                                       5

         arrangement, agreement or policy;

4.1.15   to share information received from CGU, including any information in

         Insurer in connection with Business Covered.

4.2      CGU (for itself and as agent for each of the CGU Insurers) hereby
         grants to the Administrator all such powers as are necessary, desirable
         or expedient in order for the Administrator to provide the Run-off
         Functions including the powers set out in Section 4.1. The Run-off
         Functions which will be undertaken by the Administrator will include
         all matters relating to the administration, settlement and payment of
         claims arising under the Business Covered, together with all other
         matters required to give full effect to the terms of the Aggregate
         Reinsurance Agreement and the run-off of the Business Covered,
         including the matters set out in Article IV and extending to claims
         arising under inwards insurance and reinsurance business, to claims
         recoveries under outwards reinsurance policies protecting the Business
         Covered and to the pursuit and recovery of salvage and/or subrogated
         claims.

4.3      CGU shall (and shall procure that the CGU Insurers shall) enter into
         such powers of attorney or other forms of authority as the
         Administrator may from time to time reasonably require to enable the
         Administrator to exercise on behalf of each CGU Insurer such powers as
         are necessary, desirable or expedient for the provision of and
         performance by the Administrator of the Run-off Functions.

4.4      The Administrator shall be entitled, for its own account and in its own
         responsibility to employ and pay sub-agents or contractors in any part
         of the world to perform or co-operate in performing any of the Run-off
         Functions (or performing any of the Administrator's other obligations
         under this Agreement) as the Administrator may in its discretion
         determine, provided such delegation shall not be made to subagents or
         others with potential conflicts of interest, without first disclosing
         such potential conflicts and seeking the written permission of
         Reinsured, which will not be unreasonably withheld. Nothing in the
         foregoing provision shall apply to the Administrator's right to employ
         corporations directly or indirectly owned by Berkshire Hathaway Inc. as
         sub-agents or contractors. The Administrator may delegate any of its
         duties to be performed or powers to be exercised, including this power
         of delegation, under this Agreement, provided that the Administrator
         shall be and remain responsible at all times for the acts and omissions
         of any such sub-agent or contractor or any person to whom they may
         delegate any such duties or powers. Any damages resulting from such
         acts or omissions (other than damages of whatsoever nature included in
         the definition of Ultimate Net Loss) shall not impair the Aggregate.

                                       8


4.5      Where the Administrator provides run-off services for a claim or
         related claims which are partially or in whole not Business Covered
         either due to lack of information or indivisibility of the claim or
         related claims, CGU shall reimburse Administrator for the direct and
         shared costs of providing such services with allocation of the direct
         costs between Administrator and CGU to be on the basis of exposure each
         had on the claim in accordance with Section 5.1. If Administrator has
         reason to believe that a claim it is handling is partially not business
         covered and the Administrator has reason to believe that CGU's exposure
         on the claim or related claims is in excess of $100,000, Administrator
         shall promptly notify the Senior Vice President of CGU's claims
         department or his designee and the parties shall reach a good faith
         agreement on the handling of the claim or related claims. Direct and
         shared costs as referenced herein refers to the salary, benefits and
         allocated shared costs of the claims handler.

4.6      All extra contractual damages that result from claims handling
         performed after the Effective Date shall be the responsibility of the
         Administrator and shall not impair the Aggregate to the extent such
         damages are not Ultimate Net Loss under the Aggregate Reinsurance
         Agreement.

4.7      Whenever there are claims that involve the Reinsured and also involve
         insurers, reinsurers or companies that are owned, administered or one
         hundred percent reinsured by a direct or indirect subsidiary of
         Berkshire Hathaway Inc., the Administrator agrees that it will handle
         claims under this Agreement in good faith and with due regard for the
         singular interests of the Reinsured and CGU.

4.8      Document retention policies of Reinsured and Administrator, concerning
         all documents relating to Business Covered, will not be changed without
         the prior consent of both parties.

                                    ARTICLE V

                    RUN-OFF SERVICES FROM THE EFFECTIVE DATE

From the Effective Date and through the remainder of the term of this Agreement
and subject to its terms and conditions, CGU shall provide to Administrator
Run-Off Services.

BASIS FOR DEVELOPING COST OF SERVICES

5.1      Direct costs will be aggregated discretely where possible. Shared costs
         will be split based on allocation methodology agreed between the
         parties. Where feasible, expense allocation will be done by actual
         allocated costs by specific study and/or

                                       9


         direct allocations. If the expense required to derive allocated costs
         by specific study and/or direct allocation is more than the value
         derived by using these methods, then appropriate agreed indirect
         methods will be used. CGU shall not charge for any service that is not
         included within Administrator's obligations under this Agreement.

         CGU shall at the request of the Administrator provide services to the
         Administrator up to the date indicated below:

INFORMATION TECHNOLOGY SERVICES

5.2      CGU agrees to maintain current support levels for the Information
         Technology Systems, services and applications currently used in
         connection with the Run-Off Function for the period from the Effective
         Date to December 31, 2002 at Administrator's request.

         The charge for Information Technology Services will be in three
         components. The first component is the network service charge, referred
         to by CGU Information Technology Department as data-mega chargeback
         which is the monthly connectivity fee. The charge will be at the same
         rate as for CGU users. The second component is a pro rata share of
         claims systems support costs based on transaction volume. The third
         component will be for additional services or development work which, if
         requested by the Administrator, will be costed separately in accordance
         with Section 5.1.

ACCOUNTING SERVICES

5.3      CGU agrees to maintain at Administrator's request current support
         levels for the accounting services for the period from the Effective
         Date to December 31, 2001, based on a cost analysis by each supporting
         area in accordance with Section 5.1, including, but not limited to,
         Reinsurance Accounting, Payroll, Cash Accounting, Fixed Assets, Travel
         and Accounts Payable.

These costs do not include any additional services or development work which, if
requested by the Administrator, will be costed separately provided such costs
are not otherwise included within this Agreement or the Aggregate Reinsurance
Agreement.

CORPORATE SERVICES

5.4      CGU agrees to provide the following services at cost in accordance with
         Section 5.1 on a continuing basis as requested by the Administrator:

         Human Resources

         Employee Benefit Programs Administration

         Recruiting

                                       10


         Facilities Planning

         During the period of time Administrator occupies the premises pursuant
         to Article XVIII, CGU agrees to provide the following services at cost
         in accordance with Section 5.1

         Mail

         Cafeteria

         Purchasing

         Storage

         services of maintaining the filing room and related services currently
         provided in connection with the file room with costs of the file room
         and delivery service to be allocated in accordance with Section 5.1.

5.6      At the request of Administrator and upon consent of CGU, CGU may
         provide additional services to Administrator, provided the parties
         mutually agree upon the scope of such additional services to be
         provided and the compensation to be paid. Therefore Administrator will
         compensate CGU for the direct costs, and support costs of providing any
         service under this Agreement, including a pro rata portion of the
         direct salaries and benefits of persons whose services are used in
         providing those services.

5.7      Administrator shall have no liability for any termination obligations
         of CGU or its direct or indirect subsidiaries or affiliates to
         employees of CGU who are terminated by CGU prior to the effective date,
         nor shall Administrator have any liability for pension or other
         obligations of CGU to such employees of CGU who may be terminated by
         CGU as a result of this Agreement or the Aggregate Reinsurance
         Agreement.

5.8      For purposes of pension expense calculation the Reinsured will,
         annually, engage the services of Watson Wyatt or other qualified
         pension actuaries to determine the appropriate pension and post
         retirement expense amounts. Administrator will reimbursement Reinsured
         for such pension expenses as part of ULAE.

5.9      CGU shall provide billing statements to Administrator monthly of
         compensation due during the period reflected. The monthly billings
         shall be payable within thirty (30) days of Administrator's receipt of
         each such billing.

                                       11


5.10     The Services provided by CGU shall (i) comply with applicable laws and
         governmental regulations and (ii) be of the same standards of diligence
         and business conduct as CGU follows in its own business operations. If
         such compliance is impossible for reasons beyond its control, CGU will
         notify Administrator of that fact and the reasons for noncompliance.

                                   ARTICLE VI

                                 CLAIMS HANDLING

The Administrative Services with respect to claims shall include the following:

CLAIM ADMINISTRATION SERVICES.

6.1      Administrator shall acknowledge, consider, review, investigate, deny,
         settle, pay or otherwise dispose of each claim that constitutes
         Business Covered (each a "Claim" and collectively the "Claims").
         Administrator shall pay Claims and associated expenses as Ultimate Net
         Loss under the Aggregate Reinsurance Agreement and subject to the terms
         of the Aggregate Reinsurance Agreement.

6.2      Description of Claim Administration Services. Without limiting the
         foregoing, Administrator shall:

6.2.1    establish, maintain and organize Claim files and maintain and organize
         other Claims-related records;

6.2.2    review all Claims and determine whether the Claimant is eligible for
         payment and if so, the nature and extent of such payment;

6.2.3    maintain trained claims personnel;

6.2.4    prepare and distribute to the appropriate recipients any reports
         required by applicable law;

6.2.5    respond to any complaints made by any insurance regulatory authority,
         court or government agency, whether federal, state or other (a
         "Regulator") relating to actions or omissions within the scope of the
         Administrator's authority, within the earlier of (i) the Regulator's
         requested time frame for response, or (ii) the time frame as allowed by
         applicable law; a copy of such response shall be promptly provided to
         the Senior Vice President Claims of CGU or his designee;

                                       12


6.2.6    promptly notify the Senior Vice President Claims of CGU or his designee
         of any complaints initiated by a Regulator and not within the scope of
         the foregoing paragraph 6.2.5. The Insurer shall respond to such
         complaints, with a copy to Administrator. Insurer shall provide any
         response to Administrator for its prior approval (which shall not be
         unreasonably withheld) as soon as reasonably practicable, (provided
         that any approval of Administrator shall be deemed given if no
         objection is received within five days following delivery to the
         Administrator of the definitive response and any additional information
         requested by Administrator);

6.2.7    respond promptly to all written or oral Claims-related communications
         that Administrator reasonably believes to require a response;

6.2.8    maintain a complaint log with respect to the Reinsured Contracts in
         accordance with applicable requirements of Regulators and provide a
         copy of such log upon Insurer's request;

                                   ARTICLE VII

                       REGULATORY COMPLIANCE AND REPORTING

7.1      Commencing on the Inception Date, Administrator shall take all
         necessary action within its control so that the Insurers, solely with
         respect to the Business Covered, satisfy all current and future
         informational reporting and any other requirements imposed by any
         Regulator. Without limiting the foregoing, Administrator shall timely
         prepare such reports and summaries, including statistical summaries, as
         are necessary to satisfy any requirements imposed by a Regulator upon
         Insurers with respect to the Business Covered. In addition,
         Administrator, upon the reasonable request of Insurers, shall promptly
         provide to Insurers copies of all existing records relating to the
         Reinsured Contracts (including, with respect to records maintained in
         machine readable form, hard copies) that are necessary to satisfy such
         requirements.

7.2      Administrator shall reasonably assist Insurers and cooperate with
         Insurers in doing all things necessary, proper or advisable, in the
         most expeditious manner practicable in connection with any and all
         market conduct or other Regulator examinations relating to the Business
         Covered.

                                       13


                                  ARTICLE VIII

                         OTHER REPORTING AND ACCOUNTING

Commencing on January 1, 2002, Administrator shall assume the reporting and
accounting obligations set forth in this Article VIII. Administrator will
reimburse CGU for the costs of providing such reporting and accounting
obligation services from the Inception Date to January 1, 2002. From January 1,
2002, Administrator shall provide the following:

8.1      Administrator shall timely provide to Insurers and Insurers' designated
         independent auditors such reports and summaries (and, upon request of
         Insurers, detailed supporting records) related to the Business Covered
         as may be reasonably required for use in connection with the
         preparation of Insurer's statutory financial statements to be filed
         with the appropriate Regulators, including, without limitation, (i)
         line of business data for inclusion in Insurers' annual statements, and
         (ii) statistics relating to complaints, in the form of a log suitable
         for inclusion in Insurers' annual statements.

8.2      Administrator shall timely provide to Insurers or Insurers' designated
         independent auditors such reports or summaries (and, upon the request
         of Insurers, detailed supporting records therefor) related to the
         Business Covered as may be reasonably required in connection with the
         preparation in accordance with generally accepted accounting principles
         of Insurer's balance sheets and related statements of income,
         stockholders' equity and cash flows or changes in financial position,
         including, without limitation, the related notes and auditors' report
         thereon and any associated management letter.

8.3      Nothing in this Article 8 shall obligate Administrator to provide
         greater quality or scope of data than is currently being prepared by
         each Insurer, except for such changes as may be mandated by future
         changes in law or regulation.

                                   ARTICLE IX

                        MAINTENANCE OF NON-CLAIM RECORDS

Commencing on the Effective Date, Administrator shall assume responsibility for
maintaining records with respect to the Business Covered accounting, and
reporting and any other category of non-Claim Administrative Services.

9.1      The Administrator shall be entitled to have transferred to it (or as to
         such person as it may direct) on or after the Effective Date the
         Relevant Business Records. If such Records are in the possession of
         another party CGU shall instruct that party to release such Records as
         soon as possible so that the Administrator may be in a

                                       14


         position to provide the Run-off Functions under this Agreement. All
         Records made available to the Administrator either by CGU or any third
         party shall remain the property of CGU (or such third party) at all
         times. The Administrator (or such person as it may direct) shall hold
         the Relevant Business Records as agent on behalf of the relevant
         Insurer. Such records shall be maintained at a location within the
         United States selected by Administrator for this purpose and made known
         to Insurers. Upon expiration of this Agreement, Administrator shall
         transfer the Relevant Business Records to CGU or such person within the
         United States as CGU may direct. Administrator shall be allowed to
         access CGU records in storage to locate relevant insurance and
         reinsurance records and shall reimburse CGU for expenses paid to third
         parties for such access.

                                    ARTICLE X

                                ACCESS TO RECORDS

10.1     The Administrator shall make such Relevant Business Records as are in
         its possession or under its control available to CGU at any time during
         normal office hours for such auditing or any other purposes related to
         the Reinsurance Agreement or this Agreement as CGU may require. CGU
         shall, at its own expense, be entitled to make copies of the Relevant
         Business Records for these purposes. Administrator will provide the
         needed information, including access to claim files and personnel, for
         the purpose of periodically updating actuarial studies of gross
         liabilities.

10.2     The Relevant Business Records shall at all times be open for inspection
         by the Administrator (where such Records are being kept by CGU) and by
         CGU (where such Records are being kept by the Administrator) and (in
         each case) their respective representatives during normal business
         hours and on reasonable notice, for such auditing or other purposes as
         the Administrator or CGU may require. The Administrator shall permit
         CGU and its representatives and CGU shall permit the Administrator and
         its representatives to make copies of such Records. This obligation
         shall survive the expiration of this Agreement and continue for so long
         as the Administrator may have any liability arising under this
         Agreement or the Aggregate Reinsurance Agreement. Administrator shall
         take reasonable steps to maintain the confidentiality of such records.

                                       15


                                   ARTICLE XI

                             COOPERATION BY INSURERS

11.1     Insurers shall cooperate to the extent reasonably possible with
         Administrator and execute and provide such additional documentation as
         may become necessary or appropriate to enable Administrator to fully
         carry out its responsibilities under this Agreement and to effectuate
         the intention of the parties under the Aggregate Reinsurance Agreement,
         the Potomac Reinsurance Agreement and this Agreement.

                                   ARTICLE XII

                                     POWERS

12.1     Each of the parties warrants to the other that:

12.1.1   it has power (whether for itself or (in the case of CGU) as agent for
         any CGU Insurer) to enter into and has duly authorized the execution
         and delivery of this Agreement; and

12.1.2   it has, if and to the extent required or appropriate, obtained all
         requisite regulatory and supervisory consents, and shall maintain all
         requisite regulatory and supervisory consents for the term of this
         Agreement.

                                  ARTICLE XIII

                                 INDEMNIFICATION

13.1     Administrator agrees to indemnify and hold harmless Insurers and each
         of their directors, officers, employees, agents or affiliates (and the
         directors, officers, employees and agents of such affiliates) from any
         and all losses, liabilities, costs, claims, demands, compensatory,
         extra contractual and/or punitive damages, fines, penalties and
         expenses (including reasonable attorneys' fees and expenses)
         (collectively, "Insurer's Losses") resulting in damages not included
         within the definition of Ultimate Net Loss arising out of or caused by:
         (i) any actual or alleged fraud, theft or embezzlement by officers,
         employees or agents of Administrator during the term of this Agreement;
         (ii) the failure, either intentional or unintentional, of Administrator
         to properly perform the services or take the actions required by this
         Agreement, including, without limitation, the failure to properly
         process, evaluate and pay disbursement requests in accordance with the

                                       16


         terms of this Agreement; (iii) any other act of negligence or willful
         misconduct committed by officers, agents or employees of Administrator
         during the term of this Agreement; (iv) any liability of CGU to any
         employee of a subsidiary of CGU operating under the control of the
         Administrator and arising due to any act or omission by the management
         or other employee after the effective date; or (v) any failure of
         Administrator to comply with applicable laws, rules and regulations
         during the term of this Agreement. Nothing herein shall be construed to
         require Administrator to indemnify any Insurer under this Article for
         compensatory, extra contractual and/or punitive damages, fines,
         penalties or expenses arising out of a settlement or judgment of a
         claim of bad faith or failure to exercise good faith in the handling of
         a claim if the claim at issue was handled properly as measured from the
         perspective of a risk neutral professional claims examiner. In the
         event of a dispute between the parties as to the application of the
         foregoing sentence no verdict or court decision concerning the actions
         of the Administrator shall be considered or given any weight whatsoever
         nor, in the event of a claim of bad faith failure to accept a
         settlement offer, shall the ultimate result of the claim be considered,
         it being the intention of the parties that the arbitration panel
         consider this issue de novo from the perspective of a professional
         claims examiner making a decision with the facts and law available at
         the time the decision was made. In the event that the arbitration panel
         shall find that the act or omission of the Administrator was in bad
         faith from the perspective of the professional claims examiner then the
         indemnification under this Article shall not be included in Ultimate
         Net Loss. Nothing herein shall be construed to require Administrator to
         indemnify any Insurer with respect to any act or omission where the
         decision to take or omit such action was with the agreement of CGU.

13.2     Insurers agree to indemnify and hold harmless Administrator and any of
         its directors, officers, employees, agents or affiliates (and the
         directors, officers, employees and agents of such affiliates) from any
         and all losses, liabilities, costs, claims, demands, compensatory,
         extra contractual and/or punitive damages, fines, penalties and
         expenses (including reasonable attorneys' fees and expenses)
         (collectively, "Administrator Losses") arising out of or caused by: (i)
         fraud, theft or embezzlement by officers, employees or agents of
         Insurers during the term of this Agreement; (ii) any other act of
         negligence or willful misconduct committed by officers, agents or
         employees of Insurers during the term of this Agreement; or (iii) any
         failure of Insurers to comply with applicable laws, rules and
         regulations during the term of this Agreement other than any failure on
         the part of Insurers or Administrator caused by the action or inaction
         of Administrator, including when acting in the name or on behalf of
         Insurers, whether or not in compliance with the terms of this
         Agreement. Nothing herein shall be construed to require an Insurer to
         indemnify the Administrator with respect to any act or omission where
         the decision to take or omit such action was with the agreement of
         Administrator.

13.3     In the event that either party hereto asserts a claim for
         indemnification hereunder, such party seeking indemnification (the
         "Indemnified Party") shall give written

                                       17


         notice to the other party (the "Indemnifying Party") specifying the
         facts constituting the basis for, and the amount (if known) of, the
         claim asserted within one year of the date the claim is asserted
         against or should be known by "Indemnified Party".

13.4     If an Indemnified Party asserts, or may in the future seek to assert, a
         claim for indemnification hereunder because of a claim or demand made,
         or an action, proceeding or investigation instituted, by any person not
         a party to this Agreement (a "Third Party Claimant") that may result in
         an Administrator Loss with respect to which Administrator is entitled
         to indemnification pursuant to Section 13.2 hereof or an Insurers Loss
         with respect to which Insurers is entitled to indemnification pursuant
         to Section 13.1 hereof (an "Asserted Liability"), the Indemnified Party
         shall so notify the Indemnifying Party as promptly as practicable, but
         in no event later than 10 Business Days after such Asserted Liability
         is actually known to the Indemnified Party. Failure to deliver notice
         with respect to an Asserted Liability in a timely manner shall not be
         deemed a waiver of the Indemnified Party's right to indemnification for
         Losses in connection with such Asserted Liability but the amount of
         reimbursement to which the Indemnified Party is entitled shall be
         reduced by the amount, if any, by which the Indemnified Party's Losses
         would have been less had such notice been timely delivered.

13.5     The Indemnifying Party shall have the right, upon written notice to the
         Indemnified Party, to investigate, contest, defend or settle the
         Asserted Liability; provided that the Indemnified Party may, at its
         option and at its own expense, participate in the investigation,
         contesting, defense or settlement of any such Asserted Liability
         through representatives and counsel of its own choosing. The failure of
         the Indemnifying Party to respond in writing to proper notice of an
         Asserted Liability within 10 days after receipt thereof shall be deemed
         an election not to defend the same. Unless and until the Indemnifying
         Party elects to defend the Asserted Liability, the Indemnified Party
         shall have the right, at its option and at the Indemnifying Party's
         expense, to do so in such manner as it deems appropriate, including,
         but not limited to, settling such Asserted Liability (after giving
         notice of the settlement to the Indemnifying Party) on such terms as
         the Indemnified Party deems appropriate.

13.6     Except as provided in the immediately preceding sentence, the
         Indemnified Party shall not settle or compromise any Asserted Liability
         for which it seeks indemnification hereunder without the prior written
         consent of the Indemnifying Party (which shall not be unreasonably
         withheld) during the 10 day period specified above.

13.7     The Indemnifying Party shall be entitled to participate in (but not to
         control) the

                                       18


         defense of any Asserted Liability which it has elected, or is deemed to
         have elected, not to defend, with its own counsel and at its own
         expense.

13.8     Except as provided in the first sentence of paragraph 13.5 of this
         Section, the Indemnifying Party shall bear all reasonable costs of
         defending any Asserted Liability and shall indemnify and hold the
         Indemnified Party harmless against and from all costs, fees and
         expenses incurred in connection with defending such Asserted Liability.

13.9     Administrator and Insurers shall make mutually available to each other
         all relevant information in their possession relating to any Asserted
         Liability (except to the extent that such action would result in a loss
         of attorney-client privilege) and shall cooperate with each other in
         the defense thereof.

13.10    The provisions of this Article XIII shall survive the termination of
         the Agreement for a period of one year.

                                   ARTICLE XIV

                           DURATION; EARLY TERMINATION

This Article shall have no application to expirations under Article XXI.

14.1     This Agreement shall commence on the date of its execution and continue
         with respect to each Reinsured Contract until no further Run-Off
         Services in respect of such Reinsured Contract is required, unless it
         is earlier terminated as provided herein.

14.2     This Agreement is subject to immediate termination at the option of
         Insurers, upon written notice to Administrator, on the occurrence of
         any of the following events:

14.2.1   A voluntary or involuntary proceeding is commenced in any state by or
         against the Administrator for the purpose of conserving, rehabilitating
         or liquidating Administrator, or Administrator shall lose its authority
         to perform services hereunder;

14.2.2   There is a material breach by Administrator of any term or condition of
         this Agreement, that is not cured by Administrator within 90 days of
         receipt of written notice from Insurers of such breach or act provided
         that in the event of a dispute between the parties as to whether there
         is a material breach, said 90 days shall be tolled from the time of a
         demand for arbitration until issuance of a final judgment of an
         arbitration panel; or

                                       19


14.2.3   Administrator is unable to perform the services (other than the breach
         of this Agreement or the Aggregate Reinsurance Agreement by any CGU
         Insurer) required under this Agreement for a period of 90 consecutive
         days for any reason provided that in the event of a dispute between the
         parties as to whether Administrator is unable to perform the services,
         said 90 days shall be tolled from the time of a demand for arbitration
         until issuance of a final judgment of an arbitration panel.

14.3     This Agreement may be terminated at any time upon the mutual written
         consent of the parties hereto, which writing shall state the effective
         date of termination.

14.4     In the event that this Agreement is terminated under Section 14.2,
         Administrator shall select a third-party administrator to perform the
         services required by this Agreement. Insurers shall have the right to
         approve any such administrator selected by Administrator, but such
         approval will not unreasonably be withheld. If Administrator fails to
         select an administrator pursuant to this Section, Insurers shall select
         such an administrator. In either case, Administrator shall pay all fees
         and charges imposed by the selected administrator and the reasonable
         costs of Insurers in the transition of the performance of the services
         required under this Agreement to such administrator.

14.5     In the event that this Agreement is terminated under Sections 14.2,
         Administrator shall cooperate fully in the transfer of services and the
         books and records maintained by Administrator pursuant to this
         Agreement.

                                   ARTICLE XV

                               RESTRICTIONS ON CGU

15.1     With effect from the Inception Date and in relation to the Business

         obligations hereunder by such other party hereunder. Failure on the
         part of any party to complain of any act or failure to act of any other

         return receipt requested, of its intention to arbitrate and of its
         appointment of an arbitrator in accordance with Section 23.3.

23.2     COMPOSITION OF PANEL. Unless the parties agree upon a single arbitrator
         within fifteen (15) days after the receipt of notice of intention to
         arbitrate, all disputes shall be submitted to an arbitration panel
         composed of two arbitrators and an umpire, chosen in accordance with
         Sections 23.3 and 23.4.

23.3     APPOINTMENT OF ARBITRATORS. The members of the arbitration panel shall

         insurance or reinsurance companies. The party requesting arbitration
         (hereinafter referred to as the "claimant") shall appoint an arbitrator
         and give written notice thereof, by registered or certified mail,
         return receipt requested, to the other party (hereinafter referred to
         as the "respondent") together with its notice of intention to

         of intention to arbitrate, such arbitrator shall be appointed by the
         President of the American Arbitration Association, and shall then,
         together with the arbitrator appointed by the claimant, choose an
         umpire as provided in Section 23.3.

         umpire.

                                       26


23.7     PROCEDURE GOVERNING ARBITRATION. All proceedings before the panel shall
         be informal and the panel shall not be bound by the formal rules of
         evidence. The panel shall have the power to fix all procedural rules

         panel shall give due consideration to the custom and usage of the

         parties as reflected in this Agreement.

         within sixty (60) days after termination of the proceeding, which
         decision shall be in writing. The decision of the majority of the panel
         shall be final and binding on the parties to the proceeding.

         party shall bear the expense of its own arbitrator and its own
         witnesses and shall jointly and equally bear with the other party the
         expense of the umpire and the arbitration.
