Share Reinsurance Agreement will be increased by reason of the inability of
Cedent to collect any reinsurance from any such Unaffiliated Reinsurer, whether
specific or general, that may have become due from them, whether that inability
arises from insolvency or otherwise, except that Reinsurer's liability under
this Landmark Quota Share Reinsurance Agreement will not be increased due to

extent of a proportionate share of the benefit which may accrue to Cedent as a
result of the defense undertaken by Reinsurer.

<PAGE>

         and together with cash, "Qualifying Assets") in an amount equal to
         Royal's estimate of the Net Unearned Premium Reserve less the amount of

         Reserve by Cedent at or prior to the Closing Date less the amount of
         the Aggregate Ceding Commission; and provided, further, with respect to

         Cedent shall cause RSUI to place, on the Closing Date, Qualifying

                           (ii)     Cedent shall assign to the Trust Account all
         Premium Receivables net of premium receivables to be ceded to the
         Unaffiliated Reinsurers with respect to such Reinsured Contracts (the
         "Net Premium Receivables") in accordance with the Assignment of Net
         Premium Receivables Agreement attached hereto as EXHIBIT C. Net Premium
         Receivables which are actually collected shall be referred to herein as
         the "Collected Net Premium."

                           (iii)    Reinsurer shall place in the Trust Account
         Qualifying Assets in an amount equal to the Aggregate Ceding

         accordance with the Assignment of Reinsurance Recoverables Agreement
         attached hereto as EXHIBIT D.

                  (b)      At any time on and after the Closing Date, until the

and Reinsurer agree to the following:

                           (i)      Cedent shall, and Reinsurer shall cause RSUI
         to place in the Trust Account all Collected Net Premium as soon as
         practicable upon receipt of the Collected Net Premium, but no later
         than five (5) Business Days after receipt of such Collected Net
         Premium.

                           (ii)     In the event Cedent reasonably determines
         that any portion of the Net Premium Receivables is uncollectible,
         Reinsurer shall place in the Trust Account Qualifying Assets equal to
         the amount of the Net Premium Receivables which is deemed
         uncollectible. Net Premium Receivables shall be deemed uncollectible if
         they become due and owing for 90 days or more.

                           (iii)    In the event Cedent reasonably determines
         that any Reinsurance Recoverables from Unaffiliated Reinsurers relating
         to the Reinsured Contracts are uncollectible, Reinsurer shall place in
         the Trust Account Qualifying Assets equal to the amount of Reinsurance
         Recoverables which are deemed uncollectible, but only to the extent the
         obligations relate to the Reinsured

                                       13

<PAGE>

         Liabilities. If such uncollectiblity is due to the creditworthiness of
         Unaffiliated Reinsurers, Cedent shall make such determination
         consistent with the treatment of other recoverables from such
         reinsurers in its own financial statements.

                           (iv)     In the event the aggregate fair market value
         of the assets held in the Trust Account, determined pursuant to the
         Trust Agreement (the "Market Value"), is below the Required Balance,
         Reinsurer shall deposit in the Trust Account such additional Qualifying
         Assets as may be necessary to increase the Market Value of the Trust
         Account assets to the Required Balance.

                  Section 9.3 Reporting and Payment.

                  (a)      The assets held in the Trust Account shall be
invested in permissible investments under the investment provisions of the
insurance laws of Delaware and New Hampshire and in accordance with the
investment guidelines of Reinsurer attached hereto as EXHIBIT E (the "URC
Investment Guidelines"). As long as the Trust Agreement remains in force, no
amendments to the URC Investment Guidelines shall be made without the express
written consent of Cedent, which consent shall not be unreasonably denied or
delayed. Reinsurer shall calculate the Required Balance and the Market Value as
of the last day of each month and report the amount of the Required Balance and
the Market Value, together with supporting detail, to Cedent and the Trustee of
the Trust Account (the "Trustee") within fifteen (15) days after the end of such
month. The parties hereto shall agree upon mutually satisfactory procedures for
the calculation of the Required Balance and the Market Value.

                  (b)      No later than five (5) Business Days after
Reinsurer's delivery of such report (or within 2 Business Days of agreement or
determination of any dispute pursuant to Section 9.3(c)), Reinsurer shall
deposit in the Trust Account such additional Qualifying Assets as may be
necessary to increase the Market Value of the Trust Account assets to the
Required Balance. No later than five (5) Business Days after Cedent's receipt of
such report (or within 2 Business Days of agreement or determination of any
dispute pursuant to Section 9.3(c)), Cedent shall direct Trustee to pay to
Reinsurer any amount by which the aggregate Market Value of the Trust Account
assets exceeds the Required Balance. Prior to delivering any assets for deposit
in the Trust Account, Reinsurer shall execute assignments or endorsements in
blank of all of Reinsurer's right, title and interest in such assets, so that,
upon the direction of Cedent, Trustee may negotiate any such assets without
consent or signature of Reinsurer or any person or entity.

                  (c)      In the event that Cedent disagrees with Reinsurer's
calculation of the Required Balance and/or the Market Value other than in
respect of incurred but not reported reserves, it shall notify the Reinsurer of
such disagreement in writing. If the dispute cannot be agreed between Cedent and
Reinsurer within five (5) Business Days of notification, the dispute shall be
resolved by the Neutral Auditors in accordance with the provisions of Section
1.10 of the Acquisition Agreement.

monthly report described in Section 9.3(a), (i) within thirty (30) days after
the end of every calendar quarter, a review prepared by a nationally recognized
independent actuarial firm of Reinsurer's loss and expenses reserves supporting
Reinsurer's calculations of the Required Balance and the Market Value; and (ii)
within sixty (60) days after the end of each calendar year, an opinion issued by
a nationally recognized independent actuarial firm, supporting Reinsurer's
calculation of the Required Balance and the Market Value.

Cedent, or any successor by operation of law of Cedent, including any

         or

                           (iv)     to secure the Trust Account assets upon any
         attempt by Reinsurer to terminate the Trust Account without
         establishing other collateral acceptable to Cedent, other than in
         accordance of the terms of the Trust.

                  (b)      Cedent shall withdraw assets from the Trust to (i)

                                  ARTICLE XII

<PAGE>

insurance regulatory authorities in order for Cedent to obtain full credit on

Agreement, Reinsurer, upon the request of Cedent, will immediately establish, at
its sole cost and option, a Trust Agreement and/or a Qualifying Letter of Credit
in an amount necessary to permit Cedent to obtain full credit for such
reinsurance in such jurisdiction.

                  Section 12.2 Notification. Reinsurer shall notify Cedent

                                   ARBITRATION

                  Section 13.1 Arbitration. As a condition precedent to any
cause of action, any and all disputes between Cedent and Reinsurer arising out
of, relating to, or concerning this Landmark Quota Share Reinsurance Agreement,
whether sounding in contract or tort and whether arising during or after
termination of this Landmark Quota Share Reinsurance Agreement, including
whether the dispute is subject to arbitration, shall be submitted to the
decision of a board of arbitration composed of two arbitrators and an umpire
("Board") meeting at a site in Wilmington, Delaware. The arbitration shall be
conducted under the Federal Arbitration Act and shall proceed as set forth
below.

                  Section 13.2 Notice of Arbitration. A notice requesting
arbitration, or any other notice made in connection therewith, shall be in
writing and shall be sent certified or registered mail, return receipt requested
to the affected parties. The notice requesting arbitration shall state in
particulars all issues to be resolved in the view of the claimant, shall appoint
the arbitrator selected by the claimant and shall set a tentative date for the
hearing, which date shall be no sooner than ninety (90) days and no later than
one hundred fifty (150) days from the date that the notice requesting
arbitration is mailed. Within thirty (30) days of receipt of claimant's notice,
the respondent shall notify claimant of any additional issues to be resolved in
the arbitration and of the name of its appointed arbitrator.

                  Section 13.3 Arbitration Panel. Unless otherwise mutually
agreed, the members of the Board shall be impartial and disinterested and shall
be active or former executive officers of property-casualty insurance companies,
reinsurance companies, or Lloyd's Underwriters or active or inactive lawyers
with at least twenty (20) years of experience in insurance and reinsurance.
Cedent and Reinsurer shall each appoint an arbitrator and the two (2)
arbitrators shall choose an umpire before instituting the hearing. If the
respondent fails to appoint its arbitrator within thirty (30) days after having
received claimant's written request for arbitration, the claimant is authorized
to and shall appoint the second arbitrator. If the two arbitrators fail to agree
upon the appointment of an umpire within thirty (30) days after notification of
the appointment of the second

                                       17

<PAGE>

arbitrator, within ten (10) days thereof, the two (2) arbitrators shall request
the American Arbitration Association ("AAA") to appoint an umpire for the
arbitration with the qualifications set forth in this Article. If the AAA fails
to name an umpire, either party may apply to the court named below to appoint an
umpire with the above required qualifications. The umpire shall promptly notify
in writing all parties to the arbitration of his selection and of the scheduled
date for the hearing. Upon resignation or death of any member of the Board, a
replacement shall be appointed in the same fashion as the resigning or deceased
member was appointed.

                  Section 13.4 Submission of Briefs. The claimant and respondent
shall each submit initial briefs to the Board outlining the issues in dispute
and the basis, authority and reasons for their respective positions within
thirty (30) days of the date of notice of appointment of the umpire. The
claimant and the respondent may submit reply briefs to the Board within ten (10)
days after filing of the initial brief(s). Initial and reply briefs may be
amended by the submitting party at any time, but not later than ten (10) days
prior to the date of commencement of the arbitration hearing. Reasonable
responses shall be allowed at the arbitration hearing to new material contained
in any amendments filed to the briefs but not previously responded to.

                  Section 13.5 Arbitration Board's Decision. The Board shall
make a decision and award with regard to the terms of this Landmark Quota Share
Reinsurance Agreement and the original intentions of the parties to the extent
reasonably ascertainable. The Board's decision and award shall be in writing and
shall state the factual and legal basis for the decision and award. The decision
and award shall be based upon a hearing in which evidence shall be allowed and
which the formal rules of evidence shall not strictly apply but in which cross
examination and rebuttal shall be allowed. At its own election or at the request
of the Board, either party may submit a post-hearing brief for consideration of
the Board within twenty (20) days of the close of the hearing. The Board shall
make its decision and award within thirty (30) days following the close of the
hearing or the submission of post-hearing briefs, whichever is later, unless the
parties consent to an extension. Every decision by the Board shall be by a
majority of the members of the Board and each decision and award by the majority
of the members of the Board shall be final and binding upon all parties to the
proceeding.

                  Section 13.6 Jurisdiction. Either party may apply to the
Chancery Court of the State of Delaware for an order compelling arbitration or
confirming any decision and the award; a judgment of that Court shall thereupon
be entered on any decision or award. If such an order is issued, the attorneys'
fees of the party so applying and court costs will be paid by the party against
whom confirmation is sought. The Board may award interest calculated from the
date the Board determines that any amounts due the prevailing party should have
been paid to the prevailing party.

                  Section 13.7 Expenses. Each party shall bear the expense of
the one arbitrator appointed by it and shall jointly and equally bear with the
other party the expense of any stenographer requested, and of the umpire.

<PAGE>

                  Section 13.8 Production of Documents and Witnesses. Subject to
customary and recognized legal rules of privilege, each party participating in
the arbitration shall have the obligation to produce those documents and as
witnesses to the arbitration those of its employees as any other participating
party reasonably requests providing always that the same witnesses and documents
be obtainable and relevant to the issues before the arbitration and not be
unduly burdensome or excessive. The parties may mutually agree as to pre-hearing
discovery prior to the arbitration hearing and in the absence of agreement, upon
the request of any party, pre-hearing discovery may be conducted as the Board
shall determine in its sole discretion to be in the interest of fairness, full
disclosure, and a prompt hearing, decision and award by the Board. The Board
shall be the final judge of the procedures of the Board, the conduct of the
arbitration, of the rules of evidence, the rules of privilege and production and
of excessiveness and relevancy of any witnesses and documents upon the petition
of any participating party. To the extent permitted by law, the Board shall have
the authority to issue subpoenas and other orders to enforce their decisions.

                  Section 13.9 Relief Available. Nothing herein shall be
construed to prevent any participating party from applying to the Chancery Court
of the State of Delaware to issue a restraining order or other equitable relief
to maintain the "status quo" of the parties participating in the arbitration
pending the decision and award by the Board or to prevent any party from
incurring irreparable harm or damage at any time prior to the decision and award
of the Board. The Board shall also have the authority to issue interim decisions
or awards in the interest of fairness, full disclosure, and a prompt and orderly
hearing and decision and award by the Board.

                  Section 13.10 Consolidation. In the event that there is a
dispute between the Cedent and Reinsurer which implicates the provisions of this
Landmark Quota Share Reinsurance Agreement and the Landmark Administrative
Services Agreement, Cedent and Reinsurer hereby agree to consolidate any such
dispute under such agreements in a single arbitration proceeding.

                                  ARTICLE XIV

                            MISCELLANEOUS PROVISIONS

                  Section 14.1 Amendment, Modification and Waiver. This Landmark
Quota Share Reinsurance Agreement may not be amended, modified or waived except
by an instrument or instruments in writing signed and delivered on behalf of
each of the parties hereto. No failure or delay by any party in exercising any
right, power or privilege hereunder shall operate as a waiver thereof nor shall
any single or partial exercise thereof preclude any other or further exercise
thereof or the exercise of any other right, power or privileged. The rights and
remedies herein provided shall be cumulative and not exclusive of any rights or
remedies provided by law.

                  Section 14.2 Entire Agreement. This Landmark Quota Share
Reinsurance Agreement (together with the exhibits hereto and the other
agreements,

                                       19

<PAGE>

documents and instruments delivered in connection herewith) the Acquisition
Agreement, the Landmark Administrative Services Agreement and the other
Ancillary Agreements constitute the entire agreement among the parties with
respect to the subject matter hereof and thereof and supersede all other prior
agreements and understandings, both written and verbal, among the parties or any
of them with respect to the subject matter hereof.

                  Section 14.3 Governing Law. This Landmark Quota Share
Reinsurance Agreement shall be governed by and construed in accordance with the
laws of the State of Delaware, regardless of the laws that might otherwise
govern under applicable principles of conflicts of laws thereof.

                  Section 14.4 Severability. Any term or provision of this
Landmark Quota Share Reinsurance Agreement which is invalid or unenforceable in
any jurisdiction shall, as to that jurisdiction, be ineffective to the extent of
such invalidity or unenforceability without rendering invalid or unenforceable
the remaining terms and provisions of this Landmark Quota Share Reinsurance
Agreement or affecting the validity or enforceability of any of the terms or
provisions of this Landmark Quota Share Reinsurance Agreement in any other
jurisdiction. If any provision of this Landmark Quota Share Reinsurance
Agreement is so broad as to be unenforceable, the provision shall be interpreted
to be only so broad as would be enforceable.

                  Section 14.5 Counterparts. This Landmark Quota Share
Reinsurance Agreement may be executed in counterparts, each of which shall be
deemed to be an original, but all of which shall constitute one and the same
agreement.

                  Section 14.6 Consent to Jurisdiction. Each of the parties
hereto irrevocably and unconditionally submits to the exclusive jurisdiction of
the state and federal courts located in the State of Delaware for the purposes
of enforcing this Landmark Quota Share Agreement or the Landmark Administrative
Services Agreement. If any action is brought in a state court, the parties shall
take such actions as are within their control to cause any matter contemplated
hereby to be assigned to the Chancery Court of the State of Delaware. In any
action, suit or other proceeding, each of the parties hereto irrevocably and
unconditionally waives and agrees not to assert by way of motion, as a defense
or otherwise any claims that it is not subject to the jurisdiction of the above
courts, that such action or suit is brought in an inconvenient forum or that the
venue of such action, suit or other proceeding is improper. Each of the parties
hereto also agrees that any final and unappealable judgment against a party
hereto in connection with any action, suit or other proceeding shall be
conclusive and binding on such party and that such award or judgment may be
enforced in any court of competent jurisdiction, either within or outside of the
United States. A certified or exemplified copy of such award or judgment shall
be conclusive evidence of the fact and amount of such award or judgment.

                  Section 14.7 Third Party Beneficiaries. Except for the
provisions of Article XI, nothing in this Landmark Quota Share Reinsurance
Agreement, express or implied, is intended to or shall confer upon any person,
other than the parties hereto any

                                       20

<PAGE>

rights, benefits or remedies of any nature whatsoever under or by reason of this
Landmark Quota Share Reinsurance Agreement.

                  Section 14.8 Binding; Assignment. This Landmark Quota Share
Reinsurance Agreement shall be binding upon and inure to the benefit of the
parties hereto and their respective successors and assigns. Neither this
Landmark Quota Share Reinsurance Agreement, nor any rights, interests or
obligations hereunder, may be directly or indirectly assigned, delegated,
sublicensed or transferred by any party to this Landmark Quota Share Reinsurance
Agreement, in whole or in part, to any other person (including any bankruptcy
trustee) by operation of law or otherwise, whether voluntarily or involuntarily,
without the prior written consent of the parties hereto.

                  Section 14.9 Specific Performance. The parties recognize and
agree that if for any reason any of the provisions of this Landmark Quota Share
Reinsurance Agreement are not performed in accordance with their specific terms
or are otherwise breached, immediate and irreparable harm or injury would be
caused for which money damages would not be an adequate remedy. Accordingly,
each party agrees that, in addition to any other available remedies, each other
party shall be entitled to an injunction restraining any violation or threatened
violation of any of the provisions of this Landmark Quota Share Reinsurance
Agreement without the necessity of posting a bond or other form of security
pending the outcome of any arbitration. In the event that any action should be
brought in equity to enforce any of the provisions of this Landmark Quota Share
Reinsurance Agreement, no party will allege, and each party hereby waives the
defense, that there is an adequate remedy at law.

                  Section 14.10 Descriptive Headings. The descriptive article

good faith" or any similar doctrine in connection with the formation or
performance of this Agreement.

applicable to both the singular and the plural forms of such term, and words
denoting any gender shall include all genders. Where a word or phrase is defined
herein, each of its other grammatical forms shall have a corresponding meaning.

                  Section 14.16 Construction. This Landmark Quota Share
