Authorization of Bonds. There shall be issued under and secured by this Indenture a single series of Bonds to be designated as "California Economic Development Financing Authority Variable Rate Demand Industrial Development Revenue Bonds, Series 1997 (Advanced Aerodynamics and Structures, Inc. Project)" in the original principal amount of $8,500,000, to be dated as of the Date of Delivery, and to mature fully (subject to prior redemption at the prices and dates and upon the terms and conditions hereinafter set forth) on August 1, 2027. SECTION 2.02. Terms of the Bonds. (A) The Bonds shall be issued as fully registered Bonds without coupons in the Authorized Denominations. The Bonds shall be in substantially the form set forth in Exhibit A hereto. (B)(1) Each Bond shall bear interest at the rates determined pursuant to Section 2.02(C) and 2.03(B) from and including the Interest Payment Date next preceding the date of registration thereof (unless such Bond is registered after a Record Date and on or before the next succeeding Interest Payment Date or on an Interest Payment Date, in which event it shall bear interest from and including such Interest Payment Date, or unless such Bond is registered on or prior to September 1, 1997, in which event it shall bear interest from and including the Date of Delivery), payable on each Interest Payment Date. The interest so payable on any Interest Payment Date will be paid on the Interest Payment Date to the Persons in whose name the Bonds are registered at the close of business of the Bond Registrar on the Record Date for such Interest Payment Date; except as provided below. (2) Any such interest not so punctually paid or duly provided for shall forthwith cease to be payable to the Holder as of the Record Date for such payment of interest, and shall be paid to the Person in whose name the Bond is registered at the close of business on a Special Record Date for the payment of such defaulted interest, to be fixed by the Trustee, notice thereof being given to the Holders not less than ten (10) days prior to such Special Record Date. (3) Interest shall be paid in lawful money of the United States by check or draft mailed to each Holder at the address shown on the registration books maintained by the Bond Registrar pursuant to Section 2.07; provided, however, interest may also be paid by wire transfer to an address in the continental United States in the case of a Holder of at least $1,000,000 aggregate principal amount of Bonds upon written request of the Holder thereof 15 days prior to the applicable Record Date to the Bond Registrar in a form satisfactory to the Bond Registrar. (C)(1) The Bonds shall bear interest until payment of the principal thereof and interest thereon shall have been made or provided for in accordance with the provisions hereof, whether at maturity, upon redemption or otherwise. Prior to the Fixed Rate Date, interest shall be computed on the basis of a year of 365 or 366 days, as appropriate, for the actual number of days elapsed. The Bonds shall bear interest for each day from and including the Date of Delivery until the Fixed Rate Date or final maturity date, whichever is earlier, at the Weekly Interest Rate; provided that appropriate adjustments may be made for the initial period following the Date of Delivery. The Weekly Interest Rate shall be the rate determined by the Remarketing Agent (on the basis of the examination of Tax-exempt obligations comparable to the Bonds known by the Remarketing Agent to have been priced or traded under then prevailing market conditions) to be the minimum interest rate which, if borne by the Bonds, would enable the Remarketing Agent to sell the Bonds on the date such 16 rate becomes effective at a price equal to the principal amount thereof, plus accrued interest, if any, but in no event exceeding twelve percent (12%) per annum. The Weekly Interest Rate shall be determined by the Remarketing Agent as of the close of business on Tuesday in each calendar week until the earlier of the Fixed Rate Date or payment in full of the Bonds; provided that, if Tuesday in any calendar week shall not be a Business Day, then such determination shall be made on the next preceding Business Day; and provided further that appropriate adjustments may be made for the initial period following the Date of Delivery. The Weekly Interest Rate shall be effective from Wednesday in the week of determination thereof to and including the following Tuesday irrespective of when the rate was determined by the Remarketing Agent; provided that appropriate adjustments may be made for the initial period following the Date of Delivery. The Weekly Interest Rate shall be communicated by telephonic notice, promptly confirmed in writing, by the Remarketing Agent to the Trustee on the Business Day next following the day on which the Weekly Interest Rate is determined. The Remarketing Agent shall also give written notice to the Tender Agent, the Bank and the Borrower of the Weekly Interest Rate at the time it gives the aforesaid written confirmation thereof to the Trustee. If for any reason the Remarketing Agent does not determine the Weekly Interest Rate in any week, the Weekly Interest Rate for the first such week in which the Remarketing Agent does not determine the Weekly Interest Rate shall remain at the last Weekly Interest Rate announced by the Remarketing Agent and the Weekly Interest Rate thereafter shall be 90% of the "Alternate Weekly Rate" (as defined below). (2) If on any date on which the Weekly Interest Rate is determined, the Weekly Interest Rate determined in accordance with paragraph (1) of this paragraph (C) is held by a court to be invalid or unenforceable, then the Weekly Interest Rate shall be 90% of the Alternate Weekly Rate. The "Alternate Weekly Rate" shall be the A-1/P-1 30-day commercial paper rate as determined by the Remarketing Agent. (3) Each determination of the Weekly Interest Rate by the Remarketing Agent shall be conclusive and binding on the Holders, the Trustee and the Authority. The Trustee shall calculate the amount of interest due on each Interest Payment Date with respect to the then-concluding Interest Period by the close of business on the date one (1) Business Day prior to the end of such Interest Period, and shall notify the Borrower and the Bank of such amount. The Trustee shall inform any Bondholder who requests the same of the Weekly Interest Rate in effect from time to time. (4) Anything herein to the contrary notwithstanding, in no event shall the interest rate borne by the Bonds exceed twelve percent (12%) per annum or, if lower, the maximum rate of interest which may be charged or collected pursuant to applicable provisions of federal or state law. (D) The principal of the Bonds shall be payable in lawful money of the United States of America on August 1, 2027 at the principal corporate trust office of the Trustee in San Francisco, California or at such other office as the Trustee may designate. Except as provided in Section 2.09, no payment of principal shall be made on any Bond unless and until such Bond is tendered to the Trustee for cancellation, as the case may be. (E) The Bonds shall be subject to redemption and purchase as provided in Article IV. SECTION 2.03. Conversion of Bonds. (A) On any Interest Payment Date, the interest rate on the Bonds may be converted to a fixed annual rate of interest upon receipt by the Authority, the Trustee, the Tender Agent, the Bank and the Remarketing Agent not less than 45 days in advance of the proposed Fixed Rate Date of (i) notice from the Borrower electing to have the interest rate on the Bonds 17 converted to a fixed rate of interest and the effective date of such conversion, (ii) an opinion of Bond Counsel (which shall be confirmed on the Fixed Rate Date) to the effect that conversion to a Fixed Interest Rate is permitted by the Indenture and the Act, that conversion to the Fixed Interest Rate in accordance with the provisions of the Indenture will not cause interest on the Bonds to not be Tax-exempt and that, to the extent required, the Borrower has complied with the Disclosure Requirements as provided in Section 5.12 of the Agreement, (iii) receipt by the Trustee of a commitment from the Bank evidencing that the Letter of Credit has been increased to provide for the interest, principal and premium requirements on the Bonds on and after the Fixed Rate Date or an Alternate Credit Facility pursuant to the terms of Section 5.7 of the Agreement or an Alternate Letter of Credit pursuant to the terms of Section 5.8 of the Agreement, (iv) the written consent of the Bank to such conversion and (v) receipt by the Trustee of written evidence from the rating agency then rating the Bonds of its rating on the Bonds. (B)(1) After the Fixed Rate Date, interest on the Bonds shall be computed on the basis of a year of 360 days and 12 months of 30 days each. The interest rate on all Bonds from the Fixed Rate Date until the maturity or prior redemption or acceleration thereof shall be a rate per annum equal to the Fixed Interest Rate, which shall be determined on or prior to, but not more than 15 days prior to, the Business Day immediately preceding the Fixed Rate Date. The Remarketing Agent shall specify the Fixed Interest Rate to be borne by the Bonds on and after the Fixed Rate Date. The Fixed Interest Rate shall be the rate, but not exceeding the rate, which at the time of determination thereof in the judgment of the Remarketing Agent, having due regard for prevailing financial market conditions, would be necessary to remarket the Bonds at a price equal to 100% of the principal amount thereof on the Fixed Rate Date. If on the date of determination by the Remarketing Agent of the Fixed Interest Rate, the Fixed Interest Rate so determined is held by a court to be invalid or unenforceable, then the Fixed Interest Rate shall be a rate determined by the Remarketing Agent, not less than 90% or more than 130% of the "Alternate Fixed Rate," which in the judgment of the Remarketing Agent, having due regard for prevailing market conditions, would be the minimum rate at which Holders of the Bonds would be able to sell the Bonds at a price equal to the principal amount thereof on the Fixed Rate Date. The Alternate Fixed Rate shall be determined by the Remarketing Agent and shall be a rate per annum based upon yield evaluations at par of Tax-exempt securities having a remaining term equal, as nearly as practicable, to the time remaining until the maturity of the Bonds of not less than five Component Issues selected by the Remarketing Agent each of which would be rated by either Moody's or S&P in a long-term debt rating category which is the same as, or is immediately proximate to, the long-term debt rating category which will be assigned to the Bonds after the Fixed Rate Date. Anything to the contrary herein notwithstanding, the Fixed Interest Rate shall not exceed twelve percent (12%) per annum. If, after the Fixed Rate Date, the Bonds shall fail to be converted to a Fixed Interest Rate, the Bonds will continue to earn interest at the Weekly Interest Rate as provided in this Indenture and the Holders shall be notified thereof by the Trustee. (2) Following an election of the Borrower to convert the interest rate on the Bonds to the Fixed Interest Rate as provided in this Section 2.03, the Holders of all of the Outstanding Bonds shall be required to tender their Bonds for purchase on the Mandatory Tender Date. (3) At least thirty (30) days prior to the Fixed Rate Date, the Trustee shall give an irrevocable notice to the Bondholders of conversion of the Weekly Interest Rate borne by the Bonds to the Fixed Interest Rate on the Fixed Rate Date. If a Bondholder delivers a written request to the Trustee at least 45 days prior to the Fixed Rate Date setting forth the appropriate telex or telecopier number and other necessary information to enable the Trustee to deliver such notice by telegram, telex, telecopier or other telecommunication device capable of creating a written notice such notice shall be delivered in the manner requested. Such notice shall (i) specify the proposed Fixed Rate Date, (ii) require the Holders of all of the Outstanding Bonds to tender their Bonds for purchase on the Mandatory Tender Date 18 pursuant to Section 4.07, and (iii) state that all Outstanding Bonds not purchased on or before the Mandatory Tender Date will be deemed to be purchased on the Mandatory Tender Date at a price equal to the principal amount thereof, plus unpaid interest, if any, accrued to such date. (4) Any Bond purchased by the Tender Agent pursuant to the provisions of Section 4.06 hereof from the date notice of the proposed Fixed Rate Date is given to Bondholders through the Fixed Rate Date shall be remarketed at the Weekly Interest Rate for a period of time up to and including the Fixed Rate Date; provided, however, that all Bonds remarketed from the date notice of the proposed Fixed Rate Date is given to Bondholders through the Fixed Rate Date shall be tendered by the Holders thereof for purchase on the Mandatory Tender Date. (5) The determination of the Fixed Interest Rate by the Remarketing Agent shall be conclusive and binding on the Authority, the Trustee, the Borrower and the Holders of the Bonds. SECTION 2.04. Execution of Bonds. The Bonds shall be executed in the name and on behalf of the Authority with the manual or facsimile signature of the Chair of the Authority or the Chair's designee and attested by the manual or facsimile signature of its Secretary. The Bonds shall then be delivered to the Bond Registrar for authentication by it. In case any of the officers who shall have signed or attested any of the Bonds shall cease to be such officer or officers of the Authority before the Bonds so signed or attested shall have been authenticated or delivered by the Bond Registrar or issued by the Authority, such Bonds may nevertheless be authenticated, delivered and issued and, upon such authentication, delivery and issue, shall be as binding upon the Authority as though those who signed and attested the same had continued to be such officers of the Authority, and also any Bonds may be signed and attested on behalf of the Authority by such persons as at the actual date of execution of such Bonds shall be the proper officers of the Authority although at the nominal date of such Bonds any such person shall not have been such officer of the Authority. Only such of the Bonds as shall bear thereon a certificate of authentication substantially in the form set forth in Exhibit A, with the manual signature of the Bond Registrar, shall be valid or obligatory for any purpose or entitled to the benefits of this Indenture, and such certificate of the Bond Registrar shall be conclusive evidence that the Bonds so authenticated have been duly executed, authenticated and delivered hereunder and are entitled to the benefits of this Indenture. SECTION 2.05. Transfer of Bonds. Any Bond may, in accordance with its terms, be transferred, upon the books required to be kept pursuant to the provisions of Section 2.07, by the person in whose name it is registered, in person or by his duly authorized attorney, upon surrender of such registered Bond for cancellation, accompanied by delivery of a written instrument of transfer, duly executed in a form approved by the Bond Registrar. Transfer of a Bond shall not be permitted by the Bond Registrar: (i) if the Bond Registrar has received notice from the Holder of such Bond that such Bond will be delivered to the Tender Agent for purchase on or before the next succeeding Interest Payment Date or (ii) if the Bond Registrar receives such written instrument of transfer after the Record Date prior to the next succeeding Interest Payment Date. Whenever any Bond or Bonds shall be surrendered for transfer, the Authority shall execute and the Bond Registrar shall authenticate and deliver a new Bond or Bonds for a like aggregate principal amount in an Authorized Denomination. The Bond Registrar shall require the Bondholder requesting such transfer to pay any tax or other governmental charge required to be paid with respect to such transfer, and may in addition require the payment of a reasonable sum to cover expenses incurred by the Authority and the Bond Registrar in connection with such transfer. 19 Notwithstanding the foregoing, prior to the Fixed Rate Date, no Bonds held by or for the account of the Bank or the Borrower shall be transferred upon the books required to be kept pursuant to Section 2.07 hereof unless the Trustee has received positive affirmation that the Bank has received all reimbursements then due under the Reimbursement Agreement and the Trustee has notified the Tender Agent in writing of such reimbursement, so that the amount that may be drawn under the Letter of Credit shall have been, or shall concurrently with such transfer be, reinstated (automatically or otherwise), in the amount of the draw on the Letter of Credit used to purchase such Bonds proposed to be transferred. SECTION 2.06. Exchange of Bonds. Bonds may be exchanged at the principal corporate trust office of the Trustee in San Francisco, California, or at such other office as the Trustee may designate, for a like aggregate principal amount of Bonds of other Authorized Denominations. The Bond Registrar shall require the Bondholder requesting such exchange to deliver such Bonds to be exchanged and to pay any tax or other governmental charge required to be paid with respect to such exchange, and may in addition require the payment of a reasonable sum to cover expenses incurred by the Authority or the Bond Registrar in connection with such exchange. Thereupon, the Bonds delivered to the Bond Registrar for exchange shall be cancelled by the Bond Registrar. SECTION 2.07. Bond Register. The Trustee is hereby designated and appointed as the bond registrar (the "Bond Registrar"). The Bond Registrar will keep or cause to be kept at its corporate trust office in San Francisco, California, or at such other office as the Bond Registrar may designate, sufficient books for the registration and transfer of the Bonds, and shall keep or cause to be kept within the State a copy of such books, which shall at all times be open to inspection during regular business hours by the Authority; and, upon presentation for such purpose, the Bond Registrar shall, under such reasonable regulations as it may prescribe, register or transfer or cause to be registered or transferred, on such books, Bonds as hereinbefore provided. SECTION 2.08. Temporary Bonds. The Bonds may be issued in temporary form exchangeable for definitive Bonds when ready for delivery. Any temporary Bond may be printed, lithographed or typewritten, shall be in an Authorized Denomination, shall be in fully registered form without coupons and may contain such reference to any of the provisions of this Indenture as may be appropriate and in a form acceptable to the Paying Agent. Every temporary Bond shall be executed by the Authority and be authenticated by the Bond Registrar upon the same conditions and in substantially the same manner as the definitive Bonds. If the Authority issues temporary Bonds it will execute and deliver definitive Bonds as promptly thereafter as practicable, and thereupon the temporary Bonds may be surrendered, for cancellation, in exchange therefor at the principal corporate trust office of the Bond Registrar and the Bond Registrar shall authenticate and deliver in exchange for such temporary Bonds an equal aggregate principal amount of definitive Bonds in Authorized Denominations. Until so exchanged, the temporary Bonds shall be entitled to the same benefits under this Indenture as definitive Bonds authenticated and delivered hereunder. SECTION 2.09. Bonds Mutilated, Lost, Destroyed or Stolen. If any Bond shall become mutilated, the Authority, at the expense of the Holder of said Bond, shall execute, and the Bond Registrar shall thereupon authenticate and deliver, a new Bond of like tenor in exchange and substitution for the Bond so mutilated, but only upon surrender to the Bond Registrar of the Bond so mutilated. Every mutilated Bond so surrendered to the Bond Registrar shall be cancelled by it and delivered to, or upon the order of, the Authority. If any Bond shall be lost, destroyed or stolen, evidence of such loss, destruction or theft may be submitted to the Bond Registrar and, if such evidence be satisfactory to it and indemnity satisfactory to the Bond Registrar shall be given, the Authority, at the expense of the Holder, shall execute, and the Bond Registrar shall thereupon authenticate and deliver, a new Bond of like tenor in lieu of and in substitution for the Bond so lost, destroyed or stolen (or if any such Bond shall have 20 matured or shall be about to mature, instead of issuing a substitute Bond, the Bond Registrar may pay the same without surrender thereof upon such maturity date). The Bond Registrar may require payment by the Holder of a sum not exceeding the actual cost of preparing each new Bond issued under this Section and of the expenses which may be incurred by the Authority and the Bond Registrar in the premises. Any Bond issued under the provisions of this Section in lieu of any Bond alleged to be lost, destroyed or stolen shall constitute an original additional contractual obligation on the part of the Authority whether or not the Bond so alleged to be lost, destroyed or stolen be at any time enforceable by anyone, and shall be entitled to the benefits of this Indenture with all other Bonds secured by this Indenture. SECTION 2.10. Special Obligations. The Bonds, together with the interest and premium (if any) thereon and the purchase price thereof, shall not be deemed to constitute a debt or liability of the State or any political subdivision or agency of the State or a pledge of the faith and credit of the State or any political subdivision or agency of the State, but shall be payable solely from the funds provided therefor pursuant to this Indenture. The Bonds are only a special obligation of the Authority as provided by the Act and the Authority shall under no circumstances be obligated to pay the Bonds or respective Costs of the Project except from Revenues and other funds pledged therefor. Neither the faith and credit nor the taxing power of the State or any political subdivision or agency of the State is pledged to the payment of the principal of, premium, if any, purchase price of or interest on the Bonds nor is the State or any political subdivision or agency of the State in any manner obligated to make any appropriation for such payment. The Authority has no taxing power. SECTION 2.11. Book-Entry Only System. (A) Except as otherwise provided in subsections (B) and (C) of this Section 2.11, the Bonds initially authenticated and delivered hereunder shall be registered in the name of Cede & Co., as nominee of DTC or such other nominee as DTC shall request. Payments of interest on, principal of and any premium on the Bonds shall be made to the account of Cede & Co. on each Bond Payment Date at the address indicated for Cede & Co. in the registration books maintained by the Bond Registrar by transfer of immediately available funds. DTC has represented to the Authority that it will maintain a book-entry system in recording ownership interests of its participants (the "Direct Participants") and the ownership interests of a purchaser of a beneficial interest in the Bonds (a "Beneficial Owner") will be recorded through book entries on the records of the Direct Participants. (B) The Bonds shall be initially issued in the form of a separate single authenticated fully registered Bond in the amount of each separate stated maturity. With respect to Bonds so registered in the name of Cede & Co., the Authority, the Trustee and the Tender Agent shall have no responsibility or obligation to any Direct Participant or to any Beneficial Owner of such Bonds. Without limiting the immediately preceding sentence, the Authority, the Trustee and the Tender Agent shall have no responsibility or obligation with respect to (i) the accuracy of the records of DTC, Cede & Co. or any Direct Participant with respect to any beneficial ownership interest in the Bonds, (ii) the delivery to any Direct Participant, Beneficial Owner or other person, other than DTC, of any notice with respect to the Bonds, including any notice of redemption, (iii) the payment to any Direct Participant, Beneficial Owner or other person, other than DTC, of any amount with respect to the principal or redemption price of, or interest on, the Bonds or (iv) any consent given or other action taken by DTC as Holder of the Bonds. The Authority, the Trustee and the Tender Agent may treat DTC as, and deem DTC to be, the absolute Holder of each Bond for all purposes whatsoever including (but not limited to) (i) payment of the principal or redemption price of, and interest on, each such Bond, (ii) giving notices of conversion or redemption and other matters with respect to such Bonds and (iii) registering transfers with respect to such Bonds. The Trustee shall pay the principal or redemption price of, and interest on, all Bonds only 21 to or upon the order of DTC, and all such payments shall be valid and effective to fully satisfy and discharge the Authority's obligations with respect to such principal or redemption price, and interest, to the extent of the sum or sums so paid. No person other than DTC shall receive a Bond evidencing the obligation of the Authority to make payments of principal or redemption price of, and interest on, the Bonds pursuant to this Indenture. Upon delivery by DTC to the Trustee of written notice to the effect that DTC has determined to substitute a new nominee in place of Cede & Co., and subject to the transfer provisions hereof, the word "Cede & Co." in this Indenture shall refer to such new nominee of DTC. (C) (1) DTC may determine to discontinue providing its services with respect to the Bonds at any time by giving reasonable written notice to the Authority, the Trustee and the Tender Agent and discharging its responsibilities with respect thereto under applicable law. (2) The Authority, in its sole discretion and without the consent of any other person, may terminate, upon provision of notice to the Trustee and Tender Agent, the services of DTC with respect to the Bonds if the Authority determines that the continuation of the system of book-entry only transfers through DTC (or a successor securities depository) is not in the best interests of the Beneficial Owners of the Bonds or is burdensome to the Authority, and shall terminate the services of DTC with respect to the Bonds upon receipt by the Authority, the Trustee and the Tender Agent of written notice from DTC to the effect that DTC has received written notice from Direct Participants having interests, as shown in the records of DTC, in an aggregate principal amount of not less than fifty percent (50%) of the aggregate principal amount of the then Outstanding Bonds to the effect, that: (i) DTC is unable to discharge its responsibilities with respect to such Bonds, or (ii) a continuation of the requirement that all of the Outstanding Bonds be registered in the registration books kept by the Trustee in the name of Cede & Co., as nominee of DTC, is not in the best interest of the Beneficial Owners of such Bonds. (D) Upon the termination of the services of DTC with respect to the Bonds pursuant to subsection (C)(2)(ii) hereof, or upon the discontinuance or termination of the services of DTC with respect to the Bonds pursuant to subsection (C)(1) or subsection (C)(2)(i) hereof after which no substitute securities depository willing to undertake the functions of DTC hereunder can be found or which, in the opinion of the Authority, is willing and able to undertake such functions upon reasonable and customary terms, the Bonds shall no longer be restricted to being registered in the registration books kept by the Bond Registrar in the name of Cede & Co. as nominee of DTC. In such event, the Authority shall issue and the Trustee shall transfer and exchange Bond certificates as requested by DTC or Direct Participants of like principal amount, series and maturity, in Authorized Denominations to the identifiable Beneficial Owners in replacement of such Beneficial Owners' beneficial interests in the Bonds. (E) Notwithstanding any other provision of this Indenture to the contrary, so long as any Bond is registered in the name of Cede & Co., as nominee of DTC, all payments with respect to the principal or redemption price of, and interest on, such Bond and all notices with respect to such Bond shall be made and given, respectively, to DTC. (F) In connection with any notice or other communication to be provided to Bondholders pursuant to this Indenture by the Authority, the Tender Agent or the Trustee with respect to any consent or other action to be taken by Bondholders, the Authority, the Tender Agent or the Trustee, as the case may be, shall establish a record date for such consent or other action and give DTC notice of such record date not less than fifteen (15) calendar days in advance of such record date to the extent possible. 22 (G) Notwithstanding any provision herein to the contrary, the Authority and the Trustee may agree to allow DTC, or its nominee, Cede & Co., to make a notation on any Bond redeemed in part to reflect, for informational purposes only, the principal amount and date of any such redemption. (H) Notwithstanding any provision herein to the contrary, so long as the Bonds are subject to a system of book-entry only transfers pursuant to this Section, any requirement for the delivery of Bonds to the Tender Agent in connection with a mandatory tender pursuant to Section 4.07 shall be deemed satisfied upon the transfer, on the registration books of DTC, of the beneficial ownership interests in such Bonds tendered for purchase to the account of the Tender Agent, or a Direct Participant acting on behalf of the Tender Agent. ARTICLE III ISSUANCE OF BONDS; APPLICATION OF PROCEEDS SECTION 3.01. Issuance of the Bonds. At any time after the execution of this Indenture, the Authority may execute and the Bond Registrar shall authenticate and, upon Request of the Authority, deliver Bonds in the aggregate principal amount set forth in Section 2.01. SECTION 3.02. Application of Proceeds of the Bonds. The proceeds received from the sale of the Bonds shall be deposited in trust with the Trustee, who shall forthwith set aside such proceeds as follows: (A) The Trustee shall set aside the sum of $170,000 in the Costs of Issuance Fund, together with any additional money supplied by the Borrower to pay the Costs of Issuance, which Costs of Issuance Fund the Trustee shall establish and maintain as further provided in Section 3.03(E) hereof. (B) The Trustee shall set aside the remainder of said proceeds, $8,330,000, in the Project Fund. SECTION 3.03. Establishment and Application of Project Fund and Costs of Issuance Fund. (A) The Trustee shall establish, maintain and hold in trust a separate fund designated as the "Project Fund." The moneys in the Project Fund shall be used and withdrawn by the Trustee to pay the Costs of the Project. (B) Subject to paragraph (C) of this Section 3.03, before any payment from the Project Fund shall be made to pay any Costs of the Project, the Borrower shall file or cause to be filed with the Trustee a Requisition of the Borrower stating (i) the item number of such payment; (ii) the name of the Person to whom each such payment is due, which may be the Borrower in the case of reimbursement for any Costs of the Project theretofore paid by the Borrower; (iii) the respective amounts to be paid; (iv) the purpose by general classification for which each obligation to be paid was incurred; (v) that obligations in the stated amounts are presently due and payable and that each item thereof is a proper charge against the Project Fund and has not been previously paid from said fund or from the proceeds of the Bonds; and (vi) that there has not been filed with or served upon the Borrower notice of any lien, or attachment upon, or claim affecting the right to receive payment of, any of the amounts payable to any of the persons named in such Requisition, which has not been released or will not be released simultaneously with the payment of such obligation, other than materialmen's or mechanics' liens accruing by mere operation of law. 23 Upon receipt of each Requisition, the Trustee shall pay the amount set forth in such Requisition as directed by the terms thereof out of the Project Fund. The Trustee may, upon satisfaction by the Borrower of the conditions set forth in this Section 3.03(B), pay each Requisition without the written approval of the Bank unless the Trustee has received written notice from the Bank that the payment of any subsequent Requisition requires the Bank's written approval. The Trustee shall not make any such payment if it has theretofore received notice of any lien, right to lien or attachment upon, or claim affecting the right to receive payment of, any of the moneys to be so paid, which has not been released or will not be released simultaneously with such payment. (C) In the event the Borrower elects to invest any moneys on deposit in the Project Fund in Permitted Investments other than Investment Securities pursuant to Section 5.05 of this Indenture, the Trustee shall, prior to the payment of any Requisition which would result in the amount remaining on deposit in the Project Fund being less than 2% of the principal amount of the Bonds set forth in Section 2.01, notify the Borrower that a rebate calculation is required to determine the Rebate Requirement (as defined in the Tax Regulatory Agreement) in accordance with Section 5.07 of this Indenture. In addition, the payment of such Requisition by the Trustee shall be subject to prior compliance with the provisions of Section 5.07 of this Indenture and the Tax Regulatory Agreement. (D) Subject to paragraph (C) of this Section 3.03, upon the receipt of the Certificate of the Borrower required by Section 3.3 of the Agreement, accompanied by the written approval of the Bank, or at such time that there are no Outstanding Bonds, the Trustee shall transfer any remaining balance in the Project Fund, less the amount of any such retention, to a separate account within the Redemption Account, which the Trustee shall establish and hold in trust, and which shall be entitled the "Surplus Account." The moneys in the Surplus Account shall be used and applied (unless some other application of such moneys would not, in the opinion of Bond Counsel, adversely affect the Tax-exempt status of interest on the Bonds) to pay principal only in connection with the call and redemption of Bonds to the maximum degree permissible in accordance with Section 4.01 hereof, and at the earliest possible dates at which Bonds can be redeemed without payment of premium pursuant to this Indenture or to reimburse the Bank for any draws theretofore made by the Trustee under the Letter of Credit, but not yet reimbursed, the proceeds of which were used to accomplish such redemption; provided, however, that the principal of Pledged Bonds shall be paid from moneys in the Surplus Account prior to the payment of principal of any other outstanding Bonds. Any moneys in the Surplus Account not used to call and redeem Bonds or to reimburse the Bank as herein provided shall be used and applied to pay the principal of the Bonds as such principal becomes due and payable, in annual amounts which bear the same ratio to the annual principal due on the Bonds that the amount deposited in the Surplus Account bears to the original face amount of the Bonds (unless in the opinion of Bond Counsel another use would not adversely affect the Tax-exempt status of interest on the Bonds). Notwithstanding Section 5.05, the moneys in the Surplus Account shall be invested at a yield no higher than the yield on the Outstanding Bonds (unless in the opinion of Bond Counsel investment at a higher yield would not adversely affect the Tax-exempt status of interest on the Bonds), and all such investment income shall be deposited in the Surplus Account and expended or reinvested as provided above. (E) The Trustee shall establish, maintain and hold in trust a separate fund designated as the "Costs of Issuance Fund." The moneys in the Costs of Issuance Fund shall be held by the Trustee in trust and applied to the payment of Costs of Issuance, upon a requisition or letter filed with the Trustee by an Authorized Representative of the Borrower or a designee of an Authorized Representative of the Borrower. Any money remaining in the Costs of Issuance Fund on February 1, 1998 shall be either transferred to the Project Fund or returned to the Borrower, at the direction of the Borrower. 24 SECTION 3.04. Validity of Bonds. The validity of the authorization and issuance of the Bonds is not dependent on and shall not be affected in any way by any proceedings taken by the Authority or the Trustee with respect to or in connection with the Agreement. The recital contained in the Bonds that the same are issued pursuant to the Act and the Constitution and laws of the State shall be conclusive evidence of their validity and of compliance with the provisions of law in their issuance. ARTICLE IV REDEMPTION AND PURCHASE OF BONDS SECTION 4.01. Terms of Redemption. The Bonds are subject to redemption by the Authority if and to the extent the Borrower is entitled to make and makes, or is required to make, a payment or prepayment pursuant to Articles IV or VIII of the Agreement. All such prepayments by the Borrower shall be deposited in the Redemption Account. The Authority shall not call the Bonds for optional redemption, and the Trustee shall not give notice of any such redemption, unless the Borrower has so directed in accordance with the Agreement and has made or caused to be made all required installments of the Borrower's obligations under the Agreement; provided that the Authority may require such payment under Section 8.3 of the Agreement without the Borrower's direction. The Bonds shall be subject to redemption by the Authority upon the following terms in increments of $5,000, provided that in the event of redemption of less than all of the Bonds, the amount which remains Outstanding shall be in Authorized Denominations: (1) Sinking Fund Redemption. The Bonds are not subject to sinking fund redemption. (2) Prior to the Fixed Rate Date. On or prior to the Fixed Rate Date, the Bonds are subject to optional redemption on any Interest Payment Date, in whole or in part, to the extent of prepayments of amounts due under the Agreement made at the option of the Borrower pursuant to Section 8.2(b) of the Agreement with the written approval of the Bank, at a redemption price of 100% of the principal amount of the Bonds to be redeemed, plus interest accrued thereon to the redemption date. (3) Taxability. In the event of a prepayment pursuant to Section 8.3(a)(ii) or Section 8.3(a)(iii) of the Agreement as a result of a Determination of Taxability, Bonds Outstanding on the date of the occurrence of such Determination of Taxability shall be redeemed in whole at any time within 60 days after such occurrence, at a redemption price of 100% of the principal amount thereof plus interest accrued thereon to the redemption date. No redemption of Bonds shall be made pursuant to any of the other provisions of this Section 4.01 following a Determination of Taxability. IF THE LIEN OF THIS INDENTURE IS DISCHARGED PRIOR TO THE OCCURRENCE OF A DETERMINATION OF TAXABILITY, THEN THE BONDS SHALL NOT BE REDEEMED AS DESCRIBED IN THIS SUBSECTION 4.01(3). (4) Letter of Credit. The Bonds shall be redeemed in whole, at a redemption price equal to 100% of the principal amount thereof, plus interest accrued thereon to the redemption date, on a redemption date not less than fifteen (15) days preceding the Expiration Date of the Letter of Credit selected by the Trustee if no Alternate Letter of Credit has been delivered to the Trustee in accordance with Section 5.8 of the Agreement. 25 (5) Extraordinary Events. To the extent of a prepayment by the Borrower pursuant to Sections 8.2(a), 8.3(a)(i) or 8.3(b) of the Agreement, the Bonds are subject to redemption prior to their stated maturity as a whole or in part, on any date, at a redemption price equal to 100% of the principal amount thereof, plus interest accrued thereon to the redemption date. (6) Optional Redemption After the Fixed Rate Date. After the Fixed Rate Date, the Bonds are subject to redemption to the extent of prepayments of amounts due under the Agreement made at the option of the Borrower pursuant to Section 8.2(b) of the Agreement, with the consent of the Bank, in whole or in part, on any Interest Payment Date during the applicable periods specified below, at the applicable redemption price stated below, plus interest accrued thereon to the redemption date: Number of Years From Fixed Rate Date First Optional Redemption to Final Maturity Redemption Date Price greater than 9 years 7 years from 102%, conversion declining 1% annually to 100% 6-9 years 6 years from 101%, conversion declining 1% annually to 100% less than 6 years no optional redemption Notwithstanding the optional redemption schedule set forth above, on or prior to the Fixed Rate Date, the Remarketing Agent may provide an alternate optional redemption schedule if it obtains an opinion of Bond Counsel that such alternate schedule will not cause interest on the Bonds not to be Tax-exempt. (7) Mandatory Redemption for Reimbursement Agreement Default. The Bonds shall be redeemed in whole, at a redemption price equal to 100% of the principal amount thereof, plus interest accrued thereon to the redemption date, within five (5) calendar days (and before the following Saturday if the fifth calendar day is a Saturday) from the date the Trustee receives written notice from the Bank that an event of default has taken place under the Reimbursement Agreement and directing the Trustee to redeem the Bonds. (8) Mandatory Redemption from Excess Funds. The Bonds are subject to redemption in part on any Interest Payment Date at a redemption price equal to 100% of the principal amount thereof, plus accrued interest to the redemption date, on the next succeeding Interest Payment Date to the extent of amounts remaining in the Project Fund upon completion of the Project which are deposited in the Surplus Account and directed to be used to redeem Bonds as provided in Section 3.03(D). SECTION 4.02. Selection of Bonds for Redemption. Whenever provision is made in this Indenture for the redemption of less than all of the Bonds, the Trustee shall select the Bonds to be 26 redeemed from all Bonds or such given portion thereof not previously called for redemption by lot in any manner which the Trustee in its sole discretion shall deem appropriate and fair, to be credited against the principal of the Bonds to be redeemed; provided, however, that in connection with an optional redemption of the Bonds, Pledged Bonds shall be the first Bonds selected for redemption; and provided further, that the Bonds Outstanding after giving effect to any redemption shall be in Authorized Denominations. Upon selection of Bonds for redemption on or prior to the Fixed Rate Date, the Trustee will immediately notify the Tender Agent of the Bonds selected for redemption. SECTION 4.03. Notice of Redemption. (A) The Trustee shall mail notice of redemption (1) prior to the Fixed Rate Date, not less than fifteen days before such redemption date, (except in the case of redemptions pursuant to Section 4.01(4) in which case not less than five days or in the case of redemptions pursuant to Section 4.01(7), in which case notice shall be given as soon as practicable), and (2) after the Fixed Rate Date, not less than thirty days before such redemption date (except in the case of redemptions pursuant to Section 4.01(4), in which case not less than five days or in the case of redemptions pursuant to Section 4.01(7), in which case notice shall be given as soon as practicable) to the respective Holders of any Bonds designated for redemption at their addresses on the registration books maintained by the Bond Registrar. Each notice of redemption shall state the redemption date, the place or places of redemption, if less than all of the Bonds are to be redeemed, the distinctive numbers of the Bonds to be redeemed, and in the case of Bonds to be redeemed in part only, the respective portions of the principal amount thereof to be redeemed. Each such notice shall also state that on said date there will become due and payable on each of said Bonds the principal thereof or of said specified portion of the principal thereof in the case of a Bond to be redeemed in part only, and that from and after such redemption date interest thereon shall cease to accrue, and shall require that such Bonds be then surrendered. (B) Notice of redemption of Bonds shall be given by the Trustee, at the expense of the Authority, for and on behalf of the Authority. (C) In the case of redemption pursuant to Section 4.01 in connection with refunding obligations to be issued for such purpose, notice of such redemption may be cancelled if such refunding obligations are not issued on or prior to the date fixed for such redemption. (D) Receipt of such notice shall not be a condition precedent to such redemption and failure so to mail any such notice to a Holder shall not affect the validity of the proceedings for the redemption of Bonds of any Holder. (E) The Trustee shall, at the same time the notice in subsection (A) above is mailed, also send a copy of the notice by certified mail or by overnight delivery to each Securities Depository and to an Information Service. Failure to provide notice to the Tender Agent, the Remarketing Agent, a Securities Depository or to an Information Service shall not affect the validity of proceedings for the redemption of Bonds. SECTION 4.04. Partial Redemption of Bonds. Upon surrender of any Bond redeemed in part only, the Authority shall execute and the Bond Registrar shall authenticate and deliver to the registered owner thereof, at the expense of the Authority, a new Bond or Bonds of Authorized Denominations equal in aggregate principal amount to the unredeemed portion of the Bond surrendered. SECTION 4.05. Effect of Redemption. Notice of redemption having been duly given as aforesaid, and Available Moneys for payment of the redemption price of the Bonds, together with interest accrued to the date fixed for redemption, being held by the Trustee, the Bonds (or portions 27 thereof) so called for redemption shall become due and payable on the redemption date designated in such notice, interest on the Bonds (or portions thereof) so called for redemption shall cease to accrue, said Bonds (or portions thereof) shall cease to be entitled to any benefit or security under this Indenture, and the Holders of said Bonds shall have no rights in respect thereof except to receive payment of said principal, premium, if any, and interest accrued to the date fixed for redemption. All Bonds redeemed pursuant to the provisions of this Article shall be cancelled upon surrender thereof by the Trustee and delivered to or upon the order of the Authority. SECTION 4.06. Purchase of Bonds by Tender Agent. Prior to the Fixed Rate Date, the Bonds may be delivered by the Holders thereof to the Tender Agent at its principal corporate trust office in San Francisco, California, or such other place as the Tender Agent may designate in writing to Bondholders, the Authority, the Trustee, the Bank, the Borrower and the Remarketing Agent. Any Bond so delivered shall be purchased by the Tender Agent on demand of the Holder thereof on the close of any Business Day at a purchase price equal to the principal amount thereof plus accrued interest to but not including the date of purchase (unless such date is an Interest Payment Date, in which case the purchase price will be the principal amount of such Bond); provided that the Tender Agent will be under no obligation to use its own funds to purchase such Bonds and provided further that sufficient funds in the Purchase Fund are immediately available for purchase of the Bonds and upon: (A) delivery to the Tender Agent of an irrevocable written notice by 4:00 p.m., California time, (if not received by 4:00 p.m., California time, on a Business Day it shall be deemed received on the next succeeding Business Day) which states (A) the name and address of the Holder, (B) the number or numbers of the Bond or Bonds to be purchased, (C) the aggregate principal amount of the Bond or Bonds to be purchased, and (D) the date on which the Bond is or Bonds are to be purchased, which date shall be a Business Day not prior to the seventh (7th) calendar day next succeeding the date of delivery of such notice; and (B) delivery to the Tender Agent at or prior to 10:00 a.m., California time, on the Purchase Date specified in the aforesaid notice, of the Bond or Bonds to be tendered; provided, however, that any Bond for which a notice of the exercise of the purchase option has been given as provided in subsection (A) above and which is not so delivered shall be deemed delivered on the date of purchase and shall be purchased in accordance with the Indenture. All Bonds, or portions thereof, purchased pursuant to this Section 4.06 shall be purchased in an amount equal to an Authorized Denomination. The Trustee shall upon request of the Tender Agent calculate the purchase price of any Bonds purchased pursuant to this Section 4.06 and shall notify the Tender Agent of such amount prior to the Purchase Date. SECTION 4.07. Mandatory Tender of Bonds. On each Mandatory Tender Date, the Bonds shall be subject to mandatory tender for purchase on such Mandatory Tender Date at a purchase price equal to the principal amount thereof, plus accrued interest, if any. The Holders of all of the Outstanding Bonds shall be required to tender their Bonds for purchase by the Tender Agent on the Mandatory Tender Date. All Bonds which on the Mandatory Tender Date have not been tendered for purchase ("Non-Tendered Bonds"), shall be deemed purchased by the Tender Agent on the Mandatory Tender Date at a price of the principal amount thereof plus unpaid interest accrued, if any, to such date. Replacement Bonds for the Non-Tendered Bonds may be remarketed and delivered to new Holders as instructed by the Borrower or the Remarketing Agent. The Tender Agent shall hold in trust for the Holders of the Non-Tendered Bonds the purchase price thereof, and after the Mandatory Tender Date such owners will 28 no longer be entitled to any of the benefits of this Indenture except for the payment of such purchase price. ARTICLE V REVENUES; FUNDS AND ACCOUNTS; PAYMENT OF PRINCIPAL AND INTEREST SECTION 5.01. Pledge and Assignment; Revenue Fund. (A) Subject only to the provisions of this Indenture permitting the application thereof for the purposes and on the terms and conditions set forth herein, all of the Revenues and any other amounts (including proceeds of the sale of Bonds) held in any fund or account established pursuant to this Indenture (except to the extent provided in Sections 5.05, 7.03 and 8.06 and excepting the Rebate Fund created by Section 5.07) are hereby pledged by the Authority to secure the payment of the principal and purchase price of and interest on the Bonds in accordance with their terms and the provisions of this Indenture and thereafter, on a basis subordinate thereto, to secure the Borrower's obligations to the Bank under the Reimbursement Agreement. Said pledge shall constitute a lien on and security interest in such assets and shall attach, be perfected and be valid and binding from and after delivery by the Trustee of the Bonds, without any physical delivery thereof or further act. (B) The Authority hereby transfers in trust, and assigns to the Trustee, for the benefit of the Holders of the Bonds, and the Bank, to the extent of its interest therein, all of the Revenues and other assets pledged in subsection (A) of this Section and all of the right, title and interest of the Authority in the Agreement (except for the right to receive any Additional Payments to the extent payable to the Authority, any rights of the Authority to indemnification and rights of inspection and consent). The Trustee shall be entitled to and shall collect and receive all of the Revenues, and any Revenues collected or received by the Authority shall be deemed to be held, and to have been collected or received, by the Authority as the agent of the Trustee and shall forthwith be paid by the Authority to the Trustee. The Trustee also shall be entitled to and shall take all steps, actions and proceedings reasonably necessary in its judgment to enforce, either jointly with the Authority or separately, all of the rights of the Authority and all of the obligations of the Borrower under the Agreement. The Trustee agrees that, so long as the Trustee holds any Revenues or any other amounts (including proceeds of the sale of the Bonds) in any fund or account established pursuant to this Indenture which are pledged by the Authority or the Borrower to secure the payment of the principal of and interest on the Bonds and the Borrower's reimbursement obligations under the Reimbursement Agreement, the Trustee shall hold the same as the collateral agent and bailee of the Bank but only to the extent of amounts paid by the Bank under the Letter of Credit for which the Bank has not received reimbursement from the Borrower for purposes of perfecting the lien and security interest of the Bank therein. Upon receipt of written notice from the Bank that the Borrower has failed to reimburse the Bank for a draw under the Letter of Credit as required by the Reimbursement Agreement, the Trustee shall either cause all accounts and investments which are the subject of the preceding sentence to be titled in such a manner to reflect that the Bank has an interest therein as described in the preceding sentence or ensure that each Person with whom the Trustee places or through whom the Trustee invests any moneys which are the subject of the preceding sentence is advised of the Bank's interest therein as described in the preceding sentence and instructed to mark its records to reflect such interest. The Trustee shall not pledge, hypothecate, transfer or release all or any portion of the Revenues to any persons (including, without limitation, the Borrower) other than Holders of the Bonds in payment thereof or in any manner 29 not in accordance with this Indenture or the Reimbursement Agreement without the written consent of the Authority and the Bank, except as otherwise required by a court of law. (C) All Revenues shall be promptly deposited by the Trustee upon receipt thereof in a special fund designated as the Revenue Fund which the Trustee shall establish, maintain and hold in trust; except as otherwise provided in Section 5.02, all moneys received by the Trustee and required to be deposited in the Project Fund shall be promptly deposited in the Project Fund and all moneys received by the Trustee and required to be deposited in the Redemption Account shall be promptly deposited in the Redemption Account, which the Trustee shall establish, maintain and hold in trust. All Revenues deposited with the Trustee shall be held, disbursed, allocated and applied by the Trustee only as provided in this Indenture. All moneys held by the Tender Agent for the payment of the principal or purchase price of, premium, if any, and interest on the Bonds, shall be held by the Tender Agent in trust for the payment of such Bonds. SECTION 5.02. Allocation of Revenues. Loan Repayments received by the Trustee from the Borrower pursuant to Section 4.2(a) of the Agreement shall be deposited by the Trustee into the following respective accounts (each of which the Trustee shall establish and maintain within the Revenue Fund), in the following amounts, in the following order of priority, and the requirements of each such account (including the making up of any deficiencies in any such account resulting from lack of Revenues sufficient to make any earlier required deposit) at the time of deposit shall be satisfied before any transfer is made to any account subsequent in priority, and provided, that no moneys representing drawings under the Letter of Credit shall be transferred into the Interest Account, the Principal Account or the Redemption Account of the Revenue Fund: First: to the Interest Account, the amount paid by the Borrower and designated as or attributable to interest on the Bonds in the most recent Loan Repayment, so that the aggregate of such amounts will, on the next Interest Payment Date, equal the amount of interest due on the Bonds on such Interest Payment Date. Second: to the Principal Account, the amount paid by the Borrower and designated as or attributable to principal of the Bonds in the most recent Loan Repayment, so that the aggregate of such amounts will, on the next succeeding principal payment date, equal the amount of principal due (whether at maturity or by acceleration) on such principal payment date. Third: to the Redemption Account, the aggregate amount of principal and premium, if any, next coming due by redemption permitted (as directed in writing by the Borrower) or required under Article IV hereof, or any portion thereof paid by the Borrower. SECTION 5.03. Priority of Moneys in Revenue Fund; Letter of Credit Account. (A) Funds for the payment of the principal or redemption price of and interest on the Bonds shall be derived from the following sources in the order of priority indicated in each of the accounts in the Revenue Fund; provided however, that amounts in the respective accounts within the Revenue Fund shall be used to pay the principal or redemption price of and interest on the Bonds held by Holders other than the Bank or the Borrower prior to the payment of the principal and interest on the Bonds held by the Bank or the Borrower, and provided further, that if principal or redemption price (or any portion thereof) of and interest on the Bonds is paid with moneys described in subparagraph (i) of this Section 5.03(A), any other moneys on deposit in the respective accounts in the Revenue Fund shall be applied to immediately reimburse the Bank by wire transfer in the amount of any such drawings: 30 (i) moneys paid into the Letter of Credit Account of the Revenue Fund representing the proceeds of drawings by the Trustee under the Letter of Credit; (ii) moneys paid into the Interest Account, if any, representing accrued interest received at the initial sale of the Bonds and proceeds from the investment thereof which shall be applied to the payment of interest on the Bonds; (iii) moneys paid into the Revenue Fund pursuant to Section 10.01(B) and proceeds from the investment thereof, which constitute Available Moneys; (iv) moneys deposited into the Redemption Account pursuant to Section 3.03(D) and proceeds from the investment thereof; (v) any other moneys (not derived from drawings under the Letter of Credit) paid into the Revenue Fund and proceeds from the investment thereof, which constitute Available Moneys; and (vi) any other moneys paid into the Revenue Fund and proceeds from the investment thereof, which are not Available Moneys. The Trustee shall create within the Revenue Fund a separate account called the "Letter of Credit Account," and all moneys drawn under the Letter of Credit shall be deposited and disbursed either in the Letter of Credit Account or the Liquidity Account established pursuant to Section 8.10. None of the Borrower, any Related Party, the Trustee or the Authority shall have any legal, equitable or beneficial right, title or interest in the Letter of Credit Account or the Liquidity Account. The Letter of Credit Account and the Liquidity Account shall be established and maintained by the Trustee and the Tender Agent, respectively, and held in trust apart from all other moneys and securities held under this Indenture or otherwise, and over which the Trustee and the Tender Agent, respectively, shall have the exclusive and sole right of withdrawal for the exclusive benefit of the Holders of the Bonds with respect to which each drawing is made. (B) The Trustee shall draw moneys under the Letter of Credit in accordance with the terms thereof in amounts necessary to make full and timely payments of principal of, premium, if any, and interest on the Bonds, other than Bonds owned by or for the account of the Borrower or the Bank when due, whether at maturity, redemption, acceleration, an Interest Payment Date or otherwise. In addition, the Trustee shall draw moneys under the Letter of Credit in accordance with the terms thereof to the extent necessary to make full and timely payments required to be made pursuant to, and in accordance with, Article VIII hereof to pay the purchase price of tendered Bonds. The Trustee shall notify the Borrower of any proposed drawing on the Letter of Credit (other than with respect to scheduled payments of principal and interest), as and when it notifies the Bank. (C) If on the Fixed Rate Date there shall have been delivered to the Trustee an Alternate Credit Facility pursuant to Section 5.7 of the Agreement or if at any time there shall have been delivered to the Trustee an Alternate Letter of Credit pursuant to Section 5.8 of the Agreement, then the Trustee shall accept such Alternate Credit Facility or Alternate Letter of Credit, as applicable, and promptly surrender the previously held Letter of Credit to the issuing Bank for cancellation, and shall promptly take all actions requested by the issuing Bank to convey to such Bank or otherwise relinquish all of its right, title and interest in any security held jointly by the issuing Bank and the Trustee. If at any time there shall cease to be any Bonds Outstanding hereunder, the Trustee shall promptly surrender 31 the Letter of Credit to the Bank for cancellation. The Trustee shall comply with the procedures set forth in the Letter of Credit relating to the surrender thereof. SECTION 5.04. Letter of Credit. Subject to the provisions of Section 5.03(C), the Trustee shall hold and maintain the Letter of Credit for the benefit of the Bondholders until the Letter of Credit expires in accordance with its terms. The Trustee shall diligently observe all terms, covenants and conditions of the Letter of Credit, including payment when due of any draws on the Letter of Credit, and the provisions relating to the payment of draws on, and reinstatement of amounts that may be drawn under, the Letter of Credit, and will not consent to, agree to or permit any amendment or modification of the Letter of Credit which would adversely affect the rights or security of the Holders of the Bonds. If at any time during the term of the Letter of Credit, any successor Trustee shall be appointed and qualified under this Indenture, the resigning or removed Trustee shall request that the Bank transfer the Letter of Credit to the successor Trustee in accordance with the procedures for transfer specified in the Letter of Credit. If the resigning or removed Trustee fails to make this request, the successor Trustee shall do so before accepting appointment. The Trustee shall send notice to the Bank and the Borrower of the expiration of the Letter of Credit at least two months prior to the date of such expiration. At least thirty (30) days prior to the Letter of Credit Substitution Date, the Trustee shall send a written notice to the Bondholders relating to the Borrower's election pursuant to Section 5.8 of the Agreement to deliver an Alternate Letter of Credit to the Trustee. Such notice shall (i) specify the proposed Letter of Credit Substitution Date, (ii) require the Holders of all of the Outstanding Bonds to tender their Bonds for purchase on the Mandatory Tender Date pursuant to Section 4.07, and (iii) state that all Outstanding Bonds not purchased on or before the Mandatory Tender Date will be deemed to be purchased on the Mandatory Tender Date at a price equal to the principal amount thereof, plus unpaid interest, if any, accrued to such date. SECTION 5.05. Investment of Moneys. Subject to the following sentence, all moneys in any of the funds or accounts established pursuant to this Indenture shall be invested by the Trustee as directed in writing by an Authorized Representative of the Borrower, in Permitted Investments maturing not later than the date on which it is estimated that such moneys will be required for the purposes specified in this Indenture; provided, however, that: (i) moneys on deposit in the Letter of Credit Account and the Purchase Fund and any moneys held pursuant to Section 4.07 shall be held uninvested; (ii) any moneys held in trust for the payment or redemption of Bonds pursuant to Article X shall be invested as provided in Section 10.03; (iii) moneys held in the Rebate Fund shall be invested in direct obligations of the United States or bonds or other obligations guaranteed by the United States government or for which the full faith and credit of the United States is pledged for the payment of principal and interest thereof, or in money market funds the investment of which is limited to such obligations, in each case rated in the highest rating category applicable to such investments which mature not later than the date on which it is estimated that such moneys will be required; and (iv) moneys described in clause (ii), (iii), or (iv) of Section 5.03(A) shall be invested in Permitted Investments rated A-l or Prime 1 or higher by S&P and Moody's which mature not later than the date on which such moneys will be required to pay the Bonds or the interest thereon. Immediately upon the giving by the Trustee of the notice provided for in paragraph (C) of Section 3.03 of this Indenture, all moneys in any of the funds or accounts established pursuant to this Indenture, subject to the limitations set forth in (i) through (iv) of the first sentence above, shall be invested by the Trustee in Permitted Investments maturing not later than the date on which it is estimated that such moneys will be required for the purposes specified in this Indenture. Permitted Investments may be purchased at such prices as the Trustee may in its discretion determine or as may be directed by the Borrower or its agent. All Permitted Investments shall be acquired as directed by the Borrower subject to the limitations set forth in Section 6.06, the limitations 32 as to maturities in this Section set forth, and such additional limitations or requirements consistent with the foregoing as may be established by Request of the Borrower. Notwithstanding any other provision herein, in the absence of written investment instructions from the Borrower directing the Trustee by noon of the Business Day preceding the day when investments are to be made, the Trustee is directed to invest available funds not described in clauses (i), (ii), or (iii) of the first paragraph of this Section in Investment Securities. The Trustee shall not be liable for any consequences resulting from any investments made pursuant to the preceding sentence except for its own negligence or wilful misconduct. All interest, profits and other income received from the investment of moneys in any fund established pursuant to this Indenture, (1) prior to delivery to the Trustee of the Certificate of the Borrower with respect to completion of the Project (as provided in Section 3.03(D)) shall be deposited when received in the Project Fund, and (2) after the delivery of such Certificate shall be deposited in the Revenue Fund; except that any such interest, profits and other income received from the investment of: (i) any moneys held in trust for the payment or redemption of Bonds pursuant to Article X shall be applied as provided in Article X; and (ii) any moneys held in the Rebate Fund shall be deposited in such fund. Notwithstanding anything to the contrary contained in this paragraph, an amount of interest received with respect to any Permitted Investment equal to the amount of accrued interest, if any, paid as part of the purchase price of such Permitted Investment shall be credited to the fund from which such accrued interest was paid. For the purpose of determining the amount in any fund, all Permitted Investments credited to such fund shall be valued at the market value of such Permitted Investments. The Trustee may act as principal or agent in the making or disposing of any investment. The Trustee may sell at the best price obtainable in the Trustee's sole discretion, or present for redemption, any Permitted Investment so purchased whenever it shall be necessary to provide moneys to meet any required payment, transfer, withdrawal or disbursement from the fund to which such Permitted Investment is credited, and the Trustee shall not be liable or responsible for any loss resulting from such investment except for its own negligence or wilful misconduct. For investment purposes only, the Trustee may commingle moneys held in the Interest Account and Principal Account of the Revenue Fund. SECTION 5.06. Additional Duties of Trustee. While the Bonds bear interest at the Weekly Interest Rate, on or prior to the Business Day preceding each Interest Payment Date, the Trustee shall send to the Borrower an invoice for the interest accrued on the Bonds for the current Interest Period which is to be paid pursuant to Section 4.2 of the Agreement. While the Bonds bear interest at the Fixed Interest Rate, thirty (30) days prior to each Interest Payment Date, the Trustee shall send to the Borrower an invoice for the interest due on the Bonds on the next succeeding Interest Payment Date which is to be paid pursuant to Section 4.2 of the Agreement. The Trustee shall send a copy of any such invoice sent to the Borrower to the Bank. If full payment of any such invoice is not received by the date the Borrower is required to make such payment pursuant to Section 4.2 of the Agreement, the Trustee shall immediately notify in writing the Bank, the Borrower and the Authority of such nonpayment or underpayment by the Borrower. The Trustee shall immediately give the Bank written notice upon the failure of the Borrower to make any principal payment pursuant to Section 4.2 of the Agreement. SECTION 5.07. Establishment of Rebate Fund. (A) The Trustee shall establish and maintain a fund separate from any other fund established and maintained hereunder designated as the "Rebate Fund." There shall be deposited in the Rebate Fund such amounts as are required to be deposited therein pursuant to the written instructions of the Borrower. All money at any time deposited in the Rebate Fund shall be held by the Trustee in trust, to the extent required to satisfy the Rebate 33 Requirement (as defined in the Tax Regulatory Agreement), for payment to the federal government of the United States of America and neither the Authority, the Bondholders, the Trustee, the Tender Agent, or the Bank shall have any rights in or claim to such moneys. All amounts deposited into or on deposit in the Rebate Fund shall be governed by this Section 5.07 and Sections 3.4 and 5.11 of the Agreement and by the Tax Regulatory Agreement (which is incorporated herein by reference). The Trustee shall be deemed conclusively to have complied with said Sections if it follows the written direction of the Borrower, and shall have no liability or responsibility to enforce compliance by the Borrower with the terms of the Tax Regulatory Agreement or said Sections. (B) Upon receipt of the instructions required to be delivered to the Trustee pursuant to the Tax Regulatory Agreement, the Trustee shall remit part or all of the balance in the Rebate Fund to the United States government, as so directed. In addition, if the instructions delivered to the Trustee pursuant to the Tax Regulatory Agreement so direct, the Trustee shall deposit moneys into or transfer moneys out of the Rebate Fund from or into such accounts or funds excluding the Purchase Fund and the Letter of Credit Account, Available Moneys and moneys being aged to become Available Moneys, as the instructions direct. (C) Notwithstanding any provision of this Section 5.07, if the Authority or the Borrower shall provide to the Trustee an opinion of Bond Counsel that any specified action required under this Section is no longer required or that some further or different action is required to maintain the exclusion from gross income for federal income tax purposes of interest with respect to the Bonds, the Trustee and the Authority may conclusively rely on such opinion in complying with the requirements of this Section, and the covenants hereunder shall be deemed to be modified to that extent. ARTICLE VI PARTICULAR COVENANTS SECTION 6.01. Punctual Payment. The Authority shall punctually pay or cause to be paid the principal, premium, if any, and interest to become due in respect of all the Bonds, in strict conformity with the terms of the Bonds and of this Indenture, according to the true intent and meaning thereof, but only out of Revenues and other assets pledged for such payment as provided in this Indenture. SECTION 6.02. Extension of Payment of Bonds. The Authority shall not directly or indirectly extend or assent to the extension of the maturity of any of the Bonds or the time of payment of any claims for interest by the purchase or funding of such Bonds or claims for interest or by any other arrangement and in case the maturity of any of the Bonds or the time of payment of any such claims for interest shall be extended, such Bonds or claims for interest shall not be entitled, in case of any default hereunder, to the benefits of this Indenture, except subject to the prior payment in full of the principal of all of the Bonds then outstanding and of all claims for interest thereon which shall not have been so extended. Nothing in this Section shall be deemed to limit the right of the Authority to issue bonds for the purpose of refunding any Outstanding Bonds, and such issuance shall not be deemed to constitute an extension of maturity of Bonds. SECTION 6.03. Against Encumbrances. The Authority shall not create, or permit the creation of, any pledge, lien, charge or other encumbrance upon the Revenues and other assets pledged or assigned under this Indenture while any of the Bonds are Outstanding, except the pledge and assignment created by this Indenture. Subject to this limitation, the Authority expressly reserves the right 34 to enter into one or more other indentures for any of its corporate purposes, including other programs under the Act, and reserves the right to issue other obligations for such purposes. SECTION 6.04. Power to Issue Bonds and Make Pledge and Assignment. The Authority is duly authorized pursuant to law to issue the Bonds and to enter into this Indenture and to pledge and assign the Revenues and other assets purported to be pledged and assigned, respectively, under this Indenture in the manner and to the extent provided in this Indenture. The Bonds and the provisions of this Indenture are and will be the legal, valid and binding limited obligations of the Authority in accordance with their terms, and the Authority shall at all times, to the extent permitted by law, defend, preserve and protect said pledge and assignment of Revenues and other assets and all the rights of the Bondholders under this Indenture against all claims and demands of all persons whomsoever. SECTION 6.05. Accounting Records and Reports. The Trustee shall keep or cause to be kept proper books of record and account in which complete and correct entries shall be made of all transactions relating to the receipt, investment, disbursement, allocation and application of the Revenues and the proceeds of the Bonds received by the Trustee with respect to all funds and accounts held hereunder. Such records shall specify the account or fund to which each investment (or portion thereof) held by the Trustee is to be allocated and shall set forth, in the case of each Investment Security, (a) its purchase price, (b) identifying information, including par amount, coupon rate, and payment dates, (c) the amount received at maturity or its sale price, as the case may be, (d) the amounts and dates of any payments made with respect thereto, and (e) the dates of acquisition and disposition or maturity. Such records shall be open to inspection by any Holder and the Bank at any reasonable time during regular business hours on reasonable notice. SECTION 6.06. Arbitrage Covenants. The Authority has in the Agreement caused the Borrower to covenant that the Borrower shall not make any use of the proceeds of the Bonds or of any moneys on deposit to the credit of the Project Fund, the Revenue Fund or the Rebate Fund which may be deemed to be proceeds of the Bonds pursuant to Section 148 of the Code and the applicable Treasury Regulations thereunder which would cause any Bond to be an "arbitrage bond" within the meaning of said Section and said regulations and that the Borrower will comply with the requirements of said Section and said regulations, as the same may be amended from time to time, so long as any Bonds remain Outstanding. SECTION 6.07. Other Covenants. (A) The Trustee shall promptly collect all amounts due from the Borrower pursuant to the Agreement, shall perform all duties imposed upon it pursuant to the Agreement and shall diligently enforce, and take all steps, actions and proceedings reasonably necessary for the enforcement of all of the rights of the Authority and all of the obligations of the Borrower. (B) The Authority shall not amend, modify or terminate any of the terms of the Agreement, or consent to any such amendment, modification or termination, without the written consent of the Trustee and the Bank. The Trustee shall give such written consent only if (1) in the opinion of the Trustee, in reliance upon the advice of counsel, such amendment, modification or termination will not materially adversely affect the interests of the Bondholders or result in any material impairment of the security hereby given for the payment of the Bonds, or (2) the Authority first obtains the written consent of the Holders of a majority in principal amount of the Bonds then Outstanding to such amendment, modification or termination, provided that no such amendment, modification or termination shall reduce the amount of Loan Repayments to be made to the Authority or the Trustee by the Borrower pursuant to the Agreement, or extend the time for making such payments, without the written consent 35 of all of the Holders of the Bonds then Outstanding. The Trustee shall be entitled to rely upon an opinion of counsel with respect to the effect of any amendments hereto or to the Agreement. SECTION 6.08. Further Assurances. The Authority shall make, execute and deliver any and all such further indentures, instruments and assurances as may be reasonably necessary or proper to carry out the intention or to facilitate the performance of this Indenture and for the better assuring and confirming unto the Holders of the Bonds of the rights and benefits provided in this Indenture. SECTION 6.09. Covenant to Enter into Agreement or Contract to Provide Ongoing Disclosure. The Borrower has covenanted and agreed with the Authority in Section 5.12 of the Agreement to enter into an agreement or contract, constituting an undertaking (the "Undertaking"), to provide ongoing disclosure for the benefit of the Bondholders as required by Paragraph (b)(5)(i) of the Securities and Exchange Commission Rule 15c2-12 under the Securities Exchange Act of 1934, as amended (17 CFR Part 240 Section 240.15c2-12) (the "Disclosure Requirements"), to the extent the Bonds or the remarketing thereof are at any time not exempt from the Disclosure Requirements. The Undertaking is hereby assigned by the Authority to the Trustee for the benefit of the Bondholders, any Participating Underwriter and any Beneficial Owner. Such assignment is a present absolute assignment and not an assignment of a security interest. Section 5.12 of the Agreement shall be enforceable by any Bondholder, Participating Underwriter or Beneficial Owner. However, neither the Authority nor the Trustee shall have any duty to enforce such Section 5.12. The Authority shall have no liability to the Bondholders, Participating Underwriters, Beneficial Owners or any other person with respect to the actions by the Borrower relating to the Disclosure Requirements. Notwithstanding any other provision of this Indenture, failure of the Borrower to comply with Section 5.12 of the Agreement shall not be considered an Event of Default; provided, however, the Trustee may (and, at the request of any Participating Underwriter or the Holders of at least 25% aggregate principal amount in Outstanding Bonds, shall) or any Beneficial Owner may take such action as may be necessary and appropriate, including seeking mandate or specific performance by court order, to cause the Borrower to comply with its obligations under Section 5.12 of the Agreement. ARTICLE VII EVENTS OF DEFAULT AND REMEDIES OF BONDHOLDERS SECTION 7.01. Events of Default; Acceleration; Waiver of Default. Each of the following events shall constitute an "Event of Default" hereunder: (A) default in the due and punctual payment of the principal of, or premium (if any) on, any Bond when and as the same shall become due and payable, whether at maturity as therein expressed, by proceedings for redemption, by declaration or otherwise; (B) default in the due and punctual payment of any installment of interest on any Bond, when and as such interest installment shall become due and payable and the continuation of such failure for a period of five days after the due date for such payment; (C) failure to pay the purchase price of any Bond tendered in accordance with the provisions of Section 4.06, and the continuation of such failure for a period of five days after such purchase price has become due and payable; (D) failure by the Authority to perform or observe any of the other covenants, agreements or conditions on its part in this Indenture or in the Bonds contained, and the 36 continuation of such failure for a period of sixty (60) days after written notice thereof, specifying such default and requiring the same to be remedied, shall have been given to the Authority, the Bank and the Borrower by the Trustee, or to the Authority, the Bank, the Borrower and the Trustee by the Holders of not less than twenty-five percent (25%) in aggregate principal amount of the Bonds at the time Outstanding; or (E) the occurrence and continuance of a Loan Default Event described in Section 7.1(a), (b) or (c) of the Agreement. No default specified in (D) above shall constitute an Event of Default unless the Authority and the Borrower shall have failed to correct such default within the applicable period; provided, however, that if the default shall be such that it cannot be corrected within such period, it shall not constitute an Event of Default if corrective action is instituted by the Authority or the Borrower within the applicable period and diligently pursued. With regard to any alleged default concerning which notice is given to the Borrower under the provisions of this Section, the Authority hereby grants the Borrower full authority for account of the Authority to perform any covenant or obligation the non-performance of which is alleged in said notice to constitute a default in the name and stead of the Authority with full power to do any and all things and acts to the same extent that the Authority could do and perform any such things and acts and with power of substitution. During the continuance of an Event of Default, unless the principal of all the Bonds shall have already become due and payable, the Trustee may, and upon the written request of the Holders of not less than twenty-five percent (25%) in aggregate principal amount of the Bonds at the time Outstanding, or upon the occurrence of an Event of Default described in (A), (B) or (C) above, the Trustee shall, by notice in writing to the Authority, the Tender Agent, the Remarketing Agent, the Borrower and the Bank, declare the principal of all the Bonds then Outstanding, and the interest accrued thereon, to be due and payable immediately, and upon any such declaration the same shall become and shall be immediately due and payable, anything in this Indenture or in the Bonds contained to the contrary notwithstanding. Upon any such declaration the Trustee shall immediately draw upon any then existing Letter of Credit in accordance with the terms thereof and apply the amount so drawn to pay the principal of and interest on the Bonds so declared to be due and payable. Interest on the Bonds shall cease to accrue upon the declaration of acceleration. The Trustee shall notify the Bondholders of the date of acceleration and the cessation of accrual of interest on the Bonds in the same manner as for a notice of redemption. The preceding paragraph, however, is subject to the condition that if, at any time after the principal of the Bonds shall have been so declared due and payable, and before any judgment or decree for the payment of the moneys due shall have been obtained or entered as hereinafter provided, and before the Letter of Credit has been drawn upon in accordance with its terms and honored, there shall have been deposited with the Trustee a sum sufficient to pay all the principal of the Bonds matured prior to such declaration and all matured installments of interest (if any) upon all the Bonds, with interest on such overdue installments of principal as provided in the Agreement, and the reasonable expenses of the Trustee, and any and all other defaults known to the Trustee (other than in the payment of principal of and interest on the Bonds due and payable solely by reason of such declaration) shall have been made good or cured to the satisfaction of the Trustee or provision deemed by the Trustee to be adequate shall have been made therefor, then, and in every such case, the Holders of at least a majority in aggregate principal amount of the Bonds then Outstanding, by written notice to the Authority and to the Trustee, may, on behalf of the Holders of all the Bonds, rescind and annul such declaration and its consequences and waive such default; but no such rescission and annulment shall extend to or shall affect any subsequent default, or shall impair or exhaust any right or power as a consequence thereof. 37 SECTION 7.02. Institution of Legal Proceedings by Trustee. If one or more Events of Default shall happen and be continuing, the Trustee in its discretion may, and upon the written request of the Holders of a majority in principal amount of the Bonds then Outstanding and upon being indemnified to its satisfaction therefor shall, proceed to protect or enforce its rights or the rights of the holders of Bonds under the Act or under this Indenture or the Agreement by a suit in equity or action at law, either for the specific performance of any covenant or agreement contained herein or therein, or in aid of the execution of any power herein or therein granted, or by mandamus or other appropriate proceeding for the enforcement of any other legal or equitable remedy as the Trustee shall deem most effectual in support of any of its rights or duties hereunder. SECTION 7.03. Application of Revenues and Other Funds After Default. If an Event of Default shall occur and be continuing, all Revenues and any other funds then held or thereafter received by the Trustee under any of the provisions of this Indenture (subject to Sections 5.05, 5.07 and 11.11) shall be applied by the Trustee as follows and in the following order: (1) To the payment of any expenses necessary in the opinion of the Trustee to protect the interests of the Holders of the Bonds and payment of reasonable fees and expenses of the Trustee (including reasonable fees and disbursements of its counsel) incurred in and about the performance of its powers and duties under this Indenture; provided, however, that moneys in the Letter of Credit Account of the Revenue Fund and the Purchase Fund shall not be used for the payment of any such expenses; (2) To the payment of the principal of and interest then due on the Bonds (upon presentation of the Bonds to be paid, and stamping thereon of the payment if only partially paid, or surrender thereof if fully paid) subject to the provisions of this Indenture (including Section 6.02), as follows: (i) Unless the principal of all of the Bonds shall have become or have been declared due and payable, First: To the payment to the persons entitled thereto of all installments of interest then due in the order of the maturity of such installments, and, if the amount available shall not be sufficient to pay in full any installment or installments maturing on the same date, then to the payment thereof ratably, according to the amounts due thereon, to the persons entitled thereto, without any discrimination or preference; and Second: To the payment to the persons entitled thereto of the unpaid principal of any Bonds which shall have become due, whether at maturity or by call for redemption, with interest on the overdue principal at the rate borne by the respective Bonds, and, if the amount available shall not be sufficient to pay in full all the Bonds, together with such interest, then to the payment thereof ratably, according to the amounts of principal due on such date to the persons entitled thereto, without any discrimination or preference. (ii) If the principal of all of the Bonds shall have become or have been declared due and payable, to the payment of the principal and interest then due and unpaid upon the Bonds, with interest on the overdue principal at the rate borne by the Bonds, and, if the amount available shall not be sufficient to pay in full the whole amount so due and unpaid, then to the payment thereof ratably, without preference or priority of principal 38 over interest, or of interest over principal, or of any installment of interest over any other installment of interest, or of any Bond over any other Bond, according to the amounts due respectively for principal and interest, to the persons entitled thereto without any discrimination or preference; provided, however, that neither moneys derived from drawings under the Letter of Credit, Available Moneys, moneys being aged to become Available Moneys, nor the proceeds from remarketing of the Bonds shall be used to pay any of the items listed in clause (1) of this Section, provided, further, that moneys held in the Purchase Fund shall only be used to pay the purchase price of the Bonds. SECTION 7.04. Trustee to Represent Bondholders. The Trustee is hereby irrevocably appointed (and the successive respective Holders of the Bonds, by taking and holding the same, shall be conclusively deemed to have so appointed the Trustee) as trustee and true and lawful attorney-in-fact of the Holders of the Bonds for the purpose of exercising and prosecuting on their behalf such rights and remedies as may be available to such Holders under the provisions of the Bonds, this Indenture, the Agreement, the Act and applicable provisions of any other law. Upon the occurrence and continuance of an Event of Default or other occasion giving rise to a right in the Trustee to represent the Bondholders, the Trustee in its discretion may, and upon the written request of the Holders of not less than twenty-five percent (25%) in aggregate principal amount of the Bonds then Outstanding, and upon being indemnified to its satisfaction therefor (except any actions required to be taken by Section 7.03 hereof, in which event no indemnification shall be required), shall, proceed to protect or enforce its rights or the rights of such Holders by such appropriate action, suit, mandamus or other proceedings as it shall deem most effectual to protect and enforce any such right, at law or in equity, either for the specific performance of any covenant or agreement contained herein, or in aid of the execution of any power herein granted, or for the enforcement of any other appropriate legal or equitable right or remedy vested in the Trustee or in such Holders under this Indenture, the Agreement, the Act or any other law; and upon instituting such proceeding, the Trustee shall be entitled, as a matter of right, to the appointment of a receiver of the Revenues and other assets pledged under this Indenture, pending such proceedings. All rights of action under this Indenture or the Bonds or otherwise may be prosecuted and enforced by the Trustee without the possession of any of the Bonds or the production thereof in any proceeding relating thereto, and any such suit, action or proceeding instituted by the Trustee shall be brought in the name of the Trustee for the benefit and protection of all the Holders of such Bonds, subject to the provisions of this Indenture (including Section 6.02). SECTION 7.05. Bondholders' Direction of Proceedings. Anything in this Indenture to the contrary notwithstanding, the Holders of a majority in aggregate principal amount of the Bonds then Outstanding shall have the right, by an instrument or concurrent instruments in writing executed and delivered to the Trustee, to direct the method of conducting all remedial proceedings taken by the Trustee hereunder, provided that such direction shall not be otherwise than in accordance with law and the provisions of this Indenture, and that the Trustee shall have the right to decline to follow any such direction which in the opinion of the Trustee would be unjustly prejudicial to Bondholders not parties to such direction or for which it has not been provided adequate indemnity to its satisfaction. SECTION 7.06. Limitation on Bondholders' Right to Sue. No Holder of any Bond shall have the right to institute any suit, action or proceeding at law or in equity, for the protection or enforcement of any right or remedy under this Indenture, the Agreement, the Act or any other applicable law with respect to such Bond, unless (1) such Holder shall have given to the Trustee written notice of the occurrence of an Event of Default; (2) the Holders of not less than twenty-five percent (25%) in aggregate principal amount of the Bonds then Outstanding shall have made written request upon the Trustee to exercise the powers hereinbefore granted or to institute such suit, action or proceeding in its 39 own name; (3) such Holder or said Holders shall have tendered to the Trustee reasonable indemnity against the costs, expenses and liabilities to be incurred in compliance with such request; and (4) the Trustee shall have refused or omitted to comply with such request for a period of sixty (60) days after such written request shall have been received by, and said tender of indemnity shall have been made to, the Trustee. Such notification, request, tender of indemnity and refusal or omission are hereby declared, in every case, to be conditions precedent to the exercise by any Holder of Bonds of any remedy hereunder or under law; it being understood and intended that no one or more Holders of Bonds shall have any right in any manner whatever by his or their action to affect, disturb or prejudice the security of this Indenture or the rights of any other Holders of Bonds, or to enforce any right under this Indenture, the Agreement, the Act or other applicable law with respect to the Bonds, except in the manner herein provided, and that all proceedings at law or in equity to enforce any such right shall be instituted, had and maintained in the manner herein provided and for the benefit and protection of all Holders of the Outstanding Bonds, subject to the provisions of this Indenture (including Section 6.02). SECTION 7.07. Absolute Obligation of Authority. Nothing in Section 7.06 or in any other provision of this Indenture, or in the Bonds, contained shall affect or impair the obligation of the Authority, which is absolute and unconditional, to pay the principal of and interest on the Bonds to the respective Holders of the Bonds at their respective dates of maturity, or upon acceleration or call for redemption, as herein provided, but only out of the Revenues and other assets herein pledged therefor, or affect or impair the right of such Holders, which is also absolute and unconditional, to enforce such payment by virtue of the contract embodied in the Bonds. SECTION 7.08. Termination of Proceedings. In case any proceedings taken by the Trustee or any one or more Bondholders on account of any Event of Default shall have been discontinued or abandoned for any reason or shall have been determined adversely to the Trustee or the Bondholders, then in every such case the Authority, the Bank, the Trustee and the Bondholders, subject to any determination in such proceedings, shall be restored to their former positions and rights hereunder, severally and respectively, and all rights, remedies, powers and duties of the Authority, the Bank, the Trustee and the Bondholders shall continue as though no such proceedings had been taken. The Trustee shall deliver copies of all proceedings taken by the Trustee under this Indenture to the Tender Agent. SECTION 7.09. Remedies Not Exclusive. No remedy herein conferred upon or reserved to the Trustee, the Bank or to the Holders of the Bonds is intended to be exclusive of any other remedy or remedies, and each and every such remedy, to the extent permitted by law, shall be cumulative and in addition to any other remedy given hereunder or now or hereafter existing at law or in equity or otherwise. SECTION 7.10. No Waiver of Default. In the event any agreement or covenant contained in this Indenture should be breached by the Authority and thereafter waived by the Trustee or the Holders of the Bonds, such waiver shall be limited to the particular breach so waived and shall not be deemed to waive any other breach hereunder. No delay or omission of the Trustee or of any Holder of the Bonds to exercise any right or power arising upon the occurrence of any default shall impair any such right or power or shall be construed to be a waiver of any such default or an acquiescence therein; and every power and remedy given by this Indenture to the Trustee or to the Holders of the Bonds may be exercised from time to time and as often as may be deemed expedient. SECTION 7.11. Consent To Defaults. Notwithstanding any other provisions of this Article VII, so long as the Letter of Credit is in full force and effect and the Bank has not wrongfully 40 dishonored and is not continuing wrongfully to dishonor drawings under the Letter of Credit and all payments of principal or purchase price and interest on the Bonds have been timely made, no Event of Default shall be declared (except in a case resulting from the failure of the Borrower to pay the Trustee's fees), nor any remedies exercised with respect to any such Events of Default by the Trustee or by the Bondholders and no Event of Default under Section 7.01 shall be waived by the Trustee or the Bondholders to the extent they may otherwise be permitted hereunder, without, in any case, the prior written consent of the Bank. Unless an Alternate Credit Facility has been provided pursuant to Section 5.7 of the Agreement, no Event of Default can be waived, in any circumstance, unless the Letter of Credit has been fully reinstated and is in full force and effect as evidenced in writing by the Bank to the Trustee. ARTICLE VIII THE TRUSTEE, THE REMARKETING AGENT AND THE TENDER AGENT SECTION 8.01. Duties, Immunities and Liabilities of Trustee. (A) The Trustee shall, prior to an Event of Default, and after the curing of all Events of Default which may have occurred, perform such duties and only such duties as are specifically set forth in this Indenture. The Trustee shall, during the existence of any Event of Default (which has not been cured), exercise such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in its exercise, as a prudent person would exercise or use under the circumstances in the conduct of his own affairs. (B) The Trustee may at any time and for any reason be removed by an instrument or concurrent instruments in writing appointing a successor Trustee filed with the Trustee so removed and executed by the Holders of a majority in aggregate principal amount of the Bonds Outstanding. The Trustee may be removed by an instrument in writing, consented to by the Bank which may be executed by the Authority, appointing a successor Trustee filed with the Trustee so removed upon the occurrence of any of the following events: (i) the Trustee shall become incapable of acting; (ii) the Trustee shall be adjudged bankrupt; (iii) the Trustee shall become insolvent; (iv) a receiver is appointed for the Trustee or its property; (v) any public officer shall take control or charge of the Trustee or of the property or affairs for the purposes of rehabilitation, conservation or liquidation; or (vi) the Trustee shall cease to be eligible in accordance with Subsection (E) of this Section; provided that the Authority may not remove the Trustee during the occurrence and continuance of an Event of Default. Notwithstanding the foregoing, the Trustee may not be removed until a successor Trustee has been appointed and has assumed the duties and responsibilities of successor Trustee under this Indenture. (C) The Trustee may at any time resign by giving written notice of such resignation to the Authority and the Bank and by giving the Bondholders notice of such resignation by mail at the addresses shown on the registration books maintained by the Bond Registrar. Upon receiving such notice of resignation, the Authority shall promptly appoint, with the consent of the Bank, a successor Trustee by an instrument in writing. The Trustee shall not be relieved of its duties until such successor Trustee has accepted its appointment. (D) Any removal or resignation of the Trustee and appointment of a successor Trustee shall become effective only upon acceptance of appointment by the successor Trustee. If no successor Trustee shall have been appointed and have accepted appointment within forty-five (45) days of giving notice of removal or notice of resignation as aforesaid, the resigning Trustee or any Bondholder (on behalf of himself and all other Bondholders) may petition any court of competent jurisdiction for the 41 appointment of a successor Trustee, and such court may thereupon, after such notice (if any) as it may deem proper, appoint such successor Trustee. Any successor Trustee appointed under this Indenture, shall signify its acceptance of such appointment by executing and delivering to the Authority and to its predecessor Trustee a written acceptance thereof and a written instrument by the successor Trustee indemnifying the predecessor Trustee for all costs or claims arising after the acceptance of appointment hereunder relating to such successor Trustee's performance of its duties under this Indenture, and thereupon and after the payment by the Authority of all unpaid fees and expenses (including legal fees and expenses) of the predecessor Trustee such successor Trustee, without any further act, deed or conveyance, shall become vested with all the moneys, estates, properties, rights, powers, trusts, duties and obligations of such predecessor Trustee, with like effect as if originally named Trustee herein; but, nevertheless at the Request of the Authority or the request of the successor Trustee, such predecessor Trustee shall execute and deliver any and all instruments of conveyance or further assurance and do such other things as may reasonably be required for more fully and certainly vesting in and confirming to such successor Trustee all the right, title and interest of such predecessor Trustee in and to any property held by it under this Indenture and shall pay over, transfer, assign and deliver to the successor Trustee any money or other property subject to the trusts and conditions herein set forth. Upon request of the successor Trustee, the Authority shall execute and deliver any and all instruments as may be reasonably required for more fully and certainly vesting in and confirming to such successor Trustee all such moneys, estates, properties, rights, powers, trusts, duties and obligations. Upon acceptance of appointment by a successor Trustee as provided in this subsection, the Authority shall mail a notice of the succession of such Trustee to the trusts hereunder to each rating agency which is then rating the Bonds, to the Bondholders at the addresses shown on the registration books maintained by the Bond Registrar, and to the Bank. If the Authority fails to mail such notice within fifteen (15) days after acceptance of appointment by the successor Trustee, the successor Trustee shall cause such notice to be mailed at the expense of the Authority. (E) Any Trustee appointed under the provisions of this Section in succession to the Trustee shall be a trust company or bank having the powers of a trust company, having a combined capital and surplus of at least fifty million dollars ($50,000,000), and subject to supervision or examination by federal or state authority. If such bank or trust company publishes a report of condition at least annually, pursuant to law or to the requirements of any supervising or examining authority above referred to, then for the purpose of this subsection the combined capital and surplus of such bank or trust company shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. In case at any time the Trustee shall cease to be eligible in accordance with the provisions of this subsection (E), the Trustee shall resign immediately in the manner and with the effect specified in this Section. SECTION 8.02. Merger or Consolidation. Any company into which the Trustee may be merged or converted or with which it may be consolidated or any company resulting from any merger, conversion or consolidation to which it shall be a party or any company to which the Trustee may sell or transfer all or substantially all of its corporate trust business, provided such company shall be eligible under subsection (E) of Section 8.01 shall be the successor to such Trustee without the execution or filing of any paper or any further act, anything herein to the contrary notwithstanding. SECTION 8.03. Liability of Trustee. (A) The recitals of facts herein and in the Bonds contained shall be taken as statements of the Authority, and the Trustee shall assume no responsibility for the correctness of the same, or make any representations as to the validity or sufficiency of this Indenture or of the Bonds. In addition, the Trustee shall assume no responsibility with respect to this Indenture or Bonds other than in connection with the duties or obligations assigned to or imposed upon the Trustee herein or in the Bonds. The Trustee shall, however, be responsible for its representations 42 contained in its certificate of authentication on the Bonds. The Trustee shall not be liable in connection with the performance of its duties hereunder, except for its own negligence or willful misconduct. The Trustee may become the owner of Bonds with the same rights it would have if it were not Trustee and, to the extent permitted by law, may act as depositary for and permit any of its officers or directors to act as a member of, or in any other capacity with respect to, any committee formed to protect the rights of Bondholders, whether or not such committee shall represent the Holders of a majority in principal amount of the Bonds then Outstanding. The Trustee may execute any of the trusts or powers set forth herein and perform the duties required of it hereunder by or through attorneys, agents, or receivers, and shall be entitled to the advice of counsel concerning all matters of trusts and its duties herein, and the Trustee shall not be answerable for the default or misconduct of any such attorney, agent or receiver selected by it with reasonable care.

(C) The Trustee shall not be liable with respect to any action taken or omitted to be taken by it in good faith in accordance with the direction of the Holders of not less than a majority in aggregate principal amount of the Bonds at the time Outstanding relating to the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred upon the Trustee under this Indenture. (D) The Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request, order or direction of any of the Bondholders pursuant to the provisions of this Indenture unless such Bondholders shall have offered to the Trustee satisfactory security or indemnity against the costs, expenses and liabilities which may be incurred therein or thereby. (E) The Trustee shall not be liable for any action taken by it in good faith and believed by it to be authorized or within the discretion or rights or powers conferred upon it by this Indenture except for its own negligence or wilful misconduct. (F) The Trustee shall not be deemed to have knowledge of any default or Event of Default hereunder unless and until it shall have actual knowledge thereof, or shall have received written notice thereof, at its principal corporate trust office. Except as otherwise expressly provided herein, the Trustee shall not be bound to ascertain or inquire as to the performance or observance of any of the terms, conditions, covenants or agreements herein or of any of the documents executed in connection with the Bonds, or as to the existence of a default or Event of Default thereunder. The Trustee shall not be responsible for the validity or effectiveness of any collateral given to or held by it. (G) No provision of this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder, or in the exercise of its rights or powers. The Trustee shall, however, in any case make drawings under the Letter of Credit, pay principal of or interest on the Bonds as it becomes due, and accelerate the Bonds as required by this Indenture, notwithstanding anything to the contrary herein. SECTION 8.04. Right of Trustee to Rely on Documents. The Trustee shall be protected in acting upon any notice, resolution, request, consent, order, certificate, report, opinion, bond or other paper or document believed by it to be genuine and to have been signed or presented by the 43 proper party or parties. The Trustee may consult with counsel, who may be counsel of or to the Authority, with regard to legal questions, and the opinion of such counsel shall be full and complete authorization and protection in respect of any action taken or suffered by it hereunder in good faith and in accordance therewith. The Trustee shall not be bound to recognize any person as the Holder of a Bond unless and until such Bond is submitted for inspection, if required, and his title thereto is satisfactorily established, if disputed. Whenever in the administration of the trusts imposed upon it by this Indenture the Trustee shall deem it necessary or desirable that a matter be proved or established prior to taking or suffering any action hereunder, such matter (unless other evidence in respect thereof be herein specifically prescribed) may be deemed to be conclusively proved and established by a Certificate of the Authority, and such Certificate shall be full warrant to the Trustee for any action taken or suffered in good faith under the provisions of this Indenture in reliance upon such Certificate, but in its discretion the Trustee may, in lieu thereof, accept other evidence of such matter or may require such additional evidence as it may deem reasonable. SECTION 8.05. Preservation and Inspection of Documents. All documents received by the Trustee under the provisions of this Indenture shall be retained in its possession and shall be subject at all reasonable times to the inspection of the Authority and any Bondholder, and their agents and representatives duly authorized in writing, at reasonable hours and under reasonable conditions.

(A) The Tender Agent shall immediately provide the Remarketing Agent, the Bank and the Trustee with telephonic notice, promptly confirmed by written notice by 12:00 noon, California time, on the next succeeding Business Day, of the receipt by the Tender Agent of a tender notice from any Bondholder pursuant to Section 4.06 or the receipt by the Tender Agent of a notice from the Borrower of its election to substitute an Alternate Letter of Credit for the then existing Letter of Credit pursuant to Section 5.8 of the Agreement and providing the Remarketing Agent, the Bank and the Trustee with the information contained in such notices. Upon receipt of such telephonic notice, the Remarketing Agent shall offer for sale and use its best efforts to sell the Bonds described in such notice, any such sale to be made at a price equal to the principal amount thereof plus accrued interest. (B) The Remarketing Agent shall (i) by 4:00 p.m., California time, on the Business Day prior to the Purchase Date, give telegraphic or telephonic notice, promptly confirmed by a written notice, to the Trustee, the Tender Agent, the Borrower and the Bank (A) directing the Tender Agent to make available for pick up by 11:00 a.m., California time, on the Purchase Date, at the principal corporate trust office of the Tender Agent (or at such other office as the Tender Agent shall designate) any Bonds for which the Remarketing Agent has arranged sales pursuant to this Section 8.09 and (B) stating the principal amount of Bonds sold pursuant to subsection (A) of this Section 8.09, and (ii) deliver or cause to be delivered to the Tender Agent at or prior to 8:00 a.m., California time, on the Purchase Date the principal of and interest accrued to such Purchase Date on the Bond or Bonds to be so purchased that have been remarketed by the Remarketing Agent, in immediately available funds. Upon receipt of amounts for the purchase of Bonds from the Remarketing Agent, the Tender Agent shall immediately give telephonic notice to the Trustee, the Borrower and the Bank, promptly confirmed in writing of (i) the proceeds received from the Remarketing Agent to be applied to the purchase of the Bonds tendered for purchase, and (ii) the amount that must be drawn under the Letter of Credit for Bonds which have been tendered as to which the Tender Agent has not received the principal of and interest accrued thereon to the Purchase Date from the Remarketing Agent. None of the moneys so provided to the Tender Agent for purchase of Bonds may be derived directly or indirectly from the Borrower, any Related Party or the Authority and therefore the Bonds may not be remarketed to any such entity or person. The notice by the Remarketing Agent shall specify the names, addresses, and taxpayer identification numbers of the purchasers of, and the principal amount and denominations of, such Bonds, if any, for which it has found purchasers as of such date and the principal amount of such Bonds, if any, for which it has not found purchasers as of such date. The Tender Agent shall make available for pick up new Bonds properly executed, registered in the name(s) and issued in Authorized Denominations as may be specified in the notice by the Remarketing Agent to the Tender Agent by 11:00 a.m., California time, on the Purchase Date.

Under no circumstances shall the Tender Agent be obligated to expend any of its own funds in connection with this Indenture. (C) On the date Bonds are to be purchased pursuant to Section 8.10, the Trustee shall, prior to 8:30 a.m., California time, draw on the Letter of Credit in accordance with the provisions thereof to the extent of the purchase price of the Bonds for which the Tender Agent has not received proceeds from the remarketing of such Bonds as evidenced by the notice from the Tender Agent to the Trustee and shall immediately transfer or direct the proceeds of such draw to the Tender Agent to pay the purchase price of such Bonds on the Purchase Date; provided however, that no drawings shall be made under the Letter of Credit to purchase Bonds held by or for the account of the Borrower or the Bank. SECTION 8.10. Creation of Purchase Fund; Purchase of Bonds Delivered to Tender Agent. (A) There is hereby created and established with the Tender Agent, in a trust capacity, a separate fund to be designated as the "Purchase Fund" and there shall be created within the Purchase Fund (i) a separate account called the "Remarketing Account" into which all moneys representing the proceeds of remarketing pursuant to Section 8.09 (which moneys shall be in a form immediately available on the Purchase Date) shall be deposited and (ii) a separate account called the "Liquidity Account" into which the proceeds of drawings by the Trustee under the Letter of Credit shall be deposited. None of the Borrower, any Related Party, the Trustee nor the Authority shall have any legal, equitable or beneficial right, title or interest in the moneys held by the Remarketing Agent or by the Tender Agent in the Purchase Fund, or the Remarketing Account or Liquidity Account therein. The Purchase Fund and each such Account shall be established and maintained by the Tender Agent and held in trust apart from all other moneys and securities held under this Indenture or otherwise, and over which the Tender Agent shall have the exclusive and sole right of withdrawal for the exclusive benefit of the persons tendering or purchasing Bonds with respect to which amounts were deposited into the Purchase Fund and the Accounts created therein. On each day on which Bonds have been tendered for purchase or are deemed to have been tendered for purchase pursuant to this Indenture, after paying or making provision for the payment of the purchase price of such Bonds as in this Indenture provided, the Tender Agent shall promptly remit to the Bank any moneys, but not exceeding the amount drawn on the Letter of Credit for such purchase, on deposit in the Liquidity Account not used to purchase Bonds. (B) Funds for the purchase of Bonds at the principal amount thereof plus unpaid interest accrued to the Purchase Date, if any, shall be paid out of the Purchase Fund in the order of priority indicated: (i) from the Remarketing Account, proceeds from the remarketing of Bonds pursuant to Section 8.09 hereof; and (ii) from the Liquidity Account, moneys representing proceeds of a drawing by the Trustee under the Letter of Credit. (C) In the event that Bonds are not purchased pursuant to this Section, the Trustee shall pay the principal amount of Bonds tendered pursuant to Section 4.06 or Bonds subject to mandatory tender pursuant to Section 4.07 with moneys on deposit in the Revenue Fund pursuant to Section 5.02 hereof and cancel such Bonds. 46 (D) The Tender Agent shall: (i) hold all Bonds delivered to it pursuant to Sections 4.06, 4.07 or 8.11 in trust solely for the benefit of the respective Holders which shall have so delivered such Bonds until moneys representing the purchase price for such Bonds shall have been delivered to or for the account of or to the order of such Holders; and (ii) hold all moneys delivered to it under this Section 8.10 for the purchase of Bonds in trust solely for the benefit of the person or entity which shall have so delivered such moneys until the Bonds purchased with such moneys shall have been delivered to or for the account of such person or entity; (iii) only make such payments called for under this Indenture from immediately available funds transferred to the Tender Agent for payment pursuant to this Indenture which funds are on deposit in an appropriate account maintained by the Tender Agent; (iv) under no circumstances be obligated to expend any of its own funds in connection with this Indenture; (v) in acting with regard to the purchase of Bonds under this Indenture be acting as a conduit and shall not be purchasing Bonds for its own account, and in the absence of written notice from the Authority or the Trustee, shall be entitled to assume that any Bond tendered to it, or deemed tendered to it for purchase, is entitled under this Indenture to be so purchased; and (vi) notify the Remarketing Agent by telephone, telegram or other form of electronic communication of the contents of, and promptly deliver to the Borrower, the Trustee, the Remarketing Agent and the Bank a copy of, each notice delivered to it in accordance with Section 4.06 and, immediately upon the delivery to it of Bonds in accordance with said Section 4.06, give telegraphic or telephonic notice to the Borrower, the Trustee and the Bank specifying the principal amount of the Bonds so delivered.

(B) (i) Bonds paid with the moneys described in subsection (C) of Section 8.10 shall be cancelled. (ii) Bonds paid by the Tender Agent with moneys described in subsection (B)(ii) of Section 8.10 shall be held by the Tender Agent as Pledged Bonds pursuant to the Pledge and Security Agreement for the account of the Borrower in which Bank shall have a security interest. (C) Bonds which have been delivered to the Tender Agent and which thereafter have been sold shall be delivered to such new owners as the Remarketing Agent or the Bank may designate to the Tender Agent, but only upon (i) written confirmation to the Trustee by the Bank that the stated amount of the Letter of Credit has been reinstated with respect to the principal of the Bonds being so re-registered and delivered, together with the portion of the 47 Letter of Credit used to pay accrued interest for the purchase of such Bonds and (ii) written confirmation to the Tender Agent by the Trustee that the stated amount of the Letter of Credit has been reinstated with respect to the principal of the Bonds being so re-registered and delivered, together with the portion of the Letter of Credit used to pay accrued interest for the purchase of such Bonds. The Authority shall cooperate with the Trustee, the Tender Agent, and the Borrower to cause the necessary arrangements to be made and to be thereafter continued whereby funds from the sources specified herein will be made available for the purchase of Bonds presented at the principal office of the Tender Agent and whereby Bonds executed by the Authority and authenticated by the Tender Agent, shall be made available to the extent necessary for delivery pursuant to this Section 8.11.

Anything in this Indenture to the contrary notwithstanding, there shall be no purchases or sales of Bonds pursuant to this Article VIII if there shall have occurred and be continuing an Event of Default described in clauses (A)-(C) of Section 7.01. Anything in this Indenture to the contrary notwithstanding, there shall be no remarketing of Bonds pursuant to this Article VIII if there shall have occurred and be continuing any Event of Default described in Section 7.01 or if any event shall have occurred which with notice or the lapse of time would constitute such an Event of Default. SECTION 8.14. Qualifications of Tender Agent. The Tender Agent shall be a bank or trust company or another institution which has a rating on its long-term debt from Moody's of at least "Baa3" and a short term rating of at least "P-3" authorized to perform all duties imposed upon it by this Indenture and the Remarketing Agreement.

With the consent of the Bank, the Tender Agent may be removed at any time by the Authority, by an instrument, signed by the Authority, filed with the Tender Agent, the Remarketing Agent and the Trustee. The initial Tender Agent appointed under this Indenture is First Trust of California, National Association. The Authority, with the consent of the Bank, shall appoint a successor Tender Agent.

(A) This Indenture and the rights and obligations of the Authority and of the Holders of the Bonds and of the Trustee may be modified or amended from time to time and at any time by an indenture or indentures supplemental thereto, which the Authority and the Trustee may enter into when the written consent of the Holders of a majority in aggregate principal amount of all Bonds then Outstanding, the Borrower and the Bank shall have been filed with the Trustee. No such modification or amendment shall (1) extend the fixed maturity of any Bond, or reduce the amount of principal thereof, or extend the time of payment, or change the method of computing the rate of interest thereon, or extend the time of payment of interest thereon, without the consent of the Holder of each Bond so affected, or (2) reduce the aforesaid percentage of Bonds the consent of the Holders of which is required to effect any such modification or amendment, or permit the creation of any lien on the Revenues and other assets pledged under this Indenture prior to or on a parity with the lien created by this Indenture, or deprive the Holders of the Bonds of the lien created by this Indenture on such Revenues and other assets (except as expressly provided in this Indenture), without the consent of the Holders of all of the Bonds then Outstanding, or (3) adversely affect the interests of the Tender Agent without its prior written consent. It shall not be necessary for the consent of the Bondholders to approve the particular form of any Supplemental Indenture, but it shall be sufficient if such consent shall approve the substance thereof. Promptly after the execution by the Authority and the Trustee of any Supplemental Indenture pursuant to this subsection (A), the Trustee shall mail a copy of the Supplemental Indenture to the Tender Agent and mail a notice, setting forth in general terms the substance of such Supplemental Indenture, to each rating agency then rating the Bonds and the Holders of the Bonds at the address shown on the registration books of the Trustee. Any failure to give such notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such Supplemental Indenture. (B) This Indenture and the rights and obligations of the Authority, of the Trustee and of the Holders of the Bonds may also be modified or amended from time to time and at any time by an indenture or indentures supplemental hereto, which the Authority and the Trustee may enter into without the consent of any Bondholders but with the written consent of the Borrower and the Bank, but only to the extent permitted by law including, without limitation, for any one or more of the following purposes: (1) to add to the covenants and agreements of the Authority contained in this Indenture other covenants and agreements thereafter to be observed, to pledge or assign additional security for the Bonds, or to surrender any right or power herein reserved to or conferred upon the Authority; (2) to make such provisions for the purpose of curing any ambiguity, inconsistency or omission, or of curing or correcting any defective provision, contained in this Indenture, or in regard to matters or questions arising under this Indenture, as the Authority may deem necessary or desirable which do not adversely affect the rights of the Bondholders hereunder; 49 (3) to modify, amend or supplement this Indenture in such manner as to permit the qualification hereof under the Trust Indenture Act of 1939, as amended, or any similar federal statute hereafter in effect, and to add such other terms, conditions and provisions as may be permitted by said act or similar federal statute; (4) to make such provisions for the purpose of conforming to the terms and provisions of any Alternate Letter of Credit or Alternate Credit Facility or to obtain a rating on the Bonds which do not adversely affect the rights of the Bondholders hereunder; and (5) to modify, amend or supplement this Indenture in any other respect which does not adversely affect the rights of the Bondholders hereunder. The Trustee shall give notice of any such modification or amendment to each rating agency then rating the Bonds. (C) The Trustee may in its discretion, but shall not be obligated to, enter into any such Supplemental Indenture authorized by subsections (A) or (B) of this Section which materially adversely affects the Trustee's own rights, duties or immunities under this Indenture or otherwise. SECTION 9.02. Effect of Supplemental Indenture. Upon the execution of any Supplemental Indenture pursuant to this Article, this Indenture shall be deemed to be modified and amended in accordance therewith, and the respective rights, duties and obligations under this Indenture of the Authority, the Trustee and all Holders of Bonds Outstanding shall thereafter be determined, exercised and enforced hereunder subject in all respects to such modification and amendment, and all the terms and conditions of any such Supplemental Indenture shall be deemed to be part of the terms and conditions of this Indenture for any and all purposes. SECTION 9.03. Endorsement of Bonds; Preparation of New Bonds. Bonds delivered after the execution of any Supplemental Indenture pursuant to this Article may, and if the Authority so determines shall, bear a notation by endorsement or otherwise in form approved by the Authority as to any modification or amendment provided for in such Supplemental Indenture, and, in that case, upon demand of the Holder of any Bond Outstanding at the time of such execution and presentation of his Bond for the purpose at the office of the Bond Registrar or at such additional offices as the Bond Registrar may select and designate for that purpose, a suitable notation shall be made on such Bond. If the Supplemental Indenture shall so provide, new Bonds so modified as to conform, in the opinion of the Authority, to any modification or amendment contained in such Supplemental Indenture, shall be prepared and executed by the Authority and authenticated by the Bond Registrar, and upon demand of the Holders of any Bonds then Outstanding shall be exchanged at the principal office of the Bond Registrar, without cost to any Bondholder, for Bonds then Outstanding, upon surrender for cancellation of such Bonds, in equal aggregate principal amounts of the same Series and maturity. SECTION 9.04. Amendment of Particular Bonds.

Any request, consent or other instrument required or permitted by this Indenture to be signed and executed by Bondholders may be in any number of concurrent instruments of substantially similar tenor and shall be signed or executed by such Bondholders in person or by an agent or agents duly appointed in writing. Proof of the execution of any such request, consent or other instrument or of a writing appointing any such agent, or of the holding by any person of Bonds transferable by delivery, shall be sufficient for any purpose of this Indenture and shall be conclusive in favor of the Trustee and of the Authority if made in the manner provided in this Section. The fact and date of the execution by any person of any such request, consent or other instrument or writing may be proved by the certificate of any notary public or other officer of any jurisdiction, authorized by the laws thereof to take acknowledgments of deeds, certifying that the person 55 signing such request, consent or other instrument acknowledged to such notary public or other officer the execution thereof, or by an affidavit of a witness of such execution duly sworn to before such notary public or other officer. The ownership of registered Bonds shall be proved by the bond registration books held by the Bond Registrar. Any request, consent, or other instrument or writing of the Holder of any Bond shall bind every future Holder of the same Bond and the Holder of every Bond issued in exchange therefor or in lieu thereof, in respect of anything done or suffered to be done by the Trustee or the Authority in accordance therewith or reliance thereon. SECTION 11.10. Disqualified Bonds. In determining whether the Holders of the requisite aggregate principal amount of Bonds have concurred in any demand, request, direction, consent or waiver under this Indenture, Bonds which are owned or held by or for the account of the Authority or the Borrower, or by any other obligor on the Bonds, or by any person directly or indirectly controlling or controlled by, or under direct or indirect common control with, the Authority or the Borrower or any other obligor on the Bonds, shall be disregarded and deemed not to be Outstanding for the purpose of any such determination. Bonds so owned which have been pledged in good faith may be regarded as Outstanding for the purposes of this Section if the pledgee shall establish to the satisfaction of the Trustee the pledgee's right to vote such Bonds and that the pledgee is not a person directly or indirectly controlling or controlled by, or under direct or indirect common control with, the Authority or the Borrower or any other obligor on the Bonds. In case of a dispute as to such right, any decision by the Trustee taken upon the advice of counsel shall be full protection to the Trustee. SECTION 11.11. Money Held for Particular Bonds. (A) The money held by the Trustee for the payment of the interest, principal, or premium due on any date with respect to particular Bonds (or portions of Bonds in the case of Bonds redeemed in part only) shall, on and after such date and pending such payment, be set aside on its books and held in trust by it for the Holders of the Bonds entitled thereto, (subject, however, to the provisions of Section 10.04) for a period of two years but without any liability for interest thereon. (B) Upon the expiration of the period specified in subsection (A) above, except as provided in subsection (C) below, funds held by the Trustee pursuant to this Indenture shall be paid, subject to any prior payments pursuant to the provisions of Section 10.04, to the Borrower, and funds held by the Tender Agent shall be paid to the Trustee and thereafter paid, subject to the provisions of Section 10.04, to the Borrower, upon direction of an Authorized Representative of the Borrower, and thereafter Bondholders shall be entitled to look only to the Borrower for payment, and then only to the extent of the amount so deposited with the Borrower, and all liability of the Authority or the Trustee with respect to such money shall thereupon cease, and the Borrower shall not be liable for any interest thereon and shall not be regarded as a trustee of such money. (C) Any moneys held by the Trustee or the Tender Agent, as the case may be, in the Letter of Credit Account or the Liquidity Account for the payment of the principal, premium, or purchase price of any Bonds not so applied to the payment of the Bonds within two years after the date on which the same shall have become due shall be transferred to the Bank. Upon the expiration of the period specified in subsection (A) above, any moneys held by the Tender Agent representing the proceeds of the remarketing of the Bonds but which were not so applied to the payment of Bonds shall be transferred to the Bank. All such moneys shall be subject to escheat to the State in accordance with the laws thereof. 56 Bondholders shall be entitled to look only to the Bank for payment from such moneys, and all liability of the Authority, the Trustee or the Tender Agent with respect to such money shall thereupon cease, and the Trustee, the Tender Agent, the Authority, the Bank, or the Borrower shall not be liable for any interest thereon and such parties shall not be regarded as a trustee of such money. SECTION 11.12. Funds and Accounts. Any fund or account required by this Indenture to be established and maintained by the Trustee may be established and maintained in the accounting records of the Trustee, either as a fund or an account, and may, for the purposes of such records, any audits thereof and any reports or statements with respect thereto, be treated either as a fund or as an account; but all such records with respect to all such funds and accounts shall at all times be maintained in accordance with generally accepted corporate trust industry standards, to the extent practicable, and with due regard for the requirements of Section 6.05 and for the protection of the security of the Bonds and the rights of every Holder thereof and the Bank's interest created herein. SECTION 11.13. Waiver of Personal Liability. No member, officer, agent or employee of the Authority shall be individually or personally liable for the payment of the principal of or premium or interest on the Bonds or be subject to any personal liability or accountability by reason of the issuance thereof; but nothing herein contained shall relieve any such member, officer, agent or employee from the performance of any official duty provided by law or by this Indenture. SECTION 11.14. Execution in Several Counterparts. This Indenture may be executed in any number of counterparts and each of such counterparts shall for all purposes be deemed to be an original; and all such counterparts, or as many of them as the Authority and the Trustee shall preserve undestroyed, shall together constitute but one and the same instrument. SECTION 11.15. Actions Due on Saturdays, Sundays and Holidays. If any date on which a payment, notice or other action required by this Indenture falls on other than a Business Day, then that action or payment need not be taken or made on such date, but may be taken or made on the next succeeding Business Day with the same force and effect as if made on such date. SECTION 11.16. References to Bank. Notwithstanding any provisions contained herein to the contrary, the Bank shall be entitled to take all actions and exercise all rights hereunder for its own account so long as the Bank has not wrongfully dishonored any drawings under the Letter of Credit and the Bank is not in liquidation, bankruptcy or receivership proceedings. After the expiration or termination of the Letter of Credit and after all obligations owed to the Bank pursuant to the Reimbursement Agreement have been paid in full or discharged, all references to the Bank contained herein (other than in Section 10.04) shall be null and void and of no further force and effect.

PROJECT) MATURITY DATE ORIGINAL ISSUE DATE CUSIP August 1, 2027 August 5, 1997 13066P AM0 Registered Owner: CEDE & CO. Principal Sum: EIGHT MILLION FIVE HUNDRED THOUSAND DOLLARS The CALIFORNIA ECONOMIC DEVELOPMENT FINANCING AUTHORITY (the "Authority"), a body public and corporate, and a public instrumentality of the State of California (the "State"), duly organized and existing under the laws of the State, particularly Part 10.2 of Division 3 of Title 2 of the California Government Code (commencing with Section 15710 of the California Government Code), as amended (the "Act"), for value received, hereby promises to pay to the registered owner specified above, or registered assigns, on the maturity date set forth above (subject to any right of prior redemption hereinafter mentioned), the principal sum set forth above, in lawful money of the United States of America, and to pay interest thereon in like lawful money from and including the Interest Payment Date (as defined herein) next preceding the date of registration of this Bond (unless this Bond is registered after a Record Date (as hereinafter defined) and on or before the next succeeding Interest Payment Date or on an Interest Payment Date, in which event it shall bear interest from and including A-1 such Interest Payment Date, or unless this Bond is registered on or prior to September 1, 1997, in which event it shall bear interest from and including the date of initial issuance and delivery (the "Date of Delivery")), until payment of such principal sum shall be discharged as provided in the Indenture (as hereinafter defined), at the rates per annum determined as set forth below. The interest on this Bond will be payable on September 2, 1997, and thereafter on the first Business Day of each month on or prior to the date on which this Bond is converted to bear a fixed rate of interest as provided in the Indenture (the "Fixed Rate Date"), and thereafter on August 1 and February 1 in each year (each such date being referred to herein as an "Interest Payment Date"). The principal (or redemption price) hereof is payable upon presentation hereof at the principal corporate trust office of First Trust of California, National Association (together with any successor as trustee under the Indenture, the "Trustee"), in San Francisco, California, or at such other office as the Trustee may designate. Interest hereon is payable by check or draft mailed, except as provided in the Indenture, to the person whose name appears on the bond registration books of the Trustee as the registered owner hereof as of the close of business on the Record Date, in each case, at such person's address as it appears on such registration books. The term "Record Date" means, prior to the Fixed Rate Date, the Business Day preceding any Interest Payment Date, and after the Fixed Rate Date, the fifteenth (15th) day of the calendar month preceding any Interest Payment Date. The Authority, First Trust of California, National Association, as tender agent (the "Tender Agent"), the Trustee, any paying agent, and any agent of the Authority, the Tender Agent or the Trustee may treat the person in whose name this Bond is registered as the owner hereof for the purpose of receiving payment as herein provided and for all other purposes, and the Authority, the Tender Agent, the Trustee, any paying agent or any such agent shall not be affected by notice to the contrary. This Bond, together with the interest and premium (if any) hereon shall not be deemed to constitute a debt or liability of the State or any political subdivision or agency of the State or a pledge of the faith and credit of the State or any political subdivision or agency of the State, but shall be payable solely from the funds provided therefor pursuant to the Indenture. This Bond is only a special, limited obligation of the Authority as provided by the Act and the Authority shall under no circumstances be obligated to pay the principal of, premium, if any, purchase price of, or interest on this Bond, or other costs incident hereto except from the revenues and funds pledged therefor pursuant to the Indenture. Neither the State nor any political subdivision or agency of the State is in any manner obligated to make any appropriation for such payments. The Authority has no taxing power. No member or officer of the Authority, nor any person executing this Bond shall in any event be subject to any personal liability or accountability by reason of the issuance of this Bond. This Bond is one of a duly authorized issue of bonds of the Authority designated as captioned above (the "Bonds") pursuant to the provisions of the Act, and pursuant to an indenture of trust, dated as of August 1, 1997, between the Authority and the Trustee (the "Indenture"). The Bonds are issued for the purpose of making a loan to Advanced Aerodynamics and Structures, Inc., a corporation duly organized and existing under the laws of the State of Delaware (the "Borrower"), to assist in the financing of a Project (as such term is defined in the Indenture) owned by the Borrower, pursuant to a loan agreement, dated as of August 1, 1997, between the Authority and the Borrower (the "Agreement"), for the purposes and on the terms and conditions set forth therein. The payment of principal of and interest on the Bonds is secured by an irrevocable Letter of Credit issued by The Sumitomo Bank, Limited, acting through its Los Angeles Branch, (the "Letter of Credit" and the "Bank", A-2 respectively). Such Letter of Credit may be renewed or substituted by a letter of credit of another financial institution or an alternate credit facility as provided in the Agreement and the Indenture. Reference is hereby made to the Indenture (a copy of which is on file at said office of the Trustee) and all indentures supplemental thereto and to the Act for a description of the rights thereunder of the registered owners of the Bonds, of the nature and extent of the security, of the rights, duties and immunities of the Trustee and the Tender Agent and of the rights and obligations of the Authority thereunder, to all the provisions of which Indenture the registered owner of this Bond, by acceptance hereof, assents and agrees. The Bonds and the interest thereon are payable solely from Revenues (as defined in the Indenture) and are secured by a pledge of said Revenues and of amounts held in the funds (except as provided in the Indenture) and accounts established pursuant to the Indenture (including proceeds of the sale of the Bonds), subject only to the provisions of the Indenture permitting the application thereof for the purposes and on the terms and conditions set forth in the Indenture. The Bonds are further secured by an assignment of the right, title and interest of the Authority in the Agreement (to the extent and as more particularly described in the Indenture) and by the Letter of Credit. The Bonds shall bear interest from and including the Date of Delivery of the Bonds to and including a date specified in the Indenture at the rate specified in the Indenture. Thereafter, prior to the Fixed Rate Date or final maturity date, whichever is earlier, the Bonds shall bear interest, calculated on the basis of a year of 365 or 366 days, as appropriate, at a rate per annum equal to the Weekly Interest Rate (as hereinafter defined). Each period from and including the Date of Delivery to and including September 1, 1997 and, thereafter, the period from and including an Interest Payment Date to and including the day next preceding the immediately succeeding Interest Payment Date is herein called an "Interest Period." The Weekly Interest Rate shall be the rate determined by Rauscher Pierce Refsnes, Inc. (together with any successor as Remarketing Agent under the Indenture, the "Remarketing Agent"), on the basis of the examination of Tax-exempt (as defined in the Indenture) obligations comparable to the Bonds known by the Remarketing Agent to have been priced or traded under then prevailing market conditions, to be the minimum interest rate which, if borne by the Bonds, would enable the Remarketing Agent to sell the Bonds on the date such interest rate becomes effective at a price equal to the principal amount thereof plus accrued interest, if any, but in no event exceeding twelve percent (12%); provided, however, that if for any reason a Weekly Interest Rate so determined shall be held to be invalid or unenforceable by a court of law, the Weekly Interest Rate shall be the rate established in accordance with the Indenture. The Remarketing Agent shall determine the Weekly Interest Rate as of the close of business on Tuesday in each calendar week until the earlier of the Fixed Rate Date, or payment in full of the Bonds; provided that if Tuesday in any calendar week shall not be a Business Day then such determination shall be made on the next preceding Business Day, and communicate by telephonic notice such rate to the Trustee (with prompt confirmation in writing). The Weekly Interest Rate so determined shall become effective Wednesday in the week of determination thereof, to and including the following Tuesday irrespective of when the rate was determined by the Remarketing Agent. If the Remarketing Agent shall fail to determine a new Weekly Interest Rate in any week, the previously effective Weekly Interest Rate shall remain in effect for the next succeeding week and shall thereafter be determined in accordance with the Indenture. A-3 Each determination of the Weekly Interest Rate by the Remarketing Agent shall be conclusive and binding on the owners of the Bonds. Anything herein to the contrary notwithstanding, in no event may the interest rate borne by the Bonds exceed twelve percent (12%) per annum or, if lower, the maximum rate of interest which may be charged or collected pursuant to applicable provisions of federal or state law. On any Interest Payment Date, the interest rate on the Bonds may be converted to a fixed annual rate of interest (the "Fixed Interest Rate") upon receipt by the Authority, the Trustee, the Tender Agent, the Bank and the Remarketing Agent not less than 45 days in advance of the date on which the Bonds begin to bear interest at the Fixed Interest Rate (the "Fixed Rate Date") of (i) notice from the Borrower electing to have the interest rate on the Bonds converted to a Fixed Interest Rate, (ii) an opinion of Bond Counsel to the effect that conversion to a Fixed Interest Rate is permitted by the Indenture and the Act and that conversion to the Fixed Interest Rate in accordance with the provisions of the Indenture will not cause interest on the Bonds to not be Tax-exempt and (iii) satisfaction of certain other conditions set forth in the Indenture. After the Fixed Rate Date, interest on the Bonds shall be computed on the basis of a year of 360 days and 12 months of 30 days each. The interest rate on all Bonds from the Fixed Rate Date until the maturity or prior redemption or acceleration thereof shall be a rate per annum equal to the Fixed Interest Rate, which shall be determined as follows on or prior to, but not more than 15 days prior to, the Business Day immediately preceding the Fixed Rate Date. The Remarketing Agent shall specify the Fixed Interest Rate to be borne by the Bonds on and after the Fixed Rate Date. The Fixed Interest Rate shall be the rate, but not exceeding the rate, which at the time of determination thereof in the judgment of the Remarketing Agent, having due regard for prevailing financial market conditions, would be necessary to remarket the Bonds at a price equal to 100% of the principal amount thereof on the Fixed Rate Date. If on the date of determination by the Remarketing Agent of the Fixed Interest Rate, the Fixed Interest Rate so determined is held by a court to be invalid or unenforceable, then the Fixed Interest Rate shall be a rate determined by the Remarketing Agent, not less than 90% or more than 130% of the "Alternate Fixed Rate," which in the judgment of the Remarketing Agent, having due regard for prevailing market conditions, would be the minimum rate at which owners of the Bonds would be able to sell the Bonds at a price equal to the principal amount thereof on the Fixed Rate Date. The Alternate Fixed Rate shall be determined by the Remarketing Agent and shall be a rate per annum based upon yield evaluations at par of Tax-exempt securities having a remaining term equal, as nearly as practicable, to the time remaining until the maturity of the Bonds of not less than five Component Issues (as defined in the Indenture) selected by the Remarketing Agent each of which would be rated by either Moody's Investors Service, Inc. or Standard & Poor's Ratings Group in a long-term debt rating category which is the same as, or is immediately proximate to, the long-term debt rating category which will be assigned to the Bonds after the Fixed Rate Date. Anything to the contrary herein notwithstanding, the Fixed Interest Rate shall not exceed twelve percent (12%) per annum. If, after the Fixed Rate Date the Bonds shall fail to be converted to a Fixed Interest Rate, the Bonds will continue to earn interest at the Weekly Interest Rate as provided in the Indenture and the registered owners shall be notified thereof. At least thirty (30) days prior to the Fixed Rate Date, the Trustee shall give an irrevocable notice to the registered owners of conversion of the Weekly Interest Rate borne by the Bonds to the Fixed Interest Rate. Such notice shall (i) specify the proposed Fixed Rate Date, (ii) require owners of all of the Outstanding Bonds to tender their Bonds for purchase on the Fixed Rate Date and (iii) state A-4 that all Outstanding Bonds not purchased on or before the Fixed Rate Date pursuant to the Indenture will be deemed to be purchased on the Fixed Rate Date at a price equal to the principal amount thereof, plus unpaid interest, if any, accrued to such date. Any Bond purchased by the Tender Agent from the date notice of the proposed Fixed Rate Date is given to registered owners through the Fixed Rate Date shall be remarketed at the Weekly Interest Rate for a period up to and including the Fixed Rate Date; provided, however, that all Bonds remarketed from the date notice of the proposed Fixed Rate Date is given to an owner through the Fixed Rate Date shall be tendered by the owner thereof on the Fixed Rate Date pursuant to the provisions of the Indenture. The Bonds are also subject to mandatory tender for purchase on the date an alternate letter of credit is substituted for the Letter of Credit (the "Letter of Credit Substitution Date"). The Fixed Rate Date and the Letter of Credit Substitution Date are also referred to as the "Mandatory Tender Date." All Bonds which on the Mandatory Tender Date have not been tendered for purchase ("Non-Tendered Bonds"), shall be deemed purchased by the Tender Agent on the Mandatory Tender Date at a price of the principal amount thereof plus unpaid interest, if any, accrued to such date. Replacement bonds for the Non-Tendered Bonds may be remarketed and delivered to new owners as instructed by the Borrower or the Remarketing Agent. The Tender Agent shall hold in escrow for the owners of the Non-Tendered Bonds the purchase price thereof, and after the Mandatory Tender Date such owners will no longer be entitled to any of the benefits of the Indenture except for the payment of such purchase price. The Indenture provides that prior to the Fixed Rate Date, the Bonds may be delivered by the owners thereof to the Tender Agent at its principal corporate trust office in San Francisco, California or at such other place as the Tender Agent may designate in writing to the owners. Any Bond so delivered or notice with respect to which is received shall be purchased by the Tender Agent on demand of the owner thereof on the close of any Business Day at a purchase price equal to the principal amount thereof plus accrued interest to but not including the date of purchase (unless such date is an Interest Payment Date, in which case the purchase price will be the principal amount of such Bond) upon: (A) delivery to the Tender Agent of an irrevocable written notice by 4:00 p.m., California time, which states (i) the name and address of the registered owner, (ii) the number or numbers of the Bond or Bonds to be purchased, (iii) the aggregate principal amount of the Bond or Bonds to be purchased, and (iv) the date on which the Bond is or Bonds are to be purchased, which date shall be a Business Day not prior to the seventh (7th) calendar day next succeeding the date of delivery of such notice; and (B) delivery to the Tender Agent at or prior to 10:00 a.m., California time, on the Purchase Date specified in the aforesaid notice, of the Bond or Bonds to be tendered; provided, however, that any Bond for which a notice of the exercise of the purchase option has been given as provided in subsection (A) above and which is not so delivered shall be deemed delivered on the date of purchase and shall be purchased in accordance with the Indenture. The Bonds are subject to redemption by the Authority upon the following terms in increments of $5,000, provided that in the event of redemption of less than all of the Bonds, the amount which remains outstanding shall be in Authorized Denominations (as defined in the Indenture): A-5 (i) The Bonds are not subject to sinking fund redemption. (ii) On or prior to the Fixed Rate Date, the Bonds are subject to redemption on any Interest Payment Date, in whole or in part, to the extent of prepayments of amounts due under the Agreement made at the option of the Borrower, with the written approval of the Bank, at a redemption price of 100% of the principal amount of the Bonds redeemed, plus interest accrued thereon to the redemption date. (iii) The Bonds Outstanding on the date of the occurrence of a Determination of Taxability (as defined in the Indenture) shall be redeemed in whole, at a price of 100% of the principal amount thereof plus interest accrued thereon to the redemption date, at any time within 60 days after such occurrence. IF THE LIEN OF THE INDENTURE IS DISCHARGED PRIOR TO THE OCCURRENCE OF A DETERMINATION OF TAXABILITY THE BONDS SHALL NOT BE REDEEMED AS DESCRIBED HEREIN.
