CERTAIN TERMS AND ISSUANCE OF THE BONDS

SECTION 2.01. Designation of Bonds.

The changes, modifications and supplements to the Base Indenture effected by this Supplemental Indenture shall be applicable only with respect to, and govern the terms of, the Series CC Bonds and shall not apply to any other Bonds that have been or may be issued under the Base Indenture unless a supplemental indenture with respect to such other Bonds specifically incorporates such changes, modifications and supplements. Pursuant to this Supplemental Indenture, there is hereby designated a series of Bonds under the Base Indenture entitled “9.86% First Mortgage Bonds due 2020, Series CC.”

SECTION 2.02. Aggregate Principal Amount.

The aggregate principal amount of the Series CC Bonds which may be outstanding under the terms of this Supplemental Indenture after the date hereof is $17,800,000, except for Series CC Bonds authenticated and delivered in accordance with Sections 2.15, 2.16, 2.18, 4.07 and 12.06 of the Base Indenture.

SECTION 2.03. Form; Payment of Interest and Principal on Bonds.

(a) General. Without limiting the foregoing provisions of this Article II, the Series CC Bonds shall be issued as Definitive Bonds substantially in the form set forth in EXHIBIT A hereto. The Series CC Bonds will be issued in denominations of $1,000 and integral multiples thereof. To the extent that any provision of the Definitive Bonds representing the Series CC Bonds conflicts with the express provisions of this Supplemental Indenture or the Base Indenture, this Supplemental Indenture or the Base Indenture shall govern and be controlling.

(b) Payment of Interest and Principal on Bonds. The Series CC Bonds will mature on November 1, 2020 and will bear interest at the rate of 9.86% per annum. Interest on the Series CC Bonds will be payable semi-annually in arrears on May 1 and November 1 of each year to the Holders thereof at the close of business on the immediately preceding April 15 and October 15 of each year. Interest on the Series CC Bonds will accrue from the most recent date to which interest has been paid. Interest shall be computed on the basis of a 360-day year comprised of twelve 30-day months.

(c) Default Interest. During the occurrence and continuation of an Event of Default, all amounts owing under the Series CC Bonds shall, to the extent permitted by applicable law, bear additional interest at a per annum rate equal to 2%.

(d) Method and Place of Payment. The Company shall cause payments of all amounts payable to the Holder in respect of the principal of, or premium, if any, or interest on, any of the Bonds to be made by bank wire transfer of immediately available funds. Except in the event of the payment or redemption of the Bonds as a whole, the Company shall cause such payments to be made to the Holders without the surrendering or presentation to the Trustee of any Series CC Bond. The Holders agrees to make notations on such Series CC Bond of payment of the portion thereof so paid and that, before selling, transferring or otherwise disposing of any of the Series CC Bonds, the Holder shall surrender the same to the Trustee in exchange for a Series CC Bond in authorized denominations, aggregating the same principal amount as the unpaid principal amount of the Series CC Bonds surrendered.

SECTION 2.04. Taxes.

Unless required by the laws of the United States of America or the State of California, the Series CC Bonds shall not require the deduction or withholding by the Company of any taxes or any reimbursement of taxes to the Holders of the Series CC Bonds.

SECTION 2.05. Parent Guarantee.

The obligations of the Company under the Series CC Bonds shall be guaranteed by Parent, the form of which guarantee is set forth in EXHIBIT B hereto.

SECTION 2.06. Transfer Expenses.

Notwithstanding anything to the contrary in the Base Indenture, (i) the Company shall bear all expenses in connection with the preparation, issue, delivery and transfers of the Series CC Bonds, (ii) if the Holder is an insurance company, its own agreement of indemnity shall be deemed to be satisfactory indemnity and security when required or requested by the Company and (iii) in the case of lost, stolen, destroyed or mutilated Series CC Bonds,

the Company at its expense (including payment by it of any governmental charges and other expenses, including those of the Trustee) shall execute and deliver new Series CC Bonds of like tenor and principal amount, dated and bearing interest from the date to which interest has been paid on such lost, stolen, destroyed or mutilated Series CC Bond.

ARTICLE III
OPTIONAL REDEMPTION

The Series CC Bonds are redeemable (1) at the option of the Company, in whole or in part at any time and (2) in connection with an acceleration upon the occurrence of an Event of Default pursuant to Section 7.01 of the Base Indenture at a redemption price (the “Redemption Price”) equal to the sum of:

	•		100% of the principal amount of the Series CC Bonds to be redeemed; plus

	•		the Make-Whole Amount,

plus accrued and unpaid interest to the Redemption Date on the Series CC Bonds to be redeemed.

“Called Principal” means, with respect to any Series CC Bond, the principal of such Series CC Bond that is to be prepaid pursuant to Article III of this Supplemental Indenture or has become or is declared to be immediately due and payable under Section 7.01 of the Base Indenture, as the context requires.

“Discounted Value” means, with respect to the Called Principal of any Series CC Bond, the amount obtained by discounting all Remaining Scheduled Payments with respect to such Called Principal from their respective scheduled due dates to the Settlement Date with respect to such Called Principal, in accordance with accepted financial practice and at a discount factor (applied on the same periodic basis as that on which interest on the Series CC Bonds is payable) equal to the Reinvestment Yield with respect to such Called Principal.

“Make-Whole Amount” means, with respect to any Series CC Bond, an amount equal to the excess, if any, of the Discounted Value of the Remaining Scheduled Payments with respect to the Called Principal of such Series CC Bond over the amount of such Called Principal, provided that the Make-Whole Amount may in no event be less than zero.

“Reinvestment Yield” means, with respect to the Called Principal of any Series CC Bond, .50% over the yield to maturity implied by (i) the yields reported as of 10:00 a.m. (New York City time) on the second Business Day preceding the Settlement Date with respect to such Called Principal, on the display designated as “Page PX1” (or such other display as may replace Page PX1) on Bloomberg Financial Markets for the most recently issued actively traded on the run U.S. Treasury securities having a maturity equal to the Remaining Average Life of such Called Principal as of such Settlement Date, or (ii) if such yields are not reported as of such time or the yields reported as of such time are not ascertainable (including by way of interpolation), the Treasury Constant Maturity Series Yields reported, for the latest day for which such yields have been so reported as of the second Business Day preceding the Settlement Date with respect to such Called Principal, in Federal Reserve Statistical Release H.15 (or any comparable successor publication) for U.S. Treasury securities having a constant maturity equal to the Remaining Average Life of such Called Principal as of such Settlement Date.

In the case of each determination under clause (i) or clause (ii), as the case may be, of the preceding paragraph, such implied yield will be determined, if necessary, by (a) converting U.S. Treasury bill quotations to bond equivalent yields in accordance with accepted financial practice and (b) interpolating linearly between (1) the applicable U.S. Treasury security with the maturity closest to and greater than such Remaining Average Life and (2) the applicable U.S. Treasury security with the maturity closest to and less than such Remaining Average Life. The Reinvestment Yield shall be rounded to the number of decimal places as appears in the interest rate of the applicable Series CC Bond.

by multiplying (a) the principal component of each Remaining Scheduled Payment with respect to such Called Principal by (b) the number of years (calculated to the nearest one-twelfth year) that will elapse between the Settlement Date with respect to such Called Principal and the scheduled due date of such Remaining Scheduled Payment.

“Remaining Scheduled Payments” means, with respect to the Called Principal of any Series CC Bond, all payments of such Called Principal and interest thereon that would be due after the Settlement Date with respect to such Called Principal if no payment of such Called Principal were made prior to its scheduled due date, provided that if such Settlement Date is not a date on which interest payments are due to be made under the terms of the Series CC Bonds, then the amount of the next succeeding scheduled interest payment will be reduced by the amount of interest accrued to such Settlement Date and required to be paid on such Settlement Date pursuant to Article III of this Supplemental Indenture or under Section 7.01 of the Base Indenture, as the context requires.

“Settlement Date” means, with respect to the Called Principal of any Series CC Bond, the date on which such Called Principal is to be prepaid pursuant to Article III of this Supplemental Indenture or has become or is declared to be immediately due and payable under Section 7.01 of the Base Indenture, as the context requires.

Series CC Bonds may be redeemed (i) out of cash held in the sinking fund provided for in Article IV of this Supplemental Indenture or (ii) through the application of the proceeds of the sale of any complete water system or any substantial part of a water system owned by the Company, including without limiting the generality of the foregoing a sale to a municipality or other public body or agency having the power of eminent domain or the right to purchase or order the sale of such property, and, in case of redemption upon any such event, the applicable Redemption Price shall be the principal amount of such Series CC Bonds so redeemed, together with interest accrued thereon to the Redemption Date.

Other than as specifically provided in this Article III, any redemption of Series CC Bonds shall be conducted in accordance with the provisions of Article IV of the Base Indenture.

ARTICLE IV
SINKING FUND

SECTION 4.01. Amount and Time of Payment.

The Company covenants and agrees that it will establish and maintain by annual cash deposits with the Trustee a sinking fund for the benefit of Holders of the Series CC Bonds and for the purpose of retiring and further securing such bonds, all as hereinafter in this Article IV provided. The amount to be deposited annually on or before October 31 of each year in such sinking fund, through the year ending October 31, 2019, shall be $100,000 (the “mandatory sinking fund payment”).

The Company shall have the option to make an additional sinking fund payment (the “optional sinking fund payment”) on the date any mandatory sinking fund payment shall be due, in an amount up to but not greater than the mandatory sinking fund payment due on such date, regardless of whether such optional sinking fund payment shall have been made in any previous year; provided, however, that the option to make such optional sinking fund payments shall not be cumulative. Such optional sinking fund payments shall not affect in any manner the Company’s obligations to make annual sinking fund deposits in accordance with the first paragraph of this Section 4.01.

SECTION 4.02. Application of Sinking Funds Cash to Redemption of Series CC Bonds.

All cash deposited with the Trustee for the sinking fund for Series CC Bonds shall be held in a fund known as “Series CC Sinking Fund Cash”. Notwithstanding any provisions to the contrary in Article IV of the Base Indenture, unless otherwise required by Section 4.03, the Trustee in each year, after the deposit with the Trustee of the sinking fund payment for such year (regardless of whether such payment is a mandatory or an optional sinking fund payment), shall redeem Series CC Bonds from the Series CC Sinking Fund Cash in accordance with the provisions of Article IV of the Base Indenture as if acting upon Company Request. The date for the redemption of

such Series CC Bonds shall be fixed to be the November 1 that is first following the deposit with the Trustee of any such sinking fund payment. However, the Trustee shall redeem Series CC Bonds only in denominations of $1,000 or multiples thereof. If any Holder’s share of the sinking fund payment is not an even multiple of $1,000, the Trustee shall hold for the account of such Holder the difference between the amount of such Holder’s share and the highest multiple of $1,000 which is less than such amount. The Trustee shall apply such sum on the next possible sinking fund redemption date to redeem Series CC Bonds from such Holder in authorized multiples of $1,000.

SECTION 4.03. Limitations on Use of Sinking Fund Cash in Case of Event of Default.

Notwithstanding anything hereinbefore provided, the Trustee shall not use the Series CC Sinking Fund Cash to redeem any Series CC Bonds if it has actual knowledge that an Event of Default has occurred and is continuing with respect to the Series CC Bonds and the Series CC Sinking Fund Cash shall form a part of the trust estate for the equal protection of all Series CC Bonds as above provided for any part of the trust estate.

ARTICLE V
ADDITIONAL PROVISIONS APPLICABLE TO SERIES CC BONDS

SECTION 5.01. Limitations on Issuance of Bonds Against Expenditures for Maintenance and Replacements.

No Bonds shall be issued under the Base Indenture for the purpose of providing funds for the Company to keep or maintain the property pledged pursuant to the Base Indenture in good and business-like working order and condition, or merely to replace or in substitution for old or worn-out or abandoned property; provided, however, that whenever old or worn-out or abandoned property is replaced by Substituted Property costing more than the original cost of the old or worn-out or abandoned property then such replacement or substitution shall be permitted and the excess of cost of such Substituted Property, and such excess only, shall be deemed Permanent Improvements, Extensions or Additions, for which Bonds may be authenticated and delivered under Section 2.02 of the Base Indenture.

SECTION 5.02. Maintenance, Repairs, Replacements and Depreciation Reserve.

The Company shall at all times maintain, preserve and keep or cause to be maintained, preserved and kept the Mortgaged Property, and every part thereof, with the appurtenances and every part and parcel thereof, in thorough repair, working order and condition, and from time to time make or cause to be made all needful and proper repairs and renewals, replacements and substitutions, and shall make adequate provision for replacement by proper and reasonable credits to its reserve for depreciation, so that at all times the value of the Mortgaged Property and the efficiency of the Mortgaged Property shall be fully preserved and maintained; and that it will comply with all lawful requirements of the PUC with respect to maintenance and depreciation.

SECTION 5.03. Consent to Waiver of Event of Default under Other Series of Bonds.

No Event of Default with respect to any series of Bonds Outstanding under the Base Indenture may be waived unless also waived by the Holders of not less than a majority in aggregate principal amount of the Outstanding Series CC Bonds by means of a written instrument or instruments signed by such Holders and delivered to the Trustee and the Company.

SECTION 5.04. Most Favored Nation Provision.

If the Company shall, at any time on or after the Closing Date, enter into, amend or modify any supplemental indenture or other agreement with respect to a series of Bonds in a manner that requires the Company to comply with or add a covenant, an event of default, a guarantee or collateral that either is not at such time applicable to the Series CC Bonds or, if such covenant, event of default, guarantee or collateral shall already be applicable to the Series CC Bonds, is, or contains related provisions that are, more restrictive upon the Company or

any guarantor hereof than such existing covenant, event of default, guarantee or related provisions, each provision (including any related definitions) relating to such covenant, event of default, guarantee or security in such supplemental indenture (as amended or modified from time to time thereafter) shall be automatically deemed to be incorporated by reference in this Supplemental Indenture, mutatis mutandis, as if then set forth herein in full. Promptly after any such execution, amendment or modification of such a supplemental indenture, the Company shall (a) furnish to the Trustee a copy of each such supplemental indenture, (b) execute and deliver to the Trustee a supplemental indenture in form and substance reasonably satisfactory to the Holders of at least a majority in aggregate principal amount of the Series CC Bonds, amending or modifying this Supplemental Indenture by adding or modifying, as the case may be, the full text of such covenant, event of default, guarantee, definitions and other related provisions and (c) furnish to the Trustee any certificates and opinions required by clause (1) of Section 3.08 and Section 15.01 of the Base Indenture.

(vi) Promptly after receipt, copies of any report as to material inadequacies in accounting controls (including reports as to the absence of any such inadequacies) submitted by independent accountants in connection with any audit of Parent.

(vii) Promptly after any officer of the Company obtains knowledge of a Default under the Base Indenture or under this Supplemental Indenture, a certificate signed by the President or a Vice President and the Treasurer or Assistant Treasurer of the Company describing such event in reasonable detail, with a statement of the Company’s action with respect thereto taken or proposed.

“Remaining Scheduled Payments” means, with respect to the Called Principal of any Series CC Bond, all payments of such Called Principal and interest thereon that would be due after the Settlement Date with respect to such Called Principal if no payment of such Called Principal were made prior to its scheduled due date, provided that if such Settlement Date is not a date on which interest payments are due to be made under the terms of the Series CC Bonds, then the amount of the next succeeding scheduled interest payment will be reduced by the amount of interest accrued to such Settlement Date and required to be paid on such Settlement Date pursuant to Article III of the Supplemental Indenture or under Section 7.01 of the Base Indenture, as the context requires.

13. AMENDMENT, WAIVER

The Base Indenture permits, subject to certain exceptions set forth therein, that the Base Indenture and the terms of the Bonds of a series, which include the Series CC Bonds, and the rights of the Holders of the Bonds of a series, which may include the Holders of the Series CC Bonds, in each case may be modified, with the written consent of the Holders of a majority in aggregate principal amount of the Bonds the terms of which or the rights of the Holders of which are to be modified. The Base Indenture also permits certain other amendments, modifications or waivers thereof only with the consent of each Outstanding Bond affected thereby, while certain other amendments or modifications may be made without the consent of any Holders of Bonds.

The Base Indenture also provides the Holders of sixty-six and two-thirds percent (66-2/3%) or more of principal amount of the Bonds then Outstanding of all such series under which an Event of Default shall have occurred, which may include the Series CC Bonds, may, by a written instrument or instruments signed by such Holders and delivered to the Trustee and to the Company, waive any past Default or Event of Default under such series of Bonds and its consequences except an Event of Default in the payment of the principal of, premium, if any, or interest on any of the Bonds as and when the same shall become due by the terms of such Bonds, and upon such waiver such Default or Event of Default shall be deemed not to exist for any purpose of the Base Indenture or such series of Bonds.

Any such consent or waiver by the Holder of this Series CC Bond shall be conclusive and binding upon such Holder and upon all future Holders of this Series CC Bond and of any Series CC Bond issued in lieu of or exchange, in respect of anything done, omitted or suffered by the Trustee in pursuance thereof.

14. DEFAULTS AND REMEDIES

Events of Default are set forth in the Base Indenture and the Supplemental Indenture. If an Event of Default shall have occurred and be continuing, the Trustee upon the direction of Holders of not less than twenty-five percent (25%) aggregate principal amount of the Outstanding Bonds or the Holders of not less than twenty-five percent (25%) aggregate principal amount of the Outstanding Bonds, may, by notice in writing delivered to

A-7

the Company (and to the Trustee if given by the Holders), declare the entire principal amount of Outstanding Bonds, Make-Whole Amount, if any, and the interest accrued thereon immediately due and payable, and said entire principal, Make-Whole Amount, if any, and interest shall thereupon become and be immediately due and payable.

Holders may not enforce the the Base Indenture, the Supplemental Indenture or the Series CC Bonds except as provided in the Base Indenture. The Trustee may refuse to enforce the Base Indenture, the Supplemental Indenture or the Series CC Bonds unless it receives indemnity or security reasonably satisfactory to it. Subject to certain limitations, Holders of a majority in aggregate principal amount of the Outstanding Bonds may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders notice of any Default (except a Default in payment of principal or interest on any Bond, or in the payment of any sinking fund installment) if and so long as Responsible Officers in good faith determine that withholding notice is in the interest of the Holders.

15. TRUSTEE DEALINGS WITH THE COMPANY

Subject to certain limitations imposed by the TIA, the Trustee, in its individual or any other capacity, may become the owner or pledgee of the Series CC Bonds and may otherwise deal with and collect obligations owed to it by the Company or its Affiliates and may otherwise deal with the Company or its Affiliates with the same rights it would have if it were not Trustee.

16. NO PERSONAL LIABILITY OF DIRECTORS, OFFICERS, EMPLOYEES AND STOCKHOLDERS

No director, officer, employee, incorporator or stockholder of the Company or Parent shall have any liability for any obligations of the Company under the Base Indenture, the Supplemental Indenture or the Series CC Bonds or for any claim based on, in respect of, or by reason of such obligations or their creation. Each Holder by accepting the Series CC Bonds waives and releases all such liability. The waiver and release are part of the consideration for the issuance of the Series CC Bonds. Such waiver may not be effective to waive liabilities of directors, officers or persons controlling the Company under the federal securities laws and it is the view of the Commission that such waiver is against public policy and is therefore unenforceable.

17. GOVERNING LAW

The Series CC Bonds shall be governed by, and construed and enforced in accordance with, the laws of the State of California without regard to the principles of conflicts of laws thereunder, except to the extent that the TIA shall be applicable.

18. AUTHENTICATION

GUARANTEE, dated as of (as amended from time to time, this “Guarantee”), made by California Water Service Group, a Delaware corporation (the “Guarantor”), in favor of U.S. Bank National Association, as trustee (“Trustee”) for the registered holders (the “Holders”) of the 9.86% First Mortgage Bonds due 2020, Series CC (collectively, the “Bonds”), of California Water Service Company, a California corporation (the “Issuer”).

WITNESSETH:

SECTION 1. Guarantee. (a) The Guarantor hereby fully, absolutely, irrevocably and unconditionally guarantees the due and punctual payment when due, whether at stated maturity, by acceleration, by notice of prepayment or otherwise, of the principal of, premium, if any, and interest on the Bonds (the “Obligations”), according to the terms of the Bonds and as more fully described in the Indenture dated as of April 1, 1928 (as amended, modified or otherwise supplemented from time to time, including the Thirty-ninth Supplemental Indenture and the Fortieth Supplemental Indenture, the “Indenture”), between the Issuer and the Trustee, and any other amounts payable by the Guarantor to the Holders under the Indenture. The Guarantor’s obligation to make payment on the Obligations may be satisfied by direct payment of the required full and final amounts by the Guarantor to the Holders or by causing the Issuer to pay such full and final amounts to the Holders.

(b) It is the intention of the Guarantor that this Guarantee not constitute a fraudulent transfer or conveyance for purposes of Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal or state law to the extent applicable to this Guarantee. To effectuate the foregoing intention, the amount guaranteed by the Guarantor under this Guarantee shall be limited to the maximum amount as will, after giving effect to such maximum amount and all other contingent and fixed liabilities of the Guarantor that are relevant under such laws, result in the Obligations of the Guarantor under this Guarantee not constituting a fraudulent transfer or conveyance. For purposes hereof, “Bankruptcy Law” means Title 11, U.S. Code, or any similar federal or state law for the relief of debtors.

SECTION 2. Guarantee Absolute. The Guarantor guarantees that the Obligations will be paid strictly in accordance with the terms of the Indenture, regardless of any law, regulation or order now or hereafter in effect in any jurisdiction affecting any of such terms or the rights of Holders of the Bonds with respect thereto. The Guarantor assents to all the terms, covenants and conditions of the Bonds and the Indenture. The liability of the Guarantor under this Guarantee shall be full, absolute, irrevocable and unconditional irrespective of:

(a) any lack of validity, enforceability or genuineness of any provision of the Indenture, the Bonds or any other agreement or instrument relating thereto;

(b) any change in the time, manner or place of payment of, or in any other term of, all or any of the Obligations, or any other amendment or waiver of or any consent to departure from the Indenture;

(c) any exchange, release or non-perfection of any collateral, or any release or amendment or waiver of or consent to departure from any other guarantee, for all or any of the Obligations;

(d) the recovery of any judgment against the Issuer, or by the levy of any writ or process of execution under such judgment, or by any action or proceedings taken by any Holder under the Indenture, the Bonds or the Guarantee for the enforcement thereof or hereof;

(e) the consolidation or merger of the Issuer with or into any other corporation or any sale, lease or other disposition of the Issuer’s properties as an entirety or substantially as an entirety to any other corporation;

(f) the release or waiver, by operation of law or otherwise, of the performance or observance by the Issuer of any express or implied agreement, covenant, term or condition relating to the Bonds to be performed or observed by the Issuer;

B-1

(g) the extension of time for the payment by the Issuer of any portion of the Obligations (other than an extension of time for payment of Obligations that results from the extension of any interest payment period on the Bonds as provided in the Indenture), or the extension of time for the performance of any other obligation under, arising out of, or in connection with, the Bonds;

(h) any failure, omission, delay or lack of diligence on the part of the Holders to enforce, assert or exercise any right, privilege, power or remedy conferred on the Holders pursuant to the terms of the Bonds, or any action on the part of the Issuer granting indulgence or extension of any kind;

(i) the voluntary or involuntary liquidation, dissolution, receivership, insolvency, bankruptcy, assignment for the benefit of creditors, reorganization, arrangement, composition or readjustment of debt of, or other similar proceedings affecting, the Issuer or any of the assets of the Issuer;

(j) any invalidity of, or defect or deficiency in, the Bonds;

(k) the settlement or compromise of any obligation guaranteed hereby or hereby incurred; or

(l) any other circumstance whatsoever that might otherwise constitute a legal or equitable discharge or defense of a guarantor (other than payment of the underlying obligation) and any other act or delay or failure to act, or by any other thing, which may or might in any manner or to any extent vary the risk of the Guarantor, it being the intent of this Section 2 that the obligations of the Guarantor hereunder shall be absolute and unconditional under any and all circumstances.

There shall be no obligation of the Holders to give notice to, or obtain the consent of, the Guarantor with respect to the happening of any of the foregoing.

SECTION 3. Subordination. The Guarantor covenants and agrees that its obligation to make payments of the Obligations hereunder constitutes an unsecured obligation of the Guarantor ranking (a) pari passu with all existing and future senior indebtedness of the Guarantor and (b) senior in right of payment to all existing and future subordinated indebtedness of the Guarantor.

SECTION 4. Waiver; Subrogation. (a) The Guarantor hereby irrevocably waives promptness, diligence, notice of acceptance, notice of nonpayment, notice of dishonor, notice of redemption, notice of Event of Default and any other notice with respect to this Guarantee, presentment, demand for payment or protest and all other demands and related notices, and any requirement that the Trustee, or the Holders of any Bonds protect, secure, perfect or insure any security interest or lien or any property subject thereto or exhaust any right or take any action against the Issuer or any other Person or any collateral.

(b) The Guarantor hereby irrevocably waives any claims or other rights that it may now or hereafter acquire against the Issuer that arise from the existence, payment, performance or enforcement of the Guarantor’s obligations under this Guarantee or the Indenture, including, without limitation, any right of subrogation, reimbursement, exoneration, contribution or indemnification and any right to participate in any claim or remedy of the Trustee, or the Holders of any Bonds against the Issuer or any collateral, whether or not such claim, remedy or right arises in equity or under contract, statute or common law, including, without limitation, the right to take or receive from the Issuer, directly or indirectly, in cash or other property or by set-off or in any other manner, payment or security on account of such claim, remedy or right. If any amount shall be paid to the Guarantor in violation of the preceding sentence at any time prior to the cash payment in full of the Obligations and all other amounts payable under this Guarantee, such amount shall be held in trust for the benefit of the Trustee and the Holders of any Bonds and shall forthwith be paid to the Trustee, to be credited and applied to the Obligations and all other amounts payable under this Guarantee, whether matured or unmatured, in accordance with the terms of the Indenture and this Guarantee, or be held as collateral for any Obligations or other amounts payable under this Guarantee thereafter arising.

(c) Guarantor further waives any and all rights and defenses that Guarantor may have because Issuer’s debt is secured by real property; this means, among other things, that: (1) Guarantor waives any such defenses that may arise out of an election of remedies by Trustee, even though that election of remedies, such as a nonjudicial foreclosure with respect to security for a guaranteed obligation, has destroyed Guarantor’s rights of subrogation and reimbursement against the principal by the operation of Section 580d of the California Code of Civil Procedure or otherwise; (2) Trustee may collect from Guarantor without first foreclosing on any real or personal property collateral pledged by Issuer; (3) if Trustee forecloses on any real property collateral pledged by Issuer,

B-2

then (A) the amount of the debt may be reduced only by the price for which that collateral is sold at the foreclosure sale, even if the collateral is worth more than the sale price, and (B) Trustee may collect from Guarantor even if Trustee, by foreclosing on the real property collateral, has destroyed any right Guarantor may have to collect from Issuer. The foregoing sentence is an unconditional and irrevocable waiver of any rights and defenses Guarantor may have because Issuer’s debt is secured by real property. These rights and defenses being waived by Guarantor include, but are not limited to, any rights or defenses based upon Section 580a, 580b, 580d or 726 of the California Code of Civil Procedure. Without limiting the generality of the foregoing or any other provision hereof, Guarantor further expressly waives to the extent permitted by law any and all rights and defenses, including without limitation any rights of subrogation, reimbursement, indemnification and contribution, which might otherwise be available to Guarantor under California Civil Code Sections 2787 to 2855, inclusive, 2899 and 3433, or under California Code of Civil Procedure Sections 580a, 580b, 580d and 726, or any of such sections.

(d) The Guarantor acknowledges that it will receive direct and indirect benefits from the financing arrangements contemplated by the Indenture and this Guarantee and that the waiver set forth in this Section 4 is knowingly made in contemplation of such benefits.

SECTION 5. Rights of Holders. The Guarantor expressly acknowledges that: (i) this Guarantee will be deposited with the Trustee to be held for the benefit of the Holders; (ii) the Trustee has the right to enforce this Guarantee on behalf of the Holders; and (iii) the Holders of a majority in principal amount of the Bonds have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee in respect of this Guarantee or exercising any trust or power conferred upon the Trustee under this Guarantee.

SECTION 6. Independent Obligations. The Guarantor acknowledges that its obligations hereunder are independent of the obligations of the Issuer with respect to the Bonds and that the Guarantor shall be liable as principal and as debtor hereunder to pay the Obligations pursuant to the terms of this Guarantee.

SECTION 7. No Waiver; Remedies. No failure on the part of the Trustee or any Holder of the Bonds to exercise, and no delay in exercising, any right hereunder shall operate as a waiver thereof; nor shall any single or partial exercise of any right hereunder preclude any other or further exercise thereof or the exercise of any other right. The remedies herein provided are cumulative and not exclusive of any remedies provided by law.

SECTION 8. Guarantee of Payment; Continuing Guarantee; Transfer of Interest. This Guarantee creates a guarantee of payment.
