The Contract is revised as follows:    1) The following language is added to the DEFINITIONS of the Contract:     "BUFFER. The Buffer is an Index Adjustment Factor. The Buffer is the allowable decrease in  Index price before a negative Index Adjustment is credited to the Index Account Option value at  the end of the Index Account Option term, expressed as a percentage. The Interim Value uses a  prorated Buffer based on the elapsed portion of the Index Account Option term. If the  Performance Boost with Buffer Crediting Method is elected, the declared Buffer percentage(s)  applicable on the Issue Date will be reflected in the transaction confirmation statement sent to  You.    PERFORMANCE BOOST CAP RATE (PBCR). The PBCR is an Index Adjustment Factor that  represents the maximum Index Adjustment that will be credited to the Index Account Option at  the end of each Index Account Option term, expressed as a percentage. This limits the positive  Index Adjustment that may be credited to the Index Account Option. The PBCR is declared at  the beginning of the Index Account Option term. The Interim Value uses a prorated PBCR  based on the elapsed portion of the Index Account Option term. If the Performance Boost with  Buffer Crediting Method is elected, the declared PBCR(s) applicable on the Issue Date will be  reflected in the transaction confirmation statement sent to You.     PERFORMANCE BOOST RATE (PBR). The PBR is an Index Adjustment Factor that  represents the amount that will be added to the Index Return, expressed as a percentage, that  will increase the value of the Index Adjustment credited to the Index Account Option value (up to  the stated Performance Boost Cap Rate) at the end of each Index Account Option Term, if the  performance criteria are met. The PBR will be equal to the Buffer percentage. The PBR is  declared at the beginning of the Index Account Option term. The Interim Value uses a prorated  PBR based on the elapsed portion of the Index Account Option term. If the Performance Boost  with Buffer Crediting Method is elected, the declared PBR(s) applicable on the Issue Date will  be reflected in the transaction confirmation statement sent to You.     ENDORSEMENT  





 






  7790-PB 2  PERFORMANCE BOOST WITH BUFFER CREDITING METHOD. The Performance Boost with  Buffer Crediting Method credits an Index Adjustment to the Index Account Option value at the  end of the Index Account Option term based on the following Index performance criteria. When  the Index performance is positive, it will result in a positive Index Adjustment equal to the  positive Index performance plus the PBR percentage up to a maximum of the PBCR Rate.  When the Index performance is zero or negative, but not in excess of the Buffer, it will result in  an Index Adjustment equal to the negative Index performance plus the PBR percentage up to a  maximum of the PBCR. Negative Index performance in excess of the Buffer percentage will  result in a negative Index Adjustment."    2) The following language is added to the CONTRACT OPTION PROVISIONS of the Contract.    "Index-linked returns do not include the portion of returns generated by the underlying Index that  come from dividends. The Index Adjustment Factors used in determining the Index Adjustment  are not guaranteed and can be changed by the Company on any Index Account Option Term  Anniversary, subject to the guarantees in the Supplemental Contract Data pages. Any such  changes can affect the Index Adjustment.    The Index Adjustment is determined as follows:    Performance Boost with Buffer    Index Adjustment = IF (Pe– Pb) / Pb >= -B THEN = IAOV x MINIMUM [PBCR, (Pe– Pb) / Pb + PBR]  = IF (Pe– Pb) / Pb < -B THEN = IAOV x [(Pe– Pb) / Pb+ B]    During the Index Account Option term:     The Index Account Option value will be equal to the Interim Value. The Index Adjustment to the  Interim Value will be calculated according to the preceding formula using the following  definitions:   Pb = the Index price at the beginning of the Index Account Option term.   Pe = the Index price on the date the Interim Value is calculated.   IAOV = the greater of the Index Account Option value at the beginning of the Index  Account Option term, reduced for any Intra-Term Performance Locks and gross  partial withdrawals in the same proportion that the Interim Value was reduced on  the date of the Intra-Term Performance Lock or withdrawal, or zero.   PBCR =        ×   × the PBCR declared at the beginning of the Index   Account Option term.   B =        ×   × the Buffer declared at the beginning of the Index   Account Option term.   PBR =        ×   × the PBR declared at the beginning of the Index   Account Option term.    The Index Adjustment will be calculated by the Company based on the closing price of the Index  on the date the Interim Value is calculated.

Pe = the Index price on the Index Account Option Term Anniversary.   IAOV = the greater of the Index Account Option value at the beginning of the Index  Account Option term, reduced for any Intra-Term Performance Locks and gross  partial withdrawals in the same proportion that the Interim Value was reduced on  the date of the Intra-Term Performance Lock or withdrawal, or zero.
