CENTRAL SAN BOARD OF DIRECTORS POSITION PAPER MEETING DATE: JUNE 3, 2021 SUBJECT: DISCUSS ISSUES RELATED TO PROPOSED 2021 DEBT TRANSACTION AND ADOPT RESOLUTION NO. 2021-028 AUTHORIZING THE EXECUTION, DELIVERYAND SALE OF WASTEWATER CERTIFICATES OF PARTICIPATION IN THE MAXIMUM PRI NCI PAL AMOUNT OF $65,000,000 TO FINANCE CAPITAL IMPROVEMENT PROJECTS OF THE DISTRICT SUBMITTED BY: INITIATING DEPARTMENT: KEVIN MIZUNO, FINANCE MANAGER ADMINISTRATION-FINANCE PHILIP LEIBER, DIRECTOR OF FINANCE AND ADMINISTRATION Roger S. Bailey General Manager ISSUE Board approval of a proposed 2021 financing transaction for up to $65 million through certificates of participation is requested. Additional topics for context and further consideration include an update on interest rates, the CCCERA pay-down amount; market timing considerations including impact of potentially higher inflation on market returns; and the flow of funds to effectuate the transaction objectives. BACKGROUND This proposed financing transaction has been discussed at several Committee and Board meetings held in March, April, and May. Meetings in March focused on the potential of achieving interest savings through the issuance of debt in 2021 to finance a portion of the planned Capital I mprovement Budget(s) (Cl B). I n April and May, a resolution was discussed and adopted regarding the selection of a financing team and the proposed method of issuance of the debt (a competitive offering). At the May 25 Finance Committee meeting, further topics related to the issuance were discussed, which are presented in this position paper. During May, the financing team has: • Completed the draft official statement describing Central San and the issuance to investors. • Scheduled a meeting with a credit rating agency for Thursday, May 27. June 3, 2021 Regular Board Meeting Agenda Packet- Page 426 of 646 Page 2 of 186 • Completed drafts of other key debt related documents including District Resolution, Financing Authority Resolution, Installment Sale Agreement, Trust Agreement, Notice of Sale, Preliminary Official Statement. Several topics were discussed with the Finance Committee on May 25, including: 1. Update on Interest Rates: Interest rates are generally holding steady in recent weeks. National average rates for 10-year AAA rated tax-exempt debt were as shown in the table below. Because of this, a key rationale for moving forward with the transaction remains valid--taking advantage of low interest rates to borrow for the capital program, and to free up funds to pay down the CCCERA unfunded actuarially accrued liability(UAAL), which until paid off, accrues interest at 7%. Average for December 2020 April 12, 2021 May 11, 2021 May 18, 2021 0.71% 1.03% 0.95% 1.00% 2. CCCERA Paydown Amount: Discussion by the Committee was held on the topic of whether to consider adjusting the debt issuance amount or the CCCERA UAAL paydown amount (as noted below in Alternatives)to reduce the potential risk of "superfunding", whereby the pension funded ratio exceeds 100%. The Committee did not reach a final decision on whether to pay 100% of the CCCERA UAAL, or to pay a somewhat lesser amount and deposit the balance in the Pension Prefunding Trust. The Committee did recommended proceeding with the COP transaction with further discussion of the paydown amount in June (after staff noted can be discussed until late June). 3. "Market timing" considerations: With concerns about inflation increasing, and the impact this could have on equity and debt market returns, a question was raised as to whether it is prudent to pay down the UAAL in full at this time. The histogram of potential transaction outcomes prepared by PFM captured the range of adverse to favorable outcomes based on sampling historical returns over the past 20 years. Prognosticating a particular return outcome (good or bad) in the coming years is certainly speculative. That said, as the PFM analysis histogram indicated, there was an approximately 80% likelihood of a favorable outcome based on market return experience over the past 20 years (which averaged 7.7%). An updated analysis conducted by PFM now shows an 87% likelihood for a favorable outcome, based on a reduction in the interest rate cushion as the bond sale date gets closer, as well as less conservative assumptions about CCCERA amortizations now that a specific schedule of amortizations has been provided by CCCERA. That said, if prospective returns, on average, differ significantly from historic returns, that decreases the likelihood of a favorable outcome. Specifically, if inflation or other factors contributed to future market returns rates averaging 5% (rather than 7.7%), the probability of success drops somewhat, but remains a relatively high 75%. PFM's Asset Management group has also stated their position is that "inflation is on the rise but not alarmingly so and any spike above 2.0%-2.5% will be temporary". Other notable prognosticators have said essentially the same. One other factor for consideration is that in an inflationary environment, there are advantages to being a borrower, as dollars borrowed today are paid back with less valuable dollars later. Normally interest rates would rise to reflect the risk to bond buyers of this, but thus far, interest rates for a high quality tax-exempt borrower like Central San remain very attractive. 4. Flow of funds: Staff has been working to specify the sources and timing of the CCCERA payoff amount. The following constraints must be considered: a. The CCCERA UAAL paydown must be completed prior to July 1, 2021, in order for UAAL amortization payments to CCCERA to be avoided in Fiscal Year (FY) 2021-22. b. Bond monies can only be used to reimburse or pay for capital expenditures. This includes FY 2020-21 capital expenditures incurred after March 7 (60 days prior to the Board's adoption of the Reimbursement Resolution), and FY 2021-22 capital expenditures incurred over the course of the next fiscal year. June 3, 2021 Regular Board Meeting Agenda Packet- Page 427 of 646 Page 3 of 186 In consideration of these complexities, some inter-fund movements and borrowings will be necessary. The following table provides an outline of the currently planned approach using the latest estimates: Line Source FY N Fund Amount (in millions) $12.5 from March &April plus at least 1 Reimbursement of Capital Expenditures from FY 20-21 Sc $12.1 from May 2020-21 post 3/6/2021 & June 2021 (reimbursements for spending amounts not yet determinable) Sewer Service Charge for FY 2021-22 SSC arrives in December 2021 &April 2022, so an inter-fund loan in June 2021 to the Running Expense fund will be necessary until it is available. There is 2 estimated to be approximately$28.4 million above the 21-22 Sc $34.1 policy required minimum reserve level in the Sewer Construction fund at June 30, 2021, PLUS the amount of the unspent carryforward from FY 2020-21. Accordingly, there will be adequate funding available to facilitate a loan, while not dropping below policy required levels. Rate Stabilization Funds from Planned transfer in FY 2021-22 (These funds will be in the Running Expense fund as 3 of June 30, 2021. Use in this transaction not presently 21-22 R/E $0.0 specified. One alternative would be to move these funds to the Pension Prefunding Trust, as a replenishment for when the Pension Prefunding Trust is drawn down as noted below) Trust 4 Pension Pre-funding Trust 20-21 balance at $12.0 3/31/2021 5 Total for UAAL Paydown 20-21 Additionally, staff are still assessing the impact that this financing transaction has on the annual Concord wastewater treatment bill. As this is at its core a debt refinancing transaction, it should provide the City of Concord a proportionate share of the savings through the substitution of prospective high interest and volatile pension UAAL payments made to CCCERAwith low and fixed interest debt service payments. June 3, 2021 Regular Board Meeting Agenda Packet- Page 428 of 646 Page 4 of 186 5. Review of Transaction Related Documents The Finance Committee reviewed several key transaction documents including: 1. District Resolution 2. Installment Sale Agreement 3. Trust Agreement 4. Notice of Sale 5. Draft Preliminary Official Statement The Committee provided feedback on the Preliminary Official Statement and Installment Sale Agreement, and these edits have been reflected in the documents now attached to this position paper. These documents are now in essentially final form, but there could be minor edits until final execution. Board approval of the District Resolution will provide for the acceptance of the remaining documents, and is being recommended at this time. It should be noted that the District Resolution and Issuance Resolution make reference to a maximum issuance amount of$65,000,000 and a maximum true interest cost of 2.00%. These are both substantially above anticipated amounts as of May 27, 2021, but are higher to allow for a cushion to reflect changes between the present date and the bond pricing in mid-June. ALTERNATIVES/CONSIDERATIONS Primary alternatives for consideration include: 1. Whether to proceed with a debt issuance transaction or not. Proceeding would allow for the pension UAAL paydown that has been described in this and proceeding presentations, or for other purposes (omitted here for brevity). The transaction has the potential to provide for significant interest cost savings over the next decade, and allow for a significant reduction in the Operations & Maintenance budget due to elimination of UAAL payments (to be replaced in substantial part by debt service costs). Staff and the Finance Committee have recommended moving forward with the debt issuance transaction. 2. Whether to send CCCERA an amount sufficient to fully retire the UAAL (bringing the funded ratio to 100%), or whether to instead send CCCERA a lesser amount. This could be accomplished by either borrowing a lesser amount, or borrowing the recommended principal amount (targeted at $59 million and not to exceed $65 million), and depositing a portion of the funds that would have otherwise gone to CCCERA into the Pension Pre-Funding Trust. For example, sufficient funds could be sent to CCCERAto provide for a 97% funding ratio, and the balance of funds could be kept in the Pension Prefunding Trust. This was discussed briefly at the Finance Committee on April 27, 2021, and again on May 25, 2021; no final recommendation has been made, and can be discussed further in June 2021. Advantages to this alternative would be: a. Greater flexibility of funds in the Pension Prefunding Trust as they could be used to pay normal/ongoing Pension costs. b. Reducing the risk of"super-funding". c. Potential further diversification of investment returns due to different investment choices than those made by CCCERA's investment managers. Disadvantages include: a. CCCERA does not recognize the funds held in the Pension Prefunding Trust, which consequently results in those assets being excluded from Central San's funded position in annually actuarial reports published by CCCERA. They will continue to charge Central San amortization of any UAAL layers that exist per their actuarial records. However, funds in the Pension Prefunding June 3, 2021 Regular Board Meeting Agenda Packet- Page 429 of 646 Page 5 of 186 Trust could be drawn down/used to pay those ongoing UAAL amortization charges or even be eligible to reimburse the normal cost component of pension contributions in the future. b. CCCERA's investment classes include categories beyond traded debt and equity funds, potentially providing for higher return opportunities beyond those available in the Pension Prefunding Trust. FINANCIAL IMPACTS An assessment of the potential overall net savings (or cost) of the transaction was discussed at the April 27 Finance Committee meeting, and presented to the Board at the May 6 meeting. As the transaction closing date approaches, PFM updated their analysis by removing an interest rate "cushion" using amortization information received from CCCERA, and found that the likelihood of at least some positive cost savings has risen to 87%, with the most likely cost savings at about$15 million over the maturity of the debt. Actual savings will depend on investment returns by CCCERA (or in the Pension Prefunding Trust if some funds are kept their rather than sent to CCCERA). The following disclosure is provided, as required by the State of California, to the Board of any agency contemplating a debt issuance. It should be noted that the amounts provided are per PFM's debt calculations as of May 27, 2021, with the interest rate specified inclusive of a 0.25% buffer to allow for movements from the current date until issuance date. In accordance with Government Code Section 5852.1, the following information has been obtained and disclosed to the Board prior to the authorization of the debt: (i) the estimated true interest cost of the debt(being the rate necessary to discount the amounts payable on the respective principal and interest payment dates to the purchase price received for the debt) is 1.125%, (ii) the estimated finance charge of the debt(being the sum of all fees and charges paid to third parties) is $739,450, (iii) the estimated proceeds of the debt expected to be received by the District, net of proceeds for finance charges in (ii) above to paid from the principal amount of the debt is $58,001,212, and(iv) the estimated total payment amount of the debt(being the sum of debt service plus finance to be paid to final maturity, plus any financing costs not paid from proceeds of the debt) is $60,053,047. This information is based on good-faith estimates provided by the District's financial advisor. COMMITTEE RECOMMENDATION The Finance Committee reviewed this matter at its meeting on May 25, 2021. The Committee recommended Board approval of the debt issuance, and continued consideration into June the issue of either sending the full UAAL payoff amount to CCCERA, or a lesser amount with the balance to be held in the Pension Prefunding Trust. RECOMMENDED BOARD ACTION Staff recommends adoption the proposed resolution authorizing the execution, delivery and sale of wastewater certificates of participation in the maximum principal amount of$65,000,000 to finance capital improvement projects of the District.

(iii) No Preference or Priority. The District shall pay the Installment Payments and the principal of and interest on any Parity Obligations from Net Revenues without preference or priority among the Installment Payments and Parity Obligations.

Notwithstanding the foregoing provisions of this subsection (a), however, if, at any time after the principal components of the unpaid Installment Payments have 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 deposits with the Trustee -15- June 3, 2021 Regular Board Meeting Agenda Packet- Page 452 of 646 Page 28 of 186 a sum sufficient to pay all principal components of the Installment Payments coming due prior to such declaration and all matured interest components(if any)of the Installment Payments,with interest on such overdue principal and interest components calculated at the Overdue Rate, and the reasonable fees and expenses of the Trustee (including any fees and expenses of its attorneys), and any and all other defaults known to the Trustee (other than in the payment of the principal and interest components of the Installment Payments due and payable solely by reason of such declaration) have been made good, then, and in every such case, the Trustee shall rescind and annul such declaration and its consequences. However, no such rescission and annulment extends to or affects any subsequent default, or impairs or exhausts any right or power consequent thereon. As provided in Section 6.6, the Trustee is required to exercise the remedies provided herein in accordance with the Indenture. (b) Action at Law or in Equity. Take whatever action at law or in equity may appear necessary or desirable to collect the Installment Payments then due or thereafter to become due during the Term of this Agreement, or enforce performance and observance of any obligation, agreement or covenant of the District under this Agreement. (c) Appointment of Receiver. As a matter of right, in connection with the filing of a suit or other commencement of judicial proceedings to enforce the rights of the Trustee and the Certificate Owners hereunder, cause the appointment of a receiver or receivers of the Gross Revenues and other amounts pledged hereunder, with such powers as the court making such appointment shall confer.

The District is proceeding to finance the acquisition and construction of certain improvements to the Wastewater System as more particularly described in Appendix A to the hereinafter defined Installment Sale Agreement (the "Project") between the District and the Authority, and in order to provide such financing the Authority has proposed to acquire and construct the Project and sell the completed Project to the District as provided therein. 3. The Authority has been formed for the purpose of providing such financial assistance to the District. 4. Under the Installment Sale Agreement, the District has agreed to pay installments of the purchase price of such improvements in semiannual installments (the "Installment Payments"), to be payable from and secured by a pledge of and lien on the net revenues received by the District from the Wastewater System and from the revenues derived by the District from ad valorem property taxes levied in the District. 5. For the purpose of obtaining the moneys required to provide financing to the District in accordance with the terms of the Installment Sale Agreement, the Authority, the District and the Trustee have agreed to enter into this Indenture under which the Authority assigns and transfers certain of its rights under the Installment Sale Agreement to the Trustee, and the Trustee agrees to execute and deliver the Certificates, evidencing direct, undivided fractional interests in the Installment Payments, the proceeds of which will be applied to finance the Project as provided herein and in the Installment Sale Agreement. AGREEMENT : In consideration of the premises and the material covenants contained herein, the District, the Authority and the Trustee hereby agree as follows: June 3, 2021 Regular Board Meeting Agenda Packet- Page 464 of 646 Page 40 of 186 ARTICLE I DEFINITIONS ; RULES OF INTERPRETATION SECTION 1.01. Definitions. Unless the context clearly otherwise requires or unless otherwise defined herein, the capitalized terms used in this Indenture have the respective meanings given them in Appendix A attached to this Indenture. SECTION 1.02. Authorization. Each of the parties hereby represents and warrants that it has full legal authority and is duly empowered to enter into this Indenture, and has taken all actions necessary to authorize the execution hereof by the officers and persons signing it. SECTION 1.03. Interpretation. (a) Unless the context otherwise indicates, words expressed in the singular include the plural and vice versa and the use of the neuter, masculine, or feminine gender is for convenience only and includes the neuter, masculine or feminine gender, as appropriate. (b) Headings of articles and sections herein and the table of contents hereof are solely for convenience of reference, do not constitute a part hereof and do not affect the meaning, construction or effect hereof. (c) All references herein to "Articles", "Sections" and other subdivisions are to the corresponding Articles, Sections or subdivisions of this Indenture; the words "herein," "hereof," "hereby," "hereunder" and other words of similar import refer to this Indenture as a whole and not to any particular Article, Section or subdivision hereof. ARTICLE II THE CERTIFICATES OF PARTICIPATION SECTION 2.01. Authorization. The Trustee is hereby authorized and directed upon written request from the Authority to register, execute and deliver, to the Original Purchaser, Certificates in an aggregate principal amount of$ , which constitute certificates of participation representing the direct, undivided fractional ownership interests of the Owners thereof in the Installment Payments. SECTION 2.02. Date. Each Certificate shall be dated as of the Closing Date, and interest represented thereby is payable from the Interest Payment Date next preceding the date of execution thereof, unless: (a) it is executed after a Record Date and on or before the following Interest Payment Date, in which event interest represented thereby is payable from such Interest Payment Date; or -2- June 3, 2021 Regular Board Meeting Agenda Packet- Page 465 of 646 Page 41 of 186 (b) it is executed on or before the first Record Date, in which event interest represented thereby shall be payable from the Closing Date; or (c) interest represented by such Certificate is in default as of the date of execution of such Certificate, in which event interest represented thereby is payable from the Interest Payment Date to which interest represented thereby has previously been paid or made available for payment. SECTION 2.03. Terms of Certificates. Principal represented by the Certificates is payable on September 1 in each of the respective years and in the respective amounts, and interest represented thereby is computed at the respective rates, as follows: Maturity Date Principal Interest Maturity Date Principal Interest (September 1) Amount Rate (September 1) Amount Rate SECTION 2.04. Fully Registered Form; Interest. The Certificates will be delivered in the form of fully registered Certificates without coupons in the authorized denominations of $5,000 or any integral multiple thereof, except that no Certificate shall represent principal payable in more than one year. The Certificates will be assigned such alphabetical and numerical designation as the Trustee deems appropriate. Interest represented by the Certificates is payable on each Interest Payment Date to and including the date of maturity or prepayment, whichever is earlier, as provided in Section 2.09. Said interest represents the portion of the Installment Payments designated as interest and coming due on each of the respective Interest Payment Dates. The share of the portion of Installment Payments designated as interest with respect to any Certificate is computed by multiplying the portion of Installment Payments designated as principal represented by such Certificate by the rate of interest represented by such Certificate (on the basis of a 360-day year of twelve 30-day months). SECTION 2.05. Book Entry System. (a) Original Delivery. The Certificates shall be initially delivered in the form of a separate single fully registered Certificate (which may be typewritten) for each maturity of the Certificates. Upon initial delivery, the ownership of each such Certificate shall be registered on the Registration Books in the name of the Nominee. Except as provided in subsection (c), the ownership of all of the Outstanding Certificates shall be registered in the name of the Nominee on the Registration Books. -3- June 3, 2021 Regular Board Meeting Agenda Packet- Page 466 of 646 Page 42 of 186 With respect to Certificates the ownership of which is registered in the name of the Nominee, the District and the Trustee have no responsibility or obligation to any Depository System Participant or to any person on behalf of which the District holds an interest in the Certificates. Without limiting the generality of the immediately preceding sentence, the District and the Trustee have 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 Certificates, (ii)the delivery to any Depository System Participant or any other person, other than a Certificate Owner as shown in the Registration Books, of any notice with respect to the Certificates, including any notice of prepayment, (iii)the selection by the Depository of the beneficial interests in the Certificates to be redeemed in the event the District elects to redeem the Certificates in part, (iv) the payment to any Depository System Participant or any other person, other than a Certificate Owner as shown in the Registration Books, of any amount with respect to principal, premium, if any, or interest represented by the Certificates or(v) any consent given or other action taken by the Depository as Owner of the Certificates. The District and the Trustee may treat and consider the person in whose name each Certificate is registered as the absolute owner of such Certificate for the purpose of payment of principal, premium, if any, and interest represented by such Certificate, for the purpose of giving notices of prepayment and other matters with respect to such Certificate, for the purpose of registering transfers of ownership of such Certificate, and for all other purposes whatsoever. The Trustee shall pay the principal, interest and premium, if any, represented by the Certificates 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, interest and premium, if any, represented by the Certificates to the extent of the sum or sums so paid. No person other than a Certificate Owner shall receive a Certificate 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 Nominee of written notice to the effect that the Depository has determined to substitute a new Nominee in its place, 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 Certificates for the Depository's book-entry system, the District and the Trustee shall execute and deliver to such Depository a letter representing such matters as shall be necessary to so qualify the Certificates. The execution and delivery of such letter in no way limits the provisions of subsection (a) above or otherwise imposes upon the District or the Trustee any obligation whatsoever with respect to persons having interests in the Certificates other than the Certificate Owners. 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 Certificates for the Depository's book-entry program. (c) Transfers Outside Book-Entry System. If either(i)the Depository determines not to continue to act as Depository for the Certificates, 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 execution and delivery of replacement Certificates by providing the Trustee with a list showing the interests of the Depository System Participants in the Certificates, and by surrendering the Certificates, registered in the name of the Nominee, to the Trustee on or before the date such replacement Certificates -4- June 3, 2021 Regular Board Meeting Agenda Packet- Page 467 of 646 Page 43 of 186 are to be executed and delivered. The Depository, by accepting delivery of the Certificates, 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 Certificates 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 Certificates 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 Certificates that they be able to obtain certificated Certificates, the District may notify the Depository System Participants of the availability of such certificated Certificates through the Depository. In such event, the Trustee will execute, transfer and exchange Certificates 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 (y) to make available one or more separate certificates evidencing the Certificates to any Depository System Participant having Certificates credited to its account with the Depository, or (z) to arrange for another Securities Depository to maintain custody of a single certificate evidencing such Certificates, all at the District's expense. (d) Payments to the Nominee. Notwithstanding any other provision of this Indenture to the contrary, so long as any Certificate is registered in the name of the Nominee, all payments with respect to principal, interest and premium, if any, represented by such Certificate and all notices with respect to such Certificate 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 2.06. Form and Execution of Certificates. The Certificates shall be substantially in the form set forth in Appendix B attached hereto and by this reference incorporated herein. An authorized signatory of the Trustee shall execute the Certificates in the name and on behalf of the Trustee. If any person whose signature appears on any Certificate ceases to be an authorized signatory before the date of delivery of said Certificate, such signature shall nevertheless be as effective as if such person had remained an authorized signatory until such date. SECTION 2.07. Transfer and Exchange. (a) Transfer of Certificates. The registration of any Certificate 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, upon surrender of such Certificate for cancellation at the Corporate Trust Office of the Trustee, accompanied by delivery of a written instrument of transfer in a form acceptable to the Trustee, duly executed. Whenever any Certificate or Certificates shall be surrendered for registration of transfer, the Trustee shall execute and deliver a new Certificate or Certificates representing the same maturity, interest rate and aggregate principal amount, in any authorized denominations. The District shall pay all costs of the Trustee incurred in connection with any such transfer, except that the Trustee may require the payment by the Certificate Owner of any tax or other governmental charge required to be paid with respect to such transfer. -5- June 3, 2021 Regular Board Meeting Agenda Packet- Page 468 of 646 Page 44 of 186 (b) Exchange of Certificates. Certificates may be exchanged at the Corporate Trust Office of the Trustee, for a like aggregate principal amount of Certificates representing other authorized denominations of the same interest rate and maturity. The District shall pay all costs of the Trustee incurred in connection with any such exchange, except that the Trustee may require the payment by the Certificate Owner requesting such exchange of any tax or other governmental charge required to be paid with respect to such exchange. (c) Limitations on Transfer or Exchange. The Trustee may refuse to transfer or exchange either (i) any Certificate during the period established by the Trustee for the selection of Certificates for prepayment, or (ii) the portion of any Certificate which the Trustee has selected for prepayment under the provisions of Section 4.02. SECTION 2.08. Certificates Mutilated, Lost, Destroyed or Stolen. If any Certificate is mutilated, the Trustee, at the expense of the Owner of such Certificate, shall execute and deliver a new Certificate of like principal amount, interest rate and maturity in replacement for the Certificate so mutilated, but only upon surrender to the Trustee of the Certificate so mutilated. Every mutilated Certificate so surrendered to the Trustee shall be cancelled by it and destroyed by the Trustee, who shall, upon request of the District, deliver a certificate of destruction to the District. If any Certificate shall be lost, destroyed or stolen, evidence of such loss, destruction or theft must be submitted to the Trustee, and, if such evidence is satisfactory to the Trustee and the District and, if an indemnity satisfactory to the Trustee and the District shall be given, the Trustee, at the expense of the Certificate Owner, shall execute and deliver a new Certificate of like principal amount, interest rate and maturity and numbered as the Trustee shall determine in lieu of and in replacement for the Certificate so lost, destroyed or stolen. The Trustee may require payment of an appropriate fee for each replacement Certificate delivered under this Section 2.08 and of the expenses which may be incurred by the Trustee in carrying out the duties under this Section 2.08. Any Certificate executed and delivered under the provisions of this Section 2.08 in lieu of any Certificate alleged to be lost, destroyed or stolen shall be equally entitled to the benefits of this Indenture with all other Certificates secured by this Indenture. The Trustee is not required to treat both the original Certificate and any replacement Certificate as being Outstanding for the purpose of determining the principal amount of Certificates which may be executed and delivered hereunder or for the purpose of determining any percentage of Certificates Outstanding hereunder, but both the original and replacement Certificate shall be treated as one and the same.

The District has the right to rescind any notice of prepayment of the Certificates under Section 4.01 by written notice to the Trustee on or prior to the dated fixed for prepayment. Any notice of prepayment shall be cancelled and annulled if for any reason funds will not be or are not available on the date fixed for prepayment for the payment in full of the Certificates then called for prepayment, and such cancellation shall not constitute an Event of Default.

If, on said date of prepayment, moneys for the prepayment of all the Certificates to be prepaid, together with interest represented thereby to said date of prepayment, shall be held by the Trustee so as to be available therefor on such date of prepayment, then, from and after said date of prepayment, interest represented by the Certificates shall cease to accrue and be payable.

Each Certificate will be dated the date of its execution and delivery, and interest represented by the Certificates is payable from the Interest Payment Date next preceding the date of execution, unless: (a) it is executed after a Record Date (the close of business on the 15th day of the month preceding each Interest Payment Date, whether or not such 15th day is a Business Day) and on or before the following Interest Payment Date, in which event interest represented thereby is payable from the Interest Payment Date; or (b) it is executed on or before the first Record Date, in which event interest represented thereby will be payable from the date of execution and delivery of the Certificates; or (c) interest represented by such Certificate is in default as of the date of execution of such Certificate, in which event interest represented by the Certificate is payable from the Interest Payment Date to which interest has previously been paid or made available for payment. The Certificates will be executed and delivered in book-entry only form without coupons, in denominations of $5,000 each or any integral multiple thereof. Principal and premium, if any, evidenced and represented by the Certificates will be payable by the Trustee to DTC, which will in turn remit such principal and interest to its participants for subsequent disbursement to Owners. Prepayment* [No Optional Prepayment. Except as described below with respect to Net Proceeds of insurance or condemnation awards, the Certificates are not subject to prepayment at the option of the District prior to maturity.] Extraordinary Prepayment from Net Proceeds. The Certificates shall be subject to extraordinary prepayment prior to their respective stated maturities, as a whole or in part on any date, as determined by the District, from Net Proceeds, upon the terms and conditions of, and as provided for in the Installment Sale Agreement, as applicable, at a prepayment price equal to the principal amount of the Certificates to be prepaid, plus accrued interest thereon to the date fixed for prepayment, without premium. Selection of Certificates for Prepayment. Whenever provision is made for the prepayment of Certificates and less than all Outstanding Certificates of any one maturity are called for prepayment, the Trustee will select Certificates for prepayment within such maturity by lot in any manner deemed fair by the Trustee. For this purpose, Certificates will be deemed to be composed *Preliminary;subject to change. 5 June 3, 2021 Regular Board Meeting Agenda Packet- Page 530 of 646 Page 106 of 186 of $5,000 portions, and any such portion may be separately prepaid. The Trustee will promptly notify the District and the Authority in writing of the Certificates or portions thereof selected for prepayment. The selection by the Trustee of any Certificates for prepayment will be final and conclusive. Notice of Prepayment When prepayment is authorized or required under the Indenture, the Trustee shall give notice of the prepayment of the Certificates on behalf and at the expense of the District. Such notice shall state the prepayment date and prepayment price and, if less than all of the then Outstanding Certificates of any maturity are to be called for prepayment, shall designate the numbers of the Certificates to be prepaid by giving the individual number of each Certificate or by stating that all Certificates between two stated numbers, both inclusive, have been called for prepayment or by stating that all of the Certificates of one or more maturities have been called for prepayment, and shall require that such Certificates be surrendered on the designated prepayment date at the Corporate Trust Office of the Trustee for prepayment at said prepayment price. Such notice shall further state that on the specified date there shall come due and payable upon each Certificate, the principal and premium, if any, together with interest accrued to said date, and that from and after such date interest with respect thereto shall cease to accrue and be payable. Notice of such prepayment shall be mailed by first class mail with postage prepaid, to the Securities Depository, and the Owners of Certificates designated for prepayment at their respective addresses appearing on the Registration Books. Such notice shall be mailed at least 20 days but not more than 60 days prior to the prepayment date. Such notice shall, in addition to setting forth the above information, set forth, in the case of each Certificate called only in part, the portion of the principal represented thereby which is to be prepaid; provided, however, that neither failure to receive such notice so mailed nor any defect in any notice so mailed shall affect the sufficiency of the proceedings for the prepayment of such Certificates or the cessation of accrual of interest represented thereby from and after the date fixed for prepayment. The District has the right to rescind any notice of the optional prepayment of the Certificates by written notice to the Trustee on or prior to the dated fixed for prepayment. Any notice of optional prepayment shall be cancelled and annulled if for any reason funds will not be or are not available on the date fixed for prepayment for the payment in full of the Certificates then called for prepayment, and such cancellation shall not constitute an Event of Default. The District and the Trustee have no liability to the Certificate Owners or any other party related to or arising from such rescission of prepayment. The Trustee shall mail notice of such rescission of prepayment in the same manner as the original notice of prepayment was sent under this Section. Book-Entry Only System The Certificates, when executed and delivered, will be registered in the name of Cede& Co., as registered owner and nominee of DTC. One fully-registered Certificate will be issued for each maturity of the Certificates, each in the aggregate principal amount of such maturity, and will be deposited with DTC. So long as DTC, or Cede & Co. as its nominee, is the registered owner of all Certificates, all payments with respect to the Certificates will be made directly to DTC, and disbursement of such payments to the DTC Participants (defined below)will be the responsibility of DTC, and disbursement of such payments to the Beneficial Owners (defined below) will be the responsibility of the DTC Participants, as more fully described in this Official Statement.

The District and the Trustee are not responsible or liable for the failure of DTC or any DTC Participant to make any payment or give any notice to a Beneficial Owner with respect to the Certificates or an error or delay relating thereto. See "APPENDIX F — Book-Entry Provisions." Transfer and Exchange of Certificates Transfer of Certificates. The registration of any Certificate 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 his duly authorized attorney, upon surrender of such Certificate for cancellation at the Office of the Trustee, accompanied by delivery of a written instrument of transfer in a form approved by the Trustee. Whenever any Certificate or Certificates are surrendered for registration or transfer, the Trustee will execute and deliver a new Certificate or Certificates of the same series, maturity, interest rate and aggregate principal amount, in any authorized denominations. The District will pay all costs of the Trustee incurred in connection with any such transfer, except that the Trustee may require the payment by the Certificate Owner of any tax or other governmental charge required to be paid with respect to such transfer. Exchange of Certificates. Certificates may be exchanged at the Office of the Trustee, for a like aggregate principal amount of Certificates representing other authorized denominations of the same interest rate and maturity. The District will pay all costs of the Trustee incurred in connection with any such exchange, except that the Trustee may require the payment by the Certificate Owner requesting such exchange of any tax or other governmental charge required to be paid with respect to such exchange. Limitations on Transfer or Exchange. The Trustee may refuse to transfer or exchange either(a) any Certificate during the period established by the Trustee for the selection of Certificates for prepayment, or(b) the portion of any Certificate which the Trustee has selected for prepayment. SECURITY FOR THE CERTIFICATES Installment Payments Each Certificate represents a direct, undivided fractional interest in Installment Payments to be made by the District to the Authority under the Installment Sale Agreement. The Authority, pursuant to the Indenture, will assign certain of its rights under the Installment Sale Agreement to the Trustee for the benefit of the owners of the Certificates, including its right to receive Installment Payments and prepayments made under the Installment Sale Agreement and its rights to enforce payment of the Installment Payments when due in the event of a default by the District. Security for the Installment Payments Pursuant to the Installment Sale Agreement, the District pledges as security for its obligation to make the Installment Payments all of the Tax Revenues and Net Revenues, and all moneys on deposit in any of the funds and accounts established and held by the Trustee under the Indenture. The pledge constitutes a lien on the Tax Revenues and Net Revenues for the payment of the Installment Payments in accordance with the terms of the Installment Sale Agreement. 7 June 3, 2021 Regular Board Meeting Agenda Packet- Page 532 of 646 Page 108 of 186 The Indenture defines the following terms: "Net Revenues" means, for any period, an amount equal to all of the Gross Revenues received during such period minus the amount required to pay all Operation and Maintenance Costs coming payable during such period "Gross Revenues" means all gross income and revenue received by the District from the ownership and operation of the Wastewater System, including, without limiting the generality of the foregoing: (a) all income, rents, rates, fees, capacity fees (connection fees), charges or other moneys derived from the services, facilities and commodities sold (including recycled water), furnished or supplied through the facilities of the Wastewater System and payments under the Concord Agreement, (b) the earnings on and income derived from the investment of such income, rents, rates, fees, charges or other moneys to the extent that the use of such earnings and income is limited by or under applicable law to the Wastewater System, and (c) the proceeds derived by the District directly or indirectly from the sale, lease or other disposition of a part of the Wastewater System as permitted in the Installment Sale Agreement. The term "Gross Revenues" does not include (i) Tax Revenues, (ii) customers' deposits or any other deposits subject to refund until such deposits have become the property of the District, (iii)the proceeds of any ad valorem property taxes levied for the purpose of paying general obligation bonds of the District relating to the Wastewater System, and (iv) the proceeds of any special assessments or special taxes levied upon real property within any improvement district for the purpose of paying special assessment bonds or special tax obligations of the District relating to the Wastewater System. "Operation and Maintenance Costs" means the reasonable and necessary costs paid or incurred by the District for maintaining and operating the Wastewater System, determined in accordance with generally accepted accounting principles, including but not limited to (a) all reasonable expenses of management and repair and other expenses necessary to maintain and preserve the Wastewater System in good repair and working order, and (b) all administrative costs of the District that are charged directly or apportioned to the operation of the Wastewater System, such as salaries and wages of employees, employee benefits (including actuarial annual pension payment), overhead, taxes (if any) and insurance.

"Concord Agreement" means that certain Agreement, dated September 10, 1974, between the District and the City of Concord, as amended from time to time, including as amended on November 16, 1976, on June 11, 1982, on October 6, 1985, on June 18, 1987, and on April 9, 2002. See "THE DISTRICT— Concord Agreement"for additional information on the Concord Agreement. Flow of Funds The District previously established the "Wastewater System Funds," which the District agrees in the Installment Sale Agreement to continue to hold and maintain for the purposes and uses set forth in the Installment Sale Agreement. 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 for repayment of any Parity Obligations (including the 2018 Bonds), 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: (i) Deposit and Application of Tax Revenues. On or before each Installment Payment Date, the District will withdraw from the Wastewater System Funds, and transfer to the Trustee for deposit in the Installment Payment Fund, an amount of Tax Revenues which, together with the balance then on deposit in the Installment Payment Fund, is equal to the aggregate amount of the Installment Payment coming due and payable 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 Installment Payments thereafter coming due and payable in such Bond Year, all remaining Tax Revenues received during such Fiscal Year will be released from the pledge and lien under the Installment Sale Agreement 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 paragraph (i) on or before each Installment Payment Date is less than the full amount required to be so transferred, the District will withdraw from the Wastewater System Funds on such Installment Payment Date, and transfer to the Trustee for deposit in the Installment Payment Fund, an amount equal to the amount of such insufficiency. (iii) No Preference or Priority. The District will pay the Installment Payments and the principal of and interest on the Parity Obligations from Net Revenues without preference or priority among the Installment Payments and Parity Obligations. If the amount of Net Revenues on deposit in the Wastewater System Funds is any time insufficient to enable the District to pay when due the Installment Payments and the principal of and interest on the Parity Obligations, such payments shall be made on a pro rata basis. 9 June 3, 2021 Regular Board Meeting Agenda Packet- Page 534 of 646 Page 110 of 186 (iv) Other Uses of Tax Revenues and Net Revenues Permitted. The District agrees to manage, conserve and apply moneys in the Wastewater System Funds in such a manner that all deposits required to be made under any Parity Obligations Documents will be made at the times and in the amounts so required. Subject to the foregoing sentence, the District may at any time and from time to time use and apply moneys in the Wastewater System Funds for 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 Installment Payments. The District agrees that, during the Term of the Installment Sale Agreement, the District will adopt all necessary budgets and make all necessary appropriations of the Installment Payments from the Tax Revenues and Net Revenues. If any Installment Payment requires the adoption by the District of any supplemental budget or appropriation, the District will promptly adopt the same. The covenants on the part of the District contained in this paragraph constitute duties imposed by law and it is 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. No Reserve Fund The District is not funding a reserve fund for the Certificates. Rate Stabilization Fund / Rate Stabilization Account The District has established a fund 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. The fund was established as separate accounts within the Operating & Maintenance and Sewer Construction Fund rather than as a separate sub-fund, and accordingly it is referred to as the Rate Stabilization Account by the District and as the Rate Stabilization Fund in the Indenture. From time to time, the District may deposit amounts in the Rate Stabilization Account, 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. As of May 2021, the Rate Stabilization Account contained $4.76 million. The District may, but is not required to, withdraw from any amounts on deposit in the Rate Stabilization Fund/Account 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/Account 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/Account 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/Account and apply such amounts for any lawful purposes of the District relating to the Wastewater System 10 June 3, 2021 Regular Board Meeting Agenda Packet- Page 535 of 646 Page 111 of 186 Rate Covenant The District agrees to the following rate covenants in the Installment Sale Agreement: Net Revenue 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 Installment Payments and principal of and interest on any Parity Obligations coming due and payable during such Fiscal Year. Gross Revenue 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 Installment Payments and principal of and interest on 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. Transfers from Rate Stabilization Fund. For the purpose of computing the amount of Gross Revenues or Net Revenues for any Fiscal Year for purposes of the rate 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 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 Existing Parity Obligations. As described above, the Installment Payments are payable from and secured by a pledge of Tax Revenues and Net Revenues on a parity with the 2018 Bonds. Additional Parity Obligations. The District has the right to issue or incur other bonds, notes, loans, advances or indebtedness payable from Tax Revenues and/or the Net Revenues on a parity with the 2018 Bonds and the Installment Payments (collectively, "Parity Obligations"), subject to satisfaction of the following conditions: (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 Obligations, 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 Installment Payments and all Parity Obligations then outstanding (including the Parity Obligations then proposed to be issued). 11 June 3, 2021 Regular Board Meeting Agenda Packet- Page 536 of 646 Page 112 of 186 (c) The trustee or fiscal agent for such Parity Obligations must be the same entity performing the functions of Trustee under the Indenture. State Loans. Notwithstanding the foregoing, the District may borrow money from the State and incur State Loans to finance improvements to the Wastewater System, and a State Loan may be treated as a Parity Obligation without meeting the requirements of clause (c), so long as the District complies with clauses (a) and (b) with respect to such State Loan. As of June 2021, the District was finalizing a loan agreement with the State Revolving Fund for a loan in an amount of$173.4 million to fund the Solids Handling Project, which will constitute a Parity Obligation. 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 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 Certificates. Such insurances may be maintained as part of or in conjunction with any other insurance coverage carried by the District, and may be maintained in whole or in part in the form of self-insurance by the District, or in the form of the participation by the District in a joint powers agency or other program providing pooled insurance. The District currently maintains self-insurance funds available for payment of claims below insured deductibles, or above limits, or for non-covered losses. Self-insurance reserves are targeted at $6.5 million. Reserves are replenished annually from sewer service charge rate revenue, based on losses and expenses. 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 12 June 3, 2021 Regular Board Meeting Agenda Packet- Page 537 of 646 Page 113 of 186 destroyed portion of the Wastewater System, and to the extent not so applied, shall be applied on a pro rata basis to redeem the Certificates and any Parity Obligations in accordance with the 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 Certificates 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 Certificates and any Parity Obligations, or which otherwise would impair the rights of the Certificates 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 Certificates and any Parity Obligations in accordance with the Indenture and the related Parity Obligation Documents. See "APPENDIX A— Summary of Principal Legal Documents." Limited Obligation; Absolute Obligation Limited Obligation. The District's obligation to pay the Installment Payments and any other amounts coming due and payable under the Installment Sale Agreement 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 Installment Sale Agreement for the payment of the Installment Payments and such other amounts, nor are any other funds or property of the District liable for the payment of the Installment Payments and any other amounts coming due and payable under the Installment Sale Agreement. Absolute Obligation. The obligations of the District to make the Installment Payments from the Tax Revenues and Net Revenues and to perform and observe the other agreements contained in the Installment Sale Agreement are absolute and unconditional and are not subject to any defense or any right of set-off, counterclaim or recoupment arising out of any breach by the Authority or the Trustee of any obligation to the District or otherwise with respect to the Wastewater System, or out of indebtedness or liability at any time owing to the District by the Authority or the Trustee. Until such time as all of the Installment Payments, all of the Additional Payments and all other amounts coming due and payable thereunder have been fully paid or prepaid, the District(a)will not suspend or discontinue payment of any Installment Payments, Additional Payments or such other amounts, (b)will perform and observe all other agreements contained in the Installment Sale Agreement, and (c) will not terminate the Installment Sale Agreement for any cause, including, without limiting the generality of the foregoing, the occurrence of any acts or circumstances that may constitute failure of consideration, eviction or constructive eviction, destruction of or damage to the Wastewater System, sale of the Wastewater System, the taking by eminent domain of title to or temporary use of any component of the Wastewater System, commercial frustration of purpose, any change in the laws of the United States of America or the State of California or any political subdivision of either thereof or any failure of the Authority or the Trustee to perform and observe any agreement, whether express or implied, or any duty, liability or obligation arising out of or connected with the Indenture or the Installment Sale Agreement. 13 June 3, 2021 Regular Board Meeting Agenda Packet- Page 538 of 646 Page 114 of 186 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 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 14 June 3, 2021 Regular Board Meeting Agenda Packet- Page 539 of 646 Page 115 of 186 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 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 '/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. 15 June 3, 2021 Regular Board Meeting Agenda Packet- Page 540 of 646 Page 116 of 186 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 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 16 June 3, 2021 Regular Board Meeting Agenda Packet- Page 541 of 646 Page 117 of 186 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. The actual valuation impact to the District from successful assessment appeals will occur on the assessment roll prepared after the actual valuation reduction. THE AUTHORITY The Authority is a nonprofit public benefit corporation that was formed to provide financial assistance to the District. The Authority's board of directors is composed of the members of the District's Board of Directors. 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, as well as those living in unincorporated County within the service area, encompassing a total 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) 23rd 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. 17 June 3, 2021 Regular Board Meeting Agenda Packet- Page 542 of 646 Page 118 of 186 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 incinerator furnaces are powered by methane from a nearby landfill. • The District operates a cogeneration facility that uses 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 on average approximately 35 million gallons of wastewater per day ("MGD"). Located in Martinez, the Treatment Plant has a treatment capacity of 54 MGD average dry weather flow and 250 MGD of wet weather flow. The Treatment Plant processed an average daily flow of 35.5 MGD in 2020 and a peak hourly flow of 78.6 MGD during 2020. 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 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 annually for irrigation, landscaping and industrial use. The District 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 18 June 3, 2021 Regular Board Meeting Agenda Packet- Page 543 of 646 Page 119 of 186 system, and ensures that no cross-connections occur between the customer's drinking water system and the District's recycled water system. The District also provides recycled water to residential and commercial customers at no cost through fill-stations at the Martinez treatment plant, where vehicles may obtain vehicle loads of recycled water. 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 current permit governing operation of the HHW collection facility expires on June 30, 2021, and a renewal application is in process. District Management and Employees Board of Directors. The District is governed by a five-member Board of Directors each elected from the District for four-year terms. Commencing with the next election in 2022, the Board will transition from "at-large" to "by-division" elections. There will be five separate election areas or "divisions." Management.

The District has not experienced any interruptions in operations because of employer/employee disputes. 20 June 3, 2021 Regular Board Meeting Agenda Packet- Page 545 of 646 Page 121 of 186 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 ("PEPRX). 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. Provisions and Benefits. 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. The Plans' provisions and benefits in effect as of June 30, 2020, are summarized as follows: Tier Legacy PEPRA Membership Date Before 1/1/13, including On or after Reciprocity 1/11/13 Membership Count 220 54 Employee Rates 11.97% (Average) 11.20% District Rates 56.46% 45.67% 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 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 the matter is now on remand from 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 Supreme Court's ruling generally upholds implementation of the legislative pension reforms, accordingly the pension costs of the District will remain much the same as they have been over the last several fiscal years. Contributions. 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. 21 June 3, 2021 Regular Board Meeting Agenda Packet- Page 546 of 646 Page 122 of 186 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 contribution requirement and payment from the District for the plan year ended December 31, 2019, 2018 and 2017 was as follows: 2019 2018 2017 Covered payroll for plan years ended 12/31 $39,445,629 $37,088,954 $36,405,155 Employer contributions to pension 17,474,682 17,282,356 17,113,394 Employee contributions to pension 4,066,962 3,971,752 3,868,354 Total Contributions $21,541,644 $21,254,108 $20,981,478 Source: Central Contra Costa Sanitary District.

Pursuant to the Governmental Accounting Standards Board ("GASB") Statement 68, the District's proportionate share of the net pension liability from its participation in the multiple-employer cost sharing defined benefit pension plan administered by CCCERA for the past five years were as follows: Proportionate Share of Reporting Date Net Pension Liability December 31, 2015 $91,746,888 December 31, 2016 87,847,116 December 31, 2017 63,806,000 December 31, 2018 90,430,104 December 31, 2019 64,117,450 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. Pension Prefunding Trust Fund. 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, 2021, including trust contributions and interest was $12,019,000. See notes to the financial statements for additional information about the Pension Plan and the pension prefunding trust fund. Paying-Down Portion of Unfunded Liability to CCCERA. By utilizing the net proceeds of the Certificates to finance improvements to the Wastewater System, the District anticipates that rates, charges, and other available funds on hand (including funds in the Pension Prefunding Trust 22 June 3, 2021 Regular Board Meeting Agenda Packet- Page 547 of 646 Page 123 of 186 Fund)will be available to pay-down a substantial portion, or potentially all, of the District's unfunded accrued actuarial pension liabilities of approximately $70.8 million as of the latest actuarial pension valuation date of December 31, 2019. The payment to CCCERA is anticipated to be made subsequent to the date of the COP closing, during late June 2021. By paying down the existing unfunded actuarially accrued liability ("UAAL"), CCCERA's annual charges to the District for the amortization of the currently existing UAAL that were to have been recovered in Fiscal Year 2021- 22 and future fiscal years throughout the 2020s, are expected to be substantially or fully eliminated. By paying down the UAAL, the District expects to save on a net basis by: • Avoiding 7% interest charges on the outstanding UAAL balance assessed by CCCERA, and instead paying the Installment Payments evidenced by the Certificates. • Earning the market return on invested assets by CCCERA, which is targeted at 7% over the long-term (from 2001 to 2020, investment returns averaged approximately 7.7% per year; however, returns varied significantly, ranging from as low as —26.5% in 2008 to as high as 23.5% in 2003 and returns are expected to be similarly volatile in the future). The District has evaluated, with the assistance of its municipal advisor, the risk factors involved in this planned pay-down transaction. The extent of the savings will depend on CCCERA returns, and the interest rate on the Certificates. In the event CCCERA's returns fall substantially short of the anticipated 7% for an extended period of time, the pay-down transaction may not generate savings. Further, dependent on CCCERA investment returns and future changes in actuarial assumptions, additional UAAL may arise in future years. As the District also maintains a Pension Prefunding Trust Fund, some funds may be retained in that Trust in lieu of full repayment of the CCCERA UAAL. 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. Provisions and Benefits. 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 April 2004, 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 plans. The approach followed in Statement No. 43 is generally consistent with the approach adopted for defined benefit 23 June 3, 2021 Regular Board Meeting Agenda Packet- Page 548 of 646 Page 124 of 186 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 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. Pursuant to GASB 75, the District's liability attributed to OPEB for the last five fiscal years were as follows. The significant reduction beginning in Fiscal Year 2018-19 is related to the change to a more cost-effective healthcare provider, CalPERS, effective July 1, 2019. Fiscal Year Net OPEB Liability 2015-160) $54,030,000 2016-17 50,424,241 2017-18 46,350,454 2018-19(2) 11,912,761 2019-20 10,371,508 (1) As FY2015-16 pre-dates the implementation of GASB 75, the GASB 45 unfunded actuarially accrued liability from July 1, 2016 was used. (2) Reduction in FY2018-19 due to change in healthcare provider for OPEB. OPEB Trust Fund. 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, 2020 and 2019, including trust contributions and interest, totalled $69,849,830 and $65,926,014, respectively, and were $80,868,359 as of March 2021. See Note 10 to the District's fiscal year 2019-20 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 2020. 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. The maximum maturity for general investments of the District is one year. Prior approval of the Board 24 June 3, 2021 Regular Board Meeting Agenda Packet- Page 549 of 646 Page 125 of 186 of Directors must be obtained to acquire investments with maturities beyond five years. See "APPENDIX A— Summary of Indenture" for the Permitted Investments definition for the Bonds. 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 March 31, 2021, 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 March 31, 2021, sufficient funds in the Running Expense Fund and Sewer Construction Fund to pay for six months of cash flow needs.

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 2019-20 from Concord/Clayton was approximately 34.1%, and is expected to be about 33% on an ongoing basis. The District requires Concord to pretreat industrial waste. This is accomplished by requiring their industrial customers to pre-treat their discharges to the system. Payments Under Concord Agreement. 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 28 June 3, 2021 Regular Board Meeting Agenda Packet- Page 553 of 646 Page 129 of 186 repairing all sewer mains within the affected area. The District bills and collects sewer service charges for parcels in the affected area and pays the amount collected to the City of Concord. For fiscal year 2019-20, the District paid $45,667 of sewer service charges to the City of Concord for the affected area. Billing and Collection of Sewer Service Charges General Policy. 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. 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. Government-owned and other parcels not receiving a property tax bill are billed under District Code chapter 6.24.120, which 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. 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 29 June 3, 2021 Regular Board Meeting Agenda Packet- Page 554 of 646 Page 130 of 186 expenses incurred by the District in disconnecting any such parcel. No reconnection is made until all charges are paid. • 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 District Code Chapter 6.24.050. • 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 District has experienced full collections because the sewer service charges are collected on the property tax roll and the County has adopted the Teeter Plan. See "— Property Taxes" below.

Sewer Service Charge rates are adopted by the Board after a public process compliant with Proposition 218, including notification, and a public hearing. Proposition 218 protests received opposing the proposed rate increases have been very minimal, especially given the District's large service area. On April 18, 2019, the Board adopted a four-year rate ordinance (Ordinance No. 304), extending through Fiscal Year 2022-23. The ordinance specified that there would be annual check-ins to determine whether the rates should continue as adopted or be adjusted (with a majority vote required to adjust rates downward; any rate change above the level specified in the four year schedule would require a new Proposition 218 process). Four Board financial workshops have been held (on November 4, 2019; March 12, 2020; December 17, 2020; and March 25, 2021)to discuss the District's financial outlook and to receive Board direction on key financial planning matters. • With respect to Fiscal Year 2020-21 rates, the Board on April 16, 2020, deliberated on whether to adjust the previously adopted rates for Fiscal Year 2020-21, and did not adopt changes. However, on May 7, 2020, the Board revisited the matter given the severity of the economic downturn that appeared to be unfolding and voted to not collect the incremental rate increase for Fiscal Year 2020-21, while leaving the entire rate structure in place adopted by Ordinance No. 304, effectively creating a rate increase holiday for Fiscal Year 2020-21. • With respect to Fiscal Year 2021-22 rates, on April 15, 2021, the Board deliberated and by taking no action, allowed the previously adopted rates for Fiscal Year 2021-22 to go- into effect as scheduled for July 2021. Set forth in the following table is a summary of the District's current and adopted Sewer Service Charges. In April 2019, the Board approved the consolidation of most of the District's prior non- residential customer classes into five classes based on combined strength limits, defined as the sum of biochemical oxygen demand (BOD) and total suspended solids (TSS). These customer classes are "Low," "Medium-Low," "Medium," "Medium-High," and "High," and fairly charge those customers for the proportionate cost of collecting and treating their wastewater, based on an updated cost of service study competed in Fiscal Year 2018-19. The change was effective July 1, 2019. 31 June 3, 2021 Regular Board Meeting Agenda Packet- Page 556 of 646 Page 132 of 186 TABLE 7 CENTRAL CONTRA COSTA SANITARY DISTRICT Current and Prior Years Sewer Service Charge User Group Fiscal Year Fiscal Year Fiscal Year Fiscal Year 2019-20 2020-21 2021-22 2022-23 Residential (rate per living unit) Single Family Residence $598 $629 $660 $690 Multi-Family Residence $566 $596 $625 $654 Commercial/Non-Industrial(rates per hundred cubic feet) Low Non-residential uses not listed Up to $6.23 $6.56 $6.87 $7.20 below(no food service) 350 mg/I BOD+ +TSS Medium Food service without Type 1 351 to $6.72/$7.65 $8.05 $8.43 $8.83 -Low hood, shared water meter with 700 mg/I less than 50% food service by BOD+ flow +TSS Medium Shared water meter with 50% or 701 to $9.59 $10.09 $10.57 $11.07 greater food service by flow 1,000 mg/I BOD+ +TSS Medium Food service with Type 1 hood, 1,001 to $10.70 $11.26 $11.79 $12.35 -High supermarkets, hotels and motels 1,300 mg/I with food service, shared water BOD+ meters with bakery +TSS High Mortuaries, bakeries, restaurants Greater $14.18 $14.92 $15.63 $16.37 with grinders or emulsifiers, than breweries with Best Management 1,300 mg/I Practices permit BOD+ +TSS Minimum Annual Charge $566.00 $596.00 $625.00 $654.00 Schools Schools - Daycare, Preschool, University (per hundred $6.23 $6.56 $6.87 $7.20 cubic feet) Schools-Elementary(per student) $7.43 $7.82 $8.19 $8.58 Schools-Intermediate and High School (per student) $14.68 $15.45 $16.18 $16.95 Other Categories Industrial Permit Wastewater Flow(per hundred cubic feet) $4.82 $5.08 $5.32 $5.57 Biological Oxygen Demand (BOD)(per 1,000 pounds) $1,275.00 $1,342.00 $1,406.00 $1,473.00 Total Suspended Solids(TSS)(per 1,000 pounds) $666.00 $701.00 $734.00 $769.00 Fixed $93.69 $98.61 $103.29 $108.20 Special Discharge Permits/Contractual Agreements Determined Determined Determined Determined Individually Individually Individually Individually Source:Central Contra Costa Sanitary District. 32 June 3, 2021 Regular Board Meeting Agenda Packet- Page 557 of 646 Page 133 of 186 TABLE 8 CENTRAL CONTRA COSTA SANITARY DISTRICT Historical Residential Sewer Service Charges Single Family Annual Sewer Service Multi-Family Annual Sewer Charge (SSC) Service Charge SSC (') Fiscal Year Operations Capital(') Total Operations Capital(') Total 1990-1991 136 0 136 136 0 136 1991-1992 151 0 151 151 0 151 1992-1993 160 5 165 160 5 165 1993-1994 160 25 185 160 25 185 1994-1995 160 28 188 160 28 188 1995-1996 157 31 188 157 31 188 1996-1997 157 31 188 157 31 188 1997-1998 157 31 188 157 31 188 1998-1999 157 31 188 157 31 188 1999-2000 157 31 188 157 31 188 2000-2001 185 15 200 185 15 200 2001-2002 204 20 224 204 20 224 2002-2003 207 41 248 207 41 248 2003-2004 218 54 272 218 54 272 2004-2005 204 76 280 204 76 280 2005-2006 234 46 280 234 46 280 2006-2007 213 76 289 213 76 289 2007-2008 242 58 300 242 58 300 2008-2009 260 51 311 260 51 311 2009-2010 292 19 311 292 19 311 2010-2011 300 11 311 300 11 311 2011-2012 302 39 341 302 39 341 2012-2013 344 27 371 344 27 371 2013-2014 365 40 405 365 40 405 2014-2015 416 23 439 416 23 439 2015-2016 422 49 471 415 48 463 2016-2017 432 71 503 418 69 487 2017-2018 447 83 530 432 81 513 2018-2019(3) 400 167 567 388 161 549 2019-2020 408 190 598 386 180 566 2020-2021(4) 263 335 629/598** 249 317 596/566* (1) All residential accounts paid a flat annual sewer service charge shown above per residential unit through 2014-2015. In 2015-2016,as a result of a cost of service study,the District added a separate--multi-family rate.The charge for commercial users consists of an annual rate based on business type and the measured volume of water usage in 100 cubic feet(HCF). (2) Beginning in fiscal year 1992-93 the District began allocating a portion of the Sewer Service Charge to 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. (4) Rates for this year were legally adopted at$629 for Single Family and$596 for multi-family, however, the Board voted to continue collection at the previous year's adopted rates due to the COVID-19 pandemic. The same treatment was provided for non-residential rates.

Source:Central Contra Costa Sanitary District comprehensive financial annual reports(CAFRs). Capacity Fees Used for Capital Improvements General. New users who are connected to the Wastewater System are charged Capacity Fees that are used to fund District Capital Improvements. The District charges (rates effective July 1, 2021) a Capacity Fee of $7,351 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 $9,042 per RUE. A RUE is the burden 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 wastewater burden, 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. 35 June 3, 2021 Regular Board Meeting Agenda Packet- Page 560 of 646 Page 136 of 186 Historical and Current Capacity Fees.

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. Due to the Teeter Plan, the District receives 100% of its property taxes each year.

The District is working to comply with new Federal Clean Air Act Section 129 sewage sludge incinerator regulations related to sewage sludge incinerators that went into effect in March 2016. This regulation is related to pollutant emission limits. Prior to the implementation of these regulations, the District could use a furnace exhaust bypass damper as needed to prevent equipment damage or protect worker safety. With the new regulations, each time the bypass is used, the District must inform the Bay Area Air Quality Management District (BAAQMD) of the release of particulate matter. The method of information to the BAAQMD is to prepare a reportable compliance activity(RCA) report. From January 2016 to March 2021, the District has had 13 RCAs. As a result of these RCAs and an event related to the District's cogeneration system, the District has received thirteen notices of violation (NOVs) over this five-year period. The District is still awaiting a response on the other RCAs, which may not necessarily result in an NOV. To help mitigate this issue, the District conducted a pilot test of new wet scrubber technologies during recent fiscal years and is currently in the bidding phase to install new scrubber technologies which was 38 June 3, 2021 Regular Board Meeting Agenda Packet- Page 563 of 646 Page 139 of 186 procured by the District to meet current and upcoming air regulations (both local and federal). Construction of the new wet scrubbers is expected to be completed by 2025. DISTRICT FINANCES Financial Statements Basis of Accounting. 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. 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. Rate Stabilization Accounts for Running Expense and Sewer Construction are maintained as accounts within those sub-funds. Separate Pension Prefunding Trust and Other Post-Employment Benefits (OPEB)Trust are also maintained to accumulate funds for payment of pension and OPEB liabilities, respectively. Audited Financial Statements. The District's fiscal year 2019-20 financial statements were audited by Maze Accountancy Corporation, Pleasant Hill, California and are attached as Appendix C. Maze Accountancy Corporation has consented to the inclusion of the fiscal year 2019-20 audited financial statements in this Official Statement but has not reviewed this Official Statement.

In addition, the District is finalizing the terms of a $173 million State Revolving Fund Loan for its Solids Handling Project, which is anticipated to close in Fiscal Year 2021-22 and will constitute a Parity Obligation. Capital Improvement Plan Overview. 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 CIP The District's current Capital Improvement Plan covers the ten-year period from fiscal year 2021-22 through 2030-31. The plan includes projected expenditures totaling approximately $939.7 million (2021 dollars). Capital improvement projects are grouped into four programs: Treatment Plant, Collection System, General Improvements, Recycled Water, and Contingency. 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 $497.2 million (2021 dollars), comprising 52.9% 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$334.9 million (2021 dollars), the Collection System Program comprises 35.6% 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 large diameter sewers and force mains. Overall, these 41 June 3, 2021 Regular Board Meeting Agenda Packet- Page 566 of 646 Page 142 of 186 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 $22.6 million (2021 dollars), representing 2.4% 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 $59.8 million (2021 dollars), comprising 6.4% 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 clearwells with new steel circular storage tanks, upgrading the filters 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. • Contingency: The Ten-Year CIP, and each annually adopted budget, also provides for unallocated funding that can be applied towards unidentified projects, or costs in excess of budgeted amounts. The District's Ten-Year CIP provides for $25.2 million (2021 dollars) in contingency funding, comprising 2.7% of the overall CIP funding. Contingency funds may be transferred to new projects or existing projects in amounts up to $200,000 and $500,000 respectively, by the General Manager, with transfers above that amount requiring Board approval. 42 June 3, 2021 Regular Board Meeting Agenda Packet- Page 567 of 646 Page 143 of 186 Ten-Year CIP Drivers Overview. Projects included in the current 10-Year 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: • 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 serves as a tool for maintaining a high level of service, establishing long-term fiscally responsible policies for customers, and provides a clear direction for the District. The 10 year-CIP projection is updated 43 June 3, 2021 Regular Board Meeting Agenda Packet- Page 568 of 646 Page 144 of 186 annually, and typically includes(1)inflating the costs to present year dollars; (2)reflecting any known changes in priorities or project costs; (3) reshaping annual spending and project costs by year to reflect financial plan or budget constraints. 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: • Nutrient Removal BACWA (Bay Area Clean Water Agencies) Levels 2/3: Possibly beyond 20 years ** • Recycled Water Exchange (Refinery Recycled Water) Project— up to 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 the District. ** Projects identified but not currently required by regulations.

June 3, 2021 Regular Board Meeting Agenda Packet- Page 570 of 646 Page 146 of 186 Financing of the Capital Improvement Plan. 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 FY 2021-22 budget, adopted by the Board on June 3, 2021, was developed prior the finalization of this COP offering. There is an anticipation that the budget will be amended to reflect a revised sources and uses of funds resulting from the availability of these proceeds. 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. In FY 2020-21, the District developed a program that allows commercial customers to finance capacity fees over a period of 10-15 years at an interest rate established by the District annually. The Board has had 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 years 2020-21 through potentially FY 2022-23, with debt financing. Additionally, a $173 million State Revolving Fund Loan pending finalization is anticipated to fund the Solids Handling Project that is expected to begin construction in FY 2021-22 and extend through FY 2025-26. While the current 10 year financial plan does not anticipate it at this time, further 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 certificates of participation of revenue bond issuances. Anticipated Sources and Uses. The anticipated use of debt proceeds is to provide funding for planned Fiscal Year 2021-22 capital projects, and also to provide reimbursement for revenues and reserves used towards funding a portion of the projects in the Fiscal Year 2020-21 spending plan. Actual reimbursement will be determined by District management based on spending during the remainder of Fiscal Year 2020-21, and other factors, with the total reimbursement expected to approximate $20,000,000. The balance of issuance proceeds are anticipated to be used for Fiscal Year 2021-22 capital project funding, after payment of costs of issuance. By using the proceeds of the Certificates to finance a portion of the capital project spending in these two fiscal years, the District will make available funds that are planned to be used for the 46 June 3, 2021 Regular Board Meeting Agenda Packet- Page 571 of 646 Page 147 of 186 purpose of reducing or paying off its unfunded actuarially accrued liability with CCCERA.

The projections are based on the following key assumptions. Gross Revenues: The following assumptions have been made with respect to the projections of Gross Revenues: Rate Base Growth: The projections assume an approximately 0.35-0.42% 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) 4.9% in fiscal year 2021-22, (ii) 4.7% in fiscal year 2022-23, and (iii) 4% in fiscal year 2023-24. The Board approved a four-year schedule of rates which extends through FY 2022-23. The District can provide no assurances it will be able to increase rates in FY 2023-24 as projected, given such procedure is subject to State Constitutional requirements and future Board action. See "RISK FACTORS — Proposition 218." Tax Revenues: The projections assume 3.0% annual increases in property tax revenues, beginning in fiscal year 2021-22. Interest earnings: The projections assume interest earnings on District funds as follows: (i) 1.5% in fiscal year 2022-23, (ii) 1.75% in fiscal year 2023-24, and (iii) 2.00% in fiscal year 2024-25. Operation and Maintenance Costs: The projections assume annual operation and maintenance expenses of the Wastewater System will increase as follows: (i) 7.8% in fiscal year 2022-23, (ii) 5.2% in fiscal year 2023-24, (iii) 4.8% in fiscal year 2024-25. Debt Service: The projections assume debt issuances of: (i)$60 million in fiscal year 2020- 21 via the execution and delivery of the Certificates, and (ii) $173.4 million of State Revolving Fund Loan draws between fiscal year 2020-21 and fiscal year 2025-2026. The projections reflect the debt service on the outstanding 2018 Bonds and on the Certificates; however, no debt service is reflected with respect to the State Revolving Fund loan because loan repayments will commence outside the projection period. 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 Installment Payments evidenced by the Certificates is limited to Net Revenues and Tax Revenues, and the District is not obligated to apply any other revenues to pay the Installment Payments or the Certificates. 49 June 3, 2021 Regular Board Meeting Agenda Packet- Page 574 of 646 Page 150 of 186 TABLE 17 CENTRAL CONTRA COSTA SANITARY DISTRICT Projected Revenues, Expenses and Debt Service Coverage (In $000's except service data and coverage) Fiscal Year Ended June 30, 2021 2022 2023 2024 2025 Gross Revenues Sewer services charges(O&M) $71,700 $105,701 $ 75,311 $ 80,048 $ 78,588 Sewer services charges(Capital) 30,166 2,243 (') 36,989 39,598 46,405 Sewer charges-City of Concord(O&M) 15,400 13,891 16,840 17,450 18,491 Sewer charges-City of Concord(Capital)8 15,300 8,701 9,161 8,211 16,773 Other service charges 2,707 2,842 2,927 3,015 _ 3,106 Total Gross Revenues 135,273 133,378 141,228 148,322 163,363 Operation and Maintenance Costs(2) Operations 42,624 40,643 43,066 45,239 47,326 Engineering 16,466 14,861 15,484 16,533 17,525 Recycled Water 1,522 1,611 1,513 1,585 1,655 Administrative and general 24,450 22,327 25,548 26,732 27,881 Total Operation and Maintenance Costs 85,062 79,442 85,611 90,089 94,387 Total Operating Income(Loss) 50,211 53,936 55,617 58,233 68,976 Non-Operating Revenue Capacity fees(connection fees) 5,777 5,950 5,587 5,656 5,004 Contributed capital 1,000 1,000 1,000 1,000 1,000 Permit and inspection fees 1,897 1,882 1,939 1,997 2,057 Interest earnings 210 180 535 657 787 Other interest earnings(capital reserve) 310 319 1,345 1,771 2,268 Other Income(3) 300 298 304 310 316 Total Non-Operating Revenues: 9,494 9,629 10,710 11,3 91 11,432 Tax Revenues 19,496 19,831 20,426 21,039 21,670 Rate Stabilization Fund Account Draws/(Deposits)(') (2,150) Annual DebtService(s)* 2,518 2,511 10,222 9,738 10,357 Debt Service Coverage Net Revenues+Tax Revenues(') 79,201 83,396 86,753 90,663 102,078 Debt Service Coverage' 31.5 x 33.2 x 8.5 x 9.3 x 9.9 x Adjusted Net Revenues+Tax Revenues(') 54,974 67,745 71,005 75,796 79,301 Debt Service Coverage' 21.8 x 27.0 x 6.9 x 7.8 x 7.7 x *Preliminary;subject to change.

Source:Central Contra Costa Sanitary District. 50 June 3, 2021 Regular Board Meeting Agenda Packet- Page 575 of 646 Page 151 of 186 RISK FACTORS The following factors, along with other information in this Official Statement, should be considered by potential investors in evaluating the risks in the purchase of the Certificates. 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 Installment Sale Agreement. 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. On March 29, 2021, the California Supreme Court issued a ruling in the case of Kaanaana v. Barrett Business Services, Inc. The Court held that, although the prevailing wage was traditionally interpreted to apply to construction-related work only, the language at issue does not include such limitation when the work is performed for public utility, reclamation, and other special districts. According to the Court, any work whatsoever for such public entities must be paid at prevailing wages. The District is currently assessing the impact the ruling will have on costs, but does not expect that the impact will be significant, as public works are already subject to prevailing wage, with the result that the impact on the capital budget is not expected to be material. With respect to the Operating & Maintenance budget ($91 million for Fiscal Year 2021-22), approximately 73% of the costs are employee salaries and benefits, with the remaining 27% (or $24.5 million), covering all other costs such as for services, supplies, and other expenses. Of the 27%, approximately 14% of the total Operating & Maintenance budget (or $12.9 million) is for services, for which the ruling is to have some impact on certain of the costs. The impact is not expected to be significant, and if necessary a budget amendment for the Fiscal Year 2021-22 will be adopted to provide for such increases. 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. 51 June 3, 2021 Regular Board Meeting Agenda Packet- Page 576 of 646 Page 152 of 186 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 Obligation Although the District has covenanted not to issue additional obligations payable from Net Revenues and Tax Revenues on a senior basis to the Installment Payments, the Installment Sale Agreement 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 Installment Payments (see "SECURITY FOR THE CERTIFICATES — Parity Obligations" above). The coverage tests described in "SECURITY FOR THE CERTIFICATES — Parity Obligations" involve, to some extent, projections of Net Revenues and Tax Revenues. If such indebtedness is issued, the debt service coverage for the Installment Payments 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 payment of the Installment Payments and such Parity Obligations. 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 Certificates. 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 52 June 3, 2021 Regular Board Meeting Agenda Packet- Page 577 of 646 Page 153 of 186 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 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 CERTIFICATES—Security for the Installment Payments." 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 53 June 3, 2021 Regular Board Meeting Agenda Packet- Page 578 of 646 Page 154 of 186 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, subsequent 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 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 current sewer rates were adopted on June 5, 2008 by Resolution No. 2008-063 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. 54 June 3, 2021 Regular Board Meeting Agenda Packet- Page 579 of 646 Page 155 of 186 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 make Installment Payments, the Trustee, as assignee of the Authority, has the right to accelerate the total unpaid principal amounts of the Installment Payments. 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 Installment Payments. Limitations on Remedies Available; Bankruptcy The enforceability of the rights and remedies of the owners of the Certificates 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. Limited Obligation The District's obligation to make Installment Payments is a special obligation of the District payable solely from Net Revenues and Tax Revenues and other funds provided for in the Installment Sale Agreement. 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 Installment Payments. The obligation of the District to pay Installment Payments 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 55 June 3, 2021 Regular Board Meeting Agenda Packet- Page 580 of 646 Page 156 of 186 additional limitations that could have the effect of reducing the Net Revenues or the Tax Revenues and adversely affecting the security of the Certificates. Loss of Tax Exemption As discussed in this Official Statement under the caption "TAX MATTERS," interest with respect to the Certificates could become includable in gross income for purposes of federal income taxation retroactive to the date the Certificates were issued, as a result of future acts or omissions of the District in violation of its covenants in the Installment Sale Agreement or Indenture. Should such an event of taxability occur, the Certificates 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 Certificates 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 2020-21 (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, except that certain operating information and reserve fund balance information was not timely filed for Fiscal Years 2012-13 through 2015-16. Beginning with Fiscal Year 2016-17, all required information is included in the District's comprehensive annual financial report (CAFR). [CONFIRM/UPDATE] TAX MATTERS Federal Tax Status. In the opinion of Jones Hall, A Professional Law Corporation, San Francisco, California, Special Counsel, subject, however to the qualifications set forth below, under existing law, the portion of Installment Payments designated as and comprising interest and received by the owners of the Certificates 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. 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 must be satisfied subsequent to the execution and delivery of the Certificates in order that the interest with respect thereto be, and continue to be, excludable from gross income for federal income tax purposes. The District has made certain representations and covenants in order to comply with each such requirement. Inaccuracy of those representations, or failure to comply with certain of those covenants, may cause the inclusion of such interest in gross income 56 June 3, 2021 Regular Board Meeting Agenda Packet- Page 581 of 646 Page 157 of 186 for federal income tax purposes, which may be retroactive to the date of execution and delivery of the Certificates. Tax Treatment of Original Issue Discount and Premium. If the initial offering price to the public at which a Certificate 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 at which a Certificate is sold is greater than the amount payable at maturity thereof, then such difference constitutes "bond premium"for purposes of federal income taxes and State of California personal income taxes. De minimis original issue discount and bond 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 Certificate 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 Certificates to determine taxable gain upon disposition (including sale, redemption, or payment on maturity) of such Certificate. The Tax Code contains certain provisions relating to the accrual of original issue discount in the case of purchasers of the Certificates who purchase the Certificates after the initial offering of a substantial amount of such maturity. Owners of such Certificates should consult their own tax advisors with respect to the tax consequences of ownership of Certificates with original issue discount, including the treatment of purchasers who do not purchase in the original offering to the public at the first price at which a substantial amount of such Certificates is sold to the public. Under the Tax Code, bond premium is amortized on an annual basis over the term of the Certificate (said term being the shorter of the Certificate's maturity date or its call date). The amount of bond premium amortized each year reduces the adjusted basis of the owner of the Certificate for purposes of determining taxable gain or loss upon disposition. The amount of bond premium on a Certificate is amortized each year over the term to maturity of the Certificate on the basis of a constant interest rate compounded on each interest or principal payment date (with straight-line interpolations between compounding dates). Amortized Certificate premium is not deductible for federal income tax purposes. Owners of premium Certificates, 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 Certificates. California Tax Status. In the further opinion of Special Counsel, the portion of Installment Payments designated as and comprising interest and received by the owners of the Certificates is exempt from California personal income taxes. Other Tax Considerations. Current and future legislative proposals, if enacted into law, clarification of the Tax Code or court decisions may cause interest with respect to the Certificates to be subject, directly or indirectly, to federal income taxation or to be subject to or exempted from state income taxation, or otherwise prevent beneficial owners from realizing the full current benefit of the tax status of such interest. The introduction or enactment of any such legislative proposals, clarification of the Tax Code or court decisions may also affect the market price for, or marketability of, the Certificates. It cannot be predicted whether or in what form any such proposal 57 June 3, 2021 Regular Board Meeting Agenda Packet- Page 582 of 646 Page 158 of 186 might be enacted or whether, if enacted, such legislation would apply to Certificates issued prior to enactment. The opinions expressed by Special Counsel are based upon existing legislation and regulations as interpreted by relevant judicial and regulatory authorities as of the date of such opinion, and Special Counsel has expressed no opinion with respect to any proposed legislation or as to the tax treatment of interest with respect to the Certificates, or as to the consequences of owning or receiving interest with respect to the Certificates, as of any future date. Prospective purchasers of the Certificates should consult their own tax advisors regarding any pending or proposed federal or state tax legislation, regulations or litigation, as to which Special Counsel expresses no opinion. Owners of the Certificates should also be aware that the ownership or disposition of, or the accrual or receipt of interest with respect to, the Certificates may have federal or state tax consequences other than as described above. Other than as expressly described above, Special Counsel expresses no opinion regarding any federal or state tax consequences arising with respect to the Certificates s, the ownership, sale or disposition of the Certificates, or the amount, accrual or receipt of interest with respect to the Certificates. The form of the proposed opinion of Special Counsel is attached as APPENDIX E. NO LITIGATION There is no action, suit or proceeding known to be pending or threatened, restraining or enjoining the execution of the Installment Sale Agreement, the Indenture or the Certificates or in any way contesting or affecting the validity of the Installment Sale Agreement, the Indenture or the Certificates. 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 Installment Sale Agreement, the Indenture or the Certificates. RATING S&P Global Ratings, a division of Standard & Poor's Financial Services LLC ("S&P") has assigned the Certificates a rating of Such rating reflects only the views of such organization and any desired explanation of the significance of such rating should be obtained from S&P, at the following address: S&P Global Ratings, 55 Water Street, New York, New York 10041. The District has furnished to S&P certain materials and information with respect to the District and the Certificates. Generally, a rating agency bases its ratings on the information and materials furnished to it and on investigations, studies and assumptions of its own. There is no assurance such ratings will continue for any given period of time or that such ratings will not be revised downward or withdrawn entirely by the rating agency, if in the judgment of such rating agency, circumstances so warrant. The District and the Municipal Advisor undertake no responsibility to oppose any such proposed revision or withdrawal. Any such downward change in or withdrawal of any rating might have an adverse effect on the market price or marketability of the Certificates. 58 June 3, 2021 Regular Board Meeting Agenda Packet- Page 583 of 646 Page 159 of 186 APPROVAL OF LEGALITY Legal matters incident to the delivery of the Certificates are subject to the approving opinion of Jones Hall, A Professional Law Corporation, San Francisco, California, Special Counsel.

A-1 June 3, 2021 Regular Board Meeting Agenda Packet- Page 585 of 646 Page 161 of 186 APPENDIX B CONTRA COSTA COUNTY GENERAL INFORMATION The following information relating to the District, Contra Costa County, and the State of California is supplied solely for the purposes of information. The District's obligation to pay the Installment Payments and any other amounts coming due and payable under the Installment Sale Agreement are a special obligation of the District limited solely to the Tax Revenues and the Net Revenues; the Installment Payments are not an obligation of the County, the State or any political subdivisions other than the District. THE COUNTY General Contra Costa County (the "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-3 June 3, 2021 Regular Board Meeting Agenda Packet- Page 589 of 646 Page 165 of 186 Effective Buying Income "Effective Buying Income" is defined as personal income less personal tax and nontax payments, a number often referred to as "disposable" or "after-tax" income. Personal income is the aggregate of wages and salaries, other labor-related income (such as employer contributions to private pension funds), proprietor's income, rental income (which includes imputed rental income of owner-occupants of non-farm dwellings), dividends paid by corporations, interest income from all sources, and transfer payments (such as pensions and welfare assistance). Deducted from this total are personal taxes (federal, state and local), nontax payments (fines, fees, penalties, etc.) and personal contributions to social insurance. According to U.S. government definitions, the resultant figure is commonly known as "disposable personal income." The following table summarizes the total effective buying income for the County, the State and the United States for the period 2017 through 2021.

Transportation The County provides alternative commute options for those without cars or who choose to commute in an environmentally friendly manner. The Bay Area Rapid Transit BART train network stops in many cities in the County, and the County Connection bus service serves areas not immediately adjacent to BART stations. Recently, the BART system was extended into the northeastern portion of the County through the construction of approximately 10 miles of new track between the existing Pittsburg/Bay Point BART Station and the new Antioch BART station. Construction of the extension began in early 2011 and service to the station began in May 2018. In the summer of 2016, the Highway 4 expansion project was completed, providing additional traffic improvement to a major east-west highway artery in the County. The project included expanding Highway 4 from four to eight lanes, and incorporates the BART extension project described above. In addition, the local transportation demand management organization 511 Contra Costa offers services to County residents who wish to switch from single occupancy vehicle driving to greener modes. The County also has two airports that are not currently providing passenger service: (1) Buchanan Field Airport, located in Concord and (2) Byron Airport, located two miles south of Byron.

Approximately 64% of County adult residents have attended college, and approximately 49% of County adult residents have completed four or more years of college. There are nine privately operated hospitals and one public hospital in the County, with a combined total of approximately 1,900 beds. Three of the private hospitals are run by Kaiser, the largest health maintenance organization in the United States. Kaiser has opened a new hospital in Richmond with new critical care beds, surgical suites and a full service emergency department. The public hospital is Contra Costa Regional Medical Center ("CCRMC"), a 156- bed facility that the County rebuilt and opened to the public in 1998 on the existing campus in Martinez. Since completion of the hospital in 1998, the County has completed a public health/clinical laboratory in 2001 and has initiated construction of a new ambulatory care clinic on the campus of CCRMC.

D-5 June 3, 2021 Regular Board Meeting Agenda Packet- Page 598 of 646 Page 174 of 186 Section 10. Additional Information.

If the District chooses to include any information in any Annual Report or notice of occurrence of a Listed Event in addition to that which is specifically required by this Disclosure Certificate, the District shall have no obligation under this Disclosure Certificate to update such information or include it in any future Annual Report or notice of occurrence of a Listed Event.

D-6 June 3, 2021 Regular Board Meeting Agenda Packet- Page 599 of 646 Page 175 of 186 Date: 12021 CENTRAL CONTRA COSTA SANITARY DISTRICT By: Name: Title: D-7 June 3, 2021 Regular Board Meeting Agenda Packet- Page 600 of 646 Page 176 of 186 APPENDIX E FORM OF SPECIAL COUNSEL OPINION [Closing Date] Board of Directors Central Contra Costa Sanitary District 5019 Imhoff Place Martinez, California 94553 OPINION: $ Wastewater Revenue Certificates of Participation (Central Contra Costa Sanitary District) Members of the Board of Directors: We have acted as special counsel to the Central Contra Costa Sanitary District (the "District") in connection with the delivery by the District of the Installment Sale Agreement dated as of June 1, 2021 (the "Installment Sale Agreement") between Central Contra Costa Sanitary District Facilities Financing Authority (the "Authority"), as seller, and the District, as purchaser. Under an Indenture of Trust, dated as of June 1, 2021 (the "Indenture") among the District, the Authority and U.S. Bank National Association, as trustee (the "Trustee"), the Trustee has executed and delivered the above-captioned certificates of participation on the date hereof (the "Certificates"). In such capacity, we have examined such law and such certified proceedings, opinion, certifications and other documents as we have deemed necessary to render this opinion. The Certificates evidence the direct, undivided fractional interests of the owners thereof in Installment Payments to be made by the District under the Installment Sale Agreement (the "Installment Payments"), which have been assigned by the Authority to the Trustee. The District authorized execution and delivery of the Installment Sale Agreement, the Indenture and the Certificates pursuant to a resolution of the Board of Directors of the District adopted on , 2021 (the "Resolution"). Regarding questions of fact material to our opinion, we have relied on representations of the District contained in the Installment Sale Agreement and the Indenture, and in the certified proceedings and other certifications of public officials furnished to us,without undertaking to verify the same by independent investigation. Based on the foregoing, we are of the opinion that, under existing law: 1. The District is a duly created and validly existing sanitary district, with the power to adopt the Resolution, enter into the Installment Sale Agreement and the Indenture, and perform the agreements on its part contained therein. E-1 June 3, 2021 Regular Board Meeting Agenda Packet- Page 601 of 646 Page 177 of 186 2. The Installment Sale Agreement and the Indenture have been duly authorized, executed and delivered by the District, and constitute the valid and binding obligations of the District, enforceable against the District. 3. The Certificates have been validly executed and delivered by the Trustee under the Indenture and, by virtue of the assignment made by the Authority, the owners of the Certificates are entitled to the benefits of the Installment Sale Agreement. 4. The portion of the Installment Payments designated as and comprising interest and received by the owners of the Certificates is excluded from gross income for federal income tax purposes and is not an item of tax preference for purposes of the federal alternative minimum tax. The opinions set forth in the preceding sentence are subject to the condition that the District comply with all requirements of the Internal Revenue Code of 1986, as amended, that must be satisfied subsequent to the execution and delivery of the Certificates in order that the interest with respect thereto be, and continue to be, excludable from gross income for federal income tax purposes. The District has made certain representations and covenants in order to comply with each such requirement. Inaccuracy of those representations, or failure to comply with certain of those covenants, may cause the inclusion of such interest in gross income for federal income tax purposes, which may be retroactive to the date of delivery of the Installment Sale Agreement. 5. The portion of the Installment Payments designated as and comprising interest and received by the owners of the Certificates is exempt from personal income taxation imposed by the State of California. We express no opinion regarding any other tax consequences arising with respect to the ownership, sale or disposition of, or the amount, accrual or receipt of interest on, the Installment Sale Agreement or the Certificates. The rights of the owners of the Certificates and the enforceability of the Installment Sale Agreement and the Indenture are limited by bankruptcy, insolvency, reorganization, moratorium and other similar laws affecting creditors' rights generally, and by equitable principles, whether considered at law or in equity. This opinion is given as of the date hereof, and we assume no obligation to revise or supplement this opinion to reflect any facts or circumstances that may hereafter come to our attention, or any changes in law that may hereafter occur. Our engagement with respect to this matter has terminated as of the date hereof. Respectfully submitted, A Professional Law Corporation E-2 June 3, 2021 Regular Board Meeting Agenda Packet- Page 602 of 646 Page 178 of 186 APPENDIX F BOOK ENTRY-ONLY SYSTEM The following description of the Depository Trust Company ("DTC'), the procedures and record keeping with respect to beneficial ownership interests in the Certificates, payment of principal, interest and other payments on the Certificates to DTC Participants or Beneficial Owners, confirmation and transfer of beneficial ownership interest in the Certificates and other related transactions by and between DTC, the DTC Participants and the Beneficial Owners is based solely on information provided by DTC. 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 Certificates (the "Issuer') nor the trustee, fiscal agent or paying agent appointed with respect to the Certificates (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 Certificates, (b) certificates representing ownership interest in or other confirmation or ownership interest in the Certificates, or(c) redemption or other notices sent to DTC or Cede & Co., its nominee, as the registered owner of the Certificates, 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 securities (the "Certificates"). The Certificates 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 Certificates, 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 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 2.2 million issues of U.S. and non-U.S. equity, corporate and municipal debt issues, and money market instrument 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, in turn, is owned by a number of Direct F-1 June 3, 2021 Regular Board Meeting Agenda Packet- Page 603 of 646 Page 179 of 186 Participants of DTC and Members of the National Securities Clearing Corporation, Fixed Income Clearing Corporation, and Emerging Markets Clearing Corporation (NSCC, FICC, and EMCC, also subsidiaries of DTCC), as well as by the New York Stock Exchange, Inc., the American Stock Exchange LLC, and the National Association of Securities Dealers, Inc. 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, and clearing corporations that clear through or maintain a custodial relationship with a Direct Participant, either directly or indirectly ("Indirect Participants"). DTC has Standard & Poor's highest rating: AAA. 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 and www.dtc.org. 3. Purchases of Certificates under the DTC system must be made by or through Direct Participants, which will receive a credit for the Certificates on DTC's records. The ownership interest of each actual purchaser of each Certificate ("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 Certificates 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 Certificates, except in the event that use of the book-entry system for the Certificates is discontinued. 4. To facilitate subsequent transfers, all Certificates 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 Certificates 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 Certificates; DTC's records reflect only the identity of the Direct Participants to whose accounts such Certificates 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 Certificates may wish to take certain steps to augment transmission to them of notices of significant events with respect to the Certificates, such as redemptions, tenders, defaults, and proposed amendments to the security documents. For example, Beneficial Owners of Certificates may wish to ascertain that the nominee holding the Certificates 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 Certificates 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. F-2 June 3, 2021 Regular Board Meeting Agenda Packet- Page 604 of 646 Page 180 of 186 7. Neither DTC nor Cede & Co. (nor such other DTC nominee) will consent or vote with respect to the Certificates 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 Certificates are credited on the record date (identified in a listing attached to the Omnibus Proxy). 8. Redemption proceeds, distributions, and interest payments on the Certificates 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 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 Certificates 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 certificates 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.
