(f) In the event that the Stop Loss Agreement is not terminated in accordance with the terms of the RCH Letter Agreement, all provisions of the Stock Purchase Agreement relating to the Reassurance Company of Hanover block, including, without limitation, Sections 6.10 and 9.1, shall apply in full as if this Section 5.19 had never been effective.

Section 9.1(d)(ii) of the Stock Purchase Agreement is hereby amended, as follows: the phrase "claims relating to a reserve deficiency under that certain stop-loss reinsurance treaty with Reinsurance Company of Hanover" shall be replaced with "liabilities and obligations arising in connection with the transactions contemplated by the RCH Letter of Intent, including any liabilities relating to the Stop Loss Agreement following its termination, and..." 7. Section 9.1 is hereby further amended by adding a new subsection (f), as follows; 3 (f) claims and liabilities relating to the refusal of American Continental Insurance Company to allow the Company to recapture treaties numbers 652A and 652B prior to the contractual recapture date of December 31, 1999. 8.

In accordance with Section 5.15 of the Stock Purchase Agreement, Schedules 2.2, 3.14, 3.19 and 6.11, respectively, to the Stock Purchase Agreement are each hereby deleted in their entirety as of the date hereof and they are hereby replaced by Schedules A, B, C and D, respectively, attached hereto.
