Closing Date (as defined in Section 5.1(b)), Oracle, either singly or together

Oracle, either singly or together with DI, shall pay to RSL the amount of

                1.3 Termination. On the Commutation Closing Date, all
obligations of the parties contained in, arising from or resulting under the
SNCC Reinsurance Agreement and the RSL Reinsurance Agreement, respectively
(whether due or to become due), shall, effective as of the Commutation Effective
Date, be deemed to have terminated and expired and the respective parties
thereto shall have no further obligation to or rights against each other
thereunder.

                1.4 Letters of Credit Termination Notices. On the Commutation
Closing Date, SNCC and RSL shall provide certifications to Bank of America,
N.A., as letter of credit agent (the "Agent"), with respect to the terminations

respectively, in the forms contemplated by Annex 1 to the respective letters of

(such portion, the "Note Waiver Amount") of the total principal amounts owing to

Section 1.7 hereof and to be allocated among the DI Notes pro rata in accordance
with the respective principal amounts owing to DFG under such notes, and DI will

<PAGE>

                1.6 Redemption of Preference Shares. On the Winding Up
Completion Date, the Trust will waive its right to receive a portion (such
portion, the "Preference Share Waiver Amount" and, taken together with the Note
Waiver Amount, the "Aggregate Waiver Amount") of the aggregate price payable on
redemption of the Preference Shares pursuant to the provisions of the
Certificate of Designation thereof, the Preference Share Waiver Amount to be
determined pursuant to Section 1.7 hereof, and DI will redeem the Preference
Shares at their stated redemption price plus accrued dividends, less the
Preference Share Waiver Amount. The Trust shall deliver to DI each of the
certificates representing the Preferred Shares.

                1.7 Waiver Amounts; DI Contingent Payment.

                (a) The Aggregate Waiver Amount shall be equal to such amount
as, when subtracted from the total outstanding principal amount of the DI Notes
and the total price payable on redemption of the Preference Shares, will cause
the sum of (i) the amounts payable in respect of the DI Notes (inclusive of
accrued interest) and pursuant to the redemption of the Preference Shares
(inclusive of accrued dividends), (ii) the total amount of all costs, charges
and expenses of the winding up of the Liquidating Companies payable pursuant to
the Act and (iii) the total amount of all other liabilities of the Liquidating
Companies remaining to be satisfied in accordance with the Act, all as
determined as of the Winding Up Completion Date (such sum, the "Aggregate
Winding Up Amount"), to be such as, after payment and satisfaction of the
Aggregate Winding Up Amount, will result in an amount being distributable to the
members of DI (other than the Trust and any other holders of preference shares
of DI) pursuant to the Act (the "Distributable Amount") that is equal to
US$12,237,042 (the "Stated Distribution Amount"). If the Distributable Amount
equals or exceeds the Stated Distribution Amount as of the Winding Up Completion
Date, without taking into account the waivers contemplated by Sections 1.5 and
1.6 hereof, the Aggregate Waiver Amount shall be zero.

                (b) The Aggregate Waiver Amount, if any, shall be allocated on a
modified pro rata basis as between the Note Waiver Amount and the Preference
Share Waiver Amount based on the total principal amount owing under the DI Notes
(the "Note Amount"), on one hand, and the total stated redemption price of the
Preference Shares, without regard to accrued dividends (the "Preference Share
Amount"), on the other hand, all as determined of the Winding Up Completion
Date, such that the ratio of the Note Waiver Amount to the Note Amount is
one-half of the ratio of the Preference Share Waiver Amount to the Preference
Share Amount.

                (c) In further consideration of the agreements of DFG and the
Trust set forth in Sections 1.05 and 1.06 hereof, respectively, DI agrees that
if, as of the Winding Up Completion Date, the Distributable Amount is in excess
of the Stated Distribution Amount, without taking into account the waivers
contemplated by Sections 1.5 and 1.6 hereof, DI shall pay to DFG and the Trust
the amount of such excess, such payment to be allocated between DFG and the
Trust pro rata in the same manner as set forth in Section 1.7(b).
