Both the Supply Assurance and the Individual Supply Guarantees identified are e xpressed in terms of daily deliveries on an annual average basis and do not themselves constitute a guarantee by San Francisco to meet peak daily or hourly demands of the Wholesale Customers, irrespective of what those peak demands may be. The parties acknowledge, however, that the Regional Water System has been designed and constructed to meet peak daily and hourly demands and that its capacity to do so has not yet been reached. San Francisco agrees to operate the Regional Water System to meet peak requirements of the Wholesale Customers to the extent possible without adversely affecting its ability to meet peak demands of Retail Customers. The Agreement shall not preclude San Francisco from undertaking to meet specific peak demand requirements of individual Wholesale Customers in their Individual Water Sales Contracts.

The Supply Assurance is perpetual and shall survive the expiration or earlier termination of the Agreement.

Similarly, the Individual Supply Guarantees and/or the Individual Water Sales Contr acts are perpetual and shall survive the expiration or earlier termination of the Agreement or the Individual Water Sales Contracts.

The amount of water made available by San Francisco to the Wholesale Customers is subject to reduction, to the extent and for the period made necessary by reason of water shortage, Drought, Emergencies, or by malfunctioning or rehabilitation of facilities in the Regional Water System. The amount of water made available to the Wholesale Customers may not be reduced, however, merely because the water recycling and groundwater projects which WSIP envisions to be constructed within San Francisco, or the conservation programs intended to reduce water use by Retail Customers that are included in the WSIP, do not generate the yield or savings (10 MGD combined) anticipated by San Francisco.

B-6
Allocation of Supply Assurance
A portion of the Supply Assurance has been allocated among 24 of the 26 Wholesale Customers. Three Wholesale Customers do not have Individual Supply Guarantees. The cit ies of San José and Santa Clara do not have an Individual Supply Guarantee because San Francisco has provided water to them on a temporary and interruptible basis. The City of Hayward does not have an Individual Supply Guarantee because of the terms of the 1962 contract between it and San Francisco.

If the total amount of water delivered by San Francisco to Hayward and to the Wholesale Customers with Individual Supply Guarantees exceeds 184 MGD over a period of three consecutive fiscal years (i.e., July 1 t hrough June 30), then the Individual Supply Guarantees of those Wholesale Customers shall be reduced pro rata so that their combined entitlement and the sustained use by Hayward does not exceed 184 MGD.

It is the responsibility of each Wholesale Customer to limit its purchases of water from San Francisco so as to remain within its Individual Supply Guarantee. San Francisco is not liable to any Wholesale Customer or obligated to supply more water to any Wholesale Customer individually or to the Wholesale Cus tomers collectively than the amount to which it or they are otherwise entitled under the Agreement due to the use by any Wholesale Customer of more water than the amount to which it is entitled under the Agreement.

San Francisco installs such new connections between the Regional Water System and the distribution system of any Wholesale Customer that are necessary to deliver the quantities of water to which the Wholesale Customer is entitled under the Agreement. San Francisco has the right to determine the location of such connections, in light of the need to maintain the structural integrity of the Regional Water System and, where applicable, the need to limit peaking directly off of Regional Water System pipelines by a Wholesale Customer’s individual retail customers, the need to ensure that a Wholesale Customer’s individual retail customers have access to alternative sources of water in the event of a reduction in San Francisco’s ability to provide them with water, and other factors which may affect the desirability or undesirability of a particular location.

Wholesale Customer Service Areas
A Wholesale Customer may not deliver water furnished to it by San Francisco outside the boundary of its service area without the prior written consent of San Francisco, except for deliveries to another Wholesale Customer on an emergency and temporary basis. San Francisco may refuse a Wholesale Customer’s request to expand its service area on any reasonable basis.

If two or more Wholesale Customers agree to adjust the boundaries of their respective service areas so that one assumes an obligation to serve customers in an area that was previously within the service area of another Wholesale Customer, they may also correspondingly adjust their respective Individual Supply Guar antees. Such adjustments require only the consent of San Francisco and the Wholesale Customers involved, so long as the Supply Assurance and the Individual Supply Guarantees of other Wholesale Customers are not affected.

San Francisco acknowledges that it has heretofore consented in writing to deliveries of water by individual Wholesale Customers outside their service area boundaries and agrees that nothing in the Agreement is intended to affect such prior authorizations, which remain in full force and eff ect according to their terms.

Permanent Transfers of Individual Supply Guarantees and Minimum Annual Purchase Quantities A Wholesale Customer that has an Individual Supply Guarantee may transfer a portion of it to one or more other Wholesale Customers; transfers of a portion of an Individual Supply Guarantee must be permanent; and transfers of portions of Individual Supply Guarantees are subject to approval by the SFPUC. SFPUC review is limited to (1) whether a proposed transfer complies with the Act, and ( 2) whether the affected facilities in the Regional Water System have sufficient capacity to accommodate delivery of the increased amount of water to the proposed transferee.

B-7
Transfers of a portion of a Minimum Annual Purchase Quantity may be included in transfers of a portion of an Individual Supply Guarantee and are subject to the same requirements for Individual Supply Guarantee transfers as well as certain additional conditions.

Restrictions on Resale
Each Wholesale Customer agrees that it will not sell any water purchased from San Francisco to a private party for resale by such private party to others in violation of the Act.

Each Wholesale Customer also agrees that it will not sell water purchased from San Francisco to another Wholesale Customer without prior written approval of the SFPUC, except on a temporary and emergency basis. The SFPUC agrees that it will not unreasonably withhold its consent to a request by a Wholesale Customer to deliver water to another Wholesale Customer for resale.

Conservation; Use of Local Sources
Each Wholesale Customer shall take all actions within its legal authority related to water conservation that are necessary to insure that the SFPUC (a) remains eligible for (i) state and federal grants and (ii) access to the Drought Water Bank operated by the California Department of Water Resources, as well as other Drought -related water purchase or transfer programs, and (b) complies with future legal requirements imposed on the Regional Water System by the federal government, the State, or any other third party as conditions for receiving funding or water supply.

San Francisco and each Wholesale Customer agree that they will diligently apply their best efforts to use both surface water and groundwater sources located within their respective service areas and available recycled water to the maximum feasible extent, taking into account the environmental impacts, the public health effects and the effects on supply reliability of such use, as well as the cost of developing such sources .

Restrictions on Purchases of Water from Others; Minimum Annual Purchases Each Wholesale Customer (except for Alameda County Water District and the cities of Milpitas, Mountain View and Sunnyvale) agrees that it will not contract for, purchase or receive, with or without compensation, directly or indirectly, from any person, corporation, governmental agency or other entity, any water for delivery or use within its service area without the prior written consent of San Francisco.

The prohibition in the preceding sentence does not apply to:

1. recycled water;

2. water necessary on an emergency and temporary basis, provided that the Wholesale Customer promptly gives San Francisco notice of the nature of the emergency, the amount of water that has been or is to be purchased, and the expected duration of the emergency; or

3. water in excess of a Wholesale Customer’s Individual Supply Guarantee.

Alameda County Water District and the cities of Milpitas, Mountain View and Sunnyvale may purchase water from sources other than San Francisco, provided that San Francisco shall require that each purchase a minimum annual quantity of water from San Francisco. These Minimum Annual Purchase Quantities are set out in the Agreement and the Individual Water Sales Contracts between San Francisco and each of these four Wholesale Customers, and a portion of such a quantity may be transferred to another Wholesale Customer at the same time as a transfer of a portion of Individual Supply Guarantee. Certain Wholesale Customers may also be required to purchase Temporary Modified Minimum Annual Purchase Quantities from San Francisco.

B-8
Water Quality
San Francisco shall deliver treated water to Wholesale Customers (except Coastside County Water District, which receives untreated water from Crystal Springs and Pilarcitos Reservoirs) that complies with primary maximum contaminant level and treatment technique standards at the regulatory entry points designated in the San Francisco Regional Water System Domestic Water Supply Permit (currently Permit No. 02-04-04P3810001) issued by the California Department of Public Health.

Regional Water System Repair, Maintenance and Operation San Francisco will keep the Regional Water System in good working order and repair consistent with prudent utility practice.

San Francisco will continue to operate its reservoirs in a manner that assigns higher priority to the delivery of water to the Bay Area and the environment than to the generation of electric power. The SFPUC, as the Regional Water System operator, is solely responsible for making day-to-day operational decisions.

Shortages
Notwithstanding San Francisco’s obligations to deliver the Supply Assurance to the Wholesale Customers collectively and the Individual Supply Guarantees to Wholesale Customers individually, San Francisco may reduce the amount of water available or interrupt water deliveries to specific geographical areas within the Regional Water System service area to the extent that such reductions are necessary due to Emergencies, or in order to install, repair, rehabilitate, replace, investigate or inspect equipment in, or perform other maintenance work on, the Regional Water System. Such reductions or interruptions may be imposed by San Francisco without corresponding reductions or interruptions in the amount of water available to SFPUC water users outside the specific geographical area where reductions or interruptions are necessary, if the system’s ability to supply water outside the specific geographical area has not been impaired. In the event of such a reduction or interruption, San Francisco will restore the supply of water to the specific geographical area as soon as is possible.

Following a major system emergency event, the SFPUC will work closely with its Wholesale Customers to monitor customer demand, including the demand source. In the event that any individual Wholesale Service Area or Retail Service Area customer’s uncontrolled distribution system leaks could result in major water waste and endanger the supply provided by the Regional Water System as a whole, flow through some customer connections may need to be temporarily reduced or terminated. SFPUC will work closely with customers to assess the nature of the demand (e.g. fire-fighting versus leakage), so that public health and safety protection can be given top priority.

1. All emergencies that require use of non -potable source water will require use of chlorine, or other suitable disinfectant, if feasible.

2. San Francisco will use its best efforts to meet the seismic reliability and delivery reliability level of service goals adopted by the Commission in conjunction with the WSIP. San Francisco will distribute water on an equitable basis throughout the Regional Water System service area following a regional Emergency, subject to physical limitations caused by damage to the Regional Water System.

Notwithstanding San Francisco’s obligations to deliver the Supply Assurance to the Wholesale Customers collectively and the Individual Supply Guarantees to Wholesale Customers individually, San Francisco may reduce the amount of water available to the Wholesale Customers in response to Drought.

1. The Tier 1 Shortage Plan set forth in the Agreement will continue to be used to allocate water from the Regional Water System between Retail and Wholesale Customers during system-wide shortages of 20% or less.

2. San Francisco and the Wholesale Customers may negotiate in good faith revisions to the Tier 1 Shortage Plan to adjust for and accommodate anticipated changes due to demand hardening in the SFPUC’s Wholesale and Retail Service Areas. Until agreement is reached, the current Tier 1 Shortage Plan will remain in effect.

B-9

3. The SFPUC will honor allocations of water among the Wholesale Customers (“Tier 2 Allocations”) provided by BAWSCA or if unanimously agreed to by all Wholesale Customers. If BAWSCA or all Wholesale Customers do not provide the SFPUC with Tier 2 Allocations, then the SFPUC may make a final allocation decision after first meeting and discussing allocations with BAWSCA and the Wholes ale Customers. For Regional Water System shortages in excess of 20%, San Francisco shall (a) follow the Tier 1 Shortage Plan allocations up to the 20% reduction, (b) meet and discuss how to implement incremental reductions above 20% with the Wholesale Customers, and (c) make a final determination of allocations above the 20% reduction. After the SFPUC has made the final allocation decision, the Wholesale Customers shall be free to challenge the allocation on any applicable legal or equitable basis.

4. San Francisco will use its best efforts to identify potential sources of dry year water supplies and establish the contractual and other means to access and deliver those supplies in sufficient quantity to meet a goal of not more than 20% system-wide shortage in any year of the design drought.

Wheeling of Water from Outside SFPUC System
Subject to the Wheeling Statute, the SFPUC will not deny use of Regional Water System unused capacity for wheeling when such capacity is available for wheeling purposes during pe riods when the SFPUC has declared a water shortage emergency under Water Code Section 350 if the following conditions are met:

A. The transferor pays reasonable charges incurred by the SFPUC as a result of the wheeling, including capital, operation, maintenance, administrative and replacement costs (as such are defined in the Wheeling Statute).

B. Wheeled water that is stored in the Regional Water System spills first.

C. Wheeled water will not unreasonably: (1) impact fish and wildlife resources in Regional Water System reservoirs; (2) diminish the quality of water delivered for consumptive uses; or (3) increase the risk of exotic species impairing Regional Water System operations. The transferor may at its own expense provide for treatment to mitigate these effects.

D. Priority will be given to wheeling by Wholesale Customers or BAWSCA over arrangements for third-party public entities.

Limits on New Customers
Until December 31, 2028, San Francisco will not enter into contracts to supply water to any entity other than a Wholesale Customer (whether permanent or temporary, firm or interruptible) unless:

1. It completes any necessary environmental review under CEQA of the proposed new wholesale water service obligations;

2. It concurrently completes any necessary environmental review under CEQA and commits to make both San José and Santa Clara permanent customers with Individual Supply Guarantees equal to at least 9 MGD; and

3. The Agreement is amended to incorporate any commitments to proposed new wholesale customers and to San José and Santa Clara, and to address the effects, if any, of the new customer(s) on water supply reliability, water quality and cost to existing customers of the Regional Water System.

As of January 1, 2029, San Francisco will not enter into contracts to supply water to any entity other than a Wholesale Customer (whether permanent or temporary, firm or interruptible) unless:

1. It completes any necessary environmental review under CEQA of the proposed new wholesale water service obligations;

B-10

2. It concurrently completes any necessary environmental review under CEQA and commits to make both San José and Santa Clara permanent customers with Individual Supply Guarantees equal to at least 9 MGD;

3. Doing so increases the reliability of the Regional Water System; and

4. The Agreement is concurrently amended (a) to reflect that increased reliability by means of an increased commitment by San Francisco to deliver water during Droughts and (b) to address the effects, if any, of the new customer(s) on water supply, water quality and cost to existing customers of the Regional Water System.

San Francisco may enter into new retail water service obligations outside of the City and County of San Francisco:

1. Only in Alameda, San Mateo, Santa Clara, San Joaquin and Tuolumne Counties;

2. That are within or immediately adjacent to areas in which it currently serves other Retail Customers; and

3. Until the aggregate additional demand represented by the new retail customers reaches 0.5 MGD.

The limitations on serving new Retail Customers described in this subsection do not apply to historical obligations to supply water that may be contained in prior agreements between the SFPUC or its predecessor the Spring Valley Water Comp any, and individual users or property owners located adjacent to Regional Water System transmission pipelines.

Subject to completion of necessary environmental review under CEQA, San Francisco may at any time enter into water exchanges or cost sharing agreements with other water suppliers to enhance dry year or normal year water deliveries, provided that San Francisco cannot incur new water service obligations to such other water suppliers unless the requirements for taking on new wholesale customers are met.

New Sources of Water Supply to Maintain Supply Assurance Sudden and unanticipated events may require San Francisco to act promptly to protect the health, safety and economic well -being of its Retail and Wholesale Customers. Such sudden events include, but are not limited to drought, earthquakes, terrorist acts, catastrophic failures of facilities owned and operated by San Francisco, and other natural or man-made events. If such events diminish San Francisco’s ability to maintain the Supply Assurance, San Francisco may increase the Wholesale Revenue Requirement to pay for planning, evaluation and implementation of replacement sources of supply when such needs arise and without the prior approval of the Wholesale Customers.

Climate change, regulatory action s and other events may impact San Francisco’s ability to maintain the Supply Assurance from its existing surface water supplies, but on timescales long enough to permit San Francisco to collaborate with its Wholesale Customers on how best to address possible impacts to water supply. If such events diminish San Francisco’s ability to maintain the Supply Assurance, San Francisco may increase the Wholesale Revenue Requirement to pay for planning, evaluation and implementation of replacement sources of supply when such needs arise and without the prior approval of the Wholesale Customers.

New Sources of Water Supply to Increase Supply Assurance San Francisco may offer to increase the Supply Assurance at the request of some or all of its Wholesale Customers. Costs associated with providing additional water from its existing water supplies in San Mateo, Santa Clara, Alameda, Tuolumne, and Stanislaus Counties shall be allocated to Wholesale and Retail Customers as described in the Agreement.

If San Francisco seeks t o develop additional water supplies from new sources to increase the Supply Assurance available to Wholesale Customers, studies and resulting water supply projects will be conducted jointly with BAWSCA under separate agreement(s) specifying the purpose of the projects, the anticipated regional benefits

B-11
and how costs of studies and implementation will be allocated and charged. Nothing in the Agreement shall serve as precedent for the allocation of such new supply capital costs between Retail and Wholesale Customers or associated operational expenses, which shall only occur following approval of both parties and amendment of the Agreement, if necessary.

Interim Supply Limitation Imposed by SFPUC
In adopting the WSIP in Res. No. 08- 0200, the Commission included full implementation of all proposed WSIP capital improvement projects to achieve level of service goals relating to public health, seismic safety, and delivery reliability, but decided to adopt a water supply element that includes the Interim Supply Limit ation. The Interim Supply Limitation is allocated as follows between Retail and Wholesale Customers:

Retail Customers’ allocation: 81 MGD
Wholesale Customers’ allocation: 184 MGD
The Wholesale Customers’ collective allocation of 184 MGD under the Interim Supply Limitation includes the demand of the cities of San José and Santa Clara, whose demand is not included in the Supply Assurance.

Transfers of Interim Supply Allocations
Any Wholesale Customer, including Hayward, may transfer a portion of its Interim Supply Allocation to one or more other Wholesale Customers. All Wholesale Customers are also eligible transferees, including California Water Service Company up to its Individual Supply Guarantee. Transfers of a portion of an Interim Supply Allocation must be prospective. The duration of a transfer cannot be less than the balance of the fiscal year. Transfers of portions of Interim Supply Allocations are subject to approval by the SFPUC. SFPUC review is limited to determining (1) whether a proposed transfer complies with the Act, and (2) whether the affected facilities in the Regional Water System have sufficient capacity to accommodate delivery of the increased amount of water to the proposed transferee.

Maintenance of Condition of Hetch Hetchy Reservoir
San Francisco may not change the existing condition of the Hetch Hetchy Reservoir by:

1. Abandoning or decommissioning O’Shaughnessy Dam; or

2. Draining Hetch Hetchy Reservoir, except for purposes of (i) repair, rehabilitation, maintenance, improvement, or reconstruction of O’Shaughnessy Dam or appurtenances, (ii) supplying water to the Bay Area during drought, or (iii) meeting water release requirements under the Raker Act, or feder al or state law unless the parties enter into an amendment to the Water Supply Agreement.

Environmental Enhancement Surcharge
For the duration of the Interim Supply Limitation, the Commission will establish the Environmental Enhancement Surcharge concurrently with the budget- coordinated rate process set forth in the Agreement. The monetary amount of the Environmental Enhancement Surcharge per volume of water, such as dollars per acre -foot, will be equivalent for Retail Customer use in excess of 81 MGD and Wholesale Customer use in excess of 184 MGD.

The Environmental Enhancement Surcharge will be levied only if and when combined Retail Customer and Wholesale Customer purchases exceed the Interim Supply Limitation of 265 MGD and if the fund described below has been established by the San Francisco Board of Supervisors. In that event, the Environmental Enhancement Surcharge will apply to Retail Customers for use in excess of 81 MGD and to individual Wholesale Customers for use in excess of their Interim Supply Allocations established by the Commission.

1. Environmental Enhancement Surcharges related to the Retail Customers’ use in excess of their 81 MGD Retail Customer Allocation will be paid by the SFPUC, and no portion of such surcharges

B-12
may be allocated to Whole sale Customers. The method of recovering the Environmental Enhancement Surcharges imposed upon Retail Customers shall be within the sole discretion of the SFPUC.

2. Environmental Enhancement Surcharges related to the individual Wholesale Customers’ use in excess of their respective Interim Supply Allocations will be paid to the SFPUC by individual Wholesale Customers.

Environmental Enhancement Surcharges paid by the SFPUC and by Wholesale Customers will be placed into a restricted reserve fund. The SFPUC will request the San Francisco Board of Supervisors to establish this fund by ordinance and, if adopted, the fund will be subject to the following restrictions:

1. Interest earnings will stay in the reserve fund.

2. The reserve fund shall (a) be subject to automatic appropriation; (b) require unexpended and unencumbered fund balances to be carried forward from year to year; and (c) not be transferred to the San Francisco General Fund.

3. The reserve fund may be used only for specific environmental restoration and enhance ment measures for the Sierra and local watersheds, such as those included in the Watershed Environmental Improvement Program.

4. Environmental Enhancement Surcharge proceeds shall be expended in an expeditious manner. Any Environmental Enhancement Surcharge proceeds that remain in the reserve fund as of December 31, 2018 shall be used to complete projects previously approved. Upon completion of the identified projects, the balance of any unexpended sums in the reserve fund shall be distributed to BAWSCA and the SFPUC in proportion to the total amount of surcharges assessed to the Wholesale and Retail Customers, respectively.

Specific uses of Environmental Enhancement Surcharges will be decided by the SFPUC and BAWSCA General Managers following input from environmental stakeholders and other interested members of the public. If parties are unable to agree, then they will jointly select a third person to participate in making the decision.

San José/Santa Clara Interim Supply Allocation and Process for Reduction/ Termination.

San Francisco will supply a combined annual average of 9 MGD to the cities of San José and Santa Clara through 2028. Water supplied by San Francisco may only be used in the existing defined service areas in the northern portions of San José and Santa Clara. San Francisco may reduce the quantity of water specified in this section when it establishes the Interim Supply Allocations for Wholesale Customers. The establishment of Interim Supply Allocations for San José and Santa Clara shall not be con sidered a reduction of supply, provided that the Interim Supply Allocations assigned to San José and Santa Clara do not effect a reduction greater than the aggregate average reduction in Individual Supply Guarantees for Wholesale Customers that have such guarantees.

San Francisco Decisions in 2028 Regarding Future Water Supply By December 31, 2028, San Francisco will have completed any necessary CEQA review that is relevant to making San José and Santa Clara permanent customers of the Regional Water System and will decide whether or not to make San José and Santa Clara permanent customers of the Regional Water System. San Francisco will make San José and Santa Clara permanent customers only if, and to the extent that, San Francisco determines that Regional Water System long term water supplies are available. In the event that San Francisco decides to afford permanent status to San José and Santa Clara, the Agreement will be amended.

By December 31, 2028, San Francisco will have completed any necessary CEQA review and will decide how much water if any, in excess of the Supply Assurance it will supply to Wholesale Customers from the Regional Water

B-13
System to meet their projected future water demands until the year 2040, and whether to offer a corresponding increase in the Supply Assurance as a result of its determination.

Retained Discretion of SFPUC and Wholesale Customers
The Agreement contemplates discretionary actions that the SFPUC and the Wholesale Customers may choose to take in the future that could result in physical changes to the environment (“Discretionary Actions”). The Discretionary Actions include decisions to:

1. Develop additional or alternate water resources by the SFPUC or one or more Wholesale Customers;

2. Implement the physical facilities comprising the WSIP by December 30, 2021;

3. Approve wheeling proposals by Wholesale Customers;

4. Approve new wholesale customers and water exchange or cost sharing agreements with other water suppliers;

5. Provide additional water to San José and/or Santa Clara;

6. Offer permanent status to San José and/or Santa Clara;

7. Reduce or terminate supply to San José and/or Santa Clara;

8. Provide additional water to Wholesale Customers in excess of the Supply Assurance to meet their projected future water demands;

9. Offer a corresponding volumetric increase in the Supply Assurance; and

10. Implement Hetch Hetchy Water and Power projects listed in the Agreement.

Wholesale Revenue Requirement
The Agreement shall be applicable only to the water rates charged by San Francisco to the Wholesale Customers. Nothing contained in the Agreement shall limit, constrain, or in any way affect the rates which San Francisco may charge for water sold to Retail Customers or the methodology by which such rates are determined.

The Agreement sets forth the meth od by which the Wholesale Customers’ collective share of expenses incurred by the SFPUC in delivering water to them will be determined.

The Agreement implements two general principles as follows: (1) the Wholesale Customers should not pay for expenses of SFPUC operations from which they receive no benefit and (2) the Wholesale Customers should pay their share of expenses incurred by the SFPUC in delivering water to them on the basis of Proportional Annual Use unless otherwise explicitly provided in the Agreement.

To implement these general principles, the Wholesale Revenue Requirement will consist of, and be limited to the Wholesale Customers’ shares of the following categories of expense:

1. Contribution to the capital cost of Water Enterprise New Regional Assets.

2. Water Enterprise operation and maintenance expenses, including power purchased from the Hetch Hetchy Enterprise that is used in the operation of the Water Enterprise.

3. Water Enterprise administrative and general expenses.

B-14

4. Water Enterprise property taxes.

5. The Water Enterprise’s share of the Hetch Hetchy Enterprise’s operation and maintenance, administrative and general, and property tax expenses.

6. The Water Enterprise’s share of the Hetch Hetchy Enterprise’s capital cost of New Assets classified as Water-Only and the Water-Related portion of Joint Assets.

In each of these cost categories, Direct Retail Expenses will be allocated entirely to Retail Customers. Direct Wholesale Expenses will be allocated entirely to the Wholesale Customers. Regional Expenses will be allocated between Retail Customers and Wholesale Customers.

For purposes of establishing the rates to be charged Wholesale Customers, expenses will be based on the budget for, and estimates of water purchases in, the following fiscal year. For purposes of accounting, the Wholesale Revenue Requirement will be determined on the basis of actual expenses incurred and actual water use.

In addition, rates charged to Wholesale Customers may include the Wholesale Customers’ contribution to a Wholesale Revenue Coverage Reserve, which is not included in the Wholesale Revenue Requirement itself.

Capital Cost Contribution – New Regional Assets
The Wholesale Customers shall pay the wholesale share of Net Annual Debt Service for new Regional Assets.

1. The amount of Net Annual Debt Service for New Regional Assets will be determined for each series of Indebtedness issued. Until the proceeds of a particular series are Substantially Expended, the amount attributable to specific projects will be based on th e expected use of proceeds shown in the “Certificate Regarding Use of Proceeds” executed by the SFPUC General Manager on behalf of the Commission in connection with the sale of the Indebtedness.

2. After the proceeds of a series are Substantially Expended, the SFPUC General Manager will prepare and execute a certificate showing the actual expenditure of proceeds at an allocation of Net Debt Service to New Regional Assets for a series of bonds will be used in the fiscal year in which the proceeds have been Substantially Expended and thereafter.

3. The Wholesale Customers’ share of Net Annual Debt Service for the New Regional Assets that are categorized as Direct Wholesale will be 100 percent. (None of the projects in the WSIP are categorized as Direct Wholesale.) The Wholesale Customers’ share of Net Annual Debt Service for all other New Regional Assets will be determined each year and will be equal to the Wholesale Customers’ Proportional Annual Use.

4. If Indebtedness is issued by the SFPUC to refund the 2006 Revenue Bonds, Series A or to refund any other long-term Indebtedness issued after July 1, 2009, the Net Annual Debt Service attributable to proceeds used for refunding will be allocated on the same basis as the Indebtedness being refunded.

5. In addition to Net Deb t Service, Wholesale Customers will pay a proportionate share of annual administrative costs associated with Indebtedness, such as bond trustee fees, credit rating agency fees, letter of credit issuer fees, San Francisco Revenue Bond Oversight Committee fees, etc., but only to the extent such fees are neither paid from proceeds of Indebtedness nor included in SFPUC operation and maintenance or administrative and general expenses.

The Wholesale Customers shall pay the wholesale share of the appropriation contained in the SFPUC annual budget for each year to be used to acquire or construct New Regional Assets.

B-15
The Wholesale Customers’ share of the annual appropriation for revenue -funded New Regional Assets that are categorized as Direct Wholesale will be 100 percent. The Wholesale Customers’ share of the annual appropriation for all other revenue -funded New Regional Assets will be determined each year and will be equal to the Wholesale Customers’ Proportional Annual Use in each fiscal year. The amount appropriated in each fiscal year for the wholesale share of New Regional Assets shall be contributed to the Wholesale Capital Fund.

Hetch Hetchy Enterprise Expenses
There are two steps involved in determining the amount of the Wholesale Customers’ share of Hetch Hetchy Enterprise expenses.

1. The first step is to determine the Water Enterprise’s share of Hetch Hetchy Enterprise operation expenses, maintenance expenses, administrative and general expenses, and property taxes.

2. The second step is to determine the Wholesale Customers’ share of expenses allocable to the Water Enterprise.

The Water Enterprise’s share of Hetch Hetchy Enterprise expenses consist of 100 percent of Water -Only expenses and the Water-Related portion (45%) of Joint expenses.

The Wholesale Customers’ share of the sum of the Water Enterprise’s share of Hetch Hetchy Enterprise expenses shall be calculated by multiplying that dollar amount by Adjusted Proportional Annual Use.

Wholesale Customers are also allocated a share of Hetch Hetchy Enterprise capit al costs. The components of Hetch Hetchy Enterprise capital costs are as follows:

1. The Water Enterprise will be assigned 100 percent of Net Annual Debt Service attributable to acquisition and construction of New Hetch Hetchy Enterprise assets that are Water -Only and the Water-Related portion (45 percent) of Net Annual Debt Service on New Hetch Hetchy Enterprise Joint assets.

2. The Water Enterprise will be assigned 100 percent of capital expenditures from revenues for New Hetch Hetchy Enterprise assets that are Water-Only and the Water-Related portion (45 percent) of such expenditures for new Hetch Hetchy Enterprise Joint assets.

The Wholesale Customers’ share of the Net Annual Debt Service and revenue funded capital expenditures shall be calculated by multiplying that dollar amount by Adjusted Proportional Annual Use.

Additional Agreements Related to Financial Issues
The Wholesale Customers have no entitlement to any of the following sources of revenue to the SFPUC.

1. Revenues from leases or sales of SFPUC real property.

2. Revenues from other utility services such as the sale of electric power, natural gas and steam.

3. Revenues from the sale of water to customers and entities other than the Wholesale Customers.

4. Revenues earned from the investment of SFPUC funds other than funds contributed by the Wholesale Customers to the Wholesale Revenue Coverage Reserve or the Wholesale Capital Fund.

Wholesale Customers are also entitled to the benefit of earnings on proceeds of Indebtedness (through expenditure on New Regional Assets and /or application to Debt Service) and to interest on the Balancing Account.

5. Revenues not related to the sale of water.

B-16
The Wholesale Customers will not be charged with any of the following expenses:

1. Capital costs for assets constructed or acquired prior to July 1, 1984.

2. Expenses incurred by the SFPUC for generation and distribution of electric power, including Hetch Hetchy Enterprise Power -Only expenses and the Power -Related share of Hetch Hetchy Enterprise Joint expenses. An exception to this is Regional energy costs incurred by the Water Enterprise, for which Wholesale Customers are charged on the basis of Proportional Annual Use.

3. Expenses incurred by SFPUC in providing water to Retail Customers.

4. Expenses associated with the SFPUC’s accruals o r allocations for uncollectible Retail Water accounts.

5. Attorneys’ fees and costs incurred by the Wholesale Customers that a court of competent jurisdiction orders San Francisco to pay as part of a final, binding judgment against San Francisco.

6. Any expenses associated with funding any reserves (other than the required Wholesale Revenue Coverage Reserve) accrued and not anticipated to be paid within one year unless such reserve is established by mutual agreement of the SFPUC and BAWSCA.

7. Any expenses accrued in respect to pending or threatened litigation, damage or personal injury claims or other loss contingencies unless projected to be paid within one year. Otherwise, such expenses will be charged to the Wholesale Customers when actually paid.

8. Any expenses associated with installing, relocating, enlarging, removing or modifying meters and service connections at the request of an individual Wholesale Customer.

9. The Retail Customers’ portion of any Environmental Enhancement Surcharges imposed to enforce the Interim Supply Limitation.

The following payments by Wholesale Customers, individually or collectively, are not credited as Wholesale revenues.

1. Payments by individual Wholesale Customers of the Environmental Enhancement Surcharge imposed to enforce the Interim Supply Limitation.

2. Payments of attorneys’ fees and costs incurred by San Francisco that a court of competent jurisdiction orders the Wholesale Customers to pay as part of a final, binding judgment against the Wholesale Customers.

3. Payments by individual Wholesale Customers for installation, relocation, enlargement, removal or modification of meters and service connections requested by, and charged to, a Wholesale Customer.

4. Payments applied to the amortization of the ending balance in the balancing account under the 1984 Agreement.

5. Payments of the Water Management Charge which are delivered to BAWSCA.

6. Payments directed to the Wholesale Revenue Coverage Reserve.

7. Prepayments of certain capital and revenues payment.

B-17
The Wholesale Customers will receive a proporti onal benefit from funds received by the SFPUC from (a) governmental grants, rebates, reimbursements or other subventions, (b) private-sector grants for Regional capital or operating purposes of the Water Enterprise and the Water -Only and Water-related portion of Joint Hetch Hetchy Water Enterprise expenses, or (c) a SFPUC use of taxable bonds.

The Wholesale Customers will receive a proportionate benefit from recovery of damages, including liquidated damages, by SFPUC from judgments against or settlements with contractors, suppliers, sureties, etc., related to Regional Water System projects and the Water -Only and Water-Related portion of Joint Hetch Hetchy Enterprise projects.

The SFPUC will continue to charge Wholesale Customers for assets acquired or constructed with proceeds of Indebtedness on which Wholesale Customers paid Debt Service during the Term of the Agreement on the “cash” basis (as opposed to the “utility” basis) after the expiration or earlier termination of the Agreement.

Rate Adjustments
Adjustments to the rates applicable to the Wholesale Customers, other than emergency rate increases and drought rate increases, shall be coordinated with the budget development process described in the Agreement.

The Commission may adjust the Wholesale Customers’ rates in response to an Emergency that damages the Regional Water System and disrupts San Francisco’s ability to maintain normal deliveries of water to Retail and Wholesale Customers. In such an Emergency, the Commission may adopt an emergency rate surcharge applicable to Wholesale Customers without following the budgeting procedures set forth in the Agreement, provided that any such rates surcharge imposed by the Commission shall be applicable to both Retail and Wholesale Customers and incorporate the same percentage increase for all customers. Any emergency rate surcharge adopted by the Commission shall remain in effect only until the next-budget coordinated rate-setting cycle.

If the Commission declares a water shortage emergency under Water Code Section 350, implements the Tier 1 Shortage Plan and imposes drought rates on Retail Customers, it may concurrently adjust wholesale rates independently of coordination with the annual budget process. Those adjustments may be designed to encourage water conservation and may constitute changes to the structure of the rates. Drought Rate payments and payments of excess use charges levied in accordance with the Tier 1 Shortage Plan constitute Wholesale Customer Revenue and count towards the Wholesale Revenue Requirement. The SFPUC may use these revenues to purchase additional water for the Wholesale Customers from the State Drought Water Bank or other willing seller.

Rate Structure
The Agreement is not intended and shall not be construed to limit the Commission’s right (a) to adjust the structure of the rate schedule applicable to the Wholesale Customers (i.e., the relationship among the several charges set out therein) or (b) to add, delete, or change the various charges which make up the rate schedule, provided that neither such charges nor the structure of the rate schedule(s) applicable to the Wholesale Customers shall be arbitrary, unreasonable, or unjustly discriminatory as among said customers. The SFPUC will give careful consider ation to proposals for changes in the rate schedule made jointly by the Wholesale Customers but, subject to the limitations set out above, shall retain the sole and exclusive right to determine the structure of the rate schedule.

The SFPUC may recommend, and the Commission may adopt, changes in the structure of wholesale rates at any time. However, the new rate schedule implementing these changes will become effective at the beginning of the following fiscal year.

Balancing Account
After the close of each fiscal year, the SFPUC will compute the costs allocable to the Wholesale Customers for that fiscal year based on actual costs incurred by the SFPUC and actual amounts of water used by the Wholesale Customers and the Retail Customers. That amount will be compared to the amounts billed to the Wholesale Customers for that fiscal year (including any Excess Use Charges, but excluding revenues not credited to the Wholesale Revenue

B-18
Requirement). The difference will be posted to a “balancing account” as a credit to, or charge against, the Wholesale Customers. Interest shall also be posted to the balancing account calculated by multiplying the amount of the opening balance by the average net interest rate, certified by the Controller as earned in the San Francisco Treasury for the previous fiscal year on the San Francisco County Pooled Investment Account. Interest, when posted, will carry the same mathematical sign (whether positive or negative) as carried by the opening balance. The amount posted to the balancing account in each year shall be added to, or subtracted from, the balance in the account from previous years.

If the amount in the balancing account is owed to the Wholesale Customers (a positive balance), the SFPUC shall take it into consideration in establishing wholesale rates. However, the SFPUC need not apply the entire amount to reduce wholesale rates for the immediately ensuing year. Instead, the SFPUC may prorate a positive ending balance over a period of up to three successive years in order to avoid fluctuating decreases and increases in wholesale rates.

If the amount in the balancing account is owed to the SFPUC (a negative balance), the SFPUC shall not be obligated to apply all or any part of the negative balance in establishing wholesale rates for the immediately ensuring year. Instead, the SFPUC may prorate the negative balance in whole or in part over multiple years in order to avoid fluctuating increases and decreases in wholesale rates.

Wholesale Revenue Coverage Reserve
The SFPUC may include in wholesale rates for any fiscal year an additional dollar amount (“Wholesale Revenue Coverage”), which for any fiscal year shall equal the following:

1. The lesser of (i) 25% of the Wholesale Customers’ share of Net Annual Debt Service for that fiscal year, or ( ii) the amount necessary to meet the Wholesale Customers’ proportionate share of Debt Service coverage required by then-current Indebtedness for that fiscal year, minus

2. A credit for (i) the actual amount previously deposited in the “Wholesale Revenue Cover age Reserve,” (ii) accrued interest on the amounts on deposit in the Wholesale Revenue Coverage Reserve, and (iii) an amount equal to any additional interest that would have accrued on the actual amounts previously deposited in the Wholesale Revenue Coverage Reserve assuming no withdrawals had been made therefrom.

During each fiscal year, the SFPUC will set aside and deposit that portion of revenue equal to Wholesale Revenue Coverage into a separate account that the SFPUC will establish and maintain, to be known as the “Wholesale Revenue Coverage Reserve.” Deposits into the Wholesale Revenue Coverage Reserve shall be made no less frequently than monthly. The Wholesale Revenue Coverage Reserve shall be credited with interest. The SFPUC may use amounts in the Wholesale Revenue Coverage Reserve for any lawful purpose. Any balance in the Wholesale Revenue Coverage Reserve in excess of the Wholesale Revenue Coverage amount as of the end of any fiscal year shall be applied as a credit against wholesale rates in the immediately following fiscal year unless otherwise directed by BAWSCA.

If, prior to expiration of the Term, the SFPUC determines that it would be in the best financial interest of both Retail Customers and Wholesale Customers of the Regional Water System for the Debt Service coverage requirement to be increased in one or more series of proposed new Indebtedness above 125%, or for the coverage covenant to be strengthened in other ways, it will provide a written report to BAWSCA. The report will contain (1) a description of proposed covenant(s) in the bond indenture; (2) an explanation of how savings are expected to be achieved (e.g., increase in the SFPUC’s credit rating over the then-current level; ability to obtain credit enhancement, etc.); (3) the estimated all- in true interest cost savings; (4) a comparison of the Wholesale Revenue Requirements using the Debt Service coverage limitation and under the proposed methodology; and (5) a comparison of the respective monetary benefits expected to be received by both Retail and Wholesale Customers. The SFPUC and BAWSCA agree to meet and confer in good faith about the proposed changes.

Any increase in Debt Service coverage proposed by the SFPUC shall be commensurate with Proportional Water Use by Retail and Wholesale Customers. If the SFPUC demonstrates that an increase in Debt Service coverage will result in equivalent percentage reductions in total Wholesale and Retail Debt Service payments over the life of the proposed new Indebtedness, based on Proportional Wat er Use, BAWSCA may agree to a modification of the

B-19
Wholesale Revenue Coverage requirement. If BAWSCA does not agree to a proposed modification in coverage requirements in the covenants for new Indebtedness, SFPUC may nevertheless proceed with the modification and the issuance of new Indebtedness. Any Wholesale Customer, or BAWSCA, may challenge an increase in the Wholesale Revenue Requirement resulting from the modification in Debt Service coverage through arbitration. If the arbitrator finds that the increase in Debt Service coverage (1) did not and will not result in equivalent percentage reductions in total Wholesale and Retail Debt Service payments over the life of the proposed new Indebtedness, based on Proportional Water Use, or (2) was not commensurate with Proportional Water Use, the arbitrator may order the Wholesale Revenue Requirement to be recalculated both retrospectively and prospectively to eliminate the differential impact to Wholesale or Retail Customers.

Working Capital Requirement
The SFPUC maintains working capital in the form of unappropriated reserves for the purpose of bridging the gap between when the SFPUC incurs operating expenses required to provide service and when it receives revenues from its Retail and Wholesale Customers. The Who lesale Customers shall fund their share of working capital as part of the annual Wholesale Revenue Requirement calculation. The amount of wholesale working capital for which the Wholesale Customers will be responsible will be determined using the 60- day standard formula approach.

Applying this approach, annual wholesale working capital equals one -sixth of the wholesale allocation of operation and maintenance, administrative and general, and property tax expenses for the Water and Hetch Hetchy Enterprises. Wholesale working capital shall be calculated separately for the Water and Hetch Hetchy Enterprises.

Wholesale Capital Fund
The SFPUC shall establish a comparable Wholesale Revenue-Funded Capital Fund (Wholesale Capital Fund) to enable the Wholesale Customers to fund the wholesale share of revenue-funded New Regional Assets. The SFPUC may include in wholesale rates for any fiscal year an amount equal to the wholesale share of the SFPUC’s appropriation for revenue funded New Regional Assets for that year, whi ch sum will be credited to the Wholesale Capital Fund. The wholesale share of other sources of funding, where legally permitted and appropriately accounted for under GAAP, will also be credited to the Wholesale Capital Fund, together with interest earnings on the Wholesale Capital Fund balance.

The SFPUC will expend revenues appropriated and transferred to the Wholesale Capital Fund only on New Regional Assets.

In order to prevent the accumulation of an excessive unexpended and unencumbered surplus in the Wholesale Capital Fund, any excess fund balance will be transferred for the credit of the Wholesale Customers to the Balancing Account.

Arbitration and Judicial Review
All questions or disputes arising under the following subject areas shall be subject to mandatory, binding arbitration and shall not be subject to judicial determination:

1. the determination of the Wholesale Revenue Requirement, which shall include both the calculations used in the determination and the variables used in those calculations;

2. the SFPUC’s adherence to accounting practices and conduct of the compliance audit; and

3. the SFPUC’s classification of new assets for purposes of determining the Wholesale Revenue Requirement.

All other questions or disputes arising under this Agreement sha ll be subject to judicial determination.

Disputes about the scope of arbitrability shall be resolved by the courts.

B-20
Preservation of Water Rights; Notice of Water Rights Proceedings It is the intention of San Francisco to preserve all of its water rights, irrespective of whether the water held under such water rights is allocated under the Agreement. Nothing in the Agreement shall be construed as an abandonment, or evidence of an intent to abandon, any of the water rights that San Francisco presently possess es.

Reservations of, and Limitations on, Claims
The 1984 Agreement resolved a civil action brought against San Francisco by certain of the Wholesale Customers. Plaintiffs in that action contended that they, and other Wholesale Customers that are municipali ties or special districts, were “co -grantees” within the meaning of Section 8 of the Act and were entitled to certain rights, benefits and privileges by virtue of that status. San Francisco disputed those claims.

Nothing in the Agreement, or in the Individual Water Sales Contracts, shall be construed or interpreted in any way to affect the ultimate resolution of the controversy between the Parties concerning whether any of the Wholesale Customers are “co -grantees” under the Act and, if so, what rights, bene fits and privileges accrue to them by reason of that claimed status.

The following claims, which San Francisco disputes, are reserved but may not be asserted during the Term (or portions thereof, as indicated):

1. The Wholesale Customers’ claim that the Act entitles them to water at cost.

2. The Wholesale Customers’ claim that San Francisco is obligated under the Act or state law to supply them with additional water in excess of the Supply Assurance. This claim may not be asserted unless and until San Francisco decides not to meet projected water demands of Wholesale Customers in excess of the Supply Assurance.

3. The claim by San José and Santa Clara that they are entitled under the Act, or any other federal or state law, to permanent, non -interruptible status and to be charged rates identical to those charged other Wholesale Customers. This claim may not be asserted unless and until San Francisco notifies San José or Santa Clara that it intends to interrupt or terminate water deliveries.

4. The Wholesale Customers’ claim that the SFPUC is not entitled to impose a surcharge for lost power generation revenues attributable to furnishing water in excess of the Supply Assurance. This claim may not be asserted unless and until SFPUC furnishes water in excess of the Supply Ass urance during the Term and also includes such a surcharge in the price of such water.

5. Claims by Wholesale Customers (other than San José and Santa Clara, whose service areas are fixed) that SFPUC is obligated under the Act or state law to furnish water, within their Individual Supply Guarantee, for delivery to customers outside their existing service area and that Wholesale Customers are entitled to enlarge their service areas to supply those customers. Such claims may be asserted only after SFPUC’s denial of, or failure for six months to act on, a written request by a Wholesale Customer to expand its service area.

The Wholesale Customers (and the SFPUC, where specified) will refrain from the following activities during the Term (or portions thereof, as specified):

1. The Wholesale Customers and the SFPUC will not contend before any court, administrative agency or legislative body or committee that the methodology for determining the Wholesale Revenue Requirement (or the requirements for (a) amortization of the ending balance under the 1984 Agreement, or (b) contribution to the Wholesale Revenue Coverage) determined in accordance with the Agreement violates the Act or any other provision of federal law, state law, or San Francisco’s City Charter, or is unfair, unreasonable or unlawful.

B-21

2. The Wholesale Customers will not challenge the transfer of funds by the SFPUC to any other San Francisco City department or fund, provided such transfer complies with the San Francisco City Charter. The transfer of its funds, whether or not permitted by the City Charter, will not excuse the SFPUC from its failure to perform any obligation imposed by the Agreement.

3. The Wholesale Customers and the SFPUC will not assert monetary claims against one another based on the 1984 Agreement other than otherwise arbitral claims arising from the three fiscal years immediately preceding the start of the Term (i.e., Fiscal Years 2006-07, 2007-08 and 2008-09).

The Wholesale Customers do not, by executing the Agreement, concede the legality of the SFP UC’s establishing Interim Supply Allocations or imposing Environmental Enhancement Surcharges on water use in excess of such allocations. Any Wholesale Customer may challenge such allocation when imposed and/or such surcharges if and when levied, in any court of competent jurisdiction.

The furnishing of water in excess of the Supply Assurance by San Francisco to the Wholesale Customers shall not be deemed or construed to be a waiver by San Francisco of its claim that it has no obligation under any provision of law to supply such water to the Wholesale Customers, nor shall it constitute a dedication by San Francisco to the Wholesale Customers of such water.

Prohibition of Assignment
The Agreement shall be binding on, and shall inure to the benefit of, the Wholesale Customers and San Francisco, and their respective successors and permitted assigns. Each Wholesale Customer agrees that it will not transfer or assign any rights or privileges under the Agreement, either in whole or in part, or make any transfer of all or any part of its water system or allow the use thereof in any manner whereby any provision of the Agreement will not continue to be binding on it, its assignee or transferee, or such use of the system. Any assignment or transfer in violation of this covenant, and any assignment or transfer that would result in the supply of water in violation of the Act, shall be void.

Nothing shall prevent any Wholesale Customer (except the California Water Service Company and Stanford) from entering into a joint powers agreement or a municipal or multi -party water district with any other Wholesale Customer (except the two listed above) to exercise the rights and obligations granted to and imposed upon the Wholesale Customers hereunder, nor shall this section prevent any Wholesale Customer (except the two listed above) from succeeding to the rights and obligations of another Wholesale Customer hereunder as long as the Wholesale Service Area served by the Wholesale Customers involved in the succession is not thereby enlarged.

(a) If the amendment or waiver relates to the provisions of Sections 3(a), 3(b), 4 or 5(a), it may only be made in connection with a change in circumstances that arises from a change in legal requirements, change in law, or change in the identity, nature or status of an obligated person with respect to the 2023AB Bonds or the type of business conducted;
(b) The undertaking, as amended or taking into account such waiver, would, in the opinion of the City Attorney or nationally recognized bond counsel, have complied with the requirements of the Rule at the time of the original issuance of the 2023AB Bonds, after taking into account any amendments or interpretations of the Rule, as well as any change in circumstances; and (c) The amendment or waiver either (i) is approved by the owners of a majority in aggregate principal amount of the 2023AB Bonds or (ii) does not, in the opinion of the City Attorney or nationally recognized bond counsel, materially impair the interests of the Holders.

SECTION 10. Default.

Failure by the SFPUC to comply with any provision of this Disclosure Certificate shall not be deemed an Event of Default under the Indenture and the s ole remedy under this Disclosure Certificate in the event of any failure of the SFPUC to comply with this Disclosure Certificate shall be an action to compel performance.

SECTION 11. Beneficiaries. This Disclosure Certificate shall inure solely to the bene fit of the SFPUC, the Dissemination Agent, the Participating Underwriters and Holders and Beneficial Owners from time to time of the 2023AB Bonds, and shall create no rights in any other person or entity.

APPENDIX F

SECURITIES DEPOSITORY AND THE BOOK-ENTRY SYSTEM
The information in this Appendix F has been obtained from DTC for use in securities offering documents, and the SFPUC takes no responsibility for the accuracy or completeness thereof. The SFPUC cannot and does not give any assurances that DTC, DTC Participants or Indirect Participants will distribute to the beneficial owners either (a) payments of interest, principal or premium, if any, with respect to the 2023AB Bonds or (b) certificates representing ownership interest in or other confirmation of ownershi p interest in the 2023AB Bonds, or that they will so do on a timely basis or that DTC, DTC Participants or DTC Indirect Participants will act in the manner described in this Official Statement. 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.

As used in this Appendix F, “Securities” means the 2023AB Bonds, “Issuer” means the SFPUC, and “Agent” means the Trustee.

1. The Depository Trust Company (“DTC”), New York, NY, will act as securities depository for the securities (the “Securities”). The Securities 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 Security certificate will be issued for each issue of the Securities, each 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 amo unt of such issue.

2. DTC, the world’s largest securities depository, is a limited-purpose trust company organized under the New York Banking Law, a “banking organization” within the meaning of the New York Banking Law, a member of the Federal Reserve System, a “clearing corporation” within the meaning of the New York Uniform Commercial Code, and a “clearing agency” registered pursuant to the provisions of Section 17A of the Securities Exchange Act of 1934. DTC holds and provides asset servicing for over 3.5 million issues of U.S. and non-U.S. equity issues, corporate and municipal debt issues, and money market instruments (from over 100 countries) that DTC’s participants (“Direct Participants”) deposit with DTC. DTC also facilitates the post- trade settlement among Direct Participants of sales and other securities transactions in deposited securities, through electronic computerized book- entry transfers and pledges between Direct Participants’ accounts. This eliminates the need for physical movement of securi ties certificates. Direct Participants include both U.S. and non-U.S. securities brokers and dealers, banks, trust companies, clearing corporations, and certain other organizations. DTC is a wholly-owned subsidiary of The Depository Trust & Clearing Corporation (“DTCC”). DTCC is the holding company for DTC, National Securities Clearing Corporation and Fixed Income Clearing Corporation, all of which are registered clearing agencies. DTCC is owned by the users of its regulated subsidiaries. Access to the DTC system is also available to others such as both U.S. and non -U.S. securities brokers and dealers, banks, trust companies, and clearing corporations that clear through or maintain a custodial relationship with a Direct Participant, either directly or indirectly (“Indirect Participants”). DTC has a Standard & Poor’s rating of AA+. The DTC Rules applicable to its Participants are on file with the Securities and Exchange Commission. More information about DTC can be found at www.dtcc.com. The information contained on this Internet site is not incorporated herein by reference.

3. Purchases of Securities under the DTC system must be made by or through Direct Participants, which will receive a credit for the Securities on DTC’s records. The ownership interest of each actual purchaser of each Security (“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 Securities 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 Securities, except in the event that use of the book -entry system for the Securities is discontinued.

F-2

4. To facilitate subsequent transfers, all Securities 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 Securities with DTC and their registration in the name of Cede & Co. or such other DTC nominee do not effect any change in beneficial ownership. DTC has no knowledge of the actual Beneficial Owners of the Securities; DTC’s records reflect only the identity of the Direct Participants to whose accounts such Securities 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 Securities may wish to take certain steps to augment the transmission to them of notices of significant events with respect to the Securities, such as redemptions, tenders, defaults, and proposed amendments to the Security documents. For example, Beneficial Owners of Securities may wish to ascertain that the nominee holding the Securities 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 notices be provided directly to them.

6. Redemption notices shall be sent to DTC. If less than all of the Securities within an issue are being redeemed, DTC’s practice is to determine by lot the amount of the interest of each Direct Participant in such issue to be redeemed.

7. Neither DTC nor Cede & Co. (nor any other DTC nominee) will consent or vote with respect to Securities unless authorized by a Direct Participant in accordance with DTC’s MMI 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 Securities are credited on the record date (identified in a listing attached to the Omnibus Proxy).

8. Redemption proceeds, distributions, and dividend payments on the Securities 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, 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 depository with respect to the Securities at any time by giving reasonable notice to Issuer or Agent. Under such circumstances, in the event that a successor 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.

The information in this section concerning DTC and DTC’s book- entry system has been obtained from sources that SFPUC believes to be reliable, but the SFPUC takes no responsibility for the accuracy thereof.

Any funds remaining in the Rebate Fund after redemption and payment of all of the 2023 Sub-Series A Bonds and payment and satisfaction of any Rebate Requirement shall be withdrawn and remitted to the Commission upon the Commission’s written request.

ax Covenants.

The Commission covenants that it will not take any action, or fail to take any action, if any such action or failure to take action would adversely affect the exclusion from gross income of the interest on the 2023 Sub-Series A Bonds under Section 103 of the Code.

The Commission will not directly or indirectly use or permit the use of any proceeds of the 2023 Sub-Series A Bonds or any other funds of the Commission, or take or omit to take any action that would cause the 2023 Sub- Series A Bonds to be “ arbitrage bonds” within the meaning of Section 148(a) of the Code. To that end, the Commission will comply with all requirements of Section 148 of the Code to the extent applicable to the 2023 Sub- Series A Bonds. If at any time the Commission is of the opinion that for purposes of this Section it is necessary to restrict or limit the yield on the investment of any moneys held by the Trustee under the Indenture or otherwise, the Commission shall so instruct the Trustee in writing, and the Trustee shall take such action a s required by such instructions.

Without limiting the generality of the foregoing, the Commission agrees that there shall be paid from time to time all amounts required to be rebated to the United States pursuant to Section 148(f) of the Code and any temporary, proposed or final Treasury Regulations as may be applied to the 2023 Sub-Series A Bonds from time to time. This covenant shall survive payment in full or defeasance of the 2023 Sub-Series A Bonds. The Commission specifically covenants to pay or cau se to be paid to the United States, at the times and in the amounts determined under Section 186.09 hereof, the Rebate Requirement. The Trustee agrees to comply with all written instructions of the Commission given in accordance with the Tax Certificate.

Notwithstanding any provision of this Section and Section 186.09 hereof, if the Commission provides to the Trustee an opinion of nationally recognized bond counsel to the effect that any action required under this Section and Section 186.09 hereof or under the Tax Certificate is no longer required, or to the effect that some further action is required, to maintain the exclusion from gross income of the interest on the 2023 Sub-Series A Bonds under Section 103 of the Code, 133887113.5 14
the Commission and the Trustee may rely conclusively on such opinion in complying with the provisions hereof, and the covenants hereunder shall be deemed to be modified to that extent.

The Commission shall assure that the proceeds of the 2023 Sub-Series A Bonds are not so used as to cause the 2023 Sub-Series A Bonds to satisfy the private business tests of Section 141(b) of the Code or the private loan financing test of Section 141(c) of the Code.

The Commission shall not take any action or permit or suffer any action to be taken if the result of the same would be to cause any of the 2023 Sub- Series A Bonds to be “ federally guaranteed” within the meaning of Section 149(b) of the Code.

SECTION 186.11 C ontinuing Disclosure.

The Commission hereby covenants and agrees that it will comply with and carry out all of the provisions of that certain Continuing Disclosure Certificate, dated as of the date of issuance of the 2023 Sub-Series A Bonds, executed and delivered by the Commission in connection with the issuance of the 2023 Sub-Series A Bonds, as it may be supplemented and amended in accordance with its terms (the “ 2023 Series AB Continuing Disclosure Certificate”). Notwithstanding any other provision of the Indenture, failure of the Commission to comply with the 2023 Series AB Continuing Disclosure Certificate shall not be considered an Event of Default; however, any Participating Underwriter (as such term is defined in the 2023 Series AB Continuing Disclosure Certificate) or any Bondowner or beneficial owner may take such actions as may be necessary and appropriate, including seeking specific performance by court order, to cause the Commission to comply with its obligations under this Section, and the sole remedy in the event of any failure of the Commission to comply with the 2023 Series AB Continuing Disclosure Certificate shall be an action to compel performance.

AMENDMENTS TO INDENTURE
SECTION 187.01 Effectiveness of Amendments under this Article .

In accordance with Section 9.01 of the Indenture, the amendments to the Indenture set forth in this Article CLXXXVII shall become effective at such time as the written consents of the Owners of a majority in aggregate amount of the Bond Obligation of the Bonds then Outstanding and of each Credit Provider have been filed with the Trustee, and the other requirements contained in Article IX of the Indenture have been satisfied. Until such time as the amendments to the Indenture set forth in this Article CLXXXVII become effective the app licable provisions of the Indenture shall remain unaltered and in full force and effect except as he Indenture may be otherwise amended in accordance with Article IX or discharged in accordance with Article X of the Indenture.

The provisions of the amendments to the Indenture set forth in this Article CLXXXVII are severable. Nothing herein shall preclude one or more of the provisions of this amendment, with the approval required by the Indenture, from becoming effective prior to the effective date of any 133887113.5 15
other provision. The Commission shall promptly inform the Trustee and the Bondholders in the event that consent has been secured for one or more of the provisions of this Article CLXXXVII.

SECTION 187.02 A mendments to Section 1.01 of the Indenture and Definitions.

Upon the effectiveness of the amendments in this Article CLXXXVII : (i) there shall be added to the Indenture the definition of “Excluded Principal,” “Qualified Municipal Advisor” and “SIFMA” having the definitions set forth below; (ii) all references to the term “Parity State Loans” in the Indenture shall be deemed to refer to “Parity Loans” and shall have the definition set forth below; and (iii) the definitions of “Annual Debt Service,” “Average Annual Debt Service,” “Bondowner,” “Owner” and “Maximum Annual Debt Service” in the Indenture shall be replaced by the definitions of such terms set forth below.

Bondowner, Owner
The term “Bondowner” or “Owner” means any person who is the registered owner of any Outstanding Bond, or, if such Outstanding Bond has a maturity of one year or less and is issued in bearer form, means the bearer of such Bond, or, with respect to any Parity Loan, means the State of California (or any board, department or agency thereof) or the federal government (or any board, department or agency thereof), as applicable.

Excluded Principal
“Excluded Principal” means each payment of principal of Bonds with a remaining term, on the date of calculation, of not greater than 60 months and which the Commission specifies in a Certificate of the Commission and filed with the Trustee that the Commission intends to pay from the proceeds of Bonds or Parity Loans, other bonds, notes or other obligations of the Commission or moneys other than Revenues. No such determination shall affect the security for the Bonds or Parity Loans or the obligation of the Commission to pay the Bonds and Parity Loans from Revenues.

Maximum Annual Debt Service, Annual Debt Service, Debt Service, Average Annual Debt Service
The term “ Maximum Annual Debt Service ” means, at any point in time, with respect to Bonds then Outstanding, the maximum amount of principal and interest becoming due in the then current or any future Fiscal Year, calculated by the Commission as provided in this definition. For purposes of calculating Maximum Annual Debt Service, the following assumptions are to be used to calculate the principal and interest becoming due in any Fiscal Year:
(i) in determining the principal amount due in each year, payment will (unless a different subsection of this definition applies for purposes of determining principal maturities or amortization) be assumed to be made in accordance with any amortization schedule established for such debt, including any Minimum Sinking Fund Account Payments or any scheduled redemption or payment of Bonds on the basis of Accreted Value, and for such purpose, the redemption payment or payment of Accreted Value will be deemed a principal payment and interest that is compounded and paid as Accreted Value 133887113.5 16
will be deemed due on the scheduled redemption or payment date of such Capital Appreciation Bond, but excluding Excluded Principal;
(ii) if any of the Outstanding Series of Bonds constitute Balloon Indebtedness or Balloon Indebtedness and Variable Rate Indebtedness or if Bonds then proposed to be issued would constitute Balloon Indebtedness or Balloon Indebtedness and Variable Rate Indebtedness, then, for purposes of determining Maximum Annual Debt Service, such Bonds the principal of which the Commission has not specified as Excluded Principal will be amortized for a period specified by the Commission (but no longer than forty (40) years from the date of the issuance of the Bonds to which such Balloon Indebtedness relates) on a substantially level debt service basis or other amortization basis designated by the Commission, calculated based on a fixed rate equal to the rate at which the Commission could borrow for such period, as certified by a Qualified Municipal Advisor; (iii) if any Outstanding Bonds constitute Tender Indebtedness or if Bonds then proposed to be issued would constitute Tender Indebtedness, then for purposes of determining the amounts of principal and interest due in any Fiscal Year on such Bonds, the options or obligations of the owners of such Bonds to tender the same for purchase or payment prior to their stated maturity or maturities will be treated as a principal maturity occurring on the first date on which owners of such Bonds may or are required to tender such Bonds except that any such option or obligation to tender Bonds will be ignored and not treated as a principal maturity, if (1) such Bonds are rated in one of the two highest long-term rating categories (without reference to gradations such as “plus” or “minus”) by Moody’s and by S&P or such Bonds are rated in the highest short-term, note or commercial paper rating categories by Moody’ s and by S&P and (2) the obligation, if any, the Commission may have under a Letter of Credit Agreement with respect to such Bonds, other than its obligations on such Bonds, will either be subordinated to the obligation of the Commission on the Bonds or be incurred under the conditions and meeting the tests for the issuance of Additional Bonds set forth in the Indenture; (iv) If any Outstanding Bonds constitute Variable Rate Indebtednes s, the interest rate shall, as of the date of calculation, be: (i) the greater of (a) the average SIFMA rate over the past 3 years times 150% or (b) 4 percent or (ii) if, designated in writing by the Commission in the Supplemental Indenture authorizing such Bonds (which the Commission must certify, in the case of obligations interest on which is not excluded from gross income for federal income tax purposes under the Code), a fixed rate of interest reasonably determined by the Commission for obligations with similar duration, which interest rate has been certified by a Qualified Municipal Advisor as reasonable concurrent with the execution and delivery of such Supplemental Indenture; (v) if Bonds proposed to be issued will be Variable Rate Indebtedness, then such Bonds will be assumed to bear interest at : (i) the greater of (a) the average SIFMA rate over the past 3 years times 150% or (b) 4 percent or (ii) if, designated in writing by the Commission in the Supplemental Indenture authorizing such Bonds (which the Commission must certify, in the case of obligations interest on which is not excluded from gross income for federal income tax purposes under the Code), a fixed rate of interest reasonably determined by the Commission for obligations with similar duration, which 133887113.5 17
interest rate has been certified by a Qualified Municipal Advisor as reasonable concurrent with the execution and delivery of such Supplemental Indenture; (vi) if moneys or Federal Securities or general obligation bonds of the State of California have been deposited with and are held by the Trustee or another fiduciary to be used to pay principal and/or interest on specified Bonds, then the principal and/or interest to be paid from such moneys or Federal Securities or general obligation bonds of the State of California or from the earnings thereon will be disregarded and not included in calculating Maximum Annual Debt Service.

The term “Annual Debt Service” means the sum of such principal and interest as computed for the twelve-month period ending June 30 to which reference is made.

The term “Debt Service” means the sum of all such principal and interest.

The term “Average Annual Debt Service” means total Debt Service, divided by the number of twelve-month periods ending on June 30 (including any fractional periods) remaining until the last maturity date of any Outstanding Bond.

For the purpose of calculating Maximum Annual Debt Service, Annual Debt Service, Debt Service, and Average Annual Debt Service, in determining the amount of interest coming due during any twelve-month period ending June 30 on any Series of Bonds that were issued as Build America Bonds, such amount will be reduced by an amount equal to the Refundable Credits the Commission is scheduled to receive during each such twelve-month period ending June 30. If the amount of Refundable Credits scheduled to be received by the Commission for any Series of Bonds that were issued as Build America Bonds is reduced or otherwise not received during any twelve- month period ending June 30, the Commission will calculate the amount of interest due on such Series of Bonds for the subsequent twelve month period ending June 30 by offsetting against the gross amount of interest payable on such Series only the amount of the Refundable Credits scheduled to be received under Federal legislation (or other Federal regulation, pronouncement or action) authorizing the reduction of Refundable Credits.

Parity Loans
“Parity Loans” means those loan agreements entered into between the Commission and the State of California (or any board, department or agency thereof) or the federal government (or any board, department or agency thereof) to finance additions, betterments, extensions, repairs, renewals or replacements to the Enterprise, which are entered into after the issuance of the Bonds and which, by their terms, are secured by a pledge and lien on Revenues on a parity basis with debt service on the Bonds. Parity Loans may be evidenced by or secured by Bonds.

Qualified Municipal Advisor
“Qualified Municipal Advisor” means a person or a firm selected by the Commission who or which engages in the business of advising the management of public agencies similar to the Commission concerning the issuance of debt.
133887113.5 18
SIFMA
“SIFMA” means, as of any date, the most recent rate determined on the basis of the seven- day high grade market index of tax -exempt variable rate demand obligations, as calculated and published by Bloomberg and made available by the Securities Industry and Financial Markets Association on its SIFMA Municipal Swap Index, or if the SIFMA Municipal Swap Index is no longer published or reported, the rate per annum published or reported on the S&P Municipal Bond 7 Day High Grade Rate Index, or if neither the SIFMA Municipal Swap Index nor the S&P Municipal Bond 7 Day High Grade Rate Index is published, a per annum rate equal to 60% of the yield of the three-month U.S. Treasury bill as reported as of the end of each trading day.

SECTION 191.10 Tax Covenants.

The Commission covenants that it will not take any action, or fail to take any action, if any such action or failure to take action would adversely affect the exclusion from gross income of the interest on the 2023 Sub-Series B Bonds under Section 103 of the Code.

The Commission will not directly or indirectly use or permit the use of any proceeds of the 2023 Sub-Series B Bonds or any other funds of the Commission, or take or omit to take any action that would cause the 2023 Sub- Series B Bonds to be “ arbitrage bonds” within the meaning of Section 148(a) of the Code. To that end, the Commission will comply with all requirements of Section 148 of the Code to the extent applicable to the 2023 Sub- Series B Bonds. If at any time the Commission is of the opinion that for purposes of this Section it is necessary to restrict or limit the yield on the investment of any moneys held by the Trustee under the Indenture or otherwise, the Commission shall so instruct the Trustee in writing, and the Trustee shall take such action as required by such instructions.

Without limiting the generality of the foregoing, the Commission agrees that there shall be paid from time to time all amounts required to be rebated to the United States pursuant to Section 148(f) of the Code and any temporary, proposed or final Treasury Regulations as may be applied to the 2023 Sub-Series B Bonds from time to time. This covenant shall survive payment in full or defeasance of the 2023 Sub-Series B Bonds. The Commission specifically covenants to pay or cause to be paid to the United States, at the times and in the amounts determined under Section 191.09 hereof, the Rebate Requirement. The Trustee agrees to comply with all written instructions of the Commission given in accordance with the Tax Certificate.

Notwithstanding any provision of this Section and Section 191.09 hereof, if the Commission provides to the Trustee an opinion of nationally recognized bond counsel to the effect that any action required under this Section and Section 191.09 hereof or under the Tax Certificate is no longer required, or to the effect that some further action is required, to maintain the exclusion from gross income of the interest on the 2023 Sub-Series B Bonds under Section 103 of the Code, 134830285.4 14
the Commission and the Trustee may rely conclusively on such opinion in complying with the provisions hereof, and the covenants hereunder shall be deemed to be modified to that extent.

The Commission shall assure that the proceeds of the 2023 Sub-Series B Bonds are not so used as to cause the 2023 Sub-Series B Bonds to satisfy the private business tests of Section 141(b) of the Code or the private loan financing test of Section 141(c) of the Code.

3760032.6 046549 AGMT
(b) The Underwriters shall comply with the San Francisco Business Tax Ordinance and shall, if not otherwise exempt from such ordinance, provide to the Commission a Business Tax Registration Certificate on or prior to the date hereof. (c) The Underwriters shall comply with all SEC and MSRB rules applicable to the offering, sale and delivery of the Bonds to ultimate purchasers.

Section 8.

Establishment of “Issue Price” of Bonds.
(a) The Representative, on behalf of the Underwriters, agrees to assist the Commission in establishing the “issue price” of the Bonds and shall execute and deliver to the Commission on or before the Closing Date an “issue price” or similar certificate, together with supporting pricing wires or equivalent communications, substantially in the form attached hereto as Appendix C, with such modifications as may be appropriate or necessary, in the reasonable judgment of the Representative, the Commission and Bond Counsel, to accurately reflect, as applicable, the sales price or prices or the initial offering price or prices to the public of the Bonds. All actions to be taken by the Commission under this Section 8 to establish the issue price of the Bonds may be taken on behalf of the Commission by the Commission’s Co- Municipal Advisors identified herein and any notice or report to be provided to the Commission may be provided to the Commission’s Co-Municipal Advisors. (b) With respect to Bonds of those maturities as to which at least 10% of the Bonds of the maturity has been sold to the public (defined in subsection (f) below) at a single price (the “10% test”), based on reporting by the Representative to the Commission on the date hereof and prior to the execution of this Purchase Contract, which maturities are indicated in Schedule I attached hereto as having satisfied the 10% test (the “10% Test Maturities”), the Commission will treat the first price at which 10% of each such maturity of the Bonds was sold to the public as the issue price of that maturity. With respect to Bonds of those maturities as to which the 10% test has not been satisfied, based on reporting by the Representative to the Commission on the date hereof and prior to the execution of this Purchase Contract, which maturities are indicated in Schedule I attached hereto as being subject to the “hold-the-offering- price rule,” defined below (the “Hold-the-Offering-Price Maturities”), the Representative and the Commission agree that the rules in paragraph (c) below shall apply. For purposes of this section, for Bonds maturing on the same date but having different interest rates, each separate CUSIP number for such Bonds is subject to the 10% test or subsection (c) below, as the case may be, as if such separate CUSIP number were a separate maturity. (c) With respect to the Hold -the-Offering-Price Maturities, the Representative confirms that the Underwriters have offered the Bonds to the public on or before the date of this Purchase Contrac t at the offering price or prices (the “initial offering price”), or at the corresponding yield or yields, set forth in Schedule I attached hereto, except as otherwise set -9-
3760032.6 046549 AGMT
forth therein. Schedule I also sets forth, as of the date of this Purchase Contract, the maturities, if any, of the Bonds for which the 10% test has not been satisfied and for which the Commission and the Representative, on behalf of the Underwriters, agrees that the restrictions set forth in the next sentence shall apply (the “hold-the-offering-price rule”). So long as the hold-the-offering- price rule remains applicable to any maturity of the Bonds, the Underwriters will neither offer nor sell unsold Bonds of that maturity to any person at a price that is higher than the initial offering price to the public during the period starting on the sale date and ending on the earlier of the following:
(i) the close of the fifth (5
th) business day after the sale date; or
(ii) the date on which the Underwriters have sold at least 10% of that maturity of the Bonds to the public at a price that is no higher than the initial offering price to the public.
(d) The Commission acknowledges that, in making the representations set forth in this subsection (d), the Representative will rely on (i) the agreement of each Underwriter to comply with the requirements for establishing issue price of the Bonds, including, but not limited to, its agreement to comply with the hold -the-offering-price rule, if applicable to the Bonds, as set forth in an agreement among underwriters and the related pricing wires, (ii) in the event a selling group has been created in connection with the initial sale of the Bonds to the public, the agreement of each dealer who is a member of the selling group to comply with the requirements for es tablishing issue price of the Bonds, including, but not limited to, its agreement to comply with the hold- the-offering-price rule, if applicable to the Bonds, as set forth in a selling group agreement and the related pricing wires, and (iii) in the event that an Underwriter is a party to a retail or other third-party distribution agreement that was employed in connection with the initial sale of the Bonds to the public, the agreement of each broker- dealer that is a party to such agreement to comply with the requirements for establishing issue price of the Bonds, including, but not limited to, its agreement to comply with the hold- the- offering-price rule, as set forth in the retail or other third-party distribution agreement and the related pricing wires. The Commission further acknowledges that each Underwriter shall be solely liable for its failure to comply with its agreement regarding the requirement for establishing issue price of the Bonds, including, but not limited to, its agreement to comply with the hold-the-offering-price rule, if applicable to the Bonds, and that no Underwriter shall be liable for the failure of any other Underwriter, or of any dealer who is a member of a selling group, or of any broker -dealer that is a party to a retail or other third -party distribution agreement, to comply with its corresponding agreement to comply with the requirements for establishing issue price of the Bonds, including, but not limited to, its agreement to comply with the hold-the-offering-price rule, if applicable to the Bonds. (e) The Representative confirms that:
(i) any agreement among underwriters, any selling group agreement and each retail or other third-party distribution agreement (to which the Representative is a party) relating to the initial sale of the Bonds to the public, together with the related pricing wires, contains or will contain language obligating each Underwriter, each dealer who is a member of the selling group and each broker-dealer that is a party to such retail or other third- party distribution agreement, as applicable:
-10-
3760032.6 046549 AGMT
(A) to promptly notify the Representative of any sales of Bonds that, to its knowledge, are made to a purchaser who is a related party to an underwriter participating in the initial sale of the Bonds to the public (each such term being used as defined below); and (B) to acknowledge that, unless otherwise advised by the Underwriter, dealer or broker-dealer, the Representative shall assume that each order submitted by the Underwriter, dealer or broker-dealer is a sale to the public.
(ii) any agreement among underwriters and any selling group agreement relating to the initial sale of the Bonds to the public, together with the related pricing wires, contains or will contain language obligating each Underwriter or dealer that is a party to a retail or other third-party distribution agreement to be employed in connection with the initial sale of the Bonds to the public to require each broker-dealer that is a party to such retail or other third-party distribution agreement to comply with the hold-the-offering-price rule, if applicable, in each case if and for so long as directed by the Representative or the Underwriter and as set forth in the related pricing wires. (f) The Underwriters acknowledge that sales of any Bonds to any person that is a related party to an underwriter participating in the initial sale of the Bonds to the public (each such term being used as defined below) shall not constitute sales to the public for purposes of this subsection (f). Further, for purposes of this subsection (f):
(i) “public” means any person other than an underwriter or a related party to an underwriter,
(ii) “underwriter” means (A) any person that agrees pursuant to a written contract with the Commission (or with the lead underwriter to form an underwriting syndicate) to participate in the initial sale of the Bonds to the public and (B) any person that agrees pursuant to a written contract directly or indirectly with a person described in clause (A) to participate in the initial sale of the Bonds to the public (including a member of a selling group or a party to a retail or other third- party distribution agreement participating in the initial sale of the Bonds to the public),
(iii) a purchaser of any of the Bonds is a “related party” to an underwriter i f the underwriter and the purchaser are subject, directly or indirectly, to (i) more than 50% common ownership of the voting power or the total value of their stock, if both entities are corporations (including direct ownership by one corporation of another), (ii) more than 50% common ownership of their capital interests or profits interests, if both entities are partnerships (including direct ownership by one partnership of another), or (iii) more than 50% common ownership of the value of the outstanding stock of the corporation or the capital interests or profit interests of the partnership, as applicable, if one entity is a corporation and the other entity is a partnership (including direct ownership of the applicable stock or interests by one entity of the other), and
-11-
3760032.6 046549 AGMT
(iv) “sale date” means the date of execution of this Purchase Contract by all parties.

Section 10. Good Faith Deposit. To secure the Commission from any loss resulting from the failure of the Underwriters to accept delivery of and pay the purchase price for the Bonds pursuant to the terms of this Purchase Contract, the Underwriters agree to deliver to or to the order of the Commission, concurrently with the execution and delivery of this Purchase Contract, either an official bank check (which may be deposited by the Commission upon receipt) or a federal funds wire transfer in the amount of $[Good Faith Deposit] (the “ Good Faith Deposit”). At the Closing, the Good Faith Deposit will be applied towards and deducted from the aggregate net purchase price for the Bonds as provided in Section 1 of this Purchase Contract. If the Underwriters fail to pay the purchase price in full upon tender of the Bonds (other than for a reason permitted under Section 9 hereof), the Commission may retain such Good Faith Deposit as and for liquidated damages for such failure by the Underwriters. In such circumstance, the Underwriters will have no right to recover the Good Faith Deposit or to any allowance or credit therefor.

Retaining the Good Faith Deposit shall constitute the Commission’s sole and exclusive remedy and full liquidated damages for the Underwriters’ failure (other than for a reason expressly set forth herein) to purchase and accept delivery of the Bonds pursuant to the terms of this Purchase Contract and the Underwriters shall be released and discharged from any and all claims for damages by the Commission against the Underwriters related to such failure and any other defaults by Underwriters hereunder. Accordingly, the Underwriters hereby waive any right to claim that the actual damages of the Commission are less than the Good Faith Deposit, and the acceptance of this offer by the Commission shall constitute a waiver of any right the Commission may have to additional damages from the Underwriters. The Underwriters and the Commission hereby acknowledge and agree that the amount fixed pursuant to this Section for liquidated damages does not constitute a penalty and is a reasonable estimate of the damages that the Commission would sustain in the event of the Underwriter’s failure to purchase and to accept delivery of the Bonds -18-
3760032.6 046549 AGMT
on the Closing Date pursuant to the terms of this Purchase Contract. Said amount is agreed upon and fixed as liquidated damages because of the difficulty of ascertaining as of the date hereof the actual amount of damages that would be sustained in such event. If the Commission fails to deliver the Bonds on the Closing Date pursuant to this Purchase Contract, or if the conditions to the obligations of the Underwriters to purchase, accept delivery of and pay for the Bonds as set forth in this Purchase Contract shall not be satisfied (unless waived in writing by the Representative pursuant to this Purchase Contract), or if this Purchase Contract is terminated for a reason set forth in Section 9 hereof, the Commission shall promptly return or cause the return of the Good Faith Deposit to the Representative. Upon such return of the Good Faith Deposit to the Representative, this Purchase Contract shall terminate, and neither party shall have any further obligations hereunder.

Section 11. Expenses.
(a) Commission.

The Bonds are being issued pursuant to the Constitution and the laws of the State of California, the Charter of the City and County of San Francisco (“City”), and a Forty-Third Supplemental Indenture, dated as of July 1, 2023 (the “Forty -Third Supplemental Indenture”) and a Forty -Fourth Supplemental Indenture, dated as of July 1, 2023 (the “Forty- Fourth Supplemental Indenture”), each between the Commission and U.S. Bank Trust Company, National Association, as successor trustee (“Trustee”), supplementing the Amended and Restated Indenture, dated as of August 1, 2002, between the Commission and the Trustee, as successor trustee, as amended and supplemented to date (collectively, the “Indenture”). All capitalized terms not otherwise defined herein shall have the meanings ascribed to such terms in the Indenture.

In connection therewith, the undersigned has examined such documents, certificates and instruments as the undersigned deemed necessary for the purposes of this opinion, including, but not limited to, the Indenture, the Purchase Contract, dated [_______] , 2023 (the “Purchase Contract”), by and between the Commission and Wells Fargo Bank, N.A., as representative of the underwriters named therein, the Continuing Disclosure Certificate of the Commission, as executed and delivered on the date of delivery of the Bonds (“Continuing Disclosure Certificate”), and Resolution No. [_____] of the Commission adopted on [June 27], 2023 (“Commission Resolution”).

In reviewing the documents and matters referred to above, the undersigned has not undertaken to verify independently and has assumed the accuracy of the factual matters represented, warranted or certified therein. The undersigned has examined the Charter of the City.

The opinions expressed herein are based on an analysis of existing laws, regulations, rulings and court decisions and cover certain matters not directly addressed by such authorities. Such opinions

A-2

3760032.6 046549 AGMT
may be affected by actions taken or omitted or events occurring after the date hereof. We have not undertaken to determine, or to inform any person, w hether any such actions are taken or omitted or events do occur or any other matters come to our attention after the date hereof. We disclaim any obligation to update this opinion. We have assumed the genuineness of all documents and signatures presented to us (whether as originals or as copies) and the due and legal execution and delivery thereof by, and validity against, any parties other than the Commission. In addition, we call attention to the fact that the rights and obligations under the Indenture and the Bonds and their enforceability may be subject to bankruptcy, insolvency, reorganization, arrangement, fraudulent conveyance, moratorium and other laws relating to or affecting creditors’ rights, to the application of equitable principles, to the exercise of judicial discretion in appropriate cases and to the limitations on legal remedies against cities and counties in the State of California. We express no opinion with respect to any indemnification, contribution, penalty, choice of law, choice of forum, choice of venue, waiver or severability provisions contained in the foregoing documents.

Based upon and subject to the foregoing, the undersigned is of the opinion that:

1. The Commission is duly organized and validly existing as a commission of the City under and pursuant to the Charter of the City.

2. The Commission Resolution was duly passed at a meeting of the Commission. The meeting was called and held pursuant to law, with all public notice required by law and at which a quorum was present and acting throughout. The Commission Resolution is in full force and effect, as of the date hereof, and has not been modified, amended or rescinded since its approval date.

3. To the best of the undersigned’s knowledge, no action, suit, proceeding, inquiry or investigation, at law or in equity before or by any court, governmental agency, public board or body, is pending or threatened against the Commission to restrain or enjoin the issuance of the Bonds, or in any way contesting the validity of the Indenture, Continuing Disclosure Certificate, the Purchase Contract, or the City Resolution.

4. There is no litigation pending, with service of process having been accomplished, questioning the existence of the City or the Commission, or contesting the power of the Commission to fix water rates and charges, or in any way contesting or affecting (i) the proceedings under which the Bonds are to be issued, (ii) the validity of the Bonds or the validity of the Indenture, (iii) the pledge of Revenues by the Commission under the Indenture or (iv) the title to the office of the present members of the Board of Supervisors or the Commission; nor are there suits or claims against the City or the Commission which would materially impair the ability of the Commission to pay principal or interest on the Bonds when due.

5. The Indenture, Continuing Disclosure Certificate and the Purchase Contract have been duly authorized, executed and delivered by the Commission, and constitute valid and binding agreements of the Commission enforceable in accordance with their respective terms.

6. To the best of the undersigned’s knowledge, except as otherwise disclosed in the Official Statement, neither the execution nor the delivery by the Commission of the Indenture, the Continuing Disclosure Certificate or the Purchase Contract, the adoption of the Commission Resolution, or the compliance by the Commission with such documents or authorizations, conflicts with or constitutes a material breach of, or default under, any applicable law or administrative regulation of the State or the United States, or any other statute or administrative rule or regulation, judgment, decree, order, license, permit, agreement or instrument to which the Commission is subject, which breach, default or conflict would have a material adverse effect on the ability of the
