$25,000.00 – $100,000.00	12.50%
$100,000.01 – $500,000.00	11.25%
$500,000.01 and greater	11.00%

2.Prepayment Fee.  If a Contract is prepaid for any reason, SBCC will be entitled to receive, in addition to the Repurchase Price for the Contract, a prepayment fee equal to the greater amount computed under the following schedules:

Schedule 1:

The prepayment fee will be equal to the Repurchase Price of the Contract multiplied by the applicable percentage determined below.

Prepayment Occurring During Months Following Date Contract Purchased	Prepayment Fee as Percentage of Repurchase Price.
Months 01-12	5%
Months 13-24	4%
Months 25-36	3%
Months 37-48	2%
Months 49-60	1%
Months 61 and thereafter	0%

Schedule 2[applicable only to dollar-denominated Contracts and International Contracts for which the Repurchase Price is determined on the basis of clause (i) (A) of paragraph 1(o) of the Letter Agreement]

The prepayment fee for any Contract shall be the difference between (a) the present value of the remaining Balance of Payment calculated using the Applicable Treasury Rate quoted most recently prior to the date such Contract is repurchased minus (b) the present value of such remaining Balance of Payment calculated using the Applicable Treasury Rate quoted

most recently prior to the date such Contract was purchased by SBCC, provided that in no event will the prepayment fee be less than 0.

The “Applicable Treasury Rate” will be the “This Week” rate quoted for “Treasury Constant Maturities” of the applicable maturity, as determined by the following chart, in Statistical Release H.15 (519) published by the Board of Governors of the Federal Reserve System.  In the event that the Board of Governors ceases publishing H.15 (519), the Applicable Treasury Rate, will be determined using a comparable index chosen by SBCC in good faith.

Contract Term in Months*	Applicable Maturity of Treasury Constant Maturities
18 or less	1-Year
more than 18 but 48 or less	2-Year
More than 48 but 72 or less	3-Year
More than 72 but 120 or less	5-Year

*Note: to determine the Applicable Treasury Rate for the date the Contract was purchased by SBCC, use the original term of the Contract.  To determine the Applicable Treasury Rate for the date the Contract is repurchased, use the number of whole months in the remaining term on the date of repurchase.

Agreed to this 25 day of March 1992.
