ARTICLE SECOND Securities of the Third Series SECTION 2.01. Description of Series. There shall be a series of Securities designated '8.137% Series due July 31, 2022" (herein sometimes referred to as the "Securities of the Third Series"), each of which shall also bear the descriptive title "First Mortgage Bond", and the form thereof, which shall be established in an Officer's Certificate as provided in the Indenture, shall contain suitable provisions with respect to the matters hereinafter in this Article specified. The aggregate principal amount of Securities of the Third Series which may be authenticated and delivered under the Indenture is limited to Ten Million Dollars ($10,000,000.00), except as provided in Sections 205 and 206 -3- of the Original Indenture. Securities of the Third Series shall mature on July 31, 2022 and shall be issued as fully registered Securities in denominations of One Thousand Dollars and, at the option of the Company, in any integral multiple or multiples thereof (the exercise of such option to be evidenced by the execution and delivery thereof); they shall bear interest at the rate of 8.137% per annum, payable on July 3 1, 1997 for the period from March 31, 1997 to July 31, 1997, and semi-annually on January 31 and July 31 of each year thereafter until Maturity; the principal of, premium, if any, and interest on each said Security to be payable at the office or agency of the Company in Apopka, Florida, in such coin or currency of the United States of America as at the time of payment is legal tender for public and private debts. Securities of the Third Series shall be dated as in the Indenture provided. Interest on the Securities of the Third Series shall be computed on the actual number of days elapsed on the basis of a year consisting of 360 days. If the Company shall default in the payment of the principal of, or premium or interest on, any Security of the Third Series, the Company shall pay to the Holder of such Security such overdue principal, premium or interest, together with interest on such overdue principal and (to the extent permitted by law) on such overdue premium or interest at the rate borne by such Security immediately prior to such default plus two per centum (2%) per annum. The Regular Record Date referred to in Section 207 of the Indenture for the payment of the interest on the Securities of the Third Series payable on any Interest Payment Date shall be the first Business Day next preceding such Interest Payment Date. The Company shall be exempt from filing the Cash Flow Certificate provided in Section 301(d) of the Original Indenture with respect to the issuance of Securities of the Third Series. SECTION 2.02. Optional Redemption of Securities of the Third Series. (I) Securities of the Third Series shall be redeemable on any Business Day, at the option of the Company, in whole or in part in accordance with Section 903 of the Original Indenture from time to time, prior to maturity, upon notice delivered to each Holder at its last address appearing on the Security Register not less than one Business Day prior to the date fixed for redemption, at a Redemption Price ("Third Series General Redemption Price") (expressed as a percentage of the principal amount of the Securities to be redeemed) equal to the sum of (i) one hundred per centum (100%) plus (ii) a "Third Series Prepayment Surcharge" calculated as hereinafter provided, in each case together with accrued interest to the date fixed for redemption. For purposes of calculating the Third Series General Redemption Price, the Third Series Prepayment Surcharge shall be calculated as follows: (A) Determine the difference between: (1) eight and 137/1000 per centum (8.137%) minus (2) the Discount Rate, as hereinafter defined, as of the Redemption Date. (B) Add one half (1/2) of one per centum (1%) to such difference (such that the minimum result shall at all times be 1/2 of 1% if the redemption occurs prior to July 31, 2000; thereafter, no amount shall be added in this step (B) provided that, in any event, the minimum result shall be at least zero). (C) Divide the result determined in (B) above by 2. (D) For each semi-annual period or portion thereof during which the principal amount redeemed was scheduled to have been Outstanding, multiply the amount described in (C) above by the portion of the principal amount redeemed that was scheduled to have been Outstanding on the last day of such semi-annual period (such that there is a calculation for each semi-annual -4- period during which the principal amount redeemed was scheduled to have been Outstanding). (E) Determine the present value of each semi-annual calculation made under (D) above based upon the scheduled time that interest on the principal amount redeemed would have been payable and the Discount Rate as of the Redemption Date. (F) Add all of the calculations made under (E) above. The result shall be the Third Series Prepayment Surcharge. Unless otherwise agreed with a majority of the Holders of the Securities of the Third Series to be Outstanding after a redemption under this Section, the Securities redeemed under this Section may not be used as a credit for the redemption of Securities provided for in Section 2.03 of this Second Supplemental Indenture. (II) A notice containing the calculation of the Third Series General Redemption Price shall be prepared by the Company and delivered to the Trustee and the Holders of the Securities of the Third Series to be redeemed on the Business Day next preceding the Redemption Date. The calculation set forth in such notice shall be final unless the Holders of the Securities so redeemed notify the Company and the Trustee of an error in such calculations within 30 days after notice of such calculation. If it is determined that the Company has made an error in such calculation and the Company pays the difference to such Holders promptly after such determination, then the Company shall not be deemed to be in default under the Indenture by reason of late payment of such difference. (III) As pertains to Securities of the Third Series, the "Discount Rate" shall mean an interest rate determined by adding to the yield on treasury bonds having maturities equal to the weighted average life to maturity of the Securities to be redeemed, determined as necessary by interpolation of treasury bonds having the next longer and next shorter maturities ("Treasury Yield"), as reported on the "MMKS" Reuters monitor screen for the Business Day prior to the Redemption Date for such Securities, the following: (A) the estimated spread of Farm Credit Securities over the Treasury Yield for such day, as reported in a Farm Credit Funding Corporation Interest Rate Summary report, and (B) the estimated dealer concession, obtained by a polling of Farm Credit Funding Corporation dealers on the Business Day next preceding the Redemption Date, for issuing Farm Credit Securities having a weighted average life equal to the number of days between the Redemption Date and Maturity for Securities of the Third Series to be redeemed. In the event any fact required for such calculation is not available, the computation of Discount Rate shall be made on the basis of a reasonably equivalent method of determination. SECTION 2.03. Sinking Fund for Securities of the Third Series. So long as any Securities of the Third Series shall remain Outstanding, the Company shall redeem the principal thereof in accordance with the following schedule, commencing on July 31, 1997 and semi-annually on or before each January 31 and July 31 thereafter, through and including July 31, 2022: July 31, 1997 $ 61,241.65 January 31, 1998 $ 63,733.27 July 31, 1998 $ 66,326.25 January 31, 1999 $ 69,024.74 -5- July 31, 1999 $ 71,833.01 January 31, 2000 $ 74,755.54 July 31, 2000 $ 77,796.96 January 31, 2001 $ 80,962.13 July 31, 2001 $ 84,256.08 January 31, 2002 $ 87,684.04 July 31, 2002 $ 91,251.46 January 31, 2003 $ 94,964.03 July 31, 2003 $ 98,827.64 January 31, 2004 $102,848.44 July 31, 2004 $107,032.83 January 31, 2005 $111,387.46 July 31, 2005 $115,919.26 January 31, 2006 $120,635.44 July 31, 2006 $125,543.49 January 31, 2007 $130,651.23 July 31, 2007 $135,966.77 January 31, 2008 $141,498.58 July 31, 2008 $147,255.45 January 31, 2009 $153,246.54 July 31, 2009 $159,481.37 January 31, 2010 $165,969.87 July 31, 2010 $172,722.36 January 31, 2011 $179,749.56 July 31, 2011 $187,062.68 January 31, 2012 $194,673.32 July 31, 2012 $202,593.60 January 31, 2013 $210,836.13 July 31, 2013 $219,433.99 January 31, 2014 $228,340.85 July 31, 2014 $237,630.90 January 31, 2015 $247,298.91 July 31, 2015 $257,360.27 January 31, 2016 $267,830.97 July 31, 2016 $278,727.67 January 31, 2017 $290,067.71 July 31, 2017 $301,869.11 January 31, 2018 $314,150.66 July 31, 2018 $326,931.88 January 31, 2019 $340,233.10 July 31, 2019 $354,075.49 January 31, 2020 $368,481.05 July 31, 2020 $383,472.70 January 31, 2021 $399,074.28 July 31, 2021 $415,310.62 January 31, 2022 $432,207.53 July 31, 2022 $449,791.13 ARTICLE THIRD Additional Covenants for Third Series SECTION 3.01.
