                                           [X] Multi-Currency Account
                                                         as hereinafter defined.

          a.   A Single Currency Account shall be invested 100% in the Base
               Currency as defined in Section I.2.a. Securities denominated in
               or linked to other currencies are permitted only at the direction
               of the Client.

          b.   A Hedged Currency Account shall be invested in securities
               denominated in or linked to any currency provided, however, that
               foreign exchange contracts, futures and/or options are executed
               to reduce the net non-Base Currency exposure to less than 5% of
               the Portfolio Market Value.

          c.   A Multi-Currency Account shall be invested in securities
               denominated in or linked to any currency. Whether or not foreign
               exchange contracts, futures and or options are permitted in
               Section I.2., the non-Base Currency exposure of the Portfolio
               shall not exceed 20.0% of the Portfolio Market Value. The net
               non-Base Currency exposure shall not exceed 20.0 % of the
               Portfolio Market Value

               Unless permitted in Section I.2., Foreign Exchange Contracts
               shall not be executed for a Multi-Currency Account except for the
               acquisition or disposition of securities or for the conversion of
               coupon/dividend receipts to the Portfolio Base Currency; no
               hedging or speculative currency transactions are permitted.

          All country limits are percent of Portfolio MARKET Value on date of
          purchase and refer to the country of issuer or guarantor. In the case
          of banking institutions, the country of a full branch shall be deemed
          to be the domicile of the head office. Country exposures shall not
          exceed the greater of the country limit or U.S. $5,000,000 equivalent

     3.   Issuer Limits

          a.   Except in the case of Supranational, Sovereign, and Sovereign -
               supported issues, where the limits under IV.2 above apply, the
               securities of one issuer should not exceed the greater of 10.0%
               of the Portfolio MARKET Value or U.S. $5,000,000 at time of
               purchase.

     4.   Issue Limits

          a.   In the case of fixed income securities, no holding should exceed
               the greater of 10% of the amount outstanding or U.S. $5,000,000
               nominal at the time of purchase.

     5.   Maturity Limits

          a.   In the case of fixed income securities, no individual security
               shall have a remaining MODIFIED DURATION greater than EIGHT
               YEARS.

          b.   In the case of money market securities, no individual security
               shall have a remaining MATURITY greater than TEN YEARS,
               notwithstanding the frequency of any rate reset provision of the
               security.

          c.   The Portfolio shall maintain a target WEIGHTED AVERAGE MODIFIED
               DURATION of between approximately 1.25 AND 3.75 YEARS. For
               purposes of this calculation only, the maturity of a floating
               rate security is deemed to be its next succeeding reset date.

     6.   US Securities

          The purchase of US securities IS permitted.

     7.   Credit Risk

          a.   All securities purchased for the Portfolio which carry a long
               term rating by either Standard & Poor's or Moody's shall have a
               rating of AA- or AA3 or better at the time of purchase.
               Notwithstanding the foregoing, securities may be purchased for
               the Portfolio which have ratings of A- or A3 or better provided
               that, in aggregate, they do not constitute more than 25% of the
               Portfolio MARKET Value. (Securities which are not so rated at the
               time of intended purchase shall not be permitted except on a case
               by case approval of the Client.)

               All securities purchased for the Portfolio which carry a short
               term rating by either Standard & Poor's or Moody's shall have a
               rating of A-1 or P-1 or better at the time of purchase.
               Notwithstanding the foregoing, securities may be purchased for
               the Portfolio which have ratings of A-2 or P-2 or better provided
               that, in aggregate, they do not constitute more than 25% of the
               Portfolio MARKET Value. (Securities which are not so rated at the
               time of intended purchase shall not be permitted except on a case
               by case approval of the Client.)

          b.   Unrated securities ARE permitted. The unrated securities shall
               have credit quality at the time of purchase, as determined in
               good faith by the Company, equivalent to other permitted
               securities which are rated as in IV.7.a. The Client shall be
               notified at least quarterly as to the composition and status of
               the unrated securities held in the Portfolio.

                                      -17-
<PAGE>   4
          c.   A security purchased either in accordance with Section IV.7.a.
               which receives a downwardly revised rating or in accordance with
               Section IV.7.b. which receives a newly established rating that in
               either case would make such security ineligible for further
               purchase remains a permitted security to the extent of the then
               current holdings.

          d.   Private placements ARE permitted. Any private placements
               purchased for the Portfolio shall be marketable securities. This
               permission is specifically intended to allow the purchase of
               unlisted securities.

          [ ]  Additional detail is attached as Credit Risk Schedule.

     8.   Realized Gains/Losses

          Net realized capital gains and losses should be minimized. (For
          example: To the extent fixed income assets are permitted, bond switch
          activity to enhance returns is encouraged, but should not become
          excessive and should be undertaken within the context of minimizing
          net gains and losses).

V.   GENERAL EQUITY GUIDELINES

     1.   The U.S. Equity portion of the Portfolio seeks to replicate the
          aggregate price and yield performance of the Standard & Poor's 500
          Composite Stock Price Index (the "S&P 500 Index"), an index which
          emphasizes large capitalization companies in the United States.

     2.   The Global Equity portion of the Portfolio seeks to outperform the
          total return of the MSCI World All Countries TR Free (USD) Index.

VI.  FEES

     The fee schedule will be calculated as follows: 0.35% per annum on the
     first $100 MILLION U.S. dollars, or equivalent of Portfolio MARKET value;
     0.25 % per annum on the next $100 MILLION; and 0.15 % per annum on any
     amount exceeding $200 MILLION.

     The fees will be calculated based on the previous month end MARKET value of
     the portfolio (including accrued interest) and are payable MONTHLY IN
     ARREARS. The fees shall be reduced proportionally for any part of a period
     in which this Agreement is not in full effect.

by and among IPCRe Limited, a Bermuda corporation (the "Borrower"), Bank One, NA
(formerly known as The First National Bank of Chicago), individually and as

                                    RECITALS

         A.       The Borrower, the Agent and the Lenders are party to that
certain Credit Agreement dated as of June 30, 1998 (the "Credit Agreement").
Unless otherwise specified herein, capitalized terms used in this Amendment
shall have the meanings ascribed to them by the Credit Agreement.

         B.       The Borrower, the Agent and the undersigned Lenders wish to
amend the Credit Agreement on the terms and conditions set forth below.

         NOW, THEREFORE, in consideration of the mutual execution hereof and
other good and valuable consideration, the parties hereto agree as follows:

         1.       Amendments to Credit Agreement. Upon the "Effective Date" (as
defined below), the Credit Agreement shall be amended as follows:

                  (a)      The definition of "Commitment" in Article I of the
Credit Agreement shall be amended and restated in its entirety to read as
follows:

                  "Commitment" means, for each Lender, the obligation of such
         Lender to make Loans not exceeding the amount set forth opposite its
         name on Schedule I hereto or as set forth in any Notice of Assignment
         relating to any assignment that has become effective pursuant to
         Section 12.3.2, as such amount may be modified from time to time
         pursuant to the terms hereof.

                  (b)      Section 6.14(v) of the Credit Agreement shall be
amended and restated in its entirety to read as follows:

                  (v)      Investments by the Borrower in equity securities in
         an aggregate amount not to exceed 25% of the Consolidated Net Worth of
         the Borrower and its Subsidiaries; provided, that no single Investment
         in equity securities (other than an Investment in a mutual fund) shall
         be in an amount in excess of 5% of the Consolidated Net Worth of the
         Borrower and its Subsidiaries; provided, further, that no single
         Investment in a mutual fund shall be in an amount in excess of 15% of
         the Consolidated Net Worth of the Borrower and its Subsidiaries.

                  (c)      The Credit Agreement shall be amended by adding
thereto a new Schedule I in the form of Schedule I attached hereto and made a
part hereof.

         2.       Representations and Warranties of the Borrower. The Borrower
represents and warrants that:

                  (a)      The execution, delivery and performance by the
Borrower of this Amendment have been duly authorized by all necessary corporate
action and that this Amendment is a legal, valid and binding obligation of the
Borrower enforceable against the Borrower in accordance with its terms, except
as the enforcement thereof may be subject to the effect of any applicable
bankruptcy, insolvency, reorganization, moratorium or similar law affecting
creditors' rights generally;

                  (b)      Each of the representations and warranties contained
in the Credit Agreement is true and correct in all material respects on and as
of the date hereof as if made on the date hereof, except to the extent any such
representation or warranty is stated to relate solely to an earlier date, in
which case such representation or warranty shall have been true and correct on
and as of such earlier date;

                  (c)      After giving effect to this Amendment, no Default or
Unmatured Default has occurred and is continuing.

         3.       Effective Date. Section 1 of this Amendment shall become
effective upon satisfaction of the following conditions:

                  (a)      Executed Amendment. Receipt by the Agent of duly

                  (b)      Mandatory Prepayment. Receipt by the Agent of a
prepayment in the amount, if any, by which the aggregate principal amount of the

                  (c)      Miscellaneous. Receipt by the Agent of such other

Agreement and the other Loan Documents shall remain in full force and effect and
are hereby ratified and confirmed.

                  (b)      The execution, delivery and effectiveness of this
Amendment shall not operate as a waiver of any right, power or remedy of the
Agent or any Lender under the Credit Agreement or any Loan Document, nor
constitute a waiver of any provision of the Credit Agreement or any Loan
Document, except as specifically set forth herein. Upon the effectiveness of
this Amendment, each reference in the Credit Agreement to "this Agreement,"
"hereunder," "hereof," "herein" or words of similar import shall mean and be a
reference to the Credit Agreement as amended hereby.

         5.       GOVERNING LAW. THIS AMENDMENT SHALL BE GOVERNED BY AND
CONSTRUED IN ACCORDANCE WITH THE INTERNAL LAWS (AS OPPOSED TO CONFLICTS OF LAWS

Amendment for any other purposes.

         7.       Counterparts. This Amendment may be executed in any number of
counterparts, each of which when so executed shall be deemed an original but all
such counterparts shall constitute one and the same instrument.
