Dear Ken:

     This is to confirm our discussions regarding our agreement to waive certain
notice provisions under your employment agreement dated January 11, 1999 with
INSpire Insurance Solutions, Inc. (the "COMPANY") Section 8(c) of your
employment agreement provides that you may terminate the employment agreement
upon one (l) year written notice. Section 8(d) of the employment agreement
provides that the Company may terminate the employment agreement upon 180 days
notice. In view of the Company's decision to pursue strategic alternatives and
the inherent uncertainty regarding what, if any, alternatives may be pursued, we
have agreed that it would be appropriate to waive the notice requirements under
the employment agreement as described below.

     Accordingly, we agree as follows:

     A.   You agree that no notice of termination of employment may be given by
          you prior to January 1, 2000. After January 1, 2000, you may elect to
          terminate the employment agreement upon 60 days prior written notice
          to the Company; provided, however, that the effective date for
          termination of employment shall not be earlier than March 31, 2000.
          You agree to continue to perform the duties contemplated by your
          employment agreement through at least March 31, 2000 and in connection
          therewith you acknowledge that you will continue to serve as Chief
          Financial Officer of the Company with responsibility for the
          preparation, execution and filing of the Company's Annual Report or
          Form 10K for the year ending December 31, 1999.

     B.   Subject to your compliance with Section A above, in the event that you
          elect to terminate the employment agreement by giving notice after
          January 1, 2000, (i) you will be entitled to the compensation upon
          termination as specified in Sections 9(a) and 9(d) of your employment
          agreement, and (ii) you may elect to receive a lump sum payment equal
          to the present value of the amount of compensation upon termination
          payable to you discounted by the then current Treasury Bill rate for
          the remaining period of time during which such compensation is payable
          pursuant to Section 9(d) of your employment agreement.

     C.   After January 1, 2000, the Company may elect to terminate your
          employment agreement at any time upon 60 days written notice to you.

     D.   In the event of termination of your employment agreement by you or by
          the Company, you agree to resign as of the date of such termination
          any position you hold as an officer of the Company.

     Except as specifically described above, this letter shall not be deemed to
be a waiver or modification of any other provision of your employment agreement.
