal and interest on any voter-approved indebtedness incurred by the District, which taxes would not otherwise be subject to levy but for the issuance of such indebtedness. See "RISK FACTORS — Property Taxes" for a discussion of certain factors that could impact the availability of Tax Revenues. Property Tax Limitations; Article XIIIA of the California Constitution. California voters, on June 6, 1978, approved an amendment(commonly known as both Proposition 13 and the Jarvis-Gann Initiative) to the California Constitution. This amendment, which added Article XIIIA to the California Constitution, among other things, affects the valuation of real property for the purpose of taxation in that it defines the full cash value of property to mean "the county assessor's valuation of real property as shown on the 1975/76 tax bill under full cash value, or thereafter, the appraised value of real property when purchased, newly constructed, or a change in ownership has occurred after the 1975 assessment." The full cash value may be adjusted annually to reflect inflation at a rate not to exceed 2% per year, or any reduction in the consumer price index or comparable local data, or any reduction in the event of declining property value caused by damage, destruction or other factors. The amendment further limits the amount of any ad valorem tax on real property to 1% of the full cash value except that additional taxes may be levied to pay debt service on indebtedness approved by the voters prior to July 1, 1978. In addition, an amendment to Article XIIIA was adopted in June 1986 by initiative which exempts any bonded indebtedness approved by two-thirds of the votes cast by voters for the acquisition or improvement of real property from the 1% limitation. In the general election held November 4, 1986, voters of the State of California approved two measures, Propositions 58 and 60, which further amend Article XIIIA. Proposition 58 amends Article XIIIA to provide that the terms "purchased" and "change of ownership," for purposes of determining full cash value of property under Article XIIIA, do not include the purchase or transfer of (1) real property between spouses and (2) the principal residence and the first $1,000,000 of other property between parents and children. Proposition 60 amends Article XIIIA to permit the Legislature to allow persons over age 55 who sell their residence to buy or build another of equal or lesser value within two years in the same county, to transfer the old residence's assessed value to the new residence. Pursuant to Proposition 60, the Legislature has enacted legislation permitting counties to implement the provisions of Proposition 60. Implementing Legislation. Legislation enacted by the California Legislature to implement Article XIIIA (Statutes of 1978, Chapter 292, as amended) provides that, notwithstanding any other law, local agencies may not levy any property tax, except to pay debt service on indebtedness approved by the voters prior to July 1, 1978, and that each county will levy the maximum tax permitted by Article XIIIA of$4.00 per$100 assessed valuation (based on the traditional practice in California of using 25% of full cash value as the assessed value for tax purposes). The legislation further provided that, for fiscal year 1978-79, the tax levied by each county was to be appropriated among all taxing agencies within the county in proportion to their average share of taxes levied in certain previous years. The apportionment of property taxes in fiscal years after fiscal year 1978-79 has been revised pursuant to Statutes of 1979, Chapter 282 which provides relief funds from State moneys beginning in fiscal year 1978-79 and is designed to provide a permanent system for sharing State taxes and budget surplus funds with local agencies. Under Chapter 282, cities and counties receive about one- third more of the remaining property tax revenues collected under Proposition 13 instead of direct State aid. School districts receive a correspondingly reduced amount of property taxes, but receive compensation directly from the State and are given additional relief. Chapter 282 does not affect the derivation of the base levy ($4.00 per$100 assessed valuation) and the bonded debt tax rate. Effective as of fiscal year 1981-82, assessors in California no longer record property values in the tax rolls at the assessed value of 25% of market values. All taxable property is shown at full market value (subject to a 2% annual limit in growth so long as property is not sold). In conformity with this 15 August 2, 2018 Regular Board Meeting Agenda Packet- Page 145 of 253 Page 118 of 183 change in procedure, all taxable property value included in this Official Statement is shown at 100% of market value and all general tax rates reflect the $1 per $100 of taxable value. Tax rates for bond service and pension liability are also applied to 100% of market value. Future assessed valuation growth allowed under Article XIIIA (new construction, change of ownership, annual inflationary value growth of up to 2%)will be allocated on the basis of"situs" among the jurisdictions that serve the tax rate area within which the growth occurs except for certain utility property assessed by the State Board of Equalization ("Unitary Property") which is allocated by a different method as described under"—Unitary Property" below. Classifications of Property. In California, property which is subject to ad valorem taxes is classified as "secured" or "unsecured." Secured and unsecured properties are entered on separate parts of the assessment roll maintained by the county assessor. The secured classification includes property on which any property tax levied by the County becomes a lien on that property sufficient, in the opinion of the county assessor, to secure payment of the taxes. Every tax which becomes a lien on secured property has priority over all other liens on the secured property, regardless of the time of the creation of other liens. A tax levied on unsecured property does not become a lien against the taxes on unsecured property, but may become a lien on certain other property owned by the taxpayer. Collections. The method of collecting delinquent taxes is substantially different for the two classifications of property. The taxing authority has four ways of collecting unsecured property taxes in the absence of timely payment by the taxpayer: (1) a civil action against the taxpayer; (2) filing a certificate in the office of the county clerk specifying certain facts an order to obtain a judgment lien on certain property of the taxpayer; (3)filing a certificate of delinquency for record in the county recorder's office, in order to obtain a lien on certain property of the taxpayer; and (4) seizure and sale of the personal property, improvements or possessory interests belonging or assessed to the assessee. The exclusive means of enforcing the payment of delinquent taxes with respect to property on the secured roll is the sale of property securing the taxes to the State for the amount of taxes which are delinquent. A 10% penalty also applies to delinquent taxes on property on the unsecured roll, and further, an additional penalty of 1 1/2% per month accrues with respect to such taxes beginning the first day of the third month following the delinquency date. The valuation of property is determined as of January 1 each year and equal installments of taxes levied upon secured property become delinquent on the following December 10 and April 10. Taxes on unsecured property are due August 1 and become delinquent August 31. Supplemental Assessments. A bill enacted in 1983, SB 813 (Statutes of 1983, Chapter 498) provides for the supplemental assessment and taxation of property as of the occurrence of a change in ownership or completion of new construction. Previously, statutes enabled the assessment of such changes only as of the next tax lien date following the change and thus delayed the realization of increased property taxes from the new assessments for up to 14 months. As enacted, Chapter 498 provided increased revenue to redevelopment agencies to the extent that supplemental assessments as a result of new construction or changes of ownership occur within the boundaries of redevelopment projects subsequent to the tax lien date. To the extent such supplemental assessments occur within the Project Area, Tax Revenue may increase. Property Tax Administration Costs. In 1990,the Legislature enacted SB 2557(Chapter 466, Statutes of 1990) which allows counties to charge for the cost of assessing, collecting and allocating property tax revenues to local government jurisdictions on a prorated basis. Unitary Property. Commencing in fiscal year 1988-89,the Revenue and Taxation Code of the State of California changed the method of allocating property tax revenues derived from State assessed utility properties. It provides for the distribution of State assessed values to tax rate areas 16 August 2, 2018 Regular Board Meeting Agenda Packet- Page 146 of 253 Page 119 of 183 by a county-wide mathematical formula rather than assignment of State assessed value according to the location of those values in individual tax rate areas. Commencing with fiscal year 1988-89, each county has established one county-wide tax rate area. The assessed value of all unitary property in the county has been assigned to this tax rate area and one tax rate is levied against all such property ("Unitary Revenues"). The property tax revenue derived from the assessed value assigned to the county-wide tax rate area shall be allocated as follows: (1) each jurisdiction will be allocated up to 2% of the increase in Unitary Revenues on a pro rata basis county-wide; and (2) any decrease in Unitary Revenues or increases less than 2%, or any increase in Unitary Revenues above 2% will be allocated among jurisdictions in the same proportion of each jurisdiction's Unitary Revenues received in the prior year to the total Unitary Revenues county-wide. However, legislation adopted in 2006 (SB 1317, Chapter 872) and taking effect with fiscal year 2007-08 required counties to transfer certain railroad properties into a countywide tax rate area from their existing tax rate area. Taxes on these properties are now distributed in a manner similar to other unitary properties, except that redevelopment agencies no longer share in the distribution. Assessment Appeals. An assessee of locally assessed or State-assessed property may contest the taxable value enrolled by the county assessor or by the State Board of Equalization ("SBE"), respectively. The assessee of SBE-assessed property or locally-assessed personal property, the valuation of which is subject to annual reappraisal, actually contests the determination of the full cash value of property when filing an assessment appeal. Because of the limitations to the determination of the full cash value of locally assessed real property by Article XIIIA, an assessee of locally assessed real property generally contests the original determination of the base assessment value of the parcel, i.e. the value assigned after a change of ownership or completion of new construction. In addition, the assessee of locally assessed real property may contest the current assessment value (the base assessment value plus the compounded annual inflation factor) when specified conditions have caused the full cash value to drop below the current assessment value. At the time of reassessment, after a change of ownership or completion of new construction, the assessee may appeal the base assessment value of the property. Under an appeal of a base assessment value, the assessee appeals the actual underlying market value of the sale transaction or the recently completed improvement.A base assessment appeal has significant future revenue impact because a reduced base year assessment will then reduce the compounded value of the property prospectively. Except for the 2% inflation factor allowable under Article XIIIA, the value of the property cannot be increased until a change of ownership occurs or additional improvements are added. Under Section 51(b) of the Revenue and Taxation Code, the assessor may place a value on the tax roll lower than the compounded base assessment value if the full cash value of real property has been reduced by damage, destruction, depreciation, obsolescence, removal of property or other factors causing a decline in the value. Reductions in value under Section 51(b), commonly referred to as Proposition 8 reductions, can be achieved either by formal appeal or administratively by assessor staff appraising the property. A reduced full cash value placed on the tax roll does not change the base assessment value. The future impact of a parcel subject to a Proposition 8 appeal is dependent upon a change in the conditions which caused the drop in value. In fiscal years following a successful Proposition 8 appeal, the assessor may determine that the value of the property has increased as a result of corrective actions or improved market conditions and enroll a value on the tax roll up to the parcel's compounded base assessment value. Additionally, successful appeals regarding property on the unsecured rolls does not necessarily affect the valuation of such property in any succeeding fiscal year. Utility companies and railroads may contest the taxable value of utility property to the SBE. Generally, the impact of utility appeals is on the State-wide value of a utility determined by SBE. 17 August 2, 2018 Regular Board Meeting Agenda Packet- Page 147 of 253 Page 120 of 183 The actual valuation impact to the District from successful assessment appeals will occur on the assessment roll prepared after the actual valuation reduction. THE DISTRICT General The District, which was established in 1946 under the Sanitary District Act of 1923, builds, operates and maintains the facilities required to collect and process wastewater for the approximately 348,000 residents of Danville, Lafayette, Martinez, Moraga, Orinda, Pleasant Hill, San Ramon, and Walnut Creek, encompassing a service area of 145 square miles. The District also treats wastewater for 140,000 residents (as of 2018) of the Concord/Clayton area under a contract with the City of Concord, referred to herein as the Concord Agreement. The District also provides household hazardous waste disposal services for the localities noted above, and for an additional 9 square mile area of portions of Martinez and San Ramon served by other wastewater utility providers. The District is located approximately 30 miles east of San Francisco, California. During 2018,the District was inducted as a member of Leading Utilities of the World, a network of the world's most forward-thinking water and wastewater utilities. The District's wastewater facility has also won the National Association of Clean Water Agencies (NACWA) 20th Platinum Award, continuing a distinguished record of excellence. NACWA Platinum Awards recognize 100% compliance with permits over a consecutive five-year period. Platinum Awards are be given to facilities with a consistent record of full compliance for a consecutive five year period District Facilities General. There are approximately 1,540 miles of sewer pipeline, ranging in size from 6 inches to 120 inches in diameter, and 18 sewage pumping stations in the District's sewerage system. The District's treatment plant in Martinez (the "Treatment Plant") treats an average dry weather daily flow (ADWF) of 35 million gallons of wastewater each day. In addition: • The District incinerates approximately 200 wet tons of sludge each day, reducing the sludge to approximately 10-14 tons of sterile ash. • The District operates a cogeneration facility that uses a combination of methane from a landfill and natural gas to produce electricity and steam for the plant. On average, approximately 3,200 kilowatts of power - more than 90% of the plant's daily power needs- is produced. • The District produces approximately 600 million gallons of recycled water each year for plant operations, industrial uses, and landscape irrigation. In addition to its wastewater responsibility, the District also operates a Household Hazardous Waste Collection Facility(the"HHW Collection Facility") in Contra Costa County. The HHW Collection Facility collects approximately 2 million pounds of household hazardous waste each year. The HHW Collection Facility is located adjacent to the District's wastewater treatment plant. Treatment Plant. The Treatment Plant treats approximately 35 million gallons (ADWF) of wastewater per day("MGD"). Located in Martinez, the Treatment Plant has a treatment capacity of 54 MGD and 250 MGD of wet weather flow. The Treatment Plant processed an average daily flow of 44 MGD in 2017 and a peak hourly flow of 181 MGD during 2017. The Plant Operations Building houses the Control Center, a state-of-the-art computerized system that monitors and controls every phase of the treatment process. The Treatment Plant is staffed 24 hours a day, 365 days a year. Wastewater moves through the District's 1,540 miles of sewer lines, finally arriving at the Treatment Plant's headworks to begin treatment. Most of the wastewater is treated to a secondary 18 August 2, 2018 Regular Board Meeting Agenda Packet- Page 148 of 253 Page 121 of 183 level, disinfected by ultraviolet light, and then discharged into Suisun Bay. Approximately 600 million gallons per year are treated to a tertiary level through additional filtration and disinfection before being distributed as Recycled Water for landscape irrigation, industrial processes, and plant operations. Recycled Water. Part of the Treatment Plant's operation, the Recycled Water Program produces approximately up to 600 million gallons of recycled water for irrigation, landscaping and industrial use. CCCSD provides landscape irrigation water that meets all the requirements of the State Department of Health Services and the California Regional Water Quality Control Board for unrestricted landscape irrigation. Approved uses include irrigation at schools, parks, playgrounds, median strips and playing fields, as well as dust control and industrial uses. Recycled water is distributed directly to users via a pressure distribution system that consists of purple pipelines, pumping stations, and meter box assemblies (purple pipes are used to distinguish them from drinking water lines). The recycled water distribution system is completely separate from the drinking water distribution system. A comprehensive evaluation and physical test of each customer's water system is conducted to verify that it is separate from any drinking water system. This inspection is required by the Department of Health Services prior to any customer beginning service off the recycled water system, and ensures that no cross-connections occur between the customer's drinking water system and the District's recycled water system. Laboratory. A state-of-the-art facility performs almost 40,000 chemical and biological tests each year. HHW Collection Facility. The HHW Collection Facility collects more than two million pounds of hazardous waste each year. The HHW Collection Facility is located adjacent to the Treatment Plant.

The 161 non- supervisory employees of the District are represented by Public Employees Union, Local #1, Concord ("Local#11"). The 95 supervisors, middle managers, and confidential employees are represented by the Management Support and Confidential Group ("MSCG"). The current Memoranda of Understanding with Local #1 and with MSCG each expired on December 17, 2017. Negotiations with the bargaining units have been ongoing since mid-2017. In June 2018, notices of impasse were provided by the District to Local #1 and MSCG, and mediation commenced with a State of California mediator to facilitate continued discussion between the bargaining units and the District. In addition to the current MOU 20 August 2, 2018 Regular Board Meeting Agenda Packet- Page 150 of 253 Page 123 of 183 period, negotiations for the last five-year contract also extended beyond the expiration date. The District has not experienced any interruptions in operations because of employer/employee disputes. Pension Plan Substantially, all District full-time employees are required to participate in the Contra Costa County Employees' Retirement Association ("CCCERA"), a cost-sharing multiple-employer public employee deferred benefit retirement plan (the "Plan"), governed by the County Employee's Retirement Law of 1937 ("CERU), as amended, and the California Public Employees' Pension Reform Act of 2013 ("PEPRA"). The latest available actuarial and financial information for the Plan is for the year ended December 31, 2016. The Contra Costa Employees' Retirement Association issues a publicly available financial report that includes financial statements and supplemental information of the Plan. The Plan provides for retirement, disability, and death and survivor benefits. Annual cost of living (COL)adjustments to retirement allowances can be granted by the Retirement Board as provided by State statutes. Service retirements are based on age, length of service and final average salary. Subject to vested status, employees can withdraw contributions plus interest credited, or leave them as a deferred retirement when they terminate, or transfer to a reciprocal retirement system. Contributions to the Plan are made by both the members (active employees) and the District based upon a percentage of each member's pensionable compensation. Employee membership in CCCERA is divided into two tiers: Legacy members (membership or reciprocal membership prior to January 1, 2013) and PEPRA members (membership on or after January 1, 2013 and reciprocity not eligible for Legacy membership). Contribution rates are determined by annual actuarial valuations and approved by the CCCERA Board to fund the Normal Cost for a given years' service and any unfunded liability that has accrued. The cost-sharing split of Normal cost for Legacy members is stipulated in the CERL and varies based on an employee's entry age into the system. PEPRA members are required by PEPRA to pay at least 50% of the Normal Cost. All contributions towards the unfunded liability are borne by the District. The District Board can negotiate additional retirement expense cost-sharing pursuant to the terms of a collective bargaining agreement/MOU with employee bargaining units. The Plans' provisions and benefits in effect as of July 1, 2017, are summarized as follows: Tier Legagy PEPRA Membership Date Before 1/1/13, Including On or after Reciprocity 1/1/13 Membership Count 220 54 Employee Rates 11.85% (Average) 11.70% District Rates 53.39% 48.01% Benefit Formula 2%@55 2%@62 Vesting 5 Years, but Benefit 5 Years Starts after 10 Years Retirement Age 50 52 Benefit Cap 100% of Salary No Cap Pensionable Income Most Non-Overtime Pay Base Pay Only Annual Income Cap 2017: $2701000 2017: $1421530 21 August 2, 2018 Regular Board Meeting Agenda Packet- Page 151 of 253 Page 124 of 183 Contributions - The contribution requirement and payment from the District for the plan year ended June 30, 20171 2016 and 2015 was as follows: 2017 2016 2015 Covered payroll for fiscal years ended June 30, $ 3215011073 $ 3015521659 $ 2719301233 Employer contributions to pension 1810431391 2217521611 2414511234 Employee contributions to pension 516081003 511961358 518601025 Total Contributions $ 2316511394 $ 2719481969 $ 3013111259 Source:Central Contra Costa Sanitary District. Unfunded Liability - The unfunded actuarial accrued liabilities with CCCERA for the past five years were as follows: December 31, 2012 $14215231585 December 31, 2013 $12017921362 December 31, 2014 $10019551188 December 31, 2015 $8811821228 December 31, 2016 $8115501100 The amounts set forth in this discussion of the District's Retirement costs and figures, including, for example, actuarial accrued liabilities and funded ratios, are based upon numerous demographic and economic assumptions, including investment return rates, inflation rates, salary increase rates, cost of living adjustments, postemployment mortality, active member mortality, and rates of retirement. Prospective purchasers of the District's bonds are cautioned to review and carefully assess the reasonableness of the assumptions set forth in the documents that are cited as the sources for such information. In addition, prospective purchasers of the District's bonds are cautioned that such sources and the underlying assumptions are made as of their respective dates, and are subject to change. Prospective purchasers of the District's bonds should also be aware that some of the information presented in this discussion of the Retirement System contains forward- looking statements and the actual results of the CCCERA retirement plans may differ materially from the information presented herein. In 2017, the District established a Pension Prefunding Trust Fund to accumulate assets that can be used to pay CCCERA pension funding obligations. A third party, PARS, administers this Trust, and Highmark Capital Management serves as investment advisor. Per PARS, the market value of trust assets as of March 30, 2018, including trust contributions and interest was $4,374,815. See notes to the financial statements for additional information about the Pension Plan. Litigation involving CCCERA. The District is a party in two cases in which labor organizations have challenged the implementation of recent pension reform legislation authored by Governor Brown alleging that the "anti-spiking" reform provisions interfere with vested rights of current members of the CCCERA, of which the District is a member agency. The primary case arising in the County was consolidated with several similar cases from other counties. The consolidated cases are now entitled Alameda County Deputy Sheriff's Association v. Alameda County Employees Retirement Ass. and BD. of Alameda County Employees Retirement Assn. and the matter is now before the California Supreme Court (Case No. S247095). The enactment and implementation of this new legislation eliminated several mechanisms whereby retirees could significantly enhance pension benefits through adding the value of unused accumulated vacation and sick leave buy backs at or near the time of retirement. The trial court decision generally sustained implementation 22 August 2, 2018 Regular Board Meeting Agenda Packet- Page 152 of 253 Page 125 of 183 of the legislative reform provisions, which had the effect of reducing the District's normal retirement and URAL costs by several millions of dollars per year. The Appellate Court reversed the trial court ruling and the appeal from that decision is before the Supreme Court. If the Supreme Court upholds implementation of the legislative pension reforms, the pension costs of the District will remain much the same as they have been over the last several fiscal years. If the Supreme Court deems that certain of the reform provisions violate the prior vested rights of certain employees, then both the District's normal and URAL pension costs will increase potentially by an amount up to approximately 6% of the District's total annual salary cost for a number of years into the future. Post-Employment Health Care Benefits The District provides certain health care and, depending on Tier, certain other benefits for retired employees and beneficiaries. These other post-employment benefits ("OPEB Benefits") are specified in negotiated employment agreements, commonly referred to as Memorandums of Understanding, which cover substantially all employees who reach normal retirement age while working for the District. The OPEB Benefits are provided through a defined benefit post-employment healthcare plan (DPHP). The DPHP is part of the Public Agency portion of the Public Agency Retirement System (PARS), an agent multiple-employer plan administered by PARS,which acts as a common investment and administrative agent for participating public employees within the State of California. A menu of benefit provisions as well as other requirements is established by the State statute with the Public Employees' Retirement Law. DPHP selects optional benefit provisions from the benefit menu by contract with PARS and adopts those benefits through District resolution. PARS issues a separate Comprehensive Annual Financial Report. The level of OPEB Benefits offered to employees vary by hire date. Presently, three primary levels of OPEB Benefit tiers exist,with the latest Tier effective for employees hired after June 30, 2009. Benefits are also provided to spouses of retirees, and for two of the three tiers, other dependents. In 2009, the District established an OPEB Trust Fund to accumulate assets and pay OPEB benefits related to eligible retirees. PARS administers this Trust, and Highmark Capital Management serves as investment advisor. Per PARS, trust assets as of June 30, 2017 and 2016, including trust contributions and interest, total $52,328,367 and $42,703,154, respectively In April 2004, the Governmental Accounting Standards Board ("GASB") issued Statement No. 43, "Financial Reporting for Postemployment Benefit Plans Other Than Pension Plans."Statement No. 43 establishes uniform financial reporting standards for postemployment healthcare and other non- pension benefits ("OPEB") plans. The approach followed in Statement No. 43 is generally consistent with the approach adopted for defined benefit pension plans with modifications to reflect differences between pension plans and OPEB plans. Statement No. 43 became effective for the District for the fiscal year ending June 30, 2009. In addition, in June 2004, GASB issued Statement No.45, Accounting and Financial Reporting by Employers for Postemployment Benefits Other Than Pensions, which addresses how state and local governments should account for and report their costs and obligations related to OPEB. Statement No. 45 generally requires that employers account for and report the annual cost of OPEB and the outstanding obligations and commitments related to OPEB in essentially the same manner as they currently do for pensions. Statement No. 45's provisions may be applied prospectively and do not require governments to fund their OPEB plans. An employer may establish its OPEB liability at zero as of the beginning of the initial year of implementation; however, the unfunded actuarial accrued liability is required to be amortized over future periods. Statement No. 45 also establishes disclosure requirements for information about the plans in which an employer participates, the funding policy followed, the actuarial valuation process and assumptions, and, for certain employers, the extent to 23 August 2, 2018 Regular Board Meeting Agenda Packet- Page 153 of 253 Page 126 of 183 which the plan has been funded over time. Statement No. 45 became effective for the District's fiscal year ending June 30, 2009. Unfunded Liability - The unfunded actuarial accrued liabilities attributed to OPEB for the last five fiscal years were as follows: FY 2013-14 $7517691000 FY 2014-15 $7012091000 FY2015-16 $6719611000 FY 2016-17 $5518471000 FY 2017-18 $5410301000 See Note 10 to the District's fiscal year 2016-17 audited financial statements appended to this Official Statement as Appendix C for further information about the cost and funding status of the District's OPEB plan. Investment Policy The investment policies and practices of the District are established by ordinance of the District's Board of Directors. The investment policy is reviewed annually by the Board of Directors. The investment policy was last updated in September 2017. The investment policy specifies allowable investments for the District's working and reserve funds ("general investments"), as well as providing separate guidelines for fiduciary Trust fund investments (OPEB Trust and Pension Prefunding Trust) and bond related investments(which are subject to bond related documents). Bond related investments are limited to instruments specified as Permitted Investments. See "APPENDIX A—Summary of Indenture"for the Permitted Investments definition for the Bonds. The maximum maturity for general investments of the District is one year. Prior approval of the Board of Directors must be obtained to acquire investments with maturities beyond five years. The District uses the services of the Treasurer's Office of the County of Contra Costa to transact the District's investment decisions. The County Treasurer's Office executes the District's investments through such brokers, dealers, and financial institutions as are approved by the County Treasurer, and through the State Treasurer's Office for investments in the Local Agency Investment Fund. The Finance Manager submits a monthly investment report to the Board of Directors. According to the monthly investment report for the month ended April 30, 2018, the District had invested funds in its Running Expense Fund (from which the District pays for ongoing operations)and Sewer Construction Fund as set forth in the table below. The District had, as of April 30, 2018, sufficient funds in the Running Expense Fund and Sewer Construction Fund to pay for six months of cash flow needs. 24 August 2, 2018 Regular Board Meeting Agenda Packet- Page 154 of 253 Page 127 of 183 TABLE 1 CENTRAL CONTRA COSTA SANITARY DISTRICT Investment Portfolio Summary(l) (as of April 30, 2018) Investment Type Market Value Par Value Maturity Date Annual Yield LAIF $5813551973 $5815001000 -- --(2) Comm Paper 214851688 215001000 7/25/2018 2.300% Comm Paper 214851465 215001000 7/27/2018 2.313% FHLB 19,962,400 20,000,000 6/8/2018 1.420% FHLB 319841040 410001000 7/18/2018 1.817% FHLB 4,978,300 5,000,000 7/25/2018 1.877% Total $9212511866 $9215001000 (1)Does not include the District's Self-Insurance Fund,which is invested in the State's Local Agency Investment Fund(LAIF).

In 1974 the District entered into a contract with the City of Concord to provide wastewater treatment and disposal services for both the City of Concord and the City of Clayton. The contract, which has been amended five times (1976, 1982, 1985, 1987, and 2002), sets forth the terms and conditions under which the District is to perform services and the City is to reimburse the District for its capital and operations and maintenance costs. This agreement, as amended, is the "Concord Agreement" as defined in the Indenture. The original contract was approved on September 10, 1974 and continued in effect until 1999, at which time the contract was renewed for another 25 years. The contract renews itself automatically every 25 years on the same terms unless one party of the contract gives a 5 year notice to the other party prior to the expiration of any 25 year term, of its intention to terminate. The District has not been notified and District staff is not aware of any intention to terminate the contract. Concord/Clayton's sewer system is connected to the District's interceptor sewers at three locations. Wastewater flow meters record the volume discharged at each location. Concord pays the District for its share of the District's operation and maintenance costs and its share of capital costs for commonly used facilities based on the total volumes and strengths of sewage generated within Concord's and the District's service areas. The flow proportion for Fiscal Year 2017-18 from Concord/Clayton is approximately 34%. The District requires Concord to pretreat industrial waste. This is accomplished by requiring their industrial customers to pre-treat their discharges to the system. Service charges and contributions to capital costs by Concord since fiscal year 2007-08 are set forth in the following table.

The District and the City of Concord are also parties to an Agreement for Sewer Services dated July 22, 1968. Under this agreement, the City of Concord provides disposal and treatment of the sewage generated by a 28.7-acre portion of the District's service area in Walnut Creek. The District is responsible for maintaining and repairing all sewer lines, mains and laterals within the affected area, and it bills and collects all connection charges 28 August 2, 2018 Regular Board Meeting Agenda Packet- Page 158 of 253 Page 131 of 183 and sewer service charges and pays the amount collected to the City of Concord. In fiscal year 2016- 17, the District paid $35,418 of sewer service charges to the City of Concord for the affected area. Billing and Collection of Sewer Service Charges Chapter 6.12 of the District's Code of the District provides for the establishment of sewer service charges, collection procedures, penalties for delinquency, and uses of funds. General Policy. The purpose of the sewer service charge is to raise revenue for the cost of maintenance and operation of sewerage facilities used for the collection, treatment, and disposal of sewage from residential, commercial, institutional, and industrial users within the District, payment of principal and interest on borrowings, and capital recovery costs in accordance with federal and State Revenue Program Guidelines. Collection of Charges on Tax Roll. Pursuant to provisions of Division 5, Part 3, Chapter 6, Article 4 of the California Health and Safety Code,the District elected to have all sewer service charges for each year, commencing with fiscal year 1976-77, collected on the tax roll. To effectuate this billing, the District prepares and files with the District Secretary a written report containing a description of each parcel and the amount of the sewer service charge for the forthcoming fiscal year. Following the publication of notice of the filing of the report and the time, date, and place a public hearing, the Board of Directors hears and considers all objections or protests to the report. Upon conclusion of the hearing, the Board of Directors may adopt, revise, change, reduce, or modify any charge or overrule any and all objections and will make its determination upon each charge, which determination is final. A copy of the report adopted by the Board of Directors must be filed with the Auditor of Contra Costa County on or before August 10 of each year. The Tax Collector of Contra Costa County includes the amount of the sewer service charge on bills for taxes levied against the respective lots and parcels of land. The first and second installments due on November 1 and February 1 of each year, respectively become delinquent if not paid by December 10 and April 10 of each year, respectively. The District's sewer service charge constitutes a lien, as of the lien date for general property taxes, on the lot or parcel of land against which the charge has been imposed. All laws applicable to the levy, collection, and enforcement of general property taxes are applicable to the District's sewer service charge, including those pertaining to delinquency, correction, cancellation, refund, and redemption. With respect to those properties that are not subject to taxation, Ordinance No. 117, Section 11-705 provides that the District will mail to the owner of the parcel a sewer service charge bill which is due and payable in two installments on November 1 and February 1 of each year and which becomes delinquent if not paid by December 10 and April 10 of each year. Enforcement. In the event of the failure of any owner to pay when due any sewer service charge applicable to a parcel, the District may enforce payments of such delinquent charges in any of the following manners: • The District may have the parcel disconnected from the sanitary sewer system. In the event the disconnection should create a public hazard or nuisance, the General Manager or authorized representatives may enter upon the parcel for the purpose of doing such things as may be reasonably necessary to alleviate or remove the hazard or menace.The owner of the parcel has a duty to reimburse the District for all expenses incurred by the District in disconnecting any such parcel. No reconnection is made until all charges are paid. 29 August 2, 2018 Regular Board Meeting Agenda Packet- Page 159 of 253 Page 132 of 183 • The District may institute action in any court of competent jurisdiction to collect any charges, penalties, and interest which may be due and payable to the same manner as any other debt owing to the District may be collected. • Any and all delinquent payments may be placed on the tax roll and collected with the property taxes, as provided in Ordinance No. 117. • Such other action may be taken as may be authorized by law and the Board. Billings and Delinquencies. A history of billings and collections by the District for sewer service, which is levied on the property tax bill, is set forth in the following table.

The charge for commercial users consists of an annual rate based on a measured volume of water usage per 100 cubic feet(HCF). (2) Beginning in fiscal year 1992-93 the District's Sewer Service Charge"Capital"increment started, and allocated for capital improvements. (3) Allocation of Sewer Service Charge to Capital is increased. O&M allocation reduced due to drawdown of O&M reserve in FY2018-19 versus contributions to O&M reserve in FY2017-18.

Currently the District charges a Capacity Fee of $6,700 per residential unit equivalent ("RUE") for all new customers. New customers in areas where wastewater pumping stations are needed to reach the District's gravity fed sewers are instead charged a Pumped Zone Fee totaling $8,336 per RUE. A RUE is the capacity demand placed on the system by a discharge of 200 gallons per day of"standard" domestic wastewater. Capacity Fees for nonresidential customers are based on a calculation of the customer's capacity demand, in RUEs, which takes both wastewater flow and strength into account. Payment of Capacity Fees are due prior to the issuance of a permit for connection of the new customer's parcel to the sewer system. For existing customers who change the use of their property or build additions to existing uses which impose an added capacity burden on the District's facilities, Capacity Fees for the added burden are due prior to the issuance of a building permit by the appropriate building code enforcement agency. 34 August 2, 2018 Regular Board Meeting Agenda Packet- Page 164 of 253 Page 137 of 183 The following table summarizes current and historical Capacity Fees.

The Board of Supervisors of Contra Costa County has adopted the Alternative Method of Distribution of Tax Levies and Collections and of Tax Sale Proceeds (the "Teeter Plan"), as provided for in Section 4701 et seq. of the California Revenue and Taxation Code. As a result, the District can expect to receive its share of the ad valorem property tax levy based on the amount levied rather than the amount collected. Regulatory Matters Treatment Plant. The District is subject to the Federal Water Pollution Control Act, as amended (the "Clean Water Act"), and the State of California Porter Cologne Water Quality Control Act of 1969, as amended. Both federal and State regulations regulate the quality of effluent discharged from the Treatment Plant and the disposal of sewage sludge from the Treatment Plant. 36 August 2, 2018 Regular Board Meeting Agenda Packet- Page 166 of 253 Page 139 of 183 Wastewater discharge criteria are currently established with respect to the Treatment Plant under Order No. R2-2017-0009 (NPDES No.CA0037648) of the California Regional Water Quality Control Board, San Francisco Bay Region. The Order expires on May 31, 2022. The District's discharge of mercury to San Francisco Bay is regulated by Order R2-2017- 0041 (NPDES No. CA0038849) of the California Regional Water Quality Control Board, San Francisco Bay Region. The Order expires on December 31, 2022. The District is subject to a regional permit, also issued by the California Regional Water Quality Control Board, San Francisco Bay Region, Waste Discharge Requirements For Nutrients From Municipal Wastewater Dischargers To San Francisco Bay, Order No. R2-2014-0014 (NPDES No. CA0038873). The Order expires June 30, 2019. The District also operates the Treatment Plant under a Major Facility Review Permit (Tile V) from the Bay Area Air Quality Management District. This Permit expires on March 11, 2020. The District's record of 20 consecutive years of 100% compliance with the Treatment Plant NPDES Permit was recently recognized by the National Association of Clean Water Agencies with their Platinum-20 Peak Performance Award—a distinction earned by only a handful of wastewater agencies nationwide. To receive this award, the District met stringent federal, State and regional water quality standards when collecting, sampling, treating, testing and releasing wastewater every day for the past 20 years without a single violation of its EPA-issued discharge permit. HHW Collection Facility. In connection with operation of the HHW Collection Facility, the District operates under an Annual Business Authorization Permit from the Contra Costa Health Services– Hazardous Materials Program. The District's current Permit expires on June 30, 2019. Recycled Water Program. In connection with its Recycled Water Program,which is regulated under California Code of Regulations, Title 22, Division 4, Section 60301 et seq., the District operates under a Letter of Approval –Water Reuse Program Order 96-011 issued by the California Regional Water Quality Control Board, San Francisco Bay Region effective May 9, 1997. The permit provides for self-monitoring and does not have a stated expiration date. DISTRICT FINANCES Financial Statements The District is a proprietary entity, it uses an enterprise fund format to report its activities for financial reporting purposes. Enterprise funds are used to account for operations that are financed and operated in a manner similar to private business enterprises, where the intent of the governing body is that the costs and expenses, including depreciation, of providing goods or services to the general public on a continuing basis be financed or recovered primarily through user charges; or where the governing body has decided that period determination of revenues earned, expenses incurred, and net income are appropriate for capital maintenance, public policy, management control, accountability, or other purposes. Enterprise funds are used to account for activities similar to those in the private sector, where the proper matching of revenues and costs is important and the full accrual basis of accounting is required. With this measurement focus, all assets and liabilities of the enterprise are recorded on its balance sheet, all revenue are recognized when earned and all expenses, including depreciation, are recognized when incurred. Enterprise fund equity includes retained earnings and contributed capital. 37 August 2, 2018 Regular Board Meeting Agenda Packet- Page 167 of 253 Page 140 of 183 The District's enterprise fund is managed using four sub-funds, Operating & Maintenance (also known as "Running Expense"), Sewer Construction, Self-Insurance, and Debt Service.

Capital Improvement Plan General. Each year,the District develops an update to the ten-year Capital Improvement Plan. The Ten-Year CIP is a "road map"for the upcoming and future District's capital facilities and financing needs. Specifically, the plan identifies and prioritizes capital projects needed to accomplish Central San's Vision, Mission, Values and Goals. The current plan incorporates the recommendations from the June 2017 Comprehensive Wastewater Master Plan (CWMP). It also includes cost estimates for proposed project work and projections for the various sources of revenue needed to meet the cash flow requirements of the Plan. The principal purpose of the Ten-Year CIP is to provide the Board with the information needed to formulate long-range policy regarding: • Priority and Schedule— Identify, prioritize, and schedule the projects necessary to accomplish Central San's Vision, Mission, Values and Goals. • Financing — Plan for sufficient financial resources to complete the proposed projects. Current Capital Improvement Plan. The District's current Capital Improvement Plan covers the ten-year period from fiscal year 2018-19 through 2027-28. The plan includes projected expenditures totaling approximately $805.8 million (2018 dollars). Capital improvement projects are grouped into four programs: Treatment Plant, Collection System, General Improvements, and Recycled Water. Below is a brief discussion of each 10-year program. A summary of the next 10 years of planned expenditures by program, without inflation, is contained in a subsequent table. • Treatment Plant Program: The Treatment Plant Program will require $428.2 million (2018 dollars), comprising 53.1% of the District's capital improvements over the next ten years. The Treatment Plant Program includes projects that will address aging infrastructure needs, meet regulatory requirements, address any hydraulic or process capacity deficiencies, and improve sustainability or help meet sustainability related goals. The emphasis of the Ten-Year CIP—Treatment Plant Program will be on the repair and replacement of aging treatment plant infrastructure, improving existing facilities to ensure reliable compliance with increasingly stringent regulatory requirements, improving the resiliency of existing facilities against security threats and natural hazards such as seismic and flooding events, and improving overall energy efficiency. Treatment plant programs are grouped into three subcategories: 1) Liquid Treatment Process; 2) Solids Handling Process; or 3) General Treatment Plant and Safety Improvements. • Collection System Program:The Collection System Program includes projects that will address aging and deteriorating infrastructure needs, meet regulatory requirements, address any capacity deficiencies, and improve sustainability or help meet sustainability related goals. At $309 million (2018 dollars), the Collection System Program comprises 38.3% of the District's capital improvements over the next 10 years. The emphasis of the Ten-Year CIP — Collection System Program will be on rehabilitating and replacing deteriorating sewers, new development and sewer expansion paid by developers within Central San's service area, upgrading aging pump stations, and implementing large diameter and force main inspection programs. The inspection programs will help to update the condition of existing infrastructure and to confirm the timing and cost of rehabilitation or replacement of 40 August 2, 2018 Regular Board Meeting Agenda Packet- Page 170 of 253 Page 143 of 183 large diameter sewers and force mains. Overall, these projects are targeted at reducing the risk of SSO's in the District's collection system. Collection System program projects have been grouped into one of four subcategories: 1) Collection System Rehabilitation and Replacement (R&R); 2) Pump Stations; 3) Regulatory Compliance; 4) Contractual Assessment Districts (CADS) and Development Sewerage. General Improvements Program: The General Improvements Program will require $25.4 million (2018 dollars), representing 3.1% of the District's anticipated capital expenditures over the next 10 years. The General Improvement Program includes projects that will address aging infrastructure needs, meet regulatory requirements, and improve sustainability or help meet sustainability related goals. This includes implementing property and building improvements, addressing equipment needs, acquiring new properties if required, completing development of the Asset Management Program, information management system and data management system upgrades, general security improvements enhancement, and cyber security. Many of the District's building are over 25 years of age and are starting to require general building upgrades to both the interior and exterior of the buildings such as painting, replacing ceiling tiles, upgrading fixtures, replacing roofs, replacing worn furniture and other equipment, and upgrading buildings to meet current seismic standards. The emphasis of the General Improvement Program for the Ten-Year CIP will be on upgrading many of those aging buildings. In addition, the District will continue to require routine acquisition of new equipment, vehicle replacement, security improvements, and information technology improvements, and improved cyber security enhancements. General Improvements Program projects have been grouped into one of six sub-project categories: 1) Vehicles Replacement Program; 2) Equipment Acquisition; 3) Information Technology Development; 4) Building and District Property; 5) Capital Project Legal Services; and 6) Asset Management Program Development. • Recycled Water Program: The District's Recycled Water Program includes projects that will require $23.7 million (2018 dollars), comprising 2.9% of the District's capital improvements over the next 10 years. The Recycled Water Program includes projects that will address aging infrastructure needs, meet regulatory requirements, address any capacity deficiencies, and improve sustainability or help meet sustainability related goals. The emphasis of the Ten-Year CIP — Recycled Water Program will be on continued expansion of the Zone 1 Recycled Water Program in support of Board Policy 019 - Recycled Water, implementing improvements to the existing recycled water filter plant and related support facilities to address aging infrastructure to ensure reliable supply of recycled water, replacing and installing new clear well liner and covers, and initiating ongoing rehabilitation and replacement of recycled water distribution system assets. District staff will continue to explore and plan for other potential recycled water projects and related improvements and expansions that may be required. These other projects will likely involve the wholesale of recycled water to a water purveyor in the future. Ten-Year CIP Drivers Projects included in the CIP address one of more of the four major drivers for implementing capital improvement projects: 1) Aging Infrastructure; 2) Regulatory; 3) Capacity; and 4) Sustainability. Most project scopes include several project elements that address a range of drivers which include: 41 August 2, 2018 Regular Board Meeting Agenda Packet- Page 171 of 253 Page 144 of 183 • Aging Infrastructure: Projects required to maintain the performance and reliability of existing assets to ensure reliable conveyance and treatment of wastewater. Most of the existing treatment plant facilities were constructed in the late 1970s and early 1980s following the passing of the Clean Water Act, and some of the collection system facilities and piping were constructed as early as the 1940s and 1950s. • Regulatory: Projects required to reliably comply with regulatory requirements that are designed to protect human health and the environment, and includes planning needed to anticipate potential future regulatory requirements. Regulatory drivers that may trigger capital improvement projects include potential changes in future state and/or federal water, air, and solids regulations. Potential regulatory drivers include: changes to existing final effluent limits to address nutrients, selenium, contaminants of emerging concern, and others; changes to California/National Toxics Rules, 303(d) listed pollutants and micropollutants, and new virus-based disinfection criterion; reductions in greenhouse gas emission Cap and Trade Program thresholds; compliance with Federal 129 sewage sludge incineration rules, changes to air emission limits, and solids handling/management and disposal regulations; recycled water, including potential coordinated projects with water agencies on Title 22, indirect, and even indirect or direct potable reuse opportunities; and collection system regulatory requirements such as the reduction of sewer system overflows (SSOs). Occasionally, improvements are also required to improve the reliability of existing facilities to ensure 100 percent compliance with regulatory permits and to ensure protection of human health and the environment. • Capacity: Projects required to increase capacity of existing facilities. Capacity drivers that may trigger capital improvement projects include potential upgrades required to mitigate hydraulic bottlenecks and increase capacity of existing facilities to accommodate wastewater flows and loads. Projects that would be required to accommodate planned growth are not included in the CIP. • Sustainability/Energy/Optimization: Projects to minimize life-cycle costs, maximize benefits, and achieve economic stability through optimization, resiliency, resource recovery, and energy projects. Sustainability drivers that may trigger capital improvement projects include upgrades to strive towards net zero energy, recycled water projects to ensure the reliable supply of recycled water for use at the District or by customers, and upgrades to improve the resiliency of District facilities. Improvements to strive towards net zero energy or energy self-sufficiency include energy efficiency measures such as installing more energy efficient equipment or treatment processes, and renewable energy projects such as solar or wind. 2017 Comprehensive Wastewater Master Plan (CWMP). The foundation for the 10-year CIP was the CWMP which was completed in June 2017. The CWMP provided an updated Capital Improvement Plan for a 20-year planning horizon. The CWMP included descriptions, rationales, and estimated costs for collection system and wastewater treatment plant capital improvement projects and on-going programs to address aging infrastructure, meet existing and anticipated regulatory requirements, accommodate planned growth, optimize energy use, and implement the District's vision for the treatment plant that is consistent with the District's Strategic Plan. The CWMP was to serve as a tool for maintaining a high level of service, establishing long-term fiscally responsible policies for customers, and providing a clear direction for the District. Some of potential future projects identified in the CWMP are not currently included in the 10- year CIP. The CIP will be updated annually as the need for such projects is clarified. These future projects are not included in the CIP and amount to about $920 million, of which approximately $510 million may be within the next 20 years. These projects include the following: 42 August 2, 2018 Regular Board Meeting Agenda Packet- Page 172 of 253 Page 145 of 183 • Nutrient Removal BACWA (Bay Area Clean Water Agencies) Levels 2/3: Possibly beyond 20 years ** • Recycled Water Exchange (Refinery Recycled Water) Project-20 million gallons per day (MGD) * • Advanced Treatment/Contaminants of Emerging Concern Removal ** • Renewable Energy Projects (triggered by increased power demands from nutrient removal) ** • Concord Community Reuse Project (CCRP) Recycled Water Facilities Improvements * • CCRP Collection System Improvements • CCRP Recycled Water Distribution System (Central San current plan is to wholesale recycled water, so distribution system was not evaluated or included in CIP) * Projects expected to be cost neutral to Central San. ** Projects identified but not currently required by regulations. The table on the following page shows the District's current CIP, covering Fiscal Years 2018-19 through 2027-28. 43 August 2, 2018 Regular Board Meeting Agenda Packet- Page 173 of 253 oV- O 00 O V- M O 00 O O DO O O O O CD O M O N LOCD H ~ N~ 00 M LONO ti 0O O O O 0 CD O O OA O DO O O O ti O CV OpO" CD CD O O LO I` O N O N Ln ti Nt M ' � j 000 f- O (D N O CD O L) O LO LO LO O C r-- A Cp OM00 O O O Ln p r-- 00 ` 00f` CD O N O O C� Do r- N O C1} Nt N Cl) O Nt N LO M M O 6 N N N N CD Ef} Ef} Ef} Cl) DO EA 64)- 00 AOp m O CD (D C DO DOOCD f` NM 0 N0 E~A Oj � LC) Op 'r LO O O OO O O O 00 O M O CO00 O O O O O O LO O It OCO O LO 0 CII) LO O O Lf! 00 Lo O DODO 00 O V- CA � N LO 0 DO to LO O0 DO p O ( 0')N Ln O M CD M N N N NtEE} V- V- 64)- O N N O � CD M O N O U) EDAo CD ti N O OO OO DO OO O O CO 00 CD O DO N Ln p LO M 0p p p n OCO p N 0 U) LOO DO O O CD Ln ~ O L ( ti O O CCDO N O O M O Nt p CD N O M o LO 1 O N m LO ~ O � O (D 0') T- O LO N M N I` LO N (Y EA 64y N ( EA N EA O O CD r CA DOO 1,*- O N ff� 00 ti CD O 00 O Cq O M O O 0 O 0 O O DO L� N M O NO cq It CD M LOO OM ti O 1 T" CD N N M N M ti O N O O LO EA O NNt00 EA fA N � N � � ti O CD DO O O It It NO O p O O 00 00 O 00 O O O t0 mO O OLn 4 O m t0 O Oo M O tiO O Co O Lf) ~ Lf) m O O M CD M (Oq ti N Oo CD O DO ~ O CD N O CD co 00 00 O O N O p ti MEA N LO co NEA N N Nt � fA LO N EA U I.L No LO o m CDLO o M O Nt 0 � o 0 o p O O O � CD Iq N co Ln 00 f` O 00 O M O O O O O O a Do I` LO OLr� O N N Do Ln 00 Do CD O co mO N O O ad, o N N N M O M N co OM V) 0M NN � LO EA CD co N ti Q EA cq N 64)-A EA - a.

The Ten-Year CIP anticipates funding from revenue(Sewer Service Charge,Ad Valorem Taxes, Capacity Fees) and external financing. The Ten- Year CIP is currently funded on a year-by-year basis when the capital improvement budget for the forthcoming fiscal year is formally authorized and adopted by the Board. Changes in capital revenue forecasts or changes in recommended expenditures may result in changes to the Ten-Year CIP. The District has developed and maintained a capital fee system, which equitably divides the cost obligations of the capital program between the existing customers of District facilities and new customers of these facilities. Under this "fair share" approach, existing customers (primarily through property taxes and a capital component of the annual sewer service charge) and new users (through capacity fees based on a proportional "buy-in" to the current value of all existing capital assets) fund facilities upgrade, renovation and replacement costs as well as expansion projects needed to accommodate growth. The Board has a long-standing preference for pay-as-you-go financing for routine collection system work, where such work is to be funded from current year revenue sources and reserves. This approach is described in the District's Debt Management policy, adopted in 2017. That policy does permit financing of capital projects but sets parameters for the maximum portion of the Capital Improvement Plan to be financed over a ten-year period, the duration of such financing and other factors. Prospectively, the only controllable source of revenue for the District is the Sewer Service Charge, the rates of which are subject to Proposition 218 requirements. Thus, any reduction in capital revenue from other sources, such as capacity fees, would have to be made up by an increase in the Sewer Service Charge, by a like reduction in expenditures on the capital program, or by borrowing. The District expects to finance a portion of the Capital Improvement Plan shown in fiscal year 2019- 20 and beyond with debt financing. Financing of capital projects, apart from pay-as-you -go financing, may take the form of State Revolving Fund loans (to the extent the District successfully is awarded such loans), or other debt obligations such as future revenue bond issuances. 45 August 2, 2018 Regular Board Meeting Agenda Packet- Page 175 of 253 Page 148 of 183 Historical Net Revenues, Tax Revenues and Debt Service Coverage The following table sets forth revenues, expenses and debt service coverage figures for fiscal years 2012-13 through 2016-17.

Projected Net Revenues, Tax Revenues and Debt Service Coverage The following table sets forth the District's projected Net Revenues, Tax Revenues, debt service and debt service coverage for the fiscal years ending June 30, 2019 through June 30, 2022. The projections are based on the following assumptions. Rate Base Growth: The projections assume an approximately 0.31-0.35% annual increase in the Wastewater System rate base, i.e., number of customers. Rate adjustments: The projections assume the following rate increases in sewer service charges: (i) 7% in fiscal year 2019-20, (ii) 7% in fiscal year 2020-21, (iii) and 6% in fiscal year 2021- 22. The District can provide no assurances it will be able to increase rates as projected. See "RISK FACTORS— Proposition 218." Expenses: The projections assume annual operation and maintenance expenses of the Wastewater System will increase/(decrease) as follows: (i) (0.4%) in fiscal year 2019-20, (ii) 5.1% in fiscal year 2020-21, (iii) 4.6% in fiscal year 2021-22 Debt:The projections assume new money debt issuances of: (i)$50 million in fiscal year 2019- 20, (ii) $135 million in fiscal year 2021-22. Such debt issuances are subject to Board approval and bond market conditions and acceptance. Property Tax Revenues:The projections assume an 2.5% increase in assessed values in fiscal year 2019-20, 3.0% annual increases from fiscal years 2020-21 through 2021-22. Interest earnings: The projections assume interest earnings on District funds as follows: (i) 1.25% in fiscal year 2019-20, (ii) 1.50% in fiscal year 2020-21, and (iii) 2.00% in fiscal year 2021- 22. The financial forecast represents the District's estimate of projected financial results based upon its judgment of the most probable occurrence of certain important future events. Actual operating results achieved during the projection period may vary from those presented in the forecast and such variations may be material. The pledge of revenues of the District with respect to the Bonds under the Indenture is limited to Net Revenues and Tax Revenues, and the District is not obligated to apply any other revenues to pay the Bonds. 47 August 2, 2018 Regular Board Meeting Agenda Packet- Page 177 of 253 Page 150 of 183 TABLE 17 CENTRAL CONTRA COSTA SANITARY DISTRICT Budgeted and Projected Revenues and Expenses (in $000's except service data and coverage) Budget Projections 2017-18 2018-19 2019-20 2020-21 2021-22 Gross Revenues Sewer services charges $751221 $671074 $851937 $921266 $981143 Sewer charges-City of Concord 151200 141800 151630 161399 171247 Permit and inspection fees 11724 11783 11836 11892 11948 Interest income 78 600 548 655 911 Other service charges 2,436 _ 2,669 2,749 _ 2,832 _ 2,916 Total Gross Revenues $941659 $861926 $1061700 $1141044 $1211165 Operation and Maintenance Costs') Sewage collection $171076 $161895 $191092 $201049 $211091 Sewage treatment 271023 261502 301019 311557 331218 Engineering 171034 171033 171125 181063 191102 Recycled Water 11319 11553 11181 11236 11295 Administrative and general 27,262 _ 27,738 _ 21,909 _ 23,013 _ 23,562 Total Operation and Maintenance Costs $891714 $891721 $891326 $931918 $981268 Total Operating Income (Loss) $41945 $(21795) $171374 $201126 $221897 Non-Operating Revenue Sewer service charges (capital) $121100 $271926 $151857 $171024 $181109 Capital charges- City of Concord 61000 71150 111706 191849 181334 Interest earnings (capital reserve) 386 570 676 890 955 Capacity Fees (Connection fees) 61413 61500 71594 71917 81258 Other Income(2) 462 443 452 461 470 Total Non-Operating Revenues: $251361 $421589 $361285 $461141 $461126 Tax Revenues $151874 $161835 $171249 $171767 $181300 Maximum Annual Debt Services (Net of $31790 $31584 $51116 $61657 $111038 Refundable Credits) Debt Service Coverage Net Revenues+Tax Revenues('' $461180 $561629 $701908 $841034 $871323 Debt Service Coverage 12.18x 15.80x 13.86x 12.62x 7.91 x Adjusted Net Revenues+Tax Revenues(EI) $331767 $421979 $511608 $561268 $601731 Debt Service Coverage 8.91x 11.99x 10.09x 8.45x 5.50x (1) Consistent with the definition of Operation and Maintenance Costs, this "Operation and Maintenance Costs" category does not include depreciation.

Demand and Usage There can be no assurance that the local demand for services provided by the Wastewater System will continue according to historical levels. Reduction in the level of demand could require an increase in rates or charges in order to produce Net Revenues sufficient to comply with the District's rate covenants in the Indenture. Such rate increases could increase the likelihood of nonpayment, and could also further decrease demand. In addition, drought conditions and voluntary or mandatory conservation measures could decrease usage of the services of the Wastewater System. Reduction in usage could require an increase in rates or charges in order to produce Net Revenues sufficient to comply with the District's rate covenants. Expenses There can be no assurance that Operation and Maintenance Costs of the Wastewater System will be consistent with the levels described in this Official Statement. Changes in technology, increases in the cost of energy or other expenses and increased regulatory requirements (including increased regulation of treated wastewater discharge and emissions from the HHW Collection Facility) would reduce Net Revenues, and could require substantial increases in rates or charges in order to comply with the rate covenant. Such rate increases could increase the likelihood of nonpayment, and could also decrease demand. Property Taxes The amount of Tax Revenues is dependent upon assessed values and property tax collections in the District. Decreases in assessed values(whether as a result of assessment appeals or otherwise) and increased property tax delinquencies will result in reduced Tax Revenues. In addition, the amount of Tax Revenues is dependent upon State action. In previous years the State has reallocated ad valorem property tax revenues from local agencies such as the District. On November 2, 2004, California voters approved Proposition 1A, which amended the State constitution to significantly reduce the State's authority over major local government revenue sources. Under Proposition 1A, the State cannot, without providing replacement funding, (i) reduce local sales tax rates or alter the method of allocating the revenue generated by such taxes, (ii)shift property taxes from local governments to schools or community colleges, (iii) change how property tax revenues are shared among local governments without two-third approval of both houses of the State Legislature or (iv) decrease Vehicle License Fee revenues without providing local governments with equal replacement funding. Proposition 1A allows the State to borrow up to 8% of total local property tax revenues during a fiscal emergency declared by the Governor. The funds must be repaid within three years, or the State cannot borrow again for 10 years. Future Parity Obligations Although the District has covenanted not to issue additional obligations payable from Net Revenues and Tax Revenues on a senior basis to the Bonds, the Indenture permits the issuance by the District of certain obligations that may have a lien upon the Net Revenues and Tax Revenues which is on a parity basis to the lien which secures the Bonds (see "SECURITY FOR THE BONDS — Parity Obligations" above). 50 August 2, 2018 Regular Board Meeting Agenda Packet- Page 180 of 253 Page 153 of 183 The coverage tests described in "SECURITY FOR THE BONDS—Parity Obligations" involve, to some extent, projections of Net Revenues and Tax Revenues. If such indebtedness is issued, the debt service coverage for the Bonds could be diluted below what it otherwise would be. Moreover, there is no assurance that the assumptions that form the basis of such projections, if any, will be actually realized subsequent to the date of such projections. If such assumptions are not realized, the amount of future Net Revenues and Tax Revenues may be less than projected, and the actual amount of Net Revenues and Tax Revenues may be insufficient to provide for the Bonds and such Parity Obligations. No Reserve Fund The District is not funding a reserve fund for the Bonds. Accordingly, if Tax Revenues and Net Revenues are insufficient to make debt service payments on the Bonds and any Parity Obligations, Bondholders may not receive all amounts due to them. Natural Disasters The District, like all California communities, is likely to be subject to unpredictable seismic activity, fires or floods. If there were a severe seismic, flood or fire event in the District, there could be substantial damage to and interference with the District and its facilities, which could increase the District's Operation and Maintenance Costs. In addition, widespread damage in the District's service area from natural disasters could results in declines in both Gross Revenues and Tax Revenues. Decreased Net Revenues and Tax Revenues could adversely impact the District's ability to pay principal and interest with respect to the Bonds. Seismic Activity. The District is located in an area of high seismic risk because it is adjacent to a major tectonic plate interface (the San Andreas fault) between the North American and Pacific crustal plates. In addition to the main trace of the San Andreas Fault, stresses resulting from movements along the plate interface are relieved by earthquakes occurring on many smaller branches throughout the Bay Area. There are several faults in the area that might be sources of significant ground shaking, including the San Andreas (50 kilometers away), San Gregario (65 kilometers away), Hayward (24 kilometers away), Calaveras (15 kilometers away) and Concord/Green Valley (2 kilometers away). The District has invested in various seismic retrofitting projects to improve the resiliency of its facilities in light of these risks. Further projects are planned in the Ten Year capital improvement plan (discussed above under "DISTRICT FINANCES —Capital Improvement Plan"). Flooding Hazards. The District's Treatment Plant is subject to flooding from Walnut Creek as a result of 500-year flood elevations; in 2008, the District completed flood control measures in combination with the Contra Costa County Flood Control District to protect the Treatment Plant during 100-year flood events. The Treatment Plant is subject to flooding from storm precipitation within the local drainage areas. Fire Hazards. Wildland fires are a seasonal occurrence in California and are a risk in the less densely-populated portions of the service area. Proposition 218 General. On November 5, 1996, California voters approved Proposition 218, the so- called "Right to Vote on Taxes Act." Proposition 218 added Articles XIIIC and XIIID to the State Constitution, which affect the ability of local governments to levy and collect both existing and future taxes, assessments, and property-related fees and charges. Proposition 218, which generally became effective on November 6, 1996, changed, among other things, the procedure for the imposition of any new or increased property-related "fee" or "charge," which is defined as "any levy other than an ad valorem tax, a special tax or an assessment, imposed by a (local government) upon a parcel or upon 51 August 2, 2018 Regular Board Meeting Agenda Packet- Page 181 of 253 Page 154 of 183 a person as an incident of property ownership, including user fees or charges for a property related service" (and referred to in this section as a "property-related fee or charge"). Specifically, under Article XIIID, before a municipality may impose or increase any property- related fee or charge, the entity must give written notice to the record owner of each parcel of land affected by that fee or charge. The municipality must then hold a hearing upon the proposed imposition or increase at least 45 days after the written notice is mailed, and, if a majority of the property owners of the identified parcels present written protests against the proposal, the municipality may not impose or increase the property-related fee or charge. Further, under Article XIIID, revenues derived from a property-related fee or charge may not exceed the funds required to provide the "property-related service" and the entity may not use such fee or charge for any purpose other than that for which it imposed the fee or charge. The amount of a property-related fee or charge may not exceed the proportional cost of the service attributable to the parcel, and no property-related fee or charge may be imposed for a service unless that service is actually used by, or is immediately available to, the owner of the property in question. Article XIIID is the basis for the limitations on the use of Water System Net Revenues and Sewer System Net Revenues described in "SECURITY FOR THE BONDS — Pledge of Net Revenues and Tax Revenues." In addition, Article XIIIC states that "the initiative power shall not be prohibited or otherwise limited in matters of reducing or repealing any local tax, assessment, fee or charge. The power of initiative to affect local taxes, assessments, fees and charges shall be applicable to all local governments and neither the Legislature nor any local government charter shall impose a signature requirement higher than that applicable to statewide statutory initiatives." Judicial Interpretation of Proposition 218. After Proposition 218 was enacted in 1996, appellate court cases and an Attorney General opinion initially indicated that fees and charges levied for water and wastewater services would not be considered property-related fees and charges, and thus not subject to the requirements of Article XIIID regarding notice, hearing and protests in connection with any increase in the fees and charges being imposed. However, three recent cases have held that certain types of water and wastewater charges could be subject to the requirements of Proposition 218 under certain circumstances. In Richmond v. Shasta Community Services District (9 Cal. Rptr. 3rd 121), the California Supreme Court addressed the applicability of the notice, hearing and protest provisions of Article XIIID to certain charges related to water service. In Richmond, the Court held that connection charges are not subject to Proposition 218. The Court also indicated in dictum that a fee for ongoing water service through an existing connection could, under certain circumstances, constitute a property-related fee and charge, with the result that a local government imposing such a fee and charge must comply with the notice, hearing and protest requirements of Article XIIID. In Howard Jarvis Taxpayers Association v. City of Fresno (March 23, 2005), the California Court of Appeal, Fifth District, concluded that water, sewer and trash fees are property-related fees subject to Proposition 218 and a municipality must comply with Article XIIID before imposing or increasing such fees. The California Supreme Court denied the City of Fresno's petition for review of the Court of Appeal's decision on June 15, 2005. In July 2006 the California Supreme Court, in Bighorn-Desert View Water Agency v. Verjil (S127535, July 24, 2006), addressed the validity of a local voter initiative measure that would have (a) reduced a water agency's rates for water consumption (and other water charges), and (b) required the water agency to obtain voter approval before increasing any existing water rate, fee, or charge, or imposing any new water rate, fee, or charge. The court adopted the position indicated by its statement in Richmond that a public water agency's charges for ongoing water delivery are "fees and charges" within the meaning of Article XIIID, and went on to hold that charges for ongoing water delivery are 52 August 2, 2018 Regular Board Meeting Agenda Packet- Page 182 of 253 Page 155 of 183 also "fees" within the meaning of Article XIIIC's mandate that the initiative power of the electorate cannot be prohibited or limited in matters of reducing or repealing any local tax, assessment, fee or charge. Therefore, the court held, Article XIIIC authorizes local voters to adopt an initiative measure that would reduce or repeal a public agency's water rates and other water delivery charges. (However, the court ultimately ruled in favor of the water agency and held that the entire initiative measure was invalid on the grounds that the second part of the initiative measure, which would have subjected future water rate increases to prior voter approval, was not supported by Article XIIIC and was therefore invalid.) The court in Bighorn specifically noted that it was not holding that the initiative power is free of all limitations; the court stated that it was not determining whether the electorate's initiative power is subject to the statutory provision requiring that water service charges be set at a level that will pay for operating expenses, provide for repairs and depreciation of works, provide a reasonable surplus for improvements, extensions, and enlargements, pay the interest on any bonded debt, and provide a sinking or other fund for the payment of the principal of such debt as it may become due. Compliance by the District with Proposition 218. The District's most recent sewer rates were adopted in compliance with the Bighorn decision. See "THE DISTRICT— Billing and Collection of Sewer Service Charges." The District will continue to comply with the provisions of Proposition 218 in connection with future rate increases. Conclusion. It is not possible to predict how courts will further interpret Article XIIIC and Article XIIID in future judicial decisions, and what, if any, further implementing legislation will be enacted. Under the Bighorn case, local voters could adopt an initiative measure that reduces or repeals the District's rates and charges, although it is not clear whether (and California courts have not decided whether) any such reduction or repeal by initiative would be enforceable in a situation in which such rates and charges are pledged to the repayment of bonds or other indebtedness. There can be no assurance that the courts will not further interpret, or the voters will not amend,Article XIIIC and Article XIIID to limit the ability of local agencies to impose, levy, charge and collect increased fees and charges for utility service, or to call into question previously adopted utility rate increases. Limited Recourse on Default If the District defaults on its obligation to pay the Bonds, the Trustee has the right to accelerate the total unpaid principal amounts of the Bonds. However, in the event of a default and such acceleration there can be no assurance that the District will have sufficient Net Revenues and Tax Revenues to pay the accelerated amounts due on the Bonds. Limitations on Remedies Available; Bankruptcy The enforceability of the rights and remedies of the owners of the Bonds and the obligations of the District may become subject to the following: the federal bankruptcy code and applicable bankruptcy, insolvency, reorganization, moratorium, or similar laws relating to or affecting the enforcement of creditors' rights generally, now or hereafter in effect; equitable principles which may limit the specific enforcement under State law of certain remedies; the exercise by the United States of America of the powers delegated to it by the federal Constitution; and the reasonable and necessary exercise, in certain exceptional situations, of the police power inherent in the sovereignty of the State and its governmental bodies in the interest of servicing a significant and legitimate public purpose. Bankruptcy proceedings, or the exercising of powers by the federal or State government, if initiated, could subject the owners to judicial discretion and interpretation of their rights in bankruptcy or otherwise and consequently may entail risks of delay, limitation, or modification of their rights. 53 August 2, 2018 Regular Board Meeting Agenda Packet- Page 183 of 253 Page 156 of 183 Limited Obligation The District's obligation with respect to the Bonds is a special obligation of the District payable solely from Net Revenues and Tax Revenues and other funds provided for in the Indenture. Although Tax Revenues includes ad valorem property taxes allocated to the District, the District has not agreed to levy any form of taxation to pay the Bonds. The obligation of the District to pay the Bonds does not constitute a debt or indebtedness of any city, county, the State of California or any of its political subdivisions, within the meaning of any constitutional or statutory debt limitation or restriction. Change in Law In addition to the other limitations described in this Official Statement, the California electorate or Legislature could adopt a constitutional or legislative property tax decrease or an initiative with the effect of reducing revenues payable to or collected by the District. There is no assurance that the California electorate or Legislature will not at some future time approve additional limitations that could have the effect of reducing the Net Revenues or the Tax Revenues and adversely affecting the security of the Bonds. Loss of Tax Exemption As discussed in this Official Statement under the caption "TAX MATTERS," interest with respect to the Series A Bonds could become includable in gross income for purposes of federal income taxation retroactive to the date the Series A Bonds were issued, as a result of future acts or omissions of the District in violation of its covenants in the Indenture. Should such an event of taxability occur, the Series A Bonds are not subject to a special prepayment and will remain outstanding until maturity or until prepaid under one of the other prepayment provisions contained in the Indenture. CONTINUING DISCLOSURE The District has covenanted for the benefit of owners of the Bonds to provide certain financial information and operating data relating to the District by not later than nine months after the end of the District's fiscal year (which is currently June 30) in each year commencing with the report for fiscal year 2018-19 (the "Annual Report") and to provide notices of the occurrence of certain enumerated events. These covenants have been made in order to assist the Underwriter in complying with Securities Exchange Commission Rule 15c2-12(b)(5) (the "Rule"). The specific nature of the information to be contained in the Annual Report or the notices of material events by the District is set forth in "APPENDIX D— Form of Continuing Disclosure Certificate." [[The District has not failed to comply with all material obligations under its existing continuing disclosure undertakings during the past five years.]] [Under review by Piper Jaffray.] TAX MATTERS Federal Tax Status. In the opinion of Jones Hall, A Professional Law Corporation, San Francisco, California, Bond Counsel, subject, however to the qualifications set forth below, under existing law, the interest on the Series A Bonds is excluded from gross income for federal income tax purposes and such interest is not an item of tax preference for purposes of the federal alternative minimum tax, although, in the case of tax years beginning prior to January 1, 2018, for the purpose of computing the alternative minimum tax imposed on certain corporations, such interest earned by a corporation prior to the end of its tax year in 2018 is taken into account in determining certain income and earnings. The opinions set forth in the preceding paragraph are subject to the condition that the District comply with all requirements of the Internal Revenue Code of 1986, as amended (the "Tax Code") that 54 August 2, 2018 Regular Board Meeting Agenda Packet- Page 184 of 253 Page 157 of 183 must be satisfied subsequent to the issuance of the Series A Bonds. The District has covenanted to comply with each such requirement. Failure to comply with certain of such requirements may cause the inclusion of such interest in gross income for federal income tax purposes to be retroactive to the date of issuance of the Series A Bonds. Interest on the Series B Bonds is not intended to be exempt from federal income taxation. Tax Treatment of Original Issue Discount and Premium. If the initial offering price to the public (excluding bond houses and brokers) at which a Series A Bond is sold is less than the amount payable at maturity thereof, then such difference constitutes "original issue discount" for purposes of federal income taxes and State of California personal income taxes. If the initial offering price to the public(excluding bond houses and brokers) at which a Series A Bond is sold is greater than the amount payable at maturity thereof, then such difference constitutes "original issue premium" for purposes of federal income taxes and State of California personal income taxes. De minimis original issue discount and original issue premium is disregarded. Under the Tax Code, original issue discount is treated as interest excluded from federal gross income and exempt from State of California personal income taxes to the extent properly allocable to each owner thereof subject to the limitations described in the first paragraph of this section. The original issue discount accrues over the term to maturity of the Series A Bond on the basis of a constant interest rate compounded on each interest or principal payment date (with straight-line interpolations between compounding dates). The amount of original issue discount accruing during each period is added to the adjusted basis of such Series A Bonds to determine taxable gain upon disposition (including sale, redemption, or payment on maturity) of such Series A Bond. The Tax Code contains certain provisions relating to the accrual of original issue discount in the case of purchasers of the Series A Bonds who purchase the Series A Bonds after the initial offering of a substantial amount of such maturity. Owners of such Series A Bonds should consult their own tax advisors with respect to the tax consequences of ownership of Series A Bonds with original issue discount, including the treatment of purchasers who do not purchase in the original offering, the allowance of a deduction for any loss on a sale or other disposition, and the treatment of accrued original issue discount on such Series A Bonds under federal alternative minimum taxes. Under the Tax Code, original issue premium is amortized on an annual basis over the term of the Series A Bond (said term being the shorter of the Series A Bond's maturity date or its call date). The amount of original issue premium amortized each year reduces the adjusted basis of the owner of the Series A Bond for purposes of determining taxable gain or loss upon disposition. The amount of original issue premium on a Series A Bond is amortized each year over the term to maturity of the Series A Bond on the basis of a constant interest rate compounded on each interest or principal payment date (with straight-line interpolations between compounding dates). Amortized Series A Bond premium is not deductible for federal income tax purposes. Owners of premium Series A Bonds, including purchasers who do not purchase in the original offering, should consult their own tax advisors with respect to State of California personal income tax and federal income tax consequences of owning such Series A Bonds. California Tax Status. In the further opinion of Bond Counsel, interest on the Bonds is exempt from California personal income taxes. Other Tax Considerations. The opinions expressed by Bond Counsel are based upon existing legislation and regulations as interpreted by relevant judicial and regulatory authorities as of the date of such opinion, and Bond Counsel has expressed no opinion with respect to any proposed legislation or as to the tax treatment of interest on the Bonds, or as to the consequences of owning or receiving interest on the Bonds, as of any future date. Prospective purchasers of the Bonds should consult their own tax advisors regarding any pending or proposed federal or state tax legislation, regulations or litigation, as to which Bond Counsel expresses no opinion. Owners of the Bonds should also be aware that the ownership or disposition of, or the accrual or receipt of interest on, the Bonds may have federal or state tax consequences other than as described 55 August 2, 2018 Regular Board Meeting Agenda Packet- Page 185 of 253 Page 158 of 183 above. Other than as expressly described above, Bond Counsel expresses no opinion regarding other federal or state tax consequences arising with respect to the Bonds, the ownership, sale or disposition of the Bonds, or the amount, accrual or receipt of interest on the Bonds. Form of Opinion Bond Counsel expects to deliver opinions at the time of execution and delivery of the Bonds in substantially the same form set forth in Appendix D. NO LITIGATION There is no action, suit or proceeding known to be pending or threatened, restraining or enjoining the execution of the Indenture or the Bonds or in any way contesting or affecting the validity of the Indenture or the Bonds. The District is not aware of any litigation, pending or threatened, questioning the political existence of the District or contesting the District abilities to pledge revenues or contesting the District's abilities to authorize the execution of the Indenture or the Bonds. RATING S&P Global Ratings, a division of Standard & Poor's Financial Services LLC ("S&P"), has assigned a municipal bond rating of" "to the Bonds. This rating reflects only the views of S&P, and an explanation of the significance of this rating, and any outlook assigned to or associated with this rating, should be obtained from the respective rating agency. Generally, a rating agency bases its rating on the information and materials furnished to it and on investigations, studies and assumptions of its own. The District has provided certain additional information and materials to S&P (some of which does not appear in this Official Statement). There is no assurance that this rating will continue for any given period of time or that this rating not be revised downward or withdrawn entirely by S&P, if in the judgment of S&P, circumstances so warrant. Any such downward revision or withdrawal of this rating may have an adverse effect on the market price or marketability of the Bonds. APPROVAL OF LEGALITY Legal matters incident to the delivery of the Bonds are subject to the approving opinion of Jones Hall,A Professional Law Corporation, San Francisco, California, Bond Counsel. Copies of such opinion will be available at the time of delivery of the Bonds. Jones Hall is also acting as Disclosure Counsel to the District. Certain matters will be passed upon for the District by Kenton Alm, Esq., and for the Underwriter by Kutak Rock, LLP. Payment of the fees and expenses of Bond Counsel, Disclosure Counsel and Underwriter's counsel is contingent upon execution and delivery of the Bonds. 56 August 2, 2018 Regular Board Meeting Agenda Packet- Page 186 of 253 Page 159 of 183 VERIFICATION OF MATHEMATICAL ACCURACY Upon delivery of the Bonds, , , , will deliver a report on the mathematical accuracy of certain computations, contained in schedules provided to the Verification Agent on behalf of the District, relating to the sufficiency of the amounts deposited with the Escrow Agent, together with interest earnings, to pay, when due, the principal, whether at maturity or upon prior redemption, interest and redemption premium requirements of the 2009 Certificates to be defeased and redeemed.

CENTRAL CONTRA COSTA SANITARY DISTRICT By General Manager 57 August 2, 2018 Regular Board Meeting Agenda Packet- Page 187 of 253 Page 160 of 183 APPENDIX A SUMMARY OF THE INDENTURE The following is a brief summary of certain provisions of the Indenture not described elsewhere in this Official Statement. Such summary is not intended to be definitive. Reference is made to the actual Indenture(copies of which are available from the District)for the complete terms thereof. A-1 August 2, 2018 Regular Board Meeting Agenda Packet- Page 188 of 253 Page 161 of 183 APPENDIX B CONTRA COSTA COUNTY GENERAL INFORMATION The following information relating to the District and Contra Costa County, and the State of California is supplied solely for the purposes of information. The District's obligation to pay the Bonds and any other amounts coming due and payable under the Indenture are a special obligation of the District limited solely to the Tax Revenues and the Net Revenues; the Bonds are not an obligation of the County, the State or any political subdivisions other than the District. THE COUNTY General Contra Costa County was incorporated in 1850 as one of the original 27 counties of the State, with the City of Martinez as the County Seat. It is one of the nine counties in the San Francisco- Oakland Bay Area. The County covers about 733 square miles and extends from the northeastern shore of San Francisco Bay easterly about 50 miles to San Joaquin County. Contra Costa is bordered on the south and west by Alameda County and on the north by Suisun and San Pablo Bays. The western and northern shorelines are highly industrialized, while the interior sections are suburban/residential, commercial and light industrial. A large part of the interior of the County is served by the Bay Area Rapid Transit District ("BART"), a situation that has encouraged the expansion of both residential and commercial development. In addition, economic development along the Interstate 680 corridor in the County has been so substantial that three cities- Concord,Walnut Creek and San Ramon- placed among the top four cities accounting for the greatest percentage increases in jobs in the entire Bay Area from 1985 through 1990. County Government The County has a general law form of government. A five-member Board of Supervisors, each of whom is elected to a four-year term, serves as the County's legislative body. Also elected are the County Assessor, Auditor-controller, Clerk-Recorder, District Attorney-Public Administrator, Sheriff- Coroner and Treasurer-Tax Collector. A County Administrative Officer appointed by the Board of Supervisors runs the day-to-day business of the County. B-1 August 2, 2018 Regular Board Meeting Agenda Packet- Page 189 of 253 Page 162 of 183 Population Contra Costa County is the ninth most populous county in California, with its population reaching approximately 1,149,363 as of January 1, 2018.

Accordingly, no representations can be made concerning these matters and neither the DTC Participants nor the Beneficial Owners should rely on the foregoing information with respect to such matters, but should instead confirm the same with DTC or the DTC Participants, as the case may be. Neither the issuer of the Bonds (the "Issuer) nor the trustee, fiscal agent or paying agent appointed with respect to the Bonds (the "Agent') take any responsibility for the information contained in this Appendix. No assurances can be given that DTC, DTC Participants or Indirect Participants will distribute to the Beneficial Owners(a)payments of interest, principal or premium, if any, with respect to the Bonds, (b) certificates representing ownership interest in or other confirmation or ownership interest in the Bonds, or(c) redemption or other notices sent to DTC or Cede & Co., its nominee, as the registered owner of the Bonds, or that they will so do on a timely basis, or that DTC, DTC Participants or DTC Indirect Participants will act in the manner described in this Appendix. The current"Rules"applicable to DTC are on file with the Securities and Exchange Commission and the current "Procedures"of DTC to be followed in dealing with DTC Participants are on file with DTC. 1. The Depository Trust Company ("DTC"), New York, NY, will act as securities depository for the bonds (the "Bonds"). The Bonds will be issued as fully- registered securities registered in the name of Cede & Co. (DTC's partnership nominee) or such other name as may be requested by an authorized representative of DTC. One fully-registered certificate will be issued for the Bonds, in the aggregate principal amount of such issue, and will be deposited with DTC. If, however, the aggregate principal amount of any issue exceeds $500 million, one certificate will be issued with respect to each $500 million of principal amount and an additional certificate will be issued with respect to any remaining principal amount of such issue. 2. DTC, the world's largest securities depository, is a limited-purpose trust company organized under the New York Banking Law, a "banking organization"within the meaning of the New York Banking Law, a member of the Federal Reserve System, a "clearing corporation" within the meaning of the New York Uniform Commercial Code, and a "clearing agency" registered pursuant to the provisions of Section 17A of the Securities Exchange Act of 1934. DTC holds and provides asset servicing for over 3.5 million issues of U.S. and non-U.S. equity issues, corporate and municipal debt issues, and money market instruments (from over 100 countries) that DTC's participants ("Direct Participants") deposit with DTC. DTC also facilitates the post-trade settlement among Direct Participants of sales and other securities transactions in deposited securities, through electronic computerized book-entry transfers and pledges between Direct Participants' accounts. This eliminates the need for physical movement of securities certificates. Direct Participants include both U.S. and non-U.S. securities brokers and dealers, banks, trust companies, clearing corporations, and certain other organizations. DTC is a wholly-owned subsidiary of The Depository Trust & Clearing Corporation ("DTCC"). DTCC is the holding company for DTC, National Securities Clearing Corporation and Fixed Income Clearing Corporation, all of which are registered clearing agencies. DTCC is owned by the users of its regulated subsidiaries.Access to the DTC system is also available to others such as both U.S. and non-U.S. securities brokers and dealers, banks, trust companies, F-1 August 2, 2018 Regular Board Meeting Agenda Packet- Page 206 of 253 Page 179 of 183 and clearing corporations that clear through or maintain a custodial relationship with a Direct Participant, either directly or indirectly("Indirect Participants"). DTC has a Standard &Poor's rating of AA+. The DTC Rules applicable to its Participants are on file with the Securities and Exchange Commission. More information about DTC can be found at www.dtcc.com. The information contained on this Internet site is not incorporated herein by reference. 3. Purchases of Bonds under the DTC system must be made by or through Direct Participants, which will receive a credit for the Bonds on DTC's records. The ownership interest of each actual purchaser of each Bond ("Beneficial Owner") is in turn to be recorded on the Direct and Indirect Participants' records. Beneficial Owners will not receive written confirmation from DTC of their purchase. Beneficial Owners are, however, expected to receive written confirmations providing details of the transaction, as well as periodic statements of their holdings, from the Direct or Indirect Participant through which the Beneficial Owner entered into the transaction. Transfers of ownership interests in the Bonds are to be accomplished by entries made on the books of Direct and Indirect Participants acting on behalf of Beneficial Owners. Beneficial Owners will not receive certificates representing their ownership interests in Bonds, except in the event that use of the book- entry system for the Bonds is discontinued. 4. To facilitate subsequent transfers, all Bonds deposited by Direct Participants with DTC are registered in the name of DTC's partnership nominee, Cede & Co. or such other name as may be requested by an authorized representative of DTC. The deposit of Bonds with DTC and their registration in the name of Cede &Co. or such other nominee do not effect any change in beneficial ownership. DTC has no knowledge of the actual Beneficial Owners of the Bonds; DTC's records reflect only the identity of the Direct Participants to whose accounts such Bonds are credited, which may or may not be the Beneficial Owners. The Direct and Indirect Participants will remain responsible for keeping account of their holdings on behalf of their customers. 5. Conveyance of notices and other communications by DTC to Direct Participants, by Direct Participants to Indirect Participants, and by Direct Participants and Indirect Participants to Beneficial Owners will be governed by arrangements among them, subject to any statutory or regulatory requirements as may be in effect from time to time. Beneficial Owners of Bonds may wish to take certain steps to augment transmission to them of notices of significant events with respect to the Bonds, such as redemptions, tenders, defaults, and proposed amendments to the security documents. For example, Beneficial Owners of Bonds may wish to ascertain that the nominee holding the Bonds for their benefit has agreed to obtain and transmit notices to Beneficial Owners, in the alternative, Beneficial Owners may wish to provide their names and addresses to the registrar and request that copies of the notices be provided directly to them. 6. Redemption notices shall be sent to DTC. If less than all of the Bonds within an issue are being redeemed, DTC's practice is to determine by lot the amount of the interest of each Direct Participant in such issue to be redeemed. 7. Neither DTC nor Cede & Co. (nor such other DTC nominee) will consent or vote with respect to the Bonds unless authorized by a Direct Participant in accordance with DTC's Procedures. Under its usual procedures, DTC mails an Omnibus Proxy to Issuer as soon as possible after the record date. The Omnibus Proxy assigns Cede&Co.'s consenting or voting rights to those Direct Participants to whose accounts the Bonds are credited on the record date (identified in a listing attached to the Omnibus Proxy). 8. Redemption proceeds, distributions, and interest payments on the Bonds will be made to Cede & Co., or such other nominee as may be requested by an authorized representative of DTC. DTC's practice is to credit Direct Participants' accounts, upon DTC's receipt of funds and corresponding detail information from Issuer or Agent on payable date in accordance with their F-2 August 2, 2018 Regular Board Meeting Agenda Packet- Page 207 of 253 Page 180 of 183 respective holdings shown on DTC's records. Payments by Participants to Beneficial Owners will be governed by standing instructions and customary practices, as is the case with securities held for the accounts of customers in bearer form or registered in "street name," and will be the responsibility of such Participant and not of DTC nor its nominee, Agent, or Issuer, subject to any statutory or regulatory requirements as may be in effect from time to time. Payment of redemption proceeds, distributions, and dividend payments to Cede & Co. (or such other nominee as may be requested by an authorized representative of DTC) is the responsibility of Issuer or Agent, disbursement of such payments to Direct Participants will be the responsibility of DTC, and disbursement of such payments to the Beneficial Owners will be the responsibility of Direct and Indirect Participants. 9. DTC may discontinue providing its services as securities depository with respect to the Bonds at any time by giving reasonable notice to Issuer or Agent. Under such circumstances, in the event that a successor securities depository is not obtained, security Bonds are required to be printed and delivered. 10. Issuer may decide to discontinue use of the system of book-entry-only transfers through DTC (or a successor securities depository). In that event, security certificates will be printed and delivered to DTC. 11. The information in this section concerning DTC and DTC's book-entry system has been obtained from sources that Issuer believes to be reliable, but Issuer takes no responsibility for the accuracy thereof.
