(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.

(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
       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

(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.

    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

    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.

(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.

      (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.

     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
     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.

     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)

     (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,

     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.

     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 (i)

    the Investor Charge-Off Amount (see Item 8(c)), and (iv) the Credit

(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.

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

    Percentage is equal to the Series Excess Spread, multiplied by

    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.

    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.

(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.

(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

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

       (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.

       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
       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
       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
       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)

       (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.
