     Group Excess Spread Percentage (Item 16(a)) and the Series Excess Spread

     Charge Collections, Yield Collections, Additional Funds and Investment
     Income for any Class of this Series (see Item 3(e)), and (b) the sum of
     (i) the monthly interest for each Class of this Series (see Item 1), (ii)
     the monthly servicing fee for each Class of this Series (see Item 12(d)),
     (iii) the Investor Charge-Off Amount (see Item 8(c)), and (iv) the Credit
     Enhancement Fee (see Item 14(d)), in each case for this Distribution Date.
     The Series Excess Spread Percentage is equal to the Series Excess Spread,
     multiplied by twelve, divided by the Series Investor Interest for this
     Series.

(1)   For series in Group One, investors should refer only to the higher of the
      Group Excess Spread Percentage (Item 16(a)) and the Series Excess Spread
      Percentage (Item 16(c)) in assessing the current performance or the Trust
      and the Receivables.

(2)   Group Excess Spread is the sum of the Series Excess Spreads (as described
      below) for each series in the Group.  The Group Excess Spread Percentage
      is equal to the Group Excess Spread, multiplied by twelve, divided by the
      Series Investor Interests for each series in the Group.

(3)   Series Excess Spread is the difference between (a) the sum of Finance
      Charge Collections, Yield Collections, Additional Funds and Investment
      Income for any Class of this Series (see Item 3(e)), and (b) the sum of
      (i) the monthly interest for each Class of this Series (see Item 1), (ii)
      the monthly servicing fee for each Class of this Series (see Item 12(d)),
      (iii) the Investor Charge-Off Amount (see Item 8(c)), and (iv) the Credit
      Enhancement Fee (see Item 14(d)), in each case for this Distribution
      Date.  The Series Excess Spread Percentage is equal to the Series Excess
      Spread, multiplied by twelve, divided by the Series Investor Interest for
      this Series.

(4)   For purposes of allocations to investors, recoveries are treated as
      Finance Charge Collections and are included as such in Item 3 above.

 (1) For series in Group One, investors should refer only to the higher of the
     Group Excess Spread Percentage (Item 16(a)) and the Series Excess Spread
     Percentage (Item 16(c)) in assessing the current performance of the Trust
     and the Receivables.


 (2) Group Excess Spread is the sum of the Series Excess Spreads (as described
     below) for each series in the Group.  The Group Excess Spread Percentage
     is equal to the Group Excess Spread, multiplied by twelve, divided by the
     Series Investor Interests for each series in the Group.

 (3) Series Excess Spread is the difference between (a) the sum of Finance
     Charge Collections, Yield Collections, Additional Funds and Investment
     Income for any Class of this Series (see Item 3(e)), and (b) the sum of
     (i) the monthly interest for each Class of this Series (see Item 1), (ii)
     the monthly servicing fee for each Class of this Series (see Item 12(d)),
     (iii) the Investor Charge-Off Amount (see Item 8(c)), and (iv) the Credit
     Enhancement Fee (see Item 14(d)), in each case for this Distribution Date.
     The Series Excess Spread Percentage is equal to the Series Excess Spread,
     multiplied by twelve, divided by the Series Investor Interest for this
     Series.

 (4) For purposes of allocations to investors, recoveries are treated as
     Finance Charge Collections and are included as such in Item 3 above.

 (1) For series in Group One, investors should refer only to the higher of the
     Group Excess Spread Percentage (Item 16(a)) and the Series Excess Spread
     Percentage (Item 16(c)) in assessing the current performance of the Trust

     is equal to the Group Excess Spread, multiplied by twelve, divided by the
     Series Investor Interests for each series in the Group.

 (3) Series Excess Spread is the difference between (a) the sum of Finance
     Charge Collections, Yield Collections, Additional Funds and Investment
     Income for any Class of this Series (see Item 3(e)), and (b) the sum of
     (i) the monthly interest for each Class of this Series (see Item 1), (ii)
     the monthly servicing fee for each Class of this Series (see Item 12(d)),
     (iii) the Investor Charge-Off Amount (see Item 8(c)), and (iv) the Credit
     Enhancement Fee (see Item 14(d)), in each case for this Distribution Date.
     The Series Excess Spread Percentage is equal to the Series Excess Spread,
     multiplied by twelve, divided by the Series Investor Interest for this
     Series.

 (4) For purposes of allocations to investors, recoveries are treated as
     Finance Charge Collections and are included as such in Item 3 above.

 (1) For series in Group One, investors should refer only to the higher of the
     Group Excess Spread Percentage (Item 16(a)) and the Series Excess Spread
     Percentage (Item 16(c)) in assessing the current performance of the Trust
     and the Receivables.


 (2) Group Excess Spread is the sum of the Series Excess Spreads (as described
     below) for each series in the Group.  The Group Excess Spread Percentage
     is equal to the Group Excess Spread, multiplied by twelve, divided by the
     Series Investor Interests for each series in the Group.

 (3) Series Excess Spread is the difference between (a) the sum of Finance
     Charge Collections, Yield Collections, Additional Funds and Investment
     Income for any Class of this Series (see Item 3(e)), and (b) the sum of
     (i) the monthly interest for each Class of this Series (see Item 1), (ii)
     the monthly servicing fee for each Class of this Series (see Item 12(d)),
     (iii) the Investor Charge-Off Amount (see Item 8(c)), and (iv) the Credit
     Enhancement Fee (see Item 14(d)), in each case for this Distribution Date.
     The Series Excess Spread Percentage is equal to the Series Excess Spread,
     multiplied by twelve, divided by the Series Investor Interest for this
     Series.

 (4) For purposes of allocations to investors, recoveries are treated as
     Finance Charge Collections and are included as such in Item 3 above.

 (1) For series in Group One, investors should refer only to the higher of the
     Group Excess Spread Percentage (Item 16(a)) and the Series Excess Spread
     Percentage (Item 16(c)) in assessing the current performance of the Trust
     and the Receivables.

     is equal to the Group Excess Spread, multiplied by twelve, divided by the
     Series Investor Interests for each series in the Group.

 (3) Series Excess Spread is the difference between (a) the sum of Finance
     Charge Collections, Yield Collections, Additional Funds and Investment
     Income for any Class of this Series (see Item 3(e)), and (b) the sum of
     (i) the monthly interest for each Class of this Series (see Item 1), (ii)
     the monthly servicing fee for each Class of this Series (see Item 12(d)),
     (iii) the Investor Charge-Off Amount (see Item 8(c)), and (iv) the Credit
     Enhancement Fee (see Item 14(d)), in each case for this Distribution Date.
     The Series Excess Spread Percentage is equal to the Series Excess Spread,
     multiplied by twelve, divided by the Series Investor Interest for this
     Series.

 (4) For purposes of allocations to investors, recoveries are treated as
     Finance Charge Collections and are included as such in Item 3 above.

     Group Excess Spread Percentage (Item 16(a)) and the Series Excess Spread
     Percentage (Item 16(c)) in assessing the current performance of the Trust

     Charge Collections, Yield Collections, Additional Funds and Investment
     Income for any Class of this Series (see Item 3(e)), and (b) the sum of
     (i) the monthly interest for each Class of this Series (see Item 1), (ii)
     the monthly servicing fee for each Class of this Series (see Item 12(d)),
     (iii) the Investor Charge-Off Amount (see Item 8(c)), and (iv) the Credit
     Enhancement Fee (see Item 14(d)), in each case for this Distribution Date.
     The Series Excess Spread Percentage is equal to the Series Excess Spread,
     multiplied by twelve, divided by the Series Investor Interest for this
     Series.

 (4) For purposes of allocations to investors, recoveries are treated as
     Finance Charge Collections and are included as such in Item 3 above.

     Group Excess Spread Percentage (Item 16(a)) and the Series Excess Spread

     Charge Collections, Yield Collections, Additional Funds and Investment
     Income for any Class of this Series (see Item 3(e)), and (b) the sum of
     (i) the monthly interest for each Class of this Series (see Item 1), (ii)
     the monthly servicing fee for each Class of this Series (see Item 12(d)),
     (iii) the Investor Charge-Off Amount (see Item 8(c)), and (iv) the Credit
     Enhancement Fee (see Item 14(d)), in each case for this Distribution Date.
     The Series Excess Spread Percentage is equal to the Series Excess Spread,
     multiplied by twelve, divided by the Series Investor Interest for this
     Series.

     Finance Charge Collections and are included as such in Item 3 above.

     Group Excess Spread Percentage (Item 16(a)) and the Series Excess Spread

     Charge Collections, Yield Collections, Additional Funds and Investment
     Income for any Class of this Series (see Item 3(e)), and (b) the sum of

     (iii) the Investor Charge-Off Amount (see Item 8(c)), and (iv) the Credit
     Enhancement Fee (see Item 14(d)), in each case for this Distribution Date.
     The Series Excess Spread Percentage is equal to the Series Excess Spread,

     Group Excess Spread Percentage (Item 16(a)) and the Series Excess Spread

     Charge Collections, Yield Collections, Additional Funds and Investment
     Income for any Class of this Series (see Item 3(e)), and (b) the sum of
     (i) the monthly interest for each Class of this Series (see Item 1), (ii)
     the monthly servicing fee for each Class of this Series (see Item 12(d)),
     (iii) the Investor Charge-Off Amount (see Item 8(c)), and (iv) the Credit
     Enhancement Fee (see Item 14(d)), in each case for this Distribution Date.
     The Series Excess Spread Percentage is equal to the Series Excess Spread,

     Group Excess Spread Percentage (Item 16(a)) and the Series Excess Spread
     Percentage (Item 16(c)) in assessing the current performance of the Trust

     Charge Collections, Yield Collections, Additional Funds and Investment
     Income for any Class of this Series (see Item 3(e)), and (b) the sum of
     (i) the monthly interest for each Class of this Series (see Item 1), (ii)
     the monthly servicing fee for each Class of this Series (see Item 12(d)),
     (iii) the Investor Charge-Off Amount (see Item 8(c)), and (iv) the Credit
     Enhancement Fee (see Item 14(d)), in each case for this Distribution Date.
     The Series Excess Spread Percentage is equal to the Series Excess Spread,
     multiplied by twelve, divided by the Series Investor Interest for this
     Series.

     Finance Charge Collections and are included as such in Item 3 above.

     Group Excess Spread Percentage (Item 16(a)) and the Series Excess Spread
     Percentage (Item 16(c)) in assessing the current performance of the Trust

     Charge Collections, Yield Collections, Additional Funds and Investment
     Income for any Class of this Series (see Item 3(e)), and (b) the sum of
     (i) the monthly interest for each Class of this Series (see Item 1), (ii)
     the monthly servicing fee for each Class of this Series (see Item 12(d)),
     (iii) the Investor Charge-Off Amount (see Item 8(c)), and (iv) the Credit
     Enhancement Fee (see Item 14(d)), in each case for this Distribution Date.
     The Series Excess Spread Percentage is equal to the Series Excess Spread,
     multiplied by twelve, divided by the Series Investor Interest for this
     Series.

 (4) For purposes of allocations to investors, recoveries are treated as
     Finance Charge Collections and are included as such in Item 3 above.

 (1) For series in Group One, investors should refer only to the higher of the
     Group Excess Spread Percentage (Item 16(a)) and the Series Excess Spread
     Percentage (Item 16(c)) in assessing the current performance of the Trust
     and the Receivables.

 (2) Group Excess Spread is the sum of the Series Excess Spreads (as described
     below) for each series in the Group.  The Group Excess Spread Percentage
     is equal to the Group Excess Spread, multiplied by twelve, divided by the
     Series Investor Interests for each series in the Group.

 (3) Series Excess Spread is the difference between (a) the sum of Finance
     Charge Collections, Yield Collections, Additional Funds and Investment
     Income for any Class of this Series (see Item 3(e)), and (b) the sum of
     (i) the monthly interest for each Class of this Series (see Item 1), (ii)
     the monthly servicing fee for each Class of this Series (see Item 12(d)),
     (iii) the Investor Charge-Off Amount (see Item 8(c)), and (iv) the Credit
     Enhancement Fee (see Item 14(d)), in each case for this Distribution Date.
     The Series Excess Spread Percentage is equal to the Series Excess Spread,
     multiplied by twelve, divided by the Series Investor Interest for this
     Series.

 (4) For purposes of allocations to investors, recoveries are treated as
     Finance Charge Collections and are included as such in Item 3 above.

     Group Excess Spread Percentage (Item 16(a)) and the Series Excess Spread
     Percentage (Item 16(c)) in assessing the current performance of the Trust

     is equal to the Group Excess Spread, multiplied by twelve, divided by the
     Series Investor Interests for each series in the Group.

 (3) Series Excess Spread is the difference between (a) the sum of Finance
     Charge Collections, Yield Collections, Additional Funds and Investment
     Income for any Class of this Series (see Item 3(e)), and (b) the sum of
     (i) the monthly interest for each Class of this Series (see Item 1), (ii)
     the monthly servicing fee for each Class of this Series (see Item 12(d)),
     (iii) the Investor Charge-Off Amount (see Item 8(c)), and (iv) the Credit
     Enhancement Fee (see Item 14(d)), in each case for this Distribution Date.
     The Series Excess Spread Percentage is equal to the Series Excess Spread,
     multiplied by twelve, divided by the Series Investor Interest for this
     Series.

 (4) For purposes of allocations to investors, recoveries are treated as
     Finance Charge Collections and are included as such in Item 3 above.

 (1) For series in Group One, investors should refer only to the higher of the
     Group Excess Spread Percentage (Item 16(a)) and the Series Excess Spread
     Percentage (Item 16(c)) in assessing the current performance of the Trust
     and the Receivables.

 (2) Group Excess Spread is the sum of the Series Excess Spreads (as described
     below) for each series in the Group.  The Group Excess Spread Percentage
     is equal to the Group Excess Spread, multiplied by twelve, divided by the
     Series Investor Interests for each series in the Group.

 (3) Series Excess Spread is the difference between (a) the sum of Finance
     Charge Collections, Yield Collections, Additional Funds and Investment
     Income for any Class of this Series (see Item 3(e)), and (b) the sum of
     (i) the monthly interest for each Class of this Series (see Item 1), (ii)
     the monthly servicing fee for each Class of this Series (see Item 12(d)),
     (iii) the Investor Charge-Off Amount (see Item 8(c)), and (iv) the Credit
     Enhancement Fee (see Item 14(d)), in each case for this Distribution Date.
     The Series Excess Spread Percentage is equal to the Series Excess Spread,
     multiplied by twelve, divided by the Series Investor Interest for this
     Series.

 (4) For purposes of allocations to investors, recoveries are treated as
     Finance Charge Collections and are included as such in Item 3 above.

 (1) For series in Group One, investors should refer only to the higher of the
     Group Excess Spread Percentage (Item 16(a)) and the Series Excess Spread
     Percentage (Item 16(c)) in assessing the current performance of the Trust
     and the Receivables.

     is equal to the Group Excess Spread, multiplied by twelve, divided by the
     Series Investor Interests for each series in the Group.

 (3) Series Excess Spread is the difference between (a) the sum of Finance
     Charge Collections, Yield Collections, Additional Funds and Investment
     Income for any Class of this Series (see Item 3(e)), and (b) the sum of
     (i) the monthly interest for each Class of this Series (see Item 1), (ii)
     the monthly servicing fee for each Class of this Series (see Item 12(d)),
     (iii) the Investor Charge-Off Amount (see Item 8(c)), and (iv) the Credit
     Enhancement Fee (see Item 14(d)), in each case for this Distribution Date.
     The Series Excess Spread Percentage is equal to the Series Excess Spread,
     multiplied by twelve, divided by the Series Investor Interest for this
     Series.

 (4) For purposes of allocations to investors, recoveries are treated as
     Finance Charge Collections and are included as such in Item 3 above.

 (1) For series in Group One, investors should refer only to the higher of the
     Group Excess Spread Percentage (Item 16(a)) and the Series Excess Spread
     Percentage (Item 16(c)) in assessing the current performance of the Trust

     is equal to the Group Excess Spread, multiplied by twelve, divided by the
     Series Investor Interests for each series in the Group.

 (3) Series Excess Spread is the difference between (a) the sum of Finance
     Charge Collections, Yield Collections, Additional Funds and Investment
     Income for any Class of this Series (see Item 3(e)), and (b) the sum of
     (i) the monthly interest for each Class of this Series (see Item 1), (ii)
     the monthly servicing fee for each Class of this Series (see Item 12(d)),
     (iii) the Investor Charge-Off Amount (see Item 8(c)), and (iv) the Credit
     Enhancement Fee (see Item 14(d)), in each case for this Distribution Date.
     The Series Excess Spread Percentage is equal to the Series Excess Spread,
     multiplied by twelve, divided by the Series Investor Interest for this
     Series.

 (4) For purposes of allocations to investors, recoveries are treated as
     Finance Charge Collections and are included as such in Item 3 above.

 (1) For series in Group One, investors should refer only to the higher of the
     Group Excess Spread Percentage (Item 16(a)) and the Series Excess Spread
     Percentage (Item 16(c)) in assessing the current performance of the Trust
     and the Receivables.

     is equal to the Group Excess Spread, multiplied by twelve, divided by the
     Series Investor Interests for each series in the Group.

 (3) Series Excess Spread is the difference between (a) the sum of Finance
     Charge Collections, Yield Collections, Additional Funds and Investment
     Income for any Class of this Series (see Item 3(e)), and (b) the sum of
     (i) the monthly interest for each Class of this Series (see Item 1), (ii)
     the monthly servicing fee for each Class of this Series (see Item 12(d)),
     (iii) the Investor Charge-Off Amount (see Item 8(c)), and (iv) the Credit
     Enhancement Fee (see Item 14(d)), in each case for this Distribution Date.
     The Series Excess Spread Percentage is equal to the Series Excess Spread,
     multiplied by twelve, divided by the Series Investor Interest for this
     Series.

 (4) For purposes of allocations to investors, recoveries are treated as
     Finance Charge Collections and are included as such in Item 3 above.

     Charge Collections, Yield Collections, Additional Funds and Investment
     Income for any Class of this Series (see Item 3(e)), and (b) the sum of
     (i) the monthly interest for each Class of this Series (see Item 1), (ii)
     the monthly servicing fee for each Class of this Series (see Item 12(d)),
     (iii) the Investor Charge-Off Amount (see Item 8(c)), and (iv) the Credit
     Enhancement Fee (see Item 14(d)), in each case for this Distribution Date.
     The Series Excess Spread Percentage is equal to the Series Excess Spread,

     Series.

     Finance Charge Collections and are included as such in Item 3 above.

     Group Excess Spread Percentage (Item 16(a)) and the Series Excess Spread

     Charge Collections, Yield Collections, Additional Funds and Investment
     Income for any Class of this Series (see Item 3(e)), and (b) the sum of
     (i) the monthly interest for each Class of this Series (see Item 1), (ii)
     the monthly servicing fee for each Class of this Series (see Item 12(d)),
     (iii) the Investor Charge-Off Amount (see Item 8(c)), and (iv) the Credit
     Enhancement Fee (see Item 14(d)), in each case for this Distribution Date.
     The Series Excess Spread Percentage is equal to the Series Excess Spread,
     multiplied by twelve, divided by the Series Investor Interest for this
     Series.

     Finance Charge Collections and are included as such in Item 3 above.

     Group Excess Spread Percentage (Item 16(a)) and the Series Excess Spread
     Percentage (Item 16(c)) in assessing the current performance of the Trust

     Charge Collections, Yield Collections, Additional Funds and Investment
     Income for any Class of this Series (see Item 3(e)), and (b) the sum of

     (i) the monthly interest for each Class of this Series (see Item 1), (ii)
     the monthly servicing fee for each Class of this Series (see Item 12(d)),
     (iii) the Investor Charge-Off Amount (see Item 8(c)), and (iv) the Credit
     Enhancement Fee (see Item 14(d)), in each case for this Distribution Date.
     The Series Excess Spread Percentage is equal to the Series Excess Spread,

     Series.

 (4) For purposes of allocations to investors, recoveries are treated as
     Finance Charge Collections and are included as such in Item 3 above.
