                               W I T N E S S E T H

                  WHEREAS, each of the Ceding Companies has entered into quota
share reinsurance agreements with Reinsurer, dated as of July 1, 2003
(collectively, the "Quota Share Reinsurance Agreements"), pursuant to which RIC,

assume, on a 100% quota share basis, the liabilities and obligations arising out
of the Reinsured Contracts (as such term is defined in the respective Quota

                  WHEREAS, pursuant to Section 9.1 of the respective Quota Share
Reinsurance Agreements, Reinsurer, as grantor, established the "Underwriter's
Reinsurance Company, Grantor" trust (the "Trust") pursuant to a trust agreement
as of July 1, 2003 (the "Trust Agreement") naming the Ceding Companies as sole
and exclusive beneficiaries of the Trust, and agreed to maintain in such Trust
cash and other Acceptable Investments (as such term is defined in the Trust
Agreement (collectively, the "Qualifying Assets")) in an amount (the "Required
Balance") equal to Reinsurer's aggregate obligations to the Ceding Companies
under the Quota Share Reinsurance Agreements, net of (i) collectible Reinsurance
Recoverables (as such term is defined in the respective Quota Share Reinsurance
Agreements), (ii) RIC's obligations to

<PAGE>

Landmark under the RIC (Landmark) Quota Share Reinsurance Agreement (as such
term is defined therein) and (iii) premium receivables;

                  WHEREAS, pursuant to Section 9.2 of the respective Quota Share
Reinsurance Agreements, each of the Ceding Companies and Reinsurer have agreed
to enter into this Assignment Agreement, pursuant to which Reinsurer will assign
to the Trust, and grant the Trust a first priority perfected security interest
in, all of Reinsurer's right, title and interest in, to and under all Cat Cover
Reinsurance Recoverables (as such term is defined in the respective Quota Share
Reinsurance Agreements) under the catastrophe excess of loss reinsurance treaty
or treaties purchased by the Reinsurer with respect to the Reinsured Contracts
(the "Assignment"); and

                  WHEREAS, the parties hereto agree and acknowledge that the
purpose of the Assignment is to secure Reinsurer's obligation to the Ceding
Companies to maintain Qualifying Assets in the Trust at or above the Required
Balance.

                  NOW, THEREFORE, in consideration of the foregoing and the
respective covenants, agreements and conditions set forth herein and in the
Quota Share Reinsurance Agreements, and for other good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged, the
parties hereto, intending to be legally bound, agree as follows:

                  Section 1. DEFINITIONS. Certain capitalized terms used but not
defined in this Assignment Agreement shall have the meanings ascribed to such
terms in the respective Quota Share Reinsurance Agreements or the Trust
Agreement.

                  Section 2. ASSIGNMENT AND ASSUMPTION.

                                       2
<PAGE>

                  (a)      Subject to Sections 2(d) and 2(e) hereto, Reinsurer
hereby assigns, transfers, and conveys to the Trust all of Reinsurer's right,
title and interest in and to all of the Cat Cover Reinsurance Recoverables.

                  (b)      Reinsurer agrees and acknowledges that the Assignment
shall, without limitation, grant the Trustee the exclusive right to collect the
Cat Cover Reinsurance Recoverables directly from the applicable third party
reinsurer, but only if the Qualifying Assets are less than the Required Balance,
and to retain the Cat Cover Reinsurance Recoverables to the extent that the
aggregate fair market value of Qualifying Assets in the Trust do not at least
equal the Required Balance. Reinsurer further agrees that it shall cooperate
with the Beneficiary in instructing the Trustee to assign its right to collect
such Cat Cover Reinsurance Recoverables directly from the applicable third party
reinsurer to the Ceding Companies, as named beneficiaries of the Trust if the
aggregate fair market value of Qualifying Assets in the Trust do not at least
equal the Required Balance. Any Cat Cover Reinsurance Recoverables which are
subject to the Assignment collected by the Reinsurer, Trustee and/or the Ceding
Companies shall be deposited directly into the Trust. The failure by the
Reinsurer, Trustee and/or the Ceding Companies to collect the Cat Cover
Reinsurance Recoverables shall not relieve Reinsurer of any of its obligations
under the Quota Share Reinsurance Agreements to maintain Qualifying Assets in
the Trust in an amount equal to the Required Balance.

                  (c)      Reinsurer agrees and acknowledges that the Assignment
shall, without limitation, entitle the Trustee (and/or the Ceding Companies to
the extent the Trustee assigns its rights hereunder to the Ceding Companies) to
enforce in the name of Reinsurer any right or claim of Reinsurer with respect to
the Cat Cover Reinsurance Recoverables. Any assignment by the Trustee to the
Ceding Companies under this Assignment Agreement shall be

                                       3
<PAGE>

solely for the purpose of enabling the Ceding Companies, as agent for the
Trustee, to collect such Cat Cover Reinsurance Recoverables for deposit into the
Trust.

                  (d)      The parties hereto agree and acknowledge that the
purpose of the Assignment is to secure Reinsurer's obligation to the Ceding
Companies to maintain Qualifying Assets in the Trust at or above the Required
Balance. The rights of the Trustee under this Assignment Agreement with respect
to collection of the Cat Cover Reinsurance Recoverables directly from the
applicable third party reinsurer and enforcement of claims (or, if such rights
are assigned to the Ceding Companies pursuant to the Trust Agreement, the Ceding
Companies), are limited to the extent of the deficiency, if any, in the Required
Balance.

                  (e)      The parties agree that all the proceeds of the Cat
Cover Reinsurance Recoverables collected by the Trustee in excess of the amount
necessary to maintain Qualified Assets in the Trust in an amount equal to the
Required Balance shall be remitted by wire transfer of immediately available
funds to the Reinsurer in accordance with Section 4.2(a) of the Trust Agreement.

                  (f)      The parties hereto agree and acknowledge that while
the Assignment may not be revoked or terminated except pursuant to Section 6
hereof, Reinsurer will not be obligated to pay any Cat Cover Reinsurance
Recoverables actually collected to the Trust, so long as, at the time any of the
Cat Cover Reinsurance Recoverables are collected, the aggregate amount of
Qualifying Assets maintained in the Trust is at or above the Required Balance.
In the event the aggregate amount of cash and other Qualifying Assets maintained
in the Trust is below the Required Balance, the Assignment hereunder shall be of
all Cat Cover Reinsurance Recoverables due and owing, regardless of the amount
of the deficiency in the Trust.

the foregoing requirements and shall provide the Trustee with the requisite
power of attorney in order to allow the Trustee to execute and deliver UCC
financing statements with respect to any and all intangible assets assigned or
transferred to the Trustee hereunder. All costs and expenses incurred in
connection with obtaining a first priority perfected security interest shall be
