(d) For all purposes of this Indenture, unless the context otherwise requires, all provisions relating to the redemption of Bonds shall relate, in the case of any Bond redeemed or to be redeemed only in part, to the portion of the principal of such Bond which has been or is to be redeemed.

(e) Notwithstanding any other provision of this Indenture, (1) Bank Bonds eligible for redemption must be selected for redemption before any other eligible Bonds are selected for redemption, and (2) with respect to Bonds in Direct Purchase Mode, the election to exercise any right of optional redemption shall be evidenced by notice to the Trustee and the Purchaser Agent from an Authorized Corporation Representative, which notice must be received by the Trustee and Purchaser Agent at least 10 days prior to the date fixed for redemption (unless a shorter notice is acceptable to the Trustee), and must contain the information specified in Section 5.3, and if less than all such Bonds Outstanding are to be redeemed, the principal amount of Bonds of each Maturity to be redeemed may be specified by the Corporation and the Holder of such Bonds by notice delivered to the Trustee not less than 10 days before the date fixed for redemption (unless a shorter notice is acceptable to the Trustee), or in the absence of timely receipt by the Trustee of such notice, shall be selected by the Trustee by lot or by such other method as the Trustee shall deem fair and appropriate; provided, however, that the principal amount of Bonds of each Maturity to be redeemed may not be larger than the principal amount of Bonds of such Maturity then eligible for redemption and may not be smaller than the smallest Authorized Denomination.

SECTION 5.5 Notice of Redemption

(a) Unless waived by the Holders of all Bonds then Outstanding to be redeemed, notice of redemption shall be given by registered or certified mail, mailed not less than 30 nor more than 60 days

prior to the redemption date, to each Holder of Bonds to be redeemed, at his address appearing in the Bond Register.

(b) All notices of redemption shall state:

(1) the redemption date,

(2) the redemption price,

(3) the principal amount of Bonds to be redeemed, and, if less than all Outstanding Bonds are to be redeemed, the identification (and, in the case of partial redemption, the respective principal amounts) of the Bonds to be redeemed,

(4) that on the redemption date the redemption price of each of the Bonds to be redeemed will become due and payable and that the interest thereon shall cease to accrue from and after said date, and

(5) the place or places where the Bonds to be redeemed are to be surrendered for payment of the redemption price.

(c) Notice of redemption of Bonds to be redeemed at the option of the Board shall be given by the Board or, at the Board’s request, by the Trustee in the name and at the expense of the Board. Notice of redemption of Bonds in accordance with the mandatory redemption provisions of the Bonds shall be given by the Trustee in the name and at the expense of the Board.

(d) The Board and the Trustee shall, to the extent practical under the circumstances, comply with the standards set forth in Securities and Exchange Commission’s Exchange Act Release No. 23856 dated December 3, 1986, regarding redemption notices, provided that their failure to do so shall not in any manner defeat the effectiveness of a call for redemption if notice thereof is given as prescribed in this Section.

(e) Notwithstanding the foregoing, during the Direct Purchase Mode, notice of redemption of the Bonds shall be given directly by the Corporation to the Purchaser Agent and the Trustee at the time and in the manner required by Section 5.4(e)(2).

SECTION 5.6 Deposit of Redemption Price

On the applicable redemption date, an amount of money sufficient to pay the redemption price of all the Bonds which are to be redeemed on that date shall be deposited with the Trustee. Such money shall be held in trust for the benefit of the persons entitled to such redemption price and shall not be deemed to be part of the Trust Estate.

SECTION 5.7 Bonds Payable on Redemption Date

(a) Notice of redemption having been given as aforesaid, the Bonds to be redeemed shall, on the redemption date, become due and payable at the redemption price therein specified and from and after such date (unless the Board shall default in the payment of the redemption price) such Bonds shall cease to bear interest. Upon surrender of any such Bond for redemption in accordance with said notice such Bond shall be paid by the Board at the redemption price. Installments of interest due on or prior to the redemption date shall be payable to the Holders of the Bonds registered as such on the relevant Record Dates according to the terms of such Bonds.

(b) If any Bond called for redemption shall not be paid upon surrender thereof for redemption, the principal (and premium, if any) shall, until paid, bear interest from the redemption date at the Post-Default Rate.

SECTION 5.8 Bonds Redeemed in Part

Unless otherwise provided herein, any Bond which is to be redeemed only in part shall be surrendered at the Office of the Trustee with all necessary endorsements for transfer, and the Board shall execute and the Trustee shall authenticate and deliver to the Holder of such Bond, without service charge, a new Bond or Bonds of the same Maturity and of any Authorized Denomination or Denominations as requested by such Holder in aggregate principal amount equal to and in exchange for the unredeemed portion of the principal of the Bond surrendered.

SECTION 5.9 Redemption of Bonds in Direct Purchase Mode

Notwithstanding the foregoing, payment of the redemption price of any Bond in Direct Purchase Mode shall be payable directly by the Corporation to the Purchaser Agent by wire transfer or such other method as the Corporation and the Purchaser Agent shall agree.

ARTICLE 6

Specific Terms for Bonds

SECTION 6.1 Specific Title and Terms

(a) Title and Amount.

(1) The Bonds shall be entitled “Recovery Zone Facility Revenue Bonds (Olin Corporation Project), Series 2010.” The aggregate principal amount of the Bonds which may be authenticated and delivered and Outstanding is limited to $41,000,000.

(2) The Bonds will be issued as a “draw-down loan” as described in § 1.150-1(c)(4) of the Regulations. On each date during the Draw-Down Period on which the Trustee receives from the Purchaser Agent funds for deposit into the Costs of Issuance Fund or the Acquisition Fund in accordance with Section 6.8, the aggregate amount of such receipts shall constitute an Advance under this Indenture. Each Advance will increase the Outstanding Principal Amount of the Bonds, as indicated in the instructions provided to the Trustee under Section 6.8. Each increase in the Outstanding Principal Amount of a Bond as the result of additional Advances shall be recorded on the Bond by the Trustee (or if the Bond is in Direct Purchase Mode, by the Purchaser Agent); provided, however, that failure of the Trustee (or Purchaser Agent) to record any Advance on a Bond shall not in any way compromise, reduce or eliminate in any way the Board’s obligations under this Indenture with respect to the full Outstanding Principal Amount of such Bond, based upon the actual amount of proceeds delivered to the Trustee with respect thereto.

(3) Notwithstanding any other provision in this Indenture, (1) the Outstanding Principal Amount of the Bonds may not exceed the aggregate amount of that may be authenticated and delivered under Section 6.1(a), and (2) no additional Advances may be made after the expiration of the Draw-Down Period. If less than $41,000,000 of aggregate Advances have been made under the Bonds when the Draw-Down Period expires, after giving effect to any extensions thereof, the Bonds shall be Outstanding at that time in an aggregate principal amount equal to Outstanding Principal Amount (as defined herein), computed using the last day of the Draw-Down Period as the determination date, and no further Advances shall be made under this Indenture after such date.

(b) Authorized Denominations. The Bonds shall be in the following denominations: (1) for Bonds in the Weekly Rate Mode and Bonds in the Term Rate Mode for a Term Rate Period of 270 days or less, $100,000 or any larger amount that is a multiple of $5,000, (2) for Bonds in the Term Rate Mode for a Term Rate Period of more than 270 days, $5,000 or any multiple thereof, and (3) for Bonds in the Direct Purchase Mode, whatever principal amount of the Bonds is then held by each Purchaser of the Bonds.

(c) Form and Number. The Bonds shall be issuable as registered bonds without coupons in Authorized Denominations. The Bonds shall be numbered separately from R-1 upward. The Bonds and the certificate of authentication shall be substantially as set forth in Exhibit A with such appropriate insertions, omissions, substitutions and other variations as are required or permitted by this Indenture.

(d) Maturity. The Bonds shall mature on December 1, 2035; provided, however, that the Trustee shall assign Serial Maturities to all Outstanding Bonds upon request of the Board, subject to the following requirements:

(1) The Board shall deliver a Favorable Tax Opinion to the Trustee.

(2) Assignment of Serial Maturities may only be effected in connection with a Conversion of all Outstanding Bonds to a Term Rate for Term Rate Periods extending to their respective Maturities.

(3) Serial Maturities may include one or more term bonds, so long as the resulting schedule for retirement of principal corresponds to the schedule for principal retirement contained in this Indenture (taking into account the mandatory redemption schedule).

(4) The Trustee shall establish a procedure it determines to be fair and appropriate, by lot or otherwise, for selecting and identifying Bonds to reflect the assignment of Serial Maturities.

(5) The Trustee shall notify Holders of Bonds and Financing Participants of the results of such procedure.

(e) Date. The Bonds shall be dated as of the date of initial delivery of the Bonds.

(f) Interest Rates. Each Bond shall bear interest at the Direct Purchase Rate, the Weekly Rate or the Term Rate, as provided in Section 6.2. All Bonds must be in the same Interest Rate Mode at the same time, and if in the Direct Purchase Mode, must all be in the same Direct Purchase Rate Period, but the Bonds may be in different Interest Rate Modes at the same time, in each case subject to the terms and conditions of Section 6.3 regarding Conversion.. All Bonds shall initially be issued in the Direct Purchase Mode and shall bear interest at a Direct Purchase Variable Rate. The Bonds may from time to time be converted to a different Interest Rate Mode, as provided in Section 6.3 and subject to the limitations set forth above. The Trustee shall specify on each Bond certificate, in the space provided, which Interest Rate Mode is in effect with respect to such Bond. If a Term Rate is in effect with respect to a Bond, the Trustee shall also specify on the certificate for such Bond the Term Rate and the beginning and end of the Term Rate Period. If a Direct Purchase Mode is in effect with respect to a Bond, the Purchaser Agent shall notify the Trustee in writing of the beginning and end of the Direct Purchase Rate Period, and the Trustee shall also specify such dates on the certificate for such Bond when authenticated.

(g) Interest Payment Dates. Interest shall be payable in arrears on the following dates:

(1) with respect to interest on any Bond payable at the Weekly Rate, (A) on the first Business Day of each month and (B) on the effective date of Conversion of such Bond from the Weekly Rate Mode to another Interest Rate Mode;

(2) with respect to interest on any Bond payable at a Term Rate for a Term Rate Period of 270 days or less, on the last day of the Term Rate Period;

(3) with respect to interest on any Bond payable at the Term Rate for any Term Rate Period of more than 270 days, (A) on the first Business Day of the calendar months during which there occurs the six-month anniversary and the one-year anniversary of the Conversion to such Term Rate Period and semi-annually on the first Business Day of each such month thereafter, and (B) on the last day of the Term Rate Period; and

(4) with respect to any Bond payable at the Direct Purchase Rate, (A) on the first Business Day of each calendar month, (B) on the Business Day immediately succeeding the last day of each Direct Purchase Rate Period, and (C) on the effective date of Conversion of such Bond from the Direct Purchase Mode to another Interest Rate Mode.

(h) Regular Record Date. The interest due on any Interest Payment Date for the Bonds shall be payable to the Holder as of the Regular Record Date for such Interest Payment Date. The Regular Record Date for the payment of interest on the Bonds shall be: (1) with respect to any Weekly Rate Interest Payment Date, the day immediately prior to such Interest Payment Date, (2) with respect to any Term Rate Interest Payment Date for a Term Rate Period of 1 year or less, the day immediately prior to such Interest Payment Date, (3) with respect to any Term Rate Interest Payment Date for a Term Rate Period of more than 1 year, the 15th day (whether or not a Business Day) of the month next preceding such Interest Payment Date, and (4) with respect to any Direct Purchase Interest Payment Date, the day immediately prior to such Interest Payment Date.

(i) Computation of Interest Accrual. The Bonds shall bear interest from their date, or the most recent date to which interest has been paid or duly provided for, at the applicable rate per annum set forth in this Article. Interest at the Weekly Rate and interest at the Term Rate for any Term Rate Period of 1 year or less shall be computed on the basis of a 365 or 366-day year, as the case may be, for the actual number of days elapsed. Interest at the Term Rate for any Term Rate Period of more than 1 year shall be computed on the basis of a 360-day year with 12 months of 30 days each. Interest at a Direct Purchase Rate shall be computed on the basis of a 360-day year for the actual number of days elapsed.

(j) Interest on Overdue Payments and Upon a Determination of Taxability. Interest shall be payable on overdue principal on the Bonds and (to the extent legally enforceable) on any overdue installment of interest or overdue premium on the Bonds at the Post-Default Rate. Upon a Determination of Taxability, the Bonds shall bear interest at the Taxable Rate, effective on the date determined by the Internal Revenue Service as the date on which the interest on the Bonds became includible in gross income of the Holder.

(k) Redemption Provisions. The Bonds shall be subject to redemption prior to Maturity as follows:

(1) Optional Redemption. Bonds may be redeemed at the option of the Board as follows:

(A) On any date when a Bond is in the Weekly Rate Mode and on any Conversion Date with respect to a Bond, such Bond may be redeemed in whole or in part

at a redemption price equal to 100% of the principal amount to be redeemed plus accrued interest thereon to the date of redemption.

(B) During any Term Rate Period of 5 years or less with respect to a Bond, such Bond shall not be subject to optional redemption. During any Term Rate Period of more than 5 years with respect to a Bond, such Bond may be redeemed in whole or in part on or after the First Optional Call Date (as defined below) at a redemption price equal to 100% of the principal amount to be redeemed plus accrued interest thereon to the date of redemption plus a redemption premium (expressed as a percentage of principal amount redeemed) equal to whichever of the following shall be applicable: 2% if the date of redemption is on or after the First Optional Call Date but prior to the first anniversary of the First Optional Call Date; 1% if the date of redemption is on or after the first anniversary of the First Optional Call Date but prior to the second anniversary of the First Optional Call Date; and without premium if the date of redemption is on or after the second anniversary of the First Optional Call Date. For any Term Rate Period of more than 5 years but not more than 10 years, the First Optional Call Date shall be the fifth anniversary of the beginning of the Term Rate Period. For any Term Rate Period of more than 10 years but not more than 20 years, the First Optional Call Date shall be the anniversary of the beginning of the Term Rate Period that is on or immediately after the midpoint of such Term Rate Period. For any Term Rate Period of more than 20 years, the First Optional Call Date shall be the tenth anniversary of the beginning of the Term Rate Period.

(C) While the Bonds are in the Direct Purchase Mode and bear interest at a Direct Purchase Variable Rate, the Bonds shall be subject to optional redemption before maturity at the direction of the Corporation in whole or in part on any Direct Purchase Interest Payment Date at a redemption price of 100% of the principal amount thereof, plus accrued interest to the redemption date, and without premium. While the Bonds are in the Direct Purchase Mode and bear interest at a Direct Purchase Fixed Rate, the Bonds shall be subject to optional redemption before maturity at the direction of the Corporation in whole or in part on any Direct Purchase Interest Payment Date at a redemption price of 100% of the principal amount thereof, plus accrued interest to the redemption date, plus a premium equal to 5% of the outstanding principal amount of the Bonds so redeemed in the first year following the Conversion Date on which such Direct Purchase Fixed Rate became effective, declining by 1% each year thereafter (but not below zero).

(2) Optional Redemption Upon Occurrence of Certain Calamities. All (but not less than all) Bonds may be redeemed at the option of the Board, at a redemption price equal to 100% of the principal amount to be redeemed plus accrued interest thereon to the redemption date, within 180 days after any of the following shall have occurred:

(A) the Bond-Financed Facilities shall have been damaged or destroyed to such extent that, in the opinion of the Corporation, they cannot be restored within a period of 4 months to substantially the condition thereof immediately prior to such damage or destruction or the Corporation is thereby prevented from carrying on its normal operations at the Bond-Financed Facilities for a period of not less than 4 months; or

carrying on its normal operations at the Bond-Financed Facilities for a period of not less than 4 months; or

(C) the Corporation ceases operation of the Bond-Financed Facilities for a period of 4 months because of a change in technology or in the availability at reasonable cost of labor, raw materials, energy or transportation that, in the opinion of the Corporation, renders the Bond-Financed Facilities uneconomic for their intended use; or

(D) as a result of a change in law or a final order of any court or other governmental authority the Loan Agreement becomes void or unenforceable or impossible of performance or unreasonable burdens or excessive liabilities are imposed on the Corporation that, in the opinion of the Corporation, render the Bond-Financed Facilities uneconomic for their intended use.

SECTION 6.2 Determination of Interest Rates and Term Rate Periods

(a) Weekly Rate. The Weekly Rate shall be a fluctuating rate per annum determined periodically by the Remarketing Agent while Bonds are in the Weekly Rate Mode, subject to the following terms and conditions:

(1) The Weekly Rate shall be determined (A) on the date of Conversion of any Bonds to the Weekly Rate Mode, and (B) on the last Business Day before each Thursday.

(2) Interest accrual at the Weekly Rate so determined shall begin on (and shall include) (A) the date of determination, if such date is the date of initial delivery or a Conversion Date, or (B) the Thursday following the date of determination, and shall end on (but shall not include) the next Thursday (or, if sooner, a Conversion Date); provided, however, that if the Remarketing Agent fails to determine the Weekly Rate on any such determination date, the Alternate Rate Index shall be deemed to be the rate determined.

(3) The Weekly Rate with respect to the Bonds shall be determined by the Remarketing Agent and shall be the lowest interest rate that would, in the opinion of the Remarketing Agent, result in the market value of such Bonds being 100% of the principal amount thereof on the date of such determination, taking into account relevant market conditions and credit rating factors as they exist on such date; provided, however, that the Weekly Rate may never exceed the Cap Rate.

(4) On each Weekly Rate determination date the Remarketing Agent shall give telephonic notice to the Trustee of the Weekly Rate so determined. Upon the request of the Holder of any Bond or any Financing Participant, the Trustee shall confirm (by telephone and in writing, if so requested) the Weekly Rate then in effect.

(b) Term Rate and Term Rate Periods. The Term Rate for any Bond in the Term Rate Mode shall be a fixed rate per annum determined by the Remarketing Agent for a Term Rate Period specified for such Bond by the Board, subject to the following terms and conditions:

(1) The duration of a Term Rate Period shall be limited as follows:

(A) A Term Rate Period may be for any period of 30 or more days.

(B) A Term Rate Period (other than a Term Rate Period extending to Maturity) must end on a Business Day. If the final day of a Term Rate Period specified

by the Board, is not in fact a Business Day, then such Term Rate Period shall be deemed to extend to the next day that is a Business Day.

(C) If the Letter of Credit will be in effect during the Term Rate Period, the Term Rate Period must end at least 5 days prior to the Stated Expiration Date of the Letter of Credit.

(D) If the Letter of Credit will be in effect during the Term Rate Period, the maximum number of days of interest payable on any Interest Payment Date during such Term Rate Period must be at least 5 days less than the maximum number of days of interest payable at the Cap Rate pursuant to the Letter of Credit.

(E) If the Letter of Credit will be in effect during the Term Rate Period, the Letter of Credit must provide coverage for payment of the maximum redemption premium on the Bonds.

(F) If a Mandatory Tender occurs pursuant to Section 6.5(a)(3), all Term Rate Periods will end on the Mandatory Tender Date.

(2) After receipt of notice that a Term Rate is to be established with respect to any Bond, but not later than the last Business Day prior to the proposed Conversion Date, the Remarketing Agent shall determine the interest rate for the Term Rate Period, which shall be the lowest interest rate that would, in the opinion of the Remarketing Agent, result in the market value of such Bond being 100% of the principal amount thereof on the date of such determination, taking into account relevant market conditions and credit rating factors as they exist on such date, and assuming that the Term Rate Period began on such date; provided, however, that the Term Rate may not exceed the Cap Rate.

(3) Interest accrued at the Term Rate for any Term Rate Period shall begin on (and shall include) the first day of the Term Rate Period and shall end on (but shall not include) the last day of the Term Rate Period.

(4) The Remarketing Agent shall give telephonic notice to the Trustee of the Term Rate so determined, and shall promptly confirm such notice in writing. Upon the request of the Holder of the Bond or any Financing Participant, the Trustee shall confirm (by telephone and in writing, if so requested) the Term Rate so determined.

(c) Rate Determinations Conclusive. The interest rates determined by the Remarketing Agent as provided in this Section shall be conclusive and binding on the Financing Participants.

(d) Direct Purchase Rate Provisions. The Direct Purchase Rate for any Bond in Direct Purchase Mode shall be a rate per annum set forth in the Direct Purchase Agreement applicable to such Bond, subject to the following terms and conditions:

(1) In connection with the Conversion of Bonds to a Direct Purchase Mode, or the affirmative establishment of a new Direct Purchase Rate Period subsequent to an expiring Direct Purchase Rate Period, the duration of each Direct Purchase Rate Period shall be no less than one hundred eighty (180) days, shall begin on the Conversion Date or the Business Day immediately succeeding the last day of the expiring Direct Purchase Rate Period, and shall end on a day immediately preceding a Direct Purchase Interest Payment Date. The specific dates on which a Direct Purchase Rate Period begins and ends with respect to each Bond in Direct Purchase Mode

shall be specified in such Bond, as authenticated and delivered under Section 6.1(f) of this Indenture.

(2) Bonds in Direct Purchase Mode shall bear interest during each Direct Purchase Rate Period at either a Direct Purchase Fixed Rate or a Direct Purchase Variable Rate (as selected by the Corporation), determined as follows:

(A) A Direct Purchase Fixed Rate shall be a fixed rate of interest effective for the duration of such Direct Purchase Rate Period set forth in the Direct Purchase Agreement and certified to by the Purchasers as the lowest fixed rate of interest that would permit the Bonds to be sold at par, plus accrued interest, on the Conversion Date, in no event to exceed the Cap Rate.

(B) A Direct Purchase Variable Rate shall be a variable rate of interest effective for the duration of such Direct Purchase Rate Period set forth in the Direct Purchase Agreement equal to the sum of LIBOR, plus the Designated Basis Points, which rate shall be certified to by the Purchaser as the lowest rate of interest that would permit the Bonds to be sold at par, plus accrued interest, on the Conversion Date, in no event to exceed the Cap Rate.

The specific Direct Purchase Fixed Rate or Direct Purchase Variable Rate applicable for each Direct Purchase Rate Period shall be specified on the Bond authenticated and delivered with respect to such Direct Purchase Rate Period under Section 6.1(f) of this Indenture. Notwithstanding the foregoing, in no event shall any Bond commence bearing interest at the new Direct Purchase Rate for a new Direct Purchase Rate Period unless and until a Favorable Tax Opinion has been delivered to the Purchaser Agent and the Corporation with respect to such change.

(3) In the event a Purchaser has not elected to tender its Bonds on the Business Day immediately succeeding the Initial Direct Purchase Rate Period pursuant to Section 6.4(a) hereof and the Borrower has not directed a Conversion of the Interest Rate Mode, the non-tendered Bonds shall continue to bear interest at the Direct Purchase Rate then in effect for a Direct Purchase Rate Period of one year. Thereafter any time the Bonds are in the Direct Purchase Rate Mode, in the event the Holder thereof has not elected to tender its Bonds on the Business Day immediately succeeding such Direct Purchase Rate Period pursuant to Section 6.4(a) hereof and the Borrower has not directed a Conversion of the Interest Rate Mode, the Bonds shall continue to bear interest at the Direct Purchase Rate then in effect for successive one year Direct Purchase Rate Periods.

SECTION 6.3 Conversion of Interest Rate Mode

(a) Optional Conversion to Another Interest Rate Mode. At the option of the Board, any Bond may be converted from one Interest Rate Mode to another Interest Rate Mode, a new Term Rate Period may be established upon the expiration of any existing Term Rate Period and one Direct Purchase Rate Period may be established upon the expiration of an existing Direct Purchase Rate Period, subject to the following terms and conditions:

(1) The Board must give the other Financing Participants notice of such conversion not less than 25 days (if the Bonds are in Weekly Rate Mode or Term Rate Mode) or 15 days (if the Bonds are in Direct Purchase Mode) prior to the proposed Conversion Date. Such notice must specify (A) the Interest Rate Mode to which such Bond is being converted, (B) the Term Rate Period or the Direct Purchase Rate Period, if converting to a Term Rate Mode or Direct

Purchase Mode, as applicable, (C) the Term Rate or the Direct Purchase Rate, if converting to a Term Rate Mode or Direct Purchase Mode, as applicable, (D) the Conversion Date and (E) the principal amount and the certificate number of the Bond for which the Conversion is requested.

(2) If the Bond is being converted from the Weekly Rate Mode, the Conversion Date may be any Business Day. If the Bond is being converted from the Term Rate Mode, the Conversion Date must be the last day of the Term Rate Period then in effect. If the Bond is being converted from Direct Purchase Mode, the Conversion Date must be the last Business Day of the Direct Purchase Rate Period then in effect.

(3) If any Bond is converted to or from Direct Purchase Mode or is converted from one Direct Purchase Rate Period to a new Direct Purchase Rate Period, all Bonds must be converted to or from such Direct Purchase Mode or to such new Direct Purchase Rate Period, as applicable.

(4) On the proposed Conversion Date the Trustee must receive a Favorable Tax Opinion.

A notice from the Board of conversion to the Term Rate Mode may provide that successive Term Rate Periods of specified length shall be established with respect to a Bond. If such a notice is delivered, no additional notice of conversion shall be required from the Board prior to the Term Rate Periods so specified. Any such notice may be revoked as provided in Section 6.3(b), but the revocation shall be applicable only with respect to Term Rate Periods that would have commenced after the date of the notice of revocation.

A notice from the Board of conversion to the Direct Purchase Rate Mode may provide that successive Direct Purchase Rate Periods of specified length shall be established with respect to a Bond. If such a notice is delivered, no additional notice of conversion shall be required from the Board prior to the Direct Purchase Rate Periods so specified. Any such notice may be revoked as provided in Section 6.3(b), but the revocation shall be applicable only with respect to Direct Purchase Rate Periods that would have commenced after the date of the notice of revocation.

(b) Revocation of Election. The Board may, at its option, revoke the election to convert a Bond from the Weekly Rate Mode to Term Rate Mode or to Direct Purchase Mode (or to establish successive Term Rate Periods or successive Direct Purchase Rate Periods) by notice delivered to the other Financing Participants before such Bond is delivered to the Holder in the new Interest Rate Mode, but in any event no later than the Trustee’s close of business on the Conversion Date. In addition, the election to convert shall automatically be deemed revoked if (1) the Remarketing Agent fails to establish the Term Rate or the Trustee does not receive confirmation from the Remarketing Agent that such Bond has been remarketed in the Term Rate Mode, or (2) the Corporation fails to deliver to the Trustee an executed Direct Purchase Agreement with respect to the proposed Direct Purchase Mode. The Board’s right to revoke an election pursuant to this Section shall not affect any rights or remedies that the Remarketing Agent may have against the Board pursuant to any bond purchase agreement, placement or remarketing agreement, or other agreement entered into by the Remarketing Agent in connection with the proposed Conversion.

(c) Mandatory Tender Notwithstanding Failed Conversion. If a notice of Mandatory Tender is given by the Trustee in connection with a proposed Conversion of a Bond to another Interest Rate Mode, such Bond shall be subject to a Mandatory Tender on such date notwithstanding the revocation of the election to effect such Conversion or the failure to satisfy the conditions for such conversion.

(d) Interest Rate Following Failed Conversion. If the conditions for a Conversion are not satisfied on the applicable Conversion Date and the Bonds are tendered by Holders in accordance with Section 6.3(c), (1) Bonds in Weekly Rate Mode may become Bank Bonds or may be remarketed in accordance with Section 6.6, (2) Bonds in a Term Rate Mode shall bear interest at the Post-Default Rate until no longer Outstanding or successfully converted to another Interest Rate Mode, and (3) Bonds in Direct Purchase Mode shall bear interest at the Post-Default Rate until the earliest of (A) the Bonds are no longer Outstanding, (B) the Bonds are successfully Converted to another Interest Rate Mode, and the Purchase Price plus any accrued and unpaid interest (including without limitation, interest accruing at the Post Default Rate) has been paid to the tendering Holders, (C) with the agreement and consent of the Purchasers, the Bonds commence a new Direct Purchase Mode or Direct Purchase Rate Period, or (D) the Purchase Price plus any accrued and unpaid interest (including without limitation, interest accruing at the Post Default Rate) has been paid to the tendering Holders. Notwithstanding application of the Post-Default Rate under this paragraph 6.3(d), a Mandatory Tender in connection with a failed Conversion shall not constitute an Event of Default under this Indenture unless provided separately in a Bank Security Document or Direct Purchaser Security Document.

SECTION 6.4 Optional Tenders

(a) (1) The Holder of any Bond in Weekly Rate Mode shall have the right to tender such Bond to the Trustee for purchase in whole or in part on any Business Day and (2) the Holder of any Bond in Direct Purchase Mode shall have the right to tender such Bond to the Trustee for purchase, in whole but not in part, on the Business Day immediately succeeding the last day of any Direct Purchase Rate Period. In order to exercise such option with respect to any Bond, the Holder thereof must deliver notice thereof to the Trustee, as provided below in this Section, at least 7 days prior to the proposed Optional Tender Date so long and the Bonds are in the Weekly Rate Mode, and at least 120 days prior to the proposed Optional Tender Date so long as the Bonds are in the Direct Purchase Mode.

(b) Any such notice of Optional Tender must be duly executed by the Bondholder and must specify (1) the name of the registered Holder of the Bond to be tendered for purchase, (2) the Optional Tender Date, (3) the certificate number and principal amount of such Bond, and (4) the principal amount of such Bond to be purchased (if the Bonds are in the Weekly Rate Mode and such amount is less than the entire principal amount, both the amount to be purchased and the amount remaining must be in an Authorized Denomination). The notice of Optional Tender must be substantially as set forth in Exhibit 6.4(b) or in such other form as shall be acceptable to the Trustee. The Trustee shall promptly forward a copy of such notice to the other Financing Participants.

(c) If any notice of Optional Tender specifies an Optional Tender Date that is not a Business Day, then such notice shall be deemed to specify the next following Business Day as the Optional Tender Date. If the Bonds are in the Weekly Rate Mode, unless a notice of Optional Tender indicates that less than the entire principal amount of the Bond is being tendered for purchase, the Holder will be deemed to have tendered the Bond in its entire principal amount for purchase.

(d) Upon delivery of a written notice of Optional Tender, the election to tender shall be irrevocable and binding upon such Holder and may not be withdrawn. The Trustee shall, in its sole discretion, determine whether, with respect to any Bond, the Holder thereof shall have properly exercised the option to have his Bond purchased pursuant to this Section.

(e) If a written notice of tender shall have been duly given with respect to any Bond, the Holder of such Bond shall deliver such Bond to the Office of the Trustee on the Optional Tender Date, together with all necessary endorsements for transfer. If the Bonds are in Weekly Rate Mode and only a portion of the Bonds is to be purchased (as a result of the exercise of the Optional Tender right only with respect to such portion), the Board shall execute and the Trustee shall authenticate and deliver to the

Holder of such Bond, without service charge, a new Bond or Bonds of the same Maturity, series and interest rate and of any Authorized Denomination or Denominations as requested by such Holder in aggregate principal amount equal to and in exchange for the unpurchased portion of the principal amount of the Bond surrendered. Any Bond (or portion thereof) that is to be so purchased but that is not so delivered to the Trustee (an “Unsurrendered Bond”) shall nevertheless be deemed to have been tendered by the Holder thereof on the Optional Tender Date.

(a) The Board may provide for the payment of any Bond by establishing a trust for such purpose with the Trustee and depositing therein cash and/or Federal Securities which (assuming the due and punctual payment of the principal of and interest on such Federal Securities, but without reinvestment) will provide funds sufficient to pay the Debt Service on such Bond as the same becomes due and payable until the Maturity or redemption of such Bond; provided, however, that:

(1) Such Federal Securities must not be subject to redemption prior to their respective maturities at the option of the issuer of such Securities.

(2) If such Bond is to be redeemed prior to its Maturity, either (A) the Trustee shall receive evidence that notice of such redemption has been given in accordance with the provisions of this Indenture and such Bond or (B) the Board shall confer on the Trustee irrevocable authority for the giving of such notice on behalf of the Board.

(3) If such trust relates to a Bond, such trust must be established only when such Bond is in the Term Rate Mode, and such Bond must mature or be called for redemption (if permitted by this Indenture) on or before the last day of the Term Rate Period then in effect.

(4) Prior to the establishment of such trust the Trustee must receive (A) an Opinion of Counsel acceptable to the Trustee and each Rating Agency that maintains a rating with respect to the Bonds stating in effect that upon the occurrence of an Act of Bankruptcy with respect to the Board, money and investments in such trust will not be recoverable from the Trustee or Bondholders under provisions of the Federal Bankruptcy Code relating to voidable preferences and (B) a Favorable Tax Opinion.

(5) Prior to the establishment of such trust the Trustee must receive verification satisfactory to the Trustee demonstrating that the principal and interest payments on the Federal Securities in such trust, without reinvestment, together with the cash balance in such trust remaining after purchase of such Securities, will be sufficient to make the required payments from such trust.

(b) Any trust established pursuant to this Section may provide for payment of less than all Bonds outstanding or less than all Bonds of any remaining Maturity.

(c) If any trust provides for payment of less than all Bonds of a Maturity, the Bonds of such Maturity to be paid from the trust shall be selected by the Trustee by lot by such method as shall provide for the selection of portions (in Authorized Denominations) of the principal of Bonds of such Maturity of a denomination larger than the smallest Authorized Denomination. Such selection shall be made within 7 days after such trust is established. This selection process shall be in lieu of the selection process otherwise provided with respect to redemption of Bonds. After such selection is made, Bonds that are to be paid from such trust (including Bonds issued in exchange for such Bonds pursuant to the transfer or exchange provisions of this Indenture) shall be identified by a separate CUSIP number or other designation satisfactory to the Trustee. The Trustee shall notify Holders whose Bonds (or portions thereof) have been selected for payment from such trust and shall direct such Bondholders to surrender their Bonds to the Trustee in exchange for Bonds with the appropriate designation. The selection of Bonds for payment from such trust pursuant to this Section shall be conclusive and binding on the Financing Participants.

(d) Cash and/or Federal Securities deposited with the Trustee pursuant to this Section shall not be a part of the Trust Estate but shall constitute a separate, irrevocable trust fund for the benefit of the Holder of the Bond to be paid from such fund.

SECTION 14.3 Direct Purchase Mode

Notwithstanding any other provision of this Article to the contrary, while the Bonds are in the Direct Purchase Mode, the Bonds shall be deemed paid and the lien of this Indenture discharged upon the payment or provision for the payment of the Bonds in any manner reasonably satisfactory to the Purchaser Agent.

ARTICLE 15

The Letter of Credit and

Rights of the Bank

SECTION 15.1 Beneficiary of a Letter of Credit

Any Letter of Credit delivered to the Trustee under this Article 15 shall be held by the Trustee for the sole benefit of Holders of the Bonds specified in such Letter of Credit.

SECTION 15.2 Letters of Credit; Substitute Letters of Credit

(a) Each Letter of Credit delivered to the Trustee must meet the following criteria:

(1) The effective date of the Letter of Credit must be on or before the date of delivery to the Trustee.

(2) The Letter of Credit must provide for payment of interest on the Bonds in an amount equal to interest at the Cap Rate for a number of days equal to the greater of:

(A) 35 days, or

(B) the sum of 10 days plus the greatest number of days between Interest Payment Dates with respect to any Bond then Outstanding in the Term Rate Mode.

(3) The Letter of Credit must have a Stated Expiration Date that is (A) if the Letter of Credit supports Bonds in Weekly Rate Mode, not sooner than 364 days after its effective date and (B) if the Letter of Credit supports Bonds in a Term Rate Mode, not sooner than the last day of the Term Rate Period for which the Letter of Credit is delivered.

(4) If the Letter of Credit will be effective during a Term Rate Period when the Bonds are subject to optional redemption, the Letter of Credit must provide coverage for payment of the maximum redemption premium on the Bonds.

(b) The Corporation may at any time and from time to time deliver another irrevocable letter of credit (a “Substitute Letter of Credit”) to the Trustee in substitution for the Letter of Credit then held by the Trustee (the “Existing Letter of Credit”), provided that:

(1) Such Substitute Letter of Credit must be substantially in the same form and of the same tenor as Existing Letter of Credit, except for such changes or modifications as are necessary in order to comply with the applicable conditions set forth in Section 15.2(a).

(2) Simultaneously with the delivery of such Substitute Letter of Credit, the Corporation delivers to the Trustee any Related Documentation required by Section 15.2(d).

(3) The Corporation gives the other Financing Participants 30 days’ prior notice of such substitution, which notice must specify a Business Day on which such substitution will occur.

(4) No substitution is permitted when Bonds are in the Term Rate Mode unless

(A) the substitution date will also be the last day of the Term Rate Period for all Bonds then in the Term Rate Mode or

(B) all Bonds are in the Term Rate Mode and the Substitute Letter of Credit is accompanied by either (i) if any Rating Agency maintains a rating with respect to the Bonds at the time of such substitution, evidence from each such Rating Agency to the effect that such substitution will not, by itself, result in a reduction or withdrawal of its rating then assigned to the Bonds or (ii) if no Rating Agency maintains a rating with respect to the Bonds at the time of substitution, evidence that long-term deposits of the issuer of such Substitute Letter of Credit are rated in one of the three highest rating categories of at least one Rating Agency.

(5) For Bonds in the Weekly Rate Mode, a Mandatory Tender is required on the substitution date pursuant to Section 6.5(a)(5). If all or a portion of the Bonds are in the Term Rate Mode and the proposed substitution date is also the last day of the Term Rate Period for all such Bonds, a Mandatory Tender is required on the substitution date pursuant to Section 6.5(a)(2). If all Bonds are in the Term Rate Mode and the proposed substitution date is not the last day of the Term Rate Period for all such Bonds, a substitution is permitted, without a Mandatory Tender, only if the rating conditions of Section 15.2(b)(4)(B) are satisfied.

(6) Such Substitute Letter of Credit must have a Stated Expiration Date that is (A) for Bonds in Weekly Rate Mode, not sooner than 364 days after its effective date and (B) for Bonds in Term Rate Mode, the Substitute Letter of Credit must have a Stated Expiration Date not sooner than the Stated Expiration Date of the Existing Letter of Credit.

(7) Any draws that, under the terms of the Indenture, are to be made on an Existing Letter of Credit on or prior to the effective date of a Substitute Letter of Credit shall be made under the Existing Letter of Credit. At the close of business on the effective date of any Substitute Letter of Credit, the Trustee shall return the Existing Letter of Credit to the issuer thereof, provided that any draws on such Existing Letter of Credit made on or prior to such date have been honored.

(8) If the Trustee accepts a Substitute Letter of Credit, the Trustee shall send written notice of such substitution to the Bondholders; provided, however, that if a Mandatory Tender is required in connection with such substitution, no further notice of the substitution shall be required.

(c) If a Substitute Letter of Credit and the Related Documentation are not delivered to the Trustee at least 20 days prior to the Stated Expiration Date of the then Existing Letter of Credit, the Bonds shall be subject to a Mandatory Tender, as provided in Section 6.5(a)(5).

(d) Each Letter of Credit or Substitute Letter of Credit delivered to the Trustee must be accompanied by the following (herein referred to as the “Related Documentation”), to the extent applicable:

(1) A Favorable Tax Opinion.

(2) An Opinion of Counsel stating in effect that such Letter of Credit or Substitute Letter of Credit is a valid and binding obligation of the issuer thereof.

(3) An Opinion of Counsel stating in effect that the delivery of the Letter of Credit or Substitute Letter of Credit complies with the applicable provisions of this Indenture.

(4) An Opinion of Counsel stating in effect that upon the occurrence of an Act of Bankruptcy with respect to the Board or the Corporation, money drawn under such Letter of

Credit or Substitute Letter of Credit will not be recoverable from the Trustee or Bondholders under provisions of the Federal Bankruptcy Code relating to voidable preferences.

(5) A certificate from the Bank that issued the Existing Letter of Credit stating in effect that all amounts due to the Bank under the Bank Reimbursement Agreement have been paid in full.

(e) The term of any Letter of Credit already held by the Trustee may be extended by the Bank by delivery to the Trustee of an amendment to such Letter of Credit (or an amended, restated or replacement Letter of Credit) containing the new Stated Expiration Date. Such Letter of Credit, as so amended, restated or replaced, shall not be considered a Substitute Letter of Credit and shall not require the delivery of Related Documentation.

SECTION 15.3 Cancellation of Letter of Credit

(a) A Letter of Credit shall be cancelled and surrendered by the Trustee to the Bank under the following circumstances:

(1) An Existing Letter of Credit shall be cancelled upon the Trustee’s acceptance of a Substitute Letter of Credit in substitution for the Existing Letter of Credit in accordance with Section 15.2.

(2) A Letter of Credit may be cancelled at the request of the Corporation (A) with respect to all Outstanding Bonds on any Conversion Date on which all Outstanding Bonds are Converted to an Interest Rate Mode in which the Bonds will not be supported by a Letter of Credit, and (B) with respect to the Bonds, on any Conversion Date on which all Outstanding Bonds are Converted to an Interest Rate Mode in which the Bonds will not be supported by a Letter of Credit.

(3) The Letter of Credit shall be cancelled when all Indenture Indebtedness is Fully Paid.

(b) The Letter of Credit may not be cancelled with respect to only a portion of the Bonds, it being intended that if a Letter of Credit is in effect with respect to the Bonds, all Bonds will be secured by the Letter of Credit.

SECTION 15.4 Amendment of Letter of Credit

The Trustee may consent to amendments of the Letter of Credit that do not, in the judgment of the Trustee, adversely affect the interests of the Holders of the Bonds supported by the Letter of Credit, provided that such amendments are consistent with the required provisions for a Substitute Letter of Credit in Section 15.2.

SECTION 15.5 Draws on the Letter of Credit

The Trustee shall make draws on the Letter of Credit as follows:

(a) Draws to Pay Debt Service. The Trustee shall draw on the Letter of Credit in accordance with its terms for payment by the Bank to the Trustee on each Bond Payment Date of an amount equal to Debt Service due on such Bond Payment Date with respect to Bonds supported by the Letter of Credit other than Obligor Bonds or Bank Bonds. Such draws shall be made without regard to the availability of funds for the payment of such Debt Service from any

other source. Any money so drawn under the Letter of Credit shall be held in a separate account within the Debt Service Fund and shall not be commingled with any other money in the Debt Service Fund. The money so drawn shall be used only to pay Debt Service on Bonds supported by the Letter of Credit other than Obligor Bonds and Bank Bonds.

(b) Acceleration and Draw to Pay Debt Service. If an acceleration occurs pursuant to Section 11.2, the Trustee shall immediately draw under the Letter of Credit to pay Debt Service on Bonds supported by the Letter of Credit other than Obligor Bonds and Bank Bonds. Any money so drawn shall be held in a separate account within the Debt Service Fund and shall not be commingled with any other money in the Debt Service Fund. The money so drawn shall be used only to pay Debt Service on Bonds supported by the Letter of Credit other than Obligor Bonds and Bank Bonds.

(c) Draws to Pay the Purchase Price of Tendered Bonds. Not less than one hour before the latest time that a draw may be made on the Letter of Credit for payment of funds by the Bank to the Trustee on a Tender Date, the Trustee shall determine the amount of Remarketing Proceeds already on deposit in the Bond Purchase Fund. After such determination, the Trustee shall draw on the Letter of Credit for payment by the Bank to the Trustee on the Tender Date of the amount (if any) by which (1) the Purchase Price due on such Tender Date with respect to Tendered Bonds supported by the Letter of Credit other than Obligor Bonds and Bank Bonds exceeds (2) Remarketing Proceeds with respect to such Bonds already on deposit in the Bond Purchase Fund. Any money so drawn under the Letter of Credit shall be held in a separate account within the Bond Purchase Fund and shall not be commingled with any other money in the Bond Purchase Fund. The money so drawn shall be used only to pay the Purchase Price of Tendered Bonds supported by the Letter of Credit other than Obligor Bonds and Bank Bonds.

SECTION 15.6 Disposition of Bank Bonds

Bank Bonds shall be held by the Trustee for the benefit of the Bank, or shall be delivered as directed by the Bank, as provided in Section 6.6(e)(3). Upon reinstatement of the Letter of Credit with respect to the draw made to purchase any Bank Bond, such Bond shall no longer be considered a Bank Bond for purposes of this Indenture and such Bond shall be registered and delivered as follows:

(a) If such Bond has been remarketed by the Remarketing Agent, it shall be registered and delivered as directed by the Remarketing Agent.

(b) If such Bond has not been remarketed, it shall be registered and delivered as directed by the Corporation.

SECTION 15.7 Rights of Bank with Respect to Defaults and Remedies

If no Bank Default exists, the Bank shall have the following rights with respect to defaults and remedies:

(a) If an Indenture Default exists, without relieving the Board from the responsibility for performance and observance of the agreements and covenants required to be performed and observed by it hereunder, the Bank, on behalf of the Board, may perform any such agreement or covenant.

(b) The Bank shall have the right to control the exercise of available remedies under this Indenture or the granting of any waiver under this Indenture, to the extent provided in Section

11.2(d)(2); provided, however, that the Bank may not prevent the Trustee from making a draw on the Letter of Credit pursuant to Section 15.5.

SECTION 15.8 Subrogation Rights of Bank

(a) The Bank shall be subrogated to all rights possessed by the Holders of the Bonds in respect of which Debt Service shall have been paid with funds provided by the Bank pursuant to the Letter of Credit. Such subrogation rights shall be subordinate in right of payment to the rights of all other Holders of Bonds, and, to that end, the Bank shall be precluded from exercising or enforcing any subrogation rights under this Indenture unless and until all Bonds supported by the Bank’s Letter of Credit that are owned by any person other than the Bank shall have been Fully Paid. After all such Bonds owned by any person other than the Bank have been Fully Paid, any reference herein to the Holders of such Bonds shall mean the Bank to the extent of its subrogation rights resulting from payments made pursuant to the Letter of Credit. If Debt Service on any Bond is paid with funds provided by the Bank pursuant to the Letter of Credit, then, insofar as the subrogation rights of the Bank are concerned, such Bond shall be deemed to be in default and Outstanding with respect to such Debt Service until all amounts paid in respect thereof under the Letter of Credit shall have been repaid to the Bank, and, after all Bonds supported by the Bank’s Letter of Credit that are owned by persons other than the Bank have been Fully Paid, the Bank may exercise all rights which it would have under the Indenture as the Holder of such Bond then in default as to the payment of such Debt Service.

(b) The Bank may exercise all its subrogation rights under the Indenture in respect of any Bonds supported by its Letter of Credit without the necessity of possessing any of such Bonds or producing the same in any trial or other proceeding related to the enforcement of its rights in respect thereof. Nevertheless, in order to evidence the subrogation rights acquired in respect of any Debt Service on which was paid with funds provided pursuant to the Letter of Credit, the Bank may require the Trustee to transfer to it all Bonds surrendered for payment with funds provided pursuant to the Letter of Credit or to issue to it new Bonds of like tenor with those so surrendered. The subrogation rights granted to the Bank in this Indenture are not intended to be exclusive of any other remedy or remedies available to the Bank, and such subrogation rights shall be cumulative and shall be in addition to (1) every other remedy given hereunder, under a Bank Reimbursement Agreement, a Bank Security Document or any other instrument or agreement with respect to the reimbursement of money paid by the Bank pursuant to the Letter of Credit, and (2) every other remedy now or hereafter existing at law or in equity or by statute.

(c) Any rights of the Bank under this Section shall be in addition to any rights of the Bank under any other section of this Indenture or the related financing documents.

SECTION 15.9 Amendment of Bond Documents

If no Bank Default exists, (a) no amendment may be made to the Bond Documents without the consent of the Bank and (b) the Bank may, on behalf of all Holders of Bonds that are supported by the Bank’s Letter of Credit (and without notice to or consent of such Holders), consent to any amendment of the Bond Documents other than an amendment described in Section 13.3.

SECTION 15.10 Removal of Trustee or Remarketing Agent and Appointment of Successor

If no Bank Default exists, no portion of the Indenture Funds or Trust Estate may be distributed to the Corporation pursuant to Section 9.2 or Section 11.3 without consent of the Bank unless the Bank’s Letter of Credit has been cancelled and all indebtedness of the Corporation to the Bank has been fully paid.

SECTION 15.12 Trustee To Be Agent of Bank For Limited Purpose

The Trustee agrees that it shall serve as agent of the Bank for the limited purpose of taking possession of the money and investments on deposit in the Indenture Funds in order to perfect the security interest of the Bank in such money and investments granted by the documents executed by the Board in connection with the issuance of the Letter of Credit; provided, however, that the security interest of the Bank in such money and investments shall be subject and subordinate to the lien of the Indenture for the benefit of all Bonds (without preferences of one Bonds over another), and, until the Bonds have been Fully Paid, such money and investments shall be applied solely as provided in this Indenture.

SECTION 15.13 Exercise of Optional Redemption Rights

Notwithstanding any other provision of this Indenture, Bonds supported by a Letter of Credit may not be redeemed pursuant to any optional redemption rights granted pursuant to this Indenture unless (a) the Bank consents to such redemption or (b) the redemption price is deposited in the Debt Service Fund before the notice of redemption is given.

SECTION 15.14 Remarketing of Bonds

Notwithstanding the provisions of Section 6.6(a)(2), the Corporation may not direct the Remarketing Agent to cease remarketing of Bonds supported by a Letter of Credit without consent of the Bank.

SECTION 15.15 Benefits of Indenture for Bank

This Indenture shall also be for the benefit and security of the Bank, and the Bank shall have legal or equitable rights, remedies and claims to the extent provided herein.

SECTION 15.16 Direct Purchase Mode

There shall be no Letter of Credit in effect for Bonds in Direct Purchase Mode.

Miscellaneous

SECTION 17.1 Notices

(a) Any request, demand, authorization, direction, notice, consent, waiver or other document provided or permitted by this Indenture to be made upon, given or furnished to, or filed with, any of the Financing Participants must (except as otherwise expressly provided in this Indenture) be in writing and be delivered by one of the following methods: (1) by personal delivery, (2) by first-class, registered or certified mail, or (3) by facsimile transmission.

If this instrument permits any oral notice to the Trustee, such notice must be delivered or given to a corporate trust officer to be effective. The hand delivery address, mailing address and (if applicable) facsimile transmission number for receipt of notice or other documents by such parties are set forth in Exhibit 17.1(a).

Where this Indenture provides for notice in any manner, such notice may be waived in writing by the person entitled to receive such notice, either before or after the event, and such waiver shall be the equivalent of such notice. Waivers of notice by Bondholders shall be filed with the Trustee, but such filing shall not be a condition precedent to the validity of any action taken in reliance upon such waiver.

or so much thereof as has been advanced under the Draw-Down Provisions herein, on the last day of the Direct Purchase Rate Period specified above and to pay interest hereon from the date of initial delivery of this bond, or the most recent date to which interest has been paid or duly provided for, until the principal hereof shall become due and payable at the Direct Purchase Rate, the Weekly Rate or the Term Rate, as hereinafter provided; provided, however, that all such payments shall be limited obligations of the Board payable solely from the sources hereinafter identified.

Interest at the Weekly Rate and interest at the Term Rate for any Term Rate Period of 1 year or less shall be computed on the basis of a 365 or 366-day year, as the case may be, for the actual number of days elapsed. Interest at the Term Rate for any Term Rate Period of more than 1 year shall be computed on the basis of a 360-day year with 12 months of 30 days each.

If not otherwise specified in the Indenture or a Direct Purchaser Security Document, the Post-Default Rate shall be a rate per annum equal to the rate of interest last applicable to this bond when such overdue principal or interest became delinquent. Upon a Determination of Taxability, the bonds shall bear interest at the Taxable Rate, effective on the date determined by the Internal Revenue Service as the date on which the interest became includible in gross income of the Holder.

Interest on this bond shall be payable in arrears on the following dates:

(1) with respect to interest on any bond payable at the Weekly Rate, (A) on the first Business Day of each month and (B) on the effective date of Conversion of such bond from the Weekly Rate Mode to another Interest Rate Mode;

(2) with respect to interest on any bond payable at a Term Rate for a Term Rate Period of 270 days or less, on the last day of the Term Rate Period;

(3) with respect to interest on any bond payable at the Term Rate for any Term Rate Period of more than 270 days, (A) on the first Business Day of the calendar months during which there occurs the six-month anniversary and the one-year anniversary of the Conversion to such Term Rate Period and semi-annually on the first Business Day of each such month thereafter, and (B) on the last day of the Term Rate Period; and

(4) with respect to any bond payable at the Direct Purchase Rate, (A) on the first Business Day of each month (B) on the Business Day immediately succeeding the last day of each Direct Purchase Rate Period, and (C) the effective date of Conversion of such bond from the Direct Purchase Mode to another Interest Rate Mode.

The interest so payable, and punctually paid or duly provided for, on any Interest Payment Date will, as provided in the Indenture hereinafter referred to, be paid to the person in whose name this bond is registered at the close of business on the Regular Record Date for such interest, which shall be (a) with respect to any Weekly Rate Interest Payment Date, the day immediately prior to such Interest Payment Date, (b) with respect to any Term Rate Interest Payment Date for a Term Rate Period of 1 year or less, the day immediately prior to such Interest Payment Date, (c) with respect to any Term Rate Interest Payment Date for a Term Rate Period of more than 1 year, the 15th day (whether or not a Business Day) of the month next preceding such Interest Payment Date, and (d) with respect to any Direct Purchase Interest Payment Date, the day immediately prior to such Interest Payment Date. Any such interest not so

Exhibit A, Page 2 of 14

punctually paid or duly provided for shall forthwith cease to be payable to the registered Holder on such Regular Record Date, and shall be paid to the person in whose name this 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 of such Special Record Date being given to Holders of the bonds not less than 10 days prior to such Special Record Date.

Payment of Debt Service on this bond shall be made by the applicable method specified in the Indenture. All such payments shall be made in such coin or currency of the United States of America as at the time of payment is legal tender for the payment of public and private debts.

This bond is one of a duly authorized issue of bonds of the Board, aggregating $41,000,000 in principal amount, designated “Recovery Zone Facility Revenue Bonds (Olin Corporation Project), Series 2010” (the “Bonds”) and issued under and pursuant to a Trust Indenture dated December 27, 2010 (the “Indenture”), between the Board and U.S. Bank, National Association, a national banking association (in such capacity, the “Trustee”, which term includes any successor trustee under the Indenture). Capitalized terms not otherwise defined herein shall have the meaning assigned in the Indenture.

The bonds are being issued to provide financing for the benefit of Olin Corporation, a Virginia Corporation (“the Corporation”). Pursuant to a Loan Agreement dated December 27, 2010 (the “Loan Agreement”) between the Board and the Corporation, the proceeds of the bonds have been loaned to the Corporation and the Corporation has agreed to make loan payments at times and in amounts sufficient to pay all Debt Service on the bonds, including without limitation the Purchase Price of bonds tendered for purchase pursuant to the Optional or Mandatory Tender provisions of the Indenture. The loan repayment obligation of the Corporation is evidenced by a promissory note (the “Note”) delivered by the Corporation pursuant to the Loan Agreement.

The bonds and all other payment obligations under the Indenture are limited obligations of the Board payable solely out of the Trust Estate, including payments by the Corporation pursuant to the Loan Agreement and the Note. THIS BOND SHALL NOT BE DEEMED TO CONSTITUTE A DEBT OR LIABILITY OF THE STATE OF TENNESSEE OR ANY POLITICAL SUBDIVISION THEREOF, INCLUDING BRADLEY COUNTY, THE CITY OF CLEVELAND OR THE BOARD, OR A PLEDGE OF THE FULL FAITH AND CREDIT OF THE STATE OR ANY POLITICAL SUBDIVISION INCLUDING BRADLEY COUNTY OR THE CITY OF CLEVELAND. The issuance of this bond shall not directly, indirectly or contingently obligate the State of Tennessee or any political subdivision thereof, including Bradley County and the City of Cleveland, to levy or to pledge any form of taxation whatever therefor and shall not obligate any political subdivision, including Bradley County, the City of Cleveland or the Board to make any appropriation for its payment. THE ISSUER HAS NO TAXING AUTHORITY.

Copies of the Bond Documents are on file at the Office of the Trustee, and reference is hereby made to such instruments for a description of the properties pledged and assigned, the nature and extent of the security, the respective rights thereunder of the Holders of the bonds and the Financing Participants, and the terms upon which the bonds are, and are to be, authenticated and delivered.

A Remarketing Agent will be appointed in accordance with the Indenture whenever the bonds are converted to Weekly Rate Mode or to any Term Rate Mode in which the Board reasonably determines (upon the direction of the Corporation) that a Remarketing Agent is required. The Remarketing Agent may be removed or may resign, and a successor may be appointed, subject to certain terms and conditions specified in the Indenture.

Draw-Down Provisions

Exhibit A, Page 3 of 14

The bonds were issued as a “draw-down loan” as described in § 1.150-1(c)(4) of the Regulations. On each date during the Draw-Down Period on which the Trustee receives from the Purchaser Agent funds for deposit into the Costs of Issuance Fund or the Acquisition Fund in accordance with Section 6.8 of the Indenture, the aggregate amount of payments or deposits on that date shall constitute an Advance under the Indenture. Each Advance will increase the Outstanding Principal Amount of this bond, and each increase in the Outstanding Principal Amount of this bond as the result of additional Advances shall be recorded hereon by the Trustee (or if the bond is in Direct Purchase Mode, by the Purchaser Agent) where indicated in the table at the end of this bond under the heading “Outstanding Principal Amount of this Series 2010 bond”; provided, however, that failure of the Trustee (or Purchaser Agent) to record any Advance on this bond shall not in any way compromise, reduce or eliminate in any way the Board’s obligations under this Indenture with respect to the full Outstanding Principal Amount of this bond, based upon the actual amount of proceeds delivered to the Trustee with respect thereto.

Notwithstanding any other provision in the Indenture or this bond, (1) the Outstanding Principal Amount of the bonds may not exceed the aggregate amount of $41,000,000, and (2) no additional Advances may be made after the expiration of the Draw-Down Period. If less than $41,000,000 of aggregate Advances have been made under the bonds when the Draw-Down Period expires, after giving effect to any extensions thereof, the bonds shall be Outstanding at that time in an aggregate principal amount equal to their Outstanding Principal Amount (as defined in the Indenture), computed using the last day of the Draw-Down Period as the determination date, and no further Advances shall be made under the Indenture after such date.

Interest Rates

This bond shall bear interest at the Direct Purchase Rate, the Weekly Rate or the Term Rate, as described below. All bonds must be in the same Interest Rate Mode at the same time, and if in Direct Purchase Mode, must be in the same Direct Purchase Rate Period. The Trustee shall specify on each bond certificate, in the space provided, which Interest Rate Mode is in effect with respect to such bond.

All bonds shall initially be issued in the Direct Purchase Mode and shall bear interest at a Direct Purchase Variable Rate.

Whenever the bonds are converted to Term Rate Mode, the Trustee shall specify on the certificate for such bond the Term Rate and the beginning and end of the Term Rate Period. Whenever the bonds are converted from another Interest Rate Mode to a Direct Purchase Mode or from one Direct Purchase Mode Period to another Direct Purchase Mode Period, the Purchaser Agent shall notify the Trustee in writing of the beginning and end of the Direct Purchase Rate Period, and the Trustee shall specify such dates on the certificate for such bond when authenticated.

Weekly Rate

The Weekly Rate shall be a fluctuating rate per annum determined periodically by the Remarketing Agent. The Weekly Rate shall be determined on the date of Conversion of the bonds to the Weekly Rate Mode and on the last Business Day before each Thursday. Interest accrual at the Weekly Rate so determined shall begin on (and shall include) (A) the date of determination, if such date is a Conversion Date, or (B) the Thursday following the date of determination, and shall end on (but shall not include) the next Thursday (or, if sooner, a Conversion Date); provided, however, that if the Remarketing Agent fails to determine the Weekly Rate on any such determination date, the Alternate Rate Index specified by the Indenture shall be deemed to be the rate determined.

The Weekly Rate with respect to the bonds shall be determined by the Remarketing Agent and shall be the lowest interest rate that would, in the opinion of the Remarketing Agent, result in the market

Exhibit A, Page 4 of 14

value of such bonds being 100% of the principal amount thereof on the date of such determination, taking into account relevant market conditions and credit rating factors as they exist on such date; provided, however, that the Weekly Rate may never exceed the Cap Rate.

Upon the request of any Bondholder, the Trustee shall confirm (by telephone and in writing, if so requested) the Weekly Rate then in effect.

Term Rate and Term Rate Periods

The Term Rate shall be a fixed rate per annum determined by the Remarketing Agent for a Term Rate Period specified by the Board in the notice of conversion of the bonds to the Term Rate Mode. Each Term Rate Period may be for any period of 30 or more days, subject to the terms and conditions of the Indenture.

Interest accrued at the Term Rate for any Term Rate Period shall begin on (and shall include) the first day of the Term Rate Period and shall end on (but shall not include) the last day of the Term Rate Period.

Not later than the last Business Day prior to the date proposed for conversion of the bonds to the Term Rate Mode, the Remarketing Agent shall determine the interest rate for the Term Rate Period, which shall be the lowest interest rate that would, in the opinion of the Remarketing Agent, result in the market value of such bonds being 100% of the principal amount thereof on the date of such determination, taking into account relevant market conditions and credit rating factors as exist on such date, and assuming that the Term Rate Period began on such date; provided, however, that the Term Rate may not exceed the Cap Rate.

Direct Purchase Rate and Direct Purchase Rate Periods

The Direct Purchase Rate shall be a rate per annum set forth in the Direct Purchase Agreement applicable to such bond, subject to the following terms and conditions:

(1) In connection with the Conversion of the bonds to a Direct Purchase Mode, or the affirmative establishment of a new Direct Purchase Rate Period subsequent to an expiring Direct Purchase Rate Period, the duration of each Direct Purchase Rate Period shall be no less than one hundred eighty (180) days, shall begin on the Conversion Date or the Business Day immediately succeeding the last day of the expiring Direct Purchase Rate Period, and shall end on a day immediately preceding a Direct Purchase Interest Payment Date. The specific dates on which a Direct Purchase Rate Period begins and ends with respect to each bond in Direct Purchase Mode shall be specified in such bond, as authenticated and delivered under Section 6.1(f) of the Indenture.

(A) A Direct Purchase Fixed Rate shall be a fixed rate of interest effective for the duration of such Direct Purchase Rate Period set forth in the Direct Purchase Agreement and certified to by the Purchasers as the lowest fixed rate of interest that would permit the bonds to be sold at par, plus accrued interest, on the Conversion Date, in no event to exceed the Cap Rate.

Exhibit A, Page 5 of 14

(B) A Direct Purchase Variable Rate shall be a variable rate of interest effective for the duration of such Direct Purchase Rate Period set forth in the Direct Purchase Agreement equal to the sum of LIBOR, plus the Designated Basis Points, which rate shall be certified to by the Purchaser as the lowest rate of interest that would permit the bonds to be sold at par, plus accrued interest, on the Conversion Date, in no event to exceed the Cap Rate.

The specific Direct Purchase Fixed Rate or Direct Purchase Variable Rate applicable for each Direct Purchase Rate Period shall be specified on the bond authenticated and delivered with respect to such Direct Purchase Rate Period under Section 6.1(f) of the Indenture. Notwithstanding the foregoing, in no event shall any bond commence bearing interest at the new Direct Purchase Rate for a new Direct Purchase Rate Period unless and until a Favorable Tax Opinion has been delivered to the Purchaser Agent and the Corporation with respect to such change.

(3) In the event a Purchaser has not elected to tender its bonds on the Business Day immediately succeeding the Initial Direct Purchase Rate Period pursuant to Section 6.4(a) of the Indenture and the Corporation has not directed a Conversion of the Interest Rate Mode, the non-tendered bonds shall continue to bear interest at the Direct Purchase Rate then in effect for a Direct Purchase Rate Period of one year. Thereafter any time the bonds are in the Direct Purchase Rate Mode, in the event the Holder thereof has not elected to tender its bonds on the Business Day immediately succeeding such Direct Purchase Rate Period pursuant to Section 6.4(a) of the Indenture and the Corporation has not directed a Conversion of the Interest Rate Mode, the bonds shall continue to bear interest at the Direct Purchase Rate then in effect for successive one year Direct Purchase Rate Periods.

Conversion of Interest Rate Modes

The Board may effect a conversion of the Interest Rate Mode on the bonds from one Interest Rate Mode to another Interest Rate Mode or establish a new Term Rate Period upon the expiration of any existing Term Rate Period or establish one Direct Purchase Rate Period upon the expiration of an existing Direct Purchase Rate Period, subject to the terms and conditions contained in the Indenture. No such conversion is permitted during a Term Rate Period or during a Direct Purchase Rate Period. On any Conversion Date the bonds to be converted must be purchased pursuant to the Mandatory Tender provisions of the Indenture referred to below. If a notice of Mandatory Tender is given by the Trustee in connection with a proposed Conversion of a bond to a different Interest Rate Mode, such bond shall be subject to a Mandatory Tender on such date notwithstanding the revocation of the election to effect such Conversion or the failure to satisfy the conditions for such Conversion.

Optional Tender

The bonds are not subject to Optional Tender while in Term Rate Mode or Direct Purchase Mode, except on the Business Day immediately succeeding the last day of a Direct Purchase Rate Period.

The Holder of any bond in Weekly Rate Mode shall have the right to tender such bond to the Trustee for purchase in whole or in part on any Business Day, and the Holder of any bond in Direct Purchase Mode shall have the right to tender such bond to the Trustee for purchase, in whole but not in part, on the Business Day immediately succeeding the last day of any Direct Purchase Rate Period. The Purchase Price shall be 100% of the principal amount of the bond to be purchased plus accrued interest thereon to the Optional Tender Date. In order to exercise such option with respect to any bond, the Holder thereof must deliver notice thereof to the Trustee, as provided below, at least 7 days prior to the

Exhibit A, Page 6 of 14

proposed Optional Tender Date so long as the bonds are in Weekly Rate Mode, and at least 120 days prior to the proposed Optional Tender Date so long as the bonds are in Direct Purchase Mode.

Any such notice of Optional Tender must be duly executed by the Bondholder and must specify (a) the name of the registered Holder of the bond to be tendered for purchase, (b) the Optional Tender Date, (c) the certificate number and principal amount of such bond, and (d) the principal amount of such bond to be purchased (if the bonds are in Weekly Rate Mode and such amount is less than the entire principal amount, both the amount to be purchased and the amount remaining must be in an Authorized Denomination). A form of the Optional Tender Notice may be obtained from the Trustee upon request.

If any notice of Optional Tender specifies an Optional Tender Date that is not a Business Day, then such notice shall be deemed to specify the next following Business Day as the Optional Tender Date. If the bonds are in Weekly Rate Mode, unless a notice of Optional Tender indicates that less than the entire principal amount of the bond is being tendered for purchase, the Holder will be deemed to have tendered the bond in its entire principal amount for purchase.

Upon delivery of a written notice of Optional Tender, the election to tender shall be irrevocable and binding upon such Holder and may not be withdrawn.

If a written notice of Optional Tender shall have been duly given with respect to any bond in Weekly Rate Mode, the Holder of such bond shall deliver such bond to the Office of the Trustee on the Optional Tender Date, together with all necessary endorsements for transfer. If the bonds are in Weekly Rate Mode, and only a portion of the bond is to be purchased (as a result of the exercise of the Optional Tender right only with respect to such portion), the Board shall execute and the Trustee shall authenticate and deliver to the Holder of such bond, without service charge, a new bond or bonds of the same Maturity and interest rate and of any Authorized Denomination or Denominations as requested by such Holder in aggregate principal amount equal to and in exchange for the unpurchased portion of the principal amount of the bond surrendered. Any bond (or portion thereof) that is to be so purchased but that is not so delivered to the Trustee (an “Unsurrendered Bond”) shall nevertheless be deemed to have been tendered by the Holder thereof on the Optional Tender Date.

If there has been irrevocably deposited in the bond Purchase Fund an amount sufficient to pay the Purchase Price of any Unsurrendered bond, such Unsurrendered bond shall be deemed to have been tendered for purchase and purchased from the Holder thereof on such Optional Tender Date and the Holder of such Unsurrendered bond shall not be entitled to receive interest on such Unsurrendered bond for any period on and after the Optional Tender Date.

Holders of bonds in Weekly Rate Mode may exercise Optional Tender rights notwithstanding the existence of an Indenture Default.

Mandatory Tender

The Holder of each bond shall be required to tender such bond to the Trustee for purchase on the following dates:

(1) Each Conversion Date with respect to the bonds.

(2) The last day of a Term Rate Period.

(3) 20 days after the Trustee receives written notice from the Bank (A) stating that an event of default, as therein defined, has occurred and is continuing under the Bank

Exhibit A, Page 7 of 14

Reimbursement Agreement and (B) directing the Trustee to effect a Mandatory Tender of the bonds.

(4) 5 days prior to the Stated Expiration Date of the Letter of Credit.

(5) For bonds in the Weekly Rate Mode, on any date proposed for delivery of a Substitute Letter of Credit.

(6) For bonds in Weekly Rate Mode, on any other date specified by the Corporation as a Mandatory Tender Date in a written notice delivered by the Corporation to the Trustee (with the prior written consent of the Bank) at least 30 days prior to the specified Mandatory Tender Date (or such number of days as shall be acceptable for the administrative convenience of the Trustee).

If any of such dates is not a Business Day, the Mandatory Tender Date shall be the next succeeding Business Day. The Purchase Price shall be 100% of the principal amount of the bond to be purchased plus accrued interest thereon to the Mandatory Tender Date.

No notice is required for a Mandatory Tender on the last day of a Term Rate Period. Notice of any other Mandatory Tender shall be given by the Trustee by registered or certified mail, mailed to the Holder of the affected bond at the address of such Holder appearing on the Bond Register not less than 15 days prior to the Mandatory Tender Date.

Any bond subject to Mandatory Tender shall be tendered by the Holder thereof for purchase on the Mandatory Tender Date, by delivering such bond to the Office of the Trustee, together with all necessary endorsements for transfer. Any bond that is to be so purchased but that is not so delivered to the Trustee on the Mandatory Tender Date (an “Unsurrendered Bond”) shall nevertheless be deemed to have been tendered for purchase by the Holder thereof on the Mandatory Tender Date.

If there has been irrevocably deposited in the Bond Purchase Fund an amount sufficient to pay the Purchase Price of any Unsurrendered Bond, such Unsurrendered Bond shall be deemed to be tendered for purchase and purchased from the Holder thereof on such Mandatory Tender Date and the Holder of such Unsurrendered Bond shall not be entitled to receive interest on such Unsurrendered Bond for any period on and after the relevant Mandatory Tender Date.

After notice of a Mandatory Tender has been given by the Trustee with respect to any bond, such bond shall be subject to Mandatory Tender notwithstanding the fact that the reasons for giving such notice cease to exist or are no longer applicable.

Redemption of Bonds

In the manner and with the effect provided in the Indenture, the bonds will be subject to redemption prior to Maturity as follows:

(1) On any date when a bond is in the Weekly Rate Mode and on any Conversion Date with respect to a bond, such bond may be redeemed in whole or in part at a redemption price equal to 100% of the principal amount to be redeemed plus accrued interest thereon to the date of redemption.

(2) During any Term Rate Period of 5 years or less with respect to the bonds, such bonds shall not be subject to optional redemption. During any Term Rate Period of more than 5 years with respect to the bonds, such bond may be redeemed in whole or in part on or after the

Exhibit A, Page 8 of 14

First Optional Call Date (as defined below) at a redemption price equal to 100% of the principal amount to be redeemed plus accrued interest thereon to the date of redemption plus a redemption premium (expressed as a percentage of principal amount redeemed) equal to whichever of the following shall be applicable: 2% if the date of redemption is on or after the First Optional Call Date but prior to the first anniversary of the First Optional Call Date; 1% if the date of redemption is on or after the first anniversary of the First Optional Call Date but prior to the second anniversary of the First Optional Call Date; and without premium if the date of redemption is on or after the second anniversary of the First Optional Call Date. For any Term Rate Period of more than 5 years but not more than 10 years, the First Optional Call Date shall be the fifth anniversary of the beginning of the Term Rate Period. For any Term Rate Period of more than 10 years but not more than 20 years, the First Optional Call Date shall be the anniversary of the beginning of the Term Rate Period that is on or immediately after the midpoint of such Term Rate Period. For any Term Rate Period of more than 20 years, the First Optional Call Date shall be the tenth anniversary of the beginning of the Term Rate Period.

(3) While the bonds are in the Direct Purchase Mode and bear interest at a Direct Purchase Variable Rate, the bonds shall be subject to optional redemption before maturity at the direction of the Corporation in whole or in part on any Direct Purchase Interest Payment Date at a redemption price of 100% of the principal amount thereof, plus accrued interest to the redemption date, and without premium. While the bonds are in the Direct Purchase Mode and bear interest at a Direct Purchase Fixed Rate, the bonds shall be subject to optional redemption before maturity at the direction of the Corporation in whole or in part on any Direct Purchase Interest Payment Date at a redemption price of 100% of the principal amount thereof, plus accrued interest to the redemption date, plus a premium equal to 5% of the outstanding principal amount of the bonds so redeemed in the first year following the Conversion Date on which such Direct Purchase Fixed Rate became effective, declining by 1% each year thereafter (but not below zero).

All (but not less than all) bonds may be redeemed at the option of the Board, at a redemption price equal to 100% of the principal amount to be redeemed plus accrued interest thereon to the redemption date, within 180 days after any of the following shall have occurred:

(B) the taking by eminent domain of all or substantially all the Bond-Financed Facilities or of any part, use or control of the Bond-Financed Facilities that, in the opinion of the Corporation, results in the Corporation being thereby prevented from carrying on its normal operations at the Bond-Financed Facilities for a period of not less than 4 months; or

Exhibit A, Page 9 of 14

bonds shall be selected for redemption as follows:

(1) Except as otherwise provided in the specific redemption provisions for a bond or in paragraph (3) below, if less than all bonds Outstanding are to be redeemed pursuant to the applicable optional redemption provisions, the principal amount of bonds of each Maturity to be redeemed may be specified by the Board by written notice to the Trustee, or, in the absence of timely receipt by the Trustee of such notice, shall be selected by the Trustee by lot or by such other method as the Trustee shall deem fair and appropriate; provided, however, that the principal amount of bonds of each Maturity to be redeemed must be in an Authorized Denomination.

(2) Except as otherwise provided in the specific redemption provisions for a bond or in paragraph (3) below, if less than all bonds with the same Maturity are to be redeemed, the particular bonds of such Maturity to be redeemed shall be selected by the Trustee by lot or by such other method as the Trustee shall deem fair and appropriate and which may provide for the selection for redemption of portions (in Authorized Denominations) of the principal of the bonds of such Maturity of a denomination larger than the smallest Authorized Denomination.

(3) Notwithstanding any other provision of the Indenture, (A) Bank Bonds eligible for redemption must be selected for redemption before any other eligible bonds are selected for redemption, and (B) with respect to bonds in Direct Purchase Mode, the election to exercise any right of optional redemption shall be evidenced by notice to the Trustee and the Purchaser Agent from an Authorized Corporation Representative, which notice must be received by the Trustee and the Purchaser Agent at least 10 days prior to the date fixed for redemption (unless a shorter notice is acceptable to the Trustee), and must contain the information specified in Section 5.3 of the Indenture, and if less than all such bonds Outstanding are to be redeemed, the principal amount of bonds of each Maturity to be redeemed may be specified by the Corporation and the Holder of such bonds by notice delivered to the Trustee not less than 10 days before the date fixed for redemption (unless a shorter notice is acceptable to the Trustee), or in the absence of timely receipt by the Trustee of such notice, shall be selected by the Trustee by lot or by such other method as the Trustee shall deem fair and appropriate; provided, however, that the principal amount of bonds of each Maturity to be redeemed may not be larger than the principal amount of bonds of such Maturity then eligible for redemption and may not be smaller than the smallest Authorized Denomination.

Upon any partial redemption of any bond the same shall, except as otherwise permitted by the Indenture, be surrendered in exchange for one or more new bonds of the same Maturity and in authorized form for the unredeemed portion of principal. bonds (or portions thereof as aforesaid) for whose redemption and payment provision is made in accordance with the Indenture shall thereupon cease to be entitled to the lien of the Indenture and shall cease to bear interest from and after the date fixed for redemption.

Any redemption shall be made upon at least 30 days’ notice (10 days for bonds in Direct Purchase Mode) in the manner and upon the terms and conditions provided in the Indenture.

If an “Indenture Default”, as defined in the Indenture, shall occur, the principal of all bonds then Outstanding may become or be declared due and payable in the manner and with the effect provided in the Indenture.

The Indenture permits the amendment of the Bond Documents and waivers of past defaults under such instruments and the consequences of such defaults, in certain circumstances without consent of Bondholders and in other circumstances with the consent of all Bondholders or a specified percentage of Bondholders. Any such consent or waiver by the Holder of this bond shall be conclusive and binding

Exhibit A, Page 10 of 14

upon such Holder and upon all future Holders of this bond and of any bond issued in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this bond.

The Holder of this bond shall have no right to enforce the provisions of the Indenture, or to institute any action to enforce the covenants therein, or to take any action with respect to any default thereunder, or to institute, appear in or defend any suit or other proceeding with respect thereto, except as provided in the Indenture.

As provided in the Indenture and subject to certain limitations therein set forth, this bond is transferable on the Bond Register maintained at the Office of the Trustee, upon surrender of this bond for transfer at such office, together with all necessary endorsements for transfer, and thereupon one or more new bonds of the same Maturity, of any Authorized Denominations and for a like aggregate principal amount, will be issued to the designated transferee or transferees.

As provided in the Indenture and subject to certain limitations therein set forth, the bonds are exchangeable for other bonds of the same Maturity, of any Authorized Denominations and of a like aggregate principal amount, as requested by the Holder surrendering the same.

No service charge shall be made for any transfer or exchange hereinbefore referred to, but the Board may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.

The Board and 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, whether or not this bond is overdue, and neither the Board nor the Trustee shall be affected by notice to the contrary.

No covenant or agreement contained in this bond or the Indenture shall be deemed to be a covenant or agreement of any officer, agent or employee of the Board, and neither any member of the governing body of the Board nor any officer executing this bond shall be liable personally on this bond or be subject to any personal liability or accountability by reason of the issuance of this bond.

It is hereby certified, recited and declared that all acts, conditions and things required to exist, happen and be performed precedent to and in the execution and delivery of the Indenture and issuance of this bond do exist, have happened and have been performed in due time, form and manner as required by law.

Unless the certificate of authentication hereon has been executed by the Trustee by manual signature, this bond shall not be entitled to any benefit under the Indenture or be valid or obligatory for any purpose.

THIS BOND MAY BE TRANSFERRED IN WHOLE, BUT NOT IN PART, ONLY IN ACCORDANCE WITH THAT CERTAIN TRUST INDENTURE DATED DECEMBER 27, 2010, BETWEEN THE ISSUER AND THE BOARD AND MAY BE TRANSFERRED ONLY TO QUALIFIED INSTITUTIONAL BUYERS THAT PURCHASE COMMERCIAL PROMISSORY NOTES IN THE ORDINARY COURSE OF BUSINESS.
