with such accounts.

                                  ARTICLE VII

                          INABILITY TO PERFORM SERVICES

            Section 7.1 Inability to Perform Services. In the event that
Administrator shall be unable to perform any Administrative Service for a period
that could reasonably be expected to exceed ninety (90) days, Administrator and
LaSalle Re shall mutually agree on alternative means of providing such services.
If either party shall fail to cooperate in identifying alternative means for the
provision of the Administrative Services, the other party may procure such
Administrative Services for the Reinsured Contracts and Reinsured Liabilities by
commercially reasonable means. Administrator shall be solely responsible for all
costs incurred in restoring Administrative Services which have not been provided
due to its failure to adhere to its obligations under this Agreement.
Notwithstanding the foregoing, if Administrator is unable to provide the data
necessary for any monthly closing activities, Administrator will use its
reasonable best efforts to provide estimates of such data.

                                  ARTICLE VIII

agree to an appropriate response, including which party should respond, to any
investigation or proceeding from or before any Governmental Entity relating to
the Reinsured Contracts or the Reinsured Liabilities and the parties hereby
agree to cooperate and coordinate in resolving any and all Material Regulatory
Proceedings. Neither LaSalle Re nor Administrator shall have the authority


                                       8


to institute, prosecute, defend or maintain any legal or regulatory proceedings
on behalf of the other party without the prior written consent of such other
party.

            Section 8.2 Defense of Litigation. Administrator shall defend, at
its own expense and in the name of LaSalle Re when necessary, any action brought
in connection with any Reinsured Contract or relating to any Reinsured
Liability, provided, however, Administrator shall not be required to defend
Excluded Liabilities, except as set forth in Section 3.1 hereof. LaSalle Re
shall have the right, at its own expense, to engage its own separate legal
representation and to fully participate in the defense of any litigation with
respect to the Reinsured Contracts or the Reinsured Liabilities in which LaSalle
Re is named as a party without waving any rights to indemnification it may have
under Article XI hereof; provided, however, that Administrator shall have the
exclusive authority to control such litigation, and to settle any litigation if
(i) Administrator pays all settlement amounts with respect thereto, (ii) the
settlement does not involve any restriction or condition on LaSalle Re's
business other than exclusively to the Reinsured Contracts transferred pursuant
to the Transfer and Purchase Agreement and (iii) Administrator obtains a
complete and unqualified release for LaSalle Re with respect to such litigation.

            Section 8.3 Communications Regarding Certain Matters. LaSalle Re
shall promptly (i) notify Administrator in writing if it receives any
information or correspondence with respect to any suit, claim, action or
proceeding relating to the Reinsured Contracts or the Reinsured Liabilities, or
any written communication threatening any of the foregoing and (ii) forward to
Administrator any documents it receives relating to any of the matters referred
to in clause (i) of this Section 8.3.

                                   ARTICLE IX

                              DURATION; TERMINATION

            Section 9.1 Duration. This Administrative Services Agreement shall
become effective as of the date hereof and continue until a date which is the
earlier of (A) a date which is the later of (i) the date on which none of the
Reinsured Contracts remains in force; or (ii) the date on which LaSalle Re has
no further Reinsured Liabilities; or (B) the date on which this Administrative
Services Agreement is terminated according to the provisions of Section 9.2
hereof.

            Section 9.2 Termination.

                  (a) This Administrative Services Agreement may be terminated
at any time upon the mutual written consent of the parties hereto, which writing
shall state the effective date and relevant terms of termination.

                  (b) Upon any termination of this Administration Services
Agreement, such party shall retain its right to bring actions for, and receive
damages to, which it may be entitled under Applicable Law.

Re and Administrator have taken and will continue to take reasonable actions to
ensure such information is not made available to the public. LaSalle Re and
Administrator further agree that they will not at any time (during the term
hereof or thereafter) disclose to any Person (except LaSalle Re or Administrator
and their Affiliates and the officers, directors, employees, agents and
representatives of LaSalle Re and Administrator and their Affiliates who require
such information in order to perform their duties in connection with the
services provided hereunder), directly or indirectly, or make any use of, for

Agreement, this Administrative Services Agreement or the Retrocession Agreement,

the Reinsured Liabilities or the business affairs of LaSalle Re or
Administrator, including the identity of and/or the compensation arrangements
with, any Affiliates and Subsidiaries of LaSalle Re and Administrator, so long
as such information remains confidential.

            Section 10.2 Disclosure. Administrator or LaSalle Re may disclose
confidential information in the following circumstances (or as otherwise
provided by the provisions of this Administrative Services Agreement):

      only to the extent that is required by such court order or formal
      disclosure request;

                  (ii) if a proper request is made by any regulatory authority

      only to the extent that is required by such regulatory authority;

                  (iii) at the proper request of LaSalle Re or Contractholder or
      his/her legal representative; provided, however, that such disclosure
      shall be limited only to the extent that is reasonably necessary to
      satisfy such a request; or

                  (iv) as otherwise required by Applicable Law.

                                   ARTICLE XI

indemnifies Administrator and its Affiliates and its and their respective
officers, directors, employees, agents


                                       10


and representative against, and agrees to hold each of them harmless from any

this Administrative Services Agreement or breach thereof, whether such dispute
arises before or after termination of this Administrative Services Agreement,
such dispute, upon the written request of either party, shall be submitted to
three arbitrators, one to be chosen by each party, and the third by the two so
chosen. If either party refuses or neglects to appoint an arbitrator within
thirty (30) days after the receipt of written notice from the other party
requesting it to do so, the requesting party may appoint two arbitrators. If the
two arbitrators fail to agree in the selection of a third arbitrator within
thirty (30) days of their appointment, either of the parties may apply to the
Bermuda Supreme Court for the appointment of the third arbitrator pursuant to
Section 15(1)(c) of the Bermuda Arbitration Act 1986 and in such case the person
so appointed shall be deemed and shall act as the third arbitrator. All
arbitrators shall be active or retired disinterested officers of insurance or
reinsurance companies or Underwriters at Lloyd's, London not under the control
of either party to this Administrative Services Agreement.

                  (b) The arbitrators shall be relieved of all judicial
formalities and may abstain from following the strict rules of evidence. Each
party shall submit its case to the arbitrators within thirty days of the
appointment of the third arbitrator.

with the parties hereto, shall be final and binding on both parties. Judgment
may be entered upon the final decision of the arbitrators in any court having
jurisdiction. Each party shall bear the expense of its own arbitrator and shall
jointly and equally bear with the other party the expense of the third
arbitrator and of the arbitration. Said arbitration shall take place in Bermuda
unless some other place is mutually agreed upon by the parties to this
Administrative Services Agreement, subject to the provisions of the Bermuda
Arbitration Act 1986 or any re-enactment or statutory modification thereof.
