LINE OF CREDIT AGREEMENT THIS LINE OF CREDIT AGREEMENT (the "Agreement") is made and entered into this 15th day of December, 1994 by and between SANWA BANK CALIFORNIA (the "Bank") and ZENITH NATIONAL INSURANCE CORP. (the "Borrower"). SECTION I AGREEMENT TO LEND 1.01 COMMITMENT TO LEND. Subject to the terms and conditions of this Agreement and so long as no Event of Default occurs, the Bank agrees to extend to the Borrower the credit accommodations that follow. 1.02 LINE OF CREDIT. The Bank agrees to make loans and advances ("Advances") to the Borrower, upon the Borrower's telephonic, written or facsimile request therefor made prior to the Expiration Date, up to a total principal amount from time to time outstanding of not more than $30,000,000.00 (the "Line of Credit"); provided that any sums repaid under the Line of Credit may be reborrowed. The Borrower may permanently reduce the amount of the Line of Credit by notice in writing to the Bank provided such reductions are in increments of $1,000,000.00. A. PURPOSE. Advances made under the Line of Credit shall be used for general corporate purposes. B. LINE ACCOUNT. The Bank shall maintain on its books a record of account in which the Bank shall make entries for each Advance and such other debits and credits as shall be appropriate in connection with the Line of Credit (the "Line Account"). The Bank shall provide the Borrower with a monthly statement of the Borrower's Line Account, which statement shall be considered to be correct and conclusively binding on the Borrower unless the Borrower notifies the Bank to the contrary within 30 days after the Borrower's receipt of any such statement which it deems to be incorrect. C. INTEREST. Interest shall accrue from the date of each Advance under the Line of Credit at one of the following rates, as quoted by the Bank and as elected by the Borrower pursuant to paragraph 1.02F or 1.02G below: 1. REFERENCE RATE ADVANCES. A variable rate equivalent to an index for a variable interest rate which is quoted, published or announced from time to time by the Bank as its reference rate and as to which loans may be made by the Bank at, below or above such reference rate (the "Reference Rate") minus .25% per annum (the "Variable Rate"). Interest shall be adjusted concurrently with any change in the Reference Rate. An Advance based upon the Variable Rate is hereinafter referred to as a "Reference Rate Advance." Each such Reference Rate Advance shall be a minimum of $100,000. 2. FED FUNDS ADVANCES. A variable rate per annum (the "Federal Funds Rate"), for each day in which the Advance is based upon the Federal Funds Rate (a "Fed Funds Advance"), equivalent to 1.00% in excess of the interest rate equal to the weighted average of the rates on overnight Federal funds transactions with members of the Federal Reserve System, quoted to the Bank on such day by Federal funds brokers of recognized standing which are selected by the Bank in its sole discretion or, if such day is not a business day, for the immediately preceding business day. With respect to this section 1.02(C)(2), a business day means a day in which banks are open generally in Chicago and New York for the conduct of substantially all of their commercial lending activities. Fed Funds Advances must be in the minimum amount of $250,000.00. 3. EURODOLLAR ADVANCES. A fixed rate quoted by the Bank for 30, 60, 90, 120, 180 or 360 days or for such other period of time that the Bank may quote and offer (provided that any such period of time does not extend beyond the Expiration Date) [the "Interest Period"] for Advances in the minimum amount of $250,000.00. Such interest rate shall be a percentage equivalent to .75% in excess of the Bank's Eurodollar Rate which is that rate determined by the Bank's Treasury Desk as being the approximate rate at which the Bank could purchase offshore U.S. dollar deposits in an amount approximately equal to the amount of the relevant Advance and for a period of time approximately equal to the relevant Interest Period (adjusted for any and all assessments, surcharges and reserve requirements pertaining to the purchase by the Bank of such U.S. dollar deposits) [the "Eurodollar Rate"]. An Advance based upon the Eurodollar Rate is hereinafter referred to as a "Eurodollar Advance." Interest on any advance shall be computed on the basis of 360 days per year, but charged on the actual number of days elapsed. -1- Interest on any Reference Rate Advance or Fed Funds Advance (hereinafter referred to as "Variable Rate Advances") shall be paid in monthly installments commencing on the last day of the month following the date of the first such Advance and continuing on the last day of each month thereafter. Interest on any Eurodollar Advance with an Interest Period of 90 or less days shall be paid on the last day of the Interest Period pertaining to such Eurodollar Rate Advance. Interest on any Eurodollar Rate Advance with an Interest Period in excess of 90 days shall be paid quarterly (i.e., on the last day of each 90 day period occurring in such Interest Period) and on the last day of the Interest Period pertaining to such Eurodollar Rate Advance. If interest is not paid as and when it is due, it shall be added to the principal, become and be treated as a part thereof, and shall thereafter bear like interest. D. PRINCIPAL. Unless sooner due in accordance with the terms of this Agreement, the Borrower hereby promises and agrees to pay to the Bank in full the aggregate unpaid principal amount of all Advances then outstanding, together with all accrued and unpaid interest thereon on the Expiration Date. E. EXPIRATION OF LINE OF CREDIT. Unless earlier terminated in accordance with the terms of this Agreement, the Bank's commitment to make Advances to the Borrower hereunder shall automatically expire on November 30, 1999 (the "Expiration Date"). F. NOTICE OF BORROWING. Upon telephonic, written or facsimile notice which shall be received by the Bank at or before 10:00 a.m. (California time) on a business day, the Borrower may borrow under the Line of Credit by requesting: 1. A VARIABLE RATE ADVANCE. A Variable Rate Advance may be made on the day notice is received by the Bank; provided, however, that if the Bank shall not have received notice at or before 11:00 a.m. on the day such Advance is requested to be made, such Variable Rate Advance may, at the Bank's option, be made on the next business day. 2. A EURODOLLAR RATE ADVANCE. Notice of any Eurodollar Rate Advance shall be received by the Bank no later than two business days prior to the day (which shall be a business day) on which the Borrower requests such Eurodollar Rate Advance to be made. G. NOTICE OF ELECTION TO ADJUST INTEREST RATE. Upon telephonic, written or facsimile notice which shall be received by the Bank at or before 10:00 a.m. (California time) on a business day, the Borrower may elect: 1. That interest on a Variable Rate Advance, which continues to remain a Variable Rate Advance, shall accrue at the sole discretion of the Borrower at either the Federal Funds Rate or at the Variable Rate; 2. That interest on a Variable Rate Advance shall be adjusted to accrue at the Eurodollar Rate; provided, however, that such notice shall be received by the Bank no later than two business days prior to the day (which shall be a business day) on which the Borrower requests that interest be adjusted to accrue at the Eurodollar Rate. 3. That interest on a Eurodollar Rate Advance shall continue to accrue at a newly quoted Eurodollar Rate or shall be adjusted to commence to accrue at the Variable Rate or the Federal Funds Rate; provided, however, that such notice shall be received by the Bank no later than two business days prior to the last day of the Interest Period pertaining to such Eurodollar Rate Advance. If the Bank shall not have received notice (as prescribed herein) of the Borrower's election that interest on any Eurodollar Rate Advance shall continue to accrue at the newly quoted Eurodollar Rate, the Borrower shall be deemed to have elected that interest thereon shall be adjusted to accrue at the Variable Rate upon the expiration of the Interest Period pertaining to such Advance. H. PREPAYMENT. The Borrower may prepay any Advance in whole or in part, at any time and without penalty, provided, however, that: (i) any partial prepayment shall first be applied to accrued and unpaid interest and next to the outstanding principal balance; and (ii) during any period of time in which interest is accruing on any Advance on the basis of the Eurodollar Rate, no prepayment shall be made except on a day which is the last day of the Interest Period pertaining thereto. If the whole or any part of any Eurodollar Advance is prepaid by reason of acceleration or otherwise, the Borrower shall, upon the Bank's request, promptly pay to and indemnify the Bank for all costs and any loss (including interest) actually incurred by the Bank as a consequence of such prepayment. -2- I. INDEMNIFICATION FOR EURODOLLAR RATE COSTS. During any period of time in which interest on any Advance is accruing on the basis of the Eurodollar Rate, the Borrower shall, upon the Bank's request, promptly pay to and reimburse the Bank for all costs incurred and payments made by the Bank by reason of any future assessment, reserve, deposit or similar requirement or any surcharge, tax or fee imposed upon the Bank or as a result of the Bank's compliance with any directive or requirement of any regulatory authority pertaining or relating to funds used by the Bank in quoting and determining the Eurodollar Rate. J. CONVERSION FROM EURODOLLAR RATE TO VARIABLE RATE. In the event that the Bank shall at any time reasonably determine that the accrual of interest on the basis of the Eurodollar Rate (i) is infeasible because the Bank is unable to determine the Eurodollar Rate due to the unavailability of U.S. dollar deposits or contracts in an amount approximately equal to the amount of the relevant Advance and for a period of time approximately equal to relevant Interest Period or (ii) is or has become unlawful or infeasible by reason of the Bank's compliance with any new law, rule, regulation, guideline or order, or any new interpretation of any present law, rule, regulation, guideline or order, then the Bank shall give telephonic notice thereof (confirmed in writing) to the Borrower, in which event the Eurodollar Advance shall be deemed to be a Reference Rate Advance and interest shall thereupon immediately accrue at the Variable Rate. 1.03 DISBURSEMENT OF PROCEEDS FROM ADVANCES. Any Advance made hereunder shall be conclusively presumed to have been made to and for the Borrower's benefit when the proceeds of such Advance are disbursed in accordance with the Borrower's instructions or deposited into a checking account of the Borrower maintained at the Bank. 1.04 LOAN FEE; COMMITMENT FEE. The Borrower agrees to pay to the Bank (i) no later than thirty (30) days after the date of this Agreement, a non- refundable loan fee in the amount of $37,500.00 and (ii) from the date hereof to the termination of this Agreement a fee equal to 0.25% per annum of the average daily amount of the Line of Credit, payable in arrears for the immediately preceding calendar quarter on the 15th day of each January, April, July and October of each year and payable at the termination date of this Agreement for the immediately preceding calendar quarter, if not previously paid, and for the then current calendar quarter. With respect to the first and last fee payments as required under this section 1.04(ii), such fees shall be calculated pro rata with respect to the number of days during the applicable time periods for which the Line of Credit has been in effect.
