Exhibit 4.2.5 FOURTH AMENDMENT TO THE CREDIT AGREEMENT This Fourth Amendment ("Fourth Amendment"), dated as of September 29, 1999, is among ENHANCE FINANCIAL SERVICES GROUP INC., a corporation duly organized and validly existing under the laws of the State of New York (together with its successors and assigns, the "COMPANY"); each of the lenders that is a signatory hereto (together with its successors and assigns, individually, a "BANK", and, collectively, the "BANKS"); and FLEET NATIONAL BANK, as Swingline Bank (in such capacity, together with its successors and permitted assigns in such capacity, the "SWINGLINE BANK") and as agent for the Banks (in such capacity, together with its successors in such capacity, the "AGENT"). The Company, the Banks, the Swingline Bank and the Agent are parties to a Credit Agreement dated as of June 30, 1998, which Credit Agreement was amended and restated in its entirety by the Third Amendment to the Credit Agreement dated as of June 29, 1999 (as so amended and restated and in effect on the date hereof, the "CREDIT AGREEMENT"). The Company has requested the Banks to increase the commitment of each Bank to make revolving loans and to amend the covenant in the Credit Agreement relating to the Company's incurrence or creation of additional indebtedness. The Banks are in agreement with such request upon certain terms and conditions. Accordingly, the parties hereto hereby agree as follows: Section 1. DEFINITIONS. Except as otherwise defined in this Fourth Amendment, terms defined in the Credit Agreement are used herein as defined therein. Section 2. AMENDMENTS. Subject to the satisfaction of the conditions precedent specified in Section 3 below, but effective as of the date hereof, the Credit Agreement shall be amended as follows: (a) Section 1.01 (CERTAIN DEFINED TERMS) is amended as follows: (i) by deleting the definition of "Applicable Margin" and substituting therefor the following: "APPLICABLE MARGIN" shall mean: (a) 1.50% per annum with respect to Revolving Credit Loans and Term Loans made, Converted or Continued during the Increased Rate Period that are Base Rate Loans, and 0% per annum for all other Revolving Credit Loans and Term Loans that are Base Rate Loans; and (b) with respect to (i) Revolving Credit Loans and Term Loans that are Eurodollar Loans or (ii) with respect to facility fees payable hereunder, the applicable percentage per annum set forth below under the caption "Eurodollar Spread" or "Facility Fee Rate", as the case may be, based upon the ratings by S&P and Moody's applicable on such date to the Index Debt: - -------------------------------------------------------------------------------- Eurodollar Spread -------------------------------- Index Debt Revolving Facility Fee Rating: Credit Loan(1) Term Loan Rate - -------------------------------------------------------------------------------- Level 1 0.210% 0.310% 0.070% - -------------------------------------------------------------------------------- Level 2 0.250% 0.350% 0.080% - -------------------------------------------------------------------------------- Level 3 0.290% 0.390% 0.090% - -------------------------------------------------------------------------------- Level 4 0.325% 0.425% 0.105% - -------------------------------------------------------------------------------- Level 5 0.355% 0.455% 0.125% - -------------------------------------------------------------------------------- (1) During any period that the aggregate outstanding principal amount of Revolving Credit Loans, Competitive Loans and Swingline Loans equals or exceeds 33 1/3% of the aggregate Commitments of the Banks, the Eurodollar Spread for Revolving Credit Loans shall be increased by .100% above the percentages set forth in the above grid for each of the Index Debt Rating Levels. In addition to any increases resulting from the application of the provisions of the preceding sentence, the Eurodollar Spread for all Revolving Credit Loans made, Converted or Continued during the Increased Rate Period shall be increased by an additional 1.500% per annum above the percentages set forth in the above grid for each of the Index Debt Rating Levels. - -------------------------------------------------------------------------------- For purposes of determining the applicable Index Debt Rating (except for split ratings of more than one equivalent level as provided for below): (a) Level 1 shall be deemed to be applicable if (i) no Event of Default shall have occurred and be continuing and (ii) the Index Debt is rated AA or higher by S&P or Aa2 or higher by Moody's; (b) Level 2 shall be deemed to be applicable if (i) no Event of Default shall have occurred and be continuing, (ii) Level 1 is not applicable and (iii) the Index Debt is rated A or higher by S&P OR A2 or higher by Moody's; (c) Level 3 shall be deemed to be applicable if (i) no Event of Default shall have occurred and be continuing, (ii) neither Level 1 nor Level 2 is applicable and (iii) the Index Debt is rated A- or higher by S&P OR A3 or higher by Moody's; (d) Level 4 shall be deemed to be applicable if (i) no Event of Default shall have occurred and be continuing, (ii) neither Level 1, Level 2 nor Level 3 is applicable and (iii) the Index Debt is rated BBB+ or higher by S&P OR Baa1 or higher by Moody's; and (e) Level 5 shall be deemed to be applicable if no other Level is applicable. If S&P or Moody's shall not have in effect a rating for the Index Debt (other than by reason of the circumstances referred to in the last sentence of this definition), then S&P shall be deemed to have established a rating in Level 5. If the rating for the Index Debt of S&P and Moody's is split by more than one equivalent rating level, the Index Debt Rating shall be deemed to be at that Level corresponding to the rating that is one level higher than the lower of the two ratings. If the rating established or deemed to have been established by S&P or Moody's for the Index Debt shall be changed (other than as a result of a change in the rating system of S&P or Moody's), such change shall be effective as of the -2- date on which it is first announced by S&P or Moody's, as the case may be. Each change in the Applicable Margin shall apply during the period commencing on the effective date of such change and ending on the date immediately preceding the effective date of the next such change. If the rating system of S&P or Moody's shall change, or if S&P or Moody's shall cease to be in the business of rating corporate debt obligations, the Company and the Banks shall negotiate in good faith to amend this definition to reflect such changed rating system or the unavailability of ratings from such rating agency and, pending the effectiveness of any such amendment, the Applicable Margin shall be determined by reference to the rating most recently in effect prior to such change or cessation. (ii) by deleting the definition of "Commitment" and substituting therefor the following: "COMMITMENT" shall mean, as to each Bank, the obligation of such Bank to make Loans in an aggregate amount not exceeding the amounts and for the time periods set opposite such Bank's name under the caption "Commitment" on the signature pages of the Fourth Amendment (as the same may be reduced at any time or from time to time pursuant to Section 2.03 hereof). (iii) by adding the following new definitions: "FOURTH AMENDMENT" shall mean the Fourth Amendment to the Credit Agreement dated as of September 29, 1999 among the Company, the Banks signatory thereto, the Swingline Bank and the Agent. "INCREASED COMMITMENT PERIOD" shall mean the period from the Amendment Effective Date (as defined in the Fourth Amendment) to the earlier of (a) March 31, 2000 or (b) ten (10) days after the date the Company issues any shares of the capital stock of any class in the public or private market other than in connection with (i) the Company's employee or director incentive or stock option plans (including, without limitation, the exercise of employee or director stock options issued thereunder) or the Company's Director Stock Ownership Plan or (ii) any acquisition by the Company or any of its Subsidiaries of any business otherwise permitted by this Agreement, the consideration for which is, in whole or in part, shares of the capital stock of such class. "INCREASED RATE PERIOD" shall mean the period from December 15, 1999 to January 17, 2000. (b) Subsection (a) of Section 3.01 (REPAYMENT OF LOANS) is deleted and replaced with the following: "(a) The Company hereby promises to pay the Administrative Agent for account of each Bank (i) the outstanding principal amount of each of such Bank's Revolving Credit Loans, and each Revolving Credit Loan shall mature, on the Commitment Termination Date; (ii) the outstanding principal amount of each -3- Competitive Loan, and each Competitive Loan shall mature, on the last day of the Interest Period applicable to such Loan; and (iii) on the first Business Day after the Increased Commitment Period, such principal amount of each Bank's Revolving Loans as may be necessary so that after such repayment, the aggregate unpaid principal amount of all Loans does not exceed the Commitment as automatically reduced upon the expiration of the Increased Commitment Period. (c) Subsection (d) of Section 8.07 (INDEBTEDNESS) is deleted and replaced with the following: "(d) additional Indebtedness of the Company and its Material Subsidiaries provided that on the date such Indebtedness is incurred and after giving effect thereto and to the concurrent retirement of any other Indebtedness of the Company and its Material Subsidiaries, total consolidated Indebtedness of the Company and its Subsidiaries (including Indebtedness created or incurred under any other subsection of this Section 8.07) does not exceed 25% of Total Capitalization or 50% of the sum of (i) Combined Statutory Surplus and (ii) the contingency reserves reported by each Insurance Subsidiary of Enhance Investment in its most recent Statutory Statement. Section 3. CONDITIONS PRECEDENT. This Fourth Amendment shall take effect from the first day (the "Amendment Effective Date") that the Agent shall have received counterparts hereof signed by the Company, each of the Banks identified on the signature pages of this Fourth Amendment, the Swingline Bank and the Agent, and each of the conditions set forth in this Section 3 has been waived by each Bank and the Agent or met: (a) The Agent shall have received from the Company a certificate of a senior officer to the Company, dated the Amendment Effective Date, stating that: (i) the representations and warranties contained in Section 7 of the Credit Agreement are correct on and as of the date of such certificate as though made on and as of such date (or, if such representation or warranty is expressly stated to have been made as of a specific date, as of such specific date); and (ii) no Event of Default or Default has occurred and is continuing or would result from the signing of the Fourth Amendment or the transactions contemplated thereby, in each case taking into account the effect of the amendment to Section 8.07(d) being made by this Fourth Amendment.
