	unless terminated or extended prior to expiration of term by 
	mutual agreement at an earlier date.

	B. WATER SERVICE PROVISIONS

3.    Quantity of Water
	Contractor shall purchase from Zone 7 all water required by 
	Contractor for use within Contractor's service area as defined in 
	Section 6 except that Contractor may extract groundwater as 
	provided in the Groundwater Extraction Provisions herein or 



                                 31



	obtain water from Other Sources under the conditions in Section 
	5.  No quantity of water purchased from Zone 7 or extracted as 
	part of Contractor's Groundwater Pumping Quota shall be delivered 
	by or provided from Contractor to any area other than 
	Contractor's service area, except for short-term emergency and/or 
	public health purposes.

4.    Quality of Water
	All treated water to be delivered by Zone 7 to Contractor shall 
	be of a quality that complies with the Requirements for Drinking 
	Water of the California Department of Health Services and the 
	United States Environmental Protection Agency or their successor 
	regulatory agencies.  Zone 7 will endeavor to provide treated 
	water that is aesthetically acceptable to the Contractor's 
	customers.  Zone 7 will blend its different sources of water 
	within its operational capabilities to provide water of 
	approximately equal quality to Each Contractor.

5.    Water from Other Sources
	In order to protect Zone 7's financial interest, Contractor shall 
	not contract for, purchase or receive, with or without 
	compensation, either directly or indirectly, any water for use in 
	its service area from any source other than by extraction of its 
	Groundwater Pumping Quota or from purchase from Zone 7, except 
	for any one or more of the following:

	(a)  The water received is for fire flow or fire storage 
	     requirements or other emergency purposes;

	(b)  The water delivered through Zone 7's turnout facility does 
	     not comply with drinking water requirements of California 
	     Department of Health Services, United States Environmental 
	     Protection Agency, or successor regulatory agencies.  The 
	     quantity of water obtained shall be limited to that 
	     necessary to meet Contractor's treated water needs as a 
	     result of Zone 7's non-compliance with said drinking water 
	     requirements;

	(c)  Zone 7 is unable to deliver the quantity of treated water 
	     necessary to satisfy the requirements of Contractor.  Zone 7 
	     shall specify the quantity of treated water that it cannot 
	     deliver and the time period for which it cannot satisfy the 
	     Contractor's requirements.  Contractor is otherwise 
	     obligated to secure all water from Zone 7 to the extent Zone 
	     7 can provide it;

	(d)  Zone 7 is able to meet Contractor's water delivery request, 
	     and Contractor has paid Zone 7 for obligated fixed costs of 
	     Zone 7 associated with the quantity of water the Contractor 
	     will obtain from Other Sources.  These obligated fixed costs 
	     shall include but are not  limited to water facility 
	     improvements, water contract obligations, and debt service 
	     thereto incurred by Zone 7 in supplying water that would 
	     have gone to the Contractor, and for which said costs would 
	     have been recovered through the sale of said water to 


                                 32


	     Contractor.  The Contractor shall obtain the prior written 
	     approval from the Board which approval shall not be 
	     unreasonably withheld;

	(e)  The source of water is groundwater extracted within Zone 7's 
	     boundary but outside the Main Basin provided said extraction 
	     does not cause an adverse impact on the Main Basin; or

	(f)  The source of water is recycled water from Contractor's or 
	     Other Contractors' treated wastewater.

6.    Contractor's Service Area
	As used herein, the Contractor's service area shall include all 
	areas presently served water by Contractor.  Contractor's service 
	area shall also include any future areas to be served by the 
	Contractor within the boundaries of Zone 7 subject to Subsection 
	32c.  Contractor may include any future areas outside the 
	boundaries of Zone 7 upon a finding of the Board that providing 
	water to said area is in the best interests of Zone 7 and after 
	written modification of this contract providing for said service 
	area. The Contractor's present service area is designated on the 
	map attached hereto as Exhibit D.  Contractor shall promptly 
	notify Zone 7 of changes in its service area, as may occur from 
	time to time, by furnishing a map to Zone 7 showing any change in 
	said service area so that Zone 7 can maintain a map indicating 
	the most recent Zone 7 water service area.  Said changes in 
	service area shall be in accordance with the requirements of the 
	Local Agency Formation Commission, Public Utility Commission or 
	other agency having authority to set service areas.

	Any future areas outside Zone 7 boundaries to be served by 
	Contractor which receive water from sources other than Zone 7 or 
	the Main Basin shall not be considered part of the Contractor's 
	service area under the terms of this contract. 



7.   Turnout Facilities

	a.  Turnout facilities shall be constructed at the general 
	    location requested by Contractor.  The exact location shall 
	    be determined by Zone 7 after consultation with Contractor.  
	    Turnout facilities shall be designed and/or constructed 
	    either by Zone 7 or by Contractor (upon the written approval 
	    of Zone 7) based on the ranges of flow set forth in Section 
	    9.  Turnout facilities shall include the necessary valves, 
	    piping, meter and recording equipment, vaults, telemetry 
	    equipment and any other appurtenances necessary to meet the 
	    standards and operational needs of Zone 7.  Zone 7 shall 
	    submit its design of new turnout facilities to contractor 
	    for review and written approval. 

	b.  Contractor shall reimburse Zone 7 for all costs incurred by 
	    Zone 7 related to the new turnout facilities including but 
	    not limited to design, engineering, design review, 


                                 33


	    construction, right-of-way and acquisition thereof, 
	    inspection, and contract administration.  Contractor shall 
	    also pay all costs for the installation of all associated 
	    landscaping and recognizes that Zone 7 shall not be 
	    responsible for maintenance of landscaping under the terms 
	    and conditions of this contract.  Contractor further agrees 
	    to grant or cause to be granted to Zone 7 the necessary 
	    permanent right-of-way and right of ingress thereto and 
	    egress therefrom, as determined by Zone 7, for the purposes 
	    of constructing, operating and maintaining said turnout 
	    facilities.

	c.  Zone 7 shall install the nozzle outlet portion of all 
	    turnout facilities requested by Contractor prior to the 
	    construction of the transmission pipeline.  For turnout 
	    facilities requested by Contractor subsequent to the 
	    construction of Zone 7's transmission pipeline, Contractor 
	    shall pay for the nozzle outlet portion of the turnout 
	    facility, and all costs set forth in subsection b. above.  
	    Ownership of turnout facility, including the shut off valve 
	    downstream of the turnout facility, shall be with Zone 7, 
	    and Contractor shall have no obligation to operate, 
	    maintain, repair, replace or relocate the same.

8.   Measurement of Treated Water Deliveries
	At any time or times, Contractor may, upon request, inspect said 
	turnout facilities (in the presence of a Zone 7 representative), 
	and the measurements and records taken therefrom.  Zone 7 shall 
	test and calibrate the instrumentation at each turnout meter at 
	least annually and furnish such results to the Contractor.  When 
	requested by the Contractor, Zone 7 shall test and calibrate any 
	meter through which treated water is served to Contractor.  The 
	Contractor shall have the right to be represented by a qualified 
	observer at and during any instrumentation and/or meter tests 
	and/or calibration.  Whenever testing and/or calibration of the 
	instrumentation and/or the meter is requested by Contractor, and 
	in the event that any such test shall disclose an error exceeding 
	two percent (2.0%), an adjustment shall be made in charges 
	against the Contractor covering the known or estimated period of 
	duration of such error, but in no event exceeding six (6) months, 
	and the expenses of such test shall be borne by Zone 7; 
	otherwise, such expenses shall be borne by Contractor requesting 
	such tests.

9.   Ranges of Flow
	a.  It is recognized that the range of flow rates of water 
	    through a turnout facility may vary considerably over the 
	    contract term.  A normal range of flow rates for a turnout 
	    facility is hereby established as from ten percent (10%) to 
	    one hundred percent (100%) of a maximum design flow rate.  
	    Contractor shall provide Zone 7 with the following 
	    information for each turnout facility prior to the design of 
	    such facilities:
	      (1)     Anticipated ultimate (future) maximum flow rate,
	      (2)     Anticipated present design range of flow rates.  (The 


                                 34


		      maximum design flow rate shall not exceed ten (10) times
		      the minimum design flow rate for this range in normal 
		      installations.)
		(3)   Anticipated pressure ranges for (1) and (2) above on the
		      Contractor's side of the turnout facility.

	b.  Zone 7 shall design the metering and/or recording 
	    installation for the range set forth in accordance with 
	    Subsections (2) and (3) above with provisions for future 
	    modifications in accordance with a range based on 
	    Subsections (1) and (3) above.

	c.  Contractor shall regulate the flow demands through the 
	    turnout facility such that the range of flow rates set forth 
	    in accordance with Subsection b above will be maintained 
	    insofar as such regulation is reasonable and practicable.  
	    Zone 7 shall make modification of the metering and/or 
	    recording equipment upon request of Contractor or at such 
	    time that the actual flow rate exceeds the maximum design 
	    flow rate or is less than the minimum design flow rate; 
	    provided, however, that flow rates resulting from 
	    emergencies shall not apply to such requirement for 
	    modification.  Said modification will be at the expense of 
	    the Contractor and payment thereof shall be in accordance 
	    with Section 27.

10.  Delivery Schedule of Municipal & Industrial Water
	Each year, the Contractor shall submit in writing to Zone 7 a 
	preliminary water delivery schedule on a form provided by Zone 7 
	indicating the anticipated quantity of treated water and 
	groundwater in excess of its Groundwater Pumping Quota required 
	by Contractor during each month of the succeeding five (5) 
	calendar years and the anticipated peak day treated water demand 
	from Zone 7 for each such year.  Zone 7 shall review such 
	schedule, and after consultation with Contractor, shall approve 
	such schedule in a timely manner or make such revisions in the 
	same as may, in the judgment of Zone 7, be necessary to make such 
	deliveries.  To the extent water is available to Zone 7, Zone 7 
	will approve in writing, a delivery schedule each year for 
	delivery to Contractor during the next succeeding calendar year 
	of an amount of water not less than the amount of water set forth 
	in the approved schedule for the then-current calendar year.  The 
	amount of water set forth in the approved delivery schedule for 
	the next succeeding calendar year shall be the basis for which 
	Zone 7 shall contract with the State of California or other 
	entity for delivery to Zone 7.  Zone 7 shall identify the reason 
	for any revisions or disapproval of Contractor's delivery 
	request.  Zone 7 shall only revise or disapprove Contractor's 
	delivery request for the reasons set forth in Sections 12, 13, 14 
	or 15.

11.  Reporting Use of Water
	The Contractor shall report to Zone 7 on or before the tenth day 
	of each month the total volume, in acre-feet, of groundwater 
	extracted from the Main Basin and any water obtained from Other 
	Sources (including any water recharged to the Main Basin) for the 
	preceding month.  The report shall become the basis for which 

                                 35

	water charge determinations and hydrologic inventory calculations 
	of the Main Basin are made by Zone 7.  Said report shall be made 
	on a form or forms provided by or acceptable to Zone 7.  The 
	measurement and recordation of such flows shall be subject to the 
	same provisions for inspection and testing of meters and 
	instrumentation by Zone 7 as is provided to Contractor in 
	Section 8.  

12.  Peak Demands
	The Zone 7 system is not designed to serve all Contractor's peak 
	demands.  As water demands increase, it may be necessary to 
	curtail peak deliveries to conform to Zone 7 system capacity as 
	it exists from time to time.  However, so long as water and line 
	capacity are available, Zone 7 will endeavor to meet all 
	reasonable demands for peak deliveries and will use reasonable 
	diligence to provide a regular and uninterrupted supply of water 
	from its turnout facility, but shall not be liable to Contractor 
	for damages, breach of contract, or otherwise, for failure, 
	suspension, diminution, or other variations of service occasioned 
	by any cause beyond the control of, or without the fault or 
	negligence of Zone 7.  Such causes may include, but are not 
	restricted to, acts of God, acts of war, or criminal acts of 
	others, acts of Contractor or Other Contractors, water shortages, 
	fires, floods, earthquakes, epidemics, quarantine restrictions, 
	strikes, or failure or breakdown of transmission or other 
	facilities.

13.  Curtailment of Delivery During Maintenance Periods
	Zone 7 will make all reasonable effort to provide continuous 
	service to Contractor but may schedule to temporarily discontinue 
	or reduce the delivery of water to Contractor for the purpose of 
	necessary investigation, inspection, maintenance, repair or 
	replacement of any of the facilities necessary for the delivery 
	of treated water to Contractor.  Zone 7 shall notify Contractor 
	as far in advance as possible of any scheduled discontinuance or 
	reduction and the estimated duration of such discontinuance or 
	reduction.  Recognizing that Contractor may rely on Zone 7 for 
	deliveries of water with minimal interruption, particularly 
	during the high water consumption months, Zone 7 shall use its 
	best efforts to make any such discontinuance or reduction in the 
	delivery of water only during the period of November through 
	March.  In the event of any discontinuance or reduction in 
	delivery of water, Contractor may elect to receive the amount of 
	water that otherwise would have been delivered to it during such 
	period under the approved water delivery schedule at other times 
	during the year, consistent with Zone 7's delivery ability 
	considering the then current delivery schedules of all Other 
	Contractors.

14.  Availability of Water
	In any year in which a shortage occurs due to drought or other 
	cause in the supply of water available for delivery to Each 
	Contractor such that the supply to Zone 7 is less than the total 
	amount included in the approved delivery schedule of Each 
	Contractor for that year, Zone 7 shall reduce deliveries to Each 


                                 36


	Contractor in an amount that results in a reduction of total 
	water used within Contractor's service area that is equal to the 
	percent reduction for total water used within Zone 7's service 
	area for that year, all as determined by Zone 7; provided, that 
	Zone 7 may apportion on another basis if such is required to meet 
	minimum demands for domestic supply, fire protection, or public 
	health during the year.

	The amount of water available under this contract and Zone 7's 
	obligation to supply water shall be subject to the terms and 
	conditions of the contract between Zone 7 and the State of 
	California for water service via the South Bay Aqueduct and any 
	other contracts Zone 7 may enter into for water supply; provided, 
	further, that wherever the provisions of the contract with the 
	State of California or other entity as to the availability of 
	water conflict with the provisions of this contract, the terms 
	and provisions of this contract shall prevail.  Zone 7 shall give 
	Contractor written notice as far in advance as possible of any 
	reduction in deliveries that would be necessary because of a 
	shortage in water supply.  Neither Zone 7 nor any of its 
	officers, agents, or employees shall be liable for any damage, 
	direct or indirect, arising from this contract caused by drought, 
	regulatory constraints, operation of area of origin statutes, or 
	any other cause beyond the control or without the negligence of 
	Zone 7.

15.  Suspension of Service
	In the event that Contractor shall be delinquent in the payment 
	for water for more than ninety (90) days after the due date (as 
	said due date is defined in Section 28), such delinquency shall 
	be called to the attention of the Board and the Board may, in its 
	discretion and after giving Contractor an opportunity to be 
	heard, order the suspension or reduction of service to 
	Contractor.

	C.  GROUNDWATER EXTRACTION PROVISIONS

16.  Groundwater Pumping from the Main Basin
	Zone 7 acknowledges Contractor's right to extract groundwater 
	based on Contractor's historical groundwater extractions and 
	based on the mutually agreed upon limitations in Contractor's 
	original water supply contract with Zone 7.  Contractor 
	acknowledges that Zone 7 manages the Main Basin and that Zone 7 
	recharges, stores, and extracts from the Main Basin as necessary 
	to supply water to Each Contractor.  Accordingly, Contractor 
	shall not extract under this agreement, more than   3,069 acre-
	feet (1,000 million gallons), its Groundwater Pumping Quota, from 
	the Main Basin in any calendar year except as follows:

	(a)  The Contractor pays Zone 7 a recharge fee for recharging the 
	     Main Basin as set forth in Section 17;

	(b)  The groundwater extracted is Contractor's accumulated carry-
	     over of its Groundwater Pumping Quota from prior years as 
	     provided in Section 18; or

                                 37



	(c)  The source of the groundwater extracted is from Other 
	     Sources obtained by Contractor pursuant to 5(c), 5(d), and 
	     5(f) herein and the Contractor has previously recharged said 
	     groundwater into the Main Basin.  Said recharged water shall 
	     not adversely impact Zone 7's use of the Main Basin, 
	     including the recharge, storage or extraction thereof. 

17. Recharge Water
	In any calendar year, if Contractor should extract groundwater 
	from the Main Basin in an amount in excess of its Groundwater 
	Pumping Quota plus any accumulated carry-over and any groundwater 
	recharged by Contractor per 16 (c),  Contractor shall pay Zone 7, 
	in addition to other payments required by this contract, a 
	recharge fee as set forth in the rate schedule and Sections 23 
	and 24 herein, for each acre-foot of water (or portion thereof) 
	in excess of said amount.  In express consideration of 
	Contractor's agreement to pay such  recharge fee, as aforesaid, 
	Zone 7 shall recharge the Main Basin in an amount aggregating the 
	quantity of such excess water.

	Because said recharge fee would be in the nature of an assessment 
	fee upon annual extractions in excess of the Groundwater Pumping 
	Quota, if Zone 7 (or any other public body or agency) shall 
	impose a valid replenishment assessment fee or other charge upon 
	or measured by the pumping or extraction of water for use in 
	Contractor's service area, then the provisions of this Section 
	shall be superseded accordingly, except as to any payment 
	attributable to a period prior to the effective date of any such 
	assessment fee or other charge.

18.  Carry-over of Groundwater Pumping Quota
	If, in any calendar year, Contractor does not extract its entire 
	Groundwater Pumping Quota from the Main Basin, Contractor may 
	carry-over from that calendar year the unextracted portion of 
	Groundwater Pumping Quota for extraction from the Main Basin 
	during subsequent calendar years.  Said carry-over or accumulated 
	carry-over shall not exceed 20 percent of the Contractor's 
	Groundwater Pumping Quota.  Said carry-over shall not include any 
	Groundwater Pumping Quota waived under the In-Lieu Treated Water 
	provision of Section 19.

19.  In-Lieu Treated Water
	During periods when sufficient water is available to Zone 7 at 
	reasonable cost and Zone 7 desires to raise or maintain 
	groundwater levels, Zone 7 will offer delivery of treated water 
	at a cost that is less than treated water rates to Contractor in 
	lieu of Contractor extracting groundwater per its Groundwater 
	Pumping Quota.  The amount of In-Lieu Treated Water that 
	Contractor may receive shall not exceed its Groundwater Pumping 
	Quota plus any accumulated carry-over or its operational 
	capability to extract said Groundwater Pumping Quota and 
	accumulated carry-over.  Zone 7's offer to deliver In-Lieu 
	Treated Water for a given calendar year will be made on or about 
	May 1 of that year, however, said rates may be retroactive for 


                                 38



	the entire calendar year or other mutually agreed upon portion 
	thereof.  Credit or payment for In-Lieu Treated Water will be as 
	provided for under Section 25.  Contractor is not required to 
	take or purchase any In-Lieu Treated Water.

	Contractor acknowledges that any credits or payments received 
	under Section 25 are received in-lieu of the Contractor's right 
	to extract its Groundwater Pumping Quota, and Contractor agrees 
	that its Groundwater Pumping Quota and any accumulated carry-over 
	shall be reduced by an amount equivalent to the amount of In-Lieu 
	Treated Water delivered by Zone 7 to Contractor for the year in 
	which the delivery is made.

20.  Water Delivery Shortage Emergency Extractions
	During a water supply emergency, as declared by the Board, in 
	which Zone 7 is unable to deliver the quantity of treated water 
	as approved on the delivery schedule, the Contractor may extract 
	water from the Main Basin in excess of the Contractor's 
	Groundwater Pumping Quota at a reduced recharge rate.  Said rate 
	shall be the same as the In-Lieu Treated Water rate.

21.  Transfer of Groundwater Pumping Quota
	Temporary or permanent transfer of Contractor's Groundwater 
	Pumping Quota outside of the Zone 7 boundary shall not be 
	permitted.  Temporary or permanent transfer of Contractor's 
	Groundwater Pumping Quota within Zone 7's boundary shall be 
	permitted provided that it is transferred to an Other Contractor.  
	Said transfer of Contractor's Groundwater Pumping Quota shall be 
	permitted upon written notification to Zone 7 from each 
	contractor that is a party to the transfer. 
 
22.  Changes in Contractor's Groundwater Pumping Quota
	The annual Safe Yield of the Main Basin, estimated as 
	approximately 13,200 acre-feet per year in 1993, is essentially 
	the same as the long-term average extraction by existing 
	groundwater producers.   The Board shall not increase any Other 
	Contractor's Groundwater Pumping Quota unless such increase in 
	Groundwater Pumping Quota is acceptable to Each Contractor with a 
	Groundwater Pumping Quota.

	Neither Contractor nor Zone 7 waives any rights to pursue a court 
	adjudication of the safe yield of the Main Basin or any other 
	court action on extraction of groundwater from the Main Basin 
	that may change Contractor's Groundwater Pumping Quota.  
	Furthermore, Zone 7 reserves its authority to levy a 
	replenishment assessment on the extraction of any groundwater, 
	including Contractor's Groundwater Pumping Quota (excluding any 
	adjudication of the safe yield), as necessary to protect the 
	water supplies for users within Zone 7.

	D.  CHARGE AND PAYMENT PROVISIONS

23.  Rate Schedule
	Zone 7 shall charge for water in accordance with a rate schedule 


                                 39



	for water service, as such rate schedule is established or 
	amended by the Board.  The Board shall review the rate schedule 
	and establish a rate schedule for each calendar year period in 
	accordance with the most recent costs and revenues of Zone 7.  
	The Board shall review the rate schedule at the September regular 
	meeting and endeavor to establish the rate schedule at the 
	November regular meeting prior to January 1 of the following 
	calendar year for which the rate schedule is to be effective.  
	The rates, including but not limited to the treated water, 
	in-lieu treated water, meter fee, and recharge fee, to be so 
	established, shall be based on the cost of providing service, and 
	shall not be unreasonable, arbitrary, or discriminatory.  In the 
	event the Board fails, in conformity to the preceding schedule, 
	to establish a new rate schedule for any calendar year the rate 
	schedule in effect for the prior calendar year shall be continued 
	in full force and effect until otherwise modified by the Board.  

24.  Recharge Fee
	The recharge fee shall be charged to Contractor in accordance 
	with the rates included in the rate schedule.  Contractor shall 
	be invoiced by Zone 7 in accordance with Section 26 at the time 
	in which Contractor exceeds its Groundwater Pumping Quota as 
	provided in Section 17.  Section 28 herein shall apply to said 
	charges.  The recharge fee shall be based upon Zone 7's costs 
	including but not limited to the cost to purchase or develop the 
	water, as well as the cost to construct, maintain, and operate 
	the facilities needed to import, distribute, store, treat and 
	recharge said water into the Main Basin for the benefit of Each 
	Contractor.

25.  In-Lieu Treated Water Credit
	In any calendar year in which the Contractor has foregone pumping 
	of its Groundwater Pumping Quota, plus accumulated carry-over, as 
	set forth in Section 19, Zone 7 shall determine the amount of 
	delivered treated water that should be charged at the In-Lieu 
	Treated Water rate, and shall credit or make payment to the 
	Contractor the difference between the treated water rate and the 
	In-Lieu Treated Water rate.

26.  Time for Payment
	Contractor shall be invoiced on a calendar month basis for 
	charges.  Contractor shall pay promptly all charges invoiced by 
	Zone 7, such invoices to be rendered on or about the 5th day of 
	each month for charges incurred in the preceding month and to 
	become due and payable within 30 days from date of invoice.  In 
	the event that Contractor in good faith contests the accuracy of 
	any invoices submitted to it pursuant to this Section, it shall 
	give Zone 7 notice thereof at least ten (10) days prior to the 
	day upon which payment of the stated amount is due.  To the 
	extent that Zone 7 finds Contractor's contentions regarding the 
	statement to be correct, it shall revise the statement 
	accordingly and Contractor shall make payment of the revised 
	amounts on or before the due date.  To the extent that Zone 7 
	does not find Contractor's contentions to be correct or where 
	time is not available for a review of such contentions prior to 

                                 40



	the due date, Contractor shall make payment of the invoiced 
	amount on or before the due date and make the contested part of 
	such payment under protest and seek to recover the amount thereof 
	from Zone 7.



27.  Payment for Turnout Facilities  
	Prior to commencing with the design of a turnout facility, 
	Contractor shall deposit with Zone 7 an amount of money estimated 
	by Zone 7 to cover all costs to be incurred by Zone 7 for 
	designing said turnout facility or shall request in writing to be 
	invoiced for such design in accordance with Section 26.  The 
	option of invoicing Contractor shall be at the sole discretion of 
	Zone 7.  Prior to constructing said turnout facility, Contractor 
	shall deposit with Zone 7 an amount of money estimated by Zone 7 
	to cover all costs to be incurred by Zone 7 for completion of 
	turnout facility or request to be invoiced for such construction 
	in accordance with Section 26.  Following completion of the 
	construction of the turnout facility, Zone 7 shall submit to 
	Contractor a statement for the actual costs incurred for 
	completion of the design and construction of said turnout 
	facility as provided in Section 7.  The deposit shall be applied 
	to the actual costs incurred by Zone 7, and the appropriate 
	refund or invoicing to Contractor will be made.  Contractor shall 
	make payment of any such invoicing to Zone 7 within thirty (30) 
	days of submission of said statement.  Zone 7 shall refund any 
	deposit in excess of actual cost within thirty days of Zone 7's 
	determination of said cost.  Contractor shall have the right to 
	audit the records of Zone 7 for the purpose of verifying actual 
	costs. 

28.  Delinquent Payments
	In the event that Contractor is delinquent in the payment of 
	invoiced charges for more than thirty (30) days after the due 
	date, delinquent amounts shall accrue at the legal rate of 
	interest commencing on the due date and continuing each month 
	thereafter until payment of both the principal amount of such 
	charges and the interest thereon is paid in full insofar as 
	permitted by law.  Unless otherwise determined by law, the legal 
	rate of interest shall be the combined per annum discount rate of 
	the Federal Reserve Bank of San Francisco on the 25th day of the 
	current month and five percent (5%).

	E.  GENERAL PROVISIONS

29.  Remedies
	By reason of the specialized nature of the water service 
	rendered, and for the further reason that the extent of any 
	damage caused to either party by the other by reason of any 
	breach of this contract or agreement may be extremely difficult 
	to determine, it is agreed by the parties hereto that an action 
	for damages is an inadequate remedy for any breach, and that 
	specific performance, without precluding any other remedy 


                                  41



	available in equity or law, will be necessary to furnish either 
	party hereto with an adequate remedy for the breach thereof.
 
30.  Assignment
	This contract is not for the benefit of any person, corporation 
	or other entity, other than the parties hereto, and no person, 
	corporation or other entity except the parties hereto, shall have 
	any rights or interest in or under this contract unless otherwise 
	specifically provided herein. Contractor shall not assign or 
	transfer any rights or privileges under this contract, either in 
	whole or in part, without the prior written consent of Zone 7, 
	which consent shall not be unreasonably withheld, or make any 
	transfer of all or any part of its water system, or allow the use 
	thereof, in any manner whereby any provisions of this contract 
	will not continue to be binding on it, its assignee or 
	transferee, or such user of the system.  This contract and the 
	rights and responsibilities provided for herein shall be binding 
	on the successors and assigns of the parties hereto.
 
31.  Contract Modification
	This contract may be amended or modified any time only by mutual 
	written agreement of the parties.

32.  Liabilities
	a.   Zone 7 and/or any of its officers, agents or employees shall 
	     not be liable for the control, carriage, handling, use, 
	     disposal, or distribution of treated water supplied to 
	     Contractor by Zone 7, after such water has passed through 
	     the turnout facility or for claims of damage of any nature 
	     whatsoever, including but not limited to property damage, 
	     personal injury or death, arising out of or connected with 
	     the control, carriage, handling, use, disposal or 
	     distribution of such water beyond said turnout facility.   
	     Contractor shall indemnify, save and hold harmless Zone 7 
	     and its officers, agents, and employees from any such 
	     damages or claims of damages.  Contractor shall further 
	     reimburse Zone 7 for costs of repair of Zone 7's facilities 
	     and other damages resulting from the operations of 
	     Contractor.  

	b.   Contractor and/or any of its officers, agents, or employees 
	     shall not be liable for the control, carriage, handling, 
	     use,  disposal, or distribution of water prior to such water 
	     being delivered through the turnout facility or for claims 
	     of damage of any nature whatsoever, including but not 
	     limited to property damage, personal injury or death, 
	     arising out of or connected with the control, carriage, 
	     handling, use, disposal, or distribution of such water prior 
	     to its delivery to Contractor, excepting, however, claims by 
	     Zone 7 for costs of repair to Zone 7's facilities and other 
	     damages resulting from the operations of the Contractor.  
	     Zone 7 shall indemnify, save and hold harmless the 
	     Contractor and its officers, agents, and employees from any 
	     such damages or claims of damages, except claims by Zone 7 



                                 42


	     for costs of repair of Zone 7's facilities and other damages 
	     resulting from the operations of Contractor.  

	c.   Zone 7 needs to be protected from any obligation to supply 
	     water to projects or consumers which the contractor has 
	     supplied from sources other than what has been directly 
	     purchased from Zone 7.  Accordingly, any other provision 
	     herein notwithstanding, Zone 7 shall not be obligated nor 
	     liable to provide, without exception, that quantity of water 
	     obtained by Contractor pursuant to Subsections 5a-f, to 
	     Contractor or any customer of Contractor regardless of 
	     purpose.  Accordingly, Contractor shall indemnify, save and 
	     hold harmless Zone 7 from any and all obligations, 
	     liability, responsibility, costs, expenses, or fees 
	     associated in any way with any claims, demands, requests, 
	     suits, causes of action of whatever type or nature 
	     concerning the provision of any quantity of water obtained 
	     by Contractor pursuant to Subsections 5a-f herein.
 
	d.   Likewise, if pursuant to Section 3 herein, Contractor is 
	     instructed by Zone 7 to acquire water from Zone 7 which has 
	     been previously acquired from third parties pursuant to 
	     Subsections 5a-f herein, Zone 7 shall save and hold harmless 
	     Contractor from any and all obligations, liability, 
	     responsibility, costs, expenses, or fees that may arise from 
	     such third parties.
		
33.   Renewability
	At the expiration of the thirty (30) year term of this contract, 
	said contract may be renewed upon the mutual consent of the 
	parties hereto.  If no such renewal shall take place and in the 
	absence of any new contract, Zone 7 shall nevertheless continue 
	delivery to Contractor in accordance with this contract, that 
	quantity of water set forth in the approved delivery schedule for 
	the last full calendar year before the expiration of the term of 
	this contract.  However, if a new contract is not entered into 
	within two (2) years from the date of expiration of this 
	contract, then the Board may, at its option, set the terms and 
	conditions for a Municipal & Industrial Water Supply.

34.   Notices
	All notices or other writings in this contract provided to be 
	given or made or sent, or which may be given or made or sent, by 
	one party hereto to another, shall be deemed to have been fully 
	given or made or sent when made in writing and deposited in the 
	United States mail, registered, certified or first class, postage 
	prepaid, and addressed as follows:

	The address to which any notice or other writing may be given or 
	made or sent to any party may be changed upon written notice 
	given by such party as provided above.

35.  Severability
	If any one or more of the terms or conditions set forth in this 
	contract to be performed on the part of Zone 7 or Contractor, or 
	either of them, should be contrary to any provisions of law or 
	contrary to the policy of law to such an extent as to be 
	unenforceable in any court of competent jurisdiction, then such 
	terms or conditions, shall be null and void and shall be deemed 
	severable from the remaining terms or conditions and shall not 
	affect the validity of the remaining provisions of this contract.



36.  Section Headings
	Section headings in this contract are for convenience only and 
are not to be construed as a part of this contract or in any way 
limiting or amplifying the provisions hereof.

37.  Waiver
	None of these terms or conditions herein contained can be waived 
except by mutual written consent.

38.  Water Conservation
	In order to increase water supply by demand reduction or to 
comply with regulatory requirements, Zone 7 will undertake and 
support water conservation programs.  To that end, Zone 7 will 
develop, implement or participate in such programs and enter into 
agreements with Other Contractors, and other entities to make 
more efficient use of water supplies through water conservation 
programs so long as such agreements serve a beneficial purpose to 
the residents of Zone 7.

39.  Contracts to be Substantially Similar
	Zone 7 agrees that each contract for a Municipal & Industrial 
Water Supply hereafter entered into by Zone 7 with any Other 
Contractor shall contain provisions substantially similar to 
those herein set forth and shall not contain any provisions of a 
material nature more favorable to the Other Contractor than the 
provisions herein applicable to Contractor.  This section shall 
not restrict Zone 7 from considering other terms and conditions 
for subsequent Municipal & Industrial Water Supply contracts 
provided that if such other terms and conditions are not 
substantially similar, Zone 7 shall notify all Other Contractors 
and offer such other terms and conditions in accordance with 
Section 31 to Each Contractor.  This section shall not limit Zone 
7 from entering into other contracts for services not provided 

                                 44




for under the terms and conditions of this contract.

IN WITNESS WHEREOF, the parties hereto and have executed this 
contract on the date and year first above written.
